The invention relates to a power interface protection circuit based on state sensing. The power interface protection circuit comprises a state sensing control module and a switch control circuit, the state sensing control module is used for sensing the separation state of the I-level and the II-level of the carrier, so that the power management of equipment in the I-level of the carrier is realized through the switch control circuit; before the I-II level separation of the carrier, the equipment in the I level is powered by the carrier main system, and after the I-II level separation of the carrier, the equipment in the I level is powered by the control subsystem. According to the design idea of the power interface protection circuit design based on state perception, a subsystem time sequence control module is utilized, a main system power supply line and a subsystem power supply line are subjected to time-sharing control through two sets of control switches, power is sequentially supplied to equipment 1, and
