Description

Method for controlling intelligent door lock and intelligent door lock Technical Field The present disclosure relates to the field of intelligent devices, and more particularly, to a method for controlling an intelligent door lock and an intelligent door lock. Background With the advancement and development of technology, various kinds of intelligent devices for home and office environments have been widely integrated into the daily life of users, and these intelligent devices include, for example, intelligent door locks, intelligent curtains, intelligent doorbell, and the like. The intelligent door lock is capable of improving life convenience and intelligent level, and simultaneously, has higher requirements on stability and reliability of a power supply system. The traditional intelligent door lock is usually powered by a dry battery, and when the driving motor, the fingerprint identification module, the wireless communication module and other modules work simultaneously, an instantaneous large working current can be generated, so that the voltage at the end of the dry battery is suddenly reduced, and the problems of restarting, identification failure, abnormal action of the door lock and the like of the system are caused. In addition, the load carrying capacity of the dry cell itself is reduced with the increase of the use time. In order to meet the power supply requirements in different application scenes, a combined power supply scheme of an intelligent door lock by adopting a dry battery and an energy storage circuit is proposed in recent years. The dry battery is used as a basic power supply unit, has the advantages of simple structure, low cost, convenience in replacement and the like, and is a mainstream power supply selection of a large number of low-power-consumption intelligent devices. The energy storage circuit is an auxiliary power supply circuit capable of realizing electric energy storage and rapid charge and discharge, and can cooperate with the dry battery to improve the load carrying capacity of a power supply unit formed by the dry battery and the energy storage circuit together and prolong the service life of the dry battery. Common implementations of energy storage circuits include, but are not limited to, rechargeable lithium batteries, supercapacitors, and other combinations of energy storage elements or cells having energy storage characteristics. When the intelligent door lock is in a working state, such as a driving motor of the intelligent door lock, a fingerprint identification module and other electric loads, the dry battery and the energy storage circuit can cooperatively output electric energy to supply power for the electric loads together so as to meet the instantaneous high-current demand and avoid voltage drop, and when the intelligent door lock is in a non-working state such as standby, dormancy and locking, and the electric loads have lower power consumption, the dry battery can charge the energy storage circuit so as to supplement and store the electric energy for the next high-power work. In general, a charge start threshold voltage and a charge stop threshold voltage may be set. The charging start threshold voltage is used for controlling the time when the dry battery starts to charge the energy storage circuit, and when the terminal voltage of the energy storage circuit is reduced to the voltage value, the dry battery is controlled to start to charge the energy storage circuit. The charge stop threshold voltage is used for controlling the time when the dry battery stops charging the energy storage circuit, and when the terminal voltage of the energy storage circuit rises to the voltage value, the dry battery is controlled to stop charging the energy storage circuit. Disclosure of Invention The present disclosure provides a method for controlling an intelligent door lock and an intelligent door lock, which can identify an unlocking scene type or a prediction unlocking scene type related to a last unlocking process, and control a charging process of a dry battery to an energy storage circuit by adaptively adjusting a charging stop threshold voltage under the condition of distinguishing different unlocking scene types, so that an energy storage capacity of the energy storage circuit is matched with a power consumption requirement of a corresponding unlocking scene, and optimize energy consumption of the dry battery while guaranteeing power supply reliability, and improve overall power supply efficiency and adaptability of a combined power supply unit formed by the dry battery and the energy storage circuit. According to one aspect of the present disclosure, a method for controlling a smart door lock is provided. The intelligent door lock comprises a dry battery and a storage circuit, wherein the dry battery is used for providing electric energy. The method comprises the steps of identifying unlocking scene categories based on the last unlocking process of the intelli
