Regarding the disaster prevention warning cooperation system to be made to.

Conventionally, alarm devices that detect and warn of abnormalities such as fires and gas leaks in houses have become widespread. Of these, residential fire alarms are called residential alarms.

For example, in such a Smoke detector, a sensor unit and an alarm unit are integrally provided in the Smoke detector, and when a fire is detected from a fire detection signal by the sensor unit, a predetermined pattern of fire alarm is output from the alarm unit. Since fire monitoring and alarms can be performed by the Smoke Detector alone without the need for dedicated receiving equipment, it is easy to install and inexpensive, and it has become widespread due to the mandatory installation in general housing. are doing.

We also propose an interlocking warning system that outputs a fire alarm in conjunction with other smoke alarms when a fire alarm is output by any of the smoke alarms by communicating between multiple smoke detectors. Has been put into practical use.

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

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

In such municipal disaster prevention radio equipment, when an Earthquake Early Warning is received or a tsunami warning is issued, the person in charge of disaster prevention administration modifies the voice signal when the corresponding alarm operation button on the console is operated. The emergency information signal is transmitted from the master station, the emergency information signal is received by the loudspeaker station installed outdoors or directly by the door-to-door receiver installed in the residence, and the voice signal is demodulated by demodulating the received signal. It plays and sends an alarm from the loudspeaker at the set volume to the area in charge, and outputs an alarm from the door-to-door receiver.

Moreover, in recent years, due to national policies, the conventional analog system has been abolished and the transition to a digital system has been promoted, and in the near future, the digital system will be introduced in all municipalities.

However, in such conventional municipal disaster prevention radio equipment, the emergency information signal transmitted from the master station is received by the loudspeaker station installed outdoors, and the loudspeaker sends an alarm to the jurisdiction area at a loud volume. However, when alarms are output from multiple loudspeaker stations at the same time, there is a problem that it is difficult to hear the alarm contents because multiple sounds interfere with each other in the place where the sounds from both reach, and the deadline is also. If you are indoors, there is still the problem that it is difficult to hear the outdoor alarm from the loudspeaker station.

In order to solve this problem, it is sufficient to install a dedicated receiver for each dwelling unit, but the installation cost is significantly increased, and maintenance is time-consuming and time-consuming, which is not realistic.

Also, if a door-to-door receiver is installed in a dwelling unit, you can only hear warnings such as Earthquake Early Warnings and tsunami warnings within the range where you can hear the sound from the door-to-door receiver. There are problems such as high cost and the need to secure installation space in various places.

In addition, the door-to-door receiver may not be able to receive radio waves with sufficient strength due to poor radio wave conditions depending on the room, and even if it is installed in such a place, it may not function effectively.

In order to solve this problem, the inventor of the present application converts the emergency information notification signal transmitted from the municipal disaster prevention radio equipment into a protocol by a relay adapter and transmits it to the residential police station installed in the house to output disaster prevention information. We are proposing a disaster prevention information cooperation system that is designed to be used.

In such a disaster prevention information cooperation system, it is necessary to output disaster prevention information from the Smoke Detector by regular tests and check the operation, which is realized by the test operation of the master unit installed in the municipal disaster prevention radio equipment. Although it is possible, there is a problem that it takes time and effort in artificial operation. It is also conceivable to install a test timer on the Smoke Detector side to perform an automatic test, but it is difficult for the test timer to have time information in terms of cost, such as the initial start time of the test timer and the accumulation of timer errors. Therefore, there remains a problem that the test notification of disaster prevention information may be performed during sleep at night.

In order to solve this problem, the emergency information notification signal transmitted from the regional disaster prevention radio equipment is converted into a protocol by a relay adapter and transmitted to an alarm such as a fire alarm that is obliged to be installed in a house to provide an Earthquake Early Warning. A disaster prevention alarm cooperation system that outputs disaster prevention information such as a tsunami warning has been proposed (Patent Document 1).

According to such a disaster prevention warning cooperation system, it is possible to construct a system for notifying an Earthquake Early Warning or a tsunami warning for each dwelling unit at low cost, and at the same time, for example, by using an emergency information receiving device installed in a regional disaster prevention radio facility. Since the test broadcast of the Earthquake Early Warning transmitted at noon on the first day of every month was detected and the test interlocking signal was transmitted to the alarm device after protocol conversion by the relay adapter for testing, the regional disaster prevention radio equipment and alarm device It is possible to periodically and automatically test the cooperative operation and the notification operation of the alarm device, and improve the reliability of the cooperative system operation.

However, if the test interlocking signal is transmitted to the Smoke Detector based on the test broadcast of the Earthquake Early Warning transmitted at noon on the first day of every month, the Smoke Detector that received the test interlocking signal will , Every time, the voice message of the test disaster prevention information such as "Peepy emergency warning test will be performed. An emergency warning has been issued." Will be repeatedly broadcast and output, and some users may feel the voice message of the test disaster prevention information noisy. There is a possibility that the usability will deteriorate.

In FIG. 1, the disaster prevention warning cooperation system according to the present invention is a house built in the same target area as the municipal 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. It is composed of an alarm system equipped with a wireless residential police device (household fire alarm device) 100 that detects a fire installed in 24 and gives an interlocking warning.

Here, the municipal disaster prevention radio equipment 10 wirelessly transmits, receives, and relays a signal according to a predetermined first wireless communication protocol, while the Smoke Detector 100 transmits an interlocking signal according to a different predetermined second wireless communication protocol. , Receive and relay to give an interlocking alarm. The first wireless communication protocol corresponds to the first communication protocol of the claim, and the second wireless communication protocol corresponds to the second communication protocol of the claim.

Further, the Smoke Detector 100 forms a unique group for each of the installed houses 24, and the interlocking signal transmitted from the Smoke Detector 100 includes a predetermined group code, and when the interlocking signal is received. When the group code obtained by decoding the interlocking signal matches the group code to which the interlocking signal belongs, the effective reception of the interlocking signal is detected and the interlocking alarm is issued.

The municipal disaster prevention radio equipment 10 is configured by appropriately arranging a master station 12, an operation console 14, a loudspeaker 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-level station provided in the city hall, village office, etc., and has two-way communication with the relay station 22 and the loudspeaker station 16, as well as downlink communication with the door-to-door receiver 14 in the vicinity of the master station 12. Do. The relay station 22 is installed on the mountaintop, for example, in consideration of an area where radio waves do not reach, and performs bidirectional relay between the master station 12 and the loudspeaker station 16 and relay from the master station 12 to the door-to-door receiver 20.

Note that FIG. 1 shows a case where the door-to-door receiver 20 is installed in a place other than the house 24, for example, in a public facility such as a public hall, and can be installed in the house 24 if necessary. In the form, since the disaster prevention information is notified and output by using the dwelling guard 100 provided in the house 24, the dwelling guard 100 covers a part of the functions of the door-to-door receiver 20. Therefore, the dwelling unit The receiver 20 does not necessarily have to be installed in the house 24. The house 24 also includes a dwelling unit and a house.

