In a kind of specific embodiment of the present invention, the embodiment of the present invention provides a kind of for coalcutter coal cutting operation safety
Alarm method, comprising:
Step S11: the real time video image of coalcutter is obtained；
Step S12: according to real time video image, judge whether the coalcutter is in running order；
Step S13: if the coalcutter is in running order, it is determined that the corresponding danger zone of the coalcutter；
Step S14: judge the danger zone whether someone, if it is determined that described danger zone someone, then issue safety
Alarm signal.
In embodiments of the present invention, it is necessary first to obtain the real time video image of coalcutter, certainly, actually shot
When, it is needed to coalcutter in working condition due to subsequent, the danger zone of surrounding is determined, therefore the real time video image
In, it should the peripheral region including coalcutter.When actually carrying out the acquisition of real time video image, due to the Special Ring in coal mine
Border can reliably get the real time video image of the coalcutter in coal mine therefore, it is necessary to use high-definition anti-explosion video camera.
After getting real time video image, it can be determined that whether coalcutter is in running order, only at coalcutter
When working condition, just can be carried out subsequent staff whether danger zone dangerous operation judgement because, actual
In coal production, when coalcutter coal cutting process, operating personnel is in danger zone when operation, and wall caving coal caused by coal wall caving is
It may kill and injure operating personnel by a crashing object；Coal mining machine roller rotates coal cutting, and the coal that roller is thrown away is likely to hit operating personnel, causes people
Member's casualties.
Whether the judgement of operation is specific progress coalcutter, can be compared according to the real time video image that front and back two is opened
Right, whether the position of the position, two rollers that judge the coalcutter in two real time video images changes, to judge coalcutter
It is whether in running order, naturally it is also possible to using other determination methods.
When determining that coalcutter is in running order, if there are staff to make in violation of rules and regulations for the danger zone of the coalcutter
Industry determines the corresponding danger area of the coalcutter it would be possible that therefore the injures and deaths that personnel occur can use real time video image
Whether someone if someone illustrates that this person is carrying out violation operation, therefore can issue security alarm signal to the people in domain
It is reminded, and will test someone and be sent to background devices in the real time video image of danger zone violation operation and deposit
Storage, is checked in order to which administrative staff transfer.
Further, in embodiments of the present invention, in order to determine the working condition of coalcutter, due to being opened in actual coal seam
Two roller level heights during adopting, when coalcutter is in running order, under coalcutter working condition and off working state
Difference, therefore the Rule of judgment for using two rollers of identification whether to work as coalcutter in the same horizontal line.Work as coalcutter
For two rollers not in same horizontal line, coalcutter is in running order；When two roller of coalcutter is in same horizontal line, also need to close
Whether wall supporting judges the state of coalcutter to connection cylinder face guard in place.If wall supporting in place if be shutdown status, otherwise for
Working condition.In order to judge whether the coalcutter is in running order according to real time video image, specifically, can carry out
Following steps:
Step S21: according to real time video image, first position, the second tin roller of the first roller of the coalcutter are identified
The second position；
Step S22: judge whether the first position and the second position are in same horizontal line；
Step S23: if it is not, then judging that the coalcutter is in running order.
Certainly, if it is decided that the first position and the second position are not in same horizontal line, also not necessarily illustrate
Coalcutter is in shutdown status at this time, at this moment the state of wall supporting in place whether can be in according further to face guard to determine
The state of coalcutter specifically judges whether the first position and the second position are in same horizontal line described
Later, it can also follow the steps below:
Step S31: according to real time video image, first position, the second tin roller of the first roller of the coalcutter are identified
The second position；
Step S32: judge whether the first position and the second position are in same horizontal line；If it is not, then
Judge that the coalcutter is in running order；
Step S33: if it is, judging that corresponding first face guard of first roller and the second tin roller are corresponding
Whether the second face guard is in wall supporting state；If so, judging that the coalcutter is in shutdown status；If it is not, then judging institute
It is in running order to state coalcutter.
