Detailed Description

The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and those skilled in the art can obtain other embodiments without inventive effort based on the embodiments of the present invention, and all embodiments are within the protection scope of the present invention.

The concept source of the invention is that China is gradually advancing to an aging social level, more and more old people will enter the aging community in the future, and the requirements of the aging community in all aspects are invisibly improved.

At the age of 60 years or above, proper motion and entertainment can effectively adjust the mind and body, but one-time excessive entertainment and motion easily cause the body of the old people to be damaged, and at present, after the old people excessively move and play, only workers remind and advise, time nodes of the reminding and advising are uncontrollable, and the old people are difficult to persuade to have a rest, so that the current nursing home needs an intelligent system which can intelligently identify the current body state of the old people and determine whether the old people need to have a rest according to related data, and the intelligent nursing home is suitable for the current intelligent old-age community.

Based on some consideration of the above problems, the present invention aims to provide a monitoring system and a monitoring method capable of monitoring the heart rate of an elderly user in real time through an intelligent terminal, and inferring the current entertainment state of the elderly user according to the heart rate, so as to reduce the entertainment time of the elderly user reasonably, which are as follows.

As shown in fig. 1, an aging community monitoring system based on an intelligent terminal includes a main monitoring module, a warning module, and a plurality of intelligent terminals corresponding to users one by one.

The main monitoring module is provided with monitoring units corresponding to each user one by one, the monitoring units can be branch units formed by dividing the total monitoring module with cost, and the functions required by the monitoring units comprise conventional functions of receiving data, calculating data, outputting data and the like.

Elderly users have many features:

the entertainment type is standardized. Generally, entertainment provided to users of the elderly in nursing homes generally includes chess, cards, indoor sports (table tennis, indoor half-court, etc.), fitness, etc., and these entertainment are generally divided into sports and non-sports, such as mahjong and poker, which are non-sports entertainment items, so that the elderly are more likely to generate mood and heart rate fluctuation, which may affect physical health slightly, and lead to unfortunate events such as sudden cardiac death.

And the entertainment types of different old people are different. For the manager of the nursing home, the entertaining behavior is different depending on the old people, and if the same entertaining time and resting time are specified, the pertinence cannot be embodied, and the behavior of advocating the old people to rest cannot be accepted by the old people users.

Each monitoring unit is provided with a heart rate threshold value and a time threshold value corresponding to a user, and the time threshold value is the longest time of single entertainment of the user. The elderly user registers information such as age, frequent entertainment types, etc. when entering the nursing home or entering activities of the nursing home, and the information can generally give a heart rate threshold and a time threshold to each elderly user, and the determination of the two thresholds will be described in detail later.

The intelligent terminal can monitor the instant heart rate value of the user wearing the intelligent terminal and timely transmit the heart rate value to the monitoring unit.

The intelligent terminal has the function of monitoring the instant heart rate value of the user in real time and transmitting the data of the instant heart rate value to the monitoring unit. The instant heart rate value of the user who wears just can be monitored to conventional intelligent wrist-watch or intelligent bracelet in the market, and the function of transmission data also can go on through wireless mode such as bluetooth.

In the invention, the instantaneous heart rate value is also used for calculating the final time threshold value, and the instantaneous heart rate value can be adjusted through fixed parameters, so that even if the intelligent watch has a slight heart rate monitoring error relative to a professional detection machine, the influence is not too large.

An aging community monitoring method based on an intelligent terminal is applied to the aging community monitoring system and specifically comprises the following steps:

s1, before the user develops the entertainment in the community, the user wears the corresponding intelligent terminal, and when the entertainment is developed, the monitoring unit corresponding to the user starts to time the entertainment behavior of the user and records as the instant entertainment time.

When the independent entertainment behavior of each old man starts, the old man starts to time the old man until the time threshold is reached, and the old man informs the user of stopping the entertainment behavior by staff or an alarm module.

S2, the intelligent terminal transmits a first instant heart rate value of a user to the monitoring unit, the monitoring unit judges whether the instant heart rate value exceeds a heart rate threshold value, if so, the monitoring unit records a monitoring time period corresponding to the instant heart rate value into a load time period, the monitoring unit utilizes the load time period to reduce the time threshold value, and then the next instant heart rate value is judged; if not, directly judging the next instant heart rate value.

