Tire conditioning optimization for a collection of mining vehicles
A system and method includes accessing a road network database to identify a tire cost for a plurality of edges in a mining road network, identifying least-cost paths between each of a plurality of nodes on the mining road network using the tire cost for each of the plurality of edges, the nodes including a loading area and a dumping area for a plurality of haul trucks, accessing a distributed objects database to identify constraints for the nodes on the mining road network, determining a production plan using the constraints for the nodes on the mining road network, determining a task assignment for each of the plurality of haul trucks using the production plan as guide, and transmitting the task assignment for each of the plurality of haul trucks.
1. A system, comprising:
a vehicle having a plurality of tires including at least one a tire pressure sensor configured to measure the pressure of a tire of the vehicle;
a communication network in electronic communication with the tire pressure sensor; and
a processor configured to execute instructions to perform the steps of:
receiving, using the communication network, an indication of a tire pressure of a tire of a vehicle from the tire pressure sensor,
determining a task assignment based upon the indication of the tire pressure of the tire of the vehicle, and
transmitting, using the communication network, the task assignment to a navigation aid of the vehicle for output to an operator of the vehicle
wherein the processor is configured to determine the task assignment by:
comparing the indication of the tire pressure to a first pressure threshold and a second pressure threshold, the second pressure threshold being less than the first pressure threshold; and
when the indication of the tire pressure is less than the first pressure threshold and greater than the second pressure threshold:
determining whether the vehicle has a current task assignment; and
when the vehicle does not have a current task assignment, determining that the task assignment is an assignment configured to cause the vehicle to navigate to a tire shop; and
wherein the vehicle is an autonomous vehicle and transmitting the task assignment to the navigation aid for output to the operator of the vehicle includes causing the operator of the autonomous vehicle to undertake a task described in the task assignment.
2. The system of claim 1 , wherein the processor is configured to determine the task assignment by:
comparing the indication of the tire pressure to the first pressure threshold and the second pressure threshold; and
when the indication of the tire pressure is less than the first pressure threshold and less than the second pressure threshold:
determining whether the vehicle is empty; and
when the vehicle is empty, determining that the task assignment is an assignment configured to cause the vehicle to navigate to a tire shop.
3. The system of claim 2 , wherein the processor is configured to determine the task assignment by:
comparing the indication of the tire pressure to a third pressure threshold greater than the first pressure threshold and the second pressure threshold; and
when the indication of the tire pressure is greater than the third pressure threshold:
identifying a plurality of candidate tasks, each candidate task being a short haul task assignment; and
determining that the task assignment is an assignment selected from the plurality of candidate tasks.
4. The system of claim 1 , wherein the processor is configured to perform the steps of
receiving, using the communication network, an indication of a tire temperature of the tire of the vehicle from a temperature sensor; and
determining the task assignment based upon the indication of the tire pressure of the tire of the vehicle and the indication of the tire temperature.
5. The system of claim 4 , wherein the processor is configured to determine the task assignment by:
comparing the indication of the tire temperature to a first temperature threshold; and
when the indication of the tire temperature is greater than the first temperature threshold:
identifying a plurality of candidate tasks, each candidate task being a short haul task assignment; and
determining that the task assignment is an assignment selected from the plurality of candidate tasks.
6. The system of claim 1 , wherein the navigation aid includes a display screen configured to display at least a portion of the task assignment.
