The invention provides a self-protection intelligent sensor power supply management circuit which is a high quality factor power supply management circuit, has the advantages of high output power and energy harvesting efficiency, and can drive an electronic load to normally work. The self-protection intelligent sensor power supply management circuit provided by the invention comprises a coil transducer and a power supply management circuit. The self-protection intelligent sensor power supply management circuit is structurally characterized in that a space electromagnetic field sends alternating electromagnetic field energy to the coil transducer; the coil transducer converts the electromagnetic field energy into power, and transmits the power to an up-conversion matching circuit; the up-conversion matching circuit is connected with a power storage circuit; the power storage circuit and a control circuit are connected with each other, and are finally connected with a voltage regulation output circuit; the control circuit switches on the voltage regulation output circuit to enable a super capacitor to discharge; the power is transmitted to temperature and current sensors, and a wireless transceiver node is driven to work; a PC is connected with a master node for data processing and displaying; and real-time power utilization monitoring is realized.
