Detailed ways

In the following description, for purposes of illustration and description However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the invention.

First, the socks mentioned in the embodiments of the present invention will be explained. The sock involved in the embodiment of the present invention is made of a flexible fabric, and a plurality of temperature sensors are embedded on a side of the flexible fabric that is not close to the human skin. Each temperature sensor is fixed at a different point of the sock so that after the user puts on the sock, each temperature sensor can be indirectly attached to each position of the user's foot through the flexible fabric.

In a specific implementation, for example, for each sock, a wire and a control module are disposed on an outer surface thereof. The control module internally includes a circuit board and a battery for powering the circuit board and various temperature sensors electrically connected to the circuit board. The control module is fixed to the sock of the sock and is located on the side not close to the human skin. As another specific implementation, the control module and its welded portion are wrapped with waterproof glue, and the outer side of the wire is also wrapped with waterproof glue, so that the socks can be washed.

In various embodiments of the invention, the control module can communicate with the remote terminal device via a wired, wireless or Bluetooth connection. The terminal device is a smart terminal having a display screen, such as a mobile phone, a tablet, a notebook computer, a computer, and the like. The terminal device internally runs an application client, and based on the application client, data exchange with the control module can be implemented. For example, the control module can transmit the collected foot temperature data to the remote terminal device through the wireless network, so that the user can view his own foot temperature data in real time. Moreover, the control module can also receive an instruction issued by the terminal device, and control the temperature sensor to perform an operation according to the instruction.

In order to explain the technical solution described in the present invention, the following description will be made by way of specific embodiments.

FIG. 1 is a flowchart showing an implementation process of a foot state monitoring method according to an embodiment of the present invention, which is described in detail as follows:

S101: At each preset collection time point, the temperature sensor that controls the sock body of the first sock acquires a first temperature sequence, and synchronously controls a temperature sensor located in the sock body of the second sock to obtain a second temperature sequence; The temperature sensor of the sock body located in the first sock is mirror-symmetrical to the position of the human foot corresponding to the temperature sensor of the sock body of the second sock.

In the embodiment of the present invention, the socks are double-shaped, which are the first socks and the second socks, respectively. A plurality of position points are preset on the sock body of each sock, and a temperature sensor is respectively fixed at each position point. Since each position point corresponds to a human foot position, each temperature sensor on the body can be attached to a predetermined human foot position when the user puts on the socks. The position point existing on the body of the sock may be, for example, a position corresponding to the position of the foot of the human body such as the big toe, the forefoot, the arch of the foot, the heel, or the like, or may be the area of the dorsal artery of the forefoot of the human body and the front of the radial artery. A point corresponding to the blood supply area such as the perforating area and the lateral plantar area.

The positions of the two socks corresponding to the position of the same human foot are mirror-symmetrical in distribution, so that the two socks can be respectively applied to the two feet of the user.

In the embodiment of the invention, the temperature sensor refers to a sensor that can sense the temperature and convert it into an available output signal. Illustratively, the temperature sensor can be implemented by a thermistor whose resistance value decreases as the temperature increases. Therefore, according to the preset correspondence between the resistance value and the temperature value, the resistance value measured in real time can be converted into temperature data.

At each moment, according to the received control command, the temperature sensors distributed on the two socks are respectively controlled to synchronously collect the temperature values of the preset human foot positions. Each temperature sensor will continuously acquire multiple temperature values during the preset acquisition time. Each temperature value collected by each temperature sensor is stored in a temperature sequence. The temperature values collected by the different temperature sensors are stored in different temperature sequences, thereby making each temperature sensor correspond to a temperature sequence.

In the embodiment of the present invention, for the two temperature sensors respectively located in the first sock and the second sock, and the corresponding human foot positions are mirror-symmetrical, the respective temperature sequences are the first temperature sequence and the second temperature sequence.

S102: Parse the first temperature sequence and the second temperature sequence to determine an abnormal temperature value therein.

