With the improvement of people's living standards, the number of liquefied petroleum gas cylinders has also increased dramatically. Liquefied petroleum gas has many problems, such as wide use, large quantity, large liquidity, harsh use environment and lagging regulatory measures, which cause huge safety hazards.
Under this background, it is urgent to strengthen the government safety supervision of liquefied petroleum gas cylinders, implement the policy of cylinder construction, fixed-point filling, and regular inspection, and establish a networked dynamic gas cylinder safety management system.
RFID technology has played a key role in this management system. Through RFID technology, the identity of the gas cylinder can be quickly and accurately identified, the production efficiency can be improved, and the gas cylinder to be inspected can be prevented from flowing into the production process, resulting in quality hazards.
Specific process:
1. First, establish a computer resume file database of gas cylinders.
2. Use the RFID handheld reader to read the electronic label of the gas cylinder, and the on-site operation data of the process of sending and receiving the gas cylinder, pre-charge inspection, filling and filling, re-inspection, and periodic inspection are collected and registered.
3. Alarms and prompts for abnormal and bad cylinders.
 

RFID technology can effectively integrate the daily management activities of medical assets with the medical asset management system, so as to achieve the real-time synchronization of physical information and system information, and quickly find various medical assets in an emergency.
Each medical asset is attached with an electronic tag with a unique ID number. When the item with the electronic tag enters the identification area of the reader, the information that the electronic tag keeps issuing will be received by the long distance RFID reader. The writer passes the information to the computer, and the computer system performs corresponding format conversion, filtering, and subsequent statistical processing to determine whether the item should be stored here and other related information.
The outer packaging of the drug is affixed with a barcode, and the drug and barcode information is registered in the background. When the nurse distributes the medicine to the patient, the scanner scans the barcode of the medicine, and then checks the patient's wrist label information, and distributes the medicine to the patient after confirming that the photos, names, and medical names in the hand are consistent. At the same time, the handheld terminal wirelessly transmits the distributed information to the background management center for information storage.
The temperature sensor can be used to continuously monitor the internal temperature for 24 hours to prevent unnecessary loss due to temperature changes. The temperature tag transmits the temperature change signal to the reader, and the reader transmits the signal to the background operating system. When the temperature exceeds the acceptable range, an audible and visual alarm is issued, and the detailed alarm freezer or thermostat location, storage items, etc. are clearly indicated. information.

In 2002, Metro announced the "Future Store" program, which announced the adoption of RFID technology throughout its supply chain. The program has attracted more than 50 partner companies to jointly develop and test applications for IoT RFID technology, covering all aspects of the retail supply chain, including inventory, transportation, logistics, warehousing, and even the retail in-store customer buying experience.
Metro has built a comprehensive tracking system for RFID pallets and deployed multiple RFID applications. Pallet tracking is the basis of the distribution center RFID system. More than 100 Metro's suppliers use RFID tags in their warehouses, logistics, distribution containers and pallets.
A fixed RFID reader device is installed on the warehouse door. When the pallet passes through the warehouse door, the data on the container label can be automatically identified, collected, and transmitted to the enterprise system through automatic finishing; the system will provide this information.
