Abstract

PROBLEM TO BE SOLVED: To properly and promptly respond to the event of fire occurrence during acoustic pressure measurement test of a speaker by a linkage type alarm.SOLUTION: When a test execution part 68 detects a test execution operation by differently pushing an alarm stop switch 20 in a normal monitoring state, the test execution part 68 outputs a prescribed point in a fire alarm sound of a prescribed pattern, such as a sweep alarm sound to be subjected to acoustic pressure measurement test, as a test sound from a speaker 56. When a fire occurrence is detected during the test, a test interruption part 70 interrupts the acoustic pressure measurement test and outputs a fire alarm sound of a different pattern showing the fire occurrence during the test.

Description

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

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

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

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

  In such an interlocked house alarm system, when a fire is detected by the house alarm, the interlocking house alarm that detects the fire has a predetermined pattern of fire alarm sound including a message and an alarm sound, for example, “Woo Woo `` Check that the fire alarm has been activated '' is output, while the linked alarm device outputs a fire alarm sound such as `` Check that another fire alarm has been activated ''. ing. Here, the “woo-woo” portion of the fire alarm sound is a sweep sound from 2 Hz to 3 KHz, for example.

  In such an interlocking alarm system, a sound pressure measurement test is conducted to confirm that the required sound volume comes out from the speaker of the home alarm installed at the time of construction and periodic inspection of the house. ing. This sound pressure measurement test is suitable for sound pressure measurement in which a sound level meter is set at a certain distance from the home police device to be tested and the sound pressure of the fire alarm sound is constant and the frequency is changed. The peak value of the sound level meter is read at the timing when the sweep alarm sound “Woo Woo”, which is the fire alarm sound, is output.

  However, in a sound pressure measurement test using the sweep alarm sound in the fire alarm sound as a test sound, the measurer must use the sound level meter's guideline when the sweep alarm sound is output in the fire alarm sound that is repeatedly output. While shaking, it is necessary to read the peak value, and if the reading fails, it is necessary to wait until the test sound of the sweep warning sound is output again, which takes time and labor for the sound pressure measurement test. was there.

Therefore, in the conventional sound pressure measurement test, the test sound by the sweep warning sound suitable for the sound pressure measurement test in the sound warning signal is continuously output, and the sound pressure is not waited for the measurement timing when the sweep warning sound is output. The measurement test can be easily performed.

The flowchart which showed the detail of the remote processing of the sound pressure measurement test following FIG.

  FIG. 1 is an explanatory view showing an installation state of an alarm system using a house alarm of the present invention for a house. In the example of FIG. 1, a wireless dwelling alarm (for dwelling) that detects and alerts to fire in each of the warning areas of the living room, kitchen, children's room, master bedroom, and staircase provided in the house 24. Fire alarms) 10-1 to 10-5 are installed.

  The home alarm devices 10-1 to 10-5 have a function of transmitting and receiving event signals to and from each other wirelessly, and perform fire monitoring for corresponding monitoring areas in various places in the house. If a fire has occurred in the kitchen of the house 24, the home alarm device 10-1 in the fire occurrence place (kitchen) detects the fire and starts an alarm. Detecting this fire and initiating an alarm is referred to as “reporting” at the home alarm.

  When the home alarm device 10-1 issues a report, the home alarm device 10-1 functions as a link source, and an event signal indicating the occurrence of a fire to the other home alarm devices 10-2 to 10-5 as the link destination. Is transmitted wirelessly. When the other home alarm devices 10-2 to 10-5 receive an event signal indicating the occurrence of a fire from the home alarm device 10-1 of the interlocking source, an alarm operation as an interlocking destination by an alarm sound and an alarm display I do.

  Here, “effective reception” detects that this event signal has been received effectively when the group code included in the received event signal matches the group code registered in the memory. Moreover, the transmission source code | cord | chord is included in the event signal transmitted from residence police device 10-1 to 10-5 as identification information which shows the residence police device of a transmission origin, for example. In addition, the residence guard which received the event signal effectively performs relay transmission of the event signal as necessary.

  Self-events detected by the home alarm include not only the above-mentioned fire occurrence but also fire recovery, alarm stop operation, sound pressure measurement test execution operation, etc., and reception of various event signals from other alarm devices Is also included. These will be described later.

  As an alarm operation of the home alarm device 10-1 that is the interlocking source, for example, a warning sound of a predetermined pattern including an alarm sound and a message such as “Please confirm that the Woo Woo fire alarm has been activated” is output. On the other hand, fire alarm sounds such as “Please confirm that another fire alarm has been activated” are output for the linked home alarm devices 10-2 to 10-5.

  Among such fire alarm sounds, the “woo-woo” part is a sweep alarm sound in which the signal amplitude of the fire alarm signal driving the speaker is constant and the frequency changes at, for example, 2 to 3 KHz, and the sound pressure measurement in this embodiment In this case, the sweep sound “Woo-woo” in the fire alarm sound is continuously output as the test sound to be subjected to the sound pressure test.

  Moreover, as a display (referred to as an alarm display) accompanying the alarm of the home alarm device 10-1 that is the interlocking source, for example, an LED is turned on. On the other hand, in the interlocked residence police 10-2 to 10-5, the LED is blinked. As a result, the alarm display by the LED in the interlock source alarm and the interlock destination alarm can be distinguished.

  The interlocking source LED may be blinking and the interlocking destination LED may be blinking, or the same LED may be blinking or blinking or lit for both the interlocking source alarm and the interlocking destination alarm. Further, for example, a red LED and a yellow LED may be provided, and the two-color display may be performed such that the interlocking source drives the red LED and the interlocking destination drives the yellow LED. Of course, a two-color LED capable of emitting both red and yellow by combining two LEDs can be adopted. In addition, a liquid crystal display or the like may be used.

