摘 要:针对目前组态王与智能化仪表通信时存在的问题,基于VB和动态数据交换技术DDE,研究了组态王与VB数据交换的方法,并采用VB可视化的编程方法,编写了上位机与智能化仪表间的串口通信程序及组态软件与VB间的OLE数据交换程序。实现了组态王与智能化仪表的实时通信,间接扩展了组态王的驱动程序库。另外,设计完成了基于组态王和VB的智能化仪表监控系统。运行结果表明,该系统具有良好的稳定性、实时性,可以较好地实现工业现场的实时监控。Aiming at the existing problem of communication between Kingview and intelligent instruments, the method of data exchange between Kingview and VB is researched based on VB and DDE technology. With the visual programming method of VB, the serial port communication program between host computer and intelligent instrument and the OLE data exchange program between VB and configuration software written, thus real-time communication between Kingview and intelligent instrument is implemented ; and the library of driving programs of Kingview is expanded indirectly. In addition, the monitoring system based on Kingview and VB for intelligent instruments is designed and completed. The result of operation shows that the system features excellent stability, real-time performance, and suitable for real-time monitoring in industrial fields.
