基于OPC和VB的SCADA系统的数据通信方法

Data Communication Method of SCADA System Based on OPC and VB

简要介绍了OPC在工业中的应用和它的结构,并以石油天然气管道的SCADA系统为背景,利用VB和OPC自动化接口,通过同步方法定时采集SCADA系统的数据,为管道后期的优化、仿真及泄漏监控提供高效的操作方法。

Here is briefly introduced the industrial application of OPC and its structure. Based on the SCADA system of oil and gas pipeline, using VB and OPC automatic interface, the data of SCADA system are acquired at a fixed time span with a synchronous method, which provides an effective operation procedure for pipeline optimization, simulation and leakage supervision in the later phase.
