  In such a house alarm, a sensor unit and an alarm unit are integrated in the house alarm, and when a fire is detected by the sensor unit, a fire alarm is output from the alarm unit by voice message, etc. Because it is possible to perform fire monitoring and alarm with a single residence guard without requiring any receiving equipment, it is easy to install and inexpensive, and it is widely used with the mandatory installation in ordinary houses.

  In addition, by communicating between multiple home alarms, when a fire alarm is issued by any home alarm, another home alarm system is also proposed in which other home alarms also issue an alarm. Has been.

  In such a home alarm system, when a fire is detected by the home alarm, the home alarm device that detected the fire is, for example, “Please check that the Woo Woo Fire Alarm has been activated”. A voice message is output. When an alarm is issued by the house alarm, the alarm is stopped by operating an alarm stop switch provided in the house alarm.

  On the other hand, a dedicated emergency earthquake warning device for receiving an earthquake early warning transmitted when an earthquake of a predetermined scale or larger occurs and issuing an alarm is known. The earthquake early warning device, for example, selects a specific FM radio broadcast and is in a reception standby state. After the earthquake early warning broadcasts a predetermined chime sound twice, for example, “Earthquake earthquake broadcast. Be wary of strong shaking.” For example, the first chime sound is analyzed to detect the earthquake early warning signal, the broadcast playback operation is started, and the automatic sound following the chime sound is output from the speaker at a high volume. The occurrence is notified.

  The transmission control unit makes a test notification of an abnormality when the operation of the test switch is detected by the device event detection unit.

  According to the present invention, for example, an earthquake early warning by FM broadcasting is received by a residential monitoring / alarm system including one or more alarm devices that detect an abnormality such as a fire and output an abnormality alarm. By linking the earthquake early warning device to be reproduced, when the earthquake early warning device receives an emergency earthquake early warning by FM broadcasting, an event signal indicating the early earthquake early warning is transmitted to the alarm device in the alarm system, and each received An alarm can notify the occurrence of an earthquake. For example, it is possible to notify an earthquake occurrence in another room where an alarm is installed just by installing an earthquake alert device in one place in a house. However, if a minimum number of units is required, the cost is low, and if an alarm is installed, even if you are in another room, you can be sure of an earthquake and respond immediately.

  In addition, when an alarm such as a fire is detected and an alarm is given, an event signal indicating the abnormality is also sent to the earthquake warning device, so that an abnormality such as a fire can be notified from the earthquake warning device.

  In addition, since the earthquake warning device is linked to the alarm device, the notification area of the earthquake warning device is expanded, so even if the notification target area is outside the notification area from the notification unit provided in the earthquake warning device. As long as it is within the alarm-reportable area of the alarm device, the earthquake warning device can be set up in a location with good radio wave conditions where FM broadcasts can be received well without being confined to its own alert area. It is possible to receive earthquake warnings reliably and notify the occurrence of an earthquake from the earthquake warning device itself and the associated alarm device, and even if an earthquake warning device is installed in a place where no alarm device is installed, the location Can be used to report abnormalities such as fire alarms.

  For example, for alarm devices installed in the same room as the earthquake early warning device, by setting a prohibition mode for event information on the earthquake early warning device side such as emergency earthquake early warning, both the earthquake early warning device and the alarm device are set. Therefore, it is possible to eliminate difficulty in hearing due to the notification of the occurrence of an earthquake, and it is possible to suppress wasteful power consumption by setting the prohibit mode for an alarm device that does not need to output the notification.

  In addition, by operating the test switch provided in the earthquake early warning device, an event signal (device event signal) indicating an emergency earthquake early warning test can be sent to the alarm device, and the emergency early warning test can be performed easily. It is possible to easily perform a warning test of an abnormal alarm with an earthquake warning device. Also, an alarm stop event signal can be sent to stop the alarm of the alarm device.

Explanatory drawing which showed the house which installed the monitoring system by this invention which consists of an earthquake early warning device and a residence guard Explanatory drawing which showed the external appearance of the radio | wireless-type residence guard by this invention FIG. 1 is a block diagram showing an embodiment of a residential alarm and an earthquake early warning device provided in the alarm system of FIG. Explanatory diagram showing the format of the event signal and device event signal used in this embodiment The flowchart which showed the monitoring process by the house alarm of FIG. Flowchart showing the monitoring process of the residential alarm following FIG. Flowchart showing processing by the earthquake early warning device of FIG.

  FIG. 1 is an explanatory view showing an installation state of an alarm system according to the present invention for a house. In the example of FIG. 1, a wireless dwelling alarm (for dwelling) that detects and warns of a fire in each of the vigilance areas of the living room, kitchen, children's room, main bedroom, and staircase provided in the house 24. Fire alarms) 10-1 to 10-6 are installed, and an earthquake early warning device 25 is installed in a corridor with a good FM radio wave environment. Here, the earthquake early warning device 25 corresponds to the earthquake early warning device described in the claims.

  The home alarm devices 10-1 to 10-6 have a function of transmitting and receiving event signals to each other wirelessly, and monitor each warning area. Here, six units monitor the fire of the entire house. If a fire has occurred in the kitchen of the house 24, the home alarm device 10-2 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 10-2 issues a report, the home alarm device 10-2 functions as an interlocking source, and a fire occurs to the other residential alarm devices 10-1, 10-3 to 10-6 that are the interlocking destination. An event signal indicating is transmitted by radio. When the other home alarm devices 10-1, 10-3 to 10-6 receive an event signal indicating the occurrence of a fire from the home alarm device 10-2 of the interlocking source, the alarm sound and the alarm display are used as the interlocking destination. The alarm action is performed.

  Self-events (referred to as alarm events) detected by the home alarm include not only the above-mentioned fire occurrence but also fire restoration, alarm stop operation, emergency earthquake warning and emergency earthquake warning test stop, etc. The reception of various event signals from other alarm devices and devices is also included. These will be described later.

  As an alarm operation of the home alarm device 10-2 that is the link source, for example, an alarm sound by a voice message such as “Please confirm that the Woo Woo fire alarm has been activated” is output. On the other hand, in the interlocked home alarm devices 10-1, 10-3 to 10-6, an alarm sound is output by a voice message such as “Please confirm that another fire alarm has been activated”.

