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 is related with the disaster prevention alarm cooperation system and the alarm device.

  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/tyosakenky/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 receiver for each dwelling unit. However, the installation cost is greatly increased, 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 enables centralized monitoring of disasters such as the occurrence of earthquakes and the arrival of tsunami and abnormalities such as fires detected by alarms by linking two-way communication between local disaster prevention radio equipment and indoor alarms It aims at providing the disaster prevention alarm cooperation system and alarm device .

  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 equipment 10 is a TDMA (Time Division Multiple Access) -TDD (time division multiplexing) that divides one radio carrier into frames and divides the frames into slots corresponding to the number of multiplexing. (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 again to FIG. 1, in this embodiment, has established a relay adapter 200 outdoors the service area of the municipal disaster prevention radio equipment for each service area which is divided according to local conditions, relay adapter 200 For example, it is installed on a column where the loudspeaker slave station 16 is installed.

The relay adapter 200 performs two-way communication with protocol conversion between the master station 12 or the relay station 22 and the home guard 100 provided in the house 24. That is, 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 first alarm signal on the side of the home alarm device 100. 2 Converts to an interlocking signal according to the wireless communication protocol and transmits it. This is called downlink communication. Further, the relay adapter 200 receives a fire cooperation signal according to the second wireless communication protocol that is transmitted when a fire is detected and alarmed by the home alarm device 100, and the fire cooperation signal conforms to the first wireless communication protocol. It converts into a fire cooperation signal and transmits to the master station 12 side. This is called uplink communication.

  In addition to the fire cooperation signal, the cooperation signal transmitted from the home alarm device 100 to the master station side includes a fire recovery cooperation signal accompanying a fire recovery, an alarm stop cooperation signal accompanying an alarm stop operation, a failure cooperation signal accompanying a failure detection, etc. is there.

  The interlock signal transmitted to the home alarm device 100 by downlink communication from the relay adapter 200 includes a common group code. The home alarm device 100 installed in each house 24 receives and decodes the interlock signal. When a common group code is detected, even if it does not match the group code to which it belongs, it effectively receives the interlocking signal from the relay adapter 200 and outputs a notification. 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 a necessary service area as a communicable area depending on the transmission power (1 W or less), 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 outline of the downlink communication path in the embodiment of FIG. Here, what divided the service area is hereinafter referred to as a service area, a service area, or simply an area.

  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.

  FIG. 4 is an explanatory diagram showing an outline of the uplink communication path in the embodiment of FIG. In FIG. 4, when a fire is detected and alarmed by the residential alarm 100 installed in the houses in the service areas A1 to A4, a fire cooperation signal is transmitted to the relay adapter 200, which will be clarified in later explanation. In addition, since the home alarm device 100 conforms to the standard of the specific low-power radio station, the transmission power is 10 mW or less or 1 mW or less, the line-of-sight communication distance is about 100 meters, and the place away from the relay adapter 200 The radio wave from the home security device 100 cannot be received effectively by the relay adapter 200.

  Therefore, in the present embodiment, the fire cooperation signal is relayed in multiple stages by a plurality of residence police devices 100 arranged in the service area and sent to the residence police device 100 arranged in the communicable area with respect to the relay adapter 200. From there, it transmits to the relay adapter 200. In order to enable such multistage relaying by a plurality of residence guards 100, the fire cooperation signal exceeds the interlocking group configured for each house by transmitting it as a signal without group designation with a common address code set. Multi-stage relay is possible.

  In addition, since it is assumed that there are no other residential housing guards in the communicable area of the housing guard 100, in that case, a relay booster, which will be clarified later, is arranged, and the relay booster cooperates with the fire. The upstream communication path to the relay adapter 200 is established by relaying the signal.

  FIG. 5 is an explanation showing an outline of the upstream communication path from the resident alarm to the relay adapter in the service area of FIG. 4. The resident alarms 100-1 to 100-6 are distributed in the service area with respect to the relay adapter 200. Has been placed. Now the fire alarm 1001-1 detects and alerts the fire, and transmits a fire cooperation signal as indicated by a dotted arrow. This fire cooperation signal is relayed in multiple stages by the other home alarm devices 100-2 to 100-6, and finally received by the home alarm device 100-5 which has installed the relay adapter 200 as its own communicable distance. It is transmitted to the adapter 200.

