Technical Field

The application relates to the technical field of sensors, in particular to an ultraviolet light detection method and a mobile terminal.

Background

The sun is the most important ultraviolet light source in nature, and because the ozone layer exists in the atmosphere, ultraviolet light with the wavelength of less than 305nm is almost absorbed by the atmosphere, and the ultraviolet light with the wavelength of 305-400 nm irradiates the surface of the earth. Some ultraviolet rays of specific wavelengths have carcinogenic effects on human skin.

Currently, in order to detect ultraviolet light, an ultraviolet-enhanced silicon photodiode is the most common device for ultraviolet photoelectric detection. The semiconductor material in the ultraviolet enhancement type silicon photodiode has the intrinsic absorption wavelength larger than the ultraviolet region, and an optical filter is required to be added during detection, so that the detector has the problem of low detection efficiency, and is difficult to popularize in daily use due to the complex structure and higher manufacturing cost.

For convenience of description, the above-mentioned devices are collectively referred to as a mobile terminal.

The following describes embodiments of the present application in detail.

Referring to fig. 1a, fig. 1a is a schematic structural diagram of an ultraviolet sensor module disclosed in an embodiment of the present application. The ultraviolet sensor module can be applied to mobile terminals. As shown in fig. 1a, the ultraviolet sensor module 100 includes an asic chip 11, an ultraviolet sensor 12, a first communication interface 13, a detection window 15, and a light splitting device 16;

the ultraviolet light sensor 12 is configured to sense ultraviolet light in a first frequency band in an environment from the detection window 15 and generate a first analog electrical signal when the light splitting device 16 is in a first deflection angle range;

the application specific integrated circuit chip 11 is configured to convert the first analog electrical signal into a first digital signal, and determine ultraviolet light intensity of a first frequency band in an environment according to the first digital signal;

the first communication interface 13 is configured to transmit the ultraviolet light intensity of the first frequency band in the environment to other modules (e.g., a processor) of the mobile terminal.

Optionally, the ultraviolet light sensor 12 is further configured to sense ultraviolet light in a second frequency band in the environment from the detection window 15 and generate a second analog electrical signal when the light splitting device 16 is in the second deflection angle range;

the application specific integrated circuit chip 11 is configured to convert the second analog electrical signal into a second digital signal, and determine the ultraviolet light intensity of a second frequency band in the environment according to the second digital signal;

the first communication interface 13 is configured to transmit the ultraviolet light intensity of the second frequency band in the environment to other modules (e.g., a processor) of the mobile terminal.

In the embodiment of the present application, the light splitting device 16 may include a grating or a beam splitter. The light splitting device 16 can split the full-band white light into various bands of light. By adjusting the deflection angle of the light splitting device 16, the angles of the ultraviolet light of different frequency bands emitted from the light splitting device 16 can be adjusted. When the light splitting device 16 includes a grating, the light splitting device 16 may be a projection type grating.

One end of the light splitting device 16 can be movably connected to the fixed shaft, and the light splitting device 16 can rotate around the fixed shaft, so that the deflection angle of the light splitting device can be adjusted. The deflection angle of the light splitting device 16 may include an angle between the length direction of the light splitting device 16 and the fixed axis. The emission direction of the ultraviolet light in the first frequency band emitted from the light splitting device 16 and the emission direction of the ultraviolet light in the second frequency band emitted from the light splitting device 16 can be adjusted by adjusting the deflection angle of the light splitting device 16. As can be seen from fig. 1a, the deflection angle of the beam splitter 16 is α, and the outgoing light is split into two beams, one beam is the ultraviolet light in the first frequency band as shown by the solid line portion in fig. 1a, and the other beam is the ultraviolet light in the second frequency band as shown by the dotted line portion in fig. 1 a. As can be seen from fig. 1a, the ultraviolet light in the first frequency band just falls into the detection window 15, and can be detected by the ultraviolet light sensor 12; the ultraviolet light in the second frequency band does not fall into the detection window 15 and cannot be detected by the ultraviolet light sensor 12.

