The smart grid power meter lock management system has become a variety of high and new technologies such as electronic labels, barcodes, scanning and identification, software, communications, new environmentally friendly materials, etc., to achieve the informatization, refinement and integrated management of seals. The system realizes on-site management and process management through the control of locks in the process of meter verification, installation, use inspection, scrapping, etc., so as to realize the whole life process management of the meter.
I. Overview
1. Current status of metrological seal management in China
1) There are problems that it is easy to imitate, easy to open, and difficult to distinguish the appearance;
2) There is trouble with sealing, the problem of using sealing pliers;
3) There is a problem that the use is not counted, the seal is not marked, and the artificial leakage causes the internal and external combination to steal electricity;
4) There is a problem that the number of manual identification numbers alone is huge, and services such as receiving, sealing, and electricity inspection cannot be managed in information;
5) There is a problem of heavy metal pollution, which is prohibited in developed countries.
2. Urgently resolved problems
Sealing improvement: anti-theft, environmental protection, and convenient sealing.
Coding improvement: bar code, radio frequency code, easy for tool identification.
Tool improvement: use professional tools to improve efficiency and accuracy.
Management improvement: use lock management system, information management.
The metering lock management system tracks the entire process of the calibration, installation, and inspection of the meter through the multi-purpose plastic shell lock with a unique identification. Cooperate with special software and hand-held terminal to bind the product number of the meter, calibrate the lock number, install the lock number, and use the lock lock number user number, and link it with the electricity marketing MIS system to realize the whole life process management of the meter to achieve reduction Line loss, the realization of fine management of measurement monitoring, and the purpose of improving the level of small-scale management.
2. System Introduction
The lock management system integrates a variety of high-tech technologies such as electronic tags, barcodes, scanning and identification, software, communications, new environmentally friendly materials, etc., to realize the informatization, refinement and integrated management of seals. The system realizes on-site management and process management through the control of locks in the process of meter verification, installation, use inspection, scrapping, etc., so as to realize the whole life process management of the meter.

Three, lock management software
Realize the functions of locked warehouse management, receiving, issuing, verifying, installing, electricity inspection, loss, scrapping, tracking and query, statistical analysis and so on
Four, digital lock
Digital lock is a one-time lock with self-locking, anti-opening, anti-counterfeiting code or RFID chip. It is easy to install and cannot be opened after self-locking. Built-in chip coding or plastic laser bar code, use color to distinguish different uses, easy to check with electricity.
V. Scanning and identification tools
Identify or scan the meter, lock information, and automatically enter into the lock management system software. It is used for verification sealing, on-site installation of table sealing or electricity inspection and inspection.
All handheld terminals adopt the international top brand Motorola-Symbol series products.
Embedded in handheld terminal: dedicated service software for handheld terminal.
