Description

Technical Field

[0001] The present invention belongs to the technical field of special vehicles, and in particular relates to a mobile network live broadcast vehicle based on multi-functional integration. Background Art

[0002] With the rapid development of Internet technology, live broadcasting has become an important way of information dissemination and entertainment. For example, merchants promote and display products through live broadcasting, and interact with the audience in real time, thereby attracting buyers and facilitating orders. At the same time, functional live broadcast rooms and live broadcasting with goods have mature applications in all walks of life. In order to adapt to the rapid development of the live broadcast industry, mobile live broadcast vehicles have also emerged. This kind of live broadcast vehicle not only has the various functions required for film and television production, but also has the characteristics of high efficiency, stability and flexibility, which has brought great convenience to the production of live broadcast images. The evolution of live broadcast vehicles began with the traditional cable TV signal transmission mode. Its core relies on the fixed link architecture of ground base stations and satellite relays, and has the defects of rigid deployment and limited coverage. For example, in the prior art, the invention patent with Chinese patent application publication number CN114245037A discloses a network news live broadcast vehicle, including a live broadcast vehicle body and a lighting adjustment system, the upper surface of the live broadcast vehicle body is fixedly connected with a top plate, and the upper surface of the top plate is fixedly installed with a rotating mechanism. The patent starts the adjusting motor to drive the adjusting gear to rotate through the arrangement of structures such as a rotating motor, a rotating gear, a gear ring, an adjusting motor, an adjusting gear, a first gear plate, and a second gear plate. The adjusting gear drives the first gear plate and the second gear plate to move and move the two solar panels thereon away from each other, and moves the telescopic frame outward, thereby increasing the shading range of the live broadcast vehicle while facilitating the storage of the solar panels when not in use, thereby reducing space occupancy. However, the functionality of the patented technology is relatively small and cannot adapt to work requirements such as mobile live broadcast. In addition, the existing traditional live broadcast vehicles only focus on audio and video acquisition and transmission, with single functions (such as TV live broadcast vehicles only support one-way broadcasting), and cannot adapt to the multi-task concurrent needs of the media convergence era; there is also a problem of strong network dependence. Existing equipment is difficult to ensure the continuity of live broadcasts in areas without stable networks (such as rural areas and the wild), and lacks a multi-network redundant transmission mechanism; and the existing live broadcast vehicles have poor scene adaptability, poor spatial interactivity, and cannot provide a horizontal work surface; the fixed broadcast equipment usually installed on the vehicle body cannot be quickly switched to the market, stage and other forms, and lacks training support modules. Although some existing manufacturers have proposed the concept of Internet news live broadcast vehicles, they have not solved core issues such as multi-functional integration, extreme environment protection and user interaction training.

[0003] In view of the above situation, the core problem of the existing technology lies in that there is still much room for improvement in the functional integration, space efficiency and intelligence of existing network live broadcast vehicles. Therefore, there is an urgent need for an innovative live broadcast vehicle system that can achieve function integration, space conversion and full-link intelligent control. For this reason, the applicant has made a beneficial design, and the technical solution to be introduced below was generated under this background. Summary of the Invention
