JP5744491B2 - Monitoring system and alarm - Google Patents

Description

The present invention relates to a monitoring system and an alarm device in which a plurality of alarm devices that detect an abnormality such as a fire and output an alarm are linked to each other.

  Conventionally, alarm devices that detect and warn of abnormalities such as fires and gas leaks in homes have become widespread. Of these, residential fire alarms are referred to as residential alarms.

  In such a house alarm, the sensor unit and the alarm unit are integrally provided in the house alarm, and when a fire is detected from the detection signal of the sensor unit, a fire alarm sound of a predetermined pattern is output from the alarm unit. It is easy to install and inexpensive because it can be used for fire monitoring and alarms without requiring a dedicated receiving facility, etc. Yes.

  In addition, by communicating between multiple home alarms, when a fire alarm sound is output from any home alarm, an interlocked home police that outputs a fire alarm sound in conjunction with other home alarms. A vessel system has also been proposed.

  In such an interlocked house alarm system, when a fire is detected by the house alarm, the interlocking house alarm that detects the fire has a predetermined pattern of fire alarm sound including a message and an alarm sound, for example, “Woo Woo On the other hand, for the alarm device that is linked, for example, a fire alarm sound that indicates the link destination is displayed, for example, “Please check if another fire alarm is activated. I am trying to output.

  In addition, in the conventional house alarm, automatic inspection to detect sensor failure such as sensor abnormality such as sensor or detection circuit, voice notification circuit failure, sensitivity abnormality due to contamination, etc. is periodically executed and stored in the memory. When the alarm stop switch is operated in a normal state where a fire alarm is not output, an inspection instruction is accepted and the result of the automatic inspection stored in the memory is notified.

  In addition, in the case of residential alarms that operate on battery power, the battery voltage is periodically checked internally, and when the battery voltage drops below a predetermined level, a low battery failure is detected and a low battery warning (low battery) (Failure alarm) is output, and the notification method is devised to ensure that the battery is replaced. (Patent Document 1)

  On the other hand, at the time of an inspection operation based on an inspection instruction operation, there is also an information that includes the presence or absence of a low battery failure in addition to other failures in the inspection result.

  If there is no problem, the inspection result notification is the same as the fire alarm sound, for example, the alarm sound such as “Woo Woo fire alarm activated” and the alarm sound such as “Pick is normal”, and the sound output function of the speaker. Output once at a relatively low volume to check. On the other hand, if a low battery failure is detected, a failure warning sound such as “Battery dead” is output a predetermined number of times, and if a sensor failure is detected, a failure warning sound such as “pick failure” is output a predetermined number of times. Output.

  As described above, in the conventional house alarm, the inspection function for detecting a low battery failure or a sensor failure is automatically performed regularly inside and stored in the memory when a failure is detected. The voice notification is performed when the inspection instruction is operated in the normal state as described above.

  In this way, instead of notifying the result of the inspection that is automatically performed inside each time or every time the occurrence of a failure is detected, the notification is made when the inspection instruction operation is performed manually. , Notifying an emergency (not urgent) failure regardless of the presence / absence of the user may lead to wasteful power consumption, or output a notification sound during sleeping at night This is to alleviate the possibility of annoying the user. Needless to say, the notification may be started at the time when the occurrence of a partial failure that requires urgent notification is determined regardless of this.

  Here, especially with regard to the sound notification function (output function for alarm sound, etc.), for example, even if the resident alarm automatically performs sound output operation at a timing not intended by the user, the sound is actually In situations where output is not possible, the user cannot confirm it.

In addition, even if the sound output function is out of order, if it is output by display, for example, if there is a mechanical failure (for example, diaphragm damage) in the speaker as the sound output device, Therefore, it is necessary to confirm the presence / absence of an output abnormality with the sense of hearing by the user's intention.

Japanese Patent No. 3895646 Utility Model Registration No. 3154579

  For this reason, the inspection instruction operation from the outside by the user should be surely executed at a predetermined frequency, and when this is not performed properly, for example, when there is a failure in the sound notification function of the resident alarm, As a result that the user cannot recognize this, for example, there is a danger that the user is notified with the fire alarm function being impaired.

  Nonetheless, in such a conventional interlocking type houseguard, the instruction manual only recommends that it should be inspected at predetermined intervals, and manual inspection is performed. It is left up to the user to determine whether or not to actually perform the manual inspection and at what timing, so if there is no inspection instruction operation by the user for a long time, the inspection will be performed at an appropriate cycle. In the event of a fire, there was a risk that the home alarm would not function properly due to a failure.

  Such a problem is not limited to the above example, and is common in the case of leaving some inspection to manual implementation based on the intention of the user in all alarm devices including a residential alarm device.

An object of the present invention is to provide a monitoring system and an alarm device that allow a user to appropriately perform an inspection instruction operation on an interlocked alarm device that operates in cooperation with each other.

1st invention of this application is the monitoring system which provided the some alarm device which observes an environmental change, detects the abnormality of a monitoring area | region, and alert | reports in cooperation with each other,
For each of the multiple alarms,
An operation unit for instructing execution of inspection processing by a predetermined inspection operation from the outside;
An inspection processing unit for executing a predetermined inspection process and notifying an inspection result when an inspection operation is detected;
An inspection timer for setting and measuring a predetermined cycle of an inspection time that requires an inspection operation;
When the inspection operation is detected before the arrival of the predetermined cycle , the inspection result is notified and the inspection timer is restarted, and the event signal indicating the inspection request is effectively received from another alarm device before the arrival of the predetermined cycle. In such a case , the user is informed of the inspection request information for requesting the inspection operation, and the inspection timer is restarted. When the arrival of a predetermined period by the inspection timer is detected , the inspection request information is notified and the other alarm device is notified. An inspection request management unit that transmits an event signal indicating an inspection request and restarts the inspection timer;
Is provided.

Here, the inspection request management unit of the alarm device initializes a master mode that allows notification of inspection request information based on the inspection timer at the time of start-up, and checks from other alarm devices before the arrival of a predetermined period by the inspection timer. When the event signal indicating the request is received effectively , the master mode is canceled and the slave mode is set to prohibit the notification of the inspection request information based on the inspection timer.

After setting the slave mode, the inspection request management unit of the alarm device cancels the slave mode if it does not receive an event signal indicating an inspection request from another alarm device even after the predetermined period of the inspection timer has elapsed. Reset the master mode.

  The inspection request management unit of the alarm device cancels the slave mode if it does not receive an event signal indicating an inspection request from another alarm device even after a predetermined waiting time has elapsed since the arrival of the predetermined period by the inspection timer. To reset the master mode. Here, the predetermined waiting time is varied for each alarm device.

  The predetermined period set in the inspection timer may be different for each alarm device.

  The inspection request management unit of the alarm device notifies the switching to the master mode when the slave mode is canceled and the master mode is set.

Alarm device inspection request management unit, to perform the inspection request displayed on the notification unit as inspection request information, if the first waiting time is not detected the inspection operation of the operation unit also passed, stops an inspection request indication To do.

The inspection request management unit of the alarm device causes the notification unit to display the inspection request as inspection request information, and if the inspection operation of the operation unit is not detected even after the second waiting time has elapsed, an inspection request is issued from the notification unit. If the inspection operation of the operation unit is not detected even if the first waiting time elapses during the output of the alarm sound , the inspection request display and the alarm sound are stopped.

Inspection request management unit of the alarm device, when the first waiting time is not detected the inspection operation of the operation unit also passed, by changing the predetermined cycle is set to check the timer to a short predetermined period re Start it.

Inspection request management unit of the alarm device, when the state in which the first waiting does not detect the inspection operation of the operation portion even after continuous multiple stepwise shorter inspection period is set to check the timer Change to the inspection cycle and restart.

The inspection processing unit of the alarm device outputs a failure alarm from the notification unit and stores the failure information in the storage unit when the event detection unit detects the inspection operation of the operation unit and stores the failure information in the storage unit. When it is determined that normal is not stored, a predetermined confirmation sound is output from the notification unit.

