During walking, the foot is the starting point of the most exertion and the base of the walking support of the human body, and during the walking process, the stress condition of the foot is that the sole pressure center is gradually transferred from the heel to the front sole area corresponding to the second finger, then transferred to the area corresponding to the first finger at the moment of leaving the ground, and the process is repeated in a circulating way. Therefore, whether the walking gait of the human body is normal can be judged by detecting and analyzing the pressure of the sole and the transfer of the pressure center, and then the falling risk in the walking process is judged in advance.
At present, the method for analyzing human gait by pressure signal acquisition and feedback is widely applied in the fields of medical treatment, health care and nursing. On the basis, in order to improve the accuracy of the judgment, in the prior art, the accuracy of the judgment is even improved by a threshold judgment mode, a neural network signal judgment mode or a combination mode of the threshold judgment mode and the neural network signal judgment mode. Based on threshold judgment, the judgment is mainly carried out by comparing independent data such as pressure, frequency and the like with one or more preset thresholds, the implementation complexity of the method is low, but the detection precision is relatively poor, and the false detection rate is relatively high; the method is a detection method based on mode discrimination of machine learning, a neural network model is constructed by extracting data features, and data is accurately analyzed through deep learning of the neural network model, so that falling risks under various complex conditions can be judged, the possibility of misjudgment is greatly reduced, and the reliability is improved.
However, the core of such a fall early warning system still lies in performing early warning reminding, positioning pushing and the like on a guardian, a medical staff or a user, but the system does not have the protection for old people to fall, that is, the system cannot directly reduce the fall risk of the old people, and more emphasis is placed on follow-up measures and remedial measures after the fall.

Detailed Description
As shown in fig. 1 to 7, a fall early warning system based on neural network signals comprises a detachable sole 1 capable of being installed at the bottom of a flat sole and a pose adjusting device arranged in the sole. The detachable sole 1 and the pose adjusting device are matched based on a neural network, the detecting device with the autonomous deep learning function is used, the detecting device is used for accurately detecting the falling risk of a user, the detection distance can be detected through the change trend of the pressure of the sole of a foot, the acceleration of the waist and the like, the deep learning function of the neural network is matched, the detection accuracy can be greatly improved, the false detection rate is reduced, a falling risk detecting method adopting the neural network deep learning is widely disclosed in the prior art, and the falling risk detecting method is not repeated in the invention. And the pose adjusting mechanism is used for applying a correction thrust to the foot so as to prevent falling. The detachable sole 1 is used for being installed on a flat shoe used by a user in daily life, and is convenient to detach and install.
Regarding how to adjust the position and orientation, a transverse supporting plate 6 is arranged in the installation cavity 5, two strip-shaped installation openings 7 are symmetrically arranged on the left side and the right side of the front end and the rear end of the transverse supporting plate 6, the installation openings 7 extend along the front-rear direction of the sole main body 2, and an action opening 8 is arranged at the bottom of the sole main body 2 corresponding to each installation opening 7. That is, the horizontal support plate 6 is provided with 4 mounting ports 7 in total, two on the left and right sides of the front end and two on the left and right sides of the rear end, but may be increased or decreased as appropriate according to actual circumstances. Here, the present invention takes 4 mounting ports 7 and 4 actuating ports 8 as an example. The pose adjusting device comprises adjusting mechanisms which are correspondingly arranged at each group of the mounting openings 7 and the action openings 8, and a controller 9 which is arranged between the transverse plate 3 and the transverse supporting plate 6 in the middle of the sole main body 2. The adjusting mechanism acts under the general control of the controller 9 and is used for supporting each part of the sole main body 2 so as to adjust the pose thereof.
