[0061] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0062] like Figures 1 to 3 As shown, an embodiment of the present invention provides a combined smart bed 100, which includes a bed frame 10, a lighting module 20, a pressure detection module 30 and a control module 40. The bed frame 10 is provided with at least one bed board 11, and the lighting module 20 is arranged on the bed frame 10; the pressure detection module 30 is arranged on the bed board 11, and the pressure detection module 30 is used to collect pressure parameters on the bed board 11; the control module 40, the pressure detection module 30 and the lighting module 20 are electrically connected, and the control module 40 is used to receive and analyze and process the pressure parameters collected by the pressure detection module 30, and control the lighting module 20 to emit lights of different colors.

[0063] The number of bed boards 11 in the combined smart bed 100 provided in the embodiment of the present invention is variable, that is, the number of bed boards can be selected as needed. For example, the bed board can be set to one, and the bed board 11 is usually set in the middle and upper part of the bed frame 10 to ensure that the sleeping area of ​​the monitored person is in a relatively high position, which is convenient for getting on and off the bed; sufficient space can also be provided under the bed board 11, which can be used for storage or placing a desk. When the bed boards 11 are set to two, the two bed boards 11 can be stacked on the bed frame 10, which can be used by multiple users at the same time.

[0064] Of course, in some embodiments, the stacking mode between the two bed boards 11 can also be designed to be adjustable, that is, the user can adjust the distance between the two bed boards 11 as needed. For example, when more storage space is needed, the lower bed board 11 can be raised; and when more sleeping space is needed, the lower bed board 11 can be lowered.

[0065] In addition, one or both of the two bed boards 11 can also be designed as areas with other functions. For example, the upper bed board 11 can be used as a sleeping area, while the lower bed board 11 can be designed as a sofa, a rest area or an entertainment area. The bed frame in the combined smart bed provided by the present invention can be formed by splicing steel pipes, which is not only easy to install, but also can reduce costs.

[0066] It should be noted that the light module 20 in the combined smart bed provided by the present invention can emit full-color light, which not only has the basic lighting function, but also can provide sufficient light for the guardian at night to enable him to clearly see the surrounding environment. More importantly, it can also automatically adjust and emit different colors of light according to the status and needs of the guardian, thereby providing a personalized experience for the user.

[0067] Among them, the lighting module 20 can emit sleep-aiding light, which is set to warm light, such as soft yellow or orange, and can gradually reduce the brightness until it is turned off, thereby creating a warm and comfortable atmosphere, helping the ward to relax and help the ward to fall asleep quickly.

[0068] Moreover, the light module 20 can also emit a wake-up light, which is set to a cool light, such as fresh blue or white, and can gradually increase the brightness, so as to simulate the natural light in the morning, gradually wake up the biological clock of the person being supervised, so that the person can wake up naturally in the early morning. Compared with the traditional alarm clock, the use of the wake-up light is softer and more natural, and is not likely to cause sudden disturbance and discomfort, which helps the person being supervised to greet the new day with a more pleasant mood.

[0069] Furthermore, the light module 20 can also emit a warning light, which is set to red light, so as to have a strong visual impact and quickly attract the attention of the person being supervised in an emergency. For example, when the pressure detection module 30 detects that the pressure parameter on the bed board 11 is an illegal intruder, the light module 20 will emit a warning light to attract the attention of people around and warn the illegal intruder that their behavior has been detected.

[0070] In the present application, the pressure detection module 30 in the combined intelligent bed includes a plurality of pressure sensors 31, which can be distributed in an array on the bed board 11 to collect the pressure parameters borne by the bed board 11, and convert these pressure parameters into electrical signals and transmit them to the control module 40. The control module 40 can receive the data from the pressure detection module 30, and analyze it using a preset operation model, and then control the lighting module or other modules to perform corresponding actions.

