- Use and development of lead seals for power metering equipment
В последние годы, некоторые преступники произвольно повредили и скорректировали оборудование для учета электроэнергии, чтобы достичь цели уклонения от счетов за электричество, причиной больших потерь для страны и отделов электроснабжения. Согласно статистике Государственного департамента электроэнергетики, Китай проигрывает 20 billion Yuan（2.5 billion USD） in electricity theft every year. Because traditional signatures do not have the function of counterfeiting and are easy to prevent, the phenomenon of electricity theft is becoming more and more serious. The most common and simple method of electricity theft is It is the destruction and forgery of the seal of the electric energy meter, causing the meter to be dialed, wrong wiring, disconnection, и т.д., which cannot be measured correctly, the efficiency of the enterprise is greatly infringed, and the national property suffers a huge loss. Поэтому, how to use high-tech means to improve the management level, prevent, detect, and plug the loopholes of stealing electricity in time, and restore economic losses, is an increasingly urgent need for the power sector. RFID electronic seal electronic tags show their strengths in various instruments!
The intelligent seal management system based on RFID technology can solve all the above problems! The application of RFID electronic seal in the electricity meter anti-theft/gas meter/water meter/anti-counterfeiting.
System introduction
Intelligent seal management system, which has functions of anti-theft, anti-tampering of data, inspection and supervision, и т.д.. The following is the introduction of the system.
2.1 System advantages:
- Provide advanced anti-counterfeiting methods to prevent outsiders from forging seals.
The shape cannot be imitated.
The combination of RFID technology and two-dimensional code has higher anti-counterfeiting performance.
The old-fashioned lead seal only relies on the steel seal on the pliers in the hands of the operator to distinguish between authenticity and cheating. The product has a systematic digital code. The product and the code correspond one-to-one without duplication, so that the system can be managed by a computer. The use of each seal can be checked on the computer, thereby eliminating the possibility of collusion between internal and external electricity theft at the source.
The electronic seal adopts a one-time blockade that cannot be opened without damage, which effectively prevents the old-fashioned lead seal from recovering after being pried.
- Provide reliable and effective inspection methods to minimize inspection errors caused by subjective factors.
Герметизация: Use steel wire (or sealing line) to tighten, and it can only be tightened and cannot be pulled out.
Unpacking: It needs to be cut with a special tool for one-time use. A non-contact identification chip with a unique ID number is encapsulated inside the seal, which can ensure the uniqueness and non-explicability of the seal number. The seal is printed with a unique code independently defined by the company, which is highly secure.
Герметизация: RFID считыватель, non-contact one-key sealing, simple and fast, at the same time the data of the electronic seal can be collected into the handheld inspection device, and then sent back to the host database system for inspection and analysis of whether the data is legal.
- Provide scientific management methods to achieve effective management of the seal itself and internal staff.
Helped the electric power department to achieve a fully closed-loop management process for power metering equipment.
The three-layer anti-counterfeiting design ensures that the seal will not be counterfeited and management confusion.
For situations that may occur in the application, such as loss, damage, и т.д., a freezing mechanism is designed to unfreeze the seal after it is found to avoid confusion in the application of the seal without wasting.
The whole process of seal tracking is designed to facilitate tracing and finding the cause of the problem when damage is found.
The entire business process of the seal is managed in a refined manner. Each operational business process from warehousing, шифрование, disbursement, sealing, inspection, unsealing, review, and scrapping has clear operation records, making the use of seals more scientific and reasonable.
2.2 System composition: The system consists of the following parts. As shown below:
The system software platform is divided into stand-alone version and online version. The online version is installed in the marketing network. From the city company level to each county company, and each power supply station can open and enter the system; it can exchange data with the power marketing system. (But the power marketing system must provide a data exchange interface) The following is a flowchart of the entire program.
Три, system function
It realizes the whole-process personalized and quantitative management of power metering equipment, and helps the power department to achieve a fully closed-loop management process for power metering equipment.
It realizes the whole process automation of electricity installation, meter reading, electricity inspection, and point inspection, и т.д., и сбор информации, ensuring the reliability of electricity inspection, improving work efficiency, and reducing errors caused by human factors.
It realizes the standardization and supervision of the work of internal personnel, facilitates the evaluation and summary of the work done, and provides a basis for clarifying responsibilities and improving work.
Realize the data sharing with the MIS system, can be compatible with the existing meter reading process, and adopt a distributed multi-layer application system based on the B/S structure to ensure the safety, надежность, efficiency and easy maintenance of the system. It can realize a smooth transition from the existing operation process.
- System function and benefit analysis
Combining the implementation and application of electronic seal and intelligent seal management system will bring many benefits to our daily work. The main benefits are reflected in the following aspects:
Digital management: Through the information asset management of the meter seal, the management level of the metering equipment is greatly improved.
Improve the anti-counterfeiting performance of the electricity metering seal: adopting two-dimensional anti-counterfeiting code or RFID, greatly improving the anti-counterfeiting of the seal.
Improve the anti-theft performance of the metering equipment: After strengthening the management of the metering equipment, the anti-theft ability of the metering equipment is also greatly improved. This also greatly reduces the possibility of users stealing electricity.
Drive the information management of metering equipment: Through the operation of intelligent seal information management, it can cooperate with the marketing MIS system and generate the ERP information management system to drive the development of the information construction of the power supply company. This also brings a qualitative leap to the measurement management level of power supply units.
Environmental protection: As a metering seal for disposable products, this product does not contain any pollutants and toxic substances, and is easy to recycle. It is a completely green product.
Cost saving: After the construction of this system is completed, an information-based intelligent seal management file is formed, and the life cycle of electronic seals such as storage, requisition, and scrapping is strictly monitored to prevent the waste and loss of power assets.
