The Design And Development Of Multi-channel γ Spectrometer Measurement And Analysis Software Based On Android

Gamma spectrometer is mainly used to measure the content of radioactivenuclide,the analysis software of which is used to process data collected,so that it cancalculate the content of material measured and what kind ofradionuclides.Spectrometer analysis software at present is mainly based on PDA andWindows platform, in order to realize the diversity of application platform, designedand developed spectrometer analysis software based on Android platform.Android is a kind of more popular mobile device operating system with wideusers,miniature and light weight,reasonable price,high cost-effective,fast updatingspeed,high degree of integration and achieving a variety of functions.Themulti-channelγspectrometer measurement and analysis software based on androidas a platform for android4.0and the development tools for the SDK is developed andcomplete the whole program for the development of transplant debugging and testingwork.The article is mainly about the design and development of multi-channel γspectrometer measurement and analysis software for android.The software is suitablefor the android. In the process of software development, the article implements thefollowing design in order to be developed with the excellent man-machine interactiveoperation,real-time data acquisition,spectrum line shows,data processing, contentanalysis and file operations and so on.The software design wireless communicationfunction that can achieve data transmission by bluetooth to increase the accuracy andreliability of data transmission.It adopts multi-threading to achieve datainterchanger,design of the counter,sustained accuracy,etc.The software can achievemobile phone UI layout to show spectrum data by using logarithmic and linear. Thesoftware can achieve intelligent spectrum data processing, show channels,count and energy and designed five point-three times of the first derivative and secondderivative methods to search the data smoothed peak.Setting the nuclide library, thesoftware can automatically find the corresponding nuclide.The software design GPSpositioning function to record the location of the material being tested and show thelatitude and longitude.Because of the characteristic of the smaller Android mobilephone screen, the software design for a large number of input box and the pop-up boxthat are convenient for data input and display in order to operate simple and quickly.
