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 that are not obliged to install a fire alarm system, such as group homes that support household chores for the elderly and people with intellectual disabilities, 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 total number of linked alarms linked can be increased by linking multiple groups within the warning area, and the communication frequency of the linked alarms differs depending on the group. Therefore, even if a signal from the interlocking alarm in the group and a signal from the interlocking alarm in another group arrive at the interlocking alarm of a certain group at the same time, no signal collision occurs and the signal is transmitted and received. Can be done 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, and further, for each group. 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 alarms linked to 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 equivalent to the installation of fire alarm equipment 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.

(Basic effect of the first invention)
The present invention constitutes a plurality of groups consisting of a plurality of alarms for each warning area, sets different channel frequencies for each group, and wirelessly transmits and receives signals between the alarms in the group at the same channel frequency. , When a fire is detected by one of multiple alarms and a fire alarm indicating the interlocking source is output, a fire interlocking signal is sent between other alarms in its own group and between adjacent groups. In an alarm system that sends a fire alarm to another group of alarms via a transfer device, the intergroup transfer device receives a fire-linked signal from one of its own group's alarms. If the alarm stop interlocking signal is not received within the specified waiting time, the fire interlocking signal is transmitted to the alarm device of the other group of the self to output the interlocking destination fire alarm, and the alarm stop interlocking signal is output within the waiting time. When it is received, the fire interlocking signal is not transmitted to the other group of the self, so if the alarm outputs a fire alarm and it is not a fire by on-site confirmation, the alarm stop operation is performed. Since the alarm stop interlocking signal is transmitted, for example, the first transfer adapter between groups does not immediately output the fire interlocking signal to the second transfer adapter even if it receives the fire interlocking signal, and during the predetermined waiting time. Waiting for the alarm stop interlocking signal to be received, if the alarm stop interlocking signal is received during the waiting time, the transfer signal is not output to the second adapter, and even if the alarm is activated, there is no fire. It is possible to avoid unnecessary confusion by avoiding fire alarms linked between groups.

If the alarm stop interlocking signal is not received, the fire interlocking signal is transferred between the groups in sequence with a predetermined waiting time, and the fire alarm is output in the order of the group with the highest fire risk, and the evacuation action is taken. It is possible to prevent confusion.

(Effect of inter-group transfer device equipped with two transfer adapters)
Further, the inter-group transfer device incorporates a first transfer adapter in which the first channel frequency of one group is set and a second transfer adapter in which the second channel frequency of the other group is set. 1 When the transfer adapter of one of the transfer adapter and the second transfer adapter does not receive the alarm stop interlocking signal within the predetermined waiting time when receiving the fire interlocking signal from the alarm device of its own group. Outputs a fire transfer signal to the other transfer adapter of the first transfer adapter and the second transfer adapter, and sends a fire interlocking signal from the other transfer adapter to an alarm device in its own group. Since the interlocking destination fire alarm is output and the transfer signal is not output to the other transfer adapter when the alarm stop interlocking signal is received within the waiting time, in addition to the basic effect of the first invention, An inter-group transfer device is configured by incorporating two adapters equipped with a wireless communication function with an alarm and a transfer signal input / output function, and this inter-group transfer device is used from an adjacent group such as a group boundary. By installing it in a place where fire interlocking signals can be received, in addition to fire interlocking alarms within the group when a certain group's alarm detects a fire, other by transferring the fire interlocking signal by the intergroup transfer device. Fire interlocking alarms can be output from all of the groove alarms.

In addition, the two transfer adapters incorporated as the first transfer adapter and the second transfer adapter in the inter-group transfer device are existing ones equipped with a wireless communication function with an alarm and a transfer signal input / output function. It can be realized by using the transfer adapter as it is, it can be realized easily and at low cost, and it can be promoted as a specific small-scale wireless self-fire alarm system for facilities such as private lodgings and group homes. And.

In addition, since the first transfer adapter and the second transfer adapter are incorporated in the inter-group transfer device, it is not necessary to install them separately and connect them by external wiring, and the installation location in the target facility Since the selection can be done in one place, the installation location can be easily and easily determined, and since there is no need for mutual external wiring, the installation work can be easily and easily performed.

