Description

The present invention outputs a disaster prevention alarm such as an earthquake or tsunami transmitted from a local disaster prevention radio equipment such as a municipal disaster prevention radio equipment using an alarm device that detects an alarm such as a fire or gas leak installed indoors. It relates to the disaster prevention alarm linkage system.

  2. Description of the Related Art Conventionally, alarm devices that detect and warn of abnormalities such as fires and gas leaks in houses have become widespread. Of these, residential disaster alarms are referred to as residential alarms.

  For example, in such a house alarm, a sensor unit and an alarm unit are integrally provided in the house alarm, and when a fire is detected from a fire detection signal by the sensor unit, a fire alarm of a predetermined pattern is output from the alarm unit. Because it is possible to monitor and alarm with a resident alarm alone without the need for dedicated receiving equipment, etc., it is easy to install and inexpensive, and it has become widespread due to the mandatory installation in ordinary houses. doing.

  In addition, by communicating between multiple home alarms, we propose a linked alarm system that outputs fire alarms in conjunction with other home alarms when any home alarm outputs a fire alarm. Has been put to practical use.

  In such an interlocking alarm system, when a fire is detected by a home alarm, the home alarm that detects the fire is a fire alarm sound of a predetermined pattern including a message, such as “Woo Woo Fire Alarm”. On the other hand, for example, a fire alarm sound such as “Please check if another fire alarm has been activated.” .

  On the other hand, municipalities have installed and operated municipal disaster prevention radio equipment for disaster prevention administration. Municipal disaster prevention radio equipment consists of a master station, relay station, and slave station equipped with a console, and a slave station that notifies the alarm from a loudspeaker is installed in the slave station and installed indoors if necessary. A door-to-door receiver is also provided to notify the alarm.

  In such a municipal disaster prevention radio equipment, if an emergency earthquake warning is received or a tsunami warning is issued, the person in charge of disaster prevention administration operates the corresponding alarm operation button on the console to modulate the audio signal. The emergency information signal is transmitted from the master station, and the emergency information signal is received via the relay station or directly at the loudspeaker station installed outdoors and the door-to-door receiver installed in the residence. The alarm is sent from the loudspeaker to the area in charge at the set volume, or the alarm is output from the door-to-door receiver.

In recent years, due to national measures, the conventional analog system has been abandoned and a digital system has been promoted. In the near future, digital systems will be introduced in all municipalities.

JP 2007-094719 A Utility Model Registration No. 3154579 JP 2009-244937 A JP 2009-284237 A Radio industry "City / town / town digital broadcast communication system standard ARIB STD-T86 2.0 edition", November 30, 2005 2.0 revision [May 30, 2011 search], Internet (URL: (www.arib.or.jp/tyosakenkyu/kikaku_tushin/tsushin_kikaku_number.html)

  However, in such conventional municipal disaster prevention radio equipment, the emergency information signal transmitted from the master station is received by a loudspeaker station installed outdoors, and an alarm is sent from the loudspeaker to the jurisdiction at a loud volume. However, when alarms are output simultaneously from multiple loudspeaker stations, there is a problem in that it is difficult to hear the alarm content due to multiple sounds interfering in places where both sounds reach, and the deadline. However, there is still a problem that it is difficult to hear an outdoor alarm from a loudspeaker station when indoors.

  In order to solve this problem, it is only necessary to install a dedicated individual receiver in every dwelling unit. However, the installation cost increases significantly, and it takes time and labor for maintenance, which is not practical.

  In addition, when a door-to-door receiver is installed in a dwelling unit, alarms such as earthquake early warnings and tsunami warnings can be heard only within the range where the sound from the door-to-door receiver can be heard. There are problems such as high cost and installation space must be secured in various places.

  Also, the door-to-door receiver may not be able to receive radio waves with sufficient intensity in some rooms due to poor radio wave conditions, and may not function effectively even if installed in such a place.

The present invention receives a signal transmitted from a local disaster prevention radio facility such as a municipal disaster prevention radio facility in cooperation with an alarm device, does not require a door-to-door receiver, and is a place where the radio wave reception environment is not good. The purpose is to provide a disaster prevention alarm linkage system that makes it possible to reliably know disaster prevention information such as the occurrence of an earthquake or the arrival of a tsunami.

[Configuration of disaster prevention alarm linkage system]
(System overview)
FIG. 1 is an explanatory diagram showing an outline of a disaster prevention alarm cooperation system according to the present invention in which a municipal disaster prevention radio facility is taken as an example of a regional disaster prevention radio facility, and this is combined with a residence guard.

  In FIG. 1, a disaster prevention alarm linkage system according to the present invention includes a municipality disaster prevention radio equipment 10 known as a municipal digital broadcast communication system that covers a target area such as a municipality as a service area, and a house built in the same target area. 24 is configured by an alarm system including a wireless residence alarm device (residential fire alarm device) 100 that detects and interlocks with a fire.

  Here, the municipal disaster prevention radio equipment 10 transmits, receives and relays signals wirelessly in accordance with a predetermined first wireless communication protocol, while the home alarm device 100 transmits an interlocking signal in accordance with a different predetermined second wireless communication protocol. Executes a linked alarm by receiving and relaying. The first wireless communication protocol corresponds to the first communication protocol in the claims, and the second wireless communication protocol corresponds to the second communication protocol in the claims.

