The embodiment of the invention relates to an overspeed protection control method for a train network control system. The method comprises the following steps: S1, generating a current speed limit value, a critical speed limit value and a maximum speed limit value according to a current operating condition state symbol; S2, collecting a real-time vehicle speed, a real-time handle instruction and areal-time handle level; S3, turning to step S2 if the real-time vehicle speed is smaller than the critical speed limit value, and turning to step S4 otherwise; S4, executing resection traction overspeed protection control; S5, collecting a real-time vehicle speed, a real-time handle instruction and a real-time handle level; S6, turning to the step S2 if the real-time vehicle speed is smaller thanthe critical speed limit value, and turning to step S7 otherwise; S7, turning to the step S4 if the real-time vehicle speed is smaller than the current speed limit value, and turning to step S8 otherwise; S8, executing active braking overspeed protection control according to the real-time handle instruction, the real-time handle level, the real-time vehicle speed, the current speed limit value and the maximum speed limit value; S9, collecting a real-time vehicle speed; S10, turning to the step S7 if the real-time vehicle speed is smaller than the current speed limit value, and turning to stepS11 otherwise; and S11, executing emergency braking overspeed protection control.

    本发明实施例涉及一种列车网络控制系统超速防护控制方法,所述方法包括:S1根据当前运行工况状态符生成当前限速值、临界限速值、最大限速值;S2采集实时车速、实时手柄指令和实时手柄级位;S3实时车速小于临界限速值转S2反之转S4;S4执行切除牵引超速防护控制;S5采集实时车速、实时手柄指令和实时手柄级位;S6实时车速小于临界限速值转S2反之转S7;S7实时车速小于当前限速值转S4反之转S8;S8根据实时手柄指令、实时手柄级位、实时车速、当前限速值和最大限速值执行主动制动超速防护控制;S9采集实时车速;S10实时车速小于当前限速值转S7反之转S11;S11执行紧急制动超速防护控制。
