Description

Technical Field

[0001] The present invention relates to smart elderly care, and in particular to a smart elderly care monitoring system for monitoring the vital signs of the elderly. Background Art

[0002] Smart elderly care is a sensor network system and information platform for elderly people at home, communities and elderly care institutions, and on this basis provides real-time, fast, efficient, low-cost, IoT-based, interconnected and intelligent elderly care services. Since smart elderly care can improve the quality of elderly care services and make elderly care services more comprehensive, smart elderly care is gradually becoming popular in the elderly care service industry. The current smart elderly care monitoring can monitor the vital signs of the elderly in real time and report abnormal information when abnormal vital signs occur.

[0003] For example, the prior art with publication number CN108401415B inputs the body temperature, blood pressure and heart rate into the three-dimensional coordinate system of the physical health index model, obtains a coordinate point in the three-dimensional coordinate system; calculates the distance between the coordinate point and the center point of the three-dimensional coordinate system, and determines whether the distance is greater than a first threshold; when the distance is greater than the first threshold, determines that the physical state of the monitored object is abnormal. However, when the elderly are exercising, their blood pressure, heart rate and body temperature will all increase. Therefore, this solution is prone to false alarms of abnormalities when normal elderly people are exercising. Summary of the invention

[0004] Purpose of the invention: The purpose of the present invention is to provide a smart elderly care monitoring system that is convenient for monitoring the vital signs of the elderly.

[0005] Technical solution: A smart elderly care monitoring system that is convenient for monitoring the vital signs of the elderly. The system includes three parts: monitoring terminal, data service and monitoring terminal, among which: The monitoring terminal part includes an information data acquisition module, an information data processing module, and a real-time data sending module; the information data acquisition module is used to collect vital signs information data of the elderly, and is also used to obtain the exercise intensity information data of the elderly; the information data processing module is used to process the information data acquired by the information data acquisition module; the real-time data sending module is used to send the information data processed by the information data processing module to the data service part; The data service part includes a real-time data receiving module, a data storage module, a core analysis module, a data extraction module and an abnormal notification module; the real-time data receiving module is used to receive information data sent by the real-time data sending module; the data storage module is used to store the information data received by the real-time data receiving module; the core analysis module is used to analyze the information data received by the real-time data receiving module to obtain the elderly's guardianship index, and judge whether the elderly need to be focused on according to the guardianship index, and send the abnormal information to the guardian after the elderly's guardianship index is abnormal; the data extraction module is used to extract the elderly's vital signs information data from the data storage module and send it to the guardianship terminal of the guardian after the core analysis module judges that the elderly need to be focused on according to the guardianship index of the elderly; the abnormal notification module is used to notify the guardian of the abnormal information after the elderly's guardianship index is abnormal; the data sending module is used to send the information that the data extraction module and the abnormal notification module need to send to the monitoring terminal part; The monitoring terminal part includes a data receiving module and an information display module; the data receiving module is used to receive information data sent by the data sending module; the information display module is used to display the information data received by the data receiving module.

[0006] Preferably, the information data acquisition module includes two parts: vital signs information monitoring and collection and exercise intensity monitoring and collection; the vital signs information monitoring and collection is used to collect the elderly's heart rate, blood pressure and body temperature information data; the exercise intensity monitoring and collection is used to collect the elderly's activity intensity information data.

[0007] Preferably, in the process of monitoring and collecting the exercise intensity of the elderly, the maximum heart rate of the elderly is first obtained according to the age of the elderly = 220-age, and then the exercise intensity of the elderly is obtained according to the ratio of the average heart rate of the elderly over a period of time and the maximum heart rate of the elderly.

[0008] Preferably, when the information data processing module processes the information collected by the information data acquisition module, it includes cleaning the collected information data and converting the collected information data.

[0009] Preferably, in the process of analyzing the data, the core sub-module first retrieves the corresponding information data from the data storage module, and then converts the retrieved information data into a data format that can be processed and analyzed by the core analysis module. After the conversion is completed, the converted information data is analyzed to obtain the guardianship index of the elderly, and based on the comparison between the guardianship index and the threshold, it is judged whether the elderly needs to be focused on and whether there is any abnormality in the guardianship index of the elderly. When it is judged that the elderly needs to be focused on, the judgment result is sent to the data extraction module, and when it is judged that there is an abnormality in the guardianship index of the elderly, the judgment result is sent to the abnormal notification module.

