Description

  The present invention relates to an alarm system that performs a fire alarm with a plurality of alarm devices that wirelessly communicate with each other.

  In a conventional alarm system, for example, “a plurality of fire alarms that transmit radio signals using radio waves as a medium, and a radio signal transmitted from any one of the fire alarms is relayed to any other fire alarm. When the receiving device receives a wireless signal including a fire alarm message transmitted from a fire alarm device registered in advance among other fire alarm devices, the fire device receives the fire signal. "A wireless signal including an alarm message is transmitted from a transmission means" has been proposed (for example, see Patent Document 1).

Embodiment 1 FIG.
(Alarm system configuration)
FIG. 1 is a diagram showing a configuration of an alarm system according to Embodiment 1 of the present invention.
The alarm system in the present embodiment includes a plurality of fire alarms and a relay adapter 30.
Each fire alarm and the relay adapter 30 function as, for example, a “power-saving radio station” defined in Article 4 item 3 of the Radio Law, and between each fire alarm (including the relay adapter 30). The distance at which wireless signals can be transmitted and received is limited.

In addition, any one of the plurality of fire alarms operates as the parent device 10, and the other alarm devices operate as the child device 20.
The setting of the master unit 10 is completed by, for example, pressing a registration button (not shown) after turning on the power. On the other hand, the setting of the slave unit 20 in each fire alarm is completed by, for example, pressing a registration button (not shown) after the slave unit 20 is turned on in a state where the registration mode (not shown) of the master unit 10 is pressed to enter the registration mode. .
The master unit 10 and each slave unit 20 are assigned a group ID that is commonly set for a group that performs a fire alarm in conjunction with a self-address that is uniquely set for each fire alarm in the group. It is done. Further, a group ID and a self address are similarly assigned to the relay adapter 30 as well. That is, the master unit 10 communicates with the relay adapter 30 as one of the slave units. Note that group ID assignment may be omitted.
In FIG. 1, a suffix number corresponding to the self address is attached to the code in order to distinguish each slave unit 20.

When receiving the radio signal transmitted from the slave unit 20 or the relay adapter 30, the master unit 10 retransmits the radio signal to the slave unit 20 and the relay adapter 30.
Thereby, the subunit | mobile_unit 20 which can communicate directly with the main | base station 10 can mutually communicate wirelessly.
For example, as shown in FIG. 1, the slave units 20-1 to 20-4 arranged within the communication range of the master unit 10 can perform wireless communication with each other without using the relay adapter 30.
Hereinafter, the parent device 10 and the child device 20 capable of directly communicating with the parent device 10 are also referred to as “relay source alarm devices”.
On the other hand, the slave units 20-5 and 20-6 arranged outside the communication range of the master unit 10 can communicate with the relay source alarm device via the relay adapter 30.
Hereinafter, a fire alarm device that cannot directly communicate with the parent device 10 and is a relay target is also referred to as a “relay destination alarm device”.

In addition, although this Embodiment 1 demonstrates the case where the subunit | mobile_unit 20 as a relay destination alarm device is two units | sets, this invention is not limited to this, One unit | set may be sufficient and three or more units | sets are sufficient. There may be.
Although the case where there is one relay adapter 30 will be described, the present invention is not limited to this, and two relay adapters 30 may be installed within the communication range of the base unit 10.

  The relay adapter 30 relays a radio signal transmitted from any of a plurality of relay source alarm devices to the relay destination alarm device, and relays a radio signal transmitted from the relay destination alarm device to each of the plurality of relay source alarm devices. . Details will be described later.

  With such a configuration, the relay adapter 30 relays the wireless signal transmitted from the relay source alarm device or the relay destination alarm device that has detected a fire, thereby performing a fire alarm at the relay source alarm device and the relay destination alarm device. It becomes possible.

The “fire alarm” corresponds to the “alarm” in the present invention.
The “relay adapter 30” corresponds to the “relay device” in the present invention.

(Configuration of base unit 10 and handset 20)
FIG. 2 is a functional block diagram showing the main configuration of base unit 10 and handset 20 according to Embodiment 1 of the present invention.
In FIG. 2, the main unit 10 and the sub unit 20 include a control circuit 11, a battery 12, a power supply circuit 13, a battery voltage detection circuit 14, a transmission / reception circuit 15, an antenna 16, a fire detection circuit 17, an alarm sound control circuit 18, an indicator lamp. A circuit 19, a linked inspection switch 22, and a fire alarm sound output setting switch 23 are provided.

The battery 12 supplies DC power to the power supply circuit 13.
The power supply circuit 13 controls the voltage of the battery 12 to a predetermined voltage and supplies it to the control circuit 11, the transmission / reception circuit 15, the fire detection circuit 17, the alarm sound control circuit 18, and the indicator lamp circuit 19.

The battery voltage detection circuit 14 detects the voltage of the battery 12 applied to the power supply circuit 13 and outputs a battery voltage detection signal corresponding to the detected voltage to the control circuit 11.
When the battery voltage detection circuit 14 detects that the remaining battery level has dropped or exceeds the threshold value for running out of the battery, the control circuit 11 drives the alarm sound control circuit 18 and the indicator lamp circuit 19 and runs out of the battery. The transmission / reception circuit 15 outputs a state signal including the state information.

The fire detection circuit 17 detects a physical change such as smoke or heat based on a fire phenomenon and outputs a signal corresponding to the detected content to the control circuit 11.
The alarm sound control circuit 18 is a circuit for controlling the sounding operation of sound or the like by a buzzer / speaker or the like.
The indicator lamp circuit 19 is a circuit that controls the lighting operation of indicator lamps such as light emitting diodes.

The transmission / reception circuit 15 is connected to an antenna 16 for transmitting / receiving radio signals.
The transmission / reception circuit 15 processes the radio signal input from the antenna 16 and performs reception processing in the case of a signal addressed to itself. In the case of other signals, reception processing is not performed. The received signal is output to the control circuit 11.
In addition, the transmission / reception circuit 15 is controlled by the control circuit 11 to perform transmission processing of a signal such as a linked inspection signal described later.