  In addition, the house alarm 100 forms a unique group for each house 24 installed, and the interlocking signal transmitted from the house alarm 100 includes a predetermined group code, and the interlocking signal is received. When the group code obtained by decoding the interlocking signal matches the group code to which the self belongs, the effective reception of the interlocking signal is detected and an interlocking alarm is issued.

  The municipal disaster prevention radio equipment 10 is configured by appropriately arranging a master station 12, a console 14, a loudspeaker slave station 16 equipped with a loudspeaker 18, a door-to-door receiver 20, a relay station 22, and the like. The master station 12 is the highest station provided in the city hall, village hall, etc., and performs two-way communication with the relay station 22 and the loudspeaker slave station 18 and performs downstream communication with the individual receiver 14 in the vicinity of the master station 12. Do. The relay station 22 is installed, for example, at the summit in consideration of the area where radio waves do not reach, and performs bidirectional relay between the master station 22 and the loudspeaker slave station 22 and relay from the master station 12 to the individual receiver 20.

  FIG. 1 shows a case where the door-to-door receiver 20 is provided in a place other than the house 24, for example, a public facility such as a public hall, and can be provided in the house 24 as necessary. In the form, since the disaster prevention information is notified and output using the residence guard 100 provided in the house 24, the residence guard 100 will cover a part of the functions of the door-to-door receiver 20, and thus the residence unit. It is not always necessary to install the receiver 20 in the house 24. The house 24 includes dwelling units and houses.

  In addition, the municipal disaster prevention radio equipment 10 is connected to a retransmitting slave station and an operation console 14 for relaying radio waves in a limited area such as a valley where radio wave propagation is poor, and is connected to a master station from a place other than the master station 12 by a wired connection. A remote control station or the like is provided as needed to control the terminal 12 and perform a selective call of a slave station or a loudspeaker report. In FIG. 1, the case where one relay station 22 is arranged is taken as an example. However, by installing a plurality of relay stations 22 and retransmission slave stations as necessary, a plurality of master stations 12 and a plurality of relay stations 22 are arranged. A disaster prevention wireless network is constructed in which the door-to-door receiver 20 and the loudspeaker slave station 16 are connected by a wireless line.

  The communication system of the municipal disaster prevention radio communication facility 10 is a TDMA (Time Division Multiple Access) -TDD (Multi-channel) by dividing one radio carrier into frames and dividing the frames into slots corresponding to the number of multiplexing. Time division duplex (Time Division Duplex) system. Specifically, it complies with the standard of radio section interface of digital broadcast communication system for disaster prevention administration by TDMA-TDD system of municipal digital disaster prevention radio communication system in 60MHz band stipulated in Article 58-2-12 of Radio Equipment Regulations .

  FIG. 2 is an explanatory diagram showing a frame configuration in the communication system of the municipal disaster prevention radio equipment 10 (frame configuration in the TDMA radio system). One frame consists of six slots # 0 to # 5, and slot # 0 and slot # 3 are signaling channels SCCH that are point-to-point bidirectional channels for transferring information between the master station and the slave stations. Slot # 1, slot # 2, slot # 4, and slot # 5 are traffic channels TCH that the user uses exclusively for communication. Slot # 0 to slot # 2 are basically slots in the downlink direction, and slot # 3 to slot # 3 are basically slots in the uplink direction.

  Referring to FIG. 1 again, in this embodiment, the relay adapter 100 is installed outdoors in each service area obtained by dividing the service area of the municipal disaster prevention radio equipment according to the local situation. For example, it is installed on a column where the loudspeaker slave station 16 is installed. The relay adapter 200 receives a notification signal in accordance with the first wireless communication protocol transmitted from the master station 12 or transmitted via the relay station 22, and sends the notification signal to the second alarm signal on the side of the home alarm device 100. It is converted into an interlocking signal according to the wireless communication protocol and transmitted.

  The interlocking signal transmitted from the relay adapter 200 includes a common group code, and when the home alarm device 100 installed in each house 24 receives and decodes the interlocking signal and detects the common group code, Even if the group code does not match, the interlock signal from the relay adapter 200 is effectively received and the notification output is performed. Here, the interlock signal set with the common group code means an interlock signal without group designation in the claims.

  The communicable area that is the service area of the relay adapter 200 is an area that includes the home guard 100 that is installed in a house in the area where the sound from the loudspeaker 18 of the loudspeaker 16 reaches, for example. For this reason, the relay adapter 200 is installed so as to cover the required service area as a communicable area depending on the transmission power, the direction of the antenna, and the like.

  If one relay adapter 200 cannot cover the required service area, a plurality of relay adapters 200 are installed as necessary. Further, by installing the relay adapter 200 in the vicinity of the loudspeaker slave station 16, for example, on a support column, the AC power supply of the loudspeaker slave station 16 can be used as it is as an AC power source for the relay adapter 200 installed outdoors. Since it is not necessary to secure a dedicated outdoor AC power source for 200, the equipment configuration can be simplified and the installation cost can be reduced.

  FIG. 3 is an explanatory diagram showing an example of distribution of communication service areas determined by the relay adapter in the embodiment of FIG. Here, the service area is divided into service areas or service areas.

