Embodiment
[0092] The present invention will be described in detail below by taking the dual redundant power distribution system of an on-orbit aircraft as an example.
[0093] The dual redundant power distribution system of the on-orbit aircraft can realize the connection control of the power distribution channel with constant power and the control of the non-constant power distribution channel according to its own timing or through the 422 serial port to receive the command sent by the ground via space-based measurement and control. On-off control.
[0094] like figure 2 As shown, the dual redundant power distribution system includes a central processing control module (including two sets of CPU processing circuits and reset circuits for master and backup), a load power supply and distribution module (including two sets of Power distribution circuit and unsteady power distribution circuit) and remote control instruction receiving module (including two sets of master and backup).
