By the way, in conventional linked alarm systems, if a garage is built on the premises of a house, a fire alarm is installed in the garage and forms a linked group with the fire alarm in the house. You can also monitor fires in your garage.

However, since fire alarms are designed to be installed indoors, they do not have a waterproof structure and cannot monitor fires in vehicles parked in empty spaces on premises or in covered parking spaces that are exposed to rainwater.

For this reason, it is possible to monitor fires in parked vehicles by installing fire alarms on vehicles parked outdoors and forming a linked group with fire alarms installed inside houses. Can be done.

However, when a fire alarm is installed in a vehicle, the communication distance of the fire alarm that forms an interlocking group that operates as a power-saving wireless station of 1 mW or less is 100 meters or less, and when the vehicle leaves the parking place, Communication with other fire alarms installed in the house becomes impossible, and a linked group is no longer formed, resulting in a system failure.

For example, fire alarms in linked alarm systems undergo communication tests on a regular basis, and if communication with the fire alarm installed in a vehicle is cut off, a communication error will occur and the communication error will continue until the vehicle returns. There is a problem that system failures cannot be resolved.

An object of the present invention is to provide an alarm system and a vehicle-mounted monitoring means that can appropriately monitor abnormalities such as fire by including a house and vehicles parked on the premises in an interlocking group without causing system failure. shall be.

(basic effect)
The present invention provides an alarm system in which a plurality of monitoring means installed in a predetermined monitoring area including a building form an interlocking group to monitor and issue an alarm for a predetermined abnormality, in which at least one of the plurality of monitoring means , an in-vehicle monitoring means installed in a vehicle parked in a parking place of a building that can communicate with other monitoring means of the interlocking group, the in-vehicle monitoring means transmits a group separation signal when the vehicle starts to be used; When the use of the vehicle is stopped, a group return signal is sent, and when the other monitoring means in the interlocking group receives a group withdrawal signal from the on-board monitoring means, the on-board monitoring means is removed from the interlocking group, and the on-board monitoring means is removed from the on-board monitoring means. Since the in-vehicle monitoring device is returned to the linked group when a group return signal is received, even if the vehicle equipped with the in-vehicle monitoring device leaves the parking area on the premises and loses communication with the monitoring device inside the residence. When the vehicle starts to be used, such as by starting the engine, the in-vehicle monitoring means automatically leaves the interlocking group, and a degenerate interlocking group is created with the monitoring means installed in the house, which cannot communicate with the in-vehicle monitoring means. Even if it disappears, it will not cause a system failure indicating an abnormality in the interlocking group, and for example, fire monitoring in a house can be continued normally.

Additionally, when a vehicle equipped with an on-vehicle monitoring device returns to a parking spot on the premises and stops using the vehicle, the on-vehicle monitoring device automatically returns to the interlocking group, and fire monitoring by the interlocking group including vehicle fire monitoring is performed. is possible.

(Effects of leaving and returning to the group by confirming communication with the linked group)
Furthermore, the in-vehicle monitoring means transmits a group confirmation signal prior to transmitting the group withdrawal signal, transmits the group withdrawal signal when receiving a confirmation response signal from any of the other monitoring means, and transmits the group return signal before transmitting the group return signal. A group confirmation signal is sent in advance, and a group return signal is sent when a confirmation response signal is received from any of the other monitoring means, so the vehicle is placed in a location other than a residential site where communication with the interlocking group is not possible. When the vehicle is parked, a confirmation response signal is not received even if a group confirmation signal is transmitted when the vehicle is stopped and started, and it is possible to prevent unnecessary transmission of a group departure signal or a group return signal.

(Effects due to detection of start and stop of vehicle use)
Furthermore, the in-vehicle monitoring means detects a predetermined use start operation, which includes starting the vehicle engine and releasing the manual brake, as the start of use of the vehicle, and detects a predetermined use start operation, which includes stopping the vehicle engine and activating the manual brake, as the start of use of the vehicle. Since the predetermined stop operation is detected, there is no need for any special operation to detect the start of vehicle operation. can be detected and automatically leave and return to the linked group.