As can be seen from fig. 1b, the deflection angle of the beam splitter 16 is β, and the outgoing light is split into two beams, one beam is the ultraviolet light in the first frequency band as shown by the solid line portion in fig. 1b, and the other beam is the ultraviolet light in the second frequency band as shown by the dotted line portion in fig. 1 b. As can be seen from fig. 1b, the ultraviolet light in the second frequency band just falls into the detection window 15, and can be detected by the ultraviolet light sensor 12; the ultraviolet light of the first frequency band does not fall into the detection window 15 and cannot be detected by the ultraviolet light sensor 12.

In this embodiment, the ultraviolet sensor module 100 may set a deflection angle of the light splitting device 16, and when the deflection angle of the light splitting device 16 is within a first deflection angle range, the detection window 15 may capture ultraviolet light of a first frequency band in the emergent light of the light splitting device 16, and may not capture ultraviolet light of a second frequency band in the emergent light of the light splitting device 16. When the deflection angle of the light splitting device 16 is in the second deflection angle range, the detection window 15 can capture the ultraviolet light of the second frequency band in the emergent light of the light splitting device 16, and cannot capture the ultraviolet light of the first frequency band in the emergent light of the light splitting device 16.

The first deflection angle range and the second deflection angle range may be determined according to the distance between the light splitting device 16 and the detection window 15 and the size of the detection window 15. There is no overlap between the first deflection angle range and the second deflection angle range. For example, the first deflection angle may range from 75-105 degrees and the second deflection angle may range from 30-60 degrees.

The uv sensor module 100 may periodically adjust a deflection angle of the optical splitter 16, so that the uv sensor 12 may periodically detect the uv light in the first frequency band and the uv light in the second frequency band. When the ultraviolet sensor module 100 needs to detect the intensity of ultraviolet light in the first frequency band, adjusting the deflection angle of the light splitting device 16 to be within a first deflection angle range; when the ultraviolet sensor module 100 needs to detect the intensity of the ultraviolet light in the second frequency band, the deflection angle of the light splitting device 16 is adjusted to be within the second deflection angle range.

In the embodiment of the application, the ultraviolet sensor module can sense ultraviolet light of a first frequency band in an environment from the detection window to generate a first analog electric signal under the condition that the light splitting device is in a first deflection angle range; the first analog electrical signal is converted into a first digital signal, and the ultraviolet light intensity of a first frequency band in the environment is determined according to the first digital signal. The mobile terminal can detect the ultraviolet light intensity of a specific frequency band in the environment through the ultraviolet sensor module.

The ultraviolet light detection principle of the ultraviolet light sensor 12 can be explained by a band theory, a photon enters the semiconductor, electrons in a valence band in the semiconductor are absorbed and transited to a conduction band, carriers in the conduction band are increased, and an optical signal is detected through an output current signal.

The semiconductor intrinsic absorption wavelength can be calculated by the following formula:

wherein Eg represents the forbidden bandwidth of the semiconductor material with wide forbidden band in the ultraviolet light sensor, h represents Planck constant, and c represents the light speed in vacuum. Wide bandgap semiconductor materials theoretically exhibit better detection of ultraviolet light.

The ultraviolet light sensor has wide application range and has great application prospect in space detection, flame early warning, sewage detection, daily skin monitoring and the like. The ultraviolet band is 10-400 nm, wherein 10-200 nm is a vacuum ultraviolet band, and the light in this band cannot be transmitted in the air because air molecules absorb the light with this part of wavelength, and are generally used for detecting the outer space. Light with the wavelength of 200-280 nm is solar blind ultraviolet, and the part of light cannot reach the earth surface due to the absorption of an ozone layer. The absorption reaction is as follows:

O₃+hυ(200～305nm)→O₂+O^1D

O₂+O^1D+hυ(＜240nm)→O₃

ozone absorbs wavelengths less than 305nm and reacts to generate oxygen plasma and oxygen, and oxygen plasma absorb light with wavelengths less than 240nm to form ozone, and due to the presence of O3 in the atmosphere, light with a wavelength in the far ultraviolet band hardly exists on the earth's surface. The ultraviolet light detection is beneficial to better utilization of ultraviolet light by people, is used for ray detection of outer space on astronomy, can be used for missile detection on military affairs, can be used for sewage monitoring in daily life, can be used for ultraviolet radiation detection on human skin and the like.

