Abstract

PROBLEM TO BE SOLVED: To appropriately and promptly deal with the case where a fire occurs while failure alarm sound is outputted from a speaker during a checking operation.SOLUTION: In the case where a check instructing operation using an alarm stop switch 20 under a normal state is detected by an event detection section 58, on the basis of a low-battery failure flag 78 or a sensor failure flag 80 that is failure information stored in a memory 32, a check processing section 74 outputs failure alarm sound indicating a failure source from a speaker 56 of an alarm section 36. In the case where an event signal indicating an abnormality from another alarm is received effectively by the event detection section 58 while failure information is outputted by the check processing section 74, a failure alarm interruption section 76 interrupts the failure alarm sound from the speaker 56 and outputs fire alarm sound indicating an interlock destination.

Description

The present invention relates to an interlocking alarm device that outputs an alarm sound and outputs a warning sound by transmitting a signal indicating the occurrence of an abnormality to another alarm device when the occurrence of an abnormality such as a fire is detected.

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

  In such a house alarm, the sensor unit and the alarm unit are integrally provided in the house alarm, and when a fire is detected from the detection signal of the sensor unit, a fire alarm sound of a predetermined pattern is output from the alarm unit. It is easy to install and inexpensive because it can be used for fire monitoring and alarms without requiring a dedicated receiving facility, etc. Yes.

  In addition, by communicating between multiple home alarms, when a fire alarm sound is output from any home alarm, an interlocked home police that outputs a fire alarm sound in conjunction with other home alarms. A vessel system has also been proposed.

  In such an interlocked house alarm system, when a fire is detected by the house alarm, the interlocking house alarm that detects the fire has a predetermined pattern of fire alarm sound including a message and an alarm sound, for example, “Woo Woo On the other hand, for the alarm device that is linked, for example, a fire alarm sound that indicates the link destination is displayed, for example, “Please check if another fire alarm is activated. I am trying to output.

  In recent years, as a result of efforts to reduce the power consumption of residential alarms, a long battery life of, for example, 10 years or more is guaranteed, and no battery replacement is required during that period. When battery life (remaining capacity) decreases when battery life is approached after long-term use, a battery warning notice (hereinafter referred to as “low battery failure alarm”) is output to prompt battery replacement. ing.

  After the start of the output of the low battery failure alarm (after the battery voltage drop is detected), it is only necessary that the intermittent low battery alarm output can be continued for a predetermined time (for example, 72 hours) or longer. If the battery is replaced within the range, there is no problem. In general, the low battery alarm is not a highly urgent alarm like a fire alarm because it is designed to allow normal monitoring operation during this period.

  Therefore, as a low battery failure alarm, conventionally, in order to avoid the acoustic alarm output from nighttime to early morning, which is a sleeping time, as much as possible, a battery exhaustion alarm is output from the speaker after a predetermined time has elapsed after detecting a decrease in battery voltage. When a fire alarm (Patent Document 1) or the battery voltage has dropped below a predetermined voltage, a power lamp or the like is lit or blinked to notify the battery drop, and a switch operation is performed in this state. A battery-type alarm device (Patent Document 2) is known that outputs a voice message including content for prompting battery replacement from a speaker.

  If the battery voltage drop is detected while the user is absent for a long period of time, the low battery failure alarm will be output continuously for as long as possible with the minimum necessary power consumption. In addition, an alarm device has also been proposed in which a battery is surely noticed and a battery operation is known by a switch operation (Patent Document 3).

  In addition, in the case of the resident alarm of the interlocking type alarm system, in addition to the automatic inspection that periodically determines whether or not there is a low battery failure, there is a sensor failure such as sensor failure such as failure of sensor, detection circuit, voice notification circuit, contamination, etc. Automatic inspection is periodically performed. When inspection is instructed by operating the alarm stop switch in a normal state, the inspection result stored in the memory is notified.

  If there is no problem, the inspection result notification is a low volume sound compared to the actual failure warning sound, for example, the same warning sound as the fire warning sound, “Woo Woo fire alarm activated” To output once. This is because it is clear that the operator is in the vicinity of the alarm device at the time of inspection by manual operation, and the result can be sufficiently announced even at low volume, and other residents who are far away due to the high volume, etc. This is to avoid bothering.

On the other hand, if a low battery failure is detected, a failure alarm sound such as “Battery dead” is output multiple times, and if a sensor failure is detected, a failure alarm sound such as “pick failure” is output multiple times. To do.

  However, in such a conventional interlocked alarm system, the inspection is instructed by operating the alarm stop switch in a normal state, and another location is output during the output of a low battery failure or sensor failure failure alarm sound. In the unlikely event that a fire breaks out, the fault alarm sound is output even if the event signal indicating a fire is received effectively from another residential alarm because the fault alarm sound is being output to the residential alarm device that performed the inspection instruction operation. The fire alarm sound cannot be output until the output of is completed, and there is a possibility that the fire alarm sound from the resident alarm device that has instructed the inspection cannot be appropriately output.

