  In FIG. 1, the residential alarm 10 according to the present embodiment includes a cover 12 and a main body 14. A smoke inlet is opened in the center of the cover 12, and a smoke detector 16 is disposed inside the cover 12 so that a fire is detected when smoke from the fire reaches a predetermined concentration.

  An acoustic hole 18 is provided on the lower left side of the smoke detector 16 provided in the cover 12, and a buzzer and a speaker are built in behind this so that an alarm sound and a voice message can be output. An alarm stop switch 20 is provided below the smoke detector 16. The alarm stop switch 20 also has a function as an inspection switch for instructing a functional inspection of the home alarm. For example, when the alarm stop switch 20 is operated during a fire alarm, the alarm is stopped, and when the alarm stop switch 20 is operated in a normal state, a function check is started and the result is notified.

  The alarm stop switch 20 includes a switch cover formed of a translucent member and a tact switch (not shown) arranged inside the switch cover. In the vicinity of the tact switch in the switch cover, an LED 22 is arranged as shown by a dotted line. When the LED 22 is lit, the LED 22 is lit through the switch cover portion of the alarm stop switch 20 so that the lighting state of the LED 22 can be seen from the outside. ing.

  Further, a mounting hook 15 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 installation room, and the housing hook 10 can be installed on the wall surface by attaching the screw to the mounting hook 15 with a screw. it can.

  In addition, in the residential alarm 10 of FIG. 1, although the residential alarm which detects the smoke by the fire provided with the smoke detection part 16 is taken as an example, temperature of the thermistor etc. which detects the heat by a fire besides this is also taken. House alarms with detection elements, house alarms that detect other physical phenomena associated with fires, alarms that detect gas leaks in addition to fires, various alarms that detect intruders, earthquakes, and other abnormalities, etc. Alarm devices formed by combining these are also included in the subject of the present invention.

  Moreover, the alarm system of this invention may mix the above different alarm devices.

  FIG. 2 is an explanatory diagram showing the installation state of the house alarm of the present embodiment with respect to the house. In the example of FIG. 2, the residence guards 10-1 to 10-4 of the present embodiment are installed in the kitchen, living room, main bedroom, and child room provided in the house 24, and are further built outdoors. Also installed in the garage 26 is a residence guard 10-5.

  Each of the residential police devices 10-1 to 10-5 has a function of transmitting and receiving event signals wirelessly and a function of relaying received event signals, and further includes five residential police devices 10-1 to 10-10. -5 constitutes a group and monitors the entire house for fire.

  If a fire has occurred in the child's room of the house 24, the residence guard 10-4 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 resident alarm 10-4 is triggered, the resident guard 10-4 functions as an interlocking source, and fires are issued to the other resident alarms 10-1 to 10-3 and 10-5 that are the interlocking destinations. An event signal indicating is transmitted by radio. Among the other home alarm devices 10-1 to 10-3, 10-5, the home alarm device that has received the event signal indicating the fire alarm from the home alarm device 10-4 that is the interlocking source is the alarm as the interlocking destination. The operation is performed and the received event signal is relayed to other home alarm devices.

  Here, as the alarm sound of the home alarm device 10-4 that is the link source, for example, “Please confirm that the Woo Woo fire alarm has been activated” is output continuously by voice message, and the LED 22 is lit and driven. . On the other hand, for the linked home alarm devices 10-1 to 10-3 and 10-5, while continuously outputting a voice message such as “Please confirm that another fire alarm has been activated” The LED 22 is driven to blink at a predetermined first period.

  When the alarm stop switch 20 provided in the residence guard shown in FIG. 1 is operated in a state in which the residence guards 10-1 to 10-5 are emitting an alarm sound, a warning sound stop process is performed. Here, one of the following stop processes is performed as the alarm sound stop process of the present embodiment.

  (1) When the alarm stop switch of the alarm device 10-4 during alarm is operated as the interlock source, the alarm sounds of all the alarm devices 10-1 to 10-5 including the interlock destination are stopped.

