Intelligent device dynamic identification method

Abstract

The invention provides an intelligent device dynamic identification method. The method comprises the following steps: 1) through a background network management program or web management or serial port mode, logging on a switch and searching the ageing time, set to be t-age, of the switch; 2) before an intelligent device is accessed to the switch, detecting the function of the intelligent device and determining frequency of the intelligent device when sending a message out; 3) background management software establishing a device database; and 4) the background management software accessing the switch through a simple network management protocol to obtain a dynamic MAC address and an address table of the switch. According to the method, through the judgment of interval time of sending a heartbeat message, the problem of device address aging in the address table is solved; and the background management software regularly reads the MAC address table of the switch, so that a real-time device connection port can be obtained, and detection of the device and positioning of the fault can be done conveniently.

Description

technical field [0001] The invention relates to a method for dynamic identification of equipment, in particular to a method for dynamic identification of intelligent equipment. Background technique [0002] The intelligent substation divides the automation system into the station control layer, the interval layer and the process layer through the information layering method of IEC61850, so as to realize the digitalization of the whole station information and the networking of the communication platform. In order to realize the management and monitoring of intelligent electronic devices in the network, the devices are usually connected to fixed ports on the network switch, and the switch obtains information such as the connection status and data flow of the device through the snmp agent program, and obtains the connection between network switches through lldp structure, and then the background management program accesses the switch through the snmp client to obtain the topolo...