  When the alarm stop switch is operated in a state in which the house alarm devices 10-1 to 10-5 are emitting an alarm sound, the alarm sound and alarm display stop processing is performed.

  At this time, for example, when the alarm stop operation is performed in the home alarm device 10-1, which is the interlocking source, alarms (alarm sound output and / or alarm display output) of all the home alarm devices 10-2 to 10-5 ) Is stopped and the alarm stop operation is performed in any of the home police 10-2 to 10-5 that are the interlocking destinations, the alarm of the home police 10-1 does not stop, and the home police The alarm of 10-2 to 10-5 is stopped. In addition, in the following description, when calling the housing alarms 10-1 to 10-5 without distinguishing, they are called the housing alarms 10.

  FIG. 2 is an explanatory view showing the appearance of the home alarm according to the present invention, in which FIG. 2 (A) shows a front view and FIG. 2 (B) shows a side view. The side provided with the attachment hook 15 is the upper side.

  In FIG. 2, the housing of the residential alarm 10 according to the present embodiment includes a cover 12 and a main body 14. A plurality of smoke inlets are opened in the center of the cover 12, and a smoke detector 16 is disposed inside the cover 12, so that a fire is detected when smoke from the fire reaches a predetermined concentration.

  A plurality of openings provided in the cover 12 are provided with a smoke detector 16, and an acoustic hole 18 is provided in the lower left side of the smoke detector 16. A fire alarm sound with a predetermined pattern combined can be output. The fire alarm sound does not necessarily include a voice message.

  When the sound pressure measurement test is executed, the sweep alarm sound portion of the fire alarm sound is continuously output from the speaker as a test sound for sound pressure measurement over a predetermined time.

  An alarm stop switch 20 is provided below the smoke detector 16. The alarm stop switch 20 also functions as an inspection switch that instructs self-inspection of the function of the home alarm device 10. For example, when the alarm stop switch 20 is operated during a fire alarm, the alarm is stopped, and when the alarm stop switch 20 is operated in a normal state, a function check is performed and the result is notified. Here, the normal state refers to a state at least during a fire alarm and a failure alarm.

  Further, in the present embodiment, when the alarm stop switch 20 is pressed in the normal monitoring state, for example, when the alarm stop switch 20 is pressed long, the sound pressure measurement test execution operation is discriminated, and the sweep alarm sound in the fire alarm sound is detected from the speaker. This part functions as a test execution switch for a sound pressure measurement test in which the part is continuously output as a test sound for a predetermined time.

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

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

  In addition, in the residential alarm 10 of FIG. 2, although the smoke detector 16 is provided and the fire alarm which detects a fire based on the smoke which generate | occur | produces with a fire is taken as an example, in addition to this, with a fire House alarm with temperature sensor such as a thermistor that detects fire based on generated heat, house alarm to detect other physical phenomena associated with fire, alarm to detect gas leaks other than fire, intruder Various alarm devices that detect earthquakes and other abnormalities (abnormalities), and alarm devices formed by combining these alarm devices are also included in the scope of the present invention. The alarm system of the present invention may be configured by mixing these various alarm devices.

  FIG. 3 shows the sound pressure measurement test by the house alarm corresponding to the first invention of the present application and the operation when a fire occurs during the test.

  FIG. 3 (A) shows the state of the sound pressure measurement test, and the sound pressure measurement test of the residential police device 10-1 among the residential police devices 10-1 to 10-5 is taken as an example. When performing the sound pressure measurement test of the residence guard 10-1, the noise meter 26 is installed at a position 1 m away from the residence guard 10-1. Subsequently, when the alarm stop switch 20 of the home alarm device 10-1 is pressed and operated, the sound pressure measurement test execution operation is determined from the switch signal of the alarm stop switch 20, and the sound pressure measurement test is executed.

  For example, the sound pressure measurement test can be performed continuously for a predetermined time with the sweep alarm sound “Woo Woo” in the fire alarm sound “Woo Woo fire alarm activated” indicating the interlocking source as the test sound 25. Output to. During the output of the test sound, the measurement person reads the peak value of the sound level meter 26 and, for example, if a measured value of, for example, 70 dB / m or more is obtained as the peak value of the sound level meter 26, it is determined as normal.

  FIG. 3 (B) shows an operation in the case where a fire occurrence is determined in another residential alarm 10-3 during the sound pressure measurement test in the residential alarm 10-1. If a fire occurrence is determined in the residential alarm 10-3 during the sound pressure measurement test of the residential alarm 10-1, the residential alarm 10-3 outputs a fire alarm sound 27 indicating the interlocking source, and at the same time fires. The event signal is transmitted to the other residential alarm devices 10-1, 10-2, 10-4, and 10-5.

  Upon receiving this fire event signal, the Dwelling Unit 10-1 under test interrupts the sound pressure measurement test, so that the output of the test sound is interrupted, and subsequently a fire alarm sound indicating the link destination is output. Become. Of course, the fire alarm sound which shows an interlocking | linkage destination is output in other residence alarm devices 10-2, 10-4, and 10-5.

  The fire alarm sound that indicates the link destination is `` Wu-woo, check that another fire alarm has been activated '', but for the residential alarm that interrupted the sound pressure measurement test, it was confirmed that a fire occurred during the test. For example, “Woo-woo check that another fire alarm has been activated during the test” is output as a fire alarm sound including the message.

