| Vehicle traveling data recorder is a kind of electronic device that can collect and store thespeed, mileage, time and other vehicle-related status information and it can also achieve thegoal of data upload and download through the communication interface. It plays an importantrole to ensure traffic safety and road accidents, liability analysis, and it plays a supervisoryrole to the driver.This design firstly introduces the background knowledge of the vehicle traveling datarecorder, and a recorder with MSP430microcontroller as the core, and the vehicle travelingstate signal acquisition and processing, and storage capabilities is designed on the basis of therelevant national standards requirements.First of all, the vehicle traveling data recordercollects the signals of turns, brake, speed and other signals in the vehicle, and then the data isprocessing through the host controller MSP430F149ultra-low power microcontroller, and theprocessed data is stored in the FM24C04ferroelectric memory, which can guarantee that thevehicle traveling data recorder can still maintain the integrity of real-time data even in aserious accident, thus the reliability and safety of the system have been greatly improved. Thedesign of the host computer information analysis software is designed in Visual C. Thevehicle traveling data recorder communicates with the host computer via RS-232serial port torecord these data processing and analysis through data analysis and processing software forreal-time data recorded. |
