To sum up, the working principle of the entrance guard all-purpose card management system based on RFID for reading an RFID information card through the RFID card reader 7 is as follows: the driver drives the vehicle to the electric barrier gate 6, the RFID information card is close to the detection sensor 94 on the front side of the first sealing plate 92, at this time, the detection sensor 94 on the front side of the first sealing plate 92 sends a signal to the rotating equipment, the timing device 953 starts timing, the rotating equipment drives the shaft body to enable the driving gear 966 to rotate, the driving gear 966 is matched with the rack, the first two sealing plates 92 further move away from each other to enter the second extending port 83, meanwhile, the pull rope 962 is wound when the shaft body rotates, the pull rope 962 drives the connecting block 964 to enable the receiving plate 951 to drive the RFID card reading area 72 to move outwards, at this time, the driver drives the RFID card reading area 72 on the outer side of the RFID card reader 7 to read a card, and the corresponding electric barrier gate 6 is effectively clamped, the rotating equipment is driven to reversely rotate after the timing device 953 reaches the designated time, the first sealing plates 92 are driven to mutually close to move until the opposite sides of the first sealing plates 92 are attached, and the follower shaft 965 reversely rotates under the action of the elastic reset piece to wind the pull rope 962 when the rotating equipment reversely rotates, so that the RFID card reader 7 enters the protecting shell 91; when the driver drives the vehicle to be too high and can not drive the detection sensor 94 at the position corresponding to the first sealing plate 92 of the RFID information card, the detection sensor 94 at the top of the second sealing plate 93 can be corresponding to the RFID information card, the detection sensor 94 controls the bidirectional telescopic device 97 and the driving device 954 to be opened, meanwhile, the timing device 953 starts timing, the bidirectional telescopic device 97 enables the two groups of the second sealing plates 93 to be closed after being far away from each other into the first extending opening 82, the driving device 954 drives the studs to enable the movable plate 952 to be upwards until the sliding blocks on one side of the movable plate 952 contact the closing part 956, at the moment, the driving device 954 is closed, the movable plate 952 upwards drives the RFID card reader 7 to upwards move the protective shell 91, at the moment, the driver can read the RFID information card corresponding to the RFID card reading area 72 at the top of the RFID card reader 7, the effective card is controlled to lift the railing, after the timing device 953 reaches the designated time, the driving device 954 is driven to reversely rotate the studs, the movable plate 952 is driven to reset, and the bidirectional telescopic device 97 is controlled to drive the two groups of the studs to reset after the movable plate 952 is reset to be contacted with the reset part 955.
Although embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the application, the scope of which is defined in the appended claims and their equivalents.
