[0006] The present invention solves the above-mentioned conventional problems, and provides a wireless device capable of easily and automatically shifting from a wired system to a wireless system by automatically setting a wired communication protocol. To aim.

[0007]

A wireless device of the present invention is a wireless device having a normal wireless communication mode and a communication condition identification mode used when shifting from a wired system to a wireless system. In the mode, monitor means for monitoring wired communication performed between devices, communication condition identifying means for identifying communication conditions from communication data monitored by the monitor means, and communication conditions identified by the communication condition identifying means are automatically set In addition, the communication condition setting means for automatically setting the communication condition transmitted from the outside and the communication condition transmitting means for transmitting the communication condition set by the communication condition setting means to the outside are provided. The normal wireless communication mode is executed on the basis of the communication condition set in 1., thereby achieving the above object.

Preferably, in the wireless device of the present invention, the mode is connected to the information processing device and is also connected to a peripheral device or the information processing device by a monitor cable to switch between the normal wireless communication mode and the communication condition identification mode. Switching means is provided, and when the communication condition identification mode is selected by the mode switching means, the wired communication data to the monitor cable is monitored to automatically set the communication condition of the wired communication data, and the normal wireless communication by the mode switching means is performed. When the mode is selected, communication is performed with the information processing device based on the automatically set communication condition.

Further preferably, in the wireless device of the present invention, a connection state detecting means for detecting the connection state of the connector portion on the side to which the monitor cable is connected with the monitor cable, and the monitor cable with the connector portion. And a switching means for forcibly switching to the normal wireless communication mode regardless of the state of the mode switching switch when not connected.

Further, preferably, in the wireless device of the present invention, when the wired communication data is monitored and the wired communication condition is identified, “in the middle of communication condition identification”, and when the identification of the wired communication condition is completed. The message "End of communication condition identification" is displayed, and when the communication protocol of the wired communication line does not match, or when the wired communication condition cannot be identified such as the information required for identification does not exist in the communication data, communication is performed. The display means is provided for displaying a message that the condition is "unrecognizable".

Further preferably, in the wireless device of the present invention, when wirelessly communicating the communication conditions to a wireless communication destination by wireless communication, it is detected that the wireless communication is not correctly performed, and a "communication condition transmission error" is detected. The display means for displaying the message "" is provided.

[0012]

With the above configuration, even when the control procedure is changed when the wired system is transferred to the wireless system, the wireless device side can communicate the wired communication condition such as the complicated control procedure program or the control procedure setting parameter to the communication data. Is monitored by the monitoring means, and the communication condition is identified by the communication condition identifying means from the monitored communication data. The identified communication condition is automatically set by the communication condition setting means, and the communication condition transmitted from the outside is automatically set by the communication condition setting means. Further, the communication condition set by the communication condition setting means is transmitted to the outside by the communication condition transmitting means, and the normal wireless communication mode is executed based on the communication condition set by the communication condition setting means.

In this way, the wired communication line is monitored in the communication condition identification mode, the communication protocol is identified, and the communication condition is automatically set. Further, the set communication condition is transmitted to the other communication destination wireless device, and the communication condition is automatically set in the same manner as the communication source wireless device. This makes it possible to easily replace the wired data communication system with the wireless data communication system without developing and changing the communication protocol of the wired communication line.

As described above, by providing the wireless device with the function of receiving the communication condition, the wireless device of the communication source can have the same function as the wireless device of the communication destination on the wireless data communication system. In other words, the wireless device is provided with a communication condition identification function and a setting function, and in addition to transmitting the set communication condition, it also receives the communication condition transmitted from another wireless device and sets it as its own communication condition. It has a function to do. In this way, the wireless device can be connected to either the information processing device and the peripheral device or the information processing device, which is economical.

Further, by providing the mode switching means in the wireless device, the mode switching can be performed at an arbitrary timing. This makes it possible to easily switch between the normal wireless communication mode and the communication condition identification mode.

Further, after automatically setting the communication conditions in the communication condition identification mode, when switching to normal wireless transmission, the mode switching means does not operate normally when the mode is in the communication condition identification mode. To prevent this, the wireless device has a monitor cable connection detection function, that is, when the monitor cable is not connected by detecting the presence / absence of connection of the monitor cable, the wireless device automatically detects the connection regardless of the mode state. It should be operated in normal wireless communication mode.

Further, the automatic setting of the communication condition identification mode of the wireless device is completed, and the communication condition is transmitted to the wireless device of the other communication destination, but since various kinds of communication protocols are monitored, the individual communication protocols are monitored. Therefore, the time required for communication condition identification differs and is uncertain. For this reason,
By displaying the message indicating that the wired communication condition is being identified in the communication condition identification mode and the message indicating the end of the message display on the display means, the operation state can be confirmed.

Further, if the wireless communication device is a special device that is out of the protocol standard of the wired communication line and cannot be identified by this wireless device, or if the information necessary for the identification does not exist in the communication data, the wired communication condition is identified. I can't. Since normal wireless communication cannot be performed without being identified, it is possible to confirm whether the communication conditions have been set correctly by displaying the communication condition identification error message indicating that the communication could not be identified. Become.

Further, when the communication condition is communicated to the communication destination wireless device through the wireless communication line, the communication condition data may not be transmitted due to a too long communication distance or a shield. In this case, in order to indicate that the communication condition could not be set for the wireless device of the communication destination, a message display indicating whether the wireless transmission of the communication condition was correctly performed to the wireless device by the wireless response reception function of the wireless device. By doing so, it becomes possible to confirm whether or not the communication condition is set in the wireless device of the communication destination without error.
