[0025] In the embodiments of this disclosure, the detection module includes a receiver and multiple transmitters, among which a transmitter performs physiological detection based on time-of-flight. Different transmitters emit different signals. By combining the receiver and the transmitter performing physiological detection based on time-of-flight, physiological information is detected.

[0026] When a terminal device includes a time-of-flight (TOF) image acquisition unit, the TOF-based physiological detection transmitter is integrated into the image acquisition module. It can be used for both image acquisition and physiological information detection, thus realizing the multi-functionality of the TOF transmitter. The TOF transmitter enables the transmission of different signals, reducing the number of additional transmitters required for detection when using separate, separately assembled transmitters. This reduces the total space occupied by the transmitter and image acquisition unit, thereby reducing the overall space occupied by the detection module and image acquisition unit.

[0036] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0037] refer to Figure 1 This is a schematic diagram of the structure of a detection module, for reference. Figure 2 This is a schematic diagram of the electrical connection relationship of a detection module, combined with... Figure 1 and Figure 2 The detection module includes:

[0038] Multiple transmitters 1, each transmitting a different signal towards the object being tested. The multiple transmitters include at least one transmitter for physiological detection based on time-of-flight.

[0039] Receiver 2, with multiple transmitters 1 located around receiver 2, receiver is used to receive multiple reflected signals reflected back from multiple transmitted signals based on multiple transmitters.

[0040] The signal processing component 3 is connected to the transmitter 1 and the receiver 2 respectively, and is used to obtain the physiological detection results of the tested object based on the transmitted signal and the reflected signal.

[0041] This detection module can be applied to terminal devices, including mobile and fixed terminal devices. Mobile terminal devices can include mobile phones, tablets, in-vehicle central control devices, wearable devices, smart devices, and aircraft, while smart devices can include smart office equipment, smart home devices, and robots.

[0042] This detection module has the function of detecting the physiological information of the tested object, which can be a biological body, such as a human or animal. Transmitter 1 can be any transmitter capable of emitting signals for detecting physiological information; the model, specifications, and other parameters of transmitter 1 are not limited. The number of transmitters 1 must be at least two to improve the accuracy of the detection results.

[0043] Among the multiple transmitters 1 is a transmitter that performs physiological detection based on Time of Flight (TOF), which is capable of performing physiological detection and can transmit a signal for performing physiological detection.

[0044] The multiple transmitters 1 may also include other transmitters that emit their own transmission signals, respectively, as well as the transmitter that performs physiological detection based on time of flight.

[0045] Multiple different transmitters 1 transmit different signals, including but not limited to signals with different wavelengths.

[0046] For example, the transmitted signal is infrared light, and different transmitters 1 emit infrared light of different wavelengths, that is, different transmitters 1 emit infrared light of different wavelengths.

[0047] For example, multiple transmitters 1 can emit different infrared rays simultaneously.

[0048] For example, the transmitted signal may also include red light, green light or other colored light signals, or other electromagnetic wave signals, as long as the transmitter signals transmitted by different transmitters 1 are different.

[0049] Figure 1 Two transmitters are shown, namely a first transmitter 101 and a second transmitter 102, but more transmitters may be included.

[0050] The number of transmitters for time-of-flight physiological detection can be one or more. The number of transmitters for time-of-flight physiological detection can be determined based on the number of TOF-based image acquisition units. One TOF-based image acquisition unit may include one transmitter for time-of-flight physiological detection.

[0051] For example, the terminal device includes a Time-of-Flight (TOF) based image acquisition unit, which in turn includes a transmitter for physiological detection based on time-of-flight. As an image acquisition unit within the terminal device, the TOF-based image acquisition unit can emit infrared signals for ranging, thus fulfilling the functions of an image acquisition unit, such as determining depth information. It can also be used for physiological information detection, thereby realizing the functional purpose of a transmitter for physiological detection based on time-of-flight.

[0052] For example, there is usually one TOF-based image acquisition unit in the terminal device, so there is only one transmitter for physiological detection based on time of flight. This can realize the function of the TOF-based image acquisition unit, the function of transmitting signals for physiological detection, and reduce the space occupied by transmitter 1.

[0053] Receiver 2 is a receiver for the reflected signal of the transmitted signal, used to receive the reflected signal of the transmitted signal.

[0054] Multiple transmitters 1 are located around a receiver 2, which receives multiple reflected signals from multiple transmitted signals emitted by the multiple transmitters 1. That is, the receiver 2 can receive multiple reflected signals from multiple transmitted signals emitted by the multiple transmitters. For example, the receiver 2 can receive a first reflected signal from a first transmitted signal emitted by transmitter 11, a second reflected signal from a second transmitted signal emitted by transmitter 12, and a third reflected signal from a third transmitted signal emitted by transmitter 13.

