Abstract

The invention relates to a rail transit emergency lighting control circuit which comprises an emergency lighting control train line penetrating through a whole vehicle, a time delay module located on a head vehicle and a head vehicle contactor controlled by the time delay module, and the end of the emergency lighting control train line is connected with an emergency power supply of the head vehicle through a first normally open contact of the head vehicle contactor. A second normally open contact of the head car contactor is connected in series with a power supply loop of the head car emergency lighting lamp; the middle train is provided with a middle train contactor connected to an emergency lighting control train line, and a normally open contact of the middle train contactor is connected into a power supply loop of a middle train emergency lighting lamp in series. Every two adjacent vehicles are grouped, and the emergency lighting lamps are connected through the emergency lighting redundant train lines. A pairwise redundant power supply mode is adopted for vehicle emergency lighting power supply, the function of emergency lighting time delay after the whole train is dormant is achieved through an adjustable time delay relay, and the function of short circuit and overload isolation of a downstream control circuit is achieved by additionally arranging a circuit breaker.

Description

Technical field [0001] The present invention relates to a rail vehicle emergency lighting control circuit, belonging to the technical field of emergency lighting rail vehicle. Background technique [0002] Conventional emergency lighting control circuit can not meet emergency vehicle lighting driverless metro Emergency lighting power supply circuit redundancy and sleep latency requirements of the vehicle, and therefore need to design a power supply circuit redundant emergency lighting and emergency lighting delay control circuit, to meet the requirements of the unmanned vehicle. Inventive content [0003] The main object of the present invention is directed to above-mentioned drawbacks of the prior art, there is provided a rail emergency lighting control circuit, the redundant power supply emergency lighting and emergency lighting delay. [0004] To solve the above technical problem, the emergency lighting rail of the present invention provides a control circuit comprising an em...
