Health detection is a method of long-time monitoring of various vital signs (such as heart rate, respiration, blood pressure, etc.) of the human body. Health detection can not only reflect the health status of a person, but also give early warning of possible disease risks and give suggestions for improving the health status.

Based on the device, the vital sign detection method is to control the optical switch to switch to the first optical fiber sensor in time period 1 and to switch to the second optical fiber sensor in time period 2 by the synchronous control circuit, the optical signals collected by the first optical fiber sensor and the second optical fiber sensor are separated into the electrical signals corresponding to the optical signals collected by the first optical fiber sensor and the electrical signals corresponding to the optical signals collected by the second optical fiber sensor after photoelectric conversion, and the electrical signals corresponding to the first optical fiber sensor are spliced, and the electrical signals corresponding to the second optical fiber sensor are spliced, then the spliced electrical signals are sent to the processing module for processing, so as to obtain the vital signs of the human body of the first user detected by the first optical fiber sensor and the vital signs of the human body of the second user detected by the second optical fiber sensor. However, the optical switch needs to be controlled synchronously, which is costly. SUMMARY

[0004] The present application provides a vital sign detection method, device and equipment to solve the problems in related technologies, and the technical solutions are as follows:

[0005] In a first aspect, a vital sign detection method is provided. The method comprises: collecting a first optical signal, the first optical signal being a combined signal of a first sub-optical signal for detecting a first user's health condition and a second sub-optical signal for detecting a second user's health condition; dividing the first electrical signal into a first sub-electrical signal and a second sub-electrical signal according to a division point, the first sub-electrical signal corresponding to the first sub-optical signal, the second sub-electrical signal corresponding to the second sub-optical signal, the division point being a signal mutation point of the first electrical signal corresponding to the first optical signal; determining the vital sign of the first user according to the first sub-electrical signal and determining the vital sign of the second user according to the second sub-electrical signal. In the present application, by taking the signal mutation point of the first electrical signal as the division point of the first electrical signal, the electrical signal corresponding to the optical signal collected by each optical fiber sensor can be accurately separated, thereby detecting the vital signs of multiple users, and further realizing the detection of the health conditions of multiple users. The structure is simple, the cost is low, and the implementation is easy.

[0006] In a possible implementation, the method is applied to a vital sign detection device, and the device comprises a first optical fiber sensor and a second optical fiber sensor. The first optical signal is collected by: collecting the first sub-optical signal by the first optical fiber sensor; and collecting the second sub-optical signal by the second optical fiber sensor. In the present application, by collecting different optical signals by different optical fiber sensors, the health detection of multiple people can be realized.

[0007] In a possible implementation, the device further comprises a switching switch, which is used to switch between the first optical fiber sensor and the second optical fiber sensor. The first sub-optical signal is collected by the first optical fiber sensor in a first switching state of the switching switch. The second sub-optical signal is collected by the second optical fiber sensor in a second switching state of the switching switch, the second switching state being different from the first switching state. In the present application, since the switching switch in the vital sign detection device will generate a disturbance signal in the switching process, the disturbance signal can cause the electrical signal to mutate, that is, the signal mutation point of the first electrical signal can determine the division point of the first electrical signal. The electrical signal corresponding to the optical signal collected by each optical fiber sensor can be accurately separated, thereby detecting the vital signs of multiple users, and further realizing the detection of the health conditions of multiple users. The structure is simple, the cost is low, and the implementation is easy.

[0008] In a possible implementation, before the first optical signal is collected, the method further includes: adjusting a switching frequency of the switching switch, so as to control the switching switch to switch between the first optical fiber sensor and the second optical fiber sensor according to the adjusted switching frequency. In this application, by adjusting the switching frequency of the switching switch, multiple detection modes can be realized, and the detection mode can be selected according to the requirement, which is high in flexibility and practicability.

[0009] In a possible implementation, the first optical signal is collected by: when the switching frequency is a first frequency, collecting, in a first time period, the first sub-optical signal by the first optical fiber sensor; and collecting, in a second time period, the second sub-optical signal by the second optical fiber sensor, the second time period being adjacent to the first time period. In this application, by setting the switching frequency of the switching switch, the first optical fiber sensor and the second optical fiber sensor can alternately collect signals, so as to realize the purpose of multi-user rotation detection, which is high in practicability.

[0010] In a possible implementation, the first optical signal is collected by: when the switching frequency is a second frequency, collecting the first sub-optical signal by the first optical fiber sensor, and collecting the second sub-optical signal by the second optical fiber sensor. In this application, by setting the switching frequency of the switching switch, the first optical fiber sensor and the second optical fiber sensor can collect signals in parallel, so as to realize the purpose of multi-user simultaneous detection, which is high in practicability.

