Abstract

To make it possible to ensure reliability by checking an interlocking action through a test in the event that interlocking control is enabled by arbitrarily designating groups to be interlocked when plural groups each including plural alarms are interlocked with intergroup alarm transfer devices.SOLUTION: In a building 11, a signal is wirelessly transmitted or received among interlocked alarms 10, which belong to each of groups G0 to G5 on respective floors, in order to interlock the interlocked alarms. Each of intergroup alarm transfer devices 12-01 to 12-45 in which interlocking destination groups are registered in advance is installed between adjoining groups in order to interlock the groups. Each of the intergroup alarm transfer devices 12-01 to 12-45 transmits a test signal, which specifies one or plural groups as a test destination, through a test operation. When the test destination specified in the test signal received from the intergroup alarm transfer device includes the own group, the interlocked alarm 10 transmits a test response signal by performing a test action. The intergroup alarm transfer device receives the test response signal sent from the interlocked alarm 10, and notifies a result of the test.SELECTED DRAWING: Figure 1

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 fire alarm, 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, such as group homes that support household chores for the elderly and people with intellectual disabilities, who are not obliged to install fire alarm equipment, 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 source type alarm that detected the fire is, for example, "Woo Woo fire alarm has been activated. Please check." A fire alarm sound is output and the alarm display LED is turned on. On the other hand, the interlocking alarm device outputs a fire alarm sound such as "Woo, another fire alarm has been activated. Please check" and displays the alarm. The 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. Signal collisions may occur at the same time, and the frequency of signal collisions increases as the number of interlocking alarms installed in the warning area increases. Therefore, 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 interlocking alarms restricted so that the frequency of signal collision does not increase is set, and the plurality of 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 a signal from an interlocking alarm in the group and a signal from an 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 Transmission and reception can be performed reliably.

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 interlocking alarm when using a wireless signal, and in a parent-child system in which multiple slave units are arranged with respect to 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 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 wireless 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 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. 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, 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 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 mandatory 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 popularization.

For this reason, instead of repeaters, inter-group alarms that link fire alarms between multiple groups consisting of multiple alarms are being studied, and by using inter-group alarms, private lodging facilities and groups It is possible to realize an alarm system installed in a home or the like easily and at low cost.

When multiple groups of interlocking alarms are interlocked using such an intergroup transfer device, a fire alarm is output and a fire interlocking signal is output when a fire is detected by the interlocking alarms of a certain group. A fire alarm is output to the interlocking alarms in the same group, and a fire interlocking signal is transmitted to the interlocking alarms in other groups via the intergroup transfer device, and all groups A fire alarm can be output from an interlocking alarm.

By the way, in the event of a fire, in order to avoid confusion, it may be necessary to output a fire alarm from the interlocking alarms of the group in which the fire has occurred and the group adjacent to it. As described above, it is desired to construct an alarm system that can control the number of groups and the group range to be linked in the event of a fire by appropriately specifying them as necessary.

In addition, if the number of groups and the range of groups to be linked in the event of a fire can be specified and controlled, the group or group range specified as the link destination during periodic inspections and inspections as necessary For interlocking alarms, it is necessary to conduct tests to confirm that the fire alarm operation by interlocking control is performed normally to ensure the reliability of the alarm system.

The present invention confirms the interlocking operation by a test when interlocking a plurality of groups consisting of a plurality of alarms with an intergroup transfer device and when interlocking control is possible by arbitrarily setting the interlocking group. The purpose is to provide an alarm system that can ensure reliability.

(Warning system test)
The present invention constitutes a group consisting of a plurality of alarms for each warning area, and wirelessly transmits and receives signals between the alarms in the group, and the alarms of each group detect a fire. A fire alarm indicating the interlocking source is output, and a fire interlocking signal is transmitted to other alarms in the group to output a fire alarm indicating the interlocking destination, and an inter-group alarm system arranged between adjacent groups is used. In an alarm system in which a fire interlocking signal received from an alarm device of a group in which a fire is detected via the alarm system is transmitted to an alarm device of another group to give an alarm, the intergroup transfer device is one or more groups. Is transmitted as a test signal in which the test destination designation information is set, and the alarm in the group designated as the test destination in the test destination designation information performs a predetermined test operation and transmits a test response signal. And
The intergroup transfer device is further characterized in that it receives the test response signal from the alarm device and notifies the test result.

(Hop communication of test signal)
When the inter-group transfer device receives a test signal from one of the adjacent inter-group transfer devices regardless of whether or not the group to which it belongs is designated as the test destination in the test destination designation information, the inter-group transfer device transmits the test signal. It is transmitted to the other adjacent intergroup transfer device.

(Test signal transmission by selecting test destination designation information)
The inter-group transfer device
Multiple types of test destination designation information in which one or a plurality of multiple groups are designated as test destinations are stored in advance.
A predetermined test destination designation information selected by a predetermined operation from a plurality of types of test destination designation information is set as a test signal and transmitted.

(Type of test destination designation information)
The inter-group signal transfer device is stored in advance as a plurality of types of test destination designation information, such as self-group designation information, two-group designation information adjacent to the self, fire floor, direct upper floor and basement floor group designation information. Alternatively, at least one of the designated information of all groups is set as a test signal and transmitted.