  Moreover, as a display (referred to as an alarm display) associated with an alarm of the residence police device 10-2 that is the interlocking source, for example, an LED 22 (described later) is lit. On the other hand, the LED 22 is blinked in the interlocked residence police 10-1, 10-3 to 10-6. As a result, the alarm display by the LED 22 in the interlock source alarm and the interlock destination alarm can be distinguished.

  It should be noted that the interlocking source LED 22 may be blinking and the interlocking destination LED 22 may be blinking, or the same LED 22 may be blinking, 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, a two-color LED capable of emitting both red and yellow by combining two LEDs can be adopted.

  When the alarm stop switch 20 (described later) is operated in a state in which the house alarm devices 10-1 to 10-6 are outputting an alarm sound, the alarm sound and the alarm display stop process are performed.

  At this time, for example, when the alarm stop operation is performed in the home police device 10-2 which is the interlocking source, all the home police devices 10-1 to 10-6 (hereinafter referred to as the home police devices 10-1 to 10-). 6 are collectively referred to without distinction, the alarm (output of alarm sound and / or alarm display output) of the home alarm device 10) is stopped, and the home alarm devices 10-1, 10-3 to 10 to be linked are stopped. When the alarm stop operation is performed at any of −6, the alarm of the residential alarm device 10-2 is not stopped and the alarm of the residential alarm devices 10-1, 10-3 to 10-6 is stopped. To. Moreover, you may enable it to perform alarm stop operation of an alarm similarly from the emergency earthquake warning apparatus 25 demonstrated below.

  The earthquake early warning device 25 detects, for example, an emergency earthquake early warning signal by FM broadcasting as its own event, reproduces and outputs it, and transmits an event signal indicating the early earthquake early warning to the dwelling guard 10. Here, the event detected by the earthquake early warning device 25 corresponds to the device event described in the claims. Events detected by the earthquake early warning device include operation of an operation unit, reception of an event signal from the resident guard 10, and the like in addition to the above-mentioned earthquake early warning signal reception. An event signal transmitted by the earthquake early warning device is referred to as a device event signal.

  The earthquake early warning device 25 detects and reproduces an emergency earthquake early warning signal by FM broadcasting, and wirelessly transmits an event signal indicating the emergency earthquake early warning to the alarm device 10. Here, the earthquake early warning by FM broadcasting repeats “(Two chime sound) emergency earthquake early warning. Be wary of strong shaking” twice. When the first chime sound signal is analyzed and the reception of the earthquake early warning signal is judged and detected, the reception standby state is switched to the playback operation, and the following "Earthquake early warning. Be wary of strong shaking." Output from the speaker at the set volume.

  In response to the installation of the earthquake early warning device 25, the residential alarm device 10 of the present embodiment receives the device event signal indicating the emergency earthquake early warning from the emergency earthquake early warning device 25, and the information indicating the emergency earthquake early warning as a voice message. Output. As a voice message indicating information indicating the earthquake early warning, for example, “PPP emergency earthquake early warning. Be wary of strong shaking”.

  In addition, when the earthquake early warning device 25 receives an event signal indicating a fire from the home alarm device 10, it outputs an alarm sound indicating a fire. The fire warning sound of the earthquake early warning device 25 is, for example, a voice message such as “Please confirm that the Woo fire alarm has been activated”. The earthquake early warning device 25 may display a fire by turning on, blinking, or blinking the LED together with a fire alarm sound.

  If the event signal includes an identification code (ID) that identifies the home alarm device, the emergency earthquake warning device 25 decodes it and the voice message content tells which of the home alarm devices 10 has issued a fire alarm. Or display content. As described above, the interlocking home alarm system does not have a dedicated receiver, but in this way, the emergency earthquake warning device 25 is used as a device that plays the role of a fire receiver in a so-called fire alarm facility. This makes it possible to collectively manage the fire monitoring network of the house alarm.

  The earthquake early warning device 25 is provided with a test switch, and when the test switch is operated, a device event signal indicating an emergency earthquake early warning test is transmitted. And the information which shows an emergency earthquake bulletin test is alert | reported by the voice message etc. from the resident guard 10 which received this. An example of a voice message that reports information indicating an earthquake early warning test is “Peepy Earthquake Early Warning test.

  When the test switch of the earthquake early warning device 25 is operated, a fire alarm notification test of the earthquake early warning device 25 itself is performed, and for example, a voice test message such as “Woo-woo fire test” is output.

  In other words, in the present embodiment, when the test switch of the earthquake early warning device 25 is operated, a device event signal indicating the emergency earthquake early warning test is transmitted to the home alarm device 10 to test the emergency earthquake early warning, and the emergency The earthquake warning device 25 itself performs a fire alarm test. In this way, the emergency earthquake warning device 25 can perform the earthquake early warning interlocking to the home alarm device 10 and the fire alarm notification test of the emergency earthquake warning device 25 at a time.

  The implementation of the test by the test switch is not limited to such a form. When the test switch is operated, the device event signal indicating the fire alarm test is transmitted to the home alarm device 10 to perform the fire alarm test, and the earthquake early warning is issued. The device 25 itself may perform a fire alarm notification test, or the device 25 may transmit a device event signal indicating an emergency earthquake warning test to the dwelling alarm device 10 to perform an emergency earthquake warning device test. You may make it perform the test alert | report of an earthquake early warning. At these times, a response event signal is returned from the home alarm device that has received the device event signal transmitted from the earthquake early warning device, and after receiving this, the test notification from the earthquake early warning device 25 itself is performed. Anyway. In this way, a two-way communication test is simultaneously performed between the emergency earthquake warning device 25 and the residential alarm 10, and a more reliable operation guarantee can be performed.

  Of course, the fire test and the earthquake early warning test may be selected and performed by pressing the test switch. A test switch for instructing a fire test and a test switch for instructing an earthquake early warning test may be provided separately.

  When the earthquake early warning device 25 is installed in the same place as any of the residential alarms 10, emergency earthquake early warnings are output from both voices, making it difficult to hear. Therefore, in the present embodiment, the prohibition mode for prohibiting the output of the earthquake early warning can be set on the home alarm device 10 by using a dip switch or the like, and the same place as the emergency earthquake early warning device 25 (the place where the alarm and notification ranges overlap) The prohibition mode is set for the resident alarm installed in) so that even if an event signal indicating an emergency earthquake warning is received from the emergency earthquake warning device 25, information indicating the emergency earthquake warning is not output. To do.