Ultraviolet rays are abbreviated as UV. Ultraviolet light is in a spectral range of 100-420nm, and is often in contact with 250-410 nm. This length of light can be divided into 4 parts by wavelength range: UVA, UVB, UVC, UVV. UVA is 320-390 nm; UVB at 280-320 nm; UVC is below 280 nm; UVV is over 390 nm. The most common of the ultraviolet rays are the UVA band and the UVB band.

UVA wave band, wavelength 320-390nm, also known as long-wave black spot effect ultraviolet. It has strong penetrating power and can penetrate most transparent glass and plastics. The light helps to synthesize vitamin D, and has calcium absorption enhancing and antibacterial effects. More than 98% of the long-wavelength ultraviolet rays contained in sunlight can penetrate the ozone layer and cloud layer to reach the earth surface. UVA can reach the dermis of the skin to destroy elastic fibers and collagen fibers, and if the skin of a human body is exposed to ultraviolet rays in the UVA wave band for a long time, the skin of the human body can be tanned.

The UVB band, wavelength 280-320nm, is also called medium wave erythema effect ultraviolet. The medium penetrating power, the shorter wavelength part of which is absorbed by the transparent glass, the most part of the medium ultraviolet rays contained in sunlight are absorbed by the ozone layer, less than 2% of which can reach the earth's surface, and the medium penetrating power is particularly strong in summer and afternoon. The long-term or excessive irradiation of UVB ultraviolet rays can cause the skin to be sunburned and cause red swelling and desquamation, and the UVB ultraviolet rays have carcinogenicity on the skin of a human body and are also one of the causes of cataract of the human body. The ultraviolet health-care lamp and the plant growth lamp are made of special purple-transmitting glass (light with the wavelength of less than 254nm is not transmitted) and fluorescent powder with the peak value near 300 nm.

In the embodiment of the present application, the incident light may be full-band sunlight and may include ultraviolet light. Wherein, the first band ultraviolet light can be ultraviolet light in UVA band (wavelength is 320-390 nm). The ultraviolet light in the second frequency range can be ultraviolet light in the UVB band (with the wavelength of 280-320 nm).

Alternatively, the ultraviolet light in the second frequency band may be ultraviolet light in the UVA band (wavelength of 320-390 nm). The first band of ultraviolet light may be ultraviolet light in the UVB band (wavelength of 280-320 nm).

Wherein the beam splitting means 16 comprises a beam splitter or a grating. The light splitting device 16 can split the full-band white light into various bands of light. By setting the parameters of the light splitting device 16, the angles of the ultraviolet light of different frequency bands emitted from the light splitting device 16 can be adjusted. The light splitting device 16 may inject light of a UVA band of the incident light (e.g., white light) into the first detection window 151 and light of a UVB band of the incident light (e.g., white light) into the second detection window 152.

The ultraviolet sensor module 100 can operate in any one of a first detection mode, a second detection mode, and a third detection mode.

As shown in fig. 2a, when the ultraviolet sensor module 100 operates in the third detection mode, the first light-shielding sheet 17 covers the first detection window 151, and the second light-shielding sheet 18 covers the second detection window 152. Neither the first detection window 151 nor the second detection window 152 can detect incident light, and the ultraviolet sensor module 100 is in the sleep mode.

As shown in fig. 2b, when the ultraviolet sensor module 100 operates in the first detection mode, the second light-shielding sheet 18 covers the second detection window 152, and the first light-shielding sheet 17 does not cover the first detection window 151. The uv sensor module 100 can detect the intensity of the first band uv light decomposed by the light splitting device 16 through the first detection window 151.

As shown in fig. 2c, when the ultraviolet sensor module 100 operates in the second detection mode, the first light-shielding sheet 17 covers the first detection window 151, and the second light-shielding sheet 18 does not cover the second detection window 152. The uv sensor module 100 can detect the intensity of the uv light in the second frequency band decomposed by the light splitting device 16 through the second detection window 152.

The ultraviolet sensor module 100 may alternately operate in the first detection mode and the second detection mode (for example, switching the detection mode once every second, switching from the first detection mode to the second detection mode, or switching from the second detection mode to the first detection mode) in a time division multiplexing manner, so that the first frequency band ultraviolet intensity and the second frequency band ultraviolet intensity of the incident light may be continuously detected. When the first band ultraviolet light is ultraviolet light in UVA band (wavelength of 320-390nm) and the second band ultraviolet light is ultraviolet light in UVB band (wavelength of 280-320nm), the ultraviolet light in the two bands can be detected respectively.

