RFID electronic tags carry out systematic management of dangerous goods gas cylinders

Most dangerous goods gas cylinders have the characteristics of being excessive in number and widely distributed, and the entry threshold for gas cylinder filling operations is low and safety management measures are weak, which can easily cause accidents with extremely serious consequences. Before systematic information management was adopted, dangerous goods gas cylinders used a management plan with etched numbers, and the qualification marks were made of paper. Bottle collection, filling, distribution, and inspection information were all collected manually, and the accuracy of entry was poor; and this This management method cannot achieve dynamic tracking of gas cylinder safety management, and lacks traceability of the quality of the filled gas. Using RFID electronic tags as the unique management identifier of gas cylinders can realize tracking and management of gas cylinders throughout their life cycle.

       The gas cylinder application management system consists of four layers: RFID electronic tags, RFID identification terminals, RFID data collection and database management.

        After the RFID electronic tag is initialized, the unique identification code of the tag chip is correspondingly bound to the gas bottle usage registration code and gas bottle etching number burned on the surface of the label, and written into the electronic tag. At the same time, a gas cylinder basic information database is established, and its data Items meet the requirements for gas cylinder management. Use the handheld reading and writing device to write the basic information of the gas cylinder that needs to be recorded in the label into the electronic label affixed to the bottle body, and transmit the ID code of the label to the backend together with the basic information of the gas cylinder recorded in the label. In the enterprise database, the label etching number, label ID code, gas cylinder usage registration code and basic gas cylinder information associated with them are generated in the background database.

       When the gas cylinder is recycled, the RFID Reader is used to read the basic information Stored in the RFID electronic tag, determine the legality of the gas cylinder, write the recycling mark and date into the electronic tag, and generate a recycling record of the gas cylinder in the reader. And transmitted to the enterprise's backend database, the data content includes the gas bottle etching number, label serial number, gas medium, user information, recycling date, recycling operator number, etc. The backend system can automatically generate a gas cylinder recycling record report.

       Before filling the gas cylinder, use an RFID reader to read the information in the electronic tag to determine whether the gas cylinder is qualified, write the results of the pre-filling inspection into the electronic tag, generate a pre-filling inspection record in the reader, and transmit it to The background also generates pre-filling inspection record reports. The above steps must be carried out during and after filling, and a record of the entire filling process must be generated.

       When the gas cylinder is delivered, the historical delivery record is updated through the reader/writer, the delivery site or the user's direct code is entered and written into the electronic label. The gas cylinder delivery record is generated in the reader/writer and transmitted to the enterprise's backend database to generate reports.

       The gas cylinder filling unit will send the gas cylinders that are close to the inspection date identified by the reader to the inspection station. The inspection station will inspect the gas cylinders, write the results into the label, and send the inspection information to the inspection agency through network transmission. , the inspection station feeds back to the filling company. A qualified inspection report will be generated for the gas cylinders that pass the inspection, and a scrapping notice will be generated for the unqualified gas cylinders.

       The application standardization of gas cylinder electronic labels needs to follow the coding rules specified in the TS 4501-2005 technical document of the General Administration of Quality Supervision, Inspection and Quarantine, and apply for the gas cylinder electronic label object identifier from the domestic OID registration agency. Due to the large climate difference between the north and south of my country, RFID electronic tags are generally required to have certain adaptability to the lowest temperature in the northern areas where they are resident. At the same time, gas bottle electronic tags also need to have the characteristics of anti-metal shielding and control of frequency drift. The requirements for readers and writers are higher. They need to adapt to specific climatic environments and have extremely high explosion-proof requirements. At the same time, they must be free from shielding interference, have sensitive communication functions, and have high reliability.

       The IFAST explosion-proof handheld terminal has an explosion-proof level of Ex ib IIC T4 Gb. The device has a 5-inch high-definition and bright 720P display screen to meet the requirements of outdoor operations; it supports all network standards; the flexible circuit design provides customized, Customized service; the device integrates multiple data collection functions and wireless communication, with reliable performance and simple operation; IP65 protection level, achieving a high degree of unity of performance and durability; ergonomic design and user-friendly interface, etc. The multi-faceted innovative design can maximize work productivity; explosion-proof products are widely used in the petroleum and petrochemical industry and are one of the first choices for gas cylinder management application equipment.

       Short strip ultra-high frequency RFID electronic tags are assembled from high-temperature resistant Engineering plastics and are UHF band passive radio frequency tag products. The product has an interface that is fully compatible with UHF EPC G2 standard, non-contact data transmission and energy supply, high-speed data transmission rate, 512bit user memory storage space, 96bit EPC space, 64bit tag identifier, 32bit access password, 32bit self-destruct password, applicable application management of the system.

       IFAST has implemented a unified safety management information system for taxi gas cylinders. Including providing integrated software and hardware services such as electronic labels, identification terminals, and supervision information service platform construction, informatizing and tracing the complete life process of gas cylinders, establishing a big data analysis model for gas cylinder safety data, and seizing the risks of gas cylinder safety The key links of manufacturing, filling control, regular inspection, safe use, and scrap elimination can fundamentally reduce the probability of gas cylinder accidents and ensure the safety of gas cylinders to the maximum extent.
