Description

The present invention relates to an alarm device that detects an abnormality such as a fire and outputs an alarm sound including a voice message and displays an alarm.

  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, a sensor unit and an 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 including a voice message is output from the alarm unit. Because it is designed to output and fire monitoring and alarm can be performed with a single residence guard without the need for dedicated receiving equipment, etc., it is easy to install and inexpensive, and with the obligatory installation in ordinary houses Widely used.

  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 interlocking house alarm system, when a fire is detected by the house alarm, the interlocking house alarm detecting the fire detects a predetermined pattern of fire alarm sound including a message and an alarm sound, for example, “PPP”. “It is a fire.” On the other hand, the alarm device linked to it outputs a fire alarm sound indicating the interlock destination, for example, “A separate alarm device has been activated”.

According to the alarm device of the present invention , when a fire is detected as an abnormality, for example, a speaker functioning as an acoustic converter outputs a predetermined pattern of alarm sound consisting of a sweep sound such as “Peepy Fire is Fire” and a voice message. However, at the same time, an alarm display according to the display pattern such as blinking, blinking, or luminance change corresponding to the sound pressure of the alarm sound "Peepy Fire is Fire" is performed by the indicator such as LED, and sound and light are emitted. Synchronized alarm notification is performed.

  This alarm output, which synchronizes sound and light, is output once at a low volume, as in the case of a fire, because of the speaker test even when the inspection result is normal when the switch is operated under normal conditions. Therefore, the user has an opportunity to learn the alarm output in which sound and light are synchronized through the inspection operation.

As a result, a malfunction that stops the sound from the speaker occurs. If a fire is detected in this state, the speaker will not emit an alarm sound, but the LED will generate an alarm sound “Peepy Fire is Fire”. An alarm is displayed with a blinking pattern, blinking pattern, or luminance change pattern according to the corresponding display pattern, and the user can infer `` Ppy fire is fire '' by looking at the light of the LED display pattern, Even if a failure that does not produce sound from the speaker occurs, an alarm function corresponding to a voice message can be maintained.

  FIG. 1 is an explanatory view showing the appearance of a residential alarm according to the first invention of the present application, which is a so-called stand-arrow type that is installed and used alone. FIG. 1 (A) is a front view and FIG. 1 (B) is a front view. A side view is shown. The side provided with the attachment hook 15 is the upper side.

  In FIG. 1, the housing of the residential alarm 10 according to this embodiment includes a cover 12 and a main body 14. A plurality of smoke inlets are opened around a portion protruding in the center of the cover 12, and a smoke detecting section 16 is disposed inside the cover 12 so that a fire is detected when smoke from the fire reaches a predetermined concentration. Yes. As the smoke detector 16, for example, a known scattered light smoke detector mechanism can be applied.

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

  The alarm stop switch 20 also has a function as an inspection switch for instructing notification of the inspection result of the residential alarm 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, the result of the automatic inspection stored in the memory 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. operating state of the transmission to LED 22 is to be visible 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.

  The home alarm device 10 monitors the monitoring area corresponding to the installation location of the house, and when a fire occurs, detects the fire and starts an alarm. Detecting this fire and initiating an alarm is referred to as “reporting” at the home alarm.

  As an alarm operation of the home alarm device 10, for example, a fire alarm sound of a predetermined pattern consisting of a sweeping sound and a voice message such as “It is a fire. Here, the first half “Peepy” is a sweep warning sound in which the signal amplitude of the audio signal driving the speaker is constant and the frequency changes at, for example, 2 to 3 KHz. In this embodiment, the alarm display associated with the fire alarm of the resident alarm 10 is a display pattern corresponding to the change state of the output sound pressure of the fire alarm sound “PPP fire is a fire” output from the speaker 36. The LED 22 is driven to display a fire alarm, and the way the LED 22 shines is synchronized with the fire alarm sound.

  When the alarm stop switch 20 is operated in a state where the house alarm 10 is emitting an alarm sound, the alarm sound and alarm display stop processing is performed.

  In addition, the house alarm 10 automatically performs a failure detection process (automatic check) for determining a low battery failure from a drop in the voltage supplied from the battery power source in the background as a built-in test at predetermined intervals. If detected, a low battery failure alarm is output.

  The low battery failure alarm outputs, for example, “Battery is out of battery” several times from the speaker of the Dwelling Unit 10 and turns on the LED, for example, and then the “Battery is out of battery” every predetermined time by the periodic notification timer. The process of outputting the sound and displaying with the LED multiple times is repeated.

  Moreover, when operating the alarm stop switch 20 that functions as an inspection switch in a normal state, the home alarm device 10 determines a low battery failure by a failure detection process automatically executed in the background as a built-in test and stores it in the memory. In this case, as a low battery failure alarm, for example, “Battery is out of battery” is continuously output a plurality of times, and the LED 22 is lit, for example. On the other hand, when the low battery failure is not detected normally, to check the speaker operation, the same content as the fire alarm sound “Peepy fire is a fire” is used as a speaker check alarm sound at a lower volume than the low battery failure alarm sound. Output once. Also in this case, the LED 22 is inspected and driven by the display pattern corresponding to the change state of the output sound pressure of the alarm sound for speaker inspection output from the speaker 36 “Peepy Fire is Fire”. It is tuned to the sound.

  By synchronizing the lighting method of the LED 22 with the alarm sound for speaker inspection during such an inspection operation, the user has an opportunity to learn the alarm output in which the sound and the light are synchronized through the inspection operation. Therefore, in the unlikely event that a fire is detected in a state where there is no sound from the speaker 36, it can be expected that the alarm content such as “Peepy fire is fire” from the way the LED 22 shines will be expected. .

  In addition, the house alarm 10 automatically executes a failure detection process (automatic inspection) for detecting a sensor failure in the background every predetermined cycle as a built-in test, and outputs a sensor failure alarm when a sensor failure is detected. The sensor failure detected by the home alarm device 10 includes the presence or absence of a sensor, detection circuit, audio notification circuit failure, sensitivity abnormality due to contamination, and the like.

  In addition, when the alarm device 20 operates the alarm stop switch 20 that functions as an inspection switch in a normal state, the house alarm 10 detects a sensor failure by a failure detection process automatically executed in the background as a built-in test and stores it in the memory. For example, a “beep failure” sound is output from the speaker continuously for a plurality of times, for example, and the LED 22 is lit, for example, and then a periodic notification timer outputs a “beep failure” sound output and the LED 22 Repeat the lighting display multiple times.

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

  In addition, in the residential alarm 10 of FIG. 1, 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.

  FIG. 2 is a block diagram showing an embodiment of the residential alarm shown in 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. 2, the housing alarm 10 is provided with a processor 24 known as a one-chip CPU. The processor 24 has a memory 26, a sensor unit 28, a notification unit 30, an operation unit 32, a transfer unit 34, and a battery power source. 35 is provided.

  The sensor unit 28 is provided with a smoke detection unit 16 that detects smoke and outputs a detection signal corresponding to the smoke concentration. As described above, the sensor unit 28 replaces the smoke detection unit 16 with a temperature caused by a fire. It is also possible to provide various elements and sensors that detect a change and detect a change in other physical phenomenon caused by a fire and output a detection signal.

The memory 26 stores a failure detection result by periodic failure monitoring processing (automatic inspection) automatically executed in the background as a built-in test when the low battery failure flag 56 or the sensor failure flag 58 detects each failure. Is done. In addition, a periodic notification timer 62 used for outputting a periodic failure alarm after detecting a low battery failure or a sensor failure is provided. The periodic notification timer 62 may be described and executed on a program executed by the processor 24 without being arranged in the memory 26 .

