摘要: 系统用价格便宜的个人计算机及单板机分别作为二级和一级控制机.两级之间采用中断 与查询相结合的联络方式使两级异步工作,用随机交换信息的方式以减一级内存容量和增加 二级管理台数.两级之间通过调度程序把BASIC语言与汇编语言融合在一起,以达到操作方 便和控制速度快的要求.Abstract: This system consists of two levels. A cheap personal computer is used as the main machine and single board computer is used as slave machine. The method of interrupt and inquire is applied for hand-shake. A specific random fill-in model is applied for information exchange between the two levels, so as to minimize internal storage of the first level and to increase the number of the controlled machines by the second level The schedule program schedules BASIC and ASSEMBLER for the convenience of the operators and fast response of real-time control.