  If there is no obstacle to the inspection instruction operation, the alarm sound for speaker inspection (acoustic output function confirmation) such as “Woo Woo fire alarm activated” should be used as the actual fire alarm sound. Output once at a lower volume, and then indicate the link destination based on the effective reception of an event signal indicating a fire from another house alarm, such as “Please confirm that another fire alarm has been activated” There is also a problem that it is difficult to distinguish whether the alarm sound is a warning sound due to an inspection instruction or a fire because a fire alarm sound is output.

SUMMARY OF THE INVENTION An object of the present invention is to provide an interlocking type alarm device that can appropriately and quickly cope with a fire when a failure alarm sound is output by an inspection instruction operation.

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 the monitoring process of the residential alarm following FIG. Flowchart showing the monitoring process of the residential alarm following FIG.

  FIG. 1 is an explanatory view showing an installation state of an alarm system using a house alarm according to the present invention for a house. In the example of FIG. 1, a wireless dwelling alarm (for dwelling) that detects and alerts to fire in each of the warning areas of the living room, kitchen, children's room, master bedroom, and staircase provided in the house 24. Fire alarms) 10-1 to 10-6 are installed.

  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 corresponding monitoring area in each part of the house. Here, six units monitor the fire of the entire house. Is going. If a fire has occurred in the kitchen of the house 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 interlock source, and an event signal (indicating a fire) is sent to the other home alarm devices 10-2 to 10-6 as the interlock destination. Hereinafter referred to as “fire event signal”). When other fire alarms 10-2 to 10-6 have effectively received the fire event signal from the interlocking home police 10-1, they perform an alarm operation as an interlocking destination by an alarm sound and an alarm display.

  Here, “effective reception” detects that this event signal has been received effectively when the group code included in the received event signal matches the group code registered in the memory. Moreover, the transmission source code | cord | chord is included in the event signal transmitted from the residence police device 10-1 to 10-6 as identification information which shows the residence police device of a transmission origin, for example. In addition, the residence police device 100 which received the event signal effectively performs relay transmission of the event signal as needed.

  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 resident alarms 10-2 to 10-6 that are linked to each other output a disaster warning sound by a voice message such as “Please confirm that another fire alarm has been activated”.

  Moreover, as an alarm display accompanying the alarm of the home police device 10-1 which became the interlocking | linkage origin, LED is lighted, for example. On the other hand, in the interlocking residence police 10-2 to 10-6, the LED is blinked. As a result, the alarm display by the LED in the interlock source alarm and the interlock destination alarm can be distinguished.

  The interlocking source LED may be blinking and the interlocking destination LED may be blinking, 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, a two-color LED capable of emitting both red and yellow by combining two LEDs can be adopted.

  When the alarm stop switch is operated in a state in which the house alarm devices 10-1 to 10-6 are emitting 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 10-1 which is the interlocking source, the alarms (alarm sound output and / or alarm display output) of all the home police devices 10-1 to 10-6. ), And when the alarm stop operation is performed in any of the home police 10-2 to 10-6 that are the interlocking destination, the alarm of the home police 10-1 that is the interlocking source does not stop, The alarms of the linked home alarm devices 10-2 to 10-6 are stopped. In addition, in the following description, when calling the housing alarms 10-1 to 10-6 without distinguishing them, they are referred to as the housing alarms 10.

  In addition, the house alarm 10 automatically executes a failure detection process for detecting a low battery failure from a decrease in the voltage supplied from the battery power as a built-in test in the background every predetermined period. When a low battery failure is detected, A low battery fault alarm indicating the linkage source (failure source) is output, and an event signal indicating a low battery fault (low battery fault event signal) is transmitted to other housing alarms to indicate a low level indicating the linkage destination (failure destination). Output a battery fault alarm.

  The low battery failure alarm indicating the link source outputs, for example, “Battery out of battery” continuously several times from the speaker of the Dwelling Unit 10 and turns on the LED, for example, and thereafter, the periodic notification timer “picks” every predetermined time. Repeats the process of outputting the sound “battery exhausted” and displaying the LED multiple times. In addition, the low battery failure alarm indicating the interlocking destination continuously outputs, for example, “a separate alarm device is out of battery” from the speaker of the home alarm device 10 a plurality of times and blinks the LED, for example.

