One, virtual gate subsystem 2
The virtual gate subsystem 2 comprises a virtual gate 4 and a grating collector 5 which are separately arranged on two sides of an area gateway and a virtual gate server 6 which is positioned in the far-end console 1, the virtual gate 4 and the grating collector 5 are arranged oppositely, and the virtual gate 4 and the grating collector 5 are in communication connection with the virtual gate server 6. The remote console 1 issues an instruction to the virtual gate server 6, or receives statistical information uploaded by the virtual gate server 6, and the virtual gate server 6 is used for starting and closing, controlling the virtual gate 4 and the grating collector 5, controlling the virtual gate 4 to emit visible gratings or control the color of the visible gratings, receiving abnormal information uploaded by the grating collector 5, and reporting the abnormal information to the remote console 1.
1. Virtual gate 4
The grating generator comprises a light source device 11 electrically connected with a grating controller 8, a plurality of spectroscopes 12 which are uniformly distributed are arranged on a main light beam 13 emitted by the light source device 11, the number of the spectroscopes 12 is the same as that of the light beam heads 10, the spectroscopes 12 correspond to the light beam heads one by one, and the main light beam 13 emitted by the light source device 11 is divided into a plurality of sub-light beams 14 by the spectroscopes 12, so that the grating is generated by one light source.
The light source device 11 can be divided into a monochromatic light source device 11 capable of emitting only one color light source and a multicolor light source device 11 capable of emitting at least two color light sources, and the different types of light source devices 11 have different structures and different advantages and disadvantages, specifically as follows:
a. monochromatic light source device 11
The monochromatic light source device 11 is preferably a monochromatic laser. Because the gate needs to send out at least two kinds of prompt messages (such as allowing and forbidding to pass through), two grating generators arranged in parallel need to be arranged in the generator shell, the light source colors sent by the monochromatic light source devices 11 arranged in the two grating generators arranged in parallel are different, and the two grating generators are both in communication connection with the grating controller 8. When the system works, only one group of raster generators are started to emit a visual raster (green) allowing the passage or a visual raster (red) forbidding the passage, so that the staff or the transport vehicles entering a working area are visually prompted. Because the monochromatic light source device 11 comprises a monochromatic laser, the heat generation around the monochromatic laser is less, the heat dissipation is fast, the requirement on the ambient temperature is relatively low, the application range is wide, but the number of other devices is large, and the cost is high.
b. Laser with multi-color light source

The half mirror 17 is a Thin Film Polarizer (TFP), and when a light ray is incident on the half mirror 17 at a brewster angle, the incident surface is a plane defined by the incident light ray and a normal line of the mirror surface, the laser light (P light) having a polarization direction parallel to the incident surface can pass through, and the laser light (S light) having a polarization direction perpendicular to the incident surface is totally reflected. Compared with the monochromatic light source device 11, the multi-color grating laser can be emitted only by arranging the group of light source devices 11 in the grating generator, the number of the auxiliary lasers 16 with different colors can be increased, the diversity of the grating colors is enriched, the requirements of various visual instructions are met, the internal structure, the equipment volume and the cost of the equipment are greatly reduced, and the laser with one color is only emitted during working so as to prompt the current access conditions of passing vehicles and workers.
Because the multicolor light source laser is provided with the main laser 15 and the auxiliary laser 16, heat generation around the laser is large, temperature rise is fast, the work of the laser can be influenced, and even the possibility of damaging the laser is caused, so that a heat dissipation device needs to be arranged for active heat dissipation intervention.

The sub-beams 14 pass through the beam shaping device 19, the coupling focusing device 20 and the beam head 10 from inside to outside in sequence, and the beam head 10 is longitudinally distributed on one side of the generator shell. When the optical splitter works, the controller reads the edited program to send out a control signal, the main beam 13 sent out by the light source device 11 irradiates on the first optical splitter, the first optical splitter sequentially induces to the other optical splitters, the beam shaping device 19 shapes the sub-beams 14 sent out by the optical splitters, then the coupling focusing device 20 performs coupling focusing, and finally the sub-beams are sent out by the beam head 10.
The tail end of the main light beam 13 is emitted into a light sensation sensor 21 installed in a generator shell, the light sensation sensor 21 is electrically connected with a controller and used for detecting the working condition of a laser light source, and if the light intensity change collected by the light sensation sensor 21 is large, the situation that the laser does not emit laser or the laser intensity does not reach the standard is shown, and the self-checking function is achieved.

When the remote control system works, the laser collecting device 23 senses the grating emitted by the grating generator, if any light beam in the grating is shielded, the light constant sensed by the laser collecting device 23 corresponding to any light beam is changed greatly and exceeds a set threshold value, the receiving controller 24 sends an abnormal signal to the grating controller 8 through the communication module, and the grating controller 8 forwards the abnormal signal to the remote control console 1.
The laser collecting device 23 adds an identification code to the digital signal sent by the laser collecting device 23 according to the transmission path number of the access receiving controller 24 or through the connection signal editing module 46, wherein the identification code corresponds to the laser collecting device 23 one to one for the receiving controller 24 to identify the identity of the laser collecting device 23. Because the distance between the adjacent laser acquisition devices 23 is fixed, the size and the passing position of an object passing through the grating can be measured by identifying data returned by one or a plurality of the laser acquisition devices 23 to find abnormality, so that people, non-people or vehicles can be generally identified to pass through, the data noise can be reduced, and the information accuracy can be improved.
