本科毕业设计 基于单片机的汽车行驶状态记录仪 摘要 ：Based on SCM of automobile driving state recorder Abstract Car driving recorder, commonly known as the automobile black box, it is the vehicle speed, time, mileage and vehicles other status information recording and storage can be realized through the interface and the data output of the digital electronic recording device. At present all over the country passenger transportation companies, logistics companies, tourism companies and dangerous goods transport companies, bus group, and all enterprises and institutions in the nervous and orderly to install the car recorder. State in this paper, first of all, on the car recorder has carried on the simple introduction, analyzed the research background and significance of vehicle data recorder, illustrates the research level and development trend at home and abroad; Secondly puts forward the system of scheme design; Followed by the hardware circuit design of the vehicle data recorder, including the power supply module, signal acquisition module, MCU module, keyboard module, memory module, display module, clock module, alarm module, etc.; The last is the program design of several major vehicle data recorder software, including signal acquisition program, data storage, parking preprocessing procedures, etc. Due to its portability vehicle data recorder, reliability, versatility, in road safety, traffic law enforcement, transportation management plays an important role. Start construction process of intelligent transportation systems, along with our country will become the vehicle data recorder to ensure that the modern transportation safety and efficient dynamic operation management an integral part of logistics.
