Novel electronic anti-counterfeiting system used for electric meter

Abstract

The invention relates to a novel electronic anti-counterfeiting system used for electric meter, comprising a management system, a data acquiring terminal and an E-sealing unit; wherein the management system is connected with the data acquiring terminal, the data acquiring terminal is communicated with the E-seal; the data acquiring terminal transmits a radio wave energy at specific frequency to the E-sealing unit, so as to drive the E-sealing circuit to output internal data while the data acquiring terminal receives and decodes data in sequence and sends the data to the management system for corresponding processing; and half-duplex communication mode is adopted for information exchange between the data acquiring terminal and the E-sealing unit, and meanwhile the data acquiring terminal provides energy and time sequence to the passive E-sealing unit by coupling. The invention has the beneficial effects of small volume, light weight, omniseal, dust prevention, watertightness, corrosion resistance, vibration resistance, impact resistance, resistance to high voltage interference, favourable weatherability, durability, no lead pollution problem, convenient and rapid use, optional implementation before and after sealing and no influence on sealing effect.

Description

technical field [0001] The invention relates to the field of sealing, in particular to a novel electronic anti-counterfeiting system for electric meters. Background technique [0002] Sealing has a long history, is widely used, and is easy to use. Because of its simple structure and sealing logo, it is also easy to copy, so the anti-counterfeiting performance is very poor. The traditional seal needs to rely on the seal tongs to imprint the seal, and to identify whether the seal is legal and valid through the seal on the seal, but the application of the seal tongs cannot effectively solve the anti-counterfeiting problem of the seal and increase the power company's measurement. The management burden of the department; the management of the sealed files needs to be manually recorded by the staff when the seal is sealed on site, and then entered into the computer or directly saved by the manual record file after the seal is sealed. The entire process is cumbersome and backward i...

[0005] 2) The management of seals is chaotic: at present, for the customization, purchase, issuance, sealing, inspection, and unsealing of seals, the metering department of the power company can only record manually, which not only increases the workload but also cannot be corrected. The entire process is strictly and effectively supervised, resulting in unavoidable management chaos

[0006] 3) Metal lead pollution: Most of the most commonly used seals in the domestic market are made of lead, and the random discarding of disposable lead seals will also cause serious lead pollution to the environment. Western developed countries have banned the production and use of metal lead seals. seal up
