The Research Of Vehicle Traveling Data Recorder System Based On3G Technology

Vehicle traveling data recorder is a device that is different from the traditional vehiclenavigation system, belongs to the national legal norms of public safety products. Vehicletraveling data recorder can record and output vehicle speed, braking and other driving data,thus providing valid credentials for the post identified accidents, can effectively regulatevehicles and drivers, improve traffic management and law enfo rcement level. However, thecurrent record data is likely to be damaged, security is not high, and the stand-alone datarecording is a bit thin on the function. This paper presents a vehicle traveling data recordersystem based on3G technology, which combines database technology and uppermanagement software, This system can improve data security, and it is easy to be usedtraffic for the management personnel to manage and use the recorder data over the Internet.This paper introduces the principle of3G technology and embedded systems, describethe design of vehicle traveling data recorder system related PC software system and vehicleembedded terminal program in detail. Vehicle terminal use an i.MX536as the maincontroller, which reads data from the GPS module and other modules, and then sent to theupper system by the3G module. Completed a blind compensation function to ensure thatdata can’t lost when there is no signal, and intelligent data upload algorithm is designed toavoid unnecessary waste of bandwidth resources3G. With the SSH framework as the uppermanagement software framework, developed a fully functional database. Achieve the roleof management, vehicle registration and vehicle data query functions.
