Design of New Intelligent Combined Magnetic Control Station

Based on the analysis of mine asynchronous motor’s work, a new intelligent measurement and control system for vacuum magnetic control station is developed by using Intel 80C196KB as central control unit. The system can automatic change control modes and is provided with protective functions for short circuit, overload, open-phase, over-voltage, under-voltage, leakage, etc. Meanwhile, it displays operation condition and work parameters of all load lines by Chinese character display terminal. Much more attention is paid to hardware components, functional modules of software and anti-interference methods of the system. The simulated experimental result shows that the measurement and control system has practicability, reliability and safety to a certain degree.