  At this time, the LED 22 is extinguished in the interlocking destination home alarm devices 10-1 to 10-3, 10-5, but only the interlocking source LED 22 continues to be lit, flashing, and blinking at least for a predetermined period. May be. As a result, the alarm history of the link source remains, and it becomes easy to specify the source of the alarm after the fire is extinguished and to identify the home alarm device that issued the false or non-fire alarm.

  (2) When the alarm stop switch of any of the resident alarms 10-1 to 10-3, 10-5 being alarmed is pressed as the interlocking destination, only the interlocking resident alarm 10-4 is The alarm sound is continuously output, and the interlocked residence alarm devices 10-1 to 10-3 and 10-5 stop outputting the alarm sound.

  At this time, in the interlocking home resident alarm 10-4, the LED 22 may be continuously turned on or may be driven to blink in a second cycle different from the first cycle of the interlocking destination. Then, in the interlocking destination home alarm devices 10-1 to 10-5, the LED 22 may be turned off, but the blinking may be continued in the first cycle, or the same as the interlocking source. It may be made to blink at a cycle of 2. In this way, even in the interlocking destination alarm device installed in a place where the alarm sound of the interlocking home resident alarm 10-4 cannot be heard, it is possible to know that the interlocking source is still in alarm. It is possible to clearly identify and identify other alarm devices that have received an alarm stop signal from the interlocked alarm device that has performed the alarm stop operation.

  (3) If you operate the alarm stop switch of any of the residential alarms 10-1 to 10-5 that are in alarm, the alarm sound of all the residential alarms will be heard regardless of the interlocking destination and the interlocking source. Stop.

  At this time, the LED 22 of each residential alarm can be controlled similarly to (1).

  (4) The stop process of (1) is the first mode, the stop process of (2) is the second mode, the stop process of (3) is the third mode, and at least one of the two modes is selected. Select and stop processing.

  FIG. 3 is a block diagram showing an embodiment of a residential alarm according to the present invention. FIG. 3 shows in detail the circuit configuration of the five home guards 10-1 to 10-5 shown in FIG. The other residential alarm devices 10-2 to 10-5 have the same configuration as the residential alarm device 10-1.

  The home alarm device 10-1 includes a CPU 28. The CPU 28 is provided with a radio circuit unit 30, a recording circuit unit 32, a sensor unit 34, a notification unit 36, and an operation unit 38 including an antenna 31, and power is supplied to each necessary unit. A battery power supply 40 is provided.

  The wireless circuit unit 30 is provided with a transmission circuit 42 and a reception circuit 44 so that event signals can be transmitted and received wirelessly and relayed between the other residential alarm devices 10-2 to 10-5. Yes. As the radio circuit unit 30, in Japan, for example, STD-30 (radio equipment standard of a low power security system radio station) or STD-T67 known as a standard of a specific low power radio 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, the radio circuit unit 30 has contents conforming to the standard of the assigned radio station in the area in places other than Japan.

  The recording circuit unit 32 is provided with a memory 46. The memory 46 stores a transmission source code 52 that is an ID (identifier) for identifying a house alarm, and a group code 54 for configuring a group that performs a linked alarm with a plurality of house alarms as shown in FIG. Yes. As the transmission source code 52, 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 be duplicated as the same code.

  The group code 54 is a code that is set in common to a plurality of house alarm devices constituting the group, and the group code included in the event signal from another house alarm device received by the wireless circuit unit 30 is registered in the memory 46. When this event signal matches the group code 54, the event signal is received and processed as a valid signal. Can be avoided.

  The memory 46 is provided with a group management table 70 and a relay management table 72. In the group management table 70, the transmission source codes of the residential alarm devices 10-1 to 10-5 constituting the group are registered in advance. The relay management table 72 stores information regarding event signals that have been relayed once.

  In the present embodiment, the sensor unit 34 is provided with the smoke detector unit 16. The smoke detector 16 outputs a detection signal when it detects smoke. The detection signal from the smoke detector 16 is taken into the CPU 28 (AD conversion), and when the CPU 28 exceeds a predetermined fire level, a fire alarm is determined, and the detection signal from the smoke detector 16 is lowered to reduce the fire level. It is determined that the fire report has been lost (fire recovery) by falling below.

