Technical field
The utility model relates to wireless location technology, particularly relates to a kind of bucket wheel machine arm angle and bucket wheel relative position detection system.
Background technology
The coal unit such as fuel-burning power plant, large type coal field extensively adopts bucket wheel machine to carry out coal piling and get coal operating to coal.In order to realize the coal piling of coal yard and get coal precise management, need the three-dimensional coordinate detecting bucket wheel machine arm bucket wheel foremost in real time, realize being undertaken piling the real-time statistics of getting coal by coal yard diverse location.In order to calculate the three-dimensional coordinate of bucket wheel machine arm bucket wheel foremost, need to detect the angle of revolution of arm and the angle of pitch, thus calculate bucket wheel and fuselage relative to position.
The current scrambler that mostly adopts detects, and angle of revolution is detected scrambler and slewing mechanisms of bucket wheel loaders gears meshing, the angle of pitch is detected the axis of swing gears meshing of scrambler and arm.The method feature outlines as follows:
1) technology is simple, advantage of lower cost;
2) due to severe outdoor and dust atmosphere, cause gear train inevitably to occur trackslipping, the problem such as malfunctioning, stall, and then occur measuring inaccurate;
3) due to comparatively thick physical construction transmission repeatedly, measured value precision is caused to be had a greatly reduced quality;
4) due to physical construction transmission repeatedly, inevitable hysterisis error is caused;
5) cannot self-correction, exist may be increasing cumulative errors;
6) need to increase change gear train, installation difficulty is large, and installation period is long, installs improvement cost higher;
7) field failure probability is large, and poor stability, maintenance is larger.Existing a large amount of real case proves, is no matter repacking, or the attached coder mode stroke of joining of bucket wheel machine producer in early stage and Angle Measuring Equipment, substantially in 0.5 ~ 2 year, there will be problem, over halfly must just can use by integral replacing;

Embodiment
Below in conjunction with the drawings and the specific embodiments, be described in further detail the technical solution of the utility model.
The utility model carries out the detection of bucket wheel arm angle, according to the arm angle detected and then the relative position calculating arm front end bucket wheel based on the angle direction sensor of magnetoresistive transducer, double-shaft tilt angle sensor; Adopt the mode of non-mechanical to carry out angle detection, machine rebuilding need not be carried out to bucket wheel machine.
Bucket wheel relative position detection system based on wireless location of the present utility model, comprise angle direction sensor 4, main frame is detected in bucket wheel position, angle direction sensor 5 is arranged on arm 2, bucket wheel position is detected main frame and is installed on bucket wheel machine 1 pilothouse, and the three-dimensional coordinate that arm 2 angle of revolution that main frame measures according to angle direction sensor 5 and the angle of pitch (measure arm 2 angle of revolution by magnetoresistive transducer, double-shaft tilt angle sensor measure arm 2 angle of pitch) calculate bucket wheel 4 is detected in bucket wheel position.Comprise and detect the horizontal coordinate of bucket wheel according to angle of revolution, and according to the height of angle of pitch bucket wheel.
As shown in Figure 1, a is the angle of revolution detected, p is angle of revolution offset, and arm length is known is designated as L, if bucket wheel machine fuselage positions coordinate is known be designated as (0, Y
0), then the horizontal coordinate of bucket wheel position is:
