Tunnel positioning device

The invention relates to a tunnel positioning device, which comprises a plurality of groups of positioning scanning structures and an integrated wire harness, and is characterized in that the plurality of groups of positioning scanning structures are arranged at equal intervals and are connected to the integrated wire harness; the positioning scanning structure is composed of an outer shell, a scanning light source structure, a light source induction structure, a signal receiving antenna and a signal transmitting antenna. A signal receiver, a signal transmitter, a modulation-demodulation integrated controller, a light source controller, a central controller, a built-in power supply and a wiring sliding plug-in unit are arranged in the outer shell. The tunnel positioning setting is optimized, the traditional positioning mode is changed, the tunnel positioner connected with the vehicles in the tunnel is designed, the infrared light sources are used for detecting whether the vehicles exist in the current area or