  Thus, by including a message indicating that a fire has occurred during the test in the message of the fire alarm sound from Dwelling Unit 10-1 that interrupted the sound pressure measurement test, the fire alarm sound after the test interruption is included. It is possible to prevent misunderstanding as a test sound for sound pressure measurement, and the measurer can quickly recognize the fire and enable quick initial fire extinguishing and evacuation.

  FIG. 4 is a block diagram showing an embodiment of the residential alarm according to the first invention of the present application for performing the sound pressure alarm test 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. Moreover, in FIG. 4, although it has shown about the residence guard 10-1 installed in the kitchen, it becomes the same structure also about the other residence guards 10-2 to 10-5.

  In FIG. 4, the home alarm device 10-1 includes a processor 28 known as a one-chip CPU. For the processor 28, a wireless communication unit 30 including an antenna 31, a memory 32, a sensor unit 34, a notification unit 36, An operation unit 38 and a battery power source 40 are provided.

  The wireless communication unit 30 is provided with a transmission circuit 42 and a reception circuit 44 so that event signals can be transmitted and received wirelessly between the other residential alarm devices 10-2 to 10-5. As the wireless communication unit 30, in Japan, for example, STD-30 (wireless equipment standard of a low power security system wireless station) or STD-T67 known as a standard of a specific low power wireless station of 400 MHz band. It has a configuration that conforms to the standard for specific low-power radio station telemeters, telecontrol and data transmission radio equipment.

  Of course, when the wireless communication unit 30 is used outside Japan, the wireless communication unit 30 has contents compliant with the standard of the assigned wireless station in that region. The antenna 31, the transmission circuit 42, and the transmission processing unit 62 are collectively referred to as a transmission unit, and the antenna 31, the reception circuit 44, and the reception processing unit 64 are collectively referred to as a transmission unit.

  The memory 32 includes a serial number 48, which is a serial number indicating the order of event signals, a transmission source code 50 serving as resident alarm identification information for identifying each resident alarm, and a resident alarm installed in a house as shown in FIG. The group code | symbol 52 for comprising the interlocking group which performs an interlocking alarm by 10-1 to 10-5 is stored.

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

  The source code 50 is, for example, a 26-bit multi-bit code code so as not to be duplicated with any of the domestic alarms provided in the country. For example, the serial number of the local alarm or the earthquake early warning device is used. We are using.

  Re-relay can be permitted or prohibited using the serial number 48 or the transmission source code 50, and by performing processing to avoid unnecessary communication, optimal relay can be performed as necessary. Further, for example, an event signal relayed and transmitted by the interlocking destination terminal is added with the source code of the interlocking source terminal in addition to the transmission source code of the interlocking destination terminal, and is re-started from the interlocking source terminal source code. It is also possible to 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 52 is a code that is set in common to a plurality of residential alarms constituting the interlocking group, and the group code included in the event signal received by the wireless communication unit 30 is the group code 52 registered in the memory 32. When they match, this event signal is processed as a valid signal, and unnecessary linkage with an alarm device belonging to another group that is installed in a neighboring house or the like and does not require linkage can be avoided.

  The group code 52 is a code that is set in common to a plurality of residential alarms constituting the interlocking group, and the group code included in the event signal received by the wireless communication unit 30 is the group code 52 registered in the memory 32. When they match, this event signal is processed as a valid signal, so there is no need to install it in a neighboring house, etc. that is installed in a neighboring house, etc. Interlocking can be avoided.

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

  The notification unit 36 is provided with a sound amplifier 55 and a speaker 56 for outputting an alarm sound or the like, and an LED 22 for displaying an alarm or the like. The speaker 56 outputs various messages, alarm sounds and the like held by itself from a voice synthesis circuit unit (not shown). The LED 22 displays an abnormality such as a fire by blinking, blinking, or lighting. Instead of the speaker 56, a buzzer or the like may be used. Further, instead of the LED 22, a two-color LED, a liquid crystal display, or the like may be provided. Of course, an LED and a liquid crystal display may be provided together.

  The operation unit 38 is provided with an alarm stop switch 20. The alarm stop switch 20 functions as an alarm stop switch when the alarm unit 36 outputs a warning sound of a fire or a failure from the notification unit 36 or when an alarm display is performed by the LED 22. For example, if the alarm stop switch 20 is operated during an alarm indicating the interlock source, the alarm sound and the alarm display are stopped, and if the alarm stop switch 20 is operated during the alarm indicating the interlock destination, the alarm sound is stopped, but the alarm display is Alarm stop processing is performed such as stopping after a predetermined time from the stop or stop of the alarm sound.

  The alarm stop switch 20 functions as an inspection switch in a normal monitoring state in which an alarm indicating the interlocking source or the interlocking destination is not performed. When the alarm stop switch 20 is operated in this state, a predetermined self-inspection operation is performed. And a voice message indicating the inspection result is output from the speaker 56 of the notification unit 36.

  Further, the alarm stop switch 20 functions as a sound pressure measurement test execution switch for instructing execution of the sound pressure measurement test by a push operation in the normal monitoring state. That is, when the alarm stop switch 20 is pressed and pressed for 2 to 3 seconds or more in the normal monitoring state, the sound pressure measurement test execution operation is determined from the switch instruction input at this time, and the sweep alarm sound is set as the sound pressure measurement target. A sound pressure measurement test is performed in which the test sound is continuously output for a predetermined time.

  During the output of the test sound for the sound pressure measurement test, the alarm stop switch 20 functions as a test sound stop switch, and the output of the test sound over a predetermined time can be stopped whenever necessary. Thereby, when the sound pressure measurement by the sound level meter is completed within a predetermined time, it is possible to prevent the test sound from being unnecessarily continued by performing the stop operation.

