Fig. 1 is a system architecture diagram applicable to the operation and maintenance monitoring method of the optical distribution network provided by the present invention. As shown in fig. 1, the system is composed of a monitoring server, an intelligent terminal client, an RFID scanner, an RFID tag, and a two-dimensional code. And the field maintenance personnel complete operation and maintenance monitoring of ODN service operation of the optical distribution network in real time through the RFID tag, the RFID scanner and the intelligent terminal client. Wherein the service operation type includes, but is not limited to, opening, changing, querying, etc.
In this embodiment, the intelligent terminal client may be connected to the monitoring server through a network to implement data interaction. The intelligent terminal client provides a human-computer interaction interface for operating the ODN service by field operators on site so as to realize a series of operations such as obtaining identification information of a network element to be operated or a network element port, and generating a corresponding field operation record according to an operation type triggered by the current operation and maintenance personnel.
Fig. 2 is a flowchart of an operation and maintenance monitoring method of an optical distribution network according to an embodiment of the present invention. Referring to fig. 2, the operation and maintenance monitoring method of the optical distribution network according to the embodiment of the present invention specifically includes the following steps:
s11, when the operation and maintenance personnel operate the network element to be operated and/or the network element port in the optical distribution network according to the operation and maintenance work order, the identification information of the network element to be operated or the network element port is obtained.
The operation and maintenance work order comprises service operations to be executed and network elements to be operated and/or network element ports corresponding to the service operations.
In practical application, on-site operation of an optical distribution network ODN operation and maintenance worker automatically identifies a to-be-operated network element by using an intelligent terminal, and obtains identification information of the to-be-operated network element or a network element port, thereby confirming the on-site operation. Specifically, each network element and/or network element port in the optical distribution network is provided with an identification code for performing identity identification, and identification information of a network element or a network element port to be operated can be acquired through the identification code.
S12, searching the operation and maintenance monitoring record corresponding to the corresponding network element or the network element port according to the identification information.
In this embodiment, the identification information of the network element or the network element port may be generated in advance according to a preset rule, and is used to uniquely identify the network element or the network element port. The identification information of all network elements or network element ports is stored on the monitoring server.
And S13, generating a corresponding field operation record according to the operation type triggered by the current operation and maintenance personnel, and updating the operation and maintenance monitoring record according to the field operation record.
In this embodiment, the operation and maintenance monitoring record is a field operation and maintenance log of the operation and maintenance personnel, and records field operations performed by the operation and maintenance personnel on the network element or the network element port.
And S14, sending the updated operation and maintenance monitoring record to a monitoring server, so that the monitoring server can monitor the execution state of the operation and maintenance work order according to the received operation and maintenance monitoring record.
In this embodiment, the intelligent terminal client reports the operation and maintenance monitoring record to the monitoring server in a HTTP + RESTFUL mode, where the operation and maintenance monitoring record cannot be tampered, and the monitoring server compares the operation and maintenance monitoring record with the operation and maintenance work order content, so as to automatically determine whether the operation and maintenance work order is finished.
Further, in order to realize the standard execution of the operation and maintenance work order, the operation and maintenance work order is ensured to be completely executed, and no missing business operation to be executed exists. After the updated operation and maintenance monitoring record is sent to the monitoring server, when it is determined that all the service operations to be executed in the operation and maintenance work order are not completed, an operation list returned by the monitoring server is received, wherein the operation list comprises the missing service operations and the network elements to be operated and/or the network element ports corresponding to the missing service operations, so as to instruct current operation and maintenance personnel to execute the missing service operations on the corresponding network elements to be operated and/or the network element ports according to the operation list.
According to the operation and maintenance monitoring method of the optical distribution network, provided by the embodiment of the invention, the digital identification technology is combined with the intelligent application software, the actual field operation record of the operation and maintenance personnel can be obtained, the current operation and maintenance monitoring record is obtained based on the field operation record and is uploaded to the monitoring server, so that the monitoring server combines and compares the operation and maintenance work order according to the operation and maintenance monitoring record, the monitoring on the field execution condition of the operation and maintenance work order is effectively realized, and the operation and maintenance work order is ensured to be executed in a standard manner.
