The invention relates to a power supply module which comprises an inductance circuit, a switch circuit, a check driving circuit and a controller, wherein the inductance circuit is provided with an inductor and a voltage feedback line, and the voltage feedback line feeds back the end voltage of the inductor. The switch circuit is electrically connected with the inductance circuit to drive the inductance circuit. The check driving circuit is electrically connected with the switch circuit and the voltage feedback line, and the check driving circuit controls the switch circuit and generates a current feedback signal according to the end voltage of the inductor. The controller is electrically connected with the check driving circuit, and controls the check driving circuit according to the current feedback signal.

The invention discloses a consumer automatic locking method based on automobile 4S store intelligent sales. The consumer automatic locking method comprises the steps that a 4S store controller is combined with a face camera and a face recognition and proofreading module to carry out face collection and locking on a consumer; an entrance guard worker terminal builds and supplements consumer files entering the 4S store; consumption data are supplemented and shared on a consumer terminal by a consumer; the stay area of the consumer in the 4S store is monitored by adopting an area identification module and an area monitoring camera; and the server is used for formulating consumer purchase track information. The method has the advantages that through the steps, the identity of the consumer is automatically recognized and locked, the purchase intention of the consumer is quickly known, and intelligent recommendation and automobile sales are achieved.
