Detailed Description
The technical scheme of the application will be described below with reference to the accompanying drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Hereinafter, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first", "a second", etc. may explicitly or implicitly include one or more such feature.
In order to reduce the workload of a detector for setting the luminous intensity of the luminous device, the setting process is more convenient, and the accuracy of blood oxygen detection is improved, the embodiment of the application provides a parameter determining method, a parameter determining device and a controller of blood oxygen detection equipment.
The parameter determining method of the blood oxygen detecting device provided by the embodiment of the application can be applied to a controller of the blood oxygen detecting device, wherein the controller can be a microprocessor, a computer, a mobile phone, a smart watch and other devices with data processing, operation, sending and receiving functions, and can also be other devices with the functions.
As shown in fig. 1, 3 and 4, the blood oxygen detecting apparatus in the embodiment of the present application includes: the controller 110, the light emitter 130 and the receiver 140, the controller 110 is respectively in communication connection with the receiver 140 and the light emitter 130. The receiver 140 is configured to receive an optical signal emitted by the light emitter 130 and convert the optical signal into an electrical signal, where the light emitter 130 may be a red light emitter 130 or an infrared light emitter 130, or may be the light emitter 130 capable of emitting other light. The type of the receiver 140 corresponds to the type of the light emitter 130, for example, if the light emitter 130 is an infrared light emitter 130, the receiver 140 is also a device capable of receiving infrared light. The light emitter 130 and the receiver 140 are fixed on a wearing structure 160, and the wearing structure 160 is used for wearing a part to be detected by a user.
Optionally, the wearing structure 160 may be provided with a detector 170 for detecting the shape of the wearing structure 160, and the controller 110 is communicatively connected to the detector 170.
The wearing structure 160 may be a structure that can be worn on a portion to be detected of a user, such as a clip member, a band, a finger stall, a head cover, and a clip, and the specific form of the wearing structure is not limited. The light emitter and the receiver are fixed on the wearing structure, so that the light emitter and the receiver are more convenient for users to use.
As shown in fig. 2, the method for determining parameters of the blood oxygen detection device according to the embodiment of the present application includes the following steps S210 to S230:
step S210: and acquiring the morphological information of the wearing structure.
It will be appreciated that when the parts to be detected of the user are different, or when different users use the blood oxygen detecting apparatus, the thickness, the size, etc. of the parts to be detected are different, and the form of the wearing structure is different after the user wears the wearing structure. For example, when the wearing structure is a clip member, the opening angle of the clip member to the adult's finger is different from the opening angle to the infant's finger, and when the wearing structure is a headgear, the amount of headgear deformation is also different between the headgear fitting on the adult's head and the headgear fitting on the infant's head. The form of the wearing structure corresponds to a specific structure of the wearing structure, for example, if the wearing structure is a clamping member, the form of the wearing structure may be an opening angle of the clamping member, if the wearing structure is a strap, the form of the wearing structure may be a binding length of the strap, if the wearing structure is a finger stall, the form of the wearing structure may be a deformation amount of the finger stall, or the like. It is also understood that the configuration of the wearing structure is different when the wearing structure is worn at different locations to be detected.
The detector 170 may be a detector capable of detecting the shape of the wearing structure, and the type of the detector 170 may be determined according to the shape of the wearing structure 160, for example, the shape of the wearing structure 160 is the opening angle of the clamping member, and the detector 170 may be an angle detector. Embodiments of the present application are not limited to a particular type of detector 170.
For example, as shown in fig. 3, the blood oxygen detecting device may be a clip-on device, the corresponding wearing structure 160 being a clip-on member, and the morphological information being an opening angle of the clip-on member. In this case, the detector 170 may be an angle detector for detecting the opening angle of the holding member.
For another example, the blood oxygen measurement device may be a coat-type device, and the corresponding wearing structure 160 is an elastic sleeve, and the morphological information is a deformation amount of the elastic sleeve. In this case, the detector 170 may be an elastic deformation detector for detecting the deformation amount of the elastic sleeve.
