Abstract

A method for monitoring the tires of vehicles transporting excavations in mines, using tire handling equipment, the tires being equipped with radio frequency identification tags and physical parameter sensors, uses a database comprising the identifiers of the vehicles, the identifiers of the tires, the identifiers of the sensors and of the positions of the tires on the axles.

First claim

The invention claimed is:

1. A method (P) for monitoring the tires of transport vehicles in mines, using tire handling equipment (TH), the tires being equipped with radio frequency identification tags and physical parameter sensors, the method (P) using a database (B) containing identifiers of the vehicles, identifiers of the tires, identifiers of the sensors and of the positions of the tires on the axles, and the method (P) including the following steps:
receiving, via the tire handling equipment (TH), an instruction containing an identity of a transport vehicle and a position of a tire to be replaced on the transport vehicle;
identifying, via the tire handling equipment (TH), the transport vehicle by means of a video acquisition and processing system, the vehicle being equipped with a detectable visual identifier, wherein the video acquisition and processing system comprises at least a wide angle camera for identifying the transport vehicle;
activating, via the tire handling equipment (TH), detection of the tire to be replaced on the vehicle by radio frequency means;
activating, via the tire handling equipment (TH), detection of the axle by means of the video acquisition and processing system, wherein the video acquisition and processing system further comprises a high resolution camera for identifying the axle of the tire to be replaced;
activating, via the tire handling equipment (TH), detection of the position of the tire on the vehicle axle by means of the video acquisition and processing system, wherein the axle position is an inner position or an outer position of a twin tire mount;
replacing, via the tire handling equipment (TH), the tire to be replaced with a replacement tire; and
updating the database (B) with the identifiers of the vehicle and of the replacement tire and a position of the replacement tire on the axle.

2. The method according to claim 1 , wherein the position of the tire on the vehicle axle is detected by calculating a distance between the high resolution camera and a vehicle hub by calculation and image processing means.

3. The method (P) according to claim 1 , further comprising a step in which the tire handling equipment (TH) activates detection of a storage area for used tires by means of the video acquisition and processing system.

4. The method (P) according to claim 3 , further comprising a step in which the tire handling equipment (TH) places the worn tire in the used tire storage area.

5. The method (P) according to claim 4 , further comprising a step in which the tire handling equipment (TH) activates detection of a replacement tire storage area by means of the video acquisition and processing system.