(Effects of detecting the start and stop of vehicle use using an electric cigarette ignition device)
In addition, the on-vehicle monitoring means includes a sensor unit that detects the start and stop of vehicle use by supplying and cutting off vehicle power to the electric cigarette ignition device mounted on the vehicle, and the sensor unit is detachable from the cigarette lighter socket of the electric cigarette ignition device. It is freely attached and operates by supplying vehicle power to wirelessly transmit a start-of-use signal to the on-vehicle monitoring means, and the on-vehicle monitoring means transmits a group separation signal when receiving the start-of-use signal from the sensor unit. , the group return signal is sent when the reception of the start-of-use signal from the sensor unit continues and stops, so there is no need to install new sensors or equipment on the vehicle side, and the cigarette lighter socket Simply by attaching the sensor unit to the vehicle, when the engine starts and the cigarette lighter socket is energized, a start signal is sent to the in-vehicle monitoring means, and a group withdrawal signal is sent to the monitoring means in the house, automatically leaving the linked group. can be done.

In addition, when the vehicle engine is turned off, the power supply to the cigarette lighter socket stops, the sensor unit stops operating, and the start-of-use signal is cut off.This is detected and the group return signal is sent to the monitoring means in the house. sent and can be automatically returned to the linked group.

(Effect on communication test)
Furthermore, the plurality of monitoring means including the in-vehicle monitoring means periodically send and receive test signals to and from each other to perform a communication test, and if there is at least one monitoring means that cannot send and receive test signals, a communication error is reported. , the monitoring means other than the on-vehicle monitoring means excludes the on-vehicle monitoring means from the communication test when receiving the group leaving signal from the on-vehicle monitoring means, and excludes the on-vehicle monitoring means from being subject to the communication test when receiving the group return signal. Since it is included in the communication test, even if a vehicle equipped with in-vehicle monitoring means leaves the parking area on the premises and communication with the interlocking group is cut off, a communication error will not occur when the communication test is performed. Even if communication with the in-vehicle monitoring means becomes impossible, the remaining monitoring means can form an interlocking group to monitor fires in the house without causing communication errors as system failures.

(Effect on retransmission of interlocking signals)
Furthermore, when multiple monitoring means including on-vehicle monitoring means transmit predetermined interlocking signals including fire interlocking signals, they retransmit interlocking signals when they do not receive interlocking response signals from all of the other monitoring means. When the monitoring means other than the on-vehicle monitoring means receives the group leaving signal from the on-vehicle monitoring means, the on-vehicle monitoring means is excluded from the target for retransmitting the interlocking signal, and the monitoring means other than the on-vehicle monitoring means receives a group return signal from the on-vehicle monitoring means. When the on-vehicle monitoring means is included in the retransmission of interlocking signals, the vehicle equipped with the on-board monitoring means leaves the parking area on the premises and communication with the interlocking group is cut off. Even if the monitoring means that detects a fire sends a fire interlocking signal and no interlocking response signal is received from the on-vehicle monitoring means, the remaining monitoring means form an interlocking group and send the fire interlocking signal without causing a system failure. To make it possible to reliably perform a retransmission operation for reception by all monitoring means.

(Effects of on-vehicle monitoring means)
In another embodiment of the present invention, the vehicle-mounted monitoring means belongs to an interlocking group formed by a plurality of monitoring means installed in a predetermined monitoring area including a building, and is installed in a vehicle to monitor fires. When the vehicle starts to be used, a group withdrawal signal is sent to other monitoring devices belonging to the interlocking group to remove the group from the interlocking group, and when the vehicle stops being used, the group separation signal is sent to other monitoring devices belonging to the interlocking group. Since a group separation/return control section is provided that sends a group return signal to return from the interlocking group, the same effect as the vehicle-mounted monitoring means provided in the above-mentioned alarm system can be obtained.

[ Alarm system]
FIG. 1 is an explanatory diagram showing an embodiment of an alarm system forming an interlocking group, taking as an example an alarm system composed of wireless alarms (residential fire alarms) installed in houses and vehicles. .

[Basic concept of embodiment]
The basic concept of the alarm system according to the present embodiment is that an interlocking group is formed by a plurality of wireless alarm devices that function as monitoring means installed in the monitoring area of the house 11 etc. (inside the house 11 and its premises). , an alarm system that monitors and issues an alarm for a predetermined abnormality, such as a fire, in which at least one of the plurality of alarms is located at a parking location (in an area where it can communicate with the other alarms 10-1 to 10-4 in the interlocking group). This is an in-vehicle alarm 12 that functions as an in-vehicle monitoring means mounted on a vehicle 14 parked in a parking space or garage, etc., and the in-vehicle alarm 12 transmits a group separation signal when the vehicle 14 starts to be used. When the use of the vehicle 14 is stopped, a group return signal is transmitted, and when the other alarm devices 10-1 to 10-4 in the interlocking group receive a group separation signal from the on-board alarm device 12, they transmit the on-board alarm device 12. The vehicle alarm device 12 is removed from the linked group, and when a group return signal is received from the vehicle alarm device 12, the vehicle alarm device 12 is returned to the linked group.

