Problems solved by technology

However, the universe is full of high-energy particles, and the impact of high-energy particles can easily cause single-event flipping or single-event latching in the on-board computer.
Once the single event flip phenomenon or single event latch phenomenon occurs, data processing errors will occur in the on-board computer, and the ground station will lose the ability to correctly implement satellite control or star affairs management

Embodiment Construction

[0008] The specific implementation manners provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0009] Such as figure 1 As shown in the schematic structural diagram of a spaceborne computer provided by the specific embodiment of the present invention, a spaceborne computer includes a central processing unit 2, a monitor 3, and a memory 1. The onboard computer also includes a low dropout linear regulator 4. The low-dropout linear regulator 4 is arranged between the central processing unit 2 and the memory 1.

[0010] The central processing unit 2 reads the machine code from the memory 1 and performs verification. If the central processing unit 2 checks the machine code and finds an error in the machine code in the memory 1, then the central processing unit 2 linearly stabilizes the voltage The device 4 issues a clear memory instruction. After the low-dropout linear regulator 4 receives the clear memory instruction sent ...

Abstract

The invention relates to a spaceborne computer, which comprises a central processing unit, a monitor and a memory, wherein a low-voltage-differential linear voltage stabilizer is arranged between the central processing unit and the memory; the central processing unit controls a reset circuit of the memory through the low-voltage-differential linear voltage stabilizer arranged between the central processing unit and the memory; if the central processing unit detects that the memory generates the single particle turning, the low-voltage-differential linear voltage stabilizer arranged between the central processing unit and the memory re-electrifies the memory.

Description

Technical field [0001] The invention relates to a spaceborne computer. Background technique [0002] The onboard computer is used to control satellites or manage satellite affairs. Only when the on-board computer processes the data correctly can it ensure the correct implementation of satellite control or satellite management. However, the universe is full of high-energy particles, and the impact of high-energy particles can easily cause a single-event flipping phenomenon or a single-event latch-up phenomenon in a spaceborne computer. Once single event flipping or single event latching occurs, data processing errors will occur on the on-board computer, and the ground station will lose the ability to properly implement satellite control or satellite management. For this reason, on-board computers must have the ability to deal with radiation interference. Summary of the invention [0003] In order to enable the on-board computer to adapt to the working environment of the universe...