  In addition to the smoke detector 16, the sensor unit 34 may be provided with a thermistor that detects a temperature rise due to a fire. In the case of an alarm device for monitoring gas leakage, a gas leakage sensor is provided in the sensor unit 34.

  The notification unit 36 is provided with a speaker 58 and an LED 22. The speaker 58 outputs a voice message or an alarm sound from a voice synthesis circuit unit (not shown). The LED 22 displays an abnormality such as a fire by blinking, blinking, or lighting through a drive circuit (not shown).

  The operation unit 38 is provided with an alarm stop switch 20. When the alarm stop switch 20 is operated during the alarm, the alarm sound output from the home alarm device 10-1 can be stopped. The alarm stop switch 20 is also used as an inspection switch in this embodiment. The alarm stop switch 20 is accepted as an alarm stop operation only when operated during an alarm. On the other hand, the alarm stop switch 20 functions as an inspection switch in the normal monitoring state where no alarm sound is output, and when the inspection switch is operated at a time other than during an alarm, a voice message for inspection is output from the notification unit 36. Is done.

  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 about 10 due to a reduction in power consumption of the entire circuit unit including the wireless circuit unit 30 in the residential alarm 10-1. The battery life of the year is guaranteed.

  The CPU 28 is provided with an event processing unit 60 and a relay processing unit 62 as functions realized by executing the program.

  The event processing unit 60 generates an abnormality (fire) based on the detection signal of the sensor unit 34, stops the alarm by the operation unit 38, detects a failure of the battery power source 40 or the sensor unit 34, and eliminates an abnormality based on the detection signal of the sensor unit 34. When a state change such as recovery and failure recovery that eliminates the failure of the battery power source 40 or the sensor unit 34 is detected as an event, an event signal indicating the detected event is sent to the interlocking destination alarm after performing an event handling process as a linkage source On the other hand, when the event signal is received from the interlocking source alarm device, if it is not the interlocking source, the event corresponding process as the interlocking destination is performed.

  In order to realize this function, the event processing unit 60 includes an abnormality (fire) monitoring unit 64, an event detection unit 61 including a failure detection unit 65, an alarm stop unit 66, and a recovery unit 68.

  When the abnormality monitoring unit 64 determines a fire based on the detection signal from the smoke detecting unit 16 provided in the sensor unit 34, an alarm sound indicating the interlocking source, for example, “Woo Woo Fire Alarm “Please confirm that it has been activated” and repeatedly driving the LED 22, and sending an event signal indicating a fire alarm via the communication control unit (not shown) of the event processing unit 60 by the transmission circuit 42 of the wireless circuit unit 30. Transmission is performed from the antenna 31 toward the other residential alarm devices 10-2 to 10-5.

  Moreover, when the abnormality monitoring unit 64 receives an event signal indicating a fire alarm from any of the other residential alarm devices 10-2 to 10-5 by the receiving circuit 44 of the wireless circuit unit 30, the abnormality monitoring unit 64 is not an interlocking source. In this case, an alarm sound indicating the link destination, for example, “Please confirm that another fire alarm has been activated” is continuously output from the speaker 58 of the notification unit 36.

  Here, when the abnormality monitoring unit 64 detects a fire alarm and outputs an interlocking source alarm sound, for example, the LED 22 of the notification unit 36 is blinked, while when the interlocking destination alarm sound is output, the LED 22 of the notification unit 36 is emitted. Blinks. Alternatively, the emission cycle of the LED is made different for the case where the interlocking source alarm sound is output and the case where the interlocking destination alarm sound is output. Thereby, the display of the LED 22 in the interlocking source alarm and the interlocking destination alarm can be distinguished. Furthermore, the power consumption of either alarm device can be suppressed by making the brightness of the LED emission different between the two. For example, since a fire has occurred in the monitoring area of the interlock source, an alarm (display alarm) for the purpose of visual confirmation is considered to be relatively low in importance. It is possible to make the display length longer, to darken the display, or not to perform a display alarm.

  Of course, the blinking or flashing display of the same LED 22 may be used for both the interlocking source alarm and the interlocking destination alarm.

