Abstract

The invention discloses an Android-based LCD display terminal linkage control method. The Android-based LCD display terminal linkage control method comprises an LCD display terminal, a vehicle-mountedstation broadcaster, a vehicle-mounted loudspeaker and a background server, wherein the LCD display terminal is based on an Android system, comprises a Rockchip RK3288 chip, and is vertically arranged; the displayed content of the LCD display terminal is divided into an upper block and a lower block; the vehicle-mounted station broadcaster and the LCD display terminal are connected by means of anRS485 interface and an audio interface at the same time; the LCD display terminal based on Android is used as a main control center; RS485 communication interface data and audio interface data of thevehicle-mounted station broadcaster are sent to the LCD display terminal at the same time; volume control characteristics of the Android system are utilized, and two paths of sound sources of the vehicle-mounted loudspeaker can be controlled by detecting RS485 commands of the station broadcaster; and the problem of sound mixing is solved. Meanwhile, a whole set of information display and controlmethod is designed for the LCD display terminal, and the purpose that multimedia control over the whole vehicle can be realized only by maintaining the LCD display terminal is achieved.