As a result, the on-vehicle alarm 12 is installed in the vehicle 14, the fire in the vehicle 14 is monitored by the interlocking group, and the vehicle 14 with the on-vehicle alarm 12 installed leaves the parking place and the alarm 10-1 in the house is installed. Even if communication with the alarm 10-4 becomes impossible, when the vehicle 14 starts to be used, such as by starting the engine, the in-vehicle alarm 12 automatically leaves the interlocking group, and the alarm 10 installed in the house 11 A degenerate interlocking group from -1 to 10-4 is formed, and system failures such as communication errors do not occur, and fire monitoring within the house 11 by group interlocking can be continued normally.

Furthermore, when the vehicle 14 equipped with the on-vehicle alarm 12 returns to the parking place and stops using the vehicle 14, the on-vehicle alarm 12 automatically returns to the interlocking group, and the on-board alarm 12 automatically returns to the interlocking group, including the fire monitoring of the vehicle 14. Enables fire monitoring.

[Overview of alarm system]
As shown in Figure 1, wireless alarms 10-1 to 10-4 are installed in each room of the house 11, such as the kitchen, living room, master bedroom, children's room, etc., to detect and warn of fire. A wireless in-vehicle alarm 12 is installed in a vehicle 14 parked at a parking place such as an outdoor parking space or a garage within the premises of No. 11.

The alarm devices 10-1 to 10-4 and the vehicle-mounted alarm device 12 have a function of mutually transmitting and receiving interlocking signals such as fire signals by radio, and monitor fires in the house 11 and the vehicle 14. Also. The alarm devices 10-1 to 10-4 and the vehicle alarm device 12 form a linked group by using the same channel frequency and setting a predetermined group address. In this embodiment, the maximum number of alarm devices forming a linked group is, for example, 15. Further, in the following explanation, when there is no need to distinguish between the alarm devices 10-1 to 10-4 installed in the house 11, they may be referred to as the alarm device 10.

Each of the alarm devices 10-1 to 10-4 and the vehicle alarm device 12 registers a unique group address G and terminal addresses A1 to A5, thereby forming an interlocking group that can communicate signals with each other. Here, the terminal addresses of the alarm devices 10-1 to 10-4 are assumed to be A1 to A4, and the terminal address of the vehicle-mounted alarm device 12 is assumed to be A5.

If a fire breaks out in the room in which the alarm 10-1 is installed in the house 11, the alarm 10-1 detects the fire and outputs a fire alarm indicating the source of the alarm by means of an alarm sound and an alarm display. Further, the alarm 10-1 that has detected a fire wirelessly transmits a fire interlock signal in which a group address and a terminal address are set to the other alarms 10-2 to 10-4 and the vehicle-mounted alarm 12.

When the other alarm devices 10-2 to 10-4 and the on-vehicle alarm 12 receive a fire interlock signal from the alarm device 10-1 that is the interlock source, they output a fire alarm indicating the interlock destination with an alarm sound and an alarm display. do.

When the alarms 10-1 to 10-4 and the on-vehicle alarm 12 perform an alarm stop operation while a fire alarm is being output, they stop their own alarms and transmit the alarm stop interlock signal with the group address and terminal address set to other devices. It is sent to the alarm device and causes the alarm to stop. In addition, when the alarm 10-1 that detected the fire detects fire recovery, it stops its own alarm and sends a fire recovery interlock signal with the group address and terminal address set to the other alarms 10-2 to 10-. 4 and the vehicle-mounted alarm 12 to perform an alarm stop operation.

Furthermore, if a fire occurs in the vehicle 14, the on-vehicle alarm 12 detects the fire and outputs a fire alarm indicating the interlocking source with an alarm sound and an alarm display, and the alarms 10-1 to 10 installed in the house 11 -4, transmits a fire interlock signal indicating a fire with the group address and terminal address set by radio.

