The invention relates to a power supply control module and an intelligent photon lock. The intelligent photon lock comprises a power supply, a power supply control module, an optical signal receiving module and a microprocessor module, wherein the power supply is used for providing electric energy; the power supply control module comprises a photodiode, a signal amplifier and a field-effect transistor; the photodiode is used for inducing an optical signal and generating a current signal; the signal amplifier is used for amplifying the current signal; the field-effect transistor is used for controlling on-off of the power supply according to the amplified current signal; the optical signal receiving module is used for converting the optical signal which is emitted by a photon key and contains ID number information into an electric signal; the microprocessor module is used for controlling locking and unlocking of the door lock according to the electric signal. The power supply switch is controlled by taking optical signal discharge as a trigger signal, the circuit design is reasonable, the problems that the current is high or the output voltage is instable and the like are solved, and the current consumption is reduced.
