Description

High-speed information channel based on SRIO

Technical Field

The invention relates to the field of monitoring on-orbit healthy operation of satellites.

Background

The small satellite works in a space environment for a long time, and various space environment factors such as high-energy charged particles, the earth magnetic field, solar electromagnetic radiation and the like have influence on the health condition of the small satellite in on-orbit operation. Therefore, when the satellite operates in the orbit, the satellite in-orbit test system needs to perform in-orbit test on the satellite, and the in-orbit operation state of the satellite needs to be monitored so as to perform management control on the satellite.

The information processing unit and the data storage unit are indispensable components of the satellite on-orbit testing system, and form a high-speed information channel, and the information processing unit needs to perform fault diagnosis and related calculation of system health management on the acquired data; the data storage unit needs to construct a large-capacity storage space to store the original data and the diagnosis result.

As satellite systems have increased in computing power and design complexity, higher and higher communication rates between units within the system are required, and it is desirable to minimize the amount of software resources and time required to process the system during data transmission to perform other tasks. Therefore, in the satellite in-orbit testing system, the high-speed information channel constructed by the information processing unit and the data storage unit realizes the high-speed access of data among the units and ensures that the monitored data is processed in real time when the satellite operates in orbit.

In the design of some satellite systems, the information processing unit board card and the data storage unit board card are both realized based on a CPU + FPGA architecture, data communication is realized between the CPU and the FPGA on each board card by adopting a CPCI bus and a SpaceWire bus, and the transmission rates of the CPCI bus and the SapceWire bus are slow, so that the transmission rate on each unit board card is low, and finally, the transmission rate of a high-speed information channel formed by the information processing unit board card and the data storage unit board card is low. On the other hand, the architecture of the CPU + FPGA on each unit board also causes the problem that the board structure is responsible for and the system power is high, and if heat cannot be dissipated in time in the vacuum environment of satellite operation, potential hidden dangers may be caused to the on-orbit operation of the satellite. Therefore, the above problems need to be solved.