As another example, as shown in fig. 4, the blood oxygen detection device is a band type device, the corresponding wearing structure 160 is a band, and the morphological information is a binding length of the band. In this case, the detector 170 may be a strap length detector for detecting a strap length of the strap.
Step S220: and determining the luminous intensity corresponding to the morphological information.
Specifically, the light emission intensity corresponding to the form information may be determined according to a preset correspondence between the form information and the light emission intensity.
It can be understood that when the wearing structure is worn at different positions to be detected, the wearing structure has different shapes, and in this embodiment, the corresponding relationship between the preset shape information and the luminous intensity can be preset according to experience. In general, since the size of the corresponding portion to be detected is basically determined after the form information of the wearing structure is determined, the light emission intensity of the light emitter corresponding to the form information can be selected.
In the embodiment of the application, the larger the opening angle of the clamping part, the larger the elastic deformation amount of the elastic sleeve, or the longer the binding length of the binding belt, the larger the thickness or the size of the part to be detected is, so that the corresponding luminous intensity is generally larger.
Step S230: and controlling the light emitter to emit light signals with the light emitting intensity so as to determine blood oxygen information of the detected object.
According to the scheme provided by the embodiment of the application, the luminous intensity of the luminous device can be automatically determined according to the form information of the wearing structure, a detector is not required to manually set the luminous intensity of the luminous device, and the setting process is convenient and quick.
In one embodiment, step S220 may be implemented as follows:
Determining a light-emitting intensity range corresponding to the morphological information;
and determining the luminous intensity corresponding to the morphological information from the luminous intensity range.
Specifically, the light emission intensity range corresponding to the form information detected by the detector may be determined based on a correspondence relation between the preset form information and the light emission intensity range.
For example, the obtained form information is that the opening angle of the clamping member is 5 degrees, the light emission intensity range corresponding to 5 degrees is determined to be 1 candela to 4 candela from the corresponding relation between the preset form information and the light emission intensity range, and the light signal of any intensity can be determined to be the light emission intensity corresponding to the form information from the light emission intensity range of 1 candela to 4 candela.
According to the embodiment, the approximate luminous intensity range corresponding to the part to be detected can be determined according to the morphological information of the wearing structure, and the luminous intensity corresponding to the morphological information is determined from the range, so that the luminous intensity corresponding to the morphological information can be determined more quickly, and the blood oxygen detection efficiency is improved.
Optionally, the blood oxygen detection device in the embodiment of the present application may further include: analog-to-digital converter 120, the input of analog-to-digital converter 120 is electrically connected to receiver 140, the output of analog-to-digital converter 120 is electrically connected to controller 110, or the output of analog-to-digital converter 120 may be electrically connected to other control devices. The analog-to-digital converter 120 is configured to convert the electrical signal generated by the receiver 140 into a digital signal, and transmit the digital signal to the controller 110 or other control device, so that the controller 110 or other control device can determine blood oxygen information according to the data signal.
In one embodiment, as shown in fig. 5, the above method may further include the following steps S240 to S260.
Step S240: the electrical signal generated by the receiver conversion is acquired.
The receiver can send the electric signals generated by conversion to the controller in real time, and the controller can acquire the electric signals generated by conversion of the receiver in real time.
In the embodiment of the application, the controller can directly acquire the electric signals generated by the conversion of the receiver, and can also acquire the signals generated by the conversion of the receiver and processed by other devices. For example, the signal generated by the receiver conversion may be amplified by a signal amplifier, and the controller may receive the optical signal amplified by the signal amplifier.
Step S250: when the intensity of the acquired electric signal is not in the preset range, the intensity of the optical signal emitted by the light emitter is adjusted, so that the intensity of the electric signal generated by conversion of the acquired receiver is in the preset range.
In the embodiment of the present application, the preset range may be an intensity range of the convertible signal of the analog-to-digital converter, and the preset range may also be a range smaller than the intensity range of the convertible signal of the analog-to-digital converter.