  When the alarm stop unit 66 detects the operation of the alarm stop switch 20 provided in the operation unit 38 during the alarm output indicating the interlock source, the alarm stop unit 66 stops the alarm sound indicating the interlock source output from the speaker 58, and An alarm stop event signal is transmitted from the transmission circuit 42 of the wireless circuit unit 30 to the other residential alarm devices 10-2 to 10-5 via a communication control unit (not shown), and the other residential alarm devices 10-2 to 10-10 are transmitted. Stop the alarm sound at the link destination in -5.

  In this case, without stopping the alarm sound indicating the interlocking source output from the speaker 58, the alarm stop event signal is sent from the transmission circuit 42 of the wireless circuit unit 30 to the other residential alarm devices 10-2 to 10-5. It is also possible to transmit and stop the alarm sound of the interlocking destination in the other residential alarm devices 10-2 to 10-5 and leave only the interlocking source alarm. Of course, it is also possible to operate according to the stop processing of the first to third modes shown in the above (1) to (3) and the first to third modes selected in (4).

  When the alarm stop unit 66 detects the operation of the alarm stop switch 20 of its own operation unit 38 during the alarm indicating the interlock destination, the alarm stop unit 66 stops the alarm sound indicating the interlock destination output from the speaker 58 and causes the LED 22 to stop. Predetermined display control is performed, and an alarm stop event signal is transmitted from the transmission circuit 42 of the wireless circuit unit 30 to the other residential alarm devices 10-2 to 10-5.

  Furthermore, when the alarm stop unit 66 receives an alarm stop event signal from the other residential alarm devices 10-2 to 10-5 by the receiving circuit 44 of the wireless circuit unit 30 during the alarm output indicating the link destination, Is stopped and predetermined display control is performed.

  The recovery unit 68 stops the interlocking source alarm and returns it to the normal state when the smoke disappears from the smoke detection unit 16 provided in the sensor unit 34 and the event signal indicating the fire recovery is illustrated. If the transmission circuit 42 of the wireless circuit unit 30 transmits to the interlocking dwelling devices 10-2 to 10-5 via the communication control unit that does not operate, When an event signal indicating fire recovery is received from any of the alarm devices 10-2 to 10-5 by the receiving circuit 44 of the wireless circuit unit 30, the interlocking destination alarm is stopped and returned to the normal state.

  As a result, when the interlocking source alarm is issued by the resident alarm 10-1 and the fire condition is resolved thereafter, and the detection signal from the sensor unit 34 falls below the fire level, the recovery processing unit 64 automatically causes the interlocking source. Can be stopped and restored to the normal monitoring state. At this time, the LED 22 may be driven as a history display.

  At the same time, an event signal indicating a fire recovery is sent from the home police device 10-1 to the other home police devices 10-2 to 10-5 that have issued the linkage destination alarm, and each linkage source alarm is automatically stopped. Therefore, it is not necessary to go to the house alarm devices 10-2 to 10-5 to perform the alarm stop operation.

  The relay control unit 62 relays the event signal when receiving the event signal from the interlocking source or the relay source alarm device. In addition, the event processing unit 60 transmits an event signal including a serial number (hereinafter referred to as “serial number”) and a transmission source code that sequentially increase with each transmission, and the relay control unit 62 receives the link. When the event signal is received from the original or relay source alarm device, the serial number and the transmission source code pair included in the event signal are stored in the relay management table 72 of the memory 46 and the already received serial number and transmission If they match, the same event signal has already been relayed, so that the relay of the event signal is terminated and the same event signal is not repeatedly relayed. This process will be described in detail later.

  The circuit unit provided in such a home alarm device 10-1 is the same for the other home alarm devices 10-2 to 10-5, and the transmission source code 52 stored in the memory 46 is a serial number or the like. It is a code unique to each home alarm.

  FIG. 4 is an explanatory diagram showing the format of the event signal used in this embodiment. In FIG. 4, the event signal 48 includes a serial number 50, a transmission source code 52, a group code 54, and an event code 56.

