2. Description of the Related Art Conventionally, as a partner station registration method in a wireless system, a method of pre-registering at factory shipment,
There is a method to register the partner station freely after installation.

As a method for freely registering a partner station after installation, a method for registering an ID code for parent-child communication identification in a slave station simply by mounting the slave station on a slave station mounting section of the master station is disclosed in Japanese Patent Laid-Open No. 7-187
-123469, I received the first time after the power is turned on
As a method of registering the D code as the ID code of the own station, Japanese Patent Laid-Open No. 5-284567, a method of storing the ID code first received by the operation start signal from the parent station after power-on as the own ID code Kaihei 5-2
No. 36545, JP-A-5-137180 as a method for connecting a master station and a slave station by wire via a serial interface and registering an ID code, bringing the master station and the slave station in the vicinity and registering the master station. Japanese Patent Laid-Open No. 3-210838 is known as a method of storing the ID code of the slave station in the master station while the mode switch is pressed to reduce the wireless output.

FIG. 4 shows a sequence diagram of common partner station registration operation of the conventional method. The master station sends a registration start command and the master station ID code to the slave station that is the partner station to register, and the slave station that has received the master station ID code is stored if it has the function of registering the master station ID code.

Next, the slave station sends a registration command and its own station ID code, or the master station ID code stored previously as a slave station ID code, and if the master station has a function of registering the slave station ID code, the slave station The station ID code is stored, a registration end command is sent, the slave station sends an end command, and the registration operation ends.

[0006]

However, in such a conventional partner station registration method, although the partner station is required to be reliably registered, at least at the beginning, the master station must have its own ID. Only the code is sent to the partner station, and it is unknown whether or not the slave station is for its own station. Therefore, when multiple systems perform the partner station registration operation at the same time, the station that has transmitted the ID code becomes the partner. There is a high possibility of misregistration as a station, and in order to prevent misregistration, the master station and slave stations are connected by wire or in the vicinity, and are registered in a different installation state from the normal wireless communication state. There is a problem that means is required, the registration operation becomes complicated, and the equipment becomes expensive.

The present invention solves such conventional problems,
It is an object of the present invention to provide a partner station registration method in a wireless system that can prevent erroneous registration with a simple and inexpensive registration operation.

[0008]

In order to solve this problem, a partner station registration method in a wireless system according to the present invention is a child station in which a master station connected to a host computer by wire is a partner station previously input to the host computer. Station ID
Interface means for inputting a code from the host computer, ID code storage means for storing the input ID code of the slave station and the previously input ID code of the local station, and the ID of the stored slave station The remote station has wireless transmission means for transmitting the code and the ID code of the own station, and the slave station as the partner station wirelessly receives the ID code of the master station and the ID code of the slave station, and the ID code of the slave station is input in advance. It has an ID code storing means for storing the ID code of the master station only when it matches the ID code of the own station, and a wireless transmission means for transmitting the stored ID code of the master station and the ID code of the own station to the master station. It is configured.

According to the present invention, even if a plurality of systems are simultaneously performing registration operation of partner stations, a special registration means for preventing erroneous registration is not required, and the original partner can be reliably ensured in a normal wireless communication state. You can register stations.

[0010]

The master station 8 that has received the slave station ID registration instruction via the C control unit 6
Starts the slave station ID registration operation. The slave station ID code is received from the host computer 7, and this slave station ID code is stored in the ID code memory unit 5. If there is an ID registration instruction of another child station, the state returns to the child station ID receiving state again, but if there is no ID registration instruction of another child station, an end instruction is received and the child station ID registration operation is ended.

Next, the ID code of the master station 8 is registered in the slave station 18. The master station 8 transmits the ID registration mode signal, the master station ID code, and the slave station ID code together as a wireless signal. Upon receiving the ID registration mode signal, the slave station 18 starts the master station ID registration operation. The slave station ID code of the received signal is compared with the own station ID code, and if they match, the master station I
The D code is stored in the ID code memory unit 15. If they do not match, the wireless signal reception is simply repeated. Child station 1
When the master station ID code is stored, 8 transmits the master station registration operation end signal, the master station ID code, and the slave station ID code together, and sends and receives a confirmation signal with the master station 8 to register the master station. The operation ends.

As described above, when the slave station 18 is registered in the master station 8, the registration operation is performed by an instruction from the host computer through the wire RS232C, and when the master station 8 is registered in the slave station 18, the master station 8 is registered. The station 8 receives the ID registration mode signal,
By transmitting the master station ID code and the slave station ID code together, and by transmitting the master station ID code and the slave station ID code together when the slave station 18 also transmits the master station registration operation end signal. In the state of normal wireless communication, the original partner station can be surely registered.
