Description

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

Conventionally, alarms that detect and warn fires in houses and 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 alarm system, and fires based on the detection signal of the sensor unit. When a fire alarm is detected, a fire alarm sound is output from the alarm unit, and unlike the so-called automatic fire alarm system, fire monitoring and alarm notification can be performed by the Smoke Detector alone without the need for a receiver, etc., so installation is easy. It is also inexpensive and has become widespread due to the mandatory installation in ordinary houses.

In addition, when a fire alarm sound is output by any of the smoke detectors by 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 smoke detector 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 fire alarm equipment, 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 specific small-scale facilities is composed of a sensor that detects a fire and an alarm that warns of a fire, and the detectors are wirelessly linked to each other to cause a fire. When it is detected, all the detectors in the facility issue a report 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 fire alarm has been activated. Please check." While outputting a fire alarm sound such as, and turning on the alarm display LED, the interlocking destination alarm output a fire alarm sound such as "Woo, another fire alarm has been activated. Please check." 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 restricted.

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

In this group-linked alarm system, the total number of alarms linked can be increased by linking multiple groups within the warning area, and different groups have different alarm communication frequencies, so a certain group. Even if a signal from an alarm device in the group and a signal from an alarm device in another group arrive at the alarm device at the same time, signal collision does not occur and the signal can be reliably transmitted and received.

The problem of this signal collision is the same in a system that does not distinguish between the master unit and the slave unit of the alarm when using a wireless signal, and in a parent-child system in which a plurality of slave units are arranged with respect to the master unit. 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 number of retries due to signal collision increases, resulting in overall communication. take time. Therefore, in order to reduce the frequency of signal collisions with the master unit, the slave units are limited to a predetermined maximum number or less to form a group, and the master units of each group are interlocked with each other by providing a relay function. 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 police, cannot cover the entire area due to the limitation of the maximum number of warning devices, but in recent years, it is known as a private lodging that is expected to be used. By installing a group-linked warning system at facilities that operate simple lodgings under the Ryokan Business Law and specific small-scale facilities, it is necessary to increase the number of alarms linked to the entire facility while avoiding the problem of signal collision. By increasing the number to a sufficient number, 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 warning system that performs group interlocking, in order to interlock between a plurality of groups, repeaters are arranged for each group and connected by a transponder signal line, which is a wireless interlocking type. Commercially available interlocking alarms can be used, but a repeater that functions as an intergroup transfer device that links groups must be newly added, and private lodging facilities and group homes are equipped with fire alarms. Compared to facilities such as buildings and condominiums that are legally required to be installed, the number is small and the number of production is limited, so the cost is high and it is a bottleneck for popularization.

On the other hand, in an alarm system using a wireless interlocking 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. A fire alarm system is connected to the transfer adapter via a transfer signal line, and when a fire interlocking signal is received by the transfer adapter from the interlocking alarm system, the fire transfer signal is output to the fire alarm system and automatically notified 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, the transfer signal can be input and output. Since it is an existing product, there are few cost issues.

Therefore, if the existing transfer adapter is used, it is possible to easily and at low cost realize an inter-group transfer device that links fire alarms between a plurality of groups consisting of a plurality of alarms. The applicant of the present application is proceeding with a study on incorporating two alarm adapters into a housing to form an inter-loop alarm transfer device.

When multiple groups of interlocking alarms are interlocked using such an inter-group alarm, when a certain interlocking alarm is activated due to a fire, for example, "Woo Woo fire alarm has been activated. Please check." A fire alarm sound indicating the interlocking source is output, and another interlocking alarm in the same group is activated by transmitting a fire interlocking signal from the activated interlocking alarm. For example, "Woo, another fire alarm is activated. A fire alarm sounds indicating the interlocking destination such as "Please check." Is output. Furthermore, the interlocking alarms of other groups are activated by transmitting the fire interlocking signal via the intergroup transfer device, and as a result, the interlocking alarms of all groups are activated and the fire alarm is output. become.

When a fire alarm is output in this way, for example, in the case of a private lodging facility, the manager of the facility confirms the fire site, and if it is confirmed that there is no fire, it is installed in the interlocking alarm. Operate the test switch to stop the fire alarm.

However, in order to stop the fire alarm, it is necessary to enter the room where the interlocking alarm is installed and perform the stop operation, and it is necessary to obtain the consent of the guest, and it seems that it was handled during the absence. In some cases, if the circumstances are not fully explained, problems may occur later, and there is a problem that the operation management of the alarm system cannot be performed smoothly.

INDUSTRIAL APPLICABILITY The present invention facilitates operation management by enabling an authorized administrator or the like to stop and restart a fire alarm with a simple operation when a plurality of groups consisting of a plurality of alarms are linked by an intergroup transfer device. The purpose is to provide an alarm system that can be advanced to.