In addition, the municipal disaster prevention radio equipment 10 is wiredly connected to the console 14 and the retransmission slave station that relays radio waves to a limited area such as a valley where radio wave propagation is poor, and the master station is connected from a place other than the master station 12. A remote control station that controls 120 to selectively call a slave station and make a loudspeaker report is installed as needed. In addition, in FIG. 1, the case where one relay station 22 is arranged is taken as an example, but by installing a plurality of relay stations 22 and retransmitting slave stations as needed, the master station 12 and a plurality of relay stations 12 can be installed. A disaster prevention wireless network is constructed by connecting the door-to-door receiver 20 and the loudspeaker station 16 with a wireless line.

Further, in the present embodiment, the emergency information receiving device 15 is provided for the master station 12. The emergency information receiving device 15 automatically reproduces and outputs a broadcast signal when it detects the reception of an emergency warning broadcast or an earthquake early warning, which is an emergency information broadcast, and when it detects the reception of a test signal of an emergency warning broadcast, the emergency information receiving device 15 automatically reproduces and outputs the broadcast signal. , The master unit 12 transmits a test report signal. Further, when the emergency information receiving device 15 detects the reception of the Earthquake Early Warning, the master station 12 automatically transmits the Earthquake Early Warning notification signal.

The communication method of the municipal disaster prevention wireless communication equipment 10 is TDMA (Time Division Multiple Access) -TDD (Time Division Multiple Access) -TDD (Time Division Multiple Access) -TDD (Time Division Multiple Access) -TDD (Time Division Multiple Access) -TDD (Time Division Multiple Access) -TDD (Time Division Multiple Access) -TDD (Time Division Multiple Access) -TDD (Time Division Multiple Access) -TDD (Time Division Multiple Access) Time division duplex: Time Division Duplex) system. Specifically, it complies with the radio section interface standard of the digital broadcast communication system for disaster prevention administration by the TDMA-TDD system of the municipal digital disaster prevention wireless communication system in the 60 MHz band specified in Article 58-2-12 of the Radio Equipment Regulations. ..

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

Referring to FIG. 1 again, in the present embodiment, the relay adapter 100 is installed outdoors for each service area in which the service area of the municipal disaster prevention radio equipment is divided according to the situation of the area, and the relay adapter 100 is installed. Is installed, for example, on a support column in which a loudspeaker station 16 is installed. The relay adapter 200 receives a notification signal according to the first wireless communication protocol transmitted from the master station 12 or via the relay station 22, and transmits the notification signal to the second station 100 side. 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 Smoke Detector 100 installed in each house 24 receives and decodes the interlocking signal and detects the common group code, it self. Even if it does not match the group code to which the relay adapter 200 belongs, the interlocking signal from the relay adapter 200 is effectively received and the notification output is performed. Here, the interlocking signal for which the common group code is set means the interlocking signal without group designation in the claims.

The communicable area that serves as the service area of the relay adapter 200 is, for example, an area that includes the Smoke Detector 100 installed indoors of a house that exists in the area where the sound from the loudspeaker 18 of the loudspeaker station 16 reaches. Therefore, 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 needed. Further, by installing the relay adapter 200 in the vicinity of the loudspeaker station 16, for example, on a support column, the AC power supply of the loudspeaker station 16 can be used as it is as the AC power supply for the relay adapter 200 installed outdoors. Since it is not necessary to secure a dedicated outdoor AC power supply for the 200, the equipment configuration can be simplified and the installation cost can be reduced.

The master station 12 may automatically transmit the output signal based on the signal reception detection.

Here, emergency information broadcasts received by a television receiver, an FM receiver, or an AM receiver include an Earthquake Early Warning (EEW) and an emergency warning broadcast (EWS: Emergency Warning System). The Earthquake Early Warning is a warning issued by the Japan Meteorological Agency with an estimated maximum seismic intensity of 5 lower or higher for the general public, and warns areas where strong shaking is expected that a serious disaster may occur due to seismic motion. It is a broadcast. The Earthquake Early Warning is, for example, "(Twice chime sound) Earthquake Early Warning. Please be wary of strong shaking ...." and repeat the broadcast.

The emergency warning broadcast is a warning that is given when a large-scale disaster such as an earthquake occurs or when a tsunami warning is announced, and automatically switches on the TV or radio receiver in the standby state. Type 1 start signal, type 2 start signal and end signal are used for the start and end of the emergency warning broadcast. The first-class start signal is sent when a warning declaration for the Tokai earthquake is announced, or when an evacuation order is issued by the governor or chief of the local government, and the receiver is automatically turned on. Also, the Type 2 start signal is transmitted 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 type 1 or type 2 start signal, and automatically turns off the receiver. Further, in order to confirm the operation of the receiver, a test signal is transmitted once a month, for example, at a predetermined time, for example, at noon on the first day of every month. This test signal is the same as the end signal, and only the end signal is received. If so, make sure that the receiver operates normally.

In the following explanation, when the Earthquake Early Warning, the tsunami warning, and the emergency warning are collectively represented, they are referred to as emergency information, and the signals transmitted from the master station 12 indicating these are referred to as the Earthquake Early Warning notification signal and the tsunami warning notification. They are called signals and emergency warning notification signals, and when they are collectively expressed, they are called emergency information notification signals. Further, a signal transmitted from the master station 12 based on the reception detection of the test signal of the emergency warning broadcast by the emergency information receiving device 15 is called a test notification signal.

Further, a signal transmitted and received between the Smoke Detector 100s in the alarm system is called an "interlocking signal", and the interlocking signal includes a fire interlocking signal, a fire recovery interlocking signal, an alarm stop interlocking signal, a failure interlocking signal, and the like. When the relay adapter 200 receives an Earthquake Early Warning notification signal, a tsunami warning notification signal, an emergency warning notification signal, and a test notification signal from the master station 12 according to the first wireless communication protocol, the relay adapter 200 receives the second wireless communication based on the notification signal. It will be converted to an interlocking signal including a common group code according to the protocol (interlocking signal without group designation) and relayed, and the interlocking signal in this case will be an earthquake early warning interlocking signal, a tsunami warning interlocking signal, and an emergency warning interlocking. It is called a signal and a test interlocking signal. Further, when the Smoke Detector 100 receives an Earthquake Early Warning interlocking signal, a tsunami warning interlocking signal, an emergency alarm interlocking signal and a test interlocking signal from the relay adapter 200 or another Smoke detector, the interlocking device 100 belongs to itself based on the interlocking signal. Generates an interlocking signal including the group code assigned to the group and relays it to other Smoke detectors.

(Configuration of emergency information receiving device 15)
FIG. 5 is a block diagram showing a schematic configuration of an emergency information receiving device provided for the master station of FIG. This is an example, and each function can be separated and integrated arbitrarily. Further, any part or all of each of the functions may be executed by software (program) or hardware.

In FIG. 5, the emergency information receiving device 15 includes a processor 82, an FM receiving unit 84 to which an FM antenna 83 is connected, a sound amplifier unit 85, a speaker 86, a display unit 88, an operation unit 90, a memory 192, and an interface unit 94. The processor 82 is provided with a reception control unit 96 as a function realized by executing a program.

The FM receiving unit 84 synchronizes the tuner with the FM station selected by the operation of the operating unit 90, receives the broadcast radio wave by the FM antenna 83, demodulates the broadcast signal, and outputs it as an audio signal. The sound amplifier unit 85 is stopped in the standby state, and therefore, the reproduction output of the FM broadcast received from the speaker 86 is not performed.

