| The article through the designing of computer automatic control systems of parallel-resonance induction reheating-furnaces system. It analyzes the various factors which influence the reliability of the system, under heat-treated environment (eg. high stability and reliability, aberration of electric-net's electric-voltage, difference of ingot' physical state, varies with the environmental temperature dustproof. damp proof, corrosion protection. anti-interference) transducer, PLC, IPC; It have been designed reliably. It proves the controlling system model from both the theory and practice. It designs friendly-operational interface for different operators, using the reliable software to finish the designing.It completely satisfies the request of Pingdingshan of Henan province Donglian Mechanical Manufacture Company the project on productive assembly line. The system can be operated reliably, and the properties have arrived to the request. |
