Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from 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 present invention with unnecessary detail.
First, the socks mentioned in the embodiments of the present invention will be explained. The sock is made of flexible fabric, and a plurality of temperature sensors are embedded in the side, not close to the skin of a human body, of the flexible fabric. Each temperature sensor is fixed in the different position points of socks to after making the user wear this socks, each temperature sensor can see through this flexible surface fabric, attached in each position point of user's foot indirectly.
In a specific implementation, for example, for each sock, on its outer surface, the electric wires and the control module are arranged. The control module internally comprises a circuit board and a battery, and the battery is used for supplying power to the circuit board and each temperature sensor electrically connected with the circuit board. The control module is fixed at the welt of the sock and is positioned on one side which is not close to the skin of the human body. As another specific implementation mode, the control module and the welding position thereof are wrapped with waterproof glue, and the outer side of the electric wire is also wrapped with waterproof glue, so that the sock can be washed.
In various embodiments of the present invention, the control module may communicate with a remote terminal device through a wired, wireless, or bluetooth connection. The terminal equipment is an intelligent terminal with a display screen, such as a mobile phone, a tablet, a notebook computer, a computer and the like. The terminal device runs a specific application program client inside, and data exchange with the control module can be realized based on the application program client. For example, the control module may transmit the collected foot temperature data to a remote terminal device through a wireless network, so that the user can view the foot temperature data of the user in real time. And the control module can also control the temperature sensor to execute the operation and the like according to the instruction issued by the terminal equipment.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Fig. 1 shows an implementation flow of a method for acquiring foot temperature data according to an embodiment of the present invention, which is detailed as follows:
s101: and acquiring the measurement data of the tension sensor at a preset time interval, wherein the tension sensor is fixed on the edge of the welt of the sock.
In the embodiment of the invention, the socks exist in pairs and are used in pairs. The two socks are the sock and the other sock respectively. A plurality of position points are arranged on the sock body of each sock in advance, and a temperature sensor is fixed on each position point respectively. And a tension sensor is arranged at the edge of the welt of each sock and on the side which is not close to the skin of the foot of the human body. The tension sensor comprises an elastic body and a resistance strain gauge adhered to the surface of the elastic body. Because the sock is made of the elastic fabric, when a user pulls open the sock opening, the elastic body in the tension sensor can elastically deform under the action of tension, so that the resistance strain gauge adhered to the surface of the elastic body deforms along with the elastic deformation, and the resistance value of the resistance strain gauge changes. By measuring the resistance value of the resistance strain gauge, external force can be converted into an electric signal.
For one sock, the resistance value corresponding to the tension sensor is collected according to a preset time interval, namely the measurement data of the tension sensor is obtained at the preset time interval.
S102: and analyzing the measurement data to detect the tension value of the sock at each moment.
And analyzing the measurement data obtained in real time according to the preset corresponding relation. Wherein, the corresponding relationship is the corresponding relationship between the resistance value and the tension value of the resistance strain gauge in the tension sensor. Because each resistance value corresponds to a tension value, the tension value at each moment can be determined based on the resistance value measurement data of the tension sensor acquired at each moment.
S103: and determining a tension variation extreme value in a first preset time length according to each detected tension value in the first preset time length.
In an embodiment of the present invention, the first preset time period is an average time period required by the user to complete the action of wearing the socks, for example, 5 seconds. Through the steps S101 and S102, a plurality of pulling force values can be measured within a first preset time period. Since the magnitude of each tension value may be different, the maximum tension value and the minimum tension value are determined from the plurality of tension values, and the difference between the two tension values is the extreme value of the tension variation.
When the difference value between the two tension values is determined, whether the measurement time of the maximum tension value in the first preset time length is earlier than the measurement time of the minimum tension value is judged according to the measurement time sequence of the tension values
If the measurement time of the maximum pulling force value is earlier than that of the minimum pulling force value, the change trend of the detected pulling force value in the first preset time length is shown to be changed from big to small, and therefore the pulling force change extreme value is the difference value between the maximum pulling force value and the minimum pulling force value.
