Abstract:An integrated monitoring and control system for induction hardening is presented, which is integrated the induction quenching energy monitoring and environmental monitoring function based on IPC and Y5000+ multifunction board. The IPC communicates Y5000+ multifunction board through its parallel port. Y5000+ multifunction board is designed with CPLD chip as the core and constructed of the DI/DO, PI/PO and AI/AO modules. The application of the integrated monitoring and control system for induction quenching is divided into the upper management subprogram and the bottom real time measurement and control subprogram. With the support of RTX, the system can meet the requirements of real-time and reliability.
