A Study on the Train Plan Transmission Scheme of Intelligent High-Speed Railway based on ATO

在智能高速铁路系统中,CTC系统向车载ATO设备下达智能高速铁路ATO列车计划,实现对列车的自动控制,提高列车自动驾驶的准点率,降低列车运行能耗。分析智能高速铁路ATO列车计划的传输途径,明确ATO列车计划的数据类型。通过阐述前方车站判断、站车计划一致性保持2项智能高速铁路ATO列车计划传输关键技术,制订完整的ATO列车计划传输流程,分为计划生成、计划发送、计划更新、计划完成4部分。该智能高速铁路ATO列车计划传输方案已经实际应用于京张智能高速铁路系统中,经过实践检验,可以确保ATO列车计划内容发送的准确性与实时性。

For the intelligent high-speed railway system,the CTC system provides the ATO train plan to the onboard ATO equipment to help realize automatic control of the train,which increases the automatic driving punctuality rate and reduces operation energy consumption.This paper clarifies the data type of the ATO train plan by analyzing the transmission way of ATO train plan for intelligent high-speed railway.By elaborating two technical key points such as the judgment of the station in front of the ATO train,the dynamic maintenance and the consistency of the station plan,the complete ATO train plan transmission process is proposed,which is mainly divided into four parts:generation,transmission,update,and completion of the plan.Since this intelligent highspeed railway ATO train plan transmission scheme has been used in the Beijing-Zhangjiakou smart high-speed railway system,it has been verified by actual tests to ensure the accuracy and realtime of ATO train plan.
