Abstract: This paper introduces the system composition, system functions and main characteristics of the autonomous train operation system. Based on resource management and characterized by active train routing and autonomous train protection, the current train onboard equipment confirms the positions and running direction of trains on the route according to the position information of the trains, requests the position and speed information from the preceding train in operation, and requests for the required trackside resource information from the trackside resource management equipment. The preceding train periodically sends real-time position information and resource occupancy/release information to the current train, and the current train calculates its movement authority in real time and updates its speed control curve, to shorten the system's headway. The proposed system utilizes active perception devices to identify obstacles ahead, signal status ahead, and position information about the preceding train, achieving reliable operation in degraded mode.

Key words: Train Autonomous Circumambulate System (TACS), resource management, movement authority, headway, speed curve

摘要： 介绍列车自主运行系统的系统组成、系统功能及主要特点。以资源管理为基础，以列车主动进路、列车自主防护为特征，当前列车车载设备根据列车的位置信息确认线路中列车的位置及运行方向，向运行的前车请求其位置及速度信息，并向轨旁资源管理设备申请所需的轨旁资源信息。前车周期性地向当前列车发送实时位置信息和资源占用/释放信息。当前列车实时计算移动授权并更新其速度控制曲线，提高系统的行车间隔。系统借助主动感知设备识别前方障碍物、前方信号机状态、前车列车的位置信息等，实现降级模式的可靠运行。