As shown in fig. 2-6, the adjusting mechanism includes two sliding blocks 10 disposed on the upper surfaces of the horizontal supporting plates 6 on the left and right sides of the mounting opening 7, and a sliding fit along the front and rear directions of the sole main body 2 is formed between the sliding blocks 10 and the horizontal supporting plates 6, which is formed in many sliding fit manners, for example, a guide hole is disposed in the sliding block 10, a guide rod is disposed on the horizontal supporting plate 6, and the guide rod is inserted in the guide hole to form a guide fit. Of course, in order to improve the compactness of the layout and the stability of the movement of the sliding block 10, the invention may be better implemented by matching the height of the sliding block 10 with the distance between the transverse supporting plate 6 and the transverse plate 3, and forming the limit in the height direction through the transverse plate 3 and the transverse supporting plate 6. The left and right sides at slider 10 top and bottom all is provided with the sliding tray 27 that extends along sole main part 2 fore-and-aft direction, correspond on horizontal layer board 6 and the diaphragm 3 and be provided with the guide rail 28 with sliding tray 27 matched with, guide rail 28 card is established in sliding tray 27. The sliding groove 27 and the guide rail 28 form guiding and limiting, so that the moving stability of the sliding block 10 can be improved.
As shown in fig. 6, one end of the slider 10 away from the center of the sole body 2 is provided with a first kidney-shaped hole 11, and in fig. 2, one end away from the center of the sole body 2, that is, the left end of the slider 10 on the left side and the right end of the slider 10 on the right side, are provided with first kidney-shaped holes 11; the first kidney-shaped hole 11 extends vertically and penetrates through the slider 10 along the left-right direction. The adjusting mechanism further comprises an adjusting rod 12 and a driving component for driving the sliding block 10 to move along the front and back directions of the sole main body 2. The upper portion of adjusting pole 12 middle section is articulated with the left and right sides wall of installing port 7, and the lower extreme of adjusting pole 12 sets up supports horizontal pole 13, and the upper end of adjusting pole 12 is provided with first waist shape hole 11 matched with, along the first cover 14 that rotates of left and right directions extension, first cover 14 that rotates wears to establish in first waist shape hole 11. In this way, as shown in fig. 2 and 3, the adjustment lever 12 is driven to swing about the hinge center by the movement of the slider 10 in the left-right direction in the drawing (i.e., the front-rear direction of the shoe sole body 2), thereby forming a height support by the support rail 13 at the lower end of the adjustment lever 12. Since the support cross bar 13 at the lower end of the adjusting rod 12 is in contact with the ground, a rubber anti-slip sleeve 26 is sleeved outside the support cross bar 13 to improve the anti-slip and wear-resisting properties. In a normal state, the adjusting rod 12 is retracted into the actuating opening 8 and is driven to swing out only when height support is required.
In the using process, the falling risk of the user is accurately evaluated through the detection and analysis device based on the neural network signals, which is consistent with the prior art; after detecting accurate risk of falling, controller 9 control drive assembly action, and drive assembly control slider 10 motion, and then drive through the motion of slider 10 and adjust pole 12 motion for the lower extreme of adjusting pole 12 pops out fast, forms the support, and through many regulation poles 12 in coordination, and then change sole main part 2's position appearance, provide the auxiliary stay for user's foot, prevent that it from falling. The invention adopts the swing of the adjusting rod 12 to adjust the pose, so the reaction speed is very quick. Meanwhile, an oblique supporting force is essentially provided in the process of swinging the adjusting rod 12 instead of the vertical supporting force in the traditional mode, so that the falling prevention effect is better. For example: when the user leans backward, the adjustment lever 12 located at the rear end of the sole main body 2 swings out to raise the sole main body 2. Since the movement of the adjustment lever 12 is a front-to-rear swing, it provides in effect a rear, forward, diagonal inference of the foot. In addition, the adjusting rod 12 is driven to move by the movement of the slider 10 in the front-rear direction of the sole main body 2, so the overall layout is more compact, the overall thickness of the detachable sole is reduced, and the use is more convenient. Compared with a mode of adopting the air cylinder and the electric push rod to extend out in the vertical direction for height support, the novel multifunctional electric support is thinner in overall thickness and light in wearing under the same support height margin.
