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 is output from the alarm unit, Since it is possible to monitor and warn a fire with a single residence guard without requiring a dedicated receiving facility, it is easy to install and inexpensive, and has become widespread due to the obligatory installation in ordinary houses.

  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 interlocking house alarm system, when a fire is detected by the house alarm, the interlocking house alarm detecting the fire is a fire alarm sound including a message and an alarm sound, for example, “Woo Woo Fire Alarm On the other hand, the alarm device linked to, for example, output a fire alarm sound indicating the linked site, such as `` Please check if another fire alarm was activated by Woo Woo ''. I have to.

  Further, in recent years, as a result of efforts to reduce the power consumption of residential alarms, a long battery life of, for example, 10 years or more is guaranteed, and no battery replacement is necessary during that period. When battery life (remaining power capacity) decreases when battery life (remaining power supply capacity) decreases after long-term use, a low battery failure alarm is detected and a low battery failure alarm (battery warning warning) is output to encourage battery replacement. Yes.

  In addition, when a failure such as a sensor unit, a detection circuit, a sound notification circuit failure, a sensitivity abnormality due to contamination, a battery abnormality, or the like is detected, a failure alarm is output to prompt a response.

  Such failure monitoring is automatically executed in the background as a built-in test, and when a failure is detected, failure information is stored in the memory. For this reason, when a failure is detected, a failure alarm is output at predetermined intervals, for example, based on the failure information in the memory.

In addition, when the user performs an inspection switch operation in the normal monitoring state, a fault alarm is output if fault information is stored in the memory, and information indicating normality is output if no fault alarm is stored in the memory. The

Japanese Patent No. 3895646 Utility Model Registration No. 3154579

  As described above, in the case of a conventional house alarm device, when a failure is detected, failure information and the like are output and notified as a failure alarm. There are various types of information that the user wants to inform the user to properly maintain and manage the home alarm, for example, the elapsed period from the start of operation and the predicted period until the battery runs out.

  In this way, when it is desired to inform the user of necessary information from the home guard, for example, if it is an elapsed period from the start of the operation, for example, when the arrival of a predetermined operation period is detected, it is “the third year” “5 years” It is possible to output information such as “the eyes” as a voice message.

  However, the method of unilaterally outputting information from the home alarm based on the arrival of a period, etc., is not transmitted if the user is absent when outputting information, and such information during sleeping such as at night Outputting the sound may disturb the sleep. Of course, it is also possible to provide a human sensor to output information when the presence of a person is detected, or to generate or acquire clock information to prohibit information output in the night time zone. However, it is not practical because it causes an increase in the cost of housing police.

  Such a problem applies not only to the interlocked house alarm but also to the stand-alone house alarm that does not have an interlocking function.

SUMMARY OF THE INVENTION An object of the present invention is to provide an alarm device and a monitoring system capable of asking a user for a confirmation information requesting operation and reliably transmitting confirmation information.

The present invention provides an alarm device for observing an environmental change to detect and notify an abnormality in a monitoring area.
An operation unit for performing a predetermined operation including a confirmation request operation;
To notify confirmation request information requesting confirmation request operation when detecting the arrival of regular confirmation request timing including transitional period from the operation start, confirmation for notifying the confirmation information when detecting a confirmation request operation by the operation unit A request processing unit;
Is provided.

In another form of the present invention, in an alarm device that observes environmental changes and detects abnormalities in the monitoring area, and reports in cooperation with other alarm devices,
An operation unit for performing a predetermined operation including a confirmation request operation;
Transmits the interlock signal indicating the confirmation request to the other alarm devices causes informed the confirmation request information requesting confirmation request operation when detecting the arrival of regular confirmation request timing including transitional period from the operation start, whereas, A confirmation request processing unit that informs confirmation request information for requesting a confirmation request operation when receiving an interlock signal indicating a confirmation request from another alarm device, and further informs confirmation information when a confirmation request operation by the operation unit is detected; ,
Is provided.

Here, if the confirmation request processing unit does not detect the confirmation request operation by the operation unit even after a predetermined waiting time has elapsed after notifying the confirmation request information, the period until the next confirmation request is set to a short predetermined period. Change to detect the arrival of the next confirmation request.

