Description

The present invention relates to an alarm device and an alarm system that detect and alarm an abnormality such as a fire or a gas leak and relay and transmit a signal to another alarm device to output an alarm in conjunction.

  Conventionally, residential alarms (hereinafter referred to as “residential alarms”) that detect and warn of fires in houses have become widespread. In recent years, a plurality of residential alarms can communicate with each other to provide a single residence. Wireless dwelling alarms for linked alarm systems that can alarm alarm information with other alarms have been put into practical use, and some of these operate by battery power.

  In a linked alarm system that performs wireless communication, if a fire is detected by a certain home alarm, the home alarm that detected the fire is, for example, “Woo Woo Fire Alarm has been activated. Please send a voice message saying "Please," while the linked house alarm outputs a voice message saying "Check if a fire alarm for each Woo has been activated". In addition, the alarm lamp of the interlocking house police is blinking, the alarm lamp of the interlocking house police is blinking, and the interlock source or the interlock destination can be distinguished from the display of the alarm lamp.

  On the other hand, there are cases where a house is equipped with a gas leak alarm device, a CO alarm device, and various crime prevention alarm devices in addition to a home alarm device that detects and alerts a fire.

Explanatory drawing which showed the format of the event signal used in embodiment of FIG. The block diagram which showed embodiment of the gas leak alarm device which detects and alarms about the gas leak provided in the alarm system of FIG. The flowchart which showed the fire monitoring processing with the house alarm of FIG. The flowchart which showed the fire monitoring processing by the gas leak alarm of FIG.

  FIG. 1 is an explanatory diagram showing an installed state of the alarm system of the present embodiment for a house. In the example of FIG. 1, the residential alarm devices 10-1 to 10-10 for detecting and alarming the fire of the present embodiment in each of the kitchen, living room, main bedroom, children's room, and garage 16 provided in the house 14. In addition, gas leak alarms 12-1 to 12-3 are installed in the kitchen, living room, and main bedroom as different types of alarms. The types of alarm devices installed at each location vary depending on the environment of the target location, the circumstances of the user, etc., but for the sake of simplicity, the above example is used here.

  Each of the house alarm devices 10-1 to 10-5 and the gas leak alarm devices 12-1 to 12-3 has a function of wirelessly transmitting and receiving event signals to each other, and performs fire monitoring and gas leak monitoring of the installation site. ing.

  In the present embodiment, the group G1 is constituted by the residential alarm devices 10-1, 10-2, 10-5 and the gas leak alarm devices 12-1, 12-2 installed on the first floor of the house 14 and the garage 16. By configuring the other group G2 with the housing alarm devices 10-3, 10-4 and the gas leak alarm device 12-3 installed on the second floor of the house 14, and transmitting the event signal including its own group code, It receives and processes event signals belonging to its own group and other groups linked to its own group.

  As described above, the groups G1 and G2 can form a group in which alarm devices for detecting and alarming different types of abnormalities such as fire and gas leakage are mixed. The reason why the group is constructed in this manner is to avoid unnecessary interlocking caused by transmission / reception of radio signals to / from a home alarm device or alarm device installed in a neighboring residence or the like.

  The group G1 residence alarm devices 10-1, 10-2, 10-5 and the gas leak alarm devices 12-1, 12-2 have a group code G1 of the group to which the storage unit belongs and a group G1 of the group G1. By storing the cooperation group code G2 for cooperation, event signals from the group G1 to which the self belongs and a different group G2 can be received.

  Similarly, the house alarm devices 10-3 and 10-4 and the gas leak alarm device 12-3 of the group G2 are used for coordinating with the group code G2 of the group to which the storage device belongs and the group G2 of the group G2. By storing the cooperation group code G1, it is possible to receive and process event signals from the group G2 to which the group belongs and a different group G1.

  If a fire has occurred in the child's room of the house 14 now, 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 home alarm device 10-4 is triggered, the home alarm device 10-4 functions as an interlocking source, and the other residential alarm devices 10-1 to 10-3, 10-5 and the gas leak alarm device 12 to be interlocked. -1 to 12-3 wirelessly transmit an event signal including its own group code G2, an event code indicating an abnormal fire type, and an on / off code indicating alarm on. In the other residence guard 10-3 and the gas leak alarm 12-3 belonging to the same group G2 as the residence guard 10-4, the self group code G2 from the linkage origin residence guard 10-4, the fire When an event signal including an event code indicating an alarm ON and an ON / OFF code indicating alarm ON is received, a fire alarm as an interlocking destination is output.

  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, at the interlocked residence alarm device 10-3 and the gas leak alarm device 12-3, a voice message such as “Please confirm that another fire alarm device has been activated” is output.

  On the other hand, in the resident alarm devices 10-1, 10-2, 10-5 and the gas leak alarm devices 12-1, 12-2 belonging to the group G1 different from the resident alarm device 10-4 that transmitted the event signal, the interlocking is performed. When receiving the event signal including the group code G2, the event code indicating the fire, and the on / off code indicating the alarm on from the original residence guard 10-4, the cooperation group code G2 stored in the storage unit By determining the coincidence, it is received as a valid event signal, and a fire alarm is output as a linkage destination.

  At this time, fire alarms linked to the housing alarms 10-1, 10-2, 10-5 and the gas leak alarms 12-1, 12-2 were confirmed as the fire alarms by Wu Wu operated. Please output a voice message.

