Fig. 1 shows a method for determining a pulse waveform map, which is applied to a computer device and includes step S101, step S102, and step S103. In step S101, obtaining an analog signal related to a pulse of a user, wherein the analog signal is acquired by a corresponding pressure resistance type pressure sensing device; in step S102, determining a target enhancement parameter of the signal conditioning device according to the analog signal; in step S103, the signal conditioning device is adjusted based on the target enhancement parameter, and the signal conditioning device performs signal enhancement on the analog signal and determines a corresponding pulse waveform diagram. For example, the computer device includes, but is not limited to, a user device, a network device, or an integrated device of the user device and the network device, and the like, wherein the user device includes, but is not limited to, any mobile electronic product capable of human-computer interaction with a user (e.g., human-computer interaction through a touch panel), such as a smart phone, a tablet computer, a pulse meter, and the like; network devices include, but are not limited to, computers, network hosts, a single network server, multiple sets of network servers, or a cloud of multiple servers.
Specifically, in step S101, an analog signal related to the pulse of the user is acquired, wherein the analog signal is acquired by the corresponding piezoresistive pressure sensing device. For example, the computer device may include or have established a communication connection with a piezoresistive pressure sensing device. The piezoresistive pressure sensor is formed by using the piezoresistive effect of monocrystalline silicon, a monocrystalline silicon wafer is used as an elastic element, a group of equivalent resistors are diffused in the specific direction of the monocrystalline silicon on the monocrystalline silicon wafer by using the process of an integrated circuit, the resistors are connected into a bridge circuit, and the monocrystalline silicon wafer is arranged in a cavity of the sensor. When the pressure changes, the monocrystalline silicon generates strain, so that the strain resistance directly diffused on the monocrystalline silicon generates change in direct proportion to the measured pressure, and then a bridge circuit obtains a corresponding voltage output signal. The piezoresistive pressure sensing device is arranged at the pulse of a user, and collects analog signals related to the pulse of the user, and the computer equipment can receive the corresponding analog signals and the like through the piezoresistive pressure sensing device or a communication connection with the piezoresistive pressure sensing device. For example, the corresponding analog signal may be stored on another device, and the computer device may receive the analog signal transmitted by the computer device via a communication link with the other device. In some cases, to ensure a valid pulse period of the voltage output signal, the signal output duration of the analog signal is greater than or equal to a predetermined signal output duration, such as 2 seconds or 2.5 seconds. Further, the analog signals comprise voltage output signals which are acquired in real time and are related to the pulse of the user, corresponding enhancement parameters are determined through the analog signals acquired in the initial stage, and therefore the signal conditioning device is adjusted through the enhancement parameters, so that the analog signals acquired in the subsequent stage are enhanced, and a pulse waveform diagram corresponding to the digital signals is output.
As shown in fig. 2, the waveform diagram in the left graph a is the waveform obtained by the floating-middle-deep three-part pulse diagnosis method, the waveform diagram in the right graph b is the ideal waveform diagram that we want to obtain, and the pulse waves with different amplitudes in the left graph can be uniformly formed into the more consistent pulse waveform shown in the right graph after special processing. If a high-precision analog-to-digital conversion circuit is used for amplification, the actually obtained data quality is not high, and the actual waveform has obvious distortion compared with an ideal waveform; the accuracy of the single analog-to-digital conversion circuit is difficult to achieve, and a signal conditioning device must be added.
In step S102, a target enhancement parameter of the signal conditioning device is determined from the analog signal. For example, the signal conditioning device protects and enhances the analog information output by the sensing device, and enhances the analog signal with smaller amplitude to the analog signal with proper amplitude, better quality and less distortion shown in fig. 2 b. In some cases, the signal conditioning device can also filter and reduce noise of analog signals. The target enhancement parameter includes a parameter for signal enhancement of the analog signal in the signal conditioning apparatus, which is used to indicate a magnification ratio for enhancing the analog signal, and the like. By comparing the analog signal with a preset signal amplitude or voltage difference value, etc., the multiplying power of the analog signal with the preset signal amplitude or voltage difference value can be determined, and the multiplying power is determined as a corresponding target enhancement parameter, etc.