The ultraviolet sensor module 100 can also selectively operate in a first detection mode or a second detection mode, and is used for detecting ultraviolet light in a specific waveband, so as to provide refined health services.

The embodiment of the application can realize the detection of the ultraviolet light intensity of a specific frequency band, thereby providing ultraviolet light reference suggestions for terminal users based on the detected ultraviolet light intensities of different frequency bands. For example, when the ultraviolet light intensity of the UVB band is detected to be weak (for example, the ultraviolet light intensity of the UVB band is less than 10 mW/square meter) and the ultraviolet light intensity of the UVA band is detected to be strong (for example, the ultraviolet light intensity of the UVA band is greater than 100 mW/square meter), the user can be reminded to get out of the sun and promote the synthesis of vitamin D and the absorption of calcium. For another example, when the ultraviolet light intensity of the UVB band is detected to be strong (for example, the ultraviolet light intensity of the UVB band is greater than 100 mW/square meter), the user can be reminded not to go out and take care of sun protection. For another example, the mobile terminal may also recommend the type of sunscreen applied by the user according to the detected ultraviolet light intensity in the UVA band and the detected ultraviolet light intensity in the UVB band (the type of sunscreen may include sunscreen absorbing the UVA band and sunscreen absorbing the UVB band) and the usage amount of sunscreen, and may also recommend a corresponding brand of sunscreen according to the recommended type of sunscreen applied.

The first communication interface 13 may include an I2C module 131, a serial data line (SDA) pin, and a Serial Clock Line (SCL) pin. When the SCL pin is high and the SDA pin transitions from high to low, the first communication interface 13 starts to transmit data. When the SCL pin is high and the SDA pin transitions from low to high, the first communication interface 13 ends transmitting data. The I2C module 131 may be used to control when the first communication interface 13 transfers data and when to end the transfer of data.

Alternatively, as shown in fig. 1c, 2b, 2c, and 2d, the asic chip 11 may include an Analog Multiplexer (AMUX) 111, an analog-to-digital converter (ADC)112, a filter 113, a digital sequence and logic control (dco) 114, and a register 115.

Wherein the analog multiplexer 111 may be used to receive the analog electrical signal transmitted by the ultraviolet light sensor 12. The analog multiplexer 111 recognizes the analog electrical signal and determines whether the analog electrical signal is a valid analog electrical signal. If so, the analog multiplexer 111 sends the analog electrical signal to the analog-to-digital converter 112. The analog-to-digital converter 112 converts the analog electrical signal to a digital signal. The filter 113 is a digital filter and is configured to filter the digital signal to obtain a filtered digital signal. The digital sequence and logic control circuit 114 is configured to analyze the filtered digital signal, determine an ambient ultraviolet light intensity value of the corresponding first frequency band or second frequency band, and store the ambient ultraviolet light intensity value in the register 115. The first communication interface 13 may obtain the environmental ultraviolet light intensity value from the register 115, and send the environmental ultraviolet light intensity value to other devices in communication connection with the ultraviolet sensor module 100.

First radiation-protective layer 33 is primarily intended to absorb ultraviolet radiation in a first frequency band (e.g., the UVA band) and second radiation-protective layer 34 is primarily intended to absorb and reflect ultraviolet radiation in a second frequency band (e.g., the UVB band). When the intelligent radiation-proof garment 300 is simultaneously provided with the first radiation-proof layer 33 and the second radiation-proof layer 33, the radiation-proof effect is best.

If the first radiation protection layer 33 is in a contracted state and the second radiation protection layer 34 is in a contracted state, the intelligent radiation protection garment 300 is in the first state, the intelligent radiation protection garment 300 mainly absorbs ultraviolet rays through a common fabric layer, and the ultraviolet radiation protection capability is weakest.

If it is detected that the intensity of the ambient ultraviolet light in the first frequency band (for example, the UVA frequency band) is less than or equal to the first threshold, the intensity of the ambient ultraviolet light in the second frequency band (for example, the UVB frequency band) is less than or equal to the second threshold, and the intelligent radiation-proof suit 300 is not in the first state, the intelligent radiation-proof suit 300 is switched to the first state.
