【摘要】：POS(Position and Orientation System)系统,即定位定姿系统,是由惯性测量单元IMU (Inertial Measuring Unit)和全球定位系统GPS (Global Position System)组成。 随着科学技术的高速发展,POS系统的应用也越来越广泛,同时更多领域对其性能也提出了更高的要求。但是由于POS系统昂贵的价格,使得基于POS系统的一些高精度和高性能的设备的研发成本大大提高。为了使POS系统能够在实现基本功能的情况下最大限度的节约成本,本文对其硬件控制进行研究设计。 文中详细的介绍了POS系统的基本构成,并从其基本构成着手,完成了系统的设计。系统以ARM嵌入式处理器S3C6410为基础,通过加速度计JHT-I-A和陀螺仪VG035P来获取当前的三轴的加速度和角速度信息,然后采用了AD7687BRM模数转换芯片进行模数信号的转换,通过Altera公司Cyclone Ⅲ系列FPGAEP3C40Q240将六路的信息数据并行采集并上传给主机处理系统,同时利用NovAtel公司的GPS板卡完成系统的授时,最后通过ARM将数据传递给PC机进行后续的处理。 本文详细的论述了整个POS系统的总体方案设计和软硬件的实现,同时给出了系统在静态测试时的测试结果。从测试结果可以看出,系统基本完成了设计的功能。
[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，
