Step 202, acceleration data of the wearable device is detected through the acceleration sensor.
The acceleration data may indicate how fast the speed of the wearable device changes. In practical applications, the wearable device is subjected to acceleration caused by gravity in a spatial environment, and the inclination angle of the wearable device relative to the horizontal plane can be calculated according to the acceleration. The wearable device is provided with an acceleration sensor for detecting acceleration data of the wearable device.
Optionally, the electronic device may detect acceleration data of the wearable device through the acceleration sensor when receiving the ultraviolet detection instruction; the ultraviolet detection instruction may be generated by a user by pressing a button of the wearable device, touching a control on a display screen of the wearable device, or converting according to detected voice information, or may be generated by the wearable device when determining that the current time, the ambient brightness, or the geographic location, and the like, satisfy the corresponding ultraviolet detection condition.
And 204, determining a target UV sensor according to the acceleration data, wherein the target UV sensor is one of the first UV sensor and the second UV sensor.
The target UV sensor is a UV sensor determined to detect ultraviolet rays, and the wearable device may select one of the first UV sensor and the second UV sensor as the target UV sensor according to the acceleration data. Specifically, the wearable device is generally exposed to ultraviolet radiation in a space environment due to sunlight, the wearable device can analyze one side of the first side and the second side, which is exposed to a larger sunlight radiation area, according to the acceleration data, and the UV sensor corresponding to the side, which is exposed to the larger sunlight radiation area, is determined as the target UV sensor. Namely, the side corresponding to the target UV sensor is the side with larger radiation area of the wearable device.
Optionally, it may be determined according to the irradiation direction of the sunlight that the altitude corresponding to the side of the wearable device that is exposed to a larger area of the sunlight is generally higher than the other side, and the wearable device may also analyze the altitudes of the first side and the second side according to the acceleration data, and use the UV sensor corresponding to the side with the higher altitude as the target UV sensor.
In one embodiment, the wearable device may further preset an acceleration interval when the first UV sensor is used as a target sensor, and if the currently detected acceleration data is located in the acceleration interval, the first UV sensor is used as the target UV sensor; optionally, if the currently detected acceleration data is not within the acceleration interval, the second UV sensor is taken as the target UV sensor. The preset acceleration interval may be determined according to a direction of the acceleration sensor in the wearable device relative to the gravitational acceleration, which is not limited herein.
And step 206, detecting the ultraviolet index of the environment where the wearable device is located through the target UV sensor.
The uv index is used to characterize the level of exposure to solar uv radiation. Generally, a higher uv index indicates a greater radiation intensity and greater damage to the skin and eyes of the human body. The wearable device detects the ultraviolet index of the environment where the wearable device is located through the target UV sensor. Specifically, the UV sensor may convert the received ultraviolet signal into a measurable electrical signal by using the photosensitive element, and the ultraviolet index of the environment where the wearable device is located may be determined according to the magnitude of the electrical signal.
The wearable device may output the detected ultraviolet index. Optionally, the wearable device may output indication information of different degrees according to the size of the ultraviolet index. For example, when the ultraviolet index is in the interval of 0-4, a pop-up window with green background color is adopted to display the ultraviolet index; when the ultraviolet index is in the interval of 4-6, displaying the ultraviolet index by adopting a pop-up window with yellow background color; and when the ultraviolet index is more than 6, displaying the ultraviolet index and the like by using a pop-up window with red background color. Optionally, the wearable device may also output the ultraviolet index by using voice information with different volumes, or voice information with different repetition times, or the like.
In one embodiment, the wearable device is preset with an index threshold, and the wearable device may output the indication information when determining that the detected ultraviolet index exceeds the index threshold. Wherein, the index threshold value is the ultraviolet index corresponding to the condition that the skin or eyes of the human body are injured.
According to the embodiment of the application, the acceleration data of the wearable device can be detected through the acceleration sensor, one of the first UV sensor and the second UV sensor is selected as the target UV sensor according to the acceleration data, and the ultraviolet index of the environment where the wearable device is located is detected through the target UV sensor. Because wearable equipment is equipped with two UV sensors, can select one of them as target UV sensor according to acceleration data, carry out the detection of ultraviolet index according to target UV sensor, can improve the accuracy that ultraviolet detected.
In one embodiment, step 204 of the provided ultraviolet detection method may include: acquiring a first data interval corresponding to the first side face and a second data interval corresponding to the second side face, wherein the data interval of the first data interval in the gravity direction is opposite to the data interval of the second data interval in the gravity direction; when the acceleration data are in a first data interval, taking the first UV sensor as a target UV sensor; and when the acceleration data is in a second data interval, taking the second UV sensor as a target UV sensor.
The acceleration sensor may be configured to detect acceleration data of the wearable device in a direction of gravity and two horizontal directions perpendicular to each other. Optionally, the first data interval and the second data interval that the wearable device may preset may include acceleration data intervals in three directions, respectively; in some embodiments, the first data interval and the second data interval may also include only the acceleration data interval in the gravity direction. The data interval of the first data interval in the gravity direction is opposite to the data interval of the second data interval in the gravity direction. For example, when the data interval of the first data interval in the gravity direction is less than-9.8, the data interval of the second data interval in the gravity direction may be greater than 9.8.
