针对当前矿产资源分布系统存在定位范围小、精度低及比特率低的问题,提出并设计了基于GIS矿产资源分布区域定位系统。通过分析定位系统构架原理,对定位系统进行预处理；系统硬件主要包括SJA1000芯片、CAN总线、节点定位及晶振电路；通过搜索模型、信息量加权模型、定位数学模型组成系统软件部分,实现矿产资源分布区域定位。实验结果表明,该系统有效扩大了定位范围,提高了定位精度及比特率。

Regional positioning system of mineral resources distribution based on GIS

In order to solve the problems of low positioning range, low precision and low bit rate in the current mineral resources distribution system, a positioning system of mineral resources distribution area based on GIS is proposed and designed. Analysis of the positioning system principle through the system, the positioning system is pre treated; the hardware system includes SJA1000 chip, CAN bus, node location and oscillator circuit; through the search model, information model, weighted positioning mathematical model composed of system software, realize the distribution of mineral resources location. Experimental results show that the system effectively expands the positioning range and improves the positioning accuracy and bit rate.
