Title:
POWER SUPPLY PROTECTION METHOD, AND SYSTEM WITH POWER SUPPLY PROTECTION FUNCTION
Document Type and Number:
WIPO Patent Application WO/2021/007682
Kind Code:
A1
Abstract:
A power supply protection method, and a system with a power supply protection function. The system comprises: a transmitting-receiving unit (106) and an abnormality detection unit (1022), wherein the transmitting-receiving unit (106) receives measurement information in various parameters for an electronic device in a working state, and the measurement information is obtained, by means of the transmitting-receiving unit (106), from a sensor located in at least one of a power supply side apparatus and a load side apparatus of the electronic device; and the abnormality detection unit (1022) detects, by means of respectively comparing the measurement information received by the transmitting-receiving unit (106) with corresponding threshold values and according to a comparison result, whether an abnormality occurs in the electronic device, and generates, in the case where it is detected that an abnormality occurs in the electronic device, corresponding power supply abnormality information to indicate that there is a power supply abnormality phenomenon related to at least one parameter of at least two parameters in the electronic device. The present method and system can comprehensively and accurately determine a power supply abnormality of the system, and can provide power supply protection more accurately, such that the system of the electronic device keeps running without shutting down in scenarios of a low temperature, a low voltage, a high current, etc.
