Embodiment Construction

[0070] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0071] Such as figure 2 As shown, when the present invention works together with external applications, the specific workflow inside the software. When the software is started, the external application sends the calculation information to the system through TCP or memory data exchange, and the operation monitoring and communication scheduling service is responsible for receiving, analyzing and processing. After the task queue is created, the information is sent to the 3D sound field model for data preprocessing and parallelism computing services.

[0072] The list of input data is shown in the table below:

[0073] 1) High-frequency calculation model required parameters (input)

[0074]

Abstract

The invention provides a high-performance three-dimensional sound field calculation system and method. The high-performance three-dimensional sound field calculation system is designed and developed in the form of service and components, wherein the function of each part is relatively independent, so as to form a structure for loose coupling. The high-performance three-dimensional sound field calculation system is characterized in that the high-performance three-dimensional sound field calculation system comprises two main work services and three auxiliary modules, wherein the two main work services are an operation monitoring and communication scheduling service and a three-dimensional sound field model data preprocessing and parallel computing service, and the three auxiliary modules area mapping type file data high-speed analysis module, a computing model state monitoring and control module and a global marine environment database interaction module.

Description

technical field [0001] The present invention is a high-performance three-dimensional sound field computing system, in particular, a three-dimensional sound field computing system capable of supporting multi-dimensional analysis frequencies, multiple data communication modes, self-adaptive hardware platform core numbers, and effectively improving the accuracy and speed of three-dimensional sound field computing. Background technique [0002] The self-adaptive multi-core parallel frequency division three-dimensional sound field analysis system is designed for real-time, fast and accurate three-dimensional sound field forecasting and analysis. At present, our navys marine environment analysis and forecasting capabilities are weak, whether it is the deduction and formulation of combat plans, or the actual Underwater offensive and defensive operations are still at the stage of using the prediction results of the two-dimensional sound field calculation model, which is limited by th...
