The Research Of Nuclear Prospecting Data Collection And Processing System Based On 3GS

The paper sketches the present situation of the portable nuclear prospecting instrument. Most of them can only finish the spectrum collection and simple data processing. GPS has embedded in a few of nuclear prospecting instrument. But they all adopt external GPS module and only achieve the GPS positioning, they can not finish the automatic and digital collecting of the environmental information such as humidity, temperature, geology, topography and so on, which are needed by prospecting work. In nuclear prospecting data processing, the drawing of map(such as plan contour map and color image) is finished by using some plotting software such as SURFER, which only plot graph and can not contact with actual geographical map. The application of GIS in nuclear prospecting field is the initial stage.On today of the 21th Century, technical integrated innovation is encouraged. As the rapidly developing of GPS, GIS, GPRS, national nuclear prospecting instrument should have a new mentality. So author put forward an idea of leading GPS, GIS, smart mobile phone and wireless communication technology into the nuclear prospecting instrument and data processing system. The smart mobile phone is as the working platforms, the GPS position data, the radiation spectrum, picture or video information and word picture are collected together and transported to indoor computer by GPRS or USB. The information can be processed in computer, and show the result based on GIS.The nuclear prospecting data collection and processing system consists of the nuclear radiation multi-channel analyzer, data collector and data processing system.The nuclear radiation multi-channel analyzer used microcomputer C8051F060 as control core. It is finished with the scheme of two ADC running together, bluetooth technology and temperature and humidity sensor. This analyzer can collect the 1024 radiation spectrum, temperature and humidity together. It can improve the resolution ratio and without link-wire. The data collector used smart mobile phone as platform. The software of multi-information collecting on Windows Mobile was designed, which can finish the spectrum collecting and simple analysis, GPS positioning, picture or video collecting and word picture collecting. The information can communicate with the computer by GPRS technology or USB interface.The data processing system run in the computer. The software was designed on Windows platform by using Geographic Information System module technology - MapObjects and adopting object-oriented programming language Visual C++. It includes the function modules,which are the pretreatment of nuclear prospecting data, data interface, map-plotting, the processing and management of map layeres and so on. A visualization method of nuclear surveying data using the Google Earth is also introduced in the paper.The nuclear prospecting data collection system is portable, and the whole system merges multi– information into an organic whole. It makes full use of the resource, and is efficient, high precision, multi-informational, map overlying on GIS.