The present invention is a monitoring system provided with a plurality of alarm devices that detect changes in the monitoring area by observing environmental changes and notify each other in cooperation with each other.
For each of the multiple alarms,
An operation unit for performing a predetermined operation including a confirmation request operation;
Transmits the interlock signal indicating the confirmation request to the other alarm devices causes informed the confirmation request information requesting confirmation request operation when detecting the arrival of regular confirmation request timing including transitional period from the operation start, whereas, A confirmation request processing unit that informs confirmation request information for requesting a confirmation request operation when receiving an interlock signal indicating a confirmation request from another alarm device, and further informs confirmation information when a confirmation request operation by the operation unit is detected; ,
Is provided.

Here, if the confirmation request processing unit does not detect the confirmation request operation by the operation unit even after a predetermined waiting time has elapsed after notifying the confirmation request information, the period until the next confirmation request is set to a short predetermined period. Change to detect the arrival of the next confirmation request.

  According to the monitoring system of the present invention, the confirmation request information for requesting the confirmation request operation to the user when the arrival of a periodic or non-periodic confirmation request timing is detected in the alarm device constituting the information is displayed and notified, for example. Information (confirmation information) to be confirmed by the user who has noticed this notification performing confirmation request operation can be output by, for example, pronunciation, and the user who has performed the confirmation request operation can directly recognize the confirmation information.

  For this reason, confirmation information is not output to the user when the user is absent or at an inappropriate time such as when sleeping, etc., and when there is a user, that is, the user operates a confirmation request against the alarm device. Confirmation information can be surely notified.

  Moreover, in the alarm device of the interlock type monitoring system in which the alarm devices are linked by communication, when the arrival of the confirmation request timing is detected in any of the plurality of alarm devices, the confirmation request is indicated to the other alarm devices. The interlocking signal is transmitted to notify the confirmation request information. When the user who notices the notification performs the confirmation request operation, the confirmation information is output. Similarly, the confirmation information is sent to the user who has performed the confirmation request operation. It can be recognized directly.

  If the confirmation request operation is not detected even after a predetermined waiting time has elapsed for the notification of the confirmation request information, the periodic or non-periodic period until the next confirmation request is shortened from the previous time. The period until the confirmation request information arrives and the confirmation request information is output early and the confirmation request information is output should not be too long, and a long period of time will elapse without confirming the information to be confirmed by the user. Can be avoided.

  Here, shortening the periodic period until the confirmation request from the previous time means that the confirmation request is triggered when the first period elapses, the confirmation request is made, and there is no operation. This means that the confirmation request timing comes again after the second period shorter than the period of time elapses, the confirmation request is made, and a timeout occurs after a predetermined time because there is no operation, and so on. It should be noted that a limit is set for shortening the period, and if there is an operation, the period returns to the periodic confirmation request cycle after the first time elapses.

Also, to shorten the non-periodic period up to the confirmation request from the previous time, the confirmation request time has arrived and the confirmation request is made, because there is no operation, it times out after a predetermined time, and the confirmation request is made again after the first predetermined time. Time out after a predetermined time because there is no operation, a confirmation request is made again after a second predetermined time shorter than the first predetermined time, time out after a predetermined time because there is no operation, etc. It means to repeat. In this case as well, a limit is set for shortening the period, and if there is an operation, the process returns to an irregular check request cycle from that point.

  FIG. 1 is an explanatory view showing an example of an installation state of a monitoring system using an interlocked house guard according to the present invention for a house. In the example of FIG. 1, a wireless interlocking type home alarm device that detects a fire in each monitoring area of a kitchen, a living room, a child's room, a main bedroom, and a staircase provided in the house 24 and alarms in conjunction. (House fire alarms) 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 interlocking signals to each other, and monitors whether or not a fire has occurred in each corresponding monitoring area of each 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 resident guard 10-1 issues a report, the resident guard 10-1 functions as an interlocking source, performs an alarm operation as the interlocking source, and other housing policers 10-2 to 10- serving as interlocking destinations. Send fire-linked signal to 6 When other fire alarms 10-2 to 10-6 have received the fire-linked signal from the linked house-guard 10-1 effectively, they perform an alarm operation as an interlocking destination by an alarm sound and an alarm display. .

  Here, when the group code included in the received interlocking signal matches the group code registered in its own memory and the signal content is normally recognized, the home alarm device 10 has effectively received this interlocking signal. I try to detect that. Further, the interlocking signal transmitted from the home alarm device 10 includes a source code using, for example, a serial number as identification information indicating the source home alarm device. This source code is also stored in each memory in the same manner as the group code. Furthermore, the resident guard 10 that has effectively received the interlocking signal relays the interlocking signal as necessary.

  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.

  FIG. 2 is an explanatory view showing the appearance of a wireless interlocking smoke type house alarm according to the present invention. FIG. 2 (A) shows a front view and FIG. 2 (B) 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.