When the analysis process of the reception control unit 96 provided in the processor 82 detects the effective reception of the Earthquake Early Warning signal, the tsunami warning signal, or the emergency warning signal, the sound amplifier unit 55 is switched to the operating state, and at that time, the sound amplifier unit 55 plays back. The broadcast contents of the output emergency earthquake early warning signal, tsunami warning signal, or emergency warning signal are reproduced and output from the speaker 86. The display unit 88 performs various displays necessary for receiving FM broadcasts, such as a standby reception display, an earthquake early warning reception display, a tsunami warning reception display, an emergency warning reception display, and a channel selection frequency display.

The receiver control unit 96 provided in the processor 82 inputs and analyzes the FM broadcast signal received and demodulated by the FM receiver 84, and analyzes the FM broadcast signal, and is an emergency earthquake flash signal, a tsunami warning signal, an emergency warning signal, or a test signal in an emergency warning broadcast. The presence or absence of effective reception of is detected.

The analysis and detection of the Earthquake Early Warning signal by the reception control unit 96 detects that the Earthquake Early Warning signal has been effectively received by the analysis processing of the two chime sounds that flow first in the Earthquake Early Warning broadcast signal, and based on this. The sound amplifier unit 85 is operated for a predetermined time, for example, to control the earthquake early warning to be reproduced and output from the speaker 86. The chime sound analysis of the Earthquake Early Warning by the reception control unit 96 is performed by, for example, the vector correlation method described in Patent Document 3.

Further, the analysis and detection of the tsunami warning signal by the reception control unit 96 analyzes and detects the reception of the type 2 start signal flowing in the first 10 seconds of the tsunami warning signal, and based on this, for example, the sound amplifier unit 85 is predetermined. It is controlled to operate for a time to reproduce the tsunami warning broadcast and output it from the speaker 86. Further, when the reception of the end signal transmitted after a predetermined time, for example, 10 minutes after the analysis detection of the second type start signal is analyzed and detected, the operation of the sound amplifier unit 85 is stopped based on this and the speaker 86 is used. Control may be performed to stop the output of the broadcast sound.

Further, in the analysis and detection of the emergency warning signal by the reception control unit 96, when the validity of the type 1 start signal flowing in the first 10 seconds of the emergency warning signal is analyzed and detected, the sound amplifier unit 85 is determined based on this. It is controlled to operate for a time to reproduce the emergency warning broadcast and output it from the speaker 86. Further, when the reception of the end signal transmitted after a predetermined time, for example, 10 minutes after the analysis detection of the first type start signal is analyzed and detected, the operation of the sound amplifier unit 85 is stopped based on this and the speaker 86 is used. Control may be performed to stop the output of the broadcast sound.

Further, the analysis and detection of the test signal of the emergency warning broadcast by the reception control unit 96 is performed as a first-class start signal as a test signal at noon on the first day of every month in the case of NHK (R) as a test signal of the emergency warning broadcast. Or, since only the end signal is transmitted without transmitting the type 2 start signal, when the validity of only the end signal flowing in 10 seconds is analyzed and detected, the reception of the test signal is determined and used for this. Based on this, the sound amplifier unit 85 is operated for a predetermined time to play an emergency alarm test broadcast and control the output from the speaker 86. Further, the interface unit 96 outputs a test signal to the master station 12, and the master station 12 first outputs the test signal. A test notification signal according to the communication protocol is generated and transmitted by broadcast communication targeting all the residential police 100. Further, when the reception control unit 96 analyzes and detects the reception of the end signal transmitted again after a predetermined time from the analysis detection of the end signal, the operation of the sound amplifier unit 85 is stopped based on this and broadcast from the speaker 86. Controls to stop the sound output.

Here, as the first-class start signal, second-class start signal, and end signal in analog broadcasting, audio signals are used, and bit 1 of the digital signal is frequency-modulated to 1024 Hz audio signal and bit 0 is frequency-modulated to 640 Hz audio signal. The FSK signal is transmitted at a communication speed of 64 bps, and can be heard as a fluttering sound.

On the other hand, in digital broadcasting, since it is transmitted with predetermined data defined as an emergency warning broadcasting identifier, this is received and analyzed for detection.

Further, the reception control unit 96 operates the sound amplifier unit 85 to reproduce the broadcast sound at that time and starts the output from the speaker 86, and then, when a predetermined time elapses for the emergency earthquake bulletin, a tsunami warning or an emergency warning is given. For example, when the effective reception of the end signal is analyzed and detected, and for the test broadcast, for example, when the effective reception of the end signal is analyzed and detected again, the operation of the sound amplifier 55 is stopped and the output of the broadcast sound is stopped from the speaker 86. Control to make it.

Here, the equipment power sources of the master station 12, the console 14, the emergency information receiving device 15, etc. are commercial AC power sources, but a battery power source is provided for backup in the event of a power failure.

Although the emergency information receiving device 15 of FIG. 5 receives the FM broadcast, the emergency information signal and the test signal may be detected by receiving and analyzing the television broadcast (digital TV broadcast). In this case, instead of the FM receiving unit 84 to which the FM antenna 83 is connected, a digital TV receiving unit to which a TV antenna is connected is provided, and the TV broadcast audio data signal received and demolished by the digital TV receiving unit by the reception control unit 96. And, the TV broadcast data signal may be input and analyzed to detect the effective reception of the emergency earthquake flash signal, the tsunami warning signal, the emergency warning signal, or the end signal of the emergency warning broadcast. The digital TV receiver may be a receiver of a 1-segment partial reception service for mobile phones and mobile terminals known as 1Seg.

Further, as the emergency information receiving device 15 of FIG. 5, the emergency information signal and the test signal may be detected by receiving and analyzing the AM broadcast. In this case, instead of the FM receiving unit 84 to which the FM antenna 83 is connected, an AM receiving unit to which the AM antenna is connected is provided, and the receiving control unit 96 inputs the AM broadcast audio signal received and demodulated by the AM receiving unit. The analysis may be performed to detect the effective reception of an emergency earthquake flash signal, a tsunami warning signal, an emergency warning signal, or a test signal for an emergency warning broadcast.

(Structure of loudspeaker station 16)

(Overview of Smoke Detector 100)
With reference to FIG. 1 again, the housing police 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, and a fire breaks out in each corresponding monitoring area of each part of the house. The presence or absence is monitored.

Now, if a fire breaks out in a certain house 24, for example, the housing police 100 detects the fire and starts an alarm. Detecting this fire and starting an alarm is called "alarming" in the Smoke Detector.

When the Smoke Detector 100 issues a report, the Smoke Detector 100 functions as an interlocking source and wirelessly transmits a fire interlocking signal to another Smoke Detector to be the interlocking destination according to a predetermined second wireless communication protocol. When the fire interlocking signal from the interlocking source Smoke detector 100 is effectively received, the other Smoke detector performs an alarm operation as an interlocking destination 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 Smoke Detector 100 effectively receives the interlocking signal. I am trying to detect it. Further, the Smoke Detector 100 that has effectively received the interlocking signal relays and transmits the interlocking signal as needed. The group code is set as a code unique to each alarm system, and each Smoke Detector can identify and process only the interlocking signal related to the alarm system to which it belongs by this code.