  In FIG. 3, in the service area (communicable area) of the municipal disaster prevention radio equipment by the master station 12 and the relay station 22, the relay adapter 200 is installed outdoors, for example, in service areas A1 to A4. The adapter 200 sets a communicable area that covers the home alarm device 100 installed inside the dwelling unit existing in each service area A1 to A4.

  In this way, by installing the relay adapter 200 outdoors corresponding to the service areas A1 to A4, the master station 12 selects the relay adapter 200 as a transmission destination, thereby arbitrarily selecting the service areas A1 to A4 to send the notification signal. Select one or a plurality of service areas as required, and output disaster prevention information based on emergency calls from the home guard 100 installed indoors in the selected service area. Can do.

  For example, in the case of emergency earthquake warning or emergency alert, the relay adapter 200 of all regions is selected by the operation at the master station 12 and an emergency alert information notification signal is transmitted. In the case of a tsunami alert, the area facing the coastline is selected. The relay adapter 200 is selected and an emergency alert information notification signal is transmitted.

When the input of the instruction signal is detected, the corresponding disaster prevention data is acquired from a database (not shown) and output to the wireless communication unit 32, and the transmission data is transmitted in a predetermined slot.

  Further, the control unit 26 decodes the received data taken out from the slot received and demodulated by the wireless communication unit 32, and outputs it to the display unit 38 of the console 14, for example, for display. The voice input unit 28 voice-codes the voice signal input from the broadcasting microphone 40, outputs it as transmission data to the wireless communication unit 32, arranges it in a predetermined slot, and transmits it. The telephone control unit 30 controls a call connection between a slave telephone provided in the loudspeaker slave station 16 or the like and a master telephone 42 provided on the console 14.

  The wireless communication unit 32 repeatedly performs the transmission operation for modulating and transmitting the uplink slot of the frame shown in FIG. 2 and the reception operation for receiving and demodulating the downlink slot. In the wireless communication according to the first wireless communication protocol by the wireless communication unit 32, the wireless frequency band is set to 60 MHz (54 to 70 MHz), and the channel interval is set to 15 KHz. The antenna transmission power is 10 W or less, the modulation method is 16QAM (16-value orthogonal modulation method), the downlink from the master station 12 to the slave station and the uplink from the slave station to the master station 12 are used. Enables communication, one-way communication, duplex, and half-duplex communication.

  The communication from the master station 12 to the slave station includes communication of data, images, facsimiles, character information, and the like that are voice communication and non-voice communication. In addition, communication modes include door-to-door communication that communicates with a specific slave station, group communication that communicates with a group consisting of a plurality of slave stations, and batch communication that includes all standby slave stations. There are communication control that enables communication control such as information communication, emergency control, call control of a slave station at the master station 12 and call time limit.

  In the present embodiment, an emergency earthquake warning report signal, a tsunami warning report signal, and an emergency alert report signal are transmitted from the master station 10 according to the first wireless communication protocol, and this is handled by the relay adapter 200 installed outdoors. 2) Converted into an earthquake early warning interlocking signal, tsunami warning interlocking signal, and emergency alert interlocking signal in accordance with the wireless communication protocol, and the residential alarm device 100 installed indoors is an emergency earthquake early warning interlocking signal, tsunami warning interlocking signal or emergency alert interlocking When effective reception of a signal is detected, disaster prevention information corresponding to each is notified and output.

  For example, when a person in charge of disaster prevention at the master station 10 receives an emergency information broadcast by a television receiver and determines the necessity of emergency notification, an emergency earthquake warning, tsunami warning, or emergency alert notification button provided on the console 14 is provided. By operating the selection button of the notification area and the like, an emergency earthquake warning report signal, tsunami warning report signal or emergency alert report signal is transmitted to the slave station side by broadcast communication or door-to-door communication.

  Emergency information broadcasts received by a television receiver, FM receiver, or AM receiver include emergency earthquake warning (EEW) and emergency warning system (EWS). The earthquake early warning is a warning issued by the Japan Meteorological Agency with an estimated maximum seismic intensity of less than 5 for the general public, and warns that there is a possibility of serious disasters due to earthquake motion to areas where strong shaking is expected Broadcast. The earthquake early warning is, for example, “(twice chime sound) emergency earthquake early warning. Beware of strong shaking.

  Emergency warning broadcasting is an alarm that is issued when a large-scale disaster such as an earthquake occurs, or when a tsunami warning is announced, and automatically switches on a standby television or radio receiver. The first type start signal, the second type start signal, and the end signal are used for the start and end of the emergency warning broadcast. The first type start signal is transmitted when a warning declaration of the Tokai earthquake is announced, or when an evacuation instruction is issued from the governor or the head of the local government, and automatically turns on the receiver. Also. The type 2 start signal is sent only when a tsunami warning is announced, and the same automatically turns on the receiver. The end signal is transmitted a predetermined time after the transmission of the first type or second type start signal, and automatically turns off the receiver. In addition, a test signal is transmitted at a predetermined time, for example, once a month to check the operation of the receiver. This test signal is the same as the end signal, and if only the end signal is received, the receiver operates normally. Check if it works.

  In this case, if the person in charge receives emergency earthquake warnings on a television etc. and performs a reporting operation, there is a risk that the emergency station will not be able to report before the strong shaking caused by the earthquake. The earthquake early warning receiver 44 is provided, the first chime sound in the emergency earthquake early warning is detected, the emergency earthquake early warning detection signal is output to the control unit 26 of the master station 12, and the emergency earthquake early warning report signal is automatically sent to the slave station side.

