一个成功的微型计算机工业控制系统,它的计算机系统必须是可靠的,而控制质量在测量精度有了保证的条件下,则完全取决于控制方案。所以研制一套高可靠的计算机系统就成为工业控制的前提。在某些必要场合,采用容错技术是提高可靠性的良好途径。冷备份冗余在理论上可靠性最高,
A successful microcomputer industrial control system, its computer system must be reliable, and the quality of control in the measurement accuracy is guaranteed conditions, it is entirely dependent on the control program. Therefore, the development of a highly reliable computer system has become a prerequisite for industrial control. Using fault-tolerant techniques is a good way to improve reliability in certain occasions. Cold backup redundancy in theory, the highest reliability,
