The Design Of Software Of The Gamma’s Spectrometer According To The LabVIEW

γ ray spectrometry is a very important nuclear geophysical method, it usuallysolves many problems such as geosciences and environment. It can directly measure thecontent of U, Th, K in the rocks’ surface, soil, ore.And obtaining the information ofrelevant nuclide. Meanwhile, it has a very important role for uranium exploration, theanalysis of rock, customs and quarantine, surveying and environmental gas radiationdetection.To adapt to the need of environmental testing for γ spectrometer, it is the purposeof this article to use the technology of virtual instrument in designing and developingthis γ spectrometer, the work we have done mainly have:①Analysis the various components of the virtual γ spectrometer, build ahardware platform γ spectrometer and provide a test platform.②Use LabVIEW which is the virtual instrument development platform, establishthe software of virtual γ spectrometer, complete the communication of spectral data, themanagement of file of spectral data, the smoothing of spectral data, peak searching,seeking resolution, scale calibration, nuclide analysis.③Use the software of virtual γ spectrometer which is completed and the hardwareplatform which is finished to test instrument and analysis performance.Take the advantage of existing abundant computer resource of software andhardware, make use of virtual instrument, the γ spectrometer which is designed anddeveloped has many merits such as amicable, beautiful software’s interface, easyexpansion, maintenance. The Spectrometer which is designed preliminary can meet theneeds of test equipment. Use the technology of virtual instrument in designing anddeveloping this γ spectrometer. This design is theoretically correct and feasible inpractice.
