CK-I型车床闭环控制系统的软件抗干扰设计

Design of Software Anti-interference for Model CK-I Close-loop Control System of Lathe

针对CK I型车床闭环控制系统,分析了干扰的起因及后果;提出了几种软件抗干扰的措施,包括数字信号的输入与输出、CPU的抗干扰以及关键数据的恢复。实践表明,这些软件抗干扰的措施经济实用,提高了控制系统的可靠性。

The causes and consequences of interference are analyzed in the paper. For model CK-I close-loop control system of lathe, several kinds of software anti-interference measures are presented, which include the input and output of the digital signal, the anti-interference of CPU and the restoration of crucial data. The practice shows these measures are economical and practical, and the reliability of the control system is improved.
