LED lamps will flash, and can quickly find current ink.RFID electronic wiring frame systems have multi-level alarm function.First,
When any link illegally changes, electronic wiring frame can all be found in real time, and be alerted by LED lamps, and alarm is believed
Breath is sent to controller.Controller can send instruction display alarm content and simultaneous voice prompting on screen, and alarm is believed
Breath is sent in background management system.Background management system is intactly shown by the diversified forms such as figure, text, short message, E-mail again
Show all warning information, prompt keeper's timely processing.In addition, background management system can also monitor with special MAC
The terminal of location is illegally changed, and any illegal MAC changes can also be found in time, and be alerted to user.Wire jumper inserts distributing frame
Port when, easily occur being not inserted into place（I.e. half inserts）Situation.
The common distributing frame of such case can not differentiate that single RFID electronic wiring frames can is accomplished.Half is run into insert
When entering state, electronic wiring frame, controller and back-stage management software can all receive warning information.RFID electronic wiring frame structures
Simply, system architecture is exquisite, is non-contact ID technology, it is achieved that the wire jumper across controller is very convenient, even control
Device processed is deployed in different telecommunication closets or across in the equipment room of floor, can be easily accomplished wire jumper.Despite brand-new product,
But common distributing frame can also smooth upgrade be RFID electronic wiring frames, only need on common distributing frame a plug-in RFID
Identifier achieves that upgrading.
A plug-in RFID identifier on common interchanger, it is possible to upgrade to general switch with electronics
The interchanger of distribution holder function.Internet of Things application helps the reciprocal RFID electronic wiring frames system and tradition in cloud computing landing Shanghai
RFID electronic wiring frame technologies have essential distinction.
From the point of view of the integrated level of system, the reciprocal RFID electronic wiring frames in Shanghai have open integrated platform.This is flat
Platform be based on SOA design philosophys can infinite expanding distributed type open software platform framework, have based on RFID and wireless pass
Feel the software middleware of network design, there is hardware intermediate layer of autonomous innovation etc..These structures ensure that the continuous of software function
Extension and the continuous of hardware integrate.
The reciprocal target in Shanghai is that the physical layer for making whole network is accurately monitored and managed, and turns into " RFID wisdom nets
Network ".In RFID wisdom networks, each facility, equipment, cable, the node of networked physics layer are intactly managed
Come, pass through wireless sensor technology and RFID technologies so that physical message is by real-time collecting, by the calculating and optimization in high in the clouds
Strategy, realize monitoring and alarm to physical layer.
RFID wisdom networks are also the necessity of cloud computing development.Cloud brings severeer problem of management, in physics
After layer realizes transparence and automation, the continuous extension of physical layer will bring fatal challenge to optimization and management, and solve
Method is exactly the automation of physical layer, and RFID wisdom network is exactly to solve one of preferred plan of this problem.Come in the long term,
RFID wisdom network will also turn into the indispensable component of cloud platform and function.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to is assert
The specific implementation of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of not departing from present inventive concept, some simple deductions can also be made or substituted, should all be considered as belonging to the present invention's
Protection domain.