  The prohibit mode setting function can be used in the same way even when a plurality of residential alarms are installed in the same place.

  As described above, the prohibit mode setting function may be provided on the side of the house alarm, but in general, it is assumed that the number of units installed in the house alarm is larger than that in the earthquake early warning device. In consideration of the overall cost, etc., the earthquake early warning device 25 may be provided. In this way, it is not necessary to install a prohibit mode setting function on a large number of installed security guards, and the overall cost of the system equipment can be suppressed. It is effective to prevent the operation from becoming complicated.

  In addition, if you want to take into account the overlap notification between the earthquake early warning device and the home alarm and the overlap notification between the home warning devices, install the prohibit mode setting function on both the home warning device and the earthquake early warning device. You may enable it to set each according to a situation etc. Naturally, at this time, when a plurality of earthquake early warning devices are installed at the same place, it is possible to set so as to avoid the redundant notification between the earthquake early warning devices.

  Of course, even in an installation situation in which alarms and notification sounds are output in duplicate, it is not always necessary to use the prohibit mode setting, and it is appropriately selected and set by the user's judgment.

  FIG. 2 is an explanatory view showing the appearance of a wireless residential security device according to the present invention. FIG. 2 (A) shows a front view and FIG. 2 (B) shows a side view.

  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 plurality of smoke inlets are opened in the center of the cover 12, and a smoke detector 16 is disposed inside the cover 12, so that a fire is detected when smoke from the fire reaches a predetermined concentration.

  Inside the plurality of openings provided in the cover 12, a smoke detector 16 is provided, and an acoustic hole 18 is provided on the lower left side of the smoke detector 16. A buzzer and a speaker are incorporated behind this, and an alarm sound and sound are provided. A message can be output. An alarm stop switch 20 is provided below the smoke detector 16.

  The alarm stop switch 20 also functions as an inspection switch that instructs self-inspection of the function of the home alarm device 10. For example, when the alarm stop switch 20 is operated during a fire alarm, the alarm is stopped, and when the alarm stop switch 20 is operated in a normal state, a function check is performed and the result is notified.

  The alarm stop switch 20 includes a switch cover formed of a translucent member and a tact switch (not shown) arranged inside the switch cover. In the vicinity of the tact switch inside the switch cover, an LED 22 for displaying an alarm is arranged as indicated by a dotted line. When the LED 22 is turned on, blinks, or blinks, the operation light passes through the switch cover portion of the alarm stop switch 20. Thus, the operating state of the LED 22 can be seen from the outside.

  In addition, a mounting hook 15 having an insertion hole in a substantially central portion 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 of a room to be installed and hooked through the insertion hole of the mounting hook 15, The housing alarm 10 can be fixedly installed on the wall surface in a so-called wall-hanging manner.

  In the residential alarm 10 of FIG. 1, a smoke detector 16 is provided as an example, and a residential alarm that detects smoke due to fire is taken as an example. However, the temperature of a thermistor or the like that detects heat due to fire is also taken as an example. House alarm with detection elements, house alarm to detect other physical phenomena associated with fire, alarm to detect gas leaks in addition to fire, various alarms to detect intruders, earthquakes and other abnormalities A warning device and a combination of these alarm devices are also included in the subject of the present invention. The alarm system of the present invention may be configured by mixing these various alarm devices.

  FIG. 3 is a block diagram showing an embodiment of the emergency seismic broadcast receiver and dwelling device provided in the alarm system of FIG. 1, and the dwelling device is shown for the dwelling device 10-1 installed in the living room. The other residence alarm devices 10-2 to 10-6 have the same configuration.

  The home guard 10-1 includes a processor 28 known as a one-chip CPU. For the processor 28, a wireless communication unit 30 including an antenna 31, a recording circuit unit (memory) 32, a sensor unit 34, and a notification unit 36. An operation unit 38 and a battery power source 40 are provided.

  The wireless communication unit 30 is provided with a transmission circuit 42 and a reception circuit 44 so that event signals can be transmitted and received wirelessly between the other residential alarm devices 10-2 to 10-6. The device event signal can be received. As the wireless communication unit 30, in Japan, for example, STD-30 (wireless equipment standard of a low power security system wireless station) or STD-T67 known as a standard of a specific low power wireless station of 400 MHz band. It has a configuration that conforms to the standard for specific low-power radio station telemeters, telecontrol and data transmission radio equipment.

  Of course, the wireless communication unit 30 has contents conforming to the standard of the assigned wireless station in the area in places other than Japan.

  In the memory 32 as a storage unit, a serial number 48 that is a serial number indicating the order of event signals, a transmission source code 50 that becomes an ID (own identifier) for identifying each home alarm, and a residence as shown in FIG. The group code | symbol 52 for comprising the interlocking | linkage group which performs an interlocking | linkage alarm with the installed residence guards 10-1 to 10-6 is stored.

  The serial number 48 is used for managing event signal relay processing and the like between alarm devices, particularly in wireless communication, but is not directly related to the present invention, and therefore will not be described in detail.

  As the transmission source code 50, for example, a 26-bit code code is used, and the serial number of the residential alarm is used so that it does not overlap with any of the residential alarms provided in the country.

  The group code 52 is a code that is set in common to a plurality of house alarms constituting the interlocking group, and the group code included in the event signal from another house alarm received by the wireless communication unit 30 is registered in the memory 32. Because this event signal is processed as a valid signal when it matches the group code 52, the alarm device belonging to another group that is installed in a neighboring house and does not require linkage is unnecessary. Can be avoided.

  The group code 52 does not necessarily have to be the same code for each house alarm, and by performing calculations based on this, it can be determined whether the group to which the self belongs and the group to which another house alarm belongs are the same. Anything is fine.

  The sensor unit 34 is provided with a smoke detector 16 that detects smoke and outputs a signal. As described above, the sensor unit 34 may be provided with a temperature detecting element such as a thermistor for detecting a temperature due to a fire, and various elements for detecting other physical phenomenon changes due to a fire, instead of the smoke detecting unit 16. .

