The Development Of Multi-functional Gps Navigation Recording System

With the rapid development of China's economy, improve people's living standards, exploration, tourism has become a common way to relax. Tourism driven the rapid development of related industries, and various types of tourism-related electronic products are also popular tourist enthusiasts, contains enormous business opportunities. Positioning the trajectory precisely on the map and playback beautiful journey become more popular in Europe and the United States. And a powerful and easy to carry the related products have become the focus of the study in this area.First of all, an analysis of this topic GPS navigation applications record the significance of the status quo at home and abroad and the development direction of development, as well as the current GPS navigation recorder market products storage space, features a single problem, a innovative type of card multi-functional GPS navigation system logger.This product is innovative use of Micro SD card to store track information, increased data capacity and rapid reading stability. Can be used to record the voice of interest, it is easy to go out to the most interesting journey of the recording. Also designed the whereabouts of the potential record mode, in which low power consumption mode, it takes a long time to meet the needs of users in outdoor activities. Speeding alarm type can be set so that Self Drive Vacations more convenient and safe.Based on the above functional requirements, this article is based on a single chip PIC18F4620 with GPS receiver modules, Bluetooth modules, power management modules, etc. other auxiliary modules, designed to record this navigation structure of the program's hardware, details on the main circuit and the The hardware interface module circuit. Through the FAT 16 file system, Micro SD card format operation and WAVE audio files of research, completed a navigation recorder software code debugging, and finally achieve the PC-side track document conversion, integration of the entire system, the completion of established goals.Test proved that the system records the GPS navigation function deployment is one of the products relatively wide and easy to use, plug-in card recording and sound recording is very intimate, like to travel and hope to share their wonderful life users, definitely worth a try.
