Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Fig. 1 shows the realization flow of the air-conditioner room temp. control method that the embodiment of the present invention provides, and for convenience of explanation, illustrate only the part relevant to the embodiment of the present invention, details are as follows:
In step sl, the Temperature Distribution of the interior space is detected in real time, and obtain the mean temperature of the interior space.
Concrete, step S1 comprises the following steps:
S11. the temperature of each locus in the interior space is detected in real time;
S12. data processing is carried out to obtain the mean temperature of the interior space to the temperature of each detected locus.
Wherein, for above-mentioned steps S11, its specifically: based on infrared thermal imaging technique, infrared image detection is carried out to the interior space, and obtains the temperature of each locus in the interior space according to the Temperature Distribution in detected infrared image.
For above-mentioned steps S12, it is specially: carry out mean value computation to obtain the mean temperature of the interior space to the temperature of each detected locus; Namely to the computing that the temperature of each locus is averaged, and using the mean temperature of operation result as the interior space.
In an alternative embodiment of the invention, above-mentioned steps S12 specifically comprises the following steps:
S121. from the temperature of each detected locus, multiple locus temperature is extracted with sampling mode;
S122. mean value computation is carried out to obtain the mean temperature of the interior space to extracted multiple locus temperature.
Wherein, for the above-mentioned step extracting multiple locus temperature with sampling mode from the temperature of each detected locus, it is specifically: the infrared image corresponding with the interior space detected is divided into multiple area of space, and from each area of space, extract the temperature of a locus, the multiple locus temperature equal with the quantity of multiple area of space can be obtained thus.Such as, by the infrared image corresponding with the interior space detected according to 10 × 10 array dot matrix way be divided into 100 area of space, and extract the temperature of a locus from each area of space, thus 100 locus temperature can be obtained.
Therefore, after extracting multiple locus temperature by above-mentioned sampling mode, then the workload of operation that the plurality of locus temperature carries out mean value computation is obviously reduced, be conducive to improving operational speed.
In order to the degree of accuracy of the mean temperature making the obtained interior space is higher, in other embodiments of the present invention, above-mentioned steps S12 also can be specially: in the temperature of each detected locus, carries out mean value computation to obtain the mean temperature of the interior space to the temperature of each locus except constant temperature object region.
In addition, be that the degree of accuracy of the mean temperature in order to make the obtained interior space is higher equally, for above-mentioned step S121, multiple locus temperature wherein can be the temperature of the multiple locus except constant temperature object region.
It should be noted that herein, for above-mentioned constant temperature object, mainly refer in daily life, in the interior space, carry out movable people or animal (as dog, cat).Temperature due to constant temperature object is constant, so when carrying out temperature detection to each locus of the interior space, constant temperature object region can not be included in the computing reference scope of mean temperature, can be that obtained mean temperature is more accurate like this, also more can reflect the actual temperature situation of the interior space.
In step s 2, when the mean temperature of the interior space is not equal to target temperature, if air-conditioner is in refrigeration mode, then blow in the region that control air-conditioner is greater than target temperature according to target temperature to temperature in the interior space; If air-conditioner is in heating mode, then blow in the region that control air-conditioner is less than target temperature according to target temperature to temperature in the interior space.
Wherein, target temperature refers to that user makes temperature setting operation to air-conditioner and the temperature of outlet air of air conditioner pre-set.By step S2, when air-conditioner is in refrigeration mode, blow in the region that air-conditioner is greater than target temperature according to target temperature to temperature in the interior space, to reduce the temperature of areas of higher temperature, thus makes the Temperature Distribution of the interior space be tending towards even; In like manner, when air-conditioner is in heating mode, blow in the region that air-conditioner is less than target temperature according to target temperature to temperature in the interior space, to promote the temperature of temperature lower region, and then makes the Temperature Distribution of the interior space be tending towards even.
In addition, as shown in Figure 2, further comprising the steps of after step S1:
S3., when the mean temperature of the interior space equals target temperature, air-conditioner is controlled out-of-blast.
For step S3, be in fact exactly uniformly in situation in the Temperature Distribution of the interior space, just can control air-conditioner and stop regulating indoor temperature, to provide the comparatively comfortable room temperature environment of an activation for user.
In sum, in embodiments of the present invention, by detecting in real time the Temperature Distribution of the interior space, and obtain the mean temperature of the interior space, then when this mean temperature is not equal to target temperature, if air-conditioner is in refrigeration mode, then blow in the region that control air-conditioner is greater than target temperature according to target temperature to temperature in the interior space; If air-conditioner is in heating mode, blow in the region that then control air-conditioner is less than target temperature according to target temperature to temperature in the interior space, thus can under refrigerating/heating pattern to the interior space in temperature not yet reach target temperature region realize freeze more targetedly or heat, to make the mean temperature of the whole interior space reach target temperature set by user, and then the Temperature Distribution of the interior space is kept evenly.
Based on above-mentioned air-conditioner room temp. control method, the embodiment of the present invention additionally provides a kind of air conditioner chamber temperature control system, and as shown in Figure 3, it comprises:
