Description

Technical Field

[0001] The present invention generally relates to the field of footwear, and in particular to a pressure sensor for preventing falls and an implementation method thereof. Background Art

[0002] Among hospitalized patients, the number of elderly people aged 80-90 is gradually increasing. Most of the elderly can take care of themselves, but due to changes in their living environment, the risk of falling is gradually approaching.

[0003] Falling is a common dangerous event for the elderly. Falling may cause fractures, paralysis, ruptured blood vessels, loss of consciousness, etc. In severe cases, it may even cause death.

[0004] Therefore, the inventor believes that the elderly need a fall prevention device to reduce the occurrence of falls in the elderly. Summary of the invention

[0005] In view of the problems existing in the above-mentioned prior art, the present invention provides a pressure sensing shoe for preventing falls, comprising: a shoe body, the shoe body comprising a sole and an upper, a pressure sensing member arranged in the sole, the pressure sensing member comprising a forefoot pressure sensing member, at least three of which are arranged and spaced along the width direction of the forefoot; at least three lateral longitudinal arch pressure sensing members, which are spaced and distributed along the lateral area of ​​the middle part of the sole; at least three heel pressure sensing members, which are arranged and located on both sides of the heel area and the heel; a processing unit fixed on the shoe body, the processing unit comprising a processor, which is electrically connected to the forefoot pressure sensing member, the lateral longitudinal arch pressure sensing member, and the heel pressure sensing member, and is used to receive the pressure value of each pressure sensing member and the time interval data of the triggering of adjacent pressure sensing members, and analyze and compare them; a storage device, which is electrically connected to each pressure sensing member and the processor, and is used to store the triggering sequence of the pressure sensing members, the value change of the pressure sensing members, and the triggering interval time; and a sounder, which is fixed on the shoe body and electrically connected to the processor, and is used to receive the electrical signal of the processor and sound an alarm. With the above-mentioned technical features, the pressure-sensitive component is not only used to measure the pressure range value, but also needs to cooperate with the processor to measure the triggering sequence of different pressure-sensitive components, and then cooperate with the triggering intervals between the pressure-sensitive components to determine the wearer's movement posture, with posture as the main judgment direction, and use the sounder to prevent alarms.

[0006] In some embodiments, the sole includes an anti-skid layer, which is located at the bottom layer of the sole and is used for contacting the ground; a flexible support layer, which is located above the anti-skid layer and interconnected with the anti-skid layer; a surface layer, which is located above the flexible support layer and fixed to the anti-skid layer; and the pressure-sensitive element is located between the flexible support layer and the surface layer. Therefore, the pressure-sensitive element is arranged between the surface layer and the flexible support layer. On the one hand, it is closer to the footsteps, which helps to improve the measurement accuracy; on the other hand, the pressure-sensitive element is arranged above the flexible support layer, so that the pressure-sensitive element and the flexible support layer are more closely attached, which cushions the pressure-sensitive element and ensures the stability and effectiveness of the pressure-sensitive element.

[0007] In some embodiments, the processing unit is detachably connected to the upper, and a magnetic interface for electrically connecting the pressure-sensitive component and the processing unit is provided on the sole. Thus, the processing unit is detachably connected to the upper to prevent water from entering the processing unit when the shoe is cleaned, thereby extending the service life of the entire shoe.

[0008] In some embodiments, it also includes an energy supply component, which is electrically connected to the processing unit and is used to supply power to the pressure sensing component and the processing unit, thereby ensuring the independent operation of the electrical equipment in the shoe body and the stability of data measurement and acquisition.

[0009] In some embodiments, the pressure sensing member further comprises medial longitudinal arch pressure sensing members, at least two of which are provided and spaced apart along the medial area of ​​the arch of the middle part of the sole, and each medial longitudinal arch is located in the relative area between two adjacent lateral longitudinal arch pressure sensing members. Thus, the pressure data of the medial side of the arch of the foot can be fully obtained to improve the comprehensive evaluation of the footstep stability.

[0010] In some embodiments, the processing unit further includes a pedometer sensor, which is electrically connected to the processor and is used to determine whether the wearer is in a moving state or a stationary state. Thus, the pedometer sensor is small in size, economical, and has limited power consumption, which can not only make a preliminary assessment of the wearer's state, but also reduce the overall power loss in the shoe body.

[0011] In some embodiments, the processing unit further includes an air pressure sensor electrically connected to the processor for measuring changes in the height of the external environment, thereby cooperating with the determination of changes in the wearer's environment and cooperating with the algorithm to predict falls.