As the alarm operation of the Smoke Detector 100, which is the interlocking source, a fire alarm sound is output by a voice message such as "Woo Woo fire alarm has been activated. Please confirm." On the other hand, the interlocking destination Smoke Detector 100 outputs a fire alarm sound with a voice message such as "Woo, another fire alarm has been activated. Please check."

Further, as an alarm display accompanying the fire alarm of the residential alarm 100 that is the interlocking source, for example, an LED is turned on. On the other hand, in the interlocking destination Smoke Detector 100, the LED blinks. This makes it possible to distinguish between the alarm display by the LED in the interlocking source alarm and the interlocking destination alarm.

The interlocking source LED may be blinking and the interlocking destination LED may be lit, or the interlocking source alarm and the interlocking destination alarm may be blinking, blinking, or lit display of the same LED. Further, for example, a two-color display may be provided in which a red LED and a yellow LED are provided, the interlocking source drives the red LED, and the interlocking destination drives the yellow LED. Of course, a two-color LED that can emit both red and yellow can be adopted by integrating the two LEDs.

If the alarm stop switch is operated while the Smoke Detector 100 is emitting an alarm sound, the alarm sound and the alarm display are stopped. At this time, for example, when the alarm stop operation is performed by the interlocking source Smoke Detector 100, the alarms of all the Smoke Detector 100 are stopped, and the alarm stop operation is performed by the interlocking destination Smoke Detector 100. In the case of a fire, the alarm of the interlocking source Smoke Detector 100 is not stopped, but the alarm of the interlocking destination Smoke Detector 100-2 is stopped so that the location of the fire can be known.

In the case of Japan, transmission and reception by the predetermined second radio communication protocol in the Sumitomo Mitsui 100 is performed by, for example, STD-30 (low power security system radio station) known as a standard of a specific low power radio station in the 400 MHz band. Radio equipment standard) or STD-T67 (standard of radio equipment for specified low power radio station telemeter, telecontrol and data transmission). Of course, if it is used outside of Japan, it will have contents that comply with the standards of the assigned radio stations in that area. The transmission power of the Smoke Detector 10 conforming to the specified low power radio station is 10 mW or less in the case of STD-30, 10 mW or less or 1 mW or less in the case of STD-T67, and the line-of-sight communication distance is about 100 meters. It becomes.

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

Further, when a test interlocking signal including a common group code according to the second wireless communication protocol transmitted by protocol conversion by the relay adapter 200 is received and decoded to detect effective reception, predetermined test disaster prevention information is obtained. Is output as a notification.

When the Smoke Detector 100 detects the effective reception of the Earthquake Early Warning interlocking signal from the relay adapter 200, for example, "Peepy Earthquake Early Warning. Please be wary of strong shaking." As disaster prevention information corresponding to the Earthquake Early Warning. The voice message such as is repeatedly notified and output, and the LED is turned on, for example.

In addition, when the Smoke Detector 100-1 detects the effective reception of the tsunami warning interlocking signal from the relay adapter 200, for example, "Peepy tsunami warning has been issued. Approaching the coast" as disaster prevention information corresponding to the tsunami warning. Instead, evacuate to a hill. ”Is repeatedly notified and output a voice message and turn on the LED, for example.

In addition, when the housing police 100-1 detects the effective reception of the emergency alarm interlocking signal from the relay adapter 200, a voice message such as "Peepy emergency alarm has been issued" is used as disaster prevention information corresponding to the emergency alarm. Is repeatedly notified and output, and the LED is turned on, for example.

Further, when the Smoke Detector 100-1 detects the effective reception of the test interlocking signal from the relay adapter 200, the LED 122 is turned on, blinks or blinks for a predetermined time to notify and output the test disaster prevention information. Further, when the alarm device 100-1 detects the effective reception of the test interlocking signal from the relay adapter 200 and detects the on operation of the alarm stop switch 120 while the LED 122 is operating, for example, "Peep emergency alarm test is performed. A voice message such as "An emergency alarm has been issued." Is repeatedly notified and output. The test disaster prevention information is performed by setting a volume lower than the actual alarm volume to reduce power consumption.

Further, each time the Smoke Detector 100-1 receives the test interlocking signal, it continuously counts the number of times N for which there is no notification output by the voice message of the test disaster prevention information, and the continuous number N becomes a predetermined threshold number Nth. When it reaches, the test disaster prevention information is notified and output by voice message.

Each disaster prevention information or test disaster prevention information notified and output from the Smoke Detector 100 is stopped, for example, after a predetermined time has elapsed or after a predetermined number of notifications.

Further, the housing police device 100 transmits an emergency earthquake flash report interlocking signal, a tsunami warning interlocking signal, an emergency alarm interlocking signal, or a test 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 it is received, and when effective reception is detected by decoding this, an emergency earthquake flash report interlocking signal, a tsunami warning interlocking signal, or an emergency alarm interlocking according to the second radio communication protocol including the group code of the interlocking group to which the self belongs based on each is detected. A signal or a test interlocking signal is generated and transmitted to another housing police 100 belonging to the same group to notify the corresponding disaster prevention information or the test disaster prevention information in the same manner as when each interlocking signal is received from the relay adapter 200. Output.

Here, when the communication routes according to each wireless communication protocol in FIG. 1 are arranged, the routes between the master station 12 and the relay station 22 in the town / village disaster prevention radio equipment 10, the door-to-door receiver 20 of the loudspeaker station 16, and the residential police device 100, respectively. , And the route between the door-to-door receiver 20 and the relay adapter 200 of the relay station 22 and the loudspeaker station 16 is the first wireless communication protocol path 11a, and is between the relay adapter 200 and the residential police 100 of each house 24.

A protrusion is provided in the center of the cover 112, a plurality of smoke inlets are opened around the protrusion, and a smoke detection unit 116 is arranged inside the protrusion, and smoke from a fire flows into the smoke detection unit 116. When the predetermined concentration is reached, the alarm control unit, which will be described later, detects a fire. As the smoke detection unit 116, for example, a known scattered light type smoke detection 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 built in behind the acoustic hole 118 so that an alarm sound and a voice message can be output. An alarm stop switch 120 is provided on the lower side of the cover 112.

When the switch cover formed of the translucent member is pressed by the alarm stop switch 120, the built-in push switch (not shown) is pressed. An LED 122 that displays an alarm or the like is arranged in the vicinity of the push switch inside the switch cover.

The alarm stop switch 120 also functions as an inspection switch for instructing the self-inspection of the function of the Smoke Detector 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 the normal state, a self-inspection is performed for a predetermined function, and the result is obtained by the LED 122, the speaker, or the like. Is notified. Here, the normal state means at least a state in which 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 thereof is provided on the upper part of the back side of the main body 114, and a screw or the like is screwed into the wall surface or the like of the room to be installed, and the screw is passed through the insertion hole of the mounting hook 115 to be hooked. Therefore, the Smoke Detector 100 can be fixedly installed on the wall surface in a so-called wall-mounted manner.

(Configuration of relay adapter 200)
FIG. 9 is a block diagram showing an embodiment of a relay adapter and a resident police device provided in the disaster prevention alarm cooperation system of FIG. This is an example, and each function can be separated and integrated arbitrarily. Further, any part or all of each of the functions may be executed by software (program) or hardware.

