Title:
ANTI-REVERSE HOT STANDBY CIRCUIT AND ANTI-REVERSE CONNECTION METHOD FOR LOW-POWER CONSUMPTION SMART LOCK AND SMART DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/000967
Kind Code:
A1
Abstract:
An anti-reverse hot standby circuit and an anti-reverse connection method for a low-power consumption smart lock and a smart device. The device comprises a power supply circuit (100), a power supply switching control circuit (200), and an anti-reverse connection circuit (300). The power supply circuit (100) comprises a main battery power supply, a backup battery power supply and a power supply output terminal. The power supply switching control circuit (200) is connected to the power supply circuit (100) and the anti-reverse connection circuit (300), and the power supply switching control circuit (200) is used to switch the main battery power supply and/or the backup battery power supply. The anti-reverse connection circuit (300) is connected to the power supply circuit (100) and the power supply switching control circuit (200). By means of configuring the anti-reverse connection circuit (300), damage to a chip and a module caused by reverse voltage when a power supply is connected in reverse can be effectively avoided; furthermore, by means of configuring the main battery power supply, the backup battery power supply, and the power supply switching circuit, the stability and anti-interference capability of the low-power consumption smart lock are improved.
