Abstract

The invention discloses a photovoltaic power station networking system based on LTE wireless communication. The system comprises an LTE base station, a master station monitoring system, at least one CPE device and at least one terminal device. A VPN function is integrated into the LTE base station. Each CPU device is equipped with the VPN function. Connection with the LTE base station is established by employing an antenna. The master station monitoring system is connected with the LTE base station through an Ethernet. Each terminal device is connected with the corresponding CPE device. According to the architecture, the construction cost is reduced, the coverage range is wide, and the expandability is high.

Description

technical field [0001] The invention belongs to the field of local area network communication, and relates to a method for data interaction between a monitoring system of a master station of a photovoltaic power station and a photovoltaic sub-array and a method for establishing a network structure, in particular to a network structure of a photovoltaic power station based on LTE wireless communication. Background technique [0002] With the rapid development of the domestic photovoltaic industry, large-scale photovoltaic power plants have been built and put into operation in China. At present, the photovoltaic power station adopts the wired communication networking scheme, and the site needs to lay optical cables according to the actual situation, which involves a large amount of civil engineering workload, greatly reduces the work efficiency, and also increases the cost of infrastructure construction, so the construction period is long and the cost is high. The workload is ...