In step S103, the signal conditioning device is adjusted based on the target enhancement parameter, and the signal conditioning device performs signal enhancement on the analog signal and determines a corresponding pulse waveform diagram. For example, after the computer device determines the corresponding target enhancement parameter, the corresponding signal conditioning device is adjusted based on the target enhancement parameter, and then the analog signal is processed by the adjusted signal conditioning device to output the pulse oscillogram of the digital signal. The computer device can present the pulse waveform diagram through a display device, or transmit the pulse waveform diagram to other devices for presentation, and the like.
In some embodiments, the step S102 includes a sub-step S1021 (not shown) and a sub-step S1022 (not shown), in which step S1021, the analog signal is input to the signal conditioning device for signal enhancement, thereby determining a corresponding initial pulse waveform map; in step S1022, a target enhancement parameter of the signal conditioning device is determined according to the initial pulse waveform map. For example, after the computer device obtains the corresponding analog signal, the analog signal may be converted into an electronic signal, a corresponding initial pulse waveform diagram is determined, and then the target enhancement parameter is determined according to the initial pulse waveform diagram, the preset amplitude threshold value, and the like, for example, the multiplying power of the initial pulse waveform diagram and the preset amplitude threshold value is calculated according to the amplitude of the pulse waveform diagram, and the multiplying power is determined as the corresponding target enhancement parameter, and the like. In some embodiments, the signal conditioning device comprises a signal enhancement unit and an analog-to-digital conversion unit; in step S1021, inputting the analog signal into the signal enhancement unit to perform signal enhancement on the analog signal to determine a corresponding initial enhanced signal; and converting the initial enhanced signal into a corresponding initial pulse waveform diagram through the analog-to-digital conversion unit. For example, the signal enhancement means is used to perform signal enhancement on an analog signal, for example, to amplify the analog signal to a rated level, perform sound quality control, remove noise, and the like. The analog-to-digital conversion unit includes an electronic component for converting an analog signal into a digital signal, for example, an input voltage signal is converted into an output digital signal, such as an a/D converter. The basic principle is to sample the input analog signal at regular time intervals and compare it with a series of standard digital signals, which converge successively until the two signals are equal. The binary number representing the signal is then displayed, and a wide variety of analog-to-digital converters exist, such as direct, indirect, high speed, high precision, ultra high speed, etc. Here, the analog-to-digital conversion unit (e.g. analog-to-digital converter) generally adopts a 16-bit analog-to-digital converter according to the design requirement, and the sampling rate is above 200 Hz. The analog signal is usually a weak electrical signal, the computer device first performs signal enhancement on the analog signal through the signal enhancement unit, and then inputs the analog signal after signal enhancement into the analog-to-digital conversion unit, and converts the analog signal into a corresponding initial pulse waveform diagram for subsequent calculation of target enhancement parameters.
In some embodiments, the signal enhancement unit comprises a pre-enhancer unit for fixed-rate signal enhancement of the analog signal and a programmable enhancer unit for adjustable-rate signal enhancement of the analog signal; wherein, the inputting the analog signal into the signal enhancement unit to perform signal enhancement on the analog signal to determine a corresponding initial enhanced signal includes: inputting the analog signal into the pre-enhancer unit, and performing signal enhancement with fixed multiplying power on the analog signal so as to determine a first analog signal; inputting the first analog signal into the programmable enhancer unit to determine a corresponding initial enhancement signal, wherein the adjustable magnification for the programmable enhancer unit comprises a base magnification. For example, the signal enhancement unit includes a corresponding pre-enhancer unit and a programmable enhancer unit, wherein the pre-enhancer unit includes a circuit or an electronic device disposed between the signal source and the amplifier stage, and is designed for receiving a weak voltage signal from the signal source, such as a preamplifier, which is mainly designed with a differential amplification circuit, can be built with discrete components, and can also be used as a preamplifier with an instrumentation amplifier; wherein the amplification rate of the pre-enhancer unit is related to the voltage properties or voltage range of the sensor, such as in some embodiments, the fixed rate is related to the supply voltage range of the piezoresistive pressure sensing device. For example, the pre-enhancer unit is used to enhance the signal of the analog information with a fixed magnification, the fixed magnification is related to the power supply voltage range of the piezoresistive pressure sensing device, specifically, for example, the voltage range is (+5v) - (0v), and the like, and the corresponding fixed magnification is 20-50 times; the voltage range is (+5v) - (-5v), and the corresponding fixed multiplying power is 15-30 times; the voltage range is (3-3.3v) - (0v), and the corresponding fixed multiplying power is 50-100 and the like; and if the sensing device is supplied with power by using a constant current, calculating and determining the internal resistance of the sensing device according to the power supply voltage range of the sensing device.