(Effects of basic invention and first invention)
According to the monitoring system of the present invention, an inspection request display for requesting an inspection operation is performed when a predetermined inspection cycle has elapsed and the inspection time has arrived without any inspection operation being performed in any of a plurality of alarm devices. When the user who notices this display performs an inspection operation, a predetermined inspection process is executed, the result is notified, and the user who has performed the inspection operation can directly recognize the result.

The event signal indicating an inspection request to the other alarm devices (inspection request event signal) is transmitted, inspection request indication in other alarm devices side is performed in conjunction with the arrival of the manual inspection timing to the user in the vicinity Can be informed.

In addition, the alarm device that first detects the arrival of the manual inspection due to the elapse of the inspection cycle maintains a master mode that allows inspection requests based on its own inspection timer, which is based on its own inspection timer. An alarm device that has effectively received an inspection request event signal from another alarm device before the arrival of the inspection cycle cancels the initially set master mode, sets a slave mode that prohibits inspection requests based on its own inspection timer, and thereafter In addition, inspection request notification is performed by a plurality of alarm devices in synchronization with the inspection timer of the alarm device maintaining the master mode, and variations in the inspection cycle among the alarm devices can be prevented.

In addition, when an alarm operating in the master mode fails, the other alarms operating in the slave mode do not receive the inspection request event signal and the inspection cycle based on their own inspection timer. At the timing when a predetermined time has passed since the arrival of the alarm, the previous slave mode is canceled and the master mode is set again. Of these, the alarm device that has reached the inspection cycle based on its own inspection timer first maintains the master mode. The remaining alarm devices that have received an event signal indicating inspection from this alarm device are switched to slave mode, and the relationship between the master alarm device and the slave alarm device is automatically reconstructed and the inspection cycle varies between each alarm device. Can be prevented.

If the event signal indicating the inspection request is not received from another alarm device even after a predetermined waiting time has elapsed since the arrival of the predetermined period by the inspection timer, the slave mode is canceled and the master mode is reset. prevention but, by varying the waiting time for this to each alarm device, it and a plurality of alarm devices is to be the master mode simultaneously, that at the same time check request event signal from the alarm device as the master mode is transmitted it can.

The predetermined period is set to check the timer, also by varying every alarm, it and a plurality of alarm devices is to be the master mode simultaneously, at the same time check request event signal from the alarm device as the master mode is transmitted Can be prevented.

(Effect of the second invention)
According to the monitoring system of the present invention, one of a plurality of alarm devices that perform alarms in cooperation with each other is a master alarm device, and the remaining is a slave alarm device, and the master alarm device notifies an inspection request based on an inspection timer. The slave alarm device does not have an inspection timer, and the slave alarm device is synchronized with the master alarm device by effectively receiving the inspection request event signal from the master alarm device and notifying the inspection request. Interlocked inspection request notification can be performed to prevent variations in the inspection cycle between alarm devices.

(Effects common to the first and second inventions)
In addition, the inspection result notification is not limited to the failure alarm sound when a failure is detected, and when a failure is not detected, a predetermined confirmation sound indicating normality is output to output a sound output function, for example, a speaker. The voice output function can be judged by the user's hearing.

  Also, if there is no inspection operation even after the specified waiting time has elapsed for the inspection request display, a request sound including an inspection request message is output to alert the user strongly and the user stays at home. If this is the case, it is possible to reliably notify the arrival of the manual inspection time and prompt the inspection operation.

Also, if the inspection timer is restarted without detecting the inspection operation even after the predetermined waiting time has elapsed for the inspection request display, the inspection that will come next can be performed by changing the inspection period to a shorter period and restarting it. It is possible to notify the inspection operation request promptly so that the manual inspection non-execution period does not become too long.

  FIG. 1 is an explanatory view showing an example of an installation state of a monitoring system using a residence guard according to the first invention of the present application for a house. In the example of FIG. 1, a wireless system that detects and interlocks with a fire in each of the warning areas (monitoring areas) of the kitchen, living room, children's room, master bedroom, and staircase provided in the house 24. House alarms (fire alarms for houses) 10-1 to 10-6 are installed. Hereinafter, the housing alarm devices 10-1 to 10-6 are collectively referred to as the housing alarm device 10 without being distinguished from each other.

  The home alarm device 10 has a function of wirelessly transmitting and receiving event signals to each other, and monitors whether or not a fire has occurred in each monitoring area corresponding to each part of the house. If a fire has occurred in the kitchen of the house 24, the home alarm device 10-1 detects the fire and starts an alarm. Detecting this fire and initiating an alarm is referred to as “reporting” at the home alarm.

  When the home alarm device 10-1 issues a report, the home alarm device 10-1 functions as an interlock source, and an event signal (indicating a fire) is sent to the other home alarm devices 10-2 to 10-6 as the interlock destination. (Fire event signal) is transmitted wirelessly. When the other home alarm devices 10-2 to 10-6 have received an event signal indicating the occurrence of a fire from the home alarm device 10-1 as the interlock source, an alarm operation as an interlock destination by an alarm sound and an alarm display I do.

  Here, when the group code included in the received event signal matches the group code registered in the memory and the signal content is normally recognized, the resident alarm 10 confirms that the event signal has been received effectively. I try to detect it. In addition, the event signal transmitted from the home alarm device 10 includes a source code using a serial number or the like as identification information indicating the source home alarm device. In addition, the residence police device 100 which received the event signal effectively performs relay transmission of the event signal as needed.

  As an alarm operation of the home alarm device 10-1 that is the interlock source, for example, a fire alarm sound is output by a voice message such as “Please confirm that the Woo Woo fire alarm has been activated”. On the other hand, the interlocking house alarms 10-2 to 10-6 output a fire alarm sound by a voice message such as “Please confirm that another fire alarm has been activated”.

  Moreover, as an alarm display accompanying the fire alarm of the residence police device 10-1 which became the interlocking source, for example, an LED is lit. On the other hand, in the interlocking residence police 10-2 to 10-6, the LED blinks. As a result, the alarm display by the LED in the interlock source alarm and the interlock destination alarm can be distinguished.

  The interlocking source LED may be blinking, and the interlocking destination LED may be blinking, and the blinking or blinking of the same LED for any of the interlocking source alarm and the interlocking destination alarm, or blinking or blinking with a different cycle or duty. It may be a display. Further, for example, a red LED and a yellow LED may be provided, and the two-color display may be performed such that the interlocking source drives the red LED and the interlocking destination drives the yellow LED. Of course, a two-color LED capable of emitting both red and yellow by combining two LEDs can be adopted.

  When the alarm stop switch is operated in a state in which the house alarm 10 is emitting an alarm sound, the alarm sound and alarm display stop processing is performed.

  At this time, for example, when an alarm stop operation is performed in the home police device 10-1, which is the interlocking source, the alarms (alarm sound output and / or alarm display output) of all the home police devices 10 are stopped and interlocked. When the alarm stop operation is performed in any of the previous home police devices 10-2 to 10-6, the alarm of the home watch device 10-1 of the interlocking source does not stop, and the home watch device of the interlocking destination The alarm of 10-2 to 10-6 is stopped.

  Further, the home alarm device 10 automatically executes a monitoring process for determining a low battery failure from a drop in the power supply voltage supplied from the battery power source in the background at every predetermined period (built-in test). The result of this built-in test is updated and held in its own storage unit.

  In addition, when the inspection switch is operated, the home alarm device 10 determines a low battery failure based on the built-in test result, and when it is memorized, it outputs, for example, a “low battery” alarm as a low battery failure alarm a predetermined number of times. When the low battery failure is not determined, for example, a confirmation sound of “pick is normal” is output once in order to confirm the speaker operation.

  Further, the home alarm device 10 executes a built-in test for discriminating a sensor failure in the same manner as the low battery failure, and updates and holds the result of the built-in test in its own storage unit.

  In addition, the built-in test can be similarly performed and the results stored for the voice notification circuit, the presence / absence of various circuit failures, and the sensitivity abnormality due to contamination or the like.

