Description

The present invention relates to an alarm device that outputs an alarm sound and displays an alarm by detecting an abnormality or failure such as a fire.

  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”.

  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.

  In addition to automatic inspections that periodically determine the presence or absence of low battery failures, conventional residential alarms detect sensor failures such as sensor and detection circuit failure, voice notification circuit failure, and abnormal sensitivity. The automatic inspection is periodically executed and stored in the memory. When the inspection is instructed by operating the alarm stop switch in the normal state, the inspection result stored in the memory is notified.

If there is no failure, the inspection result is output once at a low volume to check the speaker, for example, the same sound as the fire alarm sound, “Woo Woo fire alarm has been activated”. 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.

  According to the alarm device of the present invention, an alarm sound failure such as an alarm sound loss state in which an alarm sound is not output due to a decrease in alarm sound performance from an acoustic transducer such as a speaker or a buzzer or an output line disconnection occurs. When an abnormality such as a fire is detected, as an alarm sound substitution process that substitutes for an alarm output by an alarm sound, for example, the drive current passed through an alarm indicator such as an LED is increased to increase the brightness of the alarm display so that it shines strongly. Or, by performing alternative controls such as driving other indicators provided on the alarm device together with the alarm indicator and illuminating multiple indicators to display the alarm, the alarm function due to the absence of an alarm sound It is possible to suppress the decrease and more reliably notify the user of the occurrence of an abnormality.

  FIG. 1 is an explanatory view showing an appearance of a so-called stand-arrow type home alarm device according to the present invention that is installed and used alone. FIG. 1 (A) is a front view, and FIG. 1 (B) is 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 in the center of the cover 12, and a smoke detector 16 is arranged in the inside, and a fire is detected when smoke due to fire reaches a predetermined concentration as a change in the environment of the warning area Like to do. As the smoke detector 16, for example, a known scattered light smoke detector mechanism can be applied.

A plurality of openings provided in the cover 12 are provided with a smoke detector 16, and an acoustic hole 18 is provided at the lower left side of the smoke detector 16. 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 for instructing notification of the inspection result of the residential alarm 10 from the outside. 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 built-in 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 residential alarm 10 can be fixedly installed on the wall surface or the like 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 if 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 made up of a sweep sound 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. Moreover, LED22 blinks, blinks, or blinks as an alarm display accompanying the fire alarm of the residential alarm 10.

  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 performs a failure detection process (automatic inspection) that determines a low battery failure from a drop in the voltage supplied from the battery power supply as a built-in test in the background at predetermined intervals, and detects a low battery failure. If this happens, a low battery fault 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 performing the voice output and the display by the LED 22 a plurality of times is repeated.

  When the alarm stop switch 20 that functions as an inspection switch is operated in the normal state, the home alarm 10 detects a low battery failure by a failure detection process executed in the background as a built-in test, and updates 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 a low battery failure is not detected normally, in order to check the speaker operation, the same content as the fire alarm sound “Peepy Fire is a fire” is output once at low volume as an alarm sound for speaker check, and the LED For example.

  Moreover, the mortgage alarm device 10 performs a failure detection process (automatic inspection) for determining a sensor failure in the background as a built-in test at predetermined intervals, and outputs a sensor failure alarm when a sensor failure is detected. 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 10 operates the alarm stop switch 20 that functions as an inspection switch in a normal state, the housing alarm 10 determines a sensor failure by a failure detection process executed in the background as a built-in test, and updates and stores it in the memory. For example, a “beep failure” is continuously output from the speaker as a failure alarm sound a plurality of times, and the LED 22 is turned on, for example. The display by lighting is repeated several times.

  On the other hand, in order to check the operation of the speaker when the sensor failure has not been determined normally, “Woooo Fire is a fire” with the same content as the fire alarm sound is output once at a low volume as an alarm sound for speaker inspection, and the LED For example.

  Further, the resident alarm 10 executes a failure detection process (automatic inspection) for detecting an alarm sound failure including an abnormality in which no sound is output from the speaker as a built-in test in the background every predetermined period. Here, the alarm sound failure includes not only the alarm sound output performance loss due to speaker disconnection, but also the alarm sound output performance such as impedance abnormality and drive circuit failure where the current (amplitude and average) flowing through the speaker line is not within the predetermined range. A decline is also included.

  When the alarm device 10 detects an alarm sound failure, the housing alarm device 10 does not output an alarm sound from the speaker, so that the LED 22 is turned on, for example.

  Further, when a fire is detected in a state in which an alarm sound failure such as an abnormality in which no sound is output from the speaker is detected, as an alternative process for the absence of a fire alarm sound, for example, the drive current flowing through the LED 22 is increased to increase the LED 22 The user is strongly informed of the output of the fire alarm.

  This is also the case when a low battery failure or a sensor failure is detected in the state of detecting an alarm sound failure such as an abnormality that makes no sound from the speaker. For example, by increasing the drive current flowing through the LED 22 and making the LED 22 shine strongly, the user is strongly informed of the output of the failure alarm.

  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. A household alarm equipped with a temperature detection element such as a thermistor, a household alarm detecting other physical phenomena associated with fire, an alarm detecting a gas leak other than a fire, an intruder, an earthquake, and other abnormalities (abnormalities) The various alarm devices that detect), and alarm devices formed by combining 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 home alarm device 10 includes 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 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 28 detects elements due to a fire to detect a temperature 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.

Further, the memory 26 is updated when a low battery failure flag 52 or a sensor failure flag 54 detects each failure as a failure detection result by a periodic failure monitoring process (automatic inspection) executed in the background as a built-in test. Is done. In addition, a periodic notification timer 58 used for outputting a periodic failure alarm after detecting a low battery failure or a sensor failure is provided. The periodic notification timer 58 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 56 is stored as a failure detection result by periodic failure monitoring processing (automatic inspection), and the alarm sound failure flag 56 is transmitted from the speaker 36 provided in the notification unit 30. Indicates an alarm sound failure such as an abnormality that does not occur.

  The notification unit 30 is provided with a speaker 36 that is an acoustic transducer 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 held by itself from a voice synthesis circuit unit (not shown) via an amplification unit (not shown). Note that a piezoelectric buzzer or the like may be provided instead of the speaker 36.

  The LED 22 displays an alarm such as a fire or a failure by lighting, blinking or blinking. Furthermore, in this embodiment, when an alarm sound failure such as an abnormality in which no sound is output from the speaker 36 is detected, it is also used for an alarm sound replacement process in which the drive current flowing through the LED 22 is increased to make it shine strongly. .

  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 fire or failure is output from the notification unit 30 by the speaker 36 or when an alarm display is performed by 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 executed in the background and updated and stored in the memory 26 is notified. Notification of the inspection result includes a failure notification and a normal notification. When the normal notification is made, an inspection display is performed by outputting an inspection alarm sound from the speaker 36 and turning on, blinking, or blinking the LED 22.

  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 having a predetermined number of cells, and as a battery capacity, for example, guarantees a battery life of 10 years by reducing the power consumption of the entire circuit unit in the residential alarm 10. Yes.

