Abstract
The invention discloses equipment preventing operating personnel of stamping equipment from being distracted during work and a work method thereof. The method comprises the steps that an eye tracker collects fixation points of the operating personnel and transmits the collected data to a CPU, the CPU contrasts the collected fixation points of the operating personnel with the set work area of the stamping equipment, if the fixation points of the operating personnel leave the work area of the stamping equipment but the stamping equipment is still in work, then the judgment that the operating personnel are distracted can be made, the CPU immediately controls a scram button to stop the equipment, and therefore the work safety of the operating personnel of the stamping equipment is greatly guaranteed, and accidents caused by distraction of the operating personnel are avoided.
Description
[technical field]
The invention belongs to pressing equipment security fields, be specifically related to a kind of equipment of diverting one's attention when preventing pressing equipment operating personnel from working and method of work thereof.
[background technology]
According to interrelated data, the personal injury that lathe occurs is higher than common mechanical industry three times, has the worker injuries of 20% in press workshop every year, and most accident occur in mini-type punching equipment particularly crank press cause.Often the operating time time repeats several action to pressing equipment operating personnel, and working environment is poor.Therefore just easily operationally divert one's attention, but because work diverts one's attention just likely to cause serious industrial accident.Common pressing equipment protector is all add guard rail etc. in pressing equipment working region, and this brings certain impact and reduce operating efficiency also can to the operation of operating personnel simultaneously.Therefore operating personnel may produce certain repulsion psychology to guard rail.
[summary of the invention]
The object of the invention is to overcome above-mentioned deficiency; a kind of equipment of diverting one's attention when preventing pressing equipment operating personnel from working and method of work thereof are provided, this equipment investment expense is few, be applicable to large-scale promotion, its method of work that shows the way; intellectuality, facilitation, without the need to operation, and reliability is high.
In order to achieve the above object, a kind of equipment of diverting one's attention when preventing pressing equipment operating personnel from working, comprise the pressing equipment with shift knob and scram button, pressing equipment is provided with eye tracker, eye tracker and shift knob are all connected CPU processor, and CPU processor controls scram button.
Described eye tracker is two, is separately positioned on the both sides of pressing equipment, and just to operating personnel's face.
Described CPU processor is electrically connected eye tracker by USB interface.
Described CPU processor is electrically connected shift knob and the scram button of pressing equipment by I/O interface.
Described eye tracker is the contactless eye motion tracker of faceLAB5.
Described CPU processor employing model is the ARM9 processor of S3C2410.
A method of work for the equipment of diverting one's attention when preventing pressing equipment operating personnel from working, comprises the following steps:
Step one, according to pressing equipment, eye tracker calibrates the work watching area of operating personnel;
Step 2, after CPU processor detects that pressing equipment is opened, CPU processor starts eye tracker work;
Step 3, the blinkpunkt of operating personnel in the work watching area that eye tracker Real-time Collection calibrates;
Step 4, contrasts the blinkpunkt of the operating personnel collected and the working region of demarcation, if the blinkpunkt of operating personnel is in working region, then repeats to step 3; If the blinkpunkt of operating personnel beyond working region and pressing equipment also working on, then enter step 5;
Step 5, pressing equipment cuts out by the emergency stop switch that CPU processor controls pressing equipment.
When CPU processor detects that the shift knob of pressing equipment cuts out pressing equipment, and eye tracker did not detect the eye motion situation of people within 30 minutes, and eye tracker is just closed by CPU processor.
Eye tracker is two, when the blinkpunkt of any one operating personnel collected beyond working region and pressing equipment also working on, then enter step 5.
Compared with prior art; equipment of the present invention mainly adopts eye tracker, CPU processor; eye tracker is not in the working region of pressing equipment; the normal work of operating personnel can not be affected; eye tracker is used on automobile driving safe should be for many years; through the development of good several generations; to the extraction of the blinkpunkt of the eyes of people with the blinkpunkt of people and watching area region be have accumulated rich experience; can be transplanted to well in the protection of the operating personnel of pressing equipment, the investment cost of this setting is few, simplicity of design, reliability be high.
Method of the present invention is gathered by eye tracker by the blinkpunkt of operating personnel, data will be collected and send CPU processor to, the working region of the blinkpunkt of operating personnel collected and the pressing equipment of setting contrasts by CPU processor, if find the blinkpunkt of operating personnel have left the working region of pressing equipment and pressing equipment still in work, just think that at this moment operating personnel divert one's attention, CPU processor controls scram button immediately makes equipment stop, the high work safety that ensure that pressing equipment operating personnel, avoid because operating personnel divert one's attention produced accident.
Further, the present invention adopts two eye trackers to gather, and dually can ensure the emergency shutdown when operating personnel divert one's attention, improve the security of this device.

[detailed description of the invention]
Below in conjunction with accompanying drawing, the present invention will be further described.
See Fig. 1 and Tu, a kind of equipment of diverting one's attention when preventing pressing equipment operating personnel from working, comprise the pressing equipment 2 with shift knob 4 and scram button 5, pressing equipment 2 is provided with eye tracker 1, eye tracker 1 is all connected CPU processor 3 with shift knob 4, CPU processor 3 controls scram button 5, CPU processor 3 is by USB interface electrical connection eye tracker 1, CPU processor 3 is electrically connected shift knob 4 and the scram button 5 of pressing equipment 2 by I/O interface, eye tracker 1 is the contactless eye motion tracker of faceLAB5, CPU processor 3 adopts model to be the ARM9 processor of S3C2410.
Preferably, eye tracker 1 is two, is separately positioned on the both sides of pressing equipment 2, and just to operating personnel's face.
A method of work for the equipment of diverting one's attention when preventing pressing equipment operating personnel from working, comprises the following steps:
Step one, according to pressing equipment 1, eye tracker 1 calibrates the work watching area of operating personnel;
Step 2, after CPU processor 3 detects that pressing equipment is opened, CPU processor 3 starts eye tracker 1 and works;
Step 3, the blinkpunkt of operating personnel in the work watching area that eye tracker 1 Real-time Collection calibrates;