  In addition, when the inspection switch is operated and the sensor failure is stored as a built-in test result, the home alarm device 10 repeatedly outputs, for example, “pick failure” as a failure alarm sound from the speaker, and outputs the LED. For example, it blinks.

  When the inspection switch is operated and the sensor failure is stored as a built-in test result, the home alarm device 10 repeatedly outputs, for example, “battery dead” as a sensor failure alarm and outputs an LED, for example. Flashes.

  On the other hand, when the sensor failure is not determined, for example, a confirmation sound of “pick is normal” is output once to confirm the speaker operation.

  In addition, the home alarm device 10 includes an inspection timer, and when a predetermined inspection cycle is counted by the inspection timer, for example, when an inspection time that is once every 30 days arrives, inspection request information for requesting an inspection operation of the inspection switch is displayed on the LED 22, for example, Notify by blinking the pattern, and at the same time, send an inspection request event signal to other resident alarms, and even resident alarms that have received this effectively notify similar inspection request information and encourage the user to perform the inspection operation It seems to be.

  In addition, it does not depend on the built-in test as described above (inspection result notification based on the contents stored in the result), but when the inspection switch is operated (inspection operation), various fault detection operations are performed (real-time test), and the result Or a built-in test and a real-time test may be divided according to the type of failure to be detected.

  In addition, it is not necessary to report the results of all faults during manual inspections by operating the inspection switch. Depending on the type of fault, the built-in test results can be automatically notified by appropriate methods even when the inspection operation is not performed (failures). Alarm output).

  For example, a low battery failure is automatically notified when it is detected by a built-in test, and further an event signal is sent to another resident alarm to notify it in conjunction, and then a periodic notification timer is used. Every time when the periodic periodic notification time is detected, notification by its own notification unit or transmission of an event signal indicating a low battery may be performed.

  In other words, the present invention can be applied regardless of the type and number of failures and the presence / absence of automatic notification of built-in test results as long as the inspection results are notified by the user's manual operation regarding the presence or absence of any failure. . This also applies to the second invention of the present application and other embodiments described later.

  When the arrival of a manual inspection time is detected by any of the residential alarms and the inspection request event signal is transmitted, the inspection timer of the residential alarm 10 is restarted by the corresponding residential alarm and is effectively received. The inspection timers provided for the respective home alarms are also restarted to synchronize with each other, and it is possible to prevent variations in the inspection time among the respective home alarms.

  In addition, after the inspection timer is synchronized, the inspection request notification due to the arrival detection of the inspection time of the inspection timer overlaps with the inspection request notification due to the effective reception of the inspection request event signal from another resident alarm. To avoid this, the master mode that allows inspection request notification based on its own inspection timer and the slave that prohibits inspection request notification based on its own inspection timer and allows inspection request display by effective reception of event signals A mode is provided, and the setting and cancellation are performed as follows.

  The home guard 10 operates by initially setting the master mode at the time of start-up upon power-on. In this state, for example, when the home alarm device 10-1 first detects the arrival of the inspection time by measuring the inspection period 30 days by the inspection timer, the inspection request notification is made and the inspection request event signal is sent to the home alarm device 10 as well. -2 to 10-6. When the house alarm device 10-2 to 10-6 receives the inspection request event signal effectively, the home alarm device 10-2 to 10-6 notifies the inspection request, cancels the initially set master mode, and sets the slave mode.

  As a result, the home alarm device 10-1 continues to operate in the master mode, and the other home alarm devices 10-2 to 10-6 operate by switching to the slave mode. Thereafter, the inspection of the home alarm device 10-1 is performed. The inspection request information notification of the residence guard 10 is performed in synchronization with the periodic detection of arrival of the inspection time based on the timer.

  The switching between the master mode and the slave mode is not limited to this method, and may be set in advance by switching means such as a setting switch.

  FIGS. 2A and 2B are explanatory views showing the appearance of the wireless interlocking smoke-type home alarm according to the first invention of the present application, in which FIG. 2A shows a front view and FIG. 2B shows a side view. The side provided with the attachment hook 15 is the upper side.

In FIG. 2, the housing of the residential alarm 10 according to the present embodiment includes a cover 12 and a main body 14. A protrusion is provided at the center of the cover 12, a plurality of smoke inlets are opened around the protrusion, and a smoke detector 16 is disposed in the inside thereof, so that smoke accompanying a fire flows into the smoke detector 16. A fire is detected when the specified concentration is reached. As the smoke detector 16, a smoke detector mechanism such as a scattered light type smoke detector can be applied.

  An acoustic hole 18 is provided on the lower left side of the cover 12, and a buzzer and a speaker are incorporated behind this so that an alarm sound and a voice message can be output. An alarm stop switch 20 is provided below the cover 12.

  In the present embodiment, the alarm stop switch 20 also functions as an inspection switch that instructs self-inspection of the function of the home alarm device 10. For example, when the alarm stop switch 20 is operated during the fire alarm output, the fire alarm is stopped, and when the alarm stop switch 20 is operated in a normal state, a predetermined function check is performed and the result is notified. Here, the normal state refers to a state where at least a fire alarm is being output or a failure alarm is not being output.

That is, when the alarm stop switch 20 is operated, the home alarm device 10 identifies whether it is an alarm stop instruction or an inspection instruction according to its own notification operation status, etc. Processing is performed based on this.

  The alarm stop switch 20 includes a switch cover formed of a translucent member and a push switch (not shown) arranged inside the switch cover. That is, when the switch cover is pressed, the push switch is pressed. In the vicinity of the push switch inside the switch cover, an LED 22 for displaying an alarm or the like is arranged as indicated by a dotted line. When the LED 22 lights up, flashes, or blinks, the operating light passes through the switch cover portion of the alarm stop switch 20. The operating state can be visually recognized from the outside.

  Further, a mounting hook 15 having an insertion hole in the substantially central portion thereof is provided at the upper part on the back side of the main body 14, and a screw or the like is screwed into the wall of the room to be installed and hooked through the insertion hole of the mounting hook 15. The residential alarm 10 can be fixedly installed on the wall surface in a so-called wall-hanging manner.

  In addition, in the residential alarm 10 of FIG. 2, although it has the smoke detection part 16, the smoke type residential alarm which detects the smoke which generate | occur | produces with a fire and detects the fire of a monitoring area is taken as an example, In addition to this, a thermal dwelling device equipped with a temperature detection element such as a thermistor that detects heat associated with a fire, a dwelling device that detects other environmental changes associated with a fire, an alarm device that detects a gas leak other than a fire, Various alarm devices that detect intruders, earthquakes, and other abnormalities (abnormalities), and alarm devices that combine these alarm devices are also included in the scope of the present invention. The monitoring system of the present invention may be configured by mixing these various alarm devices.

  FIG. 3 is a block diagram showing the configuration of the main part of a residential alarm provided in the monitoring system of the first invention of the present application. This is an example, and the separation and integration of each function can be performed arbitrarily. Each part or all of each function may be executed by software (program) or may be executed by hardware.

  Moreover, in FIG. 3, although it has shown about the residence guard 10-1 installed in the kitchen, it becomes the same structure also about the other residence guards 10-2 to 10-6.

  The home guard 10-1 includes a processor 28 known as a one-chip CPU. For the processor 28, a wireless communication unit 30 including an antenna 31, a memory 32, a sensor unit 34, a notification unit 36, an operation unit 38, and A battery power source 40 is provided.

  The wireless communication unit 30 is provided with a transmission circuit 42 and a reception circuit 44 so that event signals as interlocking signals can be transmitted and received wirelessly between the other residential alarm devices 10-2 to 10-6. As the wireless communication unit 30, in Japan, for example, STD-30 (wireless equipment standard of a low power security system wireless station) or STD-T67 known as a standard of a specific low power wireless station of 400 MHz band. It has a configuration that conforms to the standard for specific low-power radio station telemeters, telecontrol and data transmission radio equipment.

