Embodiment 1

[0053] Such as figure 1 As shown, in Embodiment 1, the SBR-based multi-layer airtight cabin ray tracing method specifically includes creating multiple transfer sources based on the layered iterative idea to receive the rays emitted by the emission source, (the transfer source) is based on the mailbox The technology judges whether the ray is a repeated emission ray, and if so, stops tracking the current ray; if not, forwards the ray to the next transfer source or receiving source. The present invention creates multiple transfer sources based on the layered iterative idea, as the transfer between layers of multi-layer airtight cabins; the transfer source judges whether the rays are repeatedly emitted based on the mailbox technology, avoiding the transfer points / Repeated reception by the receiving source, that is, a reasonable screening of the invalid calculation part that may have double calculation and no contribution to the field strength, reduces the time used for simulation...

Embodiment 2

[0105] This embodiment provides a storage medium, which has the same inventive concept as Embodiment 1, on which computer instructions are stored, and the computer instructions execute the SBR-based multi-layer airtight cabin ray described in Embodiment 1 when running. The steps of the trace method.

[0106] Based on this understanding, the technical solution of this embodiment is essentially or the part that contributes to the prior art or the part of the technical solution can be embodied in the form of a software product, and the computer software product is stored in a storage medium. Several instructions are included to make a computer device (which may be a personal computer, server, or network device, etc.) execute all or part of the steps of the method described in each embodiment of the present invention. The above-mentioned storage medium includes: U disk, mobile hard disk, read-only memory (Read-Only Memory, ROM), random access memory (Random Access Memory, RAM), ma...

Embodiment 3

[0108] This embodiment also provides a terminal, which has the same inventive concept as Embodiment 1, including a memory and a processor, the memory stores computer instructions that can run on the processor, and the processor runs the The steps of the SBR-based multi-layer airtight cabin ray tracing method described in Embodiment 1 are executed when the computer is instructed. The processor may be a single-core or multi-core central processing unit or a specific integrated circuit, or one or more integrated circuits configured to implement the present invention.

[0109] Each functional unit in the embodiments provided by the present invention may be integrated into one processing unit, or each unit may physically exist separately, or two or more units may be integrated into one unit.

Abstract

The invention discloses an SBR-based multi-layer airtight cabin ray tracing method, a storage medium and a terminal, belonging to the technical field of ray tracing, creating multiple transfer sources based on layered iterative ideas to receive rays emitted by the emission source, and then based on the mailbox The technology judges whether the ray is a repeated emission ray, and if so, stops tracking the current ray; if not, forwards the ray to the next transfer source or receiving source. The present invention creates multiple transfer sources based on the layered iterative idea, as the transfer between layers of multi-layer airtight cabins; the transfer source judges whether the rays are repeatedly emitted based on the mailbox technology, avoiding the transfer points / Repeated reception by the receiving source, that is, a reasonable screening of the invalid calculation part that may have double calculation and no contribution to the field strength, reduces the time used for simulation, greatly reduces the calculation workload, and realizes the multi-layer airtight cabin radiation. Efficient tracking.

Description

technical field [0001] The invention relates to the technical field of ray tracing, in particular to a ray tracing method, a storage medium and a terminal based on an SBR-based multi-layer airtight cabin. Background technique [0002] As a classic algorithm developed based on the powerful computing power of computers, the ray tracing method can identify all possible ray paths between the transceivers of multipath channels, and analyze the amplitude, delay and polarization of each ray according to the theory of electromagnetic wave propagation. Information, etc. are calculated to predict the propagation characteristics of radio waves in the area. [0003] Since the ray tracing method began to appear in the early 1980s, scholars at home and abroad have proposed many classic algorithms, such as the bouncing ray method (SBR, Shooting and BouncingRays method) based on the forward tracking algorithm (Direct Algorithm) and the backward tracking algorithm based on (Inverse Algorith...
