Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is described in further detail.
Refer to Fig. 1, this figure is depicted as the structured flowchart of an air conditioner controlling device of the present invention embodiment.As shown in Figure 1, the control device of this embodiment includes optical sensor 11, optical signal processing unit 12 and control unit 13.Wherein, optical sensor 11, for detecting the luminance signal of indoor environment residing for air-conditioner, can adopt optical sensor of the prior art to realize.Optical signal processing unit 12 is electrically connected with optical sensor 11, for receiving luminance signal that optical sensor 11 exports and processing this luminance signal, obtains natural daylight intensity and intensity of light and exports.Natural daylight intensity is obtained respectively and intensity of light can adopt prior art to realize from luminance signal, such as, according to: utilize natural daylight light intensity value to change mitigation in time, in the trend of gradually changing, and light light intensity change lofty, change irregular feature in time, utilize the luminance signal in multiple adjacent cells time to obtain nature luminous intensity and intensity of light respectively.And control unit 13 performs the operational mode corresponding with the natural daylight intensity that optical signal processing unit 12 exports and intensity of light for controlling air-conditioner.Specifically, control unit 13 by controlling the compressor, blower fan etc. of air-conditioner according to natural daylight intensity and intensity of light, to reach comfortable, energy-conservation control effects.Control procedure can with reference to the description of figure 2 and Fig. 3 method flow more specifically.
The control device of this embodiment is applied in air-conditioner, such as, can optical sensor 11 be arranged on air conditioner casing, and optical signal processing unit 12 and control unit 13 are arranged on air-conditioner computer board, air-conditioner is controlled, realizes air-conditioner to the comfort conditioning of indoor temperature and the energy consumption reducing air-conditioner.
Refer to Fig. 2, the figure shows the method flow that the control device based on Fig. 1 embodiment controls air-conditioner.
As shown in Figure 2, this embodiment comprises the steps: the flow process that air-conditioner controls
Step 21: by the luminance signal of indoor environment residing for light sensors air-conditioner.
Optical sensor is arranged on air-conditioner, such as, be arranged on air-conditioner indoor unit shell, can the luminance signal of indoor environment residing for perception air-conditioner, and the luminance signal of perception is outputted to corresponding processing unit.For indoor, luminance signal includes two parts, and a part is natural daylight signal, and another part is non-natural optical signal, is also light signal.Therefore, luminance signal may comprise independent natural daylight signal or light signal, also may be the mixed signal that both are formed.
Step 22: process the luminance signal that step 21 detects, obtains natural daylight intensity and intensity of light.
The luminance signal that step 21 detects is processed, isolates natural daylight and light, and calculate natural daylight intensity and intensity of light respectively.The realization of this step can adopt prior art, then this is not construed as limiting and specifically sets forth.
Step 23: control air-conditioner and perform the operational mode corresponding with natural daylight intensity and intensity of light.
Due in the environment of different natural daylight, different light, the requirement of human body to comfortableness is different, this just need air-conditioner to perform requirement that different patterns meets human body comfort to greatest extent.Meanwhile, air-conditioner runs under rational pattern, can play the consumption avoiding the unnecessary energy, the object reducing energy consumption.Thus, in this embodiment, to light sensors to luminance signal carry out analyzing and processing, obtain natural daylight intensity and intensity of light, environmental aspect is judged more accurately, and realize controlling more accurately air-conditioner according to the judgement of environmental aspect, improve the energy consumption of the comfortable of using air-condition device and reduction air-conditioner, reach comfortable, energy-conservation effect.
The concrete processing procedure that step 23 controls the air-conditioner execution operational mode corresponding with natural daylight intensity and intensity of light can adopt Fig. 3 to realize.
As shown in Figure 3, the figure shows the specific implementation flow chart of step 23 in Fig. 2 embodiment.Specifically, following process control air-conditioner can be adopted to perform the operational mode corresponding with natural daylight intensity and intensity of light:
Step 231: judge whether intensity of light is greater than light threshold value.If so, step 234 is performed; Otherwise, perform step 232.
Light threshold value is the setting value stored in memory, the size of this threshold value can be that to dispatch from the factory be the empirical value drawn by market survey, laboratory great many of experiments by air-conditioner control technology personnel, also can be the numerical value obtained the relational learning between indoor light and user's set model by preset self-learning algorithm, this embodiment logarithm value size and acquisition methods be not construed as limiting.Obtain intensity of light from luminance signal after, itself and light threshold value are made comparisons, the size of both judgements, and perform different process according to judged result.
