【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。更多还原

【Abstract】 The development of the GPS has brought profound changes into navigation field. Countless users worldwide rely on it to achieve accurate longitude and latitude, time and speed information. Especially in recent years, with the development of the embedded technology, the volume of the embedded processor is getting smaller and smaller, the performance is getting stronger and stronger, the function is getting more and more multitudinous, the price is getting lower and lower.In this situation, GPS technology based on embedded platform also will be applied to wider and broader areas, such as the moving route record, vehicle navigation, tracking and so on. The GPS electronic products have been deeply into people’s daily lives.The research supports the enterprise demand. GPS-Based Micro Route-recorder is just required. The Micro Route-recorder will be used to track suspicious persons with the potential danger to the national security.GPS products for the track record available in the market are mostly attached to the phones or tablet computers. These products are inadequate on positioning accuracy and also sensitivity. And using mobile phone will consume large electricity. Meanwhile, professional GPS Route-recorder is relatively a little larger in the size, lack of capacity, most important of all, is not conducive to do long working hours, so the battery life is also a problem. In conclusion, the research focus on a new product, which is set of size, positioning accuracy, sensitivity, endurance, power consumption, large capacity storage and easy to operate.For Micro Route-recorder, STM32is used to be as microcontroller, UC430, the world’s smallest chip, as GPS receiver. By the Route-recorder, the parsed data is successfully written into the SD card. After the file format is converted from SD card to Google earth, the recorded route is clearly displayed on Google earth. Based on this, some meaningful work such as route playback, suspect data analysis and so on can be carried out.更多还原