[0011] In a possible implementation, before the first electrical signal is divided into the first sub-electrical signal and the second sub-electrical signal according to the division point, the method further includes: determining signal mutation points of the first electrical signal corresponding to the first optical signal as the division points for dividing the first electrical signal. In this application, by determining the signal mutation points in the first electrical signal and determining these signal mutation points as the division points of the first electrical signal, the division point determination manner is simple, and all division points can be quickly found.

[0012] In a possible implementation, before the first electrical signal is split into the first sub-electrical signal and the second sub-electrical signal according to the split point, the method further includes: determining a first signal mutation point of the first electrical signal corresponding to the first optical signal; determining other signal mutation points of the first electrical signal except the first signal mutation point according to the first signal mutation point and a switching period of the switching switch; and determining that the first signal mutation point and the other signal mutation points are all split points for splitting the first electrical signal. In this application, by determining the first signal mutation point and combining the first signal mutation point and the switching period of the switching switch, the other signal mutation points in the first electrical signal are determined, all signal mutation points are found, and the signal mutation points are determined as the split points of the first electrical signal, so that the split point determination method is simple and all split points can be quickly found.

[0013] In a possible implementation, the signal mutation point of the first electrical signal is a time point corresponding to an instantaneous frequency, and the instantaneous frequency is a frequency greater than a first threshold in the first electrical signal. In this application, if the instantaneous frequency in the first electrical signal is greater than the first threshold, the time point corresponding to the instantaneous frequency is determined as the signal mutation point of the first electrical signal, and then the split point is determined. The split point is determined by the instantaneous frequency, which can more accurately determine the split point and improve the accuracy of the split point.

[0039] The terms used in the embodiment part of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0040] A vital sign detection device is used to detect various vital signs of a human body, such as heart rate, respiration, blood pressure, etc. The vital signs detected by the device can reflect the health status of a person, so as to improve the health level of the person. In a related technology, Figure 1 A structural schematic diagram of a vital sign detection device is provided in a related technology. As shown in Figure 1 The vital sign detection device 10 can include a first optical fiber sensor 11, a coherent detection module 12, an analog-to-digital conversion module 13, and a digital signal processing module 14. The first optical fiber sensor 11 is electrically connected to the coherent detection module 12, the coherent detection module 12 is electrically connected to the analog-to-digital conversion module 13, and the analog-to-digital conversion module 13 is electrically connected to the digital signal processing module 14. The first optical fiber sensor 11 can be arranged in a cushion. When a user sits on the cushion, the first optical fiber sensor 11 reflects the vibration signal of the user's body through the phase change of the optical signal, that is, the first optical fiber sensor 11 collects the phase-changed optical signal. The first optical fiber sensor 11 sends the optical signal to the coherent detection module 12. The coherent detection module 12 converts the optical signal into an electrical signal and sends the electrical signal to the analog-to-digital conversion module 13. The analog-to-digital conversion module 13 converts the electrical signal into a digital signal and sends the digital signal to the digital signal processing module 14. The digital signal processing module 14 obtains the vital signs of the user according to the digital signal, which can include heart rate, respiration, and blood pressure, etc., thereby realizing detection of the health status of the human body.

[0041] However, in some scenarios, in order to realize detection of the health status of multiple users, at least two optical fiber sensors are required. Figure 2 A structural schematic diagram of another vital sign detection device is provided. As shown in Figure 2 The vital sign detection device 20 is compared with Figure 1The difference between the illustrated vital sign detection device 10 and the device 20 is that it further includes a second optical fiber sensor 21, an optical switch 22, and a synchronization control circuit 23. The first optical fiber sensor 11 and the second optical fiber sensor 21 are both electrically connected to the optical switch 22, which is electrically connected to the coherent detection module 12, which is electrically connected to the analog-to-digital conversion module 13. The analog-to-digital conversion module 13 is electrically connected to the digital signal processing module 14 and the synchronization control circuit 23, respectively. The synchronization control circuit 23 is electrically connected to the optical switch 22. The optical switch 22 can periodically switch between the first optical fiber sensor 11 and the second optical fiber sensor 21. In this way, the synchronous control circuit 23 controls the optical switch 22 to switch to the first optical fiber sensor 11 during time period 1, and controls the optical switch 22 to switch to the second optical fiber sensor 21 during time period 2. After the optical signal collected by the first optical fiber sensor 11 and the optical signal collected by the second optical fiber sensor 21 undergo photoelectric conversion, the analog-to-digital conversion module 13 separates the electrical signal corresponding to the optical signal collected by the first optical fiber sensor 11 and the electrical signal corresponding to the optical signal collected by the second optical fiber sensor 12 according to time. The electrical signal corresponding to the first optical fiber sensor 11 and the electrical signal corresponding to the second optical fiber sensor 21 are spliced ​​and then sent to the digital signal processing module 14 for processing, thereby obtaining the vital signs of the first user detected by the first optical fiber sensor 11 and the vital signs of the second user detected by the second optical fiber sensor 21, thereby detecting the health status of the first user. However, the vital sign detection device 20 requires the synchronous control circuit 23 to synchronously control the optical switch 22 and the analog-to-digital conversion module 13 to ensure that the analog-to-digital conversion module 13 can separate the signal corresponding to the first optical fiber sensor 11 and the signal corresponding to the second optical fiber sensor 21, which requires additional hardware and is relatively costly.