(Notification of test results based on test response signals)
When the alarm receives a test signal that specifies its own group from the inter-group transfer device, it sets its own alarm identification information in the test response signal and transmits it.
Based on the alarm identification information of the test response signal received from the alarm, the inter-group signal transfer device notifies the test normality when the test response signal is received from all the alarms belonging to its own group, and notifies its own group. When the test response signal is not received from all the alarms belonging to, the test abnormality is notified.

(Test operation of alarm)
When the alarm receives a test signal specifying its own group from the inter-group transfer device, the alarm displays the test operation without giving a voice alarm.

(Basic effect)
The present invention constitutes a group consisting of a plurality of alarms for each warning area, and wirelessly transmits and receives signals between the alarms in the group, and the alarms of each group detect a fire. A fire alarm indicating the interlocking source is output, and a fire interlocking signal is transmitted to other alarms in the group to output a fire alarm indicating the interlocking destination, and an inter-group alarm system arranged between adjacent groups is used. In an alarm system in which a fire interlocking signal received from an alarm device of a group in which a fire is detected via the alarm system is transmitted to an alarm device of another group to give an alarm, the intergroup transfer device is one or more groups. Is transmitted as a test signal in which the test destination designation information is set, and the alarm in the group designated as the test destination in the test destination designation information performs a predetermined test operation and transmits a test response signal. Further, since the inter-group information transfer device receives the test response signal from the alarm and notifies the test result, a specific group or a group within a specific range is designated as the interlocking destination. When the interlocking alarm is controlled, the alarms belonging to the test destination group are tested by transmitting the test signal that specifies a specific group or a group within a specific range as the test destination, and the test results are normal. It is possible to ensure the reliability of the alarm system by knowing whether it has operated or causing an abnormality and taking appropriate measures such as repairing the alarm that has caused the abnormality.

(Effect of hop communication of test signal)
Further, when the inter-group transfer device receives a test signal from one of the adjacent inter-group transfer devices, the test is performed regardless of whether or not the group to which the inter-group transfer device belongs is designated as the test destination in the test destination designation information. Since the signal is transmitted to the other adjacent intergroup transfer device, the test signal including the test destination designation information transmitted from the intergroup transfer device that performed the test operation is transmitted to a plurality of groups by the so-called bucket relay method. It becomes hop communication that is sent sequentially according to the arrangement of the inter-communication device, the test signal is sent to the alarms of all groups, and the alarm that has its own group in the test destination designation information of the received test signal is the test operation. By performing the above and transmitting the test response signal, it is possible to easily and surely perform the test of the alarm device for a specific group or a specific group range.

(Effect of test signal transmission by selecting test destination designation information)
Further, the inter-group signal transfer device stores in advance a plurality of types of test destination designation information in which one or a plurality of multiple groups are designated as test destinations, and by performing a predetermined operation from among the plurality of types of test destination designation information. Since the selected predetermined test destination designation information is set in the test signal and transmitted, a test targeting a specific group or group range required from a plurality of types of test destination designation information prepared in advance. The test operation can be easily performed by selecting the pre-specified information.

(Effect of the type of test destination designation information)
In addition, the inter-group signal transfer device is stored in advance as a plurality of types of test destination designation information, such as own group designation information, two groups designation information adjacent to the self, fire floor, direct upper floor, and basement floor group designation. Since at least one of the information or the designated information of all the groups is set as the test signal and transmitted, the test in which one of the groups adjacent to the intergroup transfer device is designated and the two adjacent groups are transmitted. A simple and reliable test can be performed by arbitrarily selecting a designated test, a test that specifies a group on the fire floor, the floor directly above and the basement floor, or a test that specifies the entire building that specifies all groups, as necessary. Is possible.

(Effect of notification of test results based on test response signal)
In addition, when the alarm receives a test signal that specifies its own group from the intergroup alarm, the alarm sets its own alarm identification information in the test response signal and transmits it, and the intergroup alarm transfers. Based on the alarm identification information of the test response signal received from the alarm, when the test response signal is received from all the alarms belonging to the own group, the test normality is notified and from all the alarms belonging to the own group. Since the test abnormality is notified when the test response signal is not received, the alarm device of the group tested with the test signal from the intergroup transfer device that performed the test operation performs the test operation normally. Then, the test response signal from the alarm is received by the intergroup transfer device corresponding to the own group, and the test response signal is received from all the alarms in the group from the alarm identification information included in the test response signal. If the test is normal, the test is judged to be normal and notified. On the other hand, if the test response signal is not received from all the alarms in the group, the test abnormality is judged and notified, and the alarm that has become the test abnormality is notified. It enables appropriate measures such as repair and replacement.

(Effect of test operation of alarm)
In addition, when the alarm receives a test signal that specifies its own group from the inter-group transfer device, the test operation is displayed without giving a voice alarm, so the alarm device specifies the test destination group. Since no voice message or notification sound indicating the test operation is output even if the test operation is performed, the test of the alarm system does not cause unnecessary confusion.