In the entertainment process of an old user, the intelligent terminal monitors heart rate information of the old in real time, and the heart rate information can be 1-3 seconds/time and is called as an instant heart rate value. If go on according to the rate of 2 seconds/time, then intelligent terminal will monitor 30 old man's heart rate in 1 minute, and then produce 30 instant heart rate values, will detect 1800 old man's heart rate in 1 hour, and then produce 1800 instant heart rate values, and so on.

The data transmission of the instant heart rate value to the monitoring unit after each monitoring of the intelligent terminal is finished, and the monitoring unit judges the currently transmitted instant heart rate value: if the current heart rate value exceeds the threshold value, the monitoring time period corresponding to the current heart rate value is counted into a load time period, for example, if the current heart rate value monitored within 2 seconds of a certain time exceeds the threshold value of the heart rate, the load time period of the user is added with 2 seconds, and the like; if not, the load period remains unchanged. Thereafter, the next instant heart rate value determination process is performed.

S3, the intelligent terminal transmits the next instant heart rate value of the user to the monitoring unit, the monitoring unit judges whether the instant heart rate value exceeds the heart rate threshold value, if so, the time period corresponding to the instant heart rate value is counted into the load time period, and the monitoring unit reduces the time threshold value again by utilizing the load time period.

In step S3, the intelligent terminal monitors the instant heart rate value and the monitoring unit determines the instant heart rate value, which are the same as those in step S2 except that step S2 is the first process of monitoring and determining the instant heart rate value, and step S3 is the next process of monitoring and determining the instant heart rate value.

And S4, repeating the step S3 until the instant entertainment time reaches the time threshold or the time threshold is reduced for a plurality of times, and terminating the entertainment behavior of the user by an alarm module or staff.

If the monitoring unit judges that the heart rate value exceeds the heart rate threshold value every time, the operation of reducing the current time threshold value is carried out once, and then the time threshold value is updated along with the advance of the entertainment time of the user. For example, the time threshold of a user is 3 hours originally, but after 1 hour of entertainment, the time threshold after reduction is only 2 and a half hours due to the load period in part.

In order to make the load time interval reduction time threshold controllable and convenient for the monitoring unit to calculate, the invention provides an algorithm formula between the load time interval and the time threshold, which is specifically as follows.

The nth instant heart rate value exceeding the heart rate threshold is recorded as h_nAnd the corresponding monitoring time period is t_nI.e. t₁、t₂、…、t_nAll belong to the load period.

Then there is T_n＝T₀-k_t·(t₁+t₂+…+t_n) Wherein T is_nFor the time threshold after the nth reduction, T₀Is an initial time threshold, k_tIs a fixed constant, n is more than or equal to 1.

Wherein the heart rate threshold is between 100-₀Between 2 and 4 hours, k_tBetween 15 and 30.

For example, when the heart rate threshold value is 105 times/minute, the intelligent terminal detects the instant heart rate value, T, at a rate of 2 seconds/time₀A value of 3 hours, k_tWhen the value is 20, a user is entertainingMusic performance was performed for 1 hour, where there were 100 heart rate values exceeding 105 beats/minute, the total length of the loading period was 200 seconds, and the reduced time thresholdThen the time that the user can continue with entertainment is 0.89 hours and this time will continue past the heart rate threshold determination to be curtailed.

Will T_n＝T₀-k_t·(t₁+t₂+…+t_n) And T_n-1＝T₀-k_t·(t₁+t₂+…+t_n-1) Subtracting to obtain T_n＝T_n-1-k_t·t_nThe formula is how the monitoring unit calculates the time threshold after the nth reduction according to the instant heart rate value after the nth-1 reduction is performed on the time threshold. Generally speaking, the monitoring unit also uses this formula to perform real-time calculation.

