Shelf interactive power control circuit

Abstract

A shelf power control circuit includes a power source, a status sensor, a status detection circuit, a switch, and a control signal detection circuit. The power source is used to supply power, and the status sensor is used to detect a status change of products on a shelf. The status detection circuit is coupled to the status sensor and the power source for generating an enabling signal when the status sensor detects the status change of the products. The switch is coupled to the power source and the status detection circuit for being turned on when receiving the enabling signal and turned off when receiving a disabling signal. The control signal detection circuit is coupled to the switch for generating the disabling signal when the control signal detection circuit is turned on.
