Abstract

Disclosed are a tower crane video monitoring control apparatus, method and system, and a tower crane. The apparatus comprises: a receiving device for receiving the height and range of a lifting hook of the tower crane; and a control device for calculating the horizontal distance and vertical distance between the lifting hook of the tower crane and a camera according to the height and range of the lifting hook of the tower crane; and executing at least one of the following: calculating a pitch angle of the camera when the camera aims at the lifting hook according to the horizontal distance and vertical distance, and adjusting a rotating mechanism of the camera according to the angle, so that the camera aims at the lifting hook; and calculating the distance between the camera and the lifting hook according to the horizontal distance and vertical distance, calculating a field angle of the camera according to the distance and a set value of an observation radius of an object hanging area, and controlling the camera to conduct magnification adjustment according to the field angle.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a tower crane video surveillance control device, method, system and tower crane. Background technique [0002] Although the general tower crane safety monitoring system can maximize the protection of tower crane operation in terms of overrun protection, tower crane operators cannot fully control the situation on the construction site due to limited vision when working at heights, which affects the construction progress and Safety. [0003] The existing tower crane video monitoring system can only provide construction images of a certain construction site. However, during the operation of the tower crane, the hook is constantly moving up and down. Operators need to always pay attention to the construction images near the hook to help It is used to make operational judgments to avoid safety accidents. Therefore, the development of a tower crane video safety monitoring system ...
