Abstract

PROBLEM TO BE SOLVED: To provide a capability of surely obtaining disaster prevention information such as an occurrence of an earthquake or the approach of a tsunami even in a room that is not provided with an emergency warning device or a place having a bad reception environment for broadcasting radio wave by cooperation with an alarm unit.SOLUTION: An emergency warning device 100 detects an emergency information signal such as an emergency earthquake prompt report, an emergency warning, or a tsunami warning from AM broadcast, FM broadcast or TV broadcast, outputs an alarm and transmits a cooperation signal based on the emergency information signal to house alarm devices 10-1 to 10-5. If the house alarm devices 10-1 to 10-5 detects an abnormality of the alarming area, it outputs an alarm of abnormality, and if it receives from an emergency information device a cooperation signal based on an emergency information signal, it outputs a disaster prevention information corresponding to the cooperation signal.

Description

The present invention relates to a disaster prevention alarm linkage system, a disaster prevention alarm linkage method, an alarm device, and an emergency warning device that output a disaster prevention alarm such as an earthquake or tsunami using an alarm device that detects and alarms such as a fire or gas leak. .

  2. Description of the Related Art Conventionally, alarm devices that detect and warn of abnormalities such as fires and gas leaks in homes are widely used. 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. is 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, as an earthquake warning system that notifies earthquake information using TV broadcasting, FM broadcasting, and AM broadcasting, emergency warning broadcasting is performed when a large-scale disaster such as an earthquake occurs or when a tsunami warning is announced. There is also an emergency earthquake bulletin that announces predictions for areas where strong shaking is expected before the shaking arrives in the event of an earthquake.

  Emergency warning broadcasts are broadcast via TV, FM and AM broadcasts when a Tokai earthquake warning declaration is issued, when a tsunami warning is announced, or when an evacuation instruction is issued by the governor or the head of the local government. An emergency alert signal is transmitted to automatically turn on the receiver, and the emergency alert broadcast is reproduced and output.

  In addition, the earthquake early warning will be announced at an estimated maximum seismic intensity of 5 or less, and an earthquake early warning signal will be transmitted by TV, FM and AM broadcasts, and a serious disaster will occur in areas where strong shaking is expected due to earthquake motion Warning that there is a risk.

  Emergency warning devices that function as dedicated receivers in response to such emergency warning broadcasting and earthquake early warnings have been put into practical use and are widely used.

  For example, in an emergency warning device corresponding to an earthquake early warning, for example, a specific FM radio broadcast is selected and is in a reception standby state. "Please be wary of strong shaking" twice, for example, the first chime sound is analyzed, the earthquake early warning signal is detected, the broadcast playback operation is started, and the automatic sound following the chime sound Is output from the speaker at the set volume to notify the occurrence of an earthquake.

  Further, in the case of an emergency warning broadcast of analog broadcasting, the emergency warning device corresponding to the emergency warning broadcast detects an FSK signal which is an electronic sound (piropiro sound) in the audible range first transmitted as a start signal. In such a case, a broadcast reproduction operation is started to receive and reproduce emergency warning broadcasts such as tsunami warnings.

Furthermore, an emergency warning device corresponding to both emergency earthquake warning and emergency warning broadcasting has been put into practical use.

  However, in such an emergency warning device that detects and automatically reproduces the reception of such emergency earthquake warnings and emergency warning broadcasts, the earthquake early warning and tsunami warning can only be heard within the range where the sound from the emergency warning device can be heard. However, it is necessary to install an emergency warning device for each room. However, there are problems that the cost is high and installation spaces must be secured in various places.

  In addition, since the emergency warning device is basically a receiver for television broadcasting, FM broadcasting, AM broadcasting, etc., depending on the room, radio wave conditions may be poor and radio waves may not be received with sufficient strength. There is a possibility that even if installed in a place, it does not function effectively.

The present invention makes it possible to know disaster prevention information such as the occurrence of an earthquake or tsunami even in a room where an emergency warning device is not installed or a place where the broadcast radio wave reception environment is not good, in cooperation with an alarm device. It aims at providing a disaster prevention alarm cooperation system, a disaster prevention alarm cooperation method, an alarm device, and an emergency warning device.

