Abstract: The new balise can achieve function extension on the basis of the existing balise. This paper studies how to achieve train-to-wayside communication, automatic tracking of train front and rear end locations, train section and track occupancy detection as well train integrity detection while retaining the existing functions. The new balise simplifies the equipment types of signaling system, reduces the quantity of wayside equipment, and lowers construction and maintenance costs. It can either form part of a low-cost and efficient intermittent signaling system or serve as the backup mode of a CBTC system, and can ensure real-time emergency response through low-cost wireless communication methods.

Key words: train location tracking, occupancy detection, equipment type simplification of train control system

摘要： 新型应答器系统可在现有应答器基础上进行功能扩展，研究在保留现有功能的基础上实现车到地通信、列车首尾位置追踪、列车分区和股道占用检查、列车完整性检查等，简化信号系统设备种类，降低建设和维护成本。可基于新型应答器构成低成本高效的点式信号系统、或作为CBTC的后备模式，能够通过低成本无线通信保障应急突发事件的实时响应。
