The Design of Vehicle Traveling Data Recorder Based on GPS/GPRS

摘要

Vehicle traveling data recorder (VTDR) is a "black box in vehicle" used for recording the vehicle speed, real-time, mileage and other status information. In this article, the hardware and software structures of the VTDR are described, including RFID authentication, data collection, data storage, data printing, serial and USB communication and LCD display. A global positioning system (GPS) module for tracking and position, a general packet radio service (GPRS) module for exchanging data between VTDR and vehicle management center are used in the VTDR. To extend the application of VDTR, this article also provides a solution of tracking, dispatch, bus station bulletin for a fleet of buses. It consists of vehicle management software based on geographic information system (GIS), buses with VTDR and electronic bus station board.
