Best mode for carrying out the invention
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
FIG. 1 is a schematic diagram of a system environment for implementing a method for acquiring operating state data of power distribution network equipment according to an embodiment of the present invention; the system comprises a distribution network communication operation supporting system and a plurality of communication devices, wherein the types of the communication devices comprise Ethernet devices, PON devices, TD-LTE devices and carrier wave devices, and the communication devices comprise but are not limited to routers, switches, servers or workstations.
The bottom layer interface of the distribution network communication operation support system supports an SNMP (Simple network management Protocol) standard, a CORBA (Common Object Request broker architecture) standard, a Telnet (a member of the TCP/IP Protocol family) standard, and a Socket standard. The ethernet device and the PON device both support the SNMP standard, and therefore each of the ethernet device and the PON device includes an MIB (management information base) for collecting and storing management information; a set of management objects accessible via the SNMP protocol is defined in the MIB, and a number of management objects may be represented in a tree structure.
In the embodiment of the invention, a related matching library is also established for the equipment with different models in the distribution network communication operation support system and is used for storing the definition of the management object by the MIB library of the corresponding equipment. The distribution network communication operation support system also stores a device for acquiring the operation state data of the distribution network equipment, and the device can be used for realizing the method for acquiring the operation state data of the distribution network equipment in the embodiment of the invention.
With reference to fig. 1 and the above description of the system environment, an embodiment of a method for acquiring operation state data of power distribution network equipment is described below.
FIG. 2 is a schematic flow chart diagram of a method for obtaining operating state data of power distribution network equipment according to an embodiment; as shown in fig. 2, the method for acquiring the operation state data of the power distribution network device in this embodiment includes the steps of:
s11, acquiring the information of the communication equipment on the network, and identifying the equipment type of each communication equipment;
in this embodiment, the communication device includes, but is not limited to, a router, a switch, a server, or a workstation, and the device types include an ethernet device, a PON device, a TD-LTE device, and a carrier device. For example: common manufacturers of ethernet devices include manufacturers in MOXA, restranda, rogencon, eastern earth technologies, hua san, excellence, etc., and typical device models include Gazelle S1006i, Gazelle S1010i, Gazelle S3028i, PT _7710, PT _7728, SICOM3005A, RS900, etc.; carrier devices such as a primary carrier device and a secondary carrier device of the kozak; PON equipment such as equipment from Michelia and Huacheng vendors, and TD-LTE equipment such as 230MHZ and 1.8GHz equipment from Putian. This is not to be taken as an example.
After networking is successful, the distribution network communication operation support system can identify the equipment type of each communication equipment by acquiring the information of the communication equipment on the network.
S12, inquiring a preset communication mode library according to the device type, and determining a data communication mode corresponding to each communication device; the communication mode library stores the corresponding relation between the equipment type and the data communication mode;
in a preferred embodiment, all types of communication equipment which are already put into the power distribution network can be collected in advance, and corresponding data communication modes are distributed to different types of communication equipment; and establishing a communication mode library to store the corresponding relation between the equipment type and the data communication mode.
In a preferred embodiment, assigning corresponding data communication modes to different types of communication devices comprises: allocating a data communication mode of SNMP + Telnet to the Ethernet equipment, and allocating an SNMP data communication mode to the PON equipment; and allocating a CORBA data communication mode for the TD-LTE equipment and allocating a Socket data communication mode for the carrier equipment.
S13, the operation state data of each communication device is acquired according to the corresponding data communication mode.
In a preferred embodiment, since the data communication mode corresponding to the ethernet device includes an SNMP mode and a Telnet mode, the process of acquiring the operation status data of the ethernet device may be: firstly, acquiring running state data of the Ethernet equipment according to an SNMP mode; and if the data acquisition fails, acquiring the running state data of the Ethernet equipment according to a Telnet mode. The specific process of acquiring the operating state data of the corresponding communication device according to the SNMP data communication mode may include: collecting MIB base information of corresponding communication equipment by using an SNMP interface; a management object which can be accessed through SNMP is defined in the MIB base, and the management object comprises operation state data; acquiring matching library information associated with the communication equipment, wherein the matching library information comprises definition of running state data in an MIB (management information base) of the communication equipment; and acquiring the running state data of the communication equipment from the MIB base information according to the matching base information.