For such notification by automatic reception, the first type start signal or the second type start signal in emergency alert broadcasting is detected and output to the master station 12, and the emergency alert report signal and the tsunami alert report signal are automatically transmitted to the slave station side. You may make it transmit.

  In the following description, when the earthquake early warning, the tsunami warning and the emergency warning are collectively expressed, it is called emergency information, and the signals representing these transmitted from the master station 10 are the emergency earthquake early warning signal and the tsunami warning notification. Signals and emergency alert notification signals, and collectively referred to as emergency information notification signals.

  In addition, a signal transmitted / received between the residential alarms 100 in the alarm system is referred to as an “interlocking signal”, and the interlocking signal includes a fire interlocking signal, a fire recovery interlocking signal, an alarm stop interlocking signal, and a failure interlocking signal. When the relay adapter 200 receives an emergency earthquake warning signal, a tsunami warning signal, and an emergency warning signal according to the first wireless communication protocol from the master station 10, the relay adapter 200 follows the second wireless communication protocol based on the notification signal. It is converted into an interlocking signal including a common group code (an interlocking signal without group designation) and relayed, and the interlocking signals in this case are called an emergency earthquake warning interlocking signal, a tsunami warning interlocking signal, and an emergency alert interlocking signal. Further, when the home alarm device 100 receives an emergency earthquake warning interlocking signal, a tsunami warning interlocking signal, and an emergency alert interlocking signal from the relay adapter 200 or another housing alarm, it is assigned to the interlocking group to which it belongs based on the interlocking signal. An interlocking signal including the group code is generated and relay-transmitted to the other residential alarm.

In addition to this, character data, FAX image data, and the like are demodulated as necessary and output to an externally connected device. You may do it.

(Overview of the home alarm 100)
Referring again to FIG. 1, the home alarm device 100 installed in the house 24 has a function of transmitting and receiving interlocking signals to and from each other according to the second wireless communication protocol. The presence or absence is monitored.

  Now, if a fire occurs in a certain house 24, for example, the house alarm device 100 detects the fire and starts an alarm. Detecting this fire and initiating an alarm is referred to as “reporting” at the home alarm.

  When the home alarm device 100 issues a report, the home alarm device 100 functions as an interlocking source, and wirelessly transmits a fire interlocking signal to another home alarm device as an interlocking destination according to a predetermined second wireless communication protocol. When the other house alarm device effectively receives the fire interlock signal from the interlocking source house alarm device 100, the alarm operation as the interlock destination is performed by the alarm sound and the alarm display.

  Here, when the group code included in the received interlocking signal matches the group code stored in the memory and the signal content is normally recognized, the home alarm device 100 confirms that the interlocking signal has been effectively received. I try to detect it. Furthermore, the resident guard 100 that has received the interlock signal effectively performs relay transmission of the interlock signal as necessary. The group code is set as a unique code for each alarm system, and each residential alarm can identify and process only the interlocking signal related to the alarm system to which it belongs.

  As an alarm operation of the home alarm 100 that is the linkage source, for example, a fire alarm sound is output by a voice message such as “Please confirm that the Woo Woo fire alarm has been activated”. On the other hand, the linked home alarm device 100 outputs a fire alarm sound by a voice message such as “Please check if another fire alarm is activated”.

  Moreover, as an alarm display accompanying the fire alarm of the house alarm device 100 which became the interlocking | linkage origin, LED is lighted, for example. On the other hand, in the interlocking destination home alarm device 100, the LED blinks. As a result, the alarm display by the LED in the interlock source alarm and the interlock destination alarm can be distinguished.

  It should be noted that the interlocking source LED may be blinking and the interlocking destination LED may be lit, or the same LED may be blinking or blinking or lit for both the interlocking source alarm and the interlocking destination alarm. Further, for example, a red LED and a yellow LED may be provided, and the two-color display may be performed such that the interlocking source drives the red LED and the interlocking destination drives the yellow LED. Of course, it is also possible to employ a two-color LED that can emit both red and yellow by integrating two LEDs.

  When the alarm stop switch is operated in a state in which the house alarm 100 is emitting an alarm sound, the alarm sound and the alarm display stop process are performed. At this time, for example, when an alarm stop operation is performed at the interlocking source residence police 100, the alarms of all the residence guards 100 are stopped, and the alert stop operation is performed at the interlocking destination residence guard 100. In such a case, the alarm of the interlocking home mortgage 100 is not stopped, but the alarm of the interlocking destination sill 100 is stopped so that the location of the fire is known.

  In the case of Japan, transmission / reception by the home security device 100 using the predetermined second wireless communication protocol is, for example, STD-30 (a low-power security system wireless station) known as a standard for a specific low-power wireless station in the 400 MHz band. It conforms to STD-T67 (standard specification for radio equipment for specific low power radio station telemeter, telecontrol and data transmission). Of course, when used outside Japan, the content conforms to the standard of the assigned radio station in that region. The transmission power of the residential police device 10 compliant with the specified low-power radio station is 10 mW or less for STD-30, 10 mW or less or 1 mW or less for STD-T67, and the line-of-sight communication distance is approximately 100 meters or more. It becomes.

