The invention generally relates to a bed, and more particular to a control system and a smart bed with the control system.
Sleep is critical for people in every aspect of their lives. Beds are necessary furniture for people to sleep on. An electric bed generally has smart/intelligent functions such as a posture adjustment function and a user sleep data collection function. A user can adjust the bed to raise the back or legs to a certain angle according to their needs, especially when the user is reading a book, watching TV or resting while sick, lying half-sitting on the bed. The posture is more comfortable, therefore, electric beds are widely used in hospitals and homes.
In addition, by utilizing certain sensors installed in an electric bed, the user sleep data can be collected for analysis of the sleep status of the user. Usually, the analysis of the sleep status of the user is performed through big data of a cloud server, which requires the collected user sleep data by the sensors be uploaded to the cloud server, and the cloud server performs corresponding data processing, and then sends it to a user terminal, which may require the subscription of the cloud server, thereby increasing the cost on one hand, and have the risk in a leakage of user privacy on the other hand.

As shown in
The control box 10 in one embodiment comprises a control panel 100 with an operating system coupled with the signal acquisition and processing module 20 and the controller 30 and configured to obtain user sleep data from the signal acquisition and processing module 20, generate operation instructions based on the obtained user sleep data, and send the operation instructions to the controller 30. In one embodiment, the operating system is, but is not limited to, a Linux operating system. One benefit of the control panel 100 with the operating system is that the obtained user sleep data can be processed locally through the control panel 100 with the Linux operating system, instead of uploading the user sleep data to an cloud service in which the user sleep data is processed, which could avoid the risk of data leakage for the user.
In some embodiments, the control panel 100 with the operating system comprises a system on a chip (SoC) having a microprocessor coupled with the sleep data analysis module 110 and the wireless communication module 120. For example, the control panel 100 may include a printed circuit board (PCB) with an application specific integrated circuit (ASIC), a field programmable gate array (FPGA); and/or a processor, along with memory and programmable input/output (I/O) peripherals.
The control box 10 also has a sleep data analysis module 110 configured to run in the control panel 100 with the operating system and generate sleep analysis data based on the user sleep data obtained from the signal acquisition and processing module 20 and a pre-trained sleep analysis model. In some embodiments, the sleep data analysis module 110 may be disposed/assembled in the PCB and electrically connected the input/output (I/O) peripherals of the control panel 100.
In some embodiments shown in
In some embodiments, after obtaining the user sleep data from the signal acquisition and processing module 20 through a data interface, the control panel 100 with the Linux operating system temporarily stores the collected/obtained user sleep data in an internal storage unit of the Linux operating system. When the temporary data (i.e., the temporary user sleep data) is accumulated and reaches the preset data amount, the accumulated user sleep data is input to the sleep analysis model unit 112. The preset data amount is, for example, but not limited to, defined based on the amount of sleep at one time.
Alternatively, when the accumulated time of the stored temporary data (i.e., the temporary user sleep data) reaches a preset time duration, the accumulated user sleep data is input to the sleep analysis model unit 112. Among them, the preset time duration is, for example, one day, one night, or 2 hours.
In some embodiments, the sleep analysis model unit 112 uses the accumulated user sleep data in the preset duration and/or the preset data amount as the input of the sleep analysis model to generate the sleep analysis data.
In some embodiments, the sleep analysis model is a pre-trained sleep analysis model based on a sleep staging algorithm. That is, in some embodiments, the sleep analysis model is pre-trained and can perform data analysis on the accumulated user sleep data to generate corresponding sleep analysis data. The sleep analysis model and the applied sleep staging algorithm are not limited to these disclosed herein. It should be appreciated that any sleep analysis model that can generate corresponding sleep analysis data based on the input of the user sleep data can be used as a preset sleep analysis model within the control panel 100 with the Linux operating system.
The control box 10 further has a wireless communication module 120 configured to run in the control panel 100 with the operating system and send the generated sleep analysis data to a user terminal 40 through a wireless network, so that the user terminal 40 can view all the sleep analysis data. In some embodiments, the wireless communication module 120 may be disposed/assembled in the PCB and electrically connected the input/output (I/O) peripherals of the control panel 100. In some embodiments, the sleep data analysis module 110 can preset the display mode, type, etc. of the sleep analysis data. The user can also configure the display mode, type, etc. of the sleep analysis data through the user terminal 40.
In some embodiments, the wireless communication module 120 includes, but is not limited to, a Bluetooth® communication module/protocol, a WiFi® communication module/protocol, a wireless network communication module/protocol, a near-field communication (NFC) communication module/protocol, and the like. In one embodiment, the wireless communication module 120 is preferably a Bluetooth communication module. That is, in operation, the control box 10 sends the sleep analysis data to the user terminal 40 via the Bluetooth® communication protocol, so that the user terminal 40 can view the sleep analysis data thereon. In other words, the user can directly acquire the sleep analysis data from the control box 10 through the user terminal 40 using Bluetooth® communication.
The user terminal 40 in some embodiments can be a smart mobile device, such as a smartphone, a tablet, a laptop, a computer, a remote control, or the like. Further, the control system may include an APP installed in the user terminal 40 with at least one graphic user interface (GUI) from which a user can configure and/or change certain configurations and/or operation parameters of the he control box 10, based on the user's preference and experience, for example, changing the preset duration and/or the preset data amount for which the user sleep data are accumulated, and/or the preset condition for determining if a user is snoring during sleep, if needed.
