Apparently, the described embodiments are only some of the embodiments of the present utility model, but not all of them. Based on the embodiments in the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the embodiments of the present utility model.

It is to be understood that the data so used are interchangeable under appropriate circumstances such that the embodiments of the application described herein can be practiced in sequences other than those illustrated herein.

The technical solutions provided by the various embodiments of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Fig. 1 is a structural schematic diagram of embodiment one of the fall warning intelligent insole based on multi-sensor analysis of the present invention, as shown in Fig. The fall monitoring device on the insole body, wherein the fall monitoring device may include a first angle sensor 10 , a first acceleration sensor 11 , a pressure sensor 12 , a first processor 13 and a first alarm 14 .

In the embodiment of the present invention, the first processor 13 may be electrically connected to the first angle sensor 10 , the first acceleration sensor 11 , the pressure sensor 12 and the first alarm 14 respectively. The first angle sensor 10 is used to obtain the angle parameter of the insole main body and the horizontal plane, and sends the angle parameter to the first processor 13, and the first acceleration sensor 11 is used to obtain the first acceleration value of the insole main body, and sends the angle parameter to the first processor 13 Send the first acceleration value, and the pressure sensor 12 is used to obtain the first pressure value that the insole body bears, and send the first pressure value to the first processor 13, and the first processor 13 is used for according to the angle parameter and the inclination angle threshold range, Obtain the first fall probability value, obtain the second fall probability value according to the first acceleration value and the threshold value range of the first acceleration value, obtain the third fall probability value according to the first pressure value and the pressure threshold value, and obtain the third fall probability value according to the first fall probability value , the second fall probability value and the third fall probability value to obtain the first comprehensive fall probability value of the wearer, and according to the first comprehensive fall probability value and the preset alarm threshold value, control the first alarm 14 to send an alarm signal or not to send Alarm.

For example, the wearer of the smart insole with fall warning based on multi-sensor analysis puts the smart insole with fall warning based on multi-sensor analysis in the shoe. obtained from each sensor in . For example, the first angle sensor 10 can be but not limited to a gyroscope, which is generally used to measure the rotational angular velocity of an object, and then obtain the angle parameter of the measured object. In the embodiment of the present invention, the first angle sensor 10 can be used to obtain The angle parameter between the main body of the insole and the horizontal plane is further obtained to obtain the standing angle parameter of the wearer, and sent to the first processor 13 . The utility model embodiment preferably adopts two first angle sensors 10, wherein one first angle sensor 10 can measure the wearer's front and rear standing angle parameters, and the other first angle sensor 10 can measure the wearer's lateral standing angle parameters. In practical application, the model of the first angle sensor 10 may be but not limited to ENC-03MB sensor.

In a specific implementation process, the first acceleration sensor 11 can measure the acceleration produced by the gravitational effect of the earth or the movement of the object, so if the main body of the insole generates acceleration, it can be obtained by the first acceleration sensor 11 and sent to the first processing Device 13. When the first angle sensor 10 adopts the ENC-03MB sensor, considering the mutual compatibility between the signals, the embodiment of the present utility model can adopt the acceleration sensor produced by Freescale. The acceleration sensor MMA8452 of this series adopts semiconductor surface micromachining and integrated circuit technology, and the sensor is small in size and light in weight. Since the accelerometer is used together with the gyroscope, it can better detect the wearer's activity patterns and various walking movements.

The first pressure sensor 12 in the embodiment of the utility model can be made of elastic element and resistance strain gauge, when elastic element feels physical quantity, its surface produces strain, the resistance value of the resistance strain gauge pasted on the surface of elastic element will follow with The strain of the elastic element changes accordingly. By measuring the resistance value change of the resistance strain gauge, it can be used to measure various parameters such as displacement acceleration, force, moment, and pressure. In this new embodiment, it is preferred to obtain the first pressure value of the insole main body, and the first pressure value sent to the first processor 13.

In practical applications, the first processor 13 may be implemented by using but not limited to a single-chip microcomputer, for example, a 51-series single-chip microcomputer STC89C52 may be used. STC89C52 is a low-voltage, high-performance COMOS8 microprocessor with 8K bytes of flashing programmable erasable read-only memory 16. The device is fabricated using ATMEL's high-density nonvolatile memory16 fabrication technology and is compatible with the industry-standard MCS-51 instruction set and output pins.