(Failure alarm and alarm stop all at once)
When a predetermined failure is detected, the alarms of each group output a failure alarm indicating the interlocking source, and also transmit a failure interlocking signal to other alarms in the group to output a failure alarm indicating the interlocking destination. Furthermore, the fault interlocking signal received from the alarm of one group is transmitted to the alarm of the other group by the intergroup transfer device arranged between the adjacent groups to output the fault alarm.
When the inter-group alarm transfer device detects the operation of the alarm simultaneous stop switch, it transmits an alarm simultaneous stop signal to the alarm device of each group via its own group alarm device and other inter-group alarm device. Then, the failure alarms output from each alarm are stopped all at once.

(Basic effect)
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. , The alarms of each group output a fire alarm indicating the interlocking source when a fire is detected, and also send a fire interlocking signal to other alarms in the group to output a fire alarm indicating the interlocking destination. In an alarm system in which a fire interlocking signal received from an alarm in one group is transmitted to an alarm in the other group by an inter-group alarm system arranged between adjacent groups to give an alarm. Is provided with a simultaneous alarm stop switch, and when the operation of the simultaneous alarm stop switch is detected, the simultaneous alarm stop signal is transmitted via an alarm device of its own group and another inter-group alarm device. Then, it was sent to the alarms of each group to stop the fire alarms output from each alarm all at once. Therefore, when a fire alarm is output, the authorized administrator can, for example, by floor. When divided into groups, the alarm simultaneous stop switch is operated as necessary, such as when going to an inter-group alarm system installed between adjacent groups, for example, at a landing on a staircase and confirming a non-fire. By doing so, the fire alarms output from the alarms of all groups can be easily stopped all at once, and there is no need to enter the room where the alarms are installed and operate them, from multiple alarms. It is possible to smoothly proceed with the operation management of the alarm system in which multiple groups are linked by the inter-group transfer device.

(Effect of simultaneous alarm stop via transfer adapter)
Further, in the inter-group signal transfer device, the first transfer adapter and the second transfer adapter are housed in a device housing provided with a panel door that can be opened and closed, and the first transfer adapter is an alarm device of its own group or When a fire interlocking signal is received from an intergroup transfer device arranged between adjacent groups, a fire transfer signal is output to the second transfer adapter, and the second transfer adapter outputs an alarm in its own group. A fire interlocking signal is transmitted to output a fire alarm indicating the interlocking destination, and the second signal transfer adapter sends a fire interlocking signal from the alarm system of its own group or the intergroup signal transfer device arranged between adjacent groups. When it is received, a fire transfer signal is output to the first transfer adapter, and a fire interlocking signal is transmitted from the first transfer adapter to an alarm in its own group to output a fire alarm indicating the interlocking destination. When the first transfer adapter and the second transfer adapter detect the operation of the alarm simultaneous stop switch, they send an alarm simultaneous stop signal to the alarms in their respective groups to stop the fire alarm and other alarms. Since the alarm simultaneous stop signal is sent to the inter-group alarm system to stop the fire alarm of the alarm system in each group, it has a wireless communication function with the alarm system and an input / output function of the signal transfer signal. An inter-group alarm system is constructed by incorporating a stand adapter, and the inter-group alarm system is installed in a place where fire interlocking signals from adjacent groups such as group boundaries can be received. In addition to the fire interlocking alarm within the group when a fire is detected, the fire interlocking alarm is output from all the alarms of other groups by transferring the fire interlocking signal by the intergroup transfer device, and the alarms are all at once. By operating the stop switch, it is possible to send an alarm simultaneous stop signal to stop the fire alarms of the alarms of all groups at once.

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 an input / output function of a transfer signal. It can be realized by changing the transfer adapter by adding a function to transmit an alarm simultaneous stop signal by a signal from the alarm simultaneous stop switch, and it can be realized easily and at low cost by manufacturing an intergroup transfer device, such as private lodging and It will be possible to promote the spread as a specific small-scale wireless self-fire alarm facility for facilities such as group homes.

(Effect of transferring alarm simultaneous stop signals between transfer adapters)
In addition, the first transfer adapter stops all alarms at the second transfer adapter when it receives a simultaneous alarm stop signal from an alarm device of its own group or another intergroup transfer device arranged between adjacent groups. The transfer signal is output, and the second transfer adapter sends an alarm simultaneous stop signal to the alarms in its own group to stop the fire alarm, and the second transfer adapter is the alarm device of its own group or When an alarm simultaneous stop signal is received from another intergroup transfer device arranged between adjacent groups, the alarm simultaneous stop transfer signal is output to the first transfer adapter, and the first transfer adapter owns itself. Since the alarm simultaneous stop signal is sent to the alarms in the group to stop the fire alarm, the alarm simultaneous stop transfer signal is internally transmitted between the two transfer adapters incorporated in the intergroup transfer device. By transmitting and receiving to, it is possible to appropriately transmit the alarm simultaneous stop signal to the alarm devices of all groups via the inter-group signal transfer device and to simultaneously stop the fire alarms from the alarm devices of all groups.