  The notification unit 36 is provided with a speaker 56 that outputs an alarm sound and the LED 22 that displays an alarm. The speaker 56 outputs various voice messages, alarm sounds, and the like held by itself from a voice synthesis circuit unit (not shown) via an amplification unit (not shown). The LED 22 displays an abnormality such as a fire by blinking, blinking, or lighting. Instead of the speaker 56, a buzzer or the like may be used. Further, instead of the LED 22, a two-color LED, a liquid crystal display, or the like may be provided. Of course, an LED and a liquid crystal display may be provided together.

  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 an alarm sound of a fire or failure is output from the notification unit 36 by the speaker 56 or when an alarm display is performed by the LED 22. For example, if the alarm stop switch 20 is operated during the 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 display stops or stops 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 speaker 56 of the notification unit 36.

  When the alarm stop switch 20 is operated during the fault alarm, the fault alarm stop process may be performed after performing a predetermined self-inspection operation and informing the result. In this way, for example, the failure alarm stop process is performed after rechecking the sensor failure or the like, so that the user can be more clearly aware of the failure state. If the failure state has been resolved at this time, for example, a message such as “The failure has been resolved” may be output and the process may proceed to the failure stop process.

  Further, the operation unit 38 is provided with a mode switch 21. The mode switch 21 is a dip switch or the like provided on the back surface of the main body, and can set the emergency earthquake early warning prohibition mode on or off. When the prohibit mode is set (turned on) by turning on the mode switch 21, even if a device event signal indicating an emergency earthquake warning is received from the earthquake early warning device 25, information output indicating an emergency earthquake warning from the notification unit 36 is performed. Absent.

  Necessary when using this function, for example, when a house alarm is installed in a room where an earthquake early warning device is installed, or when a plurality of house alarms are installed in the same room. Because information can be output only to a predetermined device in the room according to the situation, it is possible to avoid redundant information output by a plurality of devices. The effect that it can be obtained.

  The battery power source 40 uses, for example, a lithium battery or an alkaline battery having a predetermined number of cells, and has a battery capacity of, for example, 10 by reducing the power consumption of the entire circuit unit including the wireless communication unit 30 in the residential alarm 10-1. The battery life of the year is guaranteed.

  The processor 28 is provided with functions of an event detection unit 58, a transmission processing unit 60, a reception processing unit 62, an alarm processing unit 64, and an emergency earthquake warning processing unit 66 as functions realized by executing the program.

  The event detection unit 58 detects events such as an abnormality (here, fire) detection by the sensor unit 34, an alarm stop by the operation unit 38, and an abnormality recovery in which the abnormality detection of the sensor unit 34 disappears. In addition, the event detection unit 58 receives the event contents obtained as a result of decoding the event signals from the other home alarm devices 10-2 to 10-6 and the device event signal from the emergency earthquake warning device 25 via the reception processing unit 62. To detect.

  The transmission processing unit 60 indicates a detection event when the event detection unit 58 detects its own event such as abnormality detection by the sensor unit 34, alarm stop by the operation unit 38, or abnormality recovery in which the abnormality detection of the sensor unit 34 disappears. The event signal is transmitted from the wireless communication unit 30 to the linked home policing device or emergency earthquake warning device. The reception processing unit 62 receives and decodes the event signal from the other residential alarm devices 10-2 to 10-6 and the device event signal from the emergency earthquake warning device 25 via the wireless communication unit 30.

  In addition, as a kind of apparatus event signal, the case where the fire alarm etc. of the residential alarm 10 is stopped by operation of the operation part 78 (after-mentioned) provided in the earthquake early warning apparatus 25 or the signal which shows an emergency earthquake early warning There are a signal indicating an alarm stop, a signal indicating an earthquake early warning test by operating a test switch 88 (described later) provided in the operation unit 78 of the earthquake early warning device 25, and the like.

  In addition, when the home alarm device 10 that has received the device event signal indicating the alarm stop transmitted from the wireless communication unit 80 (described later) of the earthquake early warning device 25 by the operation of the test switch 88 is itself the interlock source, The alarm may be continued, and the alarm may be stopped when it is the interlocking destination.

  The alarm processing unit 64 outputs an alarm sound indicating the interlocking source from the speaker 56 when the event detecting unit 58 detects a fire as its own abnormality, and drives the LED 22 to display an alarm indicating the interlocking source. Then, an event signal indicating a fire is transmitted to the other home police 10-2 to 10-6 and the earthquake early warning device 25.

  More specifically, the alarm processing unit 64 detects the link source from the speaker 56 of the notification unit 36 when the event detection unit 58 detects a fire based on the smoke detection signal of the smoke detection unit 16 provided in the sensor unit 34. An alarm sound indicating, for example, “Woo Woo is a fire” is repeatedly output, the LED 22 is turned on to display an alarm indicating the interlocking source, and an event signal indicating a fire is transmitted via the transmission processing unit 64 and the transmission circuit 42. The transmission circuit 42 of the wireless communication unit 30 transmits the signal from the antenna 31 to the other residential alarm devices 10-2 to 10-6 and the emergency earthquake warning device 25.

  Further, the alarm processing unit 64 receives an event signal indicating a fire from any of the other residential alarm devices 10-2 to 10-6 by the reception circuit 44 of the wireless communication unit 30, and becomes effective in the reception processing unit 62. Sometimes, the alarm sound indicating the link destination is repeatedly output from the speaker 56 of the notification unit 36, for example, “Woo-woo, check that another fire alarm has been activated”, and the LED 22 blinks simultaneously. A warning display is displayed. When the earthquake early warning device 25 receives an event signal indicating a fire from the home alarm device 10-1, the emergency earthquake early warning device 25 confirms from the speaker 74 (described later), for example, “Woo Woo fire alarm has been activated. Please output "voice message.

  Here, the event detection unit 58 detects a sensor failure and a low battery failure. The sensor failure is detected by reading the smoke detection signal output from the smoke detector 16 of the sensor 34 at a predetermined measurement time interval T1, for example, T1 = 1 second by A / D conversion, and holding it in the buffer area of the memory 32. For example, at every predetermined time interval T2 = 10 minutes, an average value of 10 minutes of detection data held in the buffer area of the memory 32 is obtained, and this average value is used as a predetermined reference level (referred to as a zero point level). When the output is lower, it is determined that the sensor unit 34 has a fault, for example, because the output is stopped.