  A plurality of acoustic holes 18 are 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.

  The alarm stop switch 20 is configured such that when a switch cover formed of a translucent member is pressed, an internal push switch (not shown) is pressed. An LED 22 for displaying an alarm or the like is disposed near the push switch inside the switch cover.

  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 fire which generate | occur | produces with a fire and detects the fire of a monitoring area is taken as an example. In addition to this, there are residential alarms equipped with temperature detectors such as thermistors that detect fires based on the heat generated by fires, and other alarms that detect other environmental changes due to fires. Alarms to be detected, various alarms for detecting intruders, earthquakes, and other abnormalities, and alarms formed by combining these alarms are also included in the scope of the present invention. The alarm 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 the residential alarm according to the present invention. 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 in the monitoring system of this embodiment.

  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 an interlocking signal 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.

  In the memory 32, a serial number 48, which is a serial number indicating the generation order or transmission order of the interlocking signal, a transmission source code 50 using, for example, a serial number or the like serving as residential alarm identification information for identifying each residential alarm, The group code | symbol 52 for comprising the interlocking | linkage group which performs an interlocking | linkage alarm with each residence guard 10 installed in the house like 1 is stored.

  The sensor unit 34 is provided with a smoke detector 16 that detects smoke based on the scattered light type smoke detection principle and outputs a detection signal corresponding to the smoke density. That is, the sensor unit 34 observes the smoke generation status as an environmental change in the monitoring area due to an abnormality (fire).

  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, confirmation information, etc. based on various data held by itself. A voice synthesizer and an amplifier for driving the speaker 56 are not shown. The LED 22 displays other things including abnormalities such as fire, faults, and confirmation request displays by blinking, blinking, and lighting. The illustration of the drive circuit of the LED 22 is also omitted.

  The operation unit 38 is provided with an alarm stop switch 20, and the alarm stop switch 20 also functions as an inspection switch for instructing self-inspection of the function of the home alarm device 10. For example, when the alarm stop switch 20 is operated during a series of fire alarm outputs (including an output pause period for each intermittent cycle when the fire alarm is output intermittently), the fire alarm is stopped and in a normal state When the alarm stop switch 20 is operated, 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. Further, the alarm stop switch 20 functions as a confirmation request switch when the notification unit 36 notifies the user of confirmation request information for a confirmation request operation.

  The battery power source 40 uses, for example, a lithium battery or an alkaline battery having a predetermined number of cells, and supplies power to necessary parts. As the battery capacity, for example, a battery life of 10 years is guaranteed by reducing the power consumption of the entire circuit unit including the wireless communication unit 30 in the residence guard 10-1.

  The processor 28 is provided with functions of a monitoring processing unit 60 and a confirmation request processing 62 as functions realized by executing the program.

  The monitoring processing unit 60 has a fire based on a detection signal output from the smoke detector 16 provided in the sensor unit 34, a warning stop instruction input by the operation unit 38, a check instruction input, a confirmation request instruction input. The detection signal output from the smoke detection unit 16 provided in the sensor unit 34 is lowered and the fire detection state is resolved, whether there is a fire recovery, sensor failure or low battery failure due to the detection signal from the failure detection unit 66, etc. Detect an event. In addition, the monitoring processing unit 60 includes the presence / absence of effective reception of the interlocking signal obtained as a result of decoding the interlocking signal received from the other mortgage alarm devices 10-2 to 10-6 via the receiving unit (the antenna 31 and the receiving circuit 44). The interlocking contents are detected.

  In addition, when the monitoring processing unit 60 detects a fire based on the smoke detection signal of the smoke detecting unit 16 provided in the sensor unit 34, an alarm sound indicating the interlocking source from the speaker 56 to the notification unit 36, for example, “Woo Woo Fire. "Please check" and repeat the output of the voice message, control to turn on the LED 22 and display the alarm indicating the interlocking source, and further send the fire interlock signal via the transmission circuit 42 to the antenna 31 To the other residence guards 10-2 to 10-6. The transmission circuit 42 and the antenna 31 are collectively referred to as a transmission unit.

  In addition, when the monitoring processing unit 60 detects that a fire-linked signal is effectively received from any of the other residential alarm devices 10-2 to 10-6 via the receiving circuit 44 of the wireless communication unit 30, a notification unit An alarm sound indicating the interlocking destination is repeatedly output from the 36 speakers 56, for example, a sound message such as “Woooo another fire alarm has been activated”, and simultaneously flashing the LED 22 to indicate the interlocking destination. To do.

