The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Before discussing the exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as a process or method depicted as a flowchart. Although the flowcharts describe the various steps as a sequential process, many of the steps can be implemented in parallel, concurrently or concurrently. In addition, the order of the steps can be rearranged. The process may be terminated when its steps are completed, but may also have additional steps not included in the figures. The processing may correspond to methods, functions, procedures, subroutines, subroutines, and the like.

Embodiment 1

As shown in FIG. 1, a flow chart of a method for sleep monitoring includes the following steps:

Step 1: Determine whether the target object has entered the bed;

Step 2: After the occurrence of the bed-in action, it is judged whether the target object enters the sleep period, and after the target object enters the sleep period, the corresponding preset sleep-help mode is started according to different sleep quality levels.

In this embodiment, the specific implementation of determining whether the target object enters the bed in the step 1 is: acquiring body motion information and a bed body pressure signal of the target object, extracting a body motion signal amplitude from the body motion information, and according to Bed pressure signal value and body determined by body motion signal amplitude The discrete value of the amplitude of the dynamic signal determines that the target object has entered the bed. If the discrete index value and the amplitude of the bed pressure signal satisfy the bed-in condition, it is determined that the target object has entered the bed.

The bed-forming condition is specifically: the discrete index value continues to be greater than the first preset threshold to reach a first preset time; and after the first preset time, the amplitude of the bed pressure signal and the second pre- It is assumed that the difference of the threshold is in the preset fluctuation range reaches the second preset time.

In this embodiment, the specific implementation of determining whether the target object enters the sleep period in the step 2 is: extracting a body motion signal and a heart rate signal from the body motion information, when the oscillation dispersion of the body motion signal is lower than the pre- When the body motion signal dispersion threshold is set, and the heart rate variability determined according to the heart rate signal is lower than the preset heart rate variability threshold, the target object is in a sleep state. Because the target object enters the sleep period, its body motion signal and heart rate signal will also change correspondingly when it is awake. When it enters the sleep period, its body motion signal and heart rate signal will gradually stabilize and remain unchanged. . By detecting the magnitude of the change in the body motion signal and the heart rate signal of the target object, it is possible to accurately determine when the target object enters the sleep period and the sleep quality level. The sleep quality is classified according to the magnitude of the change of the body motion signal and the heart rate signal, and exemplarily, it can be classified into three levels of depth, medium, and shallow sleep.

Further, the preset sleep mode in step 2 includes one or more combinations of odor, air humidity, noise, and music adjustment in a sleeping environment. Users can make choices according to their own preferences. For example, users can sleep peacefully in the environment of aromatherapy and light music. Users who are sensitive to noise can pre-select to help sleep by eliminating noise when their sleep level is low. Wait.

Further, in step 2, after the occurrence of the bed-in action, it is determined whether the target object enters a sleep period, and after the target object enters a sleep period, the method further includes selectively controlling the doors and windows and the electrical equipment to be in a sleep state, and pre-setting each door and window and the electric appliance. The state the device is in after the target object enters the sleep period.

In this embodiment, the sleep state is a state in which each of the doors and windows and the electric device is in a state after the target object enters a sleep period.

Preferably, in the step 2, selectively controlling the door and window and the home appliance to be in a sleep state specifically includes: controlling the anti-theft door and window to close, and/or controlling the dormant type of appliance to be turned off, and/or maintaining the original state of the ventilation type door and window, and/or Or maintain the original state of the non-dormant electrical appliance, and / or control the anti-theft module is turned on. Here, the anti-theft doors and windows and ventilation doors and windows are mainly divided according to their functions. The overall principle is to properly open the doors and windows on the premise of ensuring safety; dormant and non-dormant appliances are divided according to the needs of users. The principle is that when the target object enters the sleep period, the electrical equipment that does not need to work is a dormant type device, such as a television set, a lighting lamp, etc., and the electrical appliances that need to work after the target object enters the sleep period, such as a refrigerator, an air conditioner, and an electric fan. Wait. Of course, the classification can be set according to the actual situation of the user, or can be changed according to the change of the demand, for example, due to seasonal changes, the demand for electrical appliances changes.

At this time, the user can modify the classification according to the actual situation.

Preferably, a safe sleep monitoring method of the present invention further comprises the following steps:

Step 3: detecting the environmental parameter value in the bedroom, and controlling the state of the ventilation door and window corresponding to the bedroom according to the environmental parameter value, so as to keep the environmental parameter value in the bedroom constant near the target environmental parameter value; wherein the environment Parameters include indoor noise signal values and pass Air volume, environmental parameter thresholds include indoor noise threshold and ventilation threshold.

