Research of Automatic Switching Device for the Headlights of High-speed Electric Multiple Unit Entering and Exiting Tunnels
In this paper,aiming at the problems that there are many tunnels in mountain high-speed railway running in the daytime,the drivers need to switch the headlights frequently to enter and exit tunnels,which causes a great burden and a certain labor intensity,an automatic switching device is developed for the headlights of high-speed electric multiple units entering and exiting tunnels.Photosensitive resistance sensor automatically controls the turning on and turning off the headlights of high-speed electric multiple units by single-chip microcomputer,according to the different light brightness inside and outside the tunnels,so as to reduce the working intensity of high-speed electric multiple unit drivers,and to achieve the purpose of high-speed rail transport safety.