  Further, when the monitoring processing unit 60 detects the operation of the alarm stop switch 20 during the output of the fire alarm sound indicating the interlock source, the monitoring processing unit 60 controls the notification unit 36 to fire alarm by the voice message from the speaker 56 and the alarm display of the LED 22. The output of is stopped. In addition, when the effective reception of the alarm stop interlocking signal from any of the other residential alarm devices 10-2 to 10-6 is detected during the output of the fire alarm sound indicating the interlock source, the fire alarm is not stopped and interlocked Try to understand the origin. That is, in the case of the interlock source, the alarm is stopped only by the alarm stop operation of the alarm stop switch provided in its own operation unit 38.

  Further, the monitoring processing unit 60 operates the own alarm stop switch 20 or outputs an alarm stop interlock signal from any of the other residential alarm devices 10-2 to 10-6 while outputting an alarm sound indicating the interlock destination. Is detected, the notification 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.

  The monitoring processing unit 60 is provided with a low battery failure monitoring function in which the power supply voltage of the battery power supply 40 is less than a predetermined level, and is automatically executed in the background as a built-in test.

  Specifically, the low battery fault monitoring is a built-in that reads a battery voltage supplied from the battery power supply 40 at a predetermined measurement time interval, for example, an interval of 4 hours, through a voltage monitoring circuit (not shown) and compares it with a predetermined threshold voltage. When a test is performed, a low battery failure is preliminarily determined when the threshold voltage is less than this threshold voltage, and when the low battery failure preliminary determination continues for a predetermined number of times, the low battery failure is determined (determined) and detected. The battery failure flag is set and updated and stored in the memory 32.

  The monitoring processing unit 60 is provided with a sensor failure monitoring function for monitoring a failure of the sensor unit 34, and is automatically executed in the background as a built-in test. Specifically, the sensor failure monitoring is performed by reading a smoke detection signal output from the smoke detector 16 of the sensor unit 34 at a predetermined measurement time interval, for example, at an interval of 1 second, and holding the smoke detection signal in the memory 32. For example, every 10 minutes, an average value of the detection data for the last 10 minutes held in the memory 32 is obtained, and this average value is a predetermined reference level (a detection signal level in a state where no smoke flows into the smoke detector 16). If it falls below the zero point level), it is determined that the output of the sensor unit 34 is faulty as being in an output stop state, etc., and a sensor fault flag is set and updated and stored in the memory 32.

  When the monitoring processing unit 60 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, the low battery failure flag or the sensor failure flag is set and stored in the memory 32. When it is detected that the low battery failure alarm or the sensor failure alarm is output from the notification unit 36, the low battery failure interlocking signal or the sensor failure interlocking signal is output to the other housing alarm devices 10-2 to 10-. 6 to output a low battery failure alarm or a sensor failure alarm indicating the failure interlock destination.

  Further, the monitoring processing unit 60 detects the fire based on the detection signal output from the smoke detector 16, the alarm stop input or the inspection instruction input by the operation unit 38, and the detection signal output from the smoke detector 16 is lowered to cause the fire detection state. When a self-event such as a low battery failure or a sensor failure is detected, such as a fire recovery to be resolved, an interlock signal indicating the detected event content is transmitted via the transmission circuit 42 of the wireless communication unit 30 and the antenna 31. To the home alarm devices 10-2 to 10-6. The monitoring processing unit 60 relays and transmits the interlocking signal that has been effectively received from the other residential alarm devices 10-2 to 10-6 as necessary.

  The main purpose of relay transmission is, for example, when the communication distance is long or when there is an obstacle in the communication path, for example, the interlock signal directly arrives from the Dwelling Unit 10-1 to the Dwelling Unit 10-3. When there is no communication environment, the resident guard 10-6 that has received the interlock signal from the resident guard 10-1 relays this to cause the resident guard 10-3 to receive the interlock signal. This is to supplement communication. Such communication complementation by the relay function is useful when three or more home alarm devices are installed in one interlocking group, for example, the house 24.

  In addition, the monitoring processing unit 60 receives and decodes the interlocking signals from the other residential alarm devices 10-2 to 10-6 via the antenna 31 and the receiving circuit 44 of the wireless communication unit 30. In addition, the monitoring processing unit 60 has normally received the interlocking signal from the other residential alarm devices 10-2 to 10-6 with the transmission of the interlocking signal to the other residential alarm devices 10-2 to 10-6. It is monitored whether or not an acknowledgment signal (hereinafter, referred to as “ACK signal”) indicating that is effectively received.

