Description
Technical field
The anti-intrusion inspection in region is reprinted the present invention relates to the safety control in a kind of enterprise, in especially a kind of pipeline
Survey device.
Background technique
With flourishing for auto industry, requirement of the automaker to safety in production is higher and higher, grating conduct
One professional safety equipment, plays important role in Hyundai Motor manufacturing shop.
Reprinting region in automobile conveying is very important part, the automaticity of robot and the non-close in region
Property so that its is there is very big security risk, existing safety control be difficult to distinguish be equipment normally enter or it is artificial
It is improper to swarm into.
Summary of the invention
For the deficiencies in the prior art, the present invention provide it is a kind of based on combined photo switch and the anti-of grating invade
Enter detection device, be capable of detecting whether that someone walks to swarm into and reprint region, prevents someone in equipment running process from swarming into reprinting region
The problem of causing personal injury.The technical solution adopted by the present invention is that:
A kind of anti-intrusion detection device based on combined photo switch and grating, including controller, input module, two pairs
Correlation optoelectronic switch, grating；
Two pairs of correlation optoelectronic switches and grating are mounted on before safety guard net inlet；Two pairs of correlation optoelectronic switches
The optical path of the setting of optical path skewed crossing, grating is laterally arranged, and positioned at the optical path crosspoint of two pairs of correlation optoelectronic switches and two pairs
Between the Head switches of correlation optoelectronic switch；
Two pairs of correlation optoelectronic switches are about the equipment direction of advance center line bilateral symmetry for allowing access into reprinting region；
The distance between the optical path intersection point of the optical paths of two pairs of correlation optoelectronic switches and grating D1, which is less than, allows access into reprinting
The plant width D2 in region, and it is greater than human body width D 3；
The correlation optoelectronic switch is connected by input module with the input terminal of controller with grating.
Specifically, two pairs of correlation optoelectronic switches and grating mounting height are 50cm~120cm.
The present invention has the advantages that
1) present invention can effectively prevent pipeline from reprinting area people intrusion, be the simplest detection problems
Solution.
2) combined photo switch and Grating examinations device, it is simple and reliable, it is easy for installation, space is saved, and implementable
Property is strong, enhances the stability of detection device, safety improves the rate of starting, and reduces failure rate, and using effect is obvious.
Detailed description of the invention
Fig. 1 is structure composition schematic diagram of the invention.
Fig. 2 is electrical schematic diagram of the invention.
Specific embodiment
Below with reference to specific drawings and examples, the invention will be further described.
As shown in Figure 1 and Figure 2, the anti-intrusion detection device proposed by the present invention based on combined photo switch and grating, packet
Include controller 1,2, two pairs of correlation optoelectronic switches of input module 31,32, grating 4；
Two pairs of correlation optoelectronic switches 31,32 and grating 4 are mounted on before 7 inlet of safety guard net, and mounting height is
50cm~120cm；The optical path skewed crossing setting of two pairs of correlation optoelectronic switches 31,32, the optical path of grating 4 is laterally arranged, and position
In two pairs of correlation optoelectronic switches 31,32 optical path crosspoint and two pairs of correlation optoelectronic switches 31,32 Head switches a it
Between；
Two pairs of correlation optoelectronic switches 31,32 need to be about 5 direction of advance center line bilateral symmetry of automatic carriage；
The distance between the optical path of two pairs of correlation optoelectronic switches 31,32 and the optical path intersection point of grating 4 D1 are necessarily less than certainly
5 width D 2 of row trolley, and it is greater than human body width D 3；
Automatic carriage 5 is exactly that the equipment for reprinting region is allowed access into this example；
As shown in Figure 2: the correlation optoelectronic switch 31,32 passes through the input of input module 2 and controller 1 with grating 4
End is connected, and the controller 1 is PLC(programmable logic controller (PLC)).
Normal condition: automatic carriage 5 is prepared to enter into safety guard net 7 along equipment traffic direction, due to automatic carriage width D 2
The distance between the optical path of greater than two pairs correlation optoelectronic switches 31,32 and the optical path intersection point of grating 4 D1, therefore can trigger simultaneously
Two pairs of correlation optoelectronic switches 3 and grating 4, controller PLC 1 judges to be normal at this time, and system keeps running well.
Abnormality 1: when pedestrian 6 swarms into 7 inlet of safety guard net suddenly, due to human body width D 3 less than two pairs to penetrating
The distance between the optical path of formula optoelectronic switch 31,32 and the optical path intersection point of grating 4 D1, therefore trigger a pair of of correlation optoelectronic switch
3 and grating 4, controller PLC 1 judges as exception at this time, and system shuts down.
Abnormality 2: when pedestrian 6 swarms into 7 inlet of safety guard net suddenly, due to human body width D 3 less than two pairs to penetrating
The distance between the optical path intersection point of the optical path of formula optoelectronic switch 31,32 and grating 4 D1, therefore only trigger grating 4, at this time controller
PLC 1 judges as exception, and system shuts down.
