Highway Collision Prevention Alarm System Sensors And Power

With the rapid development of freeway, freeway safety is becoming more and more serious. At the same time ITS present new challenge to researchers over the world. To solve our country's safety problem, we research and design a suit of preventing Rear-end collision warning system. The main goal is to get more reaction tune and reduce traffic accident number.This paper research the relationship between driver and accident. Based on warning calculation model, analyze all sensors used in this system and present speed calculation method. Considering other sensors operating characters, propose their design schematic and using. Design a unit of information sampling to get all information of operating condition and automobile's characters. All these reduce response tune and virtuous warning. Analyze the electronic character of system operation and present supplying voltage protection. This method improved the reliability of system.
