Remote intelligent electronic seal device

Abstract

The invention provides a remote intelligent electronic seal device, including a one-chip microcomputer, an RFID chip, a conductor seal wire inserted in a door hole in a metering box, a detection module used for detecting conduction of the conductor seal wire, a wireless communication module used for wireless connection with a background management system, a DI input module used for jointing an external DI point, and a wireless charging circuit used for supplying power to a whole digital seal terminal recognizer. The invention also provides a metering box anti-electricity larceny method. When the worker performs onsite sealing, the recognizer is used for sending information of a device and an added metering seal to a management master station; during onsite seal detection, the recognizer is used for reading seal information and sending the seal information to the background management system; and when electricity larceny appears and the conductor seal wire is destroyed, the detection module detects that the conductor seal wire is not conducted, communicates with the background management system through the wireless communication module of the remote intelligent electronic seal device and triggers alarming. The invention can prevent electricity larceny due to power destroy and metering seal forgery.

Description

technical field [0001] The invention relates to an electronic sealing device, in particular to a remote intelligent electronic sealing device. Background technique [0002] Lead seal, also known as metering seal, is a traditional device for blocking metering equipment, anti-counterfeiting and preventing illegal opening of metering devices to cheat, and is used to prevent opening and destruction of metering equipment. The lead seals currently used have a long history, are widely used, and are easy to use. Because of their simple structure and sealing marks, they are also easy to copy, so the anti-counterfeiting performance is very poor. Line loss is an important economic and technical index for power grid enterprises. A line loss management system suitable for commercial operation should be established to reduce the line loss rate to a reasonable level and strive to improve the economic benefits of the enterprise. Electricity stealing is an important cause of line loss. Stre...

Problems solved by technology

Electricity theft is an important cause of line loss. Strengthening the prevention and control of electricity theft is an important task for power supply companies to reduce line loss. However, the seals currently used have disadvantages such as simple structure, poor anti-counterfeiting technology, and easy imitation, which are not good. Complete the purpose of preventing electricity theft
