Embodiment Construction

[0033] Embodiments of the present invention provide a method for resisting strong electromagnetic interference, a smart door lock, and a computer storage medium to solve the technical problem in the prior art that the smart door lock is easily interfered by strong electromagnetic signals and is opened by mistake.

[0034] The technical solutions in the embodiments of the present application are to solve the above-mentioned technical problems, and the general idea is as follows:

[0035] A method for resisting strong electromagnetic interference is provided, comprising: detecting whether the voltage value of a control signal sent to a motor drive circuit of a smart door lock is greater than a preset threshold; wherein, the control signal is used to control the motor drive circuit to drive a motor in the smart door lock. The motor turns on the smart door lock; if it is, the control signal will be delayed. When the delay reaches the specified time, the currently received control s...

Abstract

A method for anti-electromagnetic interference and an intelligent lock, for use in solving the technical problem of false opening of an intelligent lock because the intelligent lock is easy to be interfered by an electromagnetic signal. The method comprises: detecting whether the voltage value of a control signal sent to the motor driving circuit (303) of an intelligent lock is greater than a preset threshold, wherein the control signal is used for controlling the motor driving circuit (303) to drive the motor (304) in the intelligent lock to open the intelligent lock; and if yes, delaying the control signal, and when the delay reaches a specified duration, sending the currently received control signal to the motor driving circuit (303), so that the motor driving circuit (303) is not controlled by the control signal within the specified duration.

Description

technical field [0001] The invention relates to the field of smart home, in particular to a method for resisting strong electromagnetic interference, an intelligent door lock and a computer storage medium. Background technique [0002] In smart homes, the use of smart door locks is becoming more and more common. By using smart door locks, users can easily open the door without carrying a key, and there is no need to configure keys due to lost keys and increased family members. Life brings great convenience. [0003] The opening of the smart door lock is usually by verifying the user's identity, such as fingerprints, and driving the motor to open the door lock. However, a "small black box" (actually a small Tesla coil, which can generate a short-term high-frequency high-voltage current to generate a strong electromagnetic interference signal) currently on the market, the strong electromagnetic interference generated by the "small black box" Interfering with the signal to in...
