Description

The present invention relates to an alarm device that detects an abnormality such as a fire and issues an alarm, and relays and transmits a signal to another alarm device to output an alarm in conjunction with the alarm device.

  Conventionally, residential alarms (hereinafter referred to as “residential alarms”) that detect and detect abnormalities such as fires and gas leaks in homes have become widespread. There have been commercialized residential alarms that can be linked to each other, and can construct an interlocking alarm system that can alarm the abnormality information of one residential alarm with other alarms, and operate with battery power and communicate wirelessly.

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.

  In such a conventional wireless alarm device that performs an interlocking alarm, not only each room in the house, but also an alarm device installed in a remote location such as an outdoor garage or another building may be interlocked. In addition, the communication environment may be different from the initial installation due to redesign of the room after the installation of the home alarm. For this reason, even if it was confirmed at the beginning of installation that multiple mortgages can communicate with each other, there may be some munitions that cannot communicate during operation, and when a fire is detected, it will be linked. There is a problem that a resident alarm that cannot be alarmed is generated, and the reliability of interlocking monitoring is not sufficiently guaranteed.

  In order to solve this problem, the inventor of the present application has a function of relaying the received signal to another alarm when the signal indicating a fire is received from the interlocking source. According to the alarm device having such a relay function, the radio signal indicating a fire is relayed one after another by the alarm device constituting the interlocking group, and even if there is a resident alarm device installed at a remote location, it is reliably transmitted by relay transmission. A fire signal can be received and alarmed.

  However, when relaying signals with multiple housing alarms that make up the interlocking group, the housing alarms of the same group must be followed by the ones installed at remote locations such as corners or garages. Since it is not installed, it is not necessary to repeat any more, and unlimited relaying may adversely affect neighboring wireless systems that use the same frequency band. In addition, when the home alarm device that received the relay signal relays the relay signal again, unnecessary communication is repeated, such as being re-received by the home alarm device that has once relayed, and traffic There was a problem that became complicated. In addition, the increase in the number of relay transmissions (the number of stages) increases the power consumption related to reception processing and transmission processing, thereby affecting the battery life.

  In addition, in the case of a conventional wireless house alarm, when an event signal is transmitted and received between house alarms, the order of the event signal is changed depending on the state of the propagation path including the relay, etc. There is a potential for inconsistencies and reduced reliability.

  In addition, the transmission of the event signal from the home alarm is a multi-transmission transmission in which the same event signal is transmitted multiple times to ensure communication reliability. This process is performed a plurality of times, which increases the processing load.

The present invention aims at providing an alarm device that performs relay transmission in the appropriate range for controllable medium Tsugikai number (stage number) improves the reliability of the interlocking monitored by relay transmission.

In addition, the present invention provides a wireless disaster prevention system, a sensor node, a radio relay node, and a wireless disaster prevention node that do not cause a problem even if the reception order of event signals is changed and that reduce the burden due to reception processing of the same event signal.

  Here, the abnormality determination unit is included in the event detection unit.

The event processing unit transmits an event signal or relay event signal including a serial number and a transmission source ID that sequentially increase with each transmission,
When the relay control unit receives the event signal or the relay event signal from another alarm device, the relay control unit determines the set of the serial number and the transmission source ID included in the event signal or the relay event signal, and the already received serial number and the transmission source ID. If they match, the event signal or the relay of the relay event signal is terminated.

  When the relay control unit receives an event signal or a relay event signal from the interlocking source or the relay source alarm device, the relay control unit transmits the relay event signal at a timing different from that of the other alarm devices in the interlocking relationship.

  When the event processing unit receives an abnormality detection signal from the sensor unit and detects an event with an abnormality in the event detection unit, the event processing unit outputs an abnormality alarm indicating an interlocking source and sends an event signal indicating the abnormality to an interlocking alarm device On the other hand, when an event signal or relay event signal indicating abnormality is received from the interlocking source or relay source alarm device, an abnormality monitoring unit that outputs an abnormality alarm indicating the interlocking destination is provided.

(Serial number control)
The present invention is an alarm device that detects an abnormality and outputs an alarm indicating an interlocking source, and transmits an alarm signal indicating an interlocking destination by transmitting an event signal indicating an abnormality to another alarm device.
A serial number setting unit that repeatedly generates a serial number that continuously changes between a predetermined minimum value and a predetermined maximum value, and transmits the event signal by setting the generated serial number as the event signal. When,
The source code and serial number are acquired from the received event signal, and for each source code, the update prohibition range from the acquired serial number to the serial number before the predetermined number is set and maintained for a predetermined time, and the update is prohibited. A serial number management unit that prohibits processing of received event signals having serial numbers that fall within the range;
Is provided.

Here, the serial number setting unit repeatedly generates N consecutive numbers that continuously change between 0 and a predetermined maximum value (N−1), and uses the consecutive numbers generated during transmission as event signals. Set and send,
The serial number management unit acquires a serial number from the received event signal, and sets an update prohibition range up to a serial number that is N / 2 before the acquired serial number.

When the serial number management unit receives an event signal with a serial number that does not fall within the update prohibition range, the serial number management unit updates the update prohibition range to a new update prohibition range from the received serial number to a serial number that is a predetermined number before. Keep time.

