Electric field intensity measurement method and device, computer equipment and storage medium

Abstract

The invention relates to an electric field intensity measurement method and device, computer equipment and a storage medium. A voltage signal of a target position with a preset distance from a power transmission line in a to-be-measured electric field is obtained, the temperature and the humidity of the to-be-measured electric field are obtained, the obtained voltage signal, the temperature and the humidity are input into a prediction model, and the electric field intensity output by the prediction model is obtained and serves as the electric field intensity corresponding to the target position in the to-be-measured electric field. The prediction model can be obtained by training through a preset machine learning algorithm based on a plurality of known temperature values, a plurality of known humidity values and a plurality of known voltage signals. Compared with a traditional mode of measuring the electric field intensity based on a nematic liquid crystal photonic crystal fiber penetration mode, in the scheme of the invention, the electric field intensity of the target position is obtained through the prediction model by utilizing the voltage signal at the preset distance from the power transmission line in the to-be-measured electric field and considering factors such as temperature and humidity of the to-be-measured electric field, and the electric field intensity measurement precision is improved.
