The filling and unloading traceability information system for transportable pressure vessel scans electronic QR code through handheld explosion-proof terminal, carries out the inspection before, during and after the filling to form electronic records, and automatically obtains basic information of the transportable pressure vessel, such as ex-factory data, usage registration and inspection to determine whether the pressure vessel is qualified for filling and unloading, and to control the filling and unloading process. After the filling is completed, the filling amount, pressure, temperature, medium and other information are automatically collected and signed electronically, and the unloading data is uploaded after the unloading is completed. It meets the requirements of the Regulation for Production and Filling Licensing of Special Equipment (TSG 07-2019) and realizes the automatic collection of filling data.