For example, the intensity of the convertible signal of the analog-to-digital converter is in a range of 1 volt to 5 volts, the preset range may be 1 volt to 5 volts, and if the intensity of the acquired electric signal is 0.6 volt, the intensity of the acquired electric signal is determined to be not in the preset range if the intensity of the acquired electric signal is not in the range of 1 volt to 5 volts; if the intensity of the acquired electric signal is 2 volts and the intensity of the 2 volts is within the range of 1 volt to 5 volts, the intensity of the acquired electric signal is determined to be within the preset range.
For another example, the intensity of the convertible signal of the analog-to-digital converter may range from 1 volt to 5 volts, and the preset range may be from 2 volts to 4 volts or from 2.5 volts to 3.5 volts. It can be understood that, for the analog-to-digital converter, the closer the intensity of the signal to be converted is to the middle value of the intensity range of the convertible signal of the analog-to-digital converter, the better the conversion effect of the analog-to-digital converter is, the closer the intensity of the signal to be converted is to the upper/lower limit of the intensity range of the convertible signal of the analog-to-digital converter, and the poorer the conversion effect of the analog-to-digital converter may be, so the embodiment takes the intensity range of the convertible signal smaller than that of the analog-to-digital converter as the preset range, and can enable the intensity of the electric signal converted by the receiver acquired by the analog-to-digital converter to be converted more accurately, and the higher the conversion accuracy is achieved, thereby the accuracy of blood oxygen detection is higher.
In the embodiment of the application, the controller can acquire the electric signal generated by the conversion of the receiver in real time, monitor whether the intensity of the electric signal generated by the conversion of the receiver is in a preset range, and stop adjusting the intensity of the optical signal emitted by the light emitter when the intensity of the electric signal generated by the conversion of the receiver is monitored to be in the preset range.
In one embodiment, the controller may adjust the intensity of the light signal emitted from the light emitter according to a difference between the intensity of the acquired electrical signal generated by the receiver conversion and a limit value of the preset range. Specifically, when the intensity of the electric signal generated by the acquired receiver conversion is smaller than the lower limit of the preset range, the intensity of the optical signal emitted by the light emitter is increased, and when the intensity of the electric signal generated by the acquired receiver conversion is larger than the upper limit of the preset range, the intensity of the optical signal emitted by the light emitter is reduced. The present embodiment enables the controller to perform adjustment of the light emission intensity of the light emitter with reference, and has high adjustment speed and efficiency. Or the controller may also perform random adjustment or adjust the intensity of the light signal emitted by the light emitter by gradually increasing to a certain threshold value and then decreasing, and the embodiment of the application is not particularly limited.
In one embodiment, in step S250, the intensity of the light signal emitted by the light emitter may be adjusted as follows: the intensity of the light signal emitted by the light emitter is adjusted within a light emission intensity range corresponding to the form information detected by the detector. For example, if the emission intensity range corresponding to the form information detected by the detector is 1 candela to 4 candela, the intensity of the light signal emitted from the light emitter can be adjusted within the range of 1 candela to 4 candela. The present embodiment can adjust the intensity of the light signal emitted from the light emitter within the light emission intensity range, thereby enabling more purposeful intensity adjustment and faster adjustment speed.
Optionally, in adjusting the intensity of the optical signal emitted by the light emitter within the light emitting intensity range corresponding to the form information detected by the detector, if the intensity of the electrical signal generated by the acquired receiver conversion cannot be within the preset range, the intensity of the optical signal emitted by the light emitter may be adjusted outside the light emitting intensity range corresponding to the form information detected by the detector.
Step S260: the light emitter is controlled to emit an optical signal of the adjusted intensity.
In this embodiment, when the controller of the blood oxygen detection device acquires the electrical signal generated by the receiver conversion, and the controller determines that the intensity of the acquired electrical signal is not within the preset range, it indicates that the analog-to-digital converter cannot perform analog-to-digital conversion on the electrical signal, that is, cannot determine blood oxygen information of the user, at this time, the controller adjusts the intensity of the optical signal emitted by the light emitter, so that the controller controls the light emitter to emit the optical signal with the adjusted intensity, and thus, after the receiver receives and converts the optical signal with the adjusted intensity emitted by the light emitter, the analog-to-digital converter can perform analog-to-digital conversion on the electrical signal generated by the receiver conversion, thereby determining blood oxygen information of the user and completing blood oxygen detection. Therefore, the controller can further adjust the luminous intensity of the illuminator, so that the accuracy of blood oxygen detection is further improved.
