| 摘要: |
| 介绍了一种使用VC 和OPC TookLkit工具包实现OPC驱动程序的通用方法。按照对驱动程序结构的要求，使用以上开发工具生成多个工程，共同组成程序框架。在对通信协议进行分析的基础上，进行实现方式的设计。按照协议的要求，在不同的协议层次上，分别实现协议的封装用分析。实现标准的OPC接口，可以直接和任何支持此规范的客房端进行通信，增强了适应性。程序还使用了多线程技术，使多个功能块可以同步运运行，缩短了程序循环周期，因而更具高效性。在iFix和多个标准OPC客户端得到了良好的运用，表明此方法在电力系统自动化和通信领域具有广泛的应用前景。 |

| Abstract: |
| A general realization of OPC driver using Visual C++ and OPC Toolkit is explained. At first, according to the requirement for the driver, several projects are developed with the tools mentioned above to build up a framework. Then the realization method is designed based on the full analysis of the communication protocol. In different layers, the pack and unpack of the message are realized as required by the protocol. The standard OPC interface is applied to directly communication with clients who support the protocol and the compatibitity is thus improved.The muti thread technique is adopted to enable several functions running concurrenuy and the function circulation period is thus shorten to improve the efficiency.The driver now is applied well in iFix and oter OPC clients.It indicates that the method can be widely used in the automation and communication fields of electric system. |