  In addition, when the alarm stop switch that functions as a check switch in the normal state is operated, the home alarm device 10 detects a low battery failure by a failure detection process automatically executed as a built-in test. For example, “Battery out of battery” is output continuously several times and the LED is lit for example, and at the same time, an event signal indicating a low battery failure (low battery failure event signal) is sent to other home alarms, For example, a low battery failure alarm indicating “) is output continuously several times and another LED flashes, for example.

  On the other hand, when the low battery failure is not detected normally, the same content as the fire alarm sound to check the speaker operation “Please confirm that the Woo fire alarm has been activated” is used as a speaker check alarm sound at low volume Output once.

  In addition, the house alarm 10 automatically executes a failure detection process (automatic inspection) for determining a sensor failure in the background as a built-in test every predetermined cycle, and indicates a link source (failure source) when a sensor failure is detected. In addition to outputting a sensor failure alarm, an event signal indicating a sensor failure (sensor failure event signal) is transmitted to another residential alarm device to output a sensor failure alarm indicating a linkage destination (failure destination).

  The sensor failure determined by the home alarm device 10 includes a sensor, a detection circuit, the presence or absence of a voice notification circuit failure, a sensitivity abnormality due to contamination, and the like.

  In addition, when the alarm device operates the alarm stop switch that functions as an inspection switch in the normal state, the home alarm device 10 detects the sensor failure by the failure detection process automatically executed as a built-in test. For example, “Fail” is output continuously several times as a failure alarm sound indicating that the source is), and the LED is turned on, for example, and then a “beep failure” audio output and LED turn on every predetermined time by the periodic notification timer Repeat the display with multiple times.

  In addition, when the home alarm device 10 detects a sensor failure, it transmits an event signal indicating the sensor failure (hereinafter referred to as “sensor failure event signal”) to another home alarm device, for example, “a separate alarm device has failed. "Also" is output and a different display from the interlock source, for example, blinking.

  Further, when the alarm device 10 operates a warning stop switch that functions as a check switch in a normal state, when the sensor failure is determined by a failure detection process automatically executed as a built-in test, the residence warning device 10 may be, for example, “ “Pic battery is out” is output continuously several times and the LED is turned on, for example, and at the same time, a sensor failure event signal is sent to other home alarms. "Alarm is out of order" is output continuously several times and the LED blinks, for example.

  On the other hand, when the sensor failure is not detected normally, in order to check the operation of the speaker, “Woooo fire is a fire” with the same content as the fire alarm sound is output once as a speaker check notification sound at low volume.

  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. 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 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. Here, the normal state refers to a state at least during a fire alarm or a failure alarm.

  The alarm stop switch 20 includes a switch cover formed of a translucent member and a push switch (not shown) arranged inside the switch cover. That is, when the switch cover is pressed, the push switch is pressed. In the vicinity of the push switch inside the switch cover, an LED 22 for displaying an alarm or the like is arranged as indicated by a dotted line. When the LED 22 lights up, flashes, or blinks, the operating light passes through the switch cover portion of the alarm stop switch 20. This allows the operating state of the LED 122 to be visually recognized 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 addition, in the residential alarm 10 of FIG. 2, the smoke detector 16 is provided and the residential alarm which detects a fire based on the smoke generated with a fire is taken as an example. Detecting a house alarm equipped with a temperature detection element such as a thermistor, a house alarm detecting other physical phenomena associated with a fire, an alarm detecting a gas leak in addition to a fire, detecting an intruder, earthquake, or other abnormality Various types of alarm devices and combinations of these alarm devices are also included in the scope 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 a residential alarm according to the present invention provided in the alarm system of FIG. This is an example, and the separation and integration of each function can be performed arbitrarily. Each part or all of each function may be executed by software (program) or may be executed by hardware.

  In FIG. 3, the house guard is shown for the house guard 10-1 installed in the kitchen, but the other house guards 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 memory 32, a sensor unit 34, a notification unit 36, an operation unit 38, and A battery power source 40 is 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. 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, when the wireless communication unit 30 is used outside Japan, the wireless communication unit 30 has contents compliant with the standard of the assigned wireless station in that region.

  The antenna 31, the transmission circuit 42, and the transmission processing unit 60 are collectively referred to as a transmission unit, and the antenna 31, the reception circuit 44, and the reception processing unit 62 are collectively referred to as a transmission unit.

  The memory 32 includes a serial number 48, which is a serial number indicating the order of event signals, a transmission source code 50 serving as resident alarm identification information for identifying each resident alarm, and a resident alarm installed in a house as shown in FIG. The group code | symbol 52 for comprising the interlocking | linkage group which performs a interlocking | linkage alarm in 10-1 to 10-6 is stored.

  The serial number 48 is a code that is automatically generated and updated (for example, incremented) in accordance with a predetermined rule every time an event signal is transmitted. The event signal is relayed between alarm devices, particularly in wireless communication. However, since it is not directly related to the present invention, a detailed description thereof will be omitted.

