no. 1 example

[0031] Such as figure 1 As shown, the first embodiment of the crane receiving system of the present invention includes:

[0032] Step S10: Obtain real-time status information of the crane and real-time information of obstacles around the crane;

[0033] Among them, the real-time status information of the crane may include: first real-time status information for determining the position of the main / auxiliary hook, second real-time status information for determining the load status of the main / auxiliary hook, and second real-time status information for determining the status of the boom. 3. Real-time status information;

[0034] Step S20: According to the real-time status information of the crane and the real-time information of the obstacle, it is judged whether the preset vehicle receiving condition is met;

[0035] Step S30: When it is judged that the preset car receiving condition is met, the car receiving action is controlled and executed according to the real-time status...

Abstract

The invention provides an off-running method for a crane and a system. The off-running method for the crane includes acquiring real-time state information of the crane and real-time information of obstacles around the crane; judging whether preset off-running conditions are met or not according to the real-time state information of the crane and the real-time information of the obstacles; and controlling and actuating an off-running action according to the real-time state information of the crane and the real-time information of the obstacles. An intelligent off-running means is provided, manual intervention is omitted, automatic off-running and a drivable state of the crane can be realized without manual operation, labor intensity is reduced, work efficiency is improved, and cost is lowered.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a method and system for receiving a crane. Background technique [0002] With the advancement of science and technology and the demand for large-scale modern construction projects, cranes, as important construction machinery, are increasingly developing in the direction of high efficiency, automation, and intelligence. At the same time, users have higher and higher requirements for their work performance, operating comfort, and automation. Therefore, the pros and cons of products in these aspects have become the main factors that determine their market competitiveness. [0003] However, there is still a lack of an intelligent car-receiving method and system that can automatically perform the car-receiving action, which needs to be solved urgently. Contents of the invention [0004] In order to overcome the above-mentioned defects and deficiencies of the prior art, the fir...
