Description

The present invention relates to an alarm system in which a plurality of alarm devices that detect and give an alarm by detecting a fire are installed by grouping to give an interlocking alarm.

Conventionally, alarm devices that detect and give an alarm in a house or the like have become widespread. Of these, residential fire alarms are called residential alarms. For example, such a resident fire alarm operates on a battery power source, and has a sensor unit for detecting a fire and an alarm unit for warning a fire in the resident fire alarm, and fires based on the detection signal of the sensor unit. When it is detected, a fire alarm sound is output from the alarm unit, and unlike the so-called automatic fire alarm system, it does not require a receiver, etc., and the fire alarm can be monitored and alarmed by itself, so installation is easy. It is also inexpensive and has become widespread as it becomes mandatory to install it in ordinary houses.

In addition, when a fire alarm sound is output by any of the smoke detectors by mutually performing wireless communication between multiple smoke detectors, the other smoke detectors also work together to output a fire alarm sound. An alarm system using a type of housing police device has also been put into practical use and has become widespread.

In addition, for specific small-scale facilities with a floor area of less than 300 square meters, such as group homes that support the household affairs of the elderly and people with intellectual disabilities, who are not obliged to install a fire alarm system, automatic for specific small-scale facilities. Fire alarm system has been introduced. The automatic fire alarm system for specified small-scale facilities consists of a sensor that has a sensor unit that detects a fire and an alarm unit that warns of a fire. When it is detected, all the detectors in the facility will issue an alarm to notify the entire facility of the fire.

Hereinafter, the detector used for the wireless interlocking residential police device and the automatic fire alarm system for a specific small-scale facility will be referred to as an interlocking alarm device.

In such an interlocking alarm system, when a fire is detected by the interlocking alarm, the interlocking alarm that detected the fire is, for example, "Woo Woo, please check that the fire alarm has been activated." While outputting a fire alarm sound such as, and turning on the alarm display LED, on the other hand, the interlocking destination alarm output a fire alarm sound such as "Woo, another fire alarm has been activated. Please check" and an alarm. The display LED is blinking.

However, in such a conventional wireless interlocking alarm system, when one interlocking alarm receives a radio signal from another interlocking alarm, a plurality of wireless signals using the same communication frequency are used. May arrive at the same time and cause a signal collision, and the frequency of signal collisions increases as the number of interlocking alarms installed in the warning area increases, so the interlocking alarms that can be installed in one warning area The number is limited.

In order to solve this problem, when forming a group consisting of multiple interlocking alarms, the maximum number of interlocking alarms restricted so that the frequency of signal collisions does not increase is set, and the multiple groups formed in this way. We have proposed an alarm system in which repeaters are arranged and interlocked between them, and the communication frequencies used for each group are different (Patent Document 1).

In this group-linked warning system, the number of linked alarms can be increased by linking multiple groups within the warning area, and if the groups are different, the communication frequency of the linked alarms will change. Because they are different, even if the signal from the interlocking alarm in the group and the signal from the interlocking alarm in another group arrive at the interlocking alarm of one group at the same time, no signal collision occurs and the signal Transmission and reception can be performed reliably.

This problem of signal collision is the same in a system that does not distinguish between the master unit and the slave unit of the interlocking alarm when using a wireless signal, and in a parent-child system in which multiple slave units are arranged for the master unit. Yes, in the case of the parent-child method, for example, the master unit sequentially calls and processes the slave units using the individual IDs of the slave units, but when the number of slave units increases, the total number of retries due to signal collision increases. Communication takes time. Therefore, in order to reduce the frequency of signal collisions with the master unit, the number of slave units is limited to a predetermined maximum number or less to form a group, and the master unit of each group is provided with a relay function to work together. It is an alarm system with different communication frequencies used for.

