In order to illustrate technical solutions according to the invention, illustrated below by specific embodiment.
Fig. 1 shows the realization flow of foot method for monitoring state provided in an embodiment of the present invention, and details are as follows:
S101:In preset each acquisition time, control is acquired positioned at the temperature sensor of the socks body of the first socks To the first temperature sequence, and Synchronization Control is located at the temperature sensor of the socks body of the second socks and collects second temperature sequence; The temperature sensor of the socks body for being located at the first socks is distinguished with the temperature sensor of socks body for being located at the second socks Corresponding human foot position mirror symmetry.
In the embodiment of the present invention, socks presence in pairs, respectively above-mentioned first socks and the second socks.Each socks Multiple location points are previously provided on socks body, and a temperature sensor is respectively fixed on the point of each position.Due to each It puts a little corresponding with a human body foot position, thus may be such that user pulls on one's stockings the period of the day from 11 p.m. to 1 a.m, each temperature sensor energy on socks body Enough it is attached at a preset human foot position.The location point being present on socks body for example can be with the big toe of human body, The corresponding location point of the foot positions such as ball of foot, arch of foot, heel or Jing Qian arteria dorsalis pedises area with human body, arteria peronea The corresponding location point in blood supplies region such as preceding perforating branches area, lateral plantar artery area.
The location point that same human foot position is corresponded on two socks is mirrored into symmetrically in distribution so that two socks Son can be respectively suitable for two feet of user.
In the embodiment of the present invention, temperature sensor refers to that temperature can be experienced and is converted into the sensor of usable output signal. Illustratively, temperature sensor can be realized by thermistor, and resistance can increase with temperature and be reduced.Therefore, root According to preset resistance and the correspondence of temperature value, it will can in real time measure obtained resistance and be converted to temperature data.
At each moment, according to the control instruction received, control respectively is distributed in the temperature sensor on two socks The temperature value of the preset human foot position of synchronous acquisition.In preset acquisition duration, each temperature sensor will be adopted persistently Collection obtains multiple temperature values.Each temperature value that each temperature sensor is collected is stored in a temperature sequence.No The temperature value that synthermal sensor is collected is stored in different temperature sequences, so that each temperature sensor and a temperature Degree series correspond to.
In the embodiment of the present invention, for being located at the first socks and the second socks, and corresponding human foot position respectively Symmetrical two temperature sensors are mirrored into, corresponding temperature sequence is the first temperature sequence and second temperature sequence Row.
S102:First temperature sequence and the second temperature sequence are parsed, determines abnormal temperature value therein.
For each temperature sequence, dissection process is carried out to each temperature value therein, to identify the temperature sequence In whether there is abnormal temperature value.If occurs abnormal temperature value in temperature sequence, then it represents that the corresponding temperature of the temperature sequence passes Sensor is practically in discrete state, i.e. the time point at the time point of acquisition abnormity temperature value with preset human foot position Socks be not bonded completely with the foot area.Therefore, in the temperature sequence, abnormal data value is rejected, is only protected Stay in other times collected do not occur abnormal temperature value.
Illustratively, the identification process of abnormal temperature value for example can be:If the temperature value in temperature sequence is not belonging to pre- If the warm reference interval of human body foot, then the temperature value is determined as abnormal temperature value.
Illustratively, the identification process of abnormal temperature value for example can be:If any temperature value in temperature sequence with it is same The collected ambient temperature value of one time point institute is identical, and the difference between the temperature value of temperature value acquisition time adjacent thereto Value is more than predetermined threshold value, then the temperature value is determined as abnormal temperature value.
S103:Each abnormal temperature value is replaced with into its corresponding warm predicted value of foot, first temperature that obtains that treated Degree series and treated second temperature sequence;Wherein, the warm predicted value of the foot represents the temperature sensing of acquisition abnormity temperature value Device is with being expected collected foot temperature value in the state of human foot skin contact.
In the embodiment of the present invention, since abnormal temperature value is not the temperature value for human body foot position, it is therefore desirable to adopting At the time of collecting the abnormal temperature value, the actual temperature value of human foot position is estimated, to determine that abnormal temperature value institute is right The warm predicted value of foot answered.It, will be each after calculating the warm predicted value of the corresponding foot of each abnormal temperature value in each temperature sequence Abnormal temperature value replaces with its corresponding warm predicted value of foot, with the temperature sequence that obtains that treated.It is found that treated temperature sequence In row, no longer include abnormal temperature value.
As one embodiment of the present of invention, as shown in Fig. 2, above-mentioned replace with its correspondence by each abnormal temperature value Foot warm predicted value the step of, specifically include:
S201:For acquiring the temperature sensor of the abnormal temperature value, the temperature sensor is obtained in the exception temperature The collected historical data of institute on angle value corresponding acquisition time.
In temperature sequence before treatment, abnormal temperature value is identified, and obtain each corresponding to each abnormal temperature value A acquisition time, and then determine the temperature sensor of acquisition abnormity temperature value institute is collected on each acquisition time goes through History data.
For example, if the acquisition time of a certain abnormal temperature value A is 12:30am, the temperature for acquiring abnormal temperature value A pass Sensor is temperature sensor a, then obtains temperature sensor a 12:The collected historical data of 30am institutes, i.e. the previous day 12: 30am, 12 before two days:12 before 30am or more days:The collected temperature value of 30am institutes.Particularly, when only reading default recently Historical data in length.