  When the alarm stop switch 20 is operated during the fault alarm, the fault alarm stop process may be performed after performing a predetermined self-inspection operation and informing the result. In this way, for example, the failure alarm stop process is performed after rechecking the sensor failure or the like, so that the user can be made to recognize the failure state more clearly. At this time, if the failure state has been resolved (failure recovery), for example, a message such as “the failure has been resolved” may be output, and the processing may be shifted to the failure stop processing (failure recovery processing).

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

  The processor 28 is provided with a monitoring control unit 58 as a function realized by executing the program. The monitoring control unit 58 includes an event detection unit 60, a transmission processing unit 62, a reception processing unit 64, and an alarm processing unit 66. Features are included. The processor 28 is provided with functions of a test execution unit 68 and a test interruption unit 70 corresponding to the sound pressure measurement test.

  The event detection unit 60 has the presence or absence of a fire detected from the detection signal output of the sensor unit 34, the presence or absence of an alarm stop instruction input, inspection instruction input or test execution instruction input by the operation unit 38, and the detection signal output of the sensor unit 34 decreases. To detect an event such as a fire recovery that will clear the fire detection status. Further, the event detection unit 60 detects the presence / absence of event signal effective reception obtained as a result of decoding an event signal from another resident alarm and the contents of the event via the receiver circuit 44 and the reception processing unit 64.

  The transmission processing unit 62 detects the fire from the detection signal output of the sensor unit 34 by the event detection unit 60, stops the alarm by the operation unit 38, and recovers the fire from which the detection signal output of the sensor unit 34 is reduced to eliminate the fire detection state. When a self event such as the above is detected, an event signal indicating the detected event is sent from the antenna 31 via the transmission circuit 42 of the wireless communication unit 30 to the other resident guards 10-2 to 10-5 that are linked to each other. To send to. Moreover, the transmission process part 62 relays and transmits the event signal received effectively from other residence police devices 10-2 to 10-5 as needed. The reception processing unit 64 receives and decodes the event signals from the other mortgages 10-2 to 10-5 via the antenna 31 and the reception circuit 44 of the wireless communication unit 30.

  The alarm processing unit 66 receives a signal from the event detection unit 60 when the event detection unit 60 detects a fire as its own abnormality, outputs an alarm sound indicating the interlocking source from the speaker 56 of the notification unit 36, and turns on the LED 22. For example, the lighting display is performed to display an alarm indicating the interlocking source, and further, a fire event signal is transmitted to another residential alarm.

  Specifically, when the event detection unit 58 detects a fire based on the smoke detection signal of the smoke detection unit 16 provided in the sensor unit 34, the alarm processing unit 66 receives a signal indicating that from the event detection unit 58. In response to this, the alarm unit 36 is controlled to repeatedly output an alarm sound indicating the link source from the speaker 56, for example, “Woo Woo Fire is Fire”, and the LED 22 is turned on to indicate the link source. The alarm display control is performed, and an event signal indicating a fire is further transmitted from the antenna 31 to the other residential alarm devices 10-2 to 10-5 by the transmission circuit 42 of the wireless communication unit 30 via the transmission processing unit 62. .

  Further, the alarm processing unit 66 receives a fire event signal from any of the other residential alarm devices 10-2 to 10-5 by the reception circuit 44 of the wireless communication unit 30, and becomes effective in the reception processing unit 64. , For example, “Please confirm that another fire alarm has been activated” is repeatedly output from the speaker 56 of the notification unit 36 as a fire alarm sound (notification sound), and at the same time, the LED 22 blinks to indicate the interlock destination. A warning display is displayed.

  The alarm processing unit 66 detects an operation of the alarm stop switch 20 during the output of the fire alarm sound indicating the interlock source or the fire alarm sound indicating the interlock destination, or an event signal indicating the alarm stop from another residential alarm device. When it is detected that there is valid reception or device event signal valid reception, the output of the fire alarm by the voice message from the speaker 56 and the alarm display of the LED 22 is stopped. At this time, the alarm display by the LED 22 may be stopped after continuing for a predetermined time. It should be noted that during the fire alarm indicating the interlocking source, at least the output of the alarm sound may be continued even if the event signal indicating the alarm stop or the device event signal is effectively received.

  Here, the event detection unit 60 detects a low battery and a fault sensor fault as faults. The low battery failure is detected by A / D conversion of the power supply voltage supplied from the battery power supply 40 directly or indirectly through a voltage detection circuit (not shown) at a predetermined measurement time interval, for example, T1 = 4 time intervals. Read and compare with a predetermined threshold voltage. When the voltage is lower than this threshold voltage, the low battery failure detection is preliminarily determined, and when the low battery failure detection is continuously determined for a predetermined number of times, it is determined that the low battery failure is detected ( Confirm) and set the low battery failure flag and store it in the memory 32.

  The sensor failure is detected by reading the smoke detection signal output from the smoke detector 16 of the sensor unit 34 at a predetermined measurement time interval, for example, T2 = 1 second by A / D conversion, and holding it in the buffer area of the memory 32. For example, for every predetermined time interval T3 = 10 minutes, an average value of 10 minutes of detection data held in the buffer area of the memory 32 is obtained, and this average value falls below a predetermined reference level (referred to as a zero point level). If it is determined that the output is stopped, the sensor unit 34 is determined to be faulty, and a sensor fault flag is set and stored in the memory 32.

