Aiming at problem of tower crane anti-collision

a detector for obstacle detection is designed. Based on principle of ultrasonic distance measurement

detector can automatically detect obstacles close to tower crane arm and send alarm message. System composition

operation mode

detector structure design and installation are illustrated indetail

design result is verified by Matlab simulation. The design broadens detection range

and closed three-dimensional protection zone around tower crane arm is formed through multiple nodes arrangement

that avoids accident effectively and it is of great significance for safe operation of tower crane.
