Egylapkás mikroszámítógép energiatakarékos vezérlése

Since the intelligent electronic devices may be frequently carried out, the energy consumption requirements of these devices are very high, so some energy-saving control modules are often designed to increase the standby time of the intelligent electronic devices. The application of single-chip technology in energy-saving control is mainly divided into the following aspects: First, most of the intelligent electronic devices are in the light-load mode when they go out. At this time, energy-saving control is required to ensure the premise of their basic functions. to further reduce power consumption. Through the collection of data in intelligent electronic devices, the single-chip microcomputer can roughly infer that the current device is under a low load. At this time, the output of voltage and current can be reduced to achieve the purpose of energy saving; second, the single-chip microcomputer can control the rhythm of energy consumption, for example: In the Xiaomi Mi Band, the numbers of the human body's heart rate, sleep, and exercise steps are collected. After these numbers are collected, they will be stored locally, and then reported at a minute-level frequency. When the information is not reported, the device is in a state of low energy consumption. When the information is reported, there will be some consumption of network transmission. The microcontroller can control the rhythm of energy consumption, and control the wristband in a state of low energy consumption for most of the time, which can make the standby time up to more than 72 hours.
