WiFi智能小车的不同控制方式设计与实现

Design and Implementation of Different Control Modes for WiFi Smart Car

提供了一种使用同一安卓APP近程和远程控制wifi智能小车的方法。安卓APP可以在智能小车的WiFi状态下近程控制智能小车,分别借助于安卓系统的开源java-websocket的jre包和Open WRT系统的开源libwebsocket插件,在安卓APP和智能小车的主控板Wrtnode上实现websocket协议功能,通过websocket server中转实现远程控制效果。安卓APP通过json格式下发控制指令,能够控制智能小车的前后左右停及摄像头的旋转,智能小车根据控制指令分别采用文本格式和二进制格式上报传感数据和监控画面,为WiFi智能设备提供多种控制方式的解决方案。

This paper presents different control solutions for smart car with Android APP. The Android APP that has access to WiFi of smart car can control smart car under a short range. With the open-source jar package of java- websocket and the libwebsocket plug-in of OpenWRT, the Android APP and Wrtnode of smart car can separately implement the websocket function. With the transfer of Websocket Server, the Android APP realizes remote control of smart car. The Android APP sends control instruction in json format, which can control the ear action and the camera rotation. The smart car reports data of sensor with text format and monitoring screen with binary format separately and therefor offers solutions with lots of controlling methods for WiFi smart devices.
