Project background
With the rapid development of industry, industrial gases have been increasing in my country in recent years. However, there are many problems in the industrial gas retail/wholesale market. Industrial gases are flammable, explosive, and toxic. The rational use and management of industrial gas cylinders When it comes to the safety of life and property, improper handling will cause irreparable loss of life and property. The asset and safety issues of the bottled industrial gas market have attracted attention from relevant state departments.
In order to regulate the bottled market, my country has introduced a series of governance measures. Such as: steel cylinders are placed under the trusteeship of industrial gas companies, and they are uniformly inspected; increase the business access threshold to prevent unlicensed operations; strict workflow management, strengthen safety management, and so on. These measures have undoubtedly brought many benefits to regulating the market, but human factors still account for a large proportion of management.
How to use high-tech means to strengthen market safety management, market supply management, and reduce operating costs, so that various measures of the enterprise can be implemented truly and effectively, and to strengthen management is an urgent problem that needs to be solved.
The main problems in the circulation of industrial gas cylinders
For a long time, due to poor management of gas cylinders, loss of assets, outdated and inefficient distribution systems, high management costs, diversified property rights and difficult management, loopholes in the internal workflow of enterprises, illegal profit-making, and rampant black gas have become prominent problems in the bottled LPG market. .
Specifically, security and anti-counterfeiting issues, property loss issues and management issues:
1. Security and anti-counterfeiting issues:
1. At present, the gas cylinder filling industry generally has many problems such as unknown number of gas cylinders, unclear safety status, and unclear property rights information. Cylinders are circulating in the society and it is difficult to implement safety responsibilities, causing great safety hazards.
2. Regular safety inspections cannot be implemented, or gas cylinder users do not use gas cylinders in accordance with safety requirements or illegally modify or refurbish gas cylinders, resulting in a large number of gas cylinders on the market that have not been inspected normally, some of which may have been damaged to varying degrees , And cannot be identified and verified, and there are serious security risks.
3. Some units and individuals fill or pour gas between gas cylinders without permission. Some licensed gas cylinder filling units operate in violation of regulations, resulting in overfilling or wrong filling of gas cylinders, resulting in gas cylinders Accidents occurred in large numbers.
2. The loss of property and the problem of not being able to trace back:
1. The number of internal gas cylinders in the industrial gas filling unit is unknown, and it is difficult to distinguish the internal gas cylinders from the external gas cylinders, which may easily cause the loss of their own property.
3. Management efficiency and cost issues:
1. The dynamic management of gas cylinders entering and exiting the filling station, inspection station, and ventilation station cannot be realized, and the inventory status, production and sales status cannot be controlled and inquired in real time.
2. It is difficult to strictly control the circulation of gas cylinders between various operations within the enterprise, and gas cylinders that have exceeded their service life or have been judged to be scrapped may enter the filling and circulation links.
3. The historical records of the circulation process of gas cylinders inside and outside the enterprise cannot be inquired. The root cause of the problem cannot be determined when needed, and the hidden danger of accident cannot be discovered in time, which may produce more serious consequences.
4. Although existing enterprises have partially used modern management methods, there is a gap in the integration of information applications and actual needs.
Plan to achieve goals
Perform dynamic statistics and management of gas cylinders entering and exiting the filling station and the gas exchange station, and the industrial gas company can know the production and sales status of the gas at any time
Statistics and certification of internal gas cylinders of industrial gas companies to prevent confusion or loss, dynamic statistics and analysis of inventory cylinders and spare parts
The circulation of gas cylinders that have not passed the safety inspection can be restricted to ensure the safety of people’s lives and property.
It can confirm and manage the daily work of the industrial gas company, such as hazard source inspections, and the presence of personnel on duty.
Technical basis of the project
RFID (Radio Frequency ID) is a “radio frequency identification” technology, which is a non-contact automatic identification technology. The basic principle is to use radio frequency signals and their spatial coupling and transmission characteristics to realize automatic identification of stationary or moving objects to be identified, and to obtain related data for identification, statistics, and processing by the back-end system. At present, the frequency used by RFID spans multiple frequency bands such as low frequency (LF), high frequency (HF), ultra high frequency (UHF), and microwave.