(Basic effect of the second invention)
In another embodiment of the present invention, a plurality of groups consisting of a plurality of alarms are configured for each warning area, and different channel frequencies are set for each group to set the same channel among the alarms in the group. A signal is transmitted and received wirelessly according to the frequency, and when a fire is detected by one of multiple alarms and a fire alarm indicating the interlocking source is output, the fire interlocking signal is transmitted to the other alarms of its own group and adjacent to it. In an alarm system in which a fire alarm is output by transmitting to an alarm device of another group via an inter-group transfer device arranged between groups, the inter-group transfer device is an alarm device of one of its own groups. If the fire interlocking signal is received again within the specified waiting time when the fire interlocking signal is received from, the fire interlocking signal is transmitted to the alarm device of the other group of the self to output the interlocking destination fire alarm and wait. If the fire interlocking signal is not received again within the time, the fire interlocking signal is not transmitted to the other group of the self, so if the fire is continuously detected by the alarm, the fire is fired. Since the interlocking signal is repeatedly transmitted, the intergroup transfer device does not immediately transmit the fire interlocking signal to the other group of itself even if it receives the fire interlocking signal from one of its own groups, and has a predetermined waiting time. While waiting for the re-receipt of the fire-linked signal, if the fire-linked signal is received again during the waiting time, the fire-linked signal is sent to the other group of the self to output a fire alarm, and the alarm malfunctions. When the fire interlocking signal is transmitted, the fire interlocking signal is not received again. Therefore, the fire alarm is not issued by interlocking between groups due to the stop of the transfer, and unnecessary confusion can be avoided.

(Effect of inter-group transfer device equipped with two transfer adapters)
Further, the inter-group transfer device includes a first transfer adapter in which the first channel frequency of one of its own groups is set and a second transfer adapter in which the second channel frequency of its other group is set. When the transfer adapter of one of the first transfer adapter and the second transfer adapter is provided and receives the fire interlocking signal from the alarm device of its own group, the fire interlocking signal is received again within the predetermined waiting time. In that case, the fire transfer signal is output to the other transfer adapter of the first transfer adapter and the second transfer adapter, and the fire interlocking signal from the other transfer adapter is sent to the alarm device in the own group. The fire alarm of the interlocking destination is output by transmission, and if the fire interlocking signal is not received again within the waiting time, the transfer signal is not output to the other transfer adapter. Therefore, the basics of the second invention. In addition to the above-mentioned effect, the same effect as that of the intergroup transfer device provided with the two transfer adapters in the above-mentioned first invention can be obtained.

(Effect of transfer between group transfer devices)
Further, when the first transfer adapter receives the fire interlocking signal of the first channel frequency from another intergroup transfer device, the first transfer adapter outputs the fire transfer signal to the second transfer adapter and from the second transfer adapter. The fire interlocking signal of the second channel frequency is transmitted to the alarm device in its own group to output the interlocking destination fire alarm, and the second adapter is another intergroup transfer device different from the other intergroup transfer devices. When a fire interlocking signal of the second channel frequency is received from, a fire interlocking signal of the first channel frequency is output to the first transfer adapter, and a fire interlocking signal of the first channel frequency is output from the first transfer adapter to an alarm device in its own group. Because the interlocking destination fire alarm is output by sending to, for example, when the alarm device of the first group to which the first transfer adapter belongs detects a fire, the fire interlocking from the alarm device that detected the fire. The signal is sent via the intergroup transfer device to the alarm of the adjacent second group, followed by another intergroup transfer provided between the second group and the next third group. It is sent sequentially from the alarm device to the alarm device of the third group, but if wireless communication is possible between multiple intergroup transfer devices arranged between the groups, it is between multiple group transfer devices. By sending fire interlocking signals in sequence, it is possible to output a fire alarm with the alarm devices of all groups.

(Effect of transfer connection between 1st transfer adapter and 2nd transfer adapter)
Further, the first transfer adapter and the second transfer adapter provided in the intergroup transfer device are provided with a transfer output terminal and a transfer input terminal, and the transfer output terminal of the first transfer adapter is used as the second adapter. Since the transfer output terminal of the second transfer adapter is connected to the transfer input terminal of the first adapter by internal wiring, it is connected to the transfer input terminal of the first transfer adapter and the second transfer. As an information adapter, two existing transfer adapters equipped with a wireless communication function with an alarm and a transfer input / output function will be incorporated into the intergroup transfer device, and each input / output terminal will be connected by internal wiring. With simple work, it is possible to make an inter-group transfer device, and the device cost can be significantly reduced.

