電子指南針畢業(yè)設(shè)計(jì)論文

1、青島理工大學(xué)琴島學(xué)院本科畢業(yè)設(shè)計(jì)說(shuō)明書(shū)（論文）I摘要早期的指南針采用了磁化指針和方位盤的組合方式，整個(gè)指南針從便攜性、指示靈敏度上都有一定不足，極易受到外界因素的干擾。本系統(tǒng)采用專用的磁場(chǎng)傳感器結(jié)合高速微控制器（MCU）的電子指南針能有效解決這些問(wèn)題。系統(tǒng)采用了磁阻（GMR）傳感器采集某一方向磁場(chǎng)強(qiáng)度后通過(guò)MCU控制器對(duì)其進(jìn)行處理并顯示上傳，通過(guò)對(duì)電子指南針硬件電路和軟件程序的分析，闡述了電子指南針基本的工作原理及實(shí)現(xiàn)。實(shí)際測(cè)試指南針模
