Description

  In the present invention, the master unit has identification information of a plurality of slave units, each of the plurality of slave units has identification information of the master unit, and the master unit and each of the plurality of slave units are The present invention relates to a wireless system capable of performing wireless communication, and an edge method in the wireless system.

  In general, in a wireless system in which wireless communication is possible between a parent device and each of a plurality of child devices, the parent device has identification information of each child device, and each child device has identification information of the parent device. When the slave unit communicates with the master unit, the slave unit transmits a code in which identification information of the slave unit itself is added to information to be sent to the master unit such as an alarm signal. The parent device that has received the code identifies the child device by comparing the identification information of the child device included in the code with the identification information of the plurality of child devices included in the parent device, and as information from the identified child device receive. On the other hand, when the parent device communicates with the child device, the parent device transmits a code in which identification information of the parent device is added to information to be sent to the child device. Each of the plurality of slave units that have received the code collates the identification information of the master unit included in the code with the identification information of the master unit included in the slave unit. Receive as information. In addition, when the master unit sends information to a specific slave unit, the master unit adds a code that includes the information to be sent to the slave unit and the identification information of the master unit plus the identification information of the destination slave unit. send. The slave unit that has received the code collates the identification information of the specific slave unit included in the code with its own identification information in addition to the identification information of the master unit. Judge that the information is from.

In this type of wireless system, in order to enable wireless communication between the parent device and each of the plurality of child devices, the identification information of each child device is registered in advance in the parent device, and each child device is registered. A so-called associating operation for registering the identification information of the parent device is required. In general, such a matching operation is performed by causing each parent device to communicate with each other one by one wirelessly or by wire, and exchange identification information with each other. When the matching operation between the master unit and all the slave units is completed, the master unit has the identification information of all the slave units, and all the slave units have the identification information of the master unit. In addition, when a new child device is added or when a child device is replaced with a new child device due to a failure or the like, the new child device can be added to the existing wireless system by being associated with the parent device.
Note that the technology for performing wireless communication between the parent device and each of the plurality of child devices is a normal technology performed by those skilled in the art, and prior art documents and the like are not shown.

  However, in the conventional wireless system, when the master unit needs to be replaced with another new master unit due to a failure or the like, the new master unit has to redo all the slave units one by one. For this reason, it was very time-consuming to change the base unit. It takes more time depending on the number of slave units and the location of the slave units. In addition, if the handset is installed in a highly private space such as a bedroom in a house where a wireless system is provided, the worker will enter such a space when performing the matching work. There was an inconvenience.

  An object of the present invention is to provide a wireless system that can be easily operated even when the base unit is replaced, and an edge method in the wireless system.

  The wireless system of the present invention is characterized in that a master unit has identification information of a plurality of slave units, each of the plurality of slave units has identification information of the master unit, and the master unit and the plurality of slave units A wireless system capable of wireless communication with each of the devices, wherein at least one of the plurality of slave devices has identification information of the plurality of slave devices.

  Further, the characteristic means of the edge method of the present invention is an edge method in the wireless system, and when the parent device is exchanged with another parent device, identification information of the different parent device and the plurality of child devices And the other parent device has identification information of the plurality of child devices.

According to the present invention, when replacing a parent device with another parent device due to a failure or the like, a child device having identification information of another parent device and a plurality of child devices, regardless of the number of child devices performing wireless communication As a result, the other parent device can have the identification information of all the child devices to be wirelessly communicated. For this reason, it is not necessary to separately perform the assembly work between the master unit and each slave unit, and the work can be simplified.
In addition, another master unit to be exchanged with the original master unit can be wirelessly communicated with all the slave units simply by associating with the slave unit having identification information of the slave unit for wireless communication. As a result, there is no need to work with a handset installed in a high space, and the operator does not need to enter such a space.

  In the connectionless system of the present invention, it is preferable that each of the plurality of slave units has identification information of the plurality of slave units.

