The invention discloses a human-machine interaction system of a charging pile The human-machine interaction system comprises a PLC controller and a touch screen, wherein the PLC controller is electrically connected with the touch screen through a communication cable; the PLC controller is used for receiving a charging request of the touch screen and operating the charging request through a pre-written program to control a charging process Therefore, the problem of a communication defect between the PLC and the touch screen in the relevant technology is solved, and accessible connection between the PLC and the touch screen is realized

Human-machine interaction system of charging pile

The utility model provides an S7-200-based dynamic tuning passive filter device comprising a tuning return circuit and a control circuit. The tuning return circuit comprises an air switch, a variable reactor and a capacitor bank. The control circuit comprises a current and voltage sensor, a PLC, a touch screen, a harmonic wave collection module, a trigger pulse generator, and a D/A conversion extension module. The PLC serves as the main controller of the S7-200-based dynamic tuning passive filter device, the D/A conversion extension module is used for control of trigger signals of the trigger pulse generator and reactance of the variable reactor is changed through change of the conduction angle of an antiparallel thyristor, so that the problem of resonance point drifting of the conventional passive filter device during long-time operation can be solved intelligently. The S7-200-based dynamic tuning passive filter device guarantees stable system operation and high control precision.
