Description

The present invention operates with a battery power source and outputs an alarm on its own when an abnormality such as a fire in its own monitoring area is detected and sends an alarm signal to the other alarm device to indicate the alarm. Type alarm and monitoring system.

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

  In such a house alarm, it operates with a battery power source, and is equipped with a sensor part for detecting a fire and an alarm part for alarming a fire in the house alarm, and when a fire is detected from a detection signal of the sensor part. The alarm unit outputs a fire alarm sound with a predetermined pattern, and it is easy to install and inexpensive because it can be used for fire monitoring and alarm notification without requiring a dedicated receiving facility. Yes, it has become widespread with the obligatory installation in ordinary houses.

  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 has also been proposed.

  In such an interlocking house alarm, when a fire is detected by the house alarm, the home alarm that detects the fire outputs, for example, “Woo Woo is a fire” and other house alarms. On the other hand, by receiving the interlock signal, other house alarms that are the target of interlocking output a fire alarm sound, for example, “Woo-Wood alarm has been activated”.

  Further, 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 necessary during that period. When battery life (remaining power 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. I have to.

  After the start of the output of the low battery failure alarm (after the battery voltage drop is detected), it is only necessary that intermittent low battery failure alarm output is possible for a predetermined time, for example, 72 hours or more. There is no problem if the battery is replaced in time. In general, the low battery failure alarm is more urgent than the alarm that reports abnormalities in the monitoring area, such as a fire alarm, because it is designed to allow normal fire monitoring operation during this period. It is not a high alarm. In other words, a low battery failure may be dealt with within, for example, 72 hours, but an immediate response is naturally required for a fire.

Furthermore, the wireless interlocking house alarm employs a radio signal intermittent reception system in order to reduce power consumption. In the intermittent reception method, a predetermined receivable time is set for each predetermined period, the receiving unit is operated to perform carrier sense, and when a reception output is obtained by carrier sense, the reception operation is continued and the interlocking signal is received. .

JP 2007-094719 A Utility Model Registration No. 3143139

  By the way, in such a conventional interlocking type home guard, when a fire or an event other than a fire is detected, a transmission operation that repeats transmission for a predetermined time multiple times with a predetermined pause time in accordance with a communication standard By transmitting the interlock signal intermittently multiple times, the fire alarm signal and the interlock signal other than the fire can be surely received by other house alarms that are receiving intermittently and the interlock alarm can be issued. Yes.

  However, the linkage when a fire is detected is more important than the linkage when an event other than a fire is detected, and it is necessary to transmit and receive more reliably without being affected by the radio wave environment. In the case of a house alarm, the same transmission / reception method is used for the interlocking of fire and the interlocking of events other than fire. Here, it is desirable to further improve the speed and certainty of transmission / reception at least for fire interlocking, which is highly important as described above.

  Also, in the conventional interlocking house alarm, when a fire is detected in a low battery failure state where the battery voltage is low, a fire alarm is generated by an alarm sound and an alarm display by itself. During this time, the transmission operation to transmit the interlock signal to other alarm devices and the intermittent reception operation to receive the interlock signal from other housing alarm devices during this period are also performed. By being performed together, the consumption of the battery is promoted, and the battery may run out during a fire alarm and may not function. For example, it may be impossible to continue the fire alarm (notification) as the interlock source, which has the highest necessity for the fire alarm output.

The present invention enhances the interlocking signal transmission function when an abnormality such as a fire is detected while the battery voltage is normal so that the interlocking operation can be performed quickly and reliably. When detecting abnormalities, such as monitoring alarms and monitoring systems that prioritize at least the maintenance of their own abnormal monitoring and alarm output (notification output) functions and minimize battery consumption related to other functions. The purpose is to provide.

The present invention is an alarm device that operates on a battery power source and transmits an interlocking signal indicating the detected event to another alarm device when an event including a predetermined abnormality is detected .
When an event other than the specified abnormality is detected, the transmission mode is set to the normal mode,
The battery voltage is higher Jo Tokoro level state, when detecting a predetermined abnormality is a high mode of transmission capability compared to normal mode transmission mode,
When the battery voltage is less than a predetermined level and a predetermined abnormality is detected, the transmission mode is set to a power saving mode compared to the normal mode .
It is characterized by that.

In addition, the present invention operates with a battery power source, and outputs a warning indicating a link source when a predetermined event is detected in a monitoring area and transmits a link signal indicating the predetermined event from another transmitter to another alarm device. In the alarm device that outputs an alarm indicating the interlocking destination when the interlocking signal indicating the predetermined event is received by the receiving unit from another alarm device,
The transmitter

Send
When the battery voltage is less than a predetermined level and a predetermined event is detected, a predetermined fourth transmission mode with lower power consumption than the third transmission mode is set and an interlocking signal is transmitted to another alarm device.
It is characterized by that.

  Here, when a predetermined event or other event is detected, the transmission unit repeats a predetermined transmission operation combining a predetermined pause time and a predetermined transmission time a plurality of times, and the first mode is a predetermined transmission. The second transmission mode sets the number of transmissions more than the first transmission mode, the third transmission mode sets the number of transmissions to be the same as or less than the first transmission mode, and the fourth transmission mode uses the transmission The number of times is set smaller than that in the third transmission mode.

  The second transmission mode further increases transmission power compared to the first transmission mode.

  In the second transmission mode, the transmission radio wave intensity is increased or the transmission frequency is increased as compared with the first transmission mode.

The receiver
When the battery voltage is equal to or higher than the predetermined level and an event other than the predetermined event is detected, a predetermined first reception mode is set and an interlocking signal is received from another alarm device,
When the battery voltage is equal to or higher than a predetermined level and a predetermined event is detected, a predetermined second reception mode that consumes less power than the first reception mode is set and an interlocking signal is received from another alarm device,
When an event other than a predetermined event is detected when the battery voltage is lower than a predetermined level, a predetermined third reception mode that is equal to or smaller than the power consumption of the first and second reception modes is set and interlocked with other alarm devices. Receive the signal,
When the battery voltage is less than a predetermined level and a predetermined event is detected, a predetermined fourth reception mode that consumes less power than the third reception mode is set and an interlocking signal from another alarm device is received or received. Stop.