The first data interval and the second data interval may be set before the wearable device leaves a factory, or may be determined by guiding a user to perform gravity detection on the wearable device. Specifically, when the acceleration data is in the first data interval, the distance between the first side surface of the wearable device and the ground is greater than the distance between the second side surface of the wearable device and the ground; when the acceleration data is in the second data interval, the distance between the second side face of the wearable device and the ground is larger than the distance between the first side face of the wearable device and the ground.
Fig. 3(a) is a schematic diagram of a wearable device in one embodiment. As shown in fig. 3(a), the body of the wearable device includes a first side 310 and a second side 320; when the wearable device is placed as shown in fig. 3(a), the gravity direction is the Z axis, and two horizontal directions perpendicular to each other are respectively used as the X axis and the Y axis to establish a coordinate system; at this time, the acceleration data corresponding to the wearable device is (0,0, 9.8), the distance between the first side surface 310 and the ground is greater than the distance between the second side surface 320, and the first UV sensor provided on the first side surface 310 may be used as the target UV sensor; when the wearable device is placed as in fig. 3(b), the acceleration data corresponding to the wearable device is (0,0, -9.8), and the wearable device may use the second UV sensor provided on the second side 320 as the target UV sensor.
By acquiring a first data interval corresponding to the first side face and a second data interval corresponding to the second side face, when the acceleration data is in the first data interval, the first UV sensor is used as the target UV sensor, and when the acceleration data is in the second data interval, the second UV sensor is used as the target UV sensor, so that the accuracy of the target UV sensor can be improved.

The wearable device is placed horizontally, that is, the distance between the first side surface and the ground is equal to the distance between the second side surface and the ground, and the accuracy of ultraviolet detection of the first UV sensor and the second UV sensor cannot be determined at this time. Wearable equipment can be when being in the horizontal placement state, detects the ultraviolet index of environment in place respectively through first UV sensor and second UV sensor simultaneously to the biggest ultraviolet index in two ultraviolet indexes that the output obtained can improve the accuracy of ultraviolet index.
In an embodiment, before performing step 202, the provided ultraviolet detection method may further include: detecting the ambient light brightness of the environment where the wearable equipment is located; when the ambient light brightness exceeds the brightness threshold, the operation of detecting the acceleration data of the wearable device through the acceleration sensor is executed.
The wearable device detects the ambient light brightness of the environment, and specifically, the wearable device may include a brightness sensor, and the brightness sensor may convert the received light signal into a corresponding electrical signal according to the brightness of the received light signal, so as to obtain the ambient light brightness. The wearable device has a large difference between the indoor ambient light brightness and the outdoor ambient light brightness. The brightness threshold may be determined according to the ambient light brightness detected by the wearable device in a low-light environment, and is used for distinguishing an indoor environment or an outdoor lighting environment. Typically, the ambient light level of a wearable device in a room is often in the range of hundreds to 2000 lux; and the ambient light brightness under outdoor illumination is often more than 2000lux, even can reach tens of thousands lux. The brightness threshold may be 2000lux, 3000lux, 4000lux, etc., without limitation.
When the ambient light brightness exceeds the brightness threshold, the wearable device is considered to be possibly irradiated by sunlight, and the wearable device can detect acceleration data of the wearable device through an acceleration sensor to determine that a target UV sensor performs ultraviolet detection; alternatively, when the ambient light level does not exceed the brightness threshold, the wearable device may be deemed not to be illuminated by sunlight, and the wearable device may not perform ultraviolet detection.
Through the environment luminance that acquires wearable equipment environment, when environment luminance surpassed the luminance threshold value, then through acceleration sensor detection wearable equipment's acceleration data to confirm that target UV sensor carries out ultraviolet ray and detect, can realize ultraviolet intelligent detection, do not need user manual start, and can reduce the consumption.
In an embodiment, before performing step 202, the method for detecting ultraviolet light may further include: acquiring the current moment of the wearable device; when the current moment is within the first period, the operation of detecting the acceleration data of the wearable device through the acceleration sensor is executed.
The first time interval is the time interval corresponding to the day. For example, the first period may be 5 hours to 18 hours, 6 hours to 19 hours, 5 hours to 30 minutes to 18 hours and 30 minutes, and the like, which is not limited herein. The first period of time may be a preset period of time of the wearable device. Optionally, in an embodiment, the wearable device may also locate current location information, obtain sunrise time and sunset time corresponding to the current location information, and determine a period between the sunrise time and the sunset time as the first period.
The wearable device can detect whether the current moment is in the first time period or not in real time, and when the current moment is determined to be in the first time period, acceleration data of the wearable device are detected through the acceleration sensor so as to determine that the target UV sensor performs ultraviolet detection.
Wearable equipment can not receive the sunlight irradiation when night, and wearable equipment can not carry out ultraviolet ray detection. Through the present moment who obtains wearable equipment, when being in first period at the present moment, then carry out ultraviolet ray and detect, can realize ultraviolet intelligent detection to reduce the consumption.

