Problems solved by technology

[0003] This solution in the prior art is slow in hoisting speed, low in efficiency, and cumbersome to operate; and to solve this problem, some people think of using video technology to install the camera on the hoisting device, but this still has the following problems: 1. The installation position of the camera, the cable installed on the hoisting equipment, will be blo

Embodiment 1

[0025] This example provides a tower crane hoisting system based on wireless positioning, including: a positioning card, a base station, a terminal, and a hoisting device; Realize wireless communication with the terminal; the positioning card is used to record the first sending time of the positioning card sending the wireless signal to the base station and the first receiving time of receiving the wireless signal of the base station, and the first sending time and the first receiving time of the wireless signal through the wireless signal The time is transmitted to the base station; the base station receives the first sending time and the first receiving time transmitted by the positioning card, and calculates the positioning card by combining the second receiving time and the second sending time of the base station itself for receiving and sending wireless signals to the positioning card The distance from the base station; the terminal controls the hoisting equipment accordin...

Embodiment 2

[0031] likefigure 1 As shown, on the basis of Embodiment 1, the base station described in this example is installed on the iron frame platform under the hoisting equipment control room, and the iron frame platform is used to raise the tower crane; the number of the base stations is at least three, The number of base stations described in this example is three, one of which is installed near the slewing support of the hoisting equipment, and the other base stations are respectively installed on two corners of the top floor of the building to achieve three-dimensional positioning; the positioning card includes the first positioning card and a second positioning card, the first positioning card is installed on the hook of the hoisting equipment for real-time transmission of positioning data; The location of the positioning card in 3D positioning.

[0032] The working process of this example is as follows: First, to locate the hoisting equipment, the base station for wireless posi...

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...