The receiving unit performs intermittent reception for setting a predetermined receivable time for each predetermined period when a predetermined event or other event is not detected,
In the first reception mode, intermittent reception is switched to continuous reception while the event detection state continues, and is returned to intermittent reception before event detection on condition that the event detection state is canceled,
In the second reception mode, intermittent reception is switched to continuous reception during transmission in the second transmission mode, and is returned to intermittent reception before event detection after transmission ends, or intermittent power consumption is reduced during event occurrence after transmission ends. Switch to reception, return to intermittent reception before event detection on condition that the event detection state has been canceled,
In the third reception mode, intermittent reception is switched to continuous reception during transmission in the third transmission mode, and is returned to intermittent reception before event detection after transmission is completed.
In the fourth reception mode, intermittent reception is switched to continuous reception during transmission in the fourth transmission mode, and is switched to intermittent reception with reduced power consumption during the event detection state after the transmission ends, and the event detection state is released. To the intermittent reception before the event detection.

  The intermittent reception with reduced power consumption in the second reception mode and the fourth reception mode lengthens the predetermined period and / or shortens the predetermined receivable time.

When the receiver receives the interlock signal effectively from another alarm device, the transmitter transmits an ACK signal indicating normal reception,
After receiving the ACK signal from another alarm device after transmitting the interlock signal from the transmitter, and detecting the alarm device that does not receive the ACK signal, the interlock signal is sent to the other alarm device that has received the ACK signal. The interlocking signal including the code indicating the relay request is transmitted to the relay, and the contents of the interlocking signal are relayed and transmitted.

Send
When the battery voltage is less than a predetermined level and a predetermined event is detected, a predetermined fourth transmission mode with lower power consumption than the third transmission mode is set and an interlocking signal is transmitted to another alarm device.
It is characterized by that.

  According to the alarm device of the present invention, when a battery voltage is normal and an abnormality such as a fire in the monitoring area is detected as an interlock source, the first transmission mode for transmitting an interlock signal by detecting an event other than a fire is performed. On the other hand, the second transmission mode with high power consumption, for example, the second transmission mode in which the number of transmissions and transmission power is increased is set to transmit the fire interlocking signal, so that the function of transmitting the interlocking signal is enhanced. It is possible to quickly and surely transmit an interlocking signal accompanying detection of an abnormality such as a fire having a relatively high importance to another alarm device to issue an interlocking alarm, thereby improving the reliability of the interlocking alarm.

  In addition, high power transmission in the second transmission mode to enhance the transmission function promotes battery consumption. However, when an abnormality such as a fire is detected, an interlock signal from another alarm device is detected when an event other than a fire is detected. In order to set the second reception mode with low power consumption relative to the first reception mode for receiving the power consumption, the battery consumption increased due to high power consumption transmission based on its own fire detection is suppressed by the low power consumption reception performed simultaneously, The influence on the battery life can be reduced.

  In addition, according to the alarm device of the present invention, when a predetermined event indicating an abnormality such as a fire in the own monitoring area is detected as an interlock source in a low battery fault state in which the battery voltage is lowered, the alarm is detected by detecting an event other than a fire. Because the interlocking signal is transmitted by changing to the fourth transmission mode, which consumes less power than the third transmission mode for transmitting signals, the interlocking signal is transmitted to other alarm devices while an abnormal alarm such as a fire is being output as the interlocking source. By reducing the power consumption required for the battery and suppressing its own battery consumption in a low battery failure state, it is possible to maintain the power applied to the alarm output function such as a fire as a linkage source.

  In addition, when a low battery failure state in which the battery voltage has dropped and a predetermined event indicating an abnormality such as a fire is detected as a link source, a reception signal is also received from other alarm devices by detecting an event other than a fire. In order to change to the fourth reception mode, which consumes less power than the third reception mode for receiving, in addition to reducing the power consumption by the fourth transmission mode, the power consumption necessary for receiving the interlocking signal is also reduced, resulting in a low battery failure state. By further suppressing the consumption of a certain battery, it is possible to maintain power applied to an alarm output function such as a fire as a linkage source.

  Here, when an abnormal alarm such as a fire is output as an interlock source in a low battery failure state, the transmission time of the interlock signal is substantially shortened by, for example, the fourth transmission mode for reducing power consumption. There is a possibility that the interlocking function with other alarm devices may be impaired.

  However, for example, when a linked system is configured with three or more alarm devices (this is the case with a general house-linked home alarm system), there are multiple alarm devices that can be linked to one linked source. Therefore, even if the transmission time is shortened at the link source, the probability of being received by one of the two alarm devices is not so low as to be a big problem. At least, it is not a serious problem when compared with monitoring the abnormality as an interlocking source alarm device and maintaining the alarm output function. When each alarm device at the interlock destination can execute the relay function of the interlock signal, if it is received by one unit, it is relayed and transmitted sequentially, and all other alarm devices can perform the interlock destination alarm.

  In addition, the interlocking signals from other alarm devices are further relayed from other alarm devices, so the total number of transmissions increases. Even if intermittent reception is continued or the reception cycle is extended in the fourth reception mode in order to reduce the above, from the same viewpoint as described above, there is substantially no problem.

In addition, while the alarm device itself is in the middle of outputting an abnormal alarm such as a fire, it is less necessary to process the interlock signal from other alarm devices, so as a fourth reception mode to reduce power consumption, For example, even if the reception function is stopped as the lowest consumption pattern, there is substantially no problem from the same viewpoint as described above.

  FIG. 1 is an explanatory view showing an example of an installation state of a monitoring system using an interlocked house alarm which is an alarm device of the present invention for a house. In the example of FIG. 1, a wireless system that detects and interlocks with a fire in each of the warning areas (monitoring areas) of the kitchen, living room, children's room, master bedroom, and staircase provided in the house 24. House alarms (fire alarms for houses) 10-1 to 10-6 are installed. Hereinafter, the housing alarm devices 10-1 to 10-6 are collectively referred to as the housing alarm device 10 without being distinguished from each other.

  The home alarm device 10 has a function of wirelessly transmitting and receiving interlocking signals to each other, and monitors whether or not a fire has occurred in each corresponding monitoring area of each house. If a fire has occurred in the kitchen of the house 24, the home alarm device 10-1 detects the fire and starts an alarm. Detecting this fire and initiating an alarm is referred to as “reporting” at the home alarm.

