It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the term "comprising" and any variation thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0044] The embodiment of the present invention provides a vital sign information detection device, Figure 1 is a structural schematic diagram of a vital sign information detection device provided by an embodiment of the present invention, Figure 2 yes Figure 1 Schematic diagram of the partial structure of the toilet seat, reference Figure 1 and Figure 2 The vital sign information detection device is applied to a toilet, and the toilet includes a toilet seat 10. The vital sign information detection device includes: a detection module 20 and a processing module 30. The detection module 20 is electrically connected to the processing module 30, and at least a part of the detection module 20 is in contact with the toilet seat 10, and is used to generate a first detection electrical signal according to a vibration signal of the toilet seat 10, and output the first detection electrical signal to the processing module 30. The processing module 30 is used to filter the first detection electrical signal to obtain a second detection electrical signal corresponding to the vital sign information, and determine the vital sign information according to the second detection electrical signal; wherein the second detection electrical signal corresponds to a vibration signal with a vibration amplitude not greater than the micron level.

[0045] The toilet seat 10 is located on the toilet body, and the toilet seat 10 can have at least two states: raised and lowered. When the toilet seat 10 is in the lowered state, a person can sit on the toilet seat 10 and contact the toilet seat 10 to ensure comfort. When the toilet seat 10 is in the raised state, the angle between the toilet seat 10 and the upper surface of the toilet body is greater than 0 degrees. The shape of the toilet seat 10 is annular, and the annular toilet seat 10 encloses a seat opening, and the shape of the seat opening is adapted to the opening shape of the toilet body.

[0046] The vital sign information detection device includes a detection module 20 and a processing module 30, and at least a portion of the detection module 20 is in contact with the inner surface of the toilet seat 10, for example, the structure for vibration signal detection in the detection module 20 is in contact with the inner surface of the toilet seat 10. The inner surface of the toilet seat 10 is a surface that does not come into contact with the human body when the toilet seat 10 is in a falling state. In some optional embodiments of the present invention, the inner surface of the toilet seat 10 is a surface that is not exposed when the toilet seat 10 is in a lifted state and a fallen state. At least a portion of the detection module 20 is in contact with the inner surface of the toilet seat 10, and in an optional embodiment of the present invention, at least a portion of the detection module 20 is in contact with the inner surface of the toilet seat 10. In another optional embodiment of the present invention, an adhesive layer may be included between at least a portion of the detection module 20 and the inner surface of the toilet seat 10, and the two are adhered by the adhesive layer. By fitting the detection module 20 with the inner surface of the toilet seat 10, it is not necessary to make a hole in the toilet seat 10, which is convenient for installation and does not affect the appearance. In addition, the detection module 20 does not contact the human body when the human body sits down, which improves comfort and thus improves user experience.

[0047] The human body will vibrate when the heartbeat or breathing occurs. When the human body sits on the toilet seat 10, the human heartbeat or breathing will cause the toilet seat 10 to vibrate. Therefore, the vibration signal of the toilet seat can reflect the vibration of the human body. In this embodiment, the detection module 20 can collect the vibration signal of the toilet seat 10, and generate a first detection electrical signal according to the vibration signal of the toilet seat 10. Different vibration signals correspond to different first detection electrical signals. In the use scenario of the toilet, there may be many interfering vibration signals other than the vibration signals corresponding to the vital signs such as the heartbeat and / or breathing of the human body. The vibration amplitude of the interfering vibration signal is usually different from the vibration amplitude of the vibration signal corresponding to the vital sign. Accordingly, the voltage magnitude and / or frequency of the first detection electrical signal will be different. The processing module 30 can perform filtering processing based on the voltage amplitude of the first detection electrical signal to filter out the first detection electrical signal corresponding to the interference vibration signal, obtain the second detection electrical signal corresponding to the vital sign information, and determine the vital sign information based on the second detection electrical signal. The vital sign information includes but is not limited to heart rate and / or respiratory rate. In this way, the detection of human life characteristics information is achieved and the accuracy of vital sign information detection is improved. In some optional embodiments of the present invention, the vital sign information detection device may also include a display module, and the display module may display the vital sign information. In another optional embodiment of the present invention, the vital sign signal determined by the processing module 30 can be transmitted to the terminal used by the user, so that the user can learn about the vital sign information in a timely manner.

