The wearable device 100 may control the light source transmitter to output an initial light signal according to a preset power, and obtain an initial electrical signal converted based on the light signal reflected by the initial light signal, and adjust the preset power when the initial electrical signal is not within a preset interval, so as to use the adjusted preset power as a target power.

FIG. 2 is a flow chart of a signal processing method in one embodiment. The signal processing method in this embodiment is described taking the wearable device in fig. 1 as an example. As shown in fig. 2, the signal processing method includes steps 202 to 208.
Step 202, controlling the light source transmitter to output an initial light signal according to a preset power.
The wearable device includes a light source emitter. A light source emitter refers to a device capable of outputting an optical signal. The optical signals may be applied in various scenarios, such as electrocardiographic detection, heart rate detection, ranging, communication, etc. Power is a parameter related to the energy of the light signal emitted by the light source emitter. The higher the power is, the larger the energy of the optical signal output by the light source emitter is, and the larger the power consumption of the light source emitter is; conversely, the lower the power, the less the light signal energy output by the light source emitter, and the lower the power consumption of the light source emitter.
The preset power is a power stored in advance by the wearable device for outputting the initial light signal. Optionally, the preset power may be any one of the powers that the light source emitter can provide, for example, may be an intermediate value in the powers that the light source emitter can provide; the power with highest detection accuracy can be obtained according to experimental data; the power may be set according to a preset power selected by a user, and the like, and is not limited herein. The initial optical signal is an optical signal output by the wearable device according to preset power.
The wearable device may control the light source transmitter to output an initial light signal at a preset power. Specifically, the wearable device may receive a correction instruction for the optical signal, and control the light source transmitter to output an initial optical signal according to a preset power according to the correction instruction. The correction instruction is an instruction for adjusting the light signal output by the light source transmitter in the wearable device. Optionally, the correction instruction may be according to a touch operation of the wearable device by the user; or may be generated by monitoring operation information of the wearable device, etc., after the operation information, etc., satisfies a preset condition.
Step 204, obtaining an initial electrical signal corresponding to the initial optical signal, where the initial electrical signal is converted based on the optical signal reflected by the initial optical signal.
The initial electrical signal is an electrical signal corresponding to the initial optical signal. In particular, the wearable device may incorporate a photosensitive sensor to receive the reflected light signal and convert the reflected light signal into an electrical signal.
In step 206, when the initial electrical signal is not within the preset interval, the preset power is adjusted.
The preset interval is an electric signal interval corresponding to the optical signal which can meet the application requirement. Specifically, the preset interval may be determined according to a specific application scenario and an optical signal detection range of the photosensitive sensor, which is not limited herein. For example, when the electrical signal corresponding to the optical signal satisfying the application requirement is 0.1A to 2A, the corresponding preset interval may be greater than or equal to 0.1A; or greater than 0.05A and less than or equal to 2A; and may be greater than or equal to 0.1A and less than 3A, etc., without limitation.
When the initial electrical signal is not in the preset interval, the initial optical signal output according to the preset power is not satisfied with the application requirement, and the wearable device can adjust the preset power. Typically, the initial electrical signal is not a fixed value, as affected by the reflectivity of the surrounding environment of the wearable device, alternatively the wearable device may determine whether the initial electrical signal is within a preset interval by averaging, mode, median, etc. The wearable device adjusts the preset power, optionally, the wearable device can determine an adjustment value of the preset power according to a difference value between the initial electric signal and a preset interval so as to adjust the preset power; the wearable device may also successively increase or decrease the preset power until the initial electrical signal converted based on the initial electrical signal output according to the adjusted preset power is within the preset interval.
And step 208, taking the adjusted preset power as the target power.
The wearable device takes the adjusted preset power as target power, and can control the light source transmitter to output a target light signal according to the target power. The energy of the target optical signal may meet the application requirements of the optical signal. Specifically, the wearable device may configure the light source transmitter according to the target power, so that the configured light source transmitter may output the target light signal according to the target power. Alternatively, when the initial electrical signal is within the preset interval, the preset power may be directly used as the target power.
