Abstract

The invention discloses a visual simulation prediction method for electromagnetic radiation of a base station based on a simplified directivity function. Through mathematically simplifying an antennadirectivity attenuation function, practical simplified calculation of any spatial point is realized; each equivalent position curve of the antenna space limit value is predicted to realize predictionof a single-antenna three-dimensional visual contour surface; meanwhile, prediction of a space electromagnetic radiation power density visualization curve in the vertical direction and prediction of aground 1.7 m high electromagnetic radiation power density visualization curve are achieved. Through open design and conventional multi-parameter adjustment, the established prediction model can accurately calculate and visualize the maximum electromagnetic radiation intensity of a certain position of a single base station, has great reference value for rapid site selection of the base station, electromagnetic radiation environment influence visualization evaluation and environment protection visualization, and has certain social benefits.

Description

technical field [0001] The invention relates to the field of base station wire radiation, in particular to a method for visual simulation and prediction of base station electromagnetic radiation based on simplified directivity functions. Background technique [0002] At present, for the prediction of electromagnetic radiation around the communication base station, the calculation of the antenna directional attenuation function is complicated and impractical, and there is no simple and effective method for realizing visualization. In fact, the mathematical simplification of the antenna directional attenuation function and the practical simplified calculation of any point in space are the basis for the spatial calculation, three-dimensional display, and ease of use of the communication base station electromagnetic radiation visualization simulation prediction system. If the maximum transmission power is used to predict the electromagnetic radiation around the base station, the...