In one embodiment, as shown in fig. 1, the receiver 140 and the controller 110 may be communicatively connected through a signal amplifier 150, where the signal amplifier 150 is configured to amplify the electrical signal generated by the receiver 140. Alternatively, the analog-to-digital converter 120 may be used to convert the electrical signal amplified by the signal amplifier 150 into a digital signal.
Specifically, as shown in fig. 1, an input of the signal amplifier 150 may be communicatively coupled to the receiver 140, an output of the signal amplifier 150 may be communicatively coupled to the analog-to-digital converter 120, and the controller 110 may be communicatively coupled to the signal amplifier 150.
The optical signal emitted by the light emitter and received by the receiver is sometimes weak, so that the electric signal generated by the receiver is also weak, the controller cannot send the electric signal with weak intensity to the analog-to-digital converter according to the electric signal generated by the receiver, and the analog-to-digital converter cannot normally perform analog-to-digital conversion.
In one embodiment, before step S240, the method may further include:
determining a magnification corresponding to the morphological information;
And amplifying the amplification factor by the electric signal generated by the receiver conversion.
Specifically, the controller may determine the magnification corresponding to the morphological information based on a preset correspondence between the morphological information and the magnification range.
In a specific embodiment, the controller may determine a magnification range corresponding to the above-described morphological information, from which a magnification corresponding to the morphological information is determined. For example, the form information detected by the detector is that the opening angle of the clamping component is 5 degrees, the magnification range corresponding to 5 degrees is found from the corresponding relation between the preset form information and the magnification range to be 1-5 times, and the magnification corresponding to the form information can be determined from the range of 1-5 times. According to the embodiment, the amplification factor range corresponding to the morphological information of the wearing structure is determined based on the corresponding relation between the preset morphological information and the amplification factor, the amplification factor corresponding to the morphological information is determined from the amplification factor range, and the approximate amplification factor range corresponding to the part to be detected can be determined according to the morphological information of the wearing structure, so that the amplification factor can be determined more quickly, parameters of blood oxygen detection equipment can be adjusted to meet the requirement of the part to be detected more quickly, and the blood oxygen detection efficiency is improved.
It can be understood that when the wearing structure is worn at different positions to be detected, the wearing structure has different shapes, and in this embodiment, the corresponding relationship between the preset shape information and the amplification factor can be preset according to experience. In general, after the morphological information of the wearing structure is determined, the size of the corresponding portion to be detected is also basically determined, and therefore, the magnification corresponding to the morphological information can be selected.
According to the embodiment, the intensity of the optical signal emitted by the light emitter and the amplification factor are set according to the form information of the wearing structure, so that parameters of the blood oxygen detection device can be set more flexibly, the intensity of the amplified electric signal can more easily meet the preset range, and the blood oxygen detection device can detect more efficiently.
In one embodiment, step S250 may be implemented as follows: and adjusting the intensity of the optical signal emitted by the light emitter, and adjusting the amplification factor of the electric signal generated by the conversion of the receiver, so that the intensity of the electric signal generated by the conversion of the acquired receiver is within the preset range. According to the embodiment, the intensity of the optical signal emitted by the light emitter and the amplification factor are adjusted according to the form information of the wearing structure, so that the parameters of the blood oxygen detection device can be flexibly adjusted, the intensity of the amplified electric signal can more easily meet the preset range, the parameters of the blood oxygen detection device can be adjusted more efficiently, and the blood oxygen detection device can detect more efficiently.
In one embodiment, the amplification of the electrical signal generated by the receiver conversion may be adjusted as follows: and adjusting the amplification factor of the electric signal generated by conversion of the receiver within the amplification factor range.