[0042] In order to solve the above technical problems, the present invention provides a vital sign detection device. Figure 3 As shown, the vital signs detection device 30 is compared with Figure 2 The difference between the vital sign detection device 20 shown is that the vital sign detection device 30 does not include the synchronization control circuit 23. In this way, the embodiment of the present application realizes the separation of the electrical signals corresponding to the optical signals collected by different optical fiber sensors through the signal separation algorithm, without the need for additional hardware for synchronization control, and the cost is low. Figure 3The life sign detection device 30 shown in the embodiment of the present application provides a life sign detection method, which can include collecting a first light signal, the first light signal being a combined signal of a first sub-light signal for detecting a first user's health condition and a second sub-light signal for detecting a second user's health condition; determining a signal mutation point of a first electric signal corresponding to the first light signal as a segmentation point for segmenting the first electric signal; segmenting the first electric signal into a first sub-electric signal corresponding to the first sub-light signal and a second sub-electric signal corresponding to the second sub-light signal according to the segmentation point; determining a life sign of the first user according to the first sub-electric signal to detect the first user's health condition; and determining a life sign of the second user according to the second sub-electric signal to detect the second user's health condition. As can be seen, in the present application, the switch in the life sign detection device will generate a disturbance signal in the switching process, which can cause the electric signal to mutate, that is, the signal mutation point of the first electric signal can determine the segmentation point of the first electric signal, and the electric signal corresponding to the light signal collected by each optical fiber sensor can be accurately separated, so as to detect the life signs of multiple users, and then detect the health conditions of multiple users, which has a simple structure, low cost and is easy to implement.

[0043] Figure 3 The life sign detection device and the life sign detection method thereof can be applied to the following scenarios: scenario one, a hospital. Figure 3 The life sign detection device as a detection instrument detects the life signs of patients on multiple beds in the hospital, and then detects the health conditions of multiple patients. Scenario two, a vehicle. Figure 3 The first optical fiber sensor and the second optical fiber sensor in the life sign detection device are arranged on the seat cushions (such as the driver's seat cushion, the front passenger's seat cushion and the rear seat cushions) in the vehicle, and other devices (such as the switch, the processing module, etc.) of the life sign detection device are arranged on the vehicle controller. In this way, the life sign detection device can detect the life signs of multiple users sitting in the vehicle, and then detect the health conditions of multiple users. Scenario three, bedding. Figure 3 The life sign detection device is arranged on the mattress (such as a double mattress). In the case that two people lie on the bed, the life signs of the two people can be detected at the same time, and then the health conditions of multiple people can be detected. Of course, the life sign detection device and the life sign detection method thereof provided in the embodiment of the present application are not limited to the above scenarios, and can also include other scenarios, such as a sofa. The life sign detection device can be arranged on a multi-person sofa. In the case that multiple people sit on the sofa, the life signs of these people can be detected at the same time, and then the health conditions of these people can be detected. Therefore, in the embodiment of the present application, they are not listed one by one.

[0044] A life sign detection method provided in the embodiment of the present application is described in detail below.Figure 4 A flowchart of a vital sign detection method provided by an embodiment of the present application is shown in Figure 4 The method is applied to Figure 3 The method can include S401-S404 (some steps are optional).

[0045] S401, collect a first optical signal, the first optical signal being a combined signal of a first sub-optical signal for detecting a first user's health condition and a second sub-optical signal for detecting a second user's health condition.