  The reason why the 10-minute average value of the smoke concentration detection signal falls below the zero point level is that the failure of the light receiving element provided in the smoke detector 16, the disconnection of the output signal line from the light receiving element, the stop of the light receiving amplifier, etc. 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 34, a sensor failure can be similarly detected by various processes. In addition, disconnection of the output line to the speaker 56, other circuit failures, communication abnormalities, and the like can be similarly monitored. Such a failure is also collectively referred to as a sensor failure in the present embodiment because the same processing as the sensor failure is performed after detection.

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

  In addition, when the event detection unit 60 detects a low battery failure, the alarm processing unit 66 uses, for example, “Battery is out of battery” as a low battery failure failure alarm sound indicating the link source (failure source) from the speaker 56 of the notification unit 36. Is repeatedly output a predetermined number of times, and the LED 22 is blinked, for example, and thereafter, “battery is exhausted” is output once every predetermined time, and the display output by the LED 22 is also periodically repeated.

  In addition, the alarm processing unit 66 transmits an event signal indicating a low battery failure to other housing alarms, and as a low battery failure alarm indicating the linkage destination, “a separate alarm device is out of battery” or “beep alarm”. A warning alarm sound is displayed indicating that the instrument is out of battery and a blinking display different from the interlocking source is displayed.

  In addition, when the event detection unit 60 detects a sensor failure, the alarm processing unit 66 uses, for example, a “pick failure” failure alarm sound as a sensor failure alarm sound indicating the link source (failure source) from the speaker 56 of the notification unit 36. Is repeatedly output a predetermined number of times, and the LED 22 is blinked, for example, and then a failure alarm sound of “pick failure” is output once every fixed time and the display output by the LED 22 is also periodically repeated. .

  In addition, the alarm processing unit 66 transmits an event signal indicating a sensor failure to the other residential alarm devices 10-2 to 10-5 via the transmission processing unit 62 and the transmission circuit 42, thereby indicating a sensor failure alarm indicating the interlock destination. Is output. At this time, for example, “a separate alarm device is faulty” or “a short alarm device is faulty” is output as a failure alarm sound, and a blinking display different from that of the interlock source is performed.

  Further, when the alarm processing unit 66 detects an inspection instruction input by operating the alarm stop switch 20 in a normal state by the event detection unit 60, the low battery failure flag or the sensor failure flag is stored in the memory 32 at that time. In this case, a failure alarm corresponding to each failure flag is issued from the notification unit 36 with an alarm sound and an alarm display as a link source (failure source), and at the same time, an event signal indicating a low battery failure or a sensor failure is sent to another resident alarm device. 10-2 to 10-5 are transmitted with an alarm sound and an alarm display as an interlocking destination (failure destination).

  Further, when the alarm processing unit 66 detects the alarm stop operation of the alarm stop switch 20 provided in the operation unit 38 during the output of the sensor failure indicating the interlocking source or the low battery failure alarm, the alarm processing unit 66 generates an alarm sound indicating the own interlocking source. Stop and stop after the failure display continues for a predetermined time, and further send an event signal indicating the alarm stop to the other dwelling alarm devices 10-2 to 10-5 that are outputting the failure alarm indicating the interlocking destination. Stop sound and fault indication.

  Next, functions of the test execution unit 68 and the test interruption unit 70 will be described. The test execution unit 68 detects an instruction input of a long press operation that is a press operation of the alarm stop switch 20 in the normal monitoring state, and determines whether there is an execution operation of the sound pressure measurement test.

  In other words, when the event detection unit 60 detects an instruction input by a long press operation of the alarm stop switch 20 in the normal monitoring state, the test execution unit 68 determines that there is a sound pressure measurement test execution operation, and the link source or link destination A sound pressure measurement test is performed from the speaker 56 of the notification unit 36 using the position of the sweep alarm sound “Woo-woo” to be subjected to sound pressure measurement in a predetermined pattern of fire alarm sound including a combination of an alarm sound and a message indicating the sound as a test sound. The sound pressure measurement test is repeatedly performed for a predetermined time required for the measurement, for example, for one minute.

  Prior to the execution of the sound pressure measurement test, as shown in FIG. 3, the measurer prepares and installs the sound level meter 26 in advance, for example, 1 meter before the house police 10-1 to perform the sound pressure measurement test. When the sound pressure measurement test is executed, the peak value of the test sound output from the speaker 56 is measured, and if it is 70 dB / m or more, it is determined to be normal.

  The test execution unit 68 ends the sound pressure measurement test when it is determined that the alarm stop switch 20 is being operated during the output of the alarm sound.

  During the sound pressure measurement test by the test execution unit 68, that is, during the continuous output of the sweep alarm sound “Woo-woo” for a predetermined time, the test interruption unit 70 fires by the event detection unit 60 of the monitoring control unit 58. When the occurrence is determined, the sound pressure measurement test in which the sweep alarm sound “Woo-woo” is continuously output from the speaker 56 is interrupted, and the fire alarm sound corresponding to the occurrence of the fire is output from the speaker 56.

  Here, in order to determine the occurrence of fire by the event detection unit 60, the case where the home alarm device 10-1 itself determines the occurrence of a fire and the validity of the fire event signal from the other home alarm devices 10-2 to 10-5. Although the occurrence of a fire may be determined by reception, it is important to notify the occurrence of a fire at another location during the sound pressure measurement test. When it is determined that a fire has occurred due to the effective reception of the event signal, the sound pressure measurement test is interrupted, and a fire alarm sound indicating the link destination is output from the speaker 56.

  Therefore, when the test interruption unit 70 determines that a fire has occurred due to the effective reception of fire event signals from the other residential alarm devices 10-2 to 10-5 during the sound pressure measurement test, the test sound using the sweep warning sound is used. After interrupting "Woo Woo", fire alarm sound indicating the link destination is output.

