本文分析用于控制系统的微计算机的故障类型,介绍了屏蔽故障,提高运行可靠性的措施。这些措施主要应用容错技术中的软件、信息、时间冗余,称之为“故障软化”技术,它能使计算机出现故障后不影响系统的正确工作,并能自动恢复。对于那些因元器件损坏而出现的固定故障,能够检出并确认。本文主要讨论:1.计算机常见故障;2.看门狗技术;3.信息冗余技术;4.时间冗余技术;5.关键值容错修正;6.人的操作容错;7.运行过程记录。 This article analyzes the type of microcomputer used to control the system, describes the shielding failure, measures to improve operational reliability. These measures mainly use software, information and time redundancy in fault tolerance technology, which is called “fault softening” technology, which can make the computer malfunction without affecting the correct operation of the system and recover automatically. For those who fail due to components of the fixed failure, can be detected and confirmed. This article mainly discusses: 1 computer common fault; 2 watchdog technology; 3 information redundancy technology; 4 time redundancy technology; 5 key value fault-tolerant correction; 6 human fault-tolerant operation; .