In another preferred embodiment, before obtaining the matching library information associated with the communication device, the method further comprises the steps of: acquiring the model of the communication equipment, and analyzing the MIB library characteristics of the communication equipment with different models; and establishing a related matching library for each type of communication equipment according to the MIB library characteristics, wherein the related matching library is used for storing the definition of the MIB library of the communication equipment with the corresponding type on the running state data.
In the above embodiment, the SNMP consists of a set of standards for network management, TCP/IP based application layer management protocol. The SNMP managed network is mainly composed of managed devices, SNMP agents and a network management system, wherein the managed network devices are provided with respective Management Information Bases (MIBs) for supporting upper-layer applications to collect and store management information of the managed devices. SNMP V1 and SNMP V2 collected data variables for individual devices in a large MIB and after second generation MIB-II release, The Internet Engineering Task Force (IETF) took different strategies, allowing The release of many separate MIB documents, each defining data variables for a specific type of device. Therefore, the upper network management system supported by the SNMP protocol can acquire various kinds of operation information of the network equipment by calling public and private MIB libraries. Because most power distribution network Ethernet switches and PON equipment have complete MIBs, the network management functions of manufacturers of the equipment are lost, and the software interface implementation technology has the advantages of flexibility and convenience, the network management library-based network management acquisition mode is mainly adopted by the distribution network communication operation support system for the integrated interfaces of the running states of all the power distribution network Ethernet switches and PON equipment. Therefore, the distribution network communication operation support system can acquire various information of Ethernet equipment or PON equipment of different manufacturers and different models through the SNMP; the comprehensiveness of information acquisition is facilitated.
In the above embodiments, Telnet is the standard protocol and the main mode of Internet Telnet service, is part of the TCP/IP protocol cluster, and provides the user with the ability to perform remote host work on the local computer, and the Telnet program is used on the end user's computer, and is used to connect to the server, and the end user can input commands in the Telnet program, which will run on the server as if directly input on the server's console. The interface defined by Telnet can be used for realizing information interaction between the interface terminal and the terminal. Therefore, based on Telnet, the distribution network communication operation support system can establish a network Virtual terminal NVT (network Virtual terminal) through a software means to communicate with remote communication equipment, so that the aim of collecting various indexes is fulfilled. The network management acquisition mode based on Telnet has the advantages of strong universality and wide applicable network equipment range, but because Telnet is used for simulating the operation of a virtual terminal, the current operation and the next operation have strict operation sequence requirements, and the efficiency of interface data acquisition is not high. Under the condition that part of Ethernet equipment can not support the SNMP + MIB mode, the collection of the running state of the equipment can be realized by adopting a Telnet-based mode.
In the above embodiment, CORBA is a distributed object computing middleware standard proposed by an Object Management Group (OMG), and a northbound interface facing a network management platform usually uses CORBA technology as a main interface mode for network management acquisition, and because this mode is not directly facing to a device, the CORBA has higher acquisition efficiency and performance reliability; communication equipment suppliers with standardized and reliable network management platforms usually have mature northbound interfaces, and the CORBA technology is a main network management northbound communication mode; as the TD-LTE 4G network which takes 1.8G and 230M as main frequency bands in the power distribution network generally has a network management platform. Therefore, the distribution network communication operation support system can mainly adopt the CORBA technology to the integrated interfaces of the network operation states of all TD-LTE equipment, and can automatically and synchronously acquire the distribution network operation state data such as the station account, the operation state data and the like of the base station, the base station controller and the terminal.