In a specific embodiment of the present invention, before step S11, the method further includes receiving an operation and maintenance work order sent by the monitoring server, so as to instruct a current operation and maintenance worker to perform service operations on the network element and/or the network element port to be operated in sequence according to the operation and maintenance work order.
In this embodiment, the monitoring server stores identification information of all network elements or network element ports, provides a human-computer operation interface for background management, and can implement basic data configuration, such as configuration of an operation and maintenance work order, through a background. And the monitoring server issues the configured operation and maintenance work order to an intelligent terminal client held by the operation and maintenance personnel, and the intelligent terminal client displays the operation and maintenance work order so as to instruct the current operation and maintenance personnel to sequentially perform service operation on the network element and/or the network element port to be operated according to the operation and maintenance work order.
In a specific embodiment of the present invention, the acquiring the identification information of the network element or the network element port to be operated further includes the following steps: the identification information corresponding to the network element or the network element port to be operated is obtained by scanning the identification code of the network element or the network element port to be operated, wherein the identification code comprises a two-dimensional code and/or an RFID electronic tag. The two-dimensional code and the RFID electronic tag carry identification information of a corresponding network element or a network element port.
In the embodiment, the ports of the ODN network are managed in a mode of hybrid use of the two-dimensional code and the RFID electronic tag, and the advantages of the 2 methods are combined to make up for the defects of the two methods. The electronic tag identification technology is adopted in a scene with electronic tag installation and deployment, and only a two-dimensional code mode is adopted in an application scene without an electronic tag. The client application software of the intelligent mobile terminal supports the connection reading of the RFID electronic tag through a wireless network, such as Bluetooth, and can also scan the two-dimensional code through a camera of the intelligent terminal, so that the intelligent mobile terminal can be adapted to most application scenes, and the tray can be identified through the two-dimensional code under the condition that an operator does not have a professional RFID identifier.
Specifically, the two-dimensional code may be pasted on a network element (the network element includes an optical fiber cross box, a fiber distribution box, an ODF rack, and the like) of the ODN system, and the two-dimensional code may also be pasted on a tray in the network element. The intelligent terminal supports scanning of the two-dimension code, the two-dimension code can be positioned to a specific network element or tray through scanning, if a specific port needs to be identified, the tray where the port is located is positioned through scanning the two-dimension code of the tray, and then the port in the tray is selected in client application of the intelligent terminal. For a scene where an electronic tag can be deployed, such as a conventional tray, the distance between ports is not too small, and the electronic tag cannot be installed, the RFID electronic tag is adopted. An RFID tag in a non-stick form may be attached to each port edge such that each port has an RFID tag identification. The invention supports the two-dimensional code scanning through the camera so as to identify the network element, namely the tray, and also supports the connection with the RFID scanner through a wireless network, such as Bluetooth, the RFID scanner can read the RFID electronic tag to the identification information and report the identification information through a wireless link, so that the operation and maintenance monitoring record corresponding to the corresponding network element or the corresponding network element port is searched according to the identification information.
According to the embodiment of the invention, the digital identification technology mixed by the two-dimension code and the RFID is adopted to ensure that the digital identification technology can be applied to various ODN equipment.
Compared with the traditional ODN operation and maintenance mode, the invention has the following advantages and beneficial effects:
1. the real and effective recording of ODN operation and maintenance field operation behaviors is realized, the condition that resources are disconnected from a work order management system and field operation in the original ODN operation and maintenance system is avoided, and the automatic supervision of the work order field execution condition is realized.
2. Because the RFID electronic tags can be adopted for management in most scenes, the RFID electronic tags are high in identification speed and can identify specific ports; for the situation that the RFID electronic tag cannot be adapted to all scenes, for example, the RFID electronic tag cannot be adhered to some scenes, a mixed mode can be adopted, and two-dimensional code supplement is used in the situation that the RFID electronic tag cannot be used at least. The mixed mode of the two-dimensional code and the RFID electronic tag can be used for dealing with trays in various forms and installation and deployment environments, and the two-dimensional code and RFID electronic tag can be basically adapted to most of optical cross-connecting boxes, fiber distribution boxes and ODF frames in the market.

Further, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred and that no particular act is required to implement the invention.
