Design scheme of smart grid power meter lock and seal management system

The smart grid power meter lock and seal management system has become a variety of high-tech such as electronic label, barcode, scanning and identification, software, communication, new environmental protection materials, etc., to achieve informationization, refinement and integrated management of seals. The system realizes on-site management and process management by controlling the lock in the process of meter calibration, installation, inspection, and scrapping, thereby realizing the life-cycle process management of the meter.

I. Overview

1. Current status of China's metering seal management

1) It is easy to imitate, easy to open, and difficult to identify;

2) There is a problem of adding seals and using the sealing pliers;

3) The existence of the use does not count, the seal is not marked, the human error causes the internal and external combined stealing electricity;

4) There is a problem that the number of manual identification numbers is large, and the services such as the use, the replacement, the seal, and the electricity check cannot be managed.

5) There is a problem of heavy metal pollution, which is banned in developed countries.

2. Urgent problems

Locking and sealing improvement: anti-theft, environmental protection, and convenient sealing.

Improved coding: barcode, RF code for easy 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 traces the calibration, installation and inspection of the meter through the multi-purpose plastic case lock with unique identification. Cooperate with special software and handheld terminal to bind the meter product number, calibration lock number, installation lock number, and user number of the lock lock number, and link with the electricity marketing MIS system to realize the life cycle process management of the meter to reduce Line loss, the realization of fine management of measurement and monitoring, and the purpose of improving the level of small management.

Second, the system introduction

The lock and seal management system integrates various high-tech such as electronic label, barcode, scanning and identification, software, communication, and new environmental protection materials to realize informationization, refinement and integrated management of seals. The system realizes on-site management and process management by controlling the lock in the process of meter calibration, installation, inspection, and scrapping, thereby realizing the life-cycle process management of the meter.

Third, the lock management software

Realize the functions of library management, storage, distribution, verification, installation, electricity inspection, loss, scrapping, tracking and query, statistical analysis, etc.

Fourth, digital lock

The digital lock is a one-time lock that can be self-locking, anti-opening, with anti-counterfeiting code or RFID chip. It is easy to install and cannot be opened after self-locking. Built-in chip code or molded case laser bar code, use color to distinguish different uses, easy to check with electricity.

Five, scanning identification tools

Identify or scan the meter, lock information, and automatically enter the lock management system software. It is used for verification and sealing, on-site loading and sealing, or electricity inspection and inspection.

All the handheld terminals adopt the international top brand Motorola-Symbol series products.

Handheld terminal embedded: Handheld terminal-specific business software.
