The invention discloses a parking precision adjustment and control method of a full-automatic operation system. The parking precision adjustment and control method comprises the following steps: analyzing factors influencing the parking precision, wherein the factors comprise improper running-in of a vehicle brake shoe, unreasonable electro-pneumatic conversion parameters, unreasonable pneumatic braking parameters, uncertain additional resistance of a line, relatively large ATO measurement deceleration deviation and incomplete ATO control algorithm; brake shoe running-in tests are conducted on all the trains, electro-pneumatic conversion parameters and vehicle network management system parameters are adjusted, and the electro-pneumatic conversion starting speed and the electric braking quit delay time in the ATO mode are modified; the trains with poor braking performance are analyzed and processed, the braking performance of all the trains is kept consistent, the constant deceleration deviation of the trains under the fixed level is adjusted, air braking parameters are adjusted, the pre-pressure deceleration applying point is changed, and the air braking power value is modified in the electro-pneumatic hybrid process; and according to line condition differences of different stations, line additional resistance deceleration difference compensation is added, and an ATO control algorithm is optimized.

    一种全自动运行系统的停车精度调整与控制方法:分析影响停车精度的因素,包括车辆闸瓦磨合不到位、电空转换参数不合理、气制动参数不合理、线路附加阻力不确定、ATO测量减速度偏差较大和ATO控制算法不完备;对所有列车进行闸瓦磨合试验,调整电空转换参数和车辆网络管理系统参数,修改ATO模式下的电空转换起始速度和电制动退出延迟时间;分析处理制动性能较差的列车,使所有列车的制动性保持一致,调整列车固定级位下的恒定减速度偏差,调整气制动参数,更改预压力施减速度点,在电空混合过程修改气制动力值;根据不同站台的线路条件差异,增加线路附加阻力减速度差异性补偿,优化ATO控制算法。
