Description
Technical field
The utility model relates to technical field of RFID, specifically a kind of electronic bin RFID reader antenna assembly.
Background technology
RFID technique, also known as radio frequency identification, is a kind of communication technology, reads and writes 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.Along with the development of wireless communication technology, global positioning system, satellite system, wireless LAN communication etc. all need antenna that is lightweight, thin profile, and based on frequency expansion and many reasons such as anti-interference, the selection of antenna receives the concern of people.RFID is the non-contact data communication undertaken by wireless radio frequency mode, its core component is read write line and electronic tag, by the radio wave of read write line, the information that can store in reading electronic labels, this technology at home and abroad gets a lot of applications, and all has application in fields such as public transport, subway, campus, social securities.The quality of RFID data communication effect is mainly determined by the performance of its inside antenna, and therefore, antenna performance becomes the focus of Improvement.
Radio-frequency card oscillator signal sends through antenna, and radio-frequency card carries the set specific frequency signal of card information.Due to induction reactance and the electric capacity composition filter circuit of antenna, export the signal of filter circuit to detecting circuit, through resolving the information data obtaining radio-frequency card.According to circuit theory, the magnetic field intensity of antenna strengthens with the increase of electric current, and induced voltage and the magnetic field of antenna present proportional relation, and the coil radius, diameter of wire, Card Reader distance, conductor length etc. of antenna all can have an impact to the sensitivity of card reader.
The R&D costs of existing radio-frequency card antenna technology are relatively high, and deposit the problem of ubiquity less stable, therefore design a kind of reliable communications, cheap antenna becomes problem demanding prompt solution.
Utility model content
In view of the defect that above-mentioned prior art exists, the purpose of this utility model proposes a kind of electronic bin RFID reader antenna, possesses reliable communications, cheap feature.The purpose of this utility model will be achieved by the following technical programs:
A kind of electronic bin RFID reader antenna assembly, comprise coil, antenna element and the circuit board being connected described antenna element by coil, described coil is positive circular coil, and described positive circular hub of a spool position is provided with bar-shaped coil.
Further, described antenna element is made up of the first interlaced antenna and the second antenna the utility model, and the first antenna and the second antenna intersection location are positioned at the center of described coil.
Further, described circuit board is PCB to the utility model, is erected at above the described coil of part.
Further, described coil is by being fixedly installed on the clip of the spring chuck activity on shell on shell for the utility model.
Further, described bar-shaped coil by being fixedly installed on shell has being fixed on shell of the holder activity of many rows of sockets to the utility model.
Further, the inductance value of described coil is 200mH to the utility model.
Further, the inductance value of described bar-shaped coil is 200mH to the utility model.
The beneficial effects of the utility model are mainly reflected in: by the transformation to antenna structure, make that originally magnetic field is more weak and zone line that is that can not be used effectively obtains good utilization, enhance the magnetic field intensity in region, improve the stability of information in reader reading electronic labels, increase reader and by the distance read between electronic tag.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of electronic bin RFID reader of the utility model antenna assembly.
Accompanying drawing illustrates:
1, coil 2, bar-shaped coil 3, first antenna 4, second antenna 5, circuit board 6, shell 7, spring chuck 8, holder.
Embodiment
The utility model discloses a kind of electronic bin RFID reader antenna assembly, is different from conditional electronic shelf RFID reader antenna.Below in conjunction with the accompanying drawing in the utility model embodiment, carry out clear, complete description to the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on embodiment of the present utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1, the utility model electronic bin RFID reader antenna assembly, comprise coil 1, antenna element and the circuit board 5 being connected antenna element by coil 1, coil 1 is positive circular coil, and positive circular hub of a spool position is provided with bar-shaped coil 2.Because existing reader antenna is square coil, when there being electric current to pass through, current conversion by coil is become electromagnetic wave, magnetic field is formed around coil, because the magnetic field produced by electric current is more weak in the intensity of square coil center, there will be cannot read, skip or need the phenomenon of repeatedly reading electronic labels information.The utility model main idea is to improve this phenomenon, and coil 1 is set to positive circular coil, and puts into bar-shaped coil 2 in the region that neutral magnetic field is more weak, thus strengthens the magnetic field intensity in whole region, effectively utilizes the reading range of finite region.
Particularly, the antenna element that the utility model embodiment provides is made up of the first interlaced antenna 3 and the second antenna 4, first antenna 3 and the second antenna 4 intersection location are positioned at the center of coil 1, this set-up mode is more conducive to the magnetic field intensity strengthening whole region, effectively utilizes the reading range of finite region.The PCB of circuit board 5 can be erected at above the described coil 1 of part, and by coil 1 by being fixedly installed on the clip of spring chuck 7 activity on shell 6 on shell 6, bar-shaped coil 2 is fixed on shell 6 by what be fixedly installed on holder 8 activity with many rows of sockets on shell 6, circuit board 5, coil 1, first antenna 3 and the second antenna 4 are by the cooperation with other fixtures, and fitting operation is convenient.
By above-mentioned setting of the present utility model, the inductance value of the coil 1 provided is set to 200mH, and the inductance value of bar-shaped coil 2 is 200mH, meets the requirement of the magnetic field intensity in region.During work, provide power supply by PCB for the first antenna 3 and the second antenna 4, become electromagnetic wave by coil 1 with the current conversion of bar-shaped coil 2, around coil, form stronger magnetic field.
Therefore, the utility model is by the transformation to antenna structure, make that originally magnetic field is more weak and zone line that is that can not be used effectively obtains good utilization, enhance the magnetic field intensity in region, improve the stability of information in reader reading electronic labels, increase reader and by the distance read between electronic tag.The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection range of the present utility model.