When the alarms 10-1 to 10-4 in the house 11 receive a fire interlocking signal from the vehicle-mounted alarm 12, which is the interlocking source, they output a fire alarm indicating the interlocking destination using an alarm sound and an alarm display. Furthermore, when a fire interlock signal is received from the on-vehicle alarm 12, the on-board alarm 12 is determined from the terminal address A5 included in the fire interlock signal, and a linked destination alarm including a voice message indicating a vehicle fire is output. good.

Further, in the normal monitoring state, the alarm devices 10-1 to 10-4 and the on-vehicle alarm device 12 automatically perform a communication test (regular notification test), for example, every 72 hours. Further, the alarm devices 10-1 to 10-4 and the on-vehicle alarm device 12 can perform a communication test by pressing and holding the test switch.

On the other hand, the vehicle 14 in which the on-vehicle alarm 12 is installed is provided with a sensor unit 16 that detects when the vehicle 14 starts to be used and when it stops being used. The sensor unit 16 is attached to the cigarette lighter socket of the vehicle 14, detects the supply of vehicle power to the cigarette lighter socket when the engine is started, and wirelessly transmits a usage signal to the on-vehicle alarm 12. Note that while the engine is operating, the sensor unit 16 continuously or periodically transmits a usage signal, and the on-vehicle alarm 12 determines that the vehicle 14 is in use.

When the in-vehicle alarm device 12 receives the usage signal from the sensor unit 16, it sends a group separation signal to the alarm devices 10-1 to 10-4 of the interlocking group installed in the house 11, and removes the in-vehicle alarm device 12 from the interlocking group. make them leave.

Here, the separation of the in-vehicle alarm 12 from the linked group means that the in-vehicle alarm 12 is removed from among the terminal addresses A1 to A5 registered in the alarms 10-1 to 10-4 to form the linked group. This means that the terminal address A5 is hidden or invalidated, for example, by mask processing or flag bit processing, and is excluded from communication tests and interlock signal transmission destinations.

In this way, when the engine of the vehicle 14 is started and the vehicle 14 is used, the on-board alarm 12 is automatically separated from the linked group, and when the vehicle 14 leaves the premises, the alarm 10-1 of the linked group is automatically removed. Even if it becomes impossible to communicate with ~10-4, it is excluded from the communication test, thereby preventing a communication error from occurring even if the communication test is performed.

Furthermore, when the vehicle 14 returns to the premises and the engine is turned off to stop or end the use of the vehicle 14, the sensor unit 16 stops transmitting the usage signal. When the in-vehicle alarm 12 determines that the reception of the use signal from the sensor unit 16 has stopped, the vehicle 14 has returned to the communication area of the interlocking group, so the alarm 10 of the interlocking group installed in the house 11 is activated. A group return signal is sent to units 1 to 10-4 to return the vehicle alarm 12 to the linked group.

Here, returning the in-vehicle alarm device 12 to the linked group means to enable the terminal address A5 of the in-vehicle alarm device 12, which was hidden or disabled when leaving the group, by canceling mask processing or flag bit processing, and This means returning the alarm device 12 to the communication test or interlocking signal transmission destination.

The on-vehicle alarm 12 must be able to communicate with any of the alarms 10-1 to 10-4 installed in the house 11 in order to transmit the group departure signal and group return signal upon the start and end of use of the vehicle 14. It is desirable to transmit after confirming that the vehicle 14 is within communication range of the linked group.

For this reason, the on-vehicle alarm 12 transmits a group confirmation signal to the alarms 10-1 to 10-4 before sending a group withdrawal signal or a group return signal, and when it receives a confirmation response signal, it sends a group withdrawal signal or a group return signal. When a signal is transmitted and an acknowledgment signal is not received, the group leaving signal or group return signal is not transmitted.

Thereby, when the vehicle 14 is stopped at a remote location where communication with the interlocking group is not possible while the vehicle 14 is in use, it is possible to prevent unnecessary transmission of a group departure signal and a group return signal.

[Alarm]
(Functional configuration of alarm)
FIG. 2 is a block diagram showing the functional configuration of an alarm device installed in a house. As shown in FIG. 2, the alarm device 10 includes a control processor 18, the control processor 18 is provided with a CPU 24, and a bus 32 from the CPU 24 is connected to a control logic 26, a ROM 28, and a RAM 30. Note that the control logic 26 implements various hardware functions such as bus control accompanying control processing by the CPU 24.