For each temperature sequence, each of the temperature values is parsed to identify whether an abnormal temperature value is present in the temperature sequence. If an abnormal temperature value occurs in the temperature sequence, it indicates that the temperature sensor corresponding to the temperature sequence is actually separated from the preset human foot position at the time when the abnormal temperature value is collected, that is, the socks at the time point do not have the foot. The area is completely fit. Therefore, in this temperature sequence, the abnormal data values are eliminated, and only the temperature values acquired at other time points without occurrence of abnormalities are retained.

Exemplarily, the process of identifying the abnormal temperature value may be, for example, determining the temperature value as an abnormal temperature value if the temperature value in the temperature sequence does not belong to the preset human foot temperature reference interval.

Exemplarily, the process of identifying the abnormal temperature value may be, for example, if any temperature value in the temperature sequence is the same as the ambient temperature value collected at the same time point, and the temperature value is the temperature value of the adjacent collection time point. The difference between the temperatures is greater than the preset threshold, and the temperature value is determined as the abnormal temperature value.

S103: Substituting each of the abnormal temperature values with a corresponding predicted foot temperature value, and obtaining a processed first temperature sequence and a processed second temperature sequence; wherein the predicted foot temperature value indicates an abnormal temperature value is collected. The temperature sensor predicts the value of the foot temperature collected in contact with the skin of the human foot.

In the embodiment of the present invention, since the abnormal temperature value is not the temperature value of the human foot position, it is necessary to estimate the actual temperature value of the human foot position at the time of collecting the abnormal temperature value to determine the abnormal temperature value. The predicted foot temperature. In each temperature sequence, after calculating the predicted foot temperature value corresponding to each abnormal temperature value, each abnormal temperature value is replaced with its corresponding predicted foot temperature value to obtain a processed temperature sequence. It can be seen that the abnormal temperature value is no longer included in the processed temperature sequence.

As an embodiment of the present invention, as shown in FIG. 2, the step of replacing each of the abnormal temperature values with the corresponding predicted foot temperature value includes:

S201: For a temperature sensor that collects the abnormal temperature value, obtain historical data collected by the temperature sensor at an acquisition time point corresponding to the abnormal temperature value.

In the temperature sequence before processing, the abnormal temperature value is identified, and each collection time point corresponding to each abnormal temperature value is obtained, thereby determining the historical data collected by the temperature sensor collecting the abnormal temperature value at each collection time point. .

For example, if the collection time point of an abnormal temperature value A is 12:30 am, and the temperature sensor that collects the abnormal temperature value A is the temperature sensor a, the historical data collected by the temperature sensor a at 12:30 am is acquired. Temperature values collected at 12:30 am one day, 12:30 am two days ago, or 12:30 am two days ago. In particular, only historical data within the most recent preset duration is read.

S202: The historical data is averaged, and the obtained average value is output as a full-foot temperature predicted value corresponding to the abnormal temperature value.

After determining a plurality of historical temperature values collected by the temperature sensor collecting the abnormal temperature value at each acquisition time point, the average value of each historical temperature value is calculated. The average value is determined as a predicted foot temperature value corresponding to the abnormal temperature value.

For example, in the above example, the abnormal temperature value A is 16 degrees, and the acquisition time point is 12:30 am. The temperature sensor that collects the abnormal temperature value A collects a historical temperature value of 27 degrees at 12:30 am in the last three days. At 29 degrees and 28 degrees, the average values of 27 degrees, 29 degrees, and 28 degrees are determined as the predicted foot temperature values corresponding to the abnormal temperature value A.

In the embodiment of the present invention, since the historical temperature values collected by the temperature sensor at the same acquisition time point are relatively stable, the average value of the historical data collected by the temperature sensor is output as the foot temperature prediction corresponding to the abnormal temperature value. The value ensures that the predicted foot temperature value for replacing the abnormal temperature value can be as close as possible to the actual foot temperature value of the user, thereby improving the accuracy of the temperature sensor data measurement of the temperature sensor.

As an embodiment of the present invention, as shown in FIG. 3, in the above S103, replacing each of the abnormal temperature values with the corresponding predicted foot temperature values may also be implemented by:

S301: Excluding all abnormal temperature values in the temperature sequence corresponding to the abnormal temperature value, and performing multiple fitting processes on the remaining temperature values to obtain N fitting functions.

