摘　　要：在过程工业的控制中存在着大量的通信协议,这些协议基本都是建立在数据帧的基础之上,其差别在于数据帧的格式,要对协议进行解析和处理,只需要对相应的数据帧进行解析和处理即可。讨论了用形式化描述的方法对数据帧格式进行描述,并在此基础上实现与数据帧格式无关的数据帧解析和处理。从而避免了针对不同通信协议的数据帧格式均要编写相应的解析和处理程序,使协议的解析和处理具有更好的灵活性和普适性。In process industry, there are many communication protocols. Most of these protocols are based on data-frame, but have different formats. In order to parse and process these protocols, only have to parse and process corresponding data-flame. The dataframe parsing is discussed and processing program is implemented when the data-frame format is described with the formalize-description, and the program based on formalize-description is independent of the data-flame format. This implementation can avoid coding parse and process program for different data-frame format separately, and make the program more flexible and the adaptable.