[0071] The control module 40 provided in the embodiment of the present invention can determine the person who applies pressure on the bed board according to the pressure parameters collected by the pressure detection module and the preset program settings; if the person who applies pressure on the bed board is an illegal intruder, the control module will control the light module 20 to emit a warning light to warn the illegal intruder, thereby not only protecting the privacy and security of the person under guardianship, but also effectively preventing any potential unsafe incidents from occurring. If the control module determines that the person on the bed board is a person under guardianship, the control module 40 will continue to monitor the sleeping state of the person under guardianship and adjust the light emitted by the light module to provide a more comfortable sleeping environment.

[0072] To sum up, the combined intelligent bed 100 provided in the embodiment of the present invention can realize comprehensive monitoring and intelligent management of the sleep state of the monitored person through the close cooperation of the pressure detection module 30, the control module 40 and the lighting module 20. It can not only provide a more comfortable and safe sleeping environment, but also respond in time in emergency situations to ensure the health and safety of the monitored person.

[0073] In some embodiments, the control module 40 may further include a cloud server, that is, the pressure data collected by the pressure monitoring module 30 may be transmitted to the cloud server, and then the cloud server controls the lighting module or other modules to perform corresponding actions.

[0074] In some embodiments, the combined smart bed 100 also includes a communication module and a management and control terminal. The lighting module 20, the pressure detection module 30, the control module 40, the communication module and the management and control terminal are electrically connected to realize information interaction.

[0075] Specifically, the lighting module 20, the pressure detection module 30, the control module 40, the communication module and the management and control terminal are closely connected through electrical connections to form an efficient information interaction network. Among them, the communication module is responsible for establishing and maintaining the communication connection between the smart bed and the external device or network. Through the communication module, the smart bed can transmit various data and information to the management and control terminal in real time, and can also receive instructions and control signals from the management and control terminal. This two-way communication capability makes the smart bed more flexible and scalable.

[0076] The management and control terminal is the interface for the manager to interact with the smart bed. It can be a smart phone, tablet computer, server or other device. The manager can view the real-time status of the smart bed, adjust the settings of the lighting module 20, receive the pressure parameters of the pressure detection module 30, and send control instructions to the control module 40 through the management and control terminal. The design of the management and control terminal allows users to easily manage and control the various functions of the smart bed, providing a more convenient and personalized user experience. For example, when the pressure data collected by the pressure monitoring module does not change for a long time, the control module can transmit the pressure data to the management and control terminal to remind the manager.

[0077] In some embodiments, the combined smart bed 100 also includes a smart screen module 50, which is disposed on the bed frame 10. The smart screen module 50 is used to display the sleep parameters analyzed by the control module 40 and / or play video data and / or display the information sent by the management and control terminal, providing a more intuitive and convenient interactive experience for the monitored person.

[0078] In this embodiment, the smart screen module 50 may include a liquid crystal display screen, which is a multifunctional display platform in the smart bed system, and can display the sleep parameters analyzed by the control module 40 in real time. These sleep parameters may include the sleep duration, sleep depth, number of turns, heart rate, breathing rate, etc. of the monitored person, and are intuitively displayed to the user in the form of charts, curves, etc. The monitored person can understand his or her sleep status through these data, and thus adjust his or her living habits or take corresponding measures to improve sleep quality.

[0079] Secondly, the Zhihui Screen module 50 also supports the playback of video data, which means that the guardian can watch movies, TV programs or teaching videos in bed, which provides great convenience for the guardian's leisure and learning, allowing the user to enjoy a cinema-like viewing experience in bed.

[0080] Finally, the smart screen module 50 can also display information sent by the management and control terminal. As an interface for managers to interact with the smart bed, the management and control terminal can send various instructions and information to the control module 40. After processing, these information can be displayed to the person being cared for in the form of text, images, etc. through the smart screen module 50. For example, the manager can set an alarm through the management and control terminal, and the smart screen module 50 will display a reminder message when the alarm time arrives; or the manager can send health advice through the management and control terminal, and the smart screen module 50 will display the corresponding advice content based on the user's sleep parameters.

[0081] Furthermore, the bed frame 10 includes a first side panel 12 and a second side panel 13, the first side panel 12 and the second side panel 13 are arranged at both ends of the bed board 11, the first side panel 12 and the second side panel 13 are relatively arranged along the length direction of the bed board 11, and the Zhihui screen module 50 is arranged on the first side panel 12 or the second side panel 13, thereby providing a more comfortable and convenient viewing experience.