  Further, the test interruption unit 70 more preferably uses a sweep alarm sound when it is determined that a fire has occurred during the sound pressure measurement test by effective reception of fire event signals from the other residential alarm devices 10-2 to 10-5. For example, “Woooo during the test, another alarm was activated during the test.” "Please check" to clearly indicate that a fire has occurred during the test.

  FIG. 5 is an explanatory diagram schematically showing the event signal format used for the linked alarm in the present embodiment. In FIG. 5, the event signal 46 includes a serial number 48, a transmission source code 50, a group code 52, and an event code 54.

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

  The transmission source code 50 is, for example, a 26-bit code used as residence warning device identification information, and uses, for example, the serial number of the residence warning device 10 and the earthquake early warning device 25. The group code 52 is an 8-bit code, for example, and the same group code is set, for example, for the residential alarm devices 10-1 to 10-5 shown in FIG.

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

The event code 54 is a code representing event contents such as a fire, a gas leak (for example, in the case of a gas leak alarm device or a residence alarm device having a gas leak detection function), and is 4 bits in the embodiment of FIG. 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. Here, 0000 is used for periodic notification, for example, without event detection.

  By increasing the number of bits of the event code 54 to 5 bits and 6 bits, more event contents can be expressed. For example, the recovery event code may be divided into fire recovery, gas recovery, and failure recovery.

  6 and 7 are flowcharts showing an example of the monitoring process in the residential alarm 10 of FIG. In FIG. 6, when the power supply by the battery power supply 40 of the mortgage alarm device 10 is started, various settings including initialization, self-diagnosis, and prohibition mode setting are read in step S1, and if there is no abnormality. In step S2, the presence or absence of a fire is detected.

  When the smoke detection signal output from the sensor unit 34 exceeds a predetermined fire level, a fire is detected in step S2 and the process proceeds to step S3, where a serial number and a sender code for identifying a house alarm detecting the fire, After transmitting a fire event signal including a group code and an event code indicating a fire to another house alarm, in step S4, a fire alarm sound such as a voice message or a buzzer sound from the speaker 56 of the notification unit 36 and a lighting of the LED 22, for example, A fire alarm indicating the link source is output according to the alarm display.

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

  Subsequently, in step S8, the presence or absence of an alarm stop instruction operation of the alarm stop switch 20 is detected. When the switch operation is detected, the presence or absence of an alarm is detected in step S9. When an alarm is detected in step S9, the process proceeds to step S10, and an alarm stop event signal including a serial number, a transmission source code, a group code, and an event code indicating an alarm stop is sent to the other residential alarm devices 10-2 to 10-. 5, the process proceeds to step S <b> 11, the alarm sound output indicating the interlock source from the speaker 56 is stopped, and the alarm display by turning on the LED 22 is turned off. The LED 22 may be turned off after a predetermined time has elapsed.

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

  Subsequently, the process proceeds to step S12 in FIG. 7 to detect the presence or absence of effective reception of an event signal indicating a fire transmitted or relay-transmitted from another house alarm device. When the effective reception of an event signal indicating a fire from another house alarm is detected, the process proceeds to step S13 to output an alarm sound from the speaker 56 as a fire alarm indicating the interlocking destination, and an alarm display by blinking of the LED 22 is performed.

  Next, in step S14, it is detected whether or not an event signal indicating a fire recovery transmitted or relayed from another house police device is received, and if an event signal indicating a fire recovery is detected, the process proceeds to step S15. The alarm display by the alarm sound output from the speaker 56 and the blinking of the LED 22 which is performed as an alarm at the interlocking destination is stopped.

  Next, in step S16, the presence or absence of effective reception of an event signal indicating an alarm stop transmitted or relayed from another resident alarm is detected, and when the effective reception of an event signal indicating an alarm stop is detected, the process proceeds to step S17. The process proceeds to detect whether or not an alarm is present. When the alarm is detected, the process proceeds to step S18 to stop the alarm sound output as the interlocking destination and to stop the alarm display. Subsequently, a sound pressure measurement test process is executed in step S19.

  FIG. 8 is a flowchart showing details of the sound pressure measurement test process in step S19 of FIG. In FIG. 8, in step S20, the presence / absence of a sound pressure measurement test execution operation is detected. When an instruction input is detected by long-pressing the alarm stop switch 20 in the normal monitoring state, an execution operation of the sound pressure measurement test is detected in step S20, and the process proceeds to step S21 to fire a predetermined pattern indicating the interlocking source or the interlocking destination. The alarm sound signal of the sweep alarm sound “Woo Woo”, which is the target of sound pressure measurement in the alarm sound, is generated and continuously output by the speech synthesizer circuit, and the sweep alarm sound from the speaker 56 is continuously output as the test sound. .

  Subsequently, the presence or absence of a predetermined time has been detected in step S22, and the presence or absence of a fire has been detected in step S23 until the predetermined time has been detected, and the passage of a predetermined time has been detected without detecting the presence of a fire. Then, it progresses to step S24 and the test sound by the sweep warning sound output from the speaker 56 is stopped, and a sound pressure measurement test is complete | finished.

  On the other hand, if a fire is detected from the fire event signal that is effectively received from the other residential alarm devices 10-2 to 10-5 during the test in the continuous output of the test sound for a predetermined time in step 23, that is, during the test, the process proceeds to step S25. The sound pressure measurement test is interrupted and the output of the test sound from the speaker 56 is stopped. Subsequently, in step S26, the output of the fire alarm sound indicated by the interlocking destination and the alarm display are performed.

