摘　　要：智能化驾驶系统是重载铁路的未来发展方向,而保障列车安全的列车运行控制系统是智能驾驶系统的基础,无线闭塞中心作为列车运行控制系统的地面核心设备,也必须针对重载铁路的需求进行研发。文章提出一种无线闭塞中心,其根据重载铁路智能驾驶系统的特点,在既有高速铁路无线闭塞中心的基础上对无线通信、列车定位、行车许可、临时限速等核心功能进行了改进,增加了与LKJ装置(简称“LKJ”)的车地无线通信接口,使得地面设备可以向LKJ实时发送控车命令;采用LTE网络替代GSM-R网络以得到更高的带宽,从而能够以更高的频率进行车地通信,以适应移动闭塞的需求;采用基于北斗卫星定位的虚拟应答器技术,不仅节约了成本,而且避免了高铁列车定位中有歧义情形的发生;可以通过配置选择不同的闭塞制式,同时支持准移动闭塞和移动闭塞的功能;为了能在下发临时限速命令的同时即时地配合司机既有的驾驶习惯,采用了当前重载列车临时限速命令的格式并通过无线消息下发给车载LKJ,此外还增加了调车防护功能。目前,该设备作为“神华号”机车智能驾驶系统的地面列控子系统已经被成功应用于神朔重载铁路,智能驾驶系统的控车率超过90%,每日可多开行5~6列万吨重载列车,成为提高重载铁路运营效率的重要支撑。Intelligent driving system is the development direction of heavy haul railway, automatic train protection(ATP)system to ensure the safety of train is the basis of intelligent driving system and radio block center(RBC) is the wayside ATP core equipment used in high speed railway. Different from the existing RBC, this paper proposes a new type of RBC which aims at heavy haul railway. Based on the characteristics of the heavy haul railway intelligent system, the RBC core functions such as radio communication, train location, movement authority, temporary speed restriction, etc. are improved. Wireless interface with LKJ is added, so the control command can be sent from wayside to LKJ instantly;LTE wireless network is used for onboard-wayside communication to replace GSM-R in order to adapt to the requirement of moving block which need higher frequency communication session;virtual balise technology based on Beidou GNSS is used for train location, which can save cost and avoid ambiguous train position;configuration function is used for switching between fixed block and moving block;temporary speed restriction command is issued based on the format of LKJ to adaption the custom of drivers;and a new function called shunting protection is added. The RBC has been successfully applied to Shenhua locomotive intelligent driving system, its vehicle control rate is more than 90% and the number of operated heavy haul railway trains is 5~6 more than normal, which helps improve the operation efficiency of Shenshuo heavy haul railway.