[0055] Each transmitter emits a different signal, so the reflected signal of each transmitted signal is also different, and each transmitted signal has its own corresponding reflected signal. Each receiver 2 can receive reflected signals from multiple different transmitters.

[0056] The number of receivers 2 can be one or more. When there is only one receiver 2, it can receive reflected signals from at least two transmitters 1. When there are multiple receivers 2, each receiver 2 can also receive reflected signals from at least two transmitters 1.

[0057] Figure 1 A receiver 2 is shown, but more receivers can be included. The more receivers 2 there are, the more accurate the physiological test results will be.

[0058] For example, for at least one receiver 2, among the received multiple reflected signals, at least one reflected signal is a reflected signal of a transmitted signal emitted by a transmitter performing physiological detection based on time of flight. This allows physiological detection to be performed using the transmitter performing physiological detection based on time of flight.

[0059] For example, among the multiple reflected signals received by each receiver 2, there is at least one reflected signal of a transmitted signal emitted by a transmitter performing physiological detection based on time of flight.

[0060] Multiple transmitters 1 are located around receiver 2, which can include any arrangement of multiple transmitters 1 around receiver 2, including but not limited to: multiple transmitters 1 located on both sides of receiver 2, or multiple transmitters 1 distributed with receiver 2 as the center.

[0061] This arrangement facilitates the receiver receiving the reflected signals from each transmitter, thereby improving detection accuracy.

[0062] The signal processing component 3 can be any processing component capable of processing transmitted and reflected signals, and obtaining physiological information of the tested object based on the transmitted and reflected signals. This signal processing component 3 can be a processor, microprocessor unit, signal processing circuit, etc., capable of obtaining the aforementioned detection results.

[0063] For example, the signal processing component 3 can determine a first detection result based on the reflected signal received by any one of the receivers 2 and the transmitted signal emitted by the corresponding transmitter 1, and then determine a second detection result based on each of the first detection results, using the second detection result as the final detection result. Of course, the detection result can also be determined based on the transmitted signals emitted by each transmitter 1 and the reflected signals received by the receiver 2 in other ways.

[0064] The method for determining the first detection result may include: the wavelengths of the transmitted signals emitted by each transmitter are different, and the same receiver can receive the reflected signals corresponding to multiple transmitters, with different receivers receiving different reflected signals. After the same transmitted signal is reflected by the object being tested, the blood supply to the tested area due to the heartbeat will cause the blood in the tested area to reflect and absorb the transmitted signal differently at different times, resulting in different reflected signals. In this way, the first detection result can be determined by combining the transmitted signals from different transmitters.

[0065] The signal processing component 3 can also be connected to the central processing unit (CPU) in the terminal device where the detection module is located, be controlled by the central processing unit, and be able to interact with the central processing unit.

[0066] Physiological information can include heart rate, blood oxygen, and blood pressure, and the corresponding physiological test results are heart rate test result, blood oxygen test result, and blood oxygen test result, respectively.

[0067] When performing physiological information detection, such as heart rate detection or blood oxygen monitoring, the transmitter 1 and receiver 2 can be pointed towards the corresponding detection area of ​​the subject, such as the fingertip or wrist, or the distance between the detection module and the detection area of ​​the subject can be less than a preset detection distance. After multiple transmitters 1 emit transmission signals, the subject reflects each transmission signal, and the receiver 2 can then receive the reflected signals from the multiple transmitters 1.

[0068] When a terminal device includes a time-of-flight (TOF) image acquisition unit, the TOF-based physiological detection transmitter is integrated into the image acquisition module. It can be used for both image acquisition and physiological information detection, thus realizing the multi-functionality of the TOF transmitter. By combining the receiver and the TOF-based physiological detection transmitter, physiological information detection is achieved. The TOF transmitter transmits different signals, reducing the number of additional transmitters required for detection when using separate, separately assembled transmitters. This reduces the total space occupied by the transmitter and image acquisition unit, thereby reducing the overall space occupied by the detection module and image acquisition unit.

[0069] At the same time, the reduced number of additional transmitters also lowers costs and the extent to which modifications need to be made to the internal structure of the terminal equipment.

[0070] In addition, the image acquisition unit can be used for both image acquisition and physiological information detection, realizing the multi-functional use of the image acquisition unit.

