Abstract
In recent years, as the economy continues to develop, car gradually into the huge market of household consumption, personal automobile consumption has become mainstream, the rapidly growing popularity of car consumption of the car, the vehicle traveling data recorder is a big space for development . Now vehicle traveling data recorder on the market presents a state of vigorous development, therefore, the design of the vehicle traveling data recorder were studied.
Design and implementation of vehicle speed, other status information time, mileage and vehicle-related basic functions of recording, storage, etc., and the integration of GPS (Global Positioning System) technology, GSM / GPRS communications technology and other high-tech, implemented as user provide real-time positioning, video surveillance, speed alarm, burglar alarm and other useful advanced features.
Design discusses in detail the design and implementation of vehicle recorder system hardware and software. Design introduces the research background, research status and domestic and foreign cars recorder summarized, on the basis of the contents of the proposed research topic. The hardware design uses TI's low-power America's MSP430F149 single chip microcontroller, vehicle traveling data recorder based on the requirements of the system's control module, speed module, GPS positioning module receives, GSM / GPRS communication module and burglar alarm and other modules of the design, and the final plan was described and details of implementation with the principles of the major functional components. Software designed to IAR for MSP430 development platform, with C language programming language with powerful debugging capabilities msp430 microcontroller design utility. Software design flow chart of the detailed description of each module, and part of the heavy and difficult module gives the design process. Finally, from a technical point of view the design are summarized.
Keywords: MSP430F149 microcontroller GPS GSM / GPRS Low power consumption
