Design and Application of OPC Client to Intelligent Three-dimensional Garage

An intensive research is made into the OPC specification of data access and the workflow of the OPC client,then the OPC client is realized based on the OPC custom interface in the C++ language.In addition,the sink in the OPC client is constructed and the multi-thread mechanism is realized.Finally,the reliability of this OPC client is confirmed through the application in an intelligent three-dimensional garage.