[0010] Preferably, when generating the monitoring index of the elderly, the core analysis module obtains the elderly's heart rate HR, diastolic blood pressure DBP, systolic blood pressure SBP, body temperature T and exercise intensity Q per minute from the data storage module over a period of time, so as to obtain the average heart rate change ΔHR, the average diastolic blood pressure change ΔDBP, the average systolic blood pressure change ΔSBP and the average body temperature change ΔT of the elderly per minute.

Similarly, the position of each guardian is obtained according to the three-circle positioning principle, and the guardian with the smallest horizontal distance and vertical distance from the elderly with abnormal guardianship index is selected as the optimal guardian, where the horizontal distance and vertical distance from the elderly with abnormal guardianship index are: ; Among them, x is the horizontal distance from the elderly with abnormal monitoring index, a1 is the distance between a base station and the guardian, b1 is the distance between a base station and the elderly with abnormal monitoring index, c is the distance between the two base stations, a2 is the distance between another base station and the guardian, b2 is the distance between another base station and the elderly with abnormal monitoring index, y is the vertical distance from the elderly with abnormal monitoring index, h p is the distance between the guardian and the positioning satellite, h oThe distance between the elderly person with abnormal monitoring index and the positioning satellite.

[0012] Preferably, data is transmitted between the real-time data sending module and the real-time data receiving module, and between the data sending module and the data receiving module using 4G / 5G communication method. Beneficial Effects

[0013] (1) The present invention generates a monitoring index based on the changes in the heart rate, blood pressure, body temperature and activity intensity of the elderly over a period of time, so that the currently generated monitoring index can be compared with the preset threshold parameters to determine whether the elderly need to be monitored intensively. When it is determined that the elderly need to be monitored intensively, the current vital sign information data of the elderly is extracted and sent to the guardian, and the guardian is reminded when the monitoring index changes, so that the guardian can understand the vital signs of the elderly in real time, which is convenient for the guardian to make real-time adjustments to the monitoring of the elderly.

[0014] (2) The present invention introduces the exercise intensity index when generating the monitoring index, which can avoid the occurrence of false alarms due to changes in vital sign information data when the elderly are exercising, thereby ensuring the accuracy of monitoring.

[0015] (3) After determining that an abnormality has occurred in the elderly's monitoring index, the present invention will automatically select the best monitoring personnel, send the elderly's vital signs information and abnormality notification information to the best monitoring personnel, and notify the best monitoring personnel to go and handle the situation, thereby ensuring the timeliness of emergency handling. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a schematic diagram of the system principle of the present invention; Figure 2 It is a schematic diagram of the system structure of the present invention; Figure 3 , 4 It is a schematic diagram of selecting the optimal guardian according to the present invention. DETAILED DESCRIPTION

[0017] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0018] like Figure 1-2As shown in the figure, a smart elderly care monitoring system for monitoring the vital signs of the elderly is composed of three parts: a monitoring terminal composed of a mobile wearable terminal (such as a wristwatch), a data service composed of a data server, and a monitoring terminal composed of a portable monitoring terminal (such as a mobile phone, a tablet, a notebook, etc.). The mobile wearable terminal is worn on the body of the elderly who need to be monitored, and the monitoring personnel carry the portable monitoring terminal.

[0019] The monitoring terminal collects the heart rate, blood pressure (diastolic pressure, systolic pressure) and body temperature vital signs of the elderly in real time through the information data acquisition module. At the same time, the maximum heart rate of the elderly is obtained according to the age of the elderly = 220-age, and then the exercise intensity information of the elderly is obtained according to the average heart rate collected over a period of time and the proportion of the maximum heart rate of the elderly. For example, if the average heart rate accounts for 40~54% of the maximum heart rate, it is low-intensity exercise, and its exercise intensity is 3; if the average heart rate accounts for 55~69% of the maximum heart rate, it is medium-intensity exercise, and its exercise intensity is 6; if the average heart rate accounts for 70% or more of the maximum heart rate, it is high-intensity exercise, and its exercise intensity is 9. After the above collected information data is cleaned and converted by the information data processing module, it is sent to the data service part through the real-time data sending module through the 4G / 5G communication method.

