The invention discloses a method for adjusting the service brake pressure reduction amount of a rail transit engineering vehicle operation protection system, which comprises the following steps of: when service brake is output, judging a marshalling wind receiving state in real time, acquiring and judging a train pipe pressure value of an engineering vehicle in real time, and when the marshalling state and the wind receiving number are not zero, judging the pressure value of a train pipe of the engineering vehicle; in the service braking process, the pressure reduction time is calculated according to the existing pressure reduction coefficient, after pressure reduction is completed, the actual pressure reduction amount and the target pressure reduction amount are compared and judged, the actual pressure reduction coefficient of the engineering truck line is calculated, and the additional pressure reduction time is calculated according to the actual pressure reduction coefficient and the difference value between the actual pressure reduction amount and the target pressure reduction amount. And finally, secondary pressure reduction is carried out on the system according to the additional pressure reduction time, so that the safety and the usability in the marshalling operation process of the urban rail transit engineering vehicle operation protection system are improved.
本发明公开了一种轨道交通工程车运行防护系统的常用制动减压量调整方法，在输出常用制动时，对编组接风状态进行实时判断，并对工程车列车管压力值进行实时采集判断，在编组状态且接风辆数不为零时，常用制动过程中先按照既有的减压系数计算减压时间，减压完成后对实际减压量和目标减压量进行对比判断，并计算工程车列实际减压系数，并根据实际减压系数和实际减压量与目标减压量的差值计算出追加减压时间，最终按照追加减压时间对系统实施二次减压，提高了城市轨道交通工程车运行防护系统编组作业过程中的安全性和可用性。
