摘要
提出一种多功能汽车记录仪的设计方案,系统采用AT91SAM9260型ARM处理器为控制器,Linux操作系统,K91G08U0B型Nand Flash为存储介质,通过ET-318 SiRF StarⅢGPS芯片组接收GPS信号进行定位,而GPRS模块采用SIM300C传输数据。该汽车记录仪能够实时记录监测汽车行驶状态、位置,通过GPRS将行驶记录及当前信息上传至服务器,实现远程监控,具备超速、疲劳驾驶报警功能。数据可以通过USB或RS-232串口上传至上位机。经测试该记录仪性能稳定可靠。
The system used AT91SAM9260 ARM processor as the controller, and the linux operating system, and Samsung KglGO8UOB NandFlash as the torage medium. Through the ET-318 SiRF Star 3 GPS chipset, the system received GPS signals to locate. GPRS modules SIM300C was used to transfer data. The running state and the location of automobile could be monitored and recorded. By GPRS the driving records and current information will be uploaded to the server to achieve remote monitoring. This system also had darm function to reind the overspecd and fatigue driving recorded data could be transferred to computer through USB or RS-232. The practice proved that the device has steady performance and good effect.
