OPC服务器研究及实现

RESEARCH AND IMPLEMENTATION OF OPC SERVER

随着工业控制技术快速发展,出现了许多互不兼容的硬件和应用软件,为了解决这个问题,OPC标准技术规范应运而生。OPC规范使软件开发者只专注程序本身,而不必考虑各项硬件的差异性。本文在介绍了OPC规范后,演示了基于无线传感器采集系统的OPC服务器开发、测试和发布。目前国内外有多种综合录井仪传感器采集系统,其采集方式自成体系,没有统一接口,可以使用OPC规范进行传感器采集接口的统一。

With the rapid development of industrial control technology,a lot of incompatible hardware and application software appeared.In order to solve this problem,the OPC standard specification emerges as the times require.OPC specification makes software developers focus solely on the program itself without considering the differences of various hardware.This paper introduces the OPC specification,illustrates development of the OPC server based on wireless sensor acquisition system,testing,and release.There are a number of comprehensive logging instrument sensor acquisition systems at home and abroad,which acquisition modes are sui generis without unified interface.The OPC specification provides unified acquisition interface.
