Problems solved by technology

For example, the Chinese patent with application number 2016102048358 uses audio and video to detect user action feedback to detect falling asleep. This method will cause artificial interference to users.
[0006] In terms of the relationship between light and falling asleep, although there are some guiding theories, such as blue light makes people alert and dim light makes people sleepy, etc., there is no specific research plan for different individuals.

Embodiment 1

[0135] The human biological clock is the physiological and biochemical processes, morphological structures, and behaviors that change periodically in the human body with time. Such as figure 1 As shown, at 2 o'clock in the morning, people's sleep reaches the maximum depth, at 4:30 in the morning, body temperature reaches the lowest, blood pressure rises fastest at 6:45 in the morning, and the secretion of melatonin at 7:30 in the morning Stop, at 10:00 in the morning is the most clear-headed moment for people, and at 14:30 in the afternoon, people's limbs and limbs are in the best condition. At 19 o'clock, the body temperature reached its peak, and the secretion of melatonin began at 21 o'clock in the evening. According to the periodic changes of human physiological and biochemical activities, people can reasonably arrange their daily activities, so as to maximize the efficiency of work and rest, and to achieve the best physical and mental health. Among them, arranging and g...

Embodiment 2

[0239] In this example, see Figure 10 , Figure 11 As shown, an illumination detection device for an illuminated plane in a light environment is provided, which includes a light color acquisition module and a light color judgment module placed on a rotating platform,

[0240] The light color sensor in the light color acquisition module is connected to the bracket placed near the user in the scene of falling asleep through the pitch plate, the roll plate and the first connecting piece in turn. There is a base at the bottom of the bracket,

[0241] The pitch plate is connected to the roll plate through the pitch rotating shaft, and the rolling plate is connected to the first connecting piece through the rolling rotating shaft, and the first connecting piece is fixed on the bracket, and the rolling rotating shaft also providing an electrical connection channel for the pitch shaft through the second connecting piece,

[0242] The light color identification unit is configured to...

Embodiment 3

[0255] Different from Embodiment 1, in this embodiment, the duration of falling asleep is introduced into the input parameters of the nonlinear mapping.

[0256] This embodiment provides a detection system for falling asleep in a light environment, which includes:

[0257] A light color recognition unit that collects and recognizes light color parameters such as illuminance, color temperature and color of the reading surface light,

[0258] A sleep identification unit that collects and recognizes the user's eye opening value and its rate of change, duration of eye closure and its rate of change, heart rate and its rate of change, frequency of body movement and its rate of change, body temperature and its rate of change, etc.

[0259] an identification unit that collects and identifies the user's identity,

[0260] user interface elements for entering parameters and initiating operations,

[0261] Lamp groups with adjustable light properties,

[0262] A control unit connecte...

Abstract

The invention discloses a falling asleep detection system in a light environment and an illumination detection device for an illuminated plane. The system includes a light color recognition unit, a falling asleep recognition unit, a dimmable lamp group, a user interface unit and a control unit; Light and color parameters such as illuminance, color temperature, and xyz color coordinates of the color are used as input, and the change rate of the user's eye opening, eye closure duration, heart rate, body movement frequency, and body temperature obtained through data fusion and fitting Several sign parameters are used as the output, and a dynamic recursive Elman neural network is established to represent the mapping relationship between ambient light conditions and the user's sleep efficiency; the neural network is trained offline based on samples collected in various light environments, and the trained The network is used to predict the relevant parameters of the user's sleep efficiency under on-site lighting conditions online, so as to evaluate the impact of the light environment on falling asleep, and provide a basis for the search and recommendation of potential light environments with high sleep efficiency.

Description

technical field [0001] The invention relates to the field of intelligent lighting and sleep assistance, in particular to a detection system for falling asleep in a light environment and an illumination detection device for an illuminated plane. Background technique [0002] By directly measuring the electrophysiological activity of suprachiasmatic nucleus nerve cells in vivo and in vitro, scientists found that the electrophysiological activity of the suprachiasmatic nucleus (SCN) in the human body is a daily rhythmic activity with a 24-hour cycle, thus determining It is the master clock in our brain, the oscillator of the biological clock. SCN cells are mainly regulated by transcription-translation mechanism, even if these cells are isolated from the brain, the regulation mechanism is also effective. [0003] Various physiological activities of the human body are affected by the rhythm of the biological clock, including sleep. For sleep status, the current gold standard fo...
