Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, the fault detection device for the rail transit vehicle lighting system comprises a vehicle power supply U0, a first power supply U1, a second power supply U2, a relay, a lamp E, a light sensor G and a vehicle control system T. The vehicle control system T is provided with a first voltage detection end A, a second voltage detection end B and a third detection end C. The relay includes a coil end KM and a normally closed contact end KM 1. The vehicle control system T is also provided with a display device (not shown in the figure).

The output end of the vehicle power supply U0 is connected with the input end of the first power supply U1, and the output end of the first power supply U1 is connected with the input end of the vehicle lamp E. The first voltage detection end A is connected with the output end of the vehicle power supply U0, the second voltage detection end B is connected with the output end of the first power supply U1, and the third voltage detection end C is connected with the light sensor G; the light sensor G is positioned in the illumination range of the car lamp E. The output end of the second power supply U2 is connected with the input end of the car lamp E through the normally closed contact end KM 1. The coil end KM is connected to the first voltage detection end a and the second voltage detection end B. In the embodiment, the light sensor is of a current type, the model is UCS31061, and the model of the relay is F470-DD 4V.

Under normal conditions, VA is more than or equal to 77V and less than or equal to 137.5V, and the vehicle power supply U0 works normally. VB is more than or equal to 16.8V and less than or equal to 30V, and the first power supply U1 works normally. IC is less than or equal to 16mA, and the vehicle lamp E works normally. At this time, the coil end KM is in an energized state, the normally closed contact end KM1 is in an open state, and the second power supply U2 is disconnected and is in a standby state. VA is a voltage value detected by the first voltage detection terminal, VB is a voltage value detected by the second voltage detection terminal, and IC is a current value detected by the third voltage detection terminal.

When the vehicle control system T (TCMS) receives that VA, VB or IC are not in the corresponding working voltage or current interval, the detection signal is considered to be abnormal. When the detection signals received by the vehicle control system T (TCMS) are abnormal, the fault point can be identified by identifying the detection port corresponding to the abnormal data, so that the fault point is quickly positioned, and the fault states of the three detection ends are synchronously displayed on the display equipment.