If the measurement time of the maximum pulling force value is later than that of the minimum pulling force value, the change trend of the detected pulling force value in the first preset time length is changed from small to large, and therefore the pulling force change extreme value is the difference value between the minimum pulling force value and the maximum pulling force value.
S104: if the absolute value of the tension variation extreme value is greater than a preset threshold value and the tension variation extreme value is a negative value, synchronously controlling a temperature sensor fixed on the outer surface of the first sock and a temperature sensor fixed on the outer surface of the second sock to respectively acquire preset temperature values of the position of the foot of the human body; the human foot positions corresponding to the temperature sensor on the outer surface of the first sock and the temperature sensor fixed on the outer surface of the second sock are in mirror symmetry.
The preset threshold value is a tension value corresponding to the degree that the welt at least needs to be stretched under the condition that the user can wear the sock.
If the extreme value of the tension variation is the difference value between the minimum tension value and the maximum tension value, the difference value is a value less than zero, so that the extreme value of the tension variation within the first preset time length can be determined to be a negative value. In particular, when the sock is not in use, the tension value detected by the tension sensor is minimal, so the minimal tension value is zero. Under the condition that the tension variation extreme value is a negative value, if the absolute value of the tension variation extreme value is greater than a preset threshold value, the fact that the user wears the socks is determined, and therefore the socks are started to run, namely, each temperature sensor fixed on the outer surfaces of the two socks is synchronously controlled to respectively collect preset temperature values of the positions of the feet of the human body.
In the embodiment of the invention, the temperature sensor refers to a sensor which can sense the temperature and convert the temperature into a usable output signal. Illustratively, the temperature sensor may be implemented by a thermistor, which is similar to the implementation principle of the tension sensor, except that the resistance of the thermistor decreases as the temperature increases. Therefore, the resistance value obtained by real-time measurement can be converted into temperature data according to the corresponding relation between the preset resistance value and the temperature value.
In the embodiment of the invention, when any sock is started to operate, the other sock is also started to operate synchronously, so that the temperature sensors with mirror symmetry on the outer surface of the two socks can simultaneously acquire the temperature values of the mirror symmetry human foot positions. The temperature values of the human foot positions which are acquired at the same moment and are in mirror symmetry have a comparative significance and have a reference value, so that when the absolute value of the tension change extreme value of a certain sock is detected to be larger than a preset threshold value and the tension change extreme value is a negative value, the temperature sensor on the sock is controlled to start acquiring the temperature value, and besides, a clock signal of the sock is required to be sent to another sock which is used in a matched mode. At the same time, for example, at Beijing time 08:30:31AM, the temperature sensor fixed on the outer surface of the sock is controlled to acquire the preset temperature value of the position of the foot of the human body, and meanwhile, the temperature sensor fixed on the outer surface of the other matched sock can be accurately controlled to acquire the preset temperature value of the position of the foot of the human body at the Beijing time 08:30:31AM, so that the control modules on the two socks can control the temperature sensors to acquire the temperature values based on synchronous clock signals.
As an embodiment of the present invention, as shown in fig. 2, after the above S104, the method further includes:
s105: and acquiring the measurement data of the tension sensor at preset time intervals.
S106: and analyzing the obtained measurement data to detect the tension value of the sock.
S107: and if the pulling force value is detected to be zero, synchronously controlling the temperature sensor fixed on the outer surface of the sock and the temperature sensor fixed on the outer surface of the other sock to stop collecting the preset temperature value of the position of the foot of the human body.
And when the tension value at the current moment is detected each time, judging the determined tension value so as to judge whether the tension value is zero or not. If the tension value is zero, the tension variation trend of the sock opening before the moment can be determined to be changed from big to small, and the user does not wear the intelligent sock any more, so that the temperature value acquired by the temperature sensor is no longer the foot temperature data of the human body, and the monitoring value is not available, so that the temperature sensors fixed on the outer surface of the sock are controlled to stop acquiring the temperature value of the position of the foot of the human body to which the temperature sensors are attached.
