Embodiment 1
[0030] Such as figure 1 Shown is a flow chart of a method for judging indoors and outdoors of a user usage scene according to an embodiment of the present invention, and the method includes the following steps:
[0031] Step S1, collect the ambient light ultraviolet intensity of the scene where the user is located, and obtain the UV index value;
[0032] Step S2, collect the light intensity of the scene where the user is located, and obtain the light intensity value;
[0033] The order of step S1 and step S2 can be exchanged;
[0034] Step S3, comparing the UV index value with the preset high and low threshold of ultraviolet intensity, and comparing the light intensity value with the preset high and low threshold of light intensity;
[0035] Step S4, if the UV index value is lower than the low threshold of ultraviolet intensity and the light intensity is lower than the low threshold of light intensity, it is determined that the user's use scene is indoors, and go to step S6;...
Embodiment 2
[0047] Such as image 3 Shown is a structural diagram of an indoor and outdoor judging device for user use scenarios according to an embodiment of the present invention, and the device includes the following units or modules:
[0048] The microprocessor system 101 includes a microprocessor, a memory 201, an input and output bus and its peripheral devices and circuits, and also includes necessary supporting devices and chips, etc., which are not limited here.
[0049] The ultraviolet sensor 102 collects the ultraviolet information of the scene where the user is, and transmits it to the microprocessor through the input and output bus of the microprocessor system 101 .
[0050] The ambient light sensor 103 collects the light intensity information of the scene where the user is located, and transmits the information to the microprocessor through the input and output bus of the microprocessor system 101 .
[0051] The microprocessor system 101 compares the UV index value obtained ...
