Method and system for dynamic adjustment of hazardous area range of bridge crane

Abstract

The present disclosure provides a dynamic adjustment method and system of a dangerous area range of a bridge crane. The method includes: obtaining the dangerous area range of the bridge crane at different speeds in the case of small swing by using an MFC algorithm control scheme based on angle constraints; repeating the operation for several times to obtain a group of corresponding data of the area of the dangerous area range at different speeds, and showing the same in a coordinate chart; constructing an analytic function via the obtained data set by using a least square method polynomial curve fitting method, so as to make values at original discrete points as close as possible to given values; and based on the analytic function, combined with a real-time operating speed of the bridge crane during normal operation, calculating the area of the dangerous area range in real time. The present disclosure enables the bridge crane to obtain the area of the dangerous area range in real time during the normal operation of the crane, and the bridge crane can plan a more efficient operating path through the area of the dangerous area range to realize optimal path obstacle avoidance at last.

Description

technical field [0001] The disclosure belongs to the technical field of dynamic adjustment of the range of dangerous areas of bridge cranes, and relates to a method and system for dynamically adjusting the range of dangerous areas of bridge cranes based on MPC (Model Predictive Control). Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] With the rapid development of industry, bridge cranes play an increasingly important role in the modern production process, so the requirements for the dynamic adjustment mechanism of the dangerous area range in the control process of bridge cranes are also getting higher and higher. At present, most factories use the staff to operate the bridge crane to carry objects. Sometimes the objects carried by the bridge crane may collide with other important equipment in the factory due to the lack of operation abil...

AI Technical Summary

Problems solved by technology

At present, most factories use the staff to operate the bridge crane to carry objects. Sometimes the objects carried by the bridge crane may collide with other important equipment in the factory due to the lack of operation ability of the staff.

In the whole process, the labor intensity of workers is high, the efficiency is low, and the safety factor is not high

Especially in a working environment with many obstacles and a complicated environment, it is difficult to find a low-cost and experienced technician to reduce the probability of overhead crane collision
