An industrial internet of things channel simulation method and system

Abstract

The application relates to an industrial Internet of Things channel simulation method and system, wherein the method comprises the following steps: collecting two pictures covering the whole scene which need to be simulated by the industrial Internet of Things channel, converting the two scene pictures into point cloud data respectively, and then registering the two groups of point cloud data to obtain complete point cloud data of the whole scene; performing surface reconstruction on the complete point cloud data, and simplifying the number of triangular meshes corresponding to the reconstructed curved surface to a target number by using an improved QEM algorithm; selecting a transmitting point and a receiving point in the scene, and combining the triangular meshes after surface reconstruction to solve a one-time reflection path from the transmitting point to the receiving point, and solve a two-time reflection path from the transmitting point to the receiving point, so as to obtain an average power delay spectrum, an azimuth angle, a pitch angle, an azimuth angle spread, a pitch angle spread and a reflection path, and complete channel simulation. The application can effectively realize fast, accurate and low-cost simulation and analysis of a complex industrial environment channel.
