The Design Of Data Recorder For Special Vehicles Based On Ethernet

Modern electronic and information technology is a major pillar of vehicle systems,including information technology, control the multiplier effect due to the role played by thegreat attention in particular. In a modern high performance vehicles, systems, informationtechnology, great impact on the level of efficiency of use of vehicles. Therefore, as the basisof information processing, vehicle information transmission within the system, informationprocessing, information storage is the first problem to be solved.This paper introduces the CAN bus and internet data recording of informationtransmission and the need for, and then explained the design principle of the data recorder-the technical requirements-Design and Implementation-Hardware Debug-softwaredebugging-System debug and describes the scene in the test based on vehicle. Final designconclusions are given.Design process, the first detailed analysis of vehicle systems for data recording thetechnical requirements, and basic working principle, according to technology requirements,develop the design; article sure to use ATOM+CFast design plan, so that the recorder has along time data storage, high-speed USB data communication features.Finally, describes thescene in the test system in the car when the data logger’s work, as of today the unit hascompleted all system integration testing and testing.
