With the rapid development of automobile manufacturing industry, traffic accidents are increasing year by year. The incidence of traffic accidents in China ranks first in the world for ten years in a row. In recent years, this number has declined. Thanks to the strengthening of investigation and punishment of drunk driving, and the improvement of punishment system, there are still some problems. In 2012, the safety problems of school buses were highlighted, and speeding occurred frequently. With the increase of the total number of cars, The traffic is more and more crowded, and the security situation is more and more severe. According to the statistics of relevant experts, when the economic development speed is more than 4% - 6%, the incidence of traffic accidents generally increases. In the development process of the automobile, automobile engineers mainly focus on the study of the passive safety of the automobile, such as: installing bumpers at the front and back of the automobile, installing airbags and safety belts in the automobile, etc., to reduce the injury caused by the automobile accidents to the passengers, but These measures do not play a role in reducing the probability of vehicle collision. In order to ensure the safety of the passengers, we can study the active safety in order to solve the safety problems.The focus of this topic is to understand the working principle of single-chip microcomputer and the research status and development trend of the existing automobile safety distance early warning system by consulting and reading a large number of domestic and foreign literature. The difficulty is the design of hardware schematic diagram and the programming of software.The specific contents and requirements are as follows:I. content:1. Understand the basic working principle of Single-Chip Microcomputer;2. Understand the basic principle of vehicle safety distance early warning system;3. Master the best scheme of Single-Chip Microcomputer Interface Circuit Design and hardware schematic design of vehicle safety distance warning system;4. Software programming based on hardware circuit diagram design;5. Carry out simulation experiment or hardware debugging for the designed vehicle safety distance warning system and analyze the experimental results;6. Put forward the prospect of future research.II. Requirements:1. Compile the design specification, with clear concept, comprehensive content, clear demonstration, neat writing, and design the circuit system and corresponding software programming that meet the requirements;2. Correctly and comprehensively apply the learned professional theoretical knowledge, collect the data required by the design, actively investigate, fully apply all kinds of relevant reference books and data, have the team spirit and the awareness of continuous independent learning and lifelong learning.III. Other requirements1. Litterateur review, 15 papers2. Thesis writing, more than 12,000 words.
