Intelligent door and window opening and closing detection alarm device and detection method thereof

Abstract

The invention relates to an intelligent door and window opening and closing detection alarm device and a detection method thereof. The device comprises a shell and a detection alarm circuit arranged in the shell, the detection alarm circuit comprises a central processing unit, a door and window opening and closing detection unit and a wireless communication unit, wherein the door and window opening and closing detection unit and the wireless communication unit are connected with the central processing unit; and the door and window opening and closing detection unit adopts a six-axis sensor comprising a three-axis magnetic sensor and a three-axis acceleration sensor. The opening and closing states of the door and window are detected by collecting changes of the earth magnetic field. A single structure is adopted, the opening and closing states of the door and the window can be detected through one single component, the door opening state, the door opening angle and the door opening force can be reported to a user mobile phone or a cloud server, door opening and closing alarm, door re-opening and closing alarm and falling and prying-resistant alarm are achieved, and rain alarm can beconducted when the device is installed on a skylight. The device can be installed at any position of a door and window, the installation position and distance are not limited, misjudgment is not likely to be caused, installation and use are convenient, and the detection accuracy is high.

Description

technical field [0001] The invention relates to a door and window opening and closing detector, in particular to an intelligent door and window opening and closing detection and alarm device and a detection method thereof. Background technique [0002] With the rise of smart homes and the improvement of people's security awareness, door and window opening and closing detectors are favored by people. At present, the door and window opening and closing detectors commonly used in the market are also called door magnetic alarms. The door magnetic alarm consists of two parts, namely the switch part and the magnet part. The switch part is made of a magnetic reed switch connected by a lead wire and packaged in a final shape; the magnet part is packaged in a plastic or alloy shell by a magnet corresponding to the magnetic field strength. The switch part and the magnet part are respectively installed in the door frame (window frame) and the door leaf (window sash). When the two are ...

AI Technical Summary

Problems solved by technology

[0004] 1. Must be used in pairs: the main and auxiliary parts (switch part and magnet part) need to be used in pairs, and both are indispensable;

[0005] 2. The distance is limited: the main and auxiliary components must be installed close to each other, and the effective distance is limited. If the installation is not good, it will easily cause misjudgment, affect the detection accuracy of door and window opening and closing, and also increase the difficulty of construction;

[0006] 3. The position is limited: it can only be installed in the door frame (window frame) and door edge (window edge) area, the installation position has great limitations, and it is easy to be touched and cause falling off
