基于嵌入式汽车行驶记录装置的研制

Research on Vehicle Traveling Data Recorder Based on Embedded System

设计了一种以cotex-M4处理器为核心、μC/OS-II为操作系统的汽车行驶状态监控系统,对汽车行驶状态进行实时监测和记录,系统可以通过串口或USB接口进行参数设置和记录数据的转储,转储到PC机中的数据通过上层分析软件进行分析处理,从而为主管部门对车辆及驾驶员的管理和调度提供科学的依据,实验表明该监控系统完全符合国家标准。

This paper designed a kind of vehicle traveling data recorder with the cotex-M4 processor as the core and μC/OS-II as the operating system, which can monitor and record the driving state of the automobile in real-time. The system sets parameters and records the data dump through a serial port or USB interface. The data dumped to the PC are analyzed and processed by the upper analysis software. It can provide scientific basis and schedule to the department in charge of the management of vehicles and drivers. The experiment shows that the monitoring system is fully compliant with national standards.