  The home guard 100 installed indoors in the house 24 is an emergency information link signal including a common group code according to the second wireless communication protocol transmitted after protocol conversion by the relay adapter 200 installed outdoors. When an earthquake early warning interlocking signal, a tsunami warning interlocking signal, or an emergency alert interlocking signal is received and effective reception is detected by decoding it, predetermined disaster prevention information is notified and output accordingly.

  When the home alarm device 100 detects the effective reception of the earthquake early warning interlocking signal from the relay adapter 200, the disaster prevention information corresponding to the emergency earthquake early warning is, for example, “PPP emergency earthquake early warning. Be wary of strong shaking.” The voice message is repeatedly notified and output, and the LED is turned on, for example.

  In addition, when the home alarm device 100-1 detects the effective reception of the tsunami warning interlocking signal from the relay adapter 200, the disaster prevention information corresponding to the tsunami warning is issued, for example, “Phi Tsunami warning has been issued. Please evacuate to the hill. "The voice message such as" Please evacuate. "

  In addition, when the home alarm device 100 detects the effective reception of the emergency alert interlocking signal from the relay adapter 200, it repeatedly reports a voice message such as “Peep emergency alert has been issued” as disaster prevention information corresponding to the emergency alert. For example, the LED is turned on while outputting.

  Each disaster prevention information notified and output from the home alarm device 100 stops, for example, after a predetermined time has elapsed or after a predetermined number of notifications.

  Further, the home alarm device 100 receives an emergency earthquake warning interlocking signal, a tsunami warning interlocking signal, or an emergency alert interlocking signal, which is an emergency information interlocking signal including a common group code according to the second wireless communication protocol, from the relay adapter 200. When an effective reception is detected by decoding, an earthquake early warning interlocking signal, tsunami warning interlocking signal or emergency alert interlocking signal is generated in accordance with the second wireless communication protocol including the group code of the interlocking group to which the self belongs. Then, the corresponding disaster prevention information is transmitted to the other home alarm devices 100 belonging to the same group and the corresponding disaster prevention information is output.

  Here, when the communication paths according to each wireless communication protocol in FIG. 1 are arranged, between the master station 12 and the relay station 22 in the town and village disaster prevention radio equipment 10, the individual receiver 20 of the loudspeaker slave station 16, and the residence guard 100-1. And the route between the relay receiver 22 and the individual receiver 20 of the loudspeaker slave station 16 and the relay adapter 200 are the first wireless communication protocol route 11a, and the relay adapter 200 and the home guard 100 of each house 24 are connected to each other. The route between them is the second wireless communication protocol route 11b.

(Appearance of the home guard 100)

  In FIG. 7, the housing of the residential alarm device 100 according to the present embodiment includes a cover 112 and a main body 114. A protrusion is provided at the center of the cover 112, a plurality of smoke inlets are opened around the protrusion, and a smoke detector 116 is disposed in the inside thereof, so that smoke accompanying a fire flows into the smoke detector 116. When a predetermined concentration is reached, a fire is detected by an alarm control unit described later. As the smoke detector 116, for example, a known scattered light smoke detector mechanism can be applied.

  An acoustic hole 118 is provided on the lower left side of the cover 112, and a buzzer and a speaker are incorporated behind this so that an alarm sound and a voice message can be output. An alarm stop switch 120 is provided below the cover 112.

  The alarm stop switch 120 is configured to press a built-in push switch (not shown) when a switch cover formed of a translucent member is pressed. An LED 122 that displays an alarm or the like is disposed near the push switch inside the switch cover.

  The alarm stop switch 120 also functions as an inspection switch that instructs the self-inspection of the function of the home alarm 100 from the outside. For example, when the alarm stop switch 120 is operated during the fire alarm output, the fire alarm is stopped, and when the alarm stop switch 20 is operated in a normal state, a self-inspection is performed for a predetermined function, and the result is obtained by the LED 122 or the speaker. Is notified. Here, the normal state refers to a state where at least a fire alarm is being output or a failure alarm is not being output.

  Further, a mounting hook 115 having an insertion hole in the substantially central portion is provided at the upper part on the back side of the main body 114, and a screw or the like is screwed into the wall surface of the room to be installed, and the insertion hook 115 is hooked through the screw. Thus, the residential alarm 100 can be fixedly installed on the wall surface in a so-called wall-hanging manner.

(Configuration of relay adapter 200)
FIG. 8 is a block diagram showing an embodiment of a relay adapter and a residential alarm provided in the disaster prevention alarm cooperation system of FIG. This is an example, and the separation and integration of each function can be performed arbitrarily. Further, any part or all of each function may be executed by software (program) or may be executed by hardware.

  In FIG. 8, the relay adapter 200 will be described first. The relay adapter 200 includes a processor 202, and the processor 202 is connected to an antenna 206 that receives a notification signal in accordance with the first wireless communication protocol transmitted from the master station 12 of the municipal disaster prevention radio equipment 11. A first wireless communication unit 204 provided with a circuit 216; a second wireless communication unit 208 provided with a second transmission circuit 218 connected to an antenna 210 for transmitting a notification signal in accordance with the second wireless communication protocol to the home alarm device 100; A power source circuit unit 212 that generates a DC power source from AC 100 V and supplies it to each unit and a standby power source unit 214 using a secondary battery such as a battery are provided.

