Development Of Nuclear Energy Spectrum Measurement System Based On Android Platform

With the continuous improvement of China's scientific research capabilities in nuclear energy,scientists have also increased the use of nuclear energy,and the use of nuclear energy has gradually penetrated into the military,industry,agriculture,scientific research,and medical and health fields.In the industry,nuclear radiation is often used for processing,such as disinfection of medical devices and pharmaceutical products,preservation of foods,etc.;nuclear radiation mutation breeding and pest control are often used in agriculture;nuclear radiation is often used in medicine for disease treatment.For example,the radiology department is always in the hospital.However,due to the nuclear radiation safety problems brought about by the development of nuclear energy,the personal health of citizens is threatened.From the perspective of Scope Environmental Nuclear Data Monitoring,it is of great practical significance to establish a safe and effective wireless sensor monitoring network to accurately grasp the surrounding nuclear energy spectrum data,nuclear accident emergency protection,reduce the incidence of nuclear accidents and ensure nuclear safety.Domestic nuclear energy spectrum measurement is limited to point-to-point measurement.That is,the nuclear energy spectrum analyzer can only analyze the nuclear energy spectrum data transmitted by the energy spectrometer associated with it,and cannot achieve multi-point nuclear data monitoring.In order to be able to monitor a wide range of nuclear energy spectrum data system and provide workers with a safe,comfortable and real-time view of nuclear energy spectrum data,a remote control,realtime measurement of data and accurate display of on-site nuclear radiation data is required.Therefore,this paper proposes a scheme based on the Android platform for nuclear energy spectrum measurement system.In this paper,based on the intelligent development trend of nuclear energy spectrometer and the use of Android platform as the mobile terminal system with the highest market share,the wireless network nuclear energy spectrum measurement system based on Android system is designed.The system selects the ESP8266 wireless module as the network node to build the network hardware platform,sets it to the station mode,uploads the energy spectrum data to the cloud server through the connection router,and the user can select the required network point by connecting to the cloud server on the Android terminal.The data is converted into a data format that the terminal can recognize.The software is based on Android Studio development platform,based on JAVA language,the whole interface is simple and beautiful,and multi-thread technology is used to realize data transmission,reading and writing,and line drawing operation.The software can realize the qualitative analysis of the gamma energy spectrum analyzer,including the smoothness of the line,the peak finding,the calculated peak area and the energy scale.The main functions implemented in the paper are:1.In the Android terminal program,the spectrum display interface sets the scroll view,so that the Android platform of various screen sizes can affect the display incompleteness caused by the size of the screen.2.In the wireless network node program,add the SPI communication protocol to the official SDK routine of ESP8266,so that the high-speed and stable transmission of data can be realized between the MCU and the ESP8266 module.3.In the communication between the wireless network node and the cloud server,after registering and configuring related information on the cloud server official website,the ESP8266 connects to the remote cloud through the router and uploads the nuclear energy spectrum data.4.In the communication between the Android terminal and the cloud server,the APP connects to the cloud server through the Internet to download data and retrieves the corresponding nuclear energy spectrum data through the selection node,thereby realizing the remote transmission and control of the nuclear energy spectrum data.5.In order to enable the Android terminal software to qualitatively analyze the nuclear energy spectrum,the design adds functions such as smoothing the spectrum,searching for peaks,and querying the nuclide library.
