Research Of HK-2 Sylvite Logging Spectrometer

China's growth trend of potash consumption in the coming decades will continue, predicts 2010 will reach 100 million tons of the world's total, approximately 1/4, market value will exceed $14 billion. If most of such large amounts of potash supply is still from the international market ,China will bear huge trade risk. Once big price fluctuations or extreme events appears, it will brings China agriculture development very serious influence. Meanwhile,If hand over such huge market to foreign countries, potash on China's economic development is itself a big loss. The price of sylvite product is seriously restricted by the international market, potassium by serious shortage has been listed as countries focus on strengthening minerals.At present the potash resources in China is far below the production requirements of the development of modern agriculture, Not only can promote the potash resources related industry, enhance the development of national economy, but also helps to relieve pressure, improve sylvite imported agricultural value. At the same time, this project to solve the local employment, promoting trade and related to the prosperity and stability of border area also has important significance.This gamma spectrometer for measuring technology of related principle and system implementation scheme are discussed, with DSP controller design for the gamma spectrometer, the study of data acquisition system and its application in the potassium mineral logging, as sylvite deposits offer guidance significance to the development of energy. This essay introduces system??n-machine interface, interrupt collection procedures, serial communication program, PC software and data processing program to Auto CAD file format conversion and other related content.This topic using DSP (TMS320LF2407) brings ADC multichannel measurement, andγspectrometer through PC machine control commands sent down, realize the control parameters, instrument, data collection and transmission of the data in the PC display and mapping.