  The first reception circuit 216 of the first wireless communication unit 204 is transmitted from the master station 12 or the relay station 22 of the municipal disaster prevention radio equipment 11, for example, a first wireless communication protocol compliant with a municipal digital disaster prevention radio communication system standard of 60 MHz band. In accordance with the information, an emergency earthquake warning report signal, tsunami warning report signal or emergency warning report signal is received and demodulated and output to the processor 202.

  The processor 202 is provided with the function of the relay control unit 220. The relay control unit 220 inputs and decodes the earthquake early warning report signal, tsunami warning report signal or emergency alert report signal received and demodulated via the antenna 206 and the first receiving circuit 214 of the first wireless communication unit 204, and the effective When receiving is detected, an earthquake early warning interlocking signal according to the second wireless communication protocol conforming to the standard of a specific low-power radio station in the 400 MHz band, for example, having the same format configuration as the interlocking signal shown in FIG. Then, a tsunami warning interlocking signal or an emergency alert interlocking signal is generated and output to the second wireless communication unit 208.

  Here, the group code included in the interlocking signal to be transmitted from the relay adapter 200 according to the second wireless communication protocol is set to a common group code that enables effective reception by all residential alarms, so-called no group designation. It is different from the interlocking signal transmitted / received between the mortgages that set the unique group code in that the interlocking signal is used. In addition, as a group code included in the interlocking signal transmitted from the relay adapter 200 according to the second wireless communication protocol, a unique group code is set by an operation on the master station 12 side, so that a residence guard provided in a specific dwelling unit is set. It is also possible to use an interlocking signal that enables effective reception by a device, and to output information corresponding to the interlocking signal from a residence guard provided in a specific dwelling unit.

  The second transmission circuit 218 of the second wireless communication unit 208 receives the emergency earthquake warning interlocking signal, the tsunami warning interlocking signal, or the emergency alert interlocking signal input from the processor 202 via the antenna 210 according to the second wireless communication protocol. Send to. The transmission power from the antenna 210 by the second transmission circuit 218 is, for example, 1 W or less so that the radio wave can sufficiently reach the residential alarm 100 installed in the house in the entire service area under the jurisdiction of the relay adapter 200 installed outdoors. A relatively large transmission power is set. Since the transmission power of 1W or less is out of the standard specification of a specific low-power radio station in the 400MHz band, which has a transmission power of 10mW or less or 1mW or less, it is necessary to apply for a license for a radio station for its installation. Measures such as are necessary.

(Configuration of the home alarm 100)
Next, the house alarm device 100 will be described. The home alarm device 100 includes a processor 124 known as a one-chip CPU, and a second wireless communication unit 130, a memory 132, and the like that perform transmission and reception of interlocking signals in accordance with a predetermined second wireless communication protocol. A sensor unit 134, a notification unit 136, an operation unit 138, and a battery power supply 140 are provided, and the battery power supply 140 supplies power to necessary units.

  The second wireless communication unit 130 includes a second transmission circuit 146 and a second reception circuit 148 to which an antenna 131 is connected. The second wireless communication unit 130 is in communication with other dwelling devices 100 according to the second wireless communication protocol compliant with the standard of a specific low power wireless station in the 400 MHz band, for example, fire, fire recovery, alarm stop, failure, etc. Are transmitted and received, and the earthquake early warning interlocking signal, tsunami warning interlocking signal or emergency alert interlocking signal transmitted from the relay adapter 200 installed outdoors is received.

  The transmission of the interlocking signal by the second wireless communication protocol in the second transmission circuit 146 of the second wireless communication unit 130 is performed by performing an operation of transmitting the interlocking signal for a predetermined time T1, for example, T1 = 3 seconds, for a predetermined time T2, for example, T2. For example, four times with a pause of 2 seconds. This T1 = 3-second transmission and T = 2-second pause comply with the standard of a specific low-power radio station. Further, in the transmission operation of T1 = 3 seconds, for example, 2.8 seconds from the beginning of the transmission operation is a dummy signal transmission, and the interlocking signal is repeatedly transmitted in the remaining 0.2 seconds. The transmission operation of the second transmission circuit 146 is the same for the second transmission circuit 218 provided in the relay adapter 200.

  In addition, reception by the second wireless communication protocol in the second reception circuit 148 of the second wireless communication unit 130 intermittently receives interlocking signals from other residential alarm devices belonging to the same group as the residential alarm device 100 and the relay adapter 200. . In the intermittent reception, the reception operation is repeated for a predetermined period T3, for example, every T3 = 7 seconds, for a receivable time T4, for example, T4 = 100 milliseconds, and during the receivable time T4, the transmission dummy signal is carrier sensed. When the signal is detected, the signal is switched to continuous reception for a predetermined time and the interlocking signal or the cooperation signal following the dummy signal is received.

  Here, the signal received by the second wireless communication unit 130 is decoded by the alarm control unit 160 provided in the processor 124. Hereinafter, it may be called reception including even this decoding. In particular, when the signal is determined to be valid as a result of decoding, it is called effective reception. “Detecting reception” in the claims means “effective reception” or “detecting effective reception”.

  Further, in the second wireless communication protocol of the second wireless communication unit 130, when the resident guard 100 itself detects a fire or an event other than a fire and transmits an interlock signal, or receives an emergency information interlock signal from the relay adapter 200 Then, when an emergency information interlocking signal based on this is generated and transmitted to another residence guard, it belongs to the same group as the residence guard 100, and the interlocking signal is normal from the other residence guard that has received it. It is monitored whether or not an acknowledgment signal (hereinafter referred to as “ACK signal”) indicating that it has been received is effectively received.

