S304: and confirming whether the current state of the user is a motion state.
The server 105 confirms whether the current state of the user is a motion state. The server 105 may preset an action amplitude threshold and an action frequency threshold, and the server 105 compares the action amplitude and the action frequency with the action amplitude threshold and the action frequency threshold, respectively, to determine whether the current state of the user is a motion state. For example, if the server 105 determines that the motion amplitude is greater than the motion amplitude threshold and/or the motion frequency is greater than the motion frequency threshold, the server 105 confirms that the current state of the user is a motion state, and proceeds to step S305.
S305: it is further queried whether there is a second blood pressure curve of the history that the user is not in motion during the same time period.
The server 105 further queries whether there is a second blood pressure curve of the history that the user is not in the exercise state within the same time period, for example, at the time period 19-20, the user's state is in the exercise state, and then the server 105 queries whether there is a second blood pressure curve of the history that the user is not in the exercise state (for example, the user is in the sleep state) within the same time period (19-20). If the second blood pressure curve exists, the process proceeds to step S306.
S306: the first and second blood pressure curves are correlated.
The server 105 correlates the first blood pressure curve with the second blood pressure curve, i.e. the server 105 cuts a part of the curve in the same time period from the second blood pressure curve and correlates the cut part of the curve with the first blood pressure curve, so that the cut part of the curve can be displayed synchronously with the first blood pressure curve.
The server 105 forms a recommendation for the current course of motion from the difference between the blood pressure values characterized by the first blood pressure curve and the second blood pressure curve within the same time period. The server 105 presets a first difference threshold and a second difference threshold, where the second difference threshold is smaller than the first difference threshold. The server 105 further compares the difference with a first difference threshold, and if the server 105 determines that the difference is greater than the first difference threshold, the server 105 forms a recommendation to decrease the amount of motion during the current motion. If the server 105 determines that the difference is less than or equal to the first difference threshold, the server 105 compares the difference with a second difference threshold, and if the server 105 determines that the difference is less than the second difference threshold, the server 105 forms a suggestion for increasing the amount of motion in the current motion process.
Therefore, the server 105 of the embodiment forms a suggestion for the current exercise process according to the difference value between the blood pressure values represented by the first blood pressure curve and the second blood pressure curve in the same time period, so that the suggestion can be formed in real time, intellectualization is realized, and the body-building efficiency and the use experience of the user are improved.
The present application provides a blood pressure monitoring method according to another embodiment, as shown in fig. 4, the blood pressure monitoring method according to the present embodiment includes the following steps:

S402: and generating a first blood pressure curve which changes along with time according to the blood pressure detection data, and obtaining the states of the user at different time intervals according to the action detection data.
S403: the status is marked on the first blood pressure curve.
S404: and confirming whether the current state of the user is a motion state.
Steps S401-S404 are the same as steps S301-S304 and will not be described herein.
S405: querying whether there is a second blood pressure curve that is historical for which the user is not in motion for both the first time period and the second time period.
The server 105 confirms that the state of the user is the motion state, and the server 105 further inquires whether there is a second blood pressure curve which is recorded in history and is not in the motion state in the first time period and the second time period. The first time period is the time period when the user is in the motion state currently; the second time period is a time period after the user ends the current motion state. For example, if the first time period is 19 points-20 points and the second time period is 20 points-21 points, the server 105 queries the second blood pressure curve that has been recorded to have no user in motion for the time period of 19 points-21 points. If the server 105 inquires that the second blood pressure curve exists, the process proceeds to step S406.
S406: the first and second blood pressure curves are correlated.
Step S406 is the same as step S306, and is not described herein again.
S407: and forming a suggestion for the next exercise process according to the difference value between the blood pressure values represented by the first blood pressure curve and the second blood pressure curve in a preset time period after the user finishes the current exercise state.
The server 105 forms a recommendation for the next exercise session based on the difference between the blood pressure values represented by the first blood pressure curve and the second blood pressure curve within a predetermined time period after the user has finished exercising. Specifically, the server 105 further presets a difference threshold and a time threshold, and the server 105 compares the difference with the difference threshold; if the difference is smaller than the preset difference threshold or the difference is larger than the difference threshold, the server 105 counts the duration that the difference is smaller than the preset difference threshold or the difference is larger than the difference threshold, and compares the duration with the time threshold. If the server 105 determines that the difference is smaller than the preset difference threshold or the duration of the difference larger than the preset difference threshold is smaller than the preset time threshold, the server 105 forms a suggestion for increasing the amount of exercise in the next exercise process.