  When the home alarm device 10-1 issues a report, the home alarm device 10-1 functions as an interlocking source, and wirelessly transmits a fire interlocking signal to the other interlocking devices 10-2 to 10-6 serving as interlocking destinations. To do. When the other home alarm devices 10-2 to 10-6 have received the fire interlock signal from the home alarm device 10-1 as the interlock source, the other home alarm devices 10-2 to 10-6 perform the alarm operation as the interlock destination by the alarm sound and the alarm display.

  Here, when the group code included in the received interlocking signal matches the group code registered in the memory and the signal content is normally recognized, the resident alarm 10 confirms that the interlocking signal has been effectively received. I try to detect it. Further, the interlocking signal transmitted from the home alarm device 10 includes a source code using, for example, a serial number as identification information indicating the source home alarm device. Furthermore, the resident guard 10 that has effectively received the interlocking signal relays the interlocking signal as necessary.

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

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

A protrusion is provided at the center of the cover 12, a plurality of smoke inlets are opened around the protrusion, and a smoke detector 16 is disposed in the inside thereof, so that smoke accompanying a fire passes through the inlet. The fire is detected when it reaches the specified concentration. As the smoke detector 16, a smoke detector mechanism such as a scattered light type smoke detector can be applied.

  An acoustic hole 18 is provided on the lower left side of the cover 12, and a buzzer and a speaker are incorporated behind this so that an alarm sound and a voice message can be output. An alarm stop switch 20 is provided below the cover 12.

  The alarm stop switch 20 is configured to press a built-in push switch (not shown) when a switch cover formed of a translucent member is pressed. An LED 22 for displaying an alarm or the like is disposed near the push switch inside the switch cover.

  Further, a mounting hook 15 having an insertion hole in the substantially central portion thereof is provided at the upper part on the back side of the main body 14, and a screw or the like is screwed into the wall of the 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 in a so-called wall-hanging manner.

  FIG. 3 is a block diagram showing the configuration of the main part of the residence guard 10-1 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. 3, 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 10-6.

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

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

  Of course, when the wireless communication unit 30 is used outside Japan, the wireless communication unit 30 has contents compliant with the standard of the assigned wireless station in that region.

  Here, the antenna 31, the transmission circuit 42, and the transmission control unit 62 function as a transmission unit, and the antenna 31, the reception circuit 44, and the reception control unit 64 function as a reception unit.

In the memory 32, a serial number 48, which is a serial number indicating the generation order or transmission order of the interlocking signal, a transmission source code 50 using, for example, a serial number or the like serving as residential alarm identification information for identifying each residential alarm, The group code | symbol 52 for comprising the interlocking | linkage group which performs an interlocking | linkage alarm with each residence alarm device 10 installed in the house 24 like 1 is stored.

  The sensor unit 34 is provided with a smoke detection unit 16 that observes (detects) smoke according to the scattered light type smoke detection principle and outputs a detection signal corresponding to the smoke density.

The notification unit 36 is provided with a speaker 56 that is an acoustic output device that outputs an alarm sound and the like, and an LED 22 that displays an alarm. The speaker 56 is driven by a drive circuit (not shown) based on various data stored in the memory or the like by the control of the alarm processing unit 60 to be described later, so that a voice message, an alarm sound, etc. Is output. Similarly, the LED 22 driven by a display driving circuit (not shown) displays an abnormality such as a fire by blinking, blinking, or lighting.

  The operation unit 38 is provided with an alarm stop switch 20, and the alarm stop switch 20 also functions as an inspection switch for instructing self-inspection of the function of the home alarm device 10-1. For example, when the alarm stop switch 20 is operated while a fire alarm is being output by a user or the like, the fire alarm is stopped, and when the alarm stop switch 20 is operated in a normal state, a predetermined function check is performed and the result is notified. . Here, the normal state refers to a state where at least a fire alarm is being output or a failure alarm is not being output.

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

  The processor 28 is provided with functions of an alarm processing unit 60, a transmission control unit 62, and a reception control unit 64 as functions realized by executing the program.

  The alarm processing unit 60 is provided with the presence or absence of a fire based on the detection signal output from the smoke detector 16 provided in the sensor unit 34, the presence or absence of an alarm stop instruction input by the operation of the operation unit 38, the presence or absence of an inspection instruction input, In addition to the presence or absence of a fire recovery that reduces the detection signal output from the smoke detector 16 provided to eliminate the fire detection state, the presence or absence of sensor failure or low battery failure via various monitoring circuits (not shown) as necessary Detect events such as. Further, the alarm processing unit 60 detects the presence / absence of the interlocking signal effective reception obtained as a result of decoding the interlocking signals from the other dwelling devices 10-2 to 10-6 and the interlocking contents via the receiving unit.

In addition, when the alarm processing unit 60 detects a fire based on the smoke detection signal of the smoke detecting unit 16 provided in the sensor unit 34, the alarm processing unit 60 issues an alarm sound indicating the interlock source from the speaker 56 to the notification unit 36, for example, “Woo Woo Fire “Please confirm” voice message is repeatedly output, control is performed to turn on the LED 22 and display an alarm indicating the interlocking source, and further fires via the transmission control unit 62 and the transmission circuit 42 The interlocking signal is transmitted from the antenna 31 to the other residential alarm devices 10-2 to 10-6.

  In addition, the alarm processing unit 60 has detected that the fire-linked signal has been effectively received from any of the other residential alarm devices 10-2 to 10-6 via the reception circuit 44 and the reception control unit 64 of the wireless communication unit 30. In this case, an alarm sound indicating the interlocking destination, for example, “Wow, please confirm that another fire alarm has been activated” is repeatedly output from the speaker 56 of the notification unit 36 and the LED 22 is blinked, for example. An alarm display showing is displayed.

  When the alarm processing unit 60 detects the operation of the alarm stop switch 20 during the output of the fire alarm sound indicating the interlocking source, the alarm processing unit 60 controls the notification unit 36 to fire the alarm by the voice message from the speaker 56 and the alarm display of the LED 22. The output of is stopped. In addition, when the effective reception of the alarm stop interlocking signal from any of the other residential alarm devices 10-2 to 10-6 is detected during the output of the fire alarm sound indicating the interlock source, the fire alarm is not stopped and interlocked Try to understand the origin.

  Further, the alarm processing unit 60 detects the operation of the alarm stop switch 20 or the effective reception of the alarm stop interlocking signal from any of the other residential alarm devices 10-2 to 10-6 during the output of the alarm sound indicating the interlock destination. When it does, the alerting | reporting part 36 is controlled and the output of the fire alarm by the voice message from the speaker 56 and the alarm display of LED22 is stopped.

