Abstract

The invention discloses a power transmission line monitoring data transmission system comprising a central server and a plurality of first-layer data acquisition units; the plurality of first-layer data acquisition units are of a series structure, and the adjacent first-layer data acquisition units are in communication connection through a first-type transmission protocol and / or a second-type transmission protocol; The tail end node of the first-layer data acquisition unit is connected with the central server through a third-type transmission protocol; Each first-layer data acquisition unit isconnected with a plurality of second-layer data acquisition units through a fourth-type transmission protocol; Wherein the first type of transmission protocols are long-distance and large-data-volumetransmission protocols, the second type of transmission protocols are low-power-consumption and small-data-volume transmission protocols, the third type of transmission protocols are Internet of Things communication protocols, and the fourth type of transmission protocols are near-field communication protocols. The system can construct a network for transmitting data in a cellular-free mobile data network area, and can obtain the highest data transmission efficiency with the lowest energy consumption.

Description

technical field [0001] The invention relates to the field of electric power data acquisition, in particular to a power transmission line monitoring data transmission system. Background technique [0002] In transmission network corridor areas, especially in mountainous and hilly areas, there is no 4G signal, or even 3G / 2G signal. Data collected by an optical transient platform used to monitor environmental data on power lines cannot be transmitted back. In response to this situation, we need to build an ad hoc network system, which allows the data collected by the platform and the data of various sensor modules on the periphery of the platform to transmit the data to the central server through the network of components. Then build an IoT ecosystem and form a complete transmission network data transmission chain. Contents of the invention [0003] The object of the present invention is to provide a transmission line monitoring data transmission system for the above existi...
