S11, acquiring information of communication devices on the network, and identifying the device type of each communication device;

In this embodiment, the communication devices include but are not limited to routers, switches, servers, or workstations, and device types include Ethernet devices, PON devices, TD-LTE devices, carrier devices, and the like. For example, common manufacturers of Ethernet equipment include MOXA, Resconda, Roger Kang, Dongtu Technology, H3C, and Zhuoyue. Typical equipment models include GazelleS1006i, Gazelle S1010i, Gazelle S3028i, PT_7710, PT_7728, SICOM3005A , RS900, etc.; carrier equipment such as the main carrier equipment and secondary carrier equipment of Keda Intelligent; PON equipment such as ZTE and Huawei and other manufacturers' equipment, TD-LTE equipment such as Potevio's 230MHZ and 1.8GHZ equipment. Not listed here.

After successful networking, the distribution network communication operation support system can identify the device type of each communication device by acquiring the information of the communication devices on the network.

S12, query a preset communication mode library according to the device type, and determine the data communication mode corresponding to each communication device; the communication mode library stores the correspondence between the device type and the data communication mode;

In a preferred embodiment, all types of communication devices that have been put into the power distribution network can be collected in advance, and corresponding data communication modes can be assigned to different types of communication devices; and a communication mode library can be established to store device types and data communication modes. Correspondence.

In a preferred embodiment, allocating corresponding data communication modes for different types of communication devices includes: allocating SNMP+Telnet data communication modes for Ethernet devices, allocating SNMP data communication modes for PON devices; allocating CORBA for TD-LTE devices. Data communication mode, assign Socket data communication mode to the carrier device.

S13: Acquire the running state data of each communication device according to the corresponding data communication mode.

In a preferred embodiment, since the data communication mode corresponding to the Ethernet device includes the SNMP mode and the Telnet mode, correspondingly, the process of acquiring the operating status data of the Ethernet device may be: first, obtain the data of the Ethernet device according to the SNMP mode. Running state data; if the data acquisition fails, then obtain the running state data of the Ethernet device according to the Telnet mode. Wherein, the specific process of obtaining the operating status data of the corresponding communication device according to the SNMP data communication mode may include: using the SNMP interface to collect the MIB library information of the corresponding communication device; the MIB library defines management objects that can be accessed through SNMP , the management object includes running state data; obtain matching library information associated with the communication device, where the matching library information includes the definition of the running state data in the MIB library of the communication device; according to the matching The library information acquires the running state data of the communication device from the MIB library information.

In another preferred embodiment, before acquiring the matching library information associated with the communication device, the method further includes the steps of: acquiring the model of the communication device, analyzing MIB library features of different types of communication devices; and according to the MIB library feature: Each type of communication device establishes an associated matching library for storing the definition of the running state data in the MIB library of the corresponding type of communication device.

In the above embodiment, SNMP is composed of a set of network management standards, and is an application layer management protocol based on TCP/IP. The network managed by SNMP is mainly composed of three parts: managed devices, SNMP agents and network management systems. The managed network devices all have their own management information bases (MIBs) to support upper-layer applications to collect and store their management information. SNMP V1 and SNMP V2 collect the data variables of each device in one big MIB, and after the release of the second-generation MIB-II, the Internet Engineering Task Force (IETF for short) adopted different strategies to allow Publish a number of separate MIB documents, each of which defines data variables for a specific type of device. Therefore, with the support of the SNMP protocol, the upper-layer network management system can obtain various operating information of network devices by calling public and private MIB libraries. Since most of the distribution network Ethernet switches and PON devices have complete MIBs, and the manufacturers of these devices lack the network management function, the software interface implementation technology has the advantages of flexibility and convenience. Therefore, the distribution network communication operation support system is necessary for all distribution networks. The integrated interface of the running status of the Ethernet switch and PON equipment mainly adopts the network management collection method based on the MIB library. Therefore, through the SNMP protocol, the distribution network communication operation support system can obtain various information of different manufacturers and different types of Ethernet equipment or PON equipment; it is beneficial to the comprehensiveness of information acquisition.

In the above-mentioned embodiment, Telnet is the standard protocol and main mode of Internet remote login service, is a part in the TCP/IP protocol cluster, and it provides the user with the ability to complete the remote host work on the local computer, and the terminal user's computer Use the telnet program on the server, use it to connect to the server, end users can enter commands into the telnet program, and these commands will be run on the server as if they were entered directly on the server's console. The interface defined by Telnet can be used to realize the interface terminal and terminal-oriented information exchange. Therefore, based on Telnet, the distribution network communication operation support system can establish a network virtual terminal NVT (Network Virtual Terminal) by means of software to communicate with remote communication equipment, so as to achieve the purpose of collecting various indicators. The advantages of the Telnet-based network management collection method are that it has strong versatility and is suitable for a wide range of network devices. However, because Telnet simulates the operation of virtual terminals, the current operation and the next operation have strict operation sequence requirements, and the efficiency of interface data collection is not high. high. If some Ethernet devices cannot support the SNMP+MIB library method, the Telnet-based method can be used to collect the device running status.