  Such multi-stage relaying by a plurality of home guards 100 is known as multi-hop transmission, and multi-hop transmission is performed by setting the maximum number of hops (maximum number of relays) to a predetermined number, for example, five. In each of the home alarm devices 100, configuration information in which a transmission source code is registered as an ID (identification information) of an adapter capable of communication corresponding to the number of times of relay is stored in advance in a memory, and transmitted to a cooperation signal to be transmitted. Since the transfer source ID and transfer destination ID for relaying are provided in addition to the original ID and the destination ID, the adapter ID that can reach the destination ID from the configuration information with the minimum number of times is sequentially set to the transfer destination ID and linked. Relay signal transmission.

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. I am trying to send it. 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, tsunami warning and emergency warning are collectively expressed, it is called emergency information, and signals representing these transmitted from the master station 12 are the emergency earthquake early warning signal, 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 from the master station 12 according to the first wireless communication protocol, 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 referred to as an emergency earthquake warning interlocking signal, a tsunami warning interlocking signal, and an emergency alert interlocking signal.

  In addition, 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 guard, 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 home alarm device.

  Further, a signal transmitted from the residential alarm 100 that constructs an alarm system indoors to the municipal disaster prevention radio equipment 10 is referred to as a “linkage signal”, and the link signal includes a fire link signal, a fire recovery link signal, an alarm stop link signal, and There is a fault coordination signal.

FIG. 7 is a block diagram showing a schematic configuration of the loudspeaker slave station 16. The loudspeaker slave station 16 uses a processor (computer) as hardware, and is provided with a control unit 46 and a telephone control unit 54 as functions realized by execution of the program, and further connected to the loudspeaker 18 as hardware. Unit 52 and a radio communication unit (first radio communication unit) 58 connected to an antenna 60 that performs radio transmission and reception according to the first radio communication protocol, a power supply circuit unit 55 that generates DC power from AC 100 V and supplies the DC power to each unit, and A standby power supply unit 55a using a secondary battery such as a battery is provided.

A wireless communication unit 58 , an operation unit 48 , and a display unit 50 are connected to the control unit 46, and the control unit 46 inputs and decodes the received data extracted from the slot received and demodulated by the wireless communication unit 58, and receives the received data. When effective reception of audio data (encoded audio signal) is detected, the audio signal is decoded from the audio data, output to the audio output unit 52, amplified to a set level, and output from the loudspeaker 18. The setting level that is amplified by the audio output unit 52 is set to a level that is sufficient for the sound to reach the entire area of the district in charge of the loudspeaker slave station 16 and the broadcast content to be heard. Further, the control unit 46 outputs the transmission data to the wireless communication unit 58 and arranges it in a predetermined slot so as to transmit it to the master station side.

The telephone control unit 54 controls a call connection between the child telephone 56 and a parent telephone provided in the parent station or the like. The wireless communication unit 58 is basically the same as the wireless communication unit 32 of the master station 12 shown in FIG. 6 , but the antenna transmission power is a lower value.

FIG. 8 is a block diagram showing a schematic configuration of the door-to-door receiver 20. The individual receiver 20 uses a processor (for example, a one-chip computer) as hardware, a control unit 62 is provided as a function realized by execution of the program, and a radio that is connected to an antenna 66 that performs radio reception as hardware. A communication unit 64, a display unit 68, an operation unit 70, an IF circuit unit 72 having an IF port 74, and an audio output unit 76 connected to a speaker 78 are provided and are connected to the control unit 62. The power supply unit 80 inputs commercial AC power, converts it into predetermined DC power, and supplies it to each unit, but also includes a battery power source for portable use.