[0071] In one embodiment, there is one receiver 2, and the image acquisition unit in the terminal device includes the receiver 2. That is, the receiver 2 and the transmitter for physiological detection based on time of flight form a time-of-flight image acquisition unit.

[0072] The working principle of the time-of-flight image acquisition unit is to measure distance by transmitting and receiving transmitted signals (such as infrared light). Therefore, the image acquisition unit also includes a receiver to receive the reflected signal of the transmitted signal.

[0073] When a time-of-flight image acquisition unit is included in the terminal device, the receiver within the image acquisition unit eliminates the need for an additional receiver, thus reducing costs and space requirements, and helping to reduce the size of the detection module. Integrating the detection module into the terminal device further reduces the internal space occupied by the module and minimizes the need to modify the device's internal structure.

[0074] Meanwhile, by utilizing the transmitter within the time-of-flight image acquisition unit, the ranging and physiological detection functions of the time-of-flight image acquisition unit are achieved while reducing the number of separately installed transmitters, further reducing costs. This also reduces the space occupied by additional receivers, contributing to a smaller overall size of the detection module. When the detection module is integrated into the terminal device, it helps reduce the internal space occupied by the detection module and minimizes the need to modify the terminal device's internal structure.

[0075] In one embodiment, transmitter 1 includes at least one transmitter for time-of-flight-based physiological detection, referred to as first transmitter 101. Transmitter 1 also includes a second transmitter 102, which is different from the first transmitter 101 for time-of-flight-based physiological detection. For example, the first transmitter 101 is a transmitter within a time-of-flight-based image acquisition unit, possessing both time-of-flight-based ranging functionality and the ability to emit transmission signals for physiological detection. The second transmitter 102 is a transmitter outside of the time-of-flight-based image acquisition unit.

[0076] With this setup, physiological information can be detected by combining the transmitter in the image acquisition module and the additional transmitter. This reduces the number of additional transmitters, lowers costs, and reduces the space occupied by the detection module. It also enables the first transmitter 101 to perform multiple functions.

[0077] In one embodiment, when transmitter 1 includes a first transmitter 101 and a second transmitter 102, the number of the first transmitter 101 and the second transmitter 102 is at least one. The more transmitters there are, the more accurate the physiological detection results will be.

[0078] In one embodiment, the receiver 2, the first transmitter 101, and the second transmitter 102 are located on the same plane. This facilitates the transmission of the transmitted signal and the reception of the reflected signal.

[0079] In one embodiment, the transmitting end of the first transmitter 101, the transmitter of the second transmitter 102, and the receiving end of the receiver are located on the same plane. Since the transmitting end is the part that emits the transmitted signal and the receiving end is the part that receives the reflected signal, this arrangement can help reduce the impact on the emitted signal and also help reduce the impact on the received reflected signal.

[0080] In one embodiment, the transmitting end of the first transmitter 101, the transmitter of the second transmitter 102, and the receiving end of the receiver face the same side of the detection module.

[0081] Since the transmitters all emit signals to the same side of the detection module, the object under test located on that side can be measured during testing. The object under test can block and reflect the emitted signals, thus facilitating the reception of the reflected signals. By arranging the transmitter 1 and receiver 2 in this way, it is easy to ensure that the receiver 2 can receive the reflected signals from the first transmitter 101 and the second transmitter 102, thereby improving the accuracy of the detection results.

[0082] For example, the transmitting end of the first transmitter 101, the transmitter of the second transmitter 102, and the receiving end of the receiver face the same side of the detection module, including:

[0083] The transmitter ports of the first transmitter 101, the second transmitter 102, and the receiver ports of the receiver all face the same direction.

[0084] In one embodiment, the transmitting end of the first transmitter 101, the transmitter of the second transmitter 102, and the receiving end of the receiver face the same side of the detection module, and may further include:

[0085] The transmitting end of the first transmitter 101, the transmitter of the second transmitter 102, and the receiving end of the receiver are oriented differently. However, in the detection scenario, the transmission signals transmitted by the first transmitter 101 and the second transmitter 102 can be blocked and reflected by the object under test, and the receiver 2 can receive the reflected signals of each transmission signal.

[0086] The above embodiments provide various relative positional relationships of the first transmitter 101, the second transmitter 102, and the receiver 2. This increases the number of ways to set up the transmitter 1 and the receiver 2, while reducing the impact on the transmitter 1 transmitting the signal and the receiver 2 receiving the reflected signal, thereby improving the accuracy of physiological test results.

[0087] The relative positions of the first transmitter 101, the second transmitter 102, and the receiver 2 can be any of the above-mentioned positions, or a combination of multiple positions, thereby increasing the flexibility of the layout.

