For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In addition, the technical features of the embodiments of the present application described below may be combined with each other as long as they do not collide with each other.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a sleep monitor according to an embodiment of the application. The sleep monitor comprises at least two signal detection processing units 10, a wake-up detection processing unit 20, a microprocessor unit 30 and a memory unit 40.
The signal detection processing unit 10 includes a sensor, a first power supply module, and an analog signal processing module. Wherein the analog signal processing module and the first power module are respectively connected with the microprocessor unit 30. In particular, the sensor may be a piezoelectric cable sensor or an optical fiber sensor, and is configured to sense pressure changes when a human body vibrates (such as breathing or heartbeat, etc.) to generate a first sensing signal. When the sensor is a piezoelectric cable sensor, the first sensing signal is a pressure signal; when the sensor is an optical fiber sensor, the first sensing signal is an optical fiber signal. The analog signal processing module is configured to amplify the first sensing signal, and transmit the amplified first sensing signal to the microprocessor unit 30. The first power module is used for supplying power to the signal detection processing unit 10 and is controlled by the switch of the microprocessor unit 30. In order to realize physiological signal detection for various lying positions during sleep of a human body, the sensors of the respective signal detection processing units 10 are provided at different positions based on the lying positions of the human body. It should be noted that, if the sensor is an optical fiber sensor, the sleep monitor may further include an optical fiber transmitting device and an optical fiber receiving device.
The wake-up detection processing unit 20 includes a second power module and a wake-up signal processing module. Wherein the second power module and the wake-up signal processing module are connected to the microprocessor unit 30, respectively, said wake-up signal processing module being further connected to a sensor of one of the signal detection processing units 10. Preferably, the wake-up signal processing module is connected to a sensor of one of the signal detection processing units 10 corresponding to the upper body position of the human body when the human body is lying normally. The sensor is used for detecting a wake-up signal when the sleep monitor is in a sleep state. Similarly, when the sensor is a piezoelectric cable sensor, the wake-up signal is a pressure signal; when the sensor is an optical fiber sensor, the wake-up signal is an optical fiber signal. The wake-up signal processing module is configured to amplify the wake-up signal collected by the sensor, and transmit the amplified wake-up signal to the microprocessor unit 30. The second power module is configured to supply power to the wake-up detection processing unit 20, and is in a normally open state.
The microprocessor unit 30 is configured to obtain a wake-up signal output by the wake-up detection processing unit 20 when the sleep monitor is in a sleep state, and determine whether the wake-up signal is a valid wake-up signal. Taking a piezoelectric cable sensor as an example, if the pressure value of the wake-up signal is greater than or equal to a preset wake-up signal pressure threshold value, judging the wake-up signal as an effective wake-up signal; in another embodiment, whether each wake-up signal collected in the continuous preset time period comprises a wake-up signal with a pressure value greater than or equal to a preset wake-up signal pressure threshold value is judged, if yes, whether the duration of each wake-up signal with the pressure value greater than or equal to the preset wake-up signal pressure threshold value is greater than or equal to a preset duration threshold value is further judged, and if yes, the wake-up signal is judged to be an effective wake-up signal.
When the microprocessor unit 30 judges that the wake-up signal is a valid wake-up signal, the sleep monitor is controlled to enter a working state, and the first power supply module of each signal detection processing unit is controlled to be started. Specifically, the microprocessor unit 30 performs on-off control on the first power supply module of each signal detection processing unit through its own GPIO.
When the microprocessor unit 30 determines that the wake-up signal is a non-valid wake-up signal, the first power module of each signal detection processing unit is kept in a turned-off state.
The microprocessor unit 30 is further configured to acquire first sensing signals acquired from different positions by each signal detection processing unit 10 when the sleep monitor is in an operating state; performing signal intensity analysis on each first sensing signal to obtain a first signal intensity value of each signal detection processing unit; judging whether a first signal intensity value of one signal detection processing unit 10 reaches a preset first signal intensity threshold value according to each first signal intensity value; if yes, controlling the first power module of one signal detection processing unit 10 reaching the first signal intensity threshold to be kept on, and closing the first power modules of other signal detection processing units; if not, the process proceeds to a step of acquiring the first sensing signals acquired from different positions by each signal detection processing unit 10.
