Preferably, described travelling belt is paper tape.
Preferably, also comprise rfid interrogator and processor, described RFID antenna is connected with rfid interrogator, rfid interrogator is connected with processor, described rfid interrogator transmits to RFID radio-frequency card by RFID antenna, and described RFID radio-frequency card to receive after signal through RFID antenna feedback radio-frequency card identity information to processor.
The beneficial effects of the utility model are: the advantages such as RFID of the present utility model weak label screening plant has accurately and fast, sensitive, be applicable to the weak label screening of different size RFID tag, reduce production cost and improve the data that production technology provides necessity.This device can realize the screening of RFID weak label, and screening system speed is fast, per minutely can screen 120 labels, can continuous working.
Accompanying drawing explanation
Fig. 1 is the structural representation of the weak label screening plant of RFID of a kind of embodiment of the utility model.
Embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, the structural representation of the weak label screening plant of the RFID for a kind of embodiment of the utility model, the weak label screening plant of this RFID comprises a cabinet, the outer setting of described cabinet has a RFID antenna 3, a travelling belt 5 is provided with in described cabinet, the surface distributed of described travelling belt has RFID radio-frequency card 6, communicated by a passage 4 between described RFID antenna 3 and travelling belt 5, the side of described cabinet is provided with the first container 2 for holding travelling belt, and opposite side is provided with a second container 1 for driving travelling belt to reclaim.Hold the travelling belt not carrying out screening in first container, in second container, reclaim the travelling belt through screening.
The passage 4 of the weak label screening plant of the utility model RFID is taper, and described passage is less than the port near RFID antenna near the port of travelling belt, and described RFID antenna receives only the signal of one of them the RFID radio-frequency card on travelling belt at any one time.Passage of the present utility model makes to state RFID antenna can only receive RFID radio-frequency card signal a moment, avoids the problem of train of signal number.
Second container 2 of the present utility model comprises a box, and be provided with one in described box for being wound around the rotating shaft of conveying belt, described rotating shaft is connected with the output shaft of a motor.Conveying belt of the present utility model drives the pivot in box via motor, thus drives the movement of travelling belt, reaches travelling belt and drives the RFID radio-frequency card arranged on a moving belt to move in cabinet, meet the continuous working of screening label.
Travelling belt of the present utility model is paper tape, and RFID radio-frequency card is distributed on paper tape.Preferably, the part that travelling belt of the present utility model is positioned at cabinet is again arranged on cylinder, because cylinder can rotate, makes the friction between travelling belt and cylinder less, decreases friction.
The weak label screening plant of RFID of the present utility model also comprises rfid interrogator and processor, described RFID antenna is connected with rfid interrogator, rfid interrogator is connected with processor, described rfid interrogator transmits to RFID radio-frequency card by RFID antenna, described RFID radio-frequency card to receive after signal through RFID antenna feedback radio-frequency card identity information to processor, and processor carries out respective handling according to feedback information.
Signal control device is provided with in the weak label screening plant of RFID of the present utility model, when RFID antenna transmits ripple, can the energy that receives of control RFID radio-frequency card radio frequency signal wave limit, screening parameter scope: TxPower:5 ~ 32.5dbm, RxSensitivity:-100 ~-70dbm, by control be arranged in cabinet surrounding in different antennae emissive power, calculate multiple antennas in multiple latitude determination situation, the average < of multi-dimensional signal intensity-72dbm, weak label can be regarded as, thus accurately can judge whether described RFID radio-frequency card is weak label.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
