Problems solved by technology

[0003] Detection based on door magnetism can provide relatively accurate detection, but its installation and wiring are complicated, and the existing frame structure of the door needs to be destroyed
Although the detection based on the magnetic sensor is simple to install, it is easily affected by the environment. When it is disturbed by the external magnetic field, there will be misjudgment.
Image-based detection requires a camera, which is expensive and not applicable in dark environments

Embodiment Construction

[0028] According to various embodiments of various aspects of the present disclosure, acceleration data from a door or window is detected, and then an open or closed state of the door or window is determined based on certain morphological characteristics of the acceleration data. The angular velocity data from the door or window is further detected, and then the opening and closing state of the door or window is determined by combining the respective morphological characteristics of the acceleration data and the angular velocity data. Various embodiments of the present disclosure will be described below with reference to door open / close state detection, and it is conceivable that it can also be applied to window open / close state detection.

[0029] figure 1 A door according to one embodiment is shown. An acceleration sensor and an angular velocity sensor for detecting acceleration data and angular velocity data from the door can be installed in the door lock, preferably an in...

Abstract

Provided is a method for detecting a state of a door or window, comprising: receiving acceleration data of the door or window, the acceleration data being acquired in a direction perpendicular to a plane of the door or window; judging whether the acceleration data represents a first specific morphological feature or not, wherein the first specific morphological feature at least comprises a predetermined shape feature of a waveform of the acceleration data and a predetermined relation feature related to the acceleration data; and determining a state of the door or window based on a determination result for the acceleration data. By judging the morphological characteristics of the acceleration data, the state of the door or the window can be determined more accurately.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to the detection of doors or windows. Background technique [0002] With the progress of society, more and more detection methods are applied in our daily life to provide convenience and safety for our life, such as detecting the opening and closing status of doors. Commonly used door switch state detection includes detection based on door magnetism, detection based on magnetic sensors and detection based on images. [0003] Detection based on door magnetism can provide relatively accurate detection, but its installation and wiring are complicated, and the existing frame structure of the door needs to be destroyed. Although the detection based on the magnetic sensor is simple to install, it is easily affected by the environment. When it is disturbed by an external magnetic field, misjudgment will occur. Image-based detection requires a camera, which is expensive and not ...
