Abstract:
Here is briefly introduced the industrial app lication ofOPC and its structure. Based on the SCADA system of oil and gas p ipeline, using VB and OPC automatic interface, the data of SCADA system are acquired at a fixed time span with a synchro-nousmethod,which p rovides an effective operation p rocedure for p ipeline op timization, simulation and leakage supervision in the later phase.
Key words:
OPC Server;VB; SCADA system; oil and gas p ipeline
