Abstract EN
In a fully mechanized coal-mining face, the positioning and attitude of the shearer and scraper conveyor are inaccurate.
To overcome this problem, a joint positioning and attitude solving method that considers the effect of an uneven floor is proposed.
In addition, the real-time connection and coupling relationship between the two devices is analyzed.
Two types of sensors, namely, the tilt sensor and strapdown inertial navigation system (SINS), are used to measure the shearer body pitch angle and the scraper conveyor shape, respectively.
To improve the accuracy, two pieces of information are fused using the adaptive information fusion algorithm.
It is observed that, using a marking strategy, the shearer body pitch angle can be reversely mapped to the real-time shape of the scraper conveyor.
Then, a virtual-reality (VR) software that can visually simulate this entire operation process under different conditions is developed.
Finally, experiments are conducted on a prototype experimental platform.
The positioning error is found to be less than 0.38 times the middle trough length; moreover, no accumulated error is detected.
This method can monitor the operation of the shearer and scraper conveyor in a highly dynamic and precise manner and provide strong technical support for safe and efficient operation of a fully mechanized coal-mining face.