  The source code 50 is, for example, a 26-bit multi-bit code code so that it does not overlap with any of the domestic alarms provided in Japan. For example, the serial number of the alarm or emergency earthquake warning device is used. We are using.

  Re-relay can be permitted or prohibited using the serial number 48 or the transmission source code 50, and by performing processing to avoid unnecessary communication, optimal relay can be performed as necessary. Further, for example, an event signal relayed and transmitted by the interlocking destination terminal is added with the source code of the interlocking source terminal in addition to the transmission source code of the interlocking destination terminal, and is re-started from the interlocking source terminal source code. It is also possible to detect and process whether transmission is possible. In addition, relay transmission permission and prohibition can be set for each event content indicated by the event signal.

  The group code 52 is a code that is set in common to a plurality of residential alarms constituting the interlocking group, and the group code included in the event signal received by the wireless communication unit 30 is the group code 52 registered in the memory 32. When they match, this event signal is processed as a valid signal, so unnecessary linkage with a resident alarm belonging to another group that is installed in a neighboring house or the like and does not require linkage 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. Registration of the group code 52 is performed by an appropriate method such as setting of an external switch or automatic registration using a communication function before shipment or before starting operation.

  The sensor unit 34 is provided with a smoke detector 16 that detects smoke and outputs a detection signal corresponding to the smoke concentration. As described above, instead of the smoke detector 16, the sensor unit 34 detects elements due to a temperature due to a fire and outputs a detection signal, and detects other physical phenomenon changes caused by the fire and outputs a detection signal. Various elements and sensors may be provided.

  The memory 32 stores a failure detection result by periodic failure monitoring processing (automatic inspection) by a built-in test when the low battery failure flag 78 or the sensor failure flag 80 detects each failure. In addition, a periodic notification timer 82 used for outputting a periodic failure alarm after detecting a low battery failure or a sensor failure is provided. The periodic notification timer 82 may be described and executed on a program executed by the processor 28 without being arranged in the memory 32.

  The notification unit 36 is provided with a speaker 56 that is an acoustic output device that outputs an alarm sound and the like, and an 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 and the alarm display is displayed. An alarm stop process is performed, such as stopping or a predetermined time after stopping the alarm sound.

  On the other hand, the alarm stop switch 20 functions as an inspection switch in a normal state in which a fire alarm or a failure alarm indicating an interlocking source or an interlocking destination is not performed, and if the alarm stop switch 20 is operated in this state, an inspection instruction operation (inspection instruction) is performed. Input) is detected, and it is determined whether or not the low battery failure flag 78 or the sensor failure flag 80 is stored in the memory 32 as the inspection result. If the failure flag is stored, the corresponding failure from the speaker 56 of the notification unit 36 is detected. A fault alarm such as a voice message indicating the contents is output.

  Further, when the failure flag is not stored in the memory 32, the inspection result is normal, so the same speaker inspection notification sound as the fire alarm sound for inspecting the speaker 56 is output once at a low volume.

  In addition, failure detection is not performed in the background, and when an operation of the alarm stop switch 20 is detected in a normal state (when inspection is instructed), predetermined failure detection operations including battery failure detection and sensor failure detection (inspection) Operation) may be performed to notify the result.

  In addition, when the alarm stop switch 20 is operated during the fault alarm, the fault alarm stop process is performed after the fault detection operation (check operation) including the battery fault detection and the sensor fault detection is performed again and the result is notified. You may do it. 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 made to recognize the failure state more clearly. At this time, when the failure state has been resolved (failure recovery), for example, a message such as “the failure has been resolved” may be output, and the process may proceed to failure stop (recovery) processing.

  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.

  In the processor 28, functions realized by program execution include an event detection unit 58, a transmission processing unit 60, a reception processing unit 62, an abnormality notification processing unit 64, a failure detection unit 66, a failure notification processing unit 72, and an inspection processing unit 74. And a failure alarm interruption unit 76 are provided, and the failure detection unit 66 is provided with functions of a low battery failure detection unit 68 and a sensor failure detection unit 70.

  The event detection unit 58 detects the presence or absence of a fire detected from the detection signal output of the sensor unit 34, the presence or absence of an alarm stop instruction input by the operation unit 38 or the presence or absence of an inspection instruction, and the detection signal output of the sensor unit 34 decreases to detect a fire. Detects events such as fire recovery, sensor failure, low battery failure, etc. when the condition is cleared. In addition, the event detection unit 58 receives the presence / absence of the event signal effective reception obtained as a result of decoding the event signals from the other residential alarm devices 10-2 to 10-6 via the reception circuit 44 and the reception processing unit 62, and the contents of the event. Is detected.