The alarm processing unit 60 is provided with a low battery failure monitoring function in which the battery voltage of the battery power supply 40 is less than a predetermined level, and is automatically executed regularly in the background as a built-in test.

  Specifically, the low battery fault monitoring is a built-in that reads a battery voltage supplied from the battery power supply 40 at a predetermined measurement time interval, for example, a 4-hour interval via a voltage monitoring circuit (not shown), and compares it with a predetermined threshold voltage. A test is performed, and when the battery voltage is lower than the threshold voltage, the low battery failure is preliminarily determined, and the result is counted and stored. Further, when the low battery failure preliminary determination continues continuously for a predetermined number of times, the low battery failure is determined (confirmed). The low battery failure flag is set and updated and stored in the memory 32.

  The alarm processing unit 60 is provided with a sensor failure monitoring function for monitoring a failure of the sensor unit 34, and is automatically executed in the background as a built-in test. Specifically, the sensor failure monitoring reads a smoke detection signal output from the smoke detector 16 of the sensor unit 34 at a predetermined measurement time interval, for example, 1 second, and holds it in the memory 32. For example, every 10 minutes, the average value of the detected data for the last 10 minutes held in the memory 32 is obtained, and when this average value falls below a predetermined reference level (referred to as the zero point level), the output is stopped. For example, it is determined that the sensor unit 34 has failed, and a sensor failure flag is set and stored in the memory 32.

  When the alarm processing unit 60 detects an inspection instruction operation (inspection instruction input) by operating the alarm stop switch 20 that functions as an inspection switch in a normal state, the low battery failure flag or the sensor failure flag is set and stored in the memory 32. When it is determined and detected that the low battery failure alarm or the sensor failure alarm is output from the notification unit 36, the low battery failure interlocking signal or the sensor failure interlocking signal is output to the other residential alarm devices 10-2 to 10-10. Transmit to -6 to output a low battery fault alarm or sensor fault alarm indicating the fault linkage destination.

  In the transmission control unit 62, the fire detection based on the detection signal from the smoke detecting unit 16 by the alarm processing unit 60, the alarm stop input and inspection instruction input by the operation unit 38, and the detection detection signal output from the smoke detecting unit 16 are reduced. When a self-event such as a low battery failure or a sensor failure is detected, such as a fire recovery when the fire detection state is resolved, an interlocking signal indicating the detected event content is sent to the transmission circuit 42 and the antenna 31 of the wireless communication unit 30. And send it to the linked home alarm. Further, the transmission control unit 62 relays and transmits the interlocking signal that is effectively received from the other home guards as necessary.

  The reception control unit 64 receives and decodes the interlocking signals from the other mortgages 10-2 to 10-6 via the antenna 31 and the reception circuit 44 of the wireless communication unit 30. In addition, the reception control unit 64 has normally received the interlocking signal from the other residential alarm devices 10-2 to 10-6 while transmitting the interlocking signal to the other residential alarm devices 10-2 to 10-6. It is monitored whether or not an acknowledgment signal (hereinafter, referred to as “ACK signal”) indicating that is effectively received.

  When it detects that no other ACK signal is received (cannot confirm the reply of ACK signal) among other house alarms, there is a relay request from other house alarms for which ACK signal has been confirmed to be received by transmission control unit 62 A link signal (referred to as a link signal with a relay request) is transmitted, and a link signal with a relay request is received from an ACK response-confirmed home alarm device that has not yet responded to an AKC signal. Is relayed. The AK that has not received an AKC signal that has received the interlocked signal relayed here performs an alarm process or the like based on this reception and returns an ACK signal. It is received by the interlocking home security device 10-1.

  Here, in the transmission control unit 62 and the reception control unit 64 of the present embodiment, for each of the normal case where the battery voltage is above a predetermined level and the low battery failure state where the battery voltage has dropped below the predetermined level, The transmission mode and reception mode with different power consumption are set separately when an event other than a fire is detected and when a fire is detected.

  FIG. 4 is an explanatory diagram showing a list of magnitude relations between transmission / reception mode allocation and transmission / reception power consumption in each mode according to the present invention.

  FIG. 4A shows a transmission / reception mode assignment list according to the present invention, in which the following four transmission / reception modes are set. First, the transmission mode is the following first to fourth transmission modes.

(First transmission mode)
Set when the battery voltage is normal at a specified level or higher and an internal event other than a fire is detected.

(Second transmission mode)
It is set when the battery voltage is normal at a predetermined level or higher and the self detects a fire, and the power consumption is made larger than in the first transmission mode. That is, although the power consumption is higher than that in the first transmission mode, for example, the transmission radio wave intensity and the transmission frequency are increased or the number of transmissions is increased as compared with the first transmission mode, for example, for more reliable linkage.

(Third transmission mode)
It is set when a low battery failure state in which the battery voltage is less than a predetermined level and an in-self event other than a fire is detected, and the power consumption is the same or smaller than that in the first transmission mode. That is, for example, the transmission radio wave intensity, the transmission frequency, or the number of transmissions is set to be equal to or lower than the first transmission mode. If these are set lower than in the first transmission mode, at least for interlocking signal transmissions other than fire, power consumption in a low battery fault state can be suppressed as compared with a normal battery voltage state. The time from the state in which the remaining capacity is reduced until the power is finally cut off due to battery exhaustion is made as long as possible.

(4th transmission mode)
This is set when the battery voltage is less than a predetermined level and the battery itself is in a fault state, and when the self detects a fire, and consumes less power than in the third transmission mode. That is, for example, the transmission radio wave intensity, the transmission frequency, and the number of transmissions are set lower than those in the third transmission mode.

  The magnitude relationship of the transmission power consumption in the first to fourth transmission modes is summarized in FIG. 4B.

  On the other hand, the reception modes are the following first to fourth reception modes.

(First reception mode)
Set when the battery voltage is normal at a specified level or higher and an internal event other than a fire is detected.

(Second reception mode)
It is set when the battery voltage is normal at a predetermined level or higher and when the self detects a fire, and the power consumption is smaller than in the first reception mode. That is, for example, as compared with the first reception mode, the driving time of the receiving amplifier of the receiving circuit is shortened or the driving frequency is reduced.