  Furthermore, in this embodiment, an alarm sound failure flag 60 is stored in the memory 26 as a failure detection result by periodic failure monitoring processing (automatic inspection) that is automatically executed in the background as a build-in test. Reference numeral 60 denotes a failure in the speaker system in which sound is not output from the speaker 36 provided in the notification unit 30.

  The notification unit 30 is provided with a speaker 36 that is an acoustic output device that outputs an alarm sound and the like, and an LED 22 that displays an alarm. The speaker 36 outputs various voice messages, alarm sounds, and the like stored in the memory 26 from a voice synthesis circuit unit (not shown) via an amplification unit (not shown). The LED 22 is driven by a display pattern corresponding to a change state of the output sound pressure of the fire alarm sound from the speaker 36 and displays an abnormality alarm such as a fire. For indications other than abnormalities such as a fire, the LED 22 is lit, blinks, or blinks. 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 32 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 30 through the speaker 36 or when an alarm display is performed through the LED 22.

  On the other hand, the alarm stop switch 20 functions as an inspection switch in a normal state where no fire alarm or failure alarm is being performed. When the alarm stop switch 20 is operated in this state, an inspection operation (inspection instruction input) is detected, and a built-in test As a result, the inspection result that is automatically executed in the background and stored in the memory 26 is notified. The notification of the inspection result includes a failure notification and a normal notification, and at the time of normal notification, an inspection display of a display pattern corresponding to an alarm sound for speaker inspection and a change state of the output sound pressure is performed.

  The transfer unit 34 outputs a transfer signal to other devices when a fire is detected and an alarm is given. As the transfer signal, for example, a no-voltage signal is output when the relay contact is turned on.

  The battery power source 35 uses, for example, a lithium battery or an alkaline battery with a predetermined number of cells, and supplies power to each part as necessary. The battery capacity is low power consumption of the entire circuit part in the residential alarm 10. For example, the battery life of 10 years is guaranteed.

  The processor 24 is provided with functions of an event detection unit 38, a monitoring processing unit 40, and an inspection processing unit 46 as functions realized by executing the program. The monitoring processing unit 40 has an alarm sound control unit 42 and an alarm display control. The function of the unit 44 is provided.

  The event detection unit 38 detects the presence or absence of a fire detected from the detection signal output of the sensor unit 28, the presence or absence of an alarm stop instruction input or inspection instruction input by the operation unit 32, and the detection signal output of the sensor unit 28 decreases to detect a fire. Events such as a fire recovery, a sensor failure, a low battery failure, and an alarm sound failure of the speaker 36 are detected.

  When the event detection unit 38 detects a fire as its own abnormality, the monitoring processing unit 40 causes the alarm sound control unit 42 to output an alarm sound indicating a fire from the speaker 36, and the alarm display control unit 44 drives the LED 22. Fire alarm display.

  More specifically, when the event detection unit 38 detects a fire based on the smoke detection signal of the smoke detection unit 16 provided in the sensor unit 28, the monitoring processing unit 40 indicates that fact from the event detection unit 38. Based on this signal, the alarm sound control unit 42 controls the alarm unit 30 to repeatedly output an alarm sound indicating a fire from the speaker 36, for example, a voice message “Peepy fire is fire”, from the speaker 36, and an alarm display control unit 44, the LED 22 is driven in accordance with a display pattern corresponding to the change state of the output sound pressure of the fire alarm sound, and control is performed to display an alarm indicating fire.

  FIG. 3 is an explanatory diagram showing a fire alarm sound by the alarm sound control unit 42 of FIG. 2 and a display pattern of the LED 22 by the alarm display control unit 44.

  FIG. 3 (A) is a fire alarm sound “Peepy fire is a fire”, which is actually a voice signal output from a voice synthesis circuit and has an analog amplitude waveform corresponding to the voice message.

  FIG. 3B is a display pattern of the LED 22 generated based on the fire alarm sound of FIG. 3A, and the driving current is applied to the LED 22 corresponding to the change state (signal level) of the output sound pressure of the fire alarm sound. The display pattern is flashing, blinking, or changes in luminance.

  For example, “Peepy” in the first half is a sweep sound whose amplitude is constant and changes from a low frequency to a high frequency, and this change in frequency is expressed by linearly increasing luminance. Next, “I am a fire” is repeated, but the brightness is increased at the “fire” part, and the brightness is reduced at the “is” part.

  FIG. 3C is another example of the LED display pattern. The LED display pattern of FIG. 3B has a light-off portion, but the LED display pattern of FIG. 3C does not have a light-off portion. The display pattern corresponds to the sound.

In addition, as an LED display pattern corresponding to a fire alarm sound, it is not limited to FIG. 3 (B) (C), The pattern used as the appropriate lighting method which can grasp | ascertain the message content of a fire alarm sound may be sufficient. The LED display pattern may be generated by waveform processing of an audio signal output to the speaker 36 to drive the LED 22, or display pattern data such as shown in FIGS. 3B and 3C is stored in the memory 26 in advance. In addition, the LED 22 may be driven by reading out at the time of a fire alarm.

  Further, when the monitoring processing unit 40 detects the operation of the alarm stop switch 20 during the output of the fire alarm sound, the monitoring processing unit 40 stops the output of the fire alarm by the voice message from the speaker 36 and the alarm display of the LED 22. At this time, the alarm display by the LED 22 may be stopped after continuing for a predetermined time.

  Further, the event detection unit 38 directly or indirectly through a voltage detection circuit (not shown) at a predetermined measurement time interval, for example, T1 = 4 time intervals, as a low battery failure detection process automatically executed in the background as a build-in test. In addition, the power supply voltage supplied from the battery power source 35 is read by A / D conversion and compared with a predetermined threshold voltage. When the voltage is lower than the threshold voltage, detection of a low battery failure is preliminarily determined (provisional determination). When the preliminary determination (provisional determination) of failure detection continues for a predetermined number of times, a low battery failure is detected (determined), and a low battery failure flag 56 is set and stored in the memory 26.

  Further, the event detection unit 38 performs a sensor failure detection process automatically executed in the background as a build-in test, and the smoke concentration output from the smoke detection unit 16 of the sensor unit 28 at a predetermined measurement time interval, for example, T2 = 1 second interval. The detection signal is read by A / D conversion and held in the buffer area of the memory 26. For example, the average value of detection data for 10 minutes held in the buffer area of the memory 26 every predetermined time interval T3 = 10 minutes. When the average value falls below a predetermined reference level (referred to as the zero point level), a failure of the sensor unit 28 is detected as being in an output stop state, and the sensor failure flag 58 is set and stored in the memory 26.

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 28 , a sensor failure can be similarly detected by various processes. Such a failure is also collectively referred to as a sensor failure in the present embodiment because processing similar to that for a sensor failure is performed after detection.

  In addition, the event detection unit 38 performs a warning sound failure detection process automatically executed in the background as a build-in test, and includes an audio signal including a speaker 36 (not shown) at a predetermined measurement time interval, for example, the same T1 = 4 hour interval as the low battery failure detection Test the output system to detect the presence of a fault. As a test of the audio output system, for example, a DC test signal that does not produce sound is output to the speaker 36, the detected voltage of the speaker driving current is read by A / D conversion, and compared with a predetermined threshold voltage, and the threshold voltage is below this threshold voltage. Alarm sound failure detection due to disconnection of the speaker output line is preliminarily determined (temporary determination), and when the alarm sound failure detection preliminary determination (temporary determination) continues for a predetermined number of times, the alarm sound failure is detected (confirmed) Then, the low battery failure flag 56 is set and stored in the memory 26.

