Weighing and Filling machine for the barrel identity data weight collection for the upper computer database for barrel identity and regulation identification, based on EPC passive chip inductor coil and other components, through the external LC circuit to receive the R signal from the reader, through the chip internal power circuit processing to provide power for the chip, through the chip internal damping load, the data in the on-chip EEPROM is read into the reader, and in a special The data in the on-chip EEPROM is read into the reader-writer, and the RF field is interrupted in a special way, so that the reader-writer can write the data into the on-chip EEPROM. The reader-writer data is uploaded to the recording server. The appropriate part of the barrel is pasted with an electronic label, when the barrel is put on the weighing platform, the RF reader will be aligned with the electronic label part, start the reader to read the ID code of the electronic label, and then take out the ID number of the bottle from the reader and upload it to the microcontroller, the microcontroller will then upload the data to the upper PC to enter into the database of gas cylinder information. the ID number will be queried and compared in the database, and at the same time, a code will be returned to the microcontroller. On the one hand, the microcontroller returns a signal to the reader to close the reader, and on the other hand, the microcontroller carries out the relevant control operations of gas filling according to the program settings.

Liquid filling machine based on single-chip computer, radio frequency card and network integration technology on-site management, control system, can be effective real-time control of material filling. Realize the filling weight of real-time detection and filling process solenoid valve real-time open and close, data upload for effective microcomputerized management. Mainly includes 89C52 microcontroller control part, RF card reader part, keyboard, display control circuit part, GM8125 serial expansion circuit part, LED display circuit part, solenoid valve implementation circuit part, the upper PC database processing part. RF reader from the scene to read the barrel of the electronic label will be uploaded to the upper PC label code identity determination, if the identity of the lawful, it is Continue to carry out the following switch solenoid valve and filling work, in the filling process on-site effective weight data real-time uploaded to the upper computer, with the electronic label code together for classification and summary, the upper computer and the server for communication, send the filling site data. For a large Filling system is the filling station of multiple filling weighing data transmission line to serial bus way to connect up to a single line upload or exchange data, reduce the line laying, in order to achieve the purpose of saving resources.