  The processor 24 is provided with functions of an event detection unit 38, an alarm processing unit 40, and an alarm sound substitution processing unit 50 as functions realized by executing the program.

  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. An event such as a fire recovery for which the state is eliminated, a sensor failure or a low battery failure, an alarm sound failure of the speaker 36, and an alarm sound failure indicating a deterioration or loss of the alarm sound output performance of the speaker 36 is detected.

  When a fire is detected by the event detection unit 38 based on the smoke detection signal of the smoke detection unit 16 provided in the sensor unit 28, the alarm processing unit 40 receives a signal indicating that from the event detection unit 38, Based on this, the alarm unit 30 is controlled to repeatedly output an alarm sound indicating a fire from the speaker 36, for example, a voice message such as “PPP fire is a fire”, and at the same time, the LED 22 is lit, for example, to display an alarm indicating a fire.

  Further, when the alarm processing unit 40 receives the signal indicating that the operation of the alarm stop switch 20 is detected by the event detection unit 38 during the output of the fire alarm sound, the alarm processing unit 40 instructs the notification unit 30 to perform control and the speaker 36. The fire alarm is stopped by the fire alarm sound output from LED and the alarm display of LED22. 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 automatically executes each process of low battery failure detection, sensor failure detection, and alarm sound failure detection as a built-in test periodically in the background, and the result is updated and recorded in the memory 26 each time.

  Specifically, the event detection unit 38 determines the power supply voltage supplied from the battery power supply 35 directly or indirectly via a voltage detection circuit (not shown) at a predetermined measurement time interval, for example, T1 = 4 time intervals. / D conversion is read and compared with a predetermined threshold voltage. When the voltage is lower than this threshold voltage, a low battery failure detection is preliminarily determined (provisional determination), and a low battery failure detection preliminary determination (provisional determination) is continuously performed. When it has continued for a predetermined number of times, it is determined (determined) that there is a low battery failure, and the low battery failure flag 52 is set and updated and stored in the memory 26.

  The event detection unit 38 reads the smoke density detection signal output from the smoke detector 16 of the sensor unit 28 at a predetermined measurement time interval, for example, T2 = 1 second interval by A / D conversion, and stores it in the buffer area of the memory 26. For example, every predetermined time interval T3 = 10 minutes, an average value of 10 minutes of detection data held in the buffer area of the memory 26 is obtained, and this average value is a predetermined reference level (referred to as a zero point level). If it falls below the threshold value, it is determined that the output of the sensor unit 28 has failed, and the sensor failure flag 54 is set, and the memory 26 is updated and stored.

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 detects a warning sound failure by testing a sound output system including the speaker 36 (not shown) at a predetermined measurement time interval, for example, at the same T1 = 4 hour interval as the low battery failure detection. 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. Preliminary determination (provisional determination) of alarm sound failure detection due to disconnection of speaker output line at the time of the alarm, and further determination of alarm sound failure (predetermined) when preliminary determination (provisional determination) of alarm sound failure detection continues for a predetermined number of times Then, the alarm sound failure flag 56 is set and updated and stored in the memory 26.

Further, the event detection unit 38 is not only in a state in which the alarm sound output performance is lost due to the speaker disconnection or the like, but also in the alarm sound output performance due to an abnormal impedance or a drive circuit failure where the current (amplitude or average) flowing through the speaker line is not within a predetermined range. Also, for example, another threshold voltage higher than the threshold voltage used for the determination of disconnection of the speaker output line is set. If the threshold voltage is lower than that, the low alarm sound output performance is determined and the alarm sound failure flag 56 is set. The memory 26 is updated and stored.

  As described above, the detection processing (automatic inspection) of the low battery failure, the sensor failure, and the alarm sound failure in the present embodiment is performed in the background as a built-in test, but the alarm stop switch is not performed in the background but in a normal state. When 20 operations are detected (when an inspection instruction is detected), a predetermined failure detection process including battery failure detection, sensor failure detection, and alarm sound failure may be performed to notify the result.

  In addition, when the operation of the alarm stop switch 20 is detected during a failure alarm, the event detection unit 38 performs again a failure detection operation (check operation) including a battery failure, a sensor failure, and an alarm sound failure. The failure alarm stop process may be performed after informing the user. 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.

When a low battery failure is detected by the event detection unit 38, the alarm processing unit 40 receives a signal to that effect and instructs the notification unit 30 to perform control, and from the speaker 36 of the notification unit 30 as a low battery failure alarm sound. For example, “Battery is out of battery” is continuously output a plurality of times and the LED 22 is lit, for example. Thereafter, the periodic notification timer 58 of the memory 26 is started, and a sound output of “battery dead” and a display by the LED 22 are performed a plurality of times at predetermined intervals based on the low battery failure flag 52 updated and stored in the memory 26. Repeat the process.

In addition , when a sensor failure is detected by the event detection unit 38, the alarm processing unit 40 receives a signal indicating that fact and instructs the notification unit 30 to control, and for example, “sound failure is detected as a sensor failure alarm sound from the speaker 36”. "Is continuously output a plurality of times, and the LED 22 is lit, for example. After that, the periodic notification timer 58 of the memory 26 is started, and the process of outputting a voice “pick failure” and displaying the LED 22 a plurality of times every predetermined time based on the sensor failure flag 54 updated and stored in the memory 26 is repeated. Make it.

  Further, the alarm processing unit 40 receives a signal indicating that an inspection operation (inspection instruction input) due to the operation of the alarm stop switch 20 is detected in the normal state by the event detection unit 38, and the low battery failure flag 52 is stored in the memory 26. Is detected, the notification unit 30 is instructed to perform control, and the speaker 36 continuously outputs, for example, “Battery dead” multiple times and the LED 22 is lit, for example.

  The alarm processing unit 40 receives a signal indicating that an inspection operation (inspection instruction input) due to the operation of the alarm stop switch 20 is detected by the event detection unit 38, and a sensor failure flag 54 is stored in the memory 26. When it is detected, the notification unit 30 is instructed to control the speaker 36 so that, for example, “pick failure” is continuously output a plurality of times, and the LED 22 is lit, for example.

  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, the alarm processing unit 40 receives a signal indicating that an inspection operation (inspection instruction input) due to the operation of the alarm stop switch 20 is detected by the event detection unit 38, and at the same time receives a signal indicating that the low battery failure flag 52 and the sensor failure. When it is detected that the flag 54 is not stored, it is determined to be normal, and in this case, the control is instructed to the notification unit 30 and the speaker 36 confirms that the alarm sound is normally output from the speaker 36. For this reason, “Peepy fire is a fire” having the same content as the fire alarm sound is output once as a speaker inspection alarm sound at a low volume, and the LED 22 is turned on, for example, to display an inspection display.

  The alarm processing unit 40 instructs the event detection unit 38 to perform control when the event detection unit 38 detects an inspection operation (inspection instruction input) by operating the alarm stop switch 20 and receives a signal indicating that. Execute the fault detection process (inspection) for low battery faults and sensor faults again. If a fault is detected, a fault alarm is output. If normal is detected, an alarm sound for speaker check is output and a check is displayed. Also good. Thereby, the latest inspection result can be notified.