(Third reception mode)
This is set when the battery voltage is lower than a predetermined level and the battery detects that an event other than a fire has occurred, and the power consumption is the same as or smaller than that in the second reception mode. That is, for example, the driving time of the receiving amplifier of the receiving circuit is made the same as or shorter than that in the second receiving mode, or the driving frequency of the receiving amplifier is made the same as or lower than that in the second receiving mode. When the driving time of the receiving amplifier is shorter than that in the second receiving mode and the driving frequency of the receiving amplifier is lowered, the power consumption in the low battery fault state is reduced for the reception of the interlock signal compared to the normal battery voltage state. In this way, the time from the state where the remaining capacity of the power supply has already been reduced to the time when the power supply is finally cut off due to battery exhaustion is made as long as possible.

(4th reception mode)
This is set when the battery voltage is lower than a predetermined level and when the battery detects a fire, and the power consumption is smaller than in the third reception mode. That is, for example, the driving time of the receiving amplifier of the receiving circuit is shortened or the driving frequency is reduced as compared with the third receiving mode.

  The magnitude relationship of the transmission power consumption in the first to fourth transmission modes is summarized in FIG. 4C.

  The operations in the first to fourth transmission modes and the first to fourth reception modes will be specifically described as shown in FIGS. In the following description, the case where the home alarm device 10-1 is the interlocking source and the home alarm devices 10-2 to 10-6 are the interlocking destination will be described as an example.

  FIG. 5 is a time chart showing transmission / reception control (or transmission / reception operation as a transmission / reception control result) in the first transmission mode and the first reception mode according to the present invention when an event other than a fire is detected in a normal state of the battery voltage. .

  In the first transmission mode, as shown in FIG. 5A, when an event other than a fire is detected at time t1, as shown in FIG. 5B, a predetermined time T1, for example, T1 = 3 seconds is applied. The transmission operation 70 for transmitting the interlocking signal is repeated, for example, four times with a pause of a predetermined time T2, for example, T2 = 2 seconds. This T1 = 3-second transmission and T = 2-second pause comply with the standard of a specific low-power radio station.

  The transmission operation 70 for T1 = 3 seconds is a dummy signal transmission operation 72 for 2.8 seconds from the beginning of the transmission operation 70, and the interlocking signal repeated transmission operation 74 is performed for the remaining 0.2 seconds. Yes. The dummy signal is detected by the intermittent sensing carrier sense in the other residential alarm device, and the reception operation is started, and the subsequent interlocking signal can be received.

  The first reception mode is performed as shown in FIG. 5C when an event other than a fire is detected at time t1 in FIG. Here, the reception control unit 64 performs intermittent reception in a normal state where neither a fire nor an event other than a fire is detected.

  As shown before the event occurs at time t1 in FIG. 5C, the intermittent reception repeats the reception operation during the receivable time T4 every period T3. For example, the period T3 = 7 seconds and the receivable time T4. = 100 milliseconds. When a transmission dummy signal from another resident alarm is detected by carrier sense during the receivable time T4, the reception signal is switched to the constant reception for a predetermined time and the interlocking signal following the dummy signal is received.

  The first reception mode is set when an event other than a fire is detected at time t1 in FIG. 5 (A), and the intermittent reception of the period T3 up to that time is switched to the continuous reception operation 80. ACK signal etc. can be received promptly. The constant reception operation 80 is continued during the occurrence of an event (during the duration of the event detection state), and when the event occurrence ends (when the detection state is released), the reception is returned to the intermittent reception before the event detection.

  Here, the constant reception operation 80 has the same transmission / reception channel frequency with respect to the transmission time T1 of the transmission operation 70 performed in parallel. The portion corresponding to T2 and the portion after the end of transmission are used as an effective reception operation 82.

  FIG. 6 is a time chart showing the second transmission mode and the second reception mode (or transmission / reception operation as a transmission / reception control result) according to the present invention when a fire is detected in a normal state of the battery voltage.

  In the second transmission mode, when a fire is detected at time t1 in FIG. 6A, the transmission operation 70 for transmitting the interlocking signal over T1 = 3 seconds is performed, for example, with a pause time of T2 = 2 seconds. Repeat once. In the second transmission mode, the number of transmissions is increased twice compared to the first transmission mode in FIG. 5 (B), so that the transmission function for the other residential alarm devices 10-2 to 10-6 is improved, and the fire-linked signal Transmission can be performed quickly and reliably, and a fire alarm can be issued also in other residential alarms.

  As the second transmission mode set by the transmission control unit 62, the transmission power may be increased in addition to this, and the transmission frequency may be increased by shortening the transmission cycle in accordance with this. As a result, the transmission function for the other residential alarm devices 10-2 to 10-6 is improved in the same manner, and the fire interlock signal can be transmitted promptly and reliably to issue a fire interlock alarm from the other residential alarm devices. it can.

  The second reception mode is, for example, any one of the low power consumption modes shown in FIGS. The second reception mode in FIG. 6C corresponds to the transmission operation 70 in FIG. 6A when a fire is detected at time t1, and the intermittent reception until then is switched to the constant reception operation 80. The reception operation 80 does not correspond to the occurrence of an event (event detection state duration), but continues during this time in response to a series of transmission processing periods due to the repetition of the transmission operation 70, and the transmission operation 70 is repeated at time t2. After the completion, it returns to intermittent reception before event detection.

  Here, as in FIG. 5C, the constant reception operation 80 has the same transmission / reception channel frequency, and the transmission time T1 of the transmission operation 70 performed in parallel is an interlocking signal from another resident alarm. Can not be received, the portion corresponding to the suspension time T2 is set as the effective reception operation 82, and the ACK signal or the like can be received from the other mortgages 10-2 to 10-6.

  In the second reception mode of FIG. 6 (C), since the continuous reception operation 80 is returned to the intermittent reception at the end of the transmission operation, the reception is always performed until the event occurrence end (event detection state cancellation) in the first reception mode of FIG. 5 (C). Compared with the case where the operation 80 is continued, the time of the constant reception operation 80 is shortened, and accordingly, the power consumption can be reduced, and the power consumption increased by the setting of the second transmission mode can be offset or suppressed. .

  The event detection state generally continues for a longer period than the transmission repetition period, but the duration of the event detection state may be shorter than the transmission operation repetition period. Even in this case, since the continuous reception operation is performed only during the corresponding period at least during the repeated transmission period, it is possible to suppress power consumption when the event detection state is equal to or longer than the transmission repetition period, as compared with the first reception mode. .

