Automatic control system of vehicle lamps facing tunnel

Abstract

The invention discloses an automatic control system of vehicle lamps facing a tunnel. The automatic control system comprises an upper computer, a tunnel terminal and a vehicle-mounted terminal, wherein the upper computer is used for storing the position coordinate range of a road section where the tunnel is positioned, comparing the current vehicle position coordinate reported by a wireless transmission module with the position coordinate range, and feeding a result back to the wireless transmission module; the tunnel terminal comprises a first signal transmitting module and a second signal transmitting module; the vehicle-mounted terminal comprises a GPS locating module, a control module, the wireless transmission module, a trigger module, a light control module and a signal receiving module; the control module is further used for generating a second control signal according to the comparison result, and transmitting the second control signal to the light control module through the trigger module to enable the light control module to enter a working state; when the signal receiving module receives a transmitting signal of the first signal transmitting module, the light control module controls the vehicle lamps to be turned off; and when the signal receiving module receives a transmitting signal of the second signal transmitting module, the light control module controls the vehicle lamps to be turned on. According to the automatic control system, the vehicles entering the tunnel can be controlled in real time, turning on and turning off of the vehicle lamps are automatically achieved, and the energy consumption is reduced.