It, at this moment can not one that is, when the first position and the second position are in same horizontal line
Surely determine that coalcutter is in off working state, at this moment can continue to judge whether face guard is in wall supporting state, judge coalcutter
State.If face guard is not in wall supporting state, illustrate that coalcutter is working, it is in running order；If wall supporting
Plate is in wall supporting state, then illustrating that coalcutter is in off working state.
Further, when actually carry out the first roller and second tin roller whether judgement in the same horizontal line when, by
In the error of mechanical equipment itself and the error of image recognition, it can permit the first roller at this time and second tin roller exist centainly
Difference in height in range.Specifically, it can follow the steps below:
Step S41: whether within a preset range to judge the difference in height of the first position and the second position；
Step S42: if it is, judging that the first position and the second position are in same horizontal line；
Step S43: if it is not, then judging that the first position and the second position are not in same horizontal line.
That is, even if first position and the second position there are differences in height, as long as but the difference in height in default model
In enclosing, then also can be determined that the first position of first roller and the second position of second tin roller are in same horizontal line.
Specifically, for the setting of preset range, 1/10th of the height value in the size of roller itself be can be set as, certainly
Other numberical ranges can be set.
Specifically, four that algorithm of target detection identifies the bezel locations of two roller of coalcutter in every picture be can use
Parameter: the coordinate (bx1, by1) of the first position of the first roller, height value bh1, the width value bw1 of the first roller；Second tin roller
The second position coordinate (bx2, by2), height value bh2, the width value bw2 of the first roller.If the by1's and by2 of two rollers
/ 10th of/10th or bh2 of the difference less than bh1 are (in practice, for same coalcutter, bh1=bh2, bw1=
Bw2, that is to say, that the first roller is identical with the size of second tin roller), then illustrate two rollers in the same horizontal line.
On the basis of above-mentioned specific embodiment, in the present embodiment, in order to determine danger zone with the presence or absence of work in violation of rules and regulations
The staff of industry can carry out step:
Step S51: feature candidate region is formed in the danger zone of the real time video image；
Step S52: judge whether the feature in the feature candidate region meets and preset humanoid feature or default face spy
Sign；
Step S53: if it is, judging someone in the danger zone；If it is not, then judge the danger zone without
People.
That is, face characteristic or humanoid feature have been detected whether in the default monitoring range of real time video image,
If there is face characteristic or humanoid feature, then illustrating that the region is likely that there are operating personnel, then peace should be issued at this time
Full alarm signal, if without face characteristic or humanoid feature, it can also be pre- to detect this using other detection methods
If whether having staff in monitoring range.
Further, in order to be determined to the corresponding danger zone of the coalcutter, the step of can carrying out, is as follows:
Step S61: according to real time video image, the first roller, the second tin roller of the coalcutter are identified；
Step S62: according to real time video image, the third of the preset quantity hydraulic support on the outside of first roller is identified
4th position of the preset quantity hydraulic support on the outside of position, the second tin roller；
Step S63: the 5th position of the pedestal of the preset quantity hydraulic support and the 6th position, described of coal wall are utilized
The third place, the 4th position form rectangular area, obtain the corresponding danger zone of the coalcutter.
In the present embodiment, it is necessary first to identify the first roller and second tin roller of coalcutter, and the first roller and second
Roller is set to the two sides of coalcutter, specifically, can use algorithm of target detection and rolls to the coalcutter first in every picture
Cylinder direction coalcutter lateral direction 5 frame hydraulic supports to second tin roller be directed toward coalcutter lateral direction 5 frame hydraulic supports with
The rectangular extent that bracket base to the coal wall region of working face is formed in front of hydraulic support column carries out recognition detection, and with red
Rectangle frame is marked.It is of course also possible to be other default risk ranges, can may be made according to the coalcutter of practical model
At danger zone set.Coalcutter lateral direction is directed toward for the first roller, does illustrate here, for the first rolling
For cylinder, the first roller is directed toward the direction that the direction of second tin roller is directed toward on the inside of coalcutter for the first roller.Therefore, the first roller
It is directed toward the direction on the outside of coalcutter, the direction opposite each other with the first roller direction for being directed toward second tin roller.Second tin roller is directed toward
The direction of the first roller also opposite each other direction is directed toward with second tin roller in direction on the outside of coalcutter.
