Description

Vehicle-mounted sound equipment host system

Technical Field

The utility model relates to the technical field of information processing and propagation, in particular to a vehicle-mounted sound host system.

Background

Car stereos play a significant part of the work in car entertainment systems. The existing vehicle-mounted sound host comprises a sound host body and a machine core. Along with the development of electronic mobile media, different requirements are met, and the movement needs to be flexibly configured. The traditional mode of the host machine with a built-in machine core cannot meet the requirement. The movement is required to be independent of the main machine, so that the movement becomes an external device of the main machine. Use CAN to communicate between core and the stereo set host computer, because communication between host computer and the core has the characteristics that communication distance is long, exchange data is big, if adopt low-speed CAN communication to occupy a large amount of frame sections of CAN according to traditional communication mode, CAN not satisfy information such as the song name of song in time and show, if use high-speed CAN, then whole CAN communication network all needs the promotion speed. Most of vehicle-mounted computer schemes of mainstream android systems only support WIFI to be connected to the Internet, and few of vehicle-mounted computer schemes are connected through an external USB (universal serial bus) network card. The methods have the disadvantages of slow internet speed, high cost, complex manual intervention for many operations, trouble and long period for upgrading a console because a hardware platform is embedded in an automobile, and incapability of realizing cloud function upgrading, remote center management and the like of a vehicle-mounted information system. With the development of electronic information technology, the explosive development of mobile internet and the proposal of internet of things, various requirements of people are excited, and the existing automobile electronics can not be met far away.