  When the event detection unit 38 determines that a warning sound failure without sound from the speaker 36 and the warning sound failure flag 60 is stored in the memory 26, the display control unit 44 provided in the monitoring processing unit 40 is the event detection unit 38. When a fire is detected and a signal indicating that is received, the drive current flowing through the LED 22 is increased, and the drive current of the display pattern corresponding to the fire alarm sound shown in FIG. 3 (B) or (C) is increased. To increase brightness. Thereby, even in a situation where no fire alarm sound is emitted from the speaker 36, the light from the LED 22 is strengthened, so that the fire alarm can be more reliably transmitted to the user.

  Here, when the alarm sound failure is detected, the increase in the drive current that flows to the LED 22 is within a range that does not exceed the drive current for alarm sound output that flows to the speaker 36, and the speaker 36 is functioning normally. It is assumed that the battery power supply 35 is consumed at an equivalent level or lower.

  Although the failure detection by the event detection unit 38 in the present embodiment is automatically executed in the background after a built-in test, when the operation of the alarm stop switch 20 is detected in a normal state without performing this (inspection) When an instruction operation is detected), a predetermined failure detection operation (inspection operation) including battery failure detection, sensor failure detection, and alarm sound failure detection may be performed to notify the result.

  In addition, when an operation of the alarm stop switch 20 is detected during a failure alarm, a failure detection operation (inspection operation) including battery failure detection, sensor failure detection, and alarm sound failure detection is performed again and the result is notified. A failure alarm stop process may be performed later. 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.

Monitoring processor 40, if the low battery failure event detecting unit 38 is detected, receive a signal indicating the event detecting unit 38, the low from the speaker 36 of the alert section 30 by the warning sound controller 42 based on this For example, “battery is exhausted” is continuously output a plurality of times as an alarm sound for battery failure, and the LED 22 is lit, for example, by the alarm display control unit 44. Thereafter, the periodic notification timer 62 of the memory 26 is started, and a sound output of “battery dead” and display by the LED 22 are performed a plurality of times at predetermined intervals based on the low battery failure flag 56 stored in the memory 26. Repeat.

When the event detection unit 38 detects a sensor failure and receives a signal indicating that fact, the monitoring processing unit 40 receives, for example, “peep” as a sensor failure alarm sound from the speaker 36 of the notification unit 30 by the alarm sound control unit 42. “It is a failure” is continuously output a plurality of times, and the alarm display control unit 44 turns on the LED 22, for example. After that, the periodic notification timer 62 of the memory 26 is started, and a process of performing voice output of “pick failure” and display by the LED 22 a plurality of times every predetermined time based on the sensor failure flag 58 stored in the memory 26 is repeated. .

The inspection processing unit 46 receives a signal indicating that the inspection operation (inspection instruction input) by the operation of the alarm stop switch 20 in the normal state is detected by the event detection unit 38, and the low battery failure flag 56 is further stored in the memory 26. When it is detected that the data is stored, the alarm sound control unit 42 continuously outputs, for example, “battery is exhausted” from the speaker 36 of the notification unit 30 multiple times, and the alarm display control unit 44 simultaneously turns on the LED 22, for example. Let

Further, the inspection processing unit 46 receives a signal indicating the building when the event detection unit 38 detects an inspection operation (inspection instruction input) by the operation of the alarm stop switch 20, and further stores a sensor failure flag 58 in the memory 26. If it is detected, the alarm sound control unit 42 causes the speaker 36 of the notification unit 30 to continuously output, for example, “pick failure” a plurality of times, and the alarm display control unit 44 turns on the LED 22, for example.

  Thus, when the operation of the alarm stop switch 20 is detected 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, the inspection processing unit 46 detects the inspection instruction operation (inspection instruction input) by the operation of the alarm stop switch 20 by the event detection unit 38, receives a signal indicating that, and the alarm sound failure flag 60 is stored in the memory 26. When it is detected that there is no sound from the speaker 36, the alarm display control unit 44 causes the LED 22 to blink, for example.

In addition, the inspection processing unit 46 detects the inspection operation (inspection instruction input) by the operation of the alarm stop switch 20 by the event detection unit 38, receives a signal indicating the building, and the low battery failure flag 56 is also stored in the memory 26. When it is detected that the flag 58 is not stored, it is determined as normal. In this case, the alarm check is performed by the alarm sound control unit 42 to confirm that the alarm sound is normally output from the speaker 36 of the notification unit 30. Therefore, “Peepy fire is a fire” with the same content as the fire alarm sound is output once at a lower volume than the failure alarm sound as an alarm sound for speaker inspection. At the same time, the inspection processing unit 46 drives the LED 22 to emit light with the display pattern shown in FIG. 3B or FIG. 3C corresponding to the change state of the output sound pressure of the alarm sound for speaker inspection by the alarm display control unit 44. As a result, the user is unconsciously trained to learn fire alarms using sound and light.

  When the event detection unit 46 detects an inspection operation (inspection instruction input) due to the operation of the alarm stop switch 20 and receives a signal indicating that, the inspection processing unit 46 instructs the event detection unit 38 to output a low signal. Execute the fault detection process (inspection) for battery faults and sensor faults again. If a fault is detected, a fault warning is output. If normal is detected, an alarm sound for speaker check and a warning sound pattern display are displayed. May be. Thereby, the latest inspection result can be notified.

  4 to 6 are flowcharts showing an example of the monitoring process in the residential alarm 10 of FIG. In FIG. 4, when the power supply by the battery power supply 35 of the mortgage alarm device 10 is started, initialization, self-diagnosis, and reading of various settings are executed in step S1, and if there is no abnormality, the process proceeds to step S2 to monitor fire. doing.

  When the smoke detection signal output from the sensor unit 28 exceeds a predetermined fire level, a fire is detected. In step S2, it is determined that a fire detection has been detected, and the process proceeds to step S3. It is determined whether or not an alarm sound failure has been detected based on the storage of the failure flag 60. If an alarm sound failure has been detected, the process proceeds to step S4, and a setting is made to increase the drive current flowing through the LED 22. Of course, if no alarm sound failure is detected, the process of step S4 is skipped.

  Subsequently, the process proceeds to step S5, where a fire alarm is output from the speaker 36 of the notification unit 30 by a fire alarm sound such as a voice message or a buzzer sound, and a disaster alarm display that drives the LED 22 so as to emit light with a display pattern corresponding to the fire alarm sound. Let

  Subsequently, in step S6, the presence or absence of a fire restoration is detected in which the smoke detection signal from the sensor unit 28 is lowered to cancel the fire detection state. When a fire restoration is detected, an alarm sound from the speaker 36 is detected in step S7. The fire alarm by the alarm display of LED22 is stopped. In addition, you may stop the fire alarm display by LED22 after predetermined time progress.

  Subsequently, in step S8, whether or not the alarm stop instruction operation of the alarm stop switch 20 during the alarm is detected is detected. When the presence of the switch operation is detected, the process proceeds to step S9 to stop the output of the fire alarm sound from the speaker 36, and the LED 22 Turn off the fire alarm display by turning on. The LED 22 may be turned off after a predetermined time has elapsed.

  Subsequently, the process proceeds to step S10 in FIG. 5, where it is detected whether or not there is a low battery failure. When it is detected that there is a low battery failure, the process proceeds to step S11 and the low battery failure flag 56 is set in the memory 26 and stored. Start up. In step S12, a low battery failure alarm sound is output and an alarm is displayed.

  Subsequently, the process proceeds to step S13, where the presence / absence of a sensor failure is detected. When the sensor failure is detected, the process proceeds to step S14 where the sensor failure flag 58 is set and stored in the memory 26 and the periodic notification timer 62 is started. After that, the process proceeds to step S15 to output a sensor failure alarm sound and display an alarm.

