The PLC-PC Supervision System based on Configuration Software

Through the analysis of the characteristic of the monocoil permanent magnetic, this article introduces one of the intelligent devices for one of Monostable Permanent Magnetic Operating Mechanism using chip microcomputer, analyses the design procedure and operating principle in detail, and supplies amplifying, filtering, analog - digital converting circuit at the same time. This article applies ORCAD simulation software, emulating the current changing curve of the vacuum circuit breaker in the switching and splitting process. The intelligent device supplies the various protection instructions and software code in the controlling process, and supplies the design method of EMC at the last.
