Document Type and Number:
WIPO Patent Application WO/2022/095202
Kind Code:
A1
Abstract:
Disclosed is a fiber grating intelligent coal-rock identification device for a shearer drum. The fiber grating intelligent coal-rock identification device comprises the shearer drum; a fiber grating acceleration sensor is fixedly provided on the shearer drum, the fiber grating acceleration sensor is electrically connected to a fiber grating demodulator, the fiber grating demodulator is electrically connected to a computer, the computer is electrically connected to a signal receiver, and the signal receiver is connected to an oil pump motor for controlling the drum to move. According to the present invention, vibration signals can be effectively transmitted to a computer data processing system in time, and a curve graph is generated; real-time monitoring is achieved, the precision is high, interference of the severe environment of a coal face is avoided, stable real-time data is provided for a shearer lifting control system, deployment and maintenance are easy, and cost is low.
