The invention provides a hydraulic braking system throttle valve fault judgment method and device. The method is applied to a hydraulic braking system, and comprises: obtaining the motor state information of a motor; judging whether the motor is in a starting state or not based on the motor state information; when the motor is in a starting state, sampling oil pressure of an energy accumulator inthe hydraulic braking system based on a preset period, and calculating the oil pressure rising rate of the oil pressure of the energy accumulator in the current period based on a sampling result; judging whether the oil pressure rising rate is greater than a first preset oil pressure rising rate or not; when the oil pressure rising rate is greater than a first preset oil pressure rising rate, controlling a first counter to add 1 to a counting result; whether the counting result of the first counter is larger than a first preset value or not is judged, if yes, outputting first prompt information used for representing that the throttle valve of the energy accumulator is abnormal, and guaranteeing safe and reliable operation of a train.
本发明提供一种液压制动系统节流阀故障判断方法和装置,方法应用于液压制动系统中,包括:获取电机的电机状态信息;基于所述电机状态信息判断所述电机是否处于启动状态;当所述电机处于启动状态时,基于预设周期对所述液压制动系统中蓄能器油压进行采样,基于采样结果计算得到当前周期内蓄能器油压的油压上升速率;判断所述油压上升速率是否大于第一预设油压上升速率;当所述油压上升速率大于第一预设油压上升速率时,控制第一计数器计数结果加1;判断所述第一计数器的计数结果是否大于第一预设值,如果是,输出用于表征蓄能器节流阀异常的第一提示信息,保证了列车安全可靠运行。