Specifically, based on actual experience, the corresponding tilt angle threshold range when the wearer falls, the corresponding first acceleration value threshold range when the wearer falls, and the corresponding pressure threshold when the wearer falls can be preset in the first processor 13, And set different weights to the angle of inclination threshold range, the first acceleration value threshold range and the pressure threshold respectively, after the first processor 13 receives the angle parameter sent by the first angle sensor 10, the first processor 13 can according to the angle parameter and the tilt angle threshold range to obtain the first fall probability value. For example, the wearer's foot is close to the horizontal state before falling, but it is usually close to the vertical state after the fall, so a threshold range of inclination angle can be set, and multiple regions are divided for the threshold range of inclination angle from small to large, and each region corresponds to a Probability value, the first fall probability value can be obtained according to the area to which the angle parameter belongs.

Similarly, after the first processor 13 receives the first acceleration value sent by the first acceleration sensor 11 , it can obtain the second fall probability value according to the first acceleration value and the first acceleration value threshold range. For example, when the wearer is still or walking normally before a fall, the fall warning smart insole based on multi-sensor analysis does not accelerate significantly and is relatively stable, but when the wearer falls or falls, it is in a natural physiological reaction and violent shaking phenomenon. Therefore, a first acceleration value threshold range can be set, and the first acceleration value threshold range is divided into multiple regions from small to large, each region corresponds to a probability value, and the second fall can be obtained according to the region to which the first acceleration value belongs. probability value.

Similarly, after the first processor 13 receives the first pressure value sent by the first pressure sensor 12, it can obtain the third fall probability value according to the first pressure value and the pressure threshold. For example, the pressure on the wearer before the fall is usually the body weight, and the weight loss after the fall is far less than the body weight. Therefore, a pressure threshold may be set, and a third fall probability value may be obtained according to the first pressure value and the pressure threshold.

In a specific implementation process, the smart insole for fall warning based on multi-sensor analysis in the embodiment of the present invention can give an alarm according to the first fall probability threshold, the second fall probability threshold or the third fall probability threshold, but in order to accurately To determine whether the wearer has fallen, in the smart insole for fall warning based on multi-sensor analysis in the embodiment of the present invention, the first processor 13 can be based on the first fall probability value, the second fall probability value, the third fall probability value, and the respective The corresponding weight value is used to obtain the first comprehensive fall probability value of the wearer, thereby making the obtained fall probability more accurate.

In a specific implementation process, a preset alarm threshold is also stored in the processor, and the first processor 13 can control the first alarm 14 to send an alarm signal or not according to the first integrated fall probability value and the preset alarm threshold. Send an alarm signal. For example, the alarm threshold may include but not limited to a first alarm threshold and a second alarm threshold, wherein the first alarm threshold is smaller than the second alarm threshold. The first processor 13 is used to control the first alarm device 14 not to send an alarm signal if the first comprehensive fall probability value is less than or equal to the first alarm threshold; if the first comprehensive fall probability value is greater than the first alarm threshold and less than the second The alarm threshold, according to the received indication signal, controls the first alarm 14 to send an alarm signal or not to send an alarm signal; if the first comprehensive fall probability value is greater than or equal to the second alarm threshold, the first alarm 14 is controlled to send an alarm signal; wherein , the indication signal is an indication signal sent after the wearer artificially determines whether the wearer has fallen.

For example, the alarm in the embodiment of the utility model can use but not limited to a buzzer and a light emitting diode (Light Emitting Diode, LED) to alarm, and the alarm level can be divided into but not limited to 3 levels. Red, yellow and green LEDs can be used to distinguish. In the embodiment of the present invention, the first alarm threshold can be 60%, and the second alarm threshold can be 80%. When the first comprehensive probability value is less than or equal to 60%, the buzzer does not send an alarm signal, and the green light is on; when the first When the comprehensive probability value is greater than 60% and less than 80%, the indicator signal can be sent after the wearer is determined to be artificially determined, and the buzzer can be controlled to send out an alarm signal or not, and the yellow light is on. If the wearer falls, it will send an alarm signal to the alarm, and the alarm will send out an alarm signal. If it is artificially determined that the wearer has not fallen, it will send a non-alarm signal to the alarm, and the alarm will not send out an alarm signal; When the comprehensive probability value is greater than or equal to 80%, the buzzer will alarm and the red light will be on.