Due to the parameter k_tThe magnitude of the dynamic adjustment parameter k directly influences the reduction degree of the load time period to the time threshold, and in order to enable the influence of the load time period to the time threshold to be more accurate, the invention also provides a dynamic adjustment parameter k_tAnd the size mode is used for optimizing the algorithm formula in real time.

After step S4, the monitoring method further includes the following steps:

s5, measuring the blood oxygen saturation when the current user finishes the entertainment behavior by using the blood oxygen saturation measuring instrument, and dynamically adjusting the parameter k according to the detected blood oxygen saturation_t。

If the measured blood oxygen saturation is below 95% after a user has finished the entertainment activity, the parameter k is increased_tTo 1.2 times of the original.

If the measured blood oxygen saturation is not lower than 95% after a certain user finishes the entertainment activity for 3 times continuously, the parameter k is reduced_tTo 0.8 times of the original.

Normally, the blood oxygen saturation level is in the range of 95% -99%, but after long entertainment or exercise, the blood oxygen saturation level is significantly reduced.

The blood oxygen saturation after the entertainment behavior is lower than 95%, which represents that the entertainment behavior of the user may be excessive, and the influence of the load time period on the time threshold value should be improved; after a plurality of entertainment behaviors, the blood oxygen saturation is higher than 95%, which represents that the entertainment behaviors do not influence the physical condition of the user, and the influence of the load period on the time threshold can be properly reduced. Adjusting parameter k by blood oxygen saturation_tThe pertinence of the user can be preliminarily realized.

In the process of measuring the blood oxygen saturation, the measurement can be performed after the recreational activities of sports class are finished for several minutes, because the body is not adjusted immediately after finishing the sports, and the measurement is easily low. For non-sports-like recreational activities, this can be measured at the end of the recreational activity.

The present invention also considers that there may be some error in determining the instant heart rate value only by a single heart rate threshold, for example, some loading periods are when the instant heart rate value just exceeds the heart rate threshold, and some loading periods are when the instant heart rate value far exceeds the heart rate threshold, but the two cases have the same influence on the time threshold in the algorithm formula.

For this problem, the invention takes a phased threshold, i.e. a heart rate threshold is further subdivided into a fatigue threshold, and a risk threshold with a value above the fatigue threshold.

As shown in fig. 2, the monitoring time period corresponding to the immediate heart rate value exceeding the fatigue threshold and not exceeding the risk threshold is the loading time period, the monitoring time period corresponding to the immediate heart rate value exceeding the risk threshold is the risk time period, and the monitoring unit utilizes the loading time period and the risk time period to reduce the time threshold.

In order to enable the time threshold values of the load time period and the dangerous time period to be controllable and facilitate the calculation of the monitoring unit, the invention provides an algorithm formula of the time threshold values, and the algorithm formula is as follows.

The m-th instant heart rate value exceeding the fatigue threshold and not exceeding the danger threshold is recorded as h_mAnd the corresponding monitoring time periodIs a_mI.e. a₁、a₂、…、a_mAll belong to the load time period; the nth instant heart rate value exceeding the danger threshold is recorded as h_rAnd the corresponding monitoring time period is b_rI.e. b₁、b₂、…、b_rAll belong to the dangerous period.

Then there is T_m+r＝T₀-k_a·(a₁+a₂+…+a_m)-k_b·(b₁+b₂+…+b_r) Wherein T is_m+rTime threshold after m + r times of reduction, T₀Is an initial time threshold, k_a、k_bAll are fixed constants, m is more than or equal to 1, and r is more than or equal to 1.

Wherein the fatigue threshold is between 100 and 120 times/min, the risk threshold is above 120 times/min, T₀Between 2 and 4 hours, k_aBetween 15 and 30, k_bBetween 30 and 40.

For example, the fatigue threshold value is 105 times/min, the risk threshold value is 120 times/min, T₀At a value of 4 hours, k_aThe value 20, k_bTaking the value of 30.

If a user performs 1 hour in an entertainment behavior, the intelligent terminal monitors at a rate of 2 seconds/time, 3600 instant heart rate values are monitored by the intelligent terminal within 2 hours, and are calculated by the monitoring unit, wherein 40 instant heart rate values exceed the fatigue threshold but do not exceed the danger threshold, and 20 instant heart rate values exceed the danger threshold.