Connected to the bus 32 are a communication section 20, a smoke detection section 34, a test switch 36, an indicator light 38, a speaker 40, a registration switch 42, and a nonvolatile memory 44 provided outside the control processor 18.

The smoke detection section 34 has a known scattered light type smoke detection structure, and intermittently drives a light emitting section using an infrared LED to emit light at a predetermined period, and detects a light reception signal of the scattered light received by a light receiving section such as a photodiode. and outputs a smoke concentration detection signal. Note that a temperature detection section may be provided in place of the smoke detection section 34, and the temperature detection section uses, for example, a thermistor as a temperature detection element. Outputs a detection signal.

The communication unit 20 is connected to an antenna 22 and transmits and receives interlocking signals such as fire signals to and from other alarm devices 10 and the vehicle-mounted alarm device 12 according to a predetermined communication protocol. In Japan, this communication protocol complies with STD-30 (wireless equipment standard for specified low power security system wireless stations), which is known as a standard for specified low power wireless stations in the 426 MHz band, for example.

Specified low-power security system radio station equipment in the 426 MHz band has 48 channels with a frequency bandwidth of 12.5 kHz allocated between 426.2500 MHz and 426.8375 MHz, and any channel frequency can be used by multiple alarm devices. Use by assigning it to a linked group consisting of.

The communication unit 20 also includes a wireless transmission unit and a wireless communication unit, and the wireless transmission unit MSK modulates a data signal such as a fire interlock signal, then FM modulates it and transmits it from the antenna 22 as a signal radio wave with an assigned channel frequency in the 426 MHz band. The radio receiving unit receives the signal radio waves transmitted by the other alarm devices 10 and the vehicle alarm device 12 through the antenna 22, performs FM demodulation, then performs FSK demodulation, and further performs bit determination to detect fire-related signals, etc. Demodulate the data signal.

The CPU 24 is provided with the functions of a fire control section 46 and a group management control section 48, which are realized by executing programs stored in the ROM 28.

(Functions of fire control section)
The control function of the fire control unit 46 provided in the CPU 24 is as follows. The fire control unit 46 converts and reads the smoke concentration detection signal output from the smoke detection unit 34, detects a fire when the smoke concentration is equal to or higher than a predetermined threshold, and outputs a fire alarm indicating the interlock source. control.

When outputting a fire alarm, the fire control unit 46 instructs the communication unit 20 to generate a fire interlock signal in which the group address and its own terminal address are set, and sends a fire alarm signal to other alarm devices 10 and the vehicle alarm 12. Control is performed to transmit the interlocking signal, and other alarm devices 10 and vehicle-mounted alarms 12 that have received the fire interlocking signal output a fire alarm indicating the interlocking destination.

In addition, when the communication unit 20 receives a fire interlock signal transmitted from another alarm 10 in the house 11 that belongs to the same interlock group or from the on-vehicle alarm 12 disposed in the vehicle 14, the fire control unit 46 selects the interlock destination. Control is performed to output the fire signal shown.

In addition, the fire control unit 46 also uses the communication unit 20 to issue an alarm regarding alarm stop control by operating the test switch 36 and fire recovery control in which the smoke concentration of the smoke detection unit 34 drops below a threshold value. Transmits stop interlocking signals and fire recovery interlocking signals.

(Group management control section)
The control functions of the group management control unit 48 provided in the CPU 24 are as follows. In order to form an interlocking group with the alarms 10-1 to 10-4 and the on-vehicle alarm 12 shown in FIG. For example, after pressing the registration switch 42 of the alarm 10-1, the other alarms 10-2 to 10-4 and the vehicle-mounted alarm 12 are registered within a predetermined time, for example, within 60 seconds, with the battery power turned on. Press switch 42.

The group management control unit 48 of the alarm device 10-1 assigns the unregistered group address a predetermined group address G based on a predetermined rule, for example, the unique serial number stored in the alarm device 10-1. It generates and registers it in the group management information 50, and also generates its own unregistered terminal address A1 and registers it in the group management information 50.

Subsequently, the group management control unit 48 transmits a registration signal including the group address G and its own terminal address A1 to the other alarm devices 10-2 to 10-4 and the in-vehicle alarm device 12, and updates each group management information 50. to register.

