Problems solved by technology

However, due to the majority of indoor influencing factors, ordinary infrared temperature detection and judgment methods may produce misjudgments, and at the same time, they do not have sufficient notarial power when implementing indoor smoking management

Embodiment 1

[0037] like Figure 1-Figure 4 As shown, an indoor smoking management method based on infrared monitoring includes the following steps:

[0038] Real-time infrared thermal monitoring is performed on the monitoring area, and when it is determined that there is a high temperature point higher than the preset smoking temperature point, the motion characteristics of the high temperature point in the preset smoking period are obtained, and the motion characteristics are compared with the preset smoking behavior model. In contrast, if it is determined that the motion feature conforms to the preset smoking behavior model, it is determined that the smoking fact is established and an alarm is issued.

[0039] Smoking detection is carried out in the dormitory of the campus. When setting up the monitoring environment, since it is stipulated that no camera equipment shall be installed in the dormitory, the system adopts an infrared concealed smoking detector that integrates a multi-band i...

Embodiment 2

[0055] Based on Embodiment 1, the difference from Embodiment 1 is:

[0056] Before the smoking judgment step, it also includes:

[0057] The ignition judgment triggering step is to monitor the ambient temperature within the monitoring range in real time, and trigger the ignition judgment step when it is judged that there is a temperature higher than the preset ignition temperature within the monitoring range;

[0058] In the ignition judgment and confirmation step, the ambient temperature within the monitoring range is monitored in real time within the preset ignition time, and whether there is a sudden temperature drop in the monitoring range is judged. An ignition event occurs within the monitoring range.

[0059] When it is determined that there is a high temperature point in the real-time infrared thermal monitoring picture, extract the infrared thermal monitoring picture within the preset ignition time before the moment, and obtain the highest temperature point in the in...

Embodiment 3

[0061] Based on Embodiment 1, the difference from Embodiment 1 is:

[0062] The step of judging and confirming further includes:

[0063] The smoking judgment sub-step is to judge whether the coordinates of the high temperature point at least one time are within the smoking reference area during the preset smoking period, and if it is judged that the coordinates of the high temperature point are within the smoking reference area at least one time. In the smoking reference area, it is judged whether there is a budget temperature difference between the temperature of the contour edge of the high temperature point and the temperature of the contour edge of the smoking reference area, which is set in the smoking behavior that is smoking behavior, if it is judged that the estimated temperature exists If it is poor, it is confirmed that there is a smoking incident within the monitoring range.

[0064] Further, when it is determined that there is a suspicious smoking behavior, therm...

Abstract

The invention belongs to the technical field of smoking monitoring, and particularly relates to an indoor smoking management method based on infrared monitoring. An indoor smoking management method based on infrared monitoring at least comprises the following steps: a monitoring step: monitoring the environment temperature in a monitoring range in real time; a smoking judgment step: when it is judged that a high-temperature point higher than the smoking temperature preset point exists, it is regarded that a smoking event occurs; a judgment and confirmation step: after the high-temperature point appears, continuing to execute the real-time monitoring step to obtain the movement track of the high-temperature point, carrying out re-confirmation on the smoking behavior, and after the smoking event is judged and confirmed, executing the informing step; in the informing step, an alarm is given and a smoking event is recorded. The invention discloses an indoor smoking management method based on infrared monitoring, which accurately judges the occurrence of a smoking behavior through infrared thermal detection, image analysis and behavior judgment, and carries out alarm processing in time.

Description

technical field [0001] The invention belongs to the technical field of smoking monitoring, and in particular relates to an indoor smoking management method and system based on infrared monitoring. Background technique [0002] In modern life, indoor fires often occur, some of which are caused by smoking. Especially in crowded environments such as dormitories and apartments, smoking detection equipment needs to be installed. The indoor environment can be probed, and the dangerous heat sources that may cause fire such as smoking can be found in time. [0003] With the rapid development of artificial intelligence technology, it has become a trend to use infrared thermal imaging technology to detect dangerous heat sources such as smoking. Compared with the current smoke detection of physical and chemical quantity detection, it can detect dangerous heat sources other than smoking. For example, electric water heaters, heaters, damaged electrical wiring, electric blankets, etc., c...
