  Generally, in an alarm system capable of wireless communication between a master unit and each of a plurality of slave units, when an alarm unit provided in one of the plurality of slave units detects an alarm state, the alarm unit Issues a warning, and the slave unit transmits a slave unit side alarm code in which identification information of the slave unit itself is added to alarm information such as an alarm signal. The master unit that has received the slave unit side alarm code is a slave unit that collates the slave unit identification information contained in the slave unit side alarm code with the identification information of the plurality of slave units of the master unit and is associated with itself. If it is determined, it is received as alarm information from the slave unit, and an alarm is issued from an alarm device provided in itself. Further, the parent device transmits a parent device side alarm code in which the parent device identification information is added to the alarm information to other child devices. When each of the other slave units that have received the master unit side code collates the master unit identification information included in the code with the master unit identification information of the slave unit, and determines that the master unit is an affiliated master unit Receives the alarm information from the parent machine and issues an alarm from each alarm device provided. Such an alarm system is a normal technique performed by a person skilled in the art, and no prior art document is shown.

  However, in the conventional alarm system, when an alarm provided in the slave unit detects an alarm state, the information is transmitted to another slave unit via the master unit. For this reason, when the master unit breaks down, the alarm information is not transmitted to other slave units, the alarm device provided in them does not issue an alarm, and there is a possibility that the transmission of the alarm information to the user may be delayed. there were.

  An object of the present invention is to provide an alarm system capable of interlocking an alarm device provided in one slave unit and an alarm device provided in each of the other slave units even when the master unit fails. The point is to provide.

  The first characteristic configuration of the alarm system of the present invention is that wireless communication is possible between the parent device and each of the plurality of child devices, and an alarm device provided in one child device of the plurality of child devices is provided. When an alarm state is detected, the alarm device issues an alarm, and the one slave unit transmits a slave unit side alarm code, and the master unit that receives the slave unit side alarm code receives the master unit side alarm code. An alarm system that issues an alarm by an alarm device provided in each of the other slave units except the one slave unit that has transmitted and received the master unit side alarm code, wherein each of the other slave units is When a slave unit side alarm code transmitted from one slave unit is made recognizable and each of the other slave units recognizes a failure of the master unit, an alarm provided to the one slave unit When the device detects an alarm state and the one slave unit transmits the slave unit side alarm code, Serial least one child device of another slave unit receives the child machine side alarm code, slave machine side alarm code alarm device provided in each of the received slave machine is in the point where the issued warning.

  According to this configuration, each slave unit can recognize the slave unit side alarm code transmitted by the other slave units, and the alarm unit provided in one slave unit detects the alarm state and detects one slave unit. When a machine transmits a slave unit side alarm code, when at least one of the other slave units recognizes the failure of the master unit, the slave unit can receive the transmitted slave unit side alarm code Therefore, the alarm device provided in one slave device that has detected the alarm state can be linked to the alarm device provided in another slave device without using the master device.

  The second characteristic configuration of the alarm system of the present invention is that each of the slave units that have received the slave unit side alarm code receives the slave unit side alarm code or the slave unit side alarm code of the slave unit that has received the slave unit side alarm code. It is in the point to transmit.

  According to this configuration, even if there is a slave unit that is far from one slave unit that has detected an alarm state and has not directly received the slave unit side alarm code transmitted from the slave unit, the intermediate distance Another cordless handset located in can relay the alarm code.

[First Embodiment]
Hereinafter, an alarm system according to the present invention will be described.
As shown in FIGS. 1 to 4, the alarm system includes a wireless master device A (an example of a parent device) and a plurality of wireless slave devices a (an example of a slave device). The wireless slave device a is configured to be capable of wireless communication. Each of the wireless master device A and the plurality of wireless slave devices a is provided with a fire alarm device 1 (an example of an alarm device). Such an alarm system is provided in a house, for example, and the wireless master device A and the plurality of wireless slave devices a are installed in each room (not shown) of the house. The installation location of the wireless master device A and the plurality of wireless slave devices a may be any room in an apartment, each floor of an office, or the like, and is not particularly limited.

  In the alarm system according to the present embodiment, the case where three wireless slave units a are provided is illustrated, but the present invention is not limited to this, and it is naturally possible to appropriately increase or decrease depending on the installation location such as the number of rooms. . Moreover, although the case where the fire alarm device 1 is provided as a separate body is illustrated for each of the wireless master device A and the wireless slave device a, the fire alarm device 1 is integrated with the wireless master device A and the wireless slave device a. There is no problem even if it is provided. As the fire alarm 1, various fire alarms such as smoke detection type and heat detection type can be used. An alarm can naturally be employed.

