The invention discloses a railway vehicle and a dynamic air tightness monitoring system and method. The system comprises an in-vehicle pressure data acquisition unit and a data processing and control unit. Each section of vehicle is provided with an in-vehicle pressure data acquisition unit, and the in-vehicle pressure data acquisition unit of each section of vehicle is connected with the data processing and control unit; the data processing and control unit is used for calculating a first pressure change amplitude in a first time period and/or a second time period according to the in-vehicle pressure real-time value of each section of vehicle; and controlling a corresponding in-vehicle air pressure adjusting device to act according to the first pressure change amplitude and the first standard change amplitude. Real-time monitoring of the dynamic air tightness of the train is achieved, the in-train air pressure adjusting device is adjusted according to the in-train pressure real-time value collected in real time, the in-train pressure is adjusted in real time, and the riding comfort of passengers is improved.

    本发明公开了一种轨道车辆及动态气密性监控系统、方法,所述系统包括车内压力数据采集单元以及数据处理与控制单元;在每节车均设有车内压力数据采集单元,每节车的车内压力数据采集单元均与数据处理与控制单元连接;数据处理与控制单元用于根据每节车的车内压力实时值计算出第一时间段和/或第二时间段内的第一压力变化幅值;根据第一压力变化幅值和第一标准变化幅值控制对应的车内气压调整装置动作。本发明不仅实现了列车动态气密性的实时监控,还根据实时采集的车内压力实时值调节车内气压调整装置,实现了车内压力的即时调节,提高了乘客的乘坐舒适性。