  In the second reception mode of FIG. 6D, as in FIG. 6C, the continuous reception operation 80 corresponding to the transmission mode of FIG. 6A is performed, and the intermittent reception after this is completed until time t1. Switching to intermittent reception with reduced power consumption compared to intermittent reception.

  That is, the intermittent reception period T3 from time t2 to intermittent reception with a period T5 shorter than that from time t2, and the receivable time T6 for each reception period T5 is set to the intermittent reception operation time to time t1. It is shorter than T4 and further reduces power consumption compared to FIG. This intermittent reception returns to the intermittent reception before the event detection (operation before t1) when the fire detection state is canceled due to fire recovery or the like. It should be noted that increasing the period of intermittent reception and shortening the receivable time may be either one in addition to both.

  Even when the second reception mode for reducing the power consumption is set in this way, the interlocking signals from the other home alarm devices 10-2 to 10-6 are further relayed from other home alarm devices as necessary. As a result, the number of transmissions exceeding a predetermined value is ensured, so the time of the continuous reception operation is shortened by setting the second reception mode, the reception cycle of intermittent reception is lengthened, or the receivable time is shortened. Even if the reception function is lowered, it does not substantially become a big problem.

  Also, while the alarm device 10-1 itself is in the middle of outputting an abnormal alarm such as a fire, it is less necessary to process the interlock signal from the other alarm devices 10-2 to 10-6, so the reception function is lowered. It doesn't really matter if you let it.

  6C and 6D, when the transmission operation 70 ends at time t2, the constant reception operation 80 is returned to the intermittent reception before the event detection. When the transmission operation 70 is completed at time t2 to receive an ACK signal or the like for the interlocking signal transmitted to the other home alarm at the end, the continuous reception operation 80 is changed to the event after the pause time T2 = 2 seconds. You may make it return to the intermittent reception before a detection.

  FIG. 7 is a time chart showing a third transmission mode and a third reception mode (or transmission / reception operation as a transmission / reception control result) according to the present invention when an event other than a fire is detected in a low battery failure state.

  In the third transmission mode, as shown in FIG. 7A, if an event other than a fire is detected at time t1, an interlocking signal is transmitted over T1 = 3 seconds as shown in FIG. 7B. The transmission operation 70 is repeated, for example, four times with a pause time of T2 = 2 seconds, and this embodiment is the same as the first transmission mode in FIG. Note that, for example, the transmission power consumption may be reduced by making the number of transmissions in the third transmission mode less than in the first transmission mode.

  The third reception mode is set when an event other than a fire is detected at time t1 in FIG. 7A, and the intermittent reception of the period T3 until then is switched to the regular reception operation 80. ACK signal etc. can be received promptly. The constant reception operation 80 is terminated when T2 = 2 seconds for receiving an ACK signal or the like has elapsed after the repetition processing of the transmission operation 70 is completed at time t2, and returns to intermittent reception before event detection.

  In addition, the reception of the ACK signal or the like when the interlocking signal is transmitted to another house alarm by the transmission operation 70 is normally completed until the fourth transmission operation 70 is performed if there is no problem in the communication environment. When the transmission operation 70 ends at time t2, the constant reception operation 80 may be returned to intermittent reception before event detection.

  Here, the constant reception operation 80 has the same transmission / reception channel frequency during the transmission time T1 of the transmission operation 70 performed in parallel. The portion corresponding to the time T2 and the time T2 after the end of transmission are set as the effective reception operation 82, and reception of ACK signals and the like from the other residential alarm devices 10-2 to 10-6 is enabled.

  The third reception mode is a constant reception time 80 corresponding to the number of transmissions of four in the third transmission mode, and the constant reception time of the second reception mode corresponding to the number of transmissions of six in the second transmission mode shown in FIG. Therefore, the power consumption can be reduced as compared with the second reception mode.

  FIG. 8 is a time chart showing the fourth transmission mode and the fourth reception mode (or transmission / reception operation as a transmission / reception control result) according to the present invention when a fire is detected in a low battery failure state.

  In the second transmission mode, as shown in FIG. 8 (A), if a fire is detected at time t1, a transmission operation 70 for transmitting an interlocking signal over T1 = 3 seconds as shown in FIG. 8 (B). Is repeated twice, for example, with a pause of T2 = 2 seconds, and power consumption is reduced by reducing the number of repetitions of the four transmission operations 70 in the third transmission mode in FIG. 7B. Yes.

Here, by the substantially shorten the transmission time of a fire interlock signal by the fourth transmission mode to reduce power consumption in a low battery state, is considered possible that interworking with other Ju警 unit is impaired .

However, when configuring the interlocking system for example six in home alarm 10-1 to 10-6 as shown in FIG. 1, Ju警 device comprising a linkage destination candidates with respect to a single interlocking source five Therefore, even if the transmission time is shortened in the interlocking home police 10-1, the probability of being received by any of the remaining five residential policers 10-2 to 10-6 is not so low as to be a big problem. .

  Also, if the ACK signal is not effectively received from any of the interlocking home police 10-2 to 10-6, a fire interlock signal with a relay request is transmitted and relayed to the home police that has confirmed the ACK response If it is received by one of these ACK response confirmed home relays, it is relayed and transmitted to all other home police devices 10-2 to 10-6. .

  The fourth reception mode is, for example, one of the three fourth reception modes shown in FIGS.

  FIG. 8C shows a time t2 for setting the constant reception operation 80 during the transmission processing period in the fourth transmission mode, which is the repetition of the two transmission operations 70 of FIG. 8B, and receiving an ACK signal or the like. After the transmission is completed, the reception is returned to the intermittent reception before the event detection after the elapse of T2, and the third reception is always completed after the elapse of T2 from the end of the four transmission operations 70 shown in FIG. 7C. Power consumption can be reduced compared to the mode.

  In addition, the reception of the ACK signal or the like when the interlocking signal is transmitted to another house alarm by the transmission operation 70 is normally completed until the second transmission operation 70 is performed if there is no problem in the communication environment. When the transmission operation 70 ends at time t2, the constant reception operation 80 may be returned to intermittent reception before event detection. This also applies to FIG. 8D described later.

  8D corresponds to the fourth transmission mode in FIG. 8B, and after the continuous reception operation 80 similar to FIG. 8C is completed, intermittent reception with lower power consumption than before t1 is set. doing. That is, after T2 time has elapsed from the transmission end time t2, intermittent reception with a period T4 shorter than the intermittent reception period T3 up to time t1, and further, the receivable time T6 for each reception period T4 is set to the time Switching to intermittent reception shorter than the operable time T5 of intermittent reception until t1. This intermittent reception returns to the intermittent reception before the event detection (operation before t1) when the fire detection state is canceled due to fire recovery or the like. It should be noted that increasing the period of intermittent reception and shortening the receivable time may be either one in addition to both.

  In FIG. 8E, when a fire is detected at time t1, the intermittent reception up to that time has been switched to reception stop 90, and the reception stop 90 detects an event when the fire detection state is canceled, such as when a fire recovery is detected. Return to the previous intermittent reception. The power consumption can be significantly reduced by the reception stop 90 during the fire detection.

  Even when the fourth reception mode is set in order to reduce power consumption, the number of transmissions of the interlocking signals from the other home alarm devices 10-2 to 10-6 is relayed from the other home alarm devices. Therefore, even if the continuous reception time is shortened, the intermittent reception period is shortened, or the receivable time is shortened by setting the second reception mode, there is substantially no problem.

In addition, when the reception is stopped, it becomes impossible to receive the interlock signal from the other residence guards 10-2 to 10-6. However, while the residence guard 10-1 itself is outputting the malfunction alarm such as a fire, etc. is low the need to process the interlock signal from Ju警 device 10 @ -2 to 10 @ -6, and is substantially even stops receiving function no problem.

  In addition to the above, as the second reception mode, the third reception mode, and the fourth reception mode, the reception operation corresponding to the constant reception 80 in FIGS. 6 to 8 is also set to an appropriate intermittent operation, or the transmission operation 70 is repeated. The reception operation may be stopped during a period during which the fire detection state is continued or during which a suitable delay time is added thereto.

  In addition, as a non-fire event, if a fire is detected in the low battery failure undetected state and transmission / reception in the second transmission mode and the second reception mode is performed and then a fire recovery or alarm stop is detected, the first transmission mode To send a fire recovery interlock signal and alarm stop interlock signal, and switch to the normal reception operation in the first reception mode, and receive an ACK signal from other resident alarms for the fire recovery interlock signal and the alarm stop interlock signal. When signal reception is confirmed, and when an appropriate delay time has passed after confirming the ACK signal, if necessary, the intermittent reception before fire detection is restored.

  In other words, when the fire recovers, it does not immediately return to intermittent reception before the fire detection, but during that time, the transmission of the fire recovery interlock signal and alarm stop interlock signal in the first transmission mode and the first reception mode and the ACK signal After receiving, it returns to intermittent reception before fire detection. That is, for example, event detection state cancellation such as fire restoration is an event other than a fire.

  In addition, as a non-fire event, if a fire is detected in the low battery failure detection state and a fire recovery or alarm stop is detected after transmission / reception in the fourth transmission mode and fourth reception mode, the third transmission mode Sends a fire recovery interlock signal and alarm stop interlock signal and switches to the continuous reception operation in the third reception mode, and receives an ACK signal from another resident alarm for the fire recovery interlock signal and the alarm stop interlock signal, and the ACK signal When reception is confirmed, and when an appropriate delay time has passed after confirming the ACK signal, if necessary, the reception is returned to the intermittent reception before the fire detection.

  FIG. 9 is an explanatory diagram schematically showing the format of the interlocking signal used for the interlocking alarm in this embodiment. In FIG. 9, the interlocking signal 46 includes a serial number 48, a transmission source code 50, a group code 52, and an event code 54. It should be noted that both the link source transmission source code and its own transmission source code as the relay transmission source are added to the link transmission signal for relay transmission. If necessary, a code indicating that there is a relay request is added separately.

Here, the event code 54 is a code representing the content of an event such as a fire, and in the present embodiment, a 4-bit code is used. For example, 0001 = fire 0010 = ACK
0011 = Alarm stop 0100 = Recovery 0101 = Sensor failure 0110 = Low battery failure.

  FIG. 10 is a flowchart showing a schematic example of transmission / reception control in the house alarm of the present invention. In FIG. 10, the transmission / reception control sets the intermittent reception of the receivable time T4 in the cycle T3 in step S1, and then detects the presence or absence of a low battery failure in step S2.

  If it is detected in step S2 that there is no low battery failure (normal battery voltage), the process proceeds to step S3. If an event other than a fire is detected in step S3, the process proceeds to step S4, and the first transmission mode illustrated in FIG. The first reception mode shown in FIG. 5C is set. Subsequently, in step S5, the presence or absence of an event that has occurred (including recovery) is detected. When the event end is detected, the process returns to step S1 to set intermittent reception before event detection.

  If an event other than a fire is not detected in step S3, the process proceeds to step S6. If a fire is detected in step S6, the second transmission mode illustrated in FIG. 6B is set in step S7, and FIGS. One of the second reception modes illustrated in (D) is set. Subsequently, in step S8, the presence / absence of a fire state release such as a fire recovery is detected. When the fire state release is detected, the process returns to step S1 to set the intermittent reception before the event detection.

  On the other hand, if a low battery failure is detected in step S2, the process proceeds to step S9. If an event other than a fire is detected in step S9, the process proceeds to step S10, and the third transmission mode illustrated in FIG. The third reception mode shown in C) is set. Subsequently, in step S11, the presence or absence of an event that has occurred (including recovery) is detected, and when event end is detected, the process returns to step S1 to set intermittent reception before event detection.

  If no event other than a fire is detected in step S9, the process proceeds to step S12. If a fire is detected in step S12, the fourth transmission mode illustrated in FIG. 8B is set in step S13, and FIGS. One of the fourth reception modes illustrated in (D) is set. Subsequently, in step S14, the presence or absence of a fire state release such as a fire recovery is detected. When the fire state release is detected, the process returns to step S1 to set intermittent reception before the event detection.

  FIG. 11 is a flowchart showing a schematic example of the monitoring process of the house alarm according to the present invention. In FIG. 11, 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 setting of transmission / reception mode are executed in step S21. Proceeding to S22, the presence or absence of a fire is detected. If there is an initialization abnormality in step S21, the information is notified from the notification unit 36 and the operation is stopped halfway, or the processing of step S11 is performed again, but the illustration is omitted. .