In the embodiment of the invention, the tension sensor is arranged at the edge of the welt of the sock, and the tension value at each moment is detected, so that the current deformation state of the sock can be determined according to the change condition of the tension value; through analyzing each pulling force value within a preset time length, when the pulling force change extreme value is greater than a preset threshold value and the pulling force change extreme value is a negative value, the sock can be determined that the user is wearing the sock at present, so that the temperature value of the foot of the user is collected by controlling each temperature sensor on the outer surface of the sock, and the fact that the user can perform measurement of the foot temperature after manually starting the foot temperature detection equipment is no longer needed is guaranteed. Meanwhile, after the intelligent socks are started, the user can be determined not to use the socks according to the tension value as zero, and the measurement of the foot temperature data is automatically closed, so that the intelligent degree of the foot temperature data acquisition is improved. As the user can automatically acquire the foot temperature data as long as wearing the socks all the time, the all-weather foot temperature monitoring requirement of the user is met.
As an embodiment of the present invention, as shown in fig. 3, the S104 specifically includes:
s1041: if the absolute value of the tension change extreme value is greater than the preset threshold value and the tension change extreme value is a negative value, the temperature sensor fixed on the outer surface of the sock and the temperature sensor fixed on the outer surface of the other sock are synchronously controlled to acquire the preset temperature value of the position of the foot of the human body at the first acquisition frequency within the second preset time period.
When the absolute value of the tension change extreme value is greater than the preset threshold value and the tension change extreme value is a negative value, the fact that the user wears the socks is determined, therefore, in order to know the temperature of the feet of the user at the current moment as soon as possible after the user wears the socks, each temperature sensor fixed on the outer surface of the socks is controlled to collect the temperature value of the preset position of the feet of the human body at a first relatively high collection frequency. Because the temperature sensor does not start operation in the initial state, and the resistance value of the thermistor only changes along with the environmental temperature value, when the sock starts operation, the initial temperature value collected based on the temperature sensor is the environmental temperature value. After the user wears the socks, the temperature value detected by the temperature sensor is gradually increased in a short time, and finally the temperature value detected by the temperature sensor is the real temperature value of the foot of the user when the temperature value reaches a stable state.
In the embodiment of the invention, the temperature sensor is controlled to acquire the preset temperature value of the foot position of the human body at a higher acquisition frequency within the second preset time length, so that the time length required for the temperature sensor to reach the stable state from the initial state can be shortened, the temperature value displayed on the terminal interface tends to be stable as soon as possible, and the measurement efficiency of the foot temperature data is improved.
The second preset time period may be a maximum time period that the temperature sensor needs to experience when reaching the steady state from the initial state, which is obtained by statistics in advance. Preferably, the second preset time period may also be the longest time period required for the temperature sensor to reach the steady state from the initial state and within 2 minutes after reaching the steady state.
S1042: after the second preset time, synchronously controlling the temperature sensor fixed on the outer surface of the sock and the temperature sensor fixed on the outer surface of the other sock to acquire a preset temperature value of the foot position of the human body at a second acquisition frequency; wherein the first acquisition frequency is greater than the second acquisition frequency.
After the second preset time, the temperature values measured by the temperature sensors on the outer surfaces of the two socks reach a stable state, which is the real temperature value of the human foot, and the temperature of the human foot does not change greatly within a short time interval, so that each temperature sensor fixed on the outer surfaces of the two socks is synchronously controlled to acquire the preset temperature value of the position of the human foot at a relatively low second acquisition frequency, and the energy consumption of the socks can be saved.
As another embodiment of the present invention, fig. 3 shows a specific implementation flow of the method for acquiring foot temperature data S104 provided by the embodiment of the present invention, which is detailed as follows:
s1043: and if the absolute value of the tension change extreme value is greater than a preset threshold value and the tension change extreme value is a negative value, acquiring a working mode at the current moment, wherein the working mode is a motion mode or a rest mode.
In the embodiment of the invention, when the absolute value of the tension variation extreme value is greater than the preset threshold value and the tension variation extreme value is a negative value, the intelligent sock is started. The method specifically comprises the following steps: and enabling each temperature sensor fixed on the outer surface of the sock to execute operation in a working mode corresponding to the current moment. The working modes of the temperature sensor comprise a sport mode and a rest mode. The working mode corresponding to each moment can be obtained through an application program client operated by the terminal equipment, and can also be obtained according to a mode key selection instruction sent by a user on a control module of the sock.