  The alarm sound replacement processing unit 50 detects an event when the event detection unit 38 detects an alarm sound failure including an abnormality that makes no sound from the speaker 36 and the alarm sound failure flag 56 is updated and stored in the memory 26. When the unit 38 detects a fire and receives a signal indicating that, for example, there is no sound when the control unit 30 is instructed to output a fire alarm sound from the speaker 36. In order to increase the brightness by increasing the drive current that flows through the LED and to turn on the light from the LED 22 more strongly even in a situation where no fire alarm sound is emitted from the speaker 36, the fire alarm can be transmitted to the user more reliably. To.

  Here, the increase in the drive current that flows to the LED 22 by the alternative processing for the alarm sound failure is within a range that does not exceed, for example, the set average drive current for the alarm sound output that flows to the speaker 36, and the speaker 36 is functioning normally. The degree of wear of the battery power source 35 is equal to or less than the case. In the case of operating with an external power source such as an AC power source instead of a battery power source, such a limitation on the driving current is not necessarily required.

In addition, the alarm sound replacement processing unit 50 is detected by the event detection unit 38 in a state where the event detection unit 38 detects a warning sound failure without sound from the speaker 36 and the alarm sound failure flag 56 is updated and stored in the memory 26. When a battery failure detection or a sensor failure detection is detected and a signal indicating that is received, there is no sound even when an instruction is given to control the notification unit 30 to output a failure alarm sound from the speaker 36. By increasing the drive current that flows through the LED 22 to increase the brightness, for example, even in a situation where a failure alarm sound is not emitted from the speaker 36, the light from the LED 22 is strengthened and turned on, so that the user can be surely notified of the failure. To communicate.

  Also in this case, the increase in the drive current that flows to the LED 22 by the alternative processing for the alarm sound failure is within a range that does not exceed, for example, the set average drive current for alarm sound output that flows to the speaker 36, and the speaker 36 functions normally. It is assumed that the battery power supply 35 is consumed at a level equivalent to or lower than that of the battery.

  3 to 5 are flowcharts showing an example of the monitoring process in the residential alarm 10 of FIG. In FIG. 3, when the power supply by the battery power source 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 and the fire is monitored. doing.

  When the smoke detection signal output from the sensor unit 28 exceeds a predetermined fire level, the presence of fire detection is detected in step S2, and the process proceeds to step S3, where the alarm sound failure flag 56 is stored with reference to the memory 26. If the alarm sound failure flag 56 is not stored, the process proceeds to step S4 to instruct the notification unit 30 to output a fire alarm sound from the speaker 36 by a voice message or buzzer sound. At the same time, a fire alarm is output by, for example, a fire alarm display for turning on the LED 22.

  On the other hand, if the storage of the alarm sound failure flag is detected by referring to the memory 26 in step S3, the process proceeds to step S5, and the drive current passed through the LED 22 as the fire alarm output by the alarm sound substitution process is increased and, for example, lit. By making the LED 22 shine strongly, for example, the deterioration of the fire alarm function due to the absence of an alarm sound is compensated.

  Subsequently, in step S6, it is detected whether or not there is a fire restoration in which the smoke detection signal from the sensor unit 28 is reduced and the fire detection state is resolved. If a fire restoration is detected, an alarm from the speaker 36 is detected in step S7. Fire alarm by sound and 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, the presence or absence of an alarm stop instruction operation of the alarm stop switch 20 during the alarm is detected, and when the switch operation is detected, the process proceeds to step S9 to stop the fire alarm sound output from the speaker 36, The fire alarm display by turning on the LED 22 is turned off. The LED 22 may be turned off after a predetermined time has elapsed.

Subsequently, the process proceeds to step S10 in FIG. 4 , 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 where the low battery failure flag 52 is set in the memory 26 and updated. At the same time, the periodic notification timer 58 is started.

  Subsequently, in step S12, with reference to the memory 26, the presence or absence of the storage of the warning sound failure flag 56 is detected by detection of the warning sound failure, and the presence of the storage of the warning sound failure flag is not detected (when the speaker 36 is normal). In step S13, a fire alarm is output from the speaker 36 of the notification unit 30 by a low battery failure alarm sound such as a voice message or a buzzer sound and a disaster alarm display that drives the LED 22 to turn on.

  On the other hand, if it is detected in step S12 that the alarm sound failure flag is stored, the process proceeds to step S14, where the drive current that is passed through the LED 22 as a low battery alarm output by the alarm sound substitution process is increased to light, for example, and the LED 22 is strongly lit. By making it shine, it compensates for the deterioration of the failure alarm function due to the absence of an alarm sound.

  Subsequently, the process proceeds to step S15, where the presence or absence of a sensor failure is detected. If the presence of a sensor failure is detected, the process proceeds to step S16 where the sensor failure flag 54 is set in the memory 26 and updated and stored, and the periodic notification timer 58 is reached. Start up.

  Subsequently, in step S17, the presence or absence of storage of the alarm sound failure flag 56 is detected with reference to the memory 26. If the presence of storage of the alarm sound failure flag is not detected, the process proceeds to step S18, and the speaker 36 of the notification unit 30 A fault alarm is output by a sensor fault alarm sound such as a voice message or a buzzer sound, and a disaster alarm display that drives the LED 22 to blink, for example.

  On the other hand, if it is detected in step S17 that the alarm sound failure flag has been stored, the process proceeds to step S19, where the drive current that is passed through the LED 22 as a sensor failure alarm output by the alarm sound substitution process is increased and, for example, lit. By making it shine, it compensates for the deterioration of the failure alarm function due to the absence of an alarm sound.

  Subsequently, the process proceeds to step S20, where the presence / absence of an alarm sound failure is detected. When the presence of the alarm sound failure is detected, the process proceeds to step S21 where the alarm sound failure flag 56 is set in the memory 26 to be updated and stored. After the notification timer 58 is activated, the process proceeds to step S22 to display a failure alarm only by blinking of the LED 22.

  Note that the failure alarm indicating the alarm sound failure detection is a failure display only by blinking of the LED 22, for example, because the failure that the failure alarm sound cannot be output from the speaker 36 is detected. The fault alarm function may be strengthened by increasing the drive current to be supplied to the LED and causing it to blink, for example, and causing the LED 22 to shine strongly.

  Subsequently, the process proceeds to step S23 in FIG. 5, and it is detected whether the low battery failure flag 52, the sensor failure flag 54, or the alarm sound failure flag 56 is stored in the memory 26, and the presence of storage of any failure flag is detected. Then, it progresses to step S24, and it is detected whether the regular ringing timer 62 started in step S11, S16 or S21 is the regular ringing timing when a predetermined time has passed.

