Long-Distance Ultrasonic Ranging System Oriented to Tower Crane Anti-Collision

Abstract:

Aiming at existing problems about the tower crane anti-collision system at home and abroad, in-depth researches and experimental verification about long-distance ultrasonic ranging technique have been carried out. The design of hardware circuit and software program was completed. The functions such as ultrasonic emission, echo receiving, data acquisition were implemented. The algorithm of delay time estimation based on cross-correlation was researched. The experimental results show that long-distance ultrasonic ranging system can detect the long-distance obstacle (about 25m) effectively and reliably, thus laying technique foundation for the research of the tower crane anti-collision system.
