Power supply control system and method, electronic equipment and storage medium

Abstract

The power supply control system comprises a switching power supply module, a comparison module, a processor, a low-voltage control module and a linear power supply module, the switching power supply module is connected with the comparison module, the comparison module is connected with the processor, the processor is connected with the low-voltage control module, and the low-voltage control module is connected with the linear power supply module; the comparison module detects and compares voltages at two ends of the comparison module and outputs a high-level signal or a low-level signal, the processor analyzes the level signal and informs the low-voltage control module, the low-voltage control module detects the signal and controls the linear power supply module to perform circuit switching according to a signal result, and the switching power supply module supplies power to a switched and connected circuit. The invention further discloses a control method, electronic equipment and a storage medium. According to the invention, the functions of automatic adaptation and switching compatibility to different standard voltages when the multimedia equipment is electrified are realized, and compared with other prior art, the multimedia equipment has the advantages of simple structure, wide application, convenience in use and high use efficiency.

Description

technical field [0001] The present invention relates to the technical field of power supply, in particular to a power supply control system, method, electronic equipment and storage medium. Background technique [0002] At present, there are usually two types of voltages used in indoor electricity in various countries in the world, namely 100V-130V and 220V-240V. The built-in remote control or switch device realizes the function of starting and shutting down. In this process, the power supply usually only applies to one type of standard voltage. For example, the standard voltage in some foreign countries is 110V while the domestic standard voltage is 220V. When the voltage of the electrical appliance does not match the standard indoor voltage, the electrical appliance cannot be used under normal circumstances. Even if it can be used barely, the function is often greatly reduced, and it may cause damage to the electrical appliance. Therefore, it is necessary to design a syste...

[0002] At present, there are usually two types of voltages used in indoor electricity in various countries in the world, namely 100V-130V and 220V-240V. The built-in remote control or switch device realizes the function of starting and shutting down. In this process, the power supply usually only applies to one type of standard voltage. For example, the standard voltage in some foreign countries is 110V while the domestic standard voltage is 220V. When the voltage of the electrical appliance does not match the standard indoor voltage, the electrical appliance cannot be used under normal circumstances. Even if it can be used barely, the function is often greatly reduced, and it may cause damage to the electrical appliance. Therefore, it is necessary to design a system that can automatically identify and adapt to different voltages. power control system
