Discussion on the Reliability of Railway Signal Lighting Units
The signal display of ordinary-speed railways still depends on ground signals in China,and whether sig-nals can work normally directly affects traffic safety and transportation efficiency.In order to ensure the reliable work of railway signals,it is necessary to have stable and reliable signal light sources,and the lighting unit is the core part of signal light sources.In view of the low reliability of railway signal lighting units at present,through careful analy-sis,this paper discusses and improves the selection of filament conversion devices and the driving principle of fila-ment conversion relays,and proproses to use carrier communication to provide reliable power supply for the moni-toring unit,which improves the reliability of signal lighting units and provides technical guarantee for the realization of the"fault repair"of railway signal lighting units.