In FIG. 9, the relay adapter 200 will be described first. The relay adapter 200 includes a processor 202, and the first reception is connected to the processor 202 by connecting an antenna 206 that receives a notification signal according to the first wireless communication protocol transmitted from the master station 12 of the municipal disaster prevention radio equipment 10. The first wireless communication unit 204 including the circuit 216, the second wireless communication unit 208 including the second transmission circuit 218 connected to the antenna 210 that transmits a notification signal according to the second wireless communication protocol to the residential police device 100, A power supply circuit unit 212 that generates a DC power supply from AC100V and supplies it to each unit, and a standby power supply unit 214 that uses a secondary battery such as a battery are provided.

The first receiving circuit 216 of the first wireless communication unit 204 complies with the municipal digital disaster prevention wireless communication system standard transmitted from the master station 12 or the relay station 22 of the municipal disaster prevention radio equipment 10 via the antenna 206, for example, in the 60 MHz band. According to the first wireless communication protocol, the earthquake early warning signal, the tsunami warning signal, the emergency warning signal, or the test notification signal is received and demolished 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 an emergency earthquake flash report signal, a tsunami warning signal, an emergency warning signal, or a test report signal received and demodulated via the antenna 206 of the first wireless communication unit 204 and the first receiving circuit 216. Then, when the effective reception is detected, an emergency according to the second radio communication protocol conforming to the standard of a specific low power radio station of, for example, 400 MHz band, which has the same format configuration as the interlocking signal shown in FIG. An earthquake flash report interlocking signal, a tsunami warning interlocking signal, an emergency alarm interlocking signal, or a test interlocking signal is generated and output to the second wireless communication unit 208.

Here, the group code included in the interlocking signal 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 the Smoke Detectors, and there is no so-called group designation. It differs from the interlocking signal that is transmitted and received between the Smoke Detectors that have a unique group code set in that it is an interlocking signal.

The second transmission circuit 218 of the second wireless communication unit 208 transmits the earthquake early warning interlocking signal, the tsunami warning interlocking signal, the emergency alarm interlocking signal or the test interlocking signal input from the processor 202 via the antenna 210 according to the second wireless communication protocol. Send to the housing police 100. The power transmitted from the antenna 210 by the second transmission circuit 216 is, for example, 1 W or less so that the radio waves can sufficiently reach the residential police 100 installed in the entire service area under the jurisdiction of the relay adapter 200 installed outdoors. Set a relatively large transmission power. Since such transmission power of 1 W or less deviates from the standard of a specific low power radio station in the 400 MHz band, which is a transmission power of 10 mW or less or 1 mW or less, a license application for a radio station necessary for its installation is required. Such measures are required.

(Structure of Smoke Detector 100)
Next, the Smoke Detector 100 of FIG. 8 will be described. The Smoke Detector 100 includes a processor 124 known as a one-chip CPU, and a second wireless communication unit 130, a memory 132, and a memory 132 that transmit and receive an interlocking signal according to a predetermined second wireless communication protocol to the processor 124. 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 each necessary unit.

The second wireless communication unit 130 includes a second transmission circuit 146 and a second reception circuit 148 to which the antenna 131 is connected. The second radio communication unit 130 fires and fires with another Smoke Detector 100-2 via the antenna 131 according to the second radio communication protocol conforming to the standard of a specific low power radio station in the 400 MHz band, for example. In addition to transmitting and receiving various interlocking signals such as recovery, alarm stop, and failure, it also receives an earthquake early warning interlocking signal, a tsunami warning interlocking signal, an emergency alarm interlocking signal, or a test interlocking signal transmitted from a relay adapter 200 installed outdoors.

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 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. = Repeated, for example, 4 times with a pause of 2 seconds. This T1 = 3 second transmission and T = 2 second pause conform to the standard of the specified low power radio station. Further, in the transmission operation of T1 = 3 seconds, for example, 2.8 seconds is the transmission of the dummy signal from the beginning, 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.

Further, the reception by the second radio communication protocol in the second reception circuit 148 of the second radio communication unit 130 intermittently receives the interlocking signal from another smoke detector belonging to the same group as the smoke detector 100 and the relay adapter 200. .. Intermittent reception repeats the reception operation for a receivable time T4, for example T4 = 100 milliseconds, every predetermined cycle T3, for example, every T3 = 7 seconds, and carrier senses a transmission dummy signal during the receivable time T4. When it is detected by, it switches to continuous reception for a predetermined time and receives an interlocking signal following the dummy signal.

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 referred to as reception including this decoding. Further, in particular, when it is distinguished that it is determined to be a valid signal as a result of decoding, it is called effective reception. Further, "detection of reception" in the claims means "effective reception" or "detection of effective reception".

Further, in the second wireless communication protocol of the second wireless communication unit 130, when the Smoke Detector 100 itself detects a fire or an event other than a fire and transmits an interlocking signal, or emergency information from the relay adapter 200 without specifying a group. When an interlocking signal or test interlocking signal is received, an emergency information interlocking signal or test interlocking signal specified by a group based on this is generated and transmitted to another Smoke detector, it belongs to the same group as the Smoke detector 100, and this It is monitored whether or not a confirmation response signal (hereinafter referred to as "ACK signal") indicating that the interlocking signal has been normally received is effectively received from another Smoke detector that has received the signal.

When it detects that the ACK signal is not received among the other smoke detectors, the smoke detector 100 transmits a relay request interlocking signal to the other smoke detectors for which the ACK signal is received, and the relay request is made. The interlocking signal with a relay request is relayed from the Smoke detector that has received the interlocking signal to the Smoke detector that has not responded to the AKC signal. The AKC signal unresponsive Smoke detector that relayed and received the interlocking signal with a relay request returns an ACK signal to the interlocking signal with a relay request, and this ACK signal relays the other Smoke detector (relay of the reply). After that, it is received by the interlocking source Smoke Detector 100. If there is a Smoke Detector that does not receive the ACK signal even with this, it is determined that there is a communication failure or the like, and predetermined notification processing, interlocking processing, interlocking processing described later, etc. are performed.

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

As shown in FIG. 10, the interlocking signal 150 transmitted and received by the second wireless communication protocol of the second wireless communication unit 130 is configured as a format including a serial number 152, a source identification code 154, a group code 155, and an event code 156. ing. The serial number 152 is a code that is independently generated for each Smoke detector, and is a serial number that indicates the generation order or transmission order of the interlocking signal 150. Based on this, for example, management such as prohibition of re-relaying can be performed. The source identification code 154 is, for example, the serial number of the smoke detector that identifies each smoke detector, and the group code 155 is linked to each other within the group of the smoke detector 100 installed in the house 24 as shown in FIG. It is a code for forming an interlocking group to be performed.

Further, in the present embodiment, the interlocking signal according to the second wireless communication protocol transmitted from the relay adapter 200 can be effectively received by all the Smoke Detector 100 installed in the house 24 in the target area. Since it is necessary, a common group code common to all groups is set as the group code 155. Since this common group code is effectively received by all the Smoke Detector 100s constituting different interlocking groups, it is a code meaning that no group is specified.

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

Although the above-mentioned code indicating "relay request" is omitted here, it can be naturally added to the event code by increasing the number of bits.

