Embodiment Construction

[0058] In order to facilitate those skilled in the art to better understand the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. The following is only exemplary and does not limit the protection scope of the present invention.

[0059] The standard gray wolf algorithm (GWO algorithm) simulates the hierarchy and hunting behavior of gray wolves in nature. The whole wolf group is divided into four levels: α, β, δ, and ω. The three decision-making wolves are arranged from high to low, and these three decision-making wolves guide the ω group of wolves to search for the target. The hunting behavior of gray wolves is as follows: figure 1 shown. During the optimization process, the wolves update the positions of α, β, δ, ω.

[0060] The distances between the i-th gray wolf individual and α, β, and δ wolves are as follows:

Abstract

The invention discloses a smart meter wireless sensor network layout method based on the improved gray wolf algorithm, including: S1, setting the wolf population to include the original population and the assisting population, and initializing parameters, including the original population size M, the assisting population size M, and the maximum iteration Times Itermax, search space dimension N and search space upper bound ub and lower bound lb; S2, initialize the gray wolf positions of the original population and the assisting population; S3, calculate the fitness value of each gray wolf in the original population and the assisting population, and respectively Select the wolf with the best fitness value in the first three populations as the decision-making wolf; S4, disturb the position of the decision-making wolf in the original population and the assisting population; S5, sort all the decision-making wolves in the original population and the assisting population , select the top three wolves with the highest fitness value; S6, update the positions of the original population and the auxiliary population respectively; S7, judge whether the iteration termination condition is satisfied: if so, output the position of α wolf as the layout coordinates of the wireless sensor; if not Yes, repeat S3‑S6.

Description

technical field [0001] The invention relates to a smart meter sensor layout method, in particular to a smart meter wireless sensor network layout method based on the improved gray wolf algorithm. Background technique [0002] For a long time, the meter reading of electric energy data in power supply enterprises has been manual meter reading, which requires a lot of manpower and material resources, and there are also difficulties and unsightly aspects in the integrated wiring. With the rapid increase of power load, power companies have handed over the power consumption management business of residents in the community to power companies. Therefore, power companies have increased requirements for electric meters. Research on automatic meter reading technology and product development are imperative. [0003] At present, the data acquisition system based on wireless sensor network can collect instrument information such as instrument data through various instruments. This infor...