For example, when the user is ready to run, in order to accurately control the respective temperature sensors on the outer surface of the sock to operate in a designated operation mode, the operation mode may be set to an exercise mode in the application client; or, a positioning module is arranged in the terminal device, and if the geographical position within the preset time length is detected to be continuously changed, the user is determined to be moving, so that the working mode at the current moment is determined to be the moving mode.
S1044: and if the working mode at the current moment is the motion mode, synchronously controlling the temperature sensor fixed on the outer surface of the sock and the temperature sensor fixed on the outer surface of the other sock to acquire the preset temperature value of the foot position of the human body at the first acquisition frequency.
S1045: and if the working mode at the current moment is a rest mode, synchronously controlling the temperature sensor fixed on the outer surface of the sock and the temperature sensor fixed on the outer surface of the other sock to acquire the preset temperature value of the foot position of the human body at a second acquisition frequency.
If the working mode at the current moment is detected to be the motion mode, each temperature sensor on the two socks is synchronously controlled to start to collect the temperature value of the position of the foot of the human body attached to the corresponding sock at a first relatively high collection frequency. And if the working mode at the current moment is detected to be a rest mode, synchronously controlling each temperature sensor on the two socks to start to collect the temperature value of the position of the foot of the human body attached to the corresponding sock at a relatively low second collection frequency.
In the embodiment of the invention, by acquiring the working modes of the temperature sensor at different moments, the temperature sensor can be controlled to acquire foot temperature data at the first acquisition frequency corresponding to the movement mode when a user is in a movement state; and when the user is in a rest state, controlling the temperature sensor to acquire foot temperature data at a second acquisition frequency corresponding to the rest mode. Because when the human body is in the motion state and the non-motion state, the change rate of the foot temperature can be different, under the motion state, the foot is easy to sweat, and the foot temperature is easier to rise in unit time, so that the acquisition frequency of the temperature sensor is switched, the accuracy and efficiency of the acquisition of the foot temperature data are ensured, and the monitoring effect on the foot state is enhanced. Under the rest state, the foot temperature is relatively stable in unit duration, so that the energy consumption of the intelligent socks can be reduced by reducing the acquisition frequency of the temperature sensor.
As an embodiment of the present invention, on the basis of the above embodiments, the distribution positions of the temperature sensors on the outer surface of the sock are further defined. The method comprises the following specific steps:
the outer surface of the sock and the outer surface of the other sock are respectively fixed with a plurality of temperature sensors, and the position point of each temperature sensor corresponds to each blood supply area of the foot of the human body. As shown in fig. 5, the blood supply area includes an anterior tibial dorsal artery area 1, a anterior peroneal perforator area 2, a lateral plantar artery area 3, a medial plantar artery area 4, a posterior tibial calcaneal branch area 5, a posterior tibial dorsal femoral artery area 6, and a peroneal calcaneal branch area 7.
In the embodiment of the invention, the foot of the human body is divided into different areas according to the three-dimensional blood vessel distribution of the human body, and each area has specific arterial blood supply and venous return, so the areas are called blood supply areas (angiosomes).
Since the blood supply region of the human foot includes the sole region and the lower leg region, each position point to which the temperature sensor is attached on the outer surface of the sock includes a position point corresponding to the sole region and the lower leg region.
In the embodiment of the invention, in each sock, one or more temperature sensors are respectively fixed at different positions on the outer surface of the sock, and the positions are ensured to correspond to the blood supply area of the foot of the human body, so that when a user wears the sock, each temperature sensor can be indirectly attached to each blood supply area of the foot of the human body through the flexible fabric, and the surface temperature data of each blood vessel is obtained through measurement. If the two socks corresponding to the two foot temperature values of the same blood supply area have abnormal temperature difference, the problem that blood flow is not smooth possibly occurring in blood vessels corresponding to the blood supply area can be predicted, and the high risk of causing diabetic feet is achieved.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