Further, in the present embodiment, the earthquake early warning signal, the tsunami warning signal, and the emergency earthquake warning signal and the tsunami warning signal transmitted from the master station 12 of the municipal disaster prevention radio equipment 10 received by the second wireless communication unit 130 via the protocol conversion of the relay adapter 200. As an interlocking signal based on the emergency warning notification signal, that is, as an event code corresponding to the earthquake early warning interlocking signal, the tsunami warning interlocking signal, the emergency warning interlocking signal, and the test interlocking signal.
0111 = Earthquake Early Warning 1000 = Tsunami Warning 1001 = Emergency Warning 1010 = Test is added.

In addition, both the identification code indicating the source (interlocking source) Smoke detector and the identification code of the relay Smoke detector are added to the interlocking signal relayed and transmitted by the Smoke detector. Further, an identification code for designating the transmission destination may be added.

Further, although the above-mentioned code indicating "relay request" is omitted here, it can be naturally added to the event code by assigning it to, for example, "1111". In addition, 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 by, for example, a scattered light type smoke detection principle and outputs a smoke detection signal according to the smoke concentration.

The notification unit 136 is provided with a speaker 158, which is an acoustic output device that outputs an alarm sound, and an LED 122 that displays an alarm, together with drive circuits (not shown). The speaker 158 receives control from the alarm control unit 160 and outputs a voice message, an alarm sound, or the like based on various data or the like stored in the memory 132 or the like by the Smoke Detector 100. The LED 122 displays an abnormal condition such as a fire or other event by blinking, blinking, lighting, or the like.

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 fire or failure alarm sound is output from the notification unit 136 by the speaker 158 or when an alarm is displayed by the LED 122. For example, if the alarm stop switch 120 is operated during the alarm indicating the interlocking source, the alarm sound and the alarm display are stopped, while if the alarm stop switch 120 is operated during the alarm indicating the interlocking destination, the alarm sound is stopped. An alarm stop process is performed such that the alarm display is stopped or stopped after a predetermined time.

On the other hand, in the normal monitoring state in which the alarm indicating the interlocking source or interlocking destination is not performed, the alarm stop switch 120 functions as an inspection switch, and when the alarm stop switch 20 is operated in this state, a predetermined self-inspection operation is performed. Is executed, and a voice message or the like indicating the inspection result is output from the notification unit 136.

The memory 132 stores the serial number 152, the identification code 154, the 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 dry battery having a predetermined number of cells, and supplies power to each necessary part. As for the battery capacity, the life of the Smoke Detector 100 is guaranteed to be 10 years, for example, by reducing the power consumption of the entire circuit unit.

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

Further, when the alarm control unit 160 detects the presence of a fire based on the smoke detection signal of the smoke detection unit 116 provided in the sensor unit 134, the alarm control unit 160 emits a fire alarm sound, for example, as an alarm operation indicating the interlocking source from the speaker 158 of the notification unit 136. In addition to controlling the repeated output of the voice message "Woo Woo Fire, please check", the LED 122 is turned on to display a fire alarm indicating the interlocking source, and the second wireless communication unit 130 The second transmission circuit 146 of the above is controlled to transmit a fire interlocking signal according to a predetermined second radio communication protocol from the antenna 131 to another Smoke Detector 100-2.

Further, when the alarm control unit 160 detects the effective reception of the fire interlocking signal transmitted or relayed from another residential alarm 100-2 via the second receiving circuit 148 of the antenna 131 and the second wireless communication unit 130. In addition, as an alarm indicating the interlocking destination, control is performed to repeatedly output an alarm sound, for example, a voice message such as "Woo, another fire alarm has been activated. Please check" from the speaker 158 of the notification unit 136, and the LED 122 blinks, for example. It is controlled to display an alarm indicating the interlocking destination. Further, the second transmission circuit 146 is controlled to transmit an ACK signal as a response signal (reply) accompanying the reception of the fire interlocking signal from the interlocking source.

When the alarm control unit 160 detects a fire recovery during the output of the fire alarm sound indicating the interlocking source, the alarm control unit 160 controls the notification unit 136 to perform a fire alarm operation by the alarm sound output from the speaker 158 and the alarm display output of the LED 122. At the same time as stopping the fire, the second transmission circuit 146 of the second wireless communication unit 130 controls the fire recovery interlocking signal to be transmitted to the other residential alarm 100-2 via the antenna 131.

When the alarm control unit 160 detects the operation of its own alarm stop switch 120 during the output of the fire alarm sound indicating the interlocking 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. The fire alarm operation by the output is stopped, and the second transmission circuit 146 of the second wireless communication unit 130 controls to transmit the alarm stop interlocking signal to the other residential alarm 100-2 via the antenna 131.

When the alarm control unit 160 detects that the alarm control unit 160 effectively receives an alarm stop interlocking signal from another smoke alarm system while the fire alarm sound indicating the interlocking source is being output, the alarm control unit 160 fires. At least one of the alarm sound and the fire alarm display can be identified by the interlocking source without stopping control until at least a predetermined period has elapsed.

Further, 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 residential alarm during the output of the alarm sound indicating the interlocking destination, the alarm control unit 160 controls the notification unit 136 to control the speaker. Control is performed to stop the operation of the alarm sound by the voice message from 158 and the fire alarm by the alarm display of the LED 122.

Further, the alarm control unit 160 controls to return the ACK signal accompanying the reception of the alarm stop interlocking signal, as in the case of receiving the fire interlocking signal. Since the same applies to each case described later, the description of the reply of the ACK signal accompanying the communication between the Smoke Detectors will be omitted.

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 a failure (including component deterioration, failure, etc.) of the sensor unit 134.

Further, the alarm control unit 160 receives 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 Earthquake Early Warning interlocking signal, a tsunami warning interlocking signal, or an emergency alarm interlocking signal including a common group code transmitted by converting a notification signal, a tsunami warning notification signal, or an emergency alarm notification signal into a protocol with a relay adapter 200 is received and decoded. When effective reception is detected, a predetermined voice message indicating disaster prevention information corresponding to each is output from the speaker 158 of the notification unit 136, and control is performed such that the LED 122 is turned on, for example.

Here, as disaster prevention information corresponding to the Earthquake Early Warning, for example, a voice message such as "Peepy Earthquake Early Warning. Please be wary of strong shaking." Is repeatedly output from the spice 158 and the LED 122 is turned on, for example.

In addition, as disaster prevention information corresponding to the tsunami warning, for example, a voice message such as "Peepy tsunami warning has been issued. Please evacuate to a hill without approaching the coast." Turn it on.

Further, as disaster prevention information corresponding to the emergency warning, for example, a voice message such as "Peepy emergency warning has been issued" is repeatedly notified and output from the spice 158, and the LED is turned on, for example.

Further, the alarm control unit 160 reports a test according to the first wireless communication protocol transmitted from the master station 12 of the municipal disaster prevention radio equipment 10 via the antenna 131 and the second receiving circuit 148 of the second wireless communication unit 130. When a test interlocking signal including a common group code transmitted by protocol conversion of the signal by the relay adapter 200 is received and the valid reception is detected by decoding the signal, the LED 122 is turned on, blinking or blinking for a predetermined time. Then, the test disaster prevention information is notified and output.