  The reason why the 10-minute average value of the smoke concentration detection signal falls below the zero point level in this way may be that a failure such as disconnection of the light receiving element provided in the smoke detector 16 or stop of the light receiving amplifier has occurred. Is expensive. Even when a temperature detection element such as a thermistor is provided in the sensor unit 16, a sensor failure can be similarly detected by various processes.

  Low battery failure is detected by reading the power supply voltage of the battery power supply 40 by A / D conversion at a predetermined measurement time interval T3, for example, T3 = 4 time intervals, and comparing it with a predetermined threshold voltage. The battery failure is determined, and the low battery failure is determined when the determination of the low battery failure continues for a predetermined number of times.

  When the event detection unit 58 detects a sensor failure or a low battery failure, the alarm processing unit 64 outputs a sensor failure or a low battery failure alarm indicating an interlocking source by an alarm sound from the speaker 56 of the notification unit 36 and the display of the LED 22. Let Further, the alarm processing unit 64 transmits an event signal indicating a sensor failure or a low battery failure to the other home alarm devices 10-2 to 10-6 and the emergency earthquake warning device 25 to send the home alarm devices 10-2 to 10-6. In addition, the emergency earthquake warning device 25 is caused to issue a sensor failure or low battery failure alarm indicating the interlocking destination with an alarm sound and / or display.

  Further, when the alarm processing unit 64 receives an event signal indicating a sensor failure or a low battery failure from any of the other home alarm devices 10-2 to 10-6 via the reception circuit 44 and the reception processing unit 62, the alarm processing unit 64 notifies the user. An alarm sound from the speaker 56 of the unit 36 and a display of the LED 22 are output to output a sensor failure or a low battery failure alarm indicating the link destination.

  When the event detection unit 58 detects a sensor failure, the alarm processing unit 64 continuously outputs, for example, “it is a pin failure” multiple times as a sensor failure alarm sound indicating the link source (failure source) from the speaker 56 of the notification unit 36. At the same time, for example, the LED 22 is turned on, and thereafter, a process of outputting a voice “pick failure” and displaying the LED 22 a plurality of times is repeated at regular intervals.

  Also, the alarm processing unit 64 transmits an event signal indicating a sensor failure to the other residential alarm devices 10-2 to 10-6 and the earthquake early warning device 25 via the transmission processing unit 60 and the transmission circuit 42, thereby interlocking. A sensor failure alarm indicating the destination is output. At this time, for example, “beep alarm device is faulty” or “beep alarm device is faulty” is output as an alarm sound, and a flashing display different from that of the interlock source is performed.

  If the event signal includes an identification code (ID) that identifies the home alarm device, the emergency earthquake warning device 25 decodes the event signal to determine which of the home alarm devices 10 has failed. It can be displayed. This also applies to the low battery failure described below. Although the interlocking home alarm system does not have a dedicated receiver, the earthquake early warning device 25 can be used as a device acting as a fire receiver in a so-called fire alarm facility. It becomes possible to collectively manage the monitoring network of the home alarm.

  Further, when the event detection unit 58 detects a low battery failure, the alarm processing unit 64 outputs, for example, “Battery is dead” from the speaker 56 of the notification unit 36 as a low battery failure alarm sound indicating the link source (failure source). For example, the LED 22 is turned on continuously for a plurality of times and, after that, the process of outputting a sound “battery exhausted” and displaying the LED 22 a plurality of times is repeated at regular intervals.

  Also, the alarm processing unit 64 transmits an event signal indicating a low battery failure to the other mortgage alarm devices 10-2 to 10-6 and the emergency earthquake warning device 25, thereby generating a low battery failure alarm indicating the interlock destination. "Pip alarm is out of battery" or "Pi alarm is out of battery" is output as well as a blinking display different from the interlock source.

  Further, the alarm processing unit 64 detects the operation of the alarm stop switch 20 during the output of the fire alarm sound indicating the interlocking source or the fire alarm sound indicating the interlocking destination, or the other residential alarm devices 10-2 to 10-6. When any event signal or device event signal reception indicating an alarm stop is detected from any of the earthquake early warning devices 25, the output of the fire alarm by the voice message from the speaker 56 and the alarm display of the LED 22 is stopped. At this time, the alarm display by the LED 22 may be stopped after continuing for a predetermined time. In addition, during the fire alarm indicating the interlock source, at least the output of the alarm sound may be continued even if an event signal indicating the alarm stop or the device event signal is received.

  Furthermore, when the alarm processing unit 64 detects an alarm stop operation of the alarm stop switch 20 provided in the operation unit 38 during the output of the sensor failure indicating the interlocking source or the low battery failure alarm, the alarm processing unit 64 generates an alarm sound indicating its own interlocking source. Stop and stop the fault display for a predetermined time, and then stop and stop the alarm signal output to the other alarm devices 10-2 to 10-6 and the earthquake early warning device 25 that are outputting the fault alarm indicating the link destination. Is transmitted to stop the alarm warning sound and the fault display of the home alarm devices 10-2 to 10-6 and the earthquake early warning device 25.

  When the earthquake early warning processing unit 66 receives a device event signal indicating an emergency earthquake early warning from the emergency earthquake early warning device 25 via the receiving circuit 44 and the reception processing unit 62, the emergency earthquake early warning processing unit 66 outputs a voice message as information indicating the emergency earthquake early warning. The information is output from the speaker 56 of the notification unit 36 and the LED 22 is turned on, blinks, or blinks.

  Further, when receiving the device event signal indicating the emergency earthquake warning test from the emergency earthquake warning device 25, the emergency earthquake warning processing unit 66 outputs a voice message indicating the emergency earthquake warning test from the speaker 56 of the notification unit 36. The LED 22 is turned on, blinks, or blinks.

  Further, the emergency earthquake bulletin processing unit 66 receives the emergency earthquake bulletin from the emergency earthquake bulletin device 25 when the prohibit mode in which the output of the information indicating the emergency earthquake bulletin is prohibited by the setting ON operation of the mode switch 21 is set. Even if the device event signal shown is received, the voice message of the information indicating the earthquake early warning test is not output.

