[0034] In some embodiments, the second camera 13 of the drowning detection device 1 uses a wide-angle camera, and multiple cameras are set according to the camera angle of the wide-angle camera to achieve more comprehensive coverage of the monitoring range. For example, a commercially available 360 ​​smart camera (product name: 360D606, JD.com product number: 2770504) can be used, which has a 140° human eye wide angle and human shape recognition function. The camera can be sprayed with waterproof spray or sealed with waterproof sealant around the camera to achieve underwater use. Figure 3 This is a bottom view of the drowning detection device 1. To achieve 360° detection angle coverage, three smart cameras with a 140° human eye wide angle can be installed under the floating block in a manner that the shooting angle covers 360° outward. There are also other wide-angle cameras in the prior art. For example, patent CN2318643Y provides a hemispherical wide-angle lens with a viewing angle of 90-140 degrees.

[0035] In some embodiments, the first camera 12 and the second camera 13 of the drowning detection device 1 can perform 360-degree rotation detection, capture human body information in the adjacent water area, and transmit the human body information to the data processing module. https: / / www.youlai.cn / yyk / article / 566498.html ), human drowning is a process, not an instantaneous event. Human drowning may take 5 to 25 minutes. The camera does not need to continuously detect the human body to detect drowning. In some scenarios, the rotation frequency of the camera can be set. For example, the camera can be set to rotate 120 to 180 degrees per minute. The camera can capture several human movements in a short period of time. In more cautious scenarios, a 360° camera with human tracking function can be used. For example, the commercially available human detection camera Huawei 360-degree waterproof camera (product name: Huawei Smart Selection Seagull, JD.com product number: 100080503550) can be used. It has a camera field of view of 360° horizontally and 125° vertically, a panoramic timed cruise function, and human detection and movement tracking functions; for example, the commercially available Newman wireless waterproof camera (product name: Newman CWY006-128, JD.com product number: 100052290722) can be used. It has a dual gimbal design and can achieve 360° tracking without blind spots.

[0036] Continue to refer Figure 1 In some embodiments, the drowning alarm device may include a first drowning alarm device 21 and a second drowning alarm device 22. The first drowning alarm device 21 may be, for example, a power amplifier speaker, a warning light, etc., which may alert the people in the swimming pool and all staff to see if there are people around them who need help. The second drowning alarm device 22 may be, for example, an alarm device for professional lifeguards, including but not limited to wireless headsets, etc., which may alert lifeguards individually and provide specific location information to lifeguards based on a pre-determined pool grid location.

[0037] refer to Figure 4 In some embodiments, such as in a swimming pool environment, the drowning detection alarm system further includes a third camera 31 and a fourth camera 32. The third camera 31 and the fourth camera 32 are traditional wall cameras that provide a global view on the water surface.

[0038] refer to Figure 5 and Figure 6 , place a drowning detection device of the present invention in the swimming pool, which can be placed in the center of the swimming pool. The drowning detection device can float in the swimming pool. For some standard swimming pools with lane lines or buoys, the drowning detection device can also be installed on the lane lines or buoys, and the floating block can be tied to the lane lines or buoys by, for example, elastic bands. If multiple drowning detection devices are used, they can be flexibly combined and used in floating or fixed ways. The drowning detection device of the present invention transmits the captured human image information to the data processing module. When person A is photographed, the drowning risk value is calculated to be low. The data processing module determines that it does not meet the drowning posture characteristics and does not trigger an alarm prompt. When person B is photographed, the drowning risk value is calculated to be high and is judged to meet the drowning posture characteristics, triggering an alarm prompt.

[0039] In some embodiments, the camera of the drowning detection alarm system disclosed in the present invention determines the characteristics of the human body's drowning posture by capturing key points of the human body, such as human facial organs, such as eyes, nose and mouth, ears, and other key points of the human body such as major body joints. After analysis by the data processing module, the human body's movement posture and its relationship with the water surface, the length of time it stays under the water surface are comprehensively confirmed, and the drowning risk value is calculated. When the drowning risk is high, an alarm is triggered to remind relevant personnel to rescue. There are many existing technologies for the recognition of human drowning posture and the triggering method of the alarm. For example, the automatic alarm method disclosed in the CN115761843A patent can also be used for drowning detection and alarm.

[0040] refer to Figure 7 In order to further improve the safety monitoring efforts, multiple drowning detection devices disclosed in the present invention can be placed in the swimming pool to more easily capture the situation of human drowning. The processing process is similar to Figure 6 Similarly, any drowning device that captures person B drowning will trigger an alarm.

[0041] refer to Figure 8 and Fig. 9 For home use, it can be used for risk detection in situations where drowning is likely to occur, such as when a child is bathing, drowsy or drunk. Considering the privacy and security of usage, this mode is limited to LAN mode only. The drowning detection alarm system determines the drowning posture, and when the main monitored person is at risk of drowning, an alarm is triggered to alert the guardian. When the drowning risk is eliminated, the drowning detection alarm system can be manually turned off.