Further, when the alarm control unit 160 detects the effective reception of the test interlocking signal from the relay adapter 200 and detects the on operation of the alarm stop switch 120 while the LED 122 is operating, for example, "Peep emergency alarm test is performed. Emergency" A voice message such as "An alarm has been issued." Is repeatedly notified and output. The test disaster prevention information is performed by setting a volume lower than the actual alarm volume to reduce power consumption.

Further, each time the alarm control unit 160 receives the test interlocking signal, the alarm control unit 160 continuously counts the number of times N for which there is no notification output by the voice message of the test disaster prevention information, and the continuous number of times N reaches a predetermined threshold number Nth. In this case, the test disaster prevention information is notified and output by a voice message.

Each disaster prevention information or test disaster prevention information notified and output from the Smoke Detector 100 is stopped, for example, after a predetermined time has elapsed or after a predetermined number of notifications.

Further, the alarm control unit 160 includes an earthquake early warning interlocking signal, a tsunami warning interlocking signal, an emergency alarm interlocking signal, or a test interlocking signal including a common group code according to the second wireless communication protocol transmitted after the protocol conversion by the relay adapter 200. When a signal is received and it is decoded to detect effective reception, based on this, an Earthquake Early Warning interlocking signal, a tsunami warning interlocking signal, an emergency alarm interlocking signal, or a test interlocking signal including the group code of the interlocking group to which it belongs is output. It is generated and controlled to be transmitted to another residential police device via the second transmission circuit 146 and the antenna 131 of the second radio communication unit 130.

[Disaster prevention alarm cooperation system that superimposes control data on voice signals and transmits]
(Structure on the master station 12 side)
FIG. 15 is a block diagram showing a schematic configuration on the master station side used in another embodiment of the disaster prevention alarm cooperation system according to the present invention. By superimposing the emergency information control data signal for outputting the alarm on the voice signal and transmitting it, the residential police can cooperate with each other with almost no need for improvement or repair of the equipment used in the municipal disaster prevention radio equipment. It is characterized by doing so.

In FIG. 15, the master station 12 uses a processor (computer) as hardware, and provides a control unit 26, a voice input unit 28, and a telephone control unit 30 as functions realized by executing the program, and further, as hardware. A wireless communication unit 32 connected to an antenna 34 that performs wireless transmission / reception according to the first wireless communication protocol is provided, and this point is the same as that of the embodiment of FIG.

An operation console 14 is provided for the master station 12, and the operation console 14 is provided with an operation unit 36, a display unit 38, a master telephone 42, and the like. Further, an Earthquake Early Warning receiver 44 is provided to automatically receive the Earthquake Early Warning broadcast and output the Earthquake Early Warning detection signal to the master station 12, which is also the same as the embodiment of FIG. ..

In addition to this, in the present embodiment, the communication data generator 87 is connected to the microphone jack terminal 94 of the console 14 to which the plug of the broadcasting microphone 40 is connected, and the master station 12 is connected via the microphone connection circuit unit 96. It is connected to the voice input unit 28 of. Further, the communication data generator 87 includes a microphone jack terminal 95, to which a broadcasting microphone 40 is connected. Although the microphone connection circuit 94 includes an audio amplifier, the microphone jack terminal 94 may be directly connected to the audio input unit 28 without providing the microphone connection circuit 96.

The communication data generator 82 connects a plurality of operation switches 89a to 89n to the data modulator 86. Emergency information control data signals having a predetermined bit length are assigned to the operation switches 89a to 89n. For example, the operation switch 84a: emergency earthquake warning control data signal operation switch 84b: tsunami warning control data signal operation switch 84c: emergency warning control data. Signals etc. are assigned. In addition to this, an appropriate control data signal such as a test control data signal can be assigned as needed.

When the data modulator 91 inputs an on signal operated by the operation switches 89a to 89n, it generates an emergency information control data signal consisting of a binary code having a predetermined bit length, and 1/0 of the digital data is a carrier signal in the voice frequency band. By allocating, for example, 2400 Hz / 3600 Hz, which is predetermined as Input to the mixer 93. The mixer 93 mixes the audio signal input from the broadcast microphone 40 by separating it for a short time, switching to the input of the emergency information control data signal from the data modulator 91, and inserting the mixed signal, and the mixed signal is mixed by the microphone connection circuit unit 96. The mixed signal is voice-encoded by the voice input unit 28, and the mixed signal is voice-encoded by the voice input unit 28 and transmitted from the antenna 34 as a notification signal according to the first wireless communication protocol by the wireless communication unit 32. As the mixer 93, in addition to switching and mixing the inputs of the two audio signals, an appropriate mixing circuit such as adding and synthesizing the two audio signals and mixing them can be used.

Here, the emergency information control data signal to be mixed with the audio signal by switching the mixer 93 requires only 100 msec if the communication speed is 2400 bps even when sending data having a length of 200 bits, for example, and during this period, the audio signal is generated. Even if it is cut off, since the time is extremely short, it does not interfere with the voice content when the voice signal is reproduced and notified by, for example, the loudspeaker station 16 on the terminal side.

By simply connecting the communication data generator 87 between the microphone jack terminal 94 of the console 14 and the broadcasting microphone 40 in this way, the report control content can be adjusted with almost no improvement or repair on the master station 12 side. By operating any of the corresponding operation switches 89a to 89n, it is possible to send the necessary control data signal for emergency information notification to the Smoke Detector side and output the notification, making it easy for existing equipment. I can handle it.

[Disaster prevention warning cooperation system using community FM broadcasting]
(System overview)
FIG. 17 is an explanatory diagram showing a disaster prevention alarm cooperation system according to another embodiment of the present invention in which a community FM broadcasting station and a resident guard are combined.

In FIG. 17, the community FM broadcasting station 400, which serves as a broadcasting facility, is a broadcasting station whose broadcasting target area is a geographical community, and a part of the area within the administrative district of a municipality or an ordinance-designated city is defined as a broadcasting area. To do. The broadcasting frequency uses a frequency in the VHF (Very High Frequency) broadcasting band (76.0 to 90.0 MHz), FM (Frequency Modulation) is used as the modulation method, and it can be listened to by a commercially available FM compatible radio. The receiving area having an antenna power of 1 W or less has a radius of about 2 to 3 km, the receiving area having an antenna power of 10 W or less has a radius of about 5 to 10 km, and the receiving area having an antenna power of 20 W or less has a radius of about 15 to 20 km.

The community FM broadcasting station 400 is connected to the headend 402, the national instantaneous alarm system receiver 404 and the municipal disaster prevention console 406 are connected to the headend 402, and the emergency alert receiver 15 is connected to the municipal disaster prevention console 406. are doing.

The national instantaneous warning system, known as J-ALERT, uses communication satellites to instantly provide information necessary for the protection of the people in the event of a large-scale disaster or armed attack situation. It is a system that transmits emergency information to residents by automatically activating the broadcast-type municipal disaster prevention administrative radio connected to the regional satellite communication network while transmitting it to the group.

The information transmitted by the National Instant Alert System is roughly divided into weather-related information and emergency-related information, and 23 types of information are transmitted. Municipalities can decide which information to automatically activate the broadcast-type municipal disaster prevention administrative radio, but in principle, automatic activation is required for earthquake early warnings, large tsunami warnings, tsunami warnings, eruption warnings, and emergency-related information. Has been done.