In addition, the alarm that operates normally by the test signal is displayed as a test operation by blinking the operation indicator light, etc., and when a test abnormality is notified by the inter-group transfer device, the operation indicator light in the group By searching for an alarm that is off without blinking, it is possible to easily and easily find an alarm that is causing a test abnormality without performing a test operation, and take measures such as repair and replacement.

[Overview of warning 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, for example, a building 11 having 5 floors above ground and 1 floor below ground, such as a private lodging facility, and the warning area is a warning for each floor of B1F, 1F to 5F. For example, five wirelessly interlocking interlocking alarms 10 that function as alarms are installed in each of the warning areas on each floor.

Here, the five interlocking alarms 10 installed on the B1F to 5F form the groups G0, G1, G2, G3, G, G5 as shown on the left side of the building 11, and the group G0. , G1, G2, G3, G4, G5 are each assigned different channel frequencies f0, f1, f2, f3, f4, f5, and the interlocking alarms 10 of each group G0 to G5 are assigned to their own group. Signals are transmitted and received using the assigned channel frequencies f0 to f5. Note that the same frequency f0 may be assigned to the separate groups G0 and G5 such as B1F and 5F if there is no risk of interference.

The interlocking alarms 10 provided in the groups G0 to G5 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.

Intergroup transfer devices 12-01, 12-12, 12-23, 12-34, 12-45 are installed between groups G0 to G5 corresponding to the warning areas for each floor of the building 11. The intergroup transfer devices 12-01 to 12-45 enable signals to be transmitted and received to and from both interlocking alarms 10 provided in groups on adjacent floors, so that, for example, a staircase connecting the floors It will be installed on the wall of the landing. When it is not necessary to distinguish between the intergroup transfer devices 12-01 to 12-45 in the following description, the intergroup transfer device 12 may be used.

The first transfer adapter 14 and the second transfer adapter 16 are incorporated in the inter-group transfer devices 12-01 to 12-45.

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 functioning as internal wiring.

The first transfer adapter 14 and the second transfer adapter 16 provided in the inter-group transfer device 12 store interlocking destination designation information for designating one or a plurality of groups to be fire interlocking destinations. When a fire interlocking signal is received from the interlocking alarm 12 of the group, the fire interlocking signal in which the preselected interlocking destination designation information is set is transmitted.

In the present embodiment, the inter-group transfer device 12 has, as interlocking destination designation information, for example, self-group designation information, designation information of two groups adjacent to the self, group designation information of the fire floor, the immediate upper floor, and the basement floor. Or, the designated information of all groups is stored, and by selecting one of the linked destination designated information in advance, when a fire linked signal is received from the linked alarm 12 of the own group, it is selected. A fire interlocking signal with the interlocking destination designation information set is transmitted.

For example, when the first transfer adapter 14 of 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, the interlocking destination stored in advance. The designated information is read, set as a fire transfer signal, and output to the second transfer adapter 16.

The second transfer adapter 16 that has input the fire transfer signal from the first transfer adapter 14 generates a fire interlocking signal including the interlocking destination designation information of the fire transfer signal, and uses the channel frequency f2 to interlock with the fire. The signal is transmitted to the interlocking alarm 10 in its own group G2.

The interlocking fire alarm 10 of the group G2 outputs a fire alarm indicating the interlocking destination when its own group G2 is included in the interlocking destination designation information of the fire interlocking signal received from the second transfer adapter 16. If the interlocking destination designation information of the received fire interlocking signal does not include its own group G2, only the relay operation is performed without outputting the fire alarm.

Further, the second transfer adapter 16 of the intergroup transfer device 12-12 receives a fire interlocking signal of channel frequency f2 from the interlocking alarm 10 belonging to its own group G2, and the interlocking destination stored in advance. The designated information is read, set as a fire transfer signal, and output to the first transfer adapter 14.

The first transfer adapter 14 that has input the fire transfer signal from the second transfer adapter 16 generates a fire interlocking signal including the interlocking destination designation information of the fire transfer signal, and uses the channel frequency f1 to interlock the fire. The signal is transmitted to the interlocking alarm 10 in its own group G1.

The interlocking fire alarm 10 of the group G1 outputs a fire alarm indicating the interlocking destination when its own group G1 is included in the interlocking destination designation information of the fire interlocking signal received from the first transfer adapter 14. If the interlocking destination designation information of the received fire interlocking signal does not include its own group G1, the fire alarm is not output and only the relay operation is performed.

Such functions of the first transfer adapter 14 and the second transfer adapter 16 also include the contents of the interlocking destination designation information and the interlocking destination designation information for the intergroup transfer devices 12-01, 12-23, 12-34, 12-45. Same except that the channel frequencies used are different.

Here, the communication route of the fire interlocking signal between the groups G0 to G5 goes through only the interlocking alarm 10 and the intergroup transfer device 12 in each group and the intergroup transfer device 12. There is a route, and communication is performed by either or both routes depending on the communication status.

Therefore, the fire interlocking signal including the interlocking destination designation information transmitted from the intergroup reporting device 10 corresponding to the group in which the fire is detected corresponds to the arrangement of a plurality of intergroup reporting devices by the so-called bucket relay method. The fire interlocking signal is sent to the interlocking alarms 10 of all the groups, and the interlocking alarm 10 has its own group in the interlocking destination designation information of the received fire interlocking signal. By outputting a fire alarm from, the fire alarm can be linked to a specific group or a specific group range.