The control circuit 11 controls the alarm sound control circuit 18 and the indicator lamp circuit 19 on the basis of the signal received by the transmission / reception circuit 15, and performs various alarms by sound and indicator lamps.
Moreover, while performing a required process based on the signal which the transmission / reception circuit 15 received, the transmission / reception circuit 15 is controlled as needed and signals, such as an interlocking inspection signal, are transmitted.

The storage unit 21 is a nonvolatile memory such as an EEPROM and stores programs executed by the control circuit 11 and various data.
Further, the storage unit 21 stores group ID and self address information.
The group ID is a unique ID assigned in common to fire alarms that operate in conjunction with a fire alarm. For example, in FIG. 1, a common group ID is set for the parent device 10 and the child devices 20-1 to 20-6 to configure one alarm device group.
The self address is an address uniquely set for each fire alarm and relay adapter 30.

  The interlocking inspection switch 22 is constituted by a push button switch, for example, and inputs an operation signal corresponding to the switch on / off operation to the control circuit 11 when the switch is turned on / off by the user.

The fire alarm sound output setting switch 23 is constituted by, for example, a changeover switch or the like, and sets whether or not to perform an acoustic alarm by, for example, a buzzer / speaker when receiving an interlock control signal.
In addition, it is good also as a structure which stores the fire alarm sound output setting state in the memory | storage part 21 previously at the time of factory shipment.

(Configuration of relay adapter 30)
The relay adapter 30 has a configuration in which the fire detection circuit 17 is not provided among the configurations of the master unit 10 and the slave unit 20.
The following description will be focused on the differences from the parent device 10 and the child device 20.

The storage unit 21 of the relay adapter 30 stores information on the self address assigned to the relay destination alarm device in addition to the group ID and the self address.
Acquisition of the self-address of the relay destination alarm device can be performed by obtaining information on whether communication with the parent device 10 is possible from each child device 20 in the registration mode, for example.
Moreover, it is good also as a structure which stores the information of the self-address allocated to the relay destination alarm device in the memory | storage part 21 previously at the time of factory shipment.
In the example of FIG. 1, “address 5” and “address 6”, which are self-addresses of the slave units 20-5 and 20-6 that are relay destination alarm devices, are stored.

(Linked inspection operation)
Next, the operation of the linked inspection will be described.
3-5 is a figure explaining the operation | movement of the interlocking inspection of the alarm system which concerns on Embodiment 1 of this invention.
FIG. 3 shows the flow of the interlock inspection signal when the interlock inspection switch 22 of the relay source alarm device is turned on.
FIG. 4 shows the flow of the interlock inspection signal when the interlock inspection switch 22 of the relay adapter 30 is turned on.
FIG. 5 shows the flow of the interlock inspection signal when the interlock inspection switch 22 of the relay destination alarm is turned on.
FIG. 6 is a diagram showing the contents of the interlocking inspection signal according to Embodiment 1 of the present invention.

In FIG. 3, when the interlock check switch 22 is turned on by the user, the slave unit 20-1 simulates the detection of a fire, and an alarm that the fire alarm device has detected a fire by voice or an indicator light (hereinafter referred to as a fire alarm). "Fire source alarm"). For example, a sound such as “It is a fire. It is a fire” is sounded and a red light is blinked. The ringing or display by this fire alarm is automatically stopped after a predetermined time.
Moreover, the subunit | mobile_unit 20-1 transmits the interlocking inspection signal 100 while performing alarm operation | movement itself. The interlock inspection signal 100 will be described with reference to FIG.

  As shown in FIG. 6, the interlocking inspection signal 100 for performing the interlocking inspection includes at least a group ID 101, a fire source AD (address) 102, a partner AD 103, and state information 104. Note that the group ID 101 may be omitted.

  In the group ID 101, information on the group ID stored in the storage unit 21 is set.

  The fire source AD 102 is set with a self-address of a fire alarm that simulates the detection of a fire. Here, “address 1”, which is the self address of the slave 20-1, is set.

The partner AD 103 sets the self-address of the fire alarm and the relay adapter 30 that perform the linked inspection. Here, since all the fire alarms and the relay adapter 30 perform the linked inspection, “all addresses” for designating all of the self-addresses assigned to the master unit 10, the slave unit 20, and the relay adapter 30 are set.
As described above, since the self-address of the relay adapter 30 is set as one of the addresses of the slave units, it is not necessary to distinguish between the fire alarm device and the relay adapter 30 in the partner AD 103.

  In the status information 104, information indicating the content of the radio signal is set. Since this is a linked inspection that simulates fire detection, it is set to “linked inspection”.

Next, when base unit 10 / slave unit 20-2 / slave unit 20-3 receives interlocking inspection signal 100, base unit AD 103 determines whether or not self-address is included in counterpart AD 103.
When the partner AD 103 includes a self-address, an alarm (hereinafter referred to as “linked alarm”) linked to the fire source alarm is performed by voice or an indicator lamp. For example, a sound such as “It is a fire in another place” is sounded and an orange light is turned on. Further, it is determined from the status information 104 that “linked inspection” is performed, and the linked alarm is automatically stopped after a predetermined time has elapsed.
On the other hand, if the counterpart AD 103 does not match, the received interlocking inspection signal 100 is discarded.
Note that an interlocking alarm may be issued when the group ID 101 matches the own group ID and the counterpart AD 103 matches.

Furthermore, when the base unit 10 receives the interlocking inspection signal 100, the base unit 10 retransmits the interlocking inspection signal 100 having the same content as the received interlocking inspection signal 100.
As a result, the interlock inspection signal 100 is received by all the fire alarms and relay adapters 30 of the slave unit 20 disposed within the communication range of the master unit 10.
For example, as shown in FIG. 3, even when the slave unit 20-1 and the relay adapter 30 cannot directly wirelessly communicate, the relay adapter 30 can receive the interlocking inspection signal 100 transmitted from the master unit 10. It becomes possible.

