Case is preserved in temperature adjustment with RFID antenna
Technical field
The utility model relates to the improvement that case (as: refrigerator, refrigerator, wine cabinet, blood storage cabinet etc.) RFID antenna mounting structure is preserved in temperature adjustment, is that case is preserved in a kind of temperature adjustment with RFID antenna specifically.
Background technology
Existing automatic vending refrigerator has mechanical type and machinery to detect the article position variation with infrared combination, and frame for movement is fixed, and corresponding contoured article and riding position are fixed, and information content is little, and the scope of application is little.Detecting the method and apparatus of RFID tag signal in the prior art, is that every kind of product is sticked RF tag with putting into refrigerator, has the aerial array of a plurality of antennas to place in the door, and each antenna has the emission sight line.The controller work of aerial array is used to activate aerial array, makes each antenna at signal of predetermined frequency, and generates an electromagnetic field in refrigerator, makes that the label on each product is positioned.Antenna is arranged on the refrigerator door, and is the array way setting.This just needs to transform Refrigerator door structure, and it is comparatively complicated that its antenna is provided with structure, installs also inconvenient.How providing a kind of has the temperature adjustment of RFID antenna to preserve case, its RFID antenna is provided with rationally, and processing and fabricating is simple, convenient, and under the situation that the mould of original temperature adjustment preservation case is not changed, just can increase the radio frequency measuring ability, this has become the technical problem that needs to be resolved hurrily at present.
Summary of the invention
The purpose of this utility model is the deficiency that exists at prior art, provide a kind of temperature adjustment with RFID antenna to preserve case, its RFID antenna is provided with rationally, and processing and fabricating is simple, convenient, and under the condition that original temperature adjustment preservation case mould is not changed, just can increase the radio frequency measuring ability.
The purpose of this utility model is achieved by the following technical solution: case is preserved in a kind of temperature adjustment with RFID antenna, comprise the RF Reader that casing with foaming layer, RFID antenna, RFID antenna connect, it is characterized in that in the foaming layer of described casing RFID antenna being set, RFID antenna is centered around outside the inner container of icebox, and combines with foaming layer.
The above-mentioned plane, every circle RFID antenna place that is centered around on the box liner is substantially parallel with the end face of box mouth.
Described RFID antenna is connected to RF Reader from casing rear portion exit, and RF Reader can send to control panel with information, carries out remote monitoring by the control panel process information or by network.
The utility model compared with prior art has the following advantages and good effect:
1, the utility model has solved machinery and the machinery and the infrared fixed-site that detects the article existence that combines of existing automatic vending refrigerator, and article are fixed, the problem that information content is little.
2, the utility model is provided with RFID antenna in the foam box layer, and RFID antenna is centered around outside the inner container of icebox, and combines with foaming layer.RFID antenna is provided with rationally, and processing and fabricating is simple, convenient, produces installation effectiveness and improves, can one-shot forming.Preserve under the condition that the box body mould do not change in existing temperature adjustment, just can increase the radio frequency measuring ability, RFID antenna can be as not being installed in a body on needs transformation door body structure, the constraint that is subjected to also can be on not being installed in the inner bag inwall.
3, RFID antenna of the present utility model is connected to RF Reader from casing rear portion exit, detects in real time being with the article of RF tag in the case, and RF Reader just can read out the information on the RF tag of article in the casing.Just can identify when the user takes article away, RF Reader can send to control panel with information, by the control panel process information, also can carry out remote monitoring by network.
Description of drawings
Fig. 1 is the refrigerator cross-sectional view that the utlity model has RFID antenna.
Among Fig. 1: 1, detected article; 2, RF tag; 3, RFID antenna; 4, RF Reader; 5, the foaming layer of casing.
The specific embodiment
The utility model technology can be applicable to the industry of temperature adjustment industry (freeze, heat) and Item Management, preservation, sale.Now be applied on the refrigerator and illustrate.
Referring to Fig. 1, the embodiment that has the refrigerator of RFID antenna for the utility model is a kind of mainly comprises the casing with foaming layer 5, in the foaming layer 5 of casing RFID antenna 3 is set, RFID antenna 3 is centered around outside the inner container of icebox, and combines with foaming layer 5.The plane, every circle RFID antenna 3 place that is centered around on the inner container of icebox is substantially parallel with the end face of box mouth.RFID antenna 3 is connected to RF Reader 4 from casing rear portion exit, and RF Reader 4 is fixed on the after panel box.
During use, the article 1 of band RF tag 2 detect in real time in 4 pairs of refrigerators of RF Reader, during certain article 1 in the user takes refrigerator away, RF Reader 4 just can identify the article of taking away 1 according to RF tag 2, RF Reader 4 can send to control panel with information, by the control panel process information, also can carry out remote monitoring by network.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the mounting means of the utility model RFID antenna is not limited to above-mentioned giving an example, and can be applicable to multiple temperature adjustment and preserves on the case (including but not limited to refrigerator, refrigerator, wine cabinet, blood storage cabinet etc.).Those skilled in the art, in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