  Further, when a gas leak alarm 12-1 installed in, for example, a kitchen of the house 14 detects a gas leak and gives an alarm, the gas leak alarm 12-1 functions as an interlocking source, and its own group code G1, gas leak And an event signal including an event code indicating that the alarm is on and an on / off code indicating that the alarm is on are transmitted by radio.

  In the residence alarm devices 10-1, 10-2, 10-35 and the gas leakage alarm device 12-2 belonging to the same group G1 as the gas leakage alarm device 12-1 that transmitted the event signal, the interlocking source gas leakage alarm device When an event signal including the self group code G1 from 12-1, an event code indicating gas leak, and an on / off code indicating alarm on is received, a gas leak alarm as an interlocking destination is output.

  On the other hand, in the residential alarm devices 10-3 and 12-4 and the gas leak alarm device 12-3 belonging to the group G2 different from the gas leak alarm device 12-1 that transmitted the event signal, the interlocking source gas leak alarm device 12 is provided. -1 to receive the event signal indicating the gas leak alarm ON including the group code G1, by determining the coincidence with the cooperation group code G1 stored in the storage unit, is received as an effective event signal, A gas leak alarm is output as a link destination.

  Here, as an alarm sound of the gas leak alarm device 12-1, which has become the linkage source, for example, a voice message “Please confirm that the pyropyro gas leak alarm has been activated” is output. On the other hand, for the gas leak alarm devices 12-2 and 12-3 and the residential guard devices 10-1 to 10-5 that are linked to, please check that the gas leak alarm device has been activated. Output a voice message.

  When the alarm stop switch is operated in a state where the house alarm devices 10-1 to 10-5 and the gas leak alarm devices 12-1 to 12-3 are outputting an alarm sound, an alarm 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) If any alarm stop switch other than the interlock source is operated among the residential alarm devices 10-1 to 10-5 and the gas leak alarm devices 12-1 to 12-3, only the interlock source continuously outputs an alarm sound. The interlocking destination stops the alarm sound. On the other hand, when the interlocking source alarm stop switch is operated, all alarm sounds of the interlocking source and the interlocking destination are stopped.

  (2) If you operate any alarm stop switch among the alarm devices 10-1 to 10-5 and the gas leak alarm devices 12-1 to 12-3 during the alarm, all of them regardless of the link destination and link source Stop the alarm sound.

  (3) The stop process in (1) is the first mode, and the stop process in (2) is the second mode, and either one of the modes is selected to perform the stop process.

  In addition, if the residence police and gas leak alarms include those that have a relay function, or if a repeater is installed separately from the residence guard and alarm, the linked residence guard and alarm are relayed. The above processing may be performed according to the event signal.

  The group code and the cooperation group code do not need to be one common code common to the group or the cooperation group, and may be different codes (values and symbols). That is, any group can be used as long as it can identify and manage the group by some method such as arithmetic processing based on the received group code. As described above, the validity / invalidity determination of the event signal is not necessarily based on the matching and matching, and other rational determination methods can be used.

  FIG. 2 is a block diagram showing an embodiment of a residential alarm provided in the alarm system of FIG. FIG. 2 shows in detail the circuit configuration of the five home guards 10-1 to 10-5 shown in FIG.

  The arrows connecting the home alarm device 10-1, the other home alarm devices 10-2 to 10-4, and the gas leak alarm devices 12-1 to 12-3 indicate that they communicate with each other. The alarm device 10-2 and the residence alarm device 10-5, the residence alarm device 10-2, the gas leak alarm device 12-3, and the like are also allowed to communicate with each other.

  Of course, the present invention can also be applied to a system in which communication is performed only through the path indicated by the arrow in FIG. For example, the home guard 10-1 and the home guard 10-3 may be set as the parent devices of the group G1 and the group G2, respectively, and the inter-group cooperation may be linked only between the parent devices of each group. And you may make it comprise the same kind of house alarm device or alarm device which comprises one group. In this way, it is possible to obtain an advantage that the system configuration can be easily grasped. An example of this case will be described below.

  The home guard 10-1 includes a processor 18 known as a one-chip CPU. For the processor 18, a wireless communication unit 20 including an antenna 21, a recording circuit unit (memory) 22, a sensor unit 24, and a notification unit 26. An operation unit 28 and a battery power source 30 are provided.

  The wireless communication unit 20 is provided with a transmission circuit 32 and a reception circuit 34, and event signals are wirelessly transmitted between the other residential alarm devices 10-2 to 10-4 and the gas leak alarm devices 12-1 to 12-3. You can send and receive. As the wireless communication unit 20, in Japan, for example, STD-30 (a wireless equipment standard for a low power security system wireless station) or STD-T67 known as a standard for a specific low power wireless station in the 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 20 has contents conforming to the standard of the assigned wireless station in the area in places other than Japan.

  In the memory 22 as a storage unit, a serial number 38 which is a serial number indicating the order of the vent signals, a transmission source code 40 serving as an ID (identifier) for identifying a residential alarm, and a residential alarm 10-1 to 10-4. The group code 42 for configuring the group G1 that performs the linked alarm in the group, the linked group code 46 for coordinating the alarm with the other group G2 that performs the linked alarm in the gas leak alarm devices 12-1 to 12-3, the fire , An event code 45 indicating the type of abnormality such as gas leakage, and second abnormality alarm information 47 used for determining effective reception of an alarm-on event signal from the cooperation group and issuing a gas leakage alarm are stored. Yes.