The serial number 50 is a serial number indicating the order of event signals, and is incremented by one each time an event signal is transmitted. Moreover, the serial number 50 is produced | generated asynchronously in each of the residence alarm devices 10-1 to 10-5. This serial number may be initialized, for example, at each inspection unit at the time of inspection processing or recovery processing, or at the same time for all residential alarm units within the group at the time of inspection interlocking processing or recovery interlocking processing. You may make it do. In addition, the serial number and transmission source code pair stored in the relay management table may be duplicated if only the latest transmission source code is stored. Can avoid wasted relays. In addition, the memory capacity of the home alarm is small. (Please consider making a claim)
The transmission source code 52 is a 26-bit code, for example. Moreover, the group code | symbol 54 is an 8-bit code | symbol, for example, and the same group code | cord | chord is set, for example, about the five dwelling devices 10-1 to 10-5 of FIG. 3 which comprise the same group.

  As the group code 54, in addition to setting the same group code for the same group of house alarms, a reference code common to the house alarms constituting the predetermined group, and a sender unique to each house alarm A different group code may be used for each residential alarm obtained from the calculation with the code.

  The event code 56 is a code representing the event contents such as fire and gas leak. In this embodiment, a 3-bit code is used. For example, “001” indicates a fire, “010” indicates a gas leak, “ “011” indicates recovery, “100” indicates alarm stop, “101” indicates failure, “110” indicates failure recovery, and “111” indicates reserve. It should be noted that the number of bits of the event code 56 can be increased to 4 bits and 5 bits when the type of event is increased, thereby representing a plurality of types of event contents.

  FIG. 5A is an explanatory diagram showing the contents of the group management table 70 stored in the memory 46 of FIG. 3, and the transmission source codes of the residential alarm devices 10-1 to 10-5 belonging to the same group of FIG. The case of 101, 102, 103, 104, 105 is taken as an example.

  For example, when registering the group management table 70 at the time of factory shipment or installing in a house, the five alarm devices 10-1 to 10-5 are arranged in one place such as a work table to perform the notification registration work. Can be realized.

  As an example of the alarm registration work shown here, one of the mortgages 10-1 to 10-5 is sequentially sent as a registration transmission mode, and a registration event signal is transmitted. The registered event signal is received by the other residential alarm, and the transmission source code included in the registered event signal is acquired and registered in the group management table 70 of the memory 46.

  From the transmission source code registered here, a common code common to the in-group mortgages is generated by arithmetic processing. As a simple example, a value obtained by adding the lower digits of each transmission source code can be used. Of course, the common code determined in advance may be directly registered in the residential alarm belonging to the same group.

  FIG. 5B is an explanatory diagram showing the contents of the relay management table 72 stored in the memory 46 of FIG. 3. For example, an event signal is received from the mortgage 10-1 having the transmission source code = 101 and relayed. The stored contents are shown.

  For example, assuming that an event signal is received from the home guard 10-1 without being registered in the relay management table 72, a set of serial number = 00001 and source code = 101 is acquired from the received event signal. Since there is no same set in the relay management table 72, the event signal is relayed and registered, and a set of serial number = 00001 and source code = 101 is registered in the relay management table 72.

  After that, when the same event signal relayed is received again via relaying by another resident alarm, the combination of the serial number and the transmission source code acquired from the event signal is the pair registered in the relay management table 72. It is determined that they match, and relaying is terminated, and no further relaying is performed.

  Note that a terminal that transmits a signal must add a code that can specify a transmission source to the transmission signal in accordance with a legal standard related to wireless communication. For this reason, even in the resident alarm device of this embodiment, the transmission source code must be added at the time of signal transmission. Will be included. Accordingly, in the event signal transmitted (not relayed) by the resident alarm serving as the interlocking source, the transmission source code and the relay transmission source code are the same. Then, the resident alarm device that transmits the relay event signal transmits an event signal including its own relay transmission source code and the linkage source transmission source code. In the following description, the relay transmission source code is omitted.

