Method and system for real-time generation of hoisting scheme in on-board controller of jib crane

Abstract

The invention discloses a real-time generation method of a hoisting scheme of a jib crane in a vehicle controller and a method thereof, according to the method, an autonomous detection learning by the crane jib is employed, profile and position information of an obstacle in an operation area can be accurately acquired; source position and target position information of an hoisting object which are acquired by the crane jib are employed, according to an environment data table in the hoisting operation area, by combining the a hoisting performance chart of the crane, the hoisting scheme comprising parameters such as crane jib length, rotation direction and a lower elevation angle of each rotation angle enables real-time generation in a vehicle controller, and the generated hoisting scheme is optimized and simulated. The practical hoisting application shows that the system can accurately acquire the environment data in the operation area and can generate the hoisting scheme through optimization.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a method and system for generating a hoisting scheme in a vehicle-mounted controller of a jib crane in real time. Background technique [0002] Cranes are widely used in the construction and transportation industries, but safety accidents involving crane hoisting operations occur frequently. For example, there were 76 and 61 major safety accidents involving hoisting machinery in my country in 2012 and 2013, accounting for 33.3% and 26.87% of the total special equipment safety accidents, and the death toll accounted for 44.2% and 29.07% of the total special equipment accident deaths. . For wheeled cranes, because they have both the mobility of cars and the hoisting characteristics of cranes, they are more likely to cause safety accidents than other types of cranes. [0003] The hoisting scheme planning and simulation before the hoisting operation is an important link to...

AI Technical Summary

Problems solved by technology

The establishment of the 3D model, the search and optimization algorithm of the hoisting path are complex, and usually require the use of professional software, which is difficult to implement in the on-board controller with limited resources. It is suitable for the early stage of the hoisting process in non-real-time situations with minor changes in the environment in the hoisting operation area preparation, but not suitable for wheeled cranes that frequently change their hoisting environment
