Abstract
The utility model is applicable to radio frequency identification equipment technical field, provide a kind of radome for radio frequency identification equipment, formed by metal material manufacture, there is radio frequency identification equipment radome inside, radome comprises shield door, shield door is positioned on the direction of the outside emitting electromagnetic wave of radio frequency identification equipment, and shield door is pasted with absorbing material on a side of radio frequency identification equipment.The direction that radome of the present utility model is positioned at the outside emitting electromagnetic wave of radio frequency identification equipment is provided with shield door, and shield door is pasted with absorbing material on a side of radio frequency identification equipment.Absorbing material has the effect of scattering and Transmission Attenuation to electromagnetic wave, thus avoids radome reflection electromagnetic wave, makes equipment have read write line normally to work.
Description
Technical field
The utility model belongs to technical field of RFID, particularly relates to a kind of radome for radio frequency identification equipment.
Background technology
Radio-frequency (RF) identification (RFID) is a kind of wireless communication technology, can read and write related data by radio signals identification specific objective, and without the need to setting up machinery or optical contact between recognition system and specific objective.Wireless signal is the electromagnetic field by furnishing radio frequency, and data are sent out from the label be attached to article, with automatic Identification and these article of tracking.Label contains the information of Electronic saving, can identify within several meters.
After label enters magnetic field, receive the radiofrequency signal that plug-in reader sends, the energy obtained by means of induction current sends out storage product information in the chips (Passive Tag by antenna, passive label or passive label), or initiatively send the signal (Active Tag, active label or active tag) of a certain frequency; Plug-in reader reads information and after decoding, delivers to read write line and carry out relevant data process.
The applied environment of radio frequency identification equipment is a lot, and when there is electromagnetic interference (EMI) outside, or under the particular surroundings such as liquid and metal, its performance can be greatly affected.Therefore, need the radome that metal is set to shield interference, but, if there is metallic object to stop on the direction of the outside emitting electromagnetic wave of RFID device, the electromagnetic wave that RFID device is launched will be easy to produce reflection, the normal work of interference read write line, causes the problem that RFID device lost efficacy.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of radome for radio frequency identification equipment, and the radome being intended to solve radio frequency identification equipment of the prior art can reflect electromagnetic wave, affects the problem of the normal work of read write line.
The utility model realizes like this, a kind of radome of radio frequency identification equipment, formed by metal material manufacture, there is radio frequency identification equipment described radome inside, described radome comprises shield door, described shield door is positioned on the direction of the outside emitting electromagnetic wave of described radio frequency identification equipment, and described shield door is pasted with absorbing material on a side of radio frequency identification equipment.
Further, described absorbing material is pyramid absorbing material.
Further, described absorbing material comprises carbon black and fire retardant.
Further, described shield door is a sheet metal.
Further, a side of described shield door is rotatably installed on described radome, and another side relative with described side can lock on described radome.
Further, described shield door is provided with hinge, a side of described shield door is rotatably installed on described radome by described hinge.
Further, described shield door is provided with locking part, another side relative with described side locks on described radome by described locking part.
Compared with prior art, beneficial effect is the utility model: the direction that radome of the present utility model is positioned at the outside emitting electromagnetic wave of radio frequency identification equipment is provided with shield door, and shield door is pasted with absorbing material on a side of radio frequency identification equipment.Absorbing material has the effect of scattering and Transmission Attenuation to electromagnetic wave, thus avoids radome reflection electromagnetic wave, makes equipment have read write line normally to work.
