Description
Technical Field
The application belongs to the field of spacecraft test authentication, and particularly relates to a satellite transmitting field test authentication service message interaction method and system.
Background
With the increasing demand and reliance on aerospace equipment by informationized warfare, I' me army is faced with the challenge of transitioning aerospace equipment from "trial" to true "equipment type". In recent years, I'm army has been exploring and trying to test and check strategies and methods that aim to enhance the ability of aerospace equipment to develop.
The method ensures that the 'good use of the satellite' is the original purpose of carrying out satellite launching field test identification during the in-orbit service period of the satellite, but traditional space equipment test identification in China is carried out after the system is launched, wherein the exposed defects are difficult to correct in the in-orbit operation of the space equipment, and meanwhile, the key decision support strength of test data and evaluation results to the mining program is weak, so that the aim of reducing the mining risk is difficult to achieve, and therefore, the method is necessary to carry out the space equipment launching field test identification as the last gateway before the satellite is launched.
The satellite transmitting field test identification work needs to acquire data from each satellite development unit, and the data formats and information interaction flows of different development units are various, so that the difficulty of satellite transmitting field test identification business transmission, acquisition and data analysis is great, and most of systems currently adopt custom application layer protocols or XML, JSON and other standard data formats to realize data analysis and transmission. The following problems exist for this type of protocol parsing in large part:
1) The custom application layer protocol is adopted: the protocol header and message body strategy is generally adopted, wherein the protocol header is a fixed boundary, the message body is a mixed code, each byte is required to be read one by one according to the agreed byte order, so that other code logic in the program is written, and as whether the spliced byte stream protocol is correct or not cannot be intuitively judged, and when the protocol is expanded or modified, both a producer and a consumer of data need to modify the program, and the workload is extremely high.
2) Protocols described using XML/JSON: the XML format has lower analysis efficiency, and XML needs to transmit marks, so that data is greatly increased compared with the custom protocol byte stream data and data in data volume, and when the transmitted data volume is large, the transmission efficiency becomes a great problem. Protocols described using JSON: the data structure is simple and support for complex data structures is limited.
3) Forward and backward compatibility is not high: when the intersystem protocol is upgraded, all relevant parts must be rewritten into the protocol analysis part, and the others cannot analyze the protocol correctly.