RFID is an easy-to-control, simple, practical, and flexible application technology. Its unique advantages are beyond the reach of other identification technologies such as barcodes, magnetic cards, and IC cards. It can support both read-only work mode and read-write work mode without contact or aiming; reading can be completed in the moving process; supporting simultaneous reading and distributed data collection; storing information can be changed freely; working freely in each Under a harsh environment; a high degree of data integration can be carried out. In addition, because the technology is difficult to be counterfeited, RFID has a very high security protection capability. This technology can complete information input and processing without manual contact, optical visualization, and manual intervention, and the operation is fast and convenient.
RFID technology has matured and has been widely used worldwide. Typical application areas include: automatic identification and management of railway car number; automatic toll management of vehicle and road traffic; automatic identification and management of air storage containers; automatic identification, sorting, and transfer management of passenger air parcels; automatic control of product processing on production lines (Mainly used in the automated assembly line of large factories) and the automated management of logistics and warehousing, etc.
The variety of RFID products is abundant, the cost is continuously reduced, and the scale application industry is expanding. RFID technology developed earlier and faster abroad. There are more mature and advanced RFID systems in Europe, America and Japan. my country’s research on RFID technology has also developed rapidly, and market cultivation has begun to bear fruit.
RFID technology is relatively mature and has a good application foundation. The industrial gas cylinder and retail safety management system using RFID technology is safer, anti-counterfeiting, equipment easier to track and not lost, more efficient in operation, and more transparent and visible in management than traditional management methods. Some applications have been adopted by developed countries.
The overall design idea of the project
The basic goal of the gas cylinder and retail safety management system is to use advanced RFID technology to realize the full-range management of the filling and circulation process of gas cylinders. A special-shaped logo is fixedly installed on each cylinder of the gas company through a dedicated method. Electronic tags for life-time identification of gas cylinders. This system covers not only the management of gas cylinders entering and leaving filling stations, gas exchange stations, and distribution links, but also the status and behavior of each process in the filling and testing process of gas cylinders. Take control to ensure the safety of gas cylinder circulation, eliminate hidden dangers of accidents, maintain the personal and property safety of enterprise employees, and prevent illegal users from making illegal profits.
In addition, through portal technology and existing monitoring system for application integration.
Due to the application of middleware technology, the management system and the equipment are irrelevant. The system can easily replace the RFID electronic tags with barcodes, and the selected equipment supports the identification of RFID tags and barcodes at the same time.
The main content of the construction
1.Safety standards, testing standards, and application standards formulation
2. A data management center (platform system)
3. RFID middleware system development

Identification of industrial gas cylinders
The only corresponding to the identification electronic tag of the industrial gas cylinder is a group of data information closely related to the gas cylinder. The label can be flexibly installed during installation, so that it can be removed and reinstalled during detection. The data in the label is stored through encryption, so the reinstalled label can be guaranteed to be the label of the system.
Relevant enterprise operators can create files, edit and maintain this information through the system software. All operators and management personnel involved in the filling and circulation of gas cylinders can inquire part or all of the information through tag reading and writing equipment or management software according to their authority.
User identification and management
All users in the system are issued with readable and writable electronic tag user cards as the basis for identification and transaction. All users must first go to the company to go through the relevant procedures, receive the card and recharge. The delivery personnel send air to the door, confirm and deduct the corresponding amount of the user card through the tag handheld reading and writing device, and correspond the bottle number to it; or in the industrial gas station, the user can collect and return the gas bottle with the card, and the reading and writing device automatically judges the user card Whether it is legal and whether the number of gas cylinders on the card meets the requirements. When the conditions are met, the device automatically modifies the relevant information in the card, and the transaction data is immediately reported to the central management system.
Identification and management of operation personnel
Operators involved in system operations can be divided into the following categories:
1.Industrial gas station receiving and dispatching managers
2.Incoming management staff of filling station
3.Cylinder inspector
4.Cylinder filling personnel
5.Cylinder in and out management personnel
6.Equipment inspection personnel
7.System Information Manager
8.Decision-making or business management personnel
9.System management and maintenance personnel
For 1 to 6 types of personnel, the system will issue a unique user card for each employee, and the system will automatically determine its legality and authority when performing operations, and control its operations. After each operation is completed, the reading and writing device will report its identification code and operation information to the central management system of the system. So as to achieve real-time tracking and inspection of all personnel operations. For the 7th to 9th types of users, the system directly checks the identity and authority through the user name and user password.
The overall structure of the RFID industrial gas cylinder safety management system
Introduction to the process of filling and circulation of gas cylinders
The schematic diagram of the gas cylinder filling and circulation process under the management of the gas cylinder safety management system is shown in the figure below.
