Among them, the seating detection method of the toilet seat provided by the embodiment of the present disclosure may be performed by the toilet seat. In some possible embodiments, referring to fig. 1, the toilet seat comprises a processor 12 disposed in the toilet seat housing, at least one electrode sheet 13 disposed on the upper surface of the toilet seat, and an optical module 14.

Wherein, the processor 12 is electrically connected with the at least one electrode sheet 13 and the optical module 14, respectively, and is configured to: detecting whether a contact object exists on the toilet seat according to the capacitance value corresponding to the at least one electrode slice 13; in response to determining that a contact is present on the toilet seat, detecting whether the contact is human skin using the optical module 14; determining that a person is seated on the toilet seat in response to determining that the contact is human skin.

Illustratively, the toilet seat housing includes a receiving space therein, which may be a closed space surrounded by upper and lower surfaces of the toilet seat, and the disposer 12 may be disposed in the receiving space during a manufacturing stage of the toilet seat.

For example, referring to fig. 2, the upper surface of the casing of the toilet seat 10 is provided with at least one notch 11, the at least one electrode tab 13 and the optical module 14 are disposed in the at least one notch 11, and the at least one electrode tab 13 and the optical module 14 are exposed to the outside and can be in contact with the skin of a human body when the human body is seated. For example, the at least one notch 11 is tangent to the edge of the toilet seat 10, so as to maximize the area of the at least one notch 11, which can ensure that the at least one electrode sheet 13 and/or the optical module 14 can sufficiently contact the skin of the human body in the case that the human body is seated, thereby being beneficial to improving the accuracy of the seating detection result.

It is understood that the shape of the notch 11 can be specifically set according to the actual application scenario. In an example, for example, the notch 11 is circular, oval, or rectangular, etc., the shape of the at least one electrode pad 13 and the optical module 14 may be adaptively determined according to the shape of the notch 11, and the shape of the at least one electrode pad 13 and the shape of the optical module 14 are also corresponding to circular, oval, or rectangular, etc. In another example, the notch 11 is a stepped hole, and the at least one electrode sheet 13 and the optical module 14 are shaped as a stepped protrusion that fits into the stepped hole.

In some embodiments, referring to fig. 3, the toilet seat 10 further comprises a capacitive detection sensor 15 disposed within the housing of the toilet seat 10; one end of the capacitance detection sensor 15 is connected to the electrode plate 13, and the other end is connected to the processor 12, and is configured to detect a capacitance value of the electrode plate 13 and transmit the capacitance value to the processor 12.

In some embodiments, the toilet seat 10 further comprises a communication module disposed within the toilet seat 10 housing; the communication module is connected with the processor 12 and is used for realizing the communication between the processor 12 and external equipment. The communication method used by the communication module in the embodiments of the present disclosure is not limited at all, and may be specifically set according to an actual application scenario, for example, the communication method used by the communication module includes but is not limited to: the internet, Local Area Network (LAN), Wide Area Network (WAN), bluetooth, Near Field Communication (NFC) technology, networks based on mobile data protocols such as General Packet Radio Service (GPRS), GSM, Enhanced Data GSM Environment (EDGE), 3G, 4G, or Long Term Evolution (LTE) protocols, Infrared (IR) communication technology, and/or WiFi, and may be wireless, wired, or a combination thereof.

In some embodiments, the toilet seat 10 further comprises a reservoir disposed within the toilet seat 10 housing; the memory is connected to the processor 12 for storing relevant data. Illustratively, the memory may include at least one type of storage medium including a flash memory, a hard disk, a multimedia card, a card type memory (e.g., SD or DX memory, etc.), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a Read Only Memory (ROM), an Electrically Erasable Programmable Read Only Memory (EEPROM), a Programmable Read Only Memory (PROM), or a magnetic memory, etc.

In some embodiments, the toilet seat 10 further comprises a power source disposed within the housing of the toilet seat 10 for powering the various components described above.

In some embodiments, during normal operation of a toilet with the toilet seat 10 installed thereon, the processor 12 in the toilet seat 10 controls the capacitance detection sensor 15 to perform polling, the capacitance detection sensor 15 continuously detects a capacitance value of the at least one electrode pad 13 and transmits the detected capacitance value to the processor 12, and the processor 12 determines whether a contact object exists on the electrode pad 13 according to the capacitance value. In the embodiment of the disclosure, in the normal working process of the toilet, only the capacitance value is needed to be used for contact detection, other data are not needed to be collected by other parts, the structure is simple, and the reduction of the power consumption of the toilet seat 10 is facilitated.