[Outline of warning system test]
The intergroup transfer devices 12-01 to 12-45 provided in the building 11 of FIG. 1 can perform a test by designating one or a plurality of groups by a predetermined test operation.

The test by the inter-group transfer device 12 is performed based on the test destination designation information stored in advance. The inter-group signal transfer device 12 stores a plurality of types of test destination designation information in which one or a plurality of groups are designated as test destinations, and if necessary, arbitrary test destination designation information is selected to perform a test operation. When this is done, a test signal in which the selected test destination designation information is set is transmitted.

In the present embodiment, the inter-group transfer device 12 has test destination designation information such as self-group test destination designation information, two groups of test destination designation information adjacent to itself, a fire floor, an immediate upper floor, and a basement floor. The test destination designation information of the group or the test destination designation information of all the groups is stored, and the test can be performed by selecting any of the test destination designation information.

For example, taking the inter-group transfer device 12-12 as an example, the first transfer adapter 14 has test destination designation information of its own group G1 and test destination designation information of two groups G1 and G2 adjacent to itself. The test destination designation information of the fire floor group G1, the immediate upper floor group G2 and the basement floor group G0, or the test destination designation information designated by the entire building where all groups G0 to G5 are designated is stored, and if necessary, arbitrary The test destination designation information can be selected, set as a test signal, and transmitted.

Further, the second transfer adapter 16 of the inter-group transfer device 12-12 has test destination designation information of its own group G2, test destination designation information of two groups G1 and G2 adjacent to itself, fire floor group G2, and so on. The test destination designation information of the group G3 on the immediate upper floor and the group G0 on the basement floor, or the test destination designation information designated by the entire building where all groups G0 to G5 are designated is stored. Similarly, any test destination is stored as needed. The specified information can be selected, set as a test signal, and transmitted.

Here, since the test by the inter-group transfer device 12 is performed for the group performing the fire interlocking, the test destination designation information and the interlocking destination designation information have the same designated contents, and are set to the test signal and transmitted. It depends on whether it is sent or set as a fire interlocking signal.

For example, when a test operation is performed by the first transfer adapter 14 of the intergroup transfer device 12-12, predetermined test destination designation information stored in the test operation is read out, set as a test signal, and is set to a channel. The test signal is transmitted to the interlocking alarm 10 in its own group G1 using the frequency f1. Further, a test transfer signal in which the same test destination designation information is set is output from the transfer adapter 14 to the second transfer adapter 16, and the second transfer adapter 16 that receives this output uses the channel frequency f2. A test signal set with the same test destination designation information is transmitted to the interlocking alarm 10 in its own group G2.

Further, the test signal transmitted from the first transfer adapter 14 of the intergroup transfer device 12-12 is transmitted to the interlocking alarm 10 of the group G0 via the adjacent intergroup 12-01, and also. The test signal transmitted from the second transfer adapter 16 of the intergroup transfer device 12-12 is of the group G3, G4, G5 via the intergroup transfer device 12-23, 12-34, 12-45. It is transmitted to the interlocking alarm device 10.

That is, when a test operation is performed with an arbitrary intergroup transfer device 12, an interlocking alarm of all groups G0 to G5 is performed by hop communication via another intergroup transfer device, as in the case of a fire interlocking signal. The vessel 10 receives a test signal in which the same test destination designation information is set.

When the interlocking alarms 10 of the groups G0 to G5 receive the test signal from the arbitrary intergroup transfer device 12 that has performed the test operation, the test destination designation information of the received test signal includes its own group. If so, a predetermined test operation is performed and a test response signal including its own source code is transmitted. Here, as the predetermined test operation, no voice alarm or the like is output, and only the test operation display that blinks or turns on the operation indicator lamp is used.

On the other hand, the interlocking alarms 10 of the groups G0 to G5 do not perform the test operation and also transmit the test response signal when the test destination designation information of the received test signal does not include their own group. Absent.

The test response signal transmitted from the interlocking alarm 10 that performed the test operation is received by the first transfer adapter 14 or the second transfer adapter 16 of the intergroup transfer device 12 of the same group, and is within its own group. When the test response signal is received from all the interlocking alarms 10, it is judged that the test is normal, and if necessary, the notification indicating the test is normal is given, and the test response signal is received from all the interlocking alarms 10. If not, it is determined that the test is abnormal, an alarm indicating the test abnormality is notified, and a response such as repair of the interlocking alarm device 10 that has become the test abnormality is urged.

[Functional configuration of interlocking alarm]
(Functional configuration)
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 light 26, a speaker 28, and an alarm stop 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 one of the six channel frequencies f0 to f5 in the 400 MHz band based on the instruction from the interlocking alarm control unit 18 based on the initial settings and the like, and sets another interlocking type belonging to the same group. Signals can be transmitted and received wirelessly to and from the alarm device 10.

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) 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.

When the signal format of the fire interlocking signal transmitted / received by the communication unit 20 is, for example, a fixed length code,
The source code, event code, interlocking source group code (interlocking source group information), interlocking destination designation information, and the like are included.