  Of course, when the wireless communication unit 30 is used outside Japan, the wireless communication unit 30 has contents compliant with the standard of the assigned wireless station in that region.

  The antenna 31, the transmission circuit 42, and the transmission processing unit 60 together function as a transmission unit, and the antenna 31, the reception circuit 44, and the reception processing unit 62 collectively function as a reception unit.

In the memory 32, a serial number 48, which is a serial number indicating the generation order or transmission order of event signals, a transmission source code 50 serving as residential alarm identification information for identifying each residential alarm, and the house 24 as shown in FIG. A group code 52 for configuring an interlocking group that performs interlocking alarms in each installed home alarm device 10 is stored.

  The serial number 48 is a code that is automatically generated and updated (e.g., incremented) in accordance with a predetermined rule every time an event signal is transmitted, for example, and is generated for each residential alarm. This is for managing the relay processing of event signals between alarm devices, particularly in wireless communication, but is not directly related to the present invention, so detailed description thereof will be omitted.

  As the transmission source code 50, for example, a 26-bit multi-bit code code is used so as not to be duplicated as the same code as any of the domestic alarms provided in the country, for example, the serial number of the emergency alarm is used.

  When the event signal is effectively received from the other alarm device 10, the house alarm device 10 can relay and transmit the event signal as necessary. However, the event signal is transmitted using the serial number 48 or the transmission source code 50. Signal relay transmission and re-relay transmission can be permitted or prohibited, and by performing processing that avoids unnecessary communication, optimal relay can be performed as necessary. In addition, for example, the event source signal relayed by the interlocking home resident alarm is added with the source code of the interlocking home resident alarm in addition to the source code of the interlocking home resident alarm. It is also possible to determine whether re-transmission is possible or not from the transmitter transmission source code. In addition, relay transmission permission and prohibition can be set for each event content indicated by the event signal.

  The group code 52 is, for example, a code that is commonly set for a plurality of residential alarms that configure the interlocking group, and the reception processing unit 62 stores the group code included in the event signal received by the wireless communication unit 30 in the memory 32. When it matches the registered group code 52, this event signal will be processed as a valid signal, so it is installed in a neighboring house, etc. Unnecessary interlocking can be avoided.

  The group code 52 does not necessarily have to be the same code for each house alarm, and by performing calculations based on this, it can be determined whether the group to which the self belongs and the group to which another house alarm belongs are the same. Anything is fine. Registration of the group code 52 is performed by an appropriate method such as setting of an external switch or automatic registration using a communication function before shipment or before starting operation.

  Further, for example, a low battery failure flag 78 or a sensor failure flag 80 is updated and stored as a detection result of each failure as a failure detection result by periodic failure monitoring (built-in test) in the background. Further, the memory 32 is provided with an inspection timer 84 used for a notification process that measures the arrival of a periodic inspection timing and prompts the user to perform a manual inspection operation. Note that the inspection timer 84 may not be arranged in the memory 32 but may be arranged on a program executed by the processor 28, or may be provided as another timing circuit.

  The sensor unit 34 is provided with a smoke detector 16 that detects smoke based on the scattered light smoke detection principle and outputs a detection signal corresponding to the smoke density. As described above, instead of the smoke detector 16, the sensor unit 34 detects elements that change the temperature due to a fire and outputs a detection signal, and detects other environmental changes caused by the fire and outputs a detection signal. Various elements and sensors may be provided.

  The notification unit 36 is provided with a speaker 56 that is an acoustic output device that outputs an alarm sound and the like, and an LED 22 that displays an alarm. The speaker 56 outputs a voice message, an alarm sound, and the like from a voice synthesis circuit unit (not shown) through an amplification unit (not shown) based on various data held by itself. The LED 22 displays an abnormality such as a fire by blinking, blinking, or lighting. Instead of the speaker 56, a buzzer or the like may be used. Further, instead of the LED 22, a two-color LED, a liquid crystal display, or the like may be provided. Of course, an LED and a liquid crystal display may be provided together.

  The operation unit 38 is provided with an alarm stop switch 20 that also serves as an inspection switch. The alarm stop switch 20 functions as an alarm stop switch when the alarm unit 36 outputs a warning sound of a fire or a failure from the notification unit 36 or when an alarm display is performed by the LED 22.

  For example, if the alarm stop switch 20 is operated during the alarm output indicating the interlock source, the alarm sound and the alarm display are stopped. On the other hand, if the alarm stop switch 20 is operated during the alarm output indicating the interlock destination, the alarm sound is stopped. Alarm stop processing is performed such that the alarm display is maintained or stopped, or stopped after a predetermined time from the stop of the alarm sound.

  In a normal state in which a fire alarm or a failure alarm indicating the interlock source or the interlock destination is not output, the alarm stop switch 20 functions as an inspection switch. When the alarm stop switch 20 is operated in this state, a predetermined inspection operation is detected. Then, the set state of the low battery failure flag 78 or the sensor failure flag 80 recorded in the memory 32 as a built-in test result is determined, and if any failure flag is set, the corresponding failure from the speaker 56 of the notification unit 36. Output fault alerts such as voice messages that indicate the contents. If a plurality of failure flags are set, voice messages indicating the corresponding failure contents are sequentially output.

  If no failure flag is set in the memory 32, the inspection result is normal, so that a sound message such as “pick is normal” is used as a confirmation sound for confirming the sound output function from the speaker 56, for example. Is output once. At this time, if you want to check the most important fire alarm sound among the sound outputs, output a voice message alarm with the same content and volume as the fire alarm sound, for example, “Please check that the Wu Woo fire alarm has been activated”. Then, in order to indicate that this is an output accompanying the inspection, for example, a voice message “pick is normal” may be output.

  Note that the inspection process by the inspection operation does not notify the inspection result based on the result of the built-in test, but may notify the result by a real-time test. That is, when the operation of the alarm stop switch 20 is detected in a normal state (when inspection is instructed), for example, a predetermined inspection operation including battery failure detection and sensor failure detection is performed and the result is notified. good.

  In addition, when the alarm stop switch 20 is operated during a fault alarm, a predetermined check operation including battery fault detection and sensor fault detection is performed again, and the fault alarm stop process is performed after notifying the result. Also good. In this way, for example, a failure alarm stop process is performed after rechecking a sensor failure or the like, so that the failure failure state can be recognized more clearly by the user. At this time, if the failure state has been resolved (failure recovery), for example, a voice message such as “the failure has been resolved” may be output, and the process may proceed to failure stop (recovery) processing.

  The battery power source 40 uses, for example, a lithium battery or an alkaline battery having a predetermined number of cells, and has a battery capacity of, for example, 10 by reducing the power consumption of the entire circuit unit including the wireless communication unit 30 in the residential alarm 10-1. The battery life of the year is guaranteed.

In the processor 28, functions realized by executing the program include an event detection unit 58, a transmission processing unit 60, a reception processing unit 62, an abnormality notification processing unit 64, a failure detection unit 66, a failure notification processing unit 72, and an inspection processing unit 74. In addition, the failure detection unit 66 is provided with the functions of a low battery failure detection unit 68 and a sensor failure detection unit 70, for example. Of course, instead of one or both of the low battery failure detection unit 68 and the sensor failure detection unit 70, or in addition to one or both, an appropriate failure monitoring unit can be provided.

  The event detection unit 58 includes the presence / absence of a fire detected based on the detection signal output from the smoke detector 16 provided in the sensor unit 34, the presence / absence of an alarm stop instruction input by the operation unit 38, the presence / absence of an inspection instruction, and the sensor unit 34. The detection signal output from the smoke detector 16 provided in the fire is reduced and the fire detection state is resolved, the fire is restored, the presence of sensor failure or low battery failure by the detection signal from the failure detection unit 66, the time of the inspection timer 84 An event such as the arrival of a manual inspection cycle is detected. Further, the event detection unit 58 detects the presence / absence of event signal effective reception and the event content obtained as a result of decoding the event signals from the other residential alarm devices 10-2 to 10-6 via the reception unit.