  When the periodic ringing timing is detected in step S24, the process proceeds to step S25, the presence or absence of storage of the alarm sound failure flag 56 is detected with reference to the memory 26, and if the storage of the alarm sound failure flag is not detected, the process proceeds to step S26. Then, a low battery failure or sensor failure failure warning sound such as a voice message or buzzer sound is output from the speaker 36 of the notification unit 30 and a failure warning is output by a failure warning display in which the LED 22 is driven to blink, for example.

  On the other hand, if it is detected in step S25 that the alarm sound failure flag has been stored, the process proceeds to step S27, where the drive current to be passed through the LED 22 as a sensor failure alarm output by the alarm sound substitution process is increased and blinked, for example, to make the LED 22 stronger. By making it shine, it compensates for the deterioration of the failure alarm function due to the absence of an alarm sound.

  Subsequently, the process proceeds to step S28, 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, and when the presence of the inspection operation is detected, the process proceeds to step S29. If the presence or absence of storage of the flag 56 is detected and the presence of storage of the alarm sound failure flag is not detected, the process proceeds to step S32, and a low battery failure or sensor failure failure alarm from the speaker 36 of the notification unit 30 by a voice message or buzzer sound. A failure alarm is output by a failure alarm display that outputs a sound and causes the LED 22 to blink, for example.

  On the other hand, if it is detected in step S31 that the alarm sound failure flag has been stored, the process proceeds to step S33, where the drive current passed through the LED 22 as a sensor failure alarm output by the alarm sound substitution process is increased and blinked, for example, and the LED 22 is made stronger. By making it shine, it compensates for the deterioration of the failure alarm function due to the absence of an alarm sound.

  FIG. 6 is a block diagram showing another embodiment of a stand-alone house alarm device. In this embodiment, a plurality of LEDs 22-1 to 22-n are provided in the notification unit 30, and an alarm is provided. A plurality of LEDs 22-1 to 22-n are driven as sound substitute processing.

  As the LEDs 22-1 to 22-n, there are provided, for example, a fire alarm LED 22-1, a low battery failure LED 22-2, a sensor failure LED 22-4, and an alarm sound failure LED 22-4. May be allowed. When the alarm processing unit 40 detects a fire by the event detection unit 38 and receives a signal indicating that, the alarm processing unit 40 turns on the fire alarm LED 22-1, detects a low battery failure, and receives a signal indicating that. In this case, the low battery failure LED 22-2 is turned on, and when the sensor failure is detected and a signal indicating that is received, the sensor failure LED 22-3 is turned on to detect the alarm sound failure and indicate that fact. When the signal is received, the alarm sound failure LED 22-4 is turned on. When the event detection unit 38 detects a fire, a low battery failure, or a sensor failure, the alarm processing unit 40 outputs an alarm sound corresponding to each content from the speaker 36.

On the other hand, the alarm sound substitute processing unit 50 detects a fire alarm, a low battery failure detection, or a sensor failure in a state where a warning sound failure is detected by the event detection unit 38 and a signal indicating the chest is received. When a signal is received, an alarm sound cannot be output from the speaker 36. Therefore, the LEDs 22-1 to 22-4 are simultaneously turned on, blinking, or blinking, for example, so that the user's attention is strongly attracted even if no alarm sound is output. This compensates for the deterioration of the alarm function due to the absence of an alarm sound.

  Since other configurations and functions are the same as those in the embodiment of FIG. 2, the same reference numerals are given and description thereof is omitted.

As a driving method of the LEDs 22-1 to 22-4, if a fire is detected, the LED 22-1 may blink, and the failure LEDs 22-2 to 22-4 may be turned on so that the alarm contents can be understood. In addition, the notification unit 30 includes two LEDs 22-1 and 22-1 of different colors, the LED 22-1 is used for a fire alarm, the LED 22-2 is used for a fault alarm, and the LED 22-1 and 22-2 are used for detecting an alarm sound fault. May be driven simultaneously. Of course, the LEDs 22-1 and 22-1 may be two-color LEDs.

FIG. 7 is an explanatory view showing an installation state of a monitoring system using an interlocked house guard according to the present invention 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 appearances of the home alarm devices 100-1 to 100-6 are basically the same as the stand-alone type home alarm device 10 shown in FIG. Hereinafter, the house alarm devices 100-1 to 100-6 are collectively referred to as the house alarm device 100 without being distinguished from each other.

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. Now event in the kitchen of a house 24 25, when the fire occurs, the fire to start an alarm is detected by the home alarm 100-1.

  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 To 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 police device 100 which received the event signal effectively performs relay transmission of the event signal as needed.

  As an alarm operation of the interlocking device 100-1 that is the interlock source, for example, a sweeping sound such as “Ppy fire is a fire” and a fire alarm sound indicating the interlock source of a predetermined pattern by a message are output and the LED 22 is lit, for example To display an alarm indicating the link source.

  On the other hand, in the interlocking destination home alarm devices 100-2 to 100-6, a sweeping sound such as “a separate alarm device has been activated” and a disaster warning sound indicating a predetermined pattern interlocking destination by a message are output. At the same time, for example, the LED 22 blinks to display an alarm indicating the interlocking destination.

  For example, a red LED and a yellow LED may be provided, and the two-color display in which the red LED is driven as the interlocking source and the yellow LED is driven as the interlocking destination. 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 100-1 to 100-6 are emitting an alarm sound, the alarm sound and alarm display stop processing is performed.

  At this time, for example, when the alarm stop operation is performed in the 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 ) Is stopped, and when the alarm stop operation is performed in any of the residence police 100-2 to 100-6 that are the interlocking destinations, the alarm of the interlocking source residence guard 100-1 is not stopped, The alarms of the interlocked residence alarm devices 100-2 to 100-6 are stopped.

  In addition, the home alarm device 100 executes a monitoring process for detecting a low battery failure from a drop in the voltage supplied from the battery power source as a built-in test in the background every predetermined cycle. A low battery failure alarm indicating the source (failure source) is output, and an event signal (low battery failure event signal) indicating a low battery failure is transmitted to other housing alarms, and a low level indicating the linkage destination (failure destination) Battery failure 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.

  Moreover, when the alarm stop switch that functions as an inspection switch is operated in the normal state, the home alarm device 100 detects a low battery failure by a monitoring process executed in the background as a built-in test. As an alarm, for example, “Battery is exhausted” is output continuously several times and the LED is lit, for example, and an event signal indicating a low battery failure (low battery failure event signal) is sent to another resident alarm. As a low battery failure alarm indicating a 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, when a low battery failure is not detected normally, the fire alarm sound “Check Woo Woo Fire Alarm has been activated” is output once at a low volume to check the speaker operation.

  In addition, the house alarm device 100 executes a monitoring process for discriminating a sensor failure in the background as a built-in test at a predetermined cycle, and outputs a sensor failure alarm indicating a link 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 alarm stop switch that functions as an inspection switch is operated in the normal state, or when a sensor failure is detected by a monitoring process executed in the background as a built-in test, the home alarm device 100 is linked from the speaker. For example, “pick failure” is output continuously several times as a failure alarm sound indicating the source (failure source), and the LED is turned on, for example. The display by turning on the LED is repeated a plurality of times.

