Specifically, above controller 111a is used for:

It is monitored using temperature-detecting device 117 indoor with the presence or absence of mobile heat source；

Temperature-detecting device 117 is by taking infrared probe as an example, and infrared probe is to indoor carry out infrared scan, when the heat detected When source, temperature and the position of heat source are recorded, and records the number of heat source of entire scanning process.When second of scanning is completed, note The temperature of second of scanning heat source of record and position, compare temperature, position and the quantity of heat source first record and second of record, When number of heat source is equal, temperature close, and when the difference of position, judge indoor there is mobile heat source.Specifically steps are as follows,

Firstly, detecting the Current Temperatures of indoor airflow using the temperature-detecting device 117 on air-conditioning；

When the Current Temperatures of heat source reach preset temperature, adopted according still further to position of the preset sample frequency to heat source Collection；I.e. only when the temperature of heat source reaches preset temperature, which is just included in heat source sum by controller, and records the heat The temperature in source and position.Different biology, calorific value are different, the calorific value of the total calorific value of people than general pet and atom It is big, therefore, most bioturbation can be excluded by the way that heat source preset temperature is arranged, be conducive to improve controller judgement Accuracy.It is, of course, also possible to compare by thermal imaging with pre-set image, qualified heat source is judged whether there is in movement.Specifically Ground, temperature-detecting device 117 can temperature according to detected heat source and position, generate heat corresponding with the heat source shape Image thermal image is compared with the default thermal image of storage in the air conditioner, when the thermal image and preset thermal map of heat source As when it fails to match, even if the temperature of the heat source reaches preset temperature, controller still excludes the heat source.

Then, current heat source position collected and current acquisition time are closed at least one heat source position of acquisition into Row compares, and judges indoor with the presence or absence of mobile heat source.

The position for comparing satisfactory heat source, when for the position of acquisition and second of the acquisition for the first time of same heat source When the difference of position, judge that the heat source moves indoors, at this point, opening the image collecting device on air conditioner.

According to the people in the image monitoring room of image collecting device 112a acquisition with the presence or absence of movement；

As the indoor people that there is movement, control image collecting device 112a carries out indoor figure according to preset frequency curve The acquisition of picture, the preset frequency curve is the corresponding relationship of image-sampling frequency and time, and the preset frequency is bent In line, the time is longer, and corresponding image-sampling frequency is lower；

When it fails to match for face characteristic obtained and preset face characteristic, control warning device 113a output alarm Information.

In the present embodiment, above controller 111a settable safety monitoring mode, user can be by being arranged on remote controler Function button selection enters or exits the mode.Certainly, in order to avoid user forgets to operate, the embodiment of the present invention can also be realized Automatic monitoring.In one example, corresponding monitoring can be set by analyzing the use habit of user or according to the setting of user Time.Such as using week as the period, Monday 9:00~18:00 carries out safety monitoring；Working day 9:00~17:00 carries out safety monitoring Etc..Or unrestricted choice monitoring period.Whether in another example, can use has in indoor infrared detector detecting chamber People, if detect it is indoor nobody when, automatically into the safety monitoring mode；If detecting indoor someone, and determine the people's Face characteristic and preset face characteristic successful match, then automatically exit from the safety monitoring mode.

Into after safety monitoring mode, controller 111a will control image collecting device 112a and carry out Image Acquisition, with prison It surveys indoor with the presence or absence of mobile people.The people of the movement may be other objects, for example, people dressed up it is animal-shaped etc.. Erroneous judgement, this hair are caused in the humanoid photosensitive visual field for resting on image collecting device 112a such as clothes textures of family in order to prevent Bright embodiment is monitored mobile people, i.e., is monitored to the people of indoor moving.When monitoring indoor someone, and this is artificial Stationary state is then not processed or reduces image-sampling frequency.When monitoring indoor someone, and the artificial moving condition, then Control image collecting device 112a carries out the crawl of off-the-air picture in the way of first high frequency again low frequency.

As shown in figure 3, said frequencies curve is the corresponding relationship of time and sample frequency, and the time is longer, sampling frequency Rate is lower.Control by this way will be used to capture figure.In the present embodiment, highest sample frequency is to adopt every 0.5 second Collect 1 frame, minimum sample frequency is every 5 seconds 1 frames of acquisition.Certainly, which may be other forms, such as Fig. 4 institute Show, minimum sample frequency is reduced to by highest sample frequency staged in the frequency curve.

The sample frequency that image collecting device 112a is exported according to controller 111a carries out the acquisition of off-the-air picture, and by institute The image of acquisition returns to controller 111a.Controller 111a calls image Processing Interface 114a, carries out to acquired image Graphics process, such as gray proces, illumination compensation etc..Meanwhile controller 111a also calls image Processing Interface to being adopted The image of collection carries out the extraction of face characteristic.After extracting face characteristic, controller 111a will also transfer images match interface 115a, The face characteristic of extraction is matched with preset face characteristic, obtains matching result.When it fails to match, alarm signal is exported Breath；When successful match, can be not processed, reduce image-sampling frequency, or exit safety monitoring mode etc..It can manage Solution, above-mentioned image procossing interface 114a and images match interface 115a can be set in controller 111a, can also be only It erects and sets and called for controller, it is not limited here.