Further, after the adjusted preset power is taken as the target power, the wearable device can receive a detection instruction based on the optical signal, control the light source emitter to output a target optical signal corresponding to the target power according to the detection instruction, so as to obtain a target electric signal converted based on the optical signal reflected by the target optical signal, and output a detection result corresponding to the detection instruction according to the target electric signal. For example, when the detection instruction based on the optical signal is a ranging detection instruction, the wearable device may determine the distance of the measured object based on the target electrical signal converted from the optical signal reflected by the target optical signal; when the detection instruction based on the optical signal is an electrocardiographic detection instruction, the wearable device can analyze and output a corresponding electrocardiographic detection chart based on the target electrical signal converted by the optical signal reflected by the target optical signal.
According to the signal processing method provided by the embodiment of the application, the initial optical signal is output according to the preset power by controlling the light source transmitter, the initial electric signal converted based on the optical signal reflected by the initial optical signal is obtained, when the initial electric signal is not in the preset interval, the preset power is adjusted, the adjusted preset power is used as the target power, the target optical signal output according to the target power can meet the application requirement, the accuracy of the target optical signal and the target power can be improved, the problems of poor application effect, inaccurate detection and the like caused by the fact that the output optical signal does not meet the application requirement are avoided, and the application effect of the optical signal is optimized.
In one embodiment, step 206 includes: when the initial electric signal is smaller than the minimum value of the preset interval, increasing the preset power, and returning to the step of controlling the light source transmitter to output the initial light signal according to the preset power until the initial electric signal is in the preset interval; step 202 comprises: and controlling the light source emitter to output an initial light signal according to the increased preset power.
The predetermined interval includes a minimum value. For example, when the preset interval is greater than or equal to 0.06A, the minimum value of the preset interval is 0.06A; when the preset interval is more than 0.8A and less than 2A, the minimum value of the preset interval is 0.8A.
When the initial electrical signal is smaller than the minimum value of the preset interval, the energy of the initial optical signal at the moment cannot meet the application requirement. The wearable device increases preset power, specifically, the wearable device is preset with power corresponding to energy levels of different optical signals, the preset power can be gradually increased according to the power corresponding to the energy levels of the different preset optical signals and the current preset power, after the preset power is increased, the light source transmitter is controlled to output an initial optical signal according to the increased preset power, and an initial electrical signal corresponding to the initial optical signal is obtained until the initial electrical signal is stopped after being in a preset interval.
For example, the wearable device is preset with power corresponding to energy levels of three light signals of 0.05W, 0.08W and 0.1W respectively; if the current preset power is 0.6W, the initial electric signal corresponding to the initial optical signal output by the light source transmitter according to 0.6W is smaller than the minimum value of the preset interval, the wearable device can increase the preset power to 0.08W, and control the light source transmitter to output the initial optical signal according to 0.08W, and when the initial electric signal corresponding to the initial optical signal is within the preset interval, the target power can be set to 0.08W; when the initial optical signal is still smaller than the preset interval, the preset power can be increased again until the initial electrical signal corresponding to the initial optical signal output according to the preset power is in the preset interval. Optionally, the wearable device may also adjust the preset power according to a preset adjustment amplitude. For example, the preset adjustment range may be 0.05W, 0.1W, 0.2W, 0.3, or the like, without being limited thereto.
By gradually increasing the preset power until the initial electrical signal corresponding to the initial optical signal output according to the preset power is in the preset interval, the adjusted preset power is used as the target power, so that the target optical signal output according to the target power can be ensured to meet the application requirement, the accuracy of the target power can be improved, the problem of larger power consumption caused by overlarge target power can be avoided by gradually increasing the preset power, and the power consumption of the optical signal during application can be reduced.
Fig. 3 is a flowchart of a signal processing method in another embodiment. As shown in fig. 3, in one embodiment, a signal processing method is provided that includes:
step 302, controlling the light source transmitter to output an initial light signal according to a preset power.
