The invention relates to a lighting feedback system for headlamps for railway vehicles. The lighting feedback system comprises state monitoring modules, wherein each state monitoring module comprises a filter, a relay protection device, an input voltage and current sampling module, two relays and an indicating lamp, the filter, the relay protection device and a ballast are sequentially connected in series, a bulb is connected with the ballast, the input voltage and current sampling module acquires output voltage and output current of the filter, a coil of one relay and the indicating lamp are connected with the input voltage and current sampling module, and a coil of the other relay is connected with the input voltage of the filter. With the adoption of the lighting feedback system for the headlamps for the railway vehicles, the relays are controlled by the input voltage and current sampling modules to finish feedback together, one relay is additionally arranged to feed back the input voltage state of the bulbs, the feedback line structure is simple, feedback is timely and reliable, feedback signals are low-current feedback signals, and the system is suitable for popularization and usage.
Description
technical field [0001] The invention relates to a lighting system of a rail vehicle, in particular to a headlight lighting feedback system for a rail vehicle. Background technique [0002] The headlights of high-speed EMU trains include dipped beams, high beams and indicator lights. In order to ensure the normality of the vehicle lighting system, if the low beam and high beam fail during operation, the indicator light on the console of the driver's cab will report the failure. At the same time, after a fault occurs, the lighting feedback system will also feed back the status of the headlights to the control system. However, the original lighting feedback system is relatively complicated, and the feedback information is not timely and reliable enough. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the problems that the original lighting feedback system is complex and the feedback information is not t...