Next, the operation of the relay adapter 30 will be described.
FIG. 7 is a flowchart for explaining the operation of interlocking inspection of the relay adapter 30 according to the first embodiment of the present invention.
Hereinafter, description will be given based on each step of FIG.

(S101)
When the radio signal is received by the transmission / reception circuit 15, the control circuit 11 of the relay adapter 30 refers to the information in the state information 104 and determines whether or not it is a linked inspection signal.
When the interlocking inspection signal has not been received, the process proceeds to step S106.

(S102)
On the other hand, in the case of the interlock inspection signal, the control circuit 11 determines the output setting of the fire alarm sound output setting switch 23.
If the fire alarm sound output setting switch 23 is in the OFF state, that is, if it is set so as not to perform an acoustic alarm, the process proceeds to step S104.

(S103)
On the other hand, when the fire alarm sound output setting switch 23 is in the ON state, that is, when the setting is to perform an acoustic alarm, the control circuit 11 uses the alarm sound control circuit 18 to ring in conjunction with the fire source alarm (hereinafter referred to as “linked ringing”). .) For example, a sound such as “It is a fire in another place” is sounded.

(S104)
Next, the control circuit 11 causes the indicator lamp circuit 19 to perform a display linked to the fire source alarm (hereinafter referred to as “linked display”). For example, an orange lamp is turned on. The ringing or display by this interlocking alarm is automatically stopped after a predetermined time.

(S105)
Next, the control circuit 11 causes the transmission / reception circuit 15 to retransmit the interlocking inspection signal 100 having the same content as the received interlocking inspection signal 100.
Here, although it retransmits with respect to all the fire alarm devices, the structure which transmits only to the subunit | mobile_unit 20-5 * 20-6 as a relay destination alarm device may be sufficient.

The interlocking inspection signal 100 transmitted from the relay adapter 30 is received by the slave units 20-5 and 20-6 that are relay destination alarm devices.
And the subunit | mobile_unit 20-5 and 20-6 which received the interlocking | linkage inspection signal 100 will judge whether the other party AD103 contains a self address, if the interlocking | linkage inspection signal 100 is received.
When the partner AD 103 includes a self-address, an alarm (hereinafter referred to as “linked alarm”) linked to the fire source alarm is performed by voice or an indicator lamp. For example, a sound such as “It is a fire in another place” is sounded and an orange light is turned on. Further, it is determined from the status information 104 that “linked inspection” is performed, and the linked alarm is automatically stopped after a predetermined time has elapsed.
On the other hand, when the group ID 101 or the partner AD 103 does not match, the received interlocking inspection signal 100 is discarded.
Note that an interlocking alarm may be issued when the group ID 101 matches the own group ID and the counterpart AD 103 matches.

  In this way, the relay source alarm device outputs the interlocked inspection signal 100 to the other relay source alarm devices and the relay adapter 30 among the plurality of relay source alarm devices when the own interlocked inspection switch 22 is turned on. Send. Then, the relay adapter 30 relays the interlocking inspection signal 100 from the relay source alarm device to the relay destination alarm device. When the relay destination alarm device receives the interlock inspection signal 100 transmitted from the relay adapter 30, it performs an interlock alarm.

(S106)
When it is determined in step S101 that the interlock inspection signal has not been received, the control circuit 11 of the relay adapter 30 determines whether or not the interlock inspection switch 22 of the relay adapter 30 is turned on.
If the self-linkage inspection switch 22 is not on, the process returns to step S101 and the above operation is repeated.

(S107)
On the other hand, when the interlock inspection switch 22 of the relay adapter 30 is turned on, the control circuit 11 of the relay adapter 30 determines the output setting of the fire alarm sound output setting switch 23.
If the fire alarm sound output setting switch 23 is in the OFF state, that is, if it is set so as not to perform an acoustic alarm, the process proceeds to step S109.

(S108)
On the other hand, when the fire alarm sound output setting switch 23 is in the ON state, that is, when setting to perform an acoustic alarm, the control circuit 11 causes the alarm sound control circuit 18 to make a sound as a fire source alarm (fire source sound). . For example, it sounds like “fire.

(S109)
Next, the control circuit 11 causes the indicator lamp circuit 19 to display a fire source alarm (fire source display). For example, a red light is blinked.

  Thus, when the interlocking inspection switch 22 of the relay adapter 30 is turned on, the relay adapter 30 operates as a fire alarm device. The ringing or display by this fire alarm is automatically stopped after a predetermined time.

In the present embodiment, the case where the fire source alarm is performed when the interlocking inspection switch 22 of the relay adapter 30 is turned on has been described, but the present invention is not limited to this.
For example, interlocking sounding and interlocking display may be performed by the same operation as in steps S103 and S104.

(S110)
Next, the control circuit 11 of the relay adapter 30 causes the transmission / reception circuit 15 to transmit the interlocking inspection signal 100 to the relay destination alarm device.
The self-address of the relay adapter 30 is set in the fire source AD 102 of the interlocking inspection signal 100. For example, in FIG. 4, “7” that is a self-address as a slave unit is assigned to the relay adapter 30. Therefore, “address 7”, which is the self-address of the relay adapter 30, is set here.

Further, the self-address of the relay destination alarm stored in the storage unit 21 is set in the partner AD 103.
In the example of FIG. 4, “addresses 5 and 6” that specify the self-addresses of the slave units 20-5 and 20-6 that are relay destination alarm devices are set.

  The status information 104 is set to “linked inspection” in the same manner as described above.

  After transmitting the interlocking inspection signal 100, the control circuit 11 of the relay adapter 30 returns to step S101 and repeats the above operation.

