实施例1如图1所示，一种可视式超高频RFID通道机，包括工控主机1、RFID读写器2、天线3和输送设备4，工控主机1和RFID读写器2相连，RFID读写器2和天线3相连，其特征在于还包括屏蔽区域5和屏蔽帘6，该屏蔽区域5内布置天线3，输送设备4的输送路径穿过屏蔽区域5内部，屏蔽区域5在输送设备4的两端安装有屏蔽帘6，该屏蔽区域5是由金属丝网7包裹，其中金属丝网7使用导电金属材料制成。Embodiment 1 As shown in FIG. 1, a visual UHF RFID channel machine includes an industrial control host 1, an RFID reader 2, an antenna 3, and a conveying device 4, and the industrial control host 1 and the RFID reader 2 are connected. The RFID reader 2 is connected to the antenna 3, and is also characterized in that it further includes a shielding area 5 and a shielding curtain 6, in which the antenna 3 is arranged. The conveying path of the conveying device 4 passes through the inside of the shielding area 5, and the shielding area 5 is in conveyance. A shielding curtain 6 is installed at both ends of the device 4, and the shielding area 5 is wrapped by a metal wire mesh 7, wherein the metal wire mesh 7 is made of a conductive metal material.
使用导电金属材料做成的金属丝网7的原理是：（1）、电磁波是由变化的电场和变化的磁场组成，变化的磁场产生电场，变化的电场产生磁场，二者缺一不可，否则就无法传播；（2）、当空中电场在金属丝网7的周围形成后，由于导电金属的短路作用，破坏了电场的形成（理想情况是导电介质电阻为零，电场被短路完全消失）。The principle of the metal mesh 7 made of conductive metal material is: (1) The electromagnetic wave is composed of a changed electric field and a changed magnetic field. The changed magnetic field generates an electric field, and the changed electric field generates a magnetic field. (2) When the aerial electric field is formed around the wire mesh 7, the formation of the electric field is destroyed due to the short circuit of the conductive metal (ideally, the resistance of the conductive medium is zero, and the electric field is completely eliminated by the short circuit).
金属丝网7使用常见的导电材料有铁，或铜，或铝，或铁合金，或铜合金，或铝合金等。A common conductive material used for the metal mesh 7 is iron, or copper, or aluminum, or an iron alloy, or a copper alloy, or an aluminum alloy.
基于上述两点，电磁波到达金属丝网7区域后，电场消失，无法继续产生磁场，从而截断了电磁波的继续传播。屏蔽区域5使用金属丝网7包裹后，形成密闭系统，则电磁波无法进入该密闭系统，因此形成屏蔽效应。如果金属丝网7不是密闭系统，由于电磁波的衍射效应，还是有部分电磁波绕过金属丝网7进入，此时屏蔽效果很差。如果金属丝网7没被接地，则电场到达该区域后，它仍旧能对大地形成电场，形成新的电磁波，因此，金属丝网7接地，屏蔽效果更好。Based on the above two points, after the electromagnetic wave reaches the area of the metal wire mesh 7, the electric field disappears and it is no longer possible to generate a magnetic field, thereby blocking the continued propagation of the electromagnetic wave. After the shielding area 5 is wrapped with the metal wire mesh 7 to form a closed system, electromagnetic waves cannot enter the closed system, so a shielding effect is formed. If the metal wire mesh 7 is not a closed system, due to the diffraction effect of electromagnetic waves, some electromagnetic waves still bypass the metal wire mesh 7 to enter, and the shielding effect is poor at this time. If the wire mesh 7 is not grounded, after the electric field reaches the area, it can still form an electric field to the ground and form a new electromagnetic wave. Therefore, the wire mesh 7 is grounded, and the shielding effect is better.
由于金属丝网1具有柔韧性，因此屏蔽区域5可以由导电金属骨架内镶嵌金属丝网1搭建而成，使用导电金属骨架可以保证屏蔽区域5整体上结实、美观。Because the metal mesh 1 is flexible, the shielding area 5 can be constructed by inlaying the metal mesh 1 in a conductive metal skeleton, and the use of the conductive metal skeleton can ensure that the shielding region 5 is strong and beautiful overall.
屏蔽区域5也可以由玻璃或夹胶玻璃搭建而成，使用玻璃时，将金属丝网7粘贴在玻璃的内侧或外侧。使用夹胶玻璃时，将金属丝网7安装在夹胶玻璃的夹层内。The shielding area 5 may also be constructed of glass or laminated glass. When the glass is used, the wire mesh 7 is pasted on the inside or outside of the glass. When using laminated glass, the wire mesh 7 is installed in the interlayer of laminated glass.
金属丝网7的目数与天线3发射信号的波长对应。为了使屏蔽效果更好，可以使用双层金属丝网7。The mesh number of the metal mesh 7 corresponds to the wavelength of the signal transmitted by the antenna 3. In order to make the shielding effect better, a double-layer metal wire mesh 7 can be used.
现有屏蔽帘或屏蔽门使用金属面板，例如不锈钢板，成本高，机械机构复杂，开关门速度慢，影响检测效率。The existing shielding curtain or shielding door uses a metal panel, such as a stainless steel plate, which has high cost, complicated mechanical mechanism, slow door opening and closing speed, and affects detection efficiency.
屏蔽帘6同理采用金属丝网7制作，屏蔽效果更好。屏蔽帘6由透明柔性材料制成，柔性材料的侧面或夹层上粘贴有金属丝网7。The shielding curtain 6 is similarly made of the metal wire mesh 7, and the shielding effect is better. The shielding curtain 6 is made of a transparent flexible material, and a metal mesh 7 is pasted on the side or the interlayer of the flexible material.
由于输送设备4上的物体通过屏蔽帘6后，会将屏蔽帘6撑开一个缺口，导致电磁波泄露，为此，屏蔽帘6由两个或两个以上的屏蔽带组6-1构成，每个屏蔽带组6-1由屏蔽带6-1-1依次连接，屏蔽带组6-1之间在整体上交错布置。屏蔽带组6-1交错布置后，可以有效遮挡电磁波。As the object on the conveying device 4 passes through the shielding curtain 6, it will open a gap in the shielding curtain 6, causing electromagnetic waves to leak. To this end, the shielding curtain 6 is composed of two or more shielding tape groups 6-1. The shielding tape groups 6-1 are sequentially connected by the shielding tape 6-1-1, and the shielding tape groups 6-1 are staggered as a whole. After the shielding tape group 6-1 is staggered, it can effectively shield electromagnetic waves.
