Description
Technical field
The present invention relates to a kind of automatic cut system and method for coal-winning machine, specifically a kind of coal mining based on infrared thermal imaging
Machine automatic cut system and method, belongs to coal-winning machine cut control technology field it is adaptable to have the coal mining of memory cut function
Machine.
Background technology
The identification of coal rock for coal cutter interface is the key that coal-winning machine is capable of Automated condtrol.Due to Direct Recognition coal petrography circle
Face has sizable difficulty it is impossible to meet the requirement at coal work scene, how to carry out coal petrography using round-about way at this stage
Interface identifies, the method for current indirect identification coal-rock interface mainly has memory cut method and cut KLR signal approach two big class.
Memory cut method is applied to top, base plate than shallower working face of coal seam, and the principle of this technology is to be grasped by coal-winning machine
Make personnel's manipulation coal-winning machine to work in advance one along work surface coal seam height fluctuation condition and circulate, coal mining machine controller is sampled and deposited
Store up the running parameter of cycle of operation first, and in several limited cut circulation afterwards, coal-winning machine is stored according to controller
The running parameter automatic operating of memory, roller height is also adjusted automatically, but due to actual condition of coal seam occurrence ratio
More complicated, acutely, the cutting resistance curves remembered do not have universality, thus make on coal mine work area merely for coal-rock interface change
Application effect with memory cut technology is unsatisfactory.
Cut KLR signal approach is automatically to carry out coal cutting using the coal-winning machine with memory cut function, simultaneously using sensing
Device gathers coal-winning machine and runs the signal producing as cylinder cut force signal, pick stress signal, current signal, temperature signal etc.,
Then using some intelligent algorithms, the cut state recognition of coal-winning machine for coal cutting and is cut a rock both of which, also coal-winning machine is cut
The result cutting state recognition more refines, and presses close to real coal-winning machine cut situation, and recognition result is divided into cut hard coal seam, cut
The operating modes such as top board, cut dirt band and cut tomography.Increase now with coal mining acc power and the improvement of pick material, for keeping
Top, the planarization of base plate, less dirt band and tomography to hardness, typically take directly carry out strength cut and not according still further to coal petrography
Interface adjusts roller height.
Above cut KLR signal approach can identify the cut state of coal-winning machine in the case of the overwhelming majority, for example
When the cut state recognizing coal-winning machine using intelligent algorithm tends to abnormal, coal-winning machine is automatic or manual to be adopted either manually or by regulation
Coal machine travel speed and adjustment coal mining machine roller height, make coal-winning machine cut recovering state to normally.But due to ocurrence of coal seam
Condition has the features such as uncertainty and complexity, and intelligent algorithm can not be recognized accurately the cut state of coal-winning machine sometimes,
The erroneous judgement of cut state recognition result can be caused；And the sensor of some measurement cut signals is also easy to by external factor
Interference, causes the inaccurate of cut signal measurement, thus the cut state of coal-winning machine also cannot be recognized accurately.
