基于激光测距传感器的汽车防撞报警器的设计

The Design of the Vehicle Anti-collision Alarm Apparatus Based on Distance Laser Sensor

介绍了一种基于激光测距传感器的汽车防撞报警器的设计原理。在车体上合理布置这些传感器,利用反射激光测量待测距离,实现汽车前行和倒车时对障碍物距离的检测、实时显示和报警,使汽车避免和障碍物发生碰撞。实践表明该汽车防撞报警器具有测距速度快、准确度高、易于实现等优点,具有很好的应用前景。

This thesis recommends the designing principle of alarm apparatus for preventing the automobile colliding base on distance laser sensor. In the automobile exterior reasonable installment these sensors, the system achieves to detect obstacle the distance and display the distance and alarm when the automobile is going forward, or bachward, preventing the automobile colliding from obstacle. By the experiment, the apparatus has a speediness of distance measurement, high accuracy, advantage of realizing easily etc. It has a good practical future.