Further, in order to further reduce the power consumption of the toilet seat 10, the processor 12 in the toilet seat 10 may control the capacitance detection sensor 15 to poll for a set period of time, the capacitance detection sensor 15 continuously detects the capacitance value of the electrode pad 13 for the set period of time and transmits the detected capacitance value to the processor 12, and the processor 12 determines whether a contact exists on the electrode pad 13 according to the capacitance value. The set time period may be specifically set according to an actual application scenario, which is not limited in this disclosure.

In some possible embodiments, the processor 12 detects whether the capacitance value of the electrode pad 13 detected by the capacitance detection sensor 15 is within a first preset range after receiving the capacitance value, and if the capacitance value of the electrode pad 13 is within the first preset range, the processor 12 determines that a contact object exists on the electrode pad 13, and the capacitance value is valid data; if the capacitance value of the electrode slice 13 is not within the first preset range, the processor 12 determines that no contact exists on the electrode slice 13, and the capacitance value is invalid data, the processor 12 controls the capacitance detection sensor 15 to continue to detect the capacitance value of the electrode slice 13. It is understood that the first preset range may be specifically set according to the human body data, and the embodiment of the present disclosure does not set any limitation thereto.

When the at least one electrode sheet 13 is a plurality of electrode sheets 13, if the capacitance value of at least one electrode sheet 13 of the plurality of electrode sheets 13 is within a first preset range, it is determined that a contact object exists on the electrode sheet 13, otherwise, it is determined that the contact object does not exist on the electrode sheet 13.

In the case that it is determined that a contact object exists on the electrode sheet 13, the processor 12 controls the optical module 14 to emit an optical signal and receives an echo signal of the optical signal; for example, the optical module 14 includes at least one light emitting diode and at least one photodiode, and the optical module 14, under the control of the processor 12, uses the light emitting diode to emit a light signal, and receives an echo signal of the light signal through the photodiode and transmits the echo signal to the processor 12, for example, the echo signal is a signal of the light signal reflected back through the contact; the processor 12, after receiving the echo signal, may determine whether the contact object is human skin based on an intensity value of the echo signal. In the embodiment of the disclosure, the optical module 14 is controlled to operate only when it is determined that a contact object exists on the electrode sheet 13, so that the operating time of the optical module 14 can be reduced, and the power consumption of the toilet seat 10 can be effectively reduced.

The wavelength of the optical signal is not limited in this embodiment of the disclosure, for example, the optical signal is infrared light or visible light.

In some possible implementations, the processor 12 may detect whether the intensity value of the echo signal is within a second preset range, and if the intensity value of the echo signal is within the second preset range, the processor 12 determines that the contact object is human skin, and the echo signal is valid data; if the intensity value of the echo signal is not within a second preset range, the processor 12 determines that the contact object is not human skin, and the echo signal is invalid data, the processor 12 controls the capacitance detection sensor 15 to continue polling, the capacitance detection sensor 15 continuously detects the capacitance value of the electrode plate 13 and sends the detected capacitance value to the processor 12, and the processor 12 determines whether the contact object exists on the electrode plate 13 according to the capacitance value. It is understood that the second preset range may be specifically set according to the human body data, and the embodiment of the disclosure does not set any limitation thereto.

In some embodiments, to further improve the accuracy of the seating detection, the processor 12 may control the optical module 14 to emit multiple optical signals with the same wavelength but different intensities, and receive the echo signals corresponding to the multiple optical signals respectively. The processor 12 may determine whether the contact object is human skin based on the echo signals corresponding to the multiple optical signals, respectively. In the embodiment of the disclosure, the detection is performed by acquiring the multi-path echo signals based on the multi-path light pulses with the same wavelength but different intensities, which is beneficial to improving the accuracy of seating detection and avoiding or reducing the error problem of the single-path echo signals.

For example, the optical module 14 includes at least one light emitting diode and at least one photodiode, and the optical module 14, under the control of the processor 12, uses the at least one light emitting diode to emit multiple optical signals with the same wavelength but different intensities, where the multiple optical signals may be emitted by the at least one light emitting diode at preset time intervals, or the at least one light emitting diode is a plurality of light emitting diodes, and the multiple optical signals may be emitted by the plurality of light emitting diodes simultaneously, which is not limited in this disclosure. After the multiple optical signals with the same wavelength but different intensities are transmitted, the echo signals corresponding to the multiple optical signals are received by the at least one photodiode and transmitted to the processor 12, and then the processor 12 determines whether the contact object is human skin based on the intensity values of the multiple echo signals. In the embodiment of the disclosure, the detection is performed by acquiring the multi-path echo signals based on the multi-path optical signals with the same wavelength but different intensities, which is beneficial to improving the accuracy of seating detection and avoiding or reducing the error problem of the single-path echo signals.

