农田供水远程监控中组态王与Delphi的通信实现

Implementation of the Communication between King View and Delphi in the Control System of Water Supply Remote Monitoring for farmland

根据供水所的需求,开发了基于Delphi和组态王的农田供水远程监控系统。对系统的硬件组成和软件设计进行了分析研究。分析了Delphi和组态王的通讯原理,并给出了实现过程。Delphi可以通过动态库、Excel、ActiveX控件、API函数等扩充组态王的功能,为工业控制提供了一种新的组态方案。

The water supply remote monitoring control system was designed according to the hydropower station need.The hardware and software design of system were discussed in detail.The implementation of the communication between KingView and Delphi was studied.The data communications of Delphi and KingView were realized with DLL,Excel,ActiveX control,Windows API function,etc.So the the function of KingView was expanded.