(Relay control)
According to the present invention, an alarm device that has received an event signal from an alarm device that has detected an event such as an abnormality performs processing such as an alarm based on the event signal, and relays and transmits the received event signal, thereby There are residential alarms installed in places where radio waves do not reach or are difficult to reach due to the distance from the alarm that detected the alarm, or alarms whose communication environment has deteriorated due to room redesign, etc. Even so, it is possible to reliably receive an event signal through an event signal communication using an alarm device at a close distance as a relay source, and to issue a linked alarm such as an abnormality, thereby improving the reliability of the linked alarm by wireless communication. be able to.

  In addition, the event signal includes information for controlling the number of relays, so that the number of relays is appropriately controlled as necessary, preventing adverse effects on neighboring systems due to unnecessary relays, and power related to unnecessary relay processing Consumption can be reduced.

  In addition, by controlling the number of relays according to the type of event signal, for event signals indicating abnormalities such as highly urgent fires, it is possible to reliably signal the alarm devices in the interlocking group by increasing the number of relays. Transmits a linked alarm and, on the other hand, for less urgent problems, the number of relays is relatively reduced to reduce power consumption and enable optimal system linkage.

  Also, when the combination of the serial number and source code included in the event signal by the linkage source is the same as the event signal that has already been received and relayed, the relay is terminated and the relay of the same event signal is prevented from being repeated. To do.

  Also, it is expected that the same event signal will be received and relayed simultaneously by multiple alarm devices, but by relaying at different delay timings for each alarm device, the event signal collision probability due to relay transmission is lowered. It can be relayed reliably.

(Serial number control)
According to the present invention, a continuous number that continuously changes within a predetermined range is generated, and when the event signal is transmitted by multiple continuous transmission, the generated continuous number is set as an event signal and transmitted. When the update prohibition range up to the received serial number and the serial number received before that is set, and the serial number that falls within the update prohibition range is received at the next event signal reception, the reception order of the event signals is switched. Since the reception process is not performed because it is determined that the event signal has been received, it is possible to reliably prevent problems caused by switching the reception order of event signals, and to ensure the reliability of communication between alarm devices and the reliability of interlocking operations. Can be increased.

Also, when receiving multiple same event signals transmitted by multiple consecutive transmissions, the event signal with the same serial number received after that will be within the update prohibition range by setting the update prohibition range by receiving the first event signal. Processing for analyzing the reception event signal is not performed, and the processing load can be reduced.

  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 alarms 10-1 to 10-5 has a function of transmitting / receiving event signals to / from each other wirelessly and a function of relaying event signals by controlling the number of relays. A group of -1 to 10-5 constitutes a fire monitor for 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. When the resident guard 10-4 detects a fire, the resident guard 10-4 functions as an interlocking source, and fires the other resident guards 10-1 to 10-3, 10-5 that are interlocking destinations. The event signal shown is transmitted by radio. Of the other home alarm devices 10-1 to 10-3, 10-5, the home alarm device that has received an event signal indicating a fire from the home alarm device 10-4 as the interlocking source performs an alarm operation as the interlocking destination. The event signal received and received is relayed to another home alarm device by the control described later.

  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 the alarm sound output.

  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. In addition, the display by the LED of the linkage source and the linkage destination may be displayed in different colors using a two-color LED or the like.

  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 74, a relay count table 76, and a relay management table 78. In the group management table 74, the transmission source codes of the residential alarm devices 10-1 to 10-5 constituting the group are registered in advance. In the relay count table 76, a predetermined relay count is registered in advance according to the event type. The relay management table 78 stores information on event signals that have been relayed once.

In the present embodiment, the sensor unit 34 is provided with the smoke detector unit 16. Smoke detector section 16 is the sensor unit 34 when capture smoke and outputs a detection signal. Detection signal is taken into CPU 28 (AD conversion), the fire determined exceeds a predetermined fire level CPU 28 side, also, that the detection signal is no longer fire by below fire level decreases (Fire Recovery).

  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 a normal monitoring state where no alarm is in effect, and when the inspection switch is operated at times other than during alarming, a warning voice message or the like is output from the notification unit 36.

  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 control 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. recovery, and a state change of the fault recovery etc. failure is eliminated in the battery power supply 40 or the sensor unit 34 upon detection of the event, after the event processor as linkage source, the linkage destination an event signal indicating a detection event 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 handling 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.

Abnormality monitoring unit 64 based on the detection signal of the sensor unit 3 4 or found when determining the fire, to confirm alarm sound such as "Woo Woo fire alarm indicating the interlocking source from the speaker 58 of the alert section 36 was activated ”Repeatedly output, drive the LED 22, and send an event signal indicating a fire alarm from the antenna 31 via the transmission circuit 42 of the wireless circuit unit 30 via the communication control unit (not shown) of the event processing unit 60. It is made to transmit toward the house police 10-2 to 10-5.

  In addition, when the abnormality monitoring unit 64 receives an event signal indicating a fire from any of the other home 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 the interlocking source itself. Continually outputs an alarm sound indicating the link destination, for example, a voice message “Please confirm that another fire alarm has been activated” 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 display an 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 restoration unit 68 stops the interlocking source alarm and returns it to the normal state when the smoke is no longer detected from the smoke detection unit 16 provided in the sensor unit 34, and an event signal indicating the restoration of the fire is generated. When the transmission circuit 42 of the radio circuit unit 30 transmits to the interlocking dwelling devices 10-2 to 10-5 via the communication control unit (not shown), an event signal indicating a fire reset from either the home alarm 10-2～10-5 when received by the receiving circuit 44 of the wireless circuit section 30, return to the normal state the interlocking destination alarm is stopped.

