重载铁路列控系统应答器布置方法

Balise Layout Method for Train Control System of Heavy Haul Railway

以重载铁路四显示自动闭塞线路为基础,考虑重载列车长度不固定、机车制动参数差异、机车控制设备切换等因素,研究重载铁路列控系统的应答器布置方法。分别根据区间应答器、出站应答器、连接应答器、预告应答器、执行应答器、注销应答器的不同应用要求,分析应答器布置过程中需满足的技术条件,建立满足重载铁路列控系统的应答器布置模型。与CBTC系统以及CTCS-2/3级列控系统应答器布置方法相比,该模型能够根据自身限制条件给出有效的应答器布置方案,以供设计人员参考。通过开发相关软件,结合准池线路实际工程应用,验证了应答器布置方案的可行性与高效性。

Considering factors such as unfixed length of heavy haul train,difference in locomotive braking parameters and switching of locomotive control equipment,this paper studies the balise layout method of train control system based on the four-aspect automatic block line of heavy haul railway.In line with the different application requirements of section balise,outbound balise,connecting balise,warning balise,execution balise and cancellation balise respectively,this paper analyzes the technical conditions that need to be met during balise layout and establishes a balise layout model applicable to the train control system of heavy haul railway.Compared with the balise layout methods of CBTC system and CTCS-2/3 train control system,the model can produce an effective balise layout scheme according to its own constraints for designers' reference.The feasibility and efficiency of the balise layout scheme are verified by developing relevant software and in combination with the actual engineering application of Zhunchi Railway.