  Also, when a sensor failure is detected, the home alarm device 100 transmits an event signal indicating a sensor failure (sensor failure event signal) to another home alarm device, for example, “a separate alarm device is faulty”. An alarm sound is output and a display different from the interlock source, for example, blinking is performed.

  Moreover, when the operation of the alarm stop switch that functions as an inspection switch is detected in the normal state, the home alarm 100 detects a sensor failure by a monitoring process executed in the background as a built-in test. For example, “failed battery” is output continuously several times as a failure alarm, the LED is lit, for example, and an event signal (sensor failure event signal) indicating a sensor failure is sent to another resident alarm, and the interlock destination (failure For example, “a separate alarm device is faulty” is continuously output a plurality of times as a sensor failure alarm indicating the first), and the LED is blinked, for example.

  On the other hand, when a sensor failure is not detected normally, a fire alarm sound “Woo Woo is a fire” indicating the interlocking source is output once at a low volume and the LED is lit, for example, in order to check the speaker operation.

  FIG. 8 is a block diagram showing an embodiment of a wireless liaison guard according to the present invention. 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 includes 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, 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 and the transmission circuit 142 together correspond to the transmission unit of the claims, and the antenna 131 and the reception circuit 144 together correspond to the transmission unit of the claims. Further, the signal received via the antenna 131 and the receiving circuit 144 is decoded by the event detection unit 158 provided in the processor 128. Hereinafter, the process up to this decoding may be referred to as reception. In particular, when the signal is determined to be valid as a result of decoding, it is called effective reception.

  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.

  A serial number 148 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.

  As the transmission source code 150, for example, a 26-bit multi-bit code code is used so that it does not overlap with any of the domestic alarms provided in the country, and for example, a serial number of a residential alarm is used.

  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 detection result by the monitoring function by periodic automatic inspection when the low battery failure flag 176 or the sensor failure flag 178 detects each failure. In addition, a periodic notification timer 182 that is used to output a periodic failure alarm after detecting a low battery failure or a sensor failure is provided. The periodic notification timer 182 may be arranged on a program executed by the processor 128 instead of being arranged in the memory 132.

  Furthermore, in this embodiment, an alarm sound failure flag 180 is stored as a failure detection result by periodic failure monitoring processing (automatic inspection), and the alarm sound failure flag 180 is an alarm sound of the speaker 156 provided in the notification unit 136. An alarm sound failure that becomes a failure of a speaker system indicating a deterioration or loss of output performance is shown.

  For example, the sensor unit 134 includes a smoke detector 116 that detects smoke and outputs a detection signal corresponding to the smoke density. 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, warning sounds, and the like held by a voice synthesis circuit unit (not shown) via an amplification unit (not shown). The LED 122 displays information such as a fire and a failure 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 an 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 On the other hand, when the alarm stop switch 120 is operated during the alarm indicating the interlock destination, the alarm sound is stopped and the alarm stop process is performed such that 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 a fire alarm or a failure alarm indicating an interlock source or an interlock destination is not performed, and an inspection operation is detected when the alarm stop switch 120 is operated in this state. It is detected whether or not the low battery failure flag 176 or the sensor failure flag 178 is stored in the memory 132, and if the failure flag is stored, a voice message indicating the content of the corresponding failure is output from the speaker 156 of the notification unit 136. A fault alarm is output.

If the failure flag is not stored in the memory 132 , the inspection result is normal, and the same alarm sound for speaker inspection as the fire alarm sound for inspecting the speaker 56 is output once at a low volume. The LED 122 is turned on.

  In addition, the inspection includes a battery failure detection and a sensor failure detection when the operation of the alarm stop switch 120 is detected in a normal state (when an inspection is instructed) without being automatically executed in the background after a built-in test. A predetermined check operation may be performed to notify the result.

  In addition, when an operation of the alarm stop switch 120 is detected during a fault alarm, the fault alarm stop process is performed after a predetermined inspection operation including a battery fault and a sensor fault is performed and the result is notified. May be. In this way, for example, the failure alarm stop process is performed after rechecking a 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 “Failure has been resolved” may be output to shift 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, and has a battery capacity of, for example, 10 due to a reduction in power consumption of the entire circuit unit including the wireless communication unit 130 in the residential alarm 100-1. The battery life of the year is guaranteed.

  The processor 128 is provided with functions of an event detection unit 158, an alarm processing unit 164, and an alarm sound substitution processing unit 174 as functions realized by executing the program.

  The event detection unit 158 detects the presence or absence of a fire detected from the detection signal output of the sensor unit 134, the presence or absence of an alarm stop instruction input or inspection instruction input by the operation unit 138, and the detection signal output of the sensor unit 134 decreases to detect a fire Detects events such as fire recovery, status failure, sensor failure, low battery failure, alarm sound failure indicating alarm sound performance degradation or loss.

  In addition, the event detection unit 158 receives the event signal received from the other residential alarm devices 100-2 to 100-6 via the antenna 131 and the receiving circuit 144, decodes this, and whether or not the event signal is effectively received and its Detect event contents. Moreover, the event detection part 158 relays and transmits the event signal received effectively from other mortgages as needed.

The alarm processing unit 164 receives a signal indicating that when the event detection unit 158 detects a fire as its own abnormality, instructs the notification unit 136 to perform control, and from the speaker 156, a predetermined pattern consisting of a sweep sound and a message The alarm sound indicating the link source is output, the LED 122 is turned on to display an alarm indicating the link source, and an event signal indicating a fire is transmitted to the other residential alarm devices 100-2 to 100-6. Let

  More specifically, the alarm processing unit 164 receives a signal indicating that a fire has been detected based on the smoke detection signal of the smoke detection unit 116 provided in the sensor unit 134 by the event detection unit 158. Based on this, the control unit 136 is instructed to control and the speaker 156 performs a control to repeatedly output an alarm sound indicating the link source, for example, a voice message “Woo Woo is a fire”, and turns on the LED 122 to indicate the link source. Alarm display control is performed, and an event signal indicating a fire is generated and transmitted to the other residential alarm devices 100-2 to 100-6 via the transmission circuit 142 and the antenna 131.

Further, the alarm processing unit 164 detects that the fire detection signal is effectively received from any of the other residential alarm devices 100-2 to 100-6 by the reception circuit 144 of the wireless communication unit 130, and the event detection unit 158 detects the fire event signal. When a signal indicating the effect is received, the alarm unit 136 is instructed to control, and an alarm sound (notification sound) indicating an interlocking destination of a predetermined pattern consisting of a sweep sound and a message is output from the speaker 156, for example, “a separate fire alarm device The alarm display control unit 168 causes the LED 122 to blink and display an alarm indicating the interlocking destination.

Further, the alarm processing unit 164 detects the operation of the alarm stop switch 120 while the event detection unit 158 outputs a fire alarm sound indicating the interlocking source or a fire alarm sound indicating the interlocking destination, or another residential alarm 100. When reception of an event signal indicating an alarm stop from any one of −2 to 100-6 or device event signal reception is detected, a signal indicating that is received to instruct control to the notification unit 136, and from the speaker 156 The output of the fire alarm by the voice message and the alarm display of the LED 122 is stopped. In this case, 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.

