The Research And Design Of Popular Vehicle Travelling Data Recorder

As the rapid development of our national economy, the car is becoming more and more popular in our daily lives, and traffic accidents are also increasing very quickly, especially fatal traffic accidents among long-distance passenger cars, all these accidents do great damage to our lives and property. For this reason, vehicle travelling data recorder is widely used in developed countries. Through the use of vehicle travelling data recorder, we can restrict continuous driving, overspeed and other kinds of traffic peccancy. It is great benefit for improving of traffic saft and appraisal of traffic accidents. So now traffic control department of our country and police department etc. are making great effort to generalize the use of vehicle travelling data recorder to improve traffic control level of our country.On this background, Suzhou Bradford Electronics Co., Ltd. and Automatic Control Department of Southeast University take on the key technology project of Suzhou to develop popular vehicle travelling data recorder. The main purpose of us is to design and produce a kind of popular vehicle traveling data recorder that has economic cost and most of the universal functions.When I was doing the thesis, I finished the design of softwares and hardwares of vehicle traveling data recorder, and the work of debugging and test run of the sample instrument. The recorder has the core of 8-bit MCU (MCS51 Serials), and the cost is very competitive. It is really a kind of production that has high cost performances. In this paper, we focus on the scheme argumentation and selection of the recorder, hardware, software and communation design, questions met during debugging and solutions etc. The whole processing of vehicle traveling data recorder design has been discussed in detail in this paper.
