In order to solve the problems such as undetected errors in the manual inspection widely used in train air pressure detection,this essay discusses and designs a new type of Portable Train Air Pressure Monitor System,which actualizes data exchange between Mobile Air Pressure Monitor Instruments and Data Center using wireless data transceiver TDX-2000.The practical use shows that the system functions stably,with the relative error rate rising from 5% at manual measuring to 0.1% and the reliability of leakage detecting reaching 98%,thus decreases the safety hidden trouble brought by manual detecting. 风压监测 无线通信 串口复用 air pressure monitor wireless communication universal asynchronous receiver transmitter multiplexing TP274.4 湖北省科技攻关项目资助（2003AA101C23） 2005-05-01 2021-04-01 5