[0012] An implementation method includes:

[0013] Collect standing activity state data, in response to the wearer maintaining a natural standing state, perform pressure collection actions, that is, keep the body stable with the help of the external environment, and then slightly swing the body in different directions, and the body swing amplitude can keep the body balanced without moving the feet; record the floating range of the value change of each pressure-sensitive component as X1, that is, the maximum value measured by each pressure-sensitive component minus the minimum value measured by the pressure-sensitive component during the collection time, and record the X1 of each pressure-sensitive component in the storage;

[0014] Determine the alarm. If there is no change in the pedometer sensor, the wearer is determined to be in a stationary state. The floating range of the value change of the single pressure-sensitive element is set to X0. If X0 is greater than X1, that is, the wearer's body center of gravity is unstable, the processor sends an electrical signal to the sounder, and the generator sounds an alarm.

[0015] Therefore, the body's weight changes throughout the day, including the weight of food or clothing, so it is easier to reduce the error caused by weight change through the pressure difference, and measure the pressure value of the human body in a slightly tilted state to meet the wearer's normal work needs and reduce false alarms.

[0016] In some embodiments, including:

[0017] Collect the state data of the elevator state change, in response to the wearer taking the elevator up, perform the pressure collection operation, and record the floating range of the value change of each pressure-sensitive component as X2, that is, the maximum value measured by each pressure-sensitive component minus the minimum value measured by the pressure-sensitive component during the collection time; similarly, in response to the wearer taking the elevator down, perform the pressure collection operation, and record the floating range of the value change of each pressure-sensitive component as X3, that is, the maximum value measured by each pressure-sensitive component minus the minimum value measured by the pressure-sensitive component during the collection time;

[0018] Determine the alarm. If the pedometer sensor value changes within a safe range and the air pressure sensor changes significantly, it is determined that the wearer is in an elevator state, and the ascent or descent state is determined based on the change in the air pressure sensor. If the floating range of the value change of a single pressure-sensitive component is X0, X0 can be compared with X2, X3 according to the wearer's ascent and descent state; if X0 is greater than X2, X3; the wearer's body center of gravity is unstable, that is, the processor sends an electrical signal to the sounder, and the generator sounds an alarm.

[0019] Therefore, through the dual cooperation of the air pressure sensor and the pedometer sensor, the wearer's environmental wear is determined, and specific parameters are compared, making the fall prevention status determination more accurate.

[0020] In some embodiments, including:

[0021] Collect the data of the state of the moving straight road surface. In response to the wearer walking on the road, perform the pressure collection operation. At this time, the floating range of the value change of each pressure-sensitive component is X4, that is, the maximum value measured by each pressure-sensitive component minus the minimum value measured by the pressure-sensitive component during the collection time; the triggering order of all pressure-sensitive components during walking; and the interval time T1, T2, T3... of the adjacent triggering pressure-sensitive components, and the change stroke of each interval time is T1 mix -T1 max ,T2 mix -T2 max ,T3 mix -T3 max , and record the relevant data into the storage device;

[0022] Collect height change status data, respond to the wearer walking up the stairs, perform pressure collection operations, record the floating range of each pressure-sensitive component value change as X5, that is, the maximum value measured by each pressure-sensitive component minus the minimum value measured by the pressure-sensitive component during the collection time; the triggering order of all pressure-sensitive components during walking; and the interval time T4, T5, T6... of adjacent triggering pressure-sensitive components, and the change stroke of each interval time is T4 mix -T4 max ,T5 mix -T5 max ,T6 mix -T6 max , and record the relevant data in the storage; the same is true for going down the stairs, the floating range of the value change of each pressure-sensitive component is X6; during walking, the triggering order of all pressure-sensitive components; and the interval time between the adjacent triggering pressure-sensitive components is T7, T8, T9; the change stroke of each interval time is T7 mix -T7 max ,T8 mix -T8 max ,T9 mix -T9 max , and record the relevant data into the storage device;

[0023] Determine the alarm. If the value of the pedometer sensor changes, it is preliminarily determined that the wearer is in a moving state, and the next step of determination is performed; if the triggering sequence of the pressure-sensitive parts is the same as the triggering sequence of walking on a flat road, the next step of determination is performed; suppose the interval time between the triggering of adjacent pressure-sensitive parts is t0, t1, t2..., if t0, t1, t2... corresponds to T1 mix -T1 max ,T2 mix -T2 max ,T3 mix -T3 maxIf the value of a single pressure-sensitive element is within the range of X0, the next judgment is performed; if the floating range of the value change of the single pressure-sensitive element is X0, and X0 is less than or equal to X4, the sounder is in a silent state;

[0024] If the triggering sequence of the pressure-sensitive parts is different from the triggering sequence of walking on a flat road, then compare the triggering sequence of the pressure-sensitive parts when going up and down the stairs. If it is the same as the triggering sequence of the pressure-sensitive parts when going up and down the stairs, perform the next judgment; suppose the interval time between the triggering of adjacent pressure-sensitive parts is t0, t1, t2..., if it is consistent with the state of going upstairs, t0, t1, t2... corresponds to T4 mix -T4 max ,T5 mix -T5 max ,T6 mix -T6 max If it matches the upstairs state, t0, t1, t2, etc. correspond to T4. mix -T4 max ,T5 mix -T5 max ,T6 mix -T6 max Within the range, if it is in the downstairs state, t0, t1, t2, etc. correspond to T7 mix -T7 max ,T8 mix -T8 max ,T9 mix -T9 max If the value of a single pressure-sensitive element is within the range, the next judgment is performed; if the floating range of the value change of the single pressure-sensitive element is X0, and X0 is less than or equal to X4 or X5, then the sounder is in a silent state;

[0025] If the triggering sequence of the pressure-sensitive parts is different from the triggering sequence of walking on a straight road or going up and down stairs, the triggering sequence of the pressure-sensitive parts will be measured again. If the triggering sequence of the pressure-sensitive parts is different from the triggering sequence of walking on a straight road or going up and down stairs, it is determined that the wearer's center of gravity is unstable, and the processor sends an electrical signal to the sounder, causing the sounder to sound an alarm.

[0026] Therefore, the different situations of the wearer in motion can be identified, and the different external environments and the wearer's own postures can be determined by limiting multiple conditions, so as to perform targeted data comparison.

[0027] It should be understood that the contents described in the summary of the invention are not intended to limit the key or important features of the embodiments of the present disclosure, nor are they intended to limit the scope of the present disclosure. Other features of the present disclosure will become easily understood through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Hereinafter, preferred embodiments (or implementation modes) of the present invention will be described in detail with reference to the accompanying drawings.

[0036] Reference below Figure 1-Figure 5 A pressure sensing shoe for preventing falls and an implementation method thereof are described in the present invention.

[0037] Figure 1 FIG. 1 is a schematic diagram showing an exploded structure of a pressure sensing shoe for preventing falls according to an embodiment of the present invention. Figure 1As shown, a pressure sensing shoe for preventing falls includes a shoe body 1, wherein the shoe body 1 includes a sole 11 and a shoe upper 12 fixed on the sole 11. The sole 11 includes an anti-skid layer 111 at the bottom, a flexible support layer 112 located above the anti-skid layer 111, and a surface located above the flexible support layer 112. The anti-skid layer 111 can be made of hard rubber or wear-resistant material, and its bottom is provided with anti-skid patterns to ensure wear resistance in contact with the ground and friction during walking. The flexible support layer 112 is fixed on the top of the anti-skid layer 111, and can be made of hard latex material, with a relatively hard texture and a certain elasticity. For the elderly, the harder sole 11 can provide stable support force compared with the soft sole 11. The surface layer 113 is fixed on the flexible support layer 112, and its texture is relatively soft, which is used to directly contact the foot, thereby increasing the contact area with the foot through its own elastic deformation, which not only improves the comfort of the wearer after wearing the shoe, but also improves the stability during walking.

[0038] Figure 2 FIG. 1 is a schematic diagram showing the position relationship of the sensing components of a pressure sensing shoe for preventing falls according to an embodiment of the present invention. Figure 2 As shown, a pressure-sensing member 3 is also provided between the flexible support layer 112 and the surface layer 113. The pressure-sensing member 3 can be divided into four types according to the position, and includes a forefoot pressure-sensing member 31, a lateral longitudinal arch pressure-sensing member 32, a medial longitudinal arch pressure-sensing member 34, and a heel pressure-sensing member 33. At least three forefoot pressure-sensing members 31 are provided, and are located in the forefoot area, and are distributed in an arc shape along the width direction of the forefoot, so as to measure the pressure data of each area of ​​the forefoot. At least three lateral longitudinal arch pressure-sensing members 32 are provided, and are located at the arch of the foot in the middle area of ​​the foot. Since the lateral bones of the human arch are relatively stronger, the lateral longitudinal arch will bear more pressure when it is circumscribed, so the lateral longitudinal arch pressure-sensing members 32 are provided at the lateral longitudinal arch, and are arranged at intervals along the length direction of the lateral longitudinal arch. The number of the inner longitudinal arch pressure sensing elements 34 is one less than the number of the outer longitudinal arch pressure sensing elements 32 , and they are located between adjacent outer longitudinal arch pressure sensing elements 32 and close to the inner longitudinal arch, so as to cooperate with the outer longitudinal arch pressure sensing elements 32 to understand the walking posture of the wearer.

