Problems solved by technology

[0005] Due to the use of multiple sensors, filters or spectrometers, this will increase the cost of the product, and the product is large in size and not easy to carry
The UV intelligent monitoring products on the market only provide UV index, and users do not know the radiation intensity of different bands of UV light sources, what effect it will have on the skin, when the skin will be sunburned, etc.

Embodiment 1

[0043] see figure 1 , is a flow chart of the method for monitoring the effect of ultraviolet radiation on the skin provided in this embodiment. The monitoring method comprises steps S1-S6:

[0044] S1: Set the user's skin type through the mobile terminal device, and obtain the SPF of the user's UV protection tool, and determine the corresponding UV radiation critical value Hmax through the signal analysis module according to the user's skin type and SPF.

[0045] This step is used to determine the critical value Hmax of ultraviolet radiation. Specifically, in this step, the critical value Hmax of the amount of ultraviolet radiation is determined according to the formula Hmax=MED×η, wherein: MED is the minimum radiation dose that causes erythema on the skin sample after being exposed to ultraviolet radiation for (24 ± 2) hours , η is the sun protection factor. See Table 1 for skin types and their sensitivity to UV radiation.

Embodiment 2

[0071] see Figure 5 , is a structural block diagram of the monitoring device for the influence of ultraviolet radiation on the skin provided by this embodiment. The monitoring device includes a mobile terminal device 1 , an ultraviolet sensor 2 , a control module 3 , a communication module 4 and a prompt module 5 .

[0072] The mobile terminal device 1 is used to set the user's skin type, obtain the SPF of the user's UV protection tool, and send the user's skin type and SPF to the control module 3 .

[0073] Ultraviolet sensor 2, used for real-time acquisition of ultraviolet radiation intensity and output current signal I i .

[0074] The control module 3, on the one hand, is used to receive the user's skin type, SPF, current signal I i , calculate the critical value Hmax of ultraviolet radiation, and the real-time radiation intensity E of UVA, UVB and UVC bands iUVA ,E iUVB and E iUVC , the total effective UV radiation intensity E i and ultraviolet index UVI, the radi...

Abstract

The invention discloses a method for monitoring influence of ultraviolet radiation on skin. The method comprises the following steps of S1, enabling mobile terminal equipment to set a user skin type, obtaining a sunscreen index of an anti-ultraviolet tool of a user, and enabling a signal analyzing module to determine the corresponding ultraviolet radiation quantity critical value Hmax according to the user skin type and sunscreen index; S2, enabling an ultraviolet sensor to obtain the current ultraviolet radiation intensity in real time, and output a current signal Ii, and enabling the signal analyzing module to determine the real-time radiation intensities EiUVA, EiUVB and EiUVC at the UVA, UVB and UVC wave bands according to the current signal Ii; S3, determining the total effective ultraviolet radiation intensity Ei and the ultraviolet index UVI; S4, determining the radiation dosages HUVA, HUVB and HUVC at the UVA, UVB and UVC wave bands within the preset time threshold range, and the total effective radiation dosage H. The invention also discloses a device for monitoring the influence of ultraviolet radiation on the skin. The method and the device have the advantages that the radiation intensity at different wave band of ultraviolet ray is determined, and the sunburn can be prompted.

Description

technical field [0001] The invention relates to the technical field of intelligent monitoring, in particular to a method and device for monitoring the influence of ultraviolet radiation on skin. Background technique [0002] In our daily life, we are often exposed to different sources of ultraviolet radiation, such as sunlight, artificial ultraviolet light and energy-saving lamps. After ultraviolet radiation irradiates the human body, it can cause the photochemical process and photoelectric reaction of the skin, so that the skin produces many active substances, which play a role in health care, such as improving sleep, lowering blood pressure and enhancing human immune function. However, long-term exposure to ultraviolet radiation can cause photodermatitis, sagging and aging of the skin, and even skin cancer. [0003] Different bands of ultraviolet rays have different effects on the skin. According to the wavelength, ultraviolet rays can be divided into: near ultraviolet ra...