[0088] In one embodiment, when receiver 2 is a receiver in a time-of-flight image acquisition unit, the time-of-flight image acquisition unit includes a first transmitter 101 and receiver 2, with receiver 2 located between a second transmitter 102 and the first transmitter 101.

[0089] In one embodiment, when there are multiple second transmitters 102, the second transmitters 102 are arranged around the image acquisition unit. The distance between the first transmitter 101 and the image acquisition unit is less than a first preset distance, which can be a distance in millimeters, such as less than 10 millimeters. This facilitates the reception of reflected signals.

[0090] In one embodiment, the distance between two adjacent transmitters 1, or between an adjacent transmitter 1 and a receiver 2, is less than a preset distance. The preset distance can be a distance in millimeters, such as less than 10 millimeters. This facilitates the reception of reflected signals.

[0091] In one embodiment, such as Figure 2As shown, there is one first transmitter 101, one second transmitter 102, and one receiver 2, with the receiver 2 located between the first transmitter 101 and the second transmitter 102. That is, there is one image acquisition unit, which includes one second transmitter 102 and one receiver 2, with the receiver 2 located between the first transmitter 101 and the second transmitter 102. Because the receiver 2 is located in the middle, this facilitates the reception of reflected signals.

[0092] In one embodiment, each transmitter 1 and receiver 2 can be fixed on the same first fixing plate inside the terminal device. The first fixing plate can be a motherboard or other fixing plate.

[0093] In one embodiment, the detection module may further include a support body, on which the transmitter 1 and receiver 2 can be fixed. The support body may include a second fixing plate or a bracket, etc.

[0094] In one embodiment, there are multiple receivers 2; each receiver 2 is capable of receiving at least two reflected signals. The signal processing component 3 is used to obtain the physiological detection results of the subject based on the at least two reflected signals received by each receiver.

[0095] Since each receiver 2 can receive multiple different reflected signals, the signal processing component 3 can determine an intermediate physiological detection result based on the reflected signals received by each receiver 2, and then determine the final physiological detection result based on multiple intermediate physiological detection results. The final physiological detection result can be determined using methods such as average value, maximum value, or minimum value, or other methods can be used. This helps improve the accuracy of the quantitative detection results.

[0096] The method for determining intermediate physiological test results can refer to the method for determining the first physiological test results in the above embodiments.

[0097] In one embodiment, Figure 3 This is a schematic diagram of a transparent cover, such as... Figure 4 This is a schematic diagram of another detection module, combined with... Figure 1 , Figure 3 and Figure 4 The detection module also includes:

[0098] The transparent cover B1 has a physiological detection area for the subject to act upon, such as... Figure 3 The y shown;

[0099] Multiple transmitters 1 and receivers 2 are located on the same side of the transparent cover plate B1 and are set in the physiological detection area of ​​the transparent cover plate B1;

[0100] Multiple transmission signals are emitted outward from the physiological detection area to the object being tested; receiver 2 receives the reflected signals passing through the physiological detection area.

[0101] The transparent cover plate B1 can serve as part of the outer shell of the detection module. One surface of the transparent cover plate B1 has a physiological detection area for the target object to act upon. This surface is opposite to the surface where the transmitter 1 and receiver 2 are located; that is, the physiological detection area is located on the outer surface of the transparent cover plate B1, while the transmitter 1 and receiver 2 are located on the inner side of the transparent cover plate B1. The outer surface of the transparent cover plate B1 is the side of the transparent cover plate B1 that faces away from the first transmitter 101, the second transmitter 102, and the receiver 2.

[0102] The outer surface of the transparent cover plate B1 is as follows Figure 3 The x shown.

[0103] Transmitter 1 and receiver 2 are located in the physiological detection area of ​​transparent cover B1, which facilitates the transmission of signals and the reception of reflected signals through the physiological detection area.

[0104] For example, the transmitting port of the first transmitter 101, the transmitting port of the second transmitter 102, and the receiving port of the receiver 2 face the physiological detection area in the transparent cover plate B1 and overlap with the physiological detection area. This facilitates the transmission of signals and the reception of reflected signals through the physiological detection area, reducing the impact on the transmission and reception signals.

[0105] By setting up a physiological detection area, users can easily determine the required position within the detection module when testing is needed, thereby improving the user experience.

[0106] In one embodiment, the size of the physiological detection area is matched to the size of the test site on the subject. This facilitates the subject placing the test site within the physiological detection area for testing, reduces movement of the test site during the testing process, and thus helps improve the accuracy of the examination.