Step 304, an initial electrical signal corresponding to the initial optical signal is obtained, where the initial electrical signal is converted based on the optical signal reflected by the initial optical signal.
Step 306, judging whether the initial electrical signal is smaller than the minimum value of the preset interval; when the initial electrical signal is less than the minimum value of the preset interval, go to step 308; when the initial electrical signal is not less than the minimum value of the preset interval, step 312 is entered.
Step 308, circularly executing the operation of increasing the preset power, controlling the light source emitter to output an initial light signal according to the increased preset power, and obtaining an initial electric signal corresponding to the initial light signal until the initial electric signal is within a preset interval.
And step 310, taking the adjusted preset power as the target power.
Step 312, the operation of decreasing the preset power is performed in a circulating manner, and the light source transmitter is controlled to output the initial light signal according to the decreased preset power until the initial electric signal is less than or equal to the minimum value of the preset interval.
The initial electrical signal not smaller than the minimum value of the preset interval may be within the preset interval or may be outside the preset interval. For example, when the preset interval is greater than 1A and less than 3A, the electric signal of the minimum value not less than the preset interval may refer to the electric signal in the preset interval such as 1.2A, 1.5A, 2A, etc., or may refer to the electric signal in the preset interval such as 3.5A, 4A, etc; when the preset interval is a half-open interval such as more than 1A, the electric signals with the minimum value not less than the preset interval are all in the range of the preset interval.
Similarly, the wearable device may preset each reduced power amplitude; when the initial electric signal is determined not to be in the preset interval, gradually reducing the preset power until the initial electric signal corresponding to the initial optical signal output according to the reduced preset power is smaller than the minimum value of the preset interval.
And step 314, taking the reduced preset power which is greater than or equal to the minimum value of the preset interval and is the minimum value as the target power.
The wearable device can obtain a plurality of reduced preset powers in the process of circularly executing the operation of reducing the preset power and controlling the light source transmitter to output the initial light signal according to the reduced preset power until the initial electric signal is smaller than or equal to the minimum value of the preset interval, and the wearable device can take the reduced preset power which is larger than or equal to the minimum value of the preset interval and is the minimum value as the target power, and the power of the light source transmitter outputting the initial light signal in the last cycle of ending the cycle is taken as the target power. For example, when the preset power is 0.7W, the initial electrical signal is not less than the minimum value of the preset interval, and if the wearable device gradually reduces the preset power to 0.5W, 0.4W, 0.2W, 0.1W; when the preset power is 0.1W, the corresponding initial electrical signal is smaller than the minimum value of the preset interval, and the power which is larger than or equal to the minimum value of the preset interval and is the minimum power, namely 0.2W, can be used as the target power.
Gradually increasing preset power when the initial electric signal is smaller than the minimum value of the preset interval until the initial electric signal corresponding to the initial optical signal output according to the increased preset power is in the preset interval, and taking the adjusted preset power as target power; and gradually reducing the preset power when the initial electric signal is not smaller than the minimum value of the preset interval until the initial electric signal corresponding to the initial optical signal output according to the reduced preset power is smaller than the minimum value of the preset interval, and taking the power which is larger than or equal to the minimum value of the preset interval and is the minimum power as the target power, so that the power consumption can be reduced while the accuracy of the target power is ensured and the application effect of the optical signal is optimized.
Fig. 4 is a flowchart of a signal processing method in yet another embodiment. As shown in fig. 4, in one embodiment, a signal processing method is provided that includes:
step 402, controlling the light source transmitter to output an initial light signal according to a preset power.
Step 404, acquiring an initial electrical signal corresponding to the initial optical signal, wherein the initial electrical signal is converted based on the optical signal reflected by the initial optical signal.
Step 406, judging the relation between the initial electric signal and the preset interval; when the initial electrical signal is less than the minimum value of the preset interval, go to step 408; when the initial electrical signal is greater than the maximum value of the preset interval, go to step 410; when the initial electrical signal is not less than the minimum value of the preset interval and not greater than the maximum value of the preset interval, step 414 is entered.
