Measurement and Control System for Traction Motor Based on OPC Technology
Abstract:
The paper analyzes the working principle and the advantages and disadvantages of synchronous access and asynchronous access in OPC standard. Take the traction motor performance test and control system as example. It used Visual Basic development OPC client and used PC Access as an OPC Server. The performance test bed for traction motor realize the measurement and control system efficient, stable and reliable operation. According to the characteristics of different parameters, the system chooses the methods of Subscription and Synchronous Write which used the advantages of synchronous access and asynchronous access.
