| Abstract: | Through a tracking test of the speed sensor working state during the operation of an urban rail transit vehicle in neutral zone,the potential fluctuation at the axle end of the car body,the fluctuation of speed sensor power supply voltage,and the fluctuation of speed sensor output signal during different operations of opening and closing are analyzed.In this way,causes of signal false alarm of speed signal sensors and other equipment during different operations of opening and closing when a rail transit vehicle stops in the neutral zone are detected,corresponding solutions are proposed. |