Subsequently, the process proceeds to step S16, where the presence or absence of an alarm sound failure is detected. When the alarm sound failure is detected, the process proceeds to step S17, where the alarm sound failure flag 60 is set and stored in the memory 26 and the periodic notification timer 62 is activated. Then, the process proceeds to step S18, where an alarm output of an alarm sound failure is performed. In this case, since there is no sound from the speaker 36, an alarm display is performed only by blinking of the LED 22. Here, in the case of detecting an alarm sound failure, since the drive current flowing through the LED 22 is increased, strong light is emitted from the LED 22 .

  Subsequently, the process proceeds to step S19 in FIG. 6, and it is detected whether or not the low battery failure flag 56, the sensor failure flag 58, or the alarm sound failure flag 60 is stored in the memory 26, and when the storage of any failure flag is detected. The process proceeds to S20, where it is determined whether or not the regular ringing timer 62 started in step S11, S14 or S17 is a regular ringing timing when a predetermined time has passed. If the regular ringing timing is determined, the process proceeds to step S21, at which time the low battery failure flag If 56 is stored, a low battery failure alarm is output. If a sensor failure flag 58 is stored, a sensor failure alarm is output. If an alarm sound failure flag 60 is stored, an alarm sound failure with only a failure display is displayed. An alarm is output.

  Subsequently, the process proceeds to step S22, in which the presence or absence of an inspection operation by the alarm stop switch 20 functioning as an inspection switch in the normal state is detected. When the presence of the inspection operation is detected, the process proceeds to step S23. When it is detected that neither the failure flag 58 nor the alarm sound failure flag 60 is stored, the failure detection is not detected (normal), and the process proceeds to step S24. And the LED 22 is driven to emit light in accordance with a display pattern corresponding to the change state of the output sound pressure of the alarm sound for speaker inspection, and the inspection display is performed.

On the other hand, when it is detected that the low battery failure flag 56, the sensor failure flag 58 or the alarm sound failure flag 60 is stored in the memory 26 , the presence of the failure is detected, and the process proceeds to step S25. For a fault or sensor fault, a fault warning sound including a message is output, the LED 22 is blinked, for example, and when it is detected that the warning tone fault flag 60 is stored in the memory 26, a fault warning sound is output from the speaker 36. In this case, the failure is notified only by blinking of the LED 22, for example.

FIG. 7 is an explanatory diagram showing an installation state of a monitoring system using a wireless interlocking type house guard according to the second invention of the present application for a house. In the example of FIG. 7, a wireless dwelling device (for dwelling) that detects and alerts to a fire in each of the warning areas of the living room, kitchen, children's room, master bedroom, and staircase provided in the house 25 . Fire alarms 100-1 to 100-6 are installed.

  The appearance of the home alarm devices 100-1 to 100-6 is basically the same as that of the home alarm device 10 according to the first invention of this application shown in FIG.

The home alarm devices 100-1 to 100-6 have a function of transmitting and receiving event signals to each other wirelessly, and monitor each corresponding monitoring area in each place of the house. Here, six units monitor the fire of the whole house. Is going. If a fire has occurred in the kitchen of the house 25, the home alarm device 100-1 detects the fire and starts an alarm.

  When the home alarm device 100-1 issues a warning, the home alarm device 100-1 functions as an interlock source, and an event signal indicating a fire is sent to the other home alarm devices 100-2 to 100-6 as the interlock destinations ( (Fire event signal) is transmitted wirelessly. When the other home alarm devices 100-2 to 100-6 have effectively received an event signal indicating the occurrence of a fire from the home alarm device 100-1 of the interlocking source, an alarm operation as an interlocking destination by an alarm sound and an alarm display I do.

  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. Further, the event signal transmitted from the home alarm device 100-1 to 100-6 includes, for example, a transmission source code as identification information indicating the source home alarm device. In addition, the residence guard 1000 that has received the event signal effectively performs relay transmission of the event signal as necessary.

  The alarm operation of the home alarm 100-1 that is the source of the linkage is, for example, a sweep sound such as “It is a fire. An alarm display is made to shine with a display pattern corresponding to the change state of the output sound pressure of the fire alarm sound indicating the origin.

  On the other hand, the interlocking destination residence alarm devices 100-2 to 100-6 output a sweep sound such as “Another alarm device has been activated” and a disaster warning sound indicating the interlocking destination of the predetermined pattern by the message. At the same time, the LED 22 is used to display an alarm that is lit in a display pattern corresponding to the change state of the output sound pressure of the fire alarm sound indicating the interlocking destination.

  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 home alarm devices 100-1 to 100-6 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 residence police 100-1 that is the interlocking source, the alarms (alarm sound output and / or alarm display output) of all the residence policers 100-1 to 100-6 ), And when the alarm stop operation is performed in any of the interlocking devices 100-2 to 100-6, the alarm of the interlocking device 100-1 does not stop, The alarms of the interlocked residence alarm devices 100-2 to 100-6 are stopped. In addition, in the following description, when calling the housing alarms 100-1 to 100-6 without distinguishing, it is called the housing alarm 100.

  In addition, the home alarm 100 automatically performs a monitoring process for detecting a low battery failure from a drop in the voltage supplied from the battery power as a built-in test in the background every predetermined period. A low battery fault alarm that indicates the source (failure source) is output, and an event signal (low battery fault event signal) that indicates a low battery fault is sent to the other housing alarms, indicating a linkage destination (failure destination) A fault alarm is output.

  The low battery failure alarm indicating the link source, for example, continuously outputs “battery exhausted” multiple times from the speaker of the home alarm device 100 and turns on the LED, for example. 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 100 a plurality of times and blinks the LED, for example.

  In addition, when the alarm 100 is operated as a check switch in the normal state, the home alarm 100 detects a low battery failure by a monitoring process automatically executed in the background as a built-in test. As an alarm, for example, “Pattern is out of battery” is output continuously several times and the LED is turned on, for example, and an event signal indicating a low battery failure (low battery failure event signal) is transmitted to other housing alarms. As a low battery failure alarm indicating the destination (failure destination), for example, “a separate alarm device is out of battery” is continuously output a plurality of times and the LED is blinked, for example. On the other hand, if a low battery failure is not detected (normal), the fire alarm sound “Woo Woo fire alarm has been activated” should be checked at a lower volume than the failure alarm sound to check the speaker operation. Output once.

  Moreover, the house alarm device 100 automatically executes a monitoring process for detecting a sensor failure as a built-in test in the background at predetermined intervals, and outputs a sensor failure alarm indicating a linkage source (failure source) when a sensor failure is detected. At the same time, an event signal (sensor failure event signal) indicating a sensor failure is transmitted to another residential alarm, and a sensor failure alarm indicating a linkage destination (failure destination) is output. The sensor failure detected by the home alarm 100 includes a sensor, a detection circuit, a sensitivity abnormality due to contamination, and the like.

  In addition, when the home alarm device 100 detects an operation of an alarm stop switch that functions as a check switch in a normal state, when a sensor failure is detected by a monitoring process automatically executed in the background as a built-in test, For example, “pick failure” is output continuously several times as a failure alarm sound indicating the interlock source (failure source), and the LED is lit, for example, and then a “pick failure” audio output is output at regular intervals by the periodic notification timer. And the display by turning on the LED is repeated a plurality of times.

  In addition, when the home alarm device 100 detects a sensor failure, it sends an event signal (sensor failure event signal) indicating the sensor failure to another home alarm device, for example, an alarm such as “a separate alarm device is faulty”. A sound is output and a display different from the interlock source, for example, blinking is performed.

  In addition, when the home alarm device 100 detects an operation of an alarm stop switch that functions as an inspection switch in a normal state, when a sensor failure is detected by a monitoring process automatically executed in the background as a built-in test, As an alarm, for example, “Pattern is out of battery” is output continuously several times and the LED is turned on, for example, and an event signal (sensor failure event signal) indicating a sensor failure is sent to other residential alarms at the same time. For example, “a separate alarm device is faulty” is continuously output a plurality of times and the LED is blinked, for example.

