Abstract: The present disclosure relates to a passenger communication output control circuit for an unmanned metro train. The unmanned metro train is installed with passenger emergency communication units each having a communication button and a communication relay. The communication relay has a normally-closed contact pair and is linked with the communication button in a one-to-one correspondence. When the communication button is pushed down, the communication relay is energized to disconnect the normally-closed contact pair. The normally-closed contact pairs of all the coaches are connected in series to form an emergency communication circuit. Two terminals of the emergency communication circuit are respectively connected to a train power supply and an input/output module of a TCMS in the coach. When the passenger information system works normally, both a communication network and hardwire can transmitte the communication signal. When the two communication signals are inconsistent, the communication signal transmitted by hardwire shall prevail.

Abstract: A vehicle body contour-based derailment detection method for a rail vehicle, including: measuring distances between measuring points and rails through a range finder mounted on an underframe of a vehicle body, and calculating a transverse displacement of the current vehicle body in a vehicle body coordinate system; measuring an inclination angle of the current vehicle body in the vehicle body coordinate system through an inclination sensor on the vehicle body; with reference to a size of the vehicle body and distribution positions of the measuring points, as well as the transverse displacement of the current vehicle body in the vehicle body coordinate system and the inclination angle of the vehicle body in the vehicle body coordinate system, obtaining a dynamic outer contour of the vehicle body in the vehicle body coordinate system and converting it into a dynamic outer contour in the rail coordinate system.