This allows the interlocking source alarm with home alarm 10-1 is issued, then when a fire condition is eliminated, the detection signal from the sensor unit 34 falls below the fire level, automatically engage the restoration unit 68 The original alarm sound 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 function of the relay control unit 62 is divided into a transmission relay control unit 70 and a reception relay control unit 72. The transmission relay control unit 70 sets the number of relays to the event signal transmitted to the interlocking alarm device when the event signal is received. The transmission process is performed by a communication control unit (not shown). Of course, the transmission relay control unit 70 may perform the transmission process.

Further, the reception relay control unit 72 controls the presence / absence of relay based on the number of relays included in the event signal when the event signal is received from another alarm device. There are a down-count method and an up-count method for controlling the number of relays in this embodiment.

  The transmission relay control unit 70 functions when an event signal is transmitted as an interlocking source when it detects the occurrence of an event (therefore, the transmission relay control unit 70 of this embodiment does not perform “relay” control). The reception relay control unit 72 functions when receiving and relaying an event signal from another alarm device.

In the down-count method, the transmission relay control unit 70 transmits a generated event including the relay number N set in advance in the relay number table 76, while the reception relay control unit 72 receives an event signal from another alarm device. When the value obtained by subtracting 1 from the number N of relays included in the event signal is 1 or more, relay transmission is performed.

  In the up-count method, the transmission relay control unit 70 registers a predetermined number N of relays in the relay number table 76 in advance and initializes the number of relays to zero for an occurrence event, while the reception relay control unit 72 When an event signal is received from another alarm device, if the value obtained by adding 1 to the number of relays included in the event signal is less than the number of registered relays, the event signal including the number of relays after addition is relayed and added. If the obtained value matches the registered relay count (or more), the relay is terminated.

Further, the event processing unit 60 transmits an event signal including a serial number (hereinafter referred to as “serial number”) that sequentially increases with each transmission and a transmission source code. control unit 72, upon receiving an event signal from the linkage source or relay source alarm device, a set of source code and serial number included in the event signal, already stored in the relay management table 78 of the memory 46 Compared with the set of received serial number and source code, if they match, the same event signal has already been relayed, so the relay of the event signal is terminated and the same event signal is not relayed repeatedly . This process will be described in detail later.

  Further, the reception relay control unit 72 relays and transmits an event signal at a different delay timing for each mortgage that constitutes the interlocking group registered in the relay management table 78 in advance. 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 relaying event signals can be made different from each other, and collision of event signals due to simultaneous relaying of a plurality of residence guards can be avoided.

  In FIG. 3, the relay control unit 62 is described as being divided into the transmission relay control unit 70 and the reception relay control unit 72. However, the same applies to only the relay control unit 62 having both functions. It is.

  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, a relay count 55, 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.

  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.

  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 relay count 55 is information for controlling the relay count of the event signal. In the case of the down count method, the relay count corresponding to the event type acquired from the relay count table 76 by the interlocking home resident is initialized. Further, in the up-count method, the number of relays at which the interlocking home resident alarm becomes zero is initialized.

  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 74 stored in the memory 46 of FIG. 3, and the 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.

  The registration process of the group management table 74 is, for example, when performing factory registration or when 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 alarm 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 device, and the transmission source code included in the registered event signal is acquired and registered in the group management table 74 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. 5 (B) is an explanatory view showing the content of the relay count table 76 stored in the memory 46 of FIG. 3, as the event type, fire, fire reset, alarm stop, it must be divided into disorders and Disaster Recovery Is registered in advance. Relay number of fire, fire restoration, set a lot, for example three times for urgent events, such as alarm stop, is set at least once, for example, for low-good venting of urgency, such as failure or disaster recovery.

  FIG. 5C is an explanatory diagram showing the contents of the relay management table 78 stored in the memory 46 of FIG. 3. For example, the event signal is received from the mortgage alarm device 10-2 having the transmission source code = 102 and relayed. The stored contents are shown.

  For example, assuming that an event signal is received from the home guard 10-2 without being registered in the relay management table 78, a set of serial number = 00001 and source code = 102 is acquired from the received event signal. Since there is no same set in the relay management table 78, the event signal is relayed and registered, and a set of serial number = 00001 and source code = 102 is registered in the relay management table 78.

  After that, when the same relayed event signal is received again through relaying by another home guard, 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 78. 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 the present embodiment, the transmission source code must be added at the time of signal transmission. Therefore, in addition to the transmission source code 52, the relay transmission source code is actually included in the event signal 48. Will be included. Therefore, 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 transmission source code of the interlocking source. In the following description, the relay transmission source code is omitted.

  Furthermore, a different delay timing is registered in advance in the relay management table 78 for each residential alarm 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.

That is, the reception relay control unit 72 of the relay control unit 62 shown in FIG. 3, linkage source or upon receiving an event signal from the relay source alarm device, an event signal at the other alarm devices and different timings in conjunction relationship Is relayed. For example, the reception relay control unit 72 relays and transmits an event signal at a delay timing based on its own transmission source code when receiving the event signal from the interlocking source or relay source alarm device.

