The invention relates to a train air tightness test data analysis and early warning system and method.The train air tightness test data analysis and early warning system comprises an outside-train air tightness test part and an inside-train air tightness monitoring part which are arranged on a train in advance before an air tightness test, and the outside-train air tightness test part is detached after the air tightness test is finished; the outside-vehicle air tightness test part comprises an outside-vehicle system control host, an equipment fan and a plurality of external air pressure detection devices; the outside-vehicle system control host is used for analyzing the position of a vehicle leakage point during an air tightness test; the in-train air tightness monitoring part comprises an in-train data monitoring host, a train control unit, a passenger information host and a plurality of built-in air pressure detection devices. The in-train data monitoring host is used for early warning of air tightness attenuation in carriages in the train running process. According to the invention, the danger in the test process can be reduced, the air tightness data of the typical position of the compartment can be monitored, and early warning can be given out for the problem of poor air tightness possibly occurring in the future, so that the running safety of the train is ensured.
本发明涉及一种列车气密性试验数据分析及预警系统、方法,包括车外气密性试验部分和车内气密性监控部分,二者在气密性试验前提前布置在列车上,并且在气密性试验结束后拆除车外气密性试验部分;车外气密性试验部分包括车外系统控制主机、设备风机和若干个外接气压检测装置,车外系统控制主机用于在气密性试验时分析出车辆泄漏点位置;车内气密性监控部分包括车内数据监控主机、列车控制单元、旅客信息主机和若干个内置气压检测装置,车内数据监控主机用于在列车运行过程中对车厢内气密性衰减进行预警。本发明可降低试验过程中的危险性,也可对车厢典型位置气密性数据进行监控,对未来可能出现的气密性不良问题发出预警,从而保证列车运行安全。
