The purpose of this utility model is achieved by the following technical solution: case is preserved in a kind of temperature adjustment that RFID antenna is housed, comprise the RF Reader that casing, RFID antenna, RFID antenna connect, it is characterized in that described RFID antenna is arranged in the box liner chamber.
Described RFID antenna is arranged in the casing on inner bag rear wall or the inner bag bottom surface.
Described RFID antenna is arranged on the rack in the inner bag chamber.
Described RFID antenna is connected to RF Reader from casing rear portion exit, RF Reader reads the information of RF tag on the article in the box liner, several article are arranged in the real-time detection case, and takeaway reduces or puts into present case and the information that can learn article after the increase.
Described rack is frame structure or slab construction, and RFID antenna is arranged between rack end face or bottom surface or the rack interlayer.
Described rack is the tubule frame structure that is welded, and RFID antenna penetrates in the tubule of rack.
Described RFID antenna has protecting pipe outward.
Described RFID antenna has two at least, and setting is arranged in parallel.
Described RFID antenna is at least two square frame shape or annulars that size is different, and the big snare ringlet of antenna is arranged in the casing on inner bag rear wall or the inner bag bottom surface.
Described RFID antenna is at least two square frame shape or annulars that size is different, and the big snare ringlet of antenna is arranged on the rack.
The utility model compared with prior art is equipped with following advantage 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, RFID antenna of the present utility model is arranged in the temperature adjustment preservation box body inner bag chamber, or be arranged on box liner rear wall or the inner bag bottom surface, or be arranged on the rack in the box liner, making full use of temperature adjustment preservation case inner part fixes up an aerial wire, processing and fabricating is simple, be convenient to install, change and maintenance, and under the condition that original temperature adjustment preservation case mould is not changed, just can increase the radio frequency measuring ability.RFID antenna needs to transform door body structure can be on not being installed in a body.
3, when RFID antenna is arranged on temperature adjustment and preserves on the rack in the box body inner bag chamber, according to the stored goods of different volumes or shape, can regulate the position of rack easily, applicability is strong.
4, RFID antenna of the present utility model is connected to RF Reader from casing rear portion exit, article to band RF tag in the case detect in real time, the information that the correlation frequency marking is signed reads, several article are arranged in the real-time detection case, and takeaway reduces or puts into present case and the information that can learn article after the increase.Just can identify when the user takes article away, RF Reader can send to control panel with information, carries out remote monitoring by the control panel process information or by network.

Among the figure: 1, detected article; 2, RF tag; 3, RF Reader; 4, rack; 5, casing; 6, RFID antenna.
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, Fig. 2, the embodiment of the refrigerator of RFID antenna is housed for the utility model is a kind of, mainly comprise the casing 5 that foaming layer is housed, two racks 4 are up and down arranged in the casing 5, on two racks 4, RFID antenna 6 is set all.RFID antenna 6 on each rack 4 has many, and the (see figure 2) that is arranged in parallel.RFID antenna 6 also can be the different square frame shape of a plurality of sizes or annular or other geometry, and the big snare ringlet of antenna is arranged on the rack 4.
Do not have the temperature adjustment of rack (or rack is arranged) to preserve case for some, RFID antenna 6 also can be arranged in the casing 5 on inner bag rear wall or the inner bag bottom surface.RFID antenna 6 on inner bag rear wall or the inner bag bottom surface can be provided with many, and is arranged in parallel.RFID antenna 6 also can be the different square frame shape of a plurality of sizes or annular or other geometry, and the big snare ringlet of antenna is arranged on inner bag rear wall or the inner bag bottom surface.
Above-mentioned RFID antenna 6 is connected to RF Reader 3 from casing 5 rear portion exits, RF Reader 3 is fixed on the casing 5 back plates, information on the RF tag 2 of 3 pairs of detected article 1 of RF Reader reads, several article 1 are arranged in the real-time detection casing 5, can learn the present case and the information of article 1 after article 1 are taken minimizing away or put into increase.
Each rack 4 can be the single or multiple lift frame structure, also can be the single or multiple lift slab construction, and RFID antenna 6 can be arranged on rack 4 end faces or the bottom surface, and RFID antenna 6 also can be arranged between the interlayer of each multilayer rack 4.Structure as a kind of rack 4 embodiment is a double glazing unit, and RFID antenna 6 is arranged between the double glazing unit, can make RFID antenna 6 injury-free.
The structure that also has a kind of rack 4 embodiment is the tubule frame structure that is welded, and RFID antenna 6 penetrates in the tubule of rack 4.Also can make RFID antenna 6 injury-free.
When RFID antenna 6 directly is contained on the rack 4, the RFID antenna 6 outer protecting pipes that are surrounded by.
In casing 5 inner bags, can be provided with one or more racks that has RFID antenna 64.
During use, RF Reader 3 will detect article 1 state in the casing 5 inner bag chambers every 5 seconds kinds or shorter time, when taking article 1 away, the user just can identify by the information that reads article 1 RF tag 2, RF Reader 3 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, the mounting means of the utility model RFID antenna on rack 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.