  For example, the resident guard 10-1 that has registered the relay management table 78 in FIG. 5C has the transmission source code = 101, so that “1” at the end of the transmission source code = 101 is used as the delay timing. Registered. 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. 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, taking as an example the case where the number of relays is controlled by the down-count method, and the process by the execution of the program of the CPU 28 of FIG. It becomes.

In FIG. 7, the fire monitoring process monitors the fire in step S11. When the detection signal output from the sensor unit 34 exceeds a predetermined fire level, the fire is determined and the process proceeds to step S12 to perform transmission relay control. Do. Since this is the link source, the transmission relay control here is the first transmission that does not include the meaning of relay .

  FIG. 8 is a flowchart showing details of the transmission relay control in step S12 in FIG. 7. Since this is a down-count method, it is a generated event with reference to the relay count table 76 in FIG. 5B in step S41. The relay count N = 3 corresponding to the fire is acquired, the relay count N = 3 is set in the event signal in step S42, and the process returns to FIG.

  Subsequently, in step S13, an event signal including a serial number, a transmission source code, the number of relays = 3, and an event code indicating a fire is wirelessly transmitted to another residential alarm device. In step S14, an alarm indicating the interlocking source is output.

  Subsequently, in step S15, it is determined whether or not there is a fire recovery in which the detection signal of the sensor unit 34 is reduced and the fire disappears. If the fire continues, the presence or absence of an alarm stop operation by the alarm stop switch 20 is determined in step S16. 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 S17. In addition, while the fire is continuing, the transmission of the event signal indicating the fire alert is repeated every predetermined time.

  During the processing cycle of steps S15 to S17, when the detection signal from the sensor unit 34 decreases and the fire disappears, fire recovery is determined in step S15, and the event is generated by the transmission relay control shown in FIG. 8 in step S19. After setting the number of relays corresponding to fire recovery = 3 as an event signal, in step S20, an event signal including a serial number, a transmission source code, the number of relays = 3, and an event code indicating a fire recovery is transmitted to the other residence police. In step S23, the interlocking source alarm is stopped. In this case, the normal monitoring state is restored. The transmission in step S20 is the first transmission as the interlocking source.

  If it is determined in step S17 that an alarm stop event signal has been received from another residential alarm device, reception relay control is performed in step S18, and then the process proceeds to step S23 to stop the interlocking source alarm. The transmission in step S18 is relay transmission as a linkage destination. Here, details of the reception relay control in step 18 are as shown in the flowchart of FIG.

  The reception relay control in FIG. 9 is a down-count method, and a combination of a serial number and a transmission source code is acquired from the event signal received in step S51, and whether or not it matches the group registered in the relay management table 78 in step S52. If they do not coincide with each other, the process proceeds to step S53, where a set of serial number and source code is registered in the relay management table 78, and then the number N of relays is acquired from the event signal in step S54.

In step S55, the number of relays is subtracted from N = N-1.
In step S56, it is determined whether the number of relays has reached N = 0. If the number N of relays has not reached zero, it is in the middle of relaying and the process proceeds to step S57, where the number N of relays calculated as N = N−1 is set as an event signal, and the serial number, source code, An event signal including an event code indicating the number of relay times and alarm stop is prepared.

  Subsequently, at step S58, the arrival at the delay timing acquired from the relay management table 78 of FIG. 5C is monitored. When the arrival at the delay timing is determined, the process proceeds to step S59, where the serial number, source code, An event signal including an event code indicating the number of times of relaying and alarm stop is relayed.

If the set matches the group registered in the relay management table 78 in step S52, the process proceeds to step S60 to end the relay. The pair registered in the relay management table 78 is updated by overwriting the pair of the serial number and the transmission source code acquired from the next received event signal. In addition, without the override, it is also possible to store a certain number of sets in a first in, first out.

  If an event signal is transmitted as a linkage source, it will not be relayed again when the event relayed from the linkage destination is received. For example, when an event signal is sent as the linkage source, its own relay management The table can store its own transmission source code and serial number.

Further the relay number N in step S56 even if it reaches the N = 0, and terminates the relay proceeds to step S 60.

  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.

  Referring to FIG. 7 again, if it is determined in step S16 that the own alarm stop operation has been performed, the process proceeds to step S21, and the number of relays corresponding to the alarm stop which is an event generated by the transmission relay control shown in FIG. After setting the event signal, in step S22, an event signal including a serial number, a transmission source code, the number of relays = 3, and an event code indicating an alarm stop is transmitted to the other home alarm devices, and the interlock source alarm is stopped in step S23. To do. The transmission in step S21 is the first transmission as a link source.

  On the other hand, if it is not a fire alarm in step S11, it is determined in step S24 whether or not an event signal indicating a fire from another residential alarm is received.

  If it is determined that an event signal indicating a fire is received from another house alarm, the process proceeds to step S25 to perform the condition determination by performing the reception relay control shown in FIG. After relaying and transmitting an event signal including an event code indicating the number, transmission source code, number of relays, and fire, the process proceeds to step S26 to output an alarm indicating the interlocking destination. The transmission in step S25 is relay transmission as a link destination.

