动态称重控制器OPC驱动程序设计

Design of OPC Driver for Dynamic Weighing-machine Controller

以开发动态称重控制器的上位机控制软件为背景,介绍了使用VC++实现OPC驱动程序的通用方法。通过引入多线程异步传输、哈希链式存储和DLL封装等技术,优化了数据处理性能,提高了软件开发和维护效率。在使用WinCC和iFix等组态软件开发的分布式控制系统中,该驱动程序运行良好,已得到实际应用验证。

A general method of OPC driver realization based on the platform of VC is presented,on the background of developing PC- based communication software for the dynmic weighing - machine controller. The multi - thread asynchronous data transfer,Hash chain storage and DLL encapsulation techniques are introduced into the driver, which improves the performance of data - processing and makes the development and maintenance more efficient. The driver is well in commission in the distrubuted control system develped with WinCC or iFix.
