基于AT89C51的数字指南针设计与实现

Design and Implementation of Digital Compass Based on AT89C51

随着人民生活技水平的提升,人们外出旅游越来越多。本文设计的数字指南针系统,充分结合AT89C51芯片的性能特点,采用两个霍尔传感器作为地磁信息采集的核心部件,实现了对地磁信息的采集、放大,经过单片机处理,最终显示出用文字和语音表示的当前所处方位及当前地理位置的温度信息。

With the improvement of people's living skills, more and more people go out to travel. The digital compass system de-signed in this paper, fully combined with the performance characteristics of AT89 C51 chip, uses two Holzer sensors as the corecomponents of geomagnetic information collection, and realizes the acquisition and magnification of geomagnetic information. It hasbeen processed by single chip computer. Finally, it shows the current location and the current geographical position expressed inwords and speech. The temperature information is placed.