  Hereinafter, the device configuration of the alarm system according to the present embodiment will be described. Since the device configuration of the wireless slave device a is the same as that of the wireless master device A, only the device configuration of the wireless master device A will be described. The description of the device configuration a is omitted.

  As shown in FIG. 4, the wireless master device A includes an LSI 11 as a core member, and a fire alarm device 1 that detects the occurrence of a fire and a fire alarm device other than the fire alarm device 1 that detects the occurrence of a fire. Various processes such as an interlocking alarm process for linking 1 with each other and an edge process for linking the wireless master device A and each of the plurality of wireless slave devices a are performed.

  The LSI 11 is provided with an edge switch 12, an antenna 13, and a nonvolatile memory 14, and further, although not shown, a high-frequency circuit unit, a post-modulation processing circuit unit, a microcomputer unit, and the like are provided. The edge switch 12 is an example of an operation unit when performing the edge work between the wireless parent device A and the wireless child device a. For example, the edge switch 12 of the wireless parent device A and the wireless child device a is connected to the edge switch 12. By pressing simultaneously, it is possible to communicate with each other. As the antenna 13, a conventionally known antenna can be appropriately selected according to the type, distance, and the like of the radio wave between the wireless master device A and the wireless slave device a. Examples of the non-volatile memory 14 include ROM such as mask ROM, PROM, EPROM, and EEPROM, flash memory, and the like. The non-volatile memory 14 of the wireless master device A and the wireless slave devices a1 to a3 registers the ID of the wireless master device A (an example of identification information) and all the IDs of the wireless slave devices a1 to a3 (an example of identification information). Has been. In this way, by sharing the so-called relationship information, that is, the ID of the wireless master device A and all the IDs of the wireless slave devices a1 to a3, between the wireless master device A and the wireless slave devices a1 to a3, Machines a can also recognize each other.

  In such an alarm system, as shown in FIG. 1, when the fire alarm 1 provided in one of the plurality of wireless slave devices a1 to a3, for example, the wireless slave device a1, detects the occurrence of a fire, The fire alarm device 1 turns on the LED 5 and emits an alarm sound by the buzzer 4 and outputs a fire abnormality signal from the fire alarm device 1 to the wireless slave device a1 through the interface circuit 8. The wireless slave device a1 to which the fire abnormality signal is input transmits a slave unit side alarm code in which the ID of the wireless slave device a1 itself is added to the fire abnormality signal. The wireless master device A that has received the cordless handset side alarm code collates the ID included in the cordless handset side alert code with the matching information that the cordless handset has, and determines whether or not the cordless handset has been transmitted from the matching cordless handset. to decide. If it is determined that the signal is transmitted from the associated wireless slave device a1, the wireless master device A outputs a fire abnormality signal to the fire alarm device 1 provided in the wireless master device A via the interface circuit 8. As a broadcast signal for all the wireless slave devices a1 to a3, the wireless slave device a1 of the fire alarm device 1 that has detected the occurrence of a fire is detected as a fire abnormality signal. Send the parent machine side alarm code with ID added. The wireless slave devices a2 and a3 that have received the parent device side alarm code collate the ID included in the parent device side alarm code with the ID of the wireless device A, and are determined to be from the associated wireless parent device A. For example, the fire abnormality signal is output to the fire alarm device 1 provided through the interface circuit 8 as if the wireless slave devices a2 and a3 are directed to the wireless slave devices a2 and a3, and the alarm operation is performed. In addition, as a main | base station side alarm code, for example, ID of the radio | wireless main unit A itself may only be added to a fire abnormal signal, and it is not specifically limited.

  In the alarm system according to the present embodiment, in a normal state, for example, the wireless master device A transmits a confirmation request code to all the slave devices every predetermined time such as 48 hours and receives the confirmation request code. Each wireless slave device a1 to a3 transmits a confirmation code, and the wireless master device A receives the confirmation code, so that the wireless slave device A and the wireless slave device a are operating normally. Have confirmed. When the wireless master device A does not receive a confirmation code from any of the wireless slave devices a even after a predetermined time has passed with respect to the transmitted confirmation request code, the wireless slave device a corresponding to the confirmation code that is not received Recognize that it is out of order, and notify the user by operating the buzzer 4, LED 5, etc. On the other hand, if the wireless slave device a does not receive the confirmation request code even after a predetermined time has elapsed from the scheduled time when the wireless master device A transmits the confirmation request code, the wireless slave device A recognizes that the wireless master device A is out of order. Then, the user is notified by operating the buzzer 4 and the LED 5. When the wireless slave device a recognizes that the wireless master device A is out of order, the wireless slave device a enters the temporary interlocking alarm processing mode, and other wireless devices a based on the association information registered in its own nonvolatile memory 14. The slave unit side alarm code from the slave unit a can be received.

