Embodiment 1

[0048]The invention discloses a real-time navigation system for crane operation, which includes a path planning unit, a human-computer interaction unit, a boom attitude detection unit and an obstacle collision detection unit; Plan the jib movement path with the received coordinates of the target hoisting object, and obtain the jib movement sequence and target point position; among them, the jib movement includes luffing and landing, boom telescoping, left and right rotation, and hoisting; human-computer interaction The unit is used to set the coordinate information of the target hoisting object, and display the action path and the position of the target point in the form of graphics and text; the jib attitude detection unit is used to detect whether the jib during the action is in danger of collision; obstacle collision The detection unit is used to detect whether the boom in motion exceeds the position of the target point.

[0049] The crane real-time navigation system provid...

Embodiment 2

[0065] This embodiment discloses a real-time navigation method for crane operations, the method is based on the system of Embodiment 1, and the method includes the following steps:

[0066] According to the environment model of the job site, the current attitude information of the boom and the received coordinate position of the target hoisting object, the movement path planning of the boom is carried out, and the movement sequence of the boom and the position of the target point are obtained; the movements of the boom include luffing and landing, telescopic boom, Turn left and right and hoist up.

[0067] Display the motion path and target point position in graphic form; control the boom to move to the target point position according to the motion path.

Abstract

The invention discloses a crane operation real-time navigation system and method. The system comprises a route planning unit, a man-machine interaction unit, an arm support gesture detecting unit andan obstacle collision detecting unit. When a lifting task exists, the system can automatically plan a crane motion path and display a motion and a target point which are about to be executed currentlyand a motion and a target point which need to be executed at a next stage on a man-machine interface, so that graphic guiding of operators can be achieved. When a certain sub-motion is executed, thesystem detects an obstacle, or when a certain sub-motion passes the target point, the system can plan the motion path again and update the path in time on the man-machine interface, and safe transferof lifted objects is ensured.

Description

technical field [0001] The invention relates to the technical field of crane operation navigation, in particular to a crane operation real-time navigation system and method. Background technique [0002] Cranes are widely used in urban building construction, bridge construction, high-altitude equipment installation and other occasions. The hoisting operation environment is complex, and there are often occasions where multiple obstacles are affected and hoisting in a small space. During the hoisting operation, due to poor communication and poor vision between the operator and the commander, collision accidents often occur during the hoisting process. With the development of cranes in the direction of intelligent operation, the control system can build an environmental model of the job site in advance, plan the job path according to the location of the crane, hoisting objects, and obstacles, and guide the operator to work safely. However, since the job site environment is cha...
