Development And Application Of The New Vehicle Traveling Data Recorder

Vehicle travelling data recorder is a digital electronical apparatus which is used torecord data such as velocity, time and mileage and the other information relevant to thestatus of the vehicle. The data should be exported to the computer or other devices throughcommunication interface. The vehicle travelling data recorder means to maintain a store, ina secure form, of information concerning the relevant data, status of running over period upto and following an incident. On the one hand it is convenient for traffic managementdepartment as well as automobile operation unit for automobile manage; On the other handthe information of recorder record can still think the basis and that reason and just handlinghave offered science and authority that traffic accident occurs.First of all the paper describes the development, and the development tendency of thevehicle travelling data recorder. It expatiates on important significance of the vehicle datarecorder on the management of traffic and vehicle; the paper will introduce the mainfunction and the performance of the recorder, combine with the national standards ofvehicle travelling data recorder. And then, give the whole structure of the vehicle travellingdata recorder system and the selection of main functional module devices, which containsMCU and Clock Generator and RAM and GPS and interface of data communication.Finally, this paper elaborates software and hardware design of the vehicle travelling datarecorder, which is consist of bottom design and PC management and system PCB design,with an at large research on vehicle travelling data recorder's EMC, reaching the greatdevelopment of the security.The vehicle travelling data recorder of the paper has already passed the relatedMinistry of Public Security country standard examination, and has being performed stablyall right in the installation and experimental application, provided the effective safeguardfor the vehicles travel security and the traffic control department's monitoring.