As shown in FIG. 4, the interlocking inspection signal 100 transmitted from the relay adapter 30 is received by the slave units 20-5 and 20-6 that are relay destination alarm devices.
And the subunit | mobile_unit 20-5 and 20-6 which received the interlocking | linkage inspection signal 100 will judge whether the other party AD103 contains a self address, if the interlocking | linkage inspection signal 100 is received.
When the other party's AD 103 includes its own address, an interlocking alarm is given by voice or an indicator lamp. For example, a sound such as “It is a fire in another place” is sounded and an orange light is turned on. Further, it is determined from the status information 104 that “linked inspection” is performed, and the linked alarm is automatically stopped after a predetermined time has elapsed.
On the other hand, when the group ID 101 or the partner AD 103 does not match, the received interlocking inspection signal 100 is discarded.
Note that an interlocking alarm may be issued when the group ID 101 matches the own group ID and the counterpart AD 103 matches.

In this way, the relay adapter 30 transmits a linked inspection signal to the relay destination alarm device when its own linked check switch 22 is turned on. When the relay destination alarm device receives the interlock inspection signal transmitted from the relay adapter 30, it performs a fire alarm (interlock alarm).
At this time, the relay source alarm device does not receive (discard) the interlocking inspection signal 100, and therefore does not perform the interlocking alarm. That is, when the interlock inspection switch 22 of the relay adapter 30 is turned on, only the relay destination alarm device performs the interlock inspection.

In FIG. 5, when the interlock check switch 22 of the slave unit 20-5 is turned on by the user, the slave unit 20-5 simulates the detection of a fire and issues a fire source alarm by sound or an indicator lamp. For example, a sound such as “It is a fire. It is a fire” is sounded and a red light is blinked. The ringing or display by this fire alarm is automatically stopped after a predetermined time.
Moreover, the subunit | mobile_unit 20-5 transmits the interlocking inspection signal 100 while performing alarm operation | movement itself. This interlocking inspection signal 100 is the same as the interlocking inspection signal 100 transmitted by the above-described slave unit 20-1.

When receiving the interlock check signal 100, the slave unit 20-6 determines whether or not the partner AD 103 includes a self address.
When the other party's AD 103 includes its own address, an interlocking alarm is given by voice or an indicator lamp. For example, a sound such as “It is a fire in another place” is sounded and an orange light is turned on. Further, it is determined from the status information 104 that “linked inspection” is performed, and the linked alarm is automatically stopped after a predetermined time has elapsed.
On the other hand, if the counterpart AD 103 does not match, the received interlocking inspection signal 100 is discarded.
Note that an interlocking alarm may be issued when the group ID 101 matches the own group ID and the counterpart AD 103 matches.

  When relay adapter 30 receives linked inspection signal 100, relay adapter 30 performs linked ringing / linked display by the operations of steps S101 to S105 described above, and retransmits linked inspection signal 100 having the same contents as received linked inspection signal 100. To do.

The interlocking inspection signal 100 transmitted from the relay adapter 30 is received by the master unit 10 and the slave units 20-1 to 20-4, which are relay source alarm devices.
And the main | base station 10 and the subunit | mobile_unit 20-1 to 20-4 which received the interlocking | linkage inspection signal 100 judge whether a self address is contained in the other party AD103.
When the other party's AD 103 includes its own address, an interlocking alarm is given by voice or an indicator lamp. For example, a sound such as “It is a fire in another place” is sounded and an orange light is turned on. Further, it is determined from the status information 104 that “linked inspection” is performed, and the linked alarm is automatically stopped after a predetermined time has elapsed.
On the other hand, when the group ID 101 or the partner AD 103 does not match, the received interlocking inspection signal 100 is discarded.
Note that an interlocking alarm may be issued when the group ID 101 matches the own group ID and the counterpart AD 103 matches.
Furthermore, when the base unit 10 receives the interlocking inspection signal 100, the base unit 10 retransmits the interlocking inspection signal 100 having the same content as the received interlocking inspection signal 100.
As a result, the interlock inspection signal 100 is received by all the fire alarms and relay adapters 30 of the slave unit 20 arranged within the communication range of the master unit 10.

In this way, the relay destination alarm device transmits an interlocked inspection signal to the other relay destination alarm devices of the plurality of relay destination alarm devices and the relay adapter 30 when its own interlocked inspection switch 22 is turned on. To do.
Further, the relay destination alarm device performs a fire alarm (interlocking alarm) when it receives the interlock inspection signal transmitted from another relay destination alarm device or the relay adapter 30 among the plurality of relay destination alarm devices.
Moreover, the relay adapter 30 relays the interlocking inspection signal 100 from the relay destination alarm device to the relay source alarm device. When the relay source alarm device receives the interlock inspection signal 100 transmitted from another relay source alarm device or the relay adapter 30 among the plurality of relay source alarm devices, the relay source alarm device performs the interlock alarm.

  In the present embodiment, the case where there are a plurality of relay destination alarm devices has been described. However, the present invention is not limited to this, and a single alarm device may be used. In this case, when the interlock inspection switch 22 of the relay destination alarm is turned on, only the relay adapter 30 is designated as the counterpart AD and the interlock inspection signal 100 is transmitted.

  The “fire alarm” and the “linked alarm” in the present embodiment correspond to the “fire alarm” in the present invention.

As described above, in the present embodiment, the relay adapter 30 that relays between the relay source alarm device and the relay destination alarm device is provided, and the relay source alarm device has a plurality of relays when the self-linkage inspection switch 22 is turned on. A linkage inspection signal is transmitted to other relay source alarm devices and relay adapters 30 among relay source alarm devices, and transmitted from other relay source alarm devices or relay adapters 30 among a plurality of relay source alarm devices. When a linked inspection signal is received, a fire alarm is given. Also, the relay destination alarm device transmits a linked inspection signal to the relay adapter 30 when its own linked inspection switch 22 is turned on, and receives a linked inspection signal transmitted from the relay adapter 30 when it receives a fire alarm. I do.
For this reason, interlocking inspection can be carried out by the entire system of each fire alarm and relay adapter 30 constituting the alarm system.

Further, the relay adapter 30 transmits a linked inspection signal to the relay destination alarm device when its own linked inspection switch 22 is turned on.
For this reason, it is possible to carry out the linked inspection only for the relay destination alarm device among the fire alarm devices constituting the alarm system.