Step 232: when step 231 judges that intensity of light is not more than light threshold value, judges whether natural daylight intensity is greater than natural daylight first threshold.If so, step 234 is performed; Otherwise, perform step 233.
In this embodiment, be provided with two natural daylight threshold values, be respectively natural daylight first threshold and natural daylight Second Threshold, and natural daylight Second Threshold be greater than natural daylight first threshold.Similar with light threshold value, natural daylight first threshold and natural daylight Second Threshold are all the setting values stored in memory, the size of threshold value can be that to dispatch from the factory be the empirical value drawn by market survey, laboratory great many of experiments by air-conditioner control technology personnel, also can be the numerical value obtained the relational learning between natural daylight intensity and user's set model by preset self-learning algorithm, this embodiment logarithm value size and acquisition methods be not construed as limiting.Obtain natural daylight intensity from luminance signal after, first itself and natural daylight first threshold, also namely less threshold value are made comparisons, the size of both judgements, and perform different process according to judged result.
Step 233: if natural daylight intensity is not more than natural daylight first threshold and intensity of light is not more than light threshold value, represents that indoor natural daylight is strong, light is also strong, in the case, shows that indoor human body is in resting state, as sleep state.Now, human body is in inactive state substantially, not high to the refrigerating/heating requirement of strength of air-conditioner, for saving energy consumption, avoid human body to cross cold or overheated and cause uncomfortable simultaneously, control air-conditioner and be automatically transferred to sleep pattern by present mode of operation and run.
Preferably, when controlling air-conditioner and entering sleep pattern, the display lamp controlled on air-conditioner is in OFF state, avoids annoying users to have a rest, also energy-conservation further.
Step 234: if step 232 judges that natural daylight intensity is greater than natural daylight first threshold, or step 231 judges that intensity of light is greater than light threshold value, then judge whether natural daylight intensity is less than natural daylight Second Threshold further.If so, step 235 is performed; Otherwise, perform step 236.
Step 235: the present mode of operation controlling air-conditioner is constant.
Be not more than light threshold value at intensity of light, natural daylight intensity being when being greater than natural daylight first threshold and being less than natural daylight Second Threshold, represent that it is also completely not black, now, human body is also in active state, but natural daylight intensity is not very strong.Therefore, control air-conditioner and run according to user's set model, also namely keep present mode of operation constant, to meet the refrigerating/heating demand of user.
In addition, when intensity of light is greater than light threshold value, turn on light in indoor, represents that user does not have a rest, be also in active state.If natural daylight intensity is less than natural daylight Second Threshold, illustrate that natural daylight intensity is not very strong.In the case, also control air-conditioner and run according to user's set model, also namely keep present mode of operation constant, to meet the refrigerating/heating demand of user.
Step 235: if step 234 judges that natural daylight intensity is not less than natural daylight Second Threshold, also i.e. the greater, show that now natural daylight intensity is comparatively large, generally refers to the time period that before midday, sunlight is stronger, then control air-conditioner and perform and force cold or weak heating.
Specifically, regardless of the size of intensity of light, as long as natural daylight intensity is more than or equal to larger natural daylight Second Threshold, if air-conditioner present mode of operation is refrigeration, owing to being in the sunlight stronger moment, indoor temperature is higher, then perform pressure cold, to improve thermoregulator comfortableness; And if air-conditioner present mode of operation is for heating, owing to being in the sunlight stronger moment, indoor temperature is higher, then perform weak heating, and is not affecting the prerequisite decline low energy consumption of user's comfortableness.Wherein, control air-conditioner operation and force cold being specially: obtain the compressor frequency that air-conditioner calculates according to current refrigeration pattern, as the frequency that PID arithmetic draws, control compressor and run with the frequency of the compressor frequency calculated higher than this.And control air-conditioner and run weak heating and be specially: obtain the compressor frequency that calculates according to current heating mode of air-conditioner, as the frequency that PID arithmetic draws, control compressor and run with the frequency of the compressor frequency calculated lower than this.
By adopting the concrete control strategy of Fig. 3 embodiment, comfortable, the energy-efficient performance of air-conditioner can be improved further.
Above embodiment only in order to technical scheme of the present invention to be described, but not is limited; Although with reference to previous embodiment to invention has been detailed description, for the person of ordinary skill of the art, still can modify to the technical scheme described in previous embodiment, or equivalent replacement is carried out to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of the present invention's technical scheme required for protection.
