Embodiment approach

[0039] to combine figure 1 with figure 2 As shown, according to an embodiment of the present invention, the comprehensive testing device 1 includes a transmission unit 11 and a processing unit 12 . In this embodiment, the transmission unit 11 is used to transmit data information with the spacecraft, and the processing unit 12 controls the transmission unit 11 and collects data information in the transmission unit 11 . In this embodiment, the data information includes: engineering telemetry information, digital tube telemetry information, delay telemetry information and control instructions. Engineering telemetry information, data tube telemetry information, and delay telemetry information are respectively transmitted from spacecraft A to transmission unit 11, and control instructions are transmitted from transmission unit 11 to spacecraft 1. In this embodiment, the processing unit 12 receives engineering telemetry information, digital tube telemetry information, and delay t...

Abstract

The invention relates to a spacecraft test system. The spacecraft test system comprises integral test equipment for transmitting data information with a spacecraft, intermediate service equipment fortransmitting the data information with the integral test equipment, and a client for transmitting the data information with the intermediate service equipment, wherein the intermediate service equipment serves as an information warehouse for data information transmission between other equipment. For example, the integral test equipment serves as a release end and releases classified data information to the intermediate service equipment, and the client serves as a subscription end and subscribes to data information from the intermediate service equipment. The release end and the subscription end do not need to be online simultaneously to transmit data information, the data information is transmitted asynchronously in release and subscription processes due to the intermediate service equipment, so that the release end and the subscription end do not depend on each other, and the spacecraft test system can transmit data information more reliably and flexibly.

Description

technical field [0001] The invention relates to a test system, in particular to a spacecraft test system. Background technique [0002] The spacecraft integrated test system is a large-scale distributed heterogeneous system. The real-time and reliability of test data distribution in the spacecraft integrated test system is the most fundamental guarantee of the entire integrated test system. In the current spacecraft comprehensive test system, the data transmission and processing process is complicated, which affects the transmission rate of data information. At the same time, phenomena such as data loss and disorder are prone to occur in the process of data information transmission in the prior art. [0003] As the design of spacecraft becomes more and more complex, the amount of downlink telemetry data information is increasing. When a large number of clients access data information concurrently, the existing data subscription method is prone to problems such as network c...
