Research And Implementation Of Nuclear Radiation Detection System Based On UAV

Nuclear technology has developed rapidly in recent years,and it is more and more widely applied into life.People will be exposed to a certain dose of nuclear radiation in their work or life,and with the outbreak of more and more global nuclear accidents in recent years.The issue of nuclear radiation has attracted more and more attention.At present,the acquisition of nuclear radiation data is still in the stage of relying on one technical personnel to go to the scene or another one is install radiation detection system in place where detection system is needed,which not only needs a lot of equipment,but also needs equipment maintenance staff.The two ways all not only waste financial resources but also endangering the safety of testing personnel.So,developing long-distance transmission system can move applying for nuclear radiation is even more important.The development of UAV technology provides a new way to solve this problem,and its good maneuverability can improve work efficiency.Firstly,this paper introduces the current situation of the nuclear radiation data acquisition system and transmission system,and analyzes the shortcomings of the existing nuclear radiation acquisition system,which is a waste of financial resources and poor security.Therefore,a remote wireless data acquisition and transmission system is designed for real-time transmission and storage of nuclear radiation data.n the hardware design,the volume power consumption of each module is fully considered.G-M is chosen as the detector,low power processor STM32 is chosen as the main controller,and its field bus interface is used to expand the position,temperature and other multi-channel sensor information to analyze the local nuclear radiation data.In terms of data transmission,GPRS wireless transceiver module SIM800 C is selected from the point of reliability.Using GPRS network,data application protocol is formulated to realize remote data transmission.In addition,the radiation dose conversion algorithm of nuclear pulse counting and the software design idea of data transmission are given.In the MDK environment,the C language is used to write the communication and main control program of each module.The upper computer client and the airborne nuclear radiation detection terminal of this system adopt TCP/IP protocol to receive data,and the data storage uses DCT toolkit to write the data and query the data of the connection between LABVIEW and Microsoft Access.The staff promptly inquired about nuclear radiation information and reviewed historical data.Tests show that the system has good real-time performance.small size and other characteristics.This project not only has a certain significance to broaden the application field of UAV,but also would give some useful and meaningful references to other aspects of data detection.
