Abstract :
According to the disadvantage of low precision and big error in previous shearer positioning system, the author proposes a new design concept: using the sensor information of shearer, scraper conveyor and hydraulic supports to define the shearer\´s position which is called "three-machine position", combining the sensor information of motion state and static state which is called "static and dynamic fusion". This paper solves the problem of three-dimensional positioning in shearer movement process and deduces the related formulas. The experimental result shows that this system can improve the positioning accuracy and stability effectively, provide guarantee for the realization of shearer memory cutting of and remote control.