  In the case where an ACK signal that is not received is detected among the other resident alarms 10, the resident alarm 10-1 transmits an interlocking signal including a relay request code to the other resident alarms that have received the ACK signal. Then, the interlock signal including the relay request code is relay-transmitted from the home police device that has received the interlock signal including the relay request code to the other home police device that has not yet responded to the AKC signal. Other housing alarm devices that have not received an AKC signal that has received a relay request with a relay request validly return an ACK signal for the effective reception of the interlocking signal including the relay request code. Via relay transmission) at the home guard 10-1 as the interlocking source. Accordingly, if there is a residence guard that does not receive the ACK signal, it is determined as a communication failure or the like, and a predetermined notification process, a linkage process, a linkage process described later, and the like are performed.

  The confirmation request processing unit 62 notifies the user of confirmation request information for a confirmation request operation when detecting the arrival of a predetermined periodic or non-periodic confirmation request timing for predetermined confirmation information. If the confirmation request interlocking signal is transmitted to the other home guards 10-2 to 10-6 and the confirmation required interlocking signal is received from the other home guards 10-2 to 10-6, the confirmation is made to the user. The confirmation request information for requesting the requested operation is notified, and further, the confirmation information is notified when an effective confirmation request operation by the alarm stop switch 20 of the operation unit 38 is detected after the confirmation request timing arrives.

  The notification of confirmation request information for requesting a confirmation request operation from the user by the confirmation request processing unit 62 is performed by turning on, blinking, or blinking the LED 22 provided in the notification unit 36. Although it is possible to notify the confirmation request information by outputting a notification sound from the speaker 56 of the notification unit 36, it is possible to disturb the sleep when the notification sound is emitted during sleep, but it is preferable to display only the LED 22, It is not excluded to notify the sound generation by using a low volume output or a long cycle intermittent output. For example, a notification sound such as “beep” from the speaker 56 is intermittently output at a volume that does not disturb sleep.

  In addition, since the notification of the confirmation request information prompts the user to perform a confirmation request operation, the operation for displaying and driving the LED 22 for about 10 seconds, for example, every predetermined hour, for example, every 24 hours is repeated. Thus, the period during which the LED 22 is displayed and the confirmation request notification is continued means a waiting time until the user performs a confirmation operation (operation reception waiting time).

  Also, when the confirmation request processing unit 62 notifies the confirmation request information by the display drive of the LED 22, the confirmation request operation by the alarm stop switch 20 of the operation unit 38 is not detected even if a predetermined waiting time, for example, 24 hours elapses. Timeout and return to the normal state from the operation acceptance standby state. Then, the period until the next confirmation request is changed to a predetermined period shorter than the previous time, and the arrival of the next confirmation request time is monitored. As a result, even if the confirmation information is not informed to the user due to absence or the like, the user is prompted to confirm the information again after a short period of time, and the period during which the user does not confirm the information to be confirmed is shortened as much as possible. .

  In this embodiment, the confirmation information for requesting confirmation from the user includes, for example, the following.

(1) Elapsed period from the start of operation (regular)
The period is calculated every 1 year from the start of operation, and the elapsed period information such as “It will be the 1st year”, “It will be the 2nd year”, ... “It will be the 10th year” is notified. . (Regularly)

(2) Expected period until the battery runs out (non-periodic)
When the prediction period from the start of the operation to the battery exhaustion reaches a predetermined period, for example, one year, the battery exhaustion prediction information such as “battery replacement time is about another year” is notified. After that, for example, every time a predetermined number of months elapses, battery exhaustion prediction information such as “battery replacement time is about 6 months later” and “battery replacement time is about 3 months later” is notified.

  The remaining operable period until the low battery failure or the battery runs out may be calculated based on the periodic voltage detection result of the voltage monitoring circuit, and the remaining operable period may be notified based on the calculated result. Also, instead of such a calculation process, a plurality of voltage thresholds are provided and compared with the detected voltage, and the operation is performed based on a table in which the operable remaining period (corresponding audio data ID) is associated with each threshold interval. It is also possible to notify the possible remaining period. For example, if the detected voltage is in the range of X volts to Y volts, the remaining operable period is Z years from the table, and the corresponding voice data is notified.

(3) Installation guidance information (non-periodic)
To start using the home alarm, for example, when the power is turned on by pulling out the insulating seal that is sandwiched between the battery and the terminal and taking out the end part to the outside, the alarm stop switch Installation guidance information such as “Please install it at the height of the wall” is notified according to the confirmation operation.