  Further, the event detection unit 158 is provided with a detection function for a low battery failure, a sensor failure, and an alarm sound failure.

  The detection of a low battery failure by the event detection unit 158 is performed by directly or indirectly supplying a power supply voltage supplied from the battery power supply 140 via a voltage detection circuit (not shown) at a predetermined measurement time interval, for example, T11 = 4 time intervals. Read by A / D conversion and compare with a predetermined threshold voltage. When the threshold voltage is lower than this threshold voltage, the low battery failure detection is preliminarily determined, and when the low battery failure detection tentative determination continues for a predetermined number of times, the low battery failure is detected. A battery failure is detected (confirmed), a low battery failure flag 176 is set, and the memory 132 is updated and stored.

  The detection of the sensor failure by the event detection unit 158 is performed by reading the smoke detection signal output from the smoke detection unit 116 of the sensor unit 134 by A / D conversion at a predetermined measurement time interval, for example, T12 = 1 second interval. The average value of the detected data for 100 minutes held in the buffer area of the memory 132 is obtained every predetermined time interval T13 = 100 minutes, for example, and this average value is determined at a predetermined reference level (zero point). When the output level is lower than the level), a failure of the sensor unit 134 is detected as being in an output stop state, and the sensor failure flag 178 is set and updated and stored in the memory 132.

  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 detection of the alarm sound failure by the event detection unit 158 detects the presence or absence of a failure by testing a sound output system (not shown) including the speaker 156 at a predetermined measurement time interval, for example, the same T11 = 4 hour interval as the low battery failure detection. . 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 determination (provisional determination) of alarm sound failure detection due to disconnection of speaker output line at the time of the alarm, and further detection of alarm sound failure (confirmation) when preliminary determination (provisional determination) of alarm sound failure detection continues for a predetermined number of times Then, the alarm sound failure flag 180 is set and updated and stored in the memory 132.

The event detection unit 158 not only loses the alarm sound output performance due to speaker disconnection or the like, but also deteriorates the alarm sound output performance due to an abnormal impedance or a drive circuit failure where the current (amplitude or average) flowing through the speaker line is not within a predetermined range. Also, for example, another threshold voltage higher than the threshold voltage used for the determination of disconnection of the speaker output line is set. If the threshold voltage is lower than that, the low alarm sound output performance is determined and the alarm sound failure flag 180 is set. The memory 132 is updated and stored.

  As described above, the monitoring process (automatic inspection) of the low battery failure detection unit 168, the sensor failure detection unit 170, and the alarm sound failure detection unit 172 in the present embodiment is executed in the background at a predetermined cycle as a build-in step.

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

  In addition, when an operation of the alarm stop switch 120 is detected during a fault alarm, a fault detection operation (check operation) including battery fault detection, sensor fault detection, and alarm sound fault detection is performed again and the result is notified. After that, a failure 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.

  When the event detection unit 158 detects a low battery failure and receives a signal indicating that fact, the alarm processing unit 164 instructs the notification unit 136 to perform control, and from the speaker 156 indicates a low source indicating the link source (failure source). As an alarm sound for battery failure, for example, “Battery is out of battery” is continuously output a plurality of times, and LED 122 is lit, for example. After that, the periodic notification timer 182 of the memory 132 is activated, and a sound output of “battery dead” and a blinking LED 122 are displayed a plurality of times at predetermined intervals based on the low battery failure flag stored in the memory 132. Repeat the process to be performed.

  In addition, when the event detection unit 158 detects a low battery failure and receives a signal indicating the fact, the alarm processing unit 164 generates a low battery failure event signal, and transmits another signal via the transmission circuit 142 and the antenna core 131. By sending the alarm to the home alarm device 100-2 to 100-6, the low battery failure alarm indicating the interlock destination is output as an alarm sound, and “Pick another alarm device is out of battery” is output, and the flashing display is different from the interlock source. To do.

In addition, when the event detection unit 158 detects a sensor failure by the sensor failure detection unit 170 and receives a signal indicating that, the alarm processing unit 164 instructs the notification unit 136 to perform control, and from the speaker 156, the link source ( As a sensor failure alarm sound indicating the failure source, for example, “pit failure” is continuously output a plurality of times, and the LED 122 is lit, for example. After that, the periodic notification timer 182 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 178 stored in the memory 132 is repeated. . At the same time, the alarm processing unit 164 generates a sensor failure event signal and transmits it to the other mortgage alarm devices 100-2 to 100-6. "The battery is out of battery" is output, and a blinking display different from the interlocking source is displayed.

  The alarm processing unit 164 receives a signal indicating that an inspection instruction operation (inspection instruction input) is detected by the operation of the alarm stop switch 120 that functions as an inspection switch in a normal state by the event detection unit 158, When it is detected that the low battery failure flag 176 is stored in 132, the notification unit 136 is instructed to control the speaker 156 to output, for example, “Battery dead” continuously several times, and the LED 122 is turned on. For example, a low battery failure event signal indicating an interlocking destination is generated by turning on and generating a low battery failure event signal and transmitting the low battery failure event signal to the other residential alarm devices 100-2 to 100-6 via the transmission circuit 142 and the antenna 131. The alarm is output as an alarm sound, “Another alarm device has run out of battery” and is different from the linkage source. The flashing display is performed.

  Further, the alarm processing unit 164 receives a signal indicating that an inspection instruction operation (inspection instruction input) due to the operation of the alarm stop switch 120 is detected by the event detection unit 158, and a sensor failure flag 178 is stored in the memory 132. If it is detected, the notification unit 136 is instructed to control the speaker 156 to output, for example, “pick failure” continuously several times, and the LED 122 is turned on, for example, and a sensor failure event signal is generated. Then, by transmitting to the other residential alarm devices 100-2 to 100-6 via the transmission circuit 142 and the antenna 131, the low battery failure alarm indicating the interlocking destination is used as an alarm sound. Is output, and a blinking display different from the link source is displayed.

  In this way, when the alarm stop switch 120 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.

The alarm processing unit 164 receives a signal indicating that an inspection instruction operation (inspection instruction input) due to the operation of the alarm stop switch 120 is detected by the event detection unit 158, and further stores an alarm sound failure flag 180 in the memory 132. When it is detected that there is no sound from the speaker 156 , the LED 122 is turned on, for example, an alarm sound failure event signal is generated, and another housing alarm device is transmitted via the transmission circuit 142 and the antenna 131. By transmitting to 100-2 to 100-6, 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. Make it. 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, the alarm processing unit 164 receives a signal indicating that an inspection instruction operation (inspection instruction input) due to an operation of the alarm stop switch 120 that functions as an inspection switch in a normal state is detected by the event detection unit 158 and receives a signal indicating that. If the low battery failure flag 176, the sensor failure flag 178, and the alarm sound failure flag 180 are not stored in 132, it is determined to be normal. In this case, the control unit is instructed to notify the notification unit 136 and the speaker 156 is normally alerted. In order to check the speaker to confirm that sound is output, “Woo Woo fire alarm has been activated” should be output once at a low volume as an alarm sound for speaker inspection that has the same content as the fire alarm sound. At the same time, the LED 122 is turned on to display an inspection.

