Abstract

The invention relates to a low-power-consumption control circuit and intelligent equipment. The control circuit comprises an MCU, an activation module which is used for activating the MCU according to a trigger signal, and enabling the MCU to be powered on and started, a control module which is used for keeping the MCU and a power supply battery conductively connected after the MCU is activated, and a transaction category judgment module which is used for acquiring the level of a test point and judging the category of a transaction to be processed according to the level of the test point, so as to make the MCU execute the processing flow of the transaction to be processed of the category; the test point corresponds to a trigger signal; and the control module is also used for cutting off the power supply of the MCU when the MCU is idle, so that the MCU is powered down. According to the low-power-consumption control circuit and intelligent equipment of the invention, the activation module triggered by hardware is adopted to activate the MCU, so that the MCU is electrified and started, and the corresponding processing flow is executed according to the judged category of the transaction to be processed; and when the MCU is idle, the power supply of the MCU is cut off, so that the purpose of ultra-low power consumption is achieved.

Description

technical field [0001] The invention relates to the technical field of low power consumption circuit control, in particular to a low power consumption control circuit and an intelligent device. Background technique [0002] At present, in water supply, gas supply, heating and other industries, under normal circumstances, relevant smart devices are powered by mains power. When the mains power supply is abnormal, smart devices in water, gas and heating industries cannot obtain mains power. In the case of power supply, only the battery can be used as the power supply to power the smart device. Due to the limited battery capacity, low-power design principles must be adopted during the development of smart devices. The usual low-power design method for smart devices is to first select a low-power or even ultra-low-power MCU (Micro Controller Unit, micro control unit), add low-power design of peripheral circuits, and then cooperate with program design to make smart devices The d...
