Because the network element name is unique, all passive devices can find out the corresponding network element in the network management through the local side network element and the port (network element name) to which the passive device belongs, then occupy the channel, calculate the corresponding far-end port (the relationship between the channel and the port is static corresponding), and generate the connection object with the local side network element and the port information. The passive device identification code includes, but is not limited to, an SN code and a two-dimensional code, and in the first embodiment, the SN code is selected.
In a specific scenario in this embodiment, for example, after an engineering constructor completes construction of a certain passive device on a construction site, an SN number of a current passive device and corresponding construction type and construction information are entered in a terminal device in a manner that the terminal device on a mobile phone scans an SN code of a device body or manually inputs the SN number.

After the passive device information table is updated, the background service records the corresponding operation information into the operation log table, and the index fields in the table are sequentially increased according to the writing of the entries of the data table. The structure of the operation log table is shown in table two:

the network management system is divided into two synchronization modes of periodic synchronization and one-time synchronization.
In this embodiment, according to different usage scenarios, the network management system supports two synchronization modes, namely periodic synchronization and one-time task. The periodic synchronization support includes synchronization in a period of minutes, hours, days, weeks, and months.
The information synchronization of the passive equipment comprises the following steps:
s201: and the data synchronization service reads the synchronization identifier from the network management system.
The synchronization identifier includes two fields: the last operation time and the last operation serial number of the last update. If the synchronization is the first synchronization, the last operation time T is the time T0 of the network management server minus the first synchronization time length T1, and the last operation sequence number I is a default value of 0. The first synchronization duration can be set through a script, and in the first embodiment, the default is 1 year. The data synchronization service can realize the bidirectional interaction between the terminal equipment and the network management system.

And the data synchronization service firstly performs duplicate removal processing after receiving the operation log data set, and only keeps one operation log with the largest operation serial number when the SN code of one passive device corresponds to a plurality of operation logs.
S204: and after the equipment information synchronization is completed, the data synchronization service updates the synchronization identifier to the network management system.
And setting the last operation time and the last operation serial number as the maximum operation time and the maximum operation index of the operation log set obtained this time respectively.

In this embodiment, the passive device identification code is an SN code, belongs to an identifier of a device, and cannot be directly converted into a network element object data structure. If the passive device identification code is a two-dimensional code, after the passive device manufacturer fills all the device information into the two-dimensional code, the device information changes once, for example, the position is moved, and the two-dimensional code needs to be regenerated.
In order to enable the data synchronization service to add the passive device to the network element object management service, in combination with the embodiment of the present invention, there is also a preferred implementation scheme, specifically, as shown in fig. 3, where the data synchronization service adds the passive device to the network element object management service, and the specific method includes:

S402: if the report is the message for adding the network element, the planar coordinate range attributes map Width and map Height in the topology global attributes, and the corresponding Latitude and Longitude coordinate ranges left Longitude, top Latitude, right Longitude and bottom Latitude are read.
For example, in wuhan, the longitude and latitude of a certain passive device obtained through the mobile phone location service are east longitude 114.31(LongitudeX) and north latitude 30.52(point Y). The topological graph range is Hubei, the plane coordinate range of the topological graph is 1600(map Width),960(map Height), the Longitude and Latitude range is east Longitude 108.36(left Longitude) -116.13(right Longitude), north Latitude 29.03(top Latitude) -33.11(bottom Latitude);
