Lei Zhou · Pipeline Technique and Equipment · 2008
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.