In a specific implementation process, when the first processor 13 determines that the wearer has fallen, the first alarm 14 is triggered to send out a flashing alarm signal and/or a beeping alarm signal. Among them, the flash alarm signal is the most commonly used alarm method. In the single-chip application system, a timing program is added to the program of the control indicator light, and the indicator light is alternately lit and extinguished according to a certain time interval. The beeping alarm signal adopts a single-frequency tone alarm, and its pronunciation element adopts a voltage buzzer. When a 3-15V DC working voltage is applied to the two pins of the buzzer, a buzzing vibration of about 3KHZ can be generated. The piezoelectric buzzer has simple structure and low power consumption, and is more suitable for application in single-chip microcomputer systems.

For example, when the angle parameter of the insole body is perpendicular to the horizontal plane, a higher first fall probability value can be obtained, but the first acceleration value of the insole body has undergone a large change, which can obtain a higher second fall probability value value, the first pressure value borne by the insole body is 0, a higher third fall probability value can be obtained, and then the obtained first comprehensive fall probability value is greater than 80%, and the wearer can be determined to fall at this time. Other conditions are similar to this implementation mechanism, and will not be illustrated here one by one.

It should be noted that in the smart insole for fall warning based on multi-sensor analysis in the embodiment of the present invention, only the first angle sensor 10, the first acceleration sensor and the first pressure sensor 12 are taken as examples to describe the technical solution of the embodiment of the present invention. However, in the actual application process, other types of sensors can also be provided according to actual needs, and their working principles are similar to those of the above-mentioned sensors, and will not be repeated here.

The fall warning intelligent insole based on multi-sensor analysis in the embodiment of the utility model, through the insole main body and the fall monitoring device arranged on the insole main body, and the first angle sensor 10, the first acceleration sensor 11, Pressure sensor 12, first processor 13 and first alarm 14, after first processor 13 is electrically connected with first angle sensor 10, first acceleration sensor 11, pressure sensor 12 and first alarm 14 respectively, by The first angle sensor 10 obtains the angle parameter of the shoe-pad main body and the horizontal plane, and sends the angle parameter to the first processor 13, obtains the first acceleration value of the shoe-pad body by the first acceleration sensor 11, and sends the first acceleration value to the first processor 13. Acceleration value; the pressure sensor 12 obtains the first pressure value that the insole body bears, and sends the first pressure value to the first processor 13; and then makes the first processor 13 obtain the first fall according to the angle parameter and the inclination angle threshold range Probability value, according to the first acceleration value and the threshold range of the first acceleration value, the second fall probability value is obtained, according to the first pressure value and the pressure threshold value, the third fall probability value is obtained, and according to the first fall probability value, the second fall probability value The probability value and the third fall probability value obtain the first comprehensive fall probability value of the wearer, and according to the first comprehensive fall probability value and the preset alarm threshold value, control the first alarm 14 to send an alarm signal or not to send an alarm signal to realize It collects the body sensor parameters of the wearer in many ways, so as to give an accurate alarm. The fall warning smart insole based on multi-sensor analysis in the embodiment of the utility model can place the fall warning smart insole based on multi-sensor analysis in any shoe of the wearer, which has low cost, is easy to wear, and can accurately monitor The status of the wearer is used to alarm, which has high reliability.

Further, in the above-mentioned embodiments, since the wearer may lie flat with shoes on, raise his legs, kick his legs, jump up and down, etc., it may cause false alarms from the fall monitoring device. Therefore, the first processing in the embodiment of the present invention The feature data set of the non-fall state is also set in the device 13, wherein the feature data set of the non-fall state includes the non-fall feature data of the angle parameter, the non-fall feature data of the first acceleration value and the non-fall feature data of the first pressure value. data. The first processor 13 is also used to detect whether the angle parameter, the first acceleration value and the first pressure value all belong to the feature data set of the non-fall state, and when the angle parameter, the first acceleration value and the first pressure value belong to the non-fall state When the feature data set is set, the first alarm device 14 is controlled not to send an alarm signal.

For example, the technical solutions of the embodiments of the present invention will be described by taking the wearer wearing shoes and lying down as an example. Multiple wearers can be selected as samples to collect the angle parameters when lying flat, as the non-fall characteristic data of the angle parameters; the acceleration value of the main body of the insole when lying flat is collected as the non-fall characteristic data of the first acceleration value, and the flat The pressure value of the main body of the insole when lying down, the non-fall feature number of the first pressure value is used as the non-fall feature data of the first pressure value, so that when the wearer lies flat, the first comprehensive fall probability value obtained is greater than 80%, but if The angle parameter, the first acceleration value and the first pressure value belong to the feature data set of the non-fall state, indicating that the wearer is in a lying state, and the first alarm 14 is controlled not to send out an alarm signal. In order to judge whether the wearer is in a fall state more accurately, it is possible to detect whether the acceleration of the insole body changes significantly when the angle parameter of the insole body belongs to the non-fall characteristic data of the angle parameter. Lying state.

