摘要
针对加热反应炉在送料、温度、压力等条件变化时不能实施有效控制的问题,采用东芝公司的 E X- 20 P L C对其电气设备进行改造,软件编程采用步进梯形指令.改造后的控制系统性能稳定,工作可靠,生产效率大大提高.
Some ways of antiinterference about microcomputer test system for motor is presented,such as electricity supply,shield,ground connection,information connection,information passageway in hardware and the fault tolerant techniques and digital filtering methods in system software.So the system has stable performance and safe work to strengthen antiinterference ability.
