  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 inside the switch cover, an LED 22 for displaying an alarm is arranged as indicated by a dotted line. When the LED 22 lights up, the LED 22 is lit through the switch cover portion of the alarm stop switch 20 and the lighting state of the LED 22 is external. As you can see from.

  Further, a mounting hook 15 is provided on the upper 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 the screw is passed through the mounting hook 15, so that the home guard 10 can be installed on the wall surface. 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.

  FIG. 2 is an explanatory diagram showing an installation state of the alarm system of the present embodiment for a house. In the example of FIG. 2, there are residence alarm devices 10-1 to 10-4 for detecting and alarming the fire of this embodiment in each of the kitchen, living room, main bedroom, and child room provided in the house 24. The resident guard 10-5 is also installed in the garage 26 which is installed and is built outdoors.

  The home alarm devices 10-1 to 10-5 have a function of transmitting / receiving event signals to / from each other wirelessly, and perform fire monitoring of the entire house.

  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. When an event signal indicating a fire alarm is received from the other home alarm devices 10-1 to 10-3, 10-5, or the source home alarm device 10-4, as an interlock destination by an alarm sound and an alarm display The alarm action is performed.

  Here, as the alarm sound of the home alarm device 10-4 that has become the link source, for example, “Please confirm that the Woo fire alarm has been activated” is output by a voice message. On the other hand, in the interlocked residence alarm devices 10-1 to 10-3, 10-5, a voice message such as “Please confirm that another fire alarm has been activated” is output.

  Moreover, as a display accompanying the alarm of the residence police device 10-4 which became the interlocking | linkage origin, LED22 is lighted, for example. On the other hand, the LED 22 is blinked in the interlocked residence police 10-1 to 10-3, 10-5. Thereby, the alarm display by the LED 50 in the interlock source alarm and the interlock destination alarm can be distinguished.

  It should be noted that the interlocking source LED 22 may be blinking and the interlocking destination LED 22 may be lit, or the same LED 22 may be blinking or blinking or lit for both the interlocking source alarm and the interlocking destination alarm.

  If any of the alarm stop switches 20 is operated while the home alarm devices 10-1 to 10-5 are emitting an alarm sound, the alarm sound is stopped for the interlocking source and the interlocking destination. A stop process is performed in which the linkage source continues and the linkage destination stops.

  FIG. 3 shows the alarm stop in the present embodiment. FIG. 3 (A) shows that the house guard 10-1 among the house guards 10-1 to 10-5 that are linked to each other detects a fire, and the house guard 10-1 uses an alarm sound and the LED 22 as an alarm, for example. The fire alarm which shows the interlocking origin is performed by the accompanying lighting display, and the remaining dwelling devices 10-2 to 10-5 perform the fire alarm indicating the interlocking destination by the blinking display accompanying the alarm sound and the LED 22, for example.

  When one of the alarm stop switches 20 of the interlocking home alarm device 10-1 and the interlocking destination alarm devices 10-2 to 10-5 is operated in this interlocking alarm state, as shown in FIG. The alarm sound being performed by the interlocking home police 10-1 is stopped, but the display accompanying the alarm continues for at least a predetermined period, while the interlocking home police 10-2 to 10-5 is performed. The alarm sound indicating the linked destination and the display accompanying the alarm are all stopped.

  At this time, the lighting state is not necessarily maintained, it may be turned on again after a short time extinction, or, for example, the lighting display may be switched to the blinking display. It may be the same as the display during the alarm. It is sufficient that some kind of display is performed for at least a predetermined period after the alarm stop operation.

  When an interlocking alarm is performed in this way, any of the residential alarm devices 10-1 to 10-5 can be operated without going to each installation location of the residential alarm devices 10-1 to 10-5 and performing an alarm stop operation. The alarm stop operation of the home alarm stops all the alarm sounds of the link source and the link destination, the link source display associated with the alarm remains the same, and all the link destination displays associated with the alarm can be stopped. Simple and easy.

  In addition, even if any resident alarm warning stop operation is performed, the LED 22 on the interlocking source alarm device 10-1 continues to be lit with an alarm, for example, to identify the fire source after fire extinguishment, false alarm or non-fire alarm It is possible to easily and reliably identify the home alarm device that issued the alarm.

  The alarm display by the LED 22 of the interlocking home resident alarm 10-1 continuing after the alarm stop is stopped when a predetermined time determined by the timer setting elapses or when the next alarm stop operation is detected.

