Embodiment 1
As shown in Figure 1, a kind of visual ultrahigh frequency RFID channel machine, including industrial control host 1, RFID reader 2, antenna 3
With conveying equipment 4, industrial control host 1 is connected with RFID reader 2, and RFID reader 2 is connected with antenna 3, it is characterised in that also wraps
Shielding area 5 and shielding curtain 6 are included, arranges that antenna 3, the transport path of conveying equipment 4 pass through shielding area 5 in the shielding area 5
Inside, shielding area 5 are equipped with shielding curtain 6 at the both ends of conveying equipment 4, which wrapped up by wire mesh 7,
Middle wire mesh 7 is made using conductive metallic material.
The principle for the wire mesh 7 being made into using conductive metallic material is: (1), electromagnetic wave be electric field and change by changing
The magnetic field of change forms, and changing magnetic field generates electric field, and the electric field of variation generates magnetic field, and Neither of the two can be dispensed, otherwise can not just pass
It broadcasts；(2), after formation around wire mesh 7 when aerial electric field, due to the short circuit effect of conductive metal, electric field is destroyed
It is formed (ideally conducting medium resistance is zero, and electric field, which is short-circuited, to be completely disappeared).
Wire mesh 7 has iron or copper or aluminium or ferroalloy or copper alloy or aluminium alloy using common conductive material
Deng.
Based on above-mentioned two o'clock, after electromagnetic wave reaches 7 region of wire mesh, electric field disappears, and can not continue to generate magnetic field, thus
Electromagnetic wave has been truncated to continue to propagate.After shielding area 5 is wrapped up using wire mesh 7, closed system is formed, then electromagnetic wave can not
Into the closed system, therefore form screen effect.If wire mesh 7 is not closed system, since the diffraction of electromagnetic wave is imitated
It answers, still has part electromagnetic wave around the entrance of wire mesh 7, shield effectiveness is very poor at this time.If wire mesh 7 is not grounded,
After then electric field reaches the region, it still can form electric field to the earth, form new electromagnetic wave, and therefore, wire mesh 7 is grounded,
Shield effectiveness is more preferable.
Since wire mesh 1 has flexibility, shielding area 5 can be by embedded with metal silk screen in conductive metal skeleton
1 builds, and can guarantee that shielding area 5 is solid, beautiful on the whole using conductive metal skeleton.
Shielding area 5 can also be built by glass or doubling glass, and when using glass, wire mesh 7 is pasted onto
The inner or outer side of glass.When using doubling glass, wire mesh 7 is mounted in the interlayer of doubling glass.
The mesh number of wire mesh 7 is corresponding with the transmitting wavelength of signal of antenna 3.In order to keep shield effectiveness more preferable, can be used
Double-level-metal silk screen 7.
Existing shielding curtain or shield door use metal decking, such as stainless steel plate, at high cost, and mechanical mechanism is complicated, switch
Door speed is slow, influences detection efficiency.
It shields curtain 6 similarly to be made of wire mesh 7, shield effectiveness is more preferable.Shielding curtain 6 is made of clear flexible material,
Wire mesh 7 is pasted on the side of flexible material or interlayer.
After passing through shielding curtain 6 due to the object on conveying equipment 4, the shielding support of curtain 6 can be opened a gap, lead to electromagnetic wave
Leakage, for this purpose, shielding curtain 6 is made of two or more shielding band group 6-1, each shielding band group 6-1 is by shielding band 6-
1-1 is sequentially connected, interlaced arrangement on the whole between shielding band group 6-1.After shielding band group 6-1 interlaced arrangement, can effectively it hide
Keep off electromagnetic wave.
