A method for avoiding conflicts between cranes and unmanned multi-day workshops

Abstract

The invention relates to a method for avoiding multi-vehicle conflicts in unmanned crane driving, and belongs to the technical field of metallurgical automatic control. The technical solution of the present invention is: through communicating with the crane unmanned system, receiving the input of the crane unmanned system, and at the same time sending operation instructions to the crane unmanned system; The current running direction determines the final execution plan (8). The present invention can issue reasonable, accurate and unique operation instructions, shorten the stop and wait time of the avoidance crane, and reduce the probability of conflicts and emergency stops between the crane and the crane, thereby greatly improving the operation efficiency of the crane; according to the sky Different avoidance strategies are adopted in the running or stationary state of the car. By using pre-calculation avoidance, process control avoidance and damage avoidance strategies to better protect equipment, the efficiency is guaranteed and the conflict avoidance is more reasonable, which adapts to the future needs of the development of the crane driverless system. , sustainable smooth and efficient operation of unmanned cranes with increasing complexity.

Description

technical field [0001] The invention relates to a method for avoiding conflicts in multi-day workshops with unmanned driving of cranes, which is used to solve the problem of conflicts in multi-day workshops caused by unmanned driving technology in metallurgical warehouses. Pre-calculation and process are performed by computers The control and destruction method reasonably avoids conflicts and ensures the smooth operation of the crane, belonging to the technical field of metallurgical automatic control. Background technique [0002] With the development of smart factories in the metallurgical industry, the unmanned driving system of warehouse cranes has received widespread attention. The characteristics of crane operation are more prominent in the unmanned driving system: there are public areas in the multi-day workshop to complete the cooperation between the crane and the crane, and the operation in the overlapping area will cause the conflict between the crane and the crane...

AI Technical Summary

Problems solved by technology

If two or more cranes operate the same type of work at the same time, it will lead to conflict between the cranes; the tight operation will lead to a short waiting time for the cranes, and it is impossible for one crane to complete another operation, so many cranes will respond at the same time It will lead to conflicts between the crane and the workshop, that is to say, the efficiency cannot be lost while avoiding the conflict; the unmanned anti-swing technology of the crane requires that the crane can only stop at the destination after it starts, and the abnormal stop in the middle process greatly reduces the operating efficiency of the crane. This requires that conflict avoidance must be controlled when the crane changes from stationary to motion, in order to achieve reasonable conflict avoidance

The rationality of conflict avoidance directly determines the performance of the crane unmanned driving system, unreasonable avoidance strategies, low operating efficiency and poor user experience