  The transmission processing unit 60 detects the fire from the detection signal output of the sensor unit 34 by the event detection unit 58, stops the alarm by the operation unit 38, and recovers the fire in which the detection signal output of the sensor unit 34 is reduced to eliminate the fire detection state. When a self event such as the above is detected, an event signal indicating the detected event content is transmitted from the antenna 31 to the linked house politician via the transmission circuit 42 of the wireless communication unit 30. In addition, the transmission processing unit 60 relays and transmits event signals that are effectively received from other mortgages as necessary.

  The reception processing unit 62 receives and decodes the event signals from the other residential alarm devices 10-2 to 10-6 from the antenna 31 via the reception circuit 44 of the wireless communication unit 30.

  The abnormality notification processing unit 64 receives a signal from the event detection unit 58 when the event detection unit 58 detects a fire as its own abnormality, outputs an alarm sound indicating the interlocking source from the speaker 56, and drives the LED 22 to turn on, for example. Then, an alarm indicating the interlocking source is displayed, and a fire event signal is transmitted to the other residential alarm devices 10-2 to 10-6.

  Specifically, 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, the abnormality notification processing unit 64 indicates that fact from the event detection unit 58. Based on the received signal, the alarm unit 36 is controlled to repeatedly output an alarm sound indicating the link source from the speaker 56, for example, a voice message of “Woo Woo is a fire”, and the LED 22 is turned on to indicate the link source. Alarm display control is performed, and further, a fire event signal is transmitted from the antenna 31 to the other residential alarm devices 10-2 to 10-6 via the transmission processing unit 64 and the transmission circuit 42.

  When the event detection unit 58 detects that the fire event signal has been effectively received from any of the other home alarm devices 10-2 to 10-6 by the reception circuit 44 of the wireless communication unit 30. In addition, an alarm sound (notification sound) indicating the link destination is repeatedly output from the speaker 56 of the notification unit 36, for example, a voice message “Wu Woo confirm that another fire alarm has been activated”, and at the same time, the LED 22 blinks, for example. To display an alarm indicating the link destination.

  Further, the abnormality notification processing unit 64 detects the operation of the alarm stop switch 20 during the output of the fire alarm sound indicating the interlock source or the fire alarm sound indicating the interlock destination, or other residential alarm devices 10-2 to 10-6. When the event signal indicating the alarm stop or the device event signal reception from any of the above is detected, 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. It should be noted that during the fire alarm indicating the interlock source, at least the output of the alarm sound may be continued even if the alarm stop event signal is received.

  The low battery failure detection unit 68 provided in the failure detection unit 66 is supplied from the battery power supply 40 directly or indirectly via a voltage detection circuit (not shown) at a predetermined measurement time interval, for example, T1 = 4 time interval. The power supply voltage is read by A / D conversion and compared with a predetermined threshold voltage. When the voltage is lower than the threshold voltage, the low battery failure detection is preliminarily determined (temporary determination), and the low battery failure detection is preliminarily determined (temporary determination). Is continuously detected a predetermined number of times, a low battery failure is detected (determined), and a low battery failure flag 78 is set and stored in the memory 32.

  The sensor failure detection unit 70 provided in the failure detection unit 66 reads the smoke concentration detection signal output from the smoke detection unit 16 of the sensor unit 34 by A / D conversion at a predetermined measurement time interval, for example, T2 = 1 second interval. Is stored in the buffer area of the memory 32. For example, every 10 minutes, the average value of the detected data for 10 minutes held in the buffer area of the memory 32 is obtained every predetermined time interval T3 = 10 minutes. When the output level is below a reference level (referred to as the zero point level), an output stop state is detected, and a failure of the sensor unit 34 is detected. A sensor failure flag 80 is set and stored in the memory 32.

  The reason why the 10-minute average value of the smoke concentration detection signal falls below the zero point is because of a failure such as failure of the light receiving element provided in the smoke detector 16, disconnection of the output signal line from the light receiving element, or stop of the light receiving amplifier. Because it is highly likely that this is due to the fact that it has

  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. In addition, disconnection of the output line to the speaker 56, other circuit failures, communication abnormalities, and the like can be similarly monitored. Such a failure is also collectively referred to as a sensor failure in the present embodiment because the same processing as the sensor failure is performed after detection.

  Thus, the detection processing of the low battery failure detection unit 68 and the sensor failure detection unit 70 in the present embodiment is automatically executed in the background as a build-in test.

  When the event detection unit 58 detects the low battery failure detection by the low battery failure detection unit 68, the failure notification processing unit 72 uses the speaker 56 of the notification unit 36 as a low battery failure alarm sound indicating the link source (failure source). For example, “Battery out of battery” is continuously output a plurality of times and the LED 22 is turned on, for example. Thereafter, the periodic notification timer 82 of the memory 32 is started, and a process of performing a sound output of “battery exhausted” and displaying by the LED 22 a plurality of times every predetermined time based on the low battery failure flag 78 stored in the memory 32. repeat.

