Data transmission method and system based on OPC

The invention relates to the technical field of industrial process control data acquisition, in particular to a data transmission method and system based on OPC. The data transmission method based onOPC comprises a data acquisition module, a data configuration module, a data interface execution module and an MES management module. The data acquisition module is connected with the data configuration module through an OPC address module, the data configuration module is connected with the data interface execution module through a custom interface module, and the data interface execution moduleis connected with the MES management module. And acquisition of process data, issuing of process data and signal processing are realized. 本发明涉及工业过程控制数据采集技术领域，一种基于OPC的数据传输方法及系统。所述一种基于OPC的数据传输方法包括：数据采集模块、数据配置模块、数据接口执行模块以及MES管理模块；所述数据采集模块通过OPC地址模块与数据配置模块相连接，所述数据配置模块通过自定义接口模块与数据接口执行模块相连接，所述数据接口执行模块与MES管理模块相连接。实现过程数据的采集、工艺数据的下发，信号处理。
