Description
Technical field
The present invention relates to a kind of application of RFID technique in network skeleton, more particularly to a kind of universal RFID to read and write
Device aerial array and its auxiliary products.
Background technology
Based on the embedded intelligence electronic wiring frame of radio frequency identification (RFID) technology, since the advent of the world is closed extensively
Note, using specific to RFID technique to destination object it is unique can identification, realize for network access layer port and jump
The intelligent management of line or even whole network skeleton.But as the progressively popularization and application of the product, its drawback are gradually shown
Show to come, it is main specific as follows：
1) RFID reader aerial array is integrally formed in a manner of inlaying with distributing frame, so to existing network system
When doing intelligentized updating transformation, it is necessary to all abandon existing distributing frame currently in use, be changed to and new be embedded with RFID read-write
The electronic wiring frame of device aerial array；
2) with the matching used intelligent wire jumper with RFID chip of existing embedded RFID reading and writing device antenna array, it is necessary to
In factory, production and assembly are completed as requested in advance, can not be assembled in real time at the construction field (site), this is also meaned that to both
When having the system to do upgrading, not only existing distributing frame will be replaced, but also matched wire jumper also needs to give to replace, and leads
Existing wire jumper is caused to be continuing with；
3) as a result of inserted connection structure, the exchange of Embedded RFID reader aerial array in a network
It can not use, thus widely used interchanger product in network can not be included within range of management on machine product, be caused
The intelligent network skeleton developed on this basis effectively cannot carry out comprehensive management to network wiring system；
4) due to identifying the RFID chip of wire jumper in system and being embedded between the reading and writing device antenna above distributing frame port
Relative position changes with distance in installation and meeting during use under the action of natural external force, thus can cause the non-phase
The false alarm of prestige occurs, so that the reliability of system reduces；
5) due to it is above-mentioned 1), 2) 2 points, when to existing non intelligentization system Overall Reconstruction, whole network must stop work
Make a period of time, existing equipment replaced, thus not only cause it is existing can normal use equipment waste, but also can not expire
Some application-specific scenes of foot, such as system work can not be interrupted or the needs of the occasion of the necessary seamless transitions of system upgrade.
Above-mentioned many drawbacks undoubtedly increase the cost of system intelligent upgrading, and the limit of system application place
System, thus the use wish of user is reduced to a certain extent, influence and limit pushing away for intelligent network skeleton
It is wide to use.