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. 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 alarm stop 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 an alarm is given in a normal state. When the stop switch 30 is operated, a fire alarm for inspection is output at a low volume.

(Fire alarm control function)
The control function of the interlocking alarm control unit 18 is realized by executing a program, and has the following fire alarm control function. 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 Woo fire alarm has been activated.""Pleasecheck" 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 instructs the communication unit 20 when a fire is detected, and controls the communication unit 20 to transmit a fire interlocking signal from the communication unit 20 to another interlocking alarm using the channel frequency assigned to the group. I do.

Further, when the interlocking alarm control unit 18 receives a fire interlocking signal from another interlocking alarm 10 belonging to the same group in the communication unit 20, the interlocking source group code of the fire interlocking signal is its own group. , The speaker 28 repeatedly outputs an alarm sound indicating, for example, "Woo, another fire alarm has been activated. Please check", and at the same time, the operation indicator light 26 blinks, for example, to indicate the interlocking destination. Controls to output the fire alarm shown.

Further, when the interlocking alarm control unit 18 receives the fire interlocking signal from the intergroup signal transfer device 12 in the communication unit 20, the interlocking alarm control unit 18 includes its own group in the interlocking destination designation information of the fire interlocking signal. As an alarm sound indicating the interlocking destination, an alarm sound indicating the interlocking destination is repeatedly output from the speaker 28, for example, an alarm sound indicating "Woo, another group of fire alarms have been activated. Please check", and at the same time, the operation indicator lamp 26 For example, a fire alarm that blinks to indicate the interlocking destination is output. On the other hand, when the interlocking destination designation information of the received fire interlocking signal does not include its own group, the interlocking alarm control unit 18 controls to relay and transmit the fire interlocking signal without performing the fire alarm operation. Do.

Further, when the interlocking alarm control unit 18 detects the alarm stop operation of the alarm stop switch 30 during the output of the fire alarm indicating the interlocking source, the interlocking alarm control unit 18 stops the alarm sound from the speaker 28 and displays the operation indicator lamp 26. Is stopped, and an alarm stop interlocking signal is transmitted to another interlocking alarm device to control the fire alarm indicating the interlocking destination to be stopped. In this case, the alarm stop interlocking signal is not transmitted to the other interlocking alarm device 10, and the general user such as a guest performs the alarm stop operation at a place other than the place where the fire occurs, so that a fire alarm is issued during the fire. Solve the problem of interlocking stop.

Further, the interlocking alarm control unit 18 performs a communication test within the group, a battery voltage drop monitor, and a circuit failure monitor. When a communication error, a battery voltage drop, or a circuit failure is detected, the speaker 28 determines the value. The failure alarm sound is output, the operation indicator lamp 26 is blinked to output a failure alarm, and the failure interlocking signal is transmitted from the communication unit 20 to the other interlocking alarm device 10 and the intergroup transfer device 12. By doing so, control is performed to output a failure alarm from the interlocking alarm devices 10 of all groups. In addition, the failure alarm of the interlocking destination is limited to the alarm display by the operation of the operation indicator lamp in order to avoid confusion.

(Test control function)
When the interlocking alarm control unit 18 receives the test signal from the other interlocking alarm 10 or the intergroup transfer device 12 belonging to the same group in the communication unit 20, the interlocking alarm control unit 18 sets the test destination designation information in the test signal. When it is determined that a self-group is included in, a test operation display for blinking or lighting the operation indicator lamp 26 is performed, and control is performed for transmitting a test response signal including a source code. In this case, the speaker 28 does not output a voice message or a notification sound indicating the test operation, and does not cause unnecessary confusion.

Further, when the interlocking alarm control unit 18 determines that the test destination designation information set in the test signal received by the communication unit 20 does not include its own group, the operation indicator lamp 26 is activated. And the test response signal is not transmitted, and the test signal is relayed as necessary.

As shown in FIG. 5, the first transfer adapter 14 and the second transfer adapter 16 provided in the intergroup transfer devices 12-01 to 12-45 are designated as interlocking destinations as shown on the right side. Information tables 100-01 to 100-54 are arranged in the memory.

For example, in the transfer destination designation information table 100-12 arranged in the first transfer adapter 14 of the intergroup transfer device 12-12, the fire floor / directly above the first transfer adapter 14 in FIG. 3 (B) is shown. -The link destination designation information "G1 → G1, G2, G0" designated on the basement floor is stored, and FIG. 3 (B) is shown in the link destination designation information table 100-21 arranged in the second transfer adapter 16. The interlocking destination designation information "G2 → G2, G3, G0" for designating the fire floor, the floor directly above, and the basement floor of the second transfer adapter 14 of the above is stored.

(Test destination designation information)
The interlocking destination designation information shown in FIG. 4 can be used as it is as the test destination designation information.

The test destination designation information table of FIGS. 4A to 4E is divided into each of the intergroup transfer devices 12-01 to 12-45 shown in FIG. 1, and the first transfer adapter 14 and the second transfer are transferred. The adapter 16 is shown, and further, as a type of test destination designation,
(1) Designation of test destinations for self-groups (2) Designation of test destinations for adjacent groups (3) Designation of test destinations for fire floors, directly above floors, and basement floors (4) Designation of test destinations for the entire building.