The block diagram which showed other embodiment of the emergency warning device provided in the warning cooperation system of FIG. 1 which receives AM broadcast

  FIG. 1 is an explanatory view showing a schematic configuration of a disaster prevention alarm linkage system according to the present invention in which an alarm system installed in a house and an emergency warning device are linked.

  In the example of FIG. 1, a wireless dwelling device that detects and interlocks with a fire in each of the warning areas of the kitchen, living room, master bedroom, children's room, and staircase provided in the house 24 ( Residential fire alarms) House alarms 10-1 to 10-5 are installed, and an interlocking alarm system is constructed. In addition, the house alarm devices 10-1 to 10-5 are collectively referred to as the house alarm device 10 without being distinguished from each other.

  The home alarm device 10 has a function of wirelessly transmitting and receiving interlocking signals to each other, and monitors the presence or absence of a fire in the corresponding monitoring area in each place of the house. If a fire should occur in the living room 24, the home alarm device 10-1 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 10-1 issues a report, the home alarm device 10-1 functions as an interlocking source, and in accordance with a predetermined wireless communication protocol with respect to the other residential alarm devices 10-2 to 10-5 that become the interlocking destination. A fire-linked signal is transmitted wirelessly. When the other home alarm devices 10-2 to 10-5 have received the fire interlock signal from the home alarm device 10-1 of the interlocking source effectively, the alarm operation as the interlocking 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 resident alarm 10 confirms that the interlocking signal has been effectively received. I try to detect it. Furthermore, the resident guard 10 that has effectively received the interlocking signal relays the interlocking 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 device 10-1 that is the interlock 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 interlocking home alarm devices 10-2 to 10-5 output a fire alarm sound with a voice message such as “Please confirm that another fire alarm device has been activated”.

  Moreover, as an alarm display accompanying the fire alarm of the residence police device 10-1 which became the interlocking source, for example, an LED is lit. On the other hand, in the interlocking residence police 10-2 to 10-5, 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 devices 10-1 to 10-5 are emitting an alarm sound, the alarm sound and alarm display stop processing is performed. At this time, for example, when the alarm stop operation is performed in the home police device 10-1 that is the interlocking source, the alarms of all the home police devices 10-2 to 10-5 are stopped, and the home police that is the interlocking destination is stopped. When an alarm stop operation is performed in any of the devices 10-2 to 10-5, the alarm of the interlocking home police device 10-1 is not stopped, and the interlocking destination home police devices 10-2 to 10-10 Stop -5 alarm.

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

  On the other hand, the emergency alert device 100 is installed in the living room where the broadcast radio wave environment is good, for example, in the living room. The emergency warning device 100 receives a broadcast signal transmitted as FM broadcast, TV broadcast (digital TV broadcast) or AM broadcast, and when the emergency information signal is detected by analyzing the broadcast signal, the emergency information is reproduced. Output sound.

  Emergency information broadcasts received and reproduced by the emergency warning device 100 include emergency earthquake warning (EEW) and emergency warning broadcasting (EWS). The earthquake early warning is a warning issued by the Japan Meteorological Agency with an estimated maximum seismic intensity of less than 5 for the general public, and warns that there is a possibility of serious disasters due to earthquake motion to areas where strong shaking is expected Broadcast. For example, “Earthquake early warning (2 times chime sound). Watch out for strong shaking” is repeated twice. For example, the emergency warning device 100 analyzes the first chime signal to detect an emergency earthquake warning signal and switches from the reception standby state to the reproduction operation, and “Emergency earthquake warning. Be wary of strong shaking.” Output at the set volume.

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

  In the following explanation, when the earthquake early warning, tsunami warning and emergency warning are collectively expressed, it is called emergency information, and the signals representing these are called emergency earthquake early warning signal, tsunami warning signal and emergency warning signal, When collectively expressed, it is called an emergency information signal.

  The emergency alarm device 100 used in the present invention receives a broadcast signal transmitted as FM broadcast, TV broadcast (digital TV broadcast) or AM broadcast, and analyzes this to analyze an earthquake early warning signal and a tsunami warning signal. Alternatively, when reception of an emergency warning signal is detected, broadcast sound is reproduced and output.

