[0040] The embodiments of the present invention will now be described in further detail with reference to the accompanying drawings.

[0041] This invention provides an overall structural diagram of an embodiment of a smart elderly care big data management system, comprising:

[0042] Please see Figures 1-9 This embodiment of a smart elderly care big data management system includes a mounting frame 1. A mounting groove 2 is formed on the side wall of the mounting frame 1. A detection head 3 is slidably connected to the inner wall of the mounting groove 2. A snap-fit ​​assembly 4 is fixed to both side walls of the mounting groove 2. The snap-fit ​​assembly 4 includes multiple first springs 401, and a movable plate 402 is fixed to the other end of each first spring 401. A guide rod 403 is fixed to the side wall of the movable plate 402. Movable grooves 404 are formed on both sides inside the mounting frame 1. A sliding groove 405 is formed at one end of each movable groove 404. A limiting block 406 is fixed to the inner circumference of the sliding groove 405. A movable rod 407 is slidably connected to the inner circumference of the movable groove 404. A spiral groove 408 is formed on the outer circumference of the movable rod 407. A retaining ring 409 is fixed to one end of the outer circumference of the movable rod 407. A limiting groove 410 is formed in the middle of the outer circumference of the retaining ring 409. A protective assembly 5 is snapped to the top of the mounting groove 2. A heart vibration detection module 6 is embedded in the side wall of the detection head 3. The other side of the detection head 3... A handle 7 is fixed to the side wall, and a finger pulse detection module 8 is embedded in the top of the handle 7. When the elderly person holds the handle 7, they can manually push the detection head 3 to move the moving plate 402 inward, thereby causing the guide rod 403 to move the moving rod 407. Then, the retaining ring 409 moves to one end of the slide groove 405. The guide rod 403 drives the moving rod 407 to rotate along the spiral groove 408, thereby causing the retaining ring 409 to rotate to the inside of the slide groove 405. The detection head 3 is removed and the heart vibration detection module 6 is brought close to the elderly person's chest to detect the heart vibration signal. At the same time, the finger is pressed against the top of the finger pulse detection module 8 to detect the finger photoplethysmography pulse wave signal. This allows for direct detection of the elderly person's heart rate, blood pressure and other health data, effectively improving the big data management effect. The moving plate 402 is moved and reset by the rebound force of the first spring 401. After stopping use, the detection head 3 is inserted into the side wall of the protruding mounting groove 2 on the other side to lock the detection head 3 in place, preventing the detection head 3 from falling and being damaged, and making it easy to disassemble and use.

[0043] It is worth noting that, in order to protect the finger pulse detection module 8, the protective component 5 specifically includes a positioning groove 501 opened at the top of the mounting groove 2. A positioning plate 502 is slidably connected to the side wall of the positioning groove 501. The two side walls of the positioning plate 502 are provided with slots 503. A protective velvet cloth 504 is glued to the bottom of the positioning plate 502. The two side walls of the positioning groove 501 are provided with grooves. A second spring 505 is fixed to the inner wall of each of the two grooves. A locking block 506 is fixed to the other end of each of the two second springs 505. When the positioning plate 502 is inserted into the positioning groove 501, the locking block 506 is squeezed, thereby causing the locking block 506 to move into the groove. The rebound force of the second spring 505 drives the locking block 506 to move into the groove, which helps to protect the finger pulse detection module 8 and prevents scratches on the surface of the finger pulse detection module 8 from affecting its use.

[0044] Next, in order to improve stability, specifically, multiple telescopic rods 411 located on the inner wall of the first spring 401 are fixed on the side wall of the moving plate 402. The other end of the telescopic rod 411 is fixedly connected to the inner wall of the mounting groove 2. The width of the moving plate 402 is smaller than the distance between the heart vibration detection module 6 and the side wall of the detection head 3. The telescopic rods 411 facilitate the improvement of the stability of the moving plate 402 when it moves.

[0045] Meanwhile, to facilitate the provision of rotation space, specifically, the length of the limiting block 406 is less than the length of the slide groove 405, the size and position of the limiting block 406 match the size and position of the limiting groove 410, the size and position of the spiral groove 408 match the size and position of the guide rod 403, and the cross-section of the slide groove 405 is semi-circular. The limiting block 406, whose length is less than that of the slide groove 405, facilitates the provision of space for the circlip 409 to rotate. The limiting block 406, whose size and position match that of the limiting groove 410, facilitates more stable movement of the circlip 409. The spiral groove 408, whose size and position match that of the guide rod 403, facilitates the rotation of the moving rod 407 when the guide rod 403 moves. The semi-circular slide groove 405 facilitates the accommodation of the circlip 409.

[0046] It is worth noting that, in order to prevent the positioning plate 502 from falling off, specifically, the width of the protective velvet cloth 504 is greater than the width of the finger pulse detection module 8, and the width of the protective velvet cloth 504 is less than the width of the positioning plate 502. By using the protective velvet cloth 504, which is wider than the finger pulse detection module 8, the protection of the finger pulse detection module 8 is more adequate. By using the positioning plate 502, which is wider than the protective velvet cloth 504, the positioning plate 502 is prevented from falling off.

