1、学号年级本科毕业论文基于WiFi的多功能搜救机器人软件设计 专业自动化姓名指导教师评阅人年月71BACHELOR'SDEGREETHESISOFHOHAIUNIVERSITYMultifunctionofsearchandrescuerobotbasedonWiFisoftwaredesignCollege:Subject:Name:Directedby:71摘要当灾害发生后,受灾地区环境十分复杂,潜在的危险极大,例如地震后的危楼,火灾现场等等,一些狭小区域的救援工作更是难上加难。复杂环境下,温度,湿度,
2、空气中氧气和有毒气体的含量都是被困人员能否生存下来的决定性因素,也是救援人员制定救援计划的关键信息。另外在搜救过程中人手十分有限,危险或狭窄地区的作业更需要机器人来完成,这样才能有效地保证救援人员的安全和救援任务的顺利进行。本文描述的基于WiFi的多功能搜救机器人搭载具有开源OpenWrt的Linux操作系统的无线路由器,通过Mjpg-Streamer图像压缩技术和Ser2net的网络串口协议,辅以STC89S52单片机可以将网络摄像头拍摄的实时视频和传感器采集的环境变量参数传回控制端。控制端由Visua
3、lStudioC#编写的PC上位机和JavaScript编写的移动控制端组成,可以显示图像并记录数据,通过方便的图形化界面,救援人员可以轻松的连接路由器的WiFi局域网,获取各种数据,并使用上位机发送命令控制机器人的行动,这可以极大降低救援工作的危险性,提高救援的成功率,为被困人员带来生的希望。关键词:搜救机器人;WiFi技术;OpenWrt系统;视频传输;数据传输;71ABSTRACTAfterthedisaster,theaffectedareaismorecomplex,thelatentdange