step 402, obtaining a current moment of the wearable device.
And step 404, detecting the ambient light brightness of the environment where the wearable device is located when the current time is within the first time period.

FIG. 5 is a flow chart of detecting UV index in one embodiment. In one embodiment, the process of detecting the ultraviolet index of the environment where the wearable device is located by the target UV sensor in the provided ultraviolet detection method may further include:
step 502, determining a target second time interval to which the current time belongs from a plurality of second time intervals divided by the first time interval.
The first period may be divided into a plurality of second periods, such as two, 3, 4, etc., which are not limited herein. For example, the first time period is 6 hours to 18 hours, and the second time period may be 6 hours to 9 hours, 9 hours to 14 hours, 14 hours to 18 hours, etc., which are not limited herein. Generally, the intensity of the ultraviolet light radiated by the sunlight is different in the different second periods. The wearable device may determine a target second period to which the current time belongs from a plurality of second periods divided by the first period.
Step 504, according to the association relationship between the preset second time period and the frequency, a target frequency corresponding to the target second time period is obtained.
Frequency refers to the frequency at which the wearable device detects the ultraviolet index through the target UV sensor. The wearable device is preset with an association relationship between the second time period and the frequency. Generally, the ultraviolet intensity of the midday radiation is higher than the ultraviolet intensity of other times, and in the preset association relationship between the second time period and the frequency of the wearable device, the closer the second time period is to the midday, the higher the corresponding frequency is. For example, when the second period is 7 to 10, the corresponding frequency may be 3 times per hour; when the second period is 10 to 14, the corresponding frequency may be 6 times per hour; when the second period is 14 to 19, the corresponding frequency may be 2 times per hour, etc., and is not limited herein.
The wearable device may obtain a target frequency corresponding to the target second time period according to an association relationship between the preset second time period and the frequency.
And step 506, detecting the ultraviolet index of the environment where the wearable device is located according to the target frequency through the target UV sensor.
The wearable device can detect the ultraviolet index of the environment where the wearable device is located through the target UV sensor according to the target frequency.
Optionally, the wearable device may further re-determine the target UV sensor according to the target frequency, that is, detect acceleration data of the wearable device according to the target frequency through the acceleration sensor, to determine the target UV sensor according to the acceleration data, and detect an ultraviolet index of an environment where the wearable device is located through the target UV sensor.

In one embodiment, the process of detecting the ultraviolet index of the environment where the wearable device is located by the target UV sensor in the provided ultraviolet detection method may further include: when the current moment is not within the target time period, detecting the ultraviolet index of the environment where the wearable device is located through a target UV sensor according to a first frequency, wherein the first time period comprises the target time period; when the current moment is within the target time period, detecting the ultraviolet index of the environment where the wearable equipment is located through the target UV sensor according to the second frequency; the second frequency is greater than the first frequency, and the ultraviolet detection can be carried out by adopting higher frequency in a target time period, so that the timeliness of the ultraviolet detection can be improved. Wherein, the target time interval corresponds to the time interval with larger ultraviolet radiation intensity. For example, the target period may be 10 hours to 15 hours, 11 hours to 14 hours, 9 hours to 30 minutes to 16 hours, etc., without limitation.
In one embodiment, after detecting the ultraviolet index of the wearable device environment by the target UV sensor in the provided ultraviolet detection method, the method may further include: when the ultraviolet index is greater than or equal to the index threshold, determining the ultraviolet level corresponding to the ultraviolet index; and outputting protection information corresponding to the ultraviolet level.
The index threshold is an ultraviolet index corresponding to the condition that the skin or eyes of a human body are at risk of injury. That is, it is considered that when the ultraviolet index is smaller than the ultraviolet threshold, the human body is not damaged by the ultraviolet radiation. The ultraviolet index can be divided into different grades, and the damage intensity of the different grades to human bodies is different. The wearable device can preset protection information corresponding to different ultraviolet levels, and outputs corresponding protection information according to the ultraviolet level corresponding to the currently detected ultraviolet index. For example, when the ultraviolet level is low, the corresponding protection information may need to wear sun caps and sunglasses, apply sunscreen lotion, etc.; when the ultraviolet level is higher, the corresponding protection information can be that long-sleeve clothes are worn or shade needs to be found. Optionally, the wearable device may also output protection information including parameters of the sunscreen that needs to be applied according to the ultraviolet level.
FIG. 6 is a graph illustrating UV dose versus sunburn time for one embodiment. As shown in fig. 6, the uv index is low between 3 and 4, which causes less damage to the human body; the UV index is of the medium magnitude between 4 and 6, and the sunburn time limit is 20 minutes. The wearable device may preset protection information corresponding to different ultraviolet levels provided in the map. When the ultraviolet index detected by the wearable device is larger than or equal to the index threshold, the protection information corresponding to the ultraviolet level to which the ultraviolet index belongs is output, and the effectiveness of information reminding can be achieved.
