Non-inductive backup circuit board

The invention discloses a non-inductive backup circuit board. The non-inductive backup circuit board at least comprises a detection module, a main interface module, a backup interface module, a main power supply module and a backup power supply module, wherein the detection module is respectively connected with the main interface module and the one or more backup interface modules, and the detection module is also connected with the main power supply module and the one or more backup power supply modules; the detection module is used for switching from the main interface module to the backup interface module when detecting that the main interface module is in a non-working state; and/or when it is detected that the output voltage of the main power supply module is reduced to a preset threshold value, the backup power supply module is conducted to supply power to other modules; according to the embodiment of the invention, the onboard hot standby circuit is adopted, board cards or equipment are not additionall
