状态转换图是为了在动车组仿真系统中实现全自动模拟驾驶功能。本转换图以中国铁道科学研究院集团有限公司机车车辆研究所(简称:铁科院机辆所)开发的高速动车组仿真系统软件为基础,基于高速动车组仿真系统配置参数,并结合动牵引计算规程,来实现动车组自动驾驶的功能。在自动驾驶过程中,程序根据状态转换图中的状态,决定控制动车组运行的手柄位置,实现全自动的模拟司机驾驶动车组。通过软件仿真,证明该算法切实可靠,能够保证动车组按照预定的加减速方式,实现全程自动驾驶,能够精准停站,并防止超速。

The purpose of the state transition diagram proposed in this paper was to implement the full automatic driving simulation function in the EMU simulation system.The transition diagram was based on the simulation system software of the high-speed EMU developed by the Locomotive&Car Research Institute of China Academy of Railway Sciences Corporation Limited.Based on the configuration parameters of high-speed EMU simulation system and combined with the calculation rules of traction,the automatic driving function of EMU was implemented.In the process of automatic driving,according to the state in the state transition diagram,the program decided the position of the control handle to control the operation of the EMU,and implemented the full-automatic simulation of the driver driving the EMU.Through software simulation,the algorithm is proved practical and reliable.It can ensure that the EMU can drive automatically in the whole journey according to the scheduled acceleration and deceleration mode,stop accurately and prevent over-speed.
