Abstract

The invention relates to an energy saving control circuit which is used for saving electricity consumption of a power consuming device. The invention comprises a power supply circuit and a controller, wherein, the power supply circuit comprises an incoming end and a working end. The working end of the power supply circuit is connected with the controller and supplies power for the controller, a trigger circuit and a cutoff circuit are arranged between the incoming end and the working end, the cutoff circuit is connected with the controller, the trigger circuit turns on the power supply circuit for supplying power for the power consuming device, and the controller cuts off the power supply circuit through the cutoff circuit. The energy saving control circuit of the invention can realize intelligent control on power output and save energy as much as possible when meeting the working requirements of different power consuming loads.

Description

technical field [0001] The invention relates to an energy-saving circuit, in particular to an intelligent node control circuit. Background technique [0002] In order to achieve the purpose of saving electricity in some power supply circuits, some energy-saving circuits are often used, such as alarms, time-delay lights, electronic code locks, etc. [0003] A traditional power saving circuit is generally provided with a trigger conduction circuit between the input terminal and the working terminal of the power supply circuit. The trigger-on circuit typically includes a manually operated switch. After the switch is pressed, the input end and the working end are turned on, so as to supply power to the power consumption equipment of the load. The switch generally has a short-term self-locking function. After the switch is pressed, the power supply circuit will continue to be turned on for a period of time until the switch jumps to cut off the power supply circuit. [0004] Ho...
