Tips: Application of laser sensor - Automatic Collision Avoidance System
In general, most existing automatic collision avoidance systems use laser distance sensors. The laser sensor uses a laser beam to identify the distance between a car and a target car driving in front or behind it in a non-contact manner. When the distance between the cars is less than the predetermined safe distance, the automatic collision avoidance system of the car makes an emergency brake on the car, or issues an alarm to the driver. The car collision avoidance system can make real-time judgment and response to the car driving by integrating the target car speed, car distance, car braking distance, response time and other factors, which can greatly reduce driving accidents. Especially when used on the highway, the advantages of the car collision avoidance system will be more obvious.
Low price laser sensor has rectangular ABS housing with small outer size 22*11*31mm, laser spot size 1mm, power supply 10-30VDC, protection class IP67, can be used for object presence/ distance/ contour measurement, material/ liquid level detection and control, linearity correction, vehicle wheel speed/ vibration/ bounce measurement. The rectangular diffuse reflection type and through beam type laser sensor have respective detection range of 200mm/50m.