  At the same time, the failure notification processing unit 72 transmits a low battery failure event signal to the other mortgage alarm devices 10-2 to 10-6, so that a low battery failure alarm indicating a link destination is used as an alarm sound. Is running out of battery "and a blinking display different from the interlock source is displayed.

  Further, when the event detecting unit 58 detects the sensor failure detection by the sensor failure monitoring unit 70, the failure notification processing unit 72 uses, for example, “sensor failure alarm sound indicating the link source (failure source) from the speaker 56 of the notification unit 36. "It is a pin failure" is output continuously several times, and the LED 22 is lit at the same time, for example.

  After that, the periodic notification timer 82 of the memory 32 is activated, and the process of outputting a voice “pick failure” and displaying the LED 22 a plurality of times is repeated at predetermined intervals based on the sensor failure flag 80 stored in the memory 32. At the same time, the failure notification processing unit 72 transmits a sensor failure event signal to the other mortgage alarm devices 10-2 to 10-6, so that the low battery failure alarm indicating the interlocking destination is used as an alarm sound. “Battery is exhausted” is output, and the flashing display is different from that of the link source.

  The inspection processing unit 74 detects that the low battery failure flag 78 is stored in the memory 32 when the event detection unit 58 detects an inspection instruction operation (inspection instruction input) by operating the alarm stop switch 20 in a normal state. In such a case, the failure alarm processing unit 72 continuously outputs, for example, “Battery out of battery” a plurality of times, and simultaneously turns on the LED 22, for example, and simultaneously sends a low battery failure event signal to the other housing alarm devices 10-2 to 10-10. By sending it to -6, the low battery failure alarm indicating the link destination is output as an alarm sound and “Pick another alarm is out of battery” is output, and the flashing display is different from the link source.

  Further, when the inspection processing unit 74 detects an inspection instruction operation (inspection instruction input) due to the operation of the alarm stop switch 20 by the event detection unit 58, or when it detects that the sensor failure flag 80 is stored in the memory 32. Causes the failure notification processing unit 72 to continuously output, for example, “It is a pin failure” a plurality of times, and simultaneously turns on the LED 22, for example, and simultaneously transmits a sensor failure event signal to the other residential alarm devices 10-2 to 10-6. As a result, the low battery failure alarm indicating the link destination is output as a warning sound, and a separate alarm is out of order, and a flashing display different from the link source is displayed.

  In this way, when the alarm stop switch 20 is operated for inspection, since there is always a person in front of the house alarm, it is possible to reliably notify a low battery failure or a sensor failure.

  Further, when the inspection processing unit 74 detects an inspection instruction operation (inspection instruction input) by the operation of the alarm stop switch 20 by the event detection unit 58, neither the low battery failure flag 78 nor the sensor failure flag 80 is stored in the memory 32. In this case, in order to check the speaker to confirm that the alarm sound is normally output from the speaker 56 of the notification unit 36, “Woo Woo Fire Alarm Device” has the same contents as the fire alarm sound. "Check that has been activated" is output as a sound for checking the speaker once at a lower volume than the actual fire alarm sound.

  When the event detection unit 58 detects an inspection instruction operation (inspection instruction input) by the operation of the alarm stop switch 20, the inspection processing unit 74 causes the failure detection unit 66 to detect the failure of the low battery and the sensor failure (inspection). ) May be executed again, and a fault alarm may be output when a fault is detected, and an alarm sound for speaker inspection may be output when normal is detected. Thereby, the latest inspection result can be notified.

  The failure alarm interruption unit 76 is configured to output the other battery alarms 10-2 to 10- in the event detection unit 58 during the output of the low battery failure alarm or the sensor failure alarm based on the inspection instruction operation of the alarm stop switch 20 by the inspection processing unit 74. For example, “Woo Woo another fire alarm has been activated. Check if the low battery fault alarm or sensor fault alarm is interrupted and an interlocking destination is indicated when valid reception of an event signal indicating a fire from 6 is detected. ”Is output.

  Further, the failure alarm interruption unit 76 detects the normality with respect to the inspection instruction operation of the alarm stop switch 20 by the inspection processing unit 74 and outputs another alarm signal from the speaker 56 while the alarm detection sound is output from the speaker 56. When the effective reception of the event signal indicating the fire from 10-2 to 10-6 is detected, the output of the speaker check notification sound is interrupted and the fire alarm sound indicating the interlock destination is output.