In this embodiment, the server 105 forms a suggestion for the next exercise process according to the difference between the blood pressure values represented by the first blood pressure curve and the second blood pressure curve within the predetermined time period after the user finishes the exercise state, so that a suggestion for the next exercise can be formed, the intellectualization is realized, and the use experience of the user is improved.
The present application provides a blood pressure monitoring method of another embodiment, which is used for monitoring an emotional state of a user, as shown in fig. 5, the blood pressure monitoring method specifically includes the following steps:
s501: and controlling the blood pressure detection device to detect blood pressure detection data and heart rate detection data of the user and receive the blood pressure detection data and the heart rate detection data.
The server 105 controls the blood pressure detection device 102 to detect the blood pressure detection data and the heart rate detection data of the user and receives the blood pressure detection data and the heart rate detection data; that is, the blood pressure detection device 102 is provided with a cuff, the blood pressure detection device 102 can detect blood pressure detection data and heart rate detection data of the user by the cuff, and the server 105 acquires the blood pressure detection data and the heart rate detection data of the user, which may be blood pressure, brain waves, blood oxygen saturation, or the like, from the blood pressure detection device 102 through the terminal 104.
S502: and generating a blood pressure curve which changes along with time according to the blood pressure detection data, and obtaining the emotional states of the user in different time periods according to the heart rate detection data.
The server 105 generates a blood pressure curve changing with time according to the blood pressure detection data, for example, the server 105 establishes a coordinate system, the time is used as an abscissa of the coordinate system, and the blood pressure detection data is used as an ordinate of the coordinate system; the server 105 generates a time-varying blood pressure curve on the coordinate system from the blood pressure detection data. Therefore, the server 105 can monitor the blood pressure detection data of the user in real time, and can remind the user when the blood pressure detection data is abnormal.
The emotional state may include an emotional abnormal state and a non-emotional abnormal state. When the emotional state is an emotional abnormal state, for example, the emotional abnormal state may include emotional agitation, the blood pressure of the user is increased, and moreover, the emotional abnormal state may cause the blood vessels of the user to shrink suddenly, the blood pressure is increased immediately, and cardiovascular and cerebrovascular diseases are easy to occur. Therefore, the server 105 obtains the emotional states of the user at different time intervals according to the heart rate detection data to monitor the current emotional state of the user, so as to remind the user to adjust the mood in time and avoid sudden rise of the blood pressure of the user.
The server 105 may determine the heart rate variation amplitude of the user within a preset time interval according to the heart rate detection data, and determine the current emotional state of the user according to the heart rate variation amplitude. Specifically, the server 105 is provided with preset time, and the preset time may be 10 minutes, so that the server 105 determines the heart rate variation amplitude of the user within 10 minutes interval according to the heart rate detection data, and determines the current emotional state of the user according to the heart rate variation amplitude; for example, the amplitude threshold is preset in the server 105, the server 105 compares the heart rate variation amplitude with the amplitude threshold, and if the heart rate variation amplitude is greater than the amplitude threshold, the server 105 determines that the current emotional state of the user is an emotional abnormal state, and reminds the user. If the heart rate variation amplitude is smaller than the amplitude threshold value, the server 105 judges that the current emotional state of the user is a non-emotional abnormal state.
S503: the emotional state is marked on the blood pressure curve.
The server 105 marks the emotional state on the blood pressure curve; for example, server 105 labels the emotional abnormal state and the non-emotional abnormal state on the blood pressure curve according to time. The server 105 may transmit the blood pressure curve marked with the emotional state to the terminal 104, and the user may visually observe the influence of the emotional state on the blood pressure detection data through the terminal 104.
The blood pressure monitoring method of this embodiment can be implemented on the basis of the blood pressure monitoring method disclosed above, for example, after step S501 and step S13, which are not described herein again.
The embodiment controls the blood pressure detection device 102 to detect the blood pressure detection data and the heart rate detection data of the user and receive the blood pressure detection data and the heart rate detection data; the method comprises the steps of generating a blood pressure curve which changes along with time according to blood pressure detection data, obtaining emotional states of a user in different time periods according to heart rate detection data, namely obtaining the emotional states of the user according to the heart rate detection data, marking the emotional states on the blood pressure curve, observing the influence of the emotional states on the blood pressure from the marked blood pressure curve, and improving the use experience of the user.
In an embodiment, the server 105 may obtain blood pressure detection data of a plurality of users, generate a labeled blood pressure curve for each user, and share the labeled blood pressure curve among the plurality of users, where the labeled blood pressure curve is the blood pressure curve disclosed in the above embodiment. When the user sets the sharing blood pressure curve through the terminal 104, the server 105 transmits the marked blood pressure curve to the terminals 104 of other users, so as to share the marked blood pressure curve among a plurality of users.
