Embodiment 1

[0034] In this embodiment, aiming at the problem that the quality of 5.8GHz wireless communication is easily affected by obstacles such as towers and leaves, a condition monitoring agent (condition monitoring agent, CMA) device (condition monitoring agent, CMA) device ( Hereinafter referred to as CMA); as other implementation manners, other frequency bands, such as 900 MHz, may also be aggregated.

[0035] In this embodiment, a carrier aggregation radio frequency module is set in the CMA. The carrier aggregation radio frequency module uses the existing carrier aggregation method to realize the configuration of the radio frequency module, which belongs to the prior art. The carrier aggregation radio frequency module is aggregated by the carrier aggregation method 2.4GHz and 5.8GHz frequency band carriers, so as to obtain 13 channels in 2.4GHz and 5.8GHz frequency bands, a total of 26 channels, each channel bandwidth is 20MHz, using DSSS (Direct Sequence Spread Spectrum) technolo...

Embodiment 2

[0063] The difference between this embodiment and the above-mentioned embodiment 1 of the state monitoring agent device is that, as Figure 5 As shown, two carrier aggregation radio frequency modules are set in the CMA in this embodiment, that is, a first carrier aggregation radio frequency module and a second carrier aggregation radio frequency module. The MCU is connected to two 2.4GHz, 5.8GHz carrier aggregation radio frequency modules, and the 2.4GHz, 5.8GHz carrier aggregation radio frequency modules send or receive data through directional antennas.

[0064] like Image 6 As shown, taking CMA1 as an example, the first carrier aggregation radio frequency module and the second carrier aggregation radio frequency module are set in the CMA1 device, the first carrier aggregation radio frequency module and the second carrier aggregation radio frequency module are connected to the MCU, and the CMA1 passes the first carrier The aggregation radio module and the adjacent CMA2 rea...

Abstract

The invention relates to a power transmission line state monitoring agent device, which belongs to the technical field of power transmission line state monitoring, and comprises an MCU and at least one carrier aggregation radio frequency module, and is characterized in that the MCU is connected with the carrier aggregation radio frequency module; wherein each carrier aggregation radio frequency module aggregates a plurality of different frequency bands; the MCU is used for acquiring channel quality information between the MCU and an adjacent state monitoring agent device through the carrier aggregation radio frequency module so as to judge channel quality, controlling the carrier aggregation radio frequency module to switch channels according to the channel quality, and sending a channel switching instruction to the adjacent state monitoring agent device at the same time; moreover, the MCU is also used for controlling channel switching when the carrier aggregation radio frequency module receives a channel switching instruction sent by an adjacent state monitoring agent device, so that the problems of poor quality and low reliability of regional data transmission under poor public network conditions and without an OPGW access point in the prior art are solved.

Description

technical field [0001] The invention relates to a power transmission line state monitoring proxy device, which belongs to the technical field of power transmission line state monitoring. Background technique [0002] Transmission lines are an important part of the power network skeleton, network and functions. Transmission line monitoring aims to timely discover problems such as aging, corrosion, and damage of transmission lines caused by internal and external factors such as dirt, weather, geology, and loads. It is an important part of operation and maintenance work. , has a direct impact on the operation quality of the transmission line and the operation efficiency of the entire power grid. In the actual operation and maintenance work, the periodic monitoring of transmission lines is mainly carried out in three ways: manual inspection, drone inspection and manned helicopter inspection, but there are some outstanding problems in these three monitoring methods: [0003] 1. ...