The programmable enhancer unit is used for adjusting adjustable parameters in the process of signal enhancement of the analog signal, and the adjustable parameters comprise adjustable multiplying power related to the analog signal. In some embodiments, the corresponding target enhancement parameter consists of both a fixed magnification and an adjustable magnification, as the corresponding target enhancement parameter is used to indicate the product of the fixed magnification and the adjustable magnification. In some embodiments, the target enhancement parameter is only used to indicate an adjustable magnification, which facilitates quick adjustment of the signal enhancement device, for example, after the computer device obtains the corresponding target enhancement parameter, the target enhancement parameter is directly sent to the programmable enhancement unit, so as to adjust the programmable enhancement unit, thereby achieving adjustment of the signal enhancement magnification. Here, in the process of determining the target enhancement parameter, in order to prevent the influence of the adjustable magnification on the calculation process, the computer device sets the adjustable magnification to an initial magnification (e.g., 1-fold, etc.) so that the programmable enhancer unit does not have signal enhancement, etc., for the analog signal.
As shown in fig. 3, the signal conditioning apparatus 2000 includes a signal enhancement unit 2002 and an analog-to-digital conversion unit 2001, and further includes a corresponding filtering unit 2003 and a comment offset unit 2004, where the specific connection relationship is shown in the figure. In some embodiments, the signal conditioning device further comprises a filtering unit; wherein, the step S102 further includes a step S1023 (not shown), in which the first analog signal is input into the filtering unit to be preprocessed, so as to determine a corresponding second analog signal; wherein, in step S1022, the second analog signal is input into the programmable enhancer unit, so as to determine a corresponding initial enhancement signal, wherein the adjustable magnification corresponding to the programmable enhancer unit includes a basic magnification. For example, the filtering unit includes a device for performing filtering and noise reduction processing on analog information, such as a low-pass filtering device, and the like, and the rule is that low-frequency signals can normally pass through, and high-frequency signals exceeding a set critical value are blocked and attenuated. The low pass filter is designed as a second order low pass filter, and the-3 dB cut-off frequency is set within the range of 200Hz-300 Hz. The low pass filter is used to improve the signal quality of the analog signal. The filter unit is disposed between the pre-enhancer unit and the programmable enhancer unit. The first analog signal refers to an unprocessed analog signal which is subjected to signal enhancement only by the preposed enhancer unit, and the second analog signal refers to an analog signal to be enhanced which is subjected to filtering processing and is subjected to secondary signal enhancement by the programmable enhancer unit. In some embodiments, the signal conditioning device further comprises a level shifting unit; wherein the method further comprises a step S104 (not shown), in step S104, determining a corresponding potential difference value according to the lowest value of the initial pulse waveform diagram and the lowest input level of the analog-to-digital conversion unit; adjusting the level shift unit according to the potential difference value, thereby determining an adjusted pulse waveform diagram; in step S1022, a target enhancement parameter of the information adjusting apparatus is determined according to the adjusted pulse waveform diagram. For example, the level cheap unit is used for adjusting the level value of the analog signal, and particularly, the level offset unit is used for providing a reference level for the pre-emphasis unit, and can be composed of an 8BIT-10BIT digital-to-analog converter and a follower amplifier, and can also be directly output to the pre-emphasis device by the digital-to-analog converter. The computer device determines a corresponding potential difference value according to the lowest value of the initial pulse waveform diagram and the lowest input level of the analog-to-digital conversion unit, for example, according to the lowest value of the amplitude range in the analog-to-digital conversion unit as the lowest input level, and determines the corresponding potential difference value by subtracting the lowest input level from the lowest value of the initial pulse waveform diagram. In order to ensure that the enhanced waveform of the initial pulse waveform is in an ideal position, the level shift unit is adjusted by the potential difference value, the adjusted pulse waveform is ensured to be closer to the lowest level, and the like, wherein the level shift unit is in point connection with the prepositive enhancement unit. In some embodiments, said adjusting said level