  As the transmission source code 40, 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.

  According to the domestic wireless standard, the transmitting terminal is required to add a code that can identify the transmission source to the transmission signal, and the transmission source code 40 is also used for the purpose of responding to this. As the transmission source code 40, for example, a serial number of a residential alarm or an alarm device is used.

  The group code 42 is a code that is commonly set for a plurality of house alarms and alarm devices that constitute the same group, and is included in event signals from other house alarm devices and alarm devices received by the wireless communication unit 20. When the group code matches the group code 42 registered in the memory 22, this event signal is received as a valid signal and processed.

  The cooperation group code 46 is a code indicating at least one other cooperation group that cooperates with the group to which the user belongs (group code of the group that is the partner with which the cooperation is performed). When the group code included in the event signal from the alarm device or alarm device matches the cooperation group code 46 registered in the memory 22, this event signal is received and processed as a valid signal.

  The second abnormality alarm information 47 received an event signal including a group code, an event code, and an on / off code from the gas leak alarm devices 12-1 to 12-3 which are different types of alarm devices belonging to the same group G1 or the cooperation group G2. Information used to output a second abnormality alarm (gas leak alarm) that is different from the first abnormality (fire) to be detected by itself, for example, as a voice message output from the speaker 52, for example, “ Voice data indicating that another gas leak alarm has been activated is stored.

  By storing the second abnormality alarm information 47 in the memory 22 in this way, when an event signal for abnormality detection from a different type of alarm device is received, a gas leakage alarm that is a different type of abnormal alarm can be output. it can.

  It is possible to manage and control not only the voice message but also the type of display alarm corresponding to the cooperation group code and event type.

  Further, instead of voice messages, alarms can be distinguished by buzzer sounds having different periods, amplitudes, timbres, and the like, and at this time, a buzzer can be used instead of the speaker 52 described later.

  By such a method, the first abnormality alarm, the second abnormality alarm, the alarm as the interlock source, and the alarm as the interlock destination are optimally performed.

  In the present embodiment, the sensor unit 24 is provided with a smoke detector unit 50. The smoke detector 50 outputs a detection signal when smoke flows in. The detection signal from the smoke detector 50 is captured by the processor 18 (AD conversion), and when the processor 18 side exceeds a predetermined fire level, a fire alarm is determined, and the detection signal from the smoke detector 50 decreases. Therefore, it is determined that there is no fire alarm (fire recovery) by falling below the fire level. In addition to the smoke detector 50, the sensor unit 24 may be provided with a temperature change detection element such as a thermistor for detecting a temperature due to a fire, and various elements for detecting other physical phenomenon changes due to a fire.

  The notification unit 26 is provided with a speaker 52 and an LED 54. The speaker 52 outputs a voice message and an alarm sound from a voice synthesis circuit unit (not shown). The LED 54 displays an abnormality such as a fire by blinking, blinking, or lighting.

  The operation unit 28 is provided with an alarm stop switch 56. When the alarm stop switch 56 is operated, the alarm sound flowing from the home alarm device 10-1 can be stopped. In the present embodiment, the alarm stop switch 56 is also used as an inspection switch for instructing start of inspection of the internal function and state of the home alarm device 10-1. The alarm stop switch 56 is effective only when an alarm is output from the notification unit 26 through the speaker 52. On the other hand, the alarm stop switch 56 functions as an inspection switch in a normal monitoring state where no alarm is output. When the alarm stop switch is pressed in this state, a predetermined inspection operation is executed and a sound indicating the inspection result is sent from the notification unit 26. Messages are output.

  The battery power source 30 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 20 in the residential alarm 10-1. The battery life of the year is guaranteed.

  The processor 18 is provided with an event detection unit 58, a transmission processing unit 60, a reception processing unit 62, and an alarm processing unit 64 as functions realized by executing the program.

  The event detection unit 58 detects an event including abnormality detection by the sensor unit 24, 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 60 is stored in the memory 22 when the event detection unit 58 detects its own event including abnormality detection by the sensor unit 24, alarm stop by the operation unit 28, and abnormality recovery that eliminates abnormality detection of the sensor unit 24. Then, an event signal including the group code 42 to which the user belongs, the event code 45 indicating the type of event, and the on / off code indicating event on or off is transmitted to the interlocking alarm device.

  The reception processing unit 62 receives and decodes event signals from the residential alarm devices 10-2 to 10-5 or the gas leak alarm devices 12-1 to 12-3.

  The alarm processing unit 64 outputs a fire alarm as a first abnormality alarm when the event detection unit 58 detects a fire alarm as its own abnormality, and the reception processing unit 62 outputs another fire alarm 10-2 to 10-. 5 or when the event signal from the gas leak alarm device 12-1 to 12-3 is received, the group code 42 of the other alarm device included in the event signal is stored in the memory 22 or linked. When it is determined whether or not it matches the group code 46, and it is determined that it matches any of them, the event type by the event code 42 is recognized, and if the on / off code is ON, the type of abnormality is supported. The fire alarm as the interlock destination that is the first abnormality alarm is output, or the gas leak alarm as the interlock destination that is the second abnormality alarm is output based on the second abnormality alarm information 47.