Illustratively, because the intensities of the light signals emitted by the light emitting diodes are different, the second preset range corresponding to the echo signals of the light signals with different intensities is also different. After receiving the multiple echo signals, if the processor 12 detects that the intensity values of at least two echo signals are within a corresponding second preset range, it is determined that the contact object is human skin; if the multi-path echo signals are not in the corresponding second preset range, and it is determined that the contact object is not human skin, the processor 12 controls the capacitance detection sensor 15 to continue polling, the capacitance detection sensor 15 continuously detects the capacitance value of the electrode plate 13 and sends the detected capacitance value to the processor 12, and the processor 12 determines whether the contact object exists on the electrode plate 13 according to the capacitance value. In the embodiment of the disclosure, the contact object is determined to be the skin of the human body only when the at least two echo signals meet the requirements, which is beneficial to improving the accuracy of the sitting detection and avoiding or reducing the error problem of the single echo signal.

In one example, the processor 12 controls the at least one light emitting diode to emit 3 infrared light signals with intensity values of 30%, 60%, and 90% of light saturation current, respectively, and the corresponding second preset ranges are (M1, N1), (M2, N2), (M3, N3), which can be specifically set according to human body data, and then receive the 3 echo signals reflected by the contact object through the photodiode, and if the processor 12 determines that the intensity values of the 3 echo signals are within (M1, N1), (M2, N2), (M3, N3), respectively, it determines that the contact object is human skin; in the embodiment of the disclosure, the contact object is determined to be the skin of the human body only when the strength values of the multiple echo signals meet the requirements, so that the accuracy of sitting detection is improved, and the error problem of the single echo signal is avoided or reduced.

In some embodiments, the at least one electrode pad 13 is a plurality of electrode pads 13, and in the case that the plurality of electrode pads 13 are installed at both sides of the upper surface of the toilet seat, the plurality of electrode pads 13 may also be used to collect ECG signals of a human body. That is, after determining that there is a human body sitting on the toilet seat 10, the processor 12 may further acquire an ECG signal of the human body by using the plurality of electrode pads 13, so as to obtain electrocardiographic information, such as the electrocardiographic information including information about atrial fibrillation or sinus rhythm. In other words, for the toilet seat 10 to which the plurality of electrode pads 13 are mounted for health monitoring (for example, ECG signal measurement), the plurality of electrode pads 13 can be multiplexed for capacitance detection in seating detection, and a component for capacitance detection does not need to be additionally provided, so that hardware expenditure cost can be effectively reduced.

In some embodiments, where the optical module includes at least one light emitting diode and at least one photodiode, the optical module 14 may also be used to acquire PPG signals. That is, after it is determined that there is a human body sitting on the toilet seat 10, the processor 12 may further acquire the PPG signal of the human body by using the optical module 14, so as to obtain blood oxygen information and/or heart rate information, which may assist in determining the heart rate variability of the user. Thus, for the toilet seat 10 which is provided with the optical module 14 comprising at least one light-emitting diode and at least one photodiode and used for health detection, the optical module 14 can be multiplexed to carry out optical detection in sitting detection, and no part for optical detection is needed to be arranged additionally, so that the hardware expenditure cost can be effectively reduced.

In some embodiments, the at least one electrode pad 13 is a plurality of electrode pads 13, and in a case that the plurality of electrode pads 13 are installed on two sides of the upper surface of the toilet seat, and the optical module comprises at least one light emitting diode and at least one photodiode, after it is determined that a human body is seated on the toilet seat 10, the processor may further acquire an ECG signal of the human body using the plurality of electrode pads 13 and a PPG signal of the human body using the optical module 14. In other words, for the toilet seat 10 to which the plurality of electrode pads 13 and the optical module 14 are mounted for health detection, the plurality of electrode pads 13 and the optical module 14 can be multiplexed for seating detection without providing a separate member for seating detection and without modifying the structure of the existing member in the toilet seat 10, and thus hardware cost can be effectively reduced.

For collecting PPG signals, the optical module 14 comprises at least one light emitting diode and at least one photodiode, which emits green light through the tissue in the skin and arterial veins, reflected back into the photodiode when the optical module 14 is in contact with the human body. The absorption of light is substantially constant like muscles, bones, veins and other connective tissue, but the absorption of light naturally varies from blood to blood due to the flow of blood in arteries. The photodiode can convert the collected optical signal into an electrical signal (PPG signal) and send the electrical signal to the processor 12, and since the absorption of the artery to light changes and the absorption of other tissue light basically does not change, the obtained PPG signal can be divided into a direct current signal and an alternating current signal, and the alternating current signal in the PPG signal is extracted by the processor 12 to be processed and analyzed, so that the characteristics of blood flow can be analyzed.

Wherein, under the condition that the plurality of electrode pads 13 are used for collecting the ECG signal of the human body, the plurality of electrode pads 13 need to be respectively arranged on two sides of the upper surface of the toilet seat 10, so as to accurately collect the ECG signal.

