For example, in an embodiment, the above five pulse thresholds may be set to 0, taking the case 1 as an example, if the central control module 152 receives the pulse electrical signals output by the first pulse sensor 1301, the second pulse sensor 1302, the third pulse sensor 1303, and the fourth pulse sensor 1304 after the preprocessing, and the central control module 152 does not receive the pulse electrical signal output by the fifth pulse sensor 1305 after the preprocessing, it indicates that the wearing position of the user is lower, the central control module 152 outputs wearing position adjustment prompting information according to the determined wearing position of the user, the user may move the pulse monitoring device upward according to the wearing position adjustment prompting information output by the central control module 152, and the rest of the above is repeated, that is, in this embodiment, whether the central control module 152 receives the first pulse sensor 1301, the second pulse sensor 1302, the third pulse sensor 1303, and the fourth pulse sensor 1304 is received by the central control module 152, and the central control module 152 does not receive the pulse electrical signals output by the fifth pulse, The pulse electrical signals output by the second pulse sensor 1302, the third pulse sensor 1303, the fourth pulse sensor 1304 and the fifth pulse sensor 1305 are used to adjust the wearing position of the pulse monitoring device of the present invention.

In summary of the above 5 situations, the pulse monitoring device of the present invention accurately positions the first pulse sensor, the second pulse sensor, and the third pulse sensor at the positions of the cunkou venation, the guan venation, and the midsized venation according to the comparison results of the pulse electrical signals received by the central control module and output by the first pulse sensor, the second pulse sensor, the third pulse sensor, the fourth pulse sensor, and the fifth pulse sensor after being preprocessed, and the comparison results of the first pulse threshold value, the second pulse threshold value, the third pulse threshold value, the fourth pulse threshold value, and the fifth pulse threshold value corresponding to the pulse electrical signals.

In order to more accurately wear the first pulse sensor 1301, the second pulse sensor 1302, and the third pulse sensor 1303 on the positions of the veins corresponding to the cunkou vein, the guan-shang vein, and the chi-shang vein, in the above 5 cases, after the user primarily adjusts the wearing position according to the wearing position adjustment prompt information, the wearing position needs to be finely adjusted.

The fine tuning process specifically comprises the following steps: after the central control module 152 receives the pulse electrical signals output by the first pulse sensor 1301, the second pulse sensor 1302 and the third pulse sensor 1303 after being preprocessed, at this time, the central control module 152 compares the pulse electrical signals output by the first pulse sensor 1301 and the second pulse sensor 1302 after being preprocessed with the pulse electrical signals output by the second pulse sensor 1302 and the third pulse sensor 1303. If the characteristics of the pulse electrical signals output by the first pulse sensor 1301 and the second pulse sensor 1302 after the preprocessing are the same, and the characteristics of the pulse electrical signals output by the second pulse sensor 1302 and the third pulse sensor 1303 are different, it indicates that the wearing position of the current user is slightly right, and the user can slightly adjust the pulse monitoring device to the left according to the trimming-related wearing position adjustment prompt information output by the central control module 152; if the characteristics of the pulse electrical signals output by the first pulse sensor 1301 and the second pulse sensor 1302 after the preprocessing are different, and the characteristics of the pulse electrical signals output by the second pulse sensor 1302 and the third pulse sensor 1303 are the same, it indicates that the wearing position of the current user is slightly left, and the user can slightly adjust the pulse monitoring device to the right according to the trimming wearing position adjustment prompt information output by the central control module 152. That is to say, the pulse monitoring device of the present invention compares the characteristics of the preprocessed pulse electrical signals output by the first pulse sensor and the second pulse sensor and the preprocessed pulse electrical signals output by the second pulse sensor and the third pulse sensor through the central control module, and adjusts the wearing position of the current user according to the result of the comparison.

For the above feature comparison, the feature comparison method in the prior art can be adopted, and is not limited herein, and can be selected by those skilled in the art as required. Taking the comparison of the characteristics of the pulse electrical signals output by the first pulse sensor 1301 and the second pulse sensor 1302 after the preprocessing as an example, N time points T1 and T2 … … TN (i.e. preset time points) can be preset first, then, the amplitudes of the pulse electrical signals output by the first pulse sensor 1301 and the second pulse sensor 1302 after the preprocessing at the N time points are respectively extracted, finally, the amplitudes of the pulse electrical signals output by the first pulse sensor 1301 after the preprocessing at the N time points are correspondingly compared with the amplitudes of the pulse electrical signals output by the second pulse sensor 1302 after the preprocessing at the N time points one by one, if the comparison result is greater than or equal to the preset condition threshold value, the characteristics of the pulse electrical signals output by the first pulse sensor 1301 and the second pulse sensor 1302 after the preprocessing are determined to be the same; if the comparison result is smaller than the preset condition threshold, it is determined that the characteristics of the pulse electrical signals output by the first pulse sensor 1301 and the second pulse sensor 1302 after the preprocessing are different. The preset condition threshold value refers to the number of the same amplitude values after feature comparison. If the preset condition threshold is 8, if the amplitude values at 9 time points are found to be the same after feature comparison, the comparison result meets the preset condition threshold, and the features of the pulse electrical signals output by the first pulse sensor 1301 and the second pulse sensor 1302 which are subjected to preprocessing are determined to be the same; if the amplitude values at only 4 time points are the same after the feature comparison, it indicates that the comparison result does not satisfy the preset condition threshold, and it is determined that the features of the pulse electrical signals output by the first pulse sensor 1301 and the second pulse sensor 1302 after the preprocessing are different. It should be understood that the preset condition threshold can be set by one skilled in the art according to the requirement, and is not limited herein.

