基于无人机技术的口岸核与辐射突发事件应急侦测系统研制

Development of Detection System Based on Drone Technology Used for Nuclear and Radiation Emergency Response in Ports

为了满足海关工作人员在应对口岸核与辐射突发事件时,对于危险区域或不可到达区域的辐射水平的监测需求,本研究基于多旋翼无人机平台、高气压电离室辐射探测器、差分定位、远程无线传输、高德地图SDK、Qt图形化等技术研制了口岸核与辐射突发事件应急侦测系统,并生产出样机。该系统初步实现了远程、非接触、高灵敏度辐射探测,降低了海关工作人员辐射暴露风险。同时,该系统结合地理信息系统实现区域辐射水平分布三维描绘,为准确、充分了解突发事件现场辐射危害状况,采取正确应对策略提供了新的手段。

In order to meet the needs of customs staff to monitor the radiation level in dangerous or unreachable areas when dealing with nuclear and radiation emergencies in ports,a port nuclear and radiation emergency detection system with a sample machine was developed based on techniques including multi-rotor drone platform,high-pressure ionization chamber radiation detector,differential positioning,remote wireless transmission,AMap SDK,and Qt graphics.The system preliminary realized longdistance,non-contact and high-sensitivity radiation detection,reducing the radiation exposure risk of customs staff.At the same time,it achieved the three-dimensional description of regional radiation level distribution combined with geographic information system,which provides a new means to accurately and fully understand the radiation hazard situation at the scene of emergencies and adopt correct response measures.