S202:The historical data is averaging, is the corresponding foot of the abnormal temperature value by the output of obtained average value Warm predicted value.
In the temperature sensor for determining acquisition abnormity temperature value, institute is collected on each acquisition time multiple goes through After history temperature value, the average value of each historical temperature value is calculated.It is pre- that the average value is determined as the corresponding foot temperature of abnormal temperature value Measured value.
For example, in the examples described above, abnormal temperature value A is 16 degree, acquisition time 12:30am acquires the exception Nearest three days of the temperature sensor of temperature value A is 12:The collected historical temperature value of 30am institutes is 27 degree, 29 degree and 28 degree, 27 degree, 29 degree and 28 degree of average value is then determined as the warm predicted value of the corresponding foots of abnormal temperature value A.
In the embodiment of the present invention, since temperature sensor is in the collected each historical temperature value of institute of same acquisition time Comparatively stablize, thus by by temperature sensor institute collected historical data average value output be abnormal temperature value pair The warm predicted value of foot answered, ensure that can be close in the reality of user for replacing the warm predicted value of foot of abnormal temperature value Border foot temperature value, so as to improve the accuracy of the warm DATA REASONING of the foot of temperature sensor.
As one embodiment of the present of invention, as shown in figure 3, in above-mentioned S103, each abnormal temperature value is replaced For its corresponding warm predicted value of foot, also may be accomplished by:
S301:Reject all abnormal temperature values in the corresponding temperature sequence of the abnormal temperature value, and by remaining temperature Angle value carries out multiple process of fitting treatment, obtains N number of fitting function.
In each temperature sequence before treatment, each abnormal temperature value that will identify that carries out rejecting processing so that temperature It is only collected in each preset acquisition time institute comprising temperature sensor and be not recognized as abnormal temperature in degree series The temperature value of value.
For each temperature sequence, based on the acquisition time corresponding to each temperature value remaining in temperature sequence, lead to Preset N number of fitting algorithm is crossed, each temperature value remaining in temperature sequence is fitted, can obtain N number of fitting function.Intend It closes and represents, change the undetermined coefficient in function by adjusting preset Temperature-time so that function institute in Each point in time Corresponding functional value can be minimum with the difference of each temperature value remaining in temperature sequence.Temperature-time variation function is treated Determine after coefficient determines to get to a fitting function.It is worthwhile that fitting algorithm includes but not limited to linear fit algorithm, Nonlinear Quasi Method and piecewise fitting algorithm algorithm etc..
S302:Acquisition time corresponding to the abnormal temperature value is inputted into N number of fitting function, it is described to export respectively The corresponding N number of warm match value of foot of abnormal temperature value.
S303:The average value of N number of warm match value of foot is determined as the warm predicted value of the corresponding foot of the abnormal temperature value; Wherein, the N is the integer more than 1.
For each abnormal temperature value rejected in temperature sequence, the acquisition time of the abnormal temperature value is determined, and The acquisition time is inputted into above-mentioned N number of fitting function respectively.Due to the warm match value of the exportable foot of each fitting function, because And N number of exportable N number of warm match value of foot of fitting function.The average value of the warm match value of N number of foot is determined into the abnormal temperature value Foot temperature predicted value.
In the embodiment of the present invention, by carrying out repeatedly effectively fitting to non-abnormal temperature value, based on adopting for abnormal temperature value Collection time point calculates the warm match value of foot, and the average value output of multiple foot temperature match values is warm for the corresponding foot of abnormal temperature value Predicted value so that the warm predicted value of foot acquired can more accurately reflect the actual temperature of user's foot.
S104:In the first temperature sequence after treatment and treated second temperature sequence, if corresponding same acquisition The temperature value at time point meets preset condition simultaneously, then sends out foot status early warning information, the foot status early warning packet Include medical prompt message and health care tutorial message.
After above-mentioned S102 and S103 first temperature sequence that obtains that treated and second temperature sequence, each Acquisition time can obtain the second temperature in first temperature value and the second temperature sequence in the first temperature sequence Value.
If the first temperature value and the difference of second temperature value are more than predetermined threshold value, then it represents that may using the user of the socks With foot ulcers risk, therefore warning information is sent out, reinforcement pair is checked or instruct the user how so that user to be prompted to go to a doctor in time The foot health-care of itself.Health care tutorial message includes diet guide information, exercise guidance information and everyday general purpose tutorial message Deng.
Illustratively, since the common reason of foot ulcers risk is that user blood glucose amount is higher or foot damages, Therefore foot status early warning information can be suggest user eat what reduce blood glucose food, suitable for do it is what kind of movement with And what kind of insole etc. should be used.
In the embodiment of the present invention, by being solved to the collected each temperature value of temperature sensor institute for being located at socks body Analysis, can recognize that abnormal temperature value therein;Its corresponding foot is replaced with by the abnormal temperature value for recognizing each Warm predicted value improves the accuracy rate of sufficient temperature measurement so that foot status early warning information be based on temperature sensor with human body Pedal skin contact in the state of institute collected foot temperature value and send out, thus ensure that the full extent early warning letter Breath is caused by the foot ulcers risk of user, thus reduces the rate of false alarm of monitoring and early warning information;In life During into foot status early warning information, by sending out medical prompt message and health care tutorial message so that user, which recognizes, to be worked as How whether the preceding moment should carry out daily individual health care and need to go to a doctor in time, which thereby enhance the effective of information alert Property.
