Title:
LOW-POWER-CONSUMPTION GRADED POSITIONING METHOD AND SYSTEM FOR COAL-MINE AUXILIARY TRANSPORTATION VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/178981
Kind Code:
A1
Abstract:
The present application belongs to the technical field of transportations in mine tunnels, and relates to a low-power-consumption graded positioning method and system for a coal-mine auxiliary transportation vehicle. The method comprises: S10, determining an optimal transportation route for a vehicle, and dividing the optimal transportation route into a plurality of closed sections; S20, determining an initial speed v0 of the vehicle passing through each closed section; S30, establishing a discretized mileage estimation model, and updating, in real-time, the position of the vehicle, so as to obtain dynamic trajectory information of the vehicle within each closed section; S40, establishing a [v0, t] prediction model, and obtaining, by means of the prediction model, a theoretical time t0 of the vehicle passing through each closed section; S50, comparing the actual time t and theoretical time t0 of the vehicle passing through each closed section, and choosing whether to give an early-warning regarding expiration or raise an alarm regarding expiration; and S60, after the vehicle enters the next closed section, executing S30-S50 again The low-power-consumption graded positioning method and system for a coal mine auxiliary transportation vehicle in the present application realizes on-demand positioning of an underground vehicle, and reduces the power consumption and costs for positioning.