The blood pressure monitoring method disclosed in the above embodiments can be implemented on the terminal 104, and will not be described herein again. How the server 105 acquires the health information of the human body is described in detail below.
Since the human health information is often obtained by using rich empirical data and inference rules, the server 105 can acquire rich blood pressure detection data and has strong data processing capability, so that the server 105 can analyze the blood pressure detection data to acquire the human health information, and accuracy of blood pressure detection and data processing can be improved. In addition, the terminal 104 of the embodiment displays the health information and the blood pressure detection data, so that the user can know the health condition of the user in time, and the risk of diseases is reduced.
Specifically, the server 105 may pre-store blood pressure detection data, which may include a normal blood pressure detection data range, a plurality of blood pressure detection data of the same human body, a plurality of blood pressure detection data of human bodies, and the like. The server 105 may also pre-store other physiological data and mapping relationship between the other physiological data and the blood pressure detection data. The server 105 may analyze the blood pressure detection data forwarded by the terminal 104 according to the pre-stored blood pressure detection data to obtain the health information of the human body. For example, the server 105 may compare the blood pressure detection data of the human body a transferred by the terminal 104 with the normal blood pressure detection data range, or compare the blood pressure detection data of the human body a transferred by the terminal 104 with the past blood pressure detection data of the human body a, or compare the blood pressure detection data of the human body a transferred by the terminal 104 with the blood pressure detection data of the human body B, and obtain the health information of the human body a according to the comparison result.
The blood pressure detection data may include a pulse wave generated by the heart pulse pushing blood along the blood vessel, which is a periodic pressure wave. The pulse wave of a human body contains rich physiological information, such as blood pressure, heart rate, cardiovascular information and the like. Through the analysis of the pulse waveform, the cardiovascular health information can be acquired so as to reduce the occurrence of cardiovascular diseases.
Alternatively, in order to improve the accuracy of the health information, the server 105 needs to perform filtering processing on the plurality of pulse waves after acquiring the plurality of pulse waves from the terminal 104 to remove the interference noise.
Specifically, the server 105 acquires the amplitude of the pulse wave, and determines whether the amplitude is within a preset amplitude range; if yes, the server 105 determines the pulse wave with the amplitude within the preset range as the first pulse wave, and filters out the pulse waves except the first pulse wave. Further, the server 105 may obtain the amplitude of the feature point of the first pulse wave, which may include a reflected wave point, a peak point, a valley point, or other extreme point or inflection point of the first pulse wave.
Of course, in another embodiment, the server may further obtain a period of the pulse wave, and filter the pulse wave whose period is not within a preset period to obtain the first pulse wave, that is, the period is used as the filtering condition. Of course, in other embodiments, the amplitude and the period of the pulse wave can be used as the filtering condition.
Different human bodies or the same human body in different health states generate different pulse waves, i.e. different pulse conditions. The pulse conditions of traditional Chinese medicine are various, such as the smooth pulse, the pulse-promoting pulse, the chordal pulse, the Pingtai pulse, the superficial pulse, the deep pulse, the slow pulse, the rapid pulse, the deficient pulse, etc., and the waveforms of each pulse condition are different, as shown in fig. 6, the waveforms of the smooth pulse, the pulse-promoting pulse, the chordal pulse and the Pingtai pulse are all different.
Different pulse conditions represent different health conditions of the human body, and in order to improve the accuracy of the health information, the server 105 of the embodiment further performs pulse condition (waveform) recognition on the first pulse wave.
Specifically, the server 105 of the present embodiment stores preset waveforms, which at least include a smooth pulse waveform, a pulse promoting waveform, a chordal pulse waveform, a flat pulse waveform, or the like. The server 105 matches the first pulse wave with a preset waveform after filtering the plurality of pulse waves forwarded by the terminal 104; the server 105 further obtains a preset waveform matched with the first pulse wave as a first preset waveform, and obtains health information according to the first preset waveform. For example, if the server 105 determines that the first pulse wave forwarded by the terminal 104 matches a preset smooth pulse waveform, it determines that the first pulse wave is a smooth pulse; the server 105 may further transmit the first pulse wave or the first preset waveform and the health information "slippery pulse" back to the terminal 104.
Optionally, the server 105 obtains first feature information of the first pulse wave and second feature information of the preset waveform, respectively, and if a difference between the first feature information and the second feature information is smaller than a preset difference, the server 105 determines that the first pulse wave matches the preset waveform.