[0082] Furthermore, the bed frame 10 also includes a third side panel 14, and the third side panel 14 is arranged on one of the two sides of the bed board 11 in the width direction. The lighting module 20 is arranged on the third side panel 14, so that the light can directly shine on the bed board 11, providing the user with soft and comfortable light at night, and creating a more ideal sleeping environment for the user.

[0083] In this embodiment, the first side panel 12 and the second side panel 13 are configured as wood grain panels, which not only add a warm and comfortable atmosphere to the space with their natural texture and color, but are also favored for their durability and easy cleaning. The third side panel 14 is configured as a wood grain perforated panel, which not only retains the natural beauty of the wood grain, but also brings more possibilities and changes to the space through its unique hole design.

[0084] Furthermore, the third side panel is also provided with a socket 15 and a touch switch 17, and the touch switch 17 can be used to turn on or off the light module 20. The light module 20 includes a reading light and a smart light strip. In other words, the light module 20 can be easily controlled through a simple touch operation, so that the guardian can adjust the brightness and color of the light at any time according to his or her own preferences and needs to create a different atmosphere.

[0085] Furthermore, the combined smart bed 100 further includes an up-and-down ladder 18, which is used for a user on the upper bed board 11 to easily get on and off. It should be noted that the position of the up-and-down ladder 18 can be set as needed, for example, the up-and-down ladder 18 can be set on the left or right side of the bed frame 10.

[0086] In some embodiments, the combined smart bed 100 further includes a desk, which is arranged below and / or to the side of the bed board 11. When one bed board 11 is arranged on the bed frame 10, the desk can be arranged below the bed board 11, and when two bed boards 11 are arranged on the bed frame 10, the desk can be arranged to the side of the bed board 11, thereby having a high degree of flexibility and adaptability, and can be adjusted and changed according to different usage scenarios. Whether it is used by one person or two people, whether it needs to rest or needs to work or study, the combined smart bed 100 provided in the embodiment of the present invention can meet the needs and bring a more convenient and comfortable life experience.

[0087] In some embodiments, the modular smart bed 100 may further include an environment monitoring module, which is electrically connected to the control module 40 and is used to monitor the environment parameters of the person being cared for and send the environment parameters to the control module. The environment monitoring module may include a time sensor, which can accurately collect the light intensity and current time information in the environment.

[0088] When the environment monitoring module obtains the time information, the time information can be passed to the control module 40, and the control module 40 can compare the time information with the preset sleep mode or schedule to determine whether the monitored person is currently in the sleep period. If so, the smart bed will adjust the light color and brightness of its light module 20 accordingly to create a warm and peaceful sleeping environment for the user. For example, at night, the light module 20 will automatically switch to a soft warm color and reduce the brightness to help the user enter a deep sleep state faster.

[0089] In the combined smart bed provided in the embodiment of the present invention, the control module may include a processing unit and a storage unit. The storage unit may be configured to store computer programs and / or modules, and the processing unit implements various functions by running or executing the computer programs and / or modules stored in the storage unit and calling the data stored in the storage unit. The storage unit may mainly include a program storage area and a data storage area.

[0090] The program storage area may store an operating system, an application required for at least one function, etc. In addition, the storage unit may include a high-speed random access storage unit, and may also include a non-volatile storage unit, such as a hard disk, a memory, a plug-in hard disk, a smart memory card (Smart Media Card, SMC), a secure digital (Secure Digital, SD) card, a flash card (Flash Card), at least one disk storage unit, a flash memory device, or other volatile solid-state storage units.

[0091] The processing unit can be a central processing unit (CPU), or other general processing units, digital signal processing units (DSP), application specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general processing unit can be a microprocessing unit or any conventional processing unit. The processing unit is the control center of the modular smart bed, and uses various interfaces and lines to connect the various parts of the entire device.