  FIG. 4 is an explanatory diagram showing, in a list format, alarm contents at the time of abnormality detection and alarm stop operation according to the present invention divided into linkage sources and linkage destinations.

  In FIG. 4, the alarm type of the interlocking source and the interlocking destination is an alarm sound and a display associated with the alarm. When an abnormality is detected, the interlocking source performs the interlocking source alarm sound and a lighting display associated with the alarm. When an abnormality is detected, the linkage destination displays a linkage destination alarm sound and a flashing display associated with the alarm.

  When an alarm stop operation by the alarm stop switch 20 is detected in any house alarm in the alarm state of the interlock source and the interlock destination based on this abnormality detection, the alarm sound of the interlock source stops and the alarm display continues. . The continuous alarm display may be any of lighting, blinking, and blinking. On the other hand, the interlocking destination stops the alarm sound and the display accompanying the alarm.

  FIG. 5 is a block diagram showing an embodiment of a residential alarm provided in the alarm system of FIG. 2, and the five residential alarms 10-1 to 10-5 shown in FIG. The circuit configuration of the device 10-1 is shown in detail. The other residential alarm devices 10-2 to 10-5 have the same configuration.

  Although the arrow which connects the residence guard 10-1 and the other residence guards 10-2 to 10-5 has shown that each communicates, for example, the residence guard 10-2 and the residence guard 10-3 And so on. Of course, the present invention can be applied even if communication is performed only through the path indicated by the arrow in FIG.

  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 recording circuit unit (memory) 32, a sensor unit 34, and a notification unit 36. An operation unit 38 and a battery power source 40 are provided.

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

  Of course, the wireless communication unit 30 has contents conforming to the standard of the assigned wireless station in the area in places other than Japan.

  The memory 22 as a storage unit includes a serial number 48, which is a serial number indicating the order of the vent signals, a transmission source code 50 serving as an ID (identifier) for identifying a residential alarm, and a residence installed in a house as shown in FIG. The group code | symbol 52 for comprising the interlocking | linkage group which performs interlocking | linkage alarm with the alarm devices 10-1 to 10-5 is stored.

  The serial number 48 is for managing the relay processing of the event signal in the communication between the alarm devices, but will not be described in detail because it is not directly related to the present invention.

  As the transmission source code 50, 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. As the transmission source code 50, for example, a serial number of a house alarm is used.

  The group code 52 is a code that is set in common to a plurality of house alarms constituting the interlocking group, and the group code included in the event signal from another house alarm received by the wireless communication unit 30 is registered in the memory 32. When this event signal matches the group code 52, the event signal is received and processed as a valid signal. Interference can be avoided.

  The sensor unit 34 is provided with a smoke detector 16 that detects smoke and outputs a signal.

  In addition to the smoke detector 16, the sensor unit 34 may be provided with a temperature detection element such as a thermistor for detecting the temperature due to a fire, and various elements for detecting other physical phenomenon changes associated with the fire.

  The notification unit 36 is provided with a speaker 58 that outputs an alarm sound and an LED 22 that performs display associated with the alarm. 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. Instead of the speaker 48, a buzzer or the like may be used.

  The operation unit 38 is provided with an alarm stop switch 20. The alarm stop switch 20 is effective as an alarm stop switch only when a warning sound from the notification unit 36 is displayed by the speaker 48 or a display accompanying the alarm is performed by the LED 22. If the alarm stop switch 20 is operated while the alarm sound indicating the interlock source is output, the alarm sound is stopped and the display accompanying the alarm is continued. On the other hand, if the alarm stop switch 20 is operated during the alarm indicating the interlock destination, the alarm sound is displayed. Stops and the display accompanying the alarm also stops.

  On the other hand, the alarm stop switch 20 functions as an inspection switch in the normal monitoring state in which the fire alarm indicating the interlocking source or the interlocking destination is not performed, and when the inspection switch is pressed in this state, a predetermined inspection operation is executed and the notification unit 36 is operated. A voice message indicating the inspection result is output from.

  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 an event detection unit 60, a transmission processing unit 62, a reception processing unit 64, an alarm processing unit 66, and an alarm stop unit 68 as functions realized by executing the program.

  The event detection unit 60 detects an event including abnormality detection by the sensor unit 34, alarm stop by the operation unit 28, and abnormality recovery in which the abnormality detection of the sensor unit 24 disappears.