  In the case where an ACK signal that is not received is detected among other mortgages, the ward 100 transmits a relay request presence interlock signal to the other arriving units that have received the ACK signal, and there is a relay request. A relay signal with a relay request is relay-transmitted from the home alarm device that has received the interlock signal to the home alarm device that has not yet responded to the AKC signal. An ACK signal that has not received an AKC signal that has received a relay signal with a relay request returns an ACK signal in response to the relay signal with a relay request. Then, it is received by the interlocking home security device 100. Accordingly, if there is a residence guard that does not receive the ACK signal, it is determined as a communication failure or the like, and a predetermined notification process, a linkage process, a linkage process described later, and the like are performed.

  The above-described relay function is useful when three or more home alarm devices are installed in one interlocking group, for example, the house 24. In the example of FIG. 1, since only two residence guards 100 are installed in the house 24, the residence guard 100 receives an ACK signal (reply) from another residence guard in response to the interlocking signal transmitted by itself. If not, it is determined that there is a communication failure or the like, and a predetermined notification process or a cooperation process described later is performed.

  As shown in FIG. 9, the interlock signal 150 transmitted and received by the second wireless communication unit 130 of the second wireless communication unit 130 is configured as a format including a serial number 152, a transmission source identification code 154, a group code 155, and an event code 156. ing. The serial number 152 is a code that is generated independently for each residential alarm, and is a serial number that indicates the generation order or transmission order of the interlocking signal 150. Based on this, management such as prohibition of re-relay can be performed. The transmission source identification code 154 is, for example, a serial number of a residential police device that identifies each residential security device, and the group code 155 is linked to each other within the group of residential security devices 100 installed in the house 24 as shown in FIG. It is the code | symbol for comprising the interlocking group to perform.

  Moreover, in this embodiment, the interlocking signal according to the second wireless communication protocol transmitted from the relay adapter 200 can be effectively received by all the residential alarm devices 100 installed in the houses 24 in the target area. Since it is necessary, a common group code common to all groups is set as the group code 155. This common group code is a code meaning that there is no group designation because it is effectively received by all the residential alarm devices 100 constituting different interlocking groups.

The event code 156 is a code representing the content of an event such as a fire. In the present embodiment, a 4-bit code is used. For example, 0001 = fire 0010 = ACK
0011 = Alarm stop 0100 = Recovery 0101 = Sensor failure 0110 = Low battery failure.

  Note that the above-described code indicating “relay request is present” is omitted here, but it can be added to the event code by increasing the number of bits.

Further, in the present embodiment, an emergency earthquake warning report signal, a tsunami warning report signal and a tsunami warning report signal transmitted from the master station 12 of the municipal disaster prevention radio equipment 10 received through the second radio communication unit 130 via the protocol conversion of the relay adapter 200, and As an event code corresponding to the interlocking signal based on the emergency alert notification signal, that is, the earthquake early warning interlocking signal, the tsunami alert interlocking signal and the emergency alert interlocking signal,
0111 = Earthquake Early Warning 1000 = Tsunami Warning 1001 = Emergency warning is added.

  It should be noted that both the identification code indicating the source (interlocking source) residence guard and the identification code of the residence policer performing the relay are added to the interlocking signal relayed by the residence guard. Further, an identification code for designating a transmission destination may be added.

  Further, although the above-described code indicating “relay request is present” is omitted here, for example, it can be added to the event code by assigning it to “1111”, for example. Further, for example, “0000” may be assigned for periodic communication confirmation. Of course, more event codes can be assigned by increasing the number of bits.

  The sensor unit 134 is provided with a smoke detection unit 116 that detects smoke based on, for example, a scattered light type smoke detection principle and outputs a smoke detection signal corresponding to the smoke density.

  The notification unit 136 is provided with a speaker 158 that is an acoustic output device that outputs an alarm sound and the like, and an LED 122 that performs alarm display and the like along with respective drive circuits (not shown). Under the control of the alarm control unit 160, the speaker 158 outputs a voice message, an alarm sound, or the like based on various data stored in the memory 132 or the like by the residential alarm 100. The LED 122 notifies an abnormality or other event such as a fire by display by blinking, blinking, or lighting.

  The operation unit 138 is provided with an alarm stop switch 120. The alarm stop switch 120 functions as an alarm stop switch only when a warning sound of a fire or failure is output from the notification unit 136 by the speaker 158 or when an alarm display is performed by the LED 122. For example, if the alarm stop switch 120 is operated during the alarm indicating the interlock source, the alarm sound and the alarm display are stopped, while if the alarm stop switch 120 is operated during the alarm indicating the interlock destination, the alarm sound is stopped. Alarm stop processing is performed such that the alarm display is stopped or stopped after a predetermined time.

  On the other hand, in the normal monitoring state where the alarm indicating the interlocking source or the interlocking destination is not performed, the alarm stop switch 120 functions as an inspection switch. When the alarm stop switch 1 is operated in this state, a predetermined self-inspection operation is performed. And a voice message indicating the inspection result is output from the notification unit 136.

  The memory 132 stores a serial number 152, an identification code 154, a group code 155, and the like used for generating the interlocking signal.

  The battery power supply 140 uses, for example, a lithium battery or an alkaline battery having a predetermined number of cells, and supplies power to necessary parts. As the battery capacity, for example, a lifetime of 10 years is guaranteed by reducing the power consumption of the entire circuit unit in the home alarm device 100.

  The processor 124 is provided with the function of the alarm control unit 160 as a function realized by executing the program.

  The alarm control unit 160 includes a presence / absence of a fire based on a smoke detection signal from the smoke detection unit 116 provided in the sensor unit 134, presence / absence of an alarm stop instruction input by the operation unit 138, presence / absence of an inspection instruction, presence / absence of mode setting, The detection signal from the smoke detection unit 116 provided in the unit 134 is detected to detect an event such as the presence or absence of a fire recovery, a sensor failure or a failure, or a low battery failure or the like that the fire detection state is resolved.

  Also, the alarm control unit 160 detects information such as the presence / absence of the interlocking signal effective reception and the interlocking contents obtained as a result of decoding the interlocking signal from the other resident alarm and the relay adapter 200 via the second receiving circuit 148. .

  In addition, when the alarm control unit 160 detects the presence of a fire based on the smoke detection signal of the smoke detector unit 116 provided in the sensor unit 134, a fire alarm sound such as “ "Woo Woo is a fire. Please confirm that it is a fire." The voice message of "Please confirm" is repeatedly output, the LED 122 is turned on and the fire alarm display indicating the interlocking source is performed. The second transmission circuit 146 is controlled to transmit a fire-linked signal according to a predetermined second wireless communication protocol to the other home alarm device 100-2.

  When the alarm control unit 160 detects the effective reception of the fire-linked signal transmitted or relayed from the other residential alarm device 100-2 via the antenna 131 and the second receiving circuit 148 of the second wireless communication unit 130 In addition, as an alarm indicating the link destination, control is performed to repeatedly output a sound message such as “Please confirm that another fire alarm has been activated” from the speaker 158 of the notification unit 136, and the LED 122 blinks, for example. Control to display an alarm indicating the interlocking destination. Furthermore, the second transmission circuit 146 is controlled to transmit an ACK signal as a response signal (reply) accompanying the reception of the fire interlock signal from the interlock source.

  When the alarm control unit 160 detects a fire recovery during the output of the fire alarm sound indicating the interlock source, the alarm control unit 160 controls the notification unit 136 to perform the fire alarm operation by the alarm sound output from the speaker 158 and the alarm display output of the LED 122. While stopping, it performs control which transmits the fire recovery interlocking signal from the 2nd transmission circuit 148 of the 2nd radio | wireless communication part 130 toward the other home alarm devices 100 via the antenna 131. FIG.

  When the alarm control unit 160 detects the operation of its own alarm stop switch 120 while outputting the fire alarm sound indicating the interlock source, the alarm control unit 160 controls the alarm unit 136 to output the alarm sound from the speaker 158 and the alarm display of the LED 122. While stopping the fire alarm operation by the output, the second transmission circuit 148 of the second wireless communication unit 130 performs control to transmit the alarm stop interlocking signal to the other residential alarm devices 100.

  Note that if the alarm control unit 160 detects that the alarm control unit 160 has received the alarm stop interlocking signal from another home alarm device while the fire alarm sound indicating the link source is being output, the alarm control unit 160 The interlocking source can be identified without performing stop control on at least one of the alarm sound and the fire alarm display until at least a predetermined period elapses.

  When the alarm control unit 160 detects the operation of the alarm stop switch 120 or the effective reception of the alarm stop interlocking signal from another house alarm device during the output of the alarm sound indicating the interlock destination, the alarm control unit 160 controls the notification unit 136 to Control is performed to stop the operation of the alarm sound by the voice message from 158 and the fire alarm by the LED 122 alarm display.

  Further, the alarm control unit 160 performs control for returning an ACK signal accompanying the reception of the alarm stop interlocking signal in the same manner as when the fire interlocking signal is received. In addition, since it is the same also in each case mentioned later, description is abbreviate | omitted about the reply of the ACK signal accompanying communication between residence police.

  Further, the alarm control unit 160 is provided with a low battery failure monitoring function in which the power supply voltage supplied from the battery power supply 140 becomes less than a predetermined level in cooperation with a voltage monitoring circuit (not shown). Further, the alarm control unit 160 is provided with a sensor failure monitoring function for monitoring failures (including component deterioration and failure) of the sensor unit 134.

  The alarm control unit 160 also transmits an earthquake early warning according to the first radio communication protocol transmitted from the master station 12 of the municipal disaster prevention radio equipment 10 via the antenna 131 and the second reception circuit 148 of the second radio communication unit 130. An emergency earthquake warning report signal, tsunami warning report signal or emergency alert report signal including a common group code transmitted by protocol conversion of the report signal, tsunami warning report signal or emergency alert report signal by the relay adapter 200 is received and decoded. When effective reception is detected, a predetermined voice message indicating disaster prevention information corresponding to each reception is output from the speaker 158 of the notification unit 136 and, for example, the LED 122 is turned on.

  Here, as disaster prevention information corresponding to the earthquake early warning, for example, a voice message such as “Peep emergency earthquake early warning. Be wary of strong shaking” is repeatedly output from the spout 158 and the LED 122 is turned on, for example.