  Prohibition of voice message output by the mode switch 21 may be set for emergency earthquake warnings.

  When the prohibit mode setting switch is provided in the operation unit 78 of the earthquake early warning device 25 described later, the fire alarm output from the earthquake early warning device 25 may be prohibited by setting the prohibit mode switch.

  Even when voice messages and sound output are prohibited, only display may be performed, and conversely, only display may be prohibited. Further, this may be specified separately. That is, the setting of output prohibition can be appropriately selected and set for the earthquake early warning, the earthquake early warning test, and the sound output and display output.

  In this way, the notification method can be selectively set according to the type of event for which notification output is performed, and an appropriate notification pattern can be obtained depending on the user's wishes and the installation status of the device. Easy to use.

  Next, the earthquake early warning device 25 will be described. The earthquake early warning device 25 includes a processor 68, an FM receiving unit 70 including an antenna 71, a sound amplifying unit 72, a speaker 74, a display unit 76, an operation unit 78, and a wireless communication unit 80. An emergency earthquake warning analysis unit 90, a device event detection unit 92, a transmission control unit 94, a reception control unit 96, and an alarm control unit 98 are provided as functions realized by execution.

  The FM receiver 70 tunes the tuner to the FM station selected by the operation of the operation unit 78, receives FM broadcast radio waves via the FM antenna 71, demodulates and outputs as an audio signal. The sound amplifying unit 72 stops operating in the standby state, and therefore, the FM broadcast received from the speaker 74 is not reproduced and output. When the earthquake early warning signal is detected by the analysis processing of the processor 68, the voice amplifying unit 72 is switched to the operation state. At that time, the broadcast content of the emergency earthquake early warning reproduced and output from the FM receiving unit 70 is transmitted via the amplifying unit 72. And output from the speaker 74. The display unit 76 displays necessary for FM broadcast reception such as reception standby display, emergency earthquake warning reception display, channel selection frequency display, and fire alarm display.

  The wireless communication unit 80 is provided with a transmission circuit 84 and a reception circuit 86 so that a device event signal can be wirelessly transmitted from the antenna 82 to the home guard 10. The radio communication unit 80 conforms to STD-30 or STD-T67, which is known as a standard for a specific low-power radio station in the 400 MHz band, for example, in the case of Japan, as in the case of the residential alarm 10-1. It has a configuration.

  Note that, in the memory (not shown), as in the memory 32 of the resident alarm 10-1, a serial number that is a serial number indicating the order of event signals and a transmission that is an ID (identifier) that identifies the earthquake early warning device is provided. An original code and a group code for constituting an interlocking group are stored.

  The device event detection unit 92 provided in the processor 68 detects the reception of the emergency earthquake warning signal based on the analysis processing result of the two chime sounds that flow at the beginning of the emergency earthquake warning by the earthquake early warning analysis unit 90. The alarm control unit 98 operates the audio amplifying unit 72 for a predetermined time to cause the speaker 74 to reproduce and output the emergency earthquake warning. The analysis of the chime sound of the emergency earthquake warning by the emergency earthquake warning analysis unit 90 is performed by, for example, the vector correlation method described in Patent Document 3.

  The device event detection unit 92 detects device events such as the reception of an earthquake early warning signal by the earthquake early warning analysis unit 90 and the reception of an event signal from the home alarm device 10 by the reception control unit 96. When the device event detection unit 92 detects the reception of the earthquake early warning signal, the transmission control unit 94 transmits a device event signal indicating the emergency earthquake early warning to the Dwelling Guard 10 side, and outputs information indicating the emergency earthquake early warning. . The reception control unit 96 receives an event signal from the home alarm device 10 via the reception circuit 86.

  The alarm processing unit 98 operates the audio amplifying unit 72 to output an alarm sound from the speaker 74 when the apparatus event detection unit 92 detects reception of an event signal indicating a fire from any of the residential alarms 10. At the same time, the display unit 76 displays a fire. Moreover, the alarm process part 98 stops an alarm sound and a fire display, when the apparatus event detection part 92 receives the event signal which shows the fire recovery or alarm stop from any of the dwelling alarm devices 10. FIG.

  The operation unit 78 is provided with a test switch 88. When the test switch 88 is operated, the operation of the test switch 88 is detected by the device event detection unit 92, and based on this, the transmission control unit 94 transmits a device event signal indicating an emergency earthquake warning test to the Dwelling Guard 10 side to perform the test. The notification operation is performed.

  Further, the alarm control unit 98 may cause the speaker 74 and the display unit 76 to perform an alarm sound indicating a fire and display test notification based on the operation detection of the test switch 88 by the device event detection unit 92.

  In addition, a mode switch for setting prohibition of fire alarm is provided in the operation unit 78, and when the earthquake early warning device 25 is installed at the same place as the alarm device, or when the alarm alarm linked notification is not required, the mode switch You may make it prohibit fire alarm notification by operation.

  The power source of the earthquake early warning device 25 may be a commercial AC power source or a battery. Furthermore, another dedicated power source may be used.

  FIG. 4 is an explanatory diagram showing the format of the event signal and device event signal used for the interlocking alarm in this embodiment. In FIG. 4, the event signal 46 includes a serial number 48, a transmission source code 50, a group code 52, and an event code 54.

  The serial number 48 is a serial number indicating the order of event signals, and is incremented by one each time an event signal is transmitted. The serial number 48 is generated asynchronously by each of the residential alarm 10 and the earthquake early warning device 25. The serial number 48 is used for managing event signal relay processing, etc., mainly in wireless communication between the home alarm device 10 and the earthquake early warning device 25, but is not directly related to the present invention, so that it will be described in detail. Is omitted.

  The transmission source code 50 is, for example, a 26-bit code, and uses the serial number of the home alarm device 10 and the earthquake early warning device 25 or the like. The group code 52 is, for example, an 8-bit code, and the same group code is set for, for example, the residential alarm devices 10-1 to 10-6 and the emergency earthquake warning device 25 of FIG.

