The invention discloses a novel urban rail traffic guidance communication system. The novel urban rail traffic guidance communication system comprises shells, a monitoring device, power generating devices and a self-cleaning device, wherein the shells comprise the first shell and the second shell, a water storage tank of the self-cleaning device is fixedly connected with the rear end of the upperside face of the first shell, four cylindrical cavities uniformly distributed in an annular shape in the bottom side of the second shell are internally and fixedly connected with the power generatingdevices, the power generating devices are in transmission connection with wind wheels, the upper sides of the power generating devices are provided with a data processing device, and the data processing device is fixedly connected with the monitoring device. The novel urban rail traffic guidance communication system has the advantages that the power generating devices utilize the wind energy and adopt dual-rotor three-coil structures, so that the power generating efficiency is improved, and a part of electric energy is provided for the system; after first coils are energized, the electromagnetic repulsion between first iron cores and sucking discs and the elastic force of springs support the data processing device, so that the damping effect is good; a sealing ring at the upper end of thesecond shell body prevents rainwater from entering the monitoring device, and the self-cleaning device periodically cleans the surface of the monitoring device to ensure that the working portion of the surface of the monitoring device is clean.