Schematic diagram of gas cylinder filling and circulation process of gas cylinder safety management system
When the user returns the bottle, the handheld device determines whether the gas cylinder is a legal gas cylinder. Under no abnormal conditions, modify the current circulation status of gas cylinders to “at gas station”. Then send it to the filling station. The operator in charge of entering the filling station uses a handheld device to register the received gas cylinder into the station. If there is a problem with the gas cylinder, the handheld device will start an alarm through text and sound, and the operator is asked to send the gas cylinder to the bottle inspection program. After the operator confirms, the cylinder is automatically set to the state to be inspected. In addition, if the incoming operator considers it necessary to inspect the steel cylinder based on actual judgment, the inspection can also be completed through the handheld device, and the steel cylinder will also be changed to a pending inspection state. If the cylinder enters the state to be inspected, the cylinder will be locked by the system before the registration of the inspection result is completed and the conclusion is qualified. If the steel cylinder is found at any link other than the bottle inspection, the handheld device will alarm and require the operator to deal with it. Cylinders that pass the bottle inspection and do not require bottle inspection can enter the filling process. For the sake of safety, the operator shall check and register with the handheld device again before filling to eliminate the steel cylinders that have entered the process due to the negligence of the previous operations. After the filling is completed, the operator uses the handheld device to register the filling result. If a problem is found, an alarm will be issued. When the filling weight does not meet the specified error requirements, it must be sent back to the filling process. The filled steel cylinders are then sent to the designated warehouse, and the warehouse management personnel use the handheld device for warehousing registration. The outbound registration is carried out before the cylinders are sent to the industrial gas station. Then, when the user provides a valid user card and the number of gas cylinders that can be collected meets the conditions, the user can withdraw the gas cylinders, and the handheld device is responsible for determining the user’s identity and registering the bottles.
User ventilation process
Uniformly replace the industrial gas supply certificate printed with RFID electronic tags or bar codes, and do a good job of registration, so that the industrial gas company can keep abreast of the user’s usage.
The user’s industrial gas supply certificate includes a ventilation ticket with an RFID electronic tag or bar code identification, which is scanned during a gas exchange and collected and managed by the industrial gas station staff to provide a basis for reimbursement with the industrial gas company.
When the user is ventilating, the staff of the supply station first scans the RFID electronic tag or bar code of the supply certificate with a handheld device to confirm the user’s identity.
Scan the empty bottles brought by users, dynamically add them to the database, record the empty bottles in storage, and then perform ventilation.
After the user’s changed industrial gas is scanned, it is also dynamically added to the library, so that the database has a record of the daily out of the library.
If the ventilation interval of a ventilation voucher is less than the set number of days, the system will automatically prompt and send out an alarm message to notify the staff to refuse to ventilate for it; at the same time, it also avoids the phenomenon of personal fraud by the staff of the industrial gas station.
Inspection process flow
The detection station mainly includes incineration, pressure measurement, leak detection, shot blasting, painting, etc. The high temperature of the incinerator will damage the label. In order to ensure the uniqueness of the gas cylinder information, remove the gas cylinder label before incineration. Each bottle is attached with an iron clip logo, so that the entire information chain is connected, and the label of the gas bottle is reinstalled, no matter how to ensure the uniqueness of the gas bottle information, and avoid potential safety hazards.
Equipment inspection process
By installing special electronic tags on important equipment, equipment inspection management can be realized, equipment maintenance personnel are urged to conduct regular inspections, and the system automatically records their inspection behavior. If equipment maintenance personnel are found to be dereliction of duty, the system immediately informs relevant management personnel.
From a functional point of view, the system can achieve the following functions:
1. The system has a data management center mainly for production, sales and storage of data, safety production and testing, supply chain data processing, and management of various business systems, and can alert illegal users and equipment. Use Portal technology to integrate the RFID system with the original video surveillance system. Achieve unified display.
2. Perform dynamic statistics and management of gas cylinders entering and exiting filling stations and ventilation stations. With the support of special software, the handheld device communicates with the server of the industrial gas cylinder safety management system of the industrial gas company in real time. The operator can obtain the current gas according to his authority. Some basic information of the bottle. When there are various problems with the gas bottle, the handheld device will send out an alarm through sound and text, and the operator is required to take necessary treatment. At the same time, the server management software of the industrial gas cylinder logistics safety management system automatically modifies the status of the gas cylinders and registers relevant information at the same time. Basic information such as the entry and exit time of the gas cylinder, the operator and the whereabouts of the gas cylinder.