  Further, in the present invention, since the emergency warning device 100 is linked to the residential alarm 10 provided in the warning system, the emergency warning device 100 detects the reception of the emergency earthquake warning signal, the tsunami warning signal, or the emergency warning signal. In this case, a cooperative signal based on the emergency earthquake warning signal, a cooperative signal based on the tsunami warning signal, or a cooperative signal based on the emergency warning signal is generated and transmitted in accordance with the same wireless communication protocol as that of the home alarm device 10.

  Here, in the following description, the cooperation signal based on the earthquake early warning, the cooperation signal based on the tsunami warning, or the cooperation signal based on the emergency warning will be referred to as the emergency earthquake warning cooperation signal, the tsunami warning cooperation signal, or the emergency warning cooperation signal, respectively.

  Moreover, it is as follows when the relationship of the signal in the disaster prevention alarm cooperation system of this invention is arranged. First, the case where the housing alarms are linked in the alarm system is called “linkage”, and the case where they are linked by a signal from the emergency warning device 100 other than the alarm system is called “linkage”.

  In addition, a signal transmitted and received between the housing alarms 10 within the alarm system is referred to as a “link signal”, and a signal transmitted from the emergency alarm device 100 outside the alarm system to the housing alarm 10 is referred to as a “cooperation signal”. The former interlock signal includes a fire interlock signal, a fire recovery interlock signal, an alarm stop interlock signal, and a failure interlock signal. The latter interlock signal includes an emergency earthquake warning alert signal, a tsunami alert alert signal, and an emergency alert alert signal. .

  The residential alarm 10 that constructs an alarm system corresponding to the cooperation function of the emergency warning device 100 receives the emergency earthquake warning signal, the tsunami warning signal, or the emergency warning signal transmitted from the emergency warning device 100. And when this is decoded and effective reception is detected, predetermined disaster prevention information is notified and output corresponding to each.

  For example, “Peep emergency earthquake bulletin. Please be wary of strong shaking.” When the emergency warning device 100 detects the effective reception of the earthquake early warning linkage signal from the emergency warning device 100, the Dwelling Guard 10 is prepared as disaster prevention information corresponding to the earthquake early warning. And the LED is turned on, for example.

  Moreover, when the tsunami warning device 10 detects the effective reception of the tsunami warning linkage signal from the emergency warning device 100, the disaster prevention information corresponding to the tsunami warning is issued, for example, "Phi Tsunami warning has been issued. The voice message such as “Please evacuate to the hill” is repeatedly outputted and the LED is turned on, for example.

  Furthermore, when the home alarm device 10 detects the effective reception of the emergency alert linkage signal from the emergency alert device 100, the disaster warning information corresponding to the emergency alert, for example, “Peep emergency alert has been issued” is repeated repeatedly. A notification is output and the LED is turned on, for example.

  Each disaster prevention information that is notified and output from the home alarm device 10 stops after a predetermined time has elapsed or after a predetermined number of notifications.

  2A and 2B are explanatory views showing the appearance of a wireless interlocking smoke-type home alarm used in the present invention. FIG. 2A shows a front view and FIG. 2B shows a side view. The side provided with the attachment hook 15 is the upper side.

  In FIG. 2, the housing of the residential alarm 10 according to the present embodiment includes a cover 12 and a main body 14. A protrusion is provided at the center of the cover 12, a plurality of smoke inlets are opened around the protrusion, and a smoke detector 16 is disposed inside the protrusion, so that smoke accompanying a fire flows into the smoke detector 16. When a predetermined concentration is reached, a fire is detected by an alarm control unit described later. As the smoke detector 16, for example, a known scattered light smoke detector mechanism can be applied.

  An acoustic hole 18 is provided on the lower left side of the cover 12, 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 20 is provided below the cover 12.

  The alarm stop switch 20 is configured to press a built-in push switch (not shown) when a switch cover formed of a translucent member is pressed. An LED 22 for displaying an alarm or the like is disposed near the push switch inside the switch cover.

  The alarm stop switch 20 also functions as an inspection switch that instructs the self-inspection of the function of the home alarm 10 from the outside. For example, when the alarm stop switch 20 is operated during the fire alarm output, the fire alarm is stopped, and when the alarm stop switch 20 is operated in a normal state, a self-inspection is performed for a predetermined function, and the result is obtained by the LED 22 or a speaker. Is notified. Here, the normal state refers to a state where at least a fire alarm is being output or a failure alarm is not being output.