  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 alarm processing unit 164 causes the failure detection unit 166 to detect a low battery failure. The sensor failure detection process (automatic inspection) is executed again, and if a failure is detected, a failure alarm is output, and if normal is detected, an alarm sound for speaker inspection is output and an alarm is displayed. good. Thereby, the latest inspection result can be notified.

Alarm sound substitute processing unit 174, when the alarm state has been detected warning sounding fault you including abnormal no longer out of the sound from the speaker 156 by the event detection unit 158, in the present embodiment,
(1) Increase in drive current of LED 122 (2) Simultaneous drive of a plurality of LEDs (3) Increase in transmission power of event signal to be transmitted to other house alarms (4) Event signal to be transmitted to other house alarms It is possible to cope with an increase in the transmission frequency.

  The increase in the LED drive current in (1) replaces an alarm when no alarm sound is produced by strengthening the light from the LED. The simultaneous driving of the plurality of LEDs in (2) can be handled when a plurality of LEDs are provided in the notification unit as shown in FIG. The increase in transmission power in (3) is replaced by the fact that an interlocking alarm is reliably performed by another house alarm device by receiving an event signal indicating a fire or failure. The increase in the transmission frequency of (4) is replaced by shortening the transmission interval of the event signal to be transmitted a predetermined number of times at the time of event detection, thereby speeding up the linked alarm by other residential alarms. In the following description, the increase in LED drive current (1) will be described as an example.

The alarm sound substitute processing unit 174 detects a warning sound failure without sound from the speaker 156 by the event detection unit 158 and the alarm detection failure flag 180 is stored in the memory 132. If the alarm processing unit 164 instructs the notification unit 136 to perform control and outputs a fire alarm sound from the speaker 136 when there is a signal indicating that detection, a sound is not generated. Increasing the driving current to increase the brightness, and even in a situation where no fire alarm sound is emitted, by turning on the light from the LED 122 intensified, so that the fire alarm indicating the interlocking source is transmitted to the user more reliably To.

In addition, the alarm sound substitute processing unit 174 is detected by the event detection unit 158 while the alarm sound failure flag 180 is stored in the memory 132 when the event detection unit 158 detects an alarm sound failure without sound from the speaker 156 , for example. If an effective reception of an event signal indicating a fire is detected from the home alarm device and a signal indicating that is received, the alarm processing unit 164 instructs the notification unit 136 to control and output a fire alarm sound. Since there is no sound, the drive current passed through the LED 122 is increased instead to increase the brightness, and even when there is no fire alarm sound, the light from the LED 122 is strengthened and blinked, so that it can be used more reliably. Communicating fire alarms indicating the link destination to the person.

  Here, the increase in the drive current that flows to the LED 122 by the alternative processing for the alarm sound failure is within a range that does not exceed the set average drive current for the alarm sound output that flows to the speaker 156, and the speaker 156 is functioning normally. The power consumption of the battery power supply 140 is equal to or less than

Further, the alarm sound substitute processing unit 174 detects that the event detection unit 158 detects an alarm sound failure without sound from the speaker 156 and the alarm sound failure flag 180 is stored in the memory 132. When a failure detection or a sensor failure detection is detected and a signal indicating that is received, there is no sound when the alarm processing unit 164 instructs control to the notification unit 136 to output a failure alarm sound. By increasing the drive current that flows through the LED 122 to increase the brightness, and even when the failure alarm sound is not emitted from the speaker 156, the light from the LED 122 is strengthened and turned on, so that the user can be surely notified of the failure. Try to tell.

  Also in this case, the increase in the drive current that flows to the LED 122 by the alternative processing for the alarm sound failure is within a range that does not exceed the set average drive current for the alarm sound output that flows to the speaker 156, and the speaker 156 functions normally. It is assumed that the degree of wear of the battery power supply 140 is equal to or less than that in the case of being present.

  FIG. 9 is an explanatory diagram schematically showing the format of the event signal used for the interlocking alarm in this 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 42 to 5 bits and 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 from the battery power supply 140 of the home guard 100-1 is started, in step S41, various settings including initialization, self-diagnosis, and prohibition mode setting are read and abnormalities are detected. If not, the process proceeds to step S42 to detect the presence or absence of a fire.

  When the smoke detection signal output from the sensor unit 134 exceeds a predetermined fire level, a fire is detected. In step S42, the presence of fire is detected, and the process proceeds to step S43. An event signal including a transmission source code to be identified, a group code, and an event code indicating a fire is generated and wirelessly transmitted to the other residential police.

Subsequently, in step S44, the presence or absence of storage of the alarm sound failure flag 180 is detected with reference to the memory 132. If the presence or absence of storage detection of the alarm sound failure flag 180 is not detected, the process proceeds to step S45, and the speaker 156 of the notification unit 136 A fire alarm indicating the interlocking source is output by lighting the fire alarm sound and the LED 122 .

  On the other hand, if it is detected in step S44 that the alarm sound failure flag 180 has been detected, the process proceeds to step S46, where the drive current to be supplied to the LED 122 is increased and turned on as a fire alarm output by the alarm sound substitution process, and the LED 122 is strongly turned on. It compensates for the deterioration of the fire alarm function that indicates the interlocking source due to the absence of an alarm sound.

  Subsequently, in step S47, 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, and when a fire recovery is detected, a serial number and a transmission source code are detected in step S48. After the event signal including the group code and the event code indicating the fire recovery is transmitted to the other house alarm device, the fire alarm indicating the interlocking source is stopped by the alarm sound from the speaker 156 and the blinking of the LED 122 in step S49. The alarm display by the LED 122 may be turned off after a predetermined time has elapsed.

Subsequently, in step S50 , 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 S51, where the serial number, transmission source code, group code, and alarm stop are set. An event signal including the event code to be generated is generated and transmitted to the other residential alarm, and the process proceeds to step S52 where the alarm sound output indicating the interlock source from the speaker 156 is stopped and the alarm display of the LED 122 is stopped. The LED 122 may be stopped after a predetermined time has elapsed.

  Subsequently, the process proceeds to step S53 in FIG. 11, and it is detected whether or not an event signal indicating a fire transmitted or relayed from another house alarm is effectively received. When it is detected that there is an effective reception detection of an event signal indicating a fire from another house alarm device, the process proceeds to step S54, the presence or absence of storage of the alarm sound failure flag 180 is detected with reference to the memory 132, and the alarm sound failure flag is detected. When the presence of the memory detection 180 is not detected, the process proceeds to step S55, and the fire alarm indicating the interlocking destination is output from the speaker 156 of the notification unit 136 by the fire alarm sound and the flashing of the LED 122.

