Distributed test control system suitable for small satellite

Abstract

The invention discloses a distributed test control system suitable for a small satellite, which comprises a message uplink communication module, a message decoding module, a message filtering module, a user authentication module, a message distribution module, a device control module, a message coding module and a message downlink communication module. The distributed test control system uses a unified test control mechanism to ensure that only one gateway is arranged between a tested object and all test systems and between a test device and all the test systems, so the distributed test control system can effectively prevent outside illegal invasions and ensure the reliability and the safety of tests; besides, the distributed test control system can realize multi-satellite parallel tests to ensure that a tester can perform test switching easily and monitor test conditions of all satellites, the test work not only can be performed on a test special network but also can be performed on a local area network even the internet so as to realize real distributed tests. By using the distributed test control system, test device resources can be allocated reasonably, and the test cost can be reduced.

Description

technical field [0001] The invention relates to a distributed testing control system suitable for small satellites, and is suitable for distributed testing of small satellites. Background technique [0002] The small satellite test has its own characteristics, that is, the test system controls the measured object through the test equipment on the one hand; on the other hand, the test system communicates with the master control server, sends remote control instructions and receives telemetry data. At present, due to safety and reliability considerations, the test of small satellites is limited to the dedicated test network, which limits the test space. The satellites to be tested are placed in the test hall, and the test instruments and equipment are placed in the electrical test room. The test satellite is connected to send test instructions and receive test data. A set of test resources can only serve the test of one satellite, and test resources and related information can...

Problems solved by technology

At present, due to safety and reliability considerations, the test of small satellites is limited to the dedicated test network, which limits the test space. The satellites to be tested are placed in the test hall, and the test instruments and equipment are placed in the electrical test room. The test satellite is connected to send test instructions and receive test data. A set of test resources can only serve the test of one satellite, and test resources and related information cannot be shared.

The traditional test structure has the following problems: First, the test cost is high, such a test structure cannot be tested in parallel, and only one satellite can be tested at a time. In order to improve the test capability, a set of test facilities and test teams have to be copied, which greatly increases the test cost; Second, automated testing technology is limited and cannot utilize ever-changing computer technologies, such as network communication, graphical monitoring, real-time early warning interpretation, remote monitoring, etc.; third, the traditional testing structure is too narrow and fixed, unable to expand, and unable to adapt to the development of satellite industrialization need