The embodiment of the present invention by controller 111a according to indoor monitoring situation, judge it is indoor when there is mobile people, It controls image collecting device 112a and first carries out Image Acquisition according to the form of high frequency, so as to rapidly grab human figure Picture can also accurately analyze people according to the human body image grabbed when not grabbing in order to avoid human motion is too fast and face Figure.Then it is carried out according still further to the form of low frequency, to avoid long-time high frequency progress image-capture to image collecting device The damage of 112a.Certainly, if the configuration of image collecting device 112a is high, can judgement is indoor there is mobile people when, one Directly grabbed by high frequency.In addition, also recognition of face is carried out to the image grabbed, to obtain face characteristic.The present invention is implemented Example can not only identify the face grabbed, but also can accurately grab the figure of mobile people, and be movement People face characteristic extraction and identification provide more favorable guarantee, realize indoor effective monitoring.

Above-mentioned preset face characteristic is the characteristic information registered on air-conditioning in advance.By taking face information as an example, Ke Yitong It crosses following two mode and carries out face registration:

A) subscriber station, with the relative velocity of 0.5 meter per second close to camera, passes through depth of field tune within the first eight rice of conditioned surface Whole and fuzzy going, 0.5 meter of every movement sampling is primary, the face wheel that in 90 ° of camera wide-angles camera can acquire Exterior feature reaches 80% or more area and samples three effective photograph frames, then succeeds in registration.

B) user is before camera module in 2-8 meters, when subscriber station is when camera front is motionless, if facial contour Area has 80% to be able to enter in the sensitive volume of camera, then samples three valid frame pictures automatically.

In above-mentioned face registration, unique sampling principle is taken, i.e., can only once sample a face.Therefore, in order to prevent The mistake crawl of the misrecognition of face registration and more people sampling, the embodiment of the present invention use image collecting device people collected Whether face contour area has 80% to enter in the sensitive volume of camera.In addition, the air-conditioning can be registered at least in the present embodiment 16 face informations.

In the present embodiment, in the image of acquisition, there is the image of legitimate user's different location, according to the image of different location Acquisition angles and acquisition time calculate the distance of user distance air conditioner.Then turned according to different distance adjustment blowers Speed, with adjustment air-supply wind speed and air quantity.Wherein, there are many case where adjusting rotation speed of fan according to distance, for example, distance gets over strong wind Machine revolving speed is faster, slower apart from smaller rotation speed of fan；Alternatively, the bigger rotation speed of fan of distance is slower, got over apart from smaller rotation speed of fan Fastly.Certainly, in other embodiments, the relationship of rotation speed of fan and distance can be realized by setting mapping table, rotation speed of fan Relationship between distance can be linearly arranged.

Further, the controller 111a reaches the first preset quantity, and all people in face characteristic obtained Face feature and preset face characteristic export warning message when it fails to match.In the present embodiment, which is 3. The face characteristic is each characteristic information, such as eyes, forehead, eyebrow, mouth etc. of face.Image collecting device 112a according to The sample frequency of controller 111a output constantly carries out Image Acquisition, obtains multiple frame acquisitions image.It monitors indoor in the presence of shifting When dynamic people, image will be acquired to every frame and carries out face characteristic extraction, and by the face characteristic of extraction and preset face characteristic It is matched.Since face information is not easy to grab, not can guarantee every frame acquisition image can extract face characteristic, Namely face information.It judges by accident in order to prevent, setting will at least be extracted into 3 face informations in the present embodiment, when 3 faces When information is matched with preset face information, it fails to match, it is determined that there is stranger's entrance in interior, exports alarm signal Breath prompts user to have stranger's entrance.

In order to preferably prompt user or the advantageous evidence of preservation can also be together while exporting warning message Export acquired image.It is understood that the output in order to guarantee the warning message and acquired image, the present embodiment It will be independently arranged a wireless communication apparatus on air-conditioning, be exclusively used in the transmission of data during safety monitoring.

Further, the controller 111a is in face characteristic obtained and when preset face characteristic successful match, Control the acquisition that described image acquisition device 112a carries out off-the-air picture according to preset sample frequency；To acquired image into The extraction of row face characteristic, until face characteristic obtained reaches the second preset quantity.In the present embodiment, second present count Amount is 3.Controller 111a matches face characteristic obtained with preset face characteristic, if successful match, then it represents that The face characteristic registered on air-conditioning, therefore controlled image collecting device 112a and carry out indoor figure according to preset sample frequency The acquisition of picture.Then the extraction that face characteristic is carried out to the image of acquisition then stops when the face characteristic extracted reaches 3 The extraction of face characteristic.At this point, controller 111a, which can control air-conditioning, exits safety monitoring mode, it can also be according to there is no move Sample frequency when dynamic people carries out Image Acquisition.