  The transmission processing unit 62 detects an event indicating a detected event when the event detection unit 60 detects an event including an abnormality detection by the sensor unit 34, an alarm stop by the operation unit 38, and an abnormality recovery that eliminates the abnormality detection of the sensor unit 34. The signal is sent to the linked house police. The reception processing unit 64 receives and decodes the event signals from the residential alarm devices 10-2 to 10-5.

  The alarm processing unit 66 outputs an alarm sound indicating the interlocking source from the speaker 58 when the event detecting unit 60 detects a fire as its own abnormality, and drives the LED 22 to display the interlocking source. An event signal indicating the alarm is transmitted to another house alarm.

  More specifically, the alarm processing unit 66 operates in conjunction with the speaker 58 of the notification unit 36 when the event detection unit 60 detects a fire based on the smoke detection signal from the smoke detection unit 16 provided in the sensor unit 34. Alarm sound indicating the origin, for example, “Woo Woo fire alarm activated Please confirm” is output repeatedly, LED22 blinks to display the alarm indicating the interlock source, and an event signal indicating fire alarm The transmission circuit 42 of the wireless communication unit 30 causes the antenna 31 to transmit to the other mortgages 10-2 to 10-5.

  Further, the alarm processing unit 66 receives an event signal indicating a fire from any of the other residential alarm devices 10-2 to 10-5 by the reception circuit 44 of the wireless communication unit 30, and becomes effective in the reception processing unit 64. Sometimes, an alarm sound indicating the link destination is repeatedly output from the speaker 58 of the notification unit 36, for example, “Woooo Please check if another fire alarm has been activated”, and the LED 22 blinks simultaneously. Is displayed.

  When the alarm stop unit 68 detects an alarm stop operation of the alarm stop switch 20 provided in the operation unit 38 during the output of the abnormal alarm sound indicating the interlock source, an alarm sound from the speaker 58 indicating the interlock source, for example, “Woo Woo Fire” “Alarm unit has been activated, please confirm” is stopped, the alarm display by turning on LED 22 is continued, and an event signal indicating the alarm stop is transmitted to other dwelling units 10-2 to 10-5.

  In addition, when the alarm stop unit 68 detects reception of an event signal indicating an alarm stop from another house alarm device during output of an abnormal alarm sound indicating the interlock source, similarly, an alarm from the speaker 58 indicating the interlock source is detected. Sounds such as “Woo Woo fire alarm activated Please check” are stopped and the alarm display by turning on the LED 22 is continued.

  In addition, the alarm stop unit 68 displays a display associated with an alarm indicating an interlocking source that has been continued by detection of an event signal indicating an alarm stop operation of the own alarm or an alarm stop from another dwelling device, or a self-alarm. Stop when a stop operation is detected.

  Further, the alarm stop unit 68 detects an alarm sound from the speaker 58 indicating the interlock destination, for example, “Woo-woo” when detecting the reception of the event signal indicating the alarm stop from another house alarm device during the output of the abnormal alarm sound indicating the interlock destination. “Check that another fire alarm has been activated”, and stop blinking the LED22 alarm.

  FIG. 6 is an explanatory diagram showing the format of the event signal used in this embodiment. In FIG. 6, the event signal 46 includes a serial number 48, a transmission source code 50, a group code 52, and an event code 54.

  The serial number 48 is a serial number indicating the order of event signals, and is incremented by one each time an event signal is transmitted. In addition, the serial number 48 is generated asynchronously in each of the residential alarm devices 10-1 to 10-5. The serial number 48 is for managing the relay processing of the event signal in the communication between the alarm devices, but will not be described in detail because it is not directly related to the present invention.

  The transmission source code 50 is a 26-bit code, for example. The group code 52 is an 8-bit code, for example, and the same group code is set for, for example, the residential alarm devices 10-1 to 10-5 in FIG.

  In addition, as the group code 52, in addition to setting the same group code to the same group of house alarms, a reference code common to the house alarms constituting a predetermined group, and a transmission source unique to each house alarm A different group code may be used for each residential alarm obtained from the calculation with the code.

  The event code 54 is a code representing the event content such as fire and gas leak. In the present embodiment, a 3-bit code is used. For example, “001” indicates a fire, “010” indicates a gas leak, “ “011” indicates theft, “100” stops the alarm, “101” recovers, and the rest is reserved. The number of bits of the event code 54 can be further increased to 4 bits and 5 bits to represent more event contents.

