Description
Technical Field
The invention relates to application of an RFID technology in a network vascular system, in particular to a universal RFID reader antenna array for an intelligent network vascular system and external equipment thereof.

An embedded intelligent electronic distribution frame based on a Radio Frequency Identification (RFID) technology has been widely paid attention since the advent of the prior art, and the unique identifier of a target object specific to the RFID technology is utilized to realize the intelligent management of a network access layer port, a jumper wire and even the whole network maintenance system. However, with the gradual popularization and application of the product, the defects of the product are gradually displayed, and the product is mainly specifically as follows:
1) The RFID reader antenna array is integrated with the distribution frame in an embedding way, so that when the existing network system is intelligently updated and modified, the existing distribution frame which is in use is completely abandoned and replaced by a new electronic distribution frame embedded with the RFID reader antenna array;
2) The intelligent jumper with the RFID chip, which is matched with the antenna array of the existing embedded RFID reader-writer, is required to be produced and assembled in advance in factories and cannot be assembled in real time on a construction site, which means that when the existing system is updated and reformed, the existing distribution frame is required to be replaced, and the jumper matched with the existing distribution frame is required to be replaced, so that the existing jumper cannot be used continuously;
3) Because the embedded connection structure is adopted, the antenna array of the embedded RFID reader-writer cannot be used on switch products in the network, so that the switch products widely used in the network cannot be brought into the management range, and the intelligent network maintenance system developed on the basis cannot effectively and comprehensively manage the network wiring system;
4) Because the relative position and distance between the RFID chip of the identified jumper wire and the reader-writer antenna embedded above the port of the distribution frame in the system can change under the action of natural external force in the process of installation and use, unexpected false alarm can be caused, and the reliability of the system is reduced;
5) Because of the above two points 1) and 2), when the existing non-intelligent system is integrally modified, the whole network must stop working for a period of time and replace the existing equipment, thus not only causing the waste of the existing equipment which can be normally used, but also failing to meet the requirements of some specific application scenes, such as the occasion that the system is uninterrupted in work or the system upgrade must be in seamless transition.
The defects obviously increase the cost of intelligent upgrading and reconstruction of the system and limit the applicable places of the system, so that the use will of a user is reduced to a certain extent, and the popularization and the use of the intelligent network maintenance system are influenced and limited.