Specifically, the feature information of the present embodiment may include the waveform period and the waveform stagnation point (including the extreme point and the inflection point) information of the first pulse wave. The waveform stagnation point information includes information such as the number of waveform stagnation points and time intervals between adjacent waveform stagnation points.
As shown in fig. 6, the difference between the waveform period of the pulse-promoting waveform and the waveform periods of other pulse conditions is large, and if the server 105 determines that the difference between the waveform period of the first pulse wave and the preset waveform period of the pulse-promoting waveform is smaller than the preset difference, the first pulse wave can be determined as the pulse-promoting. If the server 105 determines that the difference is greater than the preset difference, it further determines whether the number of waveform extreme points of the third pulse wave is 2 (the number of waveform extreme points of the preset smooth pulse is 2), and determines whether the amplitude of the second waveform stagnation point is larger and lower than the first waveform stagnation point; if yes, the third pulse wave can be determined as the smooth pulse. If the server 105 determines that the number of the waveform extreme points of the third pulse wave is equal to 3, it may further determine whether the interval time between the first waveform stagnation point and the second waveform stagnation point of the third pulse wave is less than a preset time (the time interval between the first waveform stagnation point and the second waveform stagnation point of the preset chordal pulse); if yes, the first pulse wave can be judged as a string pulse.
The pulse condition (waveform) of the pulse wave can be identified through the waveform period and the waveform stagnation point information of the pulse wave. Of course, in other embodiments, the pulse condition (waveform) of the pulse wave can be identified according to other characteristic information of the pulse wave. Of course, the server 105 may filter the acquired waveform stagnation points before performing pulse recognition to reduce noise interference.
Pulse diagnosis is one of the four diagnostic methods in diagnostics of traditional Chinese medicine, and is a unique diagnostic method. It mainly uses the finger sense to analyze the pulse 'position, number, shape and potential' characteristics to judge the functional state of viscera, thus realizing the purpose of non-invasive diagnosis and having positive significance for the diagnosis and treatment of diseases.
Although the existing pulse condition instrument can achieve the process of feeling pulse and graphically display the pulse wave, so that a user can visually know the pulse condition through the pulse wave, health information is obtained from the pulse condition, and abundant clinical experience is needed, so that non-medical personnel or non-professional medical personnel are difficult to accurately obtain the health information from the pulse condition waveform.
To solve the above problem, the server 105 of this embodiment further analyzes the first pulse wave to obtain more specific human health information from the first pulse wave, and the health information of this embodiment includes information such as blood pressure, pulse strength, pulse rate, and reflected wave enhancement index (AI) reflecting elasticity of artery in addition to the pulse condition information.
Specifically, the server 105 obtains several pulse waves with the largest pulse wave amplitude in the whole measurement process, for example, 3 pulse waves, and obtains the pulse strength of the human body according to the average value of the amplitudes of the peak points. The larger the amplitude of the mean value is, the larger the pulse strength is, and the magnitude of the pulse strength represents the strength of the human physique; the server 105 may also obtain pulse rate, AI value, and the like from the first pulse wave.
The server 105 returns the acquired health information to the terminal 104, and the terminal 104 displays the health information, as shown in fig. 7 and 8.
Further, the server 105 stores a preset range, and determines whether the health information is in the preset range; if yes, controlling the health information display state on the terminal 104 to be normal; if not, the health information display state on the terminal 104 is abnormal.
The server 105 may also transmit the first pulse wave or the pulse waveform corresponding to the first pulse wave, the type of the first pulse wave, the blood pressure data, etc. back to the terminal 104, and the terminal 104 displays the pulse waveform, the type, and the blood pressure data.
Optionally, the server 105 of this embodiment further obtains health information of the elasticity of the blood vessel of the human body according to the reflected wave point and the peak point, for example, if the server 105 determines that the reflected wave point is on the right side of the peak point (as shown in fig. 7), the obtained health information is that the elasticity of the blood vessel is better; if the server 105 determines that the reflected wave point is on the left side of the peak point (as shown in fig. 8), the acquired health information is that the elasticity of the blood vessel is poor.
The server 105 can also acquire health information such as bradycardia or tachycardia and arrhythmia according to the heart rate data; the server 105 may also obtain arterial health information from the AI values. The terminal 104 may also display such health information.
Different from the prior art, the server 105 analyzes the blood pressure detection data to obtain the health information of the human body, so that the accuracy of blood pressure detection and data processing can be improved; in addition, the terminal 104 of the present embodiment can display detailed health information, not just pulse waves, so that the non-medical staff can clearly know the health status of the non-medical staff through the health information.