  During the output of the fire alarm sound, the presence or absence of the alarm stop is detected in step S27. When the alarm stop is detected, the process proceeds to step S28 to stop the fire alarm sound and the alarm display. In addition, detection of the alarm stop in step S27 is detection of the operation instruction input of the alarm stop switch 20, detection of the effective reception of the event signal indicating the fire recovery from the other home alarm devices 10-2 to 10-5, or other This is a case where any of the detection of the effective reception of the event signal indicating the alarm stop from the home alarm is determined, and the details thereof are the contents shown in steps S to S11 of FIG. 6 and steps S14 to S18 of FIG. Become.

  FIG. 9 shows the remote sound pressure measurement test of the home police device according to the second invention of the present application and the operation in the event of a fire during the test. An event signal indicating a sound pressure measurement test is transmitted to a remote test.

  FIG. 9 (A) shows the state of the sound pressure measurement test, and the operation of the sound pressure measurement test is performed by the residence police 10-1 among the residence police 10-1 to 10-5. The state which is performing the remote test of the residence guard 10-3 in the devices 10-2 to 10-5 is shown.

  In the remote test operation of the present embodiment, as shown in FIG. 3, when the sound level meter 26 is first placed on the home alarm device 10-1 where the test operation is performed and the alarm stop switch 20 is operated for a long time, sound pressure measurement is performed. The execution operation of the test is discriminated, and the sweep alarm sound “Woo-woo” in the fire alarm sound is continuously output as a test sound from the speaker of the residential alarm 10-1, the peak value is read by the sound level meter 26, and 70 dB / M or more is judged as normal. In addition, when the fire event signal that is effectively received from the other housing police devices 10-2 to 10-5 is effectively received during the sound pressure measurement test of the housing police device 10-1, and the occurrence of a fire is detected, the housing police device The sound pressure measurement test of 10-1 is interrupted and a fire alarm sound indicating the interlocking destination is output.

  In addition to this, in the embodiment of FIG. 9, when the sound pressure measurement test of the home alarm device 10-1 is completed, the home alarm device 10-2 to 10-5 is compared with the other home alarm devices 10-2 to 10-5 according to a preset order. An event signal indicating the start of the sound pressure measurement test is transmitted from 10-1, and the sound pressure measurement test is remotely performed by the residential police device 10-3 as shown in FIG. 9A, for example.

  In this remote sound pressure measurement test, the order of the house alarm devices 10-2 to 10-5 performing the remote sound pressure test from the house alarm device 10-1 is determined in advance and notified to the measurement staff, For example, if it is known that the remote test of the home police device 10-3 will be the next after the test of the home police device 10-1 is completed, the test of the next home police device 10-3 is completed at the end of the test of the home police device 10-1. The inspector moves to the place and prepares by installing the sound level meter 26 as shown.

  Upon receiving the event signal indicating the start of the sound pressure measurement test from the home alarm device 10-1, the home alarm device 10-3 continuously outputs the sweep alarm sound that is the target of sound pressure measurement as the test sound 25. Also, the home alarm device 10-1 transmits an event signal indicating the end of the sound pressure measurement test after a predetermined time has elapsed, and the event signal is effectively received by the home alarm device 10-3 under test to end the sound pressure measurement test. Let Note that the end of the remote sound pressure measurement test may be ended upon detection of the elapse of a predetermined time by a timer provided in the test destination residence guard 10-3.

  During the continuous output of the test sound of the residential police device 10-3 by the remote sound pressure measurement test, for example, as shown in FIG. A fire event signal is sent to the alarm. When this fire event signal is effectively received by the residential alarm 10-3 during the sound pressure measurement test, the sound pressure measurement test is interrupted, and a fire alarm sound indicating the interlocking destination is output.

  As described above, when the sound pressure measurement test is executed by the alarm stop switch 20 for any one of the plurality of home alarm devices 10-1 to 10-5, the sound pressure of the home alarm device that has performed the operation is displayed. After the measurement test is completed, the sound pressure measurement test of other house alarms is performed remotely according to a predetermined order, and it is not necessary to perform the sound pressure execution operation by the alarm stop switch 20 for each house alarm. A sound pressure measurement test can be easily performed when a home alarm is installed.

  In addition, if the stop operation of the alarm stop switch 20 is determined in the home alarm device 10-1 that has instructed the remote test during the remote sound pressure measurement test of the home alarm device 10-3, the sound pressure measurement test is terminated. The event signal shown is transmitted, and the sound pressure measurement test started by the remote instruction can be stopped and stopped before the predetermined time elapses.

  The end of the remote sound pressure test is not limited to the home alarm device 10-1 that issued the remote test instruction, but also the alarm stop switch 20 provided in other home alarm devices including the home alarm device during the remote test. It may be possible even when the stop operation is determined.

  FIG. 10 is a block diagram showing an embodiment of the residential guard 10-1 corresponding to the second invention of the present application corresponding to the sound pressure measurement test by remote instruction of FIG. This is an example, and the separation and integration of each function can be performed arbitrarily. Each part or all of each function may be executed by software (program) or may be executed by hardware. Moreover, in FIG. 4, although it has shown about the residence guard 10-1 installed in the kitchen, it becomes the same structure also about the other residence guards 10-2 to 10-5.

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

  The processor 28 is provided with a monitoring control unit 58 as a function realized by executing the program. The monitoring control unit 58 includes an event detection unit 60, a transmission processing unit 62, a reception processing unit 64, an alarm process. The function of the unit 66 is included. The processor 28 is provided with functions of a test execution unit 68 and a test interruption unit 70 corresponding to the sound pressure measurement test. Details of the configuration and functions are basically the same as those in the embodiment of FIG.