The relay destination alarm device includes a plurality of relay destination alarm devices. When the interlock inspection switch 22 of the relay destination alarm device is turned on, the relay destination alarm device is connected to the other relay destination alarm devices and the relay adapter 30 among the plurality of relay destination alarm devices. When a linked inspection signal transmitted from another relay destination alarm device or the relay adapter 30 among the plurality of relay destination alarm devices is received, a fire alarm is issued.
For this reason, even if there are a plurality of relay destination alarm devices, it is possible to carry out the linked inspection only for the relay destination alarm devices among the fire alarm devices constituting the alarm system.

Also, any relay source alarm device among the plurality of relay source alarm devices operates as the parent device 10, and other alarm devices operate as the child device 20, and the parent device 10 is connected to the slave device 20 or the relay adapter 30. When the transmitted interlocking inspection signal is received, the interlocking inspection signal is transmitted to the slave unit 20 and the relay adapter 30.
For this reason, for example, even if the handset 20 and the relay adapter 30 cannot directly wirelessly communicate, it is possible to transmit the interlocking inspection signal from the handset 20 to the relay adapter 30.

Embodiment 2. FIG.
(Alarm system configuration)
FIG. 8 is a diagram showing a configuration of an alarm system according to Embodiment 2 of the present invention.
The alarm system in the present embodiment includes alarm group A and alarm group B.
Alarm group A and alarm group B (hereinafter, also simply referred to as “alarm group” if not distinguished from each other) are composed of a plurality of fire alarms that communicate with each other wirelessly.
Each alarm group performs various alarms with each fire alarm in the alarm group by transmitting and receiving wireless signals between fire alarms (including the relay adapter 30 described later) in the same alarm group. Is.

  Among a plurality of fire alarms constituting the alarm group, the fire alarm capable of wireless communication with each fire alarm in the alarm group to which the alarm belongs belongs as the master unit 10 and the other fire alarms are slave units. It operates as 20. That is, the parent device 10 is a fire alarm device arranged at a position where it can wirelessly communicate with all the child devices 20 and the relay adapter 30 in the alarm device group.

The setting of the master unit 10 of each alarm device group is completed, for example, by pressing a registration button (not shown) after the power is turned on. On the other hand, the setting of the slave unit 20 in each fire alarm is completed by, for example, pressing a registration button (not shown) after the slave unit 20 is turned on in a state where the registration mode (not shown) of the master unit 10 is pressed to enter the registration mode. .
The master unit 10 and each slave unit 20 are assigned a group ID that is an ID inherent to the alarm device group and a self-address that is uniquely set for each fire alarm in the group.

In the alarm group, the number of fire alarms that can join the group is set (maximum number), and the load of wireless communication processing is reduced and address management of each alarm unit is simplified. For example, the maximum number that can join the alarm group is set to 15.
In addition, each fire alarm functions as a “power-saving radio station” stipulated in, for example, Article 4 item 3 of the Radio Law, and can transmit and receive radio signals between the fire alarms. The distance is limited.

Furthermore, the alarm device group A includes a relay adapter 30A, and the alarm device group B includes a relay adapter 30B.
The relay adapters 30A and 30B (hereinafter simply referred to as “relay adapter 30” if not distinguished from each other) receive relay check signals from the fire alarms of the alarm group to which the relay adapters 30A and 30B belong. An interlock inspection signal is transmitted to the adapter 30. Moreover, when the relay adapter 30 receives the interlock inspection signal from the relay adapter 30 of another alarm device group, the relay adapter 30 transmits the interlock inspection signal to the fire alarm device of the alarm device group to which the relay adapter 30 belongs. Details will be described later.

  In the present embodiment, the case where there are two alarm device groups will be described, but the present invention is not limited to this.

(Configuration of relay adapter 30)
Next, the configuration of the relay adapter 30 in the second embodiment will be described focusing on the differences from the first embodiment.
In addition, the structure of the main | base station 10 and the subunit | mobile_unit 20 is the same as that of the said Embodiment 1. FIG.

In the storage unit 21 of the relay adapter 30 according to the second embodiment, information on the individual ID of the relay partner and the information on the individual ID of the relay partner are stored in advance. The individual ID of the relay partner and the individual ID of the relay partner are stored, for example, at the time of factory shipment.
The relay adapter 30 is used in pairs with the relay adapter 30 that stores its own individual ID as the individual ID of the relay partner.
In the example of FIG. 8, since the relay adapter 30A and the relay adapter 30B are used in pairs, the relay adapter 30A has its own individual ID set to “A” and the individual ID of the relay partner set to “B”. . In addition, the relay adapter 30B has its own individual ID set as “B” and the individual ID of the relay partner as “A”.

  Here, a case where two relay adapters 30 are paired will be described, but the present invention is not limited to this. For example, a plurality of individual IDs of relay partners may be set, and the interlocking inspection signal may be relayed by one-to-many or many-to-many relay adapters 30.

Furthermore, the storage unit 21 stores information on a group ID and a self-address acquired when joining the alarm device group.
The group ID is an ID unique to each alarm device group, and identifies the alarm device group to which the group belongs.
The self address is set uniquely for each fire alarm and relay adapter 30 in the alarm group, and is used for communication within the alarm group to which the self belongs.

(Grouping process)
Next, the grouping process of the relay adapter 30 will be described.
As shown in FIG. 8, the case where the relay adapter 30 joins the alarm device group A composed of the parent device 10 and the child device 20 will be described as an example.

  The relay adapter 30 transmits a registration request signal by the transmission / reception circuit 15 when the power is turned on. When receiving the registration request signal from relay adapter 30, base unit 10 transmits a response signal to relay adapter 30. The response signal includes at least information on the group ID and the self-address assigned to the relay adapter 30.

  When the relay adapter 30 receives the response signal from the parent device 10, the relay adapter 30 stores the group ID and the assigned self address information in the storage unit 21. Then, a group joining notification for notifying the parent device 10 of joining the alarm device group A is transmitted.