In the above embodiment, SOCKET is a SOCKET specification with TCP and UDP as main transport layer protocols, and since the SOCKET shields the difference between the underlying communication software and the specific operating system, it is possible to communicate between any two computers or virtual machines installed with TCP protocols or implementing SOCKET specifications. In the Windows system environment, the socket interface mainly includes three types, namely streaming socket, datagram socket, and primitive socket. The application program sends requests to a target IP and a designated port of the network equipment through the socket, the server monitors and waits for a connection request sent by the client under the designated port by using a Serversocket, once the connection is established between the client and the server, a session is generated immediately, and data interaction is carried out. The network management acquisition mode of SOCKET has low data acquisition efficiency, and is only used under the condition that other network management acquisition modes are inconvenient to realize. Therefore, when the distribution network communication operation support system adopts other network management interface integration technologies to realize the acquisition of data of certain communication equipment, the network management acquisition mode based on SOCKET can be adopted to realize the acquisition of the operation state data of the communication equipment.
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 be stored in a preset real-time state table according to the device identifier corresponding to each communication device; the real-time state table takes the device identification as an index; according to the real-time state table, the running state of the power distribution network can be evaluated in real time, and the running state of the power distribution network can be managed and controlled finely.
Referring to fig. 3, in a preferred embodiment, the obtained data may be stored as follows, including the steps of:
firstly, inquiring the real-time state table according to equipment identification, and detecting whether a data record corresponding to the communication equipment exists in the real-time state table; if the data record corresponding to the communication equipment exists, updating the corresponding data record according to the acquired running state data of the communication equipment; and if the data record corresponding to the communication equipment does not exist, inserting a new data record into the real-time state table so as to store the running state data of the corresponding communication equipment.
In a preferred embodiment, the operating state data includes fault interruption information, such as a fault start time and a fault clearance time. The evaluating the operation state of the power distribution network according to the real-time state table comprises the following steps: calculating the on-line rate and the completion rate of the electric room in the power distribution network according to the fault interruption information, wherein the specific process comprises the following steps:
the time period for the state evaluation is set, for example, one month as a statistical period.
Acquiring corresponding fault interruption information from the real-time state table according to the statistical period, and calculating the total interruption duration of each communication device in the set statistical period:
SUM (total interrupt duration) Tb2+Tc1+Td1+Tf2 (1)；
Wherein, referring to FIG. 4, TbThe time length T corresponding to the fault of the initial time in the last statistical period and the elimination time in the statistical period is showncThe time length T corresponding to the fault of which the starting time and the removing time are both in the statistical period is showndThe time length T corresponding to the fault of the starting time in the statistical period and the eliminating time in the next statistical period is shownfAnd the time length corresponding to the fault of the starting time in the last statistical period and the eliminating time in the next statistical period is shown. T in FIG. 4aAnd TeNo calculations are included as they are independent of the present statistical period.
Further, calculating the online rate and the completion rate of the electric room where each communication device is located in the statistical period according to the total interrupt duration:
#
wherein, T represents a time duration corresponding to a statistical period, SUM (number of records in the grid electric room) represents the total number of electric rooms operated in the grid, and the electric rooms are used for installing communication equipment in the power distribution network.
For convenience of explanation, in this embodiment, the line rate and the integrity rate are counted by taking the electric room as a statistical unit, and in the statistical method, it is assumed that only one corresponding communication device is located in each electric room. If a plurality of communication devices are installed in one electric room, the electric room is in a normal operation state only when all the communication devices are in normal communication, correspondingly, the calculation method for counting the on-line rate and the completion rate of the electric room in the counting period adjusts the adaptability, and the SUM (total interrupt time) in the calculation method is adjusted to be the total interrupt time of all the devices in the electric room.
According to the method for acquiring the running state data of the power distribution network equipment, on one hand, the running state data of the Ethernet equipment, the PON equipment, the TD-LTE equipment and the carrier equipment in the power distribution network are acquired by utilizing the combined interface comprising multiple communication modes such as an SNMP + MIB library, a Corba, a Telnet and a Socket, the running state data of different types of equipment in the power distribution network can be synchronized, the running state data is associated with the equipment port and the electric room to which the equipment belongs, and the defects of information lag, inaccuracy and incompleteness caused by manual recording of the running state data are overcome. On the other hand, the online rate and the integrity rate of the power distribution network communication equipment can be calculated through a set of software analysis algorithm of the online rate and the integrity rate, so that the automation level of analysis is improved, and the operation complexity of operation and maintenance personnel is reduced.
