Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
fig. 1 is a schematic diagram of a software test bed based on a software-defined satellite according to an embodiment of the present invention, as shown in fig. 1, the software test bed includes: development cloud 10, test cloud 20, instrumentation cloud 30, and service cloud 40.
The development cloud 10 is used for acquiring software to be tested uploaded by a software developer and testing the software to be tested according to a first testing mode;
the test cloud 20 is configured to obtain the software to be tested after the development cloud test, and test the software to be tested after the development cloud test according to a second test mode;
the measurement and control cloud 30 is used for acquiring software to be tested after the test cloud tests, and injecting the software to be tested to a software definition satellite;
the measurement and control cloud 30 is further configured to send the received target instruction to the software-defined satellite, and obtain target data fed back by the software-defined satellite based on the target instruction, where the target data includes at least one of: satellite data, telemetering data and data transmission data;
the service cloud 40 is configured to send the target instruction to the measurement and control cloud, so that the measurement and control cloud forwards the target instruction to the software-defined satellite, acquire the onboard data, and perform user testing on the to-be-tested software injected to the software-defined satellite based on the onboard data.
In the embodiment, the software test bed consisting of the development cloud, the test cloud, the service cloud and the measurement and control cloud is constructed to perform software test on software to be installed in the software-defined satellite, so that the technical problem that the software to be installed in the software-defined satellite is difficult to perform software test in the prior art is solved, one-stop service is provided for debugging, testing, injecting and in-orbit testing of the software to be installed on the software-defined satellite, the tight coupling relation between the satellite-borne software and a satellite platform is removed, the satellite-borne software is developed and deployed on the cloud and tested and evaluated on the cloud, and the technical effect of creating conditions for independent and continuous evolution of the satellite-borne software is achieved.
It should be noted that users of the software-defined satellite software test bed mainly include software developers, software testers, satellite users, and satellite test controllers.
In addition, it should be noted that the satellite measurement and control operator sends a remote control instruction to the measurement and control cloud, so that the software to be tested installed on the software-defined satellite is telemetered, and telemetering data and/or data transmission data fed back by the software-defined satellite are obtained.
In terms of application, data transmission is different from a traditional telemetry concept, and telemetry is engineering information such as working parameters, orbit characteristics, remote control feedback information and internal environment parameters of the spacecraft, and is an important reference for the spacecraft to maintain operation. The data transmission is different from the remote measurement, although the data transmission can also transmit engineering remote measurement information of the operation of the spacecraft, the data transmission is more often used for completing information acquired by the space operation of the spacecraft, such as measurement data of digital images, digital voice, test data of effective loads and the like, and the data are not necessary work information for maintaining the flight of the spacecraft, but are additional information acquired by the space operation of the spacecraft. The data transmission and the remote measurement are very similar from the technical implementation point of view and have no essential difference, and the data transmission and the remote measurement are a digital communication technology for transmitting information acquired by a spacecraft in a long distance and all involve the processes of source coding, code pattern conversion, modulation, channel coding, demodulation, synchronization and decoding of original information, which is the reason why people often confuse the data transmission and the remote measurement: from the above explanation of data transmission and telemetry, it can be seen that data transmission cannot be simply replaced with telemetry from an engineering application point of view.
In order to improve the test quality of the software test, the process of the software test can therefore be moved forward, i.e. the test is intervened during the user development. A developer for developing cloud-oriented software provides a set of debugging and developer self-testing environment for satellite-borne software, and the developer can complete unit testing, integration testing and configuration item testing specified by a platform on the development cloud.
The testing cloud is used for facing a software tester, a set of testing environment is provided for the satellite-borne software, and the tester completes configuration item testing and/or system testing on the testing cloud.

The service cloud is used for software-oriented users and provides a set of user test (Beta test) environment for the satellite-borne software, and the software on the service cloud refers to software running on an orbiting flight satellite and is verified by indirectly accessing the satellite through the measurement and control cloud.
The software defined satellite is used for operating the to-be-tested software injected on the measurement and control cloud based on a target instruction, so that the target data is generated and sent to the test cloud, and the target instruction comprises: the remote control instruction input by a satellite measurement and control person, the task instruction input by a satellite user and the like acquired by the service cloud.
