AI Technical Summary

Technical Problem

Existing tailings mining control methods lack parameter self-correction and multi-machine collaborative avoidance mechanisms under dynamic operating conditions, resulting in poor system stability, high operation interruption rate, and difficulty in guaranteeing overall efficiency.

Method used

By collecting physical property data of tailings, marking high-variable areas, constructing input vectors, generating control commands using proportional-integral-derivative controllers, and providing feedback correction when deviations exceed limits, the system combines vibration spectrum and load torque criteria to trigger working condition reconstruction, updates the interpolation function, generates a local optimal parameter set, reallocates the working area based on working efficiency and generates conflict-free paths, and trains parameter mapping strategies for gray-scale release.

Benefits of technology

It effectively suppresses execution deviations, avoids interference between multiple machine trajectories, ensures stable and coordinated operation of the system under complex working conditions, and improves the continuity of operations and the overall control robustness.

Abstract

This invention belongs to the field of tailings mining technology, specifically relating to a tailings mining control method and system. By constructing a multi-dimensional over-limit criterion based on deviation, vibration spectrum, and load torque, a working condition reconfiguration mechanism is actively triggered. During the freeze period, a response matrix is ​​constructed using steady-state data, and parameter corrections are solved to achieve online updates of interpolation function nodes and slopes. Furthermore, based on the updated mapping relationship, a locally optimal parameter set is generated for multiple devices, and interference risk is dynamically calculated according to the predicted trajectory. If conflicts exist, the area is redistributed according to operational efficiency, and conflict-free paths are generated. This effectively suppresses execution deviations caused by parameter mismatch, avoids multi-machine trajectory interference, ensures stable and coordinated operation of the system under complex disturbance conditions, and significantly improves operational continuity and overall control robustness.
