Abstract: An intelligent detection system based on the LORA and quadrotor is designed to grasp atmospheric environment information in real time, improve work efficiency, and reduce labor cost. In the system, with the STM32 microprocessor as the central controller and the quadrotor aircraft as the sensor platform, the LORA spread spectrum technology is adopted to transmit the collected data to the monitoring terminal node, so as to realize real?time display of the atmospheric environment. The experimental results show that the system has the characteristics of good real?time performance, wide detection range, and low overall power consumption, which has a wide application prospect.

随着工业化和城镇化进程的加快,有毒、有害等突发性大气污染和城镇雾霾频发,严重威胁了人类的生存和发展,已被评为地球上“最危险的环境致癌物质之一”[1?2]。因此,如何方便、及时地获取精准、可靠的大气环境基础数据资料,实现对大气环境的有效监控和保护成为亟待解决的问题。现有的大气环境检测方法主要分为两种:一是采用便携式空气监测仪人工采样、分析的方式;二是采用由远程监测中心和若干个监测子站组成的大气环境自动监测系统[3?4]。前者存在劳动强度大、时间周期长、针对性差、数据采集慢等问题,无法反映大气环境动态变化,且不易及早发现污染源并报警。后者虽能较好解决上述不足,但需要预先铺设电缆并建立多个监测子站,存在系统成本高、监测大气范围有限、易对监测区域造成破环等缺点。
本文结合了LORA扩频技术[5?6]和四旋翼飞行器[7?8]的双重优势,设计一种大气环境智能测试系统。……