  As the group code 52, in addition to setting the same group code for the same group of house alarms, for example, a reference code common to the house alarms constituting a predetermined group, and a transmission unique to each house alarm A different group code may be used for each mortgage obtained from the calculation with the original code.

The event code 54 is a code representing the event content such as a fire, gas leak (for example, a gas leak alarm device or a residence alarm device having a gas leak detection function), and in this embodiment, a 4-bit code is used. For example, 0001 = fire 0010 = gas leakage 0011 = alarm stop 0100 = recovery 0101 = sensor fault 0110 = low battery fault 0111 = emergency earthquake warning 1000 = emergency earthquake warning test. Here, 0000 is used for periodic notification, for example, without event detection.

  By increasing the number of bits of the event code 42 to 5 bits and 6 bits, more event contents can be expressed. For example, recovery event codes may be divided into fire recovery and failure recovery. In an alarm device that detects an abnormality other than a fire, the above-described 0001 may be replaced with an abnormal event to be detected, and the type of abnormal event to be detected may be added to the above, for example. In this way, for example, alarm devices having different types of abnormalities to be detected can be mixed in the same group.

  5 and 6 are flowcharts showing an example of the monitoring process in the residential alarm 10-1 of FIG. It becomes the same process also about the other residence alarm devices 10-2 to 10-6. In FIG. 5, when the power supply by the battery power source 40 of the mortgage alarm device 10-1 is started, various settings including initialization, self-diagnosis, and prohibition mode setting are read in step S1. If not, the process proceeds to step S2 to monitor the fire. When the smoke detection signal output from the sensor unit 34 exceeds a predetermined fire level, a fire is determined in step S2, and the process proceeds to step S3, where an event signal including a serial number, a transmission source code, a group code, and an event code indicating a fire Is wirelessly transmitted to the other home alarm devices and the earthquake early warning device 25, and in step S4, the interlock source is indicated by the alarm sound such as a voice message or buzzer sound from the speaker 56 of the notification unit 36 and the alarm display by lighting the LED 22. Outputs a fire alarm.

  Subsequently, in step S5, it is determined whether or not there is a fire recovery in which the smoke detection signal from the sensor unit 34 is reduced and the fire state is resolved. When a fire recovery is determined, a serial number, a transmission source code, and a group code are determined in step S6. After transmitting the event signal including the event code indicating the fire recovery to the other housing alarm and the earthquake early warning device 25, the source of the interlocking by the alarm sound from the speaker 56 and the alarm display by turning on the LED 22 is shown in step S7. Stop the fire alarm. The alarm display by the LED 22 may be turned off after a predetermined time has elapsed.

  Subsequently, in step S8, it is determined whether or not the alarm stop switch 20 is operated. If switch operation is determined, it is determined in step S9 whether or not an alarm is being issued. If it is determined in step S9 that an alarm is being issued, the process proceeds to step S10, and an event signal including a serial number, a transmission source code, a group code, and an event code indicating an alarm stop is transmitted to the other residential alarm and the earthquake early warning device 25. In step S11, the alarm sound output indicating the interlock source from the speaker 56 is stopped, and the alarm display by turning on the LED 22 is turned off. The LED 22 may be turned off after a predetermined time has elapsed.

  When it is determined in step S9 that the alarm is not in progress, a predetermined inspection operation is performed to notify the result, but the illustration is omitted.

  Then, it progresses to step S12 of FIG. 6, and the presence or absence of reception of the event signal which shows the fire from another residence guard is discriminate | determined. When it is determined that an event signal indicating a fire from another house alarm is detected, the process proceeds to step S13, where an alarm sound is output from the speaker 56 as a fire alarm indicating the interlocking destination, and an alarm display by blinking of the LED 22 is performed.

  Next, in step S14, it is determined whether or not an event signal indicating a fire recovery from another house alarm is received, and when an event signal indicating a fire recovery is received, the process proceeds to step S15 and is performed as an interlock destination alarm. The alarm display by the alarm sound output from the speaker 56 and the blinking of the LED 22 is stopped.

  Next, in step S16, it is checked whether or not an event signal indicating an alarm stop from another house alarm or a device event signal indicating an alarm stop from the earthquake early warning device 25 is received, and an event signal or device indicating an alarm stop is checked. If it is determined that the event signal has been received, the process proceeds to step S17 to determine whether or not an alarm is present. If it is determined that the alarm is being performed, the process proceeds to step S18 to stop the alarm sound output as the interlocking destination and stop the alarm display.

  Subsequently, in step S19, it is determined whether or not an emergency earthquake warning prohibition mode is set. If no prohibition mode is set, the process proceeds to step S20 to check whether or not an event signal indicating an emergency earthquake warning is received. When it is determined that the device event signal indicating the earthquake early warning from 25 is received, an emergency earthquake warning message is output from the speaker 56 of the notification unit 36 in step S21, and the LED 22 is turned on at the same time, for example.

  If it is determined in step S19 that the emergency earthquake warning prohibition mode is set, steps S20 and S21 are skipped, and no emergency earthquake notification message is output even if reception of a device event signal indicating the emergency earthquake warning is determined. This is a case where the residential alarm 10-1 is installed in the same room as the emergency earthquake warning device 25 as shown in FIG. Step S19 and step S20 may be switched in order.

  Subsequently, the process proceeds to step S22, where it is checked whether or not an event signal indicating an emergency earthquake warning test has been received. When it is determined that an event signal indicating an emergency earthquake warning test has been received, an emergency earthquake warning test message is notified in step S23. It outputs from the speaker 56 of the part 36, and LED22 is lighted simultaneously, for example. The above processing is repeated until an operation stop instruction due to power-off is determined.

  In the flowcharts of FIGS. 5 and 6, the emergency earthquake bulletin or the emergency earthquake bulletin test stop processing by operating the test switch 88 provided in the operation unit 78 of the earthquake early warning device 25 is omitted. During the notification of the breaking news or the earthquake early warning test, it is possible to determine whether or not the device event signal indicating the notification stop is received, and to stop the notification when the device event signal is received.

  In addition, it is determined whether or not the alarm stop switch 20 is operated during the notification of the earthquake early warning or the earthquake early warning test, and when there is an operation, the alarm is stopped (or the alarm is stopped) to other housing alarms or the earthquake early warning device. An event signal indicating the above can be transmitted to stop notification by another alarm device or the earthquake early warning device.

