Abstract

The invention discloses a tower crane monitoring and early warning method and system, and a tower crane. The method comprises the following steps of: respectively obtaining images of obstacles, acquired by first imaging equipment and second imaging equipment, wherein both the first imaging equipment and the second imaging equipment are positioned on a tower arm of the tower crane; determining the distances between the obstacles and the tower arm of the tower crane according to the images and the position relation information between the first imaging equipment and the second imaging equipment; and initiating an alarm under the situation that the distances are smaller than a preset threshold value. According to the tower crane monitoring and early warning method, the system and the tower crane, the images of the obstacles are acquired by the two imaging equipment to determine the distances between the obstacles and the tower arm of the tower crane so as to monitor whether the tower arm and a lifting hook are collided with the obstacles. As the tower crane is monitored from the obstacles, the collision monitoring level of the tower crane is improved, and the occurrence of tower crane collision accidents is reduced, so that the tower crane safely and efficiently runs.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a tower crane monitoring and early warning method, system and tower crane. Background technique [0002] The tower crane is the crane with the largest working space in the construction industry. It has a high lifting height and a large working range. During the construction of large-scale projects, several or even dozens of heavy-duty tower cranes are generally used for group tower operations. Due to the limitation of the construction site, the installation of tower cranes is intensive, and sometimes one tower crane may cross-operate with several surrounding tower cranes. Adjacent tower cranes cannot guarantee a large height difference. Therefore, during the construction process, various collisions between tower cranes are likely to occur, causing major safety accidents. [0003] At present, the tower crane anti-collision method in the prior art adopts electronic control, and is compos...
