Problems solved by technology

[0004] However, the optical switching pressure plate required by the above scheme contains handle switches, relays, and rotating prisms. It also needs to use a network tester and increase the power supply. The components of the scheme are many and complex, and only when the optical fiber network fiber breaks or the transmission fails can it give an early warning. Switching, poor timeliness, low reliability

Abstract

The invention relates to the technical field of power equipment, in particular to a method for switching standby optical-fiber optical ports of a transformer substation process layer network, and electronic equipment. The method comprises the steps that receiving equipment receives a message from sending equipment through a main optical fiber to obtain a state index of a main optical fiber opticalport; when the network state index does not meet the standby optical port starting criterion, the receiving equipment continuously sends a feedback heartbeat message used for monitoring the main optical fiber optical port to sending equipment through a standby optical port; when the network state index meets a standby optical port starting criterion, the receiving equipment sends a GOOSE burst message used for switching the standby optical fiber optical port to the sending equipment through the standby optical fiber optical port; after receiving the message from the sending equipment throughthe standby optical fiber optical port, the receiving equipment stops sending the message to the sending equipment, and the receiving equipment sends a main optical fiber optical port alarm and standby information of the standby optical fiber optical port to complete switching of the standby optical fiber optical port.

Description

technical field [0001] The present application relates to the technical field of electric power equipment, in particular, to a method and electronic equipment for switching a backup optical fiber port of a substation process layer network. Background technique [0002] In view of the advantages of optical fiber communication with strong anti-interference ability, low cost of optical fiber, and low energy consumption in operation, the secondary cable loop of conventional substations is gradually replaced by the optical fiber communication network of smart substations. The process layer network is an important link between the process layer and the bay layer equipment, and undertakes the task of data transmission between the two layers of equipment, and is one of the important guarantees for the realization of the secondary system function. When the main optical fiber port fails, data is transmitted to the original sending device through the standby optical fiber port. [000...