  On the other hand, if a sensor failure is not detected (normal), a fire alarm sound “Woooo is a fire” is output once at a volume lower than the sensor failure sound to check the speaker operation. Also in this case, the LED is inspected and driven by a display pattern corresponding to the change state of the output sound pressure of the alarm sound for speaker inspection output from the speaker 36, such as “Peepy Fire is Fire”. It is tuned to the sound.

  By synchronizing the lighting method of the LED with the alarm sound for speaker inspection during such an inspection operation, the user has an opportunity to learn the alarm output in which the sound and the light are synchronized through the inspection operation. Therefore, in the unlikely event that a fire is detected with a failure that does not produce sound from the speakers, it can be expected that the alarm content such as “Peep fire is fire” will be inferred from the way the LED shines.

  FIG. 8 is a block diagram showing an embodiment of a wireless liaison guard according to the second invention of the present application. 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.

  Moreover, in FIG. 8, although the residence guard is shown about the residence guard 100-1 installed in the kitchen, it becomes the same structure also about the other residence guards 100-2 to 100-6.

  The home guard 100-1 is provided with a processor 128 known as a one-chip CPU. For the processor 128, a wireless communication unit 130 including an antenna 131, a memory 132, a sensor unit 134, a notification unit 136, and an operation unit 138. And a battery power supply 140 is provided.

  The wireless communication unit 130 is provided with a transmission circuit 142 and a reception circuit 144 so that event signals can be transmitted and received wirelessly between the other residential alarm devices 100-2 to 100-6. As the wireless communication unit 130, in Japan, for example, STD-30 (a wireless equipment standard for a low power security system wireless station) or STD-T67 known as a standard for a specific low power wireless station in the 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 130 is used outside Japan, the wireless communication unit 130 has contents compliant with the standard of the assigned wireless station in that region.

  The antenna 131, the transmission circuit 142, and the transmission processing unit 160 are collectively referred to as a transmission unit, and the antenna 131, the reception circuit 144, and the reception processing unit 162 are collectively referred to as a transmission unit.

  The memory 132 includes a serial number 148, which is a serial number indicating the order of the event signals, a transmission source code 150 serving as housing alarm identification information for identifying each house alarm, and a housing alarm installed in a house as shown in FIG. The group code | symbol 152 for comprising the interlocking | linkage group which performs an interlocking alarm by 100-1 to 100-6 is stored.

  The serial number 148 is a code that is automatically generated and updated (e.g., incremented) every time an event signal is transmitted, and relays the event signal between alarm devices, particularly in wireless communication. This is for managing processing and the like, but since it is not directly related to the present invention, detailed description thereof is omitted.

  The source code 150 is, for example, a 26-bit multi-bit code code so that it does not overlap with any of the domestic alarms provided in the country. For example, the serial number of the local alarm or the earthquake early warning device is used. We are using.

  Re-relay can be permitted or prohibited by using the serial number 148 or the transmission source code 150, 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 determine whether transmission is possible or not. In addition, relay transmission permission and prohibition can be set for each event content indicated by the event signal.

  The group code 152 is a code that is set in common to a plurality of residential alarms that constitute the interlocking group, and the group code included in the event signal received by the wireless communication unit 130 is the group code 152 registered in the memory 132. 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 152 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 the other house alarm belongs are the same. Anything is fine. Registration of the group code 152 is performed by an appropriate method such as setting of an external switch or automatic registration using a communication function before shipping or before starting operation.

  Further, the memory 132 stores a failure detected by the low battery failure flag 180 or the sensor failure flag 182 as a result of failure detection processing by automatic inspection that is automatically executed in the background periodically as a build-in test. . In addition, a periodic notification timer 186 that is used to output a periodic failure alarm after detecting a low battery failure or a sensor failure is provided. Note that the periodic notification timer 186 may be arranged on a program executed by the processor 128 without being arranged in the memory 132.

  Furthermore, in this embodiment, an alarm sound failure flag 184 is stored in the memory 132 as a failure detection result by failure monitoring processing (automatic inspection) that is automatically executed in the background periodically as a build-in test. Reference numeral 184 denotes a failure in the speaker system in which no sound is output from the speaker 156 provided in the notification unit 136.

  The sensor unit 134 is provided with a smoke detector 116 that detects smoke and outputs a detection signal corresponding to the smoke concentration. As described above, instead of the smoke detector unit 116, the sensor unit 134 detects elements that detect the 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 notification unit 136 is provided with a speaker 156 that is an acoustic output device that outputs an alarm sound and the like, and an LED 122 that displays an alarm. The speaker 156 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 122 displays an abnormal alarm such as a fire by a display pattern corresponding to the change state of the output sound pressure of the fire alarm sound, and other information is displayed by lighting, blinking or blinking. Instead of the LED 122 , 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 138 is provided with an alarm stop switch 120. The alarm stop switch 120 functions as an alarm stop switch only when the alarm unit 136 outputs a fire or failure alarm sound from the notification unit 136 or when an alarm display is performed by the LED 122.

  For example, when the alarm stop switch 120 is operated during the alarm indicating the interlock source, the alarm sound and the alarm display are stopped, and when the alarm stop switch 120 is operated during the alarm indicating the interlock destination, the alarm sound and the alarm display are Stopped. On the other hand, when the alarm stop switch 120 is operated during an alarm indicating the linkage destination, an alarm stop process is performed in which the alarm sound is stopped and the alarm display is stopped or stopped after a predetermined time from the alarm sound stop.

  On the other hand, the alarm stop switch 120 functions as an inspection switch in a normal state in which the fire alarm or the failure alarm indicating the interlock source or the interlock destination is not performed, and when the alarm stop switch 120 is operated in this state, the inspection operation is detected, It is automatically executed in the background as a built-in test, and it is detected whether or not the low battery failure flag 180 or the sensor failure flag 182 as an automatic inspection result is stored in the memory 132. If the failure flag is stored, the notification unit 136 A failure alarm such as a voice message indicating the corresponding failure content is output from the speaker 156.

When the failure flag is not stored in the memory 132 , the inspection result is normal. Therefore, the same alarm sound for speaker inspection as the fire alarm sound for inspecting the speaker 156 is set at a volume lower than the failure alarm sound. In addition, the display pattern is inspected and displayed according to the change state of the output sound pressure of the alarm sound for speaker inspection.

  In addition, the inspection is not performed in the background as a built-in test, and when the alarm stop switch 120 is operated in a normal state (when an inspection instruction operation is detected), a predetermined inspection including battery failure detection and sensor failure detection is performed. You may make it alert | report a result by implementing operation | movement.

  In addition, when the alarm stop switch 120 is operated during a fault alarm, a predetermined check operation including battery fault detection and sensor fault detection is performed, and the result is notified, and then the fault alarm stop process is performed. Also good. 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, if 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 be shifted to the failure stop (recovery) process.

  The battery power supply 140 uses, for example, a lithium battery or an alkaline battery having a predetermined number of cells, supplies power to each part as necessary, and the battery capacity of the wireless communication unit 130 in the residential alarm device 100-1 For example, the battery life of 10 years is guaranteed by reducing the power consumption of the entire circuit unit.

  The processor 128 is provided with functions of an event detection unit 158, a transmission processing unit 160, a reception processing unit 162, a monitoring processing unit 164, and an inspection processing unit 170 as functions realized by executing the program. The monitoring processing unit 164 includes Functions of an alarm sound control unit 166 and an alarm display control unit 168 are provided.

