A method for precise positioning of steel coil warehouse location for outdoor driving hoisting

Abstract

The invention relates to a method for accurately positioning a hoisting steel coil storage location of outdoor driving. Outdoor driving hoisting steel coil storage location positioning comprises a large vehicle positioning system, a small vehicle positioning system and a network communication and data collection and storage location information conversion system based on the large vehicle positioning system and the small vehicle positioning system. The large vehicle positioning system adopts a satellite navigation technology (GNSS) and a data difference technology (RTK), and comprises a base station, a large vehicle mobile station, a wireless communication module and a control and data transmission module, wherein the wireless communication module and the control and data transmission module are located between the base station and the large vehicle mobile station. The small vehicle positioning system comprises a graduation scale cable system, a vernier pointer module and a scale generation and analysis and conversion transmission module; and the storage location information system is used for collecting large and small vehicle positioning data and converting the set steel coil storage location into a specific storage location to be displayed in the computer terminal timely, and therefore accurate positioning of the hoisting steel coil storage location is achieved.

Description

technical field [0001] The invention relates to a positioning method, in particular to a method for precise positioning of storage locations of steel coils hoisted by outdoor driving. Background technique [0002] The Meishan Iron and Steel Transportation Terminal is a large-scale storage water transportation terminal of the iron and steel company, which is mainly responsible for the export of hot-rolled steel coils and plates produced by the company. The Meishan Iron and Steel Transport Terminal has 4 outdoor storage yards, which are divided into two areas. Each area (cart track) has two outdoor 16T+16T cranes. The cranes were built in 1994 and have been in use for more than 20 years. When the outdoor crane is engaged in warehousing operations, after the steel coil is hoisted by the crane and falls to the ground, the storage location information of the steel coil is manually input into the management system. Manual confirmation and input are labor-intensive and error-prone...

AI Technical Summary

Problems solved by technology

Manual confirmation and input are labor-intensive and error-prone, resulting in inaccurate storage location information, and it is even more difficult to find steel coils when they leave the warehouse

When referring to the existing driving positioning technology, outdoor driving mainly has the following three problems: first, using pure satellite navigation technology (such as GPS), the positioning data error is relatively large (several meters or even tens of meters); second, according to Due to the structural characteristics of the outdoor vehicle, satellite positioning is not suitable for the direction of the trolley, and the upper beam of the trolley blocks the signal reception of the satellite when the trolley passes by; A scale is installed at the location, and the travel of the cart is nearly 200M. The induction coil of the scale is too long, and the positioning accuracy cannot be guaranteed reliably. Fourth, the format of the positioning data is different. Two positioning methods are used, and the data collection and transmission need to be reliable. What is more critical is the need to process the data and convert it into the originally used location information
