【摘要】：GPS的发展给导航领域带来了深刻的变化。全球范围内无数用户依赖它来为自己提供精确的经纬度、时间和速度信息。特别是近年来,随着嵌入式技术的跟进,嵌入式处理器的体积越来越小、性能越来越强、功能也越来越多,价格也越来越低,基于嵌入式平台的GPS技术也随之被应用到更宽更广的领域,如移动轨迹的记录、车辆导航、跟踪等各个方面。GPS的电子产品已经深入到人们的日常生活中。市面上用于轨迹记录的GPS产品,大多依附在手机或是平板电脑,定位精度不高,灵敏度方面也显不足,而且使用手机费电也非常大。而专业的GPS轨迹记录仪尺寸还是比较大,容量不足,不利于长时间工作,而且电池续航也是个问题。所以就需要开发一款集尺寸、定位精度、灵敏度、续航、功耗、大容量存储且操作简便于一身的GPS微型轨迹记录仪。论文源自于企业的需求,研发一个微型轨迹记录仪,用于特定人员、特定车辆轨迹的记录与回放。此微型轨迹记录仪采用STM32为微控制器,选用目前全球最小的芯片UC430为GPS接收机。经过大量的工作,实现了GPS数据的解析处理,并成功地写入到了SD卡里面。将SD卡中的txt格式的文件通过专门的工具转化为Google earth格式之后,所采集的数据在Google earth上成功地展现了出来。在这个基础上,专业人员就可以开展诸如轨迹回放、疑点数据分析等相关有意义的工作。
[Abstract]:The development of GPS has brought profound changes to the navigation field. Countless users around the world rely on it to provide themselves with accurate longitude, latitude, time and speed information. Especially in recent years, with the development of embedded technology, The size, performance, function and price of embedded processor are becoming smaller and smaller, so GPS technology based on embedded platform has been applied to a wider and wider field, such as track recording, vehicle navigation, and so on. Tracking and other aspects of GPS electronic products have penetrated into people's daily life. Most of the GPS products on the market for track recording are attached to mobile phones or tablets. The positioning accuracy is not high, the sensitivity is not high, and the use of mobile phones costs a lot of electricity. And the size of the professional GPS locus recorder is still relatively large. The lack of capacity is not conducive to long working hours, and battery life is also a problem. Therefore, it is necessary to develop a GPS microtrack recorder with size, positioning accuracy, sensitivity, endurance, power consumption, large capacity storage and easy operation. Based on the demand of the enterprise, this paper develops a micro track recorder for recording and replaying the track of a particular person and a specific vehicle. This micro track recorder uses STM32 as a microcontroller. UC430, the smallest chip in the world, is chosen as the GPS receiver. After a lot of work, the analysis and processing of GPS data are realized. After the txt file in SD card was converted into Google earth format by special tools, the collected data was successfully displayed on Google earth. Professionals can do relevant and meaningful work, such as track playback, suspect data analysis, and so on.