By detecting the environmental parameter value, the environmental parameters of the indoor environment can be monitored in real time after the target object enters the sleep period, and the noise in the control room is at a low level, which is suitable for human body sleep, and prevents excessive noise in the room from affecting sleep quality. When it is detected that the noise in the room exceeds the set noise threshold, the ventilation door and window of the control bedroom are closed, and the ventilation door and window of the control bedroom are moderately opened when the outdoor noise is reduced to the set range, so that it can be controlled in the bedroom. The noise level is based on the comfort range, keeping the ventilation of the bedroom as much as possible, which effectively improves the sleeping environment in the bedroom.

Preferably, the environmental parameter value is associated with the sleep sign feature parameter of the target object, and provides a basis for subsequent setting of the sleep environment parameter adjustment. For example, in the process of monitoring the vital signs of the target object, the environmental parameters of the target object when the sleep is relatively stable are collected, and used as a reference for setting the sleep parameters.

The invention provides a sleep monitoring method, which improves the quality of sleep by monitoring the sleep quality level and the environmental parameters in the bedroom after the target object enters the sleep period, and starting the corresponding sleep mode according to the sleep quality level. By controlling the switching state of the ventilation doors and windows, the environmental parameter value in the bedroom is kept constant near the target environmental parameter value, and the sleep quality can be improved by controlling the sleeping environment.

Embodiment 2

A sleep monitoring system will be described in detail below in conjunction with FIG. 2.

As shown in FIG. 2, a schematic diagram of a sleep monitoring system includes a body motion detecting module, a bed finding module, and a main control module.

The body motion detecting module is configured to acquire body motion information and a bed body pressure signal of the target object;

The main control module is configured to determine, according to the body motion information, whether the target object enters a sleep period after the occurrence of the bed-in motion, and after the target object enters a sleep period, initiate a corresponding preset sleep-aid mode according to different sleep quality levels. .

In this embodiment, the bed-in determination module extracts the amplitude of the body motion signal from the body motion information, and judges according to the bed pressure signal value and the discrete index value of the body motion signal amplitude determined by the body motion signal amplitude. When the target object enters the bed, if the discrete index value and the amplitude of the bed pressure signal satisfy the bed entry condition, it is determined that the target object has entered the bed.

Because the target object enters the sleep period, its body motion signal and heart rate signal will also change correspondingly when awake, and wait for a period of time during sleep. After that, the body motion signal and heart rate signal will gradually stabilize and remain unchanged. By detecting the magnitude of the change of the body motion signal and the heart rate signal of the target object, it is possible to accurately determine when the target object enters the sleep period and determines the sleep quality level.

In this embodiment, the control unit classifies the doors, windows, and electrical equipment in advance, specifically including anti-theft doors and windows, ventilation doors and windows, dormant appliances, and non-dormant appliances, and sets target environmental parameters in the bedroom. Here, the anti-theft doors and windows and ventilation doors and windows are mainly divided according to their functions. The overall principle is to properly open the doors and windows on the premise of ensuring safety; dormant and non-dormant appliances are divided according to the needs of users. The principle is that when the target object enters the sleep period, the electrical equipment that does not need to work is a dormant type device, and the electrical appliance that needs to work after the target object enters the sleep period. Of course, the classification can be set according to the actual situation of the user, or can be changed according to the change of the demand, for example, due to seasonal changes, the demand for the electrical appliance changes, and the user can modify and classify according to the actual situation.

Preferably, the method further includes an environment detecting module, configured to detect an environmental parameter in the bedroom, and after the target object enters a sleep period, the main control module controls a state of the ventilation door and window to maintain an environmental parameter in the bedroom. The value is constant near the target environmental parameter value; wherein the environmental parameter includes an indoor noise signal value and a ventilation amount, and the environmental parameter threshold includes an indoor noise threshold and a ventilation threshold. By detecting the environmental parameter value, the environmental parameters of the indoor environment can be monitored in real time after the target object enters the sleep period, and the noise in the control room is at a low level, which is suitable for human body sleep, and prevents excessive noise in the room from affecting sleep quality. When it is detected that the indoor noise exceeds the set noise threshold, the ventilation door and window of the control bedroom are closed, and the ventilation door of the bedroom is controlled when the outdoor noise is reduced to the set range. The window is opened moderately, which can keep the ventilation of the bedroom as much as possible while controlling the noise level in the bedroom, and effectively improve the sleeping environment in the bedroom.

Preferably, the environment detecting module and the main control module may associate the environmental parameter value with the sleep sign feature parameter of the target object, and provide a basis for subsequent setting of the sleep environment parameter adjustment. For example, in the process of monitoring the vital signs of the target object, the main control module collects the environmental parameters when the target object is relatively stable in sleep, and serves as a reference for setting the sleep parameters.

The invention discloses a safe sleep monitoring method and system, which can automatically detect whether a target object enters a sleep state, and directly controls a door window and an electrical device to enter a sleep state after the human body enters a sleep state, so as to avoid the target subject from being non-subjective.