Then there isMeaning that 2.17 hours will be the reduced time threshold after the current instant heart rate value is judged complete, then the 2 hours that have been entertained are subtracted, the remaining entertainment time is 0.17 hours, and the remaining entertainment time should also be reduced by the periods of stress and danger.

Further, the heart rate threshold may be differentiated not only into two interval thresholds but also into an infinite number of intervals, and finally, different instant heart rate values each exceeding 100 times/min are given different degrees of influence on the time threshold.

The invention takes into account that different initial time thresholds T should be provided specifically for users of different ages who are engaged in different entertainment projects₀. The present invention is further improved as follows.

Initial time threshold T corresponding to each user₀Age A, entertainment type BAnd when the entertainment type is sports type, the value of B is 1, and when the entertainment type is non-sports type, the value of B is 0.

For example, if a user is 70 years old and performing an athletic type of entertainment activity, then the initial time threshold is

The invention discloses an intelligent entertainment time monitoring system applied to an old community, which aims to help the working personnel of the old community to persuade old users directly and convincingly and pay attention to rest when the entertainment behavior should be stopped, so as to achieve the following technical effects:

1. the entertainment time of the user is connected with the heart rate change in the entertainment process of the user, if the heart rate exceeds a normal value in the entertainment time, namely exceeds a heart rate threshold value, the emotion, blood pressure and the like of the user are judged to be obviously increased at the moment, if the entertainment activity is continued according to the originally specified entertainment time, physical diseases are possibly caused, and the entertainment time is reduced through the time period of the heart rate change; by means of the setting, on one hand, the heart rate change of the user is monitored constantly during entertainment activities of the user so as to infer the current emotion and body state and dynamically adjust the current entertainment time; on the other hand, the entertainment time of the crowd with different states and different motion types is inconsistent, and the pertinence of different users is realized; meanwhile, a normative rest system can be realized, so that staff stopping entertainment behavior can reasonably carry out persuasion work, and users can accept dynamically adjusted entertainment time.

2. The invention sets a single time threshold value of the maximum entertainment time for each user, and calculates a new time threshold value after reduction through a formula of the relation between the time threshold value and the load time period, so that the monitoring system can calculate and count the maximum value of the current entertainment time of all users in real time, the users can conveniently control the entertainment time of themselves, and the monitoring work of workers to the users is facilitated.

3. The invention quantifies partial parameters in the formula of the time threshold, wherein the normal heart rate of the user between 100 times/min and 120 times/min of the heart rate threshold is 60 to 100 times/min, and the normal entertainment time in the nursing home is about 3 hours, which is the reason that the initial time threshold is 2 to 4 hours, and the constant k is fixed_tThe values of the time threshold are obtained from multiple experiments, and the parameters quantify the relation between the reduced time threshold and the initial time threshold, so that the total monitoring module can count and monitor the time threshold conveniently.

4. By introducing the step of monitoring the blood oxygen saturation, the time threshold formula corresponding to each user can presume whether the current entertainment behavior is excessive according to the blood oxygen saturation of the user after the entertainment behavior is finished, so that the formula is dynamically adjusted, optimized, rationalized and improved.

5. The invention further develops two different thresholds on the basis of the original heart rate threshold, namely a fatigue threshold and a danger threshold, wherein the danger threshold has a larger value, and the time threshold reduced by the danger threshold has a larger value compared with the fatigue threshold under the same time length, so that the sudden high heart rate state of the user is limited by the two thresholds; when the heart rate exceeds the fatigue threshold value, the user enters a moderate fatigue state, and when the heart rate exceeds the danger threshold value, the user enters a severe fatigue or severe emotional fluctuation state, so that the entertainment time of the time is reduced, and the change of the time threshold value is more fit with the actual state of the user.

6. The initial time threshold value is also calculated in detail through a formula, the formula couples the initial time threshold value with the age and the entertainment type of the user so as to preliminarily guess a reasonable initial time threshold value suitable for the user, and the initial purpose of the design is to provide different initial time threshold values for users of different ages and different entertainment types.

While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