In the above embodiment, CORBA is a distributed object computing middleware standard proposed by the Object Management Group (OMG). Its northbound interface facing the network management platform usually uses CORBA technology as the main interface method for network management collection, because this method is not directly oriented to equipment. , with high collection efficiency and performance reliability; communication equipment suppliers with standardized and reliable network management platforms usually have mature northbound interfaces, and CORBA technology is the main northbound communication method for network management; , 230M is the main frequency band TD-LTE 4G network generally has a network management platform. Therefore, the distribution network communication operation support system can mainly use CORBA technology for the integrated interface of the network operation status of all TD-LTE equipment, and automatically implement the distribution network operation status data such as the base station, base station controller, terminal realization account, and operation status data. Synchronized acquisition.

In the above-mentioned embodiment, SOCKET is a socket specification with TCP and UDP as the main transport layer protocols. Since the socket shields the difference between the underlying communication software and the specific operating system, any two computers are installed with the TCP protocol or implemented. Communication between computers or virtual machines that have the socket specification becomes possible. In the Windows system environment, socket interfaces mainly include stream sockets, datagram sockets and raw sockets. The application sends a request to the target IP of the network device and the specified port through the socket. The server uses the ServerSocket to listen and wait for the connection request sent by the client under the specified port. Once the connection between the client and the server is established, the session is generated immediately, and data interaction. SOCKET's network management collection method is not efficient in data collection. It is only used when other network management collection methods are inconvenient to implement. Since there is no professional manufacturer's network management for carrier communication, the types and quantities of network operation data are not large. Therefore, when it is difficult for the distribution network communication operation support system to collect the data of some communication devices by using other network management interface integration technologies, the SOCKET-based network management collection method can be used to realize the operation status data of these communication devices. collection.

In a preferred embodiment, after the operation state data of each communication device is acquired according to the corresponding data communication mode, the operation state data of each communication device can also be stored in a preset real-time state according to the device identifier corresponding to each communication device. In the table; the real-time status table is indexed by the device identification; according to the real-time status table, the operation status of the distribution network can be evaluated in real time, which facilitates the refined management and control of the operation status of the distribution network.

Referring to Figure 3, in a preferred embodiment, the acquired data can be stored as follows, including steps:

First, query the real-time status table according to the device identifier to detect whether there is a data record corresponding to the communication device; If there is no data record corresponding to the communication device, insert a new data record into the real-time state table to store the running state data of the corresponding communication device.

In a preferred embodiment, the operating status data includes failure interruption information, such as failure initiation time and failure removal time. The evaluating the distribution network operating state according to the real-time state table includes: calculating the on-line rate and the intact rate of the power room in the distribution network according to the fault interruption information. The specific process is for example:

Set the time period for status evaluation, for example, take one month as a statistical period.

Obtain the corresponding fault interruption information from the real-time status table according to the statistical period, and calculate the total interruption duration of each communication device within the set statistical period:

SUM (total interruption duration)=T _b 2+T _c 1+T _d 1+T _f 2 (1);

Among them, as shown in Figure 4, T _b represents the time length corresponding to the fault whose starting time is in the previous statistical period and the elimination time is in this statistical period, and T _c indicates that the starting time and elimination time are both in this statistical period The duration of the fault corresponding to the fault, T _d represents the duration corresponding to the fault whose starting time is in the current statistical period and the elimination time is in the next statistical period, T _f means the starting time is in the previous statistical period, and the elimination time is in the next statistical period. The duration corresponding to the fault in the statistical period. _Ta and _Te in Figure 4 are not included in the calculation because they are not relevant to this statistical period.

Further, according to the total interruption duration, calculate the online rate and the integrity rate of the power room where each communication device is located within the statistical period:

#

#

#

Among them, T represents the duration corresponding to a statistical period, and SUM (the number of records in grid power rooms) represents the total number of power rooms running on the grid, and the power rooms are used to install communication equipment in the distribution network.

For the convenience of description, in this embodiment, the power room is used as the statistical unit to count the online rate and the intact rate, and the above statistical method assumes that there is only one corresponding communication device in each power room. If multiple communication devices are installed in a power room, the power room is in normal operation only when all the communication devices communicate normally. Correspondingly, the online rate and the integrity of the power room in the statistical period are counted. The calculation method of the rate will be adaptively adjusted, and the SUM (total interruption time) in it will be adjusted to the total interruption time of all equipment in the power room.

It overcomes the shortcomings of information lag, inaccuracy and incompleteness caused by manual recording of operating status data. On the other hand, through a set of software analysis algorithms for online rate and integrity rate, the online rate and integrity rate of distribution network communication equipment can be calculated, which improves the automation level of analysis and reduces the operational complexity of operation and maintenance personnel.