  Here, as the fire alarm sound to be output after the trouble alarm interruption unit 76 interrupts the trouble alarm sound or the alarm sound for speaker inspection, as a fire alarm sound of a predetermined pattern including a message indicating that a fire has occurred during inspection, For example, “Woo Woo, another fire alarm has been activated during the inspection. Check” is output.

  As a result, it is possible to accurately recognize that another fire alarm 10-2 to 10-6 has detected the occurrence of a fire during the inspection, and take quick action. Also, if the inspection result is normal, the alarm sound for speaker inspection is output and “Woo-woo fire alarm is activated” is output at a low volume, but it is under inspection after the interruption. Since a fire alarm sound such as “Woo Wow another fire alarm was activated during the inspection” is shown, indicating that the occurrence of a fire was detected at another location, clearly from the alarm sound for speaker inspection You can distinguish and know the fire.

  It should be noted that the interruption of the failure alarm sound or the speaker inspection notification sound based on the occurrence of a fire is interrupted without waiting for the end even in the middle of the alarm sound, and a fire alarm sound indicating the occurrence of a fire is output.

  FIG. 4 is an explanatory diagram schematically showing the event signal format used for the linked alarm in the present 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 to each terminal (residential alarm). Further, the serial number 48 is generated asynchronously in each of the residential alarms. The serial number 48 is for managing event signal relay processing, etc., mainly in wireless communication, between the residential alarm devices 10-1 to 10-6, but is not directly related to the present invention, and therefore will be described in detail. Is omitted.

  The transmission source code 50 is, for example, a 26-bit code used as the home alarm identification information, and uses, for example, the serial number of the home alarm. The group code 52 is, for example, an 8-bit code. For example, the same group code is set for each of the residential alarm devices 10-1 to 10-6 in FIG.

  As the group code 52, in addition to setting the same group code to the same group of house alarms, for example, a reference code common to the house alarms constituting a predetermined group and a transmission source unique to each house alarm A different group code may be used for each residential alarm obtained from the calculation with the code. That is, any code can be used as long as each terminal (residential alarm) receiving the event signal can determine whether or not it is a signal from a terminal of the same group as itself based on the terminal. good.

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, 001 = fire 010 = gas leak 011 = alarm stop (fire alarm stop, gas leak alarm stop, fault alarm stop)
100 = recovery (fire recovery, gas leak recovery, failure recovery)
101 = sensor failure 110 = low battery failure. Here, 000 is not used for event detection, for example, for regular notification.

  By increasing the number of bits of the event code 54 to 4 bits and 5 bits, more event contents can be expressed. For example, recovery event codes may be divided into fire recovery, gas leak recovery, and failure recovery.

  In an alarm device that detects an abnormality other than a fire, the above-mentioned 001 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 of different abnormality types to be detected can be mixed in the same group.

  5 to 8 are flowcharts showing a schematic example of the monitoring process in the residential alarm 10 of FIG. In FIG. 5, when the power supply by the battery power source 40 of the mortgage alarm device 10 is started, various settings including initialization, self-diagnosis, and prohibition mode setting are read in step S1, and if there is no abnormality. In step S2, the presence or absence of a fire is detected.

  When the smoke detection signal output from the sensor unit 34 exceeds a predetermined fire level, a fire is detected. In step S2, fire detection is determined, and the process proceeds to step S3. After wirelessly transmitting an event signal including a source code to be identified, a group code, and an event code indicating a fire to another house alarm device, an alarm sound such as a voice message or a buzzer sound from the speaker 56 of the notification unit 36 in step S4 A fire alarm indicating the interlocking source is output by, for example, an alarm display by turning on the LED 22.

  Subsequently, in step S5, the presence or absence of a fire recovery in which the smoke detection signal from the sensor unit 34 is reduced to cancel the fire detection state is detected. When a fire recovery is detected, a serial number, a transmission source code, and a group are detected in step S6. After transmitting the event signal including the code and the event code indicating the fire recovery to the other home alarm device, the fire alarm indicating the interlocking source by the alarm sound from the speaker 56 and the alarm display by lighting the LED 22 is stopped in step S7. . The alarm display by the LED 22 may be turned off after a predetermined time has elapsed.

  Subsequently, in step S8, whether or not an alarm stop instruction operation of the alarm stop switch 20 is detected is detected, and when a switch operation is detected, the presence or absence of an alarm is detected in step S9. When an alarm is detected in step S9, 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 another house alarm, and the process proceeds to step S11. Then, the alarm sound output indicating the interlocking 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.

  If it is detected in step S9 that an alarm is not being issued, the operation of the alarm stop switch detected in step S8 is recognized as an inspection instruction operation, and a predetermined inspection operation is performed to notify the result. However, illustration is abbreviate | omitted.