  The event detection unit 158 is configured to detect the presence of a fire based on the detection signal output of the sensor unit 134, the presence or absence of an alarm stop instruction input by the operation unit 138, the presence or absence of an inspection instruction, Detects events such as fire recovery, sensor failure, low battery failure, alarm sound failure, etc. The event detection unit 158 also 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 100-2 to 100-6 via the reception circuit 144 and the reception processing unit 162, and the contents of the event. Is detected.

  The transmission processing unit 160 detects the fire from the detection signal output of the sensor unit 134 by the event detection unit 158, stops the alarm by the operation unit 138, and recovers the fire in which the detection signal output of the sensor unit 134 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 131 to the interlocking house policing device via the transmission circuit 142 of the wireless communication unit 130.

  The reception processing unit 162 receives and decodes the event signals from the other residential alarm devices 100-2 to 100-6 from the antenna 131 via the reception circuit 144 of the wireless communication unit 130.

  In addition, the reception processing unit 162 monitors whether or not an acknowledgment signal (hereinafter referred to as “ACK signal”) indicating that the interlocking signal has been normally received from the other residential alarm devices 10-2 to 10-6 is effectively received. doing.

  Of the other home alarm devices 10-2 to 10-6, when a home alarm device in which the ACK signal is not received (not responded) is detected, the transmission processing unit 160 performs the response to the responded home alarm device in which the ACK signal has been received. The relay request interlocking signal is transmitted, and the relay request interlocking signal is relayed and transmitted to the home alarm device that has not received the AKC signal (relay instruction destination home alarm device) that has received the relay request interlocking signal. The other home alarm device that has not relayed the AKC signal that has received the relay request interlocking signal transmits an ACK signal in response to the relay request, and this ACK signal is relayed by the relay instruction destination home alarm device and then the interlocking source home alarm device. 10-1 is received.

When the event detection unit 158 detects a fire as an abnormality of the event, the monitoring processing unit 164 receives a signal indicating that and outputs an alarm sound indicating a source of synchronization of a predetermined pattern including a sweep sound and a message from the speaker 156. At the same time, the LED 122 is driven to emit light with a display pattern corresponding to the change state of the output sound pressure of the alarm sound indicating the interlock source, and the alarm display indicating the interlock source is performed. Are sent to the home alarm devices 100-2 to 100-6.

Specifically, when the event detection unit 158 detects a fire based on the smoke detection signal of the smoke detection unit 116 provided in the sensor unit 134, the monitoring processing unit 164 receives a signal indicating that from the event detection unit 158. Based on this, the alarm sound control unit 166 controls the alarm unit 136 to repeatedly output an alarm sound indicating the link source from the speaker 156, for example, a voice message of “Woo Woo is a fire” and alarm display control. The unit 168 drives the LED 122 to emit light according to the display pattern corresponding to the change state of the output sound pressure of the alarm sound shown in FIG. 3B or FIG. Furthermore, the transmission processing unit 160 and from the event signal indicating the fire through the transmitting circuit 142 antenna 131 other home alarm 100- To be transmitted to the ～100-6.

In addition, the monitoring processing unit 164 detects when the event detection unit 158 detects that the fire event signal has been effectively received from any of the other home alarm devices 100-2 to 100-6 by the reception circuit 144 of the wireless communication unit 130. The alarm sound control unit 166 receives a signal to that effect, and the alarm sound (notification sound) indicating the interlocking destination of the predetermined pattern consisting of the sweep sound and the message from the speaker 156 of the notification unit 136, for example, It causes repeatedly output has activated ", shown by the warning display control unit 168, the interlocking destination the interlocking destination glowing as to drive the LED122 accordance with the display pattern corresponding to such changes in the status of the output sound pressure of alarm sound indicating alarm Make a display.

Further, the monitoring processing unit 164 detects the operation of the alarm stop switch 120 while the event detection unit 158 outputs the fire alarm sound indicating the interlock source or the fire alarm sound indicating the interlock destination, or other residential alarm device 100- 2) When receiving an event signal indicating an alarm stop or an apparatus event signal from any one of 100-6, a signal indicating that is received from the event detection unit 158, and a voice message from the speaker 156 and an alarm display on the LED 122 Stops the output of the fire alarm. At this time, the alarm display by the LED 122 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.

  The event detection unit 158 automatically executes a low battery failure monitoring process in a background as a build-in test at predetermined intervals, and directly via a voltage detection circuit (not shown) at a predetermined measurement time interval, for example, T11 = 4 time intervals. Indirectly or indirectly, the power supply voltage supplied from the battery power supply 140 is read by A / D conversion and compared with a predetermined threshold voltage. When the voltage is lower than this threshold voltage, the detection of a low battery failure is tentatively determined. A low battery failure is detected (determined) when the failure tentative determination continues for a predetermined number of times, and a low battery failure flag 180 is set and stored in the memory 132.

  In addition, the event detection unit 158 automatically executes sensor failure monitoring processing in a background as a built-in test every predetermined cycle, and from the smoke detection unit 116 of the sensor unit 134 at a predetermined measurement time interval, for example, T12 = 1 second interval. The smoke detection signal to be output is read by A / D conversion and held in the buffer area of the memory 132. For example, detection of 100 minutes held in the buffer area of the memory 132 every predetermined time interval T13 = 100 minutes An average value of the data is obtained, and when the average value falls below a predetermined reference level (referred to as the zero point level), it is detected that the output of the sensor unit 134 is faulty, and a sensor fault flag 182 is set and the memory 132 is set. Remember me.

  The reason why the 100-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 116, 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 134 , a sensor failure can be similarly detected by various processes. In addition, 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 processing similar to that for a sensor failure is performed after detection.

  The event detection unit 158 automatically executes alarm sound failure detection processing in a background as a built-in test every predetermined cycle, and the speaker 156 is connected at a predetermined measurement time interval, for example, the same T11 = 4 hour interval as low battery failure detection. A voice output system (not shown) including the above is tested to detect the presence or absence of a failure. For the test of the audio output system, for example, a DC test signal that does not produce sound is output to the speaker 156, the detected voltage of the speaker driving current is read by A / D conversion, and compared with a predetermined threshold voltage. Preliminary detection (provisional determination) of an alarm sound failure due to disconnection of the speaker output line at the time of detection, and further (predetermined) an alarm sound failure when the preliminary detection (provisional determination) of the alarm sound failure continues for a predetermined number of times, The alarm sound failure flag 184 is set and stored in the memory 132.

  When an alarm sound failure without sound is detected from the speaker 156 by the event detection unit 158 and the alarm sound failure flag 184 is stored in the memory 132, the display control unit 168 provided in the monitoring processing unit 164 is the event detection unit 158. When detecting a fire or valid reception of an event signal indicating a fire from another house alarm and receiving a signal indicating that, an alarm indicating an interlocking source or interlocking destination by increasing the drive current flowing to the LED 122 The display pattern corresponding to the change state of the sound output sound pressure, etc., increases the drive current to increase the display brightness, thereby strengthening the light from the LED 122 even in the situation where no fire alarm sound is emitted from the speaker 156 In this way, the fire alarm is transmitted to the user more reliably.

  Here, when the alarm sound failure is determined, the increase in the drive current that flows to the LED 122 is within a range that does not exceed the drive current for alarm sound output that flows to the speaker 156, and the speaker 156 is functioning normally. It is assumed that the power consumption of the battery power supply 140 is equivalent or less.

  In addition, failure detection is not performed in the background as a built-in test, but when the operation of the alarm stop switch 120 is detected in a normal state (when an inspection instruction operation is detected), battery failure detection, sensor failure detection, and alarm sound are detected. A predetermined failure detection operation (inspection operation) including failure detection may be performed to notify the result.

