Abstract: Is day by day prosperous along with the social economy development transportation shipping industry, the auT0mobile quantity climbs in the first mate. Traffic congestion condition also day by day serious,the collision event occurred repeatedly, has caused the inevitable person casualties and the economic loss, in view of this kind of situation,designed one kind T0 respond quickly, the reliability was high also a more economical auT0mobile guards against hits the early warning system imperative, the ultrasonic wave range finding was the most common one distance range finder method, this article introduces is guards against using the ultrasonic wave range finding design one kind of back-draft hits the alarm system.
The paper is based on the contents of the AT89C51 monolithic integrated circuit reverse collision avoidance system design, mainly using ultrasound features and advantages, ultrasound ranging system and the integration with the integration AT89C51 monolithic integrated circuit, AT89C51 monolithic integrated circuit based on the design of a reverse collision avoidance warning systems. The system used software and hardware integrated approach of a modular and multi-use characteristics.
This paper, a simple distance measurement principle, a collision warning system, analyzes the design principle of reversing anti-collision system and the design of some components, fully describes the principles and application of ultrasonic distance measurement, and introduced China's current development in the ultrasonic ranging, but there are some unavoidable measurement errors, all need more advanced scientific development T0 be addressed.
Key wards AT89C51;ultrasonic distance measurement;a collision warning system