  Subsequently, in step S27, it is determined whether or not an event signal indicating a fire recovery from another home police is received, and when an event signal indicating a fire recovery is received, the process proceeds to step S32 and the reception relay control shown in FIG. After performing relay transmission of an event signal including an event code indicating a serial number, a transmission source code, the number of relays, and a fire recovery to other dwelling devices as necessary, the process proceeds to step S33 and a linkage destination alarm is generated. In this case, the normal monitoring state is restored.

  If no event signal indicating a fire recovery is received in step S27, it is checked in step S28 whether an event signal indicating an alarm stop from another resident alarm is received, and an event signal indicating an alarm stop is received. , The process proceeds to step S32 to perform the reception relay control shown in FIG. 9 and relay transmission of an event signal including an event code indicating a serial number, a transmission source code, the number of relays, and an alarm stop to other dwelling devices. After that, the alarm indicating the interlock destination is stopped in step S33.

  If no event signal indicating an alarm stop is received in step S28, it is determined in step S29 whether or not an alarm stop operation has been performed by the alarm stop switch 20, and if an alarm stop operation is determined, the process proceeds to step S30 and proceeds to FIG. The number of relays corresponding to the alarm stop which is the generated event is set to the event signal by the transmission relay control shown, and the serial number, the transmission source code, the number of relays, and the alarm stop are indicated to the other mortgages in step S31. After relaying the event signal including the event code, the alarm indicating the linkage destination is stopped in step S32. The transmission at step S30 is the initial transmission as the interlocking source.

  FIG. 10 is a flowchart showing details of the failure monitoring process including relay control in step S3 of FIG.

  Failure types include battery voltage drop (low battery failure), sensor failure (sensor failure), etc. When a low battery failure occurs, the failure event signal is sent as the linkage source, or the failure event is the linkage destination. Battery relaying can be suppressed by not performing signal relay control.

  The failure monitoring process in FIG. 10 will be described as follows by taking the sensor failure of the sensor unit 34 as an example.

  In FIG. 10, the presence or absence of detection of a sensor failure in the sensor unit 34 is monitored in step S61, and the detection signal from the sensor unit 34 is a predetermined zero point level (normal signal level at normal time: the detection capability of the sensor is lost). In order to check if 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 S62 and the transmission relay control shown in FIG. After setting the number of relays corresponding to a certain fault detection = 1 to the event signal, in step S63, an event signal including a serial number, a transmission source code, the number of relays = 1, and an event code indicating a sensor fault is sent to another resident alarm. Transmit by radio. Subsequently, in step S64, a failure alarm indicating the interlocking source is output.

  Subsequently, in step S65, 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 S66. 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 S67. 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 from the sensor unit 34 recovers to the zero point level during the processing cycle of steps S65 to S67, failure recovery is determined in step S65, and the process proceeds to step S69, where the failure is an event that has occurred by the transmission relay control shown in FIG. After setting the number of relays corresponding to recovery = 1 to the event signal, and transmitting the event signal including the serial number, the transmission source code, the number of relays = 1, and the event code indicating the failure recovery to the other residence police in step S70 In step S73, the interlocking source alarm is stopped, and in this case, the normal monitoring state is restored. The transmission in step S70 is the initial transmission as the link source.

  If it is determined in step S67 that an alarm stop event signal has been received from another house alarm device, the process proceeds to step S68 to perform the reception relay control shown in FIG. 9, and the other house alarm device has a serial number, a transmission source code, After relaying an event signal including an event code indicating the number of times of relaying and alarm stop, the process proceeds to step S73 to stop the interlocking source alarm. The transmission in step S68 is relay transmission as a link destination. Further, when it is determined in step S66 that the own alarm stop operation has been performed, the process proceeds to step S71, and after setting the number of relays corresponding to the alarm stop as an occurrence event by the transmission relay control shown in FIG. In step S72, an event signal including an event code indicating a serial number, a transmission source code, the number of relays = 3, and an alarm stop is relay-transmitted to the other home alarm devices, and the interlocking source alarm is stopped in step S73.

  On the other hand, if a sensor failure is not detected in step S61, it is determined in step S74 whether or not an event signal indicating the failure has been received from another house alarm device. If it is determined that an event signal indicating a sensor failure has been received from another house alarm, the process proceeds to step S75, and the reception relay control shown in FIG. 9 is performed to give another house alarm a serial number, a transmission source code, and the number of relays. Then, after relaying the event signal including the event code indicating the alarm stop, the process proceeds to step S76, and a failure alarm indicating the interlock destination is output. The transmission in step S75 is relay transmission as a link destination. When the number of relays = 1, the relay is terminated.

  Subsequently, in step S77, it is determined whether or not an event signal indicating failure recovery from another resident alarm is received. When an event signal indicating failure recovery is received, the process proceeds to step S82 and the reception relay shown in FIG. After controlling and relaying the event signal including the event code indicating the serial number, source code, number of relays, and fault recovery to the other mortgages, the process proceeds to step S83 to stop the fault alarm indicating the interlock destination In this case, the normal monitoring state is restored. The transmission in step S82 is relay transmission as a linkage destination. When the number of relays = 1, the relay is terminated.