[0048] The vital sign information detection device of this embodiment, by fitting at least part of the detection module with the inner surface of the toilet seat, allows the detection module to detect the vibration signal of the toilet seat caused by the heartbeat or breathing when the human body sits down. The detection module can generate a first detection electrical signal according to the vibration signal of the toilet seat, and output the first detection electrical signal to the processing module. The processing module filters the first detection electrical signal to filter out the first detection electrical signal corresponding to the interference vibration signal, obtains the second detection electrical signal corresponding to the vital sign information, and determines the vital sign information according to the second detection electrical signal, thereby realizing the detection of the vital sign information. The technical solution of this embodiment, by fitting the detection module with the inner surface of the toilet seat, does not need to open a hole in the toilet seat, is easy to install and does not affect the appearance. In addition, the detection module will not contact the human body when the human body sits down, which improves comfort and thus improves user experience. Since the vibration amplitude of the toilet seat caused by vibration signals such as human pulse, heartbeat and breathing is relatively small, in this embodiment, the first detection electrical signal corresponding to the interfering vibration signal is filtered out by the processing module, and the second detection electrical signal corresponding to the vibration signal with a vibration amplitude not greater than the micron level is obtained. After the first detection electrical signal is filtered by the processing module, the second detection electrical signal obtained can correspond to the vibration signal corresponding to the human body's vital signs information such as human pulse, heartbeat and breathing, thereby eliminating the interference of large-amplitude vibration of the toilet seat caused by collision, etc., and can improve the accuracy of vital signs information monitoring.

[0049] Continue to refer Figure 1 Optionally, the detection module 20 includes an optical fiber sensing unit 21 and a photoelectric conversion unit 22 . Figure 3 is a schematic diagram of a detailed module structure of a vital sign information detection device provided by an embodiment of the present invention, with reference to Figure 2 and Figure 3 The optical fiber sensing unit 21 is connected to the photoelectric conversion unit 22, and at least a portion of the optical fiber sensing unit 21 is in contact with the inner surface of the toilet seat 10; the optical fiber sensing unit 21 is used to output a light detection signal to the photoelectric conversion unit 22 according to the pressure corresponding to the vibration signal, and the photoelectric conversion unit 22 is used to convert the light detection signal into a first detection electrical signal.

[0050] In this embodiment, the optical fiber sensing unit 21 includes an optical fiber sensing head 211, two couplers 212 and a laser 213. The optical fiber sensing head 211 is fitted with the inner surface of the toilet seat 10, so that the pressure on the toilet seat 10 can be transmitted to the optical fiber sensing head 211 in time. After the human body sits down, the pressure on the toilet seat 10 changes due to vibration signals such as breathing, heartbeat or body movement, and the toilet seat 10 will be deformed due to the pressure caused by the vibration signal. Correspondingly, the pressure on the optical fiber sensing head 211 changes due to vibration signals such as breathing, heartbeat or body movement, and the optical fiber sensing head 211 will be deformed due to the pressure caused by the vibration signal, so that the optical fiber sensing unit 21 can detect the vibration signal through the optical fiber sensing head 211. The photoelectric conversion unit 22 may include a photodetector 221. The optical fiber sensor head 211 can be disposed inside the toilet seat 10 , the coupler 212 and the laser 213 can be integrated with the photodetector 221 in the photoelectric conversion module 24 , and the photoelectric conversion module 24 can be disposed outside the toilet seat 10 .

[0051] The two couplers 212 are respectively a start coupler and a terminal coupler. The start coupler is connected to the start end of the optical fiber sensor head 211 through the optical fiber 23 , and the terminal coupler is connected to the terminal of the optical fiber sensor 211 through the optical fiber 23 . Figure 4 This is a schematic diagram of the pressure corresponding to the vibration signal collected by the optical fiber sensor head. Figure 3 and Figure 4 Specifically, based on the Mach-Zehnder interference principle: the laser 213 sends a light beam to the fiber optic sensor head 211 through the optical fiber 23, and the light beam is divided into two light beams after being transmitted to the starting coupler 212. The two light beams form interference and coupling through the output end face of the terminal coupler 212. When the fiber optic sensor head 211 receives the pressure change caused by the vibration, it will affect the phase difference of the two light beams, thereby causing the output light intensity to change. The photoelectric detector 221 of the photoelectric conversion unit 22 receives the changed light intensity signal and converts the light signal into a first detection electrical signal through the photoelectric effect. Then the processing module 30 analyzes and processes the first detection electrical signal. The processing module 30 can obtain corresponding vital signs information such as respiratory rate and / or heart rate according to the first detection electrical signal.