In the prior art, the sleep monitor generally adopts an external power supply mode, and requires a corresponding power socket to be provided in a use environment, and requires a power line to be connected during use, so that the overall attractiveness of the product is affected. In the embodiment of the application, the sleep monitor can be powered by a battery, and in order to reduce standby power consumption, the power consumption of the second power supply module is lower than that of the first power supply module.
In some embodiments, the micro-processing unit 30 is further configured to implement a control method of the sleep monitor or a method for detecting a position of a human upper body according to any one of the embodiments of the present application described below when executing the computer program stored in the storage unit 40.
In some embodiments, the sleep monitor may be implanted in a home mattress, integrated with the home mattress. Specifically, the embodiment of the application also provides an intelligent mattress, which comprises a mattress body and the sleep monitor, wherein the sensors of the signal detection processing units of the sleep monitor are arranged at different positions in the mattress body based on the lying position of a human body.
In other embodiments, the sleep monitor further comprises a pad body, and the sensors of the respective signal detection processing units are disposed at different positions within the pad body based on the lying position of the human body. The sleep monitor may be placed on or under a home mattress as a stand alone pad.
The lying position of different people when sleeping is different. For the children, the phenomenon of overactivity is caused during sleeping, the lying position can appear at each position of the mattress, and at the moment, the sensors of each signal detection processing unit can be relatively and evenly distributed and arranged at a plurality of positions corresponding to the upper body parts of the children when lying in the cushion body of the intelligent mattress or the sleep monitor.
Fig. 5 is a schematic structural diagram of a sleep monitor for children according to an embodiment of the present application. The sleep monitor includes a pad body 51, three sensors 521, 522 and 523 of signal detection processing units disposed equidistantly along the length direction of the pad body 51, and a control box 53. When the child lies on the left side, the position of the sensor 521 corresponds to the upper body of the child, the acquired signal intensity value is the largest, and the physiological signal parameter value of the child is screened, monitored and analyzed; when the child lies on the right side, the sensor 523 is located at a position corresponding to the upper body of the child, and the acquired signal intensity value is the largest, so that the physiological signal parameter value of the child is screened, monitored and analyzed. Sensor 522 is located intermediate sensor 521 and sensor 523 and may be used to monitor and analyze physiological signal parameter values when the child is lying abnormally. It will be appreciated that the control box 53 includes three first power modules connected to the sensors 521, 522 and 523 of the three signal detection processing units, and further includes a wake-up detection processing unit, a microprocessor unit, a memory unit, and the like. The wake-up detection processing unit includes a second power module and a wake-up signal processing module, where the wake-up signal processing module is further connected to the sensor 522.
For adults, the sleeping posture is generally fixed, and the sensors of the signal detection processing units can be arranged in a plurality of positions corresponding to the upper body parts of the adult when the adult lies in the mattress body of the intelligent mattress or the sleeping monitor in a concentrated manner, and the positions are generally one or more positions close to the bed head. In the case of a double mattress, sensors may be provided on both sides of the double mattress near one or more locations at the head of the bed. Referring to fig. 2, fig. 2 is a flowchart of a control method of a sleep monitor according to an embodiment of the present application, where the method is applicable to the sleep monitor in fig. 1, the sleep monitor includes at least two signal detection processing units, each signal detection processing unit includes at least a sensor and a first power module, and the sensors of the signal detection processing units are disposed at different positions based on a lying position of a human body, and the method includes:
in step S201, first sensing signals acquired from different positions by each signal detection processing unit are acquired.