If the user uses a pulse monitoring device comprising five pulse sensors, after the user finishes fine adjustment of the wearing position, the central control module 152 receives and records the pulse electric signals output by the first pulse sensor 1301, the second pulse sensor 1302 and the third pulse sensor 1303 which are preprocessed in real time, analyzes and calculates the pulse parameters of three veins of the user according to the three pulse electric signals to obtain the physiological information of the user, judges whether the pulse parameters of the three veins of the user obtained by analysis and calculation meet a preset pulse parameter threshold value or not, and outputs an alarm control electric signal according to the judgment result; if the user uses a pulse monitoring device including five pulse sensors and one body motion sensor, after the user finishes fine adjustment of the wearing position, the central control module 152 not only receives the pulse electrical signals output by the first pulse sensor 1301, the second pulse sensor 1302 and the third pulse sensor 1303 which are preprocessed, but also receives the body motion electrical signals output by the body motion sensor which is preprocessed, and simultaneously analyzes and calculates the pulse parameters of the three veins of the user according to the three pulse electrical signals and the body motion electrical signals to obtain the physiological information of the user, and judges whether the pulse parameters of the three veins of the user obtained by analysis and calculation meet the preset pulse parameter threshold value, and outputs an alarm control electrical signal according to the judgment result, specifically, the central control module 152 extracts the body motion characteristic amplitude (such as peak value) from the body motion electrical signals output by the signal preprocessing module, the extracted body motion characteristic amplitudes are used for respectively carrying out waveform fitting processing on pulse electric signals output by the first pulse sensor 1301, the second pulse sensor 1302 and the third pulse sensor 1303 which are subjected to preprocessing, the interference of the hand motion of the user on the pulse electric signals of the three venation is removed, and then the pulse parameters of the user are analyzed and calculated according to the pulse electric signals with the interference removed.

Taking the example of monitoring the pulsation of the left-hand wrist cunkou venation of the user, the venation corresponding to the heart of the human body, that is, the frequency and/or intensity of the pulsation of the venation can directly reflect the frequency and/or intensity of the pulsation of the heart of the human body, if the preset pulse amplitude threshold value of the venation is 100mV, the preset pulse frequency threshold value of the venation is 1.5Hz, and the preset time threshold value is 60s, the central control module 152 will find out the amplitude of which the amplitude is greater than or equal to 100mV, analyze and calculate the number of times of occurrence of the venation in 60s, then analyze and calculate the pulse frequency of the venation, if the calculated pulse frequency is greater than or equal to 1.5Hz, the heart is pulsating too fast, and the central control module 152 outputs an alarm control electrical signal to the alarm; if the calculated pulse frequency is less than 1.5Hz, it indicates that the heart is beating normally, and the central control module 152 will not send out the alarm control electric signal. The monitoring mode of the pulsation of other veins is similar to that of the vein of cunkou, and is not repeated here. In addition, it should be understood that the preset pulse parameter threshold may be set by the interactive function module according to the type of the user, and is not limited herein.

Under the condition that the pulse monitoring device is provided with the wireless transceiving module, the central control module can also send the physiological information (such as the pulse beating frequency, the pulse beating amplitude and the like of the user) of the user to the terminal equipment and/or the equipment such as a large database service platform and the like through the wireless transceiving module.

Preferably, the material of the packaging layer is a silicon-hydrogen ratio of 1: 1.5, the PDMS encapsulation layer can better enable the pulse sensor and the body motion sensor to be attached to the surface of the skin, and the sensitivity of the pulse sensor and the body motion sensor is improved. In addition, in order to increase the sensitivity and accuracy of the pulse sensor for sensing the pulse and the sensitivity and accuracy of the body motion sensor for sensing the body motion, a raised structure may be further disposed on the outer surface and/or the inner surface of the packaging layer of the pulse sensor and the body motion sensor, and/or a skin texture stripe may be further disposed on the outer surface of the packaging layer of the pulse sensor and the body motion sensor, wherein the skin texture stripe is a stripe similar to the skin texture. Specifically, the pulse sensor and the body motion sensor can be squeezed by the arranged convex structure when the veins beat, so that the pulse sensor and the body motion sensor can better monitor the pulsation of the veins; the arrangement of the skin texture-shaped stripes can increase the fitting degree of the pulse sensor and the body motion sensor to the surface of the skin, so that the pulsation of the venation can be better monitored. Of course, if the pulse sensor and the body motion sensor are provided inside the wrist band, a protrusion structure may be further provided on the outer surface and/or the inner surface of the wrist band, and/or a skin texture stripe may be further provided on the surface of the wrist band contacting the wrist of the user.

Alternatively, in the above embodiments, the shapes of the pulse sensor and the body motion sensor may be rectangular, circular, or square, and those skilled in the art can select the shapes as needed, which is not limited herein. The pulse sensor and the body motion sensor are preferably rectangular, and the length x width of the pulse sensor and the body motion sensor can be selected to be 15mm x 6.0mm or 15mm x 7.4 mm. The distance between adjacent pulse sensors or between adjacent body motion sensors is 0.5 mm-5 mm, and the preferable distance is 1.0 mm. The lead for leading out the electrode of the pulse sensor and the lead for leading out the electrode of the body motion sensor are preferably arranged in a snake shape (namely in a bent S-shaped arrangement), and the arrangement mode can increase the stretching strength of the leads during stretching and prolong the service life of the leads.