[0092] like Figure 4 , Figure 5 and Figure 6 As shown, in an embodiment of the present invention, a smart bed sleep monitoring method is also provided, which can be applied to the above-mentioned combined smart bed, and the smart bed sleep monitoring method can be stored in the storage unit of the control module. In other words, the above-mentioned combined smart bed can realize various functions in the smart bed sleep monitoring method.

[0093] like Figure 4 As shown, the smart bed sleep monitoring method provided by the embodiment of the present invention includes the following steps:

[0094] S10, obtaining the pressure parameters borne by the smart bed, and calculating the pressure score corresponding to the pressure parameters. That is, by processing the pressure parameters to obtain the pressure score corresponding to the pressure parameters, the pressure parameters can be uniformly processed to form a unified demarcation standard.

[0095] S20, if the pressure score is greater than the pressure threshold, the smart bed is in an occupied state;

[0096] That is to say, when the pressure score is greater than the pressure threshold, it means that someone is lying on the smart bed, and the smart bed is in an occupied state.

[0097] S30, when the smart bed is in an occupied state and the smart bed is in a normal mode, obtaining the environment time of the smart bed.

[0098] The smart bed provided in the embodiment of the present invention has a normal operation mode and an alert operation mode. In this step, when the smart bed is in a state of being occupied, it is determined whether the smart bed is in a normal operation mode; if the smart bed is in a normal operation mode, the environment time of the smart bed is obtained, so that only the sleep of the person being monitored can be monitored, and more accurate sleep data and personalized services can be provided.

[0099] S40, determining whether the environment meets the preset time, wherein the preset time includes sleeping time and waking time.

[0100] S50, if the environment time meets the sleep time, start the sleep-aiding light;

[0101] S60: If the environment time meets the waking time, start the wake-up light, wherein the sleep-aiding light and the wake-up light are lights of different colors.

[0102] In steps S40 to S60, after the current environment time is obtained, the environment time can be compared with the sleep time and the wake-up time. If the current environment time matches the sleep time, the sleep-aiding light will be activated, that is, the control module can control the light module to emit the sleep-aiding light. The sleep-aiding light can be set to warm light, such as warm yellow, warm white, etc., to create a comfortable and peaceful sleeping atmosphere. Among them, the brightness of the sleep-aiding light can gradually decrease over time until it is completely turned off.

[0103] If the current environment time matches the wake-up time, the wake-up light is activated. The wake-up light can be set to a cool color light, such as cool white, light blue, etc., so that the guardian can be quickly awakened. The wake-up light can gradually increase in brightness over time until it is basically consistent with the external sunlight, thereby simulating the natural light in the morning and gradually awakening the guardian's biological clock, so that the guardian can wake up naturally in the early morning.

[0104] In summary, the smart bed sleep monitoring method provided in the embodiment of the present invention can be applied to the combined smart bed provided in the above embodiment, can monitor and analyze the status of the smart bed in real time, can create a comfortable and quiet sleeping environment, and help users better control their own sleep rhythm, and provide personalized sleep services for the monitored person.

[0105] In some embodiments, the step of obtaining the pressure parameter borne by the smart bed and calculating the pressure score corresponding to the pressure parameter comprises the following steps:

[0106] Obtaining pressure parameters borne by the smart bed, and calculating a pressure constant corresponding to the pressure parameters;

[0107] According to a preset pressure score algorithm, obtaining a pressure score corresponding to the pressure constant;

[0108] The stress score algorithm may be set as follows:

[0109] Where: X scroe is the pressure fraction; X is the pressure constant; X min is the minimum constant value; X range is the constant fluctuation value; the constant fluctuation value is the constant maximum value minus the constant minimum value.

[0110] In the above steps, the pressure parameter can be set to pressure voltage. That is, the pressure voltage change data of the sensor on the smart bed after being subjected to pressure is obtained, and a pressure vector set V is formed, wherein the pressure vector set V contains the changes of multiple sensors at this time point; the pressure vector set V is summed up to obtain the pressure constant X, and all elements in the set V are aggregated and run, simplifying the multi-dimensional pressure data into an easy-to-process pressure constant X;

[0111] Then, the pressure score corresponding to the pressure constant X is calculated through the pressure score algorithm. The pressure score can more intuitively reflect the pressure state on the smart bed, achieve standardized processing, make comparisons between different time periods more convenient, and provide a more objective and accurate pressure assessment.