[0039] Figure 3 FIG. 2 shows a system diagram of a processing unit 2 in a pressure sensing shoe for preventing falls according to an embodiment of the present invention. Figure 3As shown, the pressure-sensitive member 3 is controlled by a driving unit, and the driving unit includes a circuit board, and a processor 21 is coupled to the circuit board. The processor 21 can be a microprocessor 21, so as to reduce its own volume occupation and be more conveniently arranged in the shoe body 1. The processor 21 mainly processes, analyzes and determines the data obtained by the pressure-sensitive member 3, including: obtaining the pressure value of each pressure-sensitive member 3, and the range of pressure change of each pressure-sensitive member 3; the order of triggering the pressure-sensitive members 3 when the shoe body 1 lands; and the time interval range between adjacent triggered pressure-sensitive members 3 in the order of triggering the pressure-sensitive members 3. The above data can analyze the changes in the walking posture of the wearer, so as to provide data support for preventing the wearer from falling. The circuit board is also coupled with a storage 22, which is electrically connected to the processor 21, so that it can be controlled by the processor 21, and is used to store the original data of each pressure-sensitive member 3, and the comparison data processed by the processor 21. Each of the pressure sensing components 3 has two circuits and is electrically connected to the processor 21 and the storage 22, respectively, so as to facilitate the conversion of the data obtained by itself into electrical signals, and transmit them to the processor 21 for processing, and store them in the storage 22 for standby. The circuit board is also coupled with a pedometer sensor 25, which is electrically connected to the processor 21. Whether the pedometer sensor 25 is triggered or not is determined to determine whether the wearer is in a moving or stationary state, which helps to cooperate with other sensors to improve the accurate judgment of the wearer's environmental information and posture information. The circuit board is also coupled with an air pressure sensor 24, which is electrically connected to the processor 21. The air pressure of the surrounding environment is obtained through the air pressure sensor 24 to understand the height information of the sensor, and cooperate with the data support of other sensors to improve the accurate judgment of the wearer's external environmental information and posture information. One side of the circuit board is also provided with an energy supply component 4, which can be a battery, which can be a button battery or a No. 7 battery, mainly according to the setting position of the processing unit 2, and the energy supply component 4 is adjusted. A sound generator 23 is also coupled to the circuit board. The processor 21 can make a judgment based on the data fed back by the pressure sensing element 3 and send an electrical signal to the sound generator 23 to control the opening and closing of the sound generator 23.

[0040] Figure 4The schematic diagram of the structure of the processing unit 2 in a pressure sensing shoe for preventing falls according to an embodiment of the present invention is shown. The processing unit 2 is arranged in a shell 5, and a cavity for accommodating a circuit board is arranged inside the shell 5. The port of the shell 5 is detachably connected to a cover body 6. The shell 5 and the cover body 6 are connected to each other, so that the internal processing unit 2 can be protected. The shell 5 is detachably connected to the upper 12, and can be fixed to the upper 12 in the heel area by Velcro. The circuit board leads out the circuit, and a magnetic suction interface 7 is arranged at the end of the circuit. The magnetic suction interface 7 is magnetically attracted to the rear side of the sole 11 and is electrically connected to each pressure-sensitive component 3 inside the sole 11, so that when the shoe body 1 is cleaned, the shell 5 and the upper 12 can be detached from each other, and the circuit can be disconnected through the magnetic suction interface 7. Moreover, the energy supply component 4 can be replaced by detaching the cover body 6 from the shell 5 to ensure the normal power supply of the electrical equipment in the shoe body 1.