(4) Event history information (non-periodic)
When an event occurs or when sensitivity correction of the sensor unit is performed, it is stored as circumstance occurrence history information and notified to the user. Sensor failure, low battery failure, failure and other failure information may be included in this event occurrence history information.

(5) Environmental change information other than abnormalities (non-periodic)
When the sensor unit 36 is provided with a temperature detection element, it observes environmental changes other than fires, for example, changes in room temperature, and informs the user of environmental change information such as “the environmental temperature exceeds the usable range”. Inform. In the case of the environmental temperature based on the temperature change, it is performed based on a relatively long-term moving average or the like so as not to be mistaken as a temperature increase caused by a fire. Of course, a sensor provided with a temperature detection unit in addition to the sensor unit can be similarly implemented.

(6) Cleaning guidance information (regular)
When the smoke detection unit 16 is provided in the sensor unit 36, cleaning guidance information such as “Check the smoke inlet and remove dust” every time a predetermined period, for example, 3 years has elapsed from the start of operation, is given to the user. Inform.

  The confirmation information for requesting confirmation from the user can be set as appropriate information to be transmitted to the user as necessary. In addition, as necessary additional information for each of the above information, appropriate information such as a manufacturer name, a store name, a contact address, a model name, a manufacturing number, a lot number, and the like as a corresponding inquiry destination may be notified together.

  FIG. 4 is an explanatory diagram schematically showing the format of the interlocking signal used for the interlocking alarm in this embodiment. In FIG. 4, the interlocking signal 46 includes a serial number 48, a transmission source code 50, a group code 52, and an event code 54. It should be noted that both the link source transmission source code and its own transmission source code as the relay transmission source are added to the link transmission signal for relay transmission.

Here, the event code 54 is a code representing the content of an event such as a fire. In the present embodiment, a 4-bit code is used. For example, 0001 = fire 0010 = ACK
0011 = Alarm stop 0100 = Recovery 0101 = Sensor failure 0110 = Low battery failure 0111 = Confirmation request.

  Although the relay request code described above is omitted here, it can be added to the event code by increasing the number of bits. Alternatively, the relay request code can be assigned to “1111”, for example. In addition, both the ID indicating the transmission source (linkage source) residence alarm device and the ID of the residence alarm device relaying are added to the linkage signal to be relayed. Further, an ID for designating a transmission destination may be added. Further, for example, “0000” may be assigned for periodic communication confirmation. Of course, more event codes can be assigned by increasing the number of bits.

  FIG. 5 is a flowchart showing a schematic example of the monitoring process of the residential alarm shown in FIG. In FIG. 5, when power supply from the battery power source 40 of the home guard 10 is started, various settings including initialization, self-diagnosis, and transmission / reception mode setting are executed in step S <b> 1. Proceeding to S22, it is determined whether or not a fire is detected. If there is an initialization abnormality in step S1, the fact is notified and the operation is stopped, or the process of step S1 is performed again (in this case as well, the initialization abnormality is continuously detected a predetermined number of times). When this happens, the fact is notified and the operation is stopped), and 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, a fire is detected, and the process proceeds to step S3, where the fire-linked signal is wirelessly transmitted to other residential alarms. While transmitting, a fire alarm indicating an interlocking source is output from the speaker 56 of the notification unit 36 by an alarm sound by a voice message or the like and an alarm display by, for example, lighting of the LED 22 (alarm operation as an interlocking source).

  Subsequently, in step S4, it is determined whether or not a fire recovery is detected in which the smoke detection signal from the smoke detector 16 is lowered and the fire detection state is resolved. When a fire recovery is detected, a fire recovery interlock signal is transmitted in step S5. The fire alarm indicating the interlocking source by the alarm sound from the speaker 56 and the lighting of the LED 22 is stopped. The alarm display by the LED 22 may be turned off after a predetermined time has elapsed since the alarm sound stopped.

  Subsequently, at step S6, it is determined whether or not an alarm stop instruction operation of the alarm stop switch 20 has been detected. When an alarm stop instruction operation is detected, the process proceeds to step S7, where an alarm stop interlock signal is transmitted to the other house alarms, and the speaker The alarm sound output indicating the interlocking source from 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.

