一位微处理机在工业现场运行时往往会遇到大动力负荷及各种电器(如电机、电焊机、继电器、接触器、电磁阀……)开启、关断时所引起的电网电压波动及强电磁场的辐射干扰。能否经受住工业现场复杂环境的考验是关系到一位微处理机用于工业现场成败的重要问题,为此,必须对其抗干扰性能进行考核。一九八三年四月,北京半导体器件三厂、北京椿树电子仪器厂、航空工业部六○八研究所在湖南省株洲市对LTS-82机进行了一系列模拟工业现场工作状况的抗干扰试验。现将其抗干扰考机方案之一介绍如
A microprocessor in the industrial field often encountered when running a large power load and a variety of electrical appliances (such as motors, welding machines, relays, contactors, solenoid valves, etc.) open, shut down when the grid voltage fluctuations caused by and Strong electromagnetic field radiation interference. Can withstand the test of complex industrial environment is related to a microprocessor for industrial site success or failure of the important issues, therefore, must be its anti-jamming performance assessment. In April 1983, Beijing Semiconductor Equipment Factory No. 3, Beijing Chunshu Electronic Instrument Factory and No. 608 Institute of Aviation Industry carried out a series of tests on the LTS-82 machine in Zhuzhou City, Hunan Province to simulate the industrial working conditions Interference test. Now its one of the anti-jamming test machine introduced such as
