An Immune Algorithm-Based Optimization Method for GPS Induced Path of Large Cable Crane

Abstract

The invention discloses an immune algorithm based GPS induction path optimization method for a large cable machine. The method comprises the steps of determining a workable range of the cable machine, selecting initial paths of two cable machines in the workable range, encoding initial path information into an initial population, setting a maximum iterative frequency, performing affinity evaluation on the initial population, and screening out high-quality antibodies and low-quality antibodies; performing cloning operation on the high-quality antibodies and the low-quality antibodies to obtain a cloned population, and performing immunization and mutation operations on the rest of antibodies except the high-quality antibodies and the low-quality antibodies to obtain an immunized population; and performing concentration inhibition to obtain a new population, and outputting a result or returning to the evaluation step. According to the method, the safety, efficiency and operability of cable machine operation are comprehensively considered, so that the efficiency is ensured on the premise of enabling the cable machine to run safely; and the influence between the cable machines is considered and a highly optimized induction path is given, so that the risk of collision between the cable machines is effectively eliminated and the construction efficiency is ensured.

Description

technical field [0001] The invention relates to the field of cable machine operation path optimization, in particular to an immune algorithm-based GPS induced path optimization method for large cable machines. Background technique [0002] Large-scale cable cranes are running on the construction site, and various construction equipment are put into them, which are arranged in a three-dimensional staggered manner, especially the working range of multiple translational cable cranes and other equipment often overlaps. These large-scale cable crane construction equipment are arranged in a three-dimensional and staggered manner. The work site is located in limited mountains and valleys, forming a cross-overlapping and mutually influencing working environment, which has buried various hidden dangers for safe construction. The weight of the cable crane itself and the weight of the lifting object are large. Once it collides with other large equipment or buildings, it is easy to caus...

Problems solved by technology

Obviously, the existing manual command and signal early warning methods are not only difficult to effectively control the collision risk in this construction mode, but also easily cause delays due to low efficiency

Therefore, in view of the simultaneous construction of multiple cable cranes, which cannot take into account safety, efficiency and operability, it is necessary to study a cable crane path optimization method that adapts to different working conditions and various natural environment constructions to ensure the safety of the cable cranes.