  FIG. 6 is a flowchart schematically showing a basic processing example according to the present embodiment, which is activated when the power supply from the battery power source 40 is started. First, in step S1, initialization processing and self-diagnosis are performed. This processing includes setting of a group code for forming a group with, for example, five residence police devices 10-1 to 10-5 installed in the same dwelling unit. If there is no failure in the self-diagnosis, the fire monitoring process in step S2 and the fault monitoring process in step S3 are repeatedly executed. The inspection instruction interrupt processing is omitted.

  FIG. 7 is a flowchart showing details of the fire monitoring process including the relay control in step S2 of FIG. 6, and is a process by execution of the program of the CPU 28 of FIG.

  In FIG. 7, the fire monitoring process monitors the fire alarm in step S11, and determines the fire alarm when the detection signal output from the smoke detector 16 provided in the sensor unit 34 exceeds a predetermined fire level. Then, the process proceeds to step S12, and an event signal including a serial number, a transmission source code, and an event code indicating a fire alarm is wirelessly transmitted to the other residential alarm devices. In step S13, an alarm indicating the interlocking source is output.

  Subsequently, in step S14, it is determined whether or not there is a fire recovery in which the smoke detection unit 16 loses smoke, the detection signal of the sensor unit 34 decreases, and the fire alarm disappears. If the fire alarm continues, step S14 is performed. In S15, it is determined whether or not there is an alarm stop operation by the alarm stop switch 20, and if there is no alarm stop operation, the process of determining whether or not an alarm stop event signal is received from another residential alarm is repeated in Step S16. In addition, while the fire alarm is continuing, the transmission of the event signal indicating the fire alarm is repeated every predetermined time.

  During the processing cycle of steps S14 to S16, when the smoke is exhausted from the smoke detector 16, fire recovery is determined in step S14, and an event signal for fire recovery is transmitted to another house alarm in step S18. Go ahead and stop the interlocking source alarm, and in this case, return to the normal monitoring state.

  If it is determined in step S16 that an alarm stop event signal has been received from another house alarm device, relay control is performed in step S17, and then the process proceeds to step S20 to stop the interlocking source alarm. Here, the details of the relay control in step S17 are as shown in the flowchart of FIG.

  The relay control in FIG. 8 obtains a pair of serial number and source code from the event signal received in step S31, determines whether or not it matches the group registered in the relay management table 72 in step S32, and In this case, the process proceeds to step S33, and a set of serial numbers and transmission source codes is registered in the relay management table 72, and then the event signal is relayed and transmitted in step S34.

  If it matches the registered group in step S32, the process proceeds to step S35 and the relay is terminated. The pair registered in the relay control table 72 is updated by overwriting the pair of the serial number and the transmission source code acquired from the next received event signal. Further, a fixed number of sets may be stored in first-in last-out without being overwritten.

  When an event signal is transmitted as a linkage source, it is not re-relayed when the event relayed from the linkage destination is received. For example, when an event signal is sent as a linkage source, its own relay management table It is possible to store the own transmission source code and serial number.

  Referring to FIG. 7 again, if it is determined in step S15 that the own alarm stop operation has been performed, the process proceeds to step S19, and the event signal including the serial number, the transmission source code, and the event code indicating the alarm stop is sent to the other home alarm devices Is transmitted, the interlocking source alarm is stopped in step S20.

  If it is determined in step S15 that the own alarm stop operation has been performed, or if an alarm stop event signal is received from another resident alarm in step S16, the interlock source alarm stop in step S20 is skipped and the alarm stop is performed. Only the interlocking source alarm may be left and continued for the operation.

  On the other hand, if it is not a fire alarm in step S11, it is determined in step S21 whether or not an event signal indicating a fire alarm from another resident alarm is received. When it is determined that an event signal indicating a fire alarm has been received from another house alarm, the process proceeds to step S22, and after relay control shown in FIG. 8 is performed, an alarm indicating the interlock destination is output in step S23.

  Subsequently, in step S24, it is determined whether or not an event signal indicating a fire recovery from another residence police is received. When an event signal indicating a fire recovery is received, the process proceeds to step S28 and the relay control shown in FIG. 8 is performed. Then, the process proceeds to step S29 to stop the interlocking destination alarm, and in this case, the normal monitoring state is restored.

