基于通信的列车控制（CBTC）系统是一种利用车地双向通信确保轨道车辆安全运行的自动化列车控制系统。 CBTC 系统对通信可用性和延迟有严格的要求。由于无线通信不可靠和频繁切换，现有的CBTC系统会严重影响列车控制性能、列车运行效率和铁路的利用率。在本文中，我们利用协调多点传输和接收 (CoMP) 的最新进展来增强 CBTC 系统的列车控制性能。通过 CoMP，列车可以同时与一组基站 (BS) 通信，这与当前的 CBTC 系统不同，在当前的 CBTC 系统中，列车在任何给定时间只能与单个 BS 通信。此外，与现有的 CoMP 工作不同，本文将 CBTC 系统中列车控制性能的线性二次成本视为性能度量。我们共同考虑CBTC系统中的BS集群选择和切换决策问题。此外，为了减轻通信延迟对列控性能的影响，我们在列控过程中提出了一种充分考虑切换延迟引起的跟踪误差的最优引导轨迹计算方案。仿真结果表明，我们提出的采用 CoMP 的 CBTC 系统可以显着提高列车控制性能。
A communication-based train control (CBTC) system is an automated train control system that uses bidirectional train-ground communications to ensure the safe operation of rail vehicles. CBTC systems have stringent requirements for communication availability and latency. Due to unreliable wireless communications and frequent handoffs, existing CBTC systems can severely affect train control performance, train operation efficiency, and the utility of railways. In this paper, we use recent advances in coordinated multipoint transmission and reception (CoMP) to enhance the train control performance of CBTC systems. With CoMP, a train can communicate with a cluster of base stations (BSs) simultaneously, which is different from the current CBTC systems, where a train can only communicate with a single BS at any given time. In addition, unlike the existing works on CoMP, in this paper, the linear quadratic cost for the train control performance in CBTC systems is considered the performance measure. We jointly consider the BS cluster selection and handoff decision issues in CBTC systems. Moreover, in order to mitigate the impacts of communication latency on train control performance, we propose an optimal guidance trajectory calculation scheme in the train control procedure that takes full consideration of the tracking error caused by handoff latency. Simulation results show that train control performance can be substantially improved in our proposed CBTC system with CoMP.
