手机行车记录仪的开发

Development of Cell-Phone-Type Vehicle Traveling Data Recorder

设计了一种新型的手机式汽车行驶记录仪。在数据处理、信息显示以及数据存储方面,利用手机本身的处理器、LCD和SD卡替代了传统行车记录仪的相应功能部件。在数据传输方面,采用手机蓝牙与数据采集装置进行信息交换、命令传递,实现无线通讯。蓝牙具有特殊、普通两组服务,区分了系统用户和普通用户的访问权限。整个系统具有显示、车辆行驶参数记录与分析、数据保存与回放功能,实现了行车系统的便携化和无线化。

A new cell-phone-type vehicle traveling data recorder is designed. In the aspect of data processing, information display and data storage, it uses cell phone＇s processor, LCD and SD card instead of traditional vehicle traveling data recorder＇s corresponding components. In the aspect of data transmission, it uses Blueteeth to exchange information and order with the data acquisition equipment. It achieves wireless communication. Bluetooth has a special service and an ordinary service. It distinguishes accessing power between system user and guest user. The system could display, record and analyze parameters of vehicles, save and playback data of acquisition. It realizes. It makes the vehicle traveling data recorder portable and wireless.
