Embodiment Construction
[0010] The satellite system-level anti-irradiation system and method provided by the present invention will be described in detail below in conjunction with the accompanying drawings.
[0011] refer to figure 1 , a schematic diagram of the structure of an embodiment of the satellite system-level anti-irradiation system according to the present invention, the system includes a security mode management chip 12 and a normal mode processing chip 14 arranged on the base plate 10 .
[0012] The safe mode management chip 12 is used to perform work processing in the safe mode in the satellite system mode and perform power-off and wake-up management for each component in the normal mode processing chip 14 . Among them, in the safe mode, the satellite payload or data transmission does not work and the satellite adopts a sun-oriented design.
[0013] Specifically, in the safe mode, the satellite adopts a sun-oriented design to ensure system energy; at the same time, the satellite payloa...

The invention provides a satellite system-level anti-radiation system and method. The satellite system-level anti-radiation system comprises a safe mode management chip and a normal mode processing chip which are arranged on a bottom plate. The safe mode management chip is used for conducting work processing under the safe mode in satellite system modes and conducting power outage and awakening management on all components in the normal mode processing chip. The normal mode processing chip is used for being used in cooperation with the safe mode management chip for conducting work processing under the normal mode in the satellite system modes. When payload or data transmission of a satellite does not work, the safe mode management chip conducts power outage on all the components in the normal mode processing chip, and a satellite system is in the safe mode. When the satellite needs to work, the safe mode management chip awakens all the components in the normal mode processing chip, and the satellite system is in the normal mode. Low-grade components can be adopted for part of the satellite, the cost, weight and power consumption of the satellite are reduced, and the satellite development period is shortened.
Description
technical field [0001] The invention relates to the technical field of spacecraft electronic design, in particular to a satellite system-level anti-radiation system and method. Background technique [0002] At present, in the design of spacecraft, the anti-irradiation design of components is the most concerned point in electronic design. Generally speaking, components are required to have strong anti-single event capability, especially for the main control computer. Therefore, the main control computer is required to use higher-level components. However, higher-level components are more expensive and difficult to purchase, resulting in high cost and long cycle of satellite development. [0003] Therefore, it is necessary to provide a satellite anti-irradiation method, so that the satellite can use low-grade components, reduce the cost, weight and power consumption of the satellite, and shorten the satellite development cycle. Contents of the invention [0004] The purpo...