  In addition, when the alarm stop switch 120 is operated during a fault alarm, the fault detection operation (inspection operation) including battery fault detection, sensor fault detection, and alarm sound fault detection is performed again, and the fault is reported. An alarm stop process may be performed. 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.

Monitoring processor 164, when detecting low battery failure event detecting unit 158 receives a signal indicating to set the low battery fault flag 180 in the memory 132 and stored, the notification unit by the alarm sound control section 166 As a low battery failure alarm sound indicating the link source (failure source) 136, for example, “battery is exhausted” is continuously output a plurality of times, and the LED 122 is lit by the alarm display control unit 168, for example. After that, the periodic notification timer 186 of the memory 132 is activated, and a sound output “battery dead” and a display such as blinking of the LED 122 are repeatedly performed every predetermined time based on the low battery failure flag stored in the memory 132. Repeat the process to be performed.

  At the same time, the monitoring processing unit 164 transmits a low battery failure event signal to the other residential alarm devices 100-2 to 100-6, thereby using the low battery failure alarm indicating the interlocking destination as an alarm sound. Is running out of battery "and a blinking display different from the interlock source is displayed.

The monitoring processor 164 detects the determination of sensor failure event detecting unit 158, when receiving the signal indicating to set the sensor failure flag 182 in the memory 132 and stored, the alarm sound control section 166 Thus, for example, “pick failure” is continuously output from the speaker 156 of the notification unit 136 as a sensor failure alarm sound indicating the link source (failure source) a plurality of times, and the alarm display control unit 168 simultaneously turns on the LED 122, for example. After that, the periodic notification timer 186 of the memory 132 is started, and the process of performing the sound output of “pick failure” and the display by the LED 122 a plurality of times every predetermined time based on the sensor failure flag 182 stored in the memory 132 is repeated. . At the same time, the monitoring processing unit 164 transmits a sensor failure event signal to the other residential alarm devices 100-2 to 100-6, thereby generating a low battery failure alarm indicating the linkage destination 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 170 detects an inspection instruction operation (inspection instruction input) by the operation of the alarm stop switch 120 that functions as an inspection switch in the normal state by the event detection unit 158, and the low battery failure flag 180 is stored in the memory 132. If it is detected, the alarm sound control unit 166 continuously outputs, for example, “Battery is dead” several times, and the alarm display control unit 168 simultaneously lights the LED 122, for example, and at the same time, the low battery failure event By sending a signal to the other housing alarm devices 100-2 to 100-6, the low battery failure alarm indicating the interlocking destination is output as an alarm sound and “Picking another alarm device is out of battery” is output. Different blinking display is used.

  The inspection processing unit 170 detects an inspection instruction operation (inspection instruction input) by the operation of the alarm stop switch 120 by the event detection unit 158, and further detects that the sensor failure flag 182 is stored in the memory 132. For example, the alarm sound control unit 166 continuously outputs, for example, “pit failure” a plurality of times, and at the same time, the alarm display control unit 168 turns on the LED 122, for example. By transmitting to the alarm devices 100-2 to 100-6, the low battery failure alarm indicating the interlocking destination is output as an alarm sound and “Picting alarm device is out of battery” is output, and the flashing display is different from the interlocking source. To do.

  Thus, when the operation of the alarm stop switch 120 is detected 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.

The inspection processing unit 170 detects an inspection instruction operation (inspection instruction input) by operating the alarm stop switch 120 by the event detection unit 158 and further detects that the alarm sound failure flag 184 is stored in the memory 132. Since there is no sound from the speaker 156 , the alarm display control unit 168 turns on the LED 122, for example, and transmits an alarm sound failure event signal to the other residential alarm devices 100-2 to 100-6. The low battery failure alarm that indicates the previous point is output as a warning sound, and a separate alarm is out of battery. For this reason, it is possible to know the contents of the alarm sound failure without sound from the speaker 156 from the alarm sound of the interlocking home alarm devices 100-2 to 100-6.

In addition, when the event detection unit 158 detects an inspection instruction operation (inspection instruction input) by operating the alarm stop switch 120 that functions as an inspection switch in a normal state, the inspection processing unit 170 stores a low battery failure flag 180 and a sensor in the memory 132. If the failure flag 182 and the alarm sound failure flag 184 are not stored, it is determined that the alarm is normal, and in this case, the speaker check for confirming that the alarm sound is normally output from the speaker 156 provided in the notification unit 136 For this reason, “Wu Wu fire alarm should be confirmed” is output once at a volume lower than the fault alarm sound as an alarm sound for speaker inspection having the same content as the fire alarm sound.

  At the same time, the inspection processing unit 170 drives the LED 122 so that the alarm display control unit 168 shines in the display pattern shown in FIG. 3B or FIG. 3C corresponding to the change state of the output sound pressure of the alarm sound for speaker inspection. As a result, the user is unconsciously trained to learn fire alarms using sound and light.

  When the event detection unit 158 detects an inspection instruction operation (inspection instruction input) by operating the alarm stop switch 120 that functions as an inspection switch in a normal state, the inspection processing unit 170 instructs the event detection unit 158 to perform a low Execute the battery failure and sensor failure detection process (automatic check) again. If a failure is detected, a failure alarm is output. If normal is detected, an alarm sound for speaker inspection is output and the output sound pressure of the alarm sound is reduced. You may make it perform the alarm display corresponding to a change condition. Thereby, the latest inspection result can be notified.

  FIG. 9 is an explanatory diagram schematically showing an event signal format used for the linked alarm in the present embodiment. In FIG. 9, the event signal 146 includes a serial number 148, a transmission source code 150, a group code 152, and an event code 154.

  The serial number 148 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 148 is generated asynchronously in each of the residential alarms. The serial number 148 is used to manage event signal relay processing, etc., mainly in the radio communication between the residential alarms 100, but is not directly related to the present invention, and thus detailed description thereof is omitted.

  The transmission source code 150 is, for example, a 26-bit code used as house alarm identification information, and uses, for example, a house alarm serial number. The group code 152 is, for example, an 8-bit code, and the same group code is set, for example, for the residential alarm devices 100-1 to 100-6 in FIG.

  As the group code 152, 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 sender 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 154 is a code representing the event content such as a fire, gas leak (for example, a gas leak alarm or a residential alarm having a gas leak detection function), and in this embodiment, a 4-bit code is used. For example, 0001 = fire 0010 = gas leak 0011 = alarm stop (fire alarm stop, gas leak alarm stop, fault alarm stop)
0100 = recovery (fire recovery, gas leak recovery, failure recovery)
0101 = Sensor failure 0110 = Low battery failure 0111 = Alarm sound failure. Here, 0000 is used for periodic notification, for example, without event detection.

By increasing the number of bits of the event code 154 to 5 bits or 6 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-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 of different abnormality types to be detected can be mixed in the same group.

  10 to 13 are flowcharts showing an example of the monitoring process in the residential alarm device 100-1 of FIG. In FIG. 10, when the power supply by the battery power supply 140 of the home guard 100-1 is started, various settings including the presence / absence of initialization, self-diagnosis, and prohibition mode setting are executed in step S31. If not, the process proceeds to step S32, and the presence or absence of a fire is detected.

  When the smoke detection signal output from the sensor unit 134 exceeds a predetermined fire level, the presence of a fire is detected in step S32, and the process proceeds to step S33, where a serial number and a transmission that identifies the fire alarm detecting the fire are transmitted. An event signal including an original code, a group code, and an event code indicating a fire is wirelessly transmitted to another residential alarm.

  Subsequently, the process proceeds to step S34. At this time, it is determined whether or not an alarm sound failure is detected by storing the alarm sound failure flag 184 with reference to the memory 132, and if the alarm sound failure is detected, the process proceeds to step S35. Then, the setting is made to increase the drive current flowing through the LED 122. Of course, if the storage of the alarm sound failure is not detected, the process of step S35 is skipped.