When the base unit 10 receives the group join notification, the base unit 10 registers the relay adapter 30 as a slave unit of the alarm group A. That is, in the subsequent communication, the parent device 10 communicates with the relay adapter 30 as a child device in the alarm device group A.
The base unit 10 stores information on the address of the relay adapter 30 in the storage unit 21 and transmits a group join notification including information on the address of the relay adapter 30 to the other handset 20. The other slave unit 20 receives the group join notification from the master unit 10 and stores the address information of the relay adapter 30 in the storage unit 21.
In the above example, the relay adapter 30 receives the group ID and the self-address by communication from the base unit 10 and stores them in the storage unit 21. However, the relay adapter 30 does not perform communication or the like in advance in the storage unit 21. The structure to store may be sufficient. The same applies to the point that the parent device 10 and the other child devices 20 store the address information of the relay adapter 30 in the storage unit 21.

  When the relay adapter 30 performs a grouping process in an environment where there are a plurality of existing groups, there is a possibility that response signals from a plurality of master units may be received if the relay adapter 30 transmits a registration request signal. In this case, for example, only the response signal of the parent device that has received the response signal first is processed and joined to the group of the parent device. Further, for example, only a response signal having a large electric field strength is processed and joined to the parent group.

(Linked inspection operation)
Next, the operation of the linked inspection will be described.
9 and 10 are diagrams for explaining the operation of interlocking inspection of the alarm system according to Embodiment 2 of the present invention.
FIG. 11 is a diagram showing the contents of the interlocking inspection signal according to Embodiment 2 of the present invention.
In FIG. 9 and FIG. 10, a suffix number corresponding to the self address is attached to the reference numeral in order to distinguish each slave unit 20.

  First, in FIG. 9, the interlock inspection operation when the interlock inspection switch 22 of the slave unit 20-1 of the alarm device group A is turned on will be described.

When the interlock check switch 22 is turned on by the user, the slave unit 20-1 of the alarm device group A simulates the detection of fire, and an alarm (indicating that the fire alarm device has detected a fire by voice or indicator light) (Hereinafter referred to as “fire alarm”). For example, a sound such as “It is a fire. It is a fire” is sounded and a red light is blinked. The ringing or display by this fire alarm is automatically stopped after a predetermined time.
Moreover, the subunit | mobile_unit 20-1 of the alarm device group A transmits the interlocking inspection signal 100 while performing alarm operation | movement itself. The interlock inspection signal 100 will be described with reference to FIG.

  As shown in FIG. 11A, the interlock inspection signal 100 for performing the interlock operation in the alarm device group includes at least a group ID 101, a fire source AD (address) 102, a partner AD 103, and status information 104. Yes.

  The group ID 101 is set to an ID inherent to the alarm device group. Here, since the subunit | mobile_unit 20-1 belongs to the alarm device group A, "group A" is set.

  The fire source AD 102 is set with the self-address of the fire alarm that detects the fire. Here, “address 1”, which is the self address of the slave 20-1, is set.

The partner AD 103 sets the self-address of the fire alarm and the relay adapter 30 that perform the linked inspection. Here, since all the fire alarms in the alarm device group A and the relay adapter 30 perform the linked inspection, “all addresses” for designating all the self-addresses assigned in the alarm device group A are set.
As described above, since the self-address of relay adapter 30 is set as one of the addresses of the slave units in the alarm device group, it is necessary to distinguish between the fire alarm device and relay adapter 30 in partner AD 103. Absent.

  In the status information 104, information indicating the content of the radio signal is set. Since this is a linked inspection that simulates fire detection, it is set to “linked inspection”.

Next, when the master unit 10, the slave unit 20-2, and the slave unit 20-3 of the alarm device group A receive the interlocking inspection signal 100, the group ID 101 matches the own alarm device group, and the partner AD 103 It is determined whether or not a self address is included.
When the group IDs 101 match and the other party AD 103 includes a self address, an alarm (hereinafter referred to as “linked alarm”) linked to the fire source alarm is performed by voice or an indicator lamp. For example, a sound such as “It is a fire in another place” is sounded and an orange light is turned on. In addition, it is determined from the status information 104 that it is “linked inspection”, and the linked inspection is automatically stopped after a predetermined time has elapsed.
On the other hand, when the group ID 101 or the partner AD 103 does not match, the received interlocking inspection signal 100 is discarded.

Furthermore, when the base unit 10 receives the interlocking inspection signal 100, the base unit 10 retransmits the interlocking inspection signal 100 having the same content as the received interlocking inspection signal 100.
Thereby, the interlock inspection signal 100 is received by all the fire alarms and the relay adapter 30 in the alarm device group.
For example, as shown in FIG. 9, even when the slave unit 20-1 and the relay adapter 30 </ b> A cannot directly perform wireless communication, the relay adapter 30 </ b> A can receive the interlocking inspection signal 100 transmitted from the master unit 10. It becomes possible.

Next, the operation of the relay adapter 30 will be described.
FIG. 12 is a flowchart for explaining an operation for interlocking inspection of the relay adapter 30 according to the second embodiment of the present invention.
Hereinafter, based on each step of FIG. 12, it demonstrates, referring FIGS. 9-11.

(S201)
When the link inspection signal 100 is received by the transmission / reception circuit 15, the control circuit 11 of the relay adapter 30 compares the information of the group ID 101 with the information of the group ID stored in the storage unit 21, and links the same group. It is determined whether it is an inspection signal.
When the interlock inspection signal of the same group has not been received, the process proceeds to step S206.

(S202)
On the other hand, when receiving the interlock inspection signal of the same group, the control circuit 11 determines the output setting of the fire alarm sound output setting switch 23.
If the fire alarm sound output setting switch 23 is in the OFF state, that is, if it is set not to perform an acoustic alarm, the process proceeds to step S204.