  Then, it progresses to step S8 and it is discriminate | determined the detection presence / absence of the fire interlocking | linkage signal effective reception transmitted or relay-transmitted from the other residence police. When the effective reception of the fire interlocking signal from another house alarm is detected, the process proceeds to step S9, where an alarm sound is output from the speaker 56 as a fire alarm indicating the interlocking destination, for example, an alarm display by blinking of the LED 22 is performed ( Alarm action as a linkage destination).

  Next, in step S10, the presence / absence of the effective reception of the fire recovery interlock signal transmitted or relayed from another resident alarm is detected. When the effective reception of the fire recovery interlock signal is detected, the process proceeds to step S11 and the interlock destination The alarm display by the alarm sound output from the speaker 56 and the blinking of the LED 22 is stopped as an alarm.

  Next, in step S12, it is determined whether or not an alarm stop interlocking signal effective reception transmitted or relayed from another resident alarm is detected, and when the alarm stop interlocking signal effective reception is detected, the process proceeds to step S13 to interlock with The alarm sound output is stopped and the alarm display is also stopped. Then, it progresses to step S14 and a confirmation request process is performed.

  Here, in the flowchart of FIG. 5, processing when an event signal indicating a low battery failure or a sensor failure is received from another residential alarm is omitted, but a low battery failure or a sensor failure is received from another residential alarm. When the effective reception of the event signal indicating is detected, a low battery failure alarm or a sensor failure alarm indicating the link destination is performed with an alarm sound and an alarm display.

  FIG. 6 is a flowchart showing an example of the confirmation request processing in step S14 of FIG. 5 as an example. In FIG. 6, the confirmation request process is performed in step S21, for example, by determining whether or not confirmation request timing has been detected based on a predetermined period for the confirmation information shown in (1) to (6) above. When the request time arrival detection is discriminated, the process proceeds to step S22, and a confirmation request interlocking signal is transmitted to the other residential alarm devices 10-2 to 10-6.

  Subsequently, in step S23, a confirmation request for requesting the user for a confirmation request operation is notified, for example, by blinking the LED 22 provided in the notification unit 36 for a predetermined time. Here, intermittent flashing may be used instead of continuous flashing. Subsequently, in step S24, it is determined whether or not a predetermined waiting time, for example, the passage of 24 hours has been detected. If the waiting time has not elapsed, the process proceeds to step S25, and the alarm stop switch 20 provided in the operation unit 38 is operated. Whether or not the confirmation request operation is detected is determined.

  If the confirmation request operation of the user is detected in step S25 before detecting the elapse of the waiting time in step S24, the process proceeds to step S26, and the corresponding confirmation information, for example, the elapsed period from the start of the operation is “third year”. Is output from the speaker 56 of the operation unit 36.

  On the other hand, if the elapse of the waiting time is detected in step S24 without detecting the confirmation operation request in step S25, the process proceeds to step S28, and the period until the next confirmation request time is shortened as necessary. Although illustration is omitted, a limit is set for this shortening. For example, in the case of shortening continuously by repeating the confirmation request process, when the predetermined number of times continues, step S28 is passed, and more Do not shorten.

  For example, in the case of confirmation information that is to be notified regularly every year, such as an elapsed period from the start of operation, the period until the next confirmation request time is shortened from one year to, for example, six months. Confirmation information when such a period is shortened is, for example, when the next period of 1 year is shortened to 6 months without a confirmation request operation being detected for the elapsed period from the start of operation, which is “3rd year” , The confirmation information such as “It will be three and a half years” is notified. Even if the period is shortened, the confirmation information may not be changed, and “third year” may be notified. The period shortening process in step S28 is not necessarily performed, and the arrival of the next confirmation request time may be detected without shortening the period.

  When the process of step S26 or S28 is completed, the process proceeds to step S27, and counting of a period until the next confirmation request is started.

  Subsequently, in step S29, it is determined whether or not the valid reception of the confirmation request interlocking signal from the other residential police devices 10-2 to 10-6 is detected, and if the valid reception of the confirmation request interlocking signal is detected, the process proceeds to step S30. For example, the confirmation request for requesting the confirmation request operation from the user is notified by, for example, blinking the LED 22 provided in the notification unit 36 for a predetermined time. Instead of continuous flashing, intermittent light emission with a reduced duty ratio may be used. Subsequently, in step S31, it is determined whether or not a predetermined waiting time has been detected. If the waiting time has not been detected, the process proceeds to step S32, and a confirmation request operation is performed by operating the alarm stop switch 20 provided in the operation unit 38. Whether or not is detected.

