Problems solved by technology

[0002] It has become common knowledge that smoking is harmful to health. At present, the detection of smoking generally uses a smoke sensor to detect the smoke generated by smoking. This method may not detect smoke when there is wind, so that the user's smoking cannot be detected, and the accuracy is poor.

no. 1 example

[0068] Based on the first embodiment of the method for detecting user smoking in the present invention, the method further includes:

[0069] Step S40, determining the object shape corresponding to the temperature information according to the detected temperature information;

[0070] When the user is smoking, the lit portion of the cigarette generally has a conical shape, or a shape similar to a cone.

[0071] In this embodiment, according to the principle of thermal imaging, the detected temperature information is imaged, and the shape of the object corresponding to the detected temperature information is determined. Of course, the temperature sensor used in this embodiment is an infrared temperature sensor, and the shape of the object emitting infrared rays can also be determined according to the detected intensity of infrared rays according to the principle of infrared life detection.

[0078] Based on the second embodiment of the method for detecting user smoking in the present invention, the method further includes:

[0079] Step S70, when the shape of the object matches the preset shape, record the duration of the shape of the object;

[0080] According to the result of step S50, when the shape of the object matches the preset shape, correspondingly record the duration of the object, when a general user smokes a cigarette, the maximum time required for smoking a cigarette can be determined , that is, the maximum time is the time from igniting a cigarette to extinguishing it under ideal conditions, and the corresponding shortest time can be the time required from igniting a cigarette to being smoked under ideal conditions, which is about a few seconds , such as 4 seconds, so that it can be determined that the time required for the user to inhale a cigarette is between a few seconds and the maximum time required for inhaling a cigarette. In specific impleme...

Abstract

The invention discloses a method for detecting user smoking. The method comprises the following steps: detecting environment information around the user through a temperature sensor in an intelligent bracelet; determining a change curve of the temperature information; if the change rule of the change curve is matched with a preset smoking change rule, determining the user smoking. The invention further discloses a device for detecting the user smoking. Through the adoption of the method and device disclosed by the invention, the accuracy of detecting smoking can be improved.

Description

technical field [0001] The invention relates to the technical field of smart devices, in particular to a method and device for detecting smoking by a user. Background technique [0002] It has become common knowledge that smoking is harmful to health. At present, the detection of smoking generally uses a smoke sensor to detect the smoke generated by smoking. This method may not detect smoke when there is wind, so that the user's smoking cannot be detected, and the accuracy is poor. Contents of the invention [0003] The main purpose of the present invention is to provide a method and device for detecting smoking of a user, aiming at improving the accuracy of detecting smoking. [0004] In order to achieve the above purpose, the present invention provides a method for detecting user smoking, the method includes the following steps: [0005] Detect the temperature information around the user through the temperature sensor set in the smart bracelet; [0006] determining a c...