[0020] After the data service part receives the information data collected by the monitoring terminal part through the real-time data receiving module, it sends it to the data storage module for storage. Then the core analysis module retrieves the elderly's heart rate HR, diastolic blood pressure DBP, systolic blood pressure SBP, body temperature T and exercise intensity Q per minute from the data storage module over a period of time, and obtains the elderly's heart rate change average ΔHR, diastolic blood pressure change average ΔDBP, systolic blood pressure change average ΔSBP and body temperature change average ΔT per minute. After converting the retrieved data into a processable format, the elderly's monitoring index ECI is generated through the converted data: ; in, ECI The guardianship index for the elderly. ɑ , β , γ are the weight coefficients corresponding to heart rate, blood pressure and body temperature parameters, and ɑ+β+γ=1 The obtained elderly monitoring index ECI is compared with the preset threshold parameters to determine whether the elderly need to be monitored. If necessary, the elderly's vital signs information data is obtained from the data storage module in advance through the data extraction module, and sent to the monitoring terminal part through the data transmission module using the 4G / 5G communication method.

[0021] After receiving the sent information data, the data receiving module in the monitoring terminal will hand over the received information data to the information display module for display, so that the guardian can understand the vital signs of the elderly in real time, and when the vital signs of the elderly who need key monitoring change, the guardian will be reminded, so that the guardian can understand the vital signs of the elderly in real time, which is convenient for the guardian to make real-time adjustments to the monitoring of the elderly.

[0022] During the monitoring of the elderly, the heart rate, blood pressure (diastolic pressure, systolic pressure) and body temperature information of a 65-year-old man were collected every minute for 5 minutes as follows:

[0023] Therefore, we can get the current maximum heart rate of the elderly = 220-65 = 155. The current average heart rate of the elderly is about 93, so the current average heart rate of the elderly occupies 60% of the maximum heart rate. The elderly are currently doing moderate-intensity exercise, and the exercise intensity is 6. The corresponding weight coefficients of heart rate, blood pressure and body temperature when generating the monitoring index are set as ɑ=0.4 , β=0.3 , γ = 0.3 According to the information collected above, the current elderly care index ECI can be obtained as follows: ; It can be obtained that the current ECI of the elderly is less than 0.3 (preset threshold parameter). Therefore, the elderly do not need intensive monitoring at present.

[0024] In addition, the heart rate, blood pressure (diastolic pressure, systolic pressure) and body temperature information of a 76-year-old man were collected every minute within 5 minutes as follows:

[0025] Therefore, the average heart rate of the elderly currently accounts for 53% of the maximum heart rate. The elderly currently do low-intensity exercise, and the exercise intensity is 3. The corresponding weight coefficients of heart rate, blood pressure and body temperature when generating the monitoring index are set as follows: ɑ=0.4 , β=0.3 , γ =0.3 According to the information collected above, the current elderly care index ECI can be obtained as follows: ; It can be obtained that the current ECI of the elderly is greater than 0.3 (pre-set threshold parameter). Therefore, the elderly currently need intensive monitoring. Example

[0026] On the basis of Example 1, when the elderly's guardianship index ECI-0.3≥0.3×0.5, it is determined that the elderly's guardianship index is abnormal. At this time, the position of the elderly O whose guardianship index is abnormal is first obtained according to the three-circle positioning principle based on the nearby base stations (A, B, C, D, etc.). Similarly, the position of each guardian is obtained according to the three-circle positioning principle, and the guardian P with the smallest horizontal distance and vertical distance from the elderly with abnormal guardianship index is selected as the optimal guardian: ; Among them, x is the horizontal distance from the elderly O whose monitoring index is abnormal, a1 is the distance between the base station A and the guardian P, b1 is the distance between the base station A and the elderly O whose monitoring index is abnormal, c is the distance between the two base stations A and C, a2 is the distance between the base station C and the guardian P, and b2 is the distance between the base station C and the elderly O whose monitoring index is abnormal. Figure 3 As shown. y is the vertical distance from the elderly person O whose monitoring index is abnormal, h p h is the distance between the guardian P and the positioning satellite, o The distance between the elderly person O whose monitoring index is abnormal and the positioning satellite is as follows: Figure 4 The abnormal information is sent to the monitoring terminal device of the best monitoring personnel through the abnormal notification module, so that the best monitoring personnel can be notified to go and handle it, thereby ensuring the timeliness of emergency handling.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
