Tower crane control method and system

Abstract

The invention provides a tower crane control method and system. The tower crane control method includes the steps that data information of a base station, a tower crane and a destination are obtainedby GPS satellite transmitting signals received by the base station installed on a measuring area and mobile receiving stations arranged on the tower crane and the transportation destination correspondingly; phase difference processing is carried out according to the data information of the base station and the data information of the tower crane and the transportation destination, and longitude and latitude coordinates of the tower crane and the transportation destination in a geocentric coordinate system WGS-84 are obtained; and the longitude and latitude coordinates of the tower crane and the transportation destination in the geocentric coordinate system WGS-84are converted into spatial rectangular coordinates to obtain a starting three-dimensional coordinate of the tower crane and a final three-dimensional coordinate of the transportation destination, and after calculating operation parameters of the tower crane, a control instruction is sent to a control circuit of the tower craneto remotely control operation of the tower crane. According to the tower crane control method and system, through positioning and coordinate converting of the tower crane and the transportation destination of goods, operation of the tower crane is remotely controlled according to the coordinates, no need to manually drive the tower crane, the risk of tower crane operation is reduced, and the positioning accuracy is high.

Description

technical field [0001] The present invention mainly relates to the technical field of tower crane control, in particular to a tower crane control method and system. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites, also known as tower crane. It is used to lift steel bars, wooden corrugated, Concrete, steel pipe and other raw materials for construction, tower crane is an indispensable equipment on the construction site. [0003] In the prior art, the operator of the tower crane has to follow the simple stairs up to 100 meters inside the tower crane to reach the narrow driver's room on the top of the tower crane to operate the tower crane. Due to the trouble of going up and down the tower crane, the operator has to stay in the driver's cab under poor conditions for a long time. When the operator has an accident, the rescue will become very complicated. At the same time, the operator cannot clearly see the material tra...

Problems solved by technology

Due to the trouble of going up and down the tower crane, the operator has to stay in the driver's cab under poor conditions for a long time. When the operator has an accident, the rescue will become very complicated. At the same time, the operator cannot clearly see the material transfer situation in the driver's cab in most cases. It can be directed by the commander. The whole operation process re