[0052] in, Figure 3 In the figure, the optical fiber sensor head 211 is a runway type as an example. The shape of the optical fiber sensor head 211 can also be circular, elliptical, square, rectangular or polygonal, and the area of ​​the optical fiber sensor head 211 can be adjusted according to actual needs. The embodiment of the present invention does not make any specific limitation here.

[0053] Combination Figure 3 and Figure 4, wherein the optical fiber sensor head 211 and the coupler 212 can be connected by an optical fiber line. The length of the optical fiber line 23 can be 0.3 meters to 10 meters. For example, the length of the optical fiber line 23 can be 0.5 meters, 1 meter or 3 meters. The number of lasers 213 can be 1, and the number of photodetectors 221 can be 3. The laser 213 adopts single-mode output, and the laser wavelength of the laser 213 is in the C band. The detection range of the photodetector 221 is 1100nm-1650nm.

[0054] Figure 5 This is a schematic diagram of the processing module. Figure 5 In some optional embodiments of the present invention, a program module 300 is embedded in the processing module 30, and the program module 300 includes a filtering program unit 31 and a determining program unit 32. When the filtering program unit 31 is executed, the first detection electrical signal is filtered to at least filter out the electrical signal corresponding to the vibration signal with a vibration amplitude greater than or equal to the first preset vibration amplitude, and / or the electrical signal corresponding to the vibration signal with a vibration amplitude less than the second preset vibration amplitude to obtain the second detection electrical signal; the determining program unit 32 is used to determine the vital sign information according to the second detection electrical signal when it is executed; wherein the first preset vibration amplitude is not less than millimeter-level vibration; and the second preset vibration amplitude is micron-level vibration.

[0055] Among them, the deformation caused by the vibration signals corresponding to heartbeat and breathing on the toilet seat 10 and the optical fiber sensing unit 21 is micron-level deformation. The deformation caused by the vibration signals of larger amplitude such as body movement or collision on the toilet seat 10 and the optical fiber sensing unit 21 is millimeter-level deformation. When the wind blows on the toilet seat, the deformation caused on the toilet seat 10 and the optical fiber sensing unit 21 is less than micron-level deformation. The processing module 20 may include a single-chip microcomputer, and the single-chip microcomputer may be embedded with programs corresponding to the filtering program unit and the determining program unit, respectively. When the filtering program unit 31 is executed by the single-chip microcomputer, the electric signal corresponding to the vibration signal greater than or equal to the preset vibration amplitude and / or the electric signal corresponding to the vibration signal less than the second preset vibration amplitude in the first detection electric signal is filtered out, so that larger millimeter-level vibration deformation (body movement, collision, etc.) signals and other unnecessary vibration signals, such as slight deformation of the toilet seat 10 and the optical fiber sensor unit 21 caused by wind, can be excluded. When the determination program unit 32 is executed by the single-chip microcomputer, the collected vibration signal of the micron-level deformation is analyzed and calculated, and the second detection electric signal corresponding to the regular high-frequency and low-frequency micron-level vibration signals of breathing or heartbeat is converted into the required vital signs information of heart rate and breathing rate, which can avoid the interference of body movement, collision or wind on the detection of vital signs information and ensure the accuracy of the detected vital signs information.

[0056] In some optional embodiments of the present invention, the voltage amplitude of the first detection electrical signal is positively correlated with the amplitude of the vibration signal. When the filtering program unit 31 is executed, filtering processing can be performed based on the voltage amplitude of the first detection electrical signal to filter out the first detection electrical signal with a larger voltage amplitude corresponding to body movement or collision, and the first detection electrical signal with a smaller voltage amplitude corresponding to deformation caused by wind, so as to obtain the second detection electrical signal corresponding to vital signs such as human heartbeat and / or breathing. In other optional embodiments, when the filtering program unit 31 is executed, filtering processing can also be performed based on the frequency of the first detection electrical signal to obtain the second detection electrical signal, which is not specifically limited in the embodiments of the present invention.

[0057] Optionally, the filtering program unit 31 is also used to extract a continuous electrical signal of a vibration signal whose frequency change meets a set frequency threshold in the first detection electrical signal as the second detection electrical signal when being executed; wherein the frequency of the set frequency threshold meets the vibration frequency of vital signs, and the vital signs include at least one of pulse vibration, breathing and heartbeat.

