A construction tower crane automatic operation system and control method based on Beidou/GPS precise positioning

Abstract

The invention relates to an automatic construction tower crane operation system and control method based on Beidou / GPS precise positioning. Risks and low efficiency which are generated due to artificial control of a traditional tower crane are avoided, and the problems of automatic conducting and accurate positioning in a construction tower crane are solved through the system. In the method, three basic technologies including a Beidou satellite positioning system and differential base station system, an equipment-assisted positioning system based on a sensor and a programmable digital motor system are applied. According to the method, an accurate position positioning function based on the Beidou, an assisted tower crane operation position positioning function, a precise material placing site position positioning function and an automatic tower crane equipment operation route planning function are provided; a client automatically sends relevant parameters to a tower crane control system through a handheld device, and the tower crane automatically operates on the basis of the parameters. The system monitors the skewness degree of a tower crane body, so that tower crane collapse is prevented; the system provides a remote site video accessing function; the system provides a remote operating mode.

Description

technical field [0001] The present invention is based on Beidou precise positioning and numerical control technology, and involves construction equipment operating on the surface of the earth. It requires precise numerical control systems such as longitude, latitude, and elevation information. The system uses the accurate positioning characteristics of China's Beidou positioning system and combines it with electronic control technology. Realize the automatic operation management of the construction tower crane. In particular, it relates to an automatic operation system and control method of a construction tower crane based on Beidou / GPS precise positioning. Background technique [0002] The purpose of the construction tower crane is to hoist the construction equipment and materials at a designated location on the construction site to another designated location. The cab of the traditional tower crane is on the top of the tower crane, and the operator controls the operation ...

AI Technical Summary

Problems solved by technology

Therefore, the positioning and operation of the tower crane depends on the coordination of long-distance artificial vision and sound methods such as the working surface, the cockpit, and high-rise buildings. Inevitably, there are low command efficiency and production liability accidents due to poor communication.

At the same time, since the cab is installed on the upper part of the tower crane, the operator works at high altitude for a long time, and the process of getting on and off the cab of the tower crane and the operation process are highly dangerous tasks