[0047] Secondly, in order to facilitate the movement of the card block 506, specifically, the cross-section of the card slot 503 is an equilateral triangle. The size and position of the card slot 503 match the size and position of the card block 506. Through the equilateral triangle card slot 503 that matches the size and position of the card block 506, it is easy for the positioning plate 502 to be inserted or pulled out to squeeze and drive the card block 506 to move.

[0048] Next, to facilitate data transmission, specifically, the bottom of the detection head 3 is electrically connected to a transmission line 9, and the bottom of the mounting slot 2 is provided with a receiving slot 10. The heart rate and blood pressure data sensed by the heart vibration detection module 6 and the finger pulse detection module 8 are transmitted through the transmission line 9, and the receiving slot 10 facilitates the storage of the transmission line 9.

[0049] Furthermore, to facilitate big data management, specifically, a management module 11 is embedded at one end of the side wall of the mounting frame 1, and a data acquisition module 12 is embedded at the other end of the side wall of the mounting frame 1. The data acquisition module 12 is electrically connected to the management module 11, and the other end of the transmission line 9 is electrically connected to the management module 11. The facial features of the elderly are collected through the data acquisition module 12, and big data management is performed through the management module 11.

[0050] Then, in order to facilitate the installation of the mounting bracket 1, specifically, a fixing plate 13 is fixed on one side of the top and one side of the bottom of the mounting bracket 1. The side walls of the two fixing plates 13 are provided with screw holes 14. The fixing plates 13 are fixed by screwing bolts into the screw holes 14, thereby facilitating the fixed installation of the mounting bracket 1.

[0051] Finally, to facilitate the determination of the validity of the test report, a grip pad 15 is fixedly provided on the inner wall of the handle 7. The grip pad 15 is made of vulcanized rubber. Multiple arc-shaped grooves are opened on the side wall of the grip pad 15. The grip pad 15 made of vulcanized rubber improves the grip feel for the elderly and adapts to the finger position through the arc-shaped grooves, thereby improving the comfort of the elderly.

[0052] Big data management processes include:

[0053] The acquisition module and sensing module are specifically the heart rate and blood pressure data sensed by the cardiac vibration detection module 6 and the finger pulse detection module 8, and the facial data of the elderly collected by the acquisition module 12.

[0054] The management module, specifically management module 11, processes big data;

[0055] The automatic integration module specifically integrates the collected data.

[0056] The feature extraction module specifically identifies anomalous data.

[0057] The analysis module specifically involves importing and analyzing the past health data of elderly people collected by the ledger module and the health data of other elderly people in the database module.

[0058] The reporting module is specifically designed to export relevant data for managing the health status of the elderly.

[0059] The feature extraction module includes:

[0060] S1: Isolation Forest, specifically an unsupervised learning algorithm, belonging to the ensemble decision tree family;

[0061] S2: Remove outliers, specifically using the Isolation Forest method to isolate outliers, thereby eliminating abnormal and duplicate data;

[0062] S3: Principal Component Analysis, specifically a method that uses a few important principal components after standardization as common factors. The steps are: selecting key variables, eliminating the influence of dimensions, retaining the first 6-8 principal components, constructing a projection matrix, and generating principal component data.

[0063] S4: Polynomial interpolation method, specifically, is a method of approximating the minimum point of function f(t) by using the minimum point of the interpolation polynomial φ(t). The specific steps are: find the root of φ′(t) = 0 as an approximation of the minimum point of f(t), and repeat this method for iterative calculation until the accuracy requirement is met. The obtained data is then filled into the principal component data. The steps are: key node selection, sample balancing, cross-validation, least squares fitting, and interpolation to supplement the data related to elderly health.

[0064] S5: Principal component data, specifically the data obtained from the derived principal component method;

[0065] S46: Reliability data, specifically the data after removing outliers and using interpolation to fill in the gaps, is exported to the analysis module. This facilitates the removal of outliers during data acquisition and prevents unexpected interference from affecting data management.

[0066] In addition, the circuits, electronic components, and modules involved in this invention are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this invention does not involve improvements to the internal structure and methods.

[0067] Combination Figures 1-9 The specific usage process of the smart elderly care big data management system in this embodiment is as follows:

[0068] 1. When this device is needed for use in the smart elderly care big data management system, the elderly person holds the handle 7 and manually pushes the detection head 3 to move the moving plate 402 inward, thereby causing the guide rod 403 to move the moving rod 407. Then, the retaining ring 409 moves to one end of the slide groove 405. The guide rod 403 drives the moving rod 407 to rotate along the spiral groove 408, thereby causing the retaining ring 409 to rotate to the inside of the slide groove 405. The detection head 3 is taken out and the heart vibration detection module 6 is brought close to the elderly person's chest to detect the heart vibration signal. At the same time, the fingers are pressed against the top of the finger pulse detection module 8 to detect the finger photoplethysmography pulse wave signal. The rebound force of the first spring 401 drives the moving plate 402 to move and reset. After stopping use, the detection head 3 is inserted into the side wall of the protruding mounting groove 2 on the other side to lock the detection head 3.

[0069] 2: Insert the positioning plate 502 into the positioning groove 501 and press the card block 506, thereby moving the card block 506 into the groove. The rebound force of the second spring 505 drives the card block 506 to move into the card slot 503. The isolated forest method removes outliers and the polynomial interpolation method fills the data.

[0070] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