For this reason, the warning system, which is larger than ordinary houses and consists of ordinary wirelessly interlocking residential alarms, cannot cover the entire area due to the limitation of the maximum number of alarms, but in recent years, it is known as a private lodging that is expected to be used. By installing an alarm system that links groups to facilities that operate simple lodgings under the Ryokan Business Law and specific small-scale facilities, it is necessary to have the number of linked alarms for the entire facility while avoiding the problem of signal collision. The number has been increased to a sufficient number, and it is possible to provide a fire monitoring function that is substantially equivalent to installing a fire alarm system at low cost.

However, in such a conventional alarm system that performs group interlocking, in order to interlock between a plurality of groups, a repeater is arranged for each group and connected by a transfer signal line, which is a wireless interlocking type. Commercially available interlocking alarms can be used, but it is necessary to add a new repeater for interlocking between groups, and it is legal to install fire alarm equipment in private lodging facilities and group homes. Compared to compulsory facilities such as buildings and condominiums, the number is small and the number of production is limited, so the cost is high and it is a bottleneck for widespread use.

On the other hand, in an alarm system using a wireless interlocking type interlocking alarm, a transfer adapter that receives a fire interlocking signal from the interlocking alarm and outputs a transfer signal is commercially available, for example. When a fire alarm device is connected to the transfer adapter via a transfer signal line and a fire interlocking signal is received by the transfer adapter from the interlocking alarm, the fire transfer signal is output to the fire alarm device and automatic notification is made to 119. It is possible to make it happen.

In addition, the transfer adapter is equipped with a transfer input terminal to enable test transmission, and as a result, in addition to the wireless communication function with the interlocking alarm, it is possible to input and output transfer signals. Since it is an existing product, there are few cost issues.

On the other hand, in the case of an alarm system that interlocks between groups, in the unlikely event that a fire occurs or a non-fire alarm is output, an interlocking alarm within the group is used to investigate the cause of the fire and the non-fire factors. It is conceivable to provide a function to store log information indicating how the device operated, and to read and use the log information stored in the interlocking alarm by an external device such as a tester as needed. ..

However, the interlocking alarm that interlocks between groups is installed in a place that cannot be accessed when there are users such as guest rooms, and it is necessary to collect the log information stored in the interlocking alarm. Has the problem of time and effort.

The present invention provides an alarm system that makes it possible to easily and at low cost realize a system configuration in which a fire alarm is interlocked between a plurality of groups consisting of a plurality of interlocking alarms by using an existing transfer adapter. The purpose is.

Another object of the present invention is to provide an alarm system that can easily and easily collect and use log information such as fire detection without entering the place where an alarm is installed.

[Overview of alarm system]
FIG. 1 is an explanatory diagram showing an embodiment of an alarm system arranged in a building having a hierarchical structure.
As shown in FIG. 1, the warning system of the present embodiment is installed in a four-story building 11 such as a private lodging facility, and the warning area is a floor-based warning area on the 1st to 4th floors. For example, five wirelessly interlocking interlocking alarms 10 that function as alarms are installed in each of the warning areas.

Here, the five interlocking alarms 10 installed on the 1st floor to the 4th floor constitute groups G1, G2, G3, and G4 as shown on the left side of the building 11, and the groups G1, G2, and G3. , G4 are assigned different channel frequencies f1, f2, f3, f4, and the interlocking alarms 10 of each group G1 to G4 use the channel frequencies f1 to f4 assigned to their own group. And send and receive signals.

The interlocking alarms 10 provided in the groups G1 to G4 output a fire alarm indicating the interlocking source when a fire is detected, and transmit a fire interlocking signal to other interlocking alarms 10 in their own group. And output a fire alarm indicating the interlocking destination. Further, when the fire detection continues, the interlocking alarm 10 repeatedly transmits a fire interlocking signal at predetermined intervals.

