The automatic weighing and Filling machine collects the weight of the bucket identity data for the upper computer database to identify the bucket identity and size. It is composed of EPC passive chips, inductors, etc. The R signal from the reader is received through an external LC circuit, and then processed by the internal power circuit of the chip to provide power for the chip. Through the damping load inside the chip, The data in the on-chip EEPROM is read into the reader and the RF field is interrupted in a special way, allowing the reader to write the data into the on-chip EEPROM. The reader data is uploaded and entered into the server. An electronic tag is pasted on the appropriate part of the barrel. After the barrel is placed on the weighing platform, the RF card reader is aimed at the part of the electronic tag, and the card reader is started to read the ID code of the electronic tag. Then, the ID number of the bottle body is taken out from the card reader and uploaded to the single-chip microcomputer. The single-chip microcomputer then upload this data to the upper PC to enter the gas cylinder information database. The ID number is queried and compared in the database, and a code is returned to the single-chip microcomputer at the same time. On the one hand, the single-chip microcomputer returns a signal to the card reader to turn it off; on the other hand, it performs the relevant control operations of gas filling according to the program Settings.

The Liquid filling machine is based on the on-site management and control system of single-chip microcomputer, radio frequency card and network integration technology, which can effectively control the filling of materials in real time. Realize real-time detection of filling weight and real-time opening and closing of solenoid valves during the filling process, and upload data for effective computerized management. It mainly includes the 89C52 single-chip microcomputer control part, the radio frequency card reader part, the keyboard, the display control circuit part, the GM8125 serial port expansion circuit part, the LED display circuit part, the solenoid valve execution circuit part, and the upper PC database processing part. The RF card reader reads the electronic tag on the bucket body from the site and uplots the tag code to the upper PC for identity verification. If the identity is valid, it continues with the subsequent operation of opening and closing the solenoid valve and filling. During the filling process, the on-site effective weight data is uploaded to the upper computer in real time and classified and summarized together with the electronic tag code. The upper computer communicates with the server Send data to each filling station. For a large Filling system, the multiple filling and weighing data transmission lines of the filling station are connected in a serial bus manner, and data is uploaded or exchanged through a single line to reduce the laying of lines and achieve the purpose of resource conservation.