  If no failure recovery event signal has been received in step S77, it is checked in step S78 whether or not an event signal has been received indicating that an alarm has been stopped from another house alarm device, and it has been determined that an event signal has been received indicating that the alarm has stopped. After proceeding to step S82 and performing the reception relay control shown in FIG. 9 and relaying the event signal including the event code indicating the serial number, the transmission source code, the number of relays, and the alarm stop to the other home alarm devices ( When the number of times of relay is 3, the relay ends), and the alarm indicating the interlock destination is stopped in step S83.

  If no alarm stop event signal is received in step S78, the presence or absence of an alarm stop operation by the alarm stop switch 20 is determined in step S79. If the alarm stop operation is determined, the process proceeds to step S80 and the transmission shown in FIG. Relay number = 3 corresponding to alarm stop, which is an event generated by relay control, is set as an event signal. In step S81, an event signal including a serial number, a transmission source code, relay number = 3, and an event code indicating alarm stop is set. After transmitting to the home alarm device, the alarm indicating the link destination is stopped in step S83. The transmission in step S81 is the first transmission as a link source.

  Although FIG. 10 shows a sensor failure as an example, the same may be applied to a low battery failure detected when the power supply voltage from the battery power supply 40 drops below a predetermined voltage.

  FIG. 11 and FIG. 12 are flowcharts showing transmission relay control and reception relay control according to the present invention using the up-count method.

  Since the transmission relay control in FIG. 11 is an up-count method, in step S101, N = 0 is set as the number N of event signal relays, and the process returns to the main routine in FIG.

In the reception relay control of FIG. 12, a set of serial number and transmission source code is acquired from the event signal received in step S111, and it is determined whether or not the set matches the group registered in the relay management table 78 in step S112. and, in the case of disagreement after registering a set of serial number and transmission source code to the relay management table 78 proceeds to step S113, obtains the number of relays N from the event signal in step S114.

In step S115, N = N + 1 is added to the number of relays.
In step S116, the relay count corresponding to the event type is acquired as the threshold count Nth from the relay count table 76, and the flow advances to step S117 to compare the relay count N obtained by the addition in step S115 with the threshold count Nth. If so, proceed to step S118, set the number N of relays calculated as N = N + 1 to the event signal, and prepare an event signal including the serial number, source code, number of relays, and event code To do.

  Subsequently, at step S119, the arrival at the delay timing acquired from the relay management table 78 of FIG. 5C is monitored, and when the arrival at the delay timing is determined, the process proceeds to step S120, where the serial number, source code, An event signal including the number of relays and the event code is relayed and transmitted.

If the set matches the group registered in the relay management table 78 in step S112, the process proceeds to step S121 to end the relay. The pair registered in the relay management table 78 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 relayed again when the event transmitted from the linkage destination is relayed. For example, when an event signal is sent as a linkage source, its own relay management table It is possible to store the source code and the serial number of the own.

  Further, when the number N of relays reaches the threshold number Nth in step S117, the process proceeds to step S121 to end the relay.

  Up to now, the relay count N as the relay count information has been described as 0, 1, 2, 3,..., But the increment / decrement pitch does not necessarily have to be in increments of “1”, and is not necessarily “0”. There is no need to end the relay. In short, the relay is terminated at a predetermined value, increment / decrement is performed according to a predetermined agreement, and the number of relays as the number information does not need to be set to “1”, for example. It is only necessary to specify the number of times of actual recognition processing according to a predetermined agreement from the received number of times information.

  FIG. 13 is a block diagram showing another embodiment of the house alarm according to the present invention for performing serial number processing. FIG. 13 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. The battery power supply 40 to supply is provided, and this point is the same as the embodiment of FIG.

  The CPU 28 is provided with an event processing unit 60 as a function realized by executing the program. In this embodiment, the relay control unit is omitted.

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. recovery, and a state change of the fault recovery etc. failure is eliminated in the battery power supply 40 or the sensor unit 34 upon detection of the event, after the event processor as linkage source, the linkage destination an event signal indicating a detection event 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 handling process as the interlocking destination is performed.

  In order to realize this function, the event processing unit 60 is provided with 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. This is the same as the embodiment of FIG.

  In the present embodiment, the CPU 28 is further provided with a serial number setting unit 80 and a serial number management unit 82. Correspondingly, the serial number management information 84 generated when the event signal is received is stored in the memory 46. Has been.

  Here, the event signal transmission by the transmission circuit 42 of the radio circuit unit 30 is, for example, the first transmission in which T1 second transmission and T1 second pause of a plurality of event signal data are repeated three times, and are randomly assigned to each alarm device. After a lapse of a vacant time T2 in the range of 3 to 8 seconds, the second transmission that repeats the same transmission is performed again, and this is set as one set of event signal transmission.

  The serial number setting unit 80 repeatedly generates, for example, a serial number that continuously changes between 000 and 255 (hereinafter simply referred to as “serial number”), and the serial number generated at the transmission timing of the event signal. Set to event signal and send by multiple continuous transmission. The serial number changing in the range of 000 to 255 is generated by, for example, clock counting of an 8-bit counter.

  The serial number management unit 82 generates the serial number management information 84 based on the serial number corresponding to the transmission source code included in the event signal and receives the serial number management when receiving the event signal from another resident guard. Run. In the serial number management information 84, an update prohibition range including, for example, 128 serial numbers that are half of the serial number generation range from the acquired serial number to the serial number that is a predetermined number before is set.

