摘要:: 北京油气调控中心在整合陕京一线SCADA 系统时，将其原有的Modbus 协议串口通信升级为基于TCP/IP 的IEC60870-5-104 协议（简称IEC 104 协议）网络通信。IEC 104 协议的实现要点：主站和子站之间使用的IEC 104 协议基于网络传输层可靠的TCP 传输协议；主站（客户端）主动进行TCP 连接，而子站（服务器端）被动响应TCP 连接；双方都使用固定的TCP 端口号2404；服务器端和客户端互知对方的IP 地址，作为判断连接的依据；当客户端没有进行数据请求而服务器端有数据变化时，服务器会主动上传变化数据。通过对陕京一线SCADA 系统应用Modbus 协议和IEC104 协议时业务数据流和数据响应时间进行比较和分析，总结并归纳了管道站场与调控中心之间应用基于IEC 104 协议的网络通信的优势：实时性好、可靠性高、数据流量大、便于信息量扩充、支持逢变则报、支持网络传输、数据带时间标签等。

Abstract:: During the consolidation of SCADA system for the 1st Shanxi-Beijing Gas Transmission Pipeline，IEC60870-5-104 protocol
based on TCP/IP has been applied to substitute the original communication mode of Modbus serial protocol.The key points
in IEC implementation is that IEC protocol between master and sub stations is based on the reliable TCP connection；the
TCP connection is initialized by the master station（client），and then accepted by the sub station（server）； the both sides use
the fixed 2404 TCP port the acknowledged IP addresses of the server and client are regarded as the basis for connection；
under the condition of no requests from the client but it is indeed changed in the server，the data will be sent initiatively by the
server.Based on the analysis of data flow and data response time in comparing the old station control system used Modbus
protocol to the reconstructed station control system used IEC 104 protocol，it is proposed that application of IEC 104 protocol
based on network between station and control center has such a great advantages such as real time，high reliability，large data
throughput，easy extension，report by exception，network transferring，data with timestamp，etc.
