摘　　要：利用DDE技术实现VB和组态王的动态数据交换,以弥补组态王在复杂控制算法及数据处理上存在的不足。系统下位机采用研华ADAM-5510可编程控制器,实现对小型EFPT过程控制装置的温度、压力、流量、液位等四大热工参数的多个模拟量的实时数据采集,同时在上位机的VB应用程序里实现对装置锅炉温度和锅炉液位的实时控制。The dynamic data exchange between Visual Basic application program and king view by DDE technique is implemented,which makes up the shortages of KingView for complex control algorithms and data processing.The ADAM-5510 programming controller is used to realize real-time date acquisition for the parameter the EFPT process control equipment which contain the temperature,pressure,flux and hydraulic location,etc.At the same time,it realized the real-time control for temperature and hydraulic location of EFPT through VB application program.