  In this case, the fire alarm that is the first abnormality alarm and the gas leak alarm that is the second abnormality alarm are acoustic alarms such as a voice message by the speaker 52 provided in the notification unit 26 and lighting, blinking, and blinking of the LED 54. Alarm display.

  Further, when the event detection unit 58 detects that its own fire has been generated, the alarm processing unit 64 is configured to perform the first operation based on the event signal received from the gas leak alarm devices 12-1 to 12-3 that are alarm devices of the cooperation group. Prior to the gas leakage alarm as the second abnormality alarm, a fire alarm is performed as the first abnormality alarm by the fire alarm detected by the event detection unit 58.

  This priority relationship can be set in an appropriate order in consideration of the type of alarm, the installation / operation environment, the user's request, etc., and in some cases, the second abnormality information can be prioritized, or an acoustic alarm It is also possible to make the priority order in the display different from the display priority order.

  Also, the alarm processing unit 58 is a fire alarm and a second abnormality alarm that are first abnormality alarms, for example, according to the storage addresses of its own group code 42 and linkage group code 46 stored in the memory 22. The priority of the gas leak alarm may be determined, and a high priority alarm may be output.

  Furthermore, instead of giving priority to the fire alarm by the self-fire alarm as a warning when the self-fire alarm and the event signal reception from the gas leak alarm occur in parallel, the fire detected by the event detector 58 A fire alarm is output as a first abnormality alarm based on the notification, and a gas leakage alarm is output in order so as not to overlap as a second abnormality alarm based on an event signal received from the gas leakage alarm device. Anyway.

  An example of an audio alarm will be described in detail. The alarm processing unit 64 starts from the speaker 52 of the notification unit 26 when the event detection unit 58 determines a fire from the detection signal of the smoke detection unit 50 provided in the sensor unit 24. The alarm sound indicating the link source, for example, “Woo Woo fire alarm activated Please confirm” is repeatedly output, the group code 42 indicating the group to which the user belongs, the event code 45 indicating fire, and the ON / OFF code for alarm ON Is transmitted from the antenna 21 to the other residential alarm devices 10-2 to 10-5 and the gas leak alarm devices 12-1 to 12-3 by the transmission circuit 32 of the wireless communication unit 20.

  Further, the alarm processing unit 64 generates an event signal indicating a fire or gas leak / on (alarm on) from any of the other residential alarm devices 10-2 to 10-5 or the gas leak alarm devices 12-1 to 12-3. When received by the reception circuit 34 of the wireless communication unit 20 and enabled by the reception processing unit 62, if a fire occurs from the speaker 52 of the notification unit 26, an alarm sound that becomes a first abnormality alarm indicating the interlocking destination, for example, “ Repeatedly output a voice message saying “Woo Woo another fire alarm has been activated”, and if it is a gas leak, a second abnormal alarm sound indicating the linkage destination, for example “Piropiro Piro another gas leak alarm is activated. Repeatedly output a voice message that says “Please confirm”.

  Here, when the alarm processing unit 64 outputs a fire alarm or gas leak interlocking source alarm sound, for example, the LED 54 of the notification unit 26 blinks, while when the alarm destination alarm sound is output, the LED 54 of the notification unit 26 is emitted. Blinks. Thereby, the display of the LED 54 in the interlocking source alarm and the interlocking destination alarm can be distinguished. Of course, the same LED 54 may be blinking, blinking, or lit for both the interlocking source alarm and the interlocking destination alarm.

  Then, a fire alarm (acoustic / display) as a first alarm to be detected by itself and a gas leak alarm (acoustic) as a second alarm upon receiving a gas leak event signal different from that to be detected by itself / Display) is different. Of course, an LED that performs display associated with the second alarm can be provided separately from the LED 54 that performs display associated with the first alarm.

  Further, the alarm processing unit 64 detects the operation source output from the speaker 52 when the event detection unit 58 detects the operation of the alarm stop switch 56 provided in the operation unit 28 during the output of the alarm sound indicating the operation source. The alarm signal which is the first abnormality alarm to be stopped is stopped, and the event signal including the self group code, the event code indicating the fire, and the on / off code of the alarm off is transmitted from the transmission circuit 32 of the wireless communication unit 20 to the other residential alarm device. 10-2 to 10-4 and the gas leak alarms 12-1 to 12-3, and the interlocking destinations in the other residential alarms 10-2 to 10-4 and the gas leak alarms 12-1 to 12-3 Stop the alarm sound.

  In this case, the alarm sound indicating the interlocking source output from the speaker 52 is stopped, the display of the LED 54 is held for at least a predetermined period, and an event signal for alarm OFF is transmitted from the transmission circuit 32 of the wireless communication unit 20 to another dwelling alarm device. 10-2 to 10-5 and the gas leak alarms 12-1 to 12-3, and the linked destinations in the other residential alarm devices 10-2 to 10-5 and the gas leak alarms 12-1 to 12-3 It is also possible to stop the alarm sound and leave only the display of the link source. In this way, it becomes easy to specify an abnormality detection source (abnormality occurrence location) by confirming later as a report history. Of course, other alarm stop patterns can be taken.

