Specifically, the working principle of the electronic tag identification, positioning, reading and writing device of this embodiment is as follows:

The steel cylinder 18 travels on the first-class assembly line. When the steel cylinder 18 reaches the vicinity of the RFID antenna 15 and touches the interlock switch 1, it drives the second cylinder 10 connected to the proximity switch 3, and the proximity switch 3 performs gas-electric conversion through the input and output control card 4. Send an input signal to the host computer 17, and the host computer 17 starts the card reader 19 to start working. At the same time, the upper computer 17 sends out an output signal, which drives the third cylinder 11 to push out the pulley arm 12 after the electrical conversion through the solenoid valve 8, and the driving wheel 7 and the driven wheel 6 hug the steel cylinder 18 together, and the upper computer 17 is electrically converted through the electromagnetic valve 8 Then drive the second cylinder 10 to jack up the lifting platform 5 synchronously, lift the steel cylinder slightly, leave the traveling chain 20 of the assembly line, so that the steel cylinder 18 can stay near the RFID antenna 15, and drive the steel cylinder 18 to rotate through the driving wheel 7 . When the electronic tag 16 of the steel cylinder turns to the reading and writing range of the RFID antenna 15, the card reader 19 can read the UID (unique identifier) of the electronic tag 16, and at this time, the host computer 17 stops by the stepper motor 13 The driving wheel 7 rotates, and reads the content of the electronic tag and compares the data. In normal use, there are generally two types of liquefied petroleum gas cylinders with different specifications. In view of this situation, the movable shaft 14 can adjust the position of the RFID antenna up and down and forward and backward according to different steel cylinders, so that the identification and reading and writing efficiency of the RFID antenna 15 to the electronic tag 16 is higher. During the operation, there will be the following four situations for the identification and reading and writing of the electronic tag 16:

(1) When the data block of the electronic tag contains information beyond the filling period, the data block is not written, and the operation of putting the bottle is directly performed to reset the steel cylinder.

(2) When the data block of the electronic tag contains information that has not exceeded the filling period, write the data block, for example, write the current date into the electronic tag, and then perform the operation of putting the bottle to reset the steel cylinder .

(3) When the data block of the electronic tag is not read, and only the UID of the electronic tag is read, the host computer sequentially passes through the input and output control card, the motor driver and the stepper motor to drive the The driving wheel is reversed by 10 degrees, and the data block of the electronic tag is read again while the driving wheel pauses for 0.5 seconds. If it is read, the data block is written. If the electronic tag is not read again For the data block of the tag, reverse the driving wheel 10 degrees again, and the motor stops again for 0.5 seconds to read the data block of the electronic tag. If it is read, write the data block. If not, then Data blocks are not written. What is used here is the small step error of the stepping motor, and the characteristics of fast forward and reverse rotation can be used to realize the precise control of the positioning of the electronic label on the cylinder. When both operations fail, it is judged that the electronic label on the current cylinder is damaged, and the operation of releasing the cylinder is performed to reset the cylinder.

(4) When the data block of the electronic tag is not read, and the UID of the electronic tag is not read, then the data block is not written, and the electronic tag on the steel cylinder is judged to be damaged or falls off, and the bottle is placed The operation resets the cylinder.

In the bottle releasing operation, the upper computer 17 issues a bottle releasing command after comparing the data blocks of the electronic label, and drives the third cylinder 11 through the electro-electric conversion of the solenoid valve to retract the driven wheel, and the lifting platform passes through the second cylinder 10 is also retracted, and the steel cylinder is put back into the traveling chain of the assembly line to allow the steel cylinder to pass directly.
