针对现有的搜索救援系统存在的搜救效率低下和容易发生二次灾害等不足,研究了一种以无线通信技术为核心的无人机搜索救援系统,主要讨论了机载探测器的设计。系统以MSP430微处理器为控制单元,机载探测器通过无线收发模块RFC33 A与救援信标机通信,激活信标机并接收信标机获取的遇险人员地理位置信息,通过数传电台XTend将信息实时地传回地面站以及接收地面站的控制指令。实验测试表明,机载探测器对信标机的有效探测距离达到2 km,与地面站的通信距离大约为10 km,工作时间超过3 h,实现了搜索的目的。

To overcome the shortcomings of inefficiency and secondary disasters in existing search and res-cue systems,an unmanned aerial vehicle( UAV) search and rescue system employing wireless communica-tion technology is studied. The airborne detector's design is mainly discussed. The MSP430 microproces-sor is selected as the control unit. Airborne detector communicates with rescue beacon machine through RFC33A wireless receiving-sending module,then it activates rescue beacon machine and receives geo-graphical location information for persons in distress from beacons. The data transceiver XTend is used to send real-time information to the ground station and receive control commands from ground station. Exper-iment results show that the effective detection range of airborne detector to beacon machine reaches 2 km, the communication range of ground station is about 10 km and its working time is more than 3 hours. The system achieves the goal of search.
