摘要
阐述基于TCP/IP Socket的电文通信中间件在中南股份特棒过程控制系统(PCS)的应用。电文通信中间件采用TCP/IP协议,静态套接字(Socket)同步通信机制,通过创建Socket、绑定、监听、接受信息和关闭套接字实现与MES系统、PLC系统间的数据交互,并对通信电文数据校验,数据清洗、数据转换、数据存储。从电文定义、数据格式、通信过程等介绍电文的通信规约,在遵循通信规约的前提下,可在不同的操作系统、不同编程语言开发的应用程序间进行电文通信,提供了简单易用、高效可靠的分布应用开发和通信平台,可快速高效开发稳定可靠的分布式应用。
The application of a message communication middleware based on TCP/IP Socket in ZNIS Special Rod Process Control System(PCS)is elaborated.The message communication middleware adopts TCP/IP protocol and a static socket synchronous communication mechanism.By creating a Socket,binding,listening,receiving information,and closing the socket,data interaction with MES and PLC systems is achieved,and communication message data is verified,cleaned,converted,and stored.This article introduces the communication protocol of messages from the perspectives of message definition,data format,communication process,etc.Under the premise of following this communication protocol,message communication can be carried out between applications developed in different operating systems and programming languages.It provides a simple,easy-to-use,efficient and reliable distributed application development and communication platform,which can quickly and efficiently develop stable and reliable distributed applications.
