Moonlet ground testing method based on virtualization computer system

Abstract

The invention provides a moonlet ground testing method based on a virtualization computer system. The moonlet ground testing method mainly relates to hardware equipment mainly comprising a virtual machine server and a mirror application terminal end and a software service mainly comprising a virtual computer and an operating system mirror. The same environment systems are needed to be built in a satellite factory testing field and an external field testing field, a factory testing system uses a database server to store satellite remote testing data and a testing result after configuration, and a mirror image is used for providing an order sending and data displaying service for a user. The database server and the mirror data are exported when being transitioned, the importing operation is actuated in the external field testing environment, the testing system formed in the external field after importation can completely copy the final state of the factory testing system, and the data can be exported again for storing or referring after the test in a launching field is ended. The method has the characteristics of being general, fast and high in reliability, the testing and maintenance cost can be lowered, the testing period of a satellite is shortened, and the workload of a testing worker is reduced.

Description

technical field [0001] The invention belongs to the field of spacecraft testing and relates to a satellite testing method. Background technique [0002] At present, most satellite ground test systems adopt a distributed structure established by physical computers, that is, each computer in the test system exists independently, and the data communication between the computers is interconnected through a switch. The software configuration of each computer etc. need to be carried out separately, even if two identical computers are configured, two operations are required, which makes the management and maintenance of the ground test system more difficult. Whenever a new satellite model is tested, the testers need to reconfigure the operating system and related software and hardware settings of each computer, and when the state of the application software version in the test system changes, the testers need to update it separately Application software installed on each computer....

AI Technical Summary

Problems solved by technology

This will inevitably cause a lot of repetitive work for testers, thus affecting the completion cycle of satellite model test tasks, and also reducing the stability and reliability of the test system

[0003] On the other hand, in this distributed structure that relies on physical computers, due to the independence of each computer, tags need to be added to distinguish different computers, and computer users can only find local documents on fixed computers

When it is necessary to learn from the test data or documents of other satellites, it is necessary to find the test computer of the corresponding satellite, which makes the document maintenance work of testers more cumbersome and increases the management cost

When performing multi-satellite test missions, the above problems become more severe due to the cross-use of satellite test files and the transmission of satellite data in the same network segment

[0004] In addition, for the conventional satellite production mode, the final stage of the satellite test cycle will be transferred from the factory test to the launch site test. The transition work of the physical computer test system needs to bring all the test computers and related equipment in the factory test process, manpower and material resources. The cost is relatively large, which increases the time cost and is not conducive to improving the test efficiency
