Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0039] The software-defined method of airborne equipment data storage in the present invention is embodied in:

[0040] First, the data storage methods of airborne equipment are diverse and optional. There are many types of signals obtained by airborne equipment, including radar, communication, electronic reconnaissance, optical and other signals. Even the same type of load receives signals that are also diverse, such as radar signals, including synthetic aperture radar signals, warning radar signals, and array radar. Signal. Different types of signal storage require different file management methods and data transmission layer algorithms, so data storage methods must be diversified and available for selection;

[0041] Second, the hardware resources invoked by data storage are configurable. Without changing the hardware resource architecture, deploy...

Abstract

The invention discloses a software-defined airborne equipment data storage method, which comprises the following steps: exposing hardware resources to an application management module to realize the resource perception of the hardware medium layer by the application layer; sending the airborne equipment data to be stored to the application Algorithm layer, the requirements of the application layer are also sent to the application algorithm layer to realize the perception of the storage data and application requirements of the application algorithm layer; perform equipment data processing based on application perception; perform file management of equipment data to be stored; Implementation of the transport layer algorithm; call the driver of the interface in the general interface layer, write the file data and data to be stored into the hardware medium; complete various data storage in the storage medium. The present invention exposes hardware resources to the application layer, fully mobilizes hardware resources at the software level to realize data storage requirements in different applications, greatly reduces the frequency of hardware update iterations, thereby reducing equipment application development time, cost, and technology risk.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a software-defined airborne equipment data storage system and storage method. Background technique [0002] The combination of equipment and aircraft can give full play to their advantages. It not only has the ability of equipment to work, but also has the advantages of strong platform mobility and easy use. It has great value in many national economic and military applications. [0003] The data rate of some airborne equipment is much higher than the data transmission rate of the wireless link, especially in remote work and application scenarios with complex terrain such as mountainous areas. Therefore, on-board data storage will be the main way to save some airborne equipment data, and it has become one of the hotspots of airborne equipment research. [0004] At present, the development of airborne equipment data storage technology is usually aimed at one or several application sce...
