With the development of science and technology, the Internet of Things technology has achieved rapid development in recent years. At present, the Internet of Things technology is widely used in all walks of life, and in the gas industry, the Internet of Things technology is gradually being applied. In the gas industry, the application of Internet of Things technology mainly includes the application of RFID radio frequency identification in gas security inspection management, equipment management, and gas cylinder management; at the same time, it is based on sensor technology in smart gas meters, confined space monitoring, valve well monitoring, The application of pipelines to prevent third-party damage. This article starts from a news report “Information supervision of bottled gas in Jinyun, Lishui, Zhejiang” as an introduction. It briefly introduces the application of Internet of Things RFID technology in gas cylinder management to escort gas safety.
Third, the Internet of Things RFID technology boosts the safety management of gas cylinders
1. Internet of Things
Internet of Things (Internet of Things) is the use of radio frequency identification (RFID) (RFID+Internet), infrared sensors, global positioning systems, laser scanners, gas sensors and other information sensing equipment, according to the agreed agreement, to connect any item to the Internet Connected for information exchange and communication to realize intelligent identification, positioning, tracking, monitoring and management of a network. The Internet of Things technology is mainly used in the following two aspects:
(1) Identify objects through RFID technology to realize intelligent identification and correlation functions. RFID technology integrates radio frequency technology and embedded technology as an integrated technology. RFID has broad application prospects in automatic identification and item logistics management.
(2) Realize the positioning, tracking, monitoring and management of objects through sensor technology.
At present, the Internet of Things is widely used in smart transportation, smart city, gas safety, environmental protection, government work, public safety, safe home, smart fire protection, industrial monitoring, environmental monitoring, street lighting control, landscape lighting control, building lighting control, square lighting Management and control, elderly care, personal health, flower cultivation, water system monitoring, food traceability, enemy investigation and intelligence collection and other fields.
2. The application of Internet of Things RFID technology in gas cylinder management
In our country, bottled gas is still used in large quantities in the fringe areas of urban and rural areas, the catering industry, and the vast towns and rural areas where natural gas has not yet been popularized. From the analysis of recent gas safety accidents, a large part of gas safety accidents are caused by bottled gas. Therefore, with the advantages of Internet of Things RFID technology, the application of RFID technology in the management of gas cylinders enables the intelligent management of gas cylinders. , To reduce the occurrence of gas safety accidents.
For example, according to a report from China Gas Network: Recently, the bottled gas safety management information system in Jinyun County, Lishui, Zhejiang was officially launched. Through the data platform, the registration of gas cylinders, regular inspections of gas cylinders, gas cylinder inspection data, gas cylinder safety data analysis and analysis can be realized. Electronic networking of statistical work. In addition, all filling equipment will also be equipped with intelligent interlocking devices. “Unlicensed black users” will no longer be able to refill. If gas cylinders wearing a QR code are not inspected after the expiry date, the filling equipment will give an alarm and refuse to refill. In the future, bottled gas users only need to scan the QR code, and basic information such as the filling status, useful life, and cylinder defects of each gas cylinder can be seen at a glance. In the next step, the construction of monitoring video networking for gas operating companies will be carried out, and the identity of personnel entering the station, vehicles, electronic tags on gas cylinders, implementation of real-name registration of bottled gas sales, gas cylinder delivery personnel, and production areas that violate safety production regulations Supervise bad behavior.
Therefore, the application of IoT RFID technology in the management of gas cylinders is mainly to install a chip embedded with RFID technology on the cylinder, and to embed a smart angle valve with a limited charge control device, and be equipped with a smart angle valve inflating gun , Mobile distribution handheld gun, electronic canning scale, Internet of Things management system and other software and hardware systems, forming a complete set of gas cylinder charging system based on RFID technology. As shown in Figure 3-1:
Figure 3-1 Cylinder safety IoT management system
The application of the Internet of Things RFID technology in the management of gas cylinders is conducive to the safety monitoring of gas companies and regulatory authorities on the entire life cycle of the filling, use, logistics, inspection, and elimination of gas cylinders in gas companies, and it also It is convenient for enterprises to perform statistics and analysis of the entire loading operation, maintenance of customers, and monitoring of self-use gas cylinders. The application of Internet of Things RFID technology in gas cylinder management can meet the following safety requirements and process monitoring.
(1) Process safety monitoring of the filling and use of steel cylinders
1) It can be canned automatically. The smart angle valve based on the RFID technology of the Internet of Things can identify whether it is the company’s smart gun. If it is not, the valve is not opened for filling operations. In this way, the filling of non-owned bottles can be well controlled and safety accidents can be prevented.
2) The overfilled volume of the gas cylinder can be automatically identified. Automatically identify the amount of gas required for the cylinder to prevent the occurrence of overfilling accidents.
3) It can prevent cross inflation. Because the number of RFID cylinders of each company is different, it can prevent fork inflation between different companies. Monitor the process safety monitoring of their own bottles.
4) Put an end to illegal gas pouring. Since gas cylinders can only be inflated in one company, and each inflation system has a record, gas companies can easily find out if gas is poured.
5) To prevent refilling of unchecked cylinders, the security check record is linked to the RFID tag. Each time the cylinder is filled, the security check record of the cylinder will be queried. For those without security check or failing the security check, the system will refuse to refill.
6) If you refuse to refill the scrap steel cylinder, the scrap steel cylinder will be displayed as scrap in the system, and there is no security inspection mark, and the refilling will be refused.
(2) Monitoring of cylinder verification
It can automatically determine the safety inspection status of the cylinder, and feedback the verification status of the cylinder in real time. During security check, RFID technology can be used to identify steel cylinders and understand the history of security checks of steel cylinders.
(3) To facilitate the gas company’s overall process statistics, safety monitoring and analysis, and customer maintenance
1) Automatically count the filling workload: Since the filling gun is controlled by a computer and connected to the gas company through the network, the filling volume is synchronized to the company’s database.
2) The cylinder filling records are reported automatically. The gas filling gun is connected to the gas company central server through the network, and the filling amount will be transmitted to the gas company server in real time, which is convenient for the gas company to count and monitor.
3) Automatic identification of customers: RFID as a unique identification can use the management system to identify customers.
4) Put an end to the loss of steel cylinders: Since it is impossible to go to other companies to inflate, put an end to the loss of steel cylinders.
5) Prevent customer churn: Since it is impossible to go to other companies to inflate, the churn of all customers can basically be eliminated.
Four, summary
Through the application of Internet of Things RFID technology in gas cylinder management, the “full life cycle” and “full process” of gas cylinders can be tracked and managed, and the gas cylinder information, distribution process information and filling record information of gas users can be controlled in real time. It is of great significance for the safety management and monitoring of the entire life cycle of gas cylinders from filling, use, and inspection. At the same time, it is of great significance to further prevent the occurrence of gas safety accidents. In short, with the development of the current Internet of Things technology, the RFID technology based on the Internet of Things will be increasingly popularized and used in all aspects of gas safety to protect gas safety and reduce and prevent the occurrence of gas safety accidents.