Step 408, circularly executing the operation of increasing the preset power, controlling the light source emitter to output an initial light signal according to the increased preset power, and obtaining an initial electric signal corresponding to the initial light signal until the initial electric signal is within the preset interval.
Step 410, cyclically executing the operation of reducing the preset power, controlling the light source emitter to output an initial light signal according to the reduced preset power, and obtaining an initial electrical signal corresponding to the initial light signal until the initial electrical signal is within a preset interval.
In this embodiment, the predetermined interval includes a maximum value. For example, the preset interval may be greater than 1A and less than 3A; more than 0.5A and less than 4A; greater than 2A and less than or equal to 5A, etc., without limitation.
The initial electrical signal is greater than the maximum value of the preset interval, which indicates that the energy of the initial optical signal output according to the preset power exceeds the range of application requirements. The wearable device can gradually reduce the preset power when determining that the initial electrical signal is larger than the maximum value of the preset interval, and control the light source transmitter to output the initial optical signal according to the reduced preset power until the initial electrical signal corresponding to the initial optical signal is in the preset interval. The manner in which the wearable device reduces the preset power is similar to the manner in which the preset power is increased, and will not be described in detail herein.
And step 412, taking the adjusted preset power as the target power.
When the initial electric signal is larger than the maximum value of the preset interval, the wearable device can gradually reduce the preset power until the initial electric signal corresponding to the reduced preset power is in the preset interval, and the reduced preset power is used as the target power; when the initial electrical signal is smaller than the minimum value of the preset interval, the wearable device can gradually increase the preset power until the initial electrical signal corresponding to the increased preset power is in the preset interval, and the increased preset power is used as the target power.
Step 414, the operation of decreasing the preset power and controlling the light source emitter to output the initial light signal according to the decreased preset power is performed circularly until the initial electrical signal is less than or equal to the minimum value of the preset interval.
In step 416, the minimum preset power greater than or equal to the minimum value of the preset interval is set as the target power.
In the embodiment provided by the application, different power adjustment modes are adopted according to the relation between the initial electric signal and the preset interval, so that the target power can be ensured to be in the preset interval, the application effect of the optical signal is improved, and the power consumption of the optical signal output by the optical source transmitter is reduced.
Fig. 5 is a flow chart of a signal processing method in one embodiment. As shown in fig. 5, in one embodiment, a signal processing method is provided that includes:
step 502, controlling the light source transmitter to output an initial light signal according to a preset power.
Step 504, obtaining an initial electrical signal corresponding to the initial optical signal, the initial electrical signal being converted based on the optical signal reflected by the initial optical signal.
In step 506, when the initial electrical signal is not within the preset interval, a predicted electrical signal is obtained, and the predicted electrical signal is converted based on the initial optical signal.
The predicted electrical signal is an electrical signal based on the initial optical signal conversion. Specifically, the optical signal reflected by the initial optical signal is affected by the external environment and has a certain energy loss, so that the energy of the reflected optical signal is smaller than that of the initial optical signal, and the predicted electrical signal converted based on the initial optical signal is larger than the initial electrical signal converted based on the optical signal reflected by the initial optical signal. The wearable device may pre-store predicted electrical signals corresponding to the initial optical signals at different power outputs.
Step 508, a signal difference between the initial electrical signal and the predicted electrical signal is determined.
The wearable device may subtract the initial electrical signal from the predicted electrical signal to obtain the signal difference. The signal difference may reflect the degree of energy loss when the initial optical signal is affected by the external environment. The larger the signal difference value is, the larger the energy loss of the optical signal is; conversely, the smaller the signal difference, the smaller the energy loss of the optical signal.
Step 510, obtaining a corresponding power adjustment amplitude according to the signal difference, and adjusting the preset power according to the power adjustment amplitude.
Specifically, the wearable device may pre-store power adjustment amplitudes corresponding to different signal differences, so that the corresponding power adjustment amplitudes may be obtained according to the determined signal differences. Optionally, the wearable device may also pre-store an amplitude adjustment algorithm, so that substituting the signal difference value into the amplitude adjustment algorithm may obtain a corresponding power adjustment amplitude.
