The present disclosure relates to security control methods and systems. The security control system may include at least one storage device storing a set of instructions; and one or more processors in communication with the at least one storage device, wherein when executing the set of instructions, the one or more processors are configured to direct the system to: obtain first data from a first device; obtain second data from a second device; associate and process the first data and/or the second data; and send the processed first data and second data to a server and/or a user terminal. The present disclosure can achieve linkage control of a plurality of access controls to meet the needs of users on indoor security.

Security control method and system

A method and a system for offline verification code generation based on a smart door lock system. The method may include in response to an unlocking event, recording, by a mobile terminal, a trigger time of the unlocking event; in response to the unlocking event, sending, by the mobile terminal, a request for unlocking verification information to a cloud server, wherein the request for the unlocking verification information is used to request the cloud server to return a verification code of a smart door lock, and the unlocking verification information includes a private key seed of the smart door lock and the trigger time; and receiving, by the mobile terminal, the verification code of the smart door lock for opening the smart door lock generated by the cloud server based on the private key seed and the trigger time.

Methods and systems for offline verification code generation based on smart door lock system

The present disclosure provides a smart door lock and a method for controlling the smart door lock. The method may be implemented on a computing apparatus including a processor and a storage device. The method may include obtaining user information and determining whether the user information passes a verification. The method may further include in response to a determination that the user information passes the verification, controlling the smart door lock to perform an unlock operation. The method may further include determining whether the door on which the smart door lock is installed has a preset action within a preset time period and in response to a determination that the door has the preset action within the preset time period, controlling at least one component of the smart door lock to perform at least one operation.

The present invention relates to a heat dissipation fan, where the heat dissipation fan includes a fan frame and a fan blade, where the fan blade includes a hub and a plurality of double-layer blades evenly disposed around the hub, and a primary air intake area is formed between the double-layer blades; the double-layer blade includes a primary blade and a secondary blade, where the secondary blade is fixed on the primary blade, and a secondary air intake area is formed between the primary blade and the secondary blade; and when the heat dissipation fan works, an airflow enters the primary air intake area and the secondary air intake area of the heat dissipation fan through an air inlet of the heat dissipation fan, and forms a first airflow in the primary air intake area and a second airflow in the secondary air intake area, and the first airflow and the second airflow flow out through an air outlet of the heat dissipation fan. In the present invention, the structure of the fan blade of the heat dissipation fan is improved, and the secondary blade is designed on the primary blade, and the secondary air intake area and the air guiding groove are further formed. In this way, air pressure and airflow aggregation are increased when the double-layer blades rotate, thereby reducing resistance on an air intake side, increasing wind pressure and reducing noise.