  Subsequently, in step S25, it is checked whether or not an event signal indicating an alarm stop from another residential alarm is received. If it is determined that an event signal indicating an alarm stop is received, the process proceeds to step S28 and is shown in FIG. After relay control is performed, an alarm indicating the interlock destination is stopped in step S29.

  If no event signal indicating an alarm stop is received in step S25, it is determined in step S26 whether or not an alarm stop operation is performed by the alarm stop switch 20, and if an alarm stop operation is determined, a serial number and a transmission source code are determined in step S27. ..: After transmitting an event signal including an event code indicating an alarm stop to another residential alarm device, an alarm indicating an interlock destination is stopped in step S29.

  FIG. 9 is a flowchart showing details of the failure monitoring process including the relay control in step S3 of FIG. 6, and the sensor failure of the sensor unit 34 will be described as an example as follows.

  In FIG. 9, the presence or absence of detection of a sensor failure in the sensor unit 34 is monitored in step S41, and the detection signal from the sensor unit 34 is at a predetermined zero level (normal signal level at normal time: the detection capability of the sensor is lost). In order to check whether there is no smoke, a slight signal is output even if there is no smoke generation), the sensor failure is detected and the process proceeds to step S42, where the sequence number, source code, and event indicating the sensor failure are detected. An event signal including a code is transmitted to other home alarm devices by radio. In step S43, a failure alarm indicating the link source is output.

  Subsequently, in step S44, it is determined whether or not the detection signal from the sensor unit 34 is restored to the zero point level. If the sensor failure continues, the presence or absence of an alarm stop operation by the alarm stop switch 20 is determined in step S45. If there is no alarm stop operation, the process of determining whether or not an alarm stop event signal has been received from another residential alarm is repeated in step S46. In addition, while the sensor failure is continuing, the transmission of the event signal indicating the sensor failure is repeated every predetermined time.

  When the detection signal recovers from the sensor unit 34 to the zero point level during the processing cycle of steps S44 to S46, failure recovery is determined in step S44, and an event including a serial number, a transmission source code, and an event code indicating failure recovery in step S48. After transmitting the signal to the other house alarm device, the process proceeds to step S50 to stop the interlocking source failure alarm, and in this case, the normal monitoring state is restored.

  If it is determined in step S46 that an alarm stop event signal has been received from another residential alarm, the process proceeds to step S47 to perform the relay control shown in FIG. 8, and then proceeds to step S50 to stop the interlocking source failure alarm. Further, if it is determined in step S45 that its own alarm stop operation has been performed, the process proceeds to step S49, and an event signal including an event code indicating a serial number, a transmission source code, and an alarm stop is transmitted to the other home alarm devices. In S50, the interlocking source trouble alarm is stopped.

  On the other hand, if no sensor failure is detected in step S41, it is determined in step S51 whether or not an event signal has been received indicating a failure from another home alarm. When it is determined that an event signal indicating a sensor failure is received from another house alarm device, the process proceeds to step S52 and relay control shown in FIG. 8 is performed, and then the process proceeds to step S53 to output a failure alarm indicating a link destination.

  Subsequently, in step S54, it is determined whether or not an event signal indicating failure recovery has been received from another residential police, and when an event signal indicating failure recovery is received, the process proceeds to step S58 to perform the relay control shown in FIG. After having performed, it progresses to step S59 and stops the failure alarm which shows an interlocking destination, and returns to a normal monitoring state in this case.

  If no event signal indicating a failure is received in step S54, it is checked in step S55 whether an event signal indicating an alarm stop from another resident alarm is received, and an event signal indicating an alarm stop is received. If it discriminate | determines, after progressing to step S58 and performing the relay control shown in FIG. 8, the alarm which shows an interlocking destination will be stopped by step S59.

  If no event signal indicating an alarm stop is received in step S55, the presence or absence of an alarm stop operation by the alarm stop switch 20 is determined in step S56. If the alarm stop operation is determined, a serial number and a transmission source are determined in step S57. After transmitting the event signal including the code and the event code indicating the alarm stop to the other house alarm device, the alarm indicating the interlock destination is stopped in step S59.

