本文论述一个利用单台微型机控制96个通道的控制系统的设计思想和实现措施,该系统采用中断分时处理方式,充分提高了CPU利用率,实现控制24个啤酒发酵罐的工作,该系统具有人机对话和与后备机实时通讯的功能,可依生产需要随时更改工艺参数和改变工作进程,使得系统控制功能灵活、操作方便、並提高其可靠性,本系统设计充分发挥计算机软硬件结合的特点,因而大大简化了系统输入,输出电路,降低了系统的造价。
This article discusses a single microcomputer control 96-channel control system design ideas and implementation measures, the system uses interrupt-based time-sharing approach to fully improve the utilization of the CPU to achieve the control of 24 beer fermenter work, the system With man-machine dialogue and real-time communication with the backup machine functions, according to production needs at any time change the process parameters and change the work process, making the system control flexible, easy to operate and improve its reliability, the system design to give full play to the combination of computer hardware and software The characteristics, thus greatly simplifying the system input and output circuits, reducing system cost.
