Research on Obstacle Avoidance Technology of Unmanned Crane Based on Ultrasonic Sensor
Aiming at the problem that obstacles cannot be accurately identified in the operation of unmanned crane,a method of automatic detection and avoidance of obstacles by ultrasonic sensor combined with PLC control is proposed.Through the horizontal and vertical installation of the sensor,the three-dimensional space in a full range of real-time monitoring without dead Angle.The sensor sends the obstacle information to the PLC system through the analog signal interface,and the PLC system controls the crane to make an accurate response in advance to avoid the obstacle according to the real-time position information,so as to ensure the safe,reliable and stable operation of the unmanned crane.
