Description
【Technical field】
The invention belongs to pressing equipment security fields, and in particular to one kind is divert one's attention when preventing pressing equipment operating personnel from working
Equipment and its method of work.
【Background technology】
According to relevant information, the personal injury occurred on lathe is more three times higher than common mechanical industry, every in press workshop
There are 20% worker injuries year, and most accident occurs what is caused in mini-type punching equipment particularly crank press.
Often the operating time time repeats several actions to pressing equipment operating personnel, and working environment is poor.Therefore it is easy for
Divert one's attention during work, but because work diverts one's attention to be possible to cause serious industrial accident.Common pressing equipment protector
All it is that this also can bring certain influence simultaneously to the operation of operating personnel simultaneously in pressing equipment working region addition guard rail etc.
Reduce operating efficiency.Therefore operating personnel may produce certain repulsion psychology to guard rail.
【The content of the invention】
It is an object of the invention to overcome it is above-mentioned it is not enough there is provided it is a kind of prevent the pressing equipment operating personnel from working when divert one's attention
Equipment and its method of work, the equipment investment expense is few, be adapted to large-scale promotion, and its method of work that shows the way is intelligent, convenient
Change, without operation, and reliability is high.
In order to achieve the above object, it is a kind of to prevent the equipment divert one's attention when pressing equipment operating personnel work, including with opening
Close and be provided with eye tracker on the pressing equipment of button and scram button, pressing equipment, eye tracker and shift knob are equal
Connect CPU processor, CPU processor control scram button.
The eye tracker is two, is separately positioned on the both sides of pressing equipment, and just to operating personnel's face.
The CPU processor electrically connects eye tracker by USB interface.
The CPU processor electrically connects the shift knob and scram button of pressing equipment by I/O interfaces.
The eye tracker is the contactless eye motion trackers of faceLAB5.
The CPU processor uses model S3C2410 ARM9 processors.
A kind of method of work for the equipment for preventing from diverting one's attention during pressing equipment operating personnel work, comprises the following steps：
Step one, according to pressing equipment, the work watching area of operating personnel is calibrated on eye tracker；
Step 2, CPU processor is detected after pressing equipment unlatching, and CPU processor starts eye tracker work；
Step 3, eye tracker gathers the blinkpunkt of operating personnel in the work watching area calibrated in real time；
Step 4, the blinkpunkt of the operating personnel collected and the working region of demarcation is contrasted, if operating personnel
Blinkpunkt repeated in working region, then to step 3；If the blinkpunkt of operating personnel is beyond working region and punching press
Equipment is also working on, then into step 5；
Step 5, the emergency stop switch of CPU processor control pressing equipment closes pressing equipment.
When the shift knob that CPU processor detects pressing equipment closes pressing equipment, and eye tracker was at 30 minutes
Within be not detected by the eye motion situation of people, CPU processor just closes eye tracker.
Eye tracker is two, when any one operating personnel collected blinkpunkt beyond working region and
Pressing equipment is also working on, then into step 5.
Compared with prior art, equipment of the invention mainly uses eye tracker, CPU processor, and eye tracker is not
In the working region of pressing equipment, the normal work of operating personnel is not interfered with, eye tracker is on automobile driving safe
With should for many years, by the development in several generations, extraction to the blinkpunkt of the eyes of people and by the blinkpunkt of people and watching area area
Domain have accumulated rich experience, can be transplanted to well in the protection of the operating personnel of pressing equipment, the throwing of this setting
Rate are few, design is simple, reliability is high.
The method of the present invention is to gather the blinkpunkt of operating personnel by eye tracker, will collect data and sends to
CPU processor, CPU processor contrasts the working region of the blinkpunkt of the operating personnel collected and the pressing equipment of setting,
If it was found that the blinkpunkt of operating personnel have left the working region of pressing equipment and pressing equipment is still in work, being considered as
At this moment operating personnel divert one's attention, and CPU processor controls scram button to stop equipment immediately, and pressing equipment is operated for high ensure that
The work safety of personnel, it is to avoid because operating personnel divert one's attention produced accident.
Further, the present invention is acquired using two eye trackers, dual can ensure to divert one's attention in operating personnel
When emergency shutdown, improve the security of the present apparatus.

Fig. 2 is System Control Figure of the invention；
Wherein, 1, eye tracker；2nd, pressing equipment；3rd, CPU processor；4th, shift knob；5th, scram button.
【Embodiment】
The present invention will be further described below in conjunction with the accompanying drawings.
Referring to Fig. 1 and figure, a kind of equipment for preventing from diverting one's attention during pressing equipment operating personnel work, including with shift knob
4 and the pressing equipment 2 of scram button 5, eye tracker 1 is provided with pressing equipment 2, and eye tracker 1 and shift knob 4 are equal
CPU processor 3 is connected, the control scram button 5 of CPU processor 3, CPU processor 3 electrically connects eye tracker by USB interface
1, CPU processor 3 electrically connects the shift knob 4 and scram button 5 of pressing equipment 2 by I/O interfaces, and eye tracker 1 is
The contactless eye motion trackers of faceLAB5, CPU processor 3 uses model S3C2410 ARM9 processors.
It is preferred that, eye tracker 1 is two, is separately positioned on the both sides of pressing equipment 2, and just to operating personnel face
Portion.
A kind of method of work for the equipment for preventing from diverting one's attention during pressing equipment operating personnel work, comprises the following steps：
Step one, according to pressing equipment 1, the work watching area of operating personnel is calibrated on eye tracker 1；
Step 2, CPU processor 3 is detected after pressing equipment unlatching, and CPU processor 3 starts eye tracker 1 and worked；
Step 3, eye tracker 1 gathers the blinkpunkt of operating personnel in the work watching area calibrated in real time；
Step 4, the blinkpunkt of the operating personnel collected and the working region of demarcation is contrasted, if operating personnel
Blinkpunkt repeated in working region, then to step 3；If the blinkpunkt of operating personnel is beyond working region and punching press
