Abstract
To unify some devices' interfaces in remote monitoring system,based on VC++ platform,an OPC proxy was designed and exploited by employing object-oriented technology and Standard Template Library(STL).The proxy was mainly composed of four modules: The standard OPC interface module,the device driver module,the configuration module,and the data buffer.This OPC proxy could be accessed flexibly by different devices.The tests show that it has good stability and portability,and it meets the requirements well.