(S203)
On the other hand, when the fire alarm sound output setting switch 23 is in the ON state, that is, when the setting is to perform an acoustic alarm, the control circuit 11 uses the alarm sound control circuit 18 to ring in conjunction with the fire source alarm (hereinafter referred to as “linked ringing”). .) For example, a sound such as “It is a fire in another place” is sounded.

(S204)
Next, the control circuit 11 causes the indicator lamp circuit 19 to perform a display linked to the fire source alarm (hereinafter referred to as “linked display”). For example, an orange lamp is turned on. The ringing or display by this interlocking alarm is automatically stopped after a predetermined time.

(S205)
Next, the control circuit 11 causes the transmission / reception circuit 15 to transmit the interlocking inspection signal 200. The interlock inspection signal 200 will be described with reference to FIG.

  As shown in FIG. 11B, the interlock inspection signal 200 for performing the interlock operation between the relay adapters 30 includes at least the relay partner individual ID 201, the transmission source AD 202, the partner AD 203, and the status information 204. .

  The individual ID 201 of the relay partner is set to the individual ID of the relay partner preset in the storage unit 21. Here, “individual ID (B)”, which is the individual ID of relay adapter B as the relay partner, is set.

  The transmission source AD 202 is set with its own individual ID of the relay adapter 30 that transmits the interlock inspection signal 200. Here, “individual ID (A)” which is the individual ID of relay adapter 30A is set.

In the partner AD 203, the individual ID of the relay partner is set. Here, “individual ID (B)”, which is the individual ID of relay adapter B as the relay partner, is set.
The partner AD 203 can be omitted. In the present embodiment, the partner AD 203 is provided in order to make the format of the interlock inspection signal in the alarm device group and the interlock inspection signal between the relay adapters 30 common.

  In the status information 204, information indicating the contents of the wireless signal is set. Since this is a linked inspection that simulates fire detection, it is set to “linked inspection”.

  After transmitting the interlocking inspection signal 200, the control circuit 11 returns to step S201 and repeats the above operation.

The interlocking inspection signal 200 transmitted from the relay adapter 30 is received by the relay adapter 30 belonging to another alarm device group.
And the control circuit 11 of the relay adapter 30 which received the interlocking inspection signal 200 determines whether the interlocking inspection signal 200 is an interlocking inspection signal of the same group by said step S201.
For example, when the relay adapter 30B receives the interlock inspection signal 200 from the relay adapter 30A, the group ID stored in the storage unit 21 does not match the individual ID 201 of the relay partner in step S201, and the interlock inspection of the same group is performed. If it is not a signal, the process proceeds to step S206.

(S206)
The control circuit 11 of the relay adapter 30 compares the information of the individual ID 201 of the relay partner of the received interlocking inspection signal 200 with the information of its own individual ID stored in the storage unit 21, and sends it to its own individual ID. It is determined whether or not this is a linked inspection signal.
When the interlocking inspection signal addressed to its own individual ID has not been received, the process proceeds to step S211.

(S207)
On the other hand, when receiving the interlock inspection signal addressed to its own individual ID, the control circuit 11 determines the output setting of the fire alarm sound output setting switch 23.
If the fire alarm sound output setting switch 23 is in the OFF state, that is, if it is set not to perform an acoustic alarm, the process proceeds to step S209.

(S208)
On the other hand, when the fire alarm sound output setting switch 23 is in the ON state, that is, when setting to perform an acoustic alarm, the control circuit 11 causes the alarm sound control circuit 18 to make a sound as a fire source alarm (fire source sound). . For example, it sounds like “fire.

(S209)
Next, the control circuit 11 causes the indicator lamp circuit 19 to display a fire source alarm (fire source display). For example, a red light is blinked. The ringing or display by this fire alarm is automatically stopped after a predetermined time.

In this way, the relay adapter 30 that has received the interlocking inspection signal 200 from another alarm device group operates as a fire alarm device of the fire source in the alarm device group to which the relay adapter 30 belongs.
For example, as shown in FIG. 9, when the relay adapter 30B receives the interlock inspection signal 200 from the relay adapter 30A, in the alarm device group B, the relay adapter 30B operates as a fire alarm device that detects a fire. .
Thus, when the relay adapter 30 performs the fire source alarm, it is possible to identify the alarm transmission source in the alarm group even if it is a linked operation from another alarm group.

In the present embodiment, a case has been described in which the relay adapter 30 that has received the interlocking inspection signal 200 from another alarm device group performs a fire source alarm, but the present invention is not limited to this.
For example, the relay adapter 30 that has received the interlocking inspection signal 200 from another alarm device group performs interlocking inspection, and performs interlocking sounding and interlocking display by the same operation as in steps S203 and S204. good.
Thus, it is possible to specify that the alarm source is not in the alarm device group by the relay adapter 30 performing the linked inspection.

(S210)
Next, the control circuit 11 causes the transmission / reception circuit 15 to transmit the interlocking inspection signal 300. The interlock inspection signal 300 will be described with reference to FIG.

  As shown in FIG. 11C, the interlock inspection signal 300 for performing the interlock operation from the relay adapter 30 includes at least a group ID 301, a fire source AD 302, a counterpart AD 303, and status information 304.

  In the group ID 301, information on the group ID to which the relay adapter 30 belongs is set. Here, since the relay adapter 30B belongs to the alarm device group B, “group B” is set.

The fire source AD302 is set with the self-address of the fire alarm that detects the fire.
In the alarm device group B, “4” is assigned to the relay adapter 30B as the address in the group. Therefore, “address 4”, which is the self-address of relay adapter 30B, is set here.
As described above, since the self-address of relay adapter 30B is set as one of the addresses of the slave units in the alarm device group, it is necessary to distinguish between the fire alarm device and relay adapter 30 in fire source AD302. Absent.

  The partner AD 303 sets the self-address of the fire alarm that performs the linked inspection. Here, since all the fire alarms in the alarm device group B perform the linked inspection, “all addresses” for designating all the self addresses assigned in the alarm device group B are set.