  Further, the alarm processing unit 64 stops the alarm (fire / off) from the other residential alarm devices 10-2 to 10-5 or the gas leak alarm devices 12-1 to 12-3 during the output of the alarm sound indicating the interlock destination. When the event signal shown is received by the receiving circuit 34 of the wireless communication unit 20 and is enabled by the reception processing unit 62, the alarm sound indicating the linkage destination is stopped.

  Further, the alarm processing unit 64 stops the interlocking source alarm and returns to a normal state when the event detection unit 58 detects an abnormal recovery in which the fire is not detected due to the absence of smoke from the smoke detection unit 46 provided in the sensor unit 24. At the same time, the transmission processing unit 62 sends an event signal including its own group code, an event code indicating a fire, and an on / off code indicating an alarm off state from the transmission circuit 32 of the wireless communication unit 20 to the resident alarm device 10- 2-10-5 and the gas leak alarm devices 12-1 to 12-3, on the other hand, any of the other residential alarm devices 10-2 to 10-5 and gas leak alarm devices 12-1 to 12-3 When the event signal indicating the alarm stop (fire / off) based on the fire recovery is received by the reception circuit 34 of the wireless communication unit 20 and becomes effective in the reception processing unit 62, the fire alarm at the linked destination is stopped and the normal operation is stopped. Condition Back to.

  As a result, when the interlocking source alarm is issued by the home alarm device 10-1, when it is confirmed that the alarm is caused by smoke other than fire by on-site confirmation, or when the cause of the fire is removed early by appropriate measures, etc. If you blow in from the smoke inlet of the smoke detector 50 and let out the smoke, the fire detection signal from the sensor unit 24 disappears, the alarm sound of the interlocking source automatically stops and normal Can be restored to the monitoring state.

  Also, the alarm processing unit 64 outputs an event signal indicating an alarm stop (gas leak / off) based on the gas leak recovery from the gas leak alarm device 12-1, for example, from the gas leak alarm unit 12-1 during the output of the gas leak alarm serving as the interlocking destination. When the signal is received by the receiving circuit 34 and enabled by the reception processing unit 62, the gas leakage alarm as the interlocking destination is stopped and returned to the normal state.

  FIG. 3 is an explanatory diagram showing the format of the event signal used in this embodiment. In FIG. 3, the event signal 36 includes a serial number 38, a transmission source code 40, a group code 42, an on / off code 44, and an event code 45. The transmission source code 40 is an individual ID that identifies the residential alarm or alarm device that transmitted the event signal, and is required by the standard or the like to be added to a signal transmitted from a domestic wireless device. Here, for example, the serial number of each house alarm or alarm is used.

  The serial number 38 is a serial number indicating the order of event signals, and is incremented by one each time an event signal is transmitted. The serial number 38 is generated asynchronously in each of the residence alarm devices 10-1 to 10-5 and the gas leak alarm device 12.

  The serial number 38 is used to manage the relay processing of the event signal in the communication between alarm devices, but will not be described in detail because it is not directly related to the present invention.

  The transmission source code 40 is a 26-bit code, for example. The group code 42 is, for example, an 8-bit code, and is different for each group, for example, the residential alarm devices 10-1 to 10-4 and the gas leak alarm device 12 shown in FIG. A sign is set.

  As the group code 42, in addition to setting the same group code for the same group of house alarms, a reference code common to the house alarms constituting a 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 on / off code 44 is an on / off code indicating whether the alarm is on or off. When the event detection unit 58 detects a fire alarm, the on / off code 42 is set to alarm on and the event detection unit 58 recovers the fire alarm. When the alarm is stopped by operating the alarm stop switch 28, the on / off code 42 is set to alarm off.

  The event code 45 is a code indicating the type of abnormality such as a fire or gas leak. In this embodiment, a 3-bit code is used. For example, “001” indicates a fire, “010” indicates a gas leak, “011” is stolen and the rest is reserved. The number of bits of the event code 42 can be further increased to 4 bits and 5 bits when the types of events are increased, thereby representing a plurality of types of event contents.

  FIG. 4 is a block diagram showing an embodiment of the gas leak alarm 12-1 provided in the alarm system of FIG.

  The gas leak alarm device 12-1 includes a processor 118. For the processor 118, a wireless communication unit 120 including an antenna 121, a memory 122, a sensor unit 124 that detects gas leak, a notification unit 126, an operation unit 128, and a battery. A power supply 130 is provided.

  The wireless communication unit 120 is provided with a transmission circuit 132 and a reception circuit 134. The memory 122 includes a serial number 38 which is a serial number added to the event signal, a transmission source code 40 serving as its own ID (identifier), a group code 42 indicating its own group, an event code 45 indicating the type of abnormality, A fire that is different from the self-detection target from the cooperation group code 46 (in this case, the code indicating G2) to which the home police devices 10-1 to 10-4 that cooperate with the group G1 belong, and the cooperation group G2 2nd abnormality alarm information 147 used for the alarm output by the event signal reception discrimination | determination which shows alerting is stored.

  The notification unit 126 is provided with a speaker 152 and an LED 154, and the operation unit 128 is provided with an alarm stop switch 156. A buzzer can be used in place of the speaker 152 as in the case of the residential alarm 10-1.

  These details are basically the same as the wireless communication unit 20, the memory 22, the notification unit 26, the operation unit 28, and the battery power supply 30 provided in the residential alarm device 10-1 in FIG. 2 except for the sensor unit 124 that detects gas leakage. Will be the same.