  Subsequently, the process proceeds to step S12 in FIG. 6 to detect the presence / absence of effective reception of an event signal indicating a fire transmitted or relay-transmitted from another house alarm device. When the effective reception of an event signal indicating a fire from another house alarm is detected, the process proceeds to step S13 to output an alarm sound 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 detected whether or not the event signal indicating the fire restoration transmitted or relayed from another house police device is valid. If the validity of the event signal indicating the fire restoration is detected, the process proceeds to step S15. The alarm display by the alarm sound output from the speaker 56 and the blinking of the LED 22 which is performed as an alarm at the interlocking destination is stopped.

  Next, in step S16, the presence or absence of effective reception of an event signal indicating an alarm stop transmitted or relayed from another resident alarm is detected, and when the effective reception of an event signal indicating an alarm stop is detected, the process proceeds to step S17. The process proceeds to determine whether or not an alarm is present. When the alarm is determined, the process proceeds to step S18 to stop the alarm sound output as the interlocking destination and to stop the alarm display.

  Subsequently, the process proceeds to step S19 in FIG. 7, where it is detected whether or not there is a low battery failure. When a low battery failure is detected, the process proceeds to step S20 where the low battery failure flag 78 is set and stored in the memory 32 and the periodic notification timer 82 is set. to start.

  Subsequently, in step S21, a low battery failure alarm output indicating a failure source and an alarm display are performed, and then, in step S22, a low battery failure event signal is transmitted to another residential alarm.

  Subsequently, the process proceeds to step S23, where the presence or absence of a sensor failure is detected. When a sensor failure is detected, the process proceeds to step S24 where the sensor failure flag 80 is set and stored in the memory 32 and the periodic notification timer 82 is started.

  Subsequently, in step S25, a sensor fault alarm output and alarm display indicating the source of the fault are performed, and then in step S26, a sensor fault event signal is transmitted to another residential alarm.

  Subsequently, in step S27, it is detected whether or not the low battery failure flag 78 or the sensor failure flag 80 is set in the memory 32. If any failure flag is stored, the process proceeds to step S28, and the periodic ringing started in step S20 or S24. The timer 82 detects the presence or absence of a regular ringing timing after a predetermined time has elapsed, and if the regular ringing timing is detected, the process proceeds to step S29. If the low battery failure flag is set at that time, a low battery failure alarm is output and a sensor failure flag is output. If is set, a sensor failure alarm is output.

  Subsequently, the process proceeds to step S30 in FIG. 8, where the presence / absence of an inspection instruction operation by the operation of the alarm stop switch 20 is detected. When the inspection instruction operation is detected, the process proceeds to step S31, and the presence / absence of storage of a failure flag in the memory 32 is detected. If it is detected that the failure flag is not stored, the process proceeds to step S32, and the normal sound notification, for example, the alarm sound for speaker inspection, is the same as the fire alarm sound. To notify the user that the house alarm 10 operates normally.

  If the storage of the failure flag is detected in step S31, the process proceeds to step S33. If the storage of the low battery failure flag 78 is detected at that time, a low battery failure alarm is output, and if the storage of the sensor failure flag 80 is detected. A sensor failure alarm is output.

  During the output of the fault alarm, the presence / absence of the end of the fault alarm output is detected at step S34, and when the end of the fault alarm is detected, the presence / absence of effective reception of the fire event signal from another house alarm is detected at step S35. If the end of the failure alarm output is detected in step S35 without detecting the effective reception of the fire event signal in step S35, the process returns to step S2 in FIG.

  On the other hand, when the effective reception of the fire event signal from the other house alarm device is detected during the output of the failure alarm sound in step S35, the process proceeds to step S36, and the output of the failure alarm sound from the speaker 56 is interrupted. In S37, a fire alarm sound indicating the interlock destination and an alarm display are performed. The fire alarm sound includes a message indicating that a fire has occurred during the inspection.

  During the output of the fire alarm sound, the presence or absence of the alarm stop is detected in step S38, and when the alarm stop is detected, the process proceeds to step S39 to stop the fire alarm sound and the alarm display. The detection of the alarm stop in step S38 is performed by detecting the operation instruction input of the alarm stop switch 20, detecting the effective reception of the fire recovery event signal from another house alarm, or the alarm stop event signal from another house alarm. This is a case where one of the effective reception detections is determined, and the details thereof are the contents shown in steps S5 to S11 in FIG. 5 and steps S14 to S18 in FIG.

  In the flowcharts of FIGS. 6 to 8, processing when an event signal indicating a low battery failure or a sensor failure is received from another residential alarm is omitted, but a low battery failure or a When effective reception of an event signal indicating a sensor failure is detected, a low battery failure alarm or a sensor failure alarm indicating a linkage destination (failure destination) is performed with an alarm sound and an alarm display.
