Research On Automobile Anti-collision Alarming System Based On SPCE061A

With the continuous improvement of our country economy as well as the rapiddevelopment of the automobile industry, cars have become a very important mode oftransportation in people’s daily life and work. When we enjoy the convenience that cars bringus, the frequent ttraffic accidents which threat people’s lives and people safety are nothingnew now. Automobile safety has gradually become the focus of attention,so the research anddesign of anti-collision warning system have a goodd prospect of app1ication and econom.The thesis mainly analyzed deeply the research on the design of anti-collision warningsystem, according to the latest research focus in domestic and foreign countries,put forward acomprehensive and safety anti-collision warning system，which includes Rear-end Collisionand Side Collision warning systems.The system consisted of the Distance-MeasurementModule,Control Module, Information Collection Module,Display Module，Sound or LightAlarm Module and Voice Alarm Module. The paper discussed the scheme of these moduleand seleeted the best system scheme in the paper. In design of the software, according to thenewest research results and the actual needs of system, the paper had establishedcomprehensively, practical, the simple security anti-collision theoretical model. In detaildesign of the hardware, it presented the theory and characters of anti-collision warning systembased on the SPCE061A microcontroller.At last, the simulation and experiment wasintroduced into the system, and presented the result of the experiment. The main contents ofthis paper are as follows:(1) Finish the hardware design of the systems.In the system,SPCE06A works as maincontroller;Radar and Ultrasonic wave work as the ranging way.The paper constructs thehardware system and draws the principle diagram of Distance-Measurement module,Information Collection module, Voice Alarm module and so on.(2) Finish the software design of the systems.In this unit,using C language and assemblylanguage hybrid programming modle to achive the overall function of the system.The paperalso give the some program of the system,For example, the Distance-Measurement module,Voice Alarm Module and so on.(3) Establish the vehicle anti-collision model based on the whole situation. A collisioncalculating methods have been developed by analyzing the vehicle collision process. Itemerged that the methods owns an strong application, and it help to warn the drivers andbrake to secure their safety. Finally，based on summarizing the whole thesis, its weak points and further researchdirection are pointed out.In a word, the system has a simple structure, and the overall performance of which is stableand reliable, imitations of main cases have been carried out.The test result shows that thesystem run esstably on the car, and the ability of interference rejection is strong.
