Abstract: The software availability of a control system is analyzed.For model CK-I closed-loop control system of lathe,several kinds of measures for improving software availability are presented,which include the input and output of digital signal,the anti-interference of CPU,the usage of counters of CPU,the restoration of crucial data and the counting value reading of Intel 8253.The practice shows that these software measures are simple,economical and practical,and the availability of the control system is improved.
