Description
Technical field
The utility model relates to the RFID label object thing in wireless radio-frequency field, is specially a kind of game money (Casino chip with RFID tag in UHF) of built-in uhf band RFID label.
Background technology
Game money (also can being called " chip " sometimes) replaces general currency to use in occasions such as the amusement game Rooms usually, and it is more big that its face amount amount of money can be 1 yuan, 5 yuan, 10 yuan, 20 yuan or other.In occasions such as the above-mentioned amusement game Room,, need especially to take precautions against to forge or the adulterium game money in order to ensure carrying out in order of recreation.In the prior art, can be applied to game money identification to RFID (Radio Frequency Identification) technology, RF label (tag) is set in game money, take precautions against the forgery or the adulterium of game money with this.As everyone knows, this RFID technology is by adhering to the RFID label that stores specified data and cooperate read write line (reader) to realize false proof on article.As shown in Figure 1, game money of the prior art 2 is built-in RFID label 1 can prevent the puppet/adulterium of game money, and can calculate the denomination of the game money 2 of random dispersion automatically.But the antenna of the RFID label of game money 2 inside only is formed on the face of substrate, when game money 2 is stacked together up and down (as shown in Figure 2), reaches 5 as long as stack quantity, and it is very low that the discrimination of rfid interrogator will become.The reason that discrimination reduces is that the distance between the upper and lower of the antenna of the RFID label 1 in the game money 2 that is stacked together becomes very little, causes forming mutual interference from the wireless signal that label antenna sends out.Game money 2 actual (real) thickness have only 3-5mm, if game money 2 is stacked neatly, 1 on built-in RFID label also have only 5mm apart from maximum between the upper and lower, thereby form serious interference and influence the anti-counterfeit recognition of game money and clearing automatically.
Up to the present, to confirming and prevent the puppet/adulterium of game money, the degree of accuracy that the raising system calculates the recreation Board Game coin number and the amount of money automatically also has a lot of restrictions.For example have the game money of built-in RFID label now, the antenna of its RFID label inside only is formed on the preceding one side of substrate, and the limitation of game money antenna structure makes system remain a lot of weak points to the correctness of information identification.
The utility model content
The utility model purpose is to overcome the deficiencies in the prior art, a kind of game money of built-in uhf band RFID label is provided, be embedded in the RFID label antenna circuit of game money inside by improvement: antenna circuit is distributed in the label substrate two sides, by applying identical copper sheet material in perforation and the aperture on the substrate to realize the connection between the antenna; The distinctive project organization of antenna circuit, each parameter of adjustable antenna improves tag sensitivity and decipherment distance with the coupling of the impedance phase between realization and the chip; The working frequency range of RFID label antenna is uhf band (908.5--914MHz), in transmitting at a high speed/and long range signals.
The utility model is achieved through the following technical solutions, a kind of game money of built-in uhf band RFID label, comprise RFID label and game money body two parts, the RFID label is embedded in the game money body, and both are one, it is characterized in that, described RFID label comprises the strip substrate, chip, first antenna, second antenna, chip places the substrate front and is connected with first antenna, formation constitutes and have the regulation shape with copper sheet first antenna is adhered in the front of described strip substrate, formation constitutes and have the regulation shape with copper sheet second antenna is adhered in its back, offer perforation on the substrate, first antenna, realize connecting by this perforation between second antenna.
According to described first antenna regulation shape, the first antenna conductor shape is class " it " font, promptly planar is repeatedly folding shape.
According to described second antenna regulation shape, second antenna conductor is covered in strip substrate back, and its form fit also is strip in the substrate back.
Preferably, described strip substrate rectangular shaped, corresponding second antenna pattern is matched with also rectangular shaped of substrate back.
Offer two perforation on the described substrate, two perforation are opened in the left and right sides of first antenna and second antenna conductor respectively, and form and the copper sheet of first, second antenna with material on the hole wall of footpath within it, interconnect to realize first, second antenna.
Offer two perforation on the described substrate, two perforation are opened in the left and right sides of first antenna and second antenna conductor respectively, metal closures is installed in the perforation interconnects to realize first, second antenna.
Preferably, described two perforation are the diagonal placement on substrate.
The working frequency range of described RFID label is the interval uhf band of 908.5--914MHz that is.
Described RFID label is embedded in the game money body, and both are one, its structure is specially: the RFID label is fixed in the central portion of game money body by the adhesion of strip substrate, form first in the injection of described central portion outside and spray thing, add to cover at described central portion and spray the formation second injection thing.
Described game money body, the outside of two sides central portion is respectively opened and has been cut cannelure before and after it, is forming first around the semi-finished product game money when spraying thing, make RFID label and this physical efficiency of game money firmer be adhered to one.
Described first antenna, second antenna offer reinforced hole on its circuit.Offer reinforced hole on the antenna circuit, when spraying for the second time, in order to increase the pull-out capacity between antenna circuit copper sheet and the substrate.
Preferably, described reinforced hole is provided with even number, and symmetry is positioned at by the chip both sides respectively.
Compared with prior art, the utlity model has following beneficial effect: at first, the utility model is distributed on the two sides, label substrate front and back it by the RFID label antenna that improvement is embedded in game money inside, and by the connection between the antenna on the two sides before and after the realization of the perforation on the substrate; Antenna has distinctive project organization, can make impedance phase coupling between itself and the chip by adjusting each parameter of antenna, so can improve tag sensitivity and decipherment distance greatly; In addition, the working frequency range of RFID label is uhf band (908.5--914MHz), in transmitting at a high speed/and long range signals.The game money of the built-in uhf band RFID of the utility model label, its antenna structure simplicity of design and ingenious, can realize the automatic calculating of game money denomination when being applied to the public place of entertainment and be convenient to taking out of/moving into of management game coin, and can prevent that game money is stolen, simultaneously can accurately recognize the identification chip true and false, thereby stop the puppet/adulterium of game money.