[0107] For example, the transparent cover B1 may include a transparent lens, and may be made of glass or plastic.

[0108] For example, the physiological detection area can be formed by a groove, a protrusion, or a through hole. The shape of the groove can be referenced... Figure 3 The y shown.

[0109] In one embodiment, the physiological detection area is formed by an inward recess of the transparent cover plate B1, for example, forming a groove.

[0110] The transmitting ports of the first transmitter 101, the second transmitter 102, and the receiving port of the receiver 2 are aligned with the bottom of the same groove. The first transmitter 101 and the second transmitter 102 transmit their respective signals outward through the same groove, and the receiver 2 receives the reflected signals through the same groove.

[0111] The use of the same groove also helps the receiver 2 receive reflected signals from different transmitters 1, reducing the impact of reflected signals from each transmitter on the receiver 2, thereby improving the accuracy of the inspection results.

[0112] In one embodiment, the size of the groove opening matches the size of the test area on the object being tested. This facilitates the placement of the test area into the physiological testing zone, reducing movement of the test area during the testing process and thus helping to improve the accuracy of the examination.

[0113] In one embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, the transparent cover plate B1 includes the camera transparent cover plate B2 of the camera module B of the terminal device.

[0114] The transparent cover B1 of the detection module shares a single transparent cover with the camera module of the terminal device. By placing the detection module within the camera module of the terminal device, the volume occupied by both the detection module and the camera module can be reduced. Simultaneously, it makes it easier for users to determine the area to be detected, improving ease of use and user experience.

[0115] In one embodiment, the camera transparent cover plate B2 has a first through hole, and the transparent cover plate B1 is stacked on top of the camera transparent cover plate B2 and exposed to the outside through the first through hole. In this case, each transmitter 1 can emit a transmission signal through the first through hole, and the receiver 2 can receive a reflected signal through the first through hole.

[0116] This setup allows the camera cover plate B2 of the image acquisition module B to be retained without affecting the transparent cover plate B1 of the detection module, thus decoupling the transparent cover plate B1 of the detection module from the camera cover plate B2 of the image acquisition module and making it more modular.

[0117] In one embodiment, reference Figure 3 , Figure 3 It can also refer to the camera transparent cover plate B2 of the image acquisition module B, and the detection module is located in the image acquisition module B of the terminal device;

[0118] The camera transparent cover plate B2 of the image acquisition module B has a first through hole z, which at least partially overlaps with the transmission port of the first transmitter 101, the transmission port of the second transmitter 102 and the receiving port of the receiver 2.

[0119] The first transmitter 101 and the second transmitter 102 transmit their respective signals outward through the first through hole z, and the receiver 2 receives the reflected signal through the first through hole z.

[0120] Each transmitter 1 has a transmission port, and the second transmitter 102 also has a transmission port. The rest of the transmitter 1 and receiver 2 can be located inside the terminal device.

[0121] The first through-hole z can be a through-hole shared by the transmitting port of the first transmitter 101, the transmitting port of the second transmitter 102, and the receiving port of the receiver 2. This can reduce the influence of the outer casing on the transmitted and received signals, and facilitate the transmission of transmitted signals and the reception of reflected signals.

[0122] like Figure 3 As shown, the through hole z can include multiple through holes. The through hole z can also include through holes corresponding to the transmitting port of the first transmitter 101, the transmitting port of the second transmitter 102, and the receiving port of the receiver 2, such that the transmitting port of the first transmitter 101 overlaps with the first through hole z1, the transmitting port of the second transmitter 102 overlaps with the first through hole z2, and the receiving port of the receiver 2 overlaps with the first through hole z3.

[0123] In one embodiment, reference Figure 3 The through holes corresponding to the transmitting ports of the first transmitter 101, the transmitting port of the second transmitter 102, and the receiving port of the receiver 2 are located on the same surface x of the transparent cover plate B1. This arrangement facilitates layout and signal transmission and reception.

[0124] Each transmitter 1 has a through hole z on its surface x where the transmitter port and receiver 2 are located. The transmitter port of each transmitter 1 and the receiver port of each receiver 2 overlap with their respective through holes at least partially, which facilitates the transmission of signals and the reception of reflected signals.

[0125] In one embodiment, the transmitting end of the first transmitter 101, the transmitting end of the second transmitter 102, and the receiving end of the receiver 2 are located within a first through-hole. The transmitting end includes a transmitting port, and the receiving end includes a receiving port. This reduces the influence of the housing on the transmitted and received signals, facilitating the transmission of transmitted signals and the reception of reflected signals. For example, the first through-hole is a shared through-hole for the transmitting end of the first transmitter 101, the transmitting end of the second transmitter 102, and the receiving end of the receiver 2.