[0046] Exemplarily, the first sub-optical signal can be understood as a section of the first optical signal, the second sub-optical signal can be understood as another section of the first optical signal, and the first optical signal can be understood as a combined signal of the first sub-optical signal and the second sub-optical signal.

[0047] In an example, the execution subject of S401 can be at least two optical fiber sensors in the vital sign detection device. Exemplarily, the at least two optical fiber sensors include a first optical fiber sensor and a second optical fiber sensor. The first optical fiber sensor collects the first sub-optical signal, and the second optical fiber sensor collects the second sub-optical signal. In the embodiment of the present application, different optical signals can be collected by different optical fiber sensors to achieve health detection for multiple people.

[0048] In another example, the vital sign detection device can further include a switching switch, which is used to switch between the first optical fiber sensor and the second optical fiber sensor. The first optical fiber sensor collects the first sub-optical signal when the switching switch is in a first switching state; the second optical fiber sensor collects the second sub-optical signal when the switching switch is in a second switching state, which is different from the first switching state. In the embodiment of the present application, since the switching switch in the vital sign detection device will generate a disturbance signal in the switching process, the disturbance signal can cause the electrical signal to mutate, i.e., the signal mutation point of the first electrical signal can determine the division point of the first electrical signal, and the electrical signal corresponding to the optical signal collected by each optical fiber sensor can be accurately separated, so as to detect the vital signs of multiple users, and further to achieve health condition detection for multiple users, which is simple in structure, low in cost, and easy to implement.

[0049] In some embodiments, in order to make the detection mode diverse, the health detection mode can be switched by adjusting the switching frequency of the switching switch. Therefore, as shown in Figure 5 Before S401, the vital sign detection method provided by the embodiment of the present application can further include:

[0050] S400, adjust the switching frequency of the switching switch.

[0051] The switching frequency can be determined according to actual conditions and is not specifically limited in the embodiments of the present application.

[0052] S401 can be implemented as follows: collecting the first optical signal according to the correlation between the switching frequency and the health detection mode. The correlation between the switching frequency and the health detection mode is pre-stored and is not specifically limited here.

[0053] For example, when the switching frequency is the first frequency, the corresponding detection mode is the single-channel detection mode; when the switching frequency is the second frequency, the corresponding detection mode is the round-robin detection mode; and when the switching frequency is the third frequency, the corresponding detection mode is the parallel detection mode. The third frequency is greater than the second frequency, and the second frequency is greater than the first frequency.

[0054] In Example 1, the switching frequency is a first frequency, such as 0 Hz. The health detection mode is a single-channel detection mode. That is, when the switching frequency is 0 Hz, the first optical fiber sensor collects the first sub-light signal, or the second optical fiber sensor collects the second sub-light signal.

[0055] In Example 2, the switching frequency is the second frequency, for example, less than 0.2 / number of fiber sensors Hz. In this case, the health detection mode is the rotation detection mode. That is, when the switching frequency is less than 0.1 Hz, during the first period, the first optical sub-signal is collected by the first fiber sensor; during the second period, the second optical sub-signal is collected by the second fiber sensor, with the second period being adjacent to the first period.

[0056] In Example 3, if the switching frequency is the third frequency and is greater than 15 times the number of optical fiber sensors (Hz), the health detection mode is the parallel detection mode. That is, when the switching frequency is greater than 30 Hz, the first optical fiber sensor collects the first sub-light signal, and the second optical fiber sensor collects the second sub-light signal.

[0057] In the embodiments of the present application, by adjusting the switching frequency of the toggle switch, multiple detection modes can be implemented, and the detection mode can be selected according to needs, which has high flexibility and high practicality. For example, by setting the switching frequency of the toggle switch, the first fiber optic sensor and the second fiber optic sensor can be alternately collected signals, achieving the purpose of multi-user rotation detection, which is highly practical. For another example, by setting the switching frequency of the toggle switch, the first fiber optic sensor and the second fiber optic sensor can be parallel collected signals, achieving the purpose of multi-user simultaneous detection, which is highly practical.

[0058] S402: Determine a signal mutation point of a first electrical signal corresponding to the first optical signal as a segmentation point for segmenting the first electrical signal.

[0059] The signal mutation point can be understood as a point where the signal suddenly changes. For example, the signal mutation point can be the moment corresponding to a sudden change in voltage, current, or frequency of the electrical signal.