[0058] Specifically, the vibration frequency of the vibration signal corresponding to vital signs information such as pulse vibration, heartbeat, and breathing is usually relatively stable, so the vibration signal of the toilet seat vibration caused only by the vital signs information of the human body is also stable. The frequency of the vibration signal of the toilet seat vibration caused by collisions, etc. varies relatively greatly. In addition, the frequency of the vibration signal of the toilet seat vibration caused by the human body just sitting on the toilet seat and the frequency of the vibration signal of the toilet seat vibration caused by the human body leaving the toilet seat will also be relatively large. Therefore, within a period of time when the human body just sits on the toilet seat, the frequency of the vibration signal superimposed by the vibration signal of the toilet seat vibration caused by the human body sitting on the toilet seat and the vibration signal of the toilet seat vibration caused by the human body vital signs information will also vary greatly. After the human body sits on the toilet seat for a period of time, during the period when the human body sits stably on the toilet seat, the vibration frequency of the vibration signal of the toilet seat is basically consistent with the vibration frequency of the vibration signal of the human body vital signs. Accordingly, during the period when the human body sits stably on the toilet seat, the frequency change of the first detection electrical signal will conform to the vibration frequency of the vibration signal of the human body vital signs. In this embodiment, when the filtering program unit 31 is executed, a continuous electrical signal whose frequency change meets the set frequency threshold is extracted from the first detection electrical signal to obtain a second detection electrical signal, and then the electrical signal corresponding to the vibration signal in the frequency stability period can be obtained as the second detection signal, ensuring that the second detection signal corresponds to the vital sign information, and further ensuring the accuracy of the vital sign information determined by the determination program unit 32 based on the second detection signal.

[0059] In some optional embodiments of the present invention, the amplitude of the second detection electrical signal is correlated with the vital signs information, and when the determination program unit 32 is executed, the vital signs information can be determined based on the amplitude of the second detection electrical signal; in other optional embodiments, the frequency of the second detection electrical signal is correlated with the vital signs information, and when the determination program unit 32 is executed, the vital signs information can be determined based on the frequency of the second detection electrical signal.

[0060] Figure 6 This is another schematic diagram of the processing module, refer to Figure 6 In some optional embodiments of the present invention, the processing module also includes a seat rise and fall detection program unit 33, which is used to determine the sitting state of a human body according to a first detection electrical signal within a first preset time period after an electrical signal whose vibration amplitude is greater than or equal to a first preset vibration amplitude in the first detection electrical signal when being executed; the filtering program unit 31 is used to determine whether a human body sits on the toilet seat or leaves the toilet seat in the seat rise and fall detection program unit 33; if the seat rise and fall detection program unit 33 determines that a human body sits on the toilet seat, the seat rise and fall detection program unit 33 controls the filtering program unit 32 to execute, and the filtering program unit 32 is used to filter the first detection electrical signal when being executed; if the seat rise and fall detection program unit 33 determines that a human body leaves the toilet seat, the seat rise and fall detection program unit 33 controls the filtering program unit 32 not to execute.

[0061] Among them, the seat rise and fall detection program unit 33 can also be embedded in the processing module. Optionally, the seat rise and fall detection program unit 33 can determine that the human body is sitting down when the change of the first detection electrical signal in the first detection electrical signal corresponding to the first preset time length after the electrical signal with a vibration amplitude greater than or equal to the first preset vibration amplitude meets the preset rule. The preset rule corresponds to the change of the vital signs information of the human body. The seat rise and fall detection program unit determines that the human body stands up when the first detection electrical signal in the first detection electrical signal corresponding to the first preset time length after the electrical signal with a vibration amplitude greater than or equal to the first preset vibration amplitude corresponds to the same voltage amplitude or frequency. Optionally, after the human body sits on the toilet seat, the seat rise and fall detection program unit 33 outputs an enable message to the filter program unit 31, so that the filter program unit 31 executes and filters the first detection electrical signal. Optionally, after the human body leaves the toilet seat, the seat rise and fall detection program unit 33 does not output an enable message to the filter program unit 31, so that the filter program unit 31 does not execute. Optionally, under the condition that the filtering program unit 31 is not executed, the determining program unit 32 is also not executed. Specifically, after the filtering program unit 31 is executed, the filtering program unit 31 can output an enable message to the determining program unit 32, so that the program of the determining program unit 32 is executed. When the filtering program unit 31 is not executed, the filtering program unit 31 does not output an enable message to the determining program unit 32, so that the program of the determining program unit 32 is not executed. By setting the seat-up and seat-down detection program unit 33, it can be determined that the vital signs information of the human body is detected after the human body is seated. On the one hand, it is conducive to further improving the accuracy of the vital signs information detection, and on the other hand, it is conducive to saving the power consumption of the processing module.