Further, when the interlocking alarm 10 detects a fire and outputs a fire alarm, and the user confirms that there is no fire at the installation location of the interlocking alarm 10, the alarm stop operation is performed. However, when this alarm stop operation is performed, the interlocking alarm 10 stops the fire alarm and transmits an alarm stop interlocking signal to stop the fire alarm from other interlocking alarms in its own group.

An inter-group transfer device 12-12, 12-23, 12-34 is installed between the groups G1 to G4 corresponding to the caution area for each floor of the building 11. The inter-group transfer device 12-12, 12-23, 12-34 is capable of transmitting and receiving signals to and from both interlocking alarms 10 provided in groups on adjacent floors, and thus is restricted from entering and exiting. It will be a common space without any space, for example, it will be installed on the wall of the landing of the stairs connecting each floor.

The inter-group transfer device 12-12, 12-23, 12-34 incorporates a first transfer adapter 14 and a second transfer adapter 16.

For example, taking the intergroup transfer device 12-12 installed between the group G1 on the first floor and the group G2 on the second floor as an example, the first transfer adapter 14 is an interlocking alarm device of the group G1 on the 1st floor. The same channel frequency f1 as 10 is set, and various signals including a fire interlocking signal are transmitted and received to and from the interlocking alarm 10 of the group G1 installed on the first floor.

Further, the second transfer adapter 16 has the same channel frequency f2 as the interlocking alarm 10 of the group G2 on the 2nd floor, and is connected to the interlocking alarm 10 of the group G2 installed on the second floor. Sends and receives various signals including fire interlocking signals.

The first transfer adapter 14 and the second transfer adapter 16 incorporated in the intergroup transfer device 12-12 include a transfer transmission unit, and the transfer transmission unit and the second transfer adapter of the first transfer adapter 14. The transfer transmission unit of 16 is connected by an internal transmission path, and various signals and data can be transmitted and received between the first transfer adapter 14 and the second transfer adapter 16.

The first transfer adapter 14 incorporated in the inter-group transfer device 12-12 receives a fire interlocking signal having a channel frequency f1 from an interlocking alarm 10 belonging to its own group G1 and receives a second transfer adapter. A fire alarm signal is output to 16.

The second transfer adapter 16 to which the fire transfer signal from the first transfer adapter 14 is input transmits the fire interlocking signal of the channel frequency f2 to the interlocking alarm 10 in its own group G2 to set the interlocking destination. Output the fire alarm shown.

Further, the second transfer adapter 16 incorporated in the inter-group transfer device 12-12 receives the fire interlocking signal of the channel frequency f2 from the interlocking alarm 10 belonging to its own group G2, and receives the first transfer. A fire transfer signal is output to the alarm adapter 14.

The first transfer adapter 14 to which the fire transfer signal from the second transfer adapter 16 is input transmits the fire interlocking signal of the channel frequency f1 to the interlocking alarm 10 in its own group G1 to set the interlocking destination. Output the fire alarm shown.

Further, the inter-group information transfer device 12-12 is provided with a function of a log collecting unit, and a fire interlocking signal, an alarm stop interlocking signal, a fire recovery interlocking signal, and a failure interlocking signal are transmitted from the interlocking alarm device 10 of its own group. When a predetermined interlocking signal including the log information is received, log information is generated and stored in the memory. Specifically, each of the first transfer adapter 14 and the second transfer adapter 16 provided in the intergroup transfer device 12-12 is provided with a function of a log collection unit.

Therefore, the log collection unit of the first transfer adapter 14 generates log information when receiving various interlocking signals from the interlocking alarm 10 of its own group G1 and stores it in the memory, and also transfers the second. When the log collecting unit of the information adapter 16 receives various interlocking signals from the interlocking alarm 10 of its own group G2, the log collecting unit generates log information and stores it in the memory.