  If the user's confirmation request operation is detected in step S32 before detecting the elapse of the waiting time in step S31, the process proceeds to step S33, the corresponding confirmation information is output from the speaker 56 of the operation unit 36, and then the process proceeds to step S34. Then, the shortening is reset, and the counting of the period until the next confirmation request (the period set first) is started.

  On the other hand, if the elapse of the waiting time is detected in step S31 without detecting the confirmation operation request in step S32, the process returns to the main routine of FIG.

  FIG. 7 is a block diagram showing a configuration of a main part of a home alarm according to another embodiment of the present invention, which is intended for a so-called stand-alone home alarm that does not perform radio interlocking. 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. 3 is different from the embodiment of FIG. 3 in that the configuration related to the wireless communication function (that is, the interlocking function) is deleted. Moreover, although the transfer part 130 is provided in this embodiment, this can also be added to embodiment of FIG. Accordingly, the monitoring processing unit 160 of the processor 128 does not have the interlock processing function by the monitoring processing unit 60 provided in the processor 28 of FIG. In addition, about the functional configuration substantially the same as FIG. 3, the same code | symbol as what was used for FIG. 3 is attached | subjected.

  When the monitoring processor 160 detects a fire based on the detection signal from the smoke detector 16, the transfer unit 130 outputs a transfer signal as a no-voltage contact open / close signal to other devices according to the instruction of the monitoring processor 160. To do.

  FIG. 8 is a flowchart showing a schematic example of the monitoring process of the residential alarm shown in FIG. In FIG. 8, when the power supply by the battery power source 40 of the home guard 100 is started, initialization, reading of various settings including self-diagnosis, etc. are executed in step S41. The presence or absence of detection is detected. If there is an initialization abnormality in step S41, the fact is notified and the operation is stopped, or the processing of step S41 is performed again (in this case as well, the initialization abnormality is continuously detected a predetermined number of times). When this happens, the fact is notified and the operation is stopped), and the illustration is omitted.

  In step S42, when the smoke detection signal output from the smoke detector 16 provided in the sensor unit 34 exceeds a predetermined fire level, a fire is detected, and the process proceeds to step S43, and a voice message or the like is sent from the speaker 56 of the notification unit 36. A fire alarm is output by an alarm sound and an alarm display by turning on the LED 22, for example.

  Subsequently, in step S44, it is determined whether or not there is a fire recovery detection in which the smoke detection signal from the smoke detector 16 is reduced and the fire detection state is resolved. When a fire recovery is detected, an alarm sound from the speaker 56 is detected in step S45. And fire alarm by lighting of LED22 is stopped. 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 S46, it is determined whether or not an alarm stop instruction operation of the alarm stop switch 20 has been detected. When an alarm stop instruction operation is detected, the process proceeds to step S7, the alarm sound output from the speaker 56 is stopped, and an alarm by lighting the LED 22 is performed. Turn off the display. The alarm display by the LED 22 may be turned off after a predetermined time has elapsed since the alarm sound stopped. Then, it progresses to step S48 and a confirmation request process is performed.

  FIG. 9 is a flowchart showing details of the confirmation request process in step S48 of FIG. In FIG. 9, in the confirmation request process, in step S51, for example, whether or not a confirmation request has arrived based on a period set in advance for the confirmation information shown in (1) to (6) above is detected. When the arrival of time is detected, the process proceeds to step S52, where a confirmation request for requesting the user for a confirmation request operation is notified by, for example, blinking the LED 122 provided in the notification unit 136 for a predetermined time. Instead of continuous flashing, intermittent light emission with a reduced duty ratio may be used.

  Subsequently, in step S53, it is determined whether or not a predetermined waiting time, for example, 24 hours has been detected. If the waiting time has not been detected, the process proceeds to step S54, and the alarm stop switch 120 provided in the operation unit 138 is operated. Whether or not the confirmation request operation is detected is determined.

  If the user's confirmation request operation is detected in step S54 before detecting the elapse of the waiting time in step S53, the process proceeds to step S55, and the corresponding confirmation information, for example, the elapsed period from the start of the operation is “3rd year”. Is output from the speaker 156 of the operation unit 136.

  On the other hand, if the elapse of the waiting time is detected in step S53 without detecting the confirmation operation request in step S54, the process proceeds to step S57, and the period until the next confirmation request time is shortened as necessary. The details of the shortening method are the same as those described in FIG. 3 in the processing of FIG. 6 in the embodiment.

  When the processing of step S55 or S57 is completed, the process proceeds to step S56, the shortening is reset, the count of the period until the next confirmation request (initially set period) is started, and the process returns to the main routine of FIG.