  The processor 118 is provided with an event detection unit 158, a transmission processing unit 160, a reception processing unit 162, and an alarm processing unit 164 as functions realized by executing the program. The functions of the event detection unit 158, the transmission processing unit 160, the reception processing unit 162, and the alarm processing unit 164 are the event detection unit 58, the transmission processing unit 60, and the reception processing unit that are provided in the processor of the residential alarm device 10-1 in FIG. 62 and the alarm processing unit 64, the first abnormality detected by the event detection unit 158 is a gas leak, and the second abnormality due to the event signal received from the other residential alarm by the reception processing unit 160. It is different in that it becomes a fire alarm, but otherwise it is basically the same.

  The second abnormality alarm information 147 stored in the memory 122 is an alarm output when receiving an event signal indicating a fire alarm that is a different kind of abnormality with respect to gas leakage from the resident alarm 10-1 to 10-5. For example, voice data indicating, for example, “please confirm that another fire alarm has been activated” is stored as a voice message output from the speaker 152.

  FIG. 5 is a flowchart showing details of the fire monitoring process in the residential alarm device 10-1 in FIG. 2, which is a process by executing the program of the processor 18.

  In FIG. 5, the fire monitoring process monitors the fire alarm in step S1, and when the detection signal output from the sensor unit 24 exceeds a predetermined fire level, the fire alarm is determined and the process proceeds to step S2. The event signal including the serial number, the transmission source code, the group code indicating the group G1, the on / off code indicating the alarm on, and the event code indicating the fire shown in FIG. 3 is wirelessly transmitted to the other residential alarm and the gas leak alarm. After the transmission, an alarm indicating the interlocking source is output in step S3 (first abnormality alarm).

  Subsequently, in step S4, it is determined whether or not there is a fire recovery in which the detection signal from the sensor unit 24 is reduced and the fire alarm disappears. If the fire alarm continues, the alarm stop switch 56 determines in step S5. Whether or not there is an alarm stop operation is determined, and if there is no alarm stop operation, the process of determining whether or not an alarm stop event signal belonging to the same or linked group is received from another resident alarm is repeated in step S6. 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 S4 to S6, when the detection signal from the sensor unit 24 decreases and the fire alarm is lost, fire recovery is determined in step S4, and in step S4, a group indicating the serial number, transmission source code, and group G1 An event signal including a sign, an on / off code indicating an alarm off, and an event code indicating a fire is transmitted to the other housing and gas leak alarms, and the operation proceeds to step S9 to stop the interlocking source alarm, and the normal monitoring state Return to.

  In step S6, it is determined whether or not an event signal has been received indicating that the alarm has been stopped from another residential alarm. If the received event signal includes a group code indicating the same group G1 or a group code indicating the cooperation group G2, an on / off code indicating alarm off, and an event code indicating fire, an event indicating an alarm stop It is determined that the signal has been received, and the process proceeds to step S9 to stop the fire alarm as the interlocking source and return to the normal monitoring state.

  Not limited to this, the alarm stop process may depend on any of the patterns (1) to (3) described above. Further, the display by the LED 54 can be different from the acoustic alarm stop processing, such as performing history (memory) display as described above.

  Of course, an event signal indicating an alarm stop from the gas leak alarm may be received to stop the fire alarm. For example, the gas leak alarm devices 12-1 to 12-3 may be provided with a fire alarm stop switch, and when this is operated, an event signal indicating that the fire alarm is off can be transmitted. In addition, there is a method of stopping the fire alarm based on reception of an event signal for stopping the gas leak alarm.

  If it is determined in step S5 that its own alarm stop operation has been performed, the process proceeds to step S8, and the serial number, the transmission source code, the group code indicating group G1, and the ON / OFF code indicating alarm OFF are set to the other housing alarm and gas leak alarm. , And an event signal including an event code indicating a fire, and the fire alarm of the interlocking source is stopped in step S9.

  On the other hand, if it is not a fire alarm in step S1, it is determined in step S10 whether or not an event signal has been received from another house alarm or gas leak alarm, and if it is determined that an event signal has been received, the process proceeds to step S11. To determine whether the event code is the same type of fire event as the self.

  The event signal received at this time includes a group code indicating the same group G1 or a group code indicating the cooperation group G2, an on / off code indicating alarm off, and an event code indicating the type of abnormality. If the event code is fire, it is determined that it is the same type of fire event as the detection target of the event, and the process proceeds to step S12, where a fire alarm (first abnormality alarm) as a linkage destination is performed.

  On the other hand, if it is determined from the event code of the event signal received in step S11 that the gas leak event is different from the self detection target, the process proceeds to step S13 and the second abnormality alarm information 47 stored in the memory 22 is added. Based on this, a gas leak alarm (second abnormality alarm) is output as the interlocking destination.

  Next, in step S14, it is determined whether or not an event signal indicating an abnormal recovery from another residence alarm or gas leak alarm is received. If the event signal received at this time includes a source code belonging to the same group or a group code indicating the cooperation group G2, an on / off code indicating alarm off, and an event code indicating fire or gas leak, It is determined that an event signal indicating recovery is received, and the process proceeds to step S18 to stop the fire or gas leak alarm as the interlocking destination and return to the normal monitoring state.

