Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] Such as figure 1 As shown, a highly reliable bucket wheel machine stroke positioning method of the present invention installs two sets of positioning systems (first positioning device and second positioning device) on the bucket wheel machine, and its steps are:

[0042] S1: Obtain two sets of measurement data DL data and DN data of the first positioning device and the second positioning device;

[0043] S2: Calculate the distance d1, d2 from the first positioning device and the second positioning device to the reference point P;

[0044] S3: Perform Kalman filter processing on the two sets of data to obtain the estimated optimal distance;

[0045] S4: Calculate the current coordinate position of the bucket wheel cart in combination with the preset reference point coordinates.

[0046] In the above step S1, the coordinate va...

Abstract

The invention discloses a high-reliability stroke positioning method of a bucket wheel machine. Two positioning systems are mounted on the bucket wheel machine. The high-reliability stroke positioningmethod comprises the following steps of S1: obtaining two sets of measurement data, namely DL data and DN data, of a first positioning device and a second positioning device; S2: calculating the distance d1 between the first positioning device to a reference point P and the distance d2 between the second positioning device to the reference point P; S3: performing Kalman treatment on the two setsof data to obtain an estimated optimal distance; and S4: combining a predetermined coordinate of the reference point, calculating a current coordinate position of a big vehicle of the bucket wheel machine. The high-reliability stroke positioning method disclosed by the invention has the advantages of being simple in principle, easy to realize, high in reliability and the like.

Description

technical field [0001] The invention mainly relates to the technical field of fuel management, in particular to a high-reliability bucket wheel machine travel positioning method, which is mainly applicable to the management of digital coal yards. Background technique [0002] Bucket wheel stacker and reclaimer is a heavy equipment for stacking and picking up bulk materials, and is often used for stacking and picking up fuel in thermal power plants and coal plants. The stacking and retrieving actions of bucket wheel machines require precise operation to ensure the accuracy of material stacking. Bucket wheel machines generally ensure the accuracy of stacking and retrieving positions through real-time feedback of stroke (walking position) information. In addition, with more and more unattended applications of the bucket wheel machine, the reliable positioning of the stroke positioning provides a guarantee for the safe operation of the bucket wheel machine. [0003] There are t...