[0126] In one embodiment, reference Figures 1 to 4 , Figure 4 It can also be Figure 1 A cross-sectional schematic diagram of the structure shown.

[0127] This embodiment also provides a terminal device, including:

[0128] The housing has a second through hole;

[0129] In any of the above embodiments, the detection module is disposed in the second through hole, and outputs a transmitted signal to the outside through the second through hole, and receives a reflected signal through the second through hole.

[0130] The terminal equipment can include mobile terminal equipment and fixed terminal equipment. Mobile terminal equipment can include mobile phones, tablets, in-vehicle central control equipment, wearable devices, smart devices, and aircraft, while smart devices can include smart office equipment, smart home equipment, and robots.

[0131] For a description of the various components included in the detection module, please refer to the relevant embodiments in the above examples, and will not be repeated here.

[0132] The second through-hole at least partially overlaps with the transmission port of the first transmitter 101, the transmission port of the second transmitter 102, and the receiving port of the receiver 2. The first transmitter 101 and the second transmitter 102 transmit their respective transmission signals outward through the second through-hole, and the receiver 2 receives the corresponding reflected signals of the first transmitter 101 and the second transmitter 102 through the second through-hole.

[0133] This embodiment defines another positional relationship between the transmitter and receiver in the terminal device, which can be an area outside the image acquisition module, that is, the TOF-based image acquisition unit and the first transmitter 101 are located in the rear shell of the terminal device or on the edge of the terminal device.

[0134] For example, the back cover of the terminal device here may refer to Figure 1 The area outside of image acquisition module B shown.

[0135] In one embodiment, the surface of the frame may include side frames, top frames, bottom frames, etc. The image acquisition module is located on the frame of the terminal device, so that each of the first transmitters 101 and the second transmitters 102 and the receiver 2 are located on the same frame, thereby facilitating detection.

[0136] In one embodiment, the transmitting end of the first transmitter 101, the transmitting end of the second transmitter 102, and the receiving end of the receiver 2 are located within the second through hole. This reduces the influence of the housing on the transmitted and received signals, facilitating the transmission of the transmitted signal and the reception of the reflected signal. For example, the second through hole is a shared through hole for the transmitting end of the first transmitter 101, the transmitting end of the second transmitter 102, and the receiving end of the receiver 2.

[0137] For example, part of the detection module is located inside the terminal device, and the remaining part is located in the second through hole, such as the transparent cover plate B1 being located in the second through hole.

[0138] For example, the physiological detection area of ​​the detection module is exposed through a second through-hole, which makes it easier for users to determine the area to be acted on during detection, thereby improving convenience and user experience.

[0139] For example, the housing of the terminal device containing the detection module may include a back cover and a frame, with a second through-hole on the back cover or the frame. The physiological detection area of ​​the detection module is exposed through the second through-hole in the frame, or through the second through-hole in the back cover.

[0140] In one embodiment, reference Figure 1 and Figure 2 , Figure 1 It can also be a schematic diagram of a terminal device, which also includes:

[0141] Output component 4 is used to output the physiological detection results of the physiological information obtained by signal processing component 3.

[0142] In one embodiment, the output component includes at least one of the following:

[0143] The display screen is used to show the test results;

[0144] The indicator light is used to output illumination information. The illumination information of the indicator light has a first preset relationship with the detection result. Different illumination information indicates different detection results.

[0145] The speaker is used to output audio information. The audio information output by the speaker has a second preset relationship with the detection result. Different audio information represents different detection results.

[0146] In one embodiment, the lighting information includes at least: lighting frequency and / or color;

[0147] Audio information includes at least: audio content and / or volume.

[0148] In one embodiment, when the output component 4 is an indicator light, the illumination information of the indicator light includes at least: illumination frequency and / or color.

[0149] The detection results can include multiple states, such as normal and abnormal states. Different states correspond to different lighting information. A normal state can correspond to the first lighting frequency, the first lighting color, or both. An abnormal state can correspond to the second lighting frequency, the second lighting color, or both.

[0150] This allows the indicator light to show whether the test results are normal, making it easier for users to obtain the results.

[0151] In one embodiment, when the output component 4 is a speaker, the audio information includes at least: audio content and / or volume.

[0152] The detection results can include multiple states, such as normal and abnormal states. Different states correspond to different audio information. A normal state can correspond to the first audio content, the first volume, or both. An abnormal state can correspond to the second audio content, the second volume, or both.

