The invention discloses a truck instrument reversing video image implementation system, belongs to the technical field of reversing images, and aims to solve the problem that an existing truck instrument does not have a reversing video image function. The device comprises an analog signal access interface for receiving analog signals of baseband videos, and transmitting the analog signals to a video decoding module after voltage division and LC filtering; the video decoding module is used for analyzing the analog signal into a digital signal according to the digital signal format configured by the main controller module and transmitting the digital signal to the interface conversion module; the interface conversion module is used for receiving a video/screen switching signal of the main controller module, displaying a digital signal transmitted by the video decoding module on a liquid crystal screen when receiving a video signal, and displaying an instrument main interface on the liquid crystal screen when receiving a screen signal; and the main controller module is used for configuring the format of the digital signal output by the video decoding module and outputting a video/screen switching signal to the interface conversion module. The method is used for displaying the back-up image and the instrument interface.
