Photovoltaic array monitoring system based on Internet of Things and working method thereof

Abstract

The invention relates to a photovoltaic array monitoring system based on Internet of Things and a working method thereof. The photovoltaic array monitoring system comprises measurement and control devices distributed on each photovoltaic array, wherein each measurement and control device is connected with an Internet of Things node and is used to upload the collected photovoltaic array data to a base station. The scheme of the invention is used for assisting the establishment of a network and constructing a networking strategy according to environmental information of the network and the distribution characteristics of the nodes, and moreover, in a networking process, the base station mainly communicates with the nodes at the first level, and thus the pressure of the base station can be reduced; and moreover, the networking strategy is mainly distributed to the specific nodes instead of each node, the data transmission amount in the network can be reduced, the networking efficiency canbe improved, and thus the operation and maintenance of large photovoltaic power stations can be satisfied.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a photovoltaic array monitoring system and a working method thereof. Background technique [0002] In recent years, the photovoltaic industry has developed rapidly, and preventing various failures that may occur during the operation of photovoltaic power plants is one of the key issues in the construction of photovoltaic power plants. Effective data collection of photovoltaic arrays during the operation of photovoltaic power plants is conducive to improving system performance and optimizing system structure. [0003] As the scale of photovoltaic power plants becomes larger and larger, the number of photovoltaic arrays in them is also increasing. Therefore, the real-time data monitoring of each photovoltaic array has brought certain pressure on the networking. How to overcome the above technical problems and reduce the To solve the technical problem of excessive load, the present invent...
