Embodiment
[0112] Such as Figure 8 As shown, there are two tower cranes (TC1 and TC2) on the same construction site, and the anti-collision system of the present invention is installed on the tower cranes, and the coordinate positions of the construction site of the two tower cranes (in meters) (x1=0, y1=0 ), (x2=90, y2=0); the structural parameters of the two tower cranes are: the length of the front bridge of TC1 is 75 meters, the length of the rear bridge is 8 meters, and the height of the tower is 80 meters; the length of the front bridge of TC2 is 70 meters, and the length of the rear bridge The length is 8 meters, and the tower height is 60 meters. Let TC1 be the current active tower crane, and the rotation alarm angle is 20 degrees. The current position relationship of the two tower cranes is shown in Table 1.

The invention discloses a multi-tower-crane three-dimensional space anti-collision method based on behaviors. The multi-tower-crane three-dimensional space anti-collision method comprises the following steps: step 1, decomposing a movable part of a tower crane; step 2, taking behaviors as starting points of calculating and controlling and decomposing the behaviors of the tower crane in the working process into a rotation behavior of a cargo boom, an amplitude variation behavior of a trolley and a hoisting behavior of a hoisting hook; step 3, establishing a space model for a behavior track of the movable part of the tower crane; and step 4, carrying out interference calculation by utilizing an intersection algorithm of geometric figures in computer graphics; and carrying out initiative anti-collision control on the tower crane. The multi-tower-crane three-dimensional space anti-collision method based on the behaviors has the beneficial effects that a three-dimensional space posture model of a cantilever crane of the tower crane under each behavior is established in a way of the behaviors of the tower crane, further the interference calculation in the computer graphics is utilized to judge dangerous conditions of the behaviors of the tower crane and the initiative anti-collision control is carried out on the tower crane according to the conditions.
Description
technical field [0001] The invention belongs to the technical field of tower group safety control, and relates to a behavior-based three-dimensional space anti-collision method for multi-tower cranes. Background technique [0002] The construction of modern large-scale infrastructure is a production process in which multi-variety and multi-quantity construction machinery groups (various heavy machinery on the construction site), such as tower cranes (tower cranes), work together. These heavy machinery are characterized by large operating range, large mass, and large inertia. When performing corresponding tasks in a complex environment, they will appear in various configurations and attitudes in the operating space, and they are prone to collisions and other vicious accidents during collaborative operations. . The tower crane has a high center of gravity, a large lifting load, and a fast running speed. There are more risk factors in the work, and most of them are manually op...