The wireless communication unit 64 has only a reception function according to the first wireless communication protocol, receives and demodulates a notification signal according to the first wireless communication protocol transmitted from the master station 12, extracts a downlink slot, and controls it as reception data To the unit 62. When the control unit 62 decodes the reception data input from the wireless communication unit 64 and detects effective reception of the voice data (encoded voice signal), the control unit 62 decodes the voice signal from the reception data and outputs the decoded voice signal to the voice output unit 76. It is amplified to a predetermined level and a notification is output from the speaker 78.

  Further, when the control unit 62 decodes the received data and detects effective reception of data other than voice, for example, the demodulated data is transferred from the IF circuit unit 72 to a device connected to the IF port 74. The individual receiver 20 basically demodulates and outputs an audio signal. 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.

  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 police 100 is not stopped, but the alarm of the interlocking home police 100-2 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 guard 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. 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. "

  Further, when the home alarm device 100-1 detects the effective reception of the emergency alert interlocking signal from the relay adapter 200, for example, a voice message such as “PPP emergency alert has been issued” is provided as disaster prevention information corresponding to the emergency alert. The notification is repeatedly output and the LED is turned on, for example.

  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.

  Furthermore, when the home alarm device 100 detects a fire, a fire recovery, an alarm stop operation or a failure, it generates a fire cooperation signal, a fire recovery cooperation signal, an alarm stop cooperation signal or a failure cooperation signal with the master station 12 as the destination, Transmit to the relay adapter 200 according to the second wireless communication protocol, or transmit to the relay adapter 200 via multistage relay by other residence guards, and transmit to the master station 12 through conversion to the first wireless communication protocol by the relay adapter 200 To do.

  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 the two is the second wireless communication protocol route 11b. Further, when a fire 101 occurs in the house 24 in the lower right of the figure, the transmission route of the fire cooperation signal from the home alarm device 100 to the relay adapter 200 is the second wireless communication protocol. This is the path 11c.

FIGS. 9A and 9B are explanatory views showing the appearance of a wireless interlocking smoke-type home alarm used in the present invention. FIG. 9A shows a front view and FIG. 9B shows a side view. The side provided with the attachment hook 115 is the upper side.

  In FIG. 9, 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 in the fire alarm output is operated to stop the fire alarm, the alarm stop switch 120 in the normal state is operated to implement the self-inspection for a given function, the result by LED122, a speaker, and the like 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.

  FIG. 10 is a block diagram showing an embodiment of 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.

  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 connected to the other residential alarm 100-2 via the antenna 131 in accordance with, for example, a second wireless communication protocol compliant with the standard of a specific low power wireless station in the 400 MHz band. It transmits and receives various interlocking signals such as recovery, alarm stop, and failure, and receives an emergency earthquake warning interlocking signal, a tsunami alarm interlocking signal, or an emergency alert interlocking signal transmitted from the relay adapter 200 installed outdoors.

  In addition, the second wireless communication unit 130 transmits various cooperation signals such as a fire cooperation signal, a fire recovery cooperation signal, an alarm stop cooperation signal, and a failure cooperation signal to the relay adapter 200 according to the second wireless communication protocol.

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 220 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, the process up to this decoding may be referred to as reception. 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.

The interlocking 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 code 154, a group code 155, and an event code 156, as shown in FIG. Yes. 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 code 154 is, for example, a serial number of the home alarm device that identifies each home alarm device, and the group code 155 is linked to each other within the group of the home alarm devices 100 installed in the house 24 as shown in FIG. It is the code | symbol for comprising an interlocking group.

  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, a transmission source 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 is repeatedly output, and the LED 122 is turned on to perform a fire alarm display indicating the interlock source. In addition, the second wireless communication unit 130 The second transmission circuit 146 is caused to transmit a fire interlocking signal in accordance with a predetermined second wireless communication protocol from the antenna 131 to another house alarm, and further, the second transmission circuit 146 of the second wireless communication unit 130. Is controlled to transmit a fire cooperation signal from the antenna 131 to the relay adapter 200 in accordance with a predetermined second wireless communication protocol.

  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 the effective reception of the fire cooperation 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, the second transmission circuit 146 of the second wireless communication unit 130 is controlled to transmit a fire cooperation signal in accordance with a predetermined second wireless communication protocol from the antenna 131 to the relay adapter 200.

