研究目的:随着国务院批准的《中长期铁路网规划》的实施,电气化铁道牵引供电远动系统将得到更广泛的应用,在设计中,如何选择设计合理的牵引供电远动系统的重要组成部分———电气化铁路远动通道。研究方法:分析主控站和被控站设备对通道的要求及接口方案,以及国内电气化铁路的通信网络建设现状,结合近几年国内通信领域日益兴起的MSTP(综合业务传输平台)技术,进行研究。研究结果:给出了电气化铁路远动通道组成方案的建议意见,并预测了电气化铁路远动通道的发展趋势。研究结论:(1)远动通道:当被控站较多、尤其是占用长途通道较多时,建议以调度台为单位组成2 Mbps自愈环网、采用2M E1接口,控制站及被控站均加设路由器、IP寻址方式,若考虑路由器也有备用,则组2个2 Mbps自愈环网;当被控站较少、基本上不占用长途通道时,可采用一主一备的64 k点对点方式,采用64 k4线音频板、同步/异步RS232/RS422/RS485接口。(2)视频通道:当被控站较多时,采用以调度台为单位组成2 Mbps自愈环网;当被控站较少、仅为增加个别被控站时,通过经济比较,也可采用2 Mbps点对点方式。(3)近几年国内通信领域日益兴起的MSTP(综合业务传输平台)技术应成为电气化铁路专网建设的首选,应很好的整合被控站内的综自系统、视频监控、MIS等传输网络,从而实现一种网络提供多种业务平台。
Research purposes: With the implementation of the “Medium and Long-term Railway Network Planning” approved by the State Council, the electrified railway traction power supply and telecontrol system will be more widely used. In the design, how to choose an important part of the well-designed traction and power supply telecontrol system --- Electrified railway telecontrol channel. Research Methods: This paper analyzes the requirements and interface schemes of the main control station and the controlled station equipment for the channel as well as the status quo of the communication network construction of the domestic electrified railway. In combination with the MSTP (Integrated Services Transport Platform) technology that is increasingly emerging in the domestic communications field in recent years, the study. Findings: The suggestions for the composition of the telecontrol channel for the electrified railway are given, and the development trend of the telecontrol channel for the electrified railway is predicted. Research conclusions: (1) Telecontrol channel: When there are more controlled stations, especially long-haul routes, it is suggested to construct a 2 Mbps self-healing ring network by using the dispatching station as a unit, with 2M E1 interface, control station and charged station Add a router, IP addressing mode, if you consider the router is also standby, the group 2 2 Mbps self-healing ring network; when the charged station is less, basically do not take long-distance channel, you can use a master-backup 64 k point-to-point mode, with 64 k4 audio board, synchronous / asynchronous RS232 / RS422 / RS485 interface. (2) Video channel: When more stations are controlled, a 2 Mbps self-healing ring network is formed by using dispatching stations. When there are fewer charged stations, only by adding individual controlled stations, economic comparison can also be adopted 2 Mbps point-to-point mode. (3) In recent years, the MSTP (Integrated Services Transport Platform) technology that is increasingly emerging in the field of communications in the country should become the first choice for the construction of a private railway network for electric railway. The transport network such as self-contained systems, video surveillance, MIS and so on, , In order to achieve a network to provide a variety of business platforms.
