CONTROLLING A CONVEYOR IN A MINING SYSTEM

摘要

Systems and methods for controlling a conveyor in a mining system. The conveyor includes a chain, a first sprocket, a second sprocket, a drive mechanism, a first sensor, a second sensor, and a controller. The method includes receiving a first signal associated with a characteristic of at least one of a first sprocket or a second sprocket, determining a value for the characteristic of the at least one of the first sprocket or the second sprocket based on the first signal, receiving a second signal associated with a characteristic of a chain, and determining a value for the characteristic of the chain based on the second signal. The method further includes comparing the value for the characteristic of the at least one of the first sprocket or the second sprocket and the value for the characteristic of the chain and determining the amount of slack in the chain based on the comparison.

1. A conveyor for a mining system, the conveyor comprising:
a first sprocket and a second sprocket; a chain associated with the first sprocket and the second sprocket; a drive mechanism coupled to the first sprocket or the second sprocket, the drive mechanism operable to drive the first sprocket or the second sprocket; a first sensor operable to generate a first signal related to a characteristic of the first sprocket or the second sprocket; a second sensor operable to generate a second signal related to a characteristic of the chain; and a controller operable toreceive the first signal from the first sensor,determine a value for the characteristic of the first sprocket or the second sprocket based on the first signal,receive the second signal from the second sensor,determine a value for the characteristic of the chain based on the second signal,compare the value for the characteristic of the first sprocket or the second sprocket and the value for the characteristic of the chain, anddetermine an amount of slack in the chain based on the comparison.