Further, since the connection between the transfer input / output terminals of the first transfer adapter and the second transfer adapter is a connection by internal wiring, the disconnection required for the connection by external wiring between the conventional repeaters is required. There is no need to provide a monitoring function, which makes it easier to manufacture and reduce costs.

(Effect of fire transfer alarm of transfer adapter)
Further, the first transfer adapter of the intergroup transfer device outputs a predetermined fire transfer alarm when the fire transfer signal is output to the second transfer adapter, and the second transfer adapter is the first transfer adapter. Since a predetermined fire transfer alarm is output when a fire transfer signal is output to, it is possible to confirm the occurrence of a fire from the output of the fire transfer alarm even with the intergroup transfer device installed in the warning area. ..

(Effect of interlocking stop control of fire alarm)
In addition, when the alarm detects a fire and detects an alarm stop operation while outputting a fire alarm indicating the interlocking source, the alarm stops the fire alarm and sends an alarm stop interlocking signal to other alarms in the group. When the interlocking destination fire alarm is stopped and the interlocking destination alarm detects an alarm stop operation, the fire alarm indicating the interlocking destination is stopped and the alarm stop interlocking signal is sent to the alarm of another interlocking destination in the group. The fire alarm of the interlocking destination is stopped by transmitting to the device, and the first transfer adapter and the second transfer adapter provided in the intergroup transfer device receive the alarm stop interlocking signal from the alarm device in its own group. In that case, the fire alarm was stopped and the alarm stop interlocking signal was not transferred. Therefore, the interlocking control to stop the fire alarm is performed within the same group and transferred to another group. By not stopping the alarm, unnecessary confusion can be avoided.

In addition, the first transfer adapter and the second transfer adapter provided in the inter-group transfer device shall stop the fire transfer alarm when the alarm stop interlocking signal is received from the alarm device in its own group. Therefore, the fire transfer alarm can be stopped appropriately in conjunction with the alarm stop operation by the alarm in the same group.

(Effect of interlocking control of fault alarm)
In addition, when a communication failure, failure, or low battery voltage is detected, the alarm outputs a failure alarm indicating the source of the failure and sends a failure interlocking signal to other alarms in the group to determine the interlocking destination. The failure alarm to be shown is output, and the first transfer adapter and the second transfer adapter provided in the intergroup transfer device indicate the link destination when the failure interlocking signal is received from the alarm device in its own group. Since the fault alarm is output and the fault interlocking signal is not transferred, the fault alarm stays in the same group and the fault alarm is not output from other groups, so that unnecessary confusion can be avoided.

(Effect of setting the same channel frequency for groups in remote alert areas)
In addition, the same channel frequency is set for multiple groups located in multiple warning areas that are far from the communication range of the alarm, so if there is no risk of interference, the same channel frequency will be used. By being able to repeatedly set multiple groups, it is possible to reduce the number of channel frequencies to be set even if the number of linked groups increases.

[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 sends an alarm stop interlocking signal to stop the fire alarm from another interlocking alarm 10 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. Since the inter-group transfer device 12-12, 12-23, 12-34 enables transmission and reception of signals to and from both interlocking alarms 10 provided in groups on adjacent floors, for example, each floor. It will be installed on the wall of the landing of the stairs connecting the stairs.

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 are provided with a transfer input terminal and a transfer output terminal, and have a transfer output terminal of the first transfer adapter 14. The transfer input terminal of the second transfer adapter 16 is connected by internal wiring, and the transfer output terminal of the second transfer adapter 16 is connected to the transfer input terminal of the first transfer adapter 14 by internal wiring. There is.

The first transfer adapter 14 incorporated in the inter-group transfer device 12-12 has a predetermined waiting time when receiving a fire interlocking signal having a channel frequency f1 from an interlocking alarm 10 belonging to its own group G1. If the alarm stop interlocking signal is not received during that time, the fire transfer signal is output to the second transfer adapter 16, while if the alarm stop interlocking signal is received during the predetermined waiting time, the second transfer is performed. The transfer is stopped without outputting the fire transfer signal to the information adapter 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 waits for a predetermined time when it receives a fire interlocking signal having a channel frequency f2 from an interlocking alarm 10 belonging to its own group G2. If the alarm stop interlocking signal is not received during the time, the fire transfer signal is output to the first transfer adapter 14, while if the alarm stop interlocking signal is received during the predetermined waiting time, the first is 1 The transfer is stopped without outputting the fire transfer signal to the transfer 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.

