计算机测控系统中的可靠性技术

The research for reliability on computer auto control system

计算机测控系统的工作环境往往是复杂、恶劣的,影响测控系统可靠、安全运行的主要原因是来自系统内部和外部的各种电气干扰．抗干扰技术和可靠性设计是计算机测控系统不可忽视的重要内容,本文针对各种常见的干扰,仔细论证和分析常用的抗干扰技术,分别从硬件抗干扰和软件抗干扰进行讨论．硬件抗干扰主要有电源抗干扰、传输通道抗干扰;软件抗干扰有数字滤波、重复设置、软件拦截等．

The computer selfmotion control system working conditions often are complex and bad, affects the auto control system to be reliable, the safe operation main reason is comes from the system interior and the exterior each kind of electrical interference. Therefore, the antijam technology and the reliability design are the computer selfmotion control system noticeable important content, the commonly used antijamming technology mainly has the hardware antijamming and the software antijam. The hardware antijam mainly has the power source antijamming and transmits the channel antijamming. The software antijamming technology has digital filter, repetition establishment, software trap and so on.
