【Abstract】 In this paper,controlling principle,technical requirement and protective functions of measurement and control system for vacuum magnetic switchgear based on PLC is introduced,also the design methods of monitor routine and functional module programs with flow charts and the specific solutions for the problems come up against in the course of program designing.In addition to this,interference factors affecting the nor-mal operation of measurement and control system are analyzed and the relevant interference protection mea-sures of software are worked out.From the preliminary operation of magnetic switchgear it can be proved that the measurement and control system applied with the application programs which are introduced in the paper indicates more utilizable,reliable and safe than other traditional like systems.更多还原
