Tower crane lifting system based on wireless positioning

Abstract

The invention provides a tower crane lifting system based on wireless positioning. The tower crane lifting system comprises a positioning card, a base station, a terminal and lifting equipment, wherein the positioning card is arranged on the lifting equipment and a lifting position, and the positioning card, the base station and the lifting equipment wirelessly communicate with the terminal respectively; the positioning card is used for recording first sending time for sending a wireless signal to the base station by the positioning card and first receiving time for receiving the wireless signal from the base station; the base station is used for receiving the first sending time and the first receiving time which are transmitted by the positioning card, and calculating the distance between the positioning card and the base station in combination with second receiving time for receiving the wireless signal from the base station and second sending time for sending the wireless signal to the base station; the terminal is used for controlling the lifting equipment according to the distance between the positioning card and the base station and position information of the positioning card and the base station. According to the tower crane lifting system, the relationship between the lifting position and a lifting hook of the lifting equipment in three-dimensional space can be accurately positioned, the cost is reduced, and the safety is improved.

Description

technical field

[0001] The invention relates to a tower crane hoisting system, in particular to a tower crane hoisting system based on wireless positioning. Background technique

[0002] Because the tower crane equipment is very large, it is more and more difficult to hoist the equipment to the designated position, mainly because the operator operates the machine at high altitude, but the hoisted items are far away from the operator, and the operator relies entirely on his eyes and experience It is difficult to hoist the equipment to the designated position; the traditional solution is: one person operates the hoisting equipment, and the other informs the operator of the relationship between the hoisted items and the designated position through a walkie-talkie, and directs the hoisting personnel to hoist the items to the designated position.

[0003] This solution in the prior art is slow in hoisting speed, low in efficiency, and cumbersome to operate; and to solve this prob...
