Control circuit of intelligent cabinet, control method of control circuit and intelligent cabinet

The invention provides a control circuit of an intelligent cabinet, a control method of the control circuit and the intelligent cabinet. The control circuit comprises a power supply end, a switch power supply circuit, an electric lock circuit and a controller. The electric lock circuit comprises an electric lock switch, an in-cabinet functional circuit and a switching circuit. The controller comprises a detection port and a power supply control port. The controller is used for detecting an electric signal of the electric lock circuit through the detection port, responding to an opening instruction for indicating opening of the cabinet door of the cabinet cell, and controlling the power supply switch to be switched on through the power supply control port, so that the electric lock switch is communicated with the power supply end to open the cabinet door of the cabinet cell; and when the electric signal of the detection port is detected to indicate that the cabinet door is closed, the power supply switch is co