shift unit according to said potential difference value to determine an adjusted pulse waveform profile comprises: and determining corresponding adjustment potential information according to the potential difference value and a preset potential threshold value, and adjusting the level offset unit based on the adjustment potential information to enable the lowest value of the adjusted pulse oscillogram of the initial pulse oscillogram and the adjustment potential difference value of the lowest input level to be less than or equal to the preset potential threshold value. For example, since the enhancement multiple of the initial pulse waveform diagram is small, the lowest value of the corresponding initial pulse waveform diagram is always within the amplitude range of the analog-to-digital conversion device, and the initial pulse waveform diagram is moved according to the potential difference value, so that the lowest value of the adjusted waveform diagram is close to the lowest input level, and if the adjustment potential difference value between the lowest value of the adjusted waveform diagram and the lowest input level is less than or equal to the preset potential threshold, the lowest value of the adjusted waveform diagram is slightly higher than the lowest input level, and the like. Specifically, the corresponding potential difference value is calculated, the difference value between the potential difference value and the preset potential threshold value is solved, the difference value is used as the adjusting potential value of the level shift unit, the adjusting potential value is input into the corresponding level shift unit, and the level shift is performed on the initial pulse wave, so that the adjusting potential difference value between the lowest value of the adjusted pulse wave form diagram after the initial pulse wave form diagram is adjusted and the lowest input level is smaller than or equal to the preset potential threshold value. The preset potential threshold may be a specific value, or may be a range interval, and the corresponding adjusted potential difference value is less than or equal to the highest value or the lowest value of the range interval.
In some embodiments, in step S1022, the computer device determines a corresponding target enhancement parameter according to the amplitude of the initial pulse waveform map and a preset amplitude threshold, wherein the target enhancement parameter includes a corresponding adjustable magnification. For example, the corresponding target enhancement parameter is used to indicate the enhancement magnification of the programmable enhancer unit, the enhancement magnification of the programmable enhancer unit may be any magnification, or an integer magnification, or a magnification multiplied by an exponent with a base 2 (e.g., 1, 2, 4, 8 …, etc.), and the specific magnification device is not limited herein. The computer device reads data in the initial pulse waveform graph converted by the analog-to-digital converter within 2.5 seconds, calculates the amplitude of the initial pulse waveform graph, for example, by calculating the difference value between the lowest value and the highest value, compares the amplitude with a preset amplitude threshold value, determines a corresponding proportion, for example, divides the amplitude of the initial pulse waveform graph by the preset amplitude threshold value so as to determine a corresponding proportion, and determines the proportion as the adjustable multiplying power of the programmable enhancer unit, and the like.

For example, if the corresponding adjustable multiplying power includes an integral multiple of the adjusting multiplying power, determining a corresponding maximum adjusting multiplying power N by a regression method, for example, determining a series of positive integers M according to the amplitude of the initial pulse wave oscillogram in combination with a preset amplitude threshold value, so that the amplitude multiplied by M is less than or equal to the preset amplitude threshold value, and further taking the maximum multiplying power in M as the positive integer N to be solved; or, in some cases, if N is a multiple of an exponent with a base 2, the maximum multiple of M that meets the exponent with a base 2 is taken as the corresponding adjustable multiple N, and so on.

For example, the computer device determines a level shift parameter (e.g., a potential difference value) corresponding to the level shift unit, an adjustable magnification of the programmable enhancer unit, and the like, and then the computer device sends the corresponding level shift parameter (e.g., a shift potential value determined according to the potential difference value and a preset potential difference threshold value) to the level shift unit and sends the corresponding adjustable magnification to the programmable enhancer unit, so as to adjust the corresponding level shift unit and the programmable enhancer unit, and thus, after a subsequent analog signal passes through the adjusted signal conditioning device, a desired pulse waveform diagram can be formed.
