[0002] At present, most of the vehicle-mounted LED display screens on the market are advertising information screens, such as the LED display screens on taxis, which are specifically used to play text and pictures.

[0003] However, there are many deficiencies in the application of general vehicle-mounted LED display screens to concrete transport vehicles. For example, Chinese patent No. CN113345352A discloses a vehicle-mounted LED display screen and its control system and control method, which include a screen body and an adjustment bracket; the screen body includes a PCB light board and transparent organic glass, and the front of the transparent organic glass is covered with a plurality of PCB light boards arranged in parallel. The advertising screen does not affect the rear window line of sight, and can display a variety of full-color videos and images, broadening the advertising content of taxi advertising screens and promoting industry development. The advertising screen is easy to install and adjustable, but there are also some problems: single function, For example, it can only display the playback content for people outside the car, and cannot form effective interaction with the driver; maintenance is inconvenient, for example, the content replacement process is cumbersome, the vehicle needs to be recalled, and cluster management cannot be achieved; the brightness of the LED screen cannot be controlled during the day and night, causing light pollution; the vehicle precise positioning function cannot be achieved, and most of the positioning terminals on the market are GPS positioning black boxes, which cannot display vehicle information and precise positioning; it cannot monitor the vehicle driving status, so as to analyze the driver's driving habits and supervise the driver's safe driving; it cannot be used as a vehicle control center and connected to other vehicle sensors, such as the mixing tank speed sensor for concrete transport vehicles. In view of this, it is particularly important to develop an intelligent display terminal for intelligent concrete transport vehicles to effectively improve the current management methods of concrete production enterprises.