[0153] This allows the audio information emitted by the speaker to indicate whether the test results are normal, making it easier for users to obtain the test results.

[0154] The output component is connected to the signal processing component 3 and is used to output the detection result. The output component 4 can be any device capable of outputting information, such as a display screen, indicator light, and speaker. Different output components may have different output methods, and the same detection result may be output in different ways through different output components.

[0155] For example, when output component 4 is a display screen, the display screen can be the display screen of the terminal device, and the terminal device's display screen can simultaneously serve as both the terminal device's display screen and a display screen for displaying detection information. The display screen can directly display the detection results, such as the corresponding values ​​for heart rate and blood oxygen, etc.

[0156] In one embodiment, reference Figure 5 This is a schematic diagram of a detection method, which includes:

[0157] S100 outputs multiple transmission signals to the object under test through multiple transmitters.

[0158] S200 receives multiple reflected signals from multiple transmitted signals based on multiple transmitters via a receiver.

[0159] The S300 processes the transmitted and reflected signals to obtain the physiological test results of the tested object.

[0160] The detection principle can be found in the description of the determination of the detection result in the corresponding embodiment of the detection module.

[0161] In one embodiment, the method of outputting multiple transmission signals to the object under test via multiple transmitters includes:

[0162] The physiological detection interface is displayed, and the first target operation acting on the physiological detection interface is detected. The first target operation is used to output a transmission signal. According to the first target operation, multiple transmitters are controlled to output multiple transmission signals toward the object being tested.

[0163] The physiological detection interface is used for detecting physiological information. The first target operation can be a user-defined operation or the default operation of the terminal device. After detecting the first target operation on the physiological detection interface, the terminal device can be switched to physiological information detection mode, controlling multiple transmitters to output multiple transmission signals towards the object being tested.

[0164] For example, the physiological detection interface includes a target control used for switching physiological information detection modes. Upon detecting a first target operation applied to the target control, multiple transmitters can be controlled to output multiple transmission signals towards the object being tested.

[0165] For example, the physiological testing interface can be user-defined or it can be the default interface of the terminal device.

[0166] For example, based on the first target operation, the target control can be switched to the on state, controlling multiple transmitters to output multiple transmission signals toward the object under test.

[0167] In one embodiment, the method further includes:

[0168] The detection operates on a second target operation on the physiological detection interface, wherein the second target operation is used to stop the output of the emission signal; and the second target operation controls multiple transmitters to stop outputting multiple emission signals toward the object being tested.

[0169] The second target operation can be a user-defined operation or a default operation of the terminal device. After the second target operation is detected in the physiological monitoring interface, the terminal device can be exited from the physiological information monitoring mode.

[0170] For example, the second target operation can be different from the first target operation, or it can be the same as the first target operation. The second target operation and the first target operation are used to switch the target control to different states, and the different states of the target control correspond to whether or not the physiological information detection mode is entered.

[0171] For example, according to the second target operation, the target control can be switched to the off state, controlling multiple transmitters to stop outputting multiple transmission signals to the tested object. The off state corresponds to exiting the physiological information detection mode.

[0172] In one embodiment, there are multiple receivers 2;

[0173] S300 processes the transmitted and reflected signals to obtain the physiological test results of the tested object, including:

[0174] S301, Based on at least two reflected signals and multiple transmitted signals received by each receiver, determine the intermediate detection result corresponding to each receiver;

[0175] S302, based on the intermediate detection results corresponding to each receiver, determine the physiological detection results of the tested object.

[0176] Each receiver 2 can receive reflected signals of transmitted signals from multiple transmitters, such as the first reflected signal of the first transmitted signal transmitted by transmitter 11, the second reflected signal of the second transmitted signal transmitted by transmitter 12, and the third reflected signal of the third transmitted signal transmitted by transmitter 13.

[0177] Each transmitter emits a different signal, so the reflected signal of each transmitted signal is also different, and each transmitted signal has its own corresponding reflected signal. Each receiver 2 can receive reflected signals from multiple different transmitters.

[0178] Based on the reflected signal received by any receiver 2 and the transmitted signal emitted by the corresponding transmitter 1, the first detection result corresponding to that receiver is determined. This allows us to determine the first detection result for each receiver, also known as the intermediate detection result. Then, the physiological detection result is determined based on these intermediate detection results. Alternatively, other methods can be used to determine the detection result based on the transmitted signals emitted by each transmitter 1 and the reflected signals received by each receiver 2.