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.

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 a fire interlocking signal having a channel frequency f1 from another interlocking alarm in the communication unit 20, an alarm sound indicating the interlocking destination from the speaker 28, for example, "Woo another fire". The alarm sound "Please check that the alarm has been activated" is repeatedly output, and at the same time, the operation indicator 26 is controlled to blink, for example, to output a fire alarm indicating the interlocking destination.

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 the transmission to the alarm device of.

Further, the interlocking alarm control unit 18 performs a communication test, battery voltage drop monitoring, and circuit failure monitoring, and when a communication error, battery voltage drop, or circuit failure is detected, a predetermined failure alarm is given from the speaker 28. It outputs a sound and blinks the operation indicator 26 to output a failure alarm, and further controls the communication unit 20 to transmit a failure interlocking signal from the communication unit 20 to another interlocking alarm device using the channel frequency f1. ..

[Functional configuration of inter-group transfer device]
FIG. 3 is a block diagram showing the functional configuration of the inter-group transfer device, and the inter-group transfer device 12-12 installed between the group G1 on the 1st floor and the group G2 on the 2nd floor in FIG. 1 is taken as an example. The same applies to the other intergroup transfer devices 12-23, 12-34.

As shown in FIG. 3, the intergroup transfer device 12-12 is provided with a first transfer adapter 14 and a second transfer adapter 16 in one device housing. The first transfer adapter 14 is set to the channel frequency f1 of the group G1, and the second transfer adapter 16 is set to the channel frequency f2 of the group G2. , Basically the same.

The first transfer adapter 14 includes an adapter control unit 32, a communication unit 34 to which the antenna 36 is connected, an operation indicator 42, a speaker 44, a test switch 46, and a transfer output unit 38 connected to the transfer output terminal 38a. It is composed of a transfer input unit 40 connected to the transfer input terminal 40a, and operates with a battery power supply (not shown). The second transfer adapter 16 has the same configuration.

The transfer input terminal 40 a and the transfer output terminal 38 a may be configured as a connector structure that grips when wiring is inserted. Further, the antenna 36 may be built in the transfer adapter housing.

The inter-group transfer device has a panel door that can be opened and closed on the front of the box-shaped device housing that opens in the front, and by opening the panel door, the first transfer adapter and the second transfer adapter can be operated. It has a visible structure.

The transfer output terminal 38a of the first transfer adapter 14 is connected to the transfer input terminal 40a of the second transfer adapter 16 by the internal wiring 48, and the transfer input terminal 40a of the first transfer adapter 14 is connected to the transfer input terminal 40a of the first transfer adapter 14. The internal wiring 50 from the transfer output terminal 38a of the second transfer adapter 16 is connected.

The transfer output unit 38 outputs a non-voltage contact signal by connecting to the transfer input unit 40 on the second transfer adapter 16 side by the internal wiring 48. That is, the transfer output unit 38 of the second transfer adapter 16 applies a power supply voltage to one of the internal wirings 48 via a pull-up resistor, and the transfer output unit 38 of the first transfer adapter 14 has a power supply voltage. A non-voltage a contact that is turned on by the operation of the relay is connected between the internal wiring 48.

When the first transfer adapter 14 outputs a transfer signal, the non-voltage contact of the transfer output unit 38 is turned on by the operation of the relay to pass a current through the internal wiring 48, and the transfer input of the second transfer adapter 16. The voltage between the internal wirings seen from the unit 40 drops to substantially zero volt, and the voltage drop of the internal wiring 48 is detected to detect the input of the fire signal. The transfer output unit 38 of the second transfer adapter 16 and the transfer input unit 40 of the first transfer adapter 14 also input and output non-contact voltage signals in the same manner.

The adapter control unit 32 is composed of a computer circuit including a CPU, a memory, and various input / output ports.

