Simulation and experiment on the attitude monitoring of roadheader based on ultra wide band

Considering the low level of coal mine roadheader posture monitoring and positioning device automation at present, and the problem of low precision, a study of roadheader posture measurement method based on UWB positioning technology was investigated.The attitude of roadheader was measured by a synchronous moving device with the roadheader.The feasibility of the proposed method was verified by Matlab simulation software and experimental method.The research results show that the increase in the base station and the tag distance will reduce the attitude accuracy, therefore a reasonable spacing between roadheader and measuring device needs to be set.Increasing tag and tag distance will improve the attitude measurement precision, therefore a reasonable installation position of the label needs to be set.Label the Z axis measuring accuracy is low, and can affect the attitude measurement accuracy.The attitude measurement precision of roadheader can be improved through the integration of a variety of measurement techniques.