(Effect of stop control of interlocking source fire alarm and interlocking destination fire alarm)
In addition, the alarm is designed to stop both the fire alarm that indicates the interlocking source and the fire alarm that indicates the interlocking destination when the alarm simultaneous stop signal is received, so that the alarm does not enter the room where the alarm is installed. It is possible to easily and easily stop the fire alarms of all group alarms at once by operating the intergroup transfer device installed in a common space such as a stairs landing.

(Effect of stop control only for interlocking fire alarm)
In addition, the alarm does not stop the fire alarm that indicates the interlocking source when the alarm simultaneous stop signal is received, but stops the fire alarm that indicates the interlocking destination. Therefore, the alarm device of the fire occurrence location that became the interlocking source All fire alarms from other alarms are stopped, and it is possible to know the location of the fire from the continuously output fire alarm sound and perform initial fire extinguishing and evacuation guidance promptly and appropriately.

(Effect of alarm display and stop control of acoustic alarm)
In addition, the alarm stops the acoustic alarm without stopping the alarm display in the fire alarm indicating the interlocking source when the alarm simultaneous stop signal is received, and the fire alarm indicating the interlocking destination is the alarm display and the acoustic alarm. Since both are stopped, it is easy to identify the location of the fire by looking at the alarm display when the alarm is operating, such as when you go to the site and check for non-fire with the fire alarms stopped all at once. It will be possible to confirm.

(Effect of interlocking prohibition by alarm stop operation of alarm)
In addition, when the alarm detects the operation of the test switch during the fire alarm, the fire alarm is stopped without transmitting the alarm stop interlocking signal, so an unauthorized person such as a guest will be alerted during the fire. Even if the stop operation is performed, only the fire alarm of the operated alarm is stopped, and it is possible to solve the problem that the fire alarm is interlocked and stopped during the fire.

(Effect of placement of alarm simultaneous stop switch)
In addition, since the alarm simultaneous stop switch is provided in the device housing inside the child door provided on the panel door, the alarm simultaneous stop switch can be operated only by an authorized administrator who knows it. It will be possible, and it will be possible to reliably prevent unnecessary operations by other people.

(Effect of simultaneous ringing by canceling simultaneous alarm stop)
In addition, the inter-group alarm transfer device sounds a simultaneous alarm when it detects a release operation of the simultaneous alarm stop switch while the fire alarm output of the alarm devices of all groups is stopped all at once by operating the simultaneous alarm stop switch. Since the signal is sent to the alarms of each group via the alarm of its own group and the alarm of other groups, the fire alarms are output all at once from each alarm, so the fire alarm is temporarily issued. When a fire is confirmed by going to the site with the alarms stopped all at once, the output of the fire alarms from the alarms of all groups is output all at once by releasing the alarm simultaneous stop switch to encourage prompt evacuation action. This makes it possible to appropriately perform operation management by stopping the alarm and canceling the alarm stop based on the confirmation result of the fire.

(Effect of simultaneous alarm sounding via the transfer adapter)
Further, when the first signal transfer adapter and the second signal transfer adapter detect the release operation of the alarm simultaneous stop switch, the alarm simultaneous ringing signal is transmitted to the alarm device in each group to release the alarm stop. In addition to restarting the output of the fire alarm, a simultaneous alarm ringing signal was sent to the other inter-group alarm device to cancel the alarm stop of the alarm device in each group and restart the output of the fire alarm. An inter-group transfer device incorporating two adapters equipped with a wireless communication function with an alarm and a transfer signal input / output function is installed in a place where fire interlocking signals from adjacent groups such as group boundaries can be received. By doing so, the alarm simultaneous ringing signal can be transmitted by the release operation of the alarm simultaneous stop switch after the alarm simultaneous stop, and the fire alarm can be output all at once from the alarm devices of all the groups in which the alarm is stopped.

(Effect of transferring alarm simultaneous ringing signals between transfer adapters)
In addition, the first transfer adapter sounds a simultaneous alarm to the second transfer adapter when it receives a simultaneous alarm ringing signal from an alarm device of its own group or another intergroup transfer device arranged between adjacent groups. The transfer signal is output, the alarm simultaneous ringing signal is transmitted from the second transfer adapter to the alarm device in the own group, and the output of the fire alarm is restarted by canceling the alarm stop, and the second transfer adapter is When a simultaneous alarm ringing signal is received from the alarm device of its own group or another intergroup signal transfer device arranged between adjacent groups, the simultaneous alarm ringing signal is output to the first transfer adapter, and the first 1 Transfer of two units built into the inter-group transfer device because the alarm transfer signal is sent from the transfer adapter to the alarm device in the own group to restart the output of the fire alarm by canceling the alarm stop. By internally transmitting and receiving the alarm simultaneous sound transfer signal between the alarm adapters, the alarm simultaneous sound transfer signal is appropriately transmitted to the alarm devices of all groups via the inter-group signal transfer device, and the alarm devices of all groups. It enables the simultaneous sounding of fire alarms from.

