1. The use and development of lead seals for power metering equipment
In recent years, some criminals have arbitrarily sabotaged and adjusted power metering equipment, thereby achieving the purpose of evading electricity bills and causing a lot of losses to the country and power supply departments. According to statistics from the State Electricity Department, China loses 20 billion yuan 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 signature of the electric energy meter, which causes the meter to be dialed, wrong wiring, disconnection, etc., which cannot be measured correctly, and the efficiency of the enterprise is greatly infringed, and the national property suffers a huge loss. Therefore, how to use high-tech means to improve the management level, prevent, detect, and plug the loopholes of stealing electricity in a timely manner, and restore economic losses, is an increasingly urgent need for the power sector.
The intelligent seal management system based on RFID technology can solve all the above problems!
2. System introduction
Beijing Xuhang has developed an intelligent seal management system based on the current status of the power industry. The system has functions such as anti-theft, anti-tampering of data, and inspection and supervision. The following is an introduction to the system.
2.1 System advantages:
1. Provide advanced anti-counterfeiting methods to prevent outsiders from forging seals.
- The shape is applied for national patent and 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 fatal weakness of the old-fashioned lead seal that is still restored after being pried.
2. Provide reliable and effective inspection methods to minimize inspection errors caused by subjective factors.
- ? Sealing: Use steel wire (or sealing wire) 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-replicability of the seal number. The seal is printed with a unique code independently defined by the company, which has high security.
- ? Sealing: RFID reader, contactless one-key sealing, simple and fast, at the same time the data of the electronic seal can be collected into the handheld inspection equipment, and then sent back to the host database system for inspection and analysis of whether the data is legitimate.
3. Provide scientific management methods to achieve effective management of the seal itself and internal staff.
- ? Helped the power sector to implement a fully closed-loop management process for power metering equipment.
- ? Through the three-layer anti-counterfeiting design, to ensure that the seal will not be counterfeited and management confusion.
- ? For possible situations in the application, such as loss, damage, etc., a freezing mechanism is designed to unfreeze the seal after it is found, so as to avoid confusion in the application of the seal without wasting it.
- ? Designed the whole process of tracking the seal, when it is found to be damaged, it is convenient to trace back and find the cause of the problem.
- ? The entire business process of the seal is refined management, from warehousing, encryption, disbursement, sealing, inspection, unsealing, review, and scrapping, there are clear operation records for each operation business process, making the use of seals more scientific and reasonable .
2.2 System composition: The system consists of the following parts. As shown below:
Introduction to electronic seals
Handheld terminal introduction
Background management software introduction
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 . (However, the power marketing system must provide a data exchange interface) The following is a flowchart of the entire program.
Three, system function
- ? Realize the whole-process personalized and quantitative management of power metering equipment, and help the power department implement a fully closed-loop management process for power metering equipment.
- ? Realize the entire process of automation of electricity installation, meter reading, electricity inspection, point inspection and other business and information collection, ensuring the reliability of electricity inspection, improving work efficiency, and reducing errors caused by human factors.
- ? Realize the standardization and supervision of the work of internal personnel, facilitate the evaluation and summary of the work done, and provide a basis for clarifying responsibilities and improving work.
- ? Realized data sharing with the MIS system, compatible with the existing meter reading process, and adopted a distributed multi-layer application system based on the B/S structure to ensure the safety, reliability, efficiency and easy maintenance of the system sex. It can achieve a smooth transition from the existing operation process.
4. 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 has been 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 metering equipment: After strengthening the management of metering equipment, the anti-theft ability of metering equipment is also greatly improved. This also greatly reduces the possibility of users stealing electricity.
- ? Promote 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 the power supply unit.
- 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 and environmentally friendly 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 seal storage, requisition, and scrapping is strictly monitored to prevent the waste and loss of power assets.
