Abstract

The invention discloses an anti-collision pre-warning system and method for hoisting equipment. The anti-collision pre-warning system is based on a distributed type modular framework, and comprises aninformation collection system, an information transmission system and a field control system which are arranged in a distributed modularity mode, and all equipment and fixed obstacles are placed in the same coordinate system. The anti-collision pre-warning method includes the steps that the real-time position, the moving direction and speed information of moving parts of all the equipment are collected and preliminarily calculated by all the hoisting equipment in the field, then relevant information exchange is carried out, the probability of collision is calculated and pre-warning is carriedout, and the steps are cycled and repeated every 0.1 second. According to the anti-collision pre-warning system and method for the hoisting equipment, the distributed type anti-collision system framework is built, anti-collision calculation rules are made, the problem of collision among the hoisting equipment is decomposed into the problem of collision between the moving parts, a binary tree traversal recursive algorithm is adopted to ensure the prediction accuracy of the collision phenomenon, then the collision phenomenon is subjected to commonness processing, a collision pre-warning algorithm is compiled, and collision pre-warning is realized according to the anti-collision rules and algorithm compilation.

Description

technical field [0001] The invention belongs to the technical field of mechanical intelligent control, and in particular relates to an anti-collision early warning system for lifting equipment based on a distributed modular framework and a method thereof. Background technique [0002] Hydropower station construction and modern building construction rely heavily on gantry cranes. In order to improve construction efficiency, construction units often arrange multiple gantry cranes on the same site, and often cross-operate at close distances. Therefore, the coordinated operation of multiple large-scale lifting equipment Mutual interference is a common problem in terms of safety and operating efficiency. How to avoid collisions between devices and between devices and obstacles has become a problem that cannot be ignored. [0003] At present, research institutions and companies at home and abroad have carried out the development and application of anti-collision systems for large-...

Problems solved by technology

For the research on the anti-collision system of tower cranes in the field of construction, the existing technical methods are not compatible with the promotion and application of different types of tower cranes on the same construction site; The integration of simple functions such as limit, height limit, and angle limit, the anti-collision algorithm processing is relatively simple, and more focuses on the calculation of area restrictions, it is difficult to comprehensively and accurately predict the occurrence of collisions between tower cranes, and cannot meet the requirements of dam construction in water conservancy and hydropower projects. The need for different types of tower cranes to work in different environments; the existing system generally adopts a centralized system architecture, which requires the server to communicate with all devices in real time, and all anti-collision calculations and warning information predictions are performed on the server. Therefore, the system architecture communication chain The amount of road data is large, the calculation and processing of anti-collision are complicated, and the requirements for hardware are high. It is difficult to realize modularization, which is not conducive to the promotion and application of the system.
