受限区域空气环境探测吊舱系统的设计

Design of air environment of restricted area detected pod system

针对无法高效便捷地检测高空受限区域空气环境的问题,设计了受限区域空气环境探测吊舱系统,该系统以MT7620N芯片作为主控单元,搭载OpenWrt操作系统,设计北斗GPS定位模块、空气样本采集装置、多种空气参数探测传感器和视频采集装置.智能监测服务终端可实时查看受限区域的温度、湿度、烟雾浓度、PM2.5、PM10、现场视频及地理位置等信息.经测试,该系统可准确测量空气质量参数,通信距离能够达到150 m,通过搭载在旋翼机上的探测吊舱灵活探测高空某一区域内空气污染状况,从而为污染评估,决策预警和环境执法提供有力的数据支持与保障.

Aiming at the problem that the air environment in restricted high-altitude areas cannot be detected efficiently and conveniently, a restricted area air environment detection within pod system was designed. The MT7620 N chip was selected as the main control unit, the OpenWrt operating system was equipped with the system and Beidou GPS positioning module,air sample collection device, multiple air parameter detection sensors and video collection device were also designed. The temperature, humidity, smoke concentration, PM2.5,PM10,on-site video and geographic location information in the restricted area can be viewed by the intelligent monitoring service terminal in real time. The air quality parameters can be measured accurately and the communication distance can reach 150 meters after system testing. The system can detect air pollution in a certain area at high altitude flexibly by being mounted on a rotorcraft, which can provide strong data support and guarantee for pollution assessment, decision-making and early warning, and environmental law enforcement.
