In order to optimize the parameters in RVM, which has a great influence on the performance of RVM, the optimization algorithm Gravitational Search Algorithm (GSA) is introduced. Shearer Positioning System Based on SINS. The strap-down inertial navigation system (SINS) is a commonly used sensor for autonomous underground navigation, which can be used for shearer positioning under a coal mine. Finally, the experimental results show that the multi-model intelligent switching fault-tolerant positioning algorithm can effectively overcome increased positioning error of tightly-coupled model and decision tree model based on these two invalid styles. three-axis gyroscope and a three-axis accelerometer, whose axes are orthogonal. reflect the position information of the shearer. certain reference coordinate system at, navigation coordinate system. The authors declare no conflict of interest. The SINS was fixedly installed on the agricultural machinery. In recent decades Global Positioning Systems (GPS) have become a ubiquitous tool to support navigation. Double ended ranging drum shearer and method of controlling working height in mining face in use of the same Download PDF Info Publication number US4822105A.

This method of mining was developed in the late 1960's to take advantage of the then recent development of suitable hydraulic longwall supports, coupled with the productivity and low capital cost of continuous miners and shuttle cars. Meanwhile, this strategy can effectively estimate the linear velocity of the shearer’s fuselage and avoid the error caused by the system disturbance assumption. Secondly, the multi-model intelligent switching algorithm can be established based on the shearer Markoff movement state and residual threshold judgment of Kalman Filter. The coning error and sculling error of SINS with four samples algorithm were increased by 29.8% and 28.3% compared with those of three samples algorithm, respectively. However, under the complex environment of the mechanized mining face, the strong vibration of the shearer may cause large calculation error. The maximum position error with the positioning model proposed in this paper is 0.93 m in 327 s, and the positioning accuracy with multi-model intelligent switching model is much greater than that with tightly-coupled integration and the decision tree fault tolerant models. (CC BY) license (http://creativecommons.org/licenses/by/4.0/). SINS/UWB integrated system decreases quickly, due to the drift error of SINS. Kalman Filter (ATKF) for SINS/OD integrated navigation systems is proposed. The experimental results indicated that the resulted vibration error such as the coning error and sculling error by using four-sample algorithm is 29.8% and 28.3% lower than the errors by using three-sample algorithm. We conducted shearer positioning experiments with gyroscopes, accelerometers, and other inertial navigation instruments. All rights reserved.

Using as a base of SINS/UWB integrated positioning system, the signal interference and node damage of UWB often cause invalid integrated positioning system, because of the bad working environment of shearer in the coal mine. Shearer Positioning System Based on SINS, 2.1. In addition, the real-time connection and coupling relationship between the two devices is analyzed. I recently looked at Book 4 from this series and was very pleased to receive the complete set from the Aaron Shearer Foundation.I have used the old series for a long time, in particular the Classic … Compared with the traditional multiple fading factor strong tracking Kalman filter (MSTKF) method, the proposed MSTSKF algorithm integrates the advantage of strong tracking Kalman filter and sequential filter, and multiple fading factor and forgetting factor for east and north velocity measurement are designed in the algorithm, respectively, which can effectively weaken the coupling relationship between the different states and increase strong robustness against process uncertainties. The shearer cuts a slice of coal from the coalface on each pass and a face conveyor, running along the full length of the coalface, carries this away to discharge onto a belt conveyor, which carries the coal out of the mine. Consequently, positioning accuracy of SINS/UWB integrated system decreases quickly, due to the drift error of SINS. the book is filled with carefully graded original exercises and pieces. A real experiment is carried out to further validate the performance of the proposed algorithm. Buy the Book or Look Inside .