The communication unit 34 is the same as the communication unit 20 provided in the interlocking alarm device 10 of FIG. 2, sets the channel frequency f1 assigned to the group G1 based on the initial settings, etc., and is an interlocking type belonging to the same group G1. Signals can be transmitted and received wirelessly to and from the alarm device 10, and in the case of Japan, for example, STD-30 (low power security system radio) known as a standard for specific low power radio stations in the 400 MHz band. It has a configuration that conforms to the station radio equipment standard).

The operation indicator 42 displays a fire transfer alarm, a failure alarm, or the like by blinking, lighting, blinking, or the like of the LED based on the instruction of the adapter control unit 32. The speaker 44 outputs a voice message or an alarm sound by voice synthesis based on the instruction of the adapter control unit 32. The test switch 46 performs operations such as alarm stop, communication test, transfer stop, and transfer stop release.

The control function of the adapter control unit 32 of the first transfer adapter 14 is realized by executing a program, and has the following control functions.

When the adapter control unit 32 of the first transfer adapter 14 receives the fire interlocking signal of the first channel frequency f1 from the interlocking alarm 10 of its own group G1, as the transfer control operation of the first embodiment, If the alarm stop interlocking signal is not received during the predetermined waiting time, the transfer output unit 38 is operated to output the fire transfer signal to the second transfer adapter 16 when the predetermined waiting time has elapsed. Control is performed, while if an alarm stop interlocking signal is received during a predetermined waiting time, the transfer output unit 38 is not activated and the fire transfer signal is not output to the second transfer adapter. Take control.

The adapter control unit 32 of the second transfer adapter 16 that has detected the input of the fire transfer signal from the first transfer adapter 14 instructs the communication unit 34 to set the fire interlocking signal of the channel frequency f2 in the group G2. Is transmitted to the interlocking alarm device 10 in its own group G2 to output a fire alarm indicating the interlocking destination.

Further, when the adapter control unit 32 of the first transfer adapter 14 detects the input of the fire transfer signal from the second transfer adapter 16, it instructs the communication unit 34 to transmit the fire interlocking signal of the channel frequency f1. Control is performed to output a fire alarm indicating the interlocking destination by transmitting to the interlocking alarm 10 in the group G1.

Further, when the adapter control unit 32 of the first transfer adapter 14 receives a fire interlocking signal from the interlocking alarm 10 in its own group G1 and does not receive the alarm stop interlocking signal during a predetermined waiting time. Repeatedly outputs an alarm sound "Woo Woo fire alarm has been activated, please check" from the speaker 44 when the predetermined waiting time has elapsed, and at the same time blinks the operation indicator 42, for example, to move the fire. Controls to output an alarm. The fire transfer alarm by the first transfer adapter 14 may not output an alarm sound, but may only display the fire transfer alarm by the operation indicator lamp 42.

Further, when the adapter control unit 32 of the first transfer adapter 14 receives an alarm stop interlocking signal from the interlocking alarm 10 in its own group G1 during a fire transfer alarm or a failure alarm, the fire transfer is performed. Controls to stop alarms and fault alarms.

Further, the adapter control unit 32 of the first transfer adapter 14 receives a failure interlocking signal transmitted by detecting a communication failure, a failure, or a decrease in the battery voltage by the interlocking alarm 10 in its own group G1. In this case, a voice message indicating the content of the failure is output from the speaker 44, and a failure alarm is output by repeating the operation of blinking the operation indicator 42 a predetermined number of times at predetermined time intervals.

The control function of the adapter control unit 32 is the same as that of the adapter control unit 32 of the second transfer adapter 16.

Further, the first transfer adapter 14 that has received the fire alarm interlocking signal from the interlocking alarm 10 in its own group G1 receives the fire alarm interlocking signal when the alarm stop interlocking signal is not received during the predetermined waiting time. The alarm and the fire transfer signal are output to the second transfer adapter 16, but the second transfer adapter 16 to which the fire transfer signal is input fire-interlocks with the interlocking alarm 10 in its own group G2. Although the signal is transmitted, the alarm operation may not be performed.

Such an alarm operation of the first transfer adapter 14 is the same when the second transfer adapter 16 receives a fire alarm interlocking signal from an interlocking alarm device in its own group G2.

If the first transfer adapter 14 and the second transfer adapter 16 give an alarm at the same time, the voices are mixed and it becomes difficult to hear, but it becomes difficult to hear because the alarm operation of the transfer adapter on the side where the fire transfer signal is input is not performed. Avoid that.

