Tower crane anti-collision system based on ultra wide band positioning and double-current network identification technology

Abstract

The invention discloses a tower crane anti-collision system based on an ultra wide band positioning and double-current network identification technology, which comprises an ultra wide band positioning module used for sensing the distance of a plurality of ultra wide band positioning labels arranged on different tower cranes and judging the relative distance between the tower cranes in real time; the double-flow network identification is used for identifying and tracking targets around the tower crane and providing auxiliary support; the intelligent decision-making mechanism module is used for carrying out collision early warning according to the sensing distance of the ultra wide band positioning module and carrying out dynamic basis and motion trend judgment on moving targets around the tower crane. According to the invention, by setting a plurality of label points and calculating information intensity early warning among point cloud labels formed by the plurality of label points of different cranes, multi-modal sensing and identification can be carried out on targets around the tower crane through an ultra-wideband positioning and double-flow network identification system, surrounding obstacles can be found in time, and the accuracy of the detection result is improved. And powerful technical support is provided for preventing collision of tower crane equipment.

Description

technical field [0001] The invention belongs to the technical field of intelligent control, and more specifically relates to a multi-tower crane simultaneous construction anti-collision system and method. Background technique [0002] At present, with the rapid development of my country's economy, there are more and more infrastructure projects. Tower cranes are a common construction equipment on the construction site. It can cause the tower crane equipment to collide with other equipment. In addition, since there are many cases of simultaneous construction of multiple tower cranes on the construction site, this puts forward higher requirements for the operators. If the operators make mistakes in judging the space distance, or make mistakes in operations due to blind areas of vision, personal injuries and property losses are prone to occur. [0003] The Chinese patent with the publication number CN 204778521U discloses "an ultrasonic-based visual tower crane collision warnin...

Problems solved by technology

In addition, since there are many cases of simultaneous construction of multiple tower cranes on the construction site, this puts forward higher requirements for operators. If the operator makes a mistake in judging the space distance, or makes a wrong operation due to the blind area of ​​vision, it is easy to cause personal injury and property loss.

[0003] The Chinese patent with the publication number CN 204778521U discloses "an ultrasonic-based visual tower crane collision warning device", which outputs different alarm sounds according to different ranging signals collected by the ultrasonic ranging unit for grading alarm prompts, To solve the visual blind spot of the tower crane operator, but this technology only uses ultrasonic detection, the detection area is limited, and it cannot dynamically track and warn the danger of the target in the tower crane construction area