Further, when generating the serial number management information 84 that includes the updated prohibited range in ascending order management section 82, and start the sequence number management timer for managing a lifetime of serial number management information 84. The serial number management timer is set to 30 seconds, for example. The set time of the serial number management timer is set to a time within a time until retry transmission from another home alarm and within a time until a counter for generating a serial number counts 128.

  When the update prohibition range is set in the generation of the serial number management information 84, an event signal reception processing prohibition state in which processing is not performed even if a serial event signal that falls within the update prohibition range is received thereafter. Become. For this reason, even if the same event signal is received by multiple consecutive transmissions from other home alarm devices, the subsequent processing is performed because the serial number obtained from the received event signal is within the update prohibited range at that time In other words, it is possible to avoid two or more overlapping processes for the same event signal.

  Even if the event signal reception order is changed, the sequence number of the previous event signal is not processed by entering the update prohibition range set at that time, and the event signal order is changed and received. Can prevent problems.

  On the other hand, before receiving the serial number management timer, if a serial number event signal that does not fall within the update prohibition range set at that time is received, processing corresponding to the event signal content is executed, The update prohibition range of the serial number management information 84 is set again based on the newly received serial number, and update processing is executed to reset and start the serial number management timer.

  If the serial number management timer expires without receiving the next event signal, the generated serial number management information 84 is deleted.

  FIG. 14 is an explanatory diagram showing an update prohibition range set by the serial number management unit 82 provided in the residential alarm 10-1 of FIG.

  First, the serial number setting unit 80 that sets a serial number at the time of transmitting an event signal changes the serial number in the range of 0 to 255 by the counting operation of the 8-bit counter, and the change in the serial number is shown in FIG. As shown in Fig. 5, it can be expressed as a sequential circle that continuously changes from 0 to 255.

  In the present embodiment for serial number circles, the range of 128 serial numbers that are half of the received serial number X and the circle preceding it is set as the update prohibition range 86, and the range beyond that Is set in the updatable area 88.

FIG. 14A shows a case where a serial number X smaller than the median of the serial number circle is received, and the update prohibition range 86 in this case is as follows. Here, Y is a sign of the update prohibition range 86.
0 ≦ Y ≦ X and (129 + X) ≦ Y ≦ 255
For example, if the serial number X = 030, the update prohibition range Y = 030-000, 255-129.

FIG. 14B shows a case where a serial number X larger than the median value of the serial number circle is received, and the update prohibition range 86 in this case is as follows.
(X-127) ≦ Y ≦ X
For example, if the serial number X = 225, the update prohibition range Y = 225-098.

  FIG. 15 shows a list of conditional expressions for setting the update prohibition range 86 in the serial number circle shown in FIG. These conditional expressions may be the two conditional expressions shown in FIGS.

  FIG. 16A is an explanatory diagram showing the contents of serial number management information (serial number management record) 84 generated and managed by the serial number management unit 82 provided in the residence guard 10-1 of FIG. In FIG. 16A, serial number management information 84 includes a transmission source code 90, a serial number 92, an update prohibition range 94, and a serial number management timer 96.

  The transmission source code 90 and the serial number 92 are acquired from the received event signal. The value of the update prohibition range 94 is calculated from the value X of the serial number 92 acquired based on the conditional expression of FIG. The serial number management timer 96 is, for example, a 30-second timer that is started when the serial number management information 84 is generated, and holds the serial number management information 84 as valid information until the time is up to 30 seconds. It is a kind of life timer that erases the serial number management information 84 when it is up.

FIGS. 16B to 16D are specific examples of the serial number management information 84 generated when the serial number X = 000,030,225 is obtained by receiving the event signal. The initial value at the time of generation is 30 seconds, and when the time reaches 0 seconds, the time-up occurs and the serial number management information 84 is deleted.

  FIG. 17 is a flowchart showing the fire monitoring process in the house alarm including the serial number process of FIG. 13, and is a process by executing the program of the CPU 28 of FIG.

  In FIG. 17, the fire monitoring process monitors the fire in step S131. If the detection signal output from the sensor unit 34 exceeds a predetermined fire level, the fire is determined and the process proceeds to step S132, where the serial number setting process is performed. I do.

  The serial number setting process in step S132 acquires the serial number currently generated by the counter that repeatedly performs the counting operation in the range of 000 to 255, sets the acquired serial number in the event signal, and in step S133 While transmitting the event signal which shows a fire to another residence alarm device, the alarm as a link origin is output by step S134.

  Subsequently, in step S135, it is determined whether or not there is a fire recovery in which the detection signal of the sensor unit 34 is reduced and the fire disappears (fire detection state is canceled). If the fire continues, an alarm stop switch in step S136. Whether or not there is an alarm stop operation by 20 is determined, and 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 S137. 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 S135 to S137, when the detection signal from the sensor unit 34 decreases and the fire disappears, fire recovery is determined in step S135, and the currently generated serial number is acquired from the counter in step S138. In step S139, an event signal including an event code indicating a fire recovery is transmitted to the other residential alarm, and the process proceeds to step S145 to stop the interlocking source alarm. In this case, the normal monitoring state is set. Return.