  Although FIG. 9 shows a sensor failure as an example, the same applies to a low battery failure detected when the power supply voltage from the battery power supply 40 drops below a predetermined voltage. Of course, the same applies to other obstacles.

  FIG. 10 is an explanatory diagram showing the contents of another embodiment of the relay management table 72 provided in the memory 46 of FIG. 3, in addition to registering a set of serial number and source code acquired from the received event signal, It is characterized in that different delay timings are registered in advance for each resident alarm device constituting the interlocking group.

  Delay timing is information that sets the time lag from receiving an event signal from another resident alarm to relay transmission. Even if multiple resident alarms receive an event signal at the same time, the delay timing can be set differently. The timing of relay transmission of event signals is made different from each other, and the probability of collision of event signals due to simultaneous relaying of a plurality of residential alarms is lowered.

  When the relay control unit 62 using the relay management table 72 of FIG. 10 receives an event signal from the interlocking source or the relay source alarm device by making the delay timing set here different for each home alarm device. The event signal is relayed and transmitted at a timing different from that of other alarm devices that are linked. For example, when the relay control unit 62 receives an event signal from the interlock source or the relay source alarm device, the relay control unit 62 relays the event signal at its own delay timing set in the relay management table 72 based on its own source code. To do.

  For example, the resident guard 10-1 registering the relay management table 72 of FIG. 10 has the transmission source code = 101, and therefore registers “1” at the end of the transmission source code = 101 in the delay timing. Yes. Since the transmission source code = 101 is a binary code, assuming that the maximum number of one group is 8, for example, the delay timing is determined and registered by the lower 3 bits, for example. The delay timing set in this way is multiplied by a predetermined unit time to perform time conversion, and then delay processing is performed.

  The method for determining the delay timing may be different from each other, and can be determined by an appropriate method such as round robin. Even if it is not necessarily different for all the house alarms, a predetermined effect can be obtained even if a part is different.

  FIG. 11 is a flowchart showing the relay control using the delay timing in steps S47, S52, and S58 of FIG. In FIG. 11, the relay control of the present embodiment acquires a set of serial numbers and transmission source codes from the event signal received in step S61, and whether or not the set matches the set registered in the relay management table 72 in step S62. If there is a discrepancy, the process proceeds to step S63, where a set of serial number and source code is registered in the relay management table 72. Then, the delay timing is acquired from the relay management table 72 in step S64, and the delay timing is obtained in step S65. Monitor the arrival of

  In the monitoring of the delay timing, a timer counter that counts up in a predetermined unit time is started and compared with the value of the delay timing, and the arrival of the delay timing is determined when they match. If it is determined in step S65 that the delay timing has been reached, the process proceeds to step S66 to relay and transmit the event signal.

  As a result, even if event signals from the transmission source or the relay source are received almost simultaneously by a plurality of residence police devices, the collision probability of the event signal due to the relay transmission can be reduced by shifting the timing of the relay transmission.

  If the set matches the registered group in step S62, the process proceeds to step S67 to end the relay.

  If event codes are also managed in the relay management table, relay management for each event as well as the source code becomes possible, so when one alarm device sends different events at the same time, etc. Communication traffic can be organized. At this time, the latest data may be stored for each event code in the relay management table.

  In addition, the above embodiment has been taken as an example of a residential alarm for fire detection, but in addition to this, an appropriate alarm for detecting various abnormalities such as a gas leak alarm and a security alarm The alarm stop process of the present embodiment can be applied as it is for each device. Moreover, it can be applied not only to residential use but also to various types of alarm devices such as buildings and offices.

  In addition, the processing related to the relay of the present invention is also applied to, for example, the master unit and the slave unit of the conventional interlocking alarm system in which the master unit and the slave unit are provided and the event information from the slave unit is linked via the master unit. It can also be applied, and it can also be applied to the linkage between parent machines of different groups.

  In the above embodiment, the alarm unit is provided with the sensor unit and the alarm output processing unit as an example. However, as another embodiment, the alarm unit has a separate sensor unit and alarm output processing unit. There may be.