  In the status information 304, information indicating the contents of the radio signal is set. Since this is a linked inspection when a fire is detected, “linked inspection” is set.

  After transmitting the interlocking inspection signal 300, the control circuit 11 returns to step S201 and repeats the above operation.

Next, when the parent device 10, the child device 20-1, the child device 20-2, and the child device 20-3 of the alarm device group B receive the interlock inspection signal 300, the group ID 301 matches the own alarm device group. In addition, it is determined whether or not the partner AD 303 includes a self address.
When the group IDs 301 match and the self-address is included in the partner AD 303, the linked inspection is performed by voice or an indicator lamp. For example, a sound such as “It is a fire in another place” is sounded and an orange light is turned on. The ringing or display by this interlocking alarm is automatically stopped after a predetermined time.
On the other hand, when the group ID 301 or the partner AD 303 does not match, the received interlocking inspection signal 300 is discarded.

Furthermore, when the base unit 10 receives the interlocking inspection signal 300, the base unit 10 retransmits the interlocking inspection signal 300 having the same contents as the received interlocking inspection signal 300.
Thereby, the interlock inspection signal 300 is received by all the fire alarms in the alarm group.
For example, as illustrated in FIG. 9, even when the relay adapter 30 </ b> B and the slave unit 20-2 cannot directly wirelessly communicate, the slave unit 20-2 receives the interlocked inspection signal 300 transmitted from the master unit 10. It becomes possible.

  In this way, the master unit 10 or the slave unit 20 that is a fire alarm is linked to other fire alarms and relay adapters 30 to which the alarm group belongs, when the linked inspection switch 22 is turned on. Send an inspection signal. Further, when an interlock inspection signal transmitted from another fire alarm device or relay adapter 30 to which the alarm device group belongs is received, an interlock alarm is performed.

(S211)
If it is determined in step S206 that the interlock inspection signal addressed to the individual ID is not received, the control circuit 11 of the relay adapter 30 determines whether or not the interlock inspection switch 22 of the relay adapter 30 is turned on.
If the self-linked inspection switch 22 is not on, the process returns to step S201 and the above operation is repeated.
On the other hand, if the self-linked inspection switch 22 is on, the process proceeds to step S207, where a fire source alarm is issued and the linked inspection signal 300 is transmitted to the same alarm device group as in steps S207 to S210 described above.

Thus, the relay adapter 30 transmits a linked inspection signal to each fire alarm in the alarm group to which the relay adapter 30 is turned on when the linked adapter switch 22 is turned on.
For example, as shown in FIG. 10, when the interlock inspection switch 22 of the relay adapter 30 </ b> A of the alarm device group A is turned on, the interlock inspection signal 300 in which “Group A” is set in the group ID 301 is transmitted to the parent device in the alarm device group A. Only the fire alarm device in alarm device group A performs an interlocking alarm.

  The “fire alarm” and the “linked alarm” in the present embodiment correspond to the “fire alarm” in the present invention.

As described above, in the present embodiment, each of the plurality of alarm device groups has the relay adapter 30, and the fire alarm device is assigned to the alarm device group to which the self alarm device group belongs when the self-inspection inspection switch 22 is turned on. A linked inspection signal is transmitted to other fire alarms and the relay adapter 30, and a fire alarm is issued when a linked inspection signal transmitted from another fire alarm unit or relay adapter 30 to which the alarm group belongs is received. . The relay adapter 30 also transmits a linked check signal to each fire alarm of the alarm group to which the relay adapter 30 belongs when the linked check switch 22 of the relay adapter 30 is turned on, and the fire alarm of the alarm group to which the relay adapter 30 belongs. When the interlocked inspection signal transmitted from is received, the interlocked inspection signal is transmitted to the relay adapter 30 of the other alarm device group, and the interlocked inspection signal transmitted from the relay adapter 30 of the other alarm device group is received. At the same time, an interlocking inspection signal is transmitted to the fire alarm of the alarm group to which it belongs.
For this reason, even when there are a plurality of alarm device groups, the linked inspection can be performed for other alarm device groups in conjunction with the linked inspection of any one of the alarm device groups.
Further, by turning on the interlock inspection switch 22 of the relay adapter 30, the interlock inspection can be performed only for the fire alarm device in the desired alarm device group.

In addition, the fire alarm that performs linked inspection can be extended to other alarm groups. Therefore, even if it is a case where the installation range which can perform alarm operation in conjunction with alarm devices is expanded, interlock inspection can be performed.
Further, even when the maximum number that can be joined to the alarm device group is set, the linked inspection by the alarm devices exceeding the maximum number can be performed. Therefore, the number of alarm devices that perform linked inspection can be expanded.
Therefore, the range (area) for performing the linked inspection can be expanded. For example, even in a residence where there are many rooms where it is necessary to install a fire alarm beyond the maximum number of alarm devices, the fire alarm can be inspected throughout the residence.
It can also be used in a residence where radio waves may not reach, such as a remote building or a two-family house.
Moreover, since the relay adapter 30 is provided for each alarm device group, the communication distance can be increased.

In addition, among the plurality of fire alarms, each fire alarm in the alarm group to which the self belongs and a fire alarm capable of wireless communication with the relay adapter 30 operate as the master unit 10, and the other fire alarms are slave units. It operates as 20. When the master unit 10 receives the interlock check signal from the slave unit 20 or relay adapter 30 of the alarm device group to which the master unit 10 belongs, the master unit 10 performs the interlock check on the slave unit 20 and relay adapter 30 of the alarm group to which the master unit 10 belongs. Send a signal.
For this reason, for example, even if the slave unit 20 in the alarm device group and the relay adapter 30 cannot directly wirelessly communicate, the interlock inspection signal from the slave unit 20 can be transmitted to the relay adapter 30.

In addition, the relay adapter 30 includes a fire alarm sound output setting switch 23 that sets whether or not to perform an acoustic alarm when receiving a linked inspection signal.
For this reason, whether or not an acoustic alarm can be set can be set by a user setting.