Further, the log information collected by the first transfer adapter 14 and the second transfer adapter 16 can be collected by reading and outputting by the tester 60 functioning as an external device. When the log collection unit of the first transfer adapter 14 receives a log output instruction signal specifying the address of the intergroup transfer device 12-12 from the tester 60 by wireless communication connection using the channel frequency f1. The log information of the interlocking alarm 10 of the group G1 stored in its own memory is read and transmitted, and at the same time, the log of the interlocking alarm 10 of the group G2 stored by instructing the second transfer adapter 16 is instructed. The information is read and transmitted, and the log information collected by the received second transfer adapter 16 is transmitted to the tester 60.

Further, the log collection unit of the second transfer adapter 16 is instructed to output a log by designating the address of the intergroup transfer device 12-12 by wireless communication connection using the channel frequency f2 from the tester 60 functioning as an external device. When a signal is received, the log information of the interlocking alarm device 10 of the group G2 stored in its own memory is read and transmitted, and the first transfer adapter 14 is instructed to interlock the stored group G1. The log information of the type alarm device 10 is read and transmitted, and the received log information collected by the first transfer adapter 14 is transmitted to the test device 60.

Here, when the tester 60 transmits, for example, a log output instruction signal using the channel frequency f2, the second transfer adapter 16 of the intergroup transfer device 12-12 and the first of the intergroup transfer devices 12-23. Although it is received by both transfer adapters 14, the log output instruction signal specifies the address of the intergroup transfer device 12-12, so that the first transfer adapter 14 of the intergroup transfer device 12-23 is used. The log information is not transmitted from, but the log information is transmitted only from the second transfer adapter 16 of the intergroup transfer device 12-12 that has received the address designation.

Further, the tester 60 may be a dedicated device, or a general-purpose device provided with an application for outputting log information on a smartphone, a mobile terminal, or the like may be used.

The functions of the first transfer adapter 14 and the second transfer adapter 16 are the same for the intergroup transfer devices 12-23 and 12-34, except that the channel frequencies used are different.

Therefore, the channel frequency f2 of the group G2 is set in the first transfer adapter 14 of the intergroup transfer device 12-23, and the channel frequency f3 of the group G3 is set in the second transfer adapter 16.

Further, the channel frequency f3 of the group G3 is set in the first transfer adapter 14 of the intergroup transfer device 12-34, and the channel frequency f4 of the group G4 is set in the second transfer adapter 16.

Here, the communication route of the fire interlocking signal between the groups G1 and G4 is, for example, when a fire is detected by the interlocking alarm 10 of the group G1, the interlocking alarm 10 of the group G1 and the intergroup. Transfer device 12-12, group G2 interlocking alarm 10, intergroup transfer device 12-23, group G3 interlocking alarm 10, intergroup transfer device 12-34 and group G4 interlocking alarm The first route to be 10, and the interlocking alarm 10 of the group G1 are sent to the intergroup transfer devices 12-12, 12-23, 12-34, and the intergroup transfer devices 12-12, 12-23, There is a second route sent from 12-34 to the interlocking alarms 10 of each group G2, G3, G4.

As shown in FIG. 1, when the intergroup transfer devices 12-12, 12-23, 12-34 are arranged at the landing of the stairs, etc., and the adjacent devices can transmit and receive wireless signals, the first Communication is performed by two routes. On the other hand, when the intergroup transfer devices 12-12, 12-23, and 12-34 are far from the communicable area, the communication follows the first route. Further, it is assumed that the first route and the second route are mixed communication.

[Functional configuration of interlocking alarm]
FIG. 2 is a block diagram showing a functional configuration of an interlocking alarm. As shown in FIG. 2, the interlocking alarm 10 is composed of an interlocking alarm control unit 18, a communication unit 20 having an antenna 22, a sensor unit 24, an operation indicator lamp 26, a speaker 28, and a test switch 30. It operates on a battery power supply (not shown).

The interlocking alarm control unit 18 is composed of a computer circuit including a CPU, a memory, and various input / output ports.

