Accurate positioning system and method for mining electric shovel

Abstract

The invention provides an accurate positioning system and method for a mining electric shovel. The system and method are characterized in that: the system comprises an electric shovel accurate positioning moving track measuring terminal, a data analysis and management system and a user management terminal; the electric shovel accurate positioning moving track measuring terminal gets access to enterprise intranet through a WIFI wireless workstation, and is connected to the data analysis and management system and the user management terminal; through data acquisition of an inertial navigation positioning module and a Beidou GPS positioning module which are arranged on a forklift and combined computing, and through a deep learning computing method, swing of electric shovel loading is eliminated, an actual moving track is researched, a large amount of collected real-time data is continuously trained, the moving track is calculated and described, real-time accurate positioning of the electric shovel is achieved, and the operation direction and the moving distance are measured according to the shift; and the obtained real-time accurate data is transmitted to a background production management center for storage in real time, so that a reliable basis is provided for electric shovel operation assessment.

Description

Technical field [0001] The invention relates to a combined technology of positioning using inertial navigation and Beidou satellites, particularly a method for precise positioning and running track measurement of an open-pit mining electric shovel. Background technique [0002] The inertial navigation system is a navigation attitude calculation system composed of inertial sensors, accelerometers, gyroscopes, and magnetic sensors as basic measurement components. It integrates computer, control, mechanics, mathematics, optics, and electromechanical disciplines to integrate various disciplines. Linked together, constitute a modern technology with high-tech content. The inertial navigation system is based on the theoretical basis of the principle of inertia, not only does not rely on any information from the outside world, but also does not radiate energy to the outside world, no matter what kind of propagation medium space, and regardless of the change of climatic conditions, it onl...

AI Technical Summary

Problems solved by technology

The position of the electric shovel carries the explosive material information. In the past, the electric shovel used GPS satellite positioning technology, and the general error was about 5-15 meters. However, the actual working distance of each shift in actual production and mining is generally about 20 meters. Usually, the electric shovel rotates left and right for loading. Car production requires forward and backward excavation of materials. The positioning points are like a mess. The working time of each shift is about 12 hours. Th
