Embodiment
[0049] The anti-collision early warning method of the cable crane hook described in the embodiment of the present invention, as figure 1 shown, including the following steps:
[0050] Step S1. Determine the highest dam section and the maximum height H of the highest dam section from the ground of the cable crane construction dam max and the first coordinate set B of each boundary point of the highest dam section (B 1 , B 2 ,...,B n ), the first coordinate set contains the first coordinate B of each boundary point of the highest dam section k (x 1k ,y 1k ,z 1k );
[0051] Such as figure 2 As shown, the cable machine described in this embodiment includes a suspension hook, a main tower and an auxiliary tower connected with the main tower by a traction rope, and the suspension hook is suspended on the traction rope. Among them, the highest dam section of the construction dam section can be determined according to the actual situation of the construction site, and its co...

The present invention relates to the field of cable cranes. The invention aims to solve the problems of poor accuracy and timeliness in the existing anti-collision methods for cable cranes, and proposes an anti-collision warning method and system for cable crane hooks. The method includes the following Step: determine the first coordinate set of the highest dam section, the maximum height of the highest dam section from the ground, and the boundary points of the highest dam section of the cable crane construction dam; obtain the second coordinates of the hook in real time, and calculate the relationship between the hook and the highest dam section. The real-time height difference of the dam section; on the XY plane, calculate the distance between the hook and each boundary point of the dam section, and determine the boundary point of the dam section closest to the hook on the XY plane and the corresponding first minimum distance; When the real-time height difference is less than a first preset value and the first minimum distance is less than a second preset value, an early warning message that the hook is about to collide is sent. The invention can send early warning information when the cable crane hook may collide with the highest dam section, thereby ensuring the safe operation of the cable crane.
Description
technical field [0001] The invention relates to the field of cable cranes, in particular to an anti-collision warning method and system for a cable crane hook. Background technique [0002] In the construction process of water conservancy projects, especially concrete dams such as arch dams and gravity dams, the cable crane is an important transportation equipment for concrete construction. Its safe and efficient operation not only directly determines the construction progress of the dam, but also affects the operators It is an important task of construction management to ensure the personal safety of the cable machine and ensure the safe and efficient operation of the cable machine. However, the operation safety of the cable machine is affected by factors such as strong winds in the river valley and large installation spans. The situation that the swing of the hook is too large occurs from time to time, and the safety distance control of the cable machine is not in place or...
