How to strengthen the management of the vehicle, the driver39。s driving behavior norms, reduce traffic accidents, to create a harmonious, smooth traffic environment has bee an important issue for transportation and security administration faces.The main contents of this paper are: the use of GPS receivers, microcontrollers, memory devices, such as a vehicle designed to travel with positioning information recording system. Vehicle information recording system consists of a microcontroller MSP430F149 model consists of a control circuit, the information receiving circuit consists of a GPS receiver module, SD card reader module circuit. GPS receiver module receives GPS realtime data, parse through the MSP430 microcontroller, and latitude and longitude information extracted from the time needed to send through the serial port to the SD card for storage. SD card data will be created when writing txt file can be named, will receive the data stored in the named file.After several system debugging and experiments, the system can work properly designed, can achieve realtime vehicle location information records, thereby monitoring a vehicle traveling information.Keywords：GPS global positioning system。 MCU。 SD card。 information storage沈陽航空航天大學(xué)電子信息工程學(xué)院畢業(yè)設(shè)計（論文） III 目錄第 1 章 緒論 ..........................................................................................................................1 課題研究的目的和意義 ............................................................................................1 課題的主要研究內(nèi)容 ................................................................................................2 論文的組織結(jié)構(gòu) ........................................................................................................2第 2 章 系統(tǒng)分析與設(shè)計方案 ..............................................................................................3 GPS 系統(tǒng)及其工作原理 ............................................................................................3 GPS 基礎(chǔ) ............................................................................................................3 GPS 定位原理 ....................................................................................................3 GPS 數(shù)據(jù) ............................................................................................................4 系統(tǒng)總體設(shè)計 ............................................................................................................7第 3 章 系統(tǒng)硬件設(shè)計 ..........................................................................................................9 系統(tǒng)硬件總體設(shè)計概述 ............................................................................................9 系統(tǒng)電路模塊設(shè)計 ....................................................................................................9 MSP430F149 單片機簡介 ................................................................................10 MSP430F149 單片機最小系統(tǒng) ........................................................................14 GPS 定位信息接收電路 ..................................................................................16 SD 卡讀寫電路 .................................................................................................20 電源模塊電路 ...................................................................................................21 整體硬件電路 ..........................................................................................................22第 4 章 系統(tǒng)軟件設(shè)計 ........................................................................................................24 系統(tǒng)軟件總體設(shè)計概述 ..........................................................................................24 系統(tǒng)各部分程序 ......................................................................................................24 主程序 ...............................................................................................................24沈陽航空航天大學(xué)電子信息工程學(xué)院畢業(yè)設(shè)計（論文） IV SD 卡讀寫模塊程序 .........................................................................................25 GPS 數(shù)據(jù)處理模塊程序 ..................................................................................30第 5 章 系統(tǒng)調(diào)試與結(jié)果分析 ............................................................................................33 概述 ..........................................................................................................................33 IAR 軟件簡介 ..........................................................................................................33 軟件調(diào)試方法及步驟 ..............................................................................................34 系統(tǒng)在 IAR 軟件的調(diào)試 ..................................................................................34 程序下載電路的調(diào)試 .......................................................................................35 整體調(diào)試 ..................................................................................................................36 調(diào)試結(jié)果與分析 ......................................................................................................37第 6 章 經(jīng)濟與社會效益分析 ........................
