Electric shovel positioning method based on density clustering

Abstract

The invention belongs to the technical field of strip mine production, and particularly relates to a density clustering-based electric shovel positioning method, which comprises the following steps of: calculating a vehicle-shovel corresponding relation by utilizing a scheduling operation plan of each shift and GPS (Global Positioning System) dynamic positioning data according to operation time and tracks of a shovel where a transport vehicle is located, a rock crushing turnover point and an ore crushing turnover point; and the preliminary positioning information of the electric shovel is obtained by using a DBSCAND algorithm. Performing trajectory prediction on the failure positions of the electric shovel and the transport vehicle by using a GPR algorithm, analyzing data of a signal vanishing point of the electric shovel and a signal vanishing point of the transport vehicle, performing least square method curve fitting on a plurality of predicted values, and performing mapping on each intersection point of the predicted trajectory on a connecting line of the failure positions of the electric shovel and the transport vehicle; and taking the point with the maximum mapping density as the accurate operation position of the electric shovel. According to the method, on the basis of existing equipment, a proper algorithm is used for calculation, the accurate position of the electric shovel can be obtained without re-investment of the equipment, reference data is provided for production scheduling, and lean production of mines is further achieved.

Description

technical field [0001] The invention belongs to the technical field of open-pit mine production, in particular to an electric shovel positioning method based on density clustering. Background technique [0002] An open-pit mine is a large-scale production system with mining as the center and transportation as the link. The completion of the production indicators and tasks of the open pit mine, as well as the organization and implementation of the production process are all completed through the real-time scheduling of the mining and transportation equipment. Therefore, as an important mining and transportation equipment, the accurate positioning of the electric shovel is crucial. [0003] In the actual production process, the position of the electric shovel will have physical shielding and electromagnetic interference. Even if the communication jump technology is used for data transmission, there are still some electric shovels in absolute blind spots, and the specific locat...

Problems solved by technology

[0003] In the actual production process, there will be physical occlusion and electromagnetic interference at the location of the electric shovel. Even if the communication jump technology is used for data transmission, some electric shovels are still in absolute blind spots, and the specific location of the electric shovel cannot be obtained; while transportation The car is a mobile device, and it can transmit GPS positioning signals when it runs near a base station with a good network, but there are also communication blind spots
