Control systems for vacuum ion beam polishing machine and communication method of control systems

The invention relates to control systems for a vacuum ion beam polishing machine. Each control system comprises a vacuum control unit, an ion source control unit, an ion source movement control unit, a PLC, an I/O expansion module, an upper computer and a man-machine interaction screen. The vacuum control units and the ion source control units are in communication connection with the upper computers through the PLCs. The ion source movement control units and the upper computers are in communication connection. The invention further relates to a communication method of the control systems for the vacuum ion beam polishing machine. Configuration control interfaces of all the control units are added to the man-machine interaction screens through man-computer interface architecture, data acquired by the upper computers from the vacuum control units, the ion source control units and the ion source movement control units are used for updating the displayed content on the configuration control interfaces of the vacuum ion beam polishing machine in real time, all the control systems in the vacuum ion beam polishing machine are monitored and managed in a unified manner, the amount of information is large, and operation is convenient.
