Intelligent obstacle avoidance lifting hook of tower crane and control system thereof

Abstract

The invention discloses an intelligent obstacle avoidance lifting hook of a tower crane and a control system thereof. The lifting hook and the control system thereof comprise a lifting hook, a central control processing module and mobile terminal equipment, wherein the lifting hook comprises a lifting hook body, an obstacle avoidance processing unit, a first communication unit, a first alarm unit and a first power supply; the central control processing module comprises a processor unit, a sensor unit, a mechanism driving unit and a second power supply; and the mobile terminal equipment comprises an equipment shell, an industrial control touch display screen, a control handle, a second communication unit and a second alarm unit. According to the intelligent obstacle avoidance lifting hook of the tower crane and the control system thereof provided by the invention, by utilizing a binocular depth-of-field camera, a laser distance measuring sensor, height sensing equipment, other sensing equipment and a high-performance microprocessor, real-time map construction and positioning are realized, an optimal transportation path is automatically planned, and obstacles are autonomously judged and avoided, so that the number of operators is reduced, the construction efficiency is improved, the design is scientific, and the system stability is high.

Description

technical field [0001] The invention relates to the field of tower crane auxiliary technologies, in particular to an intelligent obstacle avoidance hook of a tower crane and a control system thereof. Background technique [0002] As one of the important tools for vertical and horizontal load transportation in construction, tower crane (referred to as tower crane) has the characteristics of large lifting capacity, high height and long amplitude. With the full rollout of national infrastructure, high-rise buildings are becoming more and more dense, and the frequency of cross-operation of tower cranes between various construction sites and between multiple tower cranes is also increasing. During the operation, the tower crane may not only collide with known obstacles (such as tower cranes, buildings, etc.), but may also collide with unknown and sudden obstacles (such as people, temporarily piled materials, etc.) ) produces collisions and scratches, which poses a greater potent...

AI Technical Summary

Problems solved by technology

[0007] Although the above existing technologies can achieve a certain degree of automatic path planning and obstacle avoidance, the frequency of path confirmation requires personnel to participate, and manual confirmation is required every time an obstacle is encountered. After the "automatic stop", the re-planned path is determined and executed by humans; the environmental data measurement equipment is installed on the luffing trolley, and the distance of the hoisting weight and obstacles is too far to measure, and there is a certain lack of accuracy; emergency braking through the jet device is prone to failure Unbalanced force on the hook, resulting in safety accidents such as rotation and scattering of hanging objects
