As a kind of embodiment, shown in Figure 2, step S500 comprises the steps:
S510, judges whether the second floor temperature difference T1 preset in heating duration t2 is all less than or equal to the default floor temperature difference.
S511, is if so, then optimized process according to described indoor temperature difference T2 to indoor temperature difference correction value C and floor material restriction factor m.
S511, if not, is not then optimized process to indoor temperature difference correction value C and floor material restriction factor m.
After heating duration t1 is preset in floor heating heating first, second presets heating duration t2 (time-count cycle) comes into effect, within a time-count cycle (namely continue second presets heating duration t2), floor detecting element detects the floor temperature difference of the multiple sense cycle of continuous print, judge whether the second all floors temperature difference preset in heating duration t2 continued all is less than or equal to the default floor temperature difference, if preset floor temperature difference T1 in heating duration t2 continue second to have and be greater than the default floor temperature difference, explanatorily plate temperature is unstable, floor temperature is unstable, indoor environment temperature change greatly, now process is not optimized to indoor temperature difference correction value C and floor material restriction factor m, continue to detect the floor temperature difference and the indoor temperature difference, if preset floor temperature difference T1 in heating duration t2 continue second be all less than the default floor temperature difference, floor temperature is stablized, indoor environment is relatively stable, according to indoor temperature difference T2, process is optimized to indoor temperature difference correction value C and floor material restriction factor m, make indoor environment more comfortable, and more energy-conservation.
In order to more clearly explain the implementation process of this embodiment, being described, what deserves to be explained is below in conjunction with concrete parameter, the parameter in embodiment only for explaining this embodiment, and is not used in this embodiment of restriction:
If the second default heating duration t2 is 2min, sense cycle is 40s, after heating duration 30min is preset in floor heating heating first, floor detecting element detects floor surface temperature at once, a floor surface temperature is detected again after sense cycle 40s, calculate the floor temperature difference T11 of floor surface temperature in 40s, judge whether Δ T11 is less than or equal to the default floor temperature difference, after 40s, detect floor surface temperature again, calculate floor temperature difference T12 in 40s, judge whether Δ T12 is less than or equal to the default floor temperature difference, the rest may be inferred, detect a floor surface temperature every 40s later, calculate floor temperature difference T1n in 40s, and judge whether Δ T1n is less than or equal to the default floor temperature difference.When judging that in continuous print 3 40s (namely second presetting heating duration 2min), the floor temperature difference is all less than or equal to the default floor temperature difference, then judge that floor temperature difference T1 satisfies condition, then carry out the step according to indoor temperature difference T2, described indoor temperature difference correction value C and described floor material restriction factor m being optimized to process.Wherein: second presets heating duration t2 timing from detecting the time point of floor surface temperature at every turn.
As a kind of embodiment, step S511 comprises the steps:
When indoor temperature difference T2≤-2 DEG C, indoor temperature difference correction value C is optimized for C=-Δ T2*1.2, floor material restriction factor m is optimized for m=-(Δ T2+2)/10+1.15.
As the indoor temperature difference-2 DEG C of < Δ T2<0 DEG C, indoor temperature difference correction value C is optimized for C=-Δ T2*0.8, floor material restriction factor m is optimized for m=-(Δ T2+2)/10*0.9+1.15.
As the indoor temperature difference 0 DEG C≤Δ T2<1 DEG C, indoor temperature difference correction value C is optimized for C=0, floor material restriction factor m is optimized for m=1.15.
When indoor temperature difference T2 >=1 DEG C, indoor temperature difference correction value C is optimized for C=-Δ T2*1.5, floor material restriction factor m is optimized for m=-(Δ T2-1)/10+1.15.
When above-described embodiment is optimized process, comprise the optimization of indoor temperature difference correction value C and the optimization to flooring board matter restriction factor m.When wherein optimizing indoor temperature difference correction value C, its optimal value is divided into four kinds of situations, is respectively when Δ T2≤-2 DEG C, is optimized for C=-Δ T2*1.2; As-2 DEG C of < Δ T2<0 DEG C, be optimized for C=-Δ T2*0.8; As 0 DEG C≤Δ T2<1 DEG C, be optimized for C=0; When Δ T2>=1 DEG C, be optimized for C=-Δ T2*1.5; After optimization, according to formula T=T
c* the supply water temperature after m+ (H-60) * T1-d*T2+C calculation optimization, and control floor heating by the supply water temperature heating after optimization, make indoor environment more comfortable, and more energy-conservation.After this suboptimization, when meeting the condition of the above-mentioned floor temperature difference, detect once the indoor temperature difference every preset time t 4, and upgrade once indoor temperature difference correction value C according to indoor temperature difference T2, real-time update supply water temperature.At the end of this floor heating heating, preserve the last indoor temperature difference correction value C upgraded, when upper once floor heating start heating, directly carry out assignment with the indoor temperature difference correction value C of the last renewal of preserving, calculate supply water temperature, reduce the optimization time.
When user inputs floor heating parameter, floor material have selected " other ", then when starting shooting first, floor material is defaulted as " timber floor ", comprehensively other parameters, and calculate the supply water temperature heated first, when heating first, indoor temperature difference correction value is defaulted as 0.After heating duration is preset in heating first, when judging that the second floor temperature difference T1 preset in heating duration continued all is less than or equal to the default floor temperature difference, flooring board matter restriction factor m is optimized, its optimal value is divided into situation in four, be respectively when Δ T2≤-2 DEG C, be optimized for m=-(Δ T2+2)/10+1.15; As-2 DEG C of < Δ T2<0 DEG C, be optimized for m=-(Δ T2+2)/10*0.9+1.15; As 0 DEG C≤Δ T2<1 DEG C, be optimized for m=1.15; When Δ T2 >=1 DEG C, be optimized for m=-(Δ T2-1)/10+1.15; Optimally sheet material matter restriction factor m, makes supply water temperature supply water by the temperature meeting most this floor material, will floor be caused because temperature rise is too fast to ftracture, and also the heat time will be made long because temperature rise is crossed slow.After floor material restriction factor m optimizes, according to formula T=T
c* the supply water temperature after m+ (H-60) * T1-d*T2+C calculation optimization, and control floor heating by the supply water temperature heating after optimization, make indoor environment temperature more comfortable, and more energy-conservation.After this suboptimization, when meeting the condition of the above-mentioned floor temperature difference, the indoor temperature difference is detected once every preset time t 4, and upgrade a floor material restriction factor m according to the indoor temperature difference, so that real-time update supply water temperature, supply water temperature is supplied water with the temperature of the most coincidently sheet material matter, in heating process, ensures that floor material is not damaged all the time, and make indoor environment temperature comfortable, simultaneously more energy-conservation.At the end of floor heating heats first, preserve the last floor material restriction factor upgraded, as floor material restriction factor (indoor floor is generally infrequently changed) on this new floor, reduce the optimization time.