In some embodiments, after determining that a human body is seated on the toilet seat 10, the processor 12 may detect a continuous contact time of the human body with the toilet seat 10 by using the at least one electrode pad 13, and measure biological information of the human body including, but not limited to, an ECG signal and/or a PPG signal, etc. by using the at least one electrode pad 13 and/or the optical module 14 when the continuous contact time reaches a preset time. In the embodiment of the present disclosure, in consideration of the problem of the sitting detection error, the biological information may be collected only when it is determined that the toilet seat 10 has a human body sitting thereon and has a certain continuous contact time, thereby being beneficial to ensuring the accuracy of the collected biological information.

Under the condition that the plurality of electrode plates 13 are respectively arranged on two sides of the upper surface of the toilet seat 10, the installation mode of the plurality of electrode plates 13 and the optical module 14 on the upper surface of the toilet seat 10 is not limited, and the electrode plates and the optical module can be specifically arranged according to actual application scenes.

In a possible implementation manner, the upper surface of the toilet seat 10 is provided with at least one notch 11, and a first electrode sheet 131 of the plurality of electrode sheets 13 and the optical module 14 may be disposed in the same notch 11, wherein an insulating medium is disposed between the optical module 14 and the first electrode sheet 131, and the insulating medium includes, but is not limited to, air, an insulating glue, or the like. In the embodiment of the present disclosure, the first electrode sheet 131 and the optical module 14 are integrated together and disposed in one notch 11, which is beneficial to reducing the number of notches 11 that need to be disposed on the toilet seat 10, saving the manufacturing cost, improving the manufacturing efficiency, and being beneficial to improving the aesthetic degree.

In an example, referring to fig. 4a and 4b, the first electrode sheet 131 is disposed around the optical module 14, for example, the first electrode sheet 131 is a circular ring electrode, and the optical module 14 is disposed in the circular ring electrode, so that the first electrode sheet 131 and the optical module 14 are integrated; fig. 4a and 4b show that the optical module 14 comprises two light emitting diodes and a photodiode arranged between the two light emitting diodes. In the embodiment of the present disclosure, the first electrode sheet 131 and the optical module 14 are integrated into a whole, and can be disposed in one notch 11, which is beneficial to reducing the number of notches 11 that need to be disposed on the toilet seat 10, saving the manufacturing cost, improving the manufacturing efficiency, and also beneficial to improving the aesthetic degree.

In another example, referring to fig. 5, the first electrode sheet 131 and the optical module 14 may be disposed on the same circuit board, the first electrode sheet 131 and the optical module 14 may be disposed on two sides of the circuit board, respectively, and an insulating medium is disposed between the optical module 14 and the first electrode sheet 131, so that high integration of the first electrode sheet 131 and the optical module 14 is achieved. In the embodiment of the present disclosure, the first electrode sheet 131 and the optical module 14 are integrated into a whole, and can be disposed in one notch 11, which is beneficial to reducing the number of notches 11 that need to be disposed on the toilet seat 10, saving the manufacturing cost, improving the manufacturing efficiency, and also beneficial to improving the aesthetic degree.

The notches 11 of at least two second electrode sheets 132 of the plurality of electrode sheets 13 and the notches 11 of the first electrode sheets 131 are positioned on two sides of the upper surface of the shell of the toilet seat 10. In some embodiments, the at least two second electrode sheets 132 may be respectively disposed in different notches 11.

In some possible embodiments, after receiving the dermatoglyph detection signal, the processor 12 processes the dermatoglyph detection signal to obtain dermatoglyph information, then compares the dermatoglyph information with pre-stored reference dermatoglyph information to determine a similarity between the two, and if the similarity satisfies a preset threshold, it determines that the comparison is successful, the processor 12 determines identity information of a user corresponding to a human body seated on the toilet seat 10 according to the identity information corresponding to the reference dermatoglyph, and further, the processor 12 may send a health information prompt to a user terminal of the user through a communication module based on the identity information and measured biological information (such as a PPG signal, an ECG signal, and the like) of the user; if the similarity does not meet the preset threshold, it is determined that the comparison fails, and the user corresponding to the human body seated on the toilet seat 10 is considered as a new user, and the processor 12 stores the dermatoglyph information in the memory. According to the embodiment of the disclosure, identity authentication is performed through the dermatoglyph detection signal, and then the measured biological information is associated and bound with the identity information, so that a user can conveniently watch self health monitoring data, and meanwhile, the user can only be allowed to check the self data based on the identity information, thereby effectively protecting the privacy of other users.

Furthermore, the biological information of different users can be classified and counted according to the identity information, for example, the comparison result of the biological information of each user is periodically sent to the user terminal of the corresponding user, so that the user can know the health condition of the user in a period of time.