[0112] It should be noted that the minimum constant X′ min , constant fluctuation value X r ' ange It can be preset as needed, and can also be dynamically adjusted according to the pressure parameters of the monitored person over a period of time, so that the sleep state of the monitored person can be monitored more accurately.

[0113] like Figure 5 As shown, in one embodiment of the present invention, the smart bed sleep monitoring method has a calibration procedure for the pressure score algorithm so that the constant minimum value X′ min , constant fluctuation value X r ' ange The pressure parameters of the monitored person are dynamically adjusted over a period of time. That is, the smart bed sleep monitoring method also includes the steps of:

[0114] S11, constructing a pressure constant set based on the pressure parameters in the T time period before the current time;

[0115] S12, calculating the coefficient of variation corresponding to the set of pressure constants;

[0116] S13, determining whether the coefficient of variation is greater than a coefficient threshold;

[0117] S14, when the coefficient of variation is greater than the coefficient threshold, the maximum value and the minimum value of the constant within the time period T are recorded and stored;

[0118] S15: Calibrate the pressure score algorithm according to the maximum constant value and the minimum constant value.

[0119] Furthermore, the smart bed sleep monitoring method also includes the steps of:

[0120] S16: If the coefficient of variation is less than or equal to the coefficient threshold, the calibration is terminated and step S11 is executed to implement the next calibration.

[0121] Specifically, the pressure parameters carried by the smart bed can be obtained to obtain the pressure parameters in the time period T, and the pressure vectors V1, V2,,,, V n , n is a different time point; the above pressure vectors are summed to obtain the sum constant data X1', X'2,,,, X' n ; Perform low-pass filtering on the above-mentioned sum constant set to obtain filtering constant data X1", X'2',,,, X' n '; Get the minimum value X in the filter constant data" min ; Standardize the filter constant data to obtain a set of pressure constants. The standardization process can be set as: X = X' n '-X' min .

[0122] Then, according to the coefficient of variation calculation formula, calculate the coefficient of variation corresponding to X; if the corresponding coefficients of variation in the T time period are all greater than the coefficient threshold, it means that the smart bed in the T time period is in an occupied state and an unoccupied state, and the maximum value and the minimum value of the constant in the T time period can be recorded and stored; if the corresponding coefficient of variation in the T time period is less than or equal to the coefficient threshold, it means that the smart bed in the T time period is only in an occupied state or an unoccupied state, and the calibration needs to be terminated; then execute the step again to construct a pressure constant set based on the pressure parameters in the T time period before the current time for the next calibration, so that the sleep state of the monitored person can be monitored more accurately.

[0123] In some embodiments, the smart bed sleep monitoring method also includes an intrusion monitoring program, so as to protect the privacy and security of the person being monitored and effectively prevent any potential unsafe incidents from occurring. That is, the smart bed sleep monitoring method also includes the steps of:

[0124] When the smart bed is in the alert operation mode, if the pressure score is greater than the pressure threshold, the smart bed is in an invaded state and the warning light is activated.

[0125] This step can be understood as: the smart bed can be set to the alert operation mode. When the smart bed is in the alert operation mode, when the pressure score is greater than the pressure threshold, it can be considered that the person being cared for on the smart bed is not the user of the smart bed, but an intruder. The warning light can be activated to remind the intruder to leave as soon as possible.

[0126] In some embodiments, when the smart bed is in an invaded state, the occurrence time of the invaded state and the pressure parameters collected by the smart bed can be recorded. That is to say, when the smart bed is in an invaded state, the control module can record this abnormal event and transmit relevant information (including occurrence time, pressure parameters, etc.) to the management and control terminal. The management and control terminal can be a smartphone application, a tablet application or a dedicated monitoring center. In this way, managers and wards can check and understand abnormal conditions on the bed at any time and respond in time.