  Further, a mounting hook 15 having an insertion hole in the substantially central portion thereof is provided at the upper part on the back side of the main body 14, and a screw or the like is screwed into a wall surface or the like of a room to be installed and hooked through the insertion hole of the mounting hook 15. Thus, the residential alarm 10 can be fixedly installed on the wall surface in a so-called wall-hanging manner.

  FIG. 3 is a block diagram showing an embodiment of an emergency alarm device and a residential alarm provided in the alarm 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. Moreover, in FIG. 3, although it has shown about the residence guard 10-1 installed in the living room 24, in the case of this embodiment, it becomes the same structure also about other residence guards 10-2 to 10-5.

  In FIG. 3, first, the residential alarm 10-1 will be described. The home alarm device 10-1 is provided with a processor 28 known as a one-chip CPU. A wireless communication unit 30, a memory 32, a sensor unit 34, and a notification unit 36 that transmit and receive a predetermined wireless communication protocol to the processor 28 are provided. The operation unit 38 and the battery power source 40 are provided, and the battery power source 40 supplies power to necessary units.

  The wireless communication unit 30 includes a transmission circuit 42 and a reception circuit 44 and is connected to the antenna 31. The wireless communication unit 30 is connected to the other residential alarm devices 10-2 to 10-5 via the antenna 31 in accordance with a wireless communication protocol conforming to the standard of a specific low power wireless station in the 400 MHz band, for example. Various linkage signals such as recovery, alarm stop, and failure are transmitted and received, and various linkage signals from the emergency warning device 100 are received.

  The transmission of the interlocking signal by the wireless communication protocol in the transmission circuit 42 of the wireless communication unit 30 is performed by performing an operation of transmitting the interlocking signal for a predetermined time T1, for example, T1 = 3 seconds, and a pause time of the predetermined time T2, for example, T2 = 2 seconds. Repeated 4 times, for example. 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.

  In addition, reception by the wireless communication protocol in the reception circuit 44 of the wireless communication unit 30 is received from an interlocking signal or an emergency warning device from the other residential alarm devices 10-2 to 10-5 belonging to the same group as the residential alarm device 10-1. Intermittent reception of linked signals. 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.

  The received signal is decoded by the cooperation destination control unit 60 provided in the processor 28. 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.

  Further, in the wireless communication protocol of the wireless communication unit 30, the resident guard 10-1 itself detects a fire or an event other than a fire and transmits an interlocking signal, or receives a cooperation signal from the emergency warning device 100 and others. When transmitting to the other home alarm device, it indicates that the interlocking signal has been normally received from the other home alarm devices 10-2 to 10-5 which belong to the same group as the home alarm device 10-1 and have received it. It is monitored whether or not an acknowledgment signal (hereinafter referred to as “ACK signal”) is effectively received.

  When the other ward alarm device that does not receive the ACK signal is detected, the resident alarm device 10-1 transmits the interlock request signal or the linkage signal with the relay request to the other resident alarm device that has received the ACK signal. Then, the relay signal with the relay request is relay-transmitted from the home alarm device that has received the relay signal with the relay request or the link signal to the home alarm device with no AKC signal response. An ACK signal that has not received an AKC signal that has received a relay signal or link signal with a relay request returns an ACK signal to the link signal or link signal with a relay request. (Reply relay) is received by the home guard 10-1 of the interlocking source. 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.

  As shown in FIG. 4, the interlocking signal 46 transmitted and received by the wireless communication protocol of the wireless communication unit 30 is configured as a format including a serial number 48, a transmission source identification code 50, a group code 52, and an event code 54. The serial number 48 is a code that is generated independently for each home alarm, and is a serial number that indicates the generation order or transmission order of the interlocking signal 46. Based on this, management such as prohibition of re-relay can be performed. The transmission source identification code 50 is, for example, a serial number of a residential police device that identifies each residential police device, and the group code 52 is a group of residential police devices 10-1 to 10-5 installed in the house 24 as shown in FIG. It is the code | symbol for comprising the interlocking | linkage group which mutually interlock | cooperates within.

