The function keys 31 correspond to selection of different functions, such as data retrieval, storage, downloading, or navigation enabling, among others, the functions mentioned in this description. The USB data interface 33 may download the locally stored data.

fig. 5 is a schematic structural diagram of a display screen in the novel multifunctional intelligent visual system for a semitrailer, provided by the invention, wherein the display screen is a high-definition large flat screen, can simultaneously display 4-way photography, and can also display navigation or other special functions according to the operation of a driver. The display screen comprises a touch area 41, and a setting key 42, a confirmation key 43, a left key 44, a right key 44, a home key 45 and a power supply 46 are sequentially arranged below the touch area 41. The setting key 42 can call up a display screen setting menu, and the home key 45 can make a display key of the display screen return to a main page of the functional page.

When the host and the display screen are started, the video monitoring picture shown in fig. 6 can be automatically displayed on the display screen, and pictures of 360 degrees around the vehicle are transmitted back by the 4-way camera and are simultaneously displayed on the screen. Double clicking any one split screen with a finger zooms in the split screen to full screen. The function page conversion as shown in fig. 7 can be realized by dragging the screen left and right by pressing a finger, and the function page can also be switched by left and right keys below the display screen.

The function pages can be switched left and right as shown in fig. 6, 3 function pages are developed temporarily, and new pages can be added on two sides if other functions are loaded in the later period.

the video monitoring function page is an intermediate page, 4-way images shown in fig. 5 are displayed after the system is started, and the home key returns by one key. But the relevant screen is intelligently displayed if the vehicle enters the reverse or turns (as shown in fig. 7). When the vehicle turns forwards, no matter what function page or setting menu the vehicle is in, the system can automatically play the real-time image of the corresponding side in full screen according to the turning direction, and provide the image of the blind area of the field of vision for the driver to prevent accidents. However, when the vehicle backs up, the system can judge whether to automatically display the rear image in full screen according to the setting of the user, and some users feel that it is more convenient to back up by using the 4-way 360-degree image. In addition, icons of the reversing auxiliary LED lamps are arranged on the rear image split screen, and the rear reversing auxiliary LED lamps can be turned on or off by clicking with hands.

The navigation function page can input addresses by hand or voice, and operation of a user is facilitated. In addition, the screen can also display real-time speed, oil consumption and other related information during navigation.

the content displayed on the special vehicle auxiliary function page can be different according to different types of the hung semitrailers, and is mainly used for assisting the operation safety of a user during operation. After entering the page, the controller can compare the model of the sensor connected to the hung semitrailer with the model in the database, and if the database has no corresponding model, a prompt such as 'the type of the semitrailer which can be identified cannot be found' can be displayed on the screen, so that a user is reminded that the sensor of the semitrailer is possibly damaged or the type of a new special semitrailer which is hung needs to be identified by upgrading the database. If the identification is successful, the host displays the content on the display screen according to the corresponding setting. For example:

(1) The backward tipping self-unloading semi-trailer is generally provided with a 0-15-degree high-precision angle sensor which is generally arranged on a cross beam at the bottom of a carriage and can identify the horizontal inclination angle of the carriage. Because the car can be lifted and inclined to turn on one side if the ground is uneven or soft when unloading. Therefore, after the host machine recognizes that the self-discharging semitrailer is turned backwards, the auxiliary function page of the special vehicle can display the real-time image of the rear camera and monitor the horizontal inclination angle of the carriage during operation. The real-time image of the rear camera can enable a driver to see whether the automatic lock hook of the rear door falls off or not and whether the rear door is opened or not after the oil cylinder is lifted, so that accidents caused by the fact that the automatic lock hook is not opened are avoided. In addition, when the system monitors that the horizontal inclination angle of the carriage is larger than the set threshold value, the system can display 'the vehicle body inclines and please stop the lifting operation' on the screen and also can display the same voice prompt.

(2) The side-tipping self-unloading semi-trailer is generally provided with an angle sensor of +90 to-90 degrees, and the angle sensor is generally arranged on a cross beam at the bottom of a carriage and can identify the horizontal inclination angle of the carriage. After the host machine recognizes that the side-tipping self-unloading semitrailer is a side-tipping semitrailer, the side-tipping semitrailer can be designed to tip on one side or two sides, so that the auxiliary function page of the special vehicle can display real-time unloading images of the camera on the corresponding side according to the tipping direction during operation, and can display the tipping angle of a carriage during operation on a screen in real time. Due to the fact that the viscosity of materials of the device is different, the unloading speed is different greatly, and side turning accidents can happen when the unloading speed is slow or the lifting speed is too fast due to the fact that a side turning door is blocked. The system can better assist a driver to control the lifting speed according to the material unloading speed, so that accidents are prevented.

(3) the refrigerated transport semitrailer is generally provided with a temperature sensor, the system can monitor and record the temperature of a carriage in the whole process, and an alarm temperature value can be set on an auxiliary function page of a special vehicle. When the temperature in the vehicle cabin is higher than the set value, the voice prompt is given, such as 'the temperature in the vehicle cabin is higher than the set value, please note' but the display content picture is not switched to the special vehicle auxiliary function page.

In addition, other types of semitrailers may be equipped with pressure sensors or other types of sensors whose specific vehicle auxiliary function pages will be displayed in a customized manner according to their specific needs.

It should be noted that the host and the data acquisition system may be connected by wireless communication; the arrangement order of the 4-way image display and the order of the function pages are not necessarily in the order shown in fig. 5; the key sequence and functions of the display screen and the host computer may be changed to some extent along with the product upgrade; the communication module is not necessarily in a 4G mode and can change along with the technical upgrade; the navigation system can select GPS or Beidou series, and the like, which belong to the protection scope of the invention.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
