摘　　要：从速度防护曲线生成的角度研究列车超速防护算法。根据静态限速和临时限速等,合成最严格限速曲线。分析了单限速区速度防护曲线的算法,针对多限速区,通过递推算法,完成了分级速度控制与目标速度控制模式的结合;实现了司机驾驶模式和自动驾驶模式下,CTCS-3级列车运行控制系统的超速防护。使用该仿真系统对郑西线线路数据进行运行仿真,验证了该速度防护算法的有效性,并为以后进行列车速度防护的研究提供了可靠的实验环境。We studied the Automatic Train Protection System in the view of generating the speed protec- tion curve. The synthesis of the most strict speed restriction curve was based on the static speed restric- tion and the temporary speed restriction. The speed protection curve of single speed restriction section was studied and recursive algorithm was proposed to combine the graded speed control and target velocity con- trol mode for multiple speed restriction section. Under both the modes of automatic driving and manual operation, an Automatic Train Protection of CTCS-3 Train Control System was realized. This simulation system verified the effectiveness of the speed protection algorithm by using the data from the Zhengzhou - Xihn railway line and provided an reliable experimental environment for further research on Train Protec- tion.
