Research And Implementation Of A Radioactive Monitoring System And Key Technologies For Automated Inspection

With the deepening of the understanding of nuclear physics,a large number of radioactive materials are used in our lives.The application of radioactive elements has brought many dangers while improving people’s living conditions.The radiation emitted by radioactive materials can cause harm to the human body without knowing it.In order to control radioactive materials better,radioactive monitoring is particularly important.After research on radioactive monitoring products at home and abroad,this thesis designs and implements a radioactive monitoring system which based on Android operating system for mobile radioactive iodine monitor.Then,in view of the shortcomings of the monitors that need to use human power frequently,this thesis designs an automatic inspection framework,researches key technologies in automatic inspection and implements the prototype.This automatic inspection framework combines embedded development technollogy and object detection technology.This thesis first analyzes the requirements of the radioactive monitoring system.Its functional requirements include sampling monitoring,data storage,data display,parameter setting and user management.This thesis also analyzes the non-functional requirements of the system.According to the requirements,this thesis designed the system architecture,user interface,communication interface and database,at the same time this thesis partitions system module.Next,the system’s sampling monitoring module,data query module,user management module,parameter setting module and data communication module are designed and implemented,and the feasibility of the system is verified in the simulated environment.Because the monitor can’t move conveniently,this thesis designs an automatic inspection framework,and researches four key technologies,such as navigation method,obstacle ranging,obstacle detection and obstacle avoidance strategy.Then,the automatic inspection framework was implemented.Finally,the work of this topic is summarized,pointing out the shortcomings and research directions of future.
