基于SD卡的GPS轨迹记录仪研究设计

Research and Design of GPS Route Recorder on SD Card

以STC12LE5A60S2单片机为核心,通过连接GPS接收模块、SD(Secure Digital Memory Card)卡、显示及语音等模块实现对行车轨迹等参数的记录。对该记录仪的组成部件、功能及其软件和硬件的设计思想进行了阐述和说明。该记录仪可在行驶的过程中实时记录下车辆、船舶的行驶轨迹。根据设置的位置和速度信息,可实时检测并自动语音提示,设置位置、速度信息及语音信息方便修改,并能通过USB通信总线与PC机进行数据交换,记录的信息可用于车辆、船舶行驶过程的重现和分析。具有存储容量大,断电不丢失数据,使用方便等优点。

Have the STCI2LE5A60S2 MCU as the core, the recorder can achieve the record of parameters, such as the running track, by the connecting of GPS module card, SD card, LCD and voice module. And the recorder＇ s composition, function and the design idea of its hardware and software are elaborated and explained. This recorder can record real-time running track of vehicles or ships. According to the setting of position and velocity, this recorder can also provides real-time detection and automated voice prompts. The setting of position, velocity and voice information can be modified conveniently, and which can be exchange with PC through the USB communication. In addition to that, the recorded information can be used for the reproduction and analysis of the vehicles and ship＇ s process of moving. This recorder has large storage capacity, without loss of data even if power off, and easy to use.
