Abstract

The invention discloses a system for solving vehicle-mounted multimedia feed. The system comprises a multimedia host end, an automobile end and other electronic equipment ends. The multimedia host endcomprises an MCU processor, a multimedia control panel, a voltage detection module, a power amplifier and a loudspeaker. Other electronic equipment ends comprise an electronic equipment host and an equipment control panel. The automobile end comprises an engine, a charging module, an automobile battery and a power management module. The automobile battery supplies power to the MCU processor, themultimedia control panel, the voltage detection module, the power amplifier, the loudspeaker, the electronic equipment host and the equipment control panel, and the MCU processor is electrically connected with the electronic equipment host. The voltage detection module is used for detecting the voltage of the automobile battery in real time, and when the voltage of the automobile battery is continuously lower than a prompt voltage threshold value, the MCU processor sends a voice prompt signal to the power amplifier and the loudspeaker. According to the scheme, due to the humanized design, theintelligence of the vehicle-mounted multimedia is improved, meanwhile, the automobile battery is protected against feed, and the service life of the automobile battery is prolonged.

Description

technical field [0001] The invention relates to the technical field of vehicle multimedia, in particular to a system and an implementation method for solving vehicle multimedia power feeding. Background technique [0002] As a part of the body electronic equipment, the car multimedia is a high-power device, which can reach 20W when working, such as figure 1 As shown, the customer requires a wide operating voltage range of the multimedia host (such as V1~V3), and requires that it can continue to work at a lower voltage (such as V1), and the minimum starting voltage of the car (such as V2) is higher than the minimum of the multimedia host. Working voltage (such as V1), for users who frequently stop and turn off the engine, listen to music and watch videos as entertainment and release pressure, if they use high-power equipment for a long time in the turned off state, there are the following problems: [0003] (1) It will speed up the discharge speed of the car battery, and the...