  FIG. 7 is a flowchart showing an example of the fire monitoring process in the residential alarm device 10-1 in FIG. 4, which is a process by executing the program of the processor 28.

  In FIG. 7, the fire monitoring process monitors the fire occurrence in step S1, and if the smoke detection signal output from the sensor unit 34 exceeds a predetermined fire level, the fire occurrence is determined and the process proceeds to step S2. After transmitting the event signal including the event code indicating the number, the transmission source code, the group code, and the fire to the other home alarm device by radio, the alarm source from the speaker 58 and the display by turning on the LED 22 in step S3 A fire alarm indicating is output.

  Subsequently, in step S4, it is determined whether or not there is a fire restoration in which the smoke detection signal from the sensor unit 34 is reduced and the fire disappears. If the fire continues, an alarm stop operation by the alarm stop switch 20 is performed in step S5. 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 S6. In addition, while the fire is continuing, the transmission of the event signal indicating the fire is repeated every predetermined time.

  During the processing cycle of steps S4 to S6, when the smoke detection signal from the sensor unit 34 decreases and the fire disappears, the fire recovery is determined in step S4, and the serial number, the transmission source code, the group code, and the fire recovery are determined in step S7. An event signal including the event code to be transmitted is transmitted to the other home alarm device, and the process proceeds to step S9 to stop the alarm sound indicating the interlocking source, and the display accompanying the alarm is continued. Instead of stopping the alarm sound of the interlocking source in step S9 and continuing the display accompanying the alarm, the process proceeds to step S11 to stop the alarm sound of the interlocking source and the alarm display and return to the normal monitoring state. Anyway.

  When the alarm stop operation by the alarm stop switch 20 is determined in step S5, the process proceeds to step S8, and an event signal including a serial number, a transmission source code, a group code, and an event code indicating an alarm stop is transmitted to another house alarm. Then, the process proceeds to step S9, the alarm sound from the speaker 58 indicating the interlock source is stopped, and the lighting display accompanying the alarm of the LED 22 is continued as it is.

  If it is determined in step S6 that an alarm stop event signal has been received from another residential alarm device, the process proceeds to step S9 to stop the alarm sound from the speaker 58 indicating the interlocking source, and the lighting display associated with the alarm of the LED 22 is continued as it is. .

  In this embodiment, the display indicating the interlocking source that is continuing in response to the event signal indicating the stop operation of the own alarm or the stop of the alarm from another dwelling unit in step S9 is the elapse of a predetermined time in step S10. When it is determined, the process proceeds to step S11 to stop the alarm sound and the alarm display indicating the interlocking source.

  In addition, instead of the predetermined time elapse by the timer setting in step S10, when an alarm stop operation by the alarm stop switch 20 is detected, the alarm display indicating the interlocking source may be stopped.

  On the other hand, if it is not a fire in step S1, it is determined in step S12 whether or not an event signal has been received from another residential alarm. When it is determined that an event signal indicating a fire from another house alarm is detected, the process proceeds to step S13, where a warning sound from the speaker 58 and a blinking LED 22 are displayed as a fire alarm indicating the link destination.

  Next, in step S14, it is determined whether or not an event signal indicating an abnormality (fire) recovery from another home alarm is received, and when an event signal indicating an abnormality recovery is received, the process proceeds to step S15 and the speaker indicating the interlocking destination. The alarm sound from 58 and the blinking display of the LED 22 are stopped.

  If no event signal indicating abnormality recovery is received in step S14, it is checked in step S16 whether or not an event signal indicating an alarm stop is received from another residential alarm, and an event signal indicating an alarm stop is received. If it discriminate | determines, it will progress to step S18 and will stop the display by the alarm sound from the speaker 58 which shows an interlocking | linkage destination, and blinking of LED22.

When there is no event signal reception indicating an alarm stop in step S16, it is determined whether or not an alarm stop operation is performed by the alarm stop switch 20 in step S17.
In step S18, an event signal including a serial number, a transmission source code, a group code, and an event code indicating an alarm stop is transmitted to another house alarm device. Then, the process proceeds to step S19 and an alarm sound from the speaker 58 indicating the interlocking destination The display by the blinking of the LED 22 is stopped.