[0127] It should be noted that the sleep-aiding light is warm light, the wake-up light is cool light, and the warning light is red light. The sleep-aiding light is set to warm light, such as warm yellow or warm white, which can create a warm and peaceful atmosphere, help relax the body and mind, and promote sleep. The wake-up light is set to cool light, such as cool white or light blue, which can produce a refreshing and bright effect, helping to awaken the user's consciousness and vitality. The alarm light is set to red light, which has a strong visual warning effect and can quickly attract attention.

[0128] like Figure 6 As shown, in some embodiments, the smart bed sleep monitoring method also has a turning over monitoring program, which identifies and determines the sleep state of the monitored person by monitoring the number of times the monitored person turns over. That is, the smart bed sleep monitoring method also includes the steps of:

[0129] S21, based on T sleep Pressure parameters within a time period to determine whether the person being monitored is in a sleeping state;

[0130] S22, if the guardian is in a sleeping state, calculate the 翻身 Turnover parameters corresponding to pressure parameters within a time period;

[0131] S23, determining whether the turning parameter is greater than a turning determination threshold;

[0132] S24, if the turning parameter is greater than the turning setting threshold, then record a turning;

[0133] If the turning parameter is less than or equal to the turning setting threshold, the execution step is based on T sleep The pressure parameters within the time period are used to determine whether the person being monitored is in a sleeping state.

[0134] Specifically, according to T before the current time period sleep Based on the pressure parameter, the pressure score X corresponding to the pressure parameter can be calculated. score , if the pressure score X score Both are greater than the sleep threshold X sleep , it means that the person being monitored is in a sleeping state. In other words, X Score >X sleep For [T now -T sleep ,T now ] are all established, where X Score is the pressure score, X sleep is the preset sleep threshold, T now is the current time, T sleep is the sleep time threshold.

[0135] When the ward is in a sleeping state, according to T 翻身 The pressure parameters within the time period are used to obtain the pressure vectors V1, V2,,,,V n ; Subtract the data in the pressure vector to obtain constants D1, D2,,,, D n-1 , where D n =V n -V n-1 ; For the above constant D n Perform length processing to obtain length values ​​d1, d2,,,,d n-1 ; Sum the length values ​​to obtain the turning parameter Then, it is determined whether the turning parameter S is greater than the turning determination threshold S th ; If S>S th , it means there is a turning action within the T time period, and the turning action is recorded.

[0136] Furthermore, after the step of recording a turn, the method further comprises the steps of:

[0137] S25, accumulating the time to obtain a first duration, until the first duration reaches the turning interval duration, then executing step based on T sleep The pressure parameters within the time period are used to determine whether the person being monitored is in a sleeping state.

[0138] Specifically, after recording a turning over action, the sleep state is determined again after a turning over interval, and the turning over monitoring program is executed, thereby avoiding repeated monitoring of a single turning over action, which helps to improve the accuracy of monitoring.

[0139] In some embodiments, the smart bed sleep monitoring method also has a bed monitoring program, so that the bed time of the ward can be monitored to prevent the ward from staying in bed for a long time. Especially in collective accommodation management such as schools, the bed monitoring program is more convenient for managers to manage.

[0140] That is to say, the smart bed sleep monitoring method also includes the steps of:

[0141] When the smart bed is occupied, accumulating the time to obtain a second duration;

[0142] Determine whether the second duration is greater than a duration threshold;

[0143] If the second duration is greater than the duration threshold, a reminder message is sent to the control terminal;

[0144] If the second duration is less than or equal to the duration threshold, the step of accumulating the time to obtain the second duration is executed when the smart bed is in an occupied state.

[0145] Specifically, if the pressure parameters on the smart bed remain unchanged during the second time period, it is considered that the person being cared for is sitting or lying in bed for a long time, and a reminder message will be sent to the control terminal (such as a smart phone, tablet computer or a dedicated monitoring center, etc.). This reminder message can include the accumulated time, recommended response measures, etc., so that the user or guardian can understand the situation in time and take appropriate measures, such as reminding the person being cared for to get up and move around.