  If it is determined in step S137 that an alarm stop event signal has been received from another residential alarm, the serial number management process shown in steps S140 to 142 is executed. In this serial number management process, the transmission source code and serial number obtained from the event signal in step S140 are notified to the serial number management unit 82, and it is determined whether or not an update prohibition range is set in step S141. If it is determined that the update prohibition range is not set, the process proceeds to step 145, and the interlocking source alarm is stopped based on the received alarm event signal.

  On the other hand, if it is determined in step S141 that the update prohibition range is set, the process proceeds to step S142, where it is determined whether the received serial number is within the update prohibition range, and if the determination is within the range, the alarm received in step S145 is received. It skips without performing the process by the stop event signal. If it is determined in step S142 that it is not in the update prohibition range, the process proceeds to step S145, and the interlocking source alarm is stopped based on the received alarm event signal.

  If it is determined in step S136 that its own alarm stop operation has been performed, the process proceeds to step S143, where the serial number generated at the present time is set as an event signal. Then, an event signal including an event code indicating an alarm stop is transmitted, and the linkage source alarm is stopped in step S145.

  On the other hand, if it is not a fire in step S131, it is determined in step S146 whether or not an event signal indicating a fire from another house alarm is received.

  If it is determined that an event signal indicating a fire has been received from another house alarm, the process proceeds to step S147, and serial number management processing is executed based on the transmission source code and the serial number obtained from the received event signal. This serial number management process is the same as steps S140 to S142, and if the received serial number is within the update prohibition range, the linked destination alarm in step S148 based on the received fire event signal is not output as in route b. Skip processing. If the update prohibition range is not set or the serial number is not included in the update prohibition range, the process proceeds to step S148 as in route a, and the interlocking destination alarm is output based on the received fire event signal.

  Subsequently, in step S149, it is determined whether or not an event signal indicating a fire recovery from another home police is received, and when an event signal indicating a fire recovery is received, the process proceeds to step S154 and is the same as shown in steps S140 to S142. Execute serial number management processing. That is, if the received serial number is within the update prohibition range, the processing is skipped without stopping the interlocking destination alarm based on the received recovery event signal as in the route b. If the update prohibition range is not set or the serial number is not within the update prohibition range, the process proceeds to step S155 as in route a, and the interlocking destination alarm is stopped based on the received recovery event signal.

  If no event signal indicating a fire recovery is received in step S149, it is checked in step S150 whether an event signal indicating an alarm stop from another resident alarm is received, and an event signal indicating an alarm stop is received. Is determined, the process proceeds to step S154, and the same serial number management process as shown in steps S140 to S142 is executed. That is, if the received serial number is within the update prohibition range, the processing is skipped without stopping the interlocking destination alarm based on the received recovery event signal as in the route b. If the update prohibition range is not set or the serial number is not included in the update prohibition range, the process proceeds to step S155 as in route a, and the interlocking destination alarm is stopped based on the received alarm stop event signal. .

  If no event signal indicating an alarm stop is received in step S150, it is determined in step S151 whether or not an alarm stop operation is performed by the alarm stop switch 20, and if an alarm stop operation is determined, the process proceeds to step S152 and is generated at the present time. The serial number is set as an event signal, and an event signal including an event code indicating the serial number, the transmission source code, and the alarm stop is transmitted to the other residential alarm devices in step S153, and then the interlock destination is selected in step S155. Stop showing alarm.

  Here, the fire monitoring process of FIG. 17 differs from the fire monitoring process of FIG. 7 in that relay control is not performed, but the fire monitoring process with relay control of FIG. 7 is also the event in steps S13, S20, S22, and S31. Prior to signal transmission, serial number setting processing for acquiring the current serial number generated by the counter and setting it as an event signal is performed, and after receiving the event signal in steps S17, S24, S27, and S28, serial number setting processing is performed. Number management processing may be performed.

  This is the same for the fault monitoring process of FIG. 10 accompanied by the relay control shown in FIG. 10, and before the transmission of the event signal in steps S63, S70, S72, and S81, the current sequence generated by the counter is used. The serial number setting process for acquiring the serial number and setting it to the event signal is performed, and the serial number management process may be executed after receiving the event signals of steps S67, S74, S77, and S78.

  FIG. 18 is a flowchart showing the processing operation by the serial number management unit 82 provided in the residential alarm 10-1 of FIG. In FIG. 18, the serial number management process determines whether or not the transmission source code for receiving the event signal and the serial number have been acquired in step S161, and acquisition of the transmission source code and the serial number accompanying the reception of the event signal in FIG. Is determined, it is determined whether or not serial number management information has already been generated corresponding to the transmission source code acquired in step S162.

  If it is determined in step S162 that serial number management information has not been generated, the process advances to step S163 to set an update prohibition range from the serial number of the received event signal according to the conditional expression of FIG. The serial number management information 84 shown in FIG. 16 started by setting the management timer is generated.

  On the other hand, if it is determined in step S162 that the serial number management information has been generated, the process proceeds to step S164, where the serial number management information is updated. For updating the serial number management information, the serial number of the received event signal is rewritten to the value of the update prohibition range calculated according to the conditional expression of FIG. 15, and the serial number management timer is reset and started.

  Subsequently, in step S165, it is determined whether or not the serial number management timer of the serial number management information currently generated and managed has timed up. If the timed serial number management timer has been determined, the process proceeds to step S166, where serial number management is performed. Delete the serial number management information whose timer has expired.
