Research And Prototype Implementation Of Radioactive Source Movement Monitoring System

As more and more radioactive sources are put into use in industrial,agriculture,medical,archaeological and other fields,the loss or theft of radioactive source is not uncommon.After the radioactive source is lost or stolen,how to do a good job of finding a source has gradually been put on the agenda.In most cases,after a radioactive source is lost or stolen,practitioners carry detectors and search for radioactive sources based on experiences,usually lack a complete set of radioactive monitoring system and source-seeking algorithm.In order to solve the above problems,this thesis summarizes the existing radioactive monitoring systems and source-seeking algorithms,and investigates the related technologies.After that,monitoring equipment was provided by enterprises as a hardware foundation,we designed and implemented the radioactive source movement monitoring system and studied the source-seeking algorithm.In the process of designing and implementing the radioactive source movement monitoring system,based on the requirement analysis,the functional requirements are defined.Then the system is divided into Bluetooth pairing,intelligent monitoring,I/O testing,parameter setting,data management and data upload six modules.In addition,describes the specific functions of each module,and designs the communication interface.After that,elaborates design and the realization of each module detailed.In the process of study on source-seeking algorithm,this paper analyzes the actual source-seeking scene,researches and realizes the source-seeking algorithm based on interpolation.Aiming at the grid limitation of this algorithm,a source search algorithm based on GIS and BP neural network is designed.Then,from the radiation protection point of view,a hybrid source-seeking model is proposed,which uses source-seeking algorithm based on GIS and BP neural network or source-seeking algorithm based on GIS and DBSCAN clustering algorithm fitting center respectively,ensuring the safety of employees.Finally,this paper elaborates the design and implementation of system testing tools and the testing results of the main functional modules,summarizes the work of the dissertation,and looks forward to the direction of improvement.
