摘要
以羰基合成模式评价装置控制系统为研究对象,讨论了上位PC机中的组态王监控软件与单片机组成的下位机智能化仪表间的通讯问题。给出了组态王与自制的智能仪表之间的动态数据交换方式,阐述了以VB编制的服务程序与组态王之间通过DDE方式、与单片机之间通过串行通讯方式实现的上下位机间的数据通讯。
In this article, according to control system of the carbonyl compound mode evaluation device, communication problem of the PC and intelligence instruments making up of single-chip is discussed . Dynamic data exchange between the Kingview and the intelligent instruments is presented. DDE mode between VB application program and Kingview, and serial data communication between VB application program and Kingview are expatiated in this paper.
