摘要
计算机控制系统的可靠性是涉及到它是否能在工业市场上广泛应用的关键。在使用的计算机控制系统中,由于存在着大量的干扰,常常导致系统不能正常工作,因此可靠性设计越来越得到人们的重视。分析了计算机控制系统中干扰的来源,并且从硬件和软件两方面给出了提高控制系统可靠性的具体对策:硬件的选择元器件、冗余技术、电源干扰的抑制、电场和磁场干扰的抑制、接地技术及通道上的抗干扰措施;软件的软件工程方法、软件固化及自诊断技术。
Whether a computer control system is widely used is determined by its reliability. In the computer control systems, there are lots of interaction, which can＇t make the system work normally, so more attention is paid to reliability design. The origin of jamming in computer control system based on microcomputer is analyzed, and simultaneously some concrete countermeasures for improving reliability in computer control system are given both in aspect of hardware and software： Sereenmethodofcomponents, redundancy technology, inhibition of power interference, inhibition of electric field and magnetic field interference, touchdown technology and channel interference protection measures in hardware, and the technology of software engineering, software solidify and self-diagnose in software.