(Effects of failure alarm and simultaneous alarm stop)
In addition, the alarms of each group output a failure alarm indicating the interlocking source when a predetermined failure is detected, and also transmit a failure interlocking signal to other alarms in the group to issue a failure alarm indicating the interlocking destination. It is output, and the fault interlocking signal received from the alarm of one group is transmitted to the alarm of the other group by the inter-group signal transfer device arranged between the adjacent groups to output the fault alarm, and the fault alarm is output between the groups. When the alarm transfer device detects the operation of the alarm simultaneous stop switch, the alarm simultaneous stop signal is transmitted to the alarm device of each group via the alarm device of its own group and the alarm device of other groups. Since the fault alarms output from each alarm are stopped all at once, it seems that the fault alarms are output from the alarms of all groups based on the fault detection such as equipment failure of the alarm, battery exhaustion, and automatic communication test error. In such a case, the failure alarm can be easily stopped and the failure can be dealt with by operating the inter-group signal transfer device, which makes it possible to further smoothly manage the operation of the alarm system.

[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 alarm 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 form the groups G1, G2, G3, and G4 as shown on the left side of the building 11, and the groups G1, G2, and G3. Different channel frequencies f1, f2, f3, and f4 are assigned to each of G4, and the interlocking alarms 10 of each group G1 to G5 use the channel frequencies f1 to f4 assigned to their own groups to signal. To send and receive.

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.

Inter-group transfer devices 12-12, 12-23, 12-34 are installed between groups G1 to G4 corresponding to the warning areas for each floor of the building 11. Since the inter-group signal transfer device 12-12, 12-23, 12-34 enables signals to be transmitted and received 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 two. When it is not necessary to distinguish between the intergroup transfer devices 12-12, 12-23, and 12-34 in the following description, it may be referred to as an intergroup transfer device 12.

The first transfer adapter 14 and the second transfer adapter 16 are incorporated in the inter-group transfer device 12-12, 12-23, 12-34.

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 has an interlocking alarm of the group G1 on the first floor. The same channel frequency f1 as that of the device 10 is set, and various signals including a fire interlocking signal are transmitted and received to and from the interlocking alarm device 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 second 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 inter-group transfer device 12-12 include a transmission unit and are connected by a transmission line that functions as internal wiring.

The first transfer adapter 14 incorporated in the inter-group transfer device 12-12 receives a fire interlocking signal of channel frequency f1 from the 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 that has input the fire transfer signal from the first transfer adapter 14 transmits a fire interlocking signal of channel frequency f2 to the interlocking alarm 10 in its own group G2 to indicate the interlocking destination. Output a fire alarm.

Further, the second transfer adapter 16 incorporated in the inter-group transfer device 12-12 transfers the first when it receives a fire interlocking signal of channel frequency f2 from the interlocking alarm 10 belonging to its own group G2. A fire transfer signal is output to the information adapter 14. The first transfer adapter 14 that has input the fire transfer signal from the second transfer adapter 16 transmits the fire interlocking signal of the channel frequency f1 to the interlocking alarm 10 in its own group G1 to indicate the interlocking destination. Output a fire alarm.

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 to 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, which is 10, and the interlocking alarm 10 of the group G1 send the inter-group alarms 12-12, 12-23, 12-34, and the inter-group alarms 12-12, 12-23, There is a second route sent from 12-34 to the interlocking alarm 10 of each loop G2, G3, G4.

As shown in FIG. 1, when the inter-group transfer devices 12-12, 12-23, and 12-34 are arranged at the landing of the stairs or the like and 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.

In addition, the inter-group alarm transfer device 12-12, 12-23, 12-34 is provided with an alarm simultaneous stop switch, and when the alarm simultaneous stop switch is operated, the alarm simultaneous stop signal is an interlocking alarm of its own group. The fire alarms transmitted to the interlocking alarms 10 of each group via the device 10 and other intergroup transfer devices and output from the interlocking alarms 10 of each group can be stopped all at once. .. Details of the simultaneous stop of fire alarms by the intergroup transfer device 12 will be clarified later.

[Functional configuration of interlocking alarm]
FIG. 2 is a block diagram showing the functional configuration of the 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. Operates on battery power (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. , Signals can be wirelessly transmitted and received 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 a specific low power radio station 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 from the fire reaches a predetermined concentration.
