Aiming at the induction heating workpiece quenching quality and the secure issue during yielding, a new solution based on the induction heating working condition of PLC and MCGS was proposed. The hardware design of induction heating working condition monitoring control system, PLC control program of the lower computer,and the design method of human-machine interface of upper computer were described in detail. The timing sequence and logic control of workpiece quenching working procedure were realized,and the control, operation, display and output were integrated, the safety of induction heating workpiece quenching efficiency and productive process was improved. The quality tracking of the workpiece is achieved, the performance is safe and reliable, so the design goal can be achieved.
