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.
本发明所得到的基于Android的LCD显示终端联动控制方法,包括LCD显示终端、车载报站器、车载扬声器和后台服务器,所述的LCD显示终端基于Android系统,包括有Rockchip RK3288芯片,且LCD显示终端为竖置设置,其显示的内容分为上下两块,车载报站器与LCD显示终端同时通过RS485接口和音频接口连接,其以基于Android的LCD显示终端为主要控制中心,将车载报站器的RS485通信接口数据和音频接口数据同时发送到LCD显示终端,利用Android系统自身的音量控制特点,通过检测报站器的RS485命令,可以实现对车身扬声器的两路音源控制,解决混音的问题。同时还针对LCD显示终端设计了一整套的信息显示和控制的方法,达到了只需维护LCD显示终端即可实现整车多媒体控制的目的。