When the sleep monitor is in a working state, the sleep monitor acquires first sensing signals acquired from different positions by the signal detection processing units. Specifically, the sensor of each signal detection processing unit senses the pressure change when the human body vibrates to generate a first sensing signal. In general, each signal detection processing unit further includes an analog signal processing unit that amplifies and outputs the first sensing signal.
Step S202, signal intensity analysis is performed on each first sensing signal to obtain a first signal intensity value of each signal detection processing unit.
Specifically, the first sensing signals collected by each signal detection processing unit are analog signals, the microprocessor unit of the sleep monitor performs analog-to-digital conversion on the first sensing signals output by each signal detection processing unit according to a preset sampling frequency to obtain digitized signals of each signal detection processing unit, and performs signal intensity analysis on the digitized signals to obtain first signal intensity values of each signal detection processing unit.
In some embodiments, the microprocessor unit further performs a physiological parameter analysis on the digitized signal of the signal detection processing unit with the largest first signal intensity value, to obtain a first physiological signal parameter value, and outputs the first physiological signal parameter value.
In some cases, there may be a non-human object placed on the sleep monitor such that the sleep monitor wakes up to operate, in order to avoid this situation, the method further comprises: and judging whether the first physiological signal parameter value is 0, if so, controlling the first power supply module of each signal detection processing unit to be closed. It is understood that when the first physiological signal parameter value is 0, it indicates that the first sensing signal acquired by the signal detection processing unit is generated by pressure variation when the non-human body vibrates.
Optionally, the sleep monitor further includes a bluetooth module, and the bluetooth module establishes a communication connection with an external bluetooth receiving device, and transmits the first physiological signal parameter value to the external bluetooth receiving device.
Step S203, judging whether a first signal intensity value reaches a preset first signal intensity threshold according to each first signal intensity value, if so, proceeding to step S204, otherwise, proceeding to step S201.
Comparing the first signal intensity value of each signal detection processing unit with a preset first signal intensity threshold value, if the first signal intensity value of the signal detection processing unit is larger than or equal to the preset first signal intensity threshold value, the signal intensity of the signal detection processing unit is good, otherwise, the signal intensity of the signal detection processing unit is poor.
Specifically, a signal strength flag may be preset to identify whether the signal strength of each signal detection processing unit is good or not, and it is assumed that the sleep monitor includes three signal detection processing units in total, where the signal strength flag is defined as one byte (8 bits), the upper five bits default to 11111 (no meaning), and each of the lower three bits respectively represents whether the signal strength of one signal detection processing unit is good or not, where 0 represents that the signal strength is poor, and 1 represents that the signal strength is good. For example, if the signal strength flag is 11111111, it indicates that the signal strengths of all three signal detection processing units are good, and if the signal strength flag is 11111110, it indicates that the signal strength of the last signal detection processing unit is poor, and the signal strengths of the other two signal detection processing units are good. The microprocessor unit can judge whether one first signal intensity value exists in each first signal intensity value according to the signal intensity mark to reach a preset first signal intensity threshold value.
In step S204, the first power module of one of the signal detection processing units reaching the first signal intensity threshold is controlled to be turned on, and the first power modules of the other signal detection processing units are turned off.
Optionally, the power module of the signal detection processing unit that reaches the first signal intensity threshold and has the largest first signal intensity value is kept on, and the first power module of each other signal detection processing unit is turned off.
In some embodiments, the microprocessor unit 30 performs the switch control on the first power module of each signal detection processing unit through its GPIO.
In the embodiment of the application, the sleep monitor comprises a plurality of signal detection processing units, the sensors of the signal detection processing units are arranged at different positions based on the lying position of a human body, the signal intensity analysis is carried out on each first sensing signal by acquiring the first sensing signal collected from different positions of each signal detection processing unit, the signal detection processing units reaching a preset first signal intensity threshold value are screened out, the screened signal detection processing units are in an on state, and other signal detection processing units are controlled to be closed; so that the screened signal detection processing unit monitors and analyzes the pressure change of the human body during vibration to obtain various physiological signal parameter values of the human body.