In each temperature sequence before processing, each identified abnormal temperature value is culled, so that the temperature sequence only includes the temperature sensor collected at each preset acquisition time point and is not recognized as an abnormal temperature value. Temperature value.

For each temperature sequence, based on the acquisition time points corresponding to the remaining temperature values in the temperature sequence, the preset N fitting algorithms are used to fit the remaining temperature values in the temperature sequence, so that N Combined function. The fitting indicates that by adjusting the undetermined coefficient in the preset temperature-time variation function, the function value corresponding to the function at each time point can be minimized from the remaining temperature values in the temperature sequence. After the undetermined coefficient of the temperature-time variation function is determined, a fitting function is obtained. The fitting algorithms include, but are not limited to, a linear fitting algorithm, a nonlinear fitting algorithm, a piecewise fitting algorithm algorithm, and the like.

S302: Input an acquisition time point corresponding to the abnormal temperature value into N fitting functions to respectively output N foot temperature fitting values corresponding to the abnormal temperature value.

S303: Determine an average value of the N full-foot temperature fitting values as a full-foot temperature predicted value corresponding to the abnormal temperature value; wherein the N is an integer greater than 1.

For each abnormal temperature value that is eliminated in the temperature sequence, the acquisition time point of the abnormal temperature value is determined, and the acquisition time points are respectively input to the N fitting functions. Since each fitting function can output a full-foot fitting value, the N fitting functions can output N full-foot fitting values. The average of the N full-foot temperature fit values is used to determine a full-foot temperature predictor of the abnormal temperature value.

In the embodiment of the present invention, the foot temperature fitting value is calculated based on the abnormal time value of the abnormal temperature value, and the average value of the plurality of foot temperature fitting values is output as the abnormality. The predicted value of the temperature value corresponds to the full-temperature predicted value, so that the obtained full-scale predicted value of the foot temperature can more accurately reflect the actual temperature of the user's foot.

S104: In the processed first temperature sequence and the processed second temperature sequence, if the temperature value corresponding to the same collection time point satisfies the preset condition at the same time, the foot state warning information is sent, and the foot state warning information is sent. Includes information on presentations and health guidance information.

After the processed first temperature sequence and the second temperature sequence are obtained by the foregoing S102 and S103, at each acquisition time point, a first temperature value in the first temperature sequence and a second temperature in the second temperature sequence may be acquired. value.

If the difference between the first temperature value and the second temperature value is greater than a preset threshold, it indicates that the user who uses the socks may have a risk of foot ulcer, so an early warning message is issued to prompt the user to check the medical treatment in time or to guide the user how to strengthen the self. Foot care. Health guidance information includes dietary guidance information, exercise guidance information, and daily wear guidance information.

Illustratively, since the general cause of the risk of foot ulcers is that the blood glucose level of the user is high or the foot is damaged, the foot state warning information may be a food that advises the user to eat what lowers blood sugar, what type of exercise is appropriate, and should be used. What type of insole, etc.

As an embodiment of the present invention, as shown in FIG. 4, the foregoing S104 further includes:

S1041: In the processed first temperature sequence and the processed second temperature sequence, if the temperature values corresponding to the same collection time point simultaneously satisfy the preset condition, the pressure values of the respective preset human foot positions are collected.

In the embodiment of the present invention, in addition to the temperature sensor, a plurality of pressure sensors are disposed on the sole of the sock. The pressure sensor includes an elastomer and a strain gauge attached to the surface of the elastomer. Since the socks are made of elastic fabric, when the user puts on the socks, the weight of the user's body exerts pressure on the bottom of the sock, so that the elastic body in the pressure sensor and the resistance strain gauge attached to the surface thereof are also deformed. The resistance of the strain gauge is also changed. Therefore, by measuring the resistance value of the strain gauge, the detected pressure value at each moment can be determined according to the correspondence between the preset resistance value and the pressure value.