  On the other hand, if it is detected in step S54 that the alarm sound failure flag 180 is detected, the process proceeds to step S56, where the drive current to be supplied to the LED 122 is increased and blinked as a fire alarm output by the alarm sound substitution process, and the LED 122 is made stronger. It compensates for the deterioration of the fire alarm function that indicates the interlocking destination due to the absence of an alarm sound.

  Note that the processing when an event signal indicating a low battery failure, a sensor failure, or an alarm sound failure is received from another housing alarm is omitted, but an event signal indicating a fire shown in steps S53 to S56 is received. Is basically the same as

  Next, in step S57, the presence / absence of effective reception of an event signal indicating fire recovery transmitted from another home police or relay transmission is detected, and the presence of effective reception of an event signal indicating fire recovery is detected. Proceeding to step S58, the alarm sound output from the speaker 156 and the alarm display by the LED 122, which are performed as the alarm of the interlocking destination, are stopped.

  Next, in step S59, when the presence or absence of effective reception of an event signal indicating an alarm stop transmitted from another home alarm is detected and the presence of effective reception of an event signal indicating an alarm stop is detected, Proceeding to S60, the presence or absence of an alarm is detected, and when the alarm is being detected, the process proceeds to step S61 to stop the output of the alarm sound as the interlocking destination and also stop the alarm display.

  Subsequently, the process proceeds to step S62 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 S63 and the low battery failure flag 176 is set and stored in the memory 132. The periodic notification timer 182 is activated.

  Subsequently, the process proceeds to step S64, where the presence or absence of storage of the alarm sound failure flag 180 is detected with reference to the memory 132, and if the presence of storage of the alarm sound failure flag 180 is not detected, the process proceeds to step S65 and the notification unit 136 A low battery failure alarm sound indicating the interlocking source is output from the speaker 156 by the low battery failure alarm sound and the lighting of the LED 122.

  On the other hand, if it is detected in step S64 that the alarm sound failure flag 180 is stored, the process proceeds to step S66, where the drive current passed through the LED 122 as a low battery failure alarm output by the alarm sound substitution process is increased and turned on. It compensates for the low battery failure alarm function that indicates the interlocking destination due to the absence of an alarm sound by shining strong.

  In step S67, an event signal including a serial number, a transmission source code, a group code, and an event code indicating a low battery failure is transmitted to another house alarm device to cause a failure alarm as a linkage destination.

  Subsequently, the process proceeds to step S68, where the presence / absence of a sensor failure is detected. When the sensor failure determination is detected, the process proceeds to step S69, where the sensor failure flag 178 is set and stored in the memory 132 and the periodic notification timer 182 is set. Start.

  Subsequently, the process proceeds to step S70, where the presence or absence of the storage detection of the alarm sound failure flag 180 is detected with reference to the memory 132, and when the presence of the storage of the alarm sound failure flag 180 is not detected, the process proceeds to step S71. From 156, a sensor failure alarm indicating the link source is output by turning on the sensor failure alarm sound and the LED 122.

  On the other hand, if it is detected in step S70 that the alarm sound failure flag 180 is stored, the process proceeds to step S72, where the drive current passed through the LED 122 is increased and turned on as a sensor failure alarm output by the alarm sound substitution process, and the LED 122 is strongly turned on. It compensates for the deterioration of the sensor failure alarm function indicating the interlocking destination due to the absence of an alarm sound by illuminating.

  Then, it progresses to step S73 and transmits the event signal containing the event code which shows a serial number, a transmission origin code | symbol, a group code | symbol, and a sensor failure to another residence police.

  Subsequently, the process proceeds to step S74, where the presence / absence of an alarm sound failure is detected. When the alarm sound failure determination is detected, the process proceeds to step S75, where the alarm sound failure flag 180 is set and stored in the memory 132 and the periodic notification is made. The timer 182 is started.

  Subsequently, in step S76, an alarm sound failure alarm indicating the failure source is performed. In this case, since no sound is output from the speaker 156, the failure display is performed only by turning on the LED 122, for example. Also in this case, the drive current passed through the LED 122 may be increased so that strong light is emitted from the LED 122.

  Subsequently, the process proceeds to step S77, where an event signal including a serial number, a transmission source code, a group code, and an event code indicating 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 blinking.

Subsequently, the process proceeds to step S78 in FIG. 13, where it is detected whether or not the regular ringing timing after a predetermined time has elapsed by the regular ringing timer 186 activated in step S63, S69 or S75. When the regular ringing timing is detected, step S79 is performed. It advances to, low battery fault flag 176 in the memory 132, the sensor fault flag 178 or alarm sound fault flag 180 is detected whether it is stored, the storage of any fault flag is detected the process proceeds to step S80, the memory 132, the presence / absence of storage of the warning sound failure flag 180 is detected, and if the storage of the warning sound failure flag 180 is not detected, the process proceeds to step S81, and a low battery failure or a sensor failure is detected from the speaker 156 of the notification unit 136. A fault that indicates the interlocking source by the corresponding alarm sound and lighting of the LED 122 To output an alarm.

  If it is detected in step S80 that the alarm sound failure flag 180 is stored, the process proceeds to step S82. If it is detected with reference to the memory 132 that the low battery failure flag 176 or the sensor failure flag 178 is stored, step S82 is performed. Proceeding to S83, lowering the alarm function of low battery failure or sensor failure due to no alarm sound by increasing the drive current to be sent to the LED 122 as sensor failure alarm output by alarm sound substitution processing and lighting the LED 122 strongly Make up.

  On the other hand, if it is not detected that the low battery failure flag 176 or the sensor failure flag 178 is stored with reference to the memory 132 in step S82, the process proceeds to step S84. In this case, only the alarm sound failure flag 180 is stored. The LED 122 is turned on to warn of an alarm sound failure. In addition, the alarm sound failure may be increased by increasing the drive current of the LED 122.

  Subsequently, the process proceeds to step S85, 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 S86, 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 S81, and the low battery failure flag is stored in the memory 132. 176, if the sensor failure flag 178 or the alarm sound failure flag 180 is not detected as being stored, it is detected that there is no failure detection (normal), and the process proceeds to step S88. The alarm sound is output once at a low volume and the LED 122 is turned on to display an inspection.

  On the other hand, if it is detected in step S87 that the low battery failure flag 176, the sensor failure flag 178, or the alarm sound failure flag 180 is stored in the memory 132, the process proceeds to step S89 to detect whether the alarm sound failure flag 180 is stored. If it is not detected that the alarm sound failure flag 180 is stored, the process proceeds to step S90, where an alarm sound corresponding to a low battery or sensor failure is output from the speaker 156 of the notification unit 136, and a failure alarm indicating the interlock source is output by lighting the LED 122. Let

If it is detected in step S89 that the alarm sound failure flag 180 is stored, the process proceeds to step S91. If it is detected that the low battery failure flag 176 or the sensor failure flag 178 is stored with reference to the memory 132, step S91 is performed. Proceeding to S92, increasing the drive current to be supplied to the LED 122 as a sensor failure alarm output by the alarm sound substitution process and lighting the LED 122, and causing the LED 122 to shine strongly, resulting in a low battery failure or a sensor failure alarm function deterioration.