When the same operation is repeated for the remaining alarm devices 10-2 to 10-4 and the vehicle alarm 12 to complete the group registration, the group management information 50 of the alarm devices 10-1 to 10-4 and the vehicle alarm 12 is , the group address G and terminal addresses A1 to A5 constituting the linked group are registered.

Furthermore, when the group management control unit 48 of the alarm device 10 receives a group withdrawal signal including the terminal address A5 from the on-vehicle alarm device 12, the group management control section 48 registers it in the group management information 50 in order to cause the on-vehicle alarm device 12 to leave the linked group. For example, the terminal address A5 of the in-vehicle alarm 12 that is installed is invalidated by mask processing, and the interlocking group is reduced to an interlocking group consisting of the alarms 10-1 to 10-4 installed in the house 11, which are made up of terminal addresses A1 to A4. control.

Furthermore, when the group management control unit 48 of the alarm device 10 receives a group return signal including the terminal address A5 from the on-vehicle alarm device 12 in a state where the interlocking group is degraded, the group management control unit 48 of the alarm device 10 causes the on-vehicle alarm device 12 to return from the interlocking group. Therefore, the mask process that disables the terminal address A5 of the in-vehicle alarm 12 registered in the group management information 50 is canceled, and the interlocking group is changed to the alarm 10- installed in the house 11 consisting of the terminal addresses A1 to A5. 1 to 10-4 and the on-vehicle alarm 12 are controlled to return to the interlocking group.

In addition, when the group management control unit 48 causes the in-vehicle alarm device 12 to leave and return from the linked group, a flag bit is provided corresponding to the terminal address A5 of the in-vehicle alarm device 12 registered in the group management information 50. The flag bit may be set to 0 as invalid and removed from the linked group, and the flag bit as 1 may be set as valid and returned to the linked group.

A sensor communication section 58 that connects the sensor control section 56 and antenna 60 shown in FIG.

When the unit body 62 of FIG. 4 is inserted into the cigarette socket 72, the electrode pin 66 provided on the unit body 62 is connected to the positive side of the socket, and the spring electrode 68 is connected to the negative side of the socket.

When the engine of the vehicle 14 is started, vehicle power is supplied to the cigarette socket 72, and when the engine is stopped, the supply of vehicle power is stopped. Therefore, when the engine of the vehicle 14 is started with the sensor unit 16 inserted into the cigarette lighter socket 72, vehicle power is supplied to the sensor unit 16 through the cigarette lighter socket 72, and the sensor unit 16 operates.

When the sensor unit 16 shown in FIG. 3 is operated by being supplied with vehicle power through the power connector section 54 when the engine of the vehicle 14 is started, the sensor communication section 58 transmits a usage signal in response to an instruction from the sensor control section 56. , the in-vehicle alarm 12 determines the start of use of the vehicle, and transmits a group leaving signal.

The sensor communication unit 58 is based on STD-30 (wireless equipment for specified low-power security system wireless stations), which is known as the standard for specified low-power wireless stations in the 426 MHz band, which is the same as the communication unit 20 of the in-vehicle alarm 12 shown in FIG. Since the communication area is narrow within the vehicle, the transmission power is set to be low. Furthermore, when the sensor control unit 56 operates due to the supply of vehicle power, it instructs the sensor communication unit 58 to repeatedly transmit a usage signal at a predetermined period.

When the engine of the vehicle 14 is stopped, the supply of vehicle power to the cigarette lighter socket 72 is stopped, the periodic transmission of usage signals from the sensor unit 16 is stopped, and the transmission of usage signals from the sensor unit 16 to the in-vehicle alarm 12 is stopped. Based on the continuous stoppage, it is determined that the vehicle 14 has stopped being used, that is, the engine has stopped, and a group return signal is sent.

(Group separation/return control unit)
When the group departure return control unit 52 of the on-vehicle alarm device 12 first receives the use signal from the sensor unit 16, it instructs the communication unit 20 to perform control to transmit a group departure signal, and controls the alarm device that has received the group departure signal. 10 performs control to invalidate the terminal address of the vehicle alarm device 12 registered in the group management information 50 by mask processing or the like and to cause it to leave the linked group.

