Embodiment

[0069] A clustering and data sensing method applied to a wireless sensor in a photovoltaic power station, the method is divided into the following steps:

[0070] Step A. Establish a clustering model:

[0071] Combining the Sierpinski triangle with the hexagonal honeycomb topology to establish a new ideal clustering model proceeds as follows:

[0072] (1) The entire area presents a regular hexagon, which is composed of several regular triangles, with a total of N nodes and a sink node. N sensors are randomly and uniformly distributed in all regular triangle polygonal areas, ignoring edge irregularities.

[0073] The area of ​​the above equilateral triangle is used to determine the size of the cluster, that is, to determine the size of the node N. The area of ​​the equilateral triangle is calculated as follows:

[0074] Assuming that the side length of the equilateral triangle is R, the area of ​​the equilateral triangle is

[0075] Let the node distribution density be λ, a...

Abstract

The invention discloses a clustering and data sensing method applied to a wireless sensor of a photovoltaic power station, belonging to the field of information sensing technology of the electric power Internet of Things, so as to solve the problem that a photovoltaic power station monitoring system constructed based on a wireless sensor network cannot satisfy the collection, sensing and processing of a large amount of data. Problems handled quickly and precisely. The method includes two steps of establishing a clustering model and determining a sensing data collection scheme within the cluster. The model established by the invention is applied to the sensor network topology of photovoltaic power station, which can effectively solve the problem of network load energy consumption, and has the advantages of fault tolerance and load balancing, which can balance network load and save energy consumption, and ensure that photovoltaic power station information is quickly and efficiently perceived. , in the processing and application of the actual data of the photovoltaic power station, the validity and accuracy of the above advantages of the method have been verified.

Description

technical field [0001] The invention belongs to the technical field of information perception of the power Internet of things, and in particular relates to a clustering and data perception method applied to a wireless sensor of a photovoltaic power station. Background technique [0002] At present, many photovoltaic power station monitoring systems are constructed based on wireless sensor networks, which enables extensive interaction between all aspects of the photovoltaic power generation system and improves the scheduling and operation level of photovoltaic power generation. However, due to the limited resources and geographical environment of photovoltaic power plants, many difficulties have been encountered in terms of deployment scale and life, which greatly affects the acquisition and perception of its data and the processing of large amounts of data quickly and accurately. It brings challenges to information transmission and data storage technology. [0003] Compress...