For example, taking the test destination designation of the fire floor, the floor directly above, and the basement floor as the test destination designation information of the intergroup transfer device 12-12 in FIG. 4 (B), the test destination is attached to the first transfer adapter 14. (G1 → G1, G2, G0) is set as the designated information, and (G1 → G2, G3, G0) is set as the test destination designation information in the second transfer adapter 16.

When FIG. 4 is used as the test destination designation information, FIG. 5 illustrates a case where the test destination designation information for designating the fire floor, the floor directly above, and the basement floor of FIG. 4 as the test destination is stored in the intergroup transfer device of FIG. It becomes the explanatory diagram shown in the above.

As shown in FIG. 5, the first transfer adapter 14 and the second transfer adapter 16 provided in the intergroup transfer devices 12-01 to 12-45 are on the memory as shown on the right side. The arranged interlocking destination designation information tables 100-01 to 100-54 function as a test destination designation information table, and for example, the transfer destination designation information arranged in the first transfer adapter 14 of the intergroup transfer device 12-12. Table 100-12 shows the test destination designation information of the fire floor / direct floor / basement floor designation (corresponding to the test destination designation of the fire floor / direct upper floor / basement floor) of the first transfer adapter 14 in FIG. 3 (B). “G1 → G1, G2, G0” is stored, and the interlocking destination designation information table 100-21 arranged in the second transfer adapter 16 shows the fire of the second transfer adapter 14 in FIG. 3 (B). The test destination designation information "G2 → G2, G3, G0" designated for the floor, the floor directly above, and the basement floor is stored.

The interlocking destination designation information table and the test destination designation information table may be separately arranged in the memory to store the respective designation information.

(Fixed length fire interlocking signal)
FIG. 6 is an explanatory diagram showing a signal format of a fixed-length fire interlocking signal that specifies an interlocking destination group, and FIG. 6A shows a fire interlocking signal 60 transmitted from the interlocking alarm 10 in FIG. B) shows the interlocking transfer signal 72 transmitted from the group transfer device 12.

As shown in FIG. 6A, the fire interlocking signal 60 transmitted from the interlocking alarm 10 is a fixed-length signal, and the source code 62, the event code 64, the interlocking source group code 66, and the interlocking destination designation information 68. And a checksum 70.

The source code 62 is a code indicating a source, and uses, for example, a serial number of an interlocking alarm. The event code 64 is a code representing an event content such as a fire alarm code, an alarm stop code, a failure code, and a test code. When a fire alarm code is set in the event code 64, it becomes a fire interlocking signal, and the event code 64 When the test code is set to, it becomes the test code. The interlocking source group code 66 is a code indicating a source group, and for example, a group name or a group ID is used.

The interlocking destination designation information 68 arranges the flag bits G0 to G5 for each group corresponding to the groups G0 to G5 shown in FIG. 1, and when transmitting from the interlocking alarm device 10, the interlocking destination designation information 68 Since the interlocking destination group is not specified by, the flag bits G0 to G5 are all initialized to invalid bits 0.

In the fire interlocking signal 72 shown in FIG. 6B, a fire was detected by the interlocking alarm 10 of the group G2 shown in FIG. 4, and the second transfer adapter 16 of the group transfer device 12-12 was used from the group G2. An example is a fire interlocking signal 72 that receives a fire interlocking signal and transmits it via a transfer from the second transfer adapter 16 to the first transfer adapter 14.

In the interlocking destination designation information table 100-21 of the second transfer adapter 16 used in this case, the interlocking destination designation information "G2 → G2," which links the fire floor group G2, the immediate upper floor group G3, and the basement floor group G0, is shown. Since "G3, G0" is stored, the flag bits corresponding to the groups G0, G2, and G3 of the interlocking destination designation information 68 in the fire interlocking signal 72 are set in the valid bit 1, and the other flag bits are invalid bits. It is set to 0.

Therefore, when the fire interlocking signal 72 is transmitted from the first transfer adapter 14 of the intergroup transfer device 12-12 to the group G1, the interlocking alarm 10 of the group G1 receives the interlocking destination designation information of the fire interlocking signal. Since 68 does not include its own group G1, no alarm operation is performed, the interlocking alarm of group G1 is skipped, and the fire interlocking signal 72 goes to group G0 via the next intergroup transfer device 12-01. Will be sent.

When the fire interlocking signal 72 is transmitted from the first transfer adapter 14 of the intergroup transfer device 12-01 to the group G0, the interlocking alarm 10 of the group G0 sends the interlocking destination designation information 68 of the received fire interlocking signal. Detects that its own group G0 is included and outputs a fire alarm. As a result, a fire alarm for group G0 on the basement floor is issued in conjunction with a fire alarm for group G2 on the second floor.

