Description
Technical field
The present invention relates to electric energy meter detection technique field, the radio frequency read-write card more particularly, on electric energy meter calibrating apparatus
Device fast connecting apparatus and its application method.
Background technology
Bimodulus expense control electric energy meter has local and remote two kinds of expenses control pattern, and wherein local charge control pattern refers to local meter
Amount, local charging, local switch control, remote bill control pattern refers to local metering, long-range main website charging, and passes through long-range main website
Realize switch control.Bimodulus expense control electric energy meter is to carry out security information with the security module that table embeds by RF IC card to interact,
The expense control feature operation such as data enciphering/deciphering, bidirectional identity authentication, Access control is realized, wherein RF IC card is a kind of non-
CPU card is contacted, supports ISO14443A and ISO14443B communication standards.
Expense control electric energy meter is to perform expense control feature operation by solid state medium (RF IC card) under local charge control pattern, therefore
When detecting local charge control pattern radio frequency card reader/writer must be used to write corresponding data in RF IC card according to detection project, then
Triggering electric energy meter expense of being swiped the card on electric energy meter body controls feature operation, such as detects needs when opening an account function and write in RF IC card
Enter information of opening an account, need to write charging information in RF IC card when detecting charging function.
1st, the design application of electric energy meter calibrating apparatus in the market is ordinary electronic formula electric energy meter, and the type is electric
Energy table is not supported to trigger expense control function by solid state medium (RF IC card), therefore electric energy meter calibrating apparatus body is configured without using
In the radio frequency card reader/writer and fixed structure piece of read-write card, and in the market is not exclusively used in connecting on electric energy meter calibrating apparatus yet
With the accessory of fixed RF card reader/writer.
2nd, electric energy meter calibrating apparatus has multiple epitopes, can examine and determine multiple electric energy meters simultaneously, and a radio frequency card reader/writer is only
When can read while write a RF IC card, therefore use electric energy meter calibrating apparatus check fee control electric energy meter local charge control function, have
Two ways：(1) manual operation：One radio frequency card reader/writer is connected with the host computer of electric energy meter calibrating apparatus, by examining and determine people
RF IC card is put into radio frequency card reader/writer and reads and writes card information by upper computer software by member, and then RF IC card is read from radio frequency
Writer is taken out, swiped the card on corresponding checklist, and such iterative cycles are until all epitopes complete swiping card；(2) it is automatic
Change operation：Each epitope of electric energy meter calibrating apparatus installs a radio frequency card reader/writer additional, is manipulated simultaneously by the host computer of device
The radio frequency card reader/writer of all epitopes realizes the automatic read-write card information of batch, simulation swiping card.
Electric energy meter calibrating apparatus will be implemented to transform at present, realize the local charge control work(of automatic detection bimodulus expense control electric energy meter
Can, it is necessary to install a radio frequency card reader/writer additional in each epitope.
First, electric energy meter calibrating apparatus design application not comprising bimodulus take control electric energy meter, device is in itself
Without configuration card reader/writer and mounting structure, the subsequent expansion of device architecture design is also no to include card reader/writer installation.
Second, matching somebody with somebody for connection and fixed RF card reader/writer is not exclusively used on electric energy meter calibrating apparatus in the market
Part, assembled by each electric energy meter calibrating apparatus producer oneself and make fixed connection apparatus, installed generally by radio frequency card reader/writer
Box connects the fixation for realizing radio frequency card reader/writer with mounting box base combination, although single-phase or Three-fee-controlled electric energy meter height base
This consistent but thickness is varied from according to specification function, and various sizes of peace is changed according to the thickness of checklist in calibrating
Mounted box base construction part is to adapt to the change of checklist thickness, it is ensured that the CPU card in tested expense control electric energy meter neck, which is placed in, penetrates
Frequency card reader/writer is effectively read and write in region.This kind of mode parts are more, management inconvenience, and assemble time-consuming, whole economic efficiency
It is low.
The content of the invention