  If no event signal indicating abnormality recovery is received in step S14, it is determined in step S15 whether or not an event signal indicating alarm stop from another residence alarm or gas leak alarm is received. If the event signal received at this time includes a source code belonging to the same group or a group code indicating the cooperation group G2, an ON / OFF code indicating alarm OFF, and an event code indicating fire or gas leak, It is determined that the event signal indicating stop is received, and the process proceeds to step S18 to stop the fire or gas leak alarm as the interlocking destination and return to the normal monitoring state. In this case as well, it is possible to appropriately select from the contents and combination patterns of the acoustic alarm stop process and the display alarm stop process.

  Note that the event signal to be discriminated in step S14 transmitted due to abnormality recovery is the same as the event signal to be discriminated in step S15 transmitted due to alarm stop, so the processes in steps S14 and S15 are combined into one. May be.

  If no event signal indicating an alarm stop is received in step S15, it is determined in step S16 whether or not an alarm stop operation has been performed by the alarm stop switch 16, and if an alarm stop operation is determined, the process proceeds to step S17 and other residences are performed. After transmitting an event signal including a serial number, a transmission source code, a group code, an event on / off code indicating an alarm off, and an event code indicating a fire or gas leak to the alarm device and the gas leak alarm device, in step S18, the interlock destination The alarm indicating is stopped. When an alarm stop switch is provided for each abnormality type, the event code added to the event signal corresponds to the operated switch.

  FIG. 6 is a flowchart showing details of the gas leak monitoring process in the gas leak alarm device 12-1 of FIG.

  In FIG. 6, the gas leakage monitoring process monitors the gas leakage in step S21. When the detection signal output from the sensor unit 124 exceeds a predetermined level, the gas leakage is determined and the process proceeds to step S22. An event signal including a serial number, a transmission source code, a group code indicating group G1, an on / off code indicating alarm on, and an event code indicating gas leakage is wirelessly transmitted to other gas leak alarms and residential alarms. After that, in step S23, a gas leak alarm indicating the interlocking source is output.

  Subsequently, in step S24, it is determined whether or not there is a gas leak recovery in which the detection signal from the sensor unit 24 decreases and the gas leak disappears. If the gas leak continues, an alarm by the alarm stop switch 156 in step S25. It is determined whether or not there is a stop operation. If there is no alarm stop operation, the process of determining whether or not an alarm stop event signal belonging to the same or a linked group is received from another residential alarm is repeated in step S26. In addition, while the gas leak is continuing, the transmission of the event signal indicating the gas leak is repeated every predetermined time.

  During the processing cycle of steps S24 to S26, when the detection signal from the sensor unit 124 decreases and gas leakage is eliminated, recovery of gas leakage is determined in step S24, and a group indicating a serial number, a transmission source code, and a group G1 is determined in step S427. An event signal including a sign, an on / off code indicating an alarm off, and an event code indicating a gas leak is transmitted to the other gas leak alarms and the residential alarm, and the process proceeds to step S29 to stop the gas leak alarm as the interlock source. Return to the normal monitoring state.

  In step S26, it is determined whether or not an event signal has been received from another gas leak alarm indicating the alarm stop. If the event signal received at this time includes a group code indicating the same group G1 or a group code indicating the cooperation group G2, an on / off code indicating alarm off, and an event code indicating gas leakage, an alarm stop is indicated. It is determined that the event signal has been received, and the process proceeds to step S29 to stop the gas leak alarm as the interlocking source and return to the normal monitoring state.

  When it is determined in step S25 that its own alarm stop operation has been performed, the process proceeds to step S28, where other gas leak alarms and house alarms are serially numbered, a transmission source code, a group code indicating group G1, and an on / off code indicating alarm off. , And an event signal including an event code indicating a gas leak is transmitted, and the interlocking source gas leak alarm is stopped in step S29.

  Not limited to this, the alarm stop process may depend on any of the patterns (1) to (3) described above. Further, the display by the LED 154 can be different from the acoustic alarm stop process, such as performing a history (memory) display as described above.

  On the other hand, if there is no gas leak in step S1, it is determined in step S30 whether or not an event signal has been received from another gas leak alarm or residence alarm, and if it is determined that an event signal has been received, the process proceeds to step S31. It is determined whether or not the event code is a gas leak event of the same type as its detection target.

  The event signal received at this time includes a source code belonging to the same group G1 or a group code indicating the cooperation group G2, an on / off code indicating alarm off, and an event code indicating the type of abnormality. If the event code is a gas leak, it is determined that the event is the same type of gas leak event as that of its own detection, and the process proceeds to step S32 to perform a gas leak alarm (first abnormality alarm) as a linkage destination.

  On the other hand, when it is determined from the event code of the event signal received in step S31 that a different type of fire event is detected, the process proceeds to step S33 and is based on the second abnormality alarm information 147 stored in the memory 22. To output a fire alarm (second abnormality alarm) as the link destination.

  Next, in step S34, it is determined whether or not an event signal indicating an abnormal recovery from another gas leak alarm or residence alarm is received. If the event signal received at this time includes a group code indicating the same group or a group code indicating the cooperation group G2, an on / off code indicating an alarm off, and an event code indicating a fire or gas leak, an error recovery is performed. The process proceeds to step S38, stops the fire or gas leak alarm as the interlocking destination, and returns to the normal monitoring state.

