本文提出了以负荷分担方式组成微计算机双机容错系统的设想,讨论了这种双机容错系统的特点,结构设计和软件设计的方法.这种双机系统具有处理能力强,可以采用多种双机信息交换方式,多种故障测试、故障诊断方法和可靠性高等多方面的优点.用两台RECZ-80单板机构成的系统进行了初步的原理性试验,结果表明,这是一种容易实现的、较好的双机结构形式.
In this paper, the idea of composing a microcomputer dual fault tolerant system with load sharing is proposed, and the characteristics, structural design and software design of the dual fault tolerant system are discussed. The dual system has the advantages of high processing power, Double machine information exchange mode, a variety of fault tests, fault diagnosis methods and high reliability, etc .. The principle of the experiment with two RECZ-80 single-board machine made a preliminary test results show that this is a Easy to implement, better dual machine structure.