[0060] In one possible implementation, S402 may be implemented as follows: when the instantaneous frequency of the first electrical signal is greater than a first threshold, determining the moment corresponding to the instantaneous frequency as the segmentation point of the first electrical signal. Of course, it is not limited to this, and may also be: when the instantaneous voltage of the first electrical signal is greater than a second threshold, determining the moment corresponding to the voltage as the segmentation point of the first electrical signal. Alternatively, when the instantaneous current of the first electrical signal is greater than a third threshold, determining the moment corresponding to the current as the segmentation point of the first electrical signal. The first threshold, the second threshold, and the third threshold may be set according to actual conditions. In an embodiment of the present application, by determining the signal mutation points in the first electrical signal and determining these signal mutation points as the segmentation points of the first electrical signal, the segmentation point determination method is simple and all segmentation points can be quickly found.

[0061] In another possible implementation, S402 may be implemented as follows: S4021. Determine a first signal mutation point in the first electrical signal corresponding to the first optical signal. Exemplarily, the signal mutation point in the first electrical signal is a moment corresponding to an instantaneous frequency, where the instantaneous frequency is a frequency in the first electrical signal that is greater than a first threshold. S4022. Determine other signal mutation points in the first electrical signal other than the first signal mutation point based on the first signal mutation point and the switching cycle of the switch. It can be understood that since signal mutation points occur during the switching process of the switch, only one signal mutation point in the first electrical signal needs to be determined. Based on this signal mutation point and the switching cycle of the switch, all signal mutation points in the first electrical signal can be determined. Exemplarily, assuming that the first signal mutation point in the first electrical signal is moment 1 and the switching cycle is 1 minute, then it can be determined that moment 2, which is time 1 + 1 minute in the first electrical signal, corresponds to the second signal mutation point. Similarly, moment 2 + 1 minute in the first electrical signal corresponds to the third signal mutation point. S4023. Determine that the first signal mutation point and other signal mutation points are all segmentation points for segmenting the first electrical signal. In the embodiment of the present application, it is only necessary to determine a signal mutation point in the first electrical signal, and then all signal mutation points in the first electrical signal can be obtained based on the signal mutation point and the switching cycle of the switching switch, so that the method for determining the segmentation point is simple and easy to implement.

[0062] However, the above manner can have an accuracy problem of determining the division points, and therefore, in another possible implementation manner, S402 can be implemented as: after the threshold period of the switching switch, S4024, determining a second signal mutation point of the first electrical signal corresponding to the first optical signal. It can be understood that: after the threshold period, the signal mutation points of the electrical signal are determined again according to the instantaneous frequency and the like in the electrical signal. Then, S4022, determining other signal mutation points of the first electrical signal except the second signal mutation point according to the second signal mutation point and the switching period of the switching switch. S4023, determining that the second signal mutation point and the other signal mutation points are all division points for dividing the first electrical signal. In the embodiment of the present application, the signal mutation points in the electrical signal are determined again after the threshold period of the switching switch, and all the signal mutation points in the first electrical signal can be obtained according to the signal mutation points and the switching period of the switching switch, and the signal mutation points are determined as the division points, so as to achieve the purpose of correction, and make the determination of the division points more accurate.

[0063] S403, dividing the first electrical signal into a first sub-electrical signal and a second sub-electrical signal according to the division points, the first sub-electrical signal corresponding to the first sub-optical signal, and the second sub-electrical signal corresponding to the second sub-optical signal.

[0064] After the division points are obtained in S402, the first electrical signal is divided into a first sub-electrical signal and a second sub-electrical signal according to the division points. Exemplarily, the first electrical signal includes an instantaneous frequency 1 and an instantaneous frequency 2, both of which are frequencies greater than a first threshold, then the processing module can determine a time 1 corresponding to the instantaneous frequency 1 and a time 2 corresponding to the instantaneous frequency 2. The processing module divides the first electrical signal with the time 1 and the time 2 as the division points. Then, the electrical signal corresponding to the starting time-time 1 is divided into the first sub-electrical signal, the electrical signal corresponding to the time 1-time 2 is divided into the second sub-electrical signal, and the electrical signal corresponding to the time 2-ending time is divided into the first sub-electrical signal.

[0065] S404, determining the vital signs of the first user according to the first sub-electrical signal and determining the vital signs of the second user according to the second sub-electrical signal, so as to detect the health conditions of the first user and the second user.

[0066] Exemplarily, the processing module can determine the vital signs of the first user according to the frequency in the first sub-electrical signal. For example, the frequency in the first electrical signal is determined to be 0.15-0.42 Hz, which is determined to be the respiratory signal of the first user. For another example, the frequency in the first sub-electrical signal is determined to be 0.75-1.5 Hz, which is determined to be the heart rate signal of the first user.