  If no event signal indicating abnormality recovery is received in step S34, it is determined in step S35 whether or not an event signal indicating alarm stop from another gas leak alarm or residence alarm is received. If the event signal received at this time includes a group code indicating the same group G1 or a group code indicating the cooperation group G2, an on / off code indicating alarm off, and an event code indicating fire or gas leak, It is determined that the event signal indicating the stop is received, and the process proceeds to step S38 to stop the fire or gas leak alarm as the interlocking destination and return to the normal monitoring state.

  Note that the event signal to be discriminated in step S34 transmitted due to abnormality recovery is the same as the event signal to be discriminated in step S35 transmitted due to alarm stop, so the processes in steps S34 and S35 are combined into one. May be.

  If no event signal indicating alarm stop is received in step S35, the presence or absence of an alarm stop operation by the alarm stop switch 56 is determined in step S36. After transmitting an event signal including a serial number, a transmission source code, a group code, an event on / off code indicating an alarm off, and an event code indicating a gas leak or a fire to the alarm device and the gas leak alarm device, an interlock destination in step S38 The alarm indicating is stopped. When an alarm stop switch is provided for each abnormality type, the event code added to the event signal corresponds to the operated switch.

  Note that the flowcharts in the above-described embodiments have described a schematic example of processing, and the order of processing is not limited thereto. Further, it is possible to provide a delay time between each process or between processes, insert another determination, or the like.

  Since the same type of alarm (first abnormality alarm) as the subject of detection and the different kind of abnormality alarm (second abnormality alarm) are performed independently, the first alarm and the second alarm are output simultaneously. In some cases, the alarm stop or recovery in such a case may be performed only for either the first alarm or the second alarm. In this case, that is, when an event signal indicating the first alarm stop is received during the output of the first and second alarms, for example, only the first alarm is stopped and the second abnormality alarm continues. The process is to output.

  On the other hand, when an event signal indicating the first abnormality alarm is received during the second abnormality alarm, the second abnormality alarm is stopped and the first abnormality alarm is output. I can do it. As a result, for example, in some cases, it is possible to give an appropriate alarm to the user according to the degree of danger associated with the occurrence of an abnormality, such as giving priority to a fire over an abnormal signal from a crime prevention alarm device.

  The second abnormality alarm is not limited to the meaning of the second type alarm. It is also possible to process a plurality of abnormal alarms that are different from the detection target. Of course, the second alarm may be given priority in some cases. These priorities may be set by the user with a switch or other appropriate means, or may be set and registered in advance by various means using software or hardware.

  Even when the priorities are not set in this way, variations regarding the acoustic alarm, the display alarm, the stop processing thereof, and the like can be selected in the same manner as in the above embodiment. Depending on the type of alarm, setting priorities may be extremely difficult. In such cases, experts should consider the installation environment and other conditions, but there is no problem even if the user sets them. Only the range may be set by the user freely, and the rest may be set by the expert by means that cannot be changed by the user. The user can set priorities within a configurable range, and can pre-determine what to do when an abnormality occurs.

  In addition, for example, even when the first abnormality alarm is preferentially sounded, a priority process combining the sound alarm and the display alarm can be performed, for example, the second abnormality alarm is displayed. The priority processing can be made different depending on the difference between the linkage source and the linkage destination.

  For example, when the fire alarm is given the highest priority for the entire system, when the fire occurs, both the interlocking source and the interlocking destination sound alarms for fire. If a gas leak is occurring at the same time, the gas leak alarm that is the source of this interlocking alarm is given only by displaying the gas leak alarm that is the first abnormality alarm, and the second abnormality alarm is heard by voice. Alarms can be made.

  The fire alarm (residential alarm) alerts the gas leak that becomes the second abnormality alarm with a display while sound-alarming the fire that becomes the first abnormality alarm for itself. And, for example, even if the first abnormality alarm is given priority, if there is only the second abnormality, this is alarmed in the same manner as the priority alarm, and when the first abnormality occurs during this alarm A priority alarm is given to the first abnormality.

  Through this process, the system as a whole gives detailed alerts, so that the user can be sure of any abnormalities that have occurred, and the priority (high risk) abnormality can be known. I can do it. Further, for example, by displaying the interlock source display on and the interlock destination display blinking, it is possible to know whether the alarming device being viewed is the interlock source or the interlock destination.

  In this way, the priority can be given to the alarm, the alarm output method can be different between the linkage source and the linkage destination, and the combination can also be combined so that the user can deal more appropriately when an abnormality occurs. It becomes possible.

  In addition, the above embodiment takes an alarm system that performs a linked alarm by configuring a plurality of groups in which a house alarm that detects and alarms a fire and a gas leak alarm that detects and alarms a gas leak are combined. However, the present invention can be similarly applied to an alarm system including a CO alarm device and various crime prevention alarm devices in addition to the gas leak alarm device.

  In the above embodiment, the gas leak alarm device arranged as a heterogeneous alarm device for the home alarm device is provided with a wireless communication unit that performs transmission and reception, and bidirectional communication is performed as an example. The heterogeneous alarm device may be a one-way communication provided with only a transmission function for detecting an abnormality and transmitting an event signal.

  Further, the above-described embodiment is applicable not only to residential use but also to various types of alarm devices such as buildings and offices.

  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.
