Problems solved by technology

The power system uses SNMP to monitor the operating conditions of switches, which can only be accessed through multiple RFC-standard MIB library files, resulting in complex system deployment and inconvenient operation and maintenance management.

Embodiment 1

[0013] Such as figure 1 As shown, the present invention is applicable to the communication method of the electric power system switch, the switch 1 in the substation is used as the SNMP agent end; the remote computer 2 is used as the SNMP management end; the switch 1 in the substation and the remote computer 2 communicate based on the MIB library file.

[0014] The switch 1 in the substation acts as an SNMP agent, and uses MIB library files to write corresponding programs to support information exchange with the SNMP management terminal. The remote computer 2, as the SNMP management terminal, uses the MIB library file to obtain information nodes and attributes to support information exchange with the SNMP agent.

[0015] As the SNMP management terminal, the remote computer 2 can obtain and manage all information involved in the MIB library file, including public information, port statistics information, port neighbor information, alarm information, forwarding table information...

Abstract

The invention discloses a communication method for a power system switch. The method is characterized in that the switch in a transformer substation serves as an SNMP proxy end, a remote computer serves as an SNMP management end, and communication between the switch in the transformer substation and the remote computer is carried out based on an MIP library file. The method can meet application requirements of a power system. The MIB library file comprises public information, port statistics information, port neighbor information, alarm information, forwarding table information, flow control information, switch delay accumulative control information, port delay compensation information, network storm suppression information, and priority information. The method provided by the invention is closely integrated with the current operation and maintenance management situation of the power system, so that actual running requirements of the power system can be met.

Description

technical field [0001] The invention relates to the field of communication equipment, in particular to a communication method suitable for an electric power system switch. Background technique [0002] Simple Network Management Protocol (SNMP) is an application layer protocol of the TCP / IP protocol family, and the two sides of the communication are respectively called the network management system and the agent system. Each managed information point in the agent system is represented as an object, and the MIB library file is a collection of these objects. The MIB library file defines a series of attributes of the managed object: the name of the object, the access authority of the object, and the data type of the object, etc. The identifier of the information node in the MIB library file is the path from the root node to the information node, for example, 1.3.6.1.2.1.1.1. This path is called the OID of the information node. Each SNMP agent system has its own MIB library fil...
