摘要
文中介绍了以PIC单片机为控制器的汽车行驶记录仪,能对汽车的GPS定位以及状态的采集,使用铁电存储器存储状态信号,通过RS232串口将数据传到上位机,进行分析和处理。系统可以对驾驶员的信息记录、采集开关量信号和模拟量信号,并具备存储、据通信等功能。软件方面使用access,降低了软件开发的难度、提高了系统的实时性和灵活性。
The paper introduces the vehicle data recorder with PIC single chip microcomputer as the controller. The vehicle data recorder can use the ferroelectric memory storage to store the state signals for the car GPS positioning and the state acquisition, transmit the data to upper computer through RS232 serial port so as to analyze and process the data. The system can record the driver＇s information, gather the switch signals and analog signals, storage and communicate the data. Using the access software, the recorder can reduce the difficulty of software development, and improve the real-time performance and flexibility of the system.
