The invention discloses a main and standby equipment intelligent converter including a DC stabilized voltage supply, a state monitor, a single-chip microcomputer and an intermediate relay output control circuit. The DC stabilized voltage supply of the intelligent converter provides a stable working voltage for the intermediate relay output control circuit and a single-chip microcomputer circuit; an input terminal of the intermediate relay output control circuit is in series connection with an output interface of the single-chip microcomputer; an output terminal of the intermediate relay output control circuit is connected to an equipment switch circuit; the single-chip microcomputer obtains equipment fault trigger signals, timed trigger signals and power-off trigger signals in real time to control connection of different contacts of two intermediate relay output circuits so as to further control working state switching between main and standby equipment and realize fault switching, timed switching and power-off switching between the main and the standby equipment; phenomena that the main and the standby equipment can not be used due to fault and aging resulted from being unused for a long time are prevented; and normal and safe operation of the equipment are guaranteed.