  The transmission processing unit 60 detects the fire based on the detection signal output from the smoke detector 16 by the event detector 58, stops the alarm or inputs an inspection instruction by the operation unit 38, and the detection signal output from the smoke detector 16 decreases and fires. When a self-event is detected, such as a fire recovery that eliminates the detection state, an event signal indicating the detected event content is sent to the linked resident police through the transmission circuit 42 and the antenna 31 of the wireless communication unit 30. Send. In addition, the transmission processing unit 60 relays and transmits event signals that are effectively received from other mortgages as necessary.

  The reception processing unit 62 receives and decodes the event signals from the other mortgages 10-2 to 10-6 via the antenna 31 and the reception circuit 44 of the wireless communication unit 30.

  The abnormality notification processing unit 64 receives a signal from the event detection unit 58 when the event detection unit 58 detects a fire as an abnormality to be detected in its own monitoring area, and indicates an interlock source from the speaker 56 of the notification unit 36. In addition to outputting sound, the LED 22 is turned on, for example, to display an alarm indicating an interlocking source, and as an interlocking source, an event signal indicating a fire is sent to the other residential alarm devices 10-2 to 10-6 to the transmitter. Send it.

  Specifically, when the event detection unit 58 detects a fire based on the smoke detection signal of the smoke detection unit 16 provided in the sensor unit 34, the abnormality notification processing unit 64 indicates that fact from the event detection unit 58. Based on the received signal, the alarm unit 36 is controlled to repeatedly output an alarm sound indicating the link source from the speaker 56, for example, “Woo Woo is a fire, please confirm”, and the LED 22 is turned on. Control is performed to display an alarm indicating the interlocking source, and further, an event signal indicating a fire is directed from the antenna 31 to the other residential alarm devices 10-2 to 10-6 via the transmission processing unit 60 and the transmission circuit 42. Send it.

  In addition, the abnormality notification processing unit 64 notifies the event that the fire event signal has been effectively received from any of the other home alarm devices 10-2 to 10-6 by the reception circuit 44 of the wireless communication unit 30 via the reception processing unit 62. When detected by the detection unit 58, an alarm sound (notification sound) indicating the interlocking destination is repeatedly output from the speaker 56 of the notification unit 36, for example, “Please confirm that another fire alarm has been activated”. At the same time, the LED 22 is controlled to blink, for example, to display an alarm indicating the interlocking destination.

  Further, the abnormality notification processing unit 64 detects the operation of the alarm stop switch 20 during the output of the fire alarm sound indicating the interlocking source or the fire alarm sound indicating the interlocking destination, or other residential alarm devices 10-2 to 10-6. When the effective reception of an event signal (alarm stop event signal) indicating an alarm stop from any of the above is detected, the alarm unit 36 is controlled to stop the output of the fire alarm by the voice message from the speaker 56 and the alarm display of the LED 22 Let At this time, the alarm display by the LED 22 may be stopped after a predetermined time from the stop of the alarm sound. It should be noted that during the output of the fire alarm indicating the interlock source, at least the output of the alarm sound may be continued even if the event signal indicating the alarm stop is effectively received.

In the present embodiment, the failure detection unit 66 is provided with functions of a low battery failure detection unit 68 and a sensor failure detection unit 70.

The low battery failure detection unit 68 directly or indirectly observes the power supply voltage supplied from the battery power supply 40 at a predetermined measurement time interval, for example, T1 = 4 time intervals, via a voltage detection circuit (not shown). A built-in test is performed in which A is read by A / D conversion and compared with a predetermined threshold voltage. When the voltage is less than the threshold voltage, a low battery failure is preliminarily determined. Further, a low battery failure preliminary determination is continuously performed a predetermined number of times. Sometimes, a low battery failure is determined (determined) and detected, and a low battery failure flag 78 is set and updated and stored in the memory 32.

As a built-in test similar to a low battery failure, the sensor failure detection unit 70 performs A / D conversion on the smoke detection signal output from the smoke detection unit 16 of the sensor unit 34 at a predetermined measurement time interval, for example, T2 = 1 second interval. The average value of the detected data for the last 10 minutes held in the buffer area of the memory 32 is obtained every predetermined time interval T3 = 10 minutes, for example, and the average value is read. When it falls below a predetermined reference level (referred to as the zero point level), it is determined that the sensor unit 34 is faulty as being in an output stop state or the like, and a sensor fault flag 80 is set and updated and stored in the memory 32.

  The reason why the 10-minute average value of the smoke detection signal is below the zero point level is that the light emitting element or the light receiving element provided in the smoke detector 16 is broken, the output signal line from the light receiving element is broken, the light receiving amplifier is stopped, etc. Since there is a high possibility that the failure has occurred, the sensor failure is assumed.

  Note that, in the case of a thermal house alarm or the like in which a temperature detection element such as a thermistor is provided in the sensor unit 34, a sensor failure can be similarly detected by various processes. In addition, disconnection of the output line to the speaker 56, other circuit failures, communication abnormalities, and the like can be similarly monitored. For such a failure, the same processing as the sensor failure is performed after detection.

As described above, the built-in tests of the low battery failure detection unit 68 and the sensor failure detection unit 70 in this embodiment are automatically executed in the background.

The inspection processing unit 74 stores a low battery failure flag 78 in the memory 32 when the event detection unit 58 detects an inspection instruction operation (inspection instruction input) by operating the alarm stop switch 20 that functions as an inspection switch in a normal state. If it is determined that it has been detected, the failure notification processing unit 72 repeatedly outputs, for example, “Battery is dead” a predetermined number of times, the LED 22 blinks, for example, and the transmission unit transmits a low battery failure event signal to another By sending it to the home alarm device 10-2 to 10-6, the alarm device for the low battery failure alarm indicating the interlock destination can be used as the alarm device for the interlocking destination that has effectively received this. The voice message “It's out” is output, and a blinking display with a pattern different from the link source is displayed.

  The inspection processing unit 74 determines that the sensor failure flag 80 is set and stored in the memory 32 when the event detection unit 58 detects an inspection instruction operation (inspection instruction input) by operating the alarm stop switch 20. For example, the failure notification processing unit 72 repeatedly outputs “pick failure” a predetermined number of times, for example, causes the LED 22 to blink, and further transmits a sensor failure event signal to the other residential alarm devices 10-2 to 10-6 by the transmission unit. By sending it to, it will output a voice message `` Pick another alarm device is out of battery '' as an alarm sound of the sensor failure alarm indicating the interlocking destination at the home alarm device that has received this effectively, A blinking display with a pattern different from the linkage source is performed.

  In this way, when the alarm stop switch 20 is operated for manual inspection, since there is always an operator in front of the house alarm, it is possible to reliably notify low battery failure and sensor failure, and the inspection result. Can be reliably confirmed by the operator's hearing.

  When the event detection unit 58 detects an inspection instruction operation (inspection instruction input) by operating the alarm stop switch 20, the inspection processing unit 74 stores both the low battery failure flag 78 and the sensor failure flag 80 in the memory 32. If not, it is determined that there is no failure and is normal. In this case, in order to confirm the sound output function for confirming that the alarm sound or the like is normally output from the speaker 56 provided in the notification unit 36, “ A confirmation sound is output once by the voice message “Pip is normal”.

  When the event detection unit 58 detects an inspection instruction operation (inspection instruction input) by operating the alarm stop switch 20, the inspection processing unit 74 causes the failure detection unit 66 to detect low battery failure and sensor failure (automatic inspection). ) May be executed again, and if a failure is detected at this time, a failure alarm is output, and if normal is detected, a confirmation sound may be output from the speaker 56. Thereby, the latest inspection result can be notified.

The inspection request management unit 76 uses the inspection timer 84 disposed in the memory 32 in cooperation with the event detection unit 58 to notify the notification unit 36 of the arrival of the manual inspection timing. That is, the event detection unit 58 detects the arrival of the manual inspection timing of the inspection timer 84 and inputs the detection result to the inspection request management unit 76 to notify the arrival of the manual inspection timing.

