RFID sealing device of new electric energy meter, and sealing method

Abstract

The invention discloses an RFID sealing device of a new electric energy meter, and a sealing method. The RFID sealing device comprises a fixed cylinder bottom cover which is used for being built in a screw hole in an upper meter cover of the electric energy meter, and a locking clamping cover which is provided with an RFID electronic tag, blocks the fixed cylinder bottom cover and seals a locking screw. Through the technology that the RFID electronic tag is implanted in a clamping cover body, uniqueness is achieved for plastic sealing, the sealing reproduction difficulty is greatly increased, and reliability of secrecy maintaining is enhanced; through the orientation function of the fixed cylinder bottom cover, a notch in the fixed cylinder bottom cover can be matched with a notch in the electric energy meter in a penetrating mode so that a compatible old-threading type sealing function can be achieved; after the locking clamping cover with the RFID electronic tag is used for sealing the electric energy meter, a flat top of a head cover and a shell of the electric energy meter are flush with each other and attractive in appearance, the locking screw is sealed, a thievery prevention effect is good, the reproduction difficulty is high, reliability of secrecy maintaining is high, sealing work is simple, prying prevention is achieved due to the fact that no prying positions exist, automatic assembling and sealing can be achieved, the phenomenon that the electric energy meter can not be opened due to the fact that the locking clamping cover with the RFID electronic tag can not make contact with the locking screw is avoided, and the sealing, secrecy mainlining and electricity stealing prevention effects are achieved for the electric energy meter.

Description

technical field [0001] The invention relates to the field technology of electric energy meter sealing system, in particular to an RFID sealing device and sealing method for a new electric energy meter. Background technique [0002] The energy meter seal is a device to prevent unauthorized people from opening the energy meter, which can prevent unauthorized people from changing the structure or setting of the energy meter to steal electricity. At present, in the power industry, the traditional sealing structure is to use the sealing line to pass through the plastic shell, seal the screw, and then insert the two ends into a sealing structure, and fix the sealing line by pressing or rotating, without damaging the sealing structure and Under the premise of breaking the sealing line, the sealing line cannot be pulled out, so that the sealing screw cannot be rotated, so that unauthorized people cannot unscrew the sealing screw, open the sealed structure, and play the role of seali...

AI Technical Summary

Problems solved by technology

This structure mainly has the following four deficiencies: first, the traditional seal needs to wear the seal line, the installation steps are cumbersome, and the sealing efficiency is low; second, the anti-theft performance of the traditional seal structure is poor; third, the lead used in the traditional seal , serious environmental pollution, and long-term exposure of installation staff to lead, which can easily cause poisoning; Fourth, traditional seals are not conducive to digital management and the need for efficient and automatic sealing

Although the existing technology has made many improvements to the seal structure, some of which do not need to wear the seal line, the installation steps have been simplified, but because the structure is still relatively complicated, and the correction between the seal hole and other parts is required, the installation operation It is cumbersome and cannot be automatically sealed; some improvements in the structure of the seal can temporarily prevent theft, but due to structural defects, the seal is relatively easy to age. After a period of time, the seal will reduce or lose the anti-theft performance. Frequent replacement is required, which increases management costs and is not conducive to implementation
