Subscription method of satellite data compatible with multiple data formats

Abstract

The invention provides a subscription method of satellite data compatible with multiple data formats. The multiple data formats are characterized in that with the development of the space technology, ground communication device protocols or telemeasuring data types can change due to the change of a telemeasuring system, and the formats of different satellite test data on different platforms are diversified. The subscription method of the satellite data compatible with the multiple data formats mainly includes the steps that variable configuration content of the ground communication device protocols, the test data types and the like is stored through an extensible markup language, after the satellite test data are received, matched communication protocol templates are automatically found, analyzed and distributed to subscribers through packaging components, then a program is separated from configuration information, and the problem of inconvenience that subscription logic of the satellite data needs to be rechanged when the data formats change is solved. According to the method, the satellite test data of different formats can be compatible, subscription requests of different subscribers can be met, and subscription universality and subscription extensibility of the test data between different satellites of different models and user data customizability are achieved.

Description

technical field [0001] The invention provides a satellite data subscription method compatible with multiple data formats, belonging to the technical field of spacecraft automatic testing. Background technique [0002] On the one hand, the subscription server receives the satellite test data and analyzes the satellite test data according to the satellite ground equipment test communication protocol; on the other hand, it receives the user's satellite test data subscription request. Finally, the test data is packaged and combined to provide users with customized satellite test data for users to understand, view, and analyze the current test data and test conditions. [0003] With the continuous development of communication satellite technology, the autonomous capability of on-board information sources (subsystems or equipment) is continuously enhanced, and the data occurrence rate and packet length of generated data packets are also constantly changing. The telemetry system w...

Problems solved by technology

[0005] The purpose of the present invention is to: overcome the shortcomings of the satellite test system in the satellite test system that the subscription server parses the satellite test data and the client subscribes to the test data to operate strictly according to the code logic, and proposes a satellite data subscription method compatible with multiple data formats. Test data and client subscription test data can intelligently match XML data templates for data parsing and subscription, which completely solves the problem that subscribers rely entirely on code logic to operate, and have poor versatility, scalability, and customizability
