Specific embodiment
In order that the technical problem to be solved in the present invention, technical scheme and beneficial effect become more apparent, below in conjunction with
Drawings and Examples, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only used
To explain the present invention, it is not intended to limit the present invention.
Fig. 1 is referred to, the air conditioning control method in present pre-ferred embodiments based on image recognition, including
Step S110, picks up the consecutive image in air-conditioning temp. controllable space at interval of Preset Time.It is empty using photographic head recording
Picture or video recording in the space of tune equipment place is with pending data analysiss.At interval of Preset Time, such as interval 5 seconds, 10 seconds, 20
Second, 30 seconds etc..
Step S120, is analyzed to the consecutive image, judges whether have users in the space.Using humanoid knowledge
Other function, analyzes the whether someone (user) in consecutive image.Further, opening can be by one or more user for analyzing
It is marked, to record the action of each user.
Yet further, step S120 is in particular：Consecutive image to being picked up is analyzed and draws air-conditioning temp. controllable
Changing unit in space；Then, judge whether the changing unit includes user.Acquired consecutive image is carried out to score
Analysis, draws the region or part of change therein, the people that changes so as to position in analyzing in the space of air-conditioning equipment place or
Thing.In fact, indeclinable part in consecutive image can also be analyzed also having users.Then, according to changing unit
Image information judges whether the changing unit includes user.
Step S130, if analyzing changing unit in step S120 includes one or more users, enters in air-conditioning equipment
While row sweeps pneumatic work, photographic head and its image analysis apparatus also track each user's motion track.If in step
Motion parts no user is analyzed in S120, then finishing control program.
Step S140, according to user and the relative movement track of the real-time blowing direction for sweeping pneumatic work, is adjusted to the user
Refrigeration or the supply for heating that place direction is exported.The regulation is the shifting for sweeping wind direction according to the relative air-conditioning of relative users
Dynamic rail mark, judges user to current refrigeration or the size of the supply of the demand for heating.Adjust output refrigeration or the confession for heating
Should measure and refer to：Adjust the operational factor of air-conditioning.Adjust in unit interval on certain direction the refrigerating capacity (energy) of output or
Heating capacity, can be realized by adjusting the modes such as blowing amount, blowing wind speed, cooling/heating temperature, blow-time.
In more detailed embodiment, it is blowing direction with reference to Fig. 2 (A), 2 (B), 2 (C), 3 (A) and 3 (B), F1, F2 is
Sweep wind swaying direction, the moving direction of F3, F4 for user A or B, the relative movement track according to user and blowing direction,
Adjust to the user place direction refrigeration for being exported or the supply for heating and be specially：
In blowing direction before the user place direction is reached and afterwards, if the user toward blowing direction skew such as Fig. 2
(A) shown in and 2 (B)；And/or, in blowing direction when the user place direction is reached, if the user is followed toward blowing direction moving
Move as shown in Fig. 2 (C), then it is assumed that the refrigerating/heating demand of the user is big, need to increase what is exported in the user place direction
Refrigeration or the supply for heating.
Blowing direction reach the user place direction before, if the user toward with sweep wind direction identical direction movement,
As shown in Fig. 3 (A)；And/or in blowing direction when the user place direction is reached, if the user is moved toward blowing direction is deviateed
It is dynamic, such as shown in Fig. 3 (B), then it is assumed that the refrigerating/heating demand of the user is low, the user place side is reached in blowing direction
Xiang Shi, reduces exported refrigeration or the supply for heating, wherein, in Fig. 3 (B), if user B is moved with F4 directions, user B
Translational speed just perform the exported refrigeration of reduction or the supply for heating more than wind swing speed is swept.
In more detailed embodiment, in one embodiment, increase the refrigeration that exported in the user place direction or
The supply for heating can be realized with a under type：The first：When the blowing direction for sweeping wind reaches the user place direction, if
Refrigeration, then increase refrigerating capