Description

The present invention relates to an alarm system and an alarm device that detect and alarm an abnormality such as a fire, and wirelessly transmit a signal to another alarm device to output the alarm in an interlocked manner.

  Conventionally, residential alarm devices (hereinafter referred to as “residential alarms”) that detect and warn of abnormalities such as fires and gas leaks in homes have become widespread. There is also an increasing tendency to monitor the anomalies such as fires in each room by installing a vessel.

  In this way, when a plurality of house alarms are installed in a dwelling unit, if a person is in a room different from the room where the abnormality has occurred, a warning sound may not be heard and a disaster such as a fire may spread. For this reason, when the house alarm devices are connected to each other by wire and a fire is detected and alarmed by a certain house alarm device, an interlocking alarm that sends a signal to another house alarm device and simultaneously issues an alarm is made possible.

  However, there is a problem in that the cost of the connection between the resident alarms is high due to the necessity of wired work. This problem can be solved by using a wireless residence guard. In addition, with the recent reduction in power consumption of ICs for wireless circuits, even in an operation state in which signals can be received at all times in order to be able to receive signals from other home alarm devices, for example, more than 5 years can be put into practical use. The endurance of battery life is guaranteed, and the environment for practical use of wireless home alarms is getting ready.

  By the way, in the case of a wireless dwelling alarm, when forming a linked group for a plurality of alarms installed in one dwelling unit, a registration operation is performed to form the linked group at the time of factory shipment or dwelling unit installation. Yes. Registration using a radio signal is called, for example, notification registration.

  In this alarm registration, a plurality of alarm devices forming a group are placed on a work table, etc., one of the alarm devices is set as a registration transmission mode, the remaining alarm devices are set as a registration reception mode, and the registration transmission mode is set. The event signal including the transmission source code is transmitted from the alarm device, and this is received by the alarm device waiting for registration in the registration reception mode, and the transmission source code included in the received event signal is registered in the memory. . When the registration registration mode is set for all the alarm devices in order to complete the alarm registration, the transmission source codes of the alarm devices belonging to the same group are registered in all the alarm devices forming the group.

In the monitoring state after the alarm registration is completed, when an event signal due to an abnormality detection such as a fire is transmitted from one alarm device, the event signal is received by another residence alarm device and the source code is acquired. However, if it matches the registered transmission source registered in the memory, an alarm is issued, and if it is not registered in the memory, it is ignored and an interlocking alarm is issued only within the group.

On the other hand, in this type of home alarm, if a fault occurs in the home alarm during operation, a fault alarm is issued by an acoustic alarm and display. The fault alarm is issued by the faulty resident alarm device, and at the same time, the fault alarm is issued by transmitting an event signal of the fault occurrence to the other resident alarms.

  Examples of such a failure alarm include a low battery warning that is performed by detecting a decrease in battery voltage, a life warning that is performed when the life of a residential alarm is approaching, and an alarm that is detected when a failure is detected by an automatic test. Such a warning about a failure of the home alarm is not called an immediate warning unlike a fire alarm, and is hereinafter referred to as an emergency warning.

However, if an emergency warning such as a low battery warning is issued during nighttime sleep, sleep will be disturbed.Therefore, a clock function will be provided in the home alarm, and even if a battery voltage drop is detected during the nighttime time, an alarm will be issued. Instead, an alarm is issued during the daytime from the time information.

JP 2007-094719 A

  However, such a conventional alarm device has a clock function for generating time information in order to issue an emergency warning such as a low battery warning in the daytime time zone without issuing it in the nighttime sleep time zone. Therefore, it is necessary to provide a clock IC known as a real-time clock (RTC) for generating time information of year / month / day / hour / minute / second, and there is a problem that the circuit configuration becomes complicated and the cost increases accordingly.

The present invention relates to an alarm system and an alarm device in which the time information is distributed from a specific alarm device to another alarm device by utilizing the mutual communication function by the interlocking group so as to simplify the device configuration and reduce the cost. The purpose is to provide.

The flowchart which showed the detail of the slave time management process of step S16 of FIG.

  FIG. 1 is an explanatory view showing an embodiment of an alarm system according to the present invention installed in a house. In FIG. 1, residence guards 10-1 to 10-4 serving as alarms of the present embodiment are installed in a kitchen, a living room, a master bedroom, and a child room provided in a house 11, and are further built outdoors. The garage 15 is also provided with a residence guard 10-5.

  Each of the residential alarms 10-1 to 10-5 has a function of wirelessly transmitting and receiving event signals to each other, and one interlocking group is formed by the five residential alarms 10-1 to 10-5. Fire monitoring of the entire house. Formation of the interlocking group can be realized by arranging the alarm devices 10-1 to 10-5 at one place such as a work table at the time of factory shipment or when installing in the house 11.

  This notification registration work is performed by sequentially sending one of the residence alarm devices 10-1 to 10-5 as a registration transmission mode and transmitting a registration event signal to another residence in a standby state in the registration reception mode. The registration event signal is received by the alarm device, the transmission source code is acquired from the registration event signal, and the registration process is performed in the memory.

  Moreover, in the residence police device 10-1 to 10-5 of the present embodiment, one of them, for example, the residence police device 10-1 installed in the kitchen is replaced with a master residence police device 10 having a clock function. -1 and the remaining home alarm devices 10-2 to 10-5 are set to slave home alarm devices 10-2 to 10-5 having no clock function.

  In the following description, the residence police device 10-1 will be described as a master residence police device, and the remaining residence police devices 10-2 to 10-5 will be explained as slave residence police devices.

  The master home alarm device 10-1 has a clock function for generating time information. The master home alarm device 10-1 uses the generated time information by itself, and at the same time, the slave home alarm device 10-2 to 10-5 stores the time information for each predetermined period. Has been delivered to. For this reason, the slave home alarm devices 10-2 to 10-5 do not have a clock function, and recognize the current time using the time information distributed from the master home alarm device 10-1.

  Each of the master home alarm devices 10-1 to 10-5 performs time management of the day time zone and the night time zone using the time information, and the low battery alarm and the home alarm device due to the battery voltage drop. When issuing an urgent alarm such as a life warning when the battery approaches the specified life, or a fault warning associated with an automatic test performed by a home alarm, the time information of the day or the night It is determined whether it is a time zone, and when it is a night time zone, for example, the time zone from 10 o'clock in the evening to 8 o'clock in the morning, it is suspended without issuing an emergency warning, and it is suspended in the daytime zone The time is managed so that an emergency warning is issued.

  Here, the master and slave are set to the home alarm device by setting the operation mode to the master or slave by using a dip switch or the like provided in the home alarm device.

  The clock function provided in the master home alarm 10-1 causes an error in the generated time information during use. The generated time information error is synchronized by using an accurate clock function provided in the intercom master unit 14 or the personal computer 16 installed in the house 11.

  For example, the interphone base unit 14 has an accurate clock function for displaying the time on the display, and the wireless transmission unit 14a additionally provided in the interphone base unit 14 with time information obtained by this clock function. Is transmitted to the master home alarm device 10-1, and time synchronization of the clock function provided in the master home alarm device 10-1 is performed.

  For the time synchronization of the master home alarm device 10-1, in addition to the interphone master unit 14, for example, the master home alarm device uses a wireless transmission unit 16a in which the time information generated by the personal computer 16 is added to the personal computer 16. The time may be synchronized by transmitting to 10-1.

  As for the wireless transmission units 14a and 16a provided in the interphone master unit 14 and the personal computer 16 used for this time synchronization, the same interlocking group as the master home alarm device 10-1 and the slave home alarm devices 10-2 to 10-5. The registration work is performed in advance so as to be included in.

  The time synchronization is performed by transmitting a time correction signal from the personal computer 16 to the master home alarm device 10-1 or all the home alarm devices via the slave home alarm device 10-2 installed in the same room. You can also

  Moreover, you may make it all the home alarms acquire the time information from the intercom main | base station 14, the personal computer 16, etc. separately, without distinguishing a master home alarm and a slave home alarm. At this time, as long as there is only one time information provider, time information from a device outside the group may be used.

  FIG. 2 is an explanatory view showing the appearance of the house alarm device according to the present invention installed in the house of FIG. 1, in which FIG. 2 (A) shows a front view and FIG. 2 (B) shows a side view. In FIG. 2, the residential alarm 10 of the present embodiment includes a cover 18 and a main body 20. In the center of the cover 18, a smoke detector 22 having a smoke inlet is opened around it so that a fire is detected when smoke from the fire reaches a predetermined concentration.

  An acoustic hole 24 is provided on the lower left side of the smoke detector 22 provided in the cover 18, and a speaker is built in behind this so that an alarm sound and a voice message can be output. An alarm stop switch 26 is provided below the smoke detector 22. The alarm stop switch also functions as an inspection switch.

  An LED 28 is arranged inside the alarm stop switch 26 as shown by a dotted line. When the LED 28 is lit, the LED 22 is lit through the semi-transparent switch cover portion of the alarm stop switch 26. It is understood from the outside.

  Further, a mounting hook 25 is provided at the upper part on the back side of the main body 20, and a screw or the like is screwed into the wall of the room to be installed, and the mounting hook 25 is attached to this screw, so that the residential alarm 10 can be installed on the wall surface. it can.

  In addition, although the residential alarm 10 of FIG. 2 has taken the example of the residential alarm which detects the smoke by the fire provided with the smoke detection part 22, it was equipped with the thermistor etc. which detect the heat by a fire in addition to this. House alarms, house alarms that detect gas leaks other than fire, and the like are also included in the scope of the present invention.

  Referring to FIG. 1 again, in the house 11 where the alarm system according to the present invention is installed, if a fire occurs in a child's room, for example, the slave resident alarm 10-4 detects the fire and starts an alarm. To do. Detecting this fire and initiating an alarm is referred to as “reporting” at the home alarm.

  When the slave home alarm device 10-4 is triggered, the slave home alarm device 10-4 functions as an interlock source, and the master home alarm device 10-1 and the slave home alarm devices 10-2, 10-3, which are the interlock destinations. An event signal indicating a fire alarm is transmitted wirelessly to 10-5.

  In the master home alarm device 10-1, the slave home alarm devices 10-2, 10-3, and 10-5, when an event signal indicating a fire alarm is received from the slave home alarm device 10-4 as the interlocking source. When the transmission source code obtained from the event signal matches the registered transmission source code registered in the memory by notification registration, it is recognized as an event signal from the resident alarm device belonging to the interlocking group, and based on the event content Performs an alarm action as a link destination.

  Here, as the alarm sound of the slave home alarm device 10-4, which is the link source, for example, “Woooo, fire alarm has been activated. On the other hand, the linked home alarm outputs a continuous voice message such as “Woo, another fire alarm has been activated. Please check”.

  When the alarm stop switch 26 shown in FIG. 2 is operated in a state in which the master home alarm device 10-1 and the slave home alarm devices 10-2 to 10-5 are outputting the alarm sound, the alarm sound stop processing is performed. . In this case, when an alarm stop operation is performed with one of the residential alarms, an event signal indicating the recovery accompanying the stop of the alarm instruction is transmitted to the other residential alarms. Alarms can also be stopped in conjunction.

Moreover, the master home alarm device 10-1 and the slave home alarm devices 10-2 to 10-5 have a function of monitoring the state of the home alarm device including a failure. This monitoring function includes, for example: (1) Low battery detection due to a decrease in battery voltage (2) Life warning when the remaining period becomes shorter than the predetermined life years (3) Automatic test of sensor unit to detect fire There is a failure alarm when an abnormality is detected.

  Unlike the fire alarm, the alarms (1) to (3) are not emergency alarms because they do not need to be alarmed immediately upon detection of an abnormality. About such an urgent alarm, in master residence police 10-1 and slave residence police 10-2-10-5 of this embodiment, based on time information, the time when an alert is needed It is determined whether the time zone is a daytime or a nighttime when sleeping, and if it is a nighttime time, the alarm output is suspended, and the next daytime daytime time, an urgent alarm output The time information is used to manage this time zone.

  In addition, the home alarm device that detected the failure causing the emergency alert wirelessly transmits an event signal indicating the occurrence of the failure to the other home alarm devices, and the other home alarm devices also output the event signal. The same failure alarm is output on condition that the original code matches the registered transmission source code registered in the memory by the notification registration.

  In this case as well, based on the time information received by the home alarm, if an event signal is received during the night time period, the alarm output is suspended and the alarm output is performed during the daytime period. Become.

  In addition, although it is made not to perform the warning sound output which uses a sound and a buzzer at night, you may make the warning by an LED indicator light. In addition, a sound alarm may be given as long as it is not disturbing at night, such as when a “beep” sound is output only once or intermittently at a relatively low volume. To the obi.

  FIG. 3 is a block diagram showing an embodiment of the device configuration of the master home alarm and the slave home alarm of FIG. In FIG. 3, the master home guard 10-1 includes a processor 30. For the processor 30, a radio circuit unit 32 including an antenna 31, a memory 34, a sensor unit 36, a notification unit 38, an operation unit 40, and a battery. A power source 42 is provided. The configuration of such a master home alarm device 10-1 is the same as that of the slave home alarm device 10-2.

  A transmission circuit 44 and a reception circuit 46 are provided in the wireless circuit unit 32 in the master home alarm device 10-1, so that event signals can be wirelessly transmitted and received between other home alarm devices. For example, in the case of Japan, the radio circuit unit 32 has a configuration conforming to the standard of a specific low-power radio station in the 400 MHz band. Of course, the radio circuit unit 32 has contents conforming to the standard of the assigned radio station in the area in places other than Japan.

  The reception circuit 46 performs an intermittent reception operation. The intermittent reception operation of the reception circuit 46 is, for example, intermittent reception of a period T12 (= T1 + T2) in which a pause time of T2 = 10 seconds is set, for example, following a reception operation time of T1 = 5 milliseconds. Corresponding to this intermittent reception, the transmission circuit 44 continuously transmits the event signal for a time T3 that is equal to or longer than the intermittent reception cycle T12 (= T1 + T2).

  The memory 34 is provided with a transmission source code 48 serving as an ID (identifier) for specifying a home alarm, and a group code 50 for specifying a group as necessary. As the transmission source code 48, the number of home guards provided in the country is predicted, and for example, a 26-bit code code is used so as not to overlap as the same code.

  Further, the transmission source management table 52 is stored in the memory 34. In the transmission source management table 52, the slave dwelling devices 10-2 to 10-5 shown in FIG. 1 and the interphone master unit 14 that perform time synchronization are configured in a linked group by a registration operation such as a notification registration process. The transmission source code of the provided wireless transmission unit 14a is registered.

  FIG. 5 shows the registration contents of the transmission source management table 52 of FIG. 3, corresponding to the indices 1-5, the transmission codes 0x00000001-0x00000004 of the slave mortgages 10-2 to 10-5 and the wireless transmission unit 14a. Is registered. The leading 0x indicates hexadecimal display.

  Referring again to FIG. 3, the sensor unit 36 of the master home alarm device 10-1 is provided with the smoke detector 22 in this embodiment, and outputs a smoke detection signal corresponding to the smoke density to the processor 30. is doing. In addition to the smoke detector 22, the sensor unit 36 may be provided with a thermistor or the like that detects a temperature due to a fire, or a detection element that detects other fire phenomena. In the case of a gas leak detection residence guard, a gas leak sensor is provided in the sensor unit 36.

  The notification unit 38 is provided with a speaker 54 and an LED 28. The speaker 54 outputs a voice message and an alarm sound from a voice synthesis circuit (not shown). The LED 28 displays abnormalities and failures such as fires such as blinking, blinking, and lighting.

  The operation unit 40 is provided with an alarm stop switch 26 and a mode switch 56. When the alarm stop switch 26 is operated, the alarm sound flowing from the master home alarm device 10-1 can be stopped. The alarm stop switch 26 also serves as an inspection switch in the present embodiment.

  That is, the alarm stop switch 26 is effective when an alarm sound is output from the notification unit 38 through the speaker 54. On the other hand, the alarm stop switch 26 functions as an inspection switch in a normal monitoring state in which no alarm sound is output. When the inspection switch is pressed, a notification voice message or the like is output from the notification unit 38.

  The mode switch 56 performs an operation for setting one of the operation mode of the master and the slave with respect to the home alarm. In the master home alarm device 10-1, the master mode is set by operating the mode switch 56, while in the slave home alarm device 10-2, the slave mode is also set by the mode switch 56 of the operation unit 40. ing.

  The battery power source 42 uses, for example, a predetermined number of alkaline dry batteries, and as a battery capacity, a battery life of about 10 years is guaranteed by reducing the power consumption of the entire circuit unit including the radio circuit unit 32 in the residential alarm. .

  The processor 30 includes hardware such as a CPU, a ROM, a RAM, an AD conversion port, and various input / output ports. As functions realized by execution of a program by the CPU, an abnormality monitoring unit 58, a mode setting unit 60, A time generation unit 62, a time distribution unit 64, and a master time management unit 66 are provided.

  When the smoke detection signal from the smoke detector 22 provided in the sensor unit 36 exceeds the fire level and detects a fire, the abnormality monitoring unit 58 generates an alarm sound indicating the interlock source from the speaker 54 of the notification unit 38, for example, “Woooo The fire alarm has been activated. Please confirm "and repeatedly output the event signal indicating the fire alarm from the antenna 31 to the other residential alarm by the transmission circuit 44 of the radio circuit unit 32. .

  Further, when the abnormality monitoring unit 58 receives an event signal indicating a fire alarm from any of the other home alarm devices by the reception circuit 46 of the wireless circuit unit 32, the abnormality monitoring unit 58 decodes the event signal to obtain a transmission source code, When the acquired transmission source code matches one of the registered transmission source codes registered in the transmission source management table 52, that is, when it is recognized that it is an event signal from the same group of residential alarms, the event content On the basis of the above, an alarm sound indicating the link destination, for example, “Woooo, another fire alarm has been activated. Please confirm” is continuously output from the speaker 54 of the notification unit 38.

  On the other hand, if the transmission source code obtained by decoding the event signal is not registered in the transmission source management table 52, it is determined that it is not an event signal from the same group of mortgages, and the event signal is discarded. Instead of simply discarding, a message such as “A signal outside the group was received” may be output.

  When the abnormality monitoring unit 58 detects a fire alarm and outputs an interlocking destination alarm sound, the LED 28 of the notification unit 38 is blinked, for example. On the other hand, when an interlocking destination alarm sound is output, the LED 22 is flashed. Thus, the display of the LED 22 can be distinguished by the interlocking source alarm and the interlocking destination alarm.

  The mode setting unit 60 determines the setting of either the master mode or the slave mode by the mode switch 56 provided in the operation unit 40, and sets the corresponding mode. In this case, in the master home alarm device 10-1, since the master mode is set by the mode switch 56, the mode setting unit 60 sets the operation mode of the master. When the mode setting unit 60 sets the master operation mode, the functions of the time generation unit 62, the time distribution unit 64, and the master time management unit 66 become effective.

  On the other hand, in the mode switch 56 provided in the operation unit 40 of the slave home alarm device 10-2, the slave mode is set. Similarly, the mode setting unit 60 provided in the processor 30 is set in the slave mode by the mode switch 56. When the slave operation mode is set and the slave operation mode is set, the functions of the time information reception unit 68 and the slave time management unit 70 become effective.

  In this case, that is, the residence alarm devices 10-1 and 10-2 each include a time generation unit 62, a time distribution unit 64, a master time management unit 66, a time information reception unit 68, and a slave time management unit 70 in the processor 30. Depending on the setting state of the mode setting unit 60, the function to be enabled is selected from among the functions. In FIG. 3, the home guard 10-1 is the master home guard, and the home guard 10-2 is the slave. Only the functions that are effective as a house alarm are shown.

  The mode switch 56 may not be provided, and may be manufactured in advance as a master house alarm and a slave house alarm. At this time, the mode setting unit 60 may also be eliminated, and only the necessary functions of the processor 30 may be installed.

  The time generation unit 62 that is enabled in the master operation mode in the processor 30 of the master home guard 10-1 generates time information that repeats in units of one day. The time information that is repeated in units of one day is time information that includes, for example, “hour / minute”. Generation of such time information can be realized by a simple clock counter that counts the divided clocks and outputs the hours and minutes. That is, a minute counter that outputs a one-minute clock and outputs it at 60 counts, and a time counter that counts an overflow output every 60 counts of the minute counter and resets it at 24 counts may be provided.

  The clock counter may be realized as a software timer executed by a program, or may be realized by hardware.

  The clock function by the time generation unit 62, that is, the clock function including the minute counter and the hour counter, performs time synchronization based on time information from the outside, so that even if an error occurs in the time information generated by the time generation unit 62, Can always maintain the correct value. The time synchronization for the time generation unit 62 is performed, for example, by transmitting a time synchronization signal at 12:00 noon from the wireless transmission unit 14a of the interphone master unit 14 of FIG. By receiving and rewriting the time counter and minute counter of the time generator 62 to “12” “00”, time synchronization can be achieved.

  Of course, the time information generated by the time generation unit 62 is not limited to “hour / minute”, but may be “hour / minute / second” or “year / month / day / minute / second”.

  The time distribution unit 64 transmits the time information generated by the time generation unit 62 from the radio circuit unit 32 to the slave mortgage alarm device 10-2 side by radio signal at predetermined intervals. The transmission cycle by the time generation unit 62 transmits time information at intervals of 1 minute, for example. As a result, on the slave home alarm device 10-2 side, time information in units of one minute from the master home alarm device 10-1 can be received and the current time can be recognized.

  Further, the master time management unit 66 executes processing according to a predetermined time zone based on the time information generated by the time generation unit 62. Specifically, for low battery alarms, life warnings, and fault alarms associated with automatic tests, which are emergency warnings, alarms were retained when alarms were detected during the nighttime period, and were retained during the daytime period. An alarm is output as an alarm.

  Next, slave house alarm 10-2 will be described. The configuration of the slave home alarm device 10-2 is basically the same as that of the master home alarm device 10-1, and the operation mode of the slave is set by the mode switch 56 provided in the operation unit 40. The time information receiving unit 68 and the slave time management unit 70 are effective as functions realized by execution of the CPU program.

  The time information receiving unit 68 of the slave home alarm device 10-2 receives the time information distributed from the master home alarm device 10-1, and recognizes the current time. Specifically, the time information reception unit 68 includes a time information register. When an event signal including time information is received by the reception circuit 46 of the wireless circuit unit 32, the time information is extracted from the received event signal and the time information is received. Store in register.

  The slave time management unit 20 executes processing according to a predetermined time zone based on the time information obtained by the time information reception unit 68. As processing according to this time zone, as with the master time management unit 66 of the master home alarm device 10-1, for the low battery alarm, the life warning and the fault alarm accompanying the automatic test, the alarm output is output for the night time zone. Reserved and outputs alarms during the daytime.

  FIG. 5 is an explanatory diagram showing the format of the event signal used in this embodiment. In FIG. 5, the event signal 72 includes a transmission source code 48, a group code 50, an event code 74, and time information 76. The transmission source code 48 is a 26-bit code, for example. The group code 50 is, for example, an 8-bit code, and the same group code is set for a plurality of residential alarms constituting the same group.

  The event code 74 is a code indicating the event content such as an abnormality or failure such as a fire or gas leak. In this embodiment, a 3-bit code is used. For example, “001” is a fire, “010” is a gas leak, “011” is a failure, “100” is time distribution, “101” is time synchronization, The rest is reserved.

  Note that the number of bits of the event code 74 can be further increased to 4 bits and 5 bits when the type of event increases, thereby representing a plurality of types of event contents.

  FIG. 6 is a flowchart showing the processing operation of the residential alarm in the present embodiment, and both the master and slave residential alarms have the same operation.

  In FIG. 6, when power is supplied to each circuit unit including the processor 30 by removing the electrode seal of the battery power source 42 provided in the home alarm device at the time of shipment, the processor 30 performs initialization processing in step S <b> 1. After that, in step S2, the presence or absence of a fire alarm is determined.

  Whether or not there is a fire alarm is determined by whether or not the smoke detection signal from the smoke detector 22 provided in the sensor unit 36 exceeds a predetermined fire level. If a fire alarm is determined in step S2, the process proceeds to step S3, and an event signal of the fire alarm is transmitted to another house alarm, and then the fire alarm of the interlocking source is sent to the speaker of the notification unit 38 in step S4. The sound output from 54 and the lighting control of the LED 28 are output.

  After performing the fire alarm of the interlocking source, it is determined whether or not there is an alarm stop operation by the fire alarm stop switch 26 in step S9. When the alarm stop operation is determined in step S9, the alarm is stopped in step S10. After that, in step S11, a recovery event signal is transmitted to another residential alarm device to stop the alarm at the interlocking destination.

  On the other hand, if a fire alarm is not determined in step S2, it is checked in step S5 whether a fire alarm event signal has been received from another house alarm. When it is determined in step S5 that a fire alarm event signal has been received from another home alarm device, the event signal received in step S6 is analyzed to obtain a transmission source code, and the transmission source management table 52 is registered in step S7. Compared with the transmitted source code, if they match, it is determined to be an event signal from another resident alarm device included in the same group, and is validated. In step S8, a fire alarm at the interlock destination is output based on the event content. If there is an alarm stop operation in step S9, the alarm is stopped in step S10, and then a recovery event signal is transmitted in step S11.

  If the source code acquired from the event signal received in step S7 is not registered in the source management table 52, the received event signal is discarded and nothing is performed.

  After transmitting the recovery event signal in step S11, if it is determined in step S12 that a recovery event signal has been received from another residential alarm device, the process proceeds to step S13 to perform a recovery process. In this recovery process, when the fire alarm of the interlocking source or the interlocking destination is performed in step S4 or step S8, the alarm is stopped. On the other hand, if the fire alarm at the link source or link destination is not performed in step S4 or step S8, the recovery event signal is ignored.

  Subsequently, the process proceeds to step S14, where it is checked whether or not the setting is a master setting. If the setting is a master setting, the master time management process in step S15 is executed. If the setting is a slave setting, the slave time management in step S16 is performed. Execute the process.

  FIG. 7 is a flowchart showing details of the master time management process in step S15 in FIG. 6, and the time generator 62, the time distributor 64, and the master provided in the processor 30 of the master home alarm device 10-1 in FIG. Processing of the time management unit 66 is performed.

  In FIG. 7, the master time management process determines whether or not the time information transmission timing is 1 minute, for example, at step S <b> 21, and if the transmission timing is determined, proceeds to step S <b> 22. Send time information. Specifically, an event signal in which the time information generated by the time generation unit 62 is set in the time information 76 of the event signal 72 shown in FIG. 5 is transmitted to the slave home alarm device.

  Subsequently, in step S23, it is determined whether or not an emergency warning such as a low battery warning is generated including the previous hold, and if the emergency warning is generated, the process proceeds to step S24 and the time generation unit 62 generates the current Check if the time is during the daytime. If it is a daytime time zone, the process proceeds to step S25 to output an emergency warning such as a low battery warning. If it is a night time zone, the process proceeds to step S26, and a hold is made without outputting an emergency warning.

  Subsequently, in step S27, it is determined whether or not a time synchronization event signal has been received. If a time synchronization event signal has been received, the process proceeds to step S28, and the current time generated by the time generation unit 62 is obtained by reception of the event signal. Update at the specified synchronization time.

  FIG. 8 is a flowchart showing details of the slave time management processing in step S16 of FIG. 6, and the time information receiving unit 68 and slave time management provided in the processor 30 of the slave mortgage alarm device 10-2 shown in FIG. The processing of the unit 70 is performed.

  In FIG. 8, the slave time management process checks whether or not the time information is received from the master home alarm device 10-1 in step S31. When an event signal including the time information is received, the slave time management process starts from the event signal in step S32. The time information register is updated with the obtained time information.

  Subsequently, in step S33, it is determined whether or not an emergency warning including the previous hold is generated. If the emergency alarm is determined, the process proceeds to step S34, where the current time obtained from the time information register is the daytime time. Check if it is a belt. If it is a daytime time zone, the process proceeds to step S35, and an urgent alarm such as a low battery alarm is output. On the other hand, if it is a night time zone, an urgent alarm such as a low battery alarm is put on hold in step S36.

  Furthermore, in the anomaly monitoring unit 58 of the present embodiment, when receiving a fire alarm or recovery event signal from another resident alarm, it is correct by referring to the time information included in each event signal. Processing according to the order of event occurrence can be performed.

  This is because it is assumed that the event occurrence time and the event signal reception time are interchanged by the path of the radio signal from the resident alarm. For example, in FIG. 1, the event signal from the slave mortgage 10-5 in the garage 15 is received by the master resident alarm 10-1 via the repeater 12, while the slave resident alarm 10-3 in the master bedroom. The event signal from the slave home alarm device 10-1 is directly received by the master home alarm device 10-1, and the event signal from the slave home alarm device 10-5 may be delayed in time by the amount relayed by the relay device 12.

  In such a case, for example, the slave home alarm device 10-5 in the garage 15 transmits a fire alarm event signal as a false alarm due to a malfunction of the sensor unit 35, and notices this error information, for example, the slave home alarm device 10- in the master bedroom. Suppose that an alarm stop operation is performed in 3 and a recovery event signal is transmitted.

  In this case, the fire alarm event of the false alarm is earlier in time and subsequently becomes a recovery event. However, due to the delay in the transmission time via the repeater 12, the slave master alarm device is connected to the first master home alarm device 10-1. The recovery event signal from 10-3 is received, and then the fire alert event signal from the slave mortgage 10-5 in the garage 15 is received.

  In such a reception state, if the process is performed as it is by the master home alarm device 10-1, the first recovery is performed. However, since the fire alarm is not issued, the recovery event signal is discarded. Subsequently, when the event signal of the fire alarm is determined, the master home alarm device 10-1 issues a fire alarm of the interlocking destination.

  In such a situation, it becomes meaningless that the alarm stop operation was performed by the alarm stop operation of the slave home alarm device 10-3 in the main bedroom in response to the false alarm of the slave home alarm device 10-5 in the garage 15.

  Therefore, in the present embodiment, the time information included in the recovery event signal received first is compared with the time information included in the next fire alarm event signal received, so that the event contents are followed in order of time. Execute the process. As a result, it can be seen that although the reception time is different, the time information is that the event signal of the fire alarm is first, and then the event signal of the recovery is sent. It is possible to perform a correct operation in accordance with the actual event generation order, in which an interlocking destination alarm is issued from the alarm event signal and then the alarm is stopped according to the recovery event signal.

  In addition, although the above embodiment was taken as an example of a residential alarm for fire detection, an alarm for detecting other appropriate abnormalities such as a gas leak alarm or a security alarm The distribution of the time information on the master side of this embodiment and the time management on the slave side based on this can be applied to the device.

  Moreover, although said embodiment took the case where the sensor part was integrally provided in the alarm device as an example, as another embodiment, the alarm device which provided the sensor part separately from the alarm device may be sufficient. .

  In the above embodiment, the case where a group code is added to the event signal is taken as an example. However, since the determination of the interlocking group is performed in the transmission source management table 52, the group code is excluded. Also good.

  In addition, the configuration of each unit and the flowchart processing shown in the above embodiment are merely examples, and the present invention is not limited to this example.

The present invention is not limited to the above-described embodiments, includes appropriate modifications that do not impair the objects and advantages thereof, and is not limited by the numerical values shown in the above-described embodiments.
