Abstract

The invention provides an SRIO protocol-based data storage and rapid downloading method, which comprises the steps of demand analysis and system architecture design, system hardware design, SRIO to storage protocol logic design and software design, and mainly comprises the functions of high-speed data storage and data playback when a system works. During data storage, high-speed load data is received through an optical fiber SRIO and stored in a solid-state storage medium, the data storage process comprises operations of data analysis, packaging, disk writing, data maintenance and the like, data acquisition and packaging are completed by data management logic, and disk writing and data maintenance are completed by data management software. According to the SRIO protocol-based data storageand rapid downloading method provided by the invention, the distance constraint of load electric signal transmission capability on a load source end and recording equipment in traditional equipment iseliminated, the limitation on the concentrated volume and power consumption of an airborne platform can be effectively reduced, and the data transmission rate and the platform adaptability are improved; and the design performance optimization of a machine-mounted platform is facilitated.

Description

technical field [0001] The invention relates to the technical field of airborne storage data transmission, in particular to a storage data and fast download method based on the SRIO protocol. Background technique [0002] Data storage products are widely used in airborne mission system products. Early products are mainly used for monitoring and recording flight parameters and bus data, with low data rate and small recording capacity. With the improvement of the performance of airborne products and the improvement of various indicators of load equipment, the types of load processed by storage products gradually include multiple load images, reconnaissance videos, etc., and the amount of data is also increasing. The distances are far apart, and the payload data transmission interface standards are different. How to realize the unified recording management of multiple types and different speed payload data and support fast playback is a new challenge for recording products. ...
