【摘要】 当前，牵引供电技术和运营管理技术的现代化是对电气化铁路的必然要求，微电子技术、计算机技术和网络通信技术的进步为铁路现代化的实现提供了条件，研制牵引变电所综合自动化系统和牵引供电运营管理信息系统正是应时所需。牵引变电所综合自动化系统、牵引供电运营管理信息系统及其之间的信息交换与处理在提高电气化铁路的运行和管理水平、转变设备维护与检修手段、减员增效等方面有着重要的作用。 对于信息交换而言，网络的拓扑结构和通信介质是非常重要的，直接决定着数据网络响应的实时性、通信的可靠性以及电磁兼容性等。因此，本文首先讨论了牵引变电所综合自动化系统的通信网络要求和网络结构以及综合自动化系统与管理信息系统信息交换的通信信道和网络结构。 其次，本文对牵引变电所综合自动化系统与牵引供电运营管理信息系统的交换信息内容进行了讨论并对各类信息的交换目的进行了阐述。 最后，本文对一个由两套牵引变电所综合自动化系统和一套牵引供电运营管理信息系统的通信子系统组成的实验系统完成了编程并进行了实验。在实验系统中，牵引变电所综合自动化系统内的通信管理装置利用嵌入式实时系统编程实现。通信管理装置具有承上启下的作用，主要完成3项功能：(1)按照传输规约IEC60870-5-103控制牵引变电所综合自动化系统中间隔层与变电所层的数据交换。(2)按照传输规约IEC60870-5-104完成综合自动化系统与管理信息系统的信息交换。(3)实现两种传输规约的相互转换。牵引供电运营管理信息系统的通信软件主要完成2项功能：(1)按照传输规约IEC60870-5-104完成与综合自动化系统的信息交换，通信协议为TCP/IP。(2)完成与管理信息系统中其它进程的通信，通信协议为UDP/IP。更多还原

【Abstract】 Nowadays, it is certainly demanded for the electrified railway to modernize traction power-supply technology and management technology. With the aid of the development of micro-electronic, computer and network communication technology, it is possible to use these technologies to improve the extent of automation and increase the speed of railway modernization. So it is opportune to develop the integrated automation system(IAS) for traction substation and the traction power-supply management information system(PSMIS). IAS, PSMIS and the information exchange and processing between these two systems have important effects on some aspects, such as the running and management ability of electrified railway, the maintaining and maintenance measures of electrical equipments, the economic efficiency of traction department, and so on.As to the information exchange, it is the network topology structure and the communication media that directly determine the performance of communication network, which include the response time, the security, the electromagnetism compatibility, and so on. So, the demand and the structure of the communication network in IAS are discussed firstly. Then the channel and the structure of the network from IAS to PSMIS are analyzed.Secondly, the communication information between IAS and PSMIS is discussed. And the different purposes of these information are discussed.Finally, some program and experiments are carried out for an experiment system consisted of two sets of IAS and one set of communication sub-system in PSMIS. In the experiment system, the embedded real-time system is used to realize the communication management device. The communication management device is a connecting link between the preceding and the following, which has three functions : (1) Controlling the data exchang between the middle layer and the substation layer of IAS in accordace with thetransmission protocol IEC60870-5-103. (2) Exchanging information between IAS and PSMIS in accordance with the transmission protocol IEC60870-5-104. (3) Transforming the two transmission protocols from one to another. The communication software in PSMIS has two functions: (1) Exchanging information with IAS in accordance with the transmission protocol IEC60870-5-104, which communication protocol is TCP/IP. (2) Communicating with other processes in PSMIS, which communication protocol is UDP/IP.更多还原
