摘要
针对电站中电力系统环境复杂的问题,设计了一种基于改进的OpenWrt系统和Android系统的电站智能无线巡检机器人。该系统以无线嵌入式处理器AR9331和基于Cortex-M3的ARM处理器STM32为双处理器核心,并在无线处理器上运行改进的OpenWrt操作系统,实现无线路由功能,同时引进一种新型的MJPEG压缩算法。实现了Android智能手机对巡检机器人的无线控制、视频实时采集与显示。经设计研发和现场测试,系统可运行在电站狭小、阴暗等复杂环境中,完成无线巡检任务,具有良好的稳定性和灵活性。
For the complex problem of the power system environment in power station,a smart wireless inspecting mobile robot is de-signed based on improved OpenWrt OS and Android OS. Wireless embedded processor AR9331 and STM32 micro-controller based on Cortex-M3 are taken as the dual processor in the system,and the wireless embedded processor runs the improved OpenWrt OS to imple-ment wireless routing function. At the same time it also introduce a new type of MJPEG compression algorithm. The system implements the wireless control,real-time video acquisition and display of inspecting mobile robot used by Android smart phone. With the design and the field test,the robot can complete the inspecting tasks in complex environment such as narrow and dark in power station,which has great stability and flexibility.