Here, if the sensor unit 16 is periodically (intermittently) transmitting the usage signal, the group separation/return control unit 52 retrigger starts the timer when the usage signal is periodically received, and the usage signal is transmitted. When the signal is no longer received, the timer is no longer retrigger-started, and therefore control is performed to determine whether the vehicle 14 has stopped based on the time-up output of the timer and to transmit a group return signal.

Further, when the group leaving/returning control section 52 first receives a use signal from the sensor unit 16 or when the reception of the use signal stops, it transmits a group confirmation signal and sends a group confirmation signal to the alarm device 10-1 installed in the house 11. ~10-4. Control to transmit a group departure signal or group return signal when an acknowledgment signal is received from any one of 10-4, and not to transmit a group departure signal or group return signal when an acknowledgment signal is not received. conduct. This prevents unnecessary transmission of group departure signals and group return signals due to the start and end of use when the vehicle is parked outside the threshold and away from the communicable area of the interlocking group.

In addition, since the group address is set in the signal sent from the in-vehicle alarm 12 when the vehicle is parked in a location far from the communication area of the interlocking group, it is important to note that the group address is set in the signal sent from the vehicle alarm 12 when the vehicle is parked in a location away from the communicable area of the interlocking group. Even if there are homes or facilities that have alarm systems installed in different interlocking groups, having different group addresses will reliably prevent malfunctions due to signal exchange between different interlocking groups.

Further, the group leaving/returning control unit 52 may perform control to stop the communication operation of the communication unit 20 after transmitting the group leaving signal due to the start of use of the vehicle and until it is determined to stop using the vehicle. .

That is, when the group leaving/returning control unit 52 receives a usage signal from the sensor unit 16 and transmits a group leaving signal when the engine starts, it stops the operation by, for example, stopping the power supply to the communication unit 20, and the engine starts. When the reception of the use signal from the sensor unit 16 is continuously stopped due to the stoppage of the vehicle, and it is determined that the use of the vehicle is stopped, power supply to the communication section 20 is restarted, and control is performed to transmit a group return signal. Thereby, by not operating the communication unit 20 while the in-vehicle alarm device 12 is separated from the interlocking group, unnecessary communication such as communication tests can be eliminated and power consumption can be reduced.

[Management control of interlocking groups associated with vehicle use]
FIG. 5 is a time chart showing the departure and return of the in-vehicle alarm to the interlocking group as the vehicle is used.

As shown in FIG. 5, when the vehicle 14 is parked within the premises of the residence 11, the alarms 10-1 to 10 installed in the residences 11 with terminal addresses A1 to A5 forming the interlocking group A communication test shown in steps S1 to S5 is performed between the vehicle alarm 10-4 and the on-vehicle alarm 12 once every 72 hours, for example.

Next, as shown in step S6, when the engine is started in order to use the vehicle 14, the sensor unit 16 operates by supplying vehicle power to the cigarette lighter socket 72 by starting the engine, and sends a use signal in step S7. It is transmitted to the on-vehicle alarm 12.

When the in-vehicle alarm 12 receives the usage signal from the sensor unit 16, it determines that the vehicle 14 has started to be used, and in step S8 sends a group separation signal to the alarms 10-1 to 10-4 installed in the house 11. Then, as shown in steps S9 to S12, the in-vehicle alarm device 12 is removed from the linked group by invalidating the terminal address A5 by masking or the like.

Therefore, even if a communication test is performed on the alarms 10-1 to 10-4 installed in the house 11 in a state where communication with the on-vehicle alarm 12 becomes impossible due to the use of the vehicle 14, no communication error will occur. The communication test can be completed normally.

Furthermore, when the on-vehicle alarm 12 is separated from the interlocking group, for example, if the alarm 10-1 detects a fire and outputs a fire alarm indicating the interlocking source, the fire interlocking signal is transmitted to the other alarms 10-2 to 10-1. 10-4 to output the linked destination alarm. The interlocking source alarm 10-1 determines whether or not an acknowledgment signal is received from an interlocking destination, and if acknowledgment signals are not obtained from all transmission sources, the fire interlocking signal is repeatedly retransmitted.

At this time, an acknowledgment signal is not received from the in-vehicle alarm device 12 which is separated from the interlocking group and cannot communicate, but since the in-vehicle alarm device 12 has left the interlocking group, acknowledgment signals are normally obtained from all interlocking destinations. Therefore, it is possible to reliably prevent a system error (system failure) in which the fire-linked signal is repeatedly retransmitted without receiving an acknowledgment signal from the on-vehicle alarm 12.

