【摘要】：指南針自古以來就是人們導(dǎo)航定向的重要工具。隨著科技的發(fā)展,電子羅盤逐漸替代傳統(tǒng)指南針,廣泛應(yīng)用于航海航天,探險(xiǎn)勘測(cè)等領(lǐng)域。在各種導(dǎo)航技術(shù)蓬勃發(fā)展的今天,電子羅盤產(chǎn)品以其獨(dú)有的優(yōu)良特性,在導(dǎo)航定向方面仍作為基本的工具被廣泛使用�；谶@一背景,本文采用各向異性磁阻傳感器作為磁敏感元件對(duì)電子羅盤系統(tǒng)進(jìn)行相關(guān)的研究。主要研究內(nèi)容如下:本文以實(shí)現(xiàn)一種小型化,便攜化,精度在3°以內(nèi),可以滿足一般民用需求的電子羅盤為研究目標(biāo)。首先,研究基于電子羅盤測(cè)量原理,根據(jù)羅盤系統(tǒng)預(yù)期性能指標(biāo),在硬件上主要開展了方案設(shè)計(jì)、芯片選型、電路設(shè)計(jì)、功能驗(yàn)證、參數(shù)調(diào)整等工作,實(shí)現(xiàn)了對(duì)電子羅盤航向角計(jì)算的必要信息的采集;其次,為匹配硬件的設(shè)計(jì),在軟件及數(shù)據(jù)提取上開展了實(shí)現(xiàn)軟件濾波算法、誤差補(bǔ)償校正算法和航向角計(jì)算工作。經(jīng)過軟件濾波算法處理,數(shù)據(jù)中干擾成分得到抑制,采樣曲線平滑。數(shù)據(jù)補(bǔ)償算法明顯提高了航向角輸出精度。最后,研究搭建了基于各向異性傳感器的電子羅盤樣機(jī),該電子羅盤系統(tǒng)在水平狀態(tài)下,0°~360°范圍內(nèi)航向精度測(cè)量平均誤差為2°,在傾角±30°的范圍內(nèi),羅盤仍可正常工作并且滿足精度要求。
[Abstract]:The compass has been an important tool for people's navigation and orientation since ancient times.With the development of science and technology, electronic compass is gradually replacing the traditional compass, widely used in navigation, exploration, and other fields.With the rapid development of various navigation technologies, electronic compass products are still widely used as basic tools for navigation and orientation due to their unique excellent characteristics.Based on this background, an anisotropic magnetoresistive sensor is used as a magnetic sensor to study the electronic compass system.The main research contents are as follows: the aim of this paper is to realize a kind of electronic compass with miniaturization, portability, accuracy less than 3 擄, which can meet the general civil needs.First of all, based on the electronic compass measurement principle, according to the expected performance index of the compass system, the main hardware design, chip selection, circuit design, function verification, parameter adjustment and other work are carried out.The necessary information of calculating the heading angle of electronic compass is collected. Secondly, for the design of matching hardware, software filtering algorithm, error compensation correction algorithm and course angle calculation are carried out in software and data extraction.After processing by software filtering algorithm, the interference components in the data are suppressed and the sampling curve is smooth.The precision of heading angle output is improved obviously by the data compensation algorithm.Finally, the prototype of electronic compass based on anisotropic sensor is built. The average error of course measurement is 2 擄in the range of 0 擄~ 360 擄and 鹵30 擄in the range of inclination.The compass can still work properly and meet the precision requirements.
