Satellite launching site test identification service message interaction method and system

Abstract

The invention provides a satellite launching site test identification service message interaction method, which is characterized in that proto files are distributed to a test identification service system and each satellite development unit data system, and when data transmission needs to be carried out between the test identification service system and each satellite development unit data system, the proto files are sent to the test identification service system; according to the type of the to-be-transmitted data, different proto files are adopted to convert the to-be-transmitted data into a set message structure, so that the problems of various data formats, low transmission efficiency, large transmission data volume, no forward and backward compatibility and the like of satellite equipment products of different development units are solved; the data processing efficiency and stability of the satellite launch site test identification system are improved, the accuracy and efficiency of conversion are ensured, once the demand changes, the data structure can be updated without influencing the deployed program, the length of the data carried in the data message can be reduced, and the serialization and deserialization costs of the data are reduced at the same time.

Description

technical field [0001] The invention belongs to the field of spacecraft test and appraisal, and in particular relates to a method and system for exchanging business messages of test and appraisal of a satellite launch site. Background technique [0002] With the increasing demand and dependence on aerospace equipment in information warfare, our army is facing the challenge of transforming aerospace equipment from "experimental type" to real "equipment type". In recent years, our military has been exploring and trying test and assessment strategies and methods aimed at enhancing aerospace equipment development capabilities. [0003] Ensuring that satellites are "useful and functional" during their in-orbit service is the original intention of carrying out test and appraisal of satellite launch sites. However, my country's traditional aerospace equipment test and appraisal has always been carried out after the system is launched. At the same time, the test data and evaluation ...

AI Technical Summary

Problems solved by technology

[0005] 1) Adopt a custom application layer protocol: generally adopt the protocol header + message body strategy, in which the protocol header is a fixed boundary, and the message body is a mixed code. This protocol needs to read each byte one by one according to the agreed byte order, so that For the writing of other code logic in the program, because it is impossible to intuitively judge whether the spliced ​​byte stream protocol is correct, and when expanding or modifying the protocol, the producers and consumers of the data must modify the program, and the workload is huge

[0006] 2) Using the protocol described by XML / JSON: the parsing efficiency of XML format is low, and at the same time, XML needs to transmit tags, which will lead to a huge increase in the amount of data compared with custom protocol byte stream data and data. When the amount of transmitted data When it is large, the transmission efficiency becomes a big problem

Protocol described using JSON: the data structure is relatively simple, and the support for complex data structures is limited

[0007] 3) The forward and backward compatibility is not high: when the inter-system protocol is upgraded, all relevant parts must rewrite the protocol parsing part, otherwise the protocol cannot be parsed correctly
