【摘要】：POS(Position and Orientation System)系統(tǒng),即定位定姿系統(tǒng),是由慣性測量單元IMU (Inertial Measuring Unit)和全球定位系統(tǒng)GPS (Global Position System)組成。 隨著科學(xué)技術(shù)的高速發(fā)展,POS系統(tǒng)的應(yīng)用也越來越廣泛,同時更多領(lǐng)域?qū)ζ湫阅芤蔡岢隽烁叩囊�。但是由于POS系統(tǒng)昂貴的價格,使得基于POS系統(tǒng)的一些高精度和高性能的設(shè)備的研發(fā)成本大大提高。為了使POS系統(tǒng)能夠在實現(xiàn)基本功能的情況下最大限度的節(jié)約成本,本文對其硬件控制進(jìn)行研究設(shè)計。 文中詳細(xì)的介紹了POS系統(tǒng)的基本構(gòu)成,并從其基本構(gòu)成著手,完成了系統(tǒng)的設(shè)計。系統(tǒng)以ARM嵌入式處理器S3C6410為基礎(chǔ),通過加速度計JHT-I-A和陀螺儀VG035P來獲取當(dāng)前的三軸的加速度和角速度信息,然后采用了AD7687BRM模數(shù)轉(zhuǎn)換芯片進(jìn)行模數(shù)信號的轉(zhuǎn)換,通過Altera公司Cyclone Ⅲ系列FPGAEP3C40Q240將六路的信息數(shù)據(jù)并行采集并上傳給主機處理系統(tǒng),同時利用NovAtel公司的GPS板卡完成系統(tǒng)的授時,最后通過ARM將數(shù)據(jù)傳遞給PC機進(jìn)行后續(xù)的處理。 本文詳細(xì)的論述了整個POS系統(tǒng)的總體方案設(shè)計和軟硬件的實現(xiàn),同時給出了系統(tǒng)在靜態(tài)測試時的測試結(jié)果。從測試結(jié)果可以看出,系統(tǒng)基本完成了設(shè)計的功能。
[Abstract]:POS (Position and Orientation System) system is composed of inertial measurement unit (IMU (Inertial Measuring Unit) and global positioning system (GPS (Global Position System). With the rapid development of science and technology, the application of POS system is becoming more and more extensive. At the same time, more and more fields put forward higher requirements for its performance. However, due to the expensive price of POS system, the research and development cost of some high-precision and high-performance equipment based on POS system is greatly increased. In order to realize the basic functions of the POS system to maximize the cost savings, the hardware control of the system is researched and designed in this paper. In this paper, the basic structure of POS system is introduced in detail, and the design of the system is completed. Based on the embedded processor S3C6410 of ARM, the acceleration and angular velocity information of the current three-axis are obtained by accelerometer JHT-I-A and gyroscope VG035P, and then the analog-to-digital signal is converted by using AD7687BRM analog-to-digital conversion chip. The six channels of information data are collected in parallel and uploaded to the host computer processing system through the Cyclone 鈪，