  In the temporary interlock alarm processing mode, as shown in FIG. 2, when the fire alarm 1 provided in one of the plurality of wireless slave devices a1 to a3, for example, the wireless slave device a1, detects the occurrence of a fire. As in the normal state of the wireless master device A, the fire alarm device 1 turns on the LED 5, emits an alarm sound by the buzzer 4, and the wireless slave device a1 adds the ID of the wireless slave device a1 itself to the fire abnormality signal. Send the machine side alarm code. The wireless slave devices a2 and a3 that have received the cordless handset side alarm code collate the ID included in the cordless handset side alert code with the matching information that the cordless handset has and send from the cordless handset a1 that is linked to the same wireless master device A. It is judged whether it is what was done. When it is determined that the call is transmitted from the wireless slave device a1 associated with the same wireless master device A, the fire alarm device 1 is activated. Thereby, even when the wireless master device A is out of order, the fire alarm device 1 in which the occurrence of a fire is detected can be linked to another fire alarm device 1.

In addition, in the temporary linked alarm processing mode of the alarm system according to the present embodiment, the installation location of the wireless slave device a1 of the fire alarm that detects the occurrence of a fire and the installation location of another wireless slave device, for example, the wireless slave device a3 If the distance from the wireless slave unit a1 is far, the radio signal of the slave side alarm code from the wireless slave unit a1 may not reach the wireless slave unit a3, and the fire alarm device 1 may not be linked. Even in this case, a wireless slave installed at a distance where the radio wave of the cordless handset side alarm code can reach, for example, the fire alarm 1 of the radio cordless handset a2 is interlocked, and in a place where radio waves of the cordless handset side alarm code cannot reach There is no problem even if the fire alarm 1 is not linked because it is far enough from the fire occurrence site, but the wireless slave device a2 that has received the slave side alarm code from the wireless slave device a1 is further connected to the wireless slave device. You may make it transmit the subunit | mobile_unit side alarm code which added the ID of the radio | wireless subunit | mobile_unit a2 itself to a fire abnormal signal by transferring the subunit | mobile_unit side alarm code of a1. Thereby, a fire abnormal signal is transmitted also to the wireless slave device a3 installed at a distance where the radio wave from the wireless slave device a1 does not reach directly, and the fire alarm device 1 can be interlocked.
When the number of wireless slave devices a is large and the area where the wireless slave devices a of the alarm system are installed is wide, the wireless slave device a3 and other wireless slave devices a can also transmit a fire abnormality signal. .

  In the alarm system according to the present embodiment, as a method of associating the wireless master device A and the wireless slave devices a1 to a3, for example, first, the wireless master device a1 is brought close to the wireless master device A1, and the wireless master device Both A and the remote switch 12 provided in the wireless slave unit a are both pressed to enable communication, and the mutual IDs are registered in the respective nonvolatile memories 14. Subsequently, by performing the same operation on each of the wireless slave devices a2 and a3, the nonvolatile memory 14 of each of the wireless slave devices a1 to a3 is stored in the wireless master device 14 as shown in FIG. The ID of A is registered, and the IDs of the wireless slave devices a1 to a3 are registered in the nonvolatile memory 14 of the wireless master device A. After that, the timing of completion of all framing work and the timing of completion of installation (for example, after waiting for a predetermined time, such as 2 hours), from the wireless master device A, the IDs of the wireless slave devices a1 to a3 that are connected , A marriage information transmission code including the ID of the wireless master device A itself is transmitted. If this cordless handset a1-a3 receives this code and registers it in the respective nonvolatile memory 14, it becomes possible to share the marriage information between the wireless master device A and the wireless slave devices a1-a3. .

  The edge work is not limited to this method, and any conventionally known edge method can be adopted as long as it is a method of exchanging IDs with each other, regardless of wireless or wired. In addition, all information registered in the nonvolatile memory 14 can be registered in the nonvolatile memories 14 at the time of the matching work. That is, for example, in the case where the wireless master device A3 and the wireless slave device a3 that have been paired with the wireless slave devices a1 and a2 are paired, the non-volatile memory 14 of the wireless slave device a3 stores the ID of the wireless master device A. In addition, the IDs of the wireless slave devices a1 and a2 that are already registered in the nonvolatile memory 14 of the wireless master device A can be registered. In the alarm system according to the present embodiment, the case where ID is used as the identification information in the present invention is exemplified. However, as long as the information can identify each of the wireless master device A and the wireless slave device a, there is no particular limitation. For example, position information indicating the installation location of the wireless master device A and the wireless slave device a may be used.

