Abstract
The present disclosure discloses a low-energy-consumption grading and positioning method and system for a coal mine auxiliary transportation vehicle, which belongs to the technical field of mine tunnel transportation. The method comprises the following steps: S, determining an optimal transportation route of a vehicle, and dividing the optimal transportation route into a plurality of locked intervals; S, determining an initial velocity vof the vehicle passing through each locked interval; S, constructing a discretization mileage estimation model to update a real-time position of the vehicle, and obtaining dynamic track information of the vehicle in each locked interval; S, constructing a [v0, t] prediction model, and obtaining a theoretical time tof the vehicle passing through each locked interval through the prediction model; S, comparing a actual time t and the theoretical time tof the vehicle passing through each locked interval, and selecting whether to start overtime early warning or overtime alarm; and S, repeating Sto Safter the vehicle enters the next locked interval. The low-energy-consumption grading and positioning method and system for the coal mine auxiliary transportation vehicle provided in the present disclosure realizes on-demand positioning of the underground vehicle and reduces the consumption and cost of positioning.
