Embodiment Construction

[0037] A system for rapid video transmission in vehicle yards, see figure 1 ,include

[0038] Bus: used to carry passengers and carry on-board machines;

[0039] Audio and video acquisition module: installed in the bus, collects the audio and video data in the bus and transmits it to the on-board machine, and can use cameras, loudspeakers and other equipment;

[0040] Field area: used to park buses;

[0041] System platform: set up in the field area, used to establish a communication connection with the vehicle-mounted machine, and store the data information transmitted by the vehicle-mounted machine;

[0042] Field area WIFI module: set in the field area, after the bus arrives at the field area, the vehicle-mounted machine establishes a communication connection with the system platform in the field area through the vehicle-mounted machine WIFI module and the field area WIFI module;

[0043] Vehicle-mounted machine: installed in the bus, used to store data information, data...

Abstract

A system for fast video transmission in vehicle yards, including buses, audio and video acquisition modules, yards, system platforms, yard WIFI modules, vehicle-mounted machines, SSD solid state drives, and vehicle-mounted machine WIFI modules; a system based on vehicle yard video recording The data transmission method of the fast transmission system includes the establishment of the link, the transmission of audio and video data, the switching of the WIFI of the vehicle, and the switching of the AP mode of the WIFI of the vehicle. The on-board computer of the bus does not need to be equipped with a large-capacity mechanical hard disk, and the SSD hard disk with a small storage capacity is used instead of a large-capacity mechanical hard disk, which solves the problem that audio and video data are prone to errors in a vibration environment.

Description

technical field [0001] The invention belongs to the technical field of wireless transmission of vehicle equipment, and mainly relates to a system and method for fast video transmission in a vehicle field. Background technique [0002] Most of the existing buses are equipped with on-board computers, which are mainly used to store audio and video data. The existing on-board computers require large-capacity hard disks to store relatively long-term audio and video data. However, as 720P, 1080P, 4K For the application of high-definition video data, a large-capacity hard disk cannot meet the demand. The vehicle-mounted machine equipped with a large-capacity hard disk has a bulky appearance, and the hard disk box needs to be considered in the structural design. Large-capacity mechanical hard disks have poor anti-vibration performance, and shock-absorbing measures need to be considered, and the interface between SATA and power cables must also undergo special treatment to prevent l...