  Other configurations of the alarm system and other processes such as an alarm stop operation are the same as those of a conventionally known alarm system.

[Second Embodiment]
In the present embodiment, when the wireless slave device a does not recognize the failure of the wireless master device A in a state where the wireless master device A has failed, the fire alarm device 1 of the wireless slave device a detects the occurrence of a fire. Processing when detected will be described. For example, even if the wireless master device A is out of order, the wireless slave device a cannot recognize the failure of the wireless master device A if the scheduled time before the wireless master device A transmits the confirmation request code has elapsed. In such a state, as shown in FIG. 3, when one of the plurality of wireless slave devices a1 to a3, for example, the fire alarm 1 of the wireless slave device a1, detects the occurrence of a fire, the wireless master device A As in normal operation, the fire alarm device 1 turns on the LED 5, emits an alarm sound by the buzzer 4, and the wireless slave device a1 adds a slave alarm code that adds the ID of the wireless slave device a1 to the fire abnormality signal. send. At this time, if the wireless master unit A is normal, the wireless master unit A that has received the slave unit side alarm code transmits an Ack signal, and the wireless slave unit a1 that has transmitted the slave unit side alarm code receives the Ack signal. Thus, it is confirmed that the wireless master device A has normally received the slave device side alarm code. However, the wireless master device A is out of order, and the wireless slave device a1 recognizes the failure of the wireless master device A because it does not receive the Ack signal even after a predetermined time has elapsed after issuing the slave device side alarm code. A fire abnormality signal is transmitted to another wireless slave device a again. Specifically, the wireless slave device a1 is a pseudo master device side in which the ID of the wireless slave device a1 itself and the ID of the wireless master device A are added to the fire abnormality signal as a broadcast signal for the other wireless slave devices a2 and a3. Send an alarm code. The wireless slave devices a2 and a3 that have received the pseudo master device side alarm code recognize the fire alarm signal from the wireless master device A associated with the ID included in the pseudo master device side alarm code, and warn the fire alarm device 1 Make it work. In addition, as a pseudo | simulation main | base_unit side alarm code, for example, ID of the radio | wireless main | base station A may only be added to a fire abnormal signal, and it is not specifically limited. As a result, even if the wireless slave device a1 has not recognized the failure of the wireless master device A from the beginning, the wireless slave device a1 can communicate by transmitting a broadcast signal instead of the wireless master device A. It is possible to link the fire alarm device 1 in which the occurrence of fire is detected with another fire alarm device 1. In the present embodiment, the case where the wireless slave device a1 recognizes the failure of the wireless master device A when the Ack signal is not received even after a lapse of a predetermined time after issuing the slave device side alarm code is illustrated. However, the present invention is not limited to this case. For example, when the wireless slave device a1 does not receive a broadcast signal from the wireless master device A even after a predetermined time has elapsed after transmitting the slave device side alarm code. A failure of the wireless master device A may be recognized.

  Even in this case, for example, if the pseudo master unit alarm code includes information on the failure of the radio master unit A, the radio slave unit a2 that has received the pseudo master unit side alarm code from the radio slave unit a1. However, the fire alarm signal is also transmitted to the wireless slave device a installed at a distance where the radio wave from the wireless slave device a1 does not reach directly by transmitting the alarm code on the side of the pseudo master device. The device 1 can be interlocked. Further, in the processing of the present embodiment, each wireless slave device a only needs to recognize the ID of the wireless master device A in addition to its own ID, so each nonvolatile memory 14 of the wireless slave device a includes It is not always necessary to register the ID of the other wireless slave device a. It is sufficient to register only the ID of the wireless master device A.

  In the alarm system according to the present invention, a system that performs only the processing of the first embodiment, a system that performs only the processing of the second embodiment, and the first embodiment in a state where the parent device is out of order. Any system that combines the above process and the process of the second embodiment can be employed. Furthermore, conventionally known processes can be combined.

  The present invention is capable of wireless communication between a parent device and each of a plurality of child devices, and when an alarm device provided in one of the plurality of child devices detects an alarm state, the alarm device When an alarm is issued, one slave unit transmits a slave unit side alarm code, and a master unit that receives the slave unit side alarm code transmits a master unit side alarm code and receives one master unit side alarm code. The present invention can be applied to various alarm systems in which an alarm device provided in each of the other handset devices other than the handset device issues an alarm.
