[0002] RFID technology: Radio Frequency Identification (RFID) is a type of automatic identification technology that uses wireless radio frequency to perform non-contact two-way data communication and read and write recording media (electronic tags or radio frequency cards) to achieve the purpose of identifying targets and exchanging data. It is considered to be one of the most promising information technologies in the 21st century.

[0003] Radio frequency identification technology uses radio waves to quickly exchange and store information without contact, combines wireless communication with data access technology, and then connects to the database system to achieve non-contact two-way communication, thereby achieving the purpose of identification and data exchange, connecting an extremely complex system in series.

The number and location information are sent to the terminal server by the MCU microcontroller through the 4G wireless communication module. The terminal server sends the gas cylinder information corresponding to the code to the MCU microcontroller through the 4G wireless communication module, and then broadcasts the information through the speech synthesis module, thereby realizing effective tracking of the gas cylinder location and information status.