Further, the controller 111a also controls the image collecting device 112a on air-conditioning according to preset sampling frequency The acquisition of rate progress off-the-air picture；At least frame image that the image of acquired image and the acquisition closes on acquisition is compared Compared with judging indoor with the presence or absence of mobile people.

Specifically, above controller 111a will control the image collecting device on air-conditioning when entering safety monitoring mode 112a is carried out the acquisition of off-the-air picture by preset sample frequency.The preset sample frequency is the sampling frequency of default setting Rate, and the sample frequency is greater than or equal to sample frequency minimum in the preset frequency curve.Such as said frequencies curve In minimum sample frequency be every 5 seconds 1 frames of acquisition, then the preset sample frequency can be each 5 seconds 1 frames of acquisition, can also Think every 6 seconds 1 frames of acquisition.

After acquiring indoor image according to the sample frequency, controller 111a will also call image Processing Interface, compare this An at least frame image for the image of acquisition and neighbouring acquisition judges indoor with the presence or absence of mobile people.Image collecting device 112a One frame image of every acquisition, all can store it according to timestamp.When having acquired present image, then transferred according to timestamp The previous collection period acquired image of current acquisition time.By the comparison of two frames or multiple image, indoor whether deposit judged In mobile people.

Further, when mobile people is not present in the controller indoors, the present sample of image collecting device is reduced Frequency, and according to the acquisition of the sample frequency progress off-the-air picture after reduction.When controller 111a monitors that indoor be not present is moved Dynamic people can then reduce the sample frequency of image collecting device, such as current sample frequency is every 6 seconds 1 frames of acquisition, then Sample frequency after reduction is every 10 seconds 1 frames of acquisition.When indoor there is no when mobile people, image collecting device 112a is no longer High-frequency Image Acquisition is needed, therefore by reducing sample frequency, to reach energy saving purpose.

Further, when the distance between people and air conditioner are worth, and are less than or equal to the first pre-determined distance, the controller Blower is with the first rotational speed；When the distance between people and air conditioner are worth, greater than the first pre-determined distance, and less than or equal to second When pre-determined distance, the controller blower is with the second rotational speed；It is preset when the distance between people and air conditioner value are greater than second Apart from when, the controller blower is with third rotational speed, wherein third revolving speed is greater than the second revolving speed, and the second revolving speed is greater than the One revolving speed.

Specifically, in the present embodiment, with the increase of distance, wind speed is gradually increased, so that between user and air conditioner Distance does not influence the air quantity received of user, i.e., when user is in air-supply region, whether in the first pre-determined distance or In second pre-determined distance, the air quantity that user is received is suitable, so that user does not feel as the mutation of wind speed, to have Conducive to the experience for improving user.

Further, the controller also utilizes the humidity detector of air conditioner to detect indoor humidity value,

Specifically, in the present embodiment, air conditioner further includes humidity detector, and humidity detector can be humidity sensor Device or other appliance arrangements that can detecte humidity.When humidity is smaller, wind speed is reduced, because humidity is smaller, thermal energy is in sky Transmitting in gas is slower, then the thermal energy that air-flow scatters and disappears in flow process is fewer, lower wind speed is ensured that More thermal energy is transferred to user.By taking refrigeration as an example, humidity is small, and cold energy scatters and disappears few, less air quantity can will be more Cold energy is conveyed to user.Same reason, when humidity is suitable, wind speed can be uncomfortable (between the first humidity and the second humidity) It is whole, at this point, current air quantity can satisfy the energy requirement of user；It needs to increase (when being greater than the second default humidity) when humidity is larger Add air quantity to increase energy, at this time, it may be necessary to improve the revolving speed of blower to increase air output.

Further, the controller also utilizes the light intensity test device of air conditioner to detect indoor humidity value,

Specifically, in the present embodiment, air conditioner further includes light intensity test device, and light intensity test device is that can detecte interior The instrument and equipment of light intensity.When light intensity value is smaller, i.e., light is very weak, when even without light, judges current environment at night Or the user in room does not need too many air quantity, at this point it is possible to which air quantity is reduced, i.e., drops rotation speed of fan without activity Low level-one；Similarly, it keeps revolving speed constant when light intensity value is moderate, when light intensity value is higher, increases revolving speed to increase air quantity.

Accordingly, the embodiment of the invention also provides a kind of control methods of air conditioner rotation speed of fan.As shown in figure 5, should The control method of air conditioner rotation speed of fan the following steps are included:

Step S110, it is monitored using the temperature-detecting device 117 on air conditioner indoor with the presence or absence of mobile heat source；

S120, when detect it is indoor there is mobile heat source when, utilize the image collecting device 112a on air-conditioning to monitor room The interior people with the presence or absence of movement；