The event code 54 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, the cooperation signal transmitted from the emergency warning device 100 has the same format configuration as the cooperation signal 46 shown in FIG. 4, and as an event code corresponding to the cooperation 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 relaying residence policer are added to the linkage signal or linkage signal to be relayed. 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 34 is provided with a smoke detector 16 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 36 is provided with a speaker 58 that is an acoustic output device that outputs an alarm sound and the like, and an LED 22 that performs alarm display and the like along with respective drive circuits (not shown). Under the control of the cooperation destination control unit 60, the speaker 56 outputs a voice message, an alarm sound, or the like based on various data stored in the memory 32 or the like by the residence guard 10-1. The LED 22 notifies an abnormality or other event such as a fire by a display by blinking, blinking, or lighting.

  The operation unit 38 is provided with an alarm stop switch 20. The alarm stop switch 20 functions as an alarm stop switch only when a fire or fault alarm sound is output from the notification unit 36 through the speaker 56 or when an alarm display is performed through the LED 22. For example, if the alarm stop switch 20 is operated during an alarm indicating the interlock source, the alarm sound and the alarm display are stopped. On the other hand, if the alarm stop switch 20 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 20 functions as an inspection switch. When the alarm stop switch 20 is operated in this state, a predetermined self-inspection operation is executed. Then, a voice message indicating the inspection result is output from the notification unit 36.

The memory 44 stores a serial number 48, an identification code 50, a group code 52, and the like used for generating the interlocking signal.

  The battery power supply 46 uses, for example, a lithium battery or an alkaline battery having a predetermined number of cells, and supplies power to necessary parts. As a battery capacity, for example, a lifetime of 10 years is guaranteed by reducing the power consumption of the entire circuit unit in the residence guard 10-1.

  The processor 28 is provided with the function of the cooperation destination control unit 60 as a function realized by executing the program.

The processor 102 is provided with a cooperation source control unit 124 as a function realized by executing the program.

  The FM receiver 104 tunes the tuner to the FM station selected by the operation of the operation unit 114, receives the broadcast radio wave by the FM antenna 106, demodulates the broadcast signal, and outputs it as an audio signal. The audio amplifying unit 108 stops operating in a standby state, and therefore, the FM broadcast received from the speaker 110 is not reproduced and output.

  When the effective reception of the emergency earthquake warning signal, tsunami warning signal, or emergency warning signal is detected by the analysis processing of the cooperation source control unit 124 provided in the processor 102, the voice amplification unit 108 is switched to the operating state. The broadcast content of the emergency earthquake warning signal, tsunami warning signal, or emergency warning signal that has been reproduced and output is reproduced and output from the speaker 110. The display unit 112 performs various displays necessary for FM broadcast reception such as standby reception display, emergency earthquake warning reception display, tsunami warning reception display, emergency warning reception display, and channel selection frequency display.

  The wireless communication unit 118 is provided with a transmission circuit 122 so that various cooperation signals can be transmitted from the antenna 120 to the home guards 10-1 to 10-5. As for the wireless communication protocol of the wireless communication unit 118, in the case of Japan, as in the case of the residential alarm 10, for example, STD-30 or STD-T67 known as a standard of a specific low power wireless station in the 400 MHz band.

It is operated for a predetermined time to control the tsunami warning broadcast to be reproduced and output from the speaker 110. Further, when receiving and analyzing 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, the operation of the audio amplifying unit 108 is stopped based on this and the speaker 110 is stopped. You may make it perform control which stops the output of broadcast sound.

  Further, the analysis and detection of the emergency warning signal by the cooperation source control unit 124 analyzes and detects the effectiveness of the first type start signal that flows during the first 10 seconds of the emergency warning signal. The emergency alarm broadcast is reproduced by operating for a predetermined time and is output from the speaker 110.

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

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

  When the cooperation source control unit 124 receives and analyzes the emergency earthquake warning signal, the tsunami warning signal, or the emergency warning signal as described above, it operates the voice amplification unit 108 to reproduce the broadcast sound at that time, and the speaker 110 The emergency earthquake warning linkage signal, the tsunami warning linkage signal or the emergency warning linkage signal in accordance with the same wireless communication protocol as the Dwelling Guard 10 is generated, and the wireless communication unit 118 is instructed to send the transmission.