In the processed first temperature sequence and the processed second temperature sequence, if the temperature values corresponding to the same collection time point simultaneously satisfy the preset condition, in order to further determine the user's foot state, each pressure sensor is controlled to collect the human foot. The pressure value of the position.

S1042: Generate a first foot pressure distribution model based on the collected pressure values.

Based on the measured pressure values for each foot position, a first foot pressure distribution model can be generated.

Illustratively, a process of generating a first foot pressure distribution model is described: rendering a human foot region schematic in a terminal interface, the human foot region schematic including a plurality of foot position regions; according to a pressure sensor in a sock The fixed position points mark the pressure values measured by the respective pressure sensors in the corresponding foot position regions in the human foot region schematic diagram, and render the respective foot position regions with the pressure level color elements corresponding to the pressure values.

S1043: Acquire a human body state at a current moment, where the human body state includes a motion state and a non-motion state.

Illustratively, an acceleration sensor is provided inside the control module of the sock or inside the terminal device. The acceleration sensor is an electronic device that can measure the acceleration value in various directions. When the acceleration sensor is a three-axis accelerometer, it can measure the acceleration of the x, y, and z axes. Based on the acceleration values in each direction, it can be determined whether the socks or the terminal device is in motion. If the socks or the terminal device is in a motion state, the human body state is determined to be a motion state; if the socks or the terminal device is in a non-motion state, the human body state is determined to be a non-motion state.

Exemplarily, the state of the human body at the current moment can also be obtained by the law of the change of the pressure of the sole of the foot, as follows: for the same sole position point, each pressure value collected at the point of the sole position at each moment is determined separately. The pressure state at the point of the foot. If the pressure state continues to alternate between the first state and the second state within the preset time period, it is determined that the human body state at the current moment is the motion state; if the preset duration is within the preset duration, the pressure state continues to be the first state or continues to be the first state In the second state, it is determined that the human body state at the current moment is a non-motion state.

S1044: Acquire a second foot pressure distribution model that matches the human body state, and the second foot pressure distribution model is generated based on all historical pressure values collected in the human body state.

In the embodiment of the present invention, the foot pressure distribution model generated by the historical pressure value collected by the pressure sensor in the moving state and the foot pressure distribution model generated by the historical pressure value collected in the non-moving state are pre- The two foot pressure distribution models of the user are stored. After determining the human body state at the current time in S107, a foot pressure distribution model matching the human body state can be read and taken out, and the foot pressure distribution model is the second foot pressure distribution model. The second foot pressure distribution model is a model generated by the user without the risk of foot ulcer.

S1045: Calculate the similarity between the first foot pressure distribution model and the second foot pressure distribution model.

The similarity between the two models is determined based on the second foot pressure distribution model corresponding to the user's risk of not having a foot ulcer and the first foot pressure distribution model generated in the current state.

In the embodiment of the present invention, the calculation method of the model similarity may be implemented by using an existing image similarity algorithm, or may be implemented by using other algorithms, which is not limited herein.

For example, in the above example, the foot pressure distribution plan includes a foot position area marked with a plurality of color elements, and the second foot pressure distribution model also includes a foot position area marked with a plurality of color elements. Then, according to the color matching degree of the color element corresponding to each of the two foot regions in the two models, the color matching degree can be determined as the similarity of the foot position region. After calculating the similarity of each foot position region, the similarity between the first foot pressure distribution model and the second foot pressure distribution model can be calculated according to the preset weights corresponding to the respective foot position regions.

S1046: If the similarity is less than a preset threshold, the foot state warning information is sent.

If the similarity between the first foot pressure distribution model and the second foot pressure distribution model is less than the second predetermined threshold, the current user's foot pressure distribution and the foot pressure distribution when the user does not have the risk of foot ulcers There is a big difference, so the current user is likely to have a problem of partial compression of the foot, which may easily lead to poor blood flow, thereby increasing the risk of suffering from diabetic foot, and therefore, issuing a warning information on the foot state.