Figure 2 is a schematic structural view of Embodiment 2 of the fall warning intelligent insole based on multi-sensor analysis of the present invention, as shown in Figure 2, the fall monitoring device in the fall warning intelligent insole based on multi-sensor analysis of the utility model embodiment On the basis of the embodiment shown in FIG. 1 , a first communication device 15 may be further included. The first communication device 15 is electrically connected to the first processor 13, and the first processor 13 is also used to send the first comprehensive fall probability value to the target terminal through the communication module, so that the wearer's guardian can check the status of the wearer at any time.

In an actual application process, the target terminal can be the wearer's own terminal, or a terminal authorized around the wearer, which is defined as the first terminal in the embodiment of the utility model, and can also be the terminal of the wearer's guardian. In the new embodiment, it is defined as the second terminal. Because the wearer's guardian may not be around the wearer, and due to the popularity of the current terminal, and the implementation process of the fall warning smart insole based on multi-sensor analysis and the second communication is compared with the fall warning smart insole based on multi-sensor analysis. The communication implementation process of the first terminal 2 is more complicated and the cost is higher, so the embodiment of the utility model preferably uses the first terminal as the target terminal, and then sends the wearer's status to the second terminal through the first terminal, so that the wearer The wearer's guardian can keep track of the wearer's status at any time.

For example, taking the wearer's own terminal as an example, the first communication device 15 and the first terminal can be connected by means of but not limited to infrared connection, bluetooth connection, etc. Whether the person falls or not, the principle is the same as the judgment principle of the processor on the fall warning smart insole based on multi-sensor analysis. For details, please refer to the relevant records above. When the first terminal can send the judgment result to the second terminal, or the guardian can actively obtain the status of the wearer through the second terminal. For example, a first cycle can be set in the first terminal, and the status of the wearer can be sent to the second terminal according to the first cycle, or a second cycle can be set in the second terminal, and according to the set second cycle, The status of the wearer is acquired actively from the second terminal.

In practical applications, if the wearer is in a falling state, in order to enable the guardian to know the situation in time, when the wearer's terminal determines that the wearer has fallen, it can actively send the wearer's state to the second terminal.

In an actual application process, in the embodiment of the utility model, the first processor 13 can send the angle parameter, the first acceleration value and the first pressure value to the target terminal through the first communication device 15, so that the guardian can know The specific information of the wearer, or the first comprehensive fall probability value obtained by the target terminal according to the angle parameter, the first acceleration value and the first pressure value, the realization principle is the same as that of the processor, please refer to the above related records for details, in This will not be repeated here.

In order to prevent the first communication device 15 from being unable to communicate with the target terminal in a special situation, as shown in FIG. 2 , the fall monitoring device according to the embodiment of the present invention may further include a memory 16 . The memory 16 is electrically connected with the first angle sensor 10, the first acceleration sensor 11, the pressure sensor 12 and the first processor 13 respectively, and the memory 16 is used to store the angle parameter, the first acceleration value, the first pressure value and the first comprehensive fall probability value. So that after the first communication device 15 establishes communication with the target terminal, the angle parameter, the first acceleration value, the first pressure value and the first comprehensive fall probability value are sent to the target terminal, and it is convenient for subsequent viewing of the wearer's detailed body sensor parameter.

Figure 3 is a structural schematic diagram of Embodiment 1 of a fall monitoring system of the present invention. A fall warning smart insole 1, wherein the first terminal 2 is carried by the wearer of the fall warning smart insole 1 based on multi-sensor analysis.

For example, under normal circumstances, the wearer's state can be judged through the fall warning smart insole 1 based on multi-sensor analysis, but in order to further improve the accuracy of judgment, the embodiment of the utility model introduces a terminal fall judgment program. The second acceleration sensor 21 of the first terminal 2 can provide accelerations in three directions of X, Y, and Z, while the second angle sensor 22 can provide angular velocities in three directions when the first terminal 2 reverses.

The wearer's fall is caused by the loss of balance of the body.
