Description
Technical field
The present invention relates to technical field of power systems, and in particular to a kind of metering device burglary-resisting system.
Background technology
In electric power metering device technical field, it is necessary to do antitheft processing to electric power metering device.Lead sealing is prevented as one kind
The instrument opened by unauthorized of encapsulation physics, it is functionally similar to latch, and is locked once correctly, unless violence damage, otherwise without
Method is opened, and the lead sealing after destruction can not be restored or reused, so that provable packaged articles were once opened by unauthorized, be played anti-
Tear the effect of antitheft anti-unpacking open, lead sealing obtains extensively should under the various encapsulation occasions such as postal service, logistics transportation, measuring instrument
With.
Existing lead sealing is that lead sealing line is passed through lead sealing through lead sealing string holes mostly, and envelope pincers or print pincers printing mark are applied by lead sealing
When by lead sealing compress clamp lead sealing line, lead sealing and lead sealing line is integrated, since lead seal hole is through state, therefore lead sealing line is in lead
It is in line in envelope, and lead sealing makes for flexible metal materials, in actually protecting, after manually can use the instrument reamings such as small screw tap,
Lead sealing line is extracted, opens lead sealing, lead sealing line is penetrated lead sealing again later can be allowed to restore, therefore easily make there is sled is bored to it
Lead sealing loosens with lead sealing line and extracts the defects of separating and reduce lead sealing and easy lead sealing line out.
2015.09.30, the patent of application number 201510634601.2 discloses a kind of electronic lead sealing, belongs to radio frequency identification
Technical field, including lead sealing shell, knob, lead sealing line, lead sealing valve jacket in the outside of knob, it is characterized in that：Set on the lead sealing shell
Having lead sealing shell to reserve, lead sealing line exports, lead sealing shell reserves lead sealing line import, pawl, and pawl is arranged at lead sealing shell inside top wall
On；The knob includes knob body, knob reserves lead sealing line import, blade, shrapnel, knob bottom plate, and blade is arranged at knob
The top of main body；The knob bottom base plate of the knob is equipped with RFID electronic label, the bottom embedding of the RFID electronic label
The epoxide-resin glue of full saturating electromagnetic wave.
There are problems with for above-mentioned patent：First, card reader scanning RFID electronic label chip in data, when read less than
When data or reading data and different initial data, that is, illustrate that the lead sealing line was destroyed, i.e., above-mentioned electronic lead sealing only has
It can just discover whether to be destroyed in inspection, can not realize Realtime Alerts.
The content of the invention
