Embodiment Construction

[0058] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the embodiments of the present application and the features in the embodiments can be combined arbitrarily with each other.

[0059] In related technologies, the tower cranes used in construction sites and bridge erection are basically operated by humans, which not only has low control accuracy, but also poses great risks to the operators themselves.

[0060] In view of this, this application combines high-precision satellite positioning and direction finding with the tower crane control system, which can effectively improve the control efficiency of the tower crane, greatly reduce the number of tower crane operators and the workload of the ope...

Abstract

The embodiment of the application discloses an automatic control method for a tower crane. The automatic control method comprises the following steps of obtaining position information and real-time GNSS direction finding information of a lifting hook position point A, a material loading position point B and a material loading position point C relative to a reference station position point O; according to the obtained direction finding information and position Information, calculating azimuth included angle information; calculating an elevation difference and a level difference; and adjusting arotation azimuth angle of a cross rod of the tower crane by using the calculated azimuth included angle information, and adjusting the lifting height of the lifting hook position point A and the horizontal movement distance of a lifting hook on the cross rod of the tower crane by using the calculated height difference and level difference.

Description

technical field [0001] The embodiment of the present application relates to the field of information processing, in particular to an automatic control method for a tower crane. Background technique [0002] With the continuous improvement of the development of Global Navigation Satellite System (GNSS), the application of GNSS in various fields has shown excellent prospects, and has been widely used in navigation, surveying and mapping, precision agriculture, unmanned driving, UAVs and many other fields. In particular, China's Beidou system has completed the construction of the third generation of Beidou, and about 20 satellites can be observed in the Asia-Pacific region, further expanding the application scenarios of GNSS positioning. Multi-system joint positioning (BDS, GPS, GALILEO, GLONASS, QZSS, etc.) can observe more than 50 satellites at the same time, which enables users to realize RTK (Real-Time Kinematic, real-time dynamic) in complex occlusion environments Fixed ...
