Problems solved by technology

Existing technologies, such as "A Personal Eye Monitoring System" with the patent application number CN201520197620.0, mentioned judging by the intensity of ultraviolet light (UV value). In fact, in addition to sunlight in life, artificial light sources of different wavelengths also have ultraviolet light. For example, LED lights, tungsten lamps, mercury lamps, energy-saving lamps, fluorescent lamps, and halogen lamps can emit a small amount of ultraviolet rays. In addition, copier light sources, camera flashes, and insecticides can also emit high-intensity ultraviolet rays. lamps, etc., so only the measurement of ambient light ultraviolet intensity is prone to deviation, resulting in inaccurate statistical results; for example, the "Indoor and Outdoor Scene Recognition Method and System" with the patent application number of CN201410663505.6 uses the light sensor (measuring light Strong), acceleration sensor, gyroscope, magnetic sensor, air pressure sensor, temperature sensor and / or global positioning system components for indoor and outdoor determination, only used for mobile terminals, complex structure and algorithm, energy consumption is too high compared to smart wearable High; such as the "indoor and outdoor judging device and indoor and outdoor judging method" with the authorized patent number CN101924990A, using a mobile communication terminal positioning method, such as GPS for indoor and outdoor judging, also has the same problem

Abstract

The invention is applicable to the data processing and the intelligent wearable field, and provides a method and device for cooperatively determining whether a usage scene of user is indoor or outdoor through ultraviolet ray intensity and illumination intensity. The device and the method comprise: an ultraviolet ray sensor measures a surrounding ultraviolet ray intensity value; an environment light sensor measures an illumination intensity value of the surrounding environment; comparison is performed on a preset ultraviolet intensity value and a light illumination intensity high-low threshold value; and a determination about whether the user is indoor or outdoor is made. The device and method combine with user current time, a user geographic position, a local weather condition and cooperatively inquire information of sunrise and sunset time, ultraviolet intensity and illumination intensity data to perform comprehensive adjustment on the magnitude of the threshold values and further improve identification accuracy.

Description

technical field [0001] The invention belongs to the field of data processing and smart wearables, and in particular relates to a method and a device for judging whether a user's usage scene is indoors or outdoors through the cooperation of environmental ultraviolet intensity and light intensity. Background technique [0002] At present, in the field of smart wearables, for example, when it is necessary to know the device usage scenarios of teenagers, and to count the time of indoor activities and outdoor activities, it is necessary to identify and distinguish whether the user scenarios are indoors or outdoors. Existing technologies, such as "A Personal Eye Monitoring System" with the patent application number CN201520197620.0, mentioned judging by the intensity of ultraviolet light (UV value). In fact, in addition to sunlight in life, artificial light sources of different wavelengths also have ultraviolet light. For example, LED lights, tungsten lamps, mercury lamps, energ...
