Title:
ELECTRONIC LOCK FEEDBACK CONTROL CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2022/141204
Kind Code:
A1
Abstract:
The present application provides an electronic lock feedback control circuit. In the electronic lock feedback control circuit, a thermistor in a sampling circuit is used to simulate a resistance value of an electronic lock that varies along with temperature, so as to obtain a resistance sampled value; a processor samples a supply voltage of a first power supply to obtain a voltage sampled value, controls, according to the obtained resistance and voltage sampled values, a voltage converter to convert the supply voltage of the first power supply into a voltage that varies along with the resistance value of the electronic lock, and supplies the voltage to the electronic lock for driving. Therefore, it is ensured that, even when an electronic lock is under a variable ambient temperature and/or a variable supply voltage, the current of the electronic lock is constant, and then the service life of the electronic lock is prolonged.