3.Bottling plant (gas filling station) management
The gas cylinder from the gas exchange station is cleaned, the relevant information on the label on the gas cylinder is read through the RFID read-write device deployed in the cleaning line, and the relevant information is submitted to the production management system to enter the gas filling link; bottle inspection is carried out before filling If there is a problem, enter the inspection link, if it is normal, enter the filling line after passing the inspection; after filling, use RFID equipment to conduct corresponding inspections, and all information in the filling process is submitted to the production line management system, which is carried out by the production line management system Corresponding treatment saves labor and time.
Carry out strict process tracking management for the circulation of gas cylinders in the gas station, and provide basic management processes such as pre-filling management, post-filling management, bottle inspection management, and warehouse entry and exit management. Real-time registration and strict judgment of the dynamic information of the gas cylinders flowing through each link, to prevent unqualified gas cylinders from entering the filling link, filling unqualified gas cylinders into storage and other behaviors that violate the normal circulation safety requirements.
4.Bottling plant warehouse management
The gas cylinders in the warehouse are new bottles produced by the manufacturer and the bottles to be flushed returned by the user have a unique electronic tag to identify their identity and write corresponding information. The gas in the warehouse is read through the RFID read-write device deployed at the entrance. The number of cylinders and determine whether the cylinders are legal. Legal gas cylinders will enter the filling production line. If there is a problem with the gas cylinder, it will be sent to the bottle inspection program, the cylinder will be automatically set to the waiting state, and the gas cylinder will be locked by the system.
The filled steel cylinders are then sent to the warehouse, and the RFID equipment deployed on the production line is put into the warehouse for registration. When leaving the warehouse, use the RFID device to read the number of vehicles loaded, and write the corresponding information (such as delivery information) to load the vehicle, and automatically set the steel cylinder to the state of leaving the warehouse.
5.Distribution cylinder circulation management
Mainly for the management of distribution stations and ventilating stations. As the store sales method gradually becomes a large-scale distribution method and the service deepens, this link will be more on-site for gas delivery in the future.
When the user returns the bottle, the RFID device can determine whether the gas bottle is a legal gas bottle. Under no abnormal conditions, modify the current circulation status of the gas cylinder to “at a ventilation station”. Then send it to the filling station. If there is a problem with the gas cylinder, the equipment starts to alarm and ask the operator to send the gas cylinder to the bottle inspection program. After the operator confirms, the cylinder is automatically set to the state to be inspected. In addition, if the incoming operator considers it necessary to inspect the steel cylinder based on actual judgment, the inspection can also be completed through the handheld device, and the steel cylinder will also be changed to a pending inspection state. If the cylinder enters the state to be inspected, the cylinder will be locked by the system before the registration of the inspection result is completed and the conclusion is qualified. If the steel cylinder is found at any link other than the bottle inspection, the reading and writing equipment will alarm and require the operator to deal with it. Cylinders that pass the bottle inspection and do not require bottle inspection can enter the filling process. The desktop read-write device determines whether the user provides a valid user card and the user can withdraw the gas cylinder when the number of gas cylinders meets the conditions. The entry and exit of gas cylinders will be processed by reading and writing equipment at the exit and entrance, and data will be collected.
If the air is delivered to the door and arrive at the user, the delivery personnel use the RFID handheld device to operate the gas cylinder label and change the information. If the user has used the electronic tag certificate, the delivery person can directly use the handheld device to debit the user card, and the data will be submitted to the data center through wireless means. If the conditions are not met, the delivery person can return to the delivery station or the ventilation station. Upload the data in the handheld device to the data center through the computer.
6.Inspection station management
The detection station mainly includes incineration, pressure measurement, leak detection, shot blasting, painting, etc. The high temperature of the incinerator will cause the damage of the label. The important thing in this link is to ensure the uniqueness of the gas cylinder information. This link can be passed The association of the information chain re-installs the label on the gas cylinder.
7.Equipment inspection
By installing special electronic tags on important equipment, equipment inspection management can be realized, equipment maintenance personnel are urged to conduct regular inspections, and the system automatically records their inspection behavior. If equipment maintenance personnel are found to be dereliction of duty, the system immediately informs relevant management personnel.
