Embodiment Construction

[0062] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0063] The method for storage and replay of massive, diversified and complex spacecraft simulation data provided by this application can be applied to such figure 1 shown in the application environment. Among them, the data sender 102 communicates with the data receiver 104 through the network. The data receiver stores the data and then performs simulation. The data sender encapsulates the data reported by the complex spacecraft, and divides the data into low-frequency data and high-frequency data by adding data type fields; the data receiver receives the encapsulated dat...

Abstract

The invention relates to a mass diversified complex spacecraft simulation data storage and recovery method and device, a computer device and a storage medium. The method comprises the steps of packaging and analyzing simulation data reported by a complex spacecraft, storing high-frequency data of the spacecraft into a file system in a data segmentation compression storage mode, meanwhile, storing low-frequency data into a relational database and performing index optimization. A convenient query mode is provided while the data integrity is ensured, and important support is provided for later data sequential reading; for synchronous reading of the simulation data, the time accuracy of the recovery data is met to the maximum extent through a recovery pushing mode based on low-frequency data pre-reading and high-frequency data caching, and data support is provided for recovery; for the visual recovery of the data, on the basis of segmented compression and storage of the data, the performance and the effect of foreground display of the data are ensured through a data compression mode of feature value positioning and data screening.

Description

technical field [0001] The present application relates to the technical field of data storage replay, in particular to a storage replay method, device, computer equipment and storage medium for massive, diversified and complex spacecraft simulation data. Background technique [0002] The complex spacecraft simulation system needs to use multiple types of spacecraft equipment, and report multiple types of impulse, report and other data. Analyze key events, key messages, etc. to evaluate the simulation effect. On the one hand, different systems and different types of equipment bring diversified replay data types, and the replay data of different spacecraft are also different; on the other hand, due to the high frequency of spacecraft data generation and the large size of a single piece of data , bringing the challenge of mass data transmission and storage. [0003] In the prior art, there is no method for storing and rediscovering massive multivariate data for complex spacec...
