Embodiment Construction

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

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

[0040] First, the data storage methods of airborne equipment are diversified and optional. There are many kinds of signals acquired by airborne equipment, including radar, communication, electronic reconnaissance, optical and other signals. Even the signals received by the same type of payload 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 can be selected;

[0041] Second, the hardware resources for data storage calls are configurable. Without changing the hardware resource architecture, the har...

Abstract

The invention discloses a software-defined airborne equipment data storage method, which comprises the following steps of: exposing hardware resources to an application management module to realize resource perception of an application layer on a hardware dielectric layer; sending to-be-stored airborne equipment data to the application algorithm layer, and application layer requirements are also sent to the application algorithm layer, so that the application algorithm layer can sense the to-be-stored data and the application requirements; performing equipment data processing based on application awareness; performing file management of the equipment to-be-stored data; implementing a transmission layer algorithm of equipment to-be-stored data; calling a driving program of an interface in the universal interface layer, and writing the file data and the to-be-stored data into a hardware medium; and storing all kinds of data in the storage medium. According to the method, hardware resources are exposed to an application layer, the hardware resources are fully transferred on a software layer to meet data storage requirements in different applications, and the hardware updating iteration frequency is greatly reduced, so that the equipment application development time is shortened, the cost is reduced, and the technical risk is reduced.

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 to work with equipment, but also has the advantages of strong platform mobility and convenient use. It has great value in many national economic and military applications. [0003] The data rate of some airborne equipment is much higher than that 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 of data storage for some airborne equipment, and it has become one of the hotspots in the research of airborne equipment. [0004] At present, the development of airborne equipment data storage technology is usually aimed at one or several application sce...