Further, the second transfer adapter 16 may receive a fire interlocking signal having a channel frequency f2 set in the group G2 transmitted from the adjacent intergroup transfer devices 12-23 shown in FIG. In this case, since the adapter control unit 32 of the second transfer adapter 16 does not receive the alarm stop interlocking signal from the adjacent intergroup transfer devices 12-23, the transfer is transferred after a predetermined waiting time has elapsed. The output unit 38 is operated to control the output of the fire transfer signal to the first transfer adapter 14.

When the adapter control unit 32 of the first transfer adapter 14 detects the input of the transfer signal from the second transfer adapter 16, it instructs the communication unit 34 to interlock with the fire of the channel frequency f1 set in the group G1. It controls to send a signal to the interlocking alarm device 10 in its own group G1 to output an interlocking destination fire alarm.

In this way, the transfer of the fire interlocking signal via the intergroup transfer device 12-12, 12-23, 12-34 does not include communication via the interlocking alarm 10 of each group during that time. For example, when a fire is detected in a shorter communication time, the fire alarm of the group G4 farthest from the group G1 can be linked.

[Control operation of transfer adapter]
FIG. 4 is a flowchart showing a transfer control operation according to the first embodiment of the transfer adapter device incorporated in the intergroup transfer device, and is a first diagram incorporated in the intergroup transfer device 12-12 of FIG. Taking the control of the transfer adapter 14 as an example, it will be as follows.

As shown in FIG. 4, the adapter control unit 32 of the first transfer adapter 14 has a channel frequency f1 of the group G1 assigned to itself by a predetermined registration operation or the like in the initial setting of step S1 accompanying the turning on of the battery power. Is set.

Subsequently, when the adapter control unit 32 determines in step S2 that the fire interlocking signal transmitted from the interlocking alarm device 10 in its own group G1 has been received, the adapter control unit 32 proceeds to step S3 and determines whether or not the alarm stop interlocking signal has been received. If the alarm stop interlocking signal is not received, the process proceeds to step S4, and it is determined whether or not the predetermined waiting time has elapsed.

Here, when a user who knows the fire alarm from the interlocking alarm 10 that has been activated by detecting a fire goes to the installation location and confirms that there is no fire, the test switch 30 performs an alarm stop operation. An alarm stop interlocking signal is transmitted. Therefore, when the adapter control unit 32 determines the reception of the alarm stop interlocking signal in step S3, it proceeds to step S5 and stops the transfer, so that the fire signal is not output to the second transfer adapter 16 and the step S2 is performed. return.

On the other hand, if the reception of the alarm stop interlocking signal is not determined in step S3 until the elapse of the predetermined waiting time is determined in step S4, the process proceeds from step S4 to step S6 to the second transfer adapter 16. The fire transfer signal is output, and subsequently, in step S7, the fire transfer alarm is output by the alarm sound from the speaker 44 and the operation of the operation indicator lamp 42.

Further, when the adapter control unit 32 determines the input of the fire transfer signal from the second transfer adapter 16 by the transfer input unit 40 in step S8, the adapter control unit 32 proceeds to step S9 and instructs the communication unit 34 to instruct its own group G1. A fire interlocking signal is transmitted to the inside, and subsequently, in step S10, a fire transfer alarm is output by the alarm sound from the speaker 44 and the operation of the operation indicator lamp 42.

Further, when the adapter control unit 32 determines in step S11 that the alarm stop interlocking signal has been received from the interlocking alarm device 10 of its own group via the communication unit 34, the adapter control unit 32 proceeds to step S12 and proceeds to step S12, during a fire transfer alarm or a failure alarm. If it is determined that the fire is inside, the fire transfer alarm is stopped even if the process proceeds to step S13.

Further, when the adapter control unit 32 determines in step S14 that the failure interlocking signal has been received from the interlocking alarm device 10 of its own group G1 via the communication unit 34, the adapter control unit 32 proceeds to step S15 and proceeds to step S15 to display the alarm sound and the operation from the speaker 44. A failure alarm is output by the operation of the light 42.