According to this configuration, another parent device to be exchanged is associated with one of the child devices, so that the parent device can have identification information of all the child devices that perform wireless communication. For this reason, it is not necessary to specify the slave unit, and the work can be further simplified.
In addition, since the plurality of slave units have the identification information of the plurality of slave units, the risk that the slave unit having the identification information of the plurality of slave units fails together with the master unit and loses the identification information is eliminated.

  As shown in FIG. 5, the wireless master device A includes an LSI 11 as a core member, and other fire alarm devices other than the fire alarm device 1 that detects the occurrence of a fire and 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 non-volatile memory 14. Further, although not shown, the LSI 11 includes a high-frequency circuit unit, a post-modulation processing circuit unit, a microcomputer unit, and the like. 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 both together, 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. Even when the device A is out of order, the association information can be used from the wireless slave devices a1 to a3. In this embodiment, the case where the association information is registered in all of the wireless slave devices a1 to a3 is illustrated. However, the present invention is not limited thereto, and at least one of the wireless slave devices a1 to a3 is used. You may register with. When registering the association information only to a specific wireless slave device, for example, a mark or the like may be attached to the wireless slave device.

  As shown in FIG. 5, the fire alarm 1 includes a CPU 2 as a core member. When a fire is detected by the fire sensor 3, an alarm sound of the buzzer 4 (such as a ping-pong sound) is detected. Buzzer sound or announcement sound such as “Fire alarm activated. Please check” or both, and LED5 lighting or flashing, etc. and various processing to inform the user. Note that the fire alarm 1 is not limited to the configuration in which the CPU 2 is a core member, and an MPU or the like can also be a core member.

  The CPU 2 includes a fire sensor 3 that detects smoke, heat, and the like, a display circuit 6 that controls lighting of the LED 5, a voice output circuit 7 that outputs an alarm sound of the buzzer 4, a wireless master device A, and a plurality of wireless slave devices. An interface circuit 8 for inputting / outputting a signal from a is provided. When the fire sensor 3 detects the occurrence of a fire, the CPU 2 drives and controls the display circuit 6 to light or blink the LED 5, and drives and controls the audio output circuit 7 to generate an alarm sound by the buzzer 4 as described above. To emit.

  In such a wireless system, 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. Lights up and emits an alarm sound from 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. As illustrated in FIG. 4, 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 wireless system according to the present embodiment, as a method of associating the wireless master device A with 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, as shown in FIG. 2, the wireless base station A sets the wireless unit connected from the wireless base unit A at the timing when all the assembly operations are completed or when the installation is completed (for example, after waiting for a predetermined time such as 2 hours). A marriage information transmission code including the IDs of the devices a1 to a3 and 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. According to such a method, in the case where the margin information is registered only in one wireless slave device a in addition to the wireless master device A, the association from the wireless master device A to all the slave devices after the completion of the matching operation is performed. The simultaneous transmission of the information transmission code can be omitted. In the wireless system according to the present embodiment, the case where an ID is used as identification information in the present invention is illustrated. 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.

  In the wireless system according to the present embodiment, when the wireless master device A needs to be replaced with another new wireless master device A ′ due to a failure or the like, as shown in FIG. When the master unit A ′ is associated with any one of the existing wireless slave units a1 having the association information, the wireless master unit A is stored in the non-volatile memory 14 of the wireless master unit A ′. You can register the marriage information you had. As described above, in the wireless system according to the present embodiment, it is not necessary for the wireless master device A ′ to be associated with all the existing wireless slave devices “a”, so that the work can be simplified. Since the wireless master device A ′ also has the ID of the wireless master device A, it can wirelessly communicate with the wireless slave devices a1 to a3 with the ID of the wireless master device A. For example, The wireless slave devices a1 to a3 are instructed to rewrite the ID of the wireless master device A registered in each nonvolatile memory 14 with the ID of the wireless master device A ′, and thereafter the ID of the wireless master device A ′ itself. Thus, wireless communication can be made possible.

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