And step 512, taking the adjusted preset power as the target power.
The wearable device can adjust the preset power according to the obtained power adjustment amplitude, and takes the adjusted preset power as the target power. For example, when the preset power is 1W, if the power adjustment amplitude is increased by 0.5W, the target power is 1.5W; if the adjustment amplitude is reduced by 0.2W, the target power is 0.8W.
The power adjustment efficiency can be improved by determining the signal difference between the initial electric signal and the predicted electric signal, acquiring the corresponding power adjustment amplitude according to the signal difference, adjusting the preset power, and taking the adjusted preset power as the target power.
In one embodiment, the signal processing method provided in the present invention further includes, before controlling the light source transmitter to output the initial light signal according to the preset power: detecting environment information of the wearable equipment; determining whether the wearable device is converted from a detached state to a wearing state according to the environment information; when it is determined that the wearable device is converted from the detached state to the worn state, an operation of controlling the light source transmitter to output an initial light signal according to a preset power is performed.
The environmental information may include temperature information, location information, distance information from the human body, and the like. Specifically, the wearable device may detect environmental information in which the wearable device is located through a built-in sensor or other functional module. For example, the wearable device may determine the distance between the wearable device and the human body through infrared detection, or ultrasonic detection, or the like; temperature information around the wearable device is detected by a temperature sensor, etc. Alternatively, the wearable device may receive environmental information detected by the connected mobile terminal. For example, the wearable device may determine whether the wearable device and the human body are in the same position according to the position information of the wearable device and the position information of the mobile terminal, and the method is not limited herein.
The wearable device can determine whether the wearable device is worn or not by analyzing the environmental information, and when the wearable device is determined to be converted from the detached state to the wearing state, the operation of controlling the light source transmitter to output the light signal according to the preset power is executed.
The optical signal may be applied to detect sign information. Specifically, when the wearable device is worn on a human body, an optical signal may be output, and a signal reflected by the human body may be received to output a physical sign detection result. The loss of energy of the light signal reflected by the human body is often different due to the influence of tightness degree of wearing the wearable device by the human body, skin color, body hair and the like of the human body. When the wearable equipment is detected to be converted from the disengagement state to the wearing state, the light source transmitter is controlled to output an initial light signal according to the preset power, whether the preset power is regulated or not is determined according to the initial electric signal converted from the reflected light signal, and the target power is determined, so that the problem that the light signal requirement of sign detection is not met due to the fact that the uniform power is adopted to output the light signal, the energy of the reflected light signal is too low due to the fact that the worn human body changes or the wearing tightness degree is too low, and the accuracy of sign information detection is caused can be improved.
In one embodiment, the signal processing method provided may further include: analyzing a target tightness level of the wearable equipment in a wearing state according to the environmental information; and obtaining the preset power corresponding to the target tightness level from the corresponding relation between the preset tightness level and the power.
The tightness level of the wearable device may be determined according to the distance between the wearable device and the human body. The smaller the distance, the tighter the wearing is stated; the greater the distance, the more loosely the description is worn. The wearable device can preset tightness levels corresponding to different distances.
Specifically, the wearable device can acquire the distance between the wearable device and the human body through infrared detection and other modes, determine the target tightness level when the wearable device is in a wearing state according to the distance, acquire preset power corresponding to the target tightness level from the corresponding relation between the preset tightness level and power, and control the light source transmitter to output an initial light signal according to the preset power so as to determine whether to adjust the preset power according to the electric signal converted by the reflected light signal. In general, the more loosely the wearable device is worn, the greater the energy loss upon reflection of the light signal, otherwise the same; to ensure that the energy of the reflected optical signal can meet the requirements of sign detection, the light source transmitter needs to output the optical signal with greater power.
The corresponding preset power is obtained according to the target tightness level of the wearable equipment in the wearing state, the light source transmitter is controlled to output an initial light signal according to the preset power, whether the preset power is adjusted or not is determined according to the electric signal converted by the reflected light signal, accuracy of the preset power can be improved, and the adjustment times of the power are reduced.