[0041] Figure 5 FIG. 1 is a flow chart showing a method for implementing a pressure sensing shoe for preventing falls according to an embodiment of the present invention. Figure 5 As shown, a method for implementing pressure sensing shoes for preventing falls includes the following steps:

[0042] S1: Collect and compare databases; pressure sensing shoes are only for the elderly. People in this age group may suffer from fractures, paralysis, ruptured blood vessels, loss of consciousness, etc. after falling, and in severe cases, even death. Therefore, to improve the accuracy of the pressure sensing shoe alarm, one-to-one data collection is required. After all, everyone has different heights and weights, and different foot shapes, which also creates different walking postures. If a unified algorithm data is used, it can only be used for most people, but it is difficult to accurately adapt to everyone's walking habits. Therefore, before using pressure sensing shoes, special data materials are required, and the data information of each item is used as the standard to make the data more referenceable.

[0043] S11: Collect standing activity state data, in response to the wearer putting on the pressure sensing shoes and maintaining a standing state, perform pressure collection action; during the collection process, a guardian is required to help, or there are facilities for support around to keep the wearer's standing state stable; then keep the feet stable, the body slightly tilted to the side, the tilt angle is a body controllable state without taking a step, and then draw a circle in a tilted state, so that the body has a tilting action at all angles, and repeat the same action 3-5 times. At this time, the pressure sensing element 3 in each shoe body 1 collects the foot support force, and each pressure sensing element 3 will retain the minimum and maximum values ​​measured, and the floating range of each pressure sensing element 3 is calculated by the processor 21 as X1, that is, the maximum value measured by each pressure sensing element 3 minus the minimum value measured by each pressure sensing element 3, and the floating range X1 of each pressure sensing element 3 is recorded and saved in the storage 22.

[0044] Since each person has a different weight and foot shape, people of the same weight will have different foot shapes, which will cause deviations in the data measured by each pressure-sensitive component 3. In addition, a person's clothing weight, metabolic capacity, and daily energy intake will all cause large differences in the pressure-sensitive component 3 within a day. Therefore, the measurement data of the pressure-sensitive component 3 will not be directly selected as a reference to avoid misjudgment. Therefore, the changing floating amount of each pressure-sensitive component 3 is used as a reference, and the error is smaller.

[0045] S12: Collecting data on taking the elevator upward, in response to the wearer taking the elevator upward, performing pressure collection operations; at this time, the pressure-sensitive parts 3 in each shoe body 1 collect the foot support conditions, and each pressure-sensitive part 3 retains the minimum and maximum values ​​measured, and the processor 21 calculates the floating range of each pressure-sensitive part 3 as X2, that is, the maximum value measured by each pressure-sensitive part 3 minus the minimum value measured by each pressure-sensitive part 3, and records the floating range X2 of each pressure-sensitive part 3 and saves it in the storage 22.

[0046] S13: Collecting data on taking the elevator downward, in response to the wearer taking the elevator downward, performing pressure collection operations; at this time, the pressure-sensitive parts 3 in each shoe body 1 collect the foot support conditions, and each pressure-sensitive part 3 retains the minimum and maximum values ​​measured, and the processor 21 calculates the floating range of each pressure-sensitive part 3 as X3, that is, the maximum value measured by each pressure-sensitive part 3 minus the minimum value measured by each pressure-sensitive part 3, and records the floating range X3 of each pressure-sensitive part 3 and saves it in the storage 22.

[0047] S14: Collecting the state data of the moving flat road surface. In response to the wearer being in the walking state on the flat road surface, the pressure collection operation is performed. The pressure-sensitive component 3 records the data of the foot from the suspended state to the grounded state. At this time, the pressure-sensitive component 3 in each shoe body 1 collects the foot support conditions. Each pressure-sensitive component 3 will retain the minimum and maximum values ​​measured, and the processor 21 calculates the floating range of each pressure-sensitive component 3 as X4, that is, the maximum value measured by each pressure-sensitive component 3 minus the minimum value measured by each pressure-sensitive component 3, and records the floating range X4 of each pressure-sensitive component 3 and saves it in the storage 22.

[0048] Moreover, when the wearer is walking, the processor 21 also needs to process the triggering sequence of all the pressure sensing parts 3 of the same shoe body 1, and save the triggering sequence data into the storage 22. Through the triggering sequence of the pressure sensing parts 3, the footsteps of the wearer in the natural walking state can be preliminarily fed back.

[0049] At the same time, the processor 21 also needs to record the interval time T1, T2, T3, etc. of the adjacent triggering pressure-sensitive parts 3, and the change stroke of each interval time is T1. mix -T1 max ,T2 mix -T2 max ,T3 mix -T3 max ... and record the above data in the storage. The trigger interval data can be combined with the trigger sequence data to improve the accuracy of the footstep posture data. In order to reduce the false triggering of the sounder, the data collection needs to leave a collection margin. After all, the wearer cannot walk at the same step frequency and speed for a long time, so it is necessary to collect the wearer's natural walking step frequency and speed as a reference.

