Embodiment Construction

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

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

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

[0043] S2: Calculate the first positioning device and the second positioning device to the distance D1, D2 of the reference point P;

[0044] S3: Galman filtering processing for two sets of data is given the best distance;

[0045] S4: Combined with a predetermined reference point coordinate calculation of the current coordinate position of the big wheel.

[0046] In the above step S1, the two sets of measurement data A data of the first positioning device and the second positioning devic...

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 present invention relates to the field of fuel management, referring to a highly reliable bucket stroke positioning method, mainly suitable for the management of digital coal yards. Background technique [0002] The bucket reiler is a heavy-duty device for bulk material stacking and picking, which is commonly used in the stack of fuels in the coal mill of fire power plant. Turner stack, refueling action requires accurate operation to ensure accuracy of material stack, the bucket is generally guaranteed by real-time feedback stroke (walking position) information to ensure accuracy of the position position. In addition, as the bucket is unattended, there is more and more, the reliable positioning of the stroke positioning is guaranteed for the safety operation of the bucket. [0003] There are two main ways to measure the measurement itinerary: [0004] 1. Encoder: Move the encoder to rotate when the bucket is walking thus. This method is short-distance, ...