Subsequently, when the vehicle 14 returns to the premises and stops the engine in step S13, the sensor unit 16 stops transmitting the usage signal in step S14, and the on-vehicle alarm 12 detects the engine from the continuous stoppage of the usage signal. After determining the stop, in step S15, a group return signal is sent to the alarms 10-1 to 10-4 installed in the house 11, and as shown in steps S16 to S19, the masking process for the terminal address A5 is canceled. By activating it, the in-vehicle alarm 12 is returned to the linked group.

[Modification of the present invention]
(Detection of start and stop of vehicle use)
In the embodiment described above, the start and stop of use of the vehicle is detected by starting and stopping the engine, but the invention is not limited to this, and the use of the vehicle is detected by releasing the manual brake, and by the activation of the manual brake. Stoppage of use of the vehicle may also be detected.

In addition, since liquid crystal displays are displayed on meter panels such as speedometers when using a vehicle, a light receiving section was installed as a sensor unit to optically detect the brightness of the meter panel display, and a light reception signal was obtained. Alternatively, the use of the vehicle may be detected, and if the light reception signal is continuously cut off, the stoppage of use of the vehicle may be detected. As a result, by simply attaching the sensor unit externally, it is possible to easily detect when the vehicle is in use and when it is no longer in use, and to transmit a group departure signal and a group return signal from the on-vehicle alarm.

(vehicle alarm)
The above embodiment takes as an example a case where an interlocking group is formed by an in-vehicle alarm installed in one vehicle and an alarm installed in a house, but the invention is not limited to this, and each alarm installed in multiple vehicles is used as an example. An interlocking group may be formed by an in-vehicle alarm and an alarm installed in a house.

(parent-child method)
In the above embodiment, when multiple alarms are installed in a house and car alarms are placed in a vehicle to form an interlocking group, each alarm can communicate with each other without distinguishing between a master unit and a slave unit. However, a master unit and multiple slave units are installed to form an interlocking group, and each group's master unit is given a repeater function, so that interlocking alarms can be created between the master units of different groups. Communication may also be performed. In this case, the main unit is an alarm installed in the house.

(Alarm)
The above embodiment takes as an example a wireless alarm that detects and warns of fire, but other than the alarm, wireless fire alarms, gas leak alarms, CO alarms, and various other types of alarms may also be used. The present invention can be similarly applied to alarm systems equipped with crime prevention alarms and systems including multiple alarms.

Furthermore, although the above embodiment takes as an example a wireless alarm device in which a sensor section and an alarm output processing section are provided as one unit, other embodiments include a case in which a sensor section and an alarm output processing section are provided separately. It may also be a wireless alarm.

(Vehicle alarm and sensor unit)
In the embodiment described above, the on-vehicle alarm 12 provided in the vehicle and the sensor unit 16 are connected wirelessly, but a wired communication connection using a signal line may also be used.

Further, the on-vehicle alarm 12 may be any of various crime prevention alarms such as a theft alarm.

(Serial ID)
In the above embodiment, when the alarm 10 installed in a house receives a group separation signal from the on-vehicle alarm 12, the on-vehicle alarm 12 is excluded from the linked group, and when the group return signal is received, the on-vehicle alarm 12 is returned to the linked group. However, the present invention is not limited to this, and a serial ID (a unique identifier given at the time of manufacture) is included in the croup separation signal and group return signal from the on-vehicle alarm 12 and transmitted, and the alarm 10 of the house 11 When a group leaving signal is received, the in-vehicle alarm 12 is removed from the linked group and the received serial ID is stored, and when a group return signal is received, the received serial ID and the stored serial ID match. It may also be possible to return the group to the linked group.

(In-vehicle alarm interlocking alarm)
In the embodiment described above, a fire alarm is output when the in-vehicle alarm 12 receives a fire interlock signal from the alarm 10 of the house 11, but there is a low possibility that there are people in the parked vehicle, and Since it would be a nuisance if a fire alarm inside the house 11 is reported to the outside, a fire alarm may not be output when the on-vehicle alarm 12 receives a fire interlock signal.

(others)
Further, the present invention is not limited to the above-described embodiments, but includes appropriate modifications without impairing the objects and advantages thereof, and is not limited by the numerical values shown in the above-described embodiments.