  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. In addition to stopping, the second transmission circuit 148 of the second wireless communication unit 130 transmits a fire recovery interlocking signal to the other home alarm device 100-2 via the antenna 131, and further, the second wireless communication unit 130 Control is performed to cause the second transmission circuit 146 to transmit a fire recovery cooperation signal from the antenna 131 to the relay adapter 200 in accordance with a predetermined second wireless communication protocol.

  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. The fire alarm operation by the output is stopped, the alarm stop interlocking signal is transmitted from the second transmission circuit 148 of the second wireless communication unit 130 to the other residential alarm device 100-2 via the antenna 131, and Control that causes the second transmission circuit 146 of the two wireless communication unit 130 to transmit an alarm stop cooperation signal according to a predetermined second wireless communication protocol from the antenna 131 to the relay adapter 200 is performed.

  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.

  FIG. 19 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. The emergency information control data signal for alerting and outputting the alarm is superimposed on the audio signal and transmitted, so that it is possible to link the resident guard side with almost no improvement or renovation of the equipment used in the municipal disaster prevention radio equipment. It is characterized by doing so.

  In FIG. 19, the master station 12 uses a processor (computer) as hardware, and is provided with a control unit 26, a voice input unit 28, and a telephone control unit 30 as functions realized by execution of the program. A wireless communication unit 32 connected to an antenna 34 that performs wireless transmission and reception according to the first wireless communication protocol is provided, and a database 45 is provided for the control unit 26. For example, the database 45 pre-registers information necessary for anomaly monitoring such as a transmission source code, an address, a telephone number, a family structure, etc., for identifying the home guard 100, using the household number of the service target area as an index. Is the same as the embodiment of FIG.

Are connected to the voice input unit. The broadcasting microphone 40 is connected to the microphone jack terminal 95 of the communication data generator 82. Although the microphone connection circuit 96 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 has a plurality of operation switches 84 a to 84 n connected to the data modulator 86. An emergency information control data signal having a predetermined bit length is assigned to the operation switches 84a to 84n. For example, the operation switch 84a: emergency earthquake alarm control data signal operation switch 84b: tsunami alarm control data signal operation switch 84c: emergency alarm 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 necessary.

  When the data modulator 82 receives an ON signal by the operation of the operation switches 84a to 84n, the data modulator 82 generates an emergency information control data signal composed of a binary code having a predetermined bit length.

The mixer 88 separates the audio signal input from the broadcasting microphone 40 for a short time, mixes it by switching to and inserts the emergency information control data signal from the data modulator 86, and mixes the mixed signal into the microphone connection circuit unit 96. The mixed signal is voice-encoded by the voice input unit 28 and transmitted from the antenna 34 as a report signal according to the first wireless communication protocol by the wireless communication unit 32. As the mixer 88, an appropriate mixing circuit can be used such as adding and synthesizing two audio signals in addition to switching the input of two audio signals and mixing them.

Even if it is refused, since the time is extremely short, for example, when the voice signal is reproduced and notified by the loudspeaker slave station 16 on the terminal side, the voice content is not disturbed.

  In this way, the communication data generator 82 is simply connected between the microphone jack terminal 94 of the console 14 and the broadcasting microphone 40, so that the content of the notification control can be achieved with little improvement or modification on the master station 12 side. By operating any of the corresponding operation switches 84a to 84n, a control data signal for notifying emergency information that is required can be transmitted to the mortgage alarm device and output, and the existing equipment can also be easily obtained. Yes.

The corresponding disaster prevention information is notified and output from the home alarm device 100.

  In the above embodiment, the FSK modulation signal and the MSK modulation signal are exemplified as the digital modulation for modulating the carrier signal in the voice frequency band by the emergency information control data signal (digital signal). However, DTMF (Dual Tone Multi Frequency) is used as an example. ) A combination of modulation and other tones may be used. Of course, other methods may be used, and digital modulation for modulating a carrier signal with a digital signal or analog modulation for modulating a carrier signal with an analog signal may be used. In the case of analog modulation, the carrier signal in the audio frequency band is modulated by the emergency information control signal (analog signal).
