摘要
在计算机控制系统中程序运行监视系统(WATCHDOG)是一个最佳的软硬件相结合的抗干扰措施。本文根据WATCHDOG的原理,结合计算机数控系统的特点介绍了一种由可编程定时/计数器,由INTEL18253构成的应用在计算机数控系统中的WATCHDOG电路及其程序设计方法。
The program running monitor system (Watchdog) is the best anti - disturbance method combined with hardware and software in the computer control system. A ccording to the pricple of watchdog and the characteristic of CNC system, a watchdog which is need in the CNC system is introduced in this paper . The watchdog is composed of the programmable timer/counter intel - 8253. The design of the circiuts and the control program is also discussed in the paper.
