In this paper, we study the steel belt vacuum continuous coating system, including the drive system (speed, tension control, etc.), vacuum system (pump, valve, etc.) and coating system (vacuum degree, target power, mixed gas, temperature, etc.) the three systems.As con- trol variables, the switch quantity is various, scattered field devices, industrial environment is