When distributing information, the national instantaneous warning system transmits an information number that identifies the type of information and regional target code information together with the broadcast content.

When the national instantaneous warning system receiver 404 of the present embodiment receives an Earthquake Early Warning, a large tsunami warning, a tsunami warning, etc., it demodulates the broadcast content including the information number and the regional target code information and heads it as an emergency information notification signal. Output to end 402.

The headend 402 receives the emergency information notification signal output from the national instantaneous warning system receiver 404, and for example, for earthquake early warnings, large tsunami warnings, and tsunami warnings, the automatic selection of broadcast contents and the filtering function of automatic distribution are provided. If it is set and the received regional target code information matches the preset regional target code information, the broadcast content is selected, and an emergency information notification signal with at least the information number added to this broadcast content is generated. Deliver to community FM broadcasting station 400.

The community FM broadcasting station 400 FM-modulates and transmits an emergency information notification signal including, for example, an earthquake early warning, a large tsunami warning, or a tsunami warning broadcast content and information number delivered from the headend 402.

A relay adapter 500 is installed outdoors, which is the target area of the community FM broadcasting station 400, and one or more housing police 100s are installed in the house 24, which is an area where signals relayed from the relay adapter 500 can be received. There is. Since the relay adapter 500 requires an AC power source, for example, as in the embodiment of FIG. 1, when the municipal disaster prevention radio equipment 10 is installed, the relay adapter 500 is installed in the vicinity of the loudspeaker station 16, for example, on a support column to make the loudspeaker louder. The AC power supply of the slave station 16 is used as it is to simplify the equipment configuration.

When the relay adapter 500 receives the emergency information notification signal transmitted from the community FM broadcasting station 400, the relay adapter 500 decodes the information number contained therein and uses the second wireless communication protocol on the side of the Smoke Detector 100 corresponding to the information number. It is converted into an Earthquake Early Warning interlocking signal, a large tsunami warning interlocking signal, or a tsunami warning interlocking signal and transmitted to the Smoke Detector 100, and the Earthquake Early Warning is sent from the Smoke Detector 100 by a predetermined warning voice message. , A large tsunami warning or a tsunami warning is output.

Here, the group code included in the interlocking signal transmitted from the relay adapter 500 according to the second wireless communication protocol is set to a common group code that enables effective reception by all the Smoke Detector 100, and there is no so-called group designation. It is an interlocking signal of.

The voice message output from the Sumitomo Police 100 is a combination of an alarm sound and voice broadcasting. In the case of an Earthquake Early Warning, for example, "Kyun Kyun is a big earthquake", and in the case of a big tsunami warning, for example, "Woo Woo big tsunami warning". Was announced. Please evacuate to high ground if you are near the coast. "In the case of a tsunami warning, for example," Woo Woo Tsunami warning was announced. Please evacuate to high ground if you are near the coast. " ..

In addition, when the municipal disaster prevention operation console 406 receives information other than the information set for automatic activation distribution on the headend 402 by the national instantaneous alarm system receiver 404, the staff in charge of the municipality performs a distribution instruction operation as necessary. Then, the distribution instruction signal is output to the head end 402. Upon receiving this distribution instruction signal, the headend 402 distributes an emergency information notification signal including the broadcast content and information number received from the national instantaneous warning system receiver 404 to the community FM broadcasting station 400, and puts it on the FM radio wave. Send it.

Further, in the present embodiment, an emergency information receiving device 15 is provided for the municipal disaster prevention operation console 406 in order to perform an automatic test of the disaster prevention alarm cooperation system. The emergency information receiving device 15 reproduces and outputs a broadcast signal when it detects the reception of an emergency warning broadcast (EWS) or an earthquake early warning (EEW), which is an emergency information broadcast, and also outputs a broadcast signal to the test signal of the emergency warning broadcast (EWS). When reception is detected, a test report signal is automatically output.

Emergency warning broadcasting (EWS) 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 the TV or radio receiver in the standby state. Although it is turned on, a test signal is transmitted once a month at a predetermined time, for example, at noon on the first day of every month in order to confirm the operation of the receiver, and this test signal is received by the emergency information receiving device 15. Test the disaster prevention alarm cooperation system by outputting the test report signal.

For example, in the case of NHK (R), emergency information is received because only the end signal is transmitted without transmitting the type 1 start signal or type 2 start signal as a test signal at noon on the first day of every month. The device 15 outputs a test notification signal based on the reception of only the end signal.
The test report signal output from the emergency alarm receiving device 15 is transmitted to the headend 402 via the municipal disaster prevention operation console 406, and the headend 402 that receives the test report signal has a predetermined information number indicating the system test. A test report signal including the content of the test broadcast is generated, distributed to the community FM broadcasting station 400, and the test report signal is FM-modulated and transmitted.

The test report signal transmitted from the community FM broadcasting station 400 is received by the relay adapter 500, and the relay adapter 500 decodes the information number included in the received test report signal to recognize the system test, and the Smoke Detector 100 side. It is converted into a test interlocking signal according to the second wireless communication protocol and transmitted to the Smoke Detector 100, and the test disaster prevention information is broadcasted and output from the Smoke Detector 100.

Here, the group code included in the test interlocking signal transmitted from the relay adapter 500 according to the second wireless communication protocol is set to a common group code that enables effective reception by all Smoke detectors, and there is no so-called group designation. It is an interlocking signal of.

The notification output of the test disaster prevention information by the Smoke Detector 100 is caused by lighting, blinking, or blinking the LED 122 for a predetermined time. In addition, when the alarm device 100-1 detects the on operation of the alarm stop switch 120 while the LED 122 is operating, it repeatedly notifies a voice message such as "A peepy emergency alarm test is performed. An emergency alarm has been issued." Output. The test disaster prevention information is performed by setting a volume lower than the actual alarm volume to reduce power consumption.

Further, each time the Smoke Detector 100 receives the test interlocking signal, it continuously counts the number of times N for which there is no notification output by the voice message of the test disaster prevention information, and the continuous number of times N reaches a predetermined threshold number Nth. In this case, the test disaster prevention information is notified and output by a voice message.

Each disaster prevention information or test disaster prevention information notified and output from the Smoke Detector 100 is stopped, for example, after a predetermined time has elapsed or after a predetermined number of notifications.

Further, when the Smoke Detector 100 receives the test interlocking signal from the relay adapter 500, the Smoke Detector 100 transmits a test interlocking signal in which the group code to which the Smoke Detector 100 belongs is set to another Smoke Detector 100 located in the same house. Interlocking tests will be conducted to output test disaster prevention information from other Smoke Detectors 100 belonging to the same group.

The National Instant Alert System (J-ALERT) provides test broadcasts and training broadcasts as needed, but like the Emergency Warning System (EWS), test broadcasts are conducted on a regular basis. At present, it cannot be used for regular system tests, but when the National Instant Alert System (J-ALERT) regularly broadcasts tests, the tests received by the National Instant Alert System Receiver 404 The broadcast information number may be determined by the headend 402 and a similar system automatic test may be performed. In this case, the emergency alarm receiving device 15 becomes unnecessary.

If necessary, it is also possible to output a test report signal to the headend 402 by a test operation using the municipal disaster prevention operation console 406 to perform an automatic system test.
