Intelligent door lock system based on microwave sensing, and microwave sensing control method

Abstract

The invention discloses an intelligent door lock system based on microwave sensing. The intelligent door lock system comprises a control unit, a microwave radar sensing module and a door lock response module used for executing a door lock function; both the control unit and the microwave radar sensing module are arranged in the body of the door lock; the antenna of the microwave radar sensing module is used as a detection point; the control unit is separately electrically connected with the microwave radar sensing module and the door lock response module; the microwave radar sensing module is used for transmitting a microwave radar signal and receiving a microwave radar echo signal reflected by a human body; the control unit is used for computing a distance between the human body and the detection point according to the difference between the transmission time and receiving time of the microwave radar signal, and the control unit is used for comparing the distance value with a preset distance value, and emits a corresponding control signal to control and on and off of the door lock response module according to a judgment result. The invention also discloses a microwave sensing control method of the intelligent door lock system based on microwave sensing. The invention can detect the human body of the close user to automatically awaken the intelligent door lock, so that the operation and consumed time are saved.

Description

technical field [0001] The invention relates to a control technology of an intelligent door lock, in particular to an intelligent door lock system based on microwave induction and a microwave induction control method. Background technique [0002] With the development of smart homes and smart appliances, smart door locks have become a must-have smart security device in the market, and intelligence and humanization have gradually become the goals pursued by people. At present, smart door locks are equipped with a sleep function in order to meet energy-saving requirements. That is, if there is no user operation on the smart door lock within the set time, the smart door lock will automatically enter the sleep state under the preset control of the controller. Cut off to avoid power consumption. The smart door lock in the sleep state is more energy-saving, and the sleep current can reach below 50μA. Based on this, when you need to use the smart door lock, you need to wake up the...