Further, the fire interlocking signal from the fire floor group G2 was received by the first transfer adapter 14 of the intergroup transfer device 12-23, and "G2 → G2, G3, G0" was set as the interlocking destination designation information. The fire interlocking signal is transmitted to the group G3 via the second transfer adapter 16, and the interlocking alarm 10 of the group G3 includes its own group G3 in the interlocking destination designation information 68 of the received fire interlocking signal. Detects that and outputs a fire alarm. As a result, the fire alarm of the group G3 on the immediately above floor is also issued in conjunction with the fire alarm of the group G2 on the second floor. Further, the fire interlocking signal from the second transfer adapter 16 of the inter-group transfer device 12-23 is also transmitted to the groups G4 and G5 via the inter-group transfer device 12-34, 12-45. , The interlocking alarm 10 of the groups G4 and G5 does not perform the alarm operation because the interlocking destination designation information 68 of the received fire interlocking signal does not include its own group G4 and G5.

In addition to this, the fire interlocking signal includes the number of relays, and the number of relays is a code that decreases by 1 each time the interlocking alarm 10 relays the fire interlocking signal. If 3 times is initially set, the number of relays will be zero after 3 relays, and the next relay will not be performed. This prevents the fire interlocking signal from being relayed indefinitely.

(Fixed length test signal)
The fire interlocking signal 60 shown in FIG. 6A becomes a test signal by setting a test code in the event code 64, and in this case, the interlocking destination designation information 68 becomes the test destination designation information.

For example, it is said that the second transfer adapter 16 of the intergroup transfer device 12-12 installed between the groups G1 and G2 in FIG. 1 was used to perform a test operation in which the fire floor, the floor directly above, and the basement floor were designated as test destinations. Then, a test code is set in the event code 64 of the fire interlocking signal 72 shown in FIG. 6B, and the interlocking destination designation information 68 is transmitted to the group G2 on the immediately upper floor with the test signal set with the same effective bit 1. The same test signal is transmitted to all remaining groups G0, G1, G3, G4, G5 via other intergroup transfer devices 12-01, 12-23, 12-34, 12-45.

In this way, the test signals are sent to all the groups G0 to G5, and the interlocking alarms 10 of the groups G2, G3, and G0 designated as the test destinations are self-identified in the test destination designation information of the received test signals. It is determined that a group is included, a test operation is performed, an operation indicator is activated, and a test response signal is transmitted.

On the other hand, the interlocking alarms 10 of the groups G1, G4, and G5, which are not designated as test destinations, determine that their own group is not included in the test destination designation information of the received test signal, and perform the test operation and The test response signal is not transmitted.

(Variable length fire interlocking signal)
FIG. 7 is an explanatory diagram showing a signal format of a variable-length fire interlocking signal that specifies an interlocking destination group, and FIG. 7A shows a fire interlocking signal 74 transmitted from the interlocking alarm 10 in FIG. 7 (A). B) shows the fire interlocking transfer signal 76 transmitted from the group transfer device 12.

As shown in FIG. 7A, the fire interlocking signal 60 transmitted from the interlocking alarm 10 is a variable length signal, and is composed of a source code 62, an event code 64, an interlocking source group code 66, and a checksum 70. Will be done. The number of relays is omitted.

The fire interlocking signal 76 transmitted from the intergroup transfer device shown in FIG. 7B adds interlocking destination designation information 78 to the fire interlocking signal 74 transmitted from the interlocking alarm 10 in FIG. 7A. The interlocking destination group code registered in the interlocking destination designation information table of either the first transfer adapter 14 or the second transfer adapter 16 which is the receiving side of the intergroup transfer device 12 is set and transmitted. Let me.

The interlocking alarm system 10 that has received the fire interlocking signal 76 shown in FIG. 7B will give a fire alarm when it detects that the interlocking destination designation information 78 of the received fire interlocking signal 76 includes its own group. Is output, and when it is detected that the self-group is not included in the interlocking destination designation information 78 of the received fire interlocking signal 76, only the relay operation is performed without outputting the fire alarm.

(Variable length test signal)
The fire interlocking signal 76 transmitted from the intergroup transfer device shown in FIG. 7B becomes a test signal by setting a test code in the event code 64, and in this case, the interlocking destination designation information 78 is the test destination designation information. Become.

[Control operation of interlocking alarm]
FIG. 8 is a flowchart showing the control operation of the interlocking alarm, and the control operation is performed by the interlocking alarm control unit 18 shown in FIG.

As shown in FIG. 8, the interlocking alarm control unit 18 provided in the interlocking alarm 10 performs fire monitoring in step S1, and in step S2, for example, the smoke concentration detection signal from the sensor unit 24 has a predetermined threshold value. If a fire is determined by exceeding the above, the process proceeds to step S3, and the speaker 28 repeatedly outputs, for example, "Woo Woo fire alarm has been activated. Please check", and the operation indicator lamp 26 is turned on, for example, to indicate the interlocking source. Output a fire alarm. Further, in step S3, for example, a fire interlocking signal in which all the flag bits of the interlocking destination designation information 68 shown in FIG. 6A are initialized to bit 1 or bit 0 is transmitted.

Subsequently, when the interlocking alarm control unit 18 determines in step S4 that a signal has been received from another interlocking alarm 10 or the intergroup transfer device 12 in the same group, the interlocking alarm control unit 18 proceeds to step S5 and self-responds to the received signal. Determine if the group is included. Here, if the received signal is a fire interlocking signal, it can be determined whether or not its own group is included by examining the source group code or the interlocking destination designation information, and if it is a test signal, a test is performed. It is possible to determine whether or not the own group is included by examining the pre-specified information.

