Controlling a conveyor in a mining system

摘要

Controlling a distance between a first sprocket and a second sprocket in a conveyor. The control includes receiving a first signal from a first sensor related to an angular position of the first sprocket, determining a value for an angular position of the first sprocket based on the first signal, receiving a second signal from a second sensor related to an angular position of the second sprocket, determining a value for an angular position of the second sprocket based on the second signal, determining a relative difference in phase between the angular position of the first sprocket and the angular position of the second sprocket, and determining an amount of excess chain in the conveyor based on the relative difference in phase between the angular position of the first sprocket and the angular position of the second sprocket.

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 an angular position of the first sprocket; a second sensor operable to generate a second signal related to an angular position of the second sprocket; and a controller including a processor and a memory, the controller operable to
receive the first signal from the first sensor,determine a value for the angular position of the first sprocket based on the first signal,receive the second signal from the second sensor,determine a value for the angular position of the second sprocket based on the second signal,determine a relative difference in phase between the angular position of the first sprocket and the angular position of the second sprocket,determine an amount of excess chain in the conveyor based on the relative difference in phase between the angular position of the first sprocket and the angular position of the second sprocket, andgenerate a control signal for controlling a distance between the first sprocket and the second sprocket based on the amount of excess chain.