As for how to drive the slider 10 to move in the front-back direction, a transverse electric push rod, a transverse air cylinder push rod, and the like can be arranged, but on one hand, the reaction speed of the driving components is slow, and on the other hand, under the condition of meeting the thrust requirement and the miniaturization requirement, the electric push rod, the transverse air cylinder push rod, and the like are high in cost, and in order to reduce the overall use cost, a more sufficient transverse thrust is provided for the slider 10. As shown in fig. 6, a second kidney-shaped hole 15 which extends in the left-right direction and vertically penetrates through the slider 10 is formed in one end, close to the center of the sole main body 2, of the slider 10, a relief groove 16 which extends in the left-right direction is formed in the end face, close to the center of the sole main body 2, of one end of the slider 10, and the relief groove 16 penetrates through the second kidney-shaped hole 15. As shown in fig. 5, the driving assembly comprises a bridging plate 17 which is arranged across the mounting opening 7, two vertical pins 18 are arranged between the top of the bridging plate 17 and the transverse plate 3, and the pins 18 are symmetrically distributed at two ends of the bridging plate 17. The driving assembly further comprises a driving swing rod 19, a pin sleeve 20 matched with the pin 18 is arranged in the middle section of the driving swing rod 19, and the pin sleeve 20 is sleeved on the pin 18 and hinged to the pin 18. One end of the driving swing rod 19 is provided with a vertical second rotating sleeve 21, and the second rotating sleeve 21 is arranged in the second kidney-shaped hole 15 in a penetrating mode. The driving swing link 19 of the present invention essentially forms a lever, and a force is amplified by the lever, and the driving swing link 19 can amplify the force and transmit the amplified force to the slider 10 to drive the slider 10 to move by applying a force to one end of the long moment of the driving swing link 19. That is, the driving assembly further includes a driving member provided at the other end of the driving swing link 19 for driving the driving swing link 19 to swing about the pin 18. The driving part is electrically connected with the controller 9. In order to ensure the sensitivity and rapidity of the driving means, the electromagnet 22 is preferably chosen for said driving means. As shown in fig. 4, when the electromagnet 22 is energized, its two-stage magnetization is of corresponding polarity, which in turn drives the driving levers 19 to close and open.
Of course, in order to ensure that the position of the electromagnet 22 can be adjusted in a self-adaptive manner in the process of rotating along with the driving swing rod 19, as shown in fig. 7, one end of the driving swing rod 19 opposite to the electromagnet 22 is provided with a U-shaped mounting frame 24, a rotary adjusting frame 25 is arranged between two branches of the mounting frame 24, and pin shafts at the upper end and the lower end of the rotary adjusting frame 25 penetrate through the two branches of the mounting frame 24 and form a rotating fit with the branches. The electromagnet 22 is fixedly arranged in the rotary adjusting frame 25. It is anticipated that the angular adjustment of the rotary adjustment bracket 25 relative to the mounting bracket 24 should be a slight adjustment, which is merely to allow for a displacement of the electromagnet 22 during rotation of the drive rocker 19, rather than a complete free rotation, which is typically around 2-5 °. The specific angle limiting mode can be achieved by referring to the prior art, and only by arranging limiting blocks in pin holes of the pin shaft and the mounting frame 24, which is not described in detail in the invention.
In addition, in order to maximize the utilization of the two-pole magnetism of the electromagnet 22, a permanent magnet 23 is further disposed at a position where the left and right side walls of the sole main body 2 are opposite to the electromagnet 22, and the magnetic pole attribute of the end of the permanent magnet 23 opposite to the electromagnet 22 is the same as the magnetic pole attribute of the electromagnet 22 when the two driving swing rods 19 of the driving assembly are folded. As shown in fig. 4, the polarity of the electromagnet 22 is indicated at both ends in an energized state, in which the drive rocker 19 is driven to close. In the case of reverse energization, the drive rocker 19 is then disengaged. But because of the particular arrangement shown in the figures, the magnetic properties at both ends of each electromagnet 22 are maximally utilized.