  The inspection timer 84 sets a predetermined inspection cycle that requires a manual inspection operation, for example, a 30-day inspection cycle, by the alarm stop switch 20 provided in the operation unit 38, and causes the time to be measured. The inspection cycle may be different for each house alarm, for example, 30 days for a certain house alarm, 31 days, 32 days for other house alarms.

  In this way, it is possible to reduce the probability that switching from the slave mode to the master mode, which will be described later, will be switched at the same time by a plurality of home alarms. It is possible to prevent the inspection request event signal from being simultaneously transmitted from the home alarm device. In addition, such an inspection period is not limited to said specific illustration.

  The inspection request management unit 76 initially sets a master mode that allows inspection request information to be notified based on the inspection timer 84 at the time of activation upon power-on, and before the arrival of the initial inspection cycle 30 days by the inspection timer 84. When the inspection operation of the alarm stop switch 20 is detected by the event detection unit 58, the inspection timer 84 is restarted after the inspection processing unit 74 performs the inspection result notification control on the notification unit 36.

  In addition, the inspection request management unit 76 cooperates with the event detection unit 58 to detect the arrival of the manual inspection timing after the 30-day inspection cycle by the inspection timer 84 has passed, and the monitoring processing unit 74 The inspection unit 36 outputs inspection request information for requesting the user to perform an inspection operation of the alarm stop switch 20 from the notification unit 36, and transmits an inspection request event signal to another residence police by the transmission unit including the transmission processing unit 60, the transmission circuit 42, and the antenna 31. Devices 10-2 to 10-6, and the inspection timer 84 is restarted (master operation).

In addition, if the event detection unit 58 detects the effective reception of the inspection request event signal from any of the other mortgages 10-2 to 10-6 before the inspection period 30 days by the inspection timer 84 arrives, The request management unit 76 causes the notification unit 36 to output inspection request information for requesting the inspection operation of the alarm stop switch 20 from the notification unit 36 via the inspection processing unit 74, and cancels the initially set master mode to the inspection timer 84. The slave mode that prohibits the notification of the inspection request information based on the effective reception of the inspection request event signal while prohibiting the notification of the inspection request information based on the setting is set.

  When the slave mode is set, the inspection request information based on the inspection timer 84 is not notified thereafter, and the inspection request information based only on the effective reception of the inspection request event signal from the other home alarm, that is, the master mode is set. The notification operation (slave operation) of the inspection request information synchronized with the inspection timer of the other residential alarm set is performed.

FIG. 4 is an explanatory view showing the cooperation operation of the inspection request information notification when the inspection request arrival unit is first detected by the inspection request management unit 76 provided in the residential police device 10-1 of FIG. In FIG. 4 (A), each residence guard 10 is provided with inspection timers 84-1 to 84-6, which are shown in a pseudo manner as an analog clock that rotates once every 30 days for ease of explanation. ing.

When the home alarm devices 10 are turned on and activated, the respective inspection timers 84-1 to 84-6 display arbitrary times, and time synchronization is not taken. Actually, when the registration operation such as the group code is performed for the home alarm device 10 that constructs the monitoring system at the factory or at the installation location, the battery power supply 40 is turned on almost at the same time. The time difference between the timers 84-1 to 84-6 is small.

If the operation is started in this state, for example, when the time of the inspection timer 84-1 of the home alarm device 10-1 first reaches the inspection cycle 30th and the arrival of the manual inspection time is detected internally, the home alarm device 10 is detected. -1 outputs inspection request information from its own notification unit 36 by, for example, blinking the LED 22, and also sends an inspection request event signal to the other mortgages 10-2 to 10- as shown by arrows in FIG. 6 and, based on the effective reception of the inspection request event signal, the other alarm devices 10-2 to 10-6 blink the LEDs 22 in a pattern different from the alarm device 10-1, for example. Thus, the inspection request information is notified, and the inspection timers 84-2 to 84-6 are restarted. As a result, the inspection timers 84-1 to 84-6 are synchronized as shown in FIG. It will be.

  In addition, the mortgage alarm device 10-1 maintains the initially set master mode thereafter (the master mode may be overwritten).

  On the other hand, the other residential alarm devices 10-2 to 10-6 cancel the initially set master mode and set the slave mode. In the slave mode, the check timer is hatched.

  For this reason, after the timekeeping synchronization of the timer is performed at the time of manual inspection of the home alarm device 10-1, the other home alarm devices 10-2 to 10-6 have their own inspection timers 84-2 to 84-6. The inspection request information is displayed depending on the inspection timer 10-1 of the resident alarm 10-1, and the variation in the inspection request information display timing among the resident alarms can be eliminated.

  FIG. 5 shows, for example, a case where the resident alarm 10-1 operating in the master mode fails in a state where the master-slave relationship is established and the time synchronization of the inspection timer is achieved as shown in FIG. It is explanatory drawing shown about the rebuilding process of the master slave relationship.

  In FIG. 5 (A), the home alarm device 10-1 operates in the master mode, the other home alarm devices 10-2 to 10-6 operate in the slave mode, and the inspection timers 84-1 to 84-6 are Synchronized. In this state, as shown in FIG. 5 (B), for example, some trouble occurs in the residential alarm device 10-1 operating in the master mode, and the inspection request event signal cannot be transmitted, or the inspection timer 84- It is assumed that an inspection request event signal based on detection of arrival of a manual inspection time due to timing of 1 is delayed for a predetermined period or longer.

  In this case, among the resident alarms that are operating normally except the resident alarm 10-1, for example, the time of the inspection timer 84-2 of the resident alarm 10-2 first reaches the inspection period 30 days and is manually operated. Assuming that the arrival of the inspection time is detected, the Dwelling Unit 10-2 cancels its own slave mode if it does not receive the inspection request event signal after a predetermined time has elapsed since the detection of the arrival of the inspection time. Set the master mode.

  In this way, the residential alarm device 10-2 that has become the master mode performs a master operation. That is, while notifying inspection request information from its own notification unit, an inspection request event signal is transmitted to the other residential alarm devices 10-1, 10-3 to 10-6. The resident alarm device that has received this inspection request event signal effectively performs inspection request information notification as a slave operation, and then operates in the slave mode.

  For this reason, it replaces with the faulty residence police device 10-1, and the residence police device 10-2 becomes a master mode, rebuilds the master-slave relationship of the inspection request, and prevents the variation of the inspection time between each residence police device. be able to.

  Here, the predetermined waiting time from detection of arrival of inspection time by the own inspection timer, which is a condition for the progress of the residence alarm 10-2 to cancel the slave mode and become the master mode, is, for example, the residence police 10 -2 is 1 hour, and the residence police 10-3 is 2 hours, for example, different times for each of the residence guards. In this way, a plurality of residence guards are simultaneously switched from the slave mode to the master mode. Probability can be lowered, and it is possible to prevent a plurality of home alarm devices from simultaneously entering the master mode and preventing an inspection request event signal from being simultaneously transmitted from the home alarm device in the master mode. Such a predetermined waiting time is not limited to a specific example.

  In addition, in the resident guard 10-2 which becomes the master mode instead of the resident guard 10-1 which is the master mode, when performing this mode switching, for example, "inspection request from another alarm device" This may be notified by a voice message such as “Cannot receive and switch to master mode”.

  In this way, it is possible to notify the user that some trouble has occurred in the home alarm device 10-1, which is the master mode, or in its own signal reception function. Furthermore, it is preferable that a user who has noticed this can provide means for confirming whether the mode currently set for each home alarm is the master mode or the slave mode. For example, this can be notified by a display operation or a voice by a switch operation or the like, and in this way, it becomes easy to specify a defect or the like of the residential alarm device 10-1 in the above example.

  FIG. 6 is an explanatory diagram schematically showing the format of the event signal used for the interlocking alarm in this embodiment. In FIG. 6, the event signal 46 includes a serial number 48, a transmission source code 50, a group code 52, and an event code 54. Note that, for an event signal to be relayed, both the source code of the link source and its own source code as the relay source are added.