The communication unit 20 sets, for example, one of the four channel frequencies f1, f2, f3, and f4 in the 400 MHz band, for example, the channel frequency f1, based on the instruction from the interlocking alarm control unit 18 based on the initial settings and the like. , It is possible to wirelessly transmit and receive signals to and from other interlocking alarms 10 belonging to the same group.

In the case of Japan, the communication unit 20 has a configuration compliant with STD-30 (low power security system radio station radio equipment standard), which is known as a standard for specific low power radio stations in the 400 MHz band, for example. .. Of course, the communication unit 20 will have the contents conforming to the standard of the assigned radio station in the area for the place other than Japan.

The sensor unit 24 is provided with a smoke detection unit so as to detect a fire when the smoke due to the fire reaches a predetermined concentration. In addition to the smoke detection unit, a temperature detection element such as a thermistor that detects the temperature due to a fire or various elements that detect changes in other physical phenomena due to a fire may be provided.

The operation indicator lamp 26 displays an abnormality such as a fire by blinking, lighting, blinking, or the like of the LED based on the instruction of the interlocking alarm control unit 18. Further, a two-color LED or two LEDs having different display colors may be provided, and the display colors may be different between the display of the interlocking source and the display of the interlocking destination.

The speaker 28 outputs a voice message or an alarm sound by voice synthesis based on the instruction of the interlocking alarm control unit 18.

The test switch 30 also functions as an inspection switch, and can input an alarm stop instruction only when the alarm sound of the speaker 28 and the alarm display of the operation indicator lamp 26 are being performed, and the test switch 30 is a test switch in a normal state. When 30 is operated, a function check is performed and the result is notified.

The control function of the interlocking alarm control unit 18 is realized by executing a program, and has the following control functions.

When the interlocking alarm control unit 18 detects a fire from the smoke detection unit provided in the sensor unit 24 based on the smoke detection signal, an alarm sound indicating the interlocking source is activated from the speaker 28, for example, "Woo fire alarm has been activated." "Please check" is repeatedly output, and the operation indicator lamp 26 is turned on, for example, to output an alarm indicating the interlocking source.

Further, the interlocking alarm control unit 18 controls to transmit a fire interlocking signal from the communication unit 20 to another interlocking alarm using the channel frequency f1 when a fire is detected. Further, if the fire detection state continues after the fire is detected, the interlocking alarm control unit 18 transmits a fire interlocking signal from the communication unit 20 from the communication unit 20 at predetermined intervals to another interlocking type using the channel frequency f1. Controls to repeatedly transmit to the alarm.

Further, when the interlocking alarm control unit 18 receives the fire interlocking signal of the channel frequency f1 from the other interlocking alarm 10 in the communication unit 20, the alarm sound indicating the interlocking destination from the speaker 28, for example, "Woo-separate". It controls to repeatedly output an alarm sound that says "Please check that the fire alarm has been activated" and at the same time output a fire alarm that indicates the interlocking destination by blinking the operation indicator 26, for example.

Further, when the interlocking alarm control unit 18 detects the alarm stop operation of the test switch 30 during the output of the fire alarm or the failure alarm, the interlocking alarm control unit 18 sends an alarm stop interlocking signal for stopping the alarm sound from the speaker 28 to other members in the group. Controls transmission to the interlocking alarm device 10.

Further, when the interlocking alarm control unit 18 detects fire recovery from the signal of the sensor unit 24 after the fire is detected, the interlocking alarm control unit 18 stops the fire alarm indicating the interlocking destination and sends the fire recovery interlocking signal from the communication unit 20 to the channel frequency f1. It is used to control the fire alarm to be transmitted to another interlocking alarm 10 to stop the interlocking destination.

Further, the interlocking alarm control unit 18 performs a communication test, battery exhaustion monitoring due to a decrease in battery voltage, and circuit failure monitoring, and when a communication error, battery exhaustion, or circuit failure is detected, a predetermined speaker 28 is used.