  In step S22, when the smoke detection signal output from the smoke detector 16 provided in the sensor unit 34 exceeds a predetermined fire level, a fire is detected and the process proceeds to step S23, and the fire-linked signal is wirelessly transmitted to other residential alarms. In addition to the transmission, a fire alarm indicating an interlocking source is output from the speaker 56 of the notification unit 36 by an alarm sound by a voice message or the like and an alarm display by, for example, lighting of the LED 22.

  At this time, when the low battery failure is not detected, transmission of the fire-linked signal by the setting of the second reception mode and reception by the setting of the second reception mode are performed. In the low battery failure detection state, transmission / reception is performed by setting the fourth transmission mode and the fourth reception mode.

  Subsequently, in step S24, the presence or absence of a fire restoration in which the smoke detection signal from the smoke detecting section 16 is lowered to cancel the fire detection state is detected. While transmitting to a house alarm, the fire alarm which shows the interlocking origin by the alarm sound from the speaker 56 and lighting of LED22 is stopped. The alarm display by the LED 22 may be turned off after a predetermined time has elapsed since the alarm sound stopped.

  In this case, the fire recovery interlock signal transmission mode is the first transmission mode corresponding to the detection of an event other than a fire when the low battery failure is not detected because the output of the fire alarm is stopped when the fire recovery is detected. In addition, the reception mode of the interlocking signal from the other residential alarm is assumed to be the first reception mode. In the case of a low battery failure detection state, the transmission mode is set to the third transmission mode corresponding to the detection of an event other than a fire, and the reception mode of the interlocking signal from the other residential alarm is set to the third reception mode.

  Subsequently, in step S26, 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 process proceeds to step S27, where an alarm stop interlocking signal is transmitted to another house alarm device, and from the speaker 56. The alarm sound output indicating the link source is stopped, and the alarm display by turning on the LED 22 is turned off. The alarm display by the LED 22 may be turned off after a predetermined time has elapsed since the alarm sound stopped.

  In this case, the fire stop interlocking signal transmission mode is the first transmission mode corresponding to event detection other than fire when the low battery failure is not detected because the output of the fire alarm is stopped. Reception of the interlocking signal from the mortgage is in the first reception mode. In the case of a low battery failure detection state, the transmission mode is set to the third transmission mode corresponding to the detection of an event other than a fire, and the reception mode of the interlocking signal from the other residential alarm is set to the third reception mode.

  The reception mode when the recovery interlock signal transmission and the alarm stop interlock signal are transmitted in the low battery failure undetected state in steps S25 and S27 ends the second reception mode when the fire recovery or the alarm stop is detected during the fire continues. The first reception mode is received. When the reception mode is switched from the second reception mode to the first reception mode, an ACK signal or the like is received, and the reception of the ACK signal is confirmed. When an appropriate delay time has passed after the signal confirmation, the reception is returned to the intermittent reception before the fire detection.

  In addition, when the recovery interlock signal is transmitted and the alarm stop interlock signal is transmitted in the low battery failure detection state in steps S25 and S27, the fourth reception mode is terminated when a fire recovery or alarm stop is detected during the fire continues. The third reception mode is set, but when the reception mode is switched from the fourth reception mode to the third reception mode, an ACK signal or the like is received, and when the reception of the ACK signal is confirmed, the ACK signal is further received as necessary. When an appropriate delay time has passed after the signal confirmation, the reception is returned to the intermittent reception before the fire detection.

  Then, it progresses to step S28, and the presence or absence of the fire interlocking | linkage signal effective reception transmitted or relay-transmitted from the other residence police is detected. When the effective reception of the fire interlocking signal from another house alarm is detected, the process proceeds to step S29, where an alarm sound is output from the speaker 56 as a fire alarm indicating the interlocking destination, for example, an alarm display by blinking of the LED 22 is performed.

  Next, in step S30, the presence / absence of the effective reception of the fire recovery interlocking signal transmitted or relayed from another resident alarm is detected. When the effective reception of the fire recovery interlocking signal is detected, the process proceeds to step S31 and the interlock destination The alarm display by the alarm sound output from the speaker 56 and the blinking of the LED 22 is stopped as an alarm.

  Next, in step S32, it is detected whether or not an alarm stop interlocking signal is effectively received transmitted or relayed from another resident alarm. When the alarm stop interlocking signal is effectively received, the process proceeds to step S33 as the interlocking destination. The alarm sound output is stopped and the alarm display is also stopped.

  When an interlocking signal is received from another mortgage at step S28, step S30, or step S32, relay transmission is performed when the relay request code is included in the interlocking signal. However, illustration is omitted for simplicity. doing.

  In addition, although illustration is omitted, for example, the occurrence of a failure such as a low battery or a failure and other events other than the illustration are also monitored as appropriate. Is transmitted, and a corresponding interlocking signal is transmitted to another resident alarm. In addition, when an interlocking signal indicating these events is received from another resident alarm, corresponding processing such as notification as an interlocking destination is performed, and relaying transmission of the interlocking signal is performed as necessary.

  In addition, although said embodiment took the example of the residence alarm device which detects and alarms a fire as abnormality of a monitoring area | region, fire alarm devices other than a residence alarm device, a gas leak alarm device, a CO alarm device, The present invention can be similarly applied to an alarm system in which various types of alarm devices are arranged and an alarm system in which these various types of alarm devices are mixed.

  Moreover, the monitoring system using the alarm device of the present invention may include a conventional alarm device that does not partially include the transmission / reception mode switching function according to the present invention. Even in this case, the object of the present invention can be achieved at least partially as a whole.

  In addition, the residential alarm device 10-1 (and 10-2 to 10-6) in FIG. 3 includes a smoke detector 16, which detects smoke generated by a fire and detects a fire in the monitoring area. This is taken as an example of a type of home alarm (alarm), but in addition to this, a thermal home alarm (alarm) equipped with a temperature detection element such as a thermistor that detects heat associated with fire and other types of fire This also applies to residential alarms that detect environmental changes, alarms that detect gas leaks other than fires, various alarms that detect intruders, earthquakes, and other abnormalities (alarms), and combinations of these alarms. It is included in the object of the invention.

  In the above embodiment, an example in which the transmission / reception mode is switched when a fire is detected as a predetermined event has been shown. However, in an alarm device that targets other events as abnormal conditions, for example, a gas leak alarm is detected when the event is detected.