Here, the event code 54 is a code representing the event content such as fire, gas leak (for example, a gas leak alarm device or a residence alarm device having a gas leak detection function), and is 4 in the present embodiment. Bit code is used, for example, 0001 = fire 0010 = gas leak 0011 = alarm stop (fire alarm stop, gas leak alarm stop, fault alarm stop)
0100 = recovery (fire recovery, gas leak recovery, failure recovery)
0101 = Sensor failure 0110 = Low battery failure 0111 = Inspection request. Here, 0000 is used for periodic notification, for example, without event detection. The event codes of sensor failure and low battery failure are used when the automatic notification of each failure is linked.

By increasing the number of bits of the event code 54 to 5 bits and 6 bits, more event contents can be expressed. For example, recovery event codes may be divided into fire recovery, gas leak recovery, and failure recovery. Also, event codes can be appropriately assigned for various types of failures other than sensor failures and low battery failures.

  In an alarm device that detects an abnormality other than a fire, the above-described 0001 may be replaced with an abnormal event to be detected, and the type of abnormal event to be detected may be added to the above, for example. In the monitoring system of the present invention, in this way, for example, alarm devices having different types of abnormalities to be detected can be mixed in the same group.

  7 and 8 are flowcharts showing a schematic example of the monitoring process in the residential alarm 10 of FIG. In FIG. 7, when power supply from the battery power source 40 of the mortgage alarm device 10 is started, various settings including initialization, self-diagnosis, and operation mode (master mode / slave mode) settings are executed in step S <b> 1. If there is no abnormality, the process proceeds to step S2, and the fire is monitored. If there is an initialization abnormality in step S1, the fact is notified and the operation is stopped halfway, or the process of step S1 is performed again, but the illustration is omitted.

  In step S2, when the smoke detection signal output from the smoke detector 16 provided in the sensor unit 34 exceeds a predetermined fire level, the event detector 58 detects a fire and proceeds to step S3. After wirelessly transmitting an event signal (fire event signal) including a transmission source code, a group code, and an event code indicating a fire to its own identifier to another dwelling device, a voice message is sent from the speaker 56 of the notification unit 36 in step S4. A fire alarm indicating an interlocking source is output by an alarm sound such as a buzzer sound and an alarm display by, for example, lighting of the LED 22.

  Subsequently, in step S5, it is determined whether or not there is a fire recovery in which the smoke detection signal from the smoke detector 16 is lowered and the fire detection state is resolved. When the fire recovery is determined, a serial number, a transmission source code, After sending an event signal (fire recovery event signal) including an event code indicating a group code and a fire recovery to another house alarm, in step S7, interlocking by an alarm sound from the speaker 56 and an alarm display by lighting the LED 22 Stop the original fire alarm. The alarm display by the LED 22 may be turned off after a predetermined time has elapsed since the alarm sound stopped.

  Subsequently, in step S8, it is determined whether or not an alarm stop instruction operation of the alarm stop switch 20 has been detected. If the switch operation is determined, it is determined in step S9 whether or not an alarm is being issued. If it is determined in step S9 that an alarm is being issued, the process proceeds to step S10, and an event signal (alarm stop event signal) including an event code indicating a serial number, a transmission source code, a group code, and an alarm stop is sent to another residence police. In step S11, the alarm sound output indicating the link source from the speaker 56 is stopped, and the alarm display by turning on the LED 22 is turned off. The alarm display by the LED 22 may be turned off after a predetermined time has elapsed since the alarm sound stopped.

If it is determined in step S9 that an alarm is not being issued, the operation of the alarm stop switch 20 detected in step S8 is recognized as an inspection instruction operation (detected as an inspection instruction input), a predetermined inspection process is performed, and the result is obtained. Although notification is made, illustration is omitted here. Including this case, the inspection process will be described later.

  Subsequently, the process proceeds to step S12 in FIG. 8, and it is determined whether or not an effective reception detection of an event signal (fire event signal) indicating a fire transmitted or relayed from another house alarm is detected. When the effective reception of the fire event signal from another house alarm is detected, the process proceeds to step S13, where an alarm sound is output from the speaker 56 as a fire alarm indicating the interlocking destination, and an alarm display by blinking of the LED 22, for example, is performed.

  Next, in step S14, it is determined whether or not the effective reception detection of the fire recovery event signal transmitted or relayed from another resident alarm is detected, and if the effective reception of the fire recovery event signal is detected, the process proceeds to step S15 to link to The alarm display by the alarm sound output from the speaker 56 and the blinking of the LED 22 is stopped.

  Next, in step S16, it is determined whether or not an alarm stop event signal transmitted or relayed from another resident alarm is detected, and if the alarm stop event signal is received effectively, the process proceeds to step S17 and an alarm is being issued. If it is determined whether or not an alarm is being issued, the process proceeds to step S18 to stop the output of the alarm sound as the interlocking destination and also stop the alarm display.

  In step S19, it is determined whether or not a low battery failure is detected (built-in test). If a low battery failure is detected, the flow advances to step S20 to set the low battery failure flag 78 in the memory 32 and store it.

  Subsequently, the process proceeds to step S21, where it is determined whether or not a sensor failure has been detected. When a sensor failure is detected, the process proceeds to step S22, where the sensor failure flag 80 is set and stored in the memory 32.

  FIG. 9 is a flowchart showing a schematic example of the inspection request management process in the first invention of the present application by the inspection request management unit 76 provided in the processor 28 of FIG.

In FIG. 9 , after the power is turned on, in the inspection request management process, the master mode is initially set in step S31, and the time is started by starting the inspection timer 84 which is initially set to a predetermined inspection cycle, for example, 30 days. Thereafter, the process proceeds to step S32, and the event detection unit 58 determines whether or not the inspection operation is detected by the operation of the alarm stop switch 20 in the normal state (inspection instruction input detection).

  When an inspection operation is detected in step S32, the process proceeds to step S33, in which the failure flag stored in the memory 32 is referred to, and the inspection result is notified according to the stored contents. That is, as a result of the built-in test, it is determined whether or not a failure flag is set and stored in the memory 32, and when it is determined that the failure flag is not stored (no failure), for example, “pick is normal” is 1 as a confirmation sound. In addition to the fact that there is no failure, the user is informed that the sound output function such as an alarm sound of the resident alarm 10 is normal.

  At the same time, if the display for confirmation is performed, for example, by continuously driving the LED 22 for a predetermined number of pulses, the user can reconfirm that the display function is also normal.

  When it is determined that the low battery failure flag 78 is stored, the notification unit 36 outputs a low battery failure alarm, and when it is determined that the sensor failure flag 80 is stored, the notification unit 36 outputs a sensor failure alarm. . When both the low battery failure flag 78 and the sensor failure flag 80 are set and stored, the notification unit 36 sequentially outputs respective failure alarms.

  Then, it progresses to step S34, the inspection timer 84 is restarted (restarted), and the time measuring operation | movement of the inspection period 30 days is restarted from the inspection result alerting | reporting time of step S33.

  If the inspection operation is not detected in step S32, the process proceeds to step S35 to determine whether or not the current setting is the master mode. If it is determined to be the master mode, the process proceeds to step S36 and the inspection cycle 30 of the inspection timer 84 is determined. Whether or not the arrival of the manual check at the time of manual timekeeping is detected.

  If the time of the inspection cycle by the inspection timer 84 reaches 30 days without the manual inspection operation by the user in step S32, the arrival of the inspection time is detected in step S36, the process proceeds to step S37, and the inspection request event signal is transmitted. Sent to the home alarm.

Then, it progresses to step S38, LED10 of the alerting | reporting part 36 blinks, for example as an inspection request information alert | report, an inspection request display is performed, a user is informed that the manual inspection time has arrived, and prompts inspection operation.

  Subsequently, the process proceeds to step S39, where it is determined whether or not the user's inspection operation is detected by the alarm stop switch 20, and when the inspection instruction input by the user's operation is detected, the process proceeds to step S40. In accordance with the stored built-in test result, confirmation notification when there is no failure, low battery failure notification, and sensor failure notification are performed, and the inspection request display by blinking of the LED 22 is stopped in step S41.

