Abstract

The invention relates to a power distribution communication network wired link and wireless link mutual backup linkage method and system and an air-ground mutual backup integrated device. The method comprises the following steps that a detection message is sent to the opposite equipment in a power distribution communication network; and if a response signal generated by the opposite equipment according to the detection message is not received within the preset period of time, the data are transmitted to the opposite equipment through the wireless link. The state of the wired link is monitored by using the end-to-end detection technology, and transmission of the service is switched to the wireless link when the wired link is interrupted so that backup of optical fiber wired network and LTE wireless network communication can be realized.

Description

technical field

[0001] The invention relates to the field of power distribution communication networks, in particular to a method and system for mutual backup and linkage of wired links and wireless links in a power distribution communication network, and an air-ground mutual backup integrated device. Background technique

[0002] Industrial Ethernet switches in the smart grid mainly use wired media such as network cables and optical fibers for communication on the network side. In the planning and design stage of power distribution communication networks, the ring networking mode is usually used to improve link reliability. In general, the 220kV / 110kV optical fiber backbone communication network is relatively mature, and the principle of "ring construction" is adopted in the planning and construction stages to meet the "N-1 safety criterion". At the 10kV level, with the implementation of the national distribution network transformation plan, it is necessary to gradually inc...
