Embodiment of the method
Fig. 1 is infant's temperature monitoring method process flow diagram that the inventive method embodiment provides.As shown in Figure 1, infant's temperature monitoring method, comprising:
Step S1, under infant monitoring device is operated in guardian mode, the Region dividing detected by thermal sensors is the capable N row of M M*N trellis subregions altogether, preferably, 8 row 8 are divided into by surveyed area to arrange 64 sub regions altogether, data are also passed to controller by the temperature data of each lattice of 8 row 8 row 64 sub regions of thermal sensors Real-time Collection indoor, controller reads the temperature data of 8 row 8 row 64 sub regions of thermal sensors Real-time Collection, after the temperature data opsition dependent coordinate arrangement of 64 positions, ask for temperature value R (i) and the G (i) of the high temperature of every a line and low temperature cluster centre, R (i) and G (i) is obtained by K-Means clustering algorithm.Concrete matlab algorithm is as follows:
(1) example is established the initial value (cluster centre value) of the temperature minimum value m1 of 8*8 trellis subregion and maximal value m2 as R (i) and G (i);
(2) in kth time iteration, for the i-th row (i is from the first row to the 8th row) any one sample, it is asked for the distance of high temperature cluster centre value and the distance of low temperature cluster centre value;
(3) this sample is grouped into the class at the shortest place, center of distance.Concrete, if the difference that a certain temperature deducts high temperature cluster centre value is less than the difference that a certain temperature deducts low temperature cluster centre value, then this temperature value is assigned in high temperature one class; If the difference that a certain temperature deducts high temperature cluster centre value is greater than the difference that a certain temperature deducts low temperature cluster centre value, then this temperature value is assigned in low temperature one class;
(4) the high temperature cluster value in high temperature one class and the low temperature cluster value in low temperature one class is upgraded respectively.Concrete, all sample summations in high temperature one class are averaged, as next high temperature cluster centre value; Sample summation in all low temperature one classes is averaged, as next low temperature cluster centre value;
(5) for the new high temperature cluster centre value after renewal in (4) and low temperature cluster centre value, the high temperature cluster centre value asked for last iteration respectively and low temperature cluster centre value are made comparisons, if after utilizing the process of iteration of (2) (3) (4) to upgrade, high temperature cluster centre value and low temperature cluster centre value remain unchanged (objective function converges), then iteration terminates, last is taken turns high temperature cluster centre value that iteration asks for as high temperature cluster centre R (i), last is taken turns low temperature cluster centre value that iteration asks for as low temperature cluster centre G (i), otherwise continuation iteration.Above process carries out maximum 200 iteration, the convergence in the mean finally asked for.
Wherein, 1≤i≤M; Afterwards again by (R (i)-G (i)) * C1 (i) and (R (i)-G (i)) * C2 (i) as the upper and lower threshold value of temperature, wherein, C1 (i), C2 (i) are the coefficients determining the i-th row detection sensitivity; Perform step S11 afterwards.