  In addition to this, in the embodiment of FIG. 10, the processor 28 is provided with functions as a remote test instruction unit 72 and a remote test execution unit 74 corresponding to a remote sound pressure measurement test. The memory 32 stores in advance a remote test management table 76 in which a transmission source code indicating the order of remote tests is registered. The function of the remote test execution unit 74 may be included in the test execution unit 68 as one function.

  When the event detection unit 60 detects an instruction input by a long press operation of the alarm stop switch 20 in the normal monitoring state by the event detection unit 60, the test execution unit 68 detects the execution operation of the sound pressure measurement test and indicates the link source or link destination. Necessary for the sound pressure measurement test from the speaker 56 of the notification unit 36, where the test sound is the location of the sweep alarm sound “Woo Woo” that is the target of sound pressure measurement in the fire alarm sound of a predetermined pattern consisting of a combination of alarm sound and message A sound pressure measurement test is performed for repeated output over a predetermined time, for example, 1 minute. This is the same as in the embodiment of FIG. 4, and the sound pressure measurement test of the local police device 10-1 that gives a remote test instruction is executed.

  When the test execution unit 68 finishes the sound pressure measurement test of the home alarm device itself, the remote test instruction unit 72 transmits the home alarm device as the remote instruction destination according to the order registered in the remote test management table 76 of the memory 32. An event signal indicating the start of the sound pressure measurement trial including the original code is transmitted.

  When the remote test instructing unit 72 determines that the predetermined time required for the remote sound pressure measurement test has elapsed after transmitting the event signal indicating the start of the sound pressure measurement test, the remote test instruction source 72 transmits the transmission source code of the resident alarm device as the remote designation destination. An event signal indicating the end of the sound pressure measurement test including is transmitted to end the remote sound pressure measurement test. Here, as the predetermined time until the event signal indicating the end of the sound pressure measurement test is transmitted, sufficient time is required for the measurer to move to the place where the remote monitoring device to be remotely tested and install the sound level meter. Therefore, for example, 5 minutes is set.

  When the remote test instructing unit 72 determines that the operation of the alarm stop switch 20 is detected during the remote test, the remote test instruction unit 72 transmits an event signal indicating the end of the remote test execution to the other home alarm device to end the test remotely. It can also be made.

  When the remote test execution unit 74 detects the effective reception of the event signal indicating the start of the remote test from another house alarm, the fire test sound of a predetermined pattern consisting of a combination of an alarm sound indicating the link source or the link destination and a message is displayed. A sound pressure measurement test is performed in which the position of the sweep warning sound “Woo-woo” that is the object of sound pressure measurement is used as a test sound, and is repeatedly output from the speaker 56 of the notification unit 36.

  In addition, when the remote test execution unit 74 detects the effective reception of an event signal indicating the end of the remote test from another residential alarm device during the execution of the remote measurement test, the remote test execution unit 74 ends the remote sound pressure measurement test.

  When the remote test execution unit 74 determines effective reception of an event signal indicating the start of the remote test, it is preferable that the remote test execution unit 74 does not start the sound pressure measurement test immediately but starts the sound pressure measurement test after a predetermined delay time. As a result, when the time from the effective reception of the event signal indicating the start of the sound pressure test to the effective reception of the event signal indicating the end of the sound pressure measurement is, for example, 5 minutes, the remaining time is reduced by 4 minutes. The sound pressure measurement test is executed in 1 minute and the test sound is continuously output, and the first 4 minutes can be set as a preparation time necessary for the movement of the measurement staff and the installation of the sound level meter for the remote test. For this reason, even if the time interval for transmitting the event signal at the start and end of the sound pressure measurement test is set to 5 minutes, for example, the test sound is not continuously output during that time, and the measurement staff moves with the remote test. And remote testing of appropriate sound pressure measurement in consideration of preparation.

  During the sound pressure measurement test by the test execution unit 68 or the remote test execution unit 74, that is, during the continuous output of the sweep warning sound “Woo-woo” for a predetermined time, the test interruption unit 70 When the event detection unit 60 receives fire event signals from the other home alarm devices 10-2 to 10-5 effectively and detects a fire occurrence, the sweep alarm sound "Woo-woo" is continuously output from the speaker 56 as a test sound. The sound pressure measurement test is interrupted, and a fire alarm sound corresponding to the occurrence of a fire is output from the speaker 56.

FIG. 11 is an explanatory diagram schematically showing the event signal format used for the interlocking alarm in the present embodiment of FIG. This point is the same as in FIG. 5 except that the event code 54 corresponds to the remote sound pressure measurement test.
0111 = Sound pressure measurement test start 1000 = Sound pressure measurement test end is added.

  12 and 13 are flowcharts showing details of the sound pressure measurement process in the embodiment of FIG. 10, and correspond to the sound pressure measurement test process in step S19 of the main routine shown in FIG. The main routine in the embodiment of FIG. 10 is the same as that in FIGS.

  In FIG. 12, in step S30, the presence / absence of a sound pressure measurement test execution operation is detected. When a sound pressure measurement test execution operation is detected in step S30 by a long press operation of the alarm stop switch 20 in the normal monitoring state, the process proceeds to step S31, and a predetermined pattern of fire alarm sound indicating the interlock source or the interlock destination is displayed. The alarm sound signal of the sweep alarm sound “Woo-woo” is generated by the voice synthesis circuit and continuously output, and the sweep alarm sound is continuously output as the test sound from the speaker 56.