When the interlocking alarm control unit 18 determines in step S5 that the received signal includes its own group, it proceeds to step S6 and determines whether or not the event code of the received signal is a fire alarm code. If the fire alarm code is determined in step S6, the process proceeds to step S7 to output a fire alarm indicating the interlocking destination.

Here, when a fire interlocking signal is received from another interlocking alarm 10 in the same group, it can be determined that the source group code of the received fire interlocking signal includes its own group. In this case, in step S7, for example, "Woo, another fire alarm has been activated, please check" is repeatedly output from the speaker 28, and the operation indicator lamp 26 is blinked, for example.

On the other hand, when a fire interlocking signal is received from the intergroup transfer device 12, it can be determined that the interlocking destination designation information of the received fire interlocking signal includes its own group. In this case, In step S7, for example, "Woo Woo, please confirm that the fire alarms of other groups have been activated" is repeatedly output from the speaker 28, and the operation indicator lamp 26 is blinked, for example.

Further, the interlocking alarm control unit 18 proceeds to step S8 if the event code of the received signal is not a fire alarm code in step S6, determines whether or not it is a test code, and if the test code is determined, step S9. The test operation is displayed by blinking or lighting the operation indicator lamp 26, and a test response signal including the source code is transmitted.

Further, when the event code of the received signal is not the test code in step S8, although not shown, if the control corresponding to another event code is performed or the number of relays is less than the predetermined number of relays, a fire occurs. Relay transmission of interlocking signals.

Subsequently, when the interlocking alarm control unit 18 determines in step S10 the alarm stop operation by the alarm stop switch 30, the process proceeds to step S8, and when it determines that the alarm is in progress, the interlocking alarm control unit 18 proceeds to step S13 to stop the output of the fire alarm.

Further, the interlocking alarm control unit 18 determines the alarm stop operation by the alarm stop switch 30 in step S11 and proceeds to step S12. If it determines that the alarm is not in progress, the interlocking alarm control unit 18 proceeds to step S14 to give a fire alarm for inspection. Is output. As for the test fire alarm output in step S14, for example, "Woo Woo fire alarm has been activated, please check" is output once at a low volume, and the interlocking alarm 10 is operating normally. Inform.

[Control operation of inter-adapter transfer device]
FIG. 9 is a flowchart showing the control operation of the first transfer adapter provided in the intergroup transfer device, and is controlled by the adapter control unit 32 shown in the first transfer adapter 14 of FIG. The control operation of the second transfer adapter 16 is the same.

As shown in FIG. 9, the adapter control unit 32 of the first transfer adapter 14 is
When it is determined in step S21 that the fire interlocking signal has been received from the interlocking alarm 10 in the same group or another intergroup transfer device 12, the process proceeds to step S22, and the interlocking destination designation information stored in advance is stored in the interlocking destination designation information group. Read from, and proceed to step S23 to transmit the fire alarm signal in which the interlocking destination designation information is set to the second transfer adapter 16.

Subsequently, when the adapter control unit 32 of the first transfer adapter 14 determines that the fire transfer signal transmitted from the second transfer adapter 16 has been received in step S24, the process proceeds to step S25, and the received fire transfer signal is used. A fire interlocking signal with the acquired interlocking destination designation information is generated and transmitted to the interlocking alarm 10 of the own group, and the own group is set to either the interlocking source group code of the fire interlocking signal or the interlocking destination designation information. If is included, a fire alarm is output, and if both the interlocking source group code and the interlocking destination designation information of the fire interlocking signal do not include its own group, the fire alarm is not output.

Subsequently, when the adapter control unit 32 of the first transfer adapter 14 detects the switch operation of the alarm simultaneous ringing switch 48 in step S26, the process proceeds to step S27, sets the fire alarm code in the event code, and sets the interlocking destination designation information. A fire interlocking signal for alarm simultaneous sounding that specifies all groups is transmitted to its own group and also transmitted to an adjacent group via the second transfer adapter 16, whereby the fire interlocking signal for alarm simultaneous sounding is further transmitted. , It is transmitted to the interlocking alarms of all groups via other inter-group alarms, and fire alarms are output all at once.

Subsequently, when the adapter control unit 32 of the first transfer adapter 14 determines the operation of the test switch 46 in step S28, the adapter control unit 32 proceeds to step S29 to perform test control.

(Test control of transfer adapter)
FIG. 10 is a flowchart showing the details of the test control in step S29 of FIG. As shown in FIG. 10, when the adapter control unit 32 of the first transfer adapter 14 determines the test instruction in which the self-group is designated as the test destination in step S31 with respect to the operation of the test switch 46, the adapter control unit 32 proceeds to step S32, for example. Taking the intergroup transfer device 12-12 of FIG. 1 as an example, as shown in the self-group designation column of the first transfer adapter 14 of FIG. 4B, the test destination designation information in which the self-group G1 is designated is specified. Send the test signal set to. Subsequently, the adapter control unit 32 of the first transfer adapter 14 proceeds to step S33 to perform a self-group test response process.