In the embodiment of the present invention, the difference between the first foot pressure distribution model and the second foot pressure distribution model at the current time is analyzed, and it is determined that the user's foot position pressure is too large, so that the user's foot pressure is abnormal. At the location point, the health care instruction information is issued, and the user is recommended to use an insole or shoe that is adapted to the characteristics of the individual's foot pressure. For example, if the user's pressure at the foot position A is too large, the user may be recommended to use the insole with the foot position A thickened to avoid the user's foot position A from being prone to wear, resulting in an increased risk of foot ulcers.

Preferably, if the first foot pressure distribution model is a foot pressure model corresponding to the user in the non-moving state, in addition to detecting the similarity between the first foot pressure distribution model and the second foot pressure distribution model, It is also possible to detect whether the pressure value corresponding to the arch region is greater than a preset threshold in the first foot pressure distribution model. If the pressure value corresponding to the arch region is greater than the preset threshold, it indicates that the user has a greater probability that the arch has collapsed. At this time, a medical reminder message is issued to prompt the user to seek medical treatment in time.

In the embodiment of the present invention, by providing a pressure sensor on the sock body, combined with the foot temperature data and the foot pressure data to further issue the foot state warning information, the monitoring of the user's foot state is enhanced, and the effectiveness of the warning is improved.

As an embodiment of the present invention, based on the above various embodiments, the manner of collecting the temperature sensor is further defined. As shown in FIG. 5, the above S101 specifically includes:

S1011: Control a pressure sensor located at the sole of the first sock or the sole of the second sock to collect a preset pressure value of the human foot position.

S1012: Determine, according to the pressure values collected at each moment, the pressure state of the preset human foot position at each moment.

In the embodiment of the present invention, two pressure amplitude intervals are preset, and each pressure amplitude interval corresponds to a pressure state.

According to the pressure value range of the pressure amplitude interval, the pressure amplitude interval to which the sole pressure value is collected at each moment is determined, and the pressure state corresponding to the pressure amplitude interval is the current pressure state.

For example, if the pressure amplitude interval corresponding to the first state is [0, b] kPa and the pressure amplitude interval corresponding to the second state is (b, c] kPa, when the current pressure value d < b , will determine the current state of the pressure state as the first state.

S1013: Increase the acquisition frequency of the temperature sensor if the pressure state continues to alternate between the first state and the second state within a preset duration.

Corresponding to the respective foot pressure values collected within the preset duration, a plurality of pressure states within the preset duration can be determined. If a plurality of first states are continuously generated, the pressure state is changed to the second state, and after the plurality of second states are continuously generated, the pressure state is changed to the first state again, and is repeatedly performed within the preset time period, and then determined to be The pressure state continues to alternate between the first state and the second state. At this time, the acquisition frequency adjustment command is issued to increase the acquisition frequency of the temperature sensor, so that each temperature sensor respectively fixed on the sock body of the two socks can perform temperature collection with the increased acquisition frequency.

If the pressure state continues for a predetermined period of time, the temperature sensor is controlled to perform the temperature acquisition set with the reduced acquisition frequency.

In the embodiment of the present invention, the pressure value of the user's sole is collected by controlling the pressure sensor, and the pressure state is determined according to the pressure value, and the user is determined to be in a walking or running state under the condition that the pressure state continuously changes. , thereby increasing the acquisition frequency of the temperature sensor. Because the human body is in a state of motion and non-exercise, the rate of change of the temperature of the foot will be different. In the state of motion, the foot is prone to sweating, and the foot temperature will rise more easily during the unit time, thus increasing the temperature. The acquisition frequency of the sensor ensures that the accuracy and efficiency of the data acquisition of the foot temperature can be improved, and the monitoring effect on the state of the foot is enhanced. In the non-exercise state, the foot temperature will be relatively stable in unit time, so by reducing the frequency of the temperature sensor acquisition, the energy consumption of the socks can be reduced.

It should be understood that the size of the sequence of the steps in the above embodiments does not imply a sequence of executions, and the order of execution of the processes should be determined by its function and internal logic, and should not be construed as limiting the implementation of the embodiments of the present invention.
