Description

Technical Field

[0001] The utility model relates to the technical field of bus audio - video control, and particularly relates to an intelligent central control display system for buses. Background Art

[0002] In the current tourist bus and long - distance freight transportation industries, with the continuous improvement of the requirements of passengers and drivers for the riding experience, the configuration of the entertainment system, especially the function of playing videos, has become one of the key factors to improve the riding comfort and satisfaction. Traditionally, the entertainment systems inside vehicles often use a single playback source, which is difficult to meet the different needs of drivers and passengers for video content. Drivers need to focus on road conditions, while passengers tend to watch diverse entertainment programs to relieve travel fatigue.

[0003] To solve this contradiction, central control entertainment systems that can distinguish between the driver's and passengers' playback areas have gradually emerged in the market. However, in actual applications, such systems often face challenges in limited installation space. The interior space of tourist buses and long - distance freight vehicles is limited, and a large amount of space needs to be reserved for passenger seats, luggage storage, and necessary driving operation areas, which greatly restricts the installation and layout of the central control entertainment system. How to achieve independent playback areas for drivers and passengers within limited space while ensuring the functional integrity and operational convenience of the entertainment system has become an urgent problem to be solved. Summary of the Utility Model

[0004] To overcome the deficiencies of the prior art, this application provides an intelligent central control display system for buses, aiming to achieve independent playback areas for drivers and passengers within limited installation space and integrate them for control on the same display interface without interference during operation.