FIG. 6 is a flow chart of a signal processing method in one embodiment. As shown in fig. 6, in one embodiment, a signal processing method is provided that includes:
step 602, controlling the light source transmitter to output an initial light signal according to a preset power.
In step 604, the optical signal reflected based on the initial optical signal is subjected to photoelectric conversion, and the direct current signal in the converted electrical signal is used as the initial electrical signal.
Because the absorption degree of the light may be changed in the external environment, the electrical signal obtained by performing photoelectric conversion on the optical signal reflected by the initial optical signal by the wearable device may include an ac signal and a dc signal. The wearable device may use the direct current signal of the converted electrical signal as an initial electrical signal.
In step 606, when the initial electrical signal is not within the preset interval, the preset power is adjusted.
And 608, taking the adjusted preset power as the target power.
In step 610, a sign detection instruction is received.
The wearable device may adjust the preset power to determine the target power when transitioning from the disengaged state to the worn state. The sign detection instruction can be generated by pressing a designated button of the wearable device, can be generated by touching a control displayed by the wearable device, can be generated by analyzing received voice information, and the like. Alternatively, the sign detection command may include an electrocardiographic detection command, a heart rate detection command, or a sign detection command that may be detected using an optical signal, which is not limited herein.
Step 612, controlling the light source transmitter to output a target light signal according to the target power according to the sign detection instruction.
The target power is the power obtained after the preset power is adjusted according to the initial electric signal. After the wearable device determines the target power, the wearable device can receive the sign detection instruction, and control the light source emitter to output a target light signal according to the target power according to the sign detection instruction so as to detect sign information of a human body.
In step 614, the optical signal reflected based on the target optical signal is photoelectrically converted, and the ac signal in the converted electrical signal is used as the target electrical signal.
Specifically, in this embodiment, the alternating current signal in the electric signal converted from the target optical signal may reflect the sign information of the human body. The wearable device may acquire, as the target electrical signal, an alternating-current signal of the electrical signals converted from the optical signal reflected based on the target optical signal.
FIG. 7 is a schematic diagram of sign detection by optical signals in one embodiment. As shown in fig. 7, the wearable device may perform electrocardiograph or heart rate detection through an optical signal, and send the optical signal through the light source transmitter 710, when the optical signal irradiates the skin of the human body, the reflection of the optical signal is affected due to the contraction and expansion of the blood vessel when the human body heartbeats, and when the optical signal is reflected back to the photosensitive sensor 720 of the wearable device through the skin tissue of the human body, the optical signal is attenuated to a certain extent; since the pulse of the blood vessel causes the absorption amplitude of the optical signal to change while the absorption of the optical signal by other tissues is basically unchanged, the reflected optical signal-converted electrical signal contains an alternating current signal corresponding to the pulse of the blood vessel and a direct current signal corresponding to other tissues. The ac signal corresponding to the vascular pulsation may be used as a target electrical signal to analyze the physical sign of the human body; the dc signals corresponding to other tissues may be used as initial electrical signals to determine whether to adjust the power of the light source emitters.
Step 616, determining a detection result corresponding to the sign detection instruction according to the target electrical signal.
The detection results corresponding to different sign detection instructions are different. The wearable device can analyze the target electrical signal according to the sign detection instruction to determine a corresponding detection result. For example, when the sign detection instruction is an electrocardiographic detection instruction, the wearable device may analyze according to the target electrical signal to obtain an electrocardiogram corresponding to the electrocardiographic detection instruction, and output the electrocardiogram; when the sign detection instruction is a heart rate detection instruction, the wearable device can determine a heart rate value of the human body according to the target electric signal and output the heart rate value.
Whether the preset power is adjusted or not is determined through the initial electric signal so as to determine the target power, and the optical signal is output according to the target power so as to perform physical sign detection, so that the accuracy of physical sign detection can be improved. In addition, the DC signal in the electric signal is extracted as an initial electric signal, so that the convenience of power adjustment can be improved.