Here, the intergroup transfer device 12-12 that has received the fire interlocking signal from the interlocking alarm 10 in the group G1 has the second transfer adapter 16 after the elapse of a predetermined waiting time from the first transfer adapter 14. A fire interlocking signal is output to, and a fire interlocking signal is transmitted from the second transfer adapter 16 to the interlocking alarm device 10 of the group G2 to output a fire alarm. Similarly, the intergroup transfer device 12 At -23, 12-34, inter-group interlocking transfer is performed via a predetermined waiting time.

In this way, fire alarms can be output to each group unit via a predetermined waiting time in descending order of fire risk, such as group G1 to group G2, G3, G4 where a fire occurred. By evacuating from a place with a high risk of fire, it is possible to avoid confusion due to congestion of the evacuation route and enable quick and safe evacuation guidance.

[Second Embodiment of Transfer Adapter and Transfer Control Operation]
As the transfer control operation of the second embodiment by the adapter control unit 32 provided in the first transfer adapter 14 and the second transfer adapter 16 of the intergroup transfer device 12 shown in FIG. 3, for example, the first transfer. Taking the adapter control unit 32 of the adapter 14 as an example, when the fire interlocking signal of the first channel frequency f1 is received from the interlocking alarm 10 of its own group G1, the fire interlocking signal is emitted during a predetermined waiting time. When it is received again, when the predetermined waiting time has elapsed, the transfer output unit 38 is operated to control the output of the fire transfer signal to the second transfer adapter 16, while the predetermined waiting time is reached. If the fire interlocking signal is not re-received during that time, the transfer output unit 38 is not operated, and control is performed to stop the transfer without outputting the fire transfer signal to the second transfer adapter 16.

FIG. 5 is a flowchart showing a transfer control operation according to the second embodiment of the transfer adapter device incorporated in the intergroup transfer device, and is a first diagram incorporated in the intergroup transfer device 12-12 of FIG. Taking the control of the transfer adapter 14 as an example, it will be as follows.

As shown in FIG. 5, the adapter control unit 32 of the first transfer adapter 14 has a channel frequency f1 of the group G1 assigned to itself by a predetermined registration operation or the like in the initial setting of step S21 accompanying the turning on of the battery power. Is set.

Subsequently, when the adapter control unit 32 determines in step S22 that the fire interlocking signal transmitted from the interlocking alarm 10 in its own group G1 has been received, the adapter control unit 32 proceeds to step S23 and determines whether or not a predetermined waiting time has elapsed. If the waiting time has not elapsed, the process proceeds to step S24, and it is determined whether or not the fire interlocking signal has been re-received.

Here, when the interlocking alarm 10 detects a fire due to a malfunction and transmits a fire interlocking signal, the adapter control unit 32 waits in a predetermined manner in step S23 because the fire interlocking signal is not transmitted. When the passage of time is determined, the process proceeds to step S25, and the transfer is stopped, so that the fire signal is not output to the second transfer adapter 16 and the process returns to step S22.

On the other hand, if it is determined in step S24 that the alarm stop interlocking signal is received again until the elapse of the predetermined waiting time is determined in step S23, the process proceeds from step S24 to step S26, and the second transfer adapter 16 A fire transfer signal is output to, and subsequently, in step S27, a fire transfer alarm is output by the alarm sound from the speaker 44 and the operation of the operation indicator lamp 42.

Since the subsequent control operations in steps S28 to S35 are the same as in steps S8 to S15 in FIG. 4, the description thereof will be omitted.

Further, a group G2 having the same channel frequency f2 as the 2F is assigned to the 6F.

Here, the interlocking alarm 10 installed in each group has a limit in its communicable distance. For example, the radio wave from the interlocking alarm 10 installed on the 1st floor is the interlocking type installed on the 5th floor. It does not reach the alarm 10.

Even if the interlocking alarm 10 with the same channel frequency f1 is installed in the 1st floor and the 5th floor, which are warning areas separated from the communicable area of the interlocking alarm 10, signals are sent to each other. Since it cannot send and receive, there is no problem of interference. This point is the same between the 2nd floor and the 6th floor.

Therefore, in the present embodiment, the same channel frequency f1 is set with the 1F and 5F separated beyond the communicable area of the interlocking alarm 10 as the group G1, and similarly, the same channel with the 2F and 6F as the group G2. The frequency f2 is set, and even if the number of interlocking groups increases, the number of channel frequencies to be set can be reduced without causing interference.
