Abstract

A communication system between a base station and a plurality of pieces of construction equipment, the communication system including a transmitter and receiver for transmitting measured operational information from the plurality of pieces of construction equipment to the base station. Each equipment piece includes an operational component that is susceptible to damage. A computer based controller is utilized for measuring a plurality of operational parameters of a respective equipment piece and communicating derived measured operational information. A calculator is used for calculating an amount of damage incurred by the component based on the communicated measured operational information concerning the respective equipment piece.

Claims

1. A communication system between a base station and a plurality of pieces of construction equipment, said communication system comprising:

transmitting means and receiving means for transmitting measured operational information from the plurality of pieces of construction equipment to the base station and wherein each equipment piece comprises an operational component that is susceptible to damage;

a control means for measuring a plurality of operational parameters of a respective equipment piece and communicating measured operational information derived therefrom over said transmitting means and receiving means to the base station; and

calculating means for calculating an amount of damage incurred by the component based on said communicated measured operational information concerning the respective equipment piece.

2. The communication system as recited in claim 1, further comprising a damage mitigation means for adapting future operation of the respective equipment piece based on the calculated amount of incurred damage.

3. The communication system as recited in claim 1, wherein said damage mitigation means is an actuator arranged for influencing operating conditions of the operational component.

4. The communication system as recited in claim 1, further comprising storage means for storing a result of the calculated amount of incurred damage.

5. The communication system as recited in claim 1, wherein said operational component is a part in a powertrain of the respective equipment piece.

6. The communication system as recited in claim 1, wherein said operational component is a gear wheel in a gear box of the respective equipment piece.

7. The communication system as recited in claim 1, wherein said transmitting means and receiving means communicate data via radio waves.

8. The communication system as recited in claim 7, wherein said radio waves are transmitted via satellite.

9. The communication system as recited in claim 1, wherein said control means is further configured for measuring a first parameter which corresponds to an operational state that generates damage in the operational component and a second parameter which corresponds to an operational condition that enhances damage imposed on the component by the first parameter.

10. The communication system as recited in claim 1, further comprising determination means for determining a total load defined by the total effect on the life of the object by the operational state and the operational condition.

11. The communication system as recited in claim 10, wherein said determination means is further adapted to calculate the total load in consideration of variations in damage resistance of the operational component.

12. The communication system as recited in claim 11, wherein the total load is calculated as a product of a function for the operational state and a function for the operational condition.

13. A system for wireless communication between a base station and a plurality of vehicles via transmitting and receiving means for checking the operational status of the vehicles, wherein each vehicle comprises an object which is susceptible to damage and means for measuring a number of operational parameters of the object, wherein the system comprises means for calculating damage done to the object based on said measured operational parameters and wherein each vehicle comprises transmission means for transmitting information regarding the measured operational parameters or calculated damage to the base station and wherein the base station comprises decision means adapted for controlling future operation of said vehicles based on the calculated damage.

14. The system as recited in claim 13, wherein the vehicles are construction machines.

15. The system as recited in claim 14, wherein said object susceptible to damage constitutes a component in a powertrain.

16. The system as recited in claim 15, wherein said object susceptible to damage constitutes a gear wheel in a gear box.

17. The system as recited in claim 13, wherein the measuring means is adapted for measuring a first parameter which corresponds to an operational state which generates said damage to the object, and at least a second parameter which corresponds to a condition for or around the object that by itself is not able to generate the damage, but which makes the damage generated by the operational state worse.

18. The system as recited in claim 17, wherein the system comprises means for determining a total load which is defined by the total effect on the life of the object by the operational state and the operational condition.

19. The system as recited in claim 18, wherein the determination means is adapted to calculate the total load in such a way that variations in the damage resistance of the object which the operational condition gives rise to are adjusted for.

20. The system as recited in claim 19, wherein the total load is expressed as a product of a function for the operational state and a function for the operational condition.

21. A communication system between a base station and at least one remotely positioned stationary or mobile machine via transmitting and receiving means for checking the operational status of the machine, with the machine comprising an object which is susceptible to damage, and wherein the system comprises a control unit, means for measuring a number of operational parameters of the object, and means for calculating damage done to the object based on said measured operational parameters.

22. The communication system as recited in claim 21, wherein the system comprises a unit arranged to take steps for the future operation of one of the machine and the object based on said calculation.

23. The communication system as recited in claim 22, wherein said unit for taking steps is a station for spare parts, maintenance or restoration.