[0050] S15: Collect stair climbing status data, and perform pressure collection operations in response to the wearer climbing the stairs; the pressure-sensitive component records data on the foot's transition from a suspended state to a landed state; at this time, the pressure-sensitive components in each shoe collect the foot support conditions, and each pressure-sensitive component retains the minimum and maximum measured values, and uses the processor to calculate the floating range of each pressure-sensitive component as X5, that is, the maximum value measured by each pressure-sensitive component minus the minimum value measured by each pressure-sensitive component, and records the floating range X5 of each pressure-sensitive component and saves it in the storage device.

[0051] Moreover, when the wearer is walking up the stairs, the processor needs to process the triggering sequence of all the pressure-sensitive parts on the same shoe body and save the triggering sequence data into the storage. Through the triggering sequence of the pressure-sensitive parts, the wearer's footsteps in the natural walking state can be initially fed back.

[0052] At the same time, the processor also needs to record the interval time T4, T5, T6... of the adjacent trigger pressure sensing parts, and the change stroke of each interval time is T4. mix -T4 max ,T5 mix -T5 max ,T6 mix -T6 max ... and record the above data in the storage. The trigger interval data can be combined with the trigger sequence data to improve the accuracy of the footstep posture data. In order to reduce the false triggering of the sounder, the data collection needs to leave a collection margin. After all, the wearer cannot walk at the same step frequency and speed for a long time, so it is necessary to collect the wearer's natural walking step frequency and speed as a reference.

[0053] S16: Collect stair descent status data, and perform pressure collection operations in response to the wearer going down the stairs; the pressure-sensitive component records data on the foot's transition from a suspended state to a grounded state; at this time, the pressure-sensitive components in each shoe collect the foot support conditions, and each pressure-sensitive component retains the minimum and maximum measured values, and uses the processor to calculate the floating range of each pressure-sensitive component as X6, that is, the maximum value measured by each pressure-sensitive component minus the minimum value measured by each pressure-sensitive component, and records the floating range X6 of each pressure-sensitive component and saves it in the storage device.

[0054] Moreover, when the wearer is walking down the stairs, the processor needs to process the triggering sequence of all the pressure-sensitive parts on the same shoe body and save the triggering sequence data into the storage. Through the triggering sequence of the pressure-sensitive parts, the wearer's footsteps in the natural walking state can be initially fed back.

[0055] At the same time, the processor also needs to record the interval time T7, T8, T9... of the adjacent trigger pressure sensing parts, and the change stroke of each interval time is T7. mix -T7 max ,T8 mix -T8 max ,T9 mix -T9 max ... and record the above data in the storage. The trigger interval data can be combined with the trigger sequence data to improve the accuracy of the footstep posture data. In order to reduce the false triggering of the sounder, the data collection needs to leave a collection margin. After all, the wearer cannot walk at the same step frequency and speed for a long time, so it is necessary to collect the wearer's natural walking step frequency and speed as a reference.

[0056] Since the pressure sensing shoes are only for the elderly, exercise or climbing up and down hills are not part of their daily living habits, and relevant data collection or judgment is not performed in this direction.

[0057] S2: Determination, the wearer's state needs to be determined, such as standing state and moving state; the standing state can be further divided into simple standing state or elevator state, and the moving state can be further divided into walking state and ladder climbing state; then the data is compared in the corresponding different states, and an alarm is issued to prevent falls.

[0058] S21: Determine the static state. In response to no change in the pedometer and no obvious change in the air pressure sensor, it is preliminarily determined that the wearer is in a static state. The floating range of the value change of the single pressure-sensitive component is set to X0. If X0 is greater than X1, that is, the wearer's body center of gravity is unstable and the pressure value in the local area of ​​the foot is tilted, the processor sends an electrical signal to the sounder and causes the generator to sound an alarm.

[0059] S22: Determine the elevator status. In response to the pedometer sensor not changing and the air pressure sensor changing significantly, determine that the wearer is in the elevator status. And determine whether the elevator is in the ascending or descending status according to the rise and fall of the air pressure sensor value. If the floating range of the value change of a single pressure sensing element is X0, X0 can be compared with X2, X3 according to the ascending and descending status of the wearer; if X0 is greater than X2 or X3; the center of gravity of the wearer's body is unstable, that is, the processor sends an electrical signal to the sounder, and the generator sounds an alarm.

[0060] S23: Determine the moving state.
