CONTROL SYSTEM OF FULL-AUTOMATIC COLD PLASMA SEED PROCESSOR

摘要

A control system of a full-automatic cold plasma seed processor comprises a human-machine interaction interface, a PLC controller, a transport module, a vacuum degree module, an ionization module, and an energy supply module. The human-machine interaction interface is in a communications connection with the PLC controller by using a serial port. The energy supply module supplies a power source required by another module in a system. The PLC controller controls a transport rate of seeds by using the transport module, controls, by using the vacuum degree module, the vacuum degree of the system to reach a dynamic balance, and at last, controls the ionization time and the ionization power by using the ionization module, so as to adapt to processing requirements of different seeds and achieve an optimal processing effect. The control system can automatically process seeds of various grains, and brings short processing time and low cost.
