1. System background
At present, the safety management of the gas cylinder industry is rather chaotic. There are many problems such as unclear number of gas cylinders, unclear safety status, and unclear property rights information. Gas cylinders are circulating in the society and it is difficult to implement safety responsibilities, causing great safety hazards.
Adopt RFID wireless radio frequency technology, use UHF electronic tags to give each gas cylinder a unique identity authentication, establish a gas cylinder traceability management system, realize the informationization and automation of gas cylinder safety management, and improve the overall control level and efficiency of gas cylinder management .
Second, the work process
1. Give each gas cylinder a unique identification code, and install its carrier radio frequency electronic tag on the gas cylinder. At the same time, the radio frequency electronic tag is numbered and registered. The filling unit establishes a computer resume file for all the gas cylinders of the unit.
2. Use passiveRFIDHand-held mobile readers collect and monitor the information of gas cylinders at different gas cylinder application sites. The RFID handheld reader can automatically read electronic information within the effective monitoring range, without the need to find the gas cylinders to be detected one by one.
3. Passive RFID fixed electronic base stations are used to collect and monitor information on gas cylinders at the storage site, and manage the entry and exit of gas cylinders. The passive RFID fixed electronic base station and the computer are connected through a data line to automatically collect gas cylinder information.
4. Install LAN wireless routers in the gas cylinder storage site and in the land area to form a wireless data transmission link with passive RFID mobile handheld readers and computers to automatically transmit measurement and control data. Passive RFID fixed electronic base stations carry out information collection and monitoring 24 hours a day, and discover and record the entry and exit of gas cylinders.
5. Manual intervention is required for the inventory of gas cylinders. When inventorying or spot-checking the storage and use of gas cylinders, the management personnel shall visit the site where the gas cylinders are in use within the specified time. During the visit, the system automatically completes the detection and transmits data to the computer.
3. System advantages
1. Solved the problem of unknown number of gas cylinders;
2. Realize the computer dynamic management of the safety status of gas cylinders in the jurisdiction;
3. Eliminate the illegal phenomenon of filling units that have not been registered or the property rights are not in the unit;
4. Improve work efficiency, greatly reduce labor intensity, and improve the management level of filling units;
5. Ensure the uniqueness of gas cylinder information, strengthen the safety and anti-counterfeiting supervision and safety management of LPG cylinders, strictly implement the policies of gas cylinder archives, fixed-point filling, regular inspection, and expired scrapping to ensure the safety of people’s lives and properties;
6. Through the real-time collection of gas cylinder status information, the status and flow direction of the gas cylinder can be tracked, and the loss of property can be avoided.