[0179] The intermediate detection results can be determined by considering that the wavelengths of the transmitted signals emitted by different transmitters are different, and the same receiver can receive the reflected signals from multiple transmitters, resulting in different reflected signals received by different receivers. When the same transmitted signal is reflected by the object being tested, the blood flow to the tested area due to the heartbeat will cause variations in the reflection and absorption of the transmitted signal by the blood at different times, resulting in different reflected signals. Therefore, the intermediate detection results can be determined by combining the transmitted signals from different transmitters.

[0180] The physiological test results of the test subject can be determined based on the intermediate test results. The average, maximum or minimum value of the intermediate test results can be used to determine the physiological test results of the test subject. Other methods can also be used to determine the physiological test results, and there are no limitations.

[0181] This method can improve the accuracy of physiological test results and enhance the user experience.

[0182] In one embodiment, reference Figure 6 This is a schematic diagram of a detection device, which includes:

[0183] The output module 10 is used to control multiple transmitters to transmit transmission signals for physiological information detection in the physiological information detection mode; wherein the multiple transmitters include: at least one first transmitter; a time-of-flight image acquisition unit; the image acquisition unit includes a second transmitter; and the transmission signals transmitted by different transmitters are different.

[0184] The receiving module 20 is used to receive the reflected signal of the transmitted signal transmitted by the first transmitter and the second transmitter through at least one receiver;

[0185] The processing module 30 is used to obtain the detection results of the physiological information of the object being tested based on the transmitted signal and the reflected signal.

[0186] In one embodiment, the apparatus further includes:

[0187] Output module 40 is used to output the detection results.

[0188] In one embodiment, the output module 10 includes:

[0189] The display unit is used to display the physiological detection interface;

[0190] A first detection unit is used to detect a first target operation acting on the physiological detection interface, wherein the first target operation is used to output the transmission signal;

[0191] A first control unit is configured to control a plurality of transmitters to output a plurality of transmission signals toward the object under test, according to the first target operation.

[0192] In one embodiment, the apparatus further includes:

[0193] The detection module is used to detect a second target operation acting on the physiological detection interface, wherein the second target operation is used to stop outputting the transmission signal;

[0194] The control module is used to control the plurality of transmitters to stop outputting the plurality of transmission signals toward the object under test according to the second target operation.

[0195] In one embodiment, reference Figure 4 Another type of terminal device is also provided, including:

[0196] The TOF laser module a includes a first infrared emitter (which continuously emits infrared signal 1 and receives two sets of signals);

[0197] Protective and supportive shielding cover b (supporting foam and protective devices);

[0198] Foam c (isolates the emitted signal under the lens to ensure data accuracy);

[0199] Second infrared transmitter 102 (continuously emits infrared signal 2);

[0200] Lens B1;

[0201] FPC (flexible or rigid board) e (the carrier connecting the device to the motherboard).

[0202] The TOF laser module a, protective / support shield b, and second emitter 102 (such as an infrared emitter) are fixed to the FPC flexible board or rigid board e by surface mount soldering. Foam c is insulated between the protective and support shield b and the transparent cover plate B1. The FPC flexible board or rigid board e is directly connected to the motherboard.

[0203] Working Principle: The Time-of-Flight (TOF) continuously emits infrared signal 1, while the infrared module continuously emits infrared signal 2. After absorption and reflection by the finger, the receiver in the TOF can continuously receive both infrared signals. The test subject's heart rate can be determined based on the transmission and reception intensity data of one signal. The wavelengths and / or intensities of the transmitted signals emitted by the first and second transmitters are different, and different first transmitters emit signals with different wavelengths and / or intensities. The same receiver can receive the reflected signals corresponding to the first and second transmitters respectively, and different receivers receive different reflected signals. After the same transmitted signal is reflected by the test subject, the heartbeat provides blood to the test site. The reflection and absorption of the transmitted signal by the blood in the test site varies at different times, resulting in different reflected signals. Thus, the detection result can be determined by combining the transmitted signals from different transmitters. This scheme uses two different wavelengths of infrared light for testing, obtaining two sets of data. Based on these two sets of data, a more accurate continuous heart rate fluctuation can be fitted.

[0204] The terminal device in this embodiment has the following advantages: 1. The TOF module and IR module are small in size and can be placed closer, making finger measurement more convenient; 2. Improved heart rate measurement accuracy; 3. When measuring heart rate, the finger is on the back of the phone and the user's line of sight is also on the back of the phone, avoiding the finger from slipping out of the measurement area; 4. The heart rate can be displayed and fed back in real time during measurement; (can be applied to small folding screens and tri-folding screens).