  Subsequently, in step S36, the alarm sound indicating the interlocking source of the predetermined pattern consisting of the sweep sound and the message is output from the speaker 156 of the notification unit 136, and the display corresponding to the change state of the output sound pressure of the alarm sound indicating the interlocking source, etc. The LED 122 is driven to display so as to shine in a pattern, and a fire alarm indicating the interlocking source is output.

  Subsequently, in step S37, the presence or absence of a fire recovery in which the smoke detection signal from the sensor unit 134 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 S38. After transmitting the event signal including the code and the event code indicating the fire recovery to the other home alarm device, in step S39, the fire indicating the interlocking source by the alarm sound from the speaker 156 and the alarm display by the alarm sound corresponding pattern display of the LED 122 Stop the alarm. The alarm display by the LED 122 may be turned off after a predetermined time has elapsed.

Subsequently, at step 40, the presence or absence of an alarm stop instruction operation of the alarm stop switch 120 during the alarm is detected, and when the switch operation is detected, the process proceeds to step S41, where the serial number, source code, group code, alarm stop An event signal including an event code indicating the alarm code is transmitted to another home alarm device, the process proceeds to step S42, the alarm sound output indicating the interlock source from the speaker 156 is stopped, and the alarm display by the alarm sound corresponding pattern display of the LED 122 is displayed. Stop. The LED 122 may be stopped after a predetermined time has elapsed.

  Then, it progresses to step S43 of FIG. 11, and the presence or absence of the effective reception of the event signal which shows the fire transmitted or relay-transmitted from the other residence police is detected. If it is detected that an event signal indicating a fire from another house alarm is received, the process proceeds to step S44 and the memory 132 is referred to, and it is determined whether or not an alarm sound failure is detected by storing the alarm sound failure flag 184. If an alarm sound failure is detected, the process proceeds to step S45, and a setting is made to increase the drive current flowing through the LED 122. Of course, if no alarm sound failure is detected, the process of step S45 is skipped.

  Subsequently, the process proceeds to step S46, where an alarm sound indicating the interlock destination of the predetermined pattern consisting of the sweep sound and the message is output from the speaker 156, and the display pattern corresponding to the change state of the output sound pressure of the alarm sound indicating the interlock destination is used. An alarm is displayed by driving the LED 122.

  Next, in step S47, the presence / absence of effective reception of an event signal indicating fire recovery transmitted or relayed from another resident alarm is detected. Then, the alarm display by the alarm sound output from the speaker 156 and the alarm sound correspondence pattern of the LED 122, which is performed as the alarm of the interlocking destination, is stopped.

  Next, in step S49, the presence or absence of effective reception of an event signal indicating an alarm stop transmitted from another home alarm device or relay transmission is detected. The process proceeds to step S51 to detect the presence or absence of an alarm. When the alarm is detected, the process proceeds to step S51 where the alarm sound output as the interlocking destination is stopped and the alarm display is also stopped.

  Subsequently, the process proceeds to step S52 in FIG. 12, where it is detected whether or not there is a low battery failure. When it is detected that there is a low battery failure, the process proceeds to step S53 where the low battery failure flag 180 is set in the memory 132 and stored. Start up.

  Subsequently, in step S54, a low battery failure alarm sound indicating a failure source is output and an alarm display is performed. Then, the process proceeds to step S55, and an event signal including a serial number, a transmission source code, a group code, and an event code indicating a low battery failure is obtained. Is sent to other mortgages to make a fault alarm as a link destination.

  In step S56, the presence or absence of a sensor failure is detected. If it is detected that the sensor failure has occurred, the flow advances to step S57 to set and store the sensor failure flag 182 in the memory 132 and start the periodic notification timer 186.

  Subsequently, in step S58, the sensor failure alarm sound indicating the failure source is output and the alarm display is performed. Then, the process proceeds to step S59, and the event signal including the serial number, the transmission source code, the group code, and the event code indicating the sensor failure is added. Send it to the home alarm.

  Subsequently, the process proceeds to step S60, where the presence or absence of an alarm sound failure is detected. When the presence of the alarm sound failure is detected, the process proceeds to step S61 where the alarm sound failure flag 184 is set and stored in the memory 132 and the periodic notification timer 186 is started. .

  Subsequently, in step S62, an alarm sound failure alarm indicating the source of the failure is performed. At this time, no sound is output from the speaker 156, so that the failure display is performed only by turning on the LED 122, for example. Here, in the case of alarm sound failure detection, since the drive current flowing through the LED 122 is increased, strong light is emitted from the LED 122.

  Subsequently, the process proceeds to step S63, where an event signal including an event code indicating a serial number, a transmission source code, a group code, and an alarm sound failure is transmitted to another house alarm device, and the other alarm device indicates an interlock destination. Alarm display by sound output and flashing.

  Subsequently, the process proceeds to step S64 in FIG. 13, and it is detected whether or not the low battery failure flag 180, the sensor failure flag 182 or the alarm sound failure flag 184 is stored in the memory 132, and any of the failure flags is stored. If it is detected, the process proceeds to step S65, and it is detected whether the regular ringing timer 186 started in step S53, S57 or S61 has reached a regular ringing timing, and if the regular ringing timing is detected, the process proceeds to step S66, where a low battery failure occurs. If the flag 180 is stored, a low battery failure alarm is output. If the sensor failure flag 182 is stored, a sensor failure alarm is output. If the alarm sound failure flag 184 is stored, an alarm sound failure alarm is output. Let At this time, if the LED 122 is lit with strong light and no sound is output from the speaker 156, it is understood that the alarm sound is faulty.

  Subsequently, the process proceeds to step S67, where an event signal including an event code indicating a serial number, a transmission source code, a group code, a low battery failure, a sensor failure, or an alarm sound failure is transmitted to another residential alarm and a failure as a linkage destination. Make an alarm.

  Subsequently, the process proceeds to step S68, where the presence or absence of an inspection operation by the alarm stop switch 120 functioning as an inspection switch in the normal state is detected. When the presence of the inspection operation is detected, the process proceeds to step S69, and the low battery failure flag 180 and the sensor failure flag are 182 or when the alarm sound failure flag 184 is not stored, it is detected that no failure has been detected (normal), and the process proceeds to step S70, and the fire alarm sound indicating the interlocking source from the speaker 156 is used as the alarm sound for speaker inspection from the failure alarm sound. While outputting at a low volume once, the LED 122 is driven to illuminate according to a display pattern corresponding to the change state of the output sound pressure of the alarm sound for speaker inspection and the inspection display is performed.

On the other hand, if the low battery fault flag 180 in the memory 132, the sensor fault flag 182 or alarm sound fault flag 184 is stored, the process proceeds to step S71 to detect the presence of failure, low battery failure or sensor failure from the speaker 156 A failure alarm sound including a message indicating the above is output and the LED 122 is blinked, for example. When the alarm sound failure flag 184 is stored in the memory 132, the failure alarm sound cannot be output from the speaker 156. In this case, for example, the LED 122 is turned on to notify the failure.

  Subsequently, the process proceeds to step S72, where an event signal including an event code indicating a serial number, a transmission source code, a group code, a low battery failure, a sensor failure or an alarm sound failure is transmitted to another house alarm, and the failure as a linkage destination Make an alarm.

  In the above embodiment, when an abnormality such as a fire is detected, an alarm is displayed by driving the LED with a display pattern corresponding to the change state of the output sound pressure of the abnormality alarm sound including a message. However, when a notification sound including a message is output even in a case other than a fire, for example, for a failure notification sound, the LED is driven by a display pattern corresponding to the change state of the output sound pressure of the notification sound. It may be displayed.
