Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical health, and particularly relates to an intelligent sunscreen bracelet system. BACKGROUND

[0002] With the improvement of people's health consciousness, the damage of ultraviolet rays to the skin has become the focus of public attention. Excessive exposure to ultraviolet rays (especially UVA and UVB) not only causes sunburn and skin aging, but also increases the risk of serious diseases such as skin cancer. Therefore, scientific and effective sunscreen measures have become the key to protecting skin health in daily outdoor activities.

[0003] However, the existing sunscreen methods still have many limitations: 1. In the traditional way, users often rely on the fixed time effect (such as the theoretical protection time corresponding to the SPF value) on the sunscreen cream package, but the actual protection effect is significantly affected by factors such as ultraviolet intensity, sweat amount, wiping, etc. The fixed time effect is difficult to reflect the real protection state, and it is easy to cause insufficient or excessive reapplication.

[0004] 2. The protection effect of physical sunscreen articles such as hats, sunscreen clothes, and umbrellas is closely related to the wearing method and coverage range, but users often have difficulty accurately judging the actual protection coverage rate of each part of the body, especially in complex environments (such as beaches and mountains), which is easy to cause protection omission.

[0005] 3. The key information such as the uniformity of sunscreen cream application and whether there are missed application parts is difficult to intuitively perceive, and users often cause an increased risk of local skin exposure due to the inability to judge the weak areas of sunscreen.

[0006] Based on this, the present application provides an intelligent sunscreen bracelet system, which can eliminate the disadvantages of the existing sunscreen technology. SUMMARY

[0011] In an optional scheme, the ultraviolet visualization and sunscreen supplement module comprises a hyperspectral probe, calibration data and an image processing algorithm, the hyperspectral probe is used for capturing the original spectrum data of the target area, and the image processing algorithm is used for carrying out wave band separation, geometric correction and reflectivity calculation on the original spectrum data, so as to identify the sunscreen type and generate a pseudo-color visual image.

[0012] In an optional scheme, the effective time calculation formula of the sunscreen timing module is: effective time = (SPF / 15) x (1 / UV index) x basic time, wherein SPF is the sunscreen SPF value input by the user, and UV index is the current UV index monitored by the ultraviolet detection module.

[0013] In an optional scheme, the physical shielding detection module comprises a YOLOv8 target detection model, an OpenCV image processing tool, a random forest classifier, and a body part coverage model, the YOLOv8 target detection model is used to detect hats, umbrellas, sunscreen clothes, glasses, and other physical sunscreen items, the random forest classifier is used to classify the environment type, and the body part coverage model is used to calculate the physical protection coverage of each part of the body.

[0014] In an optional scheme, the power management module comprises a motion sensor, and a CPU temperature monitor, the motion sensor is used to detect the user activity state, when the user inactivity duration exceeds 1 minute, the system is switched to a low-power consumption mode; when the user inactivity duration exceeds 5 minutes, the system is switched to a sleep mode; when the user activity is detected, the system is switched to a normal mode.

[0015] In an optional scheme, the risk level is divided into five levels, i.e., low, medium, high, very high, and extremely high.

[0016] Compared with the prior art, the present application has the following advantages: 1. The UV detection module provides real-time UV index and trend data, which provides a basis for the sunscreen timing module to calculate the effective time of sunscreen; the physical shielding detection module obtains the use of physical sunscreen items and the environment type, which can dynamically adjust the SPF requirement of the sunscreen timing module and the reapplication suggestion of the hyperspectral visual sunscreen reapplication module, and the three modules work together to make the sunscreen decision more suitable for the actual scene of the user and avoid the judgment deviation caused by single data.

[0018] 3. The hyperspectral visual sunscreen reapplication module visualizes the sunscreen effect through imaging technology, and combined with the risk level data of the UV detection module, can accurately mark the reapplication parts; the physical shielding detection module generates personalized suggestions according to the environment (such as beach, city) and physical protection situation (such as whether to wear a hat) of the user, and the two modules work together with the UV detection data to enable the user to not only visually see the weak sunscreen area, but also obtain a protection scheme that meets the user's own scene, thereby improving the user's sunscreen compliance.

This coordinated management not only ensures the normal functioning of the sunscreen function, but also maximizes energy consumption. BRIEF DESCRIPTION OF DRAWINGS