  FIG. 7 is a flowchart showing a processing example of the earthquake early warning device 25 shown in FIG. In FIG. 7, when the earthquake early warning device 25 is turned on, initialization and self-diagnosis are performed in step S31. If there is no error, the process proceeds to step S32 to perform FM station tuning processing by the tuning operation of the operation unit 78. .

  Subsequently, the process proceeds to a reception standby operation in step S33. In the reception standby operation, the FM receiving unit 70 is operated to receive and reproduce FM broadcast radio waves, but the operation of the audio amplifying unit 72 is stopped and broadcasting from the speaker 74 is not performed.

  Subsequently, in step S34, the presence / absence of the chime sound of the emergency earthquake warning is determined through the analysis process of the emergency earthquake warning analysis unit 90. When the chime sound reception is determined, the process proceeds to step S35, and the voice amplifying unit 72 is operated. The emergency earthquake bulletin broadcast received at that time is output from the speaker 74 at a sufficiently large volume.

  Next, the transmission circuit 84 of the radio | wireless communication part 80 is operate | moved by step S36, and the apparatus event signal which shows an emergency earthquake early warning is output to the dwelling guard 10. FIG. Subsequently, in step 37, after the elapse of a predetermined time, the process proceeds to step S38, and the operation of the audio amplifying unit 72 is stopped to stop the output of the broadcast sound.

  In addition, when the notification stop instruction | indication by the operation part 78 is detected during the emergency earthquake early warning broadcast sound output from the speaker 74, emergency earthquake early warning broadcast sound output is interrupted (illustration omitted).

  Then, it progresses to step S39 and it is discriminate | determined the presence or absence of the event signal which shows the fire from any of the residence guards 10. FIG. When it is determined in step S39 that an event signal indicating a fire from any of the residential alarms 10 has been determined, the process proceeds to step S40, and a fire alarm is output by an alarm sound and an alarm display by the speaker 74 and the display unit 76.

  Next, in step S41, together with the presence or absence of an alarm stop instruction by operation of the operation unit 78, the presence or absence of an event signal indicating a fire recovery or an event signal indicating an alarm stop is checked from any of the residential alarms 10; If it is determined whether an operation instruction or event signal reception indicating a fire recovery or event signal reception indicating an alarm stop is determined, the process proceeds to step S42 to determine whether or not an alarm is present. Stop display. When the alarm is stopped based on the operation instruction of the operation unit 78, a device event signal indicating the alarm stop is output from the transmission circuit of the wireless communication unit 80 to the home alarm device 10 (not shown). The above processing is repeated until an operation stop instruction due to power-off is determined in step S44.

  In addition, although said embodiment took the example of the residence alarm device which detects and alarms a fire, the alarm system which has arrange | positioned the gas leak alarm device, CO alarm device, various crime prevention alarm devices, and those various The present invention can be similarly applied to an alarm system in which the alarm devices are mixed.

  In addition, as another embodiment of the earthquake early warning device, the emergency earthquake early warning device has a function of a resident alarm, the emergency earthquake early warning device detects an abnormality such as a fire and alarms as a link source and other resident alarms It is also possible to send an event signal to alarm as an interlocking destination.

  Also, the alarm devices do not necessarily have to be linked to each other, and any alarm device can be used as long as the predetermined alarm device can be linked with the emergency earthquake warning device. Some alarm devices may be linked and other alarm devices may not be linked. Furthermore, it does not prevent that there is one alarm device. On the other hand, a plurality of earthquake early warning devices may be provided. At this time, the earthquake early warning devices may be linked to each other.

  Further, each link between the alarm device and the earthquake early warning device does not have to be based on wireless communication, may be wired communication, or may be a combination of wired and wireless as appropriate.

  In addition, the operation means shown as the alarm stop switch 20 and the test switch 88 in the above embodiment do not necessarily need to be switches, and instruct the alarm history output by external communication using a remote control device or the like. Any means or method may be applied. The same applies to the dip switch for prohibition mode setting and other switches provided in the operation unit 78 of the earthquake early warning device 25.

  In addition, it is impossible to prohibit the alarm output function of a house alarm (house fire alarm) according to the standard, but when using an appropriate alarm device other than a house alarm, an alarm on the alarm side is issued. It is also possible to provide a mode setting function for prohibition. In this way, for example, instead of outputting an abnormal alarm from the earthquake early warning device 25 (corresponding to a fire in the case of a residential alarm), an abnormal alarm from an alarm device installed in the vicinity of the emergency earthquake early warning device 25 is output. You can also take a pattern that prohibits

  Moreover, the interlocking output of the abnormality alarm (fire alarm etc.) from the resident alarm to the earthquake early warning device may be performed only by display. For example, a sound alarm output such as a buzzer sound or a voice message is sufficient with only a residential alarm, but if you want to enhance the visual notification effect of the occurrence of abnormality using a flashlight with high power consumption, etc. A display device such as a flashlight is installed in the emergency earthquake warning device that has a relatively low need to reduce power consumption by using a dedicated power source, etc., and linked to an abnormal (fire) alarm of a residential alarm The effect of the display notification may be enhanced by operating.

  In addition, the flowcharts in the above-described embodiments have described a schematic example of processing, and the order of processing is not limited to this. Further, it is possible to provide a delay time between each process or between processes, insert another determination, or the like.

  In addition, the processor of each device described in the above embodiment can replace some or all of its functions with other means such as wired logic. Other electrical and functional configurations including the processor can be appropriately integrated and abolished.

  Further, the earthquake early warning device may directly receive the FM early earthquake warning as in the above embodiment, or may indirectly receive it through another device or facility.

  In addition, “reception is received”, “no reception”, “when received”, “determination of reception”, etc., as described in the above embodiment, also determine whether the received signal is recognized as valid. Contains.

Further, depending on the standard of the alarm device, the display by the LED of the above embodiment may not be recognized as “alarm”, but in the present invention, the alarm display is performed regardless of whether it is included in the “alarm” according to the standard. It is described as a display accompanying an alarm or simply as a display. Any display means may be used as long as the object of the present invention can be achieved. The display unit may be provided separately from the alarm device.
