Description

Technical Field

Background

Many enterprises and institutions use network devices such as computers, servers, printers, fax machines, etc. that are capable of connecting to each other over a private network and communicating with remote locations or the internet via a private communication system, telecommunication service provider, etc. For example, in commercial office buildings, private communication systems may be connected using communication cables that include copper wires or optical fibers. In such a copper or optical fiber connection system, individual connection ports, such as modular wall jacks, are installed in the office of a building. Communications cables or fiber optic cables are installed in the walls or ceilings of the buildings to electrically or optically connect each connection port to a network device (e.g., a network server or network switch) located in a telecommunications closet or computer room. Communications cables or fiber optic cables from external telecommunications providers may be connected within a computer room or telecommunications closet through which enterprise users may access remote servers or the internet.

When a communications cable connection between a device and a network switch is added, removed or removed, the electronic distribution frame may facilitate the movement, addition or change of wiring required in the patch panel to make position adjustments by personnel. And the electronic distribution frame can facilitate technicians to quickly change the path of selected signals without the expense of dedicated switching equipment, the electronic distribution frame is often used to interconnect various communication cables within a computer room or telecommunications closet.

The connection and maintenance of the communication cables interconnecting the network communication devices can have a significant negative impact on the overall network if human error occurs. It is therefore important to keep a record of changes made to patch cord connections in the patch cord field. And the correct recording of any changes in the patch panel site can determine the connection relationship of the patch cord's physical lines, further ensuring that any future changes are entirely correct.

At present, for the management of the connection of interconnected communication cables among network communication devices, the traditional solution is to mark on both sides of a line jump line, a rack of an electronic distribution frame and a wall, generally using adhesive paper labels, and if the connection of the network communication cables is adjusted, a manager records an electronic form. But over time paper labels are very prone to falling off or blurred writing.

In order to facilitate management of the connection problem of communication cables in a network, the communication cable connection is systematically and informationally managed, and an electronic distribution management system is proposed. That is, the existing electronic distribution management system needs to be separately installed with a management host to manage each electronic distribution frame, and one management host can manage a plurality of electronic distribution frames. The management host is responsible for supplying power and communicating for the electronic distribution frame, and the communication protocol is generally a serial 485 protocol; and the management host is connected to the network switch, and then is in communication connection with the remote server, and performs data exchange and transmission. The management system has the advantages of more complex network structure, higher system cost, lower system reliability and more faults. And applied parts are mostly non-standard parts, and the later maintenance operation is very inconvenient. And each electronic distribution frame information display is only expressed by an LED lamp, so that the obtained information is limited and inconvenient to operate when an operator operates on site.
