The present invention relates to a parameter setting device for a machine and its parameter setting method.

Conventionally, in a production site such as a factory, various inspections are performed in a product inspection process. In this case, a plurality of measuring devices are placed at the location of the inspection process, physical quantities such as product length and weight are measured, and these measurement data are sent wirelessly to a host computer located in the center, and the host computer The quality level is calculated.
As an example of the measuring device used in the inspection process as described above, a measuring instrument that can display digital measurement data and that can send out the digital measurement data and wirelessly transmits the digital measurement data from the measuring instrument. A measuring device including a wireless device is known (Patent Document 1).
When the measurement device outputs digital measurement data from the measuring instrument by operating the transmission button while pressing the ID number setting button, the data of a specific digit in the digital measurement data is directly stored in the storage unit as the ID number. It is intended to be memorized.

  By the way, the radio transmitter / receiver of the measuring device includes, for example, a channel number for determining a used frequency band, a receiver number for pairing, bidirectional / unidirectional setting for bidirectional communication or unidirectional communication, It is necessary to set parameters for setting wireless communication conditions such as transmission output, setting communication conditions between the measuring instrument and the wireless device, and setting functions such as a confirmation sound at the time of transmission and reception and display LED emission conditions. There are the following methods for setting these parameters.

(I) Various setting buttons and numeric keys are arranged on the wireless device, and parameters are set on the microcomputer mounted on the wireless device by operating the various setting buttons and numeric keys.

Since the operation after the measurement operation unit of the measuring instrument 3 is operated is the same as that of the measuring instrument 3 in the first embodiment, a description thereof will be omitted.
In the wireless device 7, various operations are controlled based on a control command from the main control unit 75.
Digital measurement data sent from the measuring device 3 via the connector 36, connector 50, and cable 5 is captured by the signal processing unit 744 and supplied to the wireless communication control unit 743. The wireless communication control unit 743 provides the digital measurement data to the modulation unit 741 for modulation, and outputs the modulated signal to the wireless transmission unit 733. The wireless transmission unit 733 sends a wireless transmission signal to the antenna 731 via the transmission / reception distributor 732. Thereby, the digital measurement data is transmitted from the antenna 731 to the air as radio waves.