In one embodiment shown in
In some embodiments, the external memory module 130 is an external memory, which refers to the memory other than the operating system memory and the CPU cache in the control panel 100. Generally, the external memory can still save data after the power is turned off. In some embodiments, the external storage module 130 is, but not limited to, a hard disk, a floppy disk, an optical disk, a U disk, a flash drive, and the like.
In some embodiments, the sleep analysis data can be obtained through the external storage module 130 pluggable on the control panel 100 with the operating system. The user can plug the external storage module 130 on other card reading devices to read the obtained sleep analysis data therein.
Accordingly, the control box 10 can be used to monitor the user's sleep data so as to determine if the user is snoring, and adjust the position and angle of the back platform 101 of the bed through the controller 30 when the user snoring is determined, thereby to control or suppress the snoring of the user.
In addition, the user sleep data can also be used to analyze the sleep status of the user for providing health prediction, management and services, and preventing sudden situations such as myocardial infarction, cerebral infarction, and sudden death.

The smart bed includes a bed body 11 having a frame structure 12, at least one platform moveably attached to the frame structure 12, and a control system installed on the frame structure 12 and/or the at least one platform for controlling operations of the smart bed. The control system is disclosed above. The details of the control system is referred to the above descriptions and will not be repeated therein.
As shown in
The bed also includes a back lifting assembly 140 and a leg lifting assembly 150 moveably connected to the frame structure 12 and electrically coupled with the controller 30. The back lifting assembly 140 is configured to adjust the position and angle of the back platform 101, while the leg lifting assembly 150 is configured to adjust the positions and angles of the thigh platform 104 and the leg platform 105. Both the back lifting assembly 140 and the leg lifting assembly 150 can be operated individually or cooperatively, through the controller 30.
For the bed, when lying on the bed, a back portion and a leg portion of the user are corresponding to the back platform 101, and the thigh and leg platforms 104 and 105, respectively, and thus are in relation to the back lifting assembly 140 and the leg lifting assembly 140, respectively. Accordingly, the positions of the back portion and the leg portion of the user are individually and/or coordinately adjustable in accordance with operations of the back lifting assembly 140 and the leg lifting assembly 150. The back portion of the user may refer to the part or the whole of the upper body of the user, while the leg portion of the user may refer to the part or the whole of the lower body of the user.
As shown in
The leg lifting assembly 150 comprises a leg lifting bracket 151 pivotally coupled to the frame structure 12, and a leg lifting actuator 152 pivotally connected between the leg lifting bracket 151 and the frame structure 12 for operably driving the leg lifting bracket 151 to pivotally move in an upward rotating direction or a downward rotating direction relative to the frame structure 12, thereby causing the thigh and leg platforms 104 and 105 and therefore the leg portion of the use to be lifted up or lifted down.
During the sleep, the signal acquisition and processing module 20 acquires the user sleep data from the user, processes the acquired user sleep data, and transmits the processed user sleep data to the control box 10. The control box 10 receives the processed user sleep data from the signal acquisition and processing module 20, generates operation instructions based on the obtained user sleep data, and sends the operation instructions to the controller 30. Responsively the controller 30 performs the corresponding operations based on the operation instructions received from the control box 10.
In some embodiment, the operation instructions may include an anti-snoring instruction, when snoring data/event is detected from the user sleep data and meets a preset condition. When the controller 30 receives an anti-snoring instruction from the control box 10, it instructs the back lifting assembly 140 and/or the leg lifting assembly 150 to adjust the positions and angles of platforms, so as to suppress or reduce snoring of the user. For example, when receiving the anti-snoring instruction, the controller 30 instructs the back lifting assembly 140 to activate the back lifting actuator 142 to adjust the position and angle of the back platform 101. When the user feels the movement of the back platform 101, it may be wake up, or change sleep positions, thereby stopping or suppressing snoring. The angle of the back platform 101 at which the back lifting assembly 140 controls the back lifting actuator 142 to adjust is preferably but not limited to about 5-10°.
In addition, the operation instructions may also include adjust the positions and angles of the back platforms 101 and the thigh and leg platforms 104 and 105 at the user's preference. Furthermore, the user may be able to set up and/or change these positions and angles through the user terminal 40.
In addition, the bed also includes a driving mechanism 160 having a plurality of actuators 161, 162, 163 and 164 for driving the back assembly 140 and the leg assembly 150 and/or the massagers 171 and 172, respectively, based on the operation instruction from the controller 30. For example, in some embodiments, the actuators 161 and 162 are corresponding to the back lifting actuator 142 and the leg lifting actuator 152, respectively.
In some embodiments shown in
In some embodiments, the bed further includes a light bar 177 for displaying the working state of the bed. In addition, the bed may also include charging sockets 108 for providing charging functions.
In sum, according to the invention, the sleep data of the user can be analyzed within the bed through the control panel with the operating system, and the communication between the electric bed and the user terminal can be directly realized, which effectively avoid the uploading of the monitored sleep data of the bed to the cloud server, thereby reducing the risk in the data leakage of the user. The analysis of the user sleep data according to the invention requires no subscription of a cloud server and thus the cost can be reduced. In addition, the smart bed of the invention can collect various user sleep data such as the user respiration, the user heart rate, the user motion, snoring, etc., and monitor the user sleep data based on the preset sleep analysis model, which can achieve multi-dimensional and high-precision sleep analysis data. Further, by adjusting the position and angle of the back platform of the bed when snoring is detected, the user's snoring can be effectively suppress and controlled. Moreover, the sensors are installed on the upper surface of the platforms and directly contacts the user body during the sleep, which makes the collected user body sleep data more accurate.