  On the other hand, if the inspection operation is not detected in step S39, the process proceeds to step S43 to determine whether or not a predetermined waiting time has elapsed, and if it is determined that the waiting time has elapsed without detecting the inspection operation, step Proceeding to S41, the inspection request display by the blinking of the LED 22 is stopped. Subsequently, in step S43, the inspection timer 84 is restarted and the process returns to step S32.

  Here, the inspection request display performed in step S38 is performed for a long time (for example, intermittently) for the predetermined waiting time in step S42. As this waiting time, the user recognizes the arrival of the inspection time. A sufficient time, for example, 24 hours is set. Further, since the notification of the inspection request is driven by the display of the LED 22, for example, even if the arrival detection of the inspection time is determined during sleep at night, the user is not bothered as compared with the case where the notification is made by sound.

  If the slave mode is detected in step S35, or if the arrival of the manual inspection time by the inspection timer 84 is not detected in step S36, the process proceeds to step S44, and the effective reception of the inspection request event signal transmitted from another house alarm is received. The presence or absence of detection is determined.

  In step S44, when the effective reception of the inspection request event signal transmitted from the other home alarm is detected, the process proceeds to step S45, the slave mode is set, the inspection request processing based on the own inspection timer 84 is prohibited, and the like. The inspection request processing based on the inspection request event signal that is effectively received from the home alarm device is permitted. In contrast to such a slave mode, the master mode allows both inspection request processing based on its own inspection timer and inspection request processing based on effective reception of an inspection request event signal from another home alarm.

  If it is determined in step S44 that no valid reception detection of the inspection request event signal from another home alarm device operating in the master mode is detected, a manual inspection timing due to the timing of the inspection timer 84 in step S36 is reached. If it is determined whether or not a predetermined time has passed since the detection, and it has been determined that the inspection request event signal is not validly received even after the predetermined time has elapsed from the 30-day inspection cycle by the time of its own inspection timer Proceeding to S47, the master mode is set, and the processing of steps S38 to S43 is performed in the same manner as when the inspection request event signal is determined.

  By resetting the master mode in this way, rebuilding (switching of the live alarm operating in the master mode) for the failure of the live alarm operating in the master mode is automatically performed. Variations in the inspection request information notification time can be prevented. That is, in the embodiment of the first invention of the present application, a relationship in which any one of the plurality of residential alarms is set to the master mode and the remaining residential alarms are set to the slave mode is dynamically constructed.

FIG. 10 is a flowchart schematically illustrating another embodiment of the inspection request management process according to the first invention of the present application by the inspection request processing unit 76 provided in the processor 28 of FIG. When the inspection operation is not performed for the inspection request display as the inspection request information notification due to the arrival of the inspection time, the inspection cycle of the inspection timer is changed to a short inspection cycle and restarted.

  In FIG. 10, the processes of steps S51 to S62 and S65 to S69 are basically the same as the processes of steps S31 to S47 of FIG.

  As a process unique to the embodiment of FIG. 10, when a predetermined waiting time has elapsed in step S62 without determining that the inspection operation is detected in step S59, the process proceeds to step S63 and the inspection request display by blinking of the LED 22 is stopped. Then, the process proceeds to step S64, the initial inspection cycle 30 days of the inspection timer 84 initially set in step S51 is changed to a short cycle such as a half inspection cycle 15 days, and then the inspection timer 84 is restarted in step S65.

  For this reason, if the user does not perform the inspection operation for the operation request display based on the arrival of the manual inspection timing due to the passage of the inspection cycle of 30 days, the next inspection cycle is shortened to 15 days, for example, half, and the user is accelerated. You can request an inspection operation. Such an inspection cycle shortening process may be shortened to 15 days, 10 days, and 5 days, for example, every time the processes from step S59 to step S64 are repeated.

  In addition, when this process is repeated and the inspection cycle is less than a predetermined period, for example, one day, and step S63 becomes Yes again, the inspection request information may be output also by voice. .

  Such a shortening process of the inspection cycle can be similarly applied to the residential alarm of FIG. 12 described later.

FIG. 11 is a flowchart schematically illustrating another embodiment of the inspection operation management process according to the first invention of the present application by the inspection request management unit 76 provided in the processor 28 of FIG. When the inspection operation is not performed even after a predetermined waiting time has elapsed after the inspection request is displayed as the inspection request information notification when the inspection time arrives, an inspection request is indicated from the speaker 56 of the operation unit 38 as the inspection request information notification. A notification sound including a message is output.

  In FIG. 11, the processes of steps S71 to S82 and S87 to S90 are basically the same as the processes of steps S31 to S47 of FIG.

  As a process unique to the embodiment of FIG. 11, when a predetermined waiting time has elapsed in step S82 without detecting an inspection operation in step S79, the process proceeds to step S83 to indicate an inspection request from the speaker 56 of the notification unit 36. An inspection request notification sound including a message is output, for example, the message “Peep inspection timed, please press the alarm stop switch” is output.

  Subsequently, the process proceeds to step S84, where it is determined whether or not an inspection operation is detected by the alarm stop switch 20. If it is determined that there is an inspection instruction input by the user's operation, the process proceeds to step S80, and the built-in stored in the memory 32 at that time. According to the test result, notification of normality, low battery failure notification, and sensor failure notification are performed. In step S81, the inspection request display by blinking of the LED 22 or the inspection request notification sound from the speaker 56 is stopped, and in step S86. The inspection timer 84 is restarted and the process returns to step S72.

  On the other hand, if an inspection operation is not detected in step S84, it is determined in step S85 whether or not a predetermined waiting time has elapsed, and if the waiting time has elapsed, the process proceeds to step S81 to stop the inspection request display or inspection request notification sound. .

  In step S83, the display notification performed in step S78 may be stopped and the voice notification may be performed. However, in the case where the display notification is also performed in addition to the voice notification, the voice and the display notification are stopped in step S81.

  As described above, when the user does not perform the inspection operation for the operation request display based on the arrival of the manual inspection time due to the passage of the inspection cycle of 30 days, the notification sound including the message indicating the inspection operation request is output from the speaker 56. Thus, it becomes possible to notify the user who is not aware of the inspection request display of the arrival of the manual inspection time and to perform the inspection operation.

  Here, the maximum duration of the inspection request voice output in step S84 is determined by the waiting time in step S86, but during that time, the voice output is desirably performed intermittently, for example, once per hour.

  Such a voice notification process for the arrival of the manual inspection cycle can be similarly applied to the residential alarm device shown in FIGS.

  FIG. 12 is a block diagram of a main part illustrating an embodiment of the master house alarm in the second invention of the present application, and FIG. 13 is an implementation of the slave house alarm in the second invention of the present application in cooperation with the master house alarm of FIG.

When the inspection operation by the alarm stop switch 20 is detected, the inspection timer 84 is restarted after the built-in test result (normal, low battery failure or sensor failure) stored in the memory 32 is notified by the notification unit 36.

  In addition, the master inspection request processing unit 90, when detecting the inspection operation by the alarm stop switch 20 without detecting the inspection operation by the inspection timer 84, the inspection request information for requesting the inspection operation from the user in the monitoring area. Is notified by blinking of the LED 22 of the notification unit 36, for example, and an inspection request event signal is transmitted to the slave home alarm devices 10-12 to 10-16, and the own inspection timer 84 is restarted.

  On the other hand, the slave inspection request management unit 92 provided in the slave home alarm device 10-12 in FIG. 13 does not have an inspection timer and effectively receives an inspection request event signal from the master alarm device 10-11. The inspection request information for requesting the inspection operation to the user in the monitoring area is notified by, for example, blinking of the LED 22 of the notification unit 36 (in this case, for example, blinking of a pattern different from that of the master home alarm device 10-11).

  FIG. 14 shows an inspection request display as an inspection request information notification for the monitoring system of the second invention constructed by the master home alarm device 10-11 and the slave home alarm devices 10-12 to 10-16 shown in FIGS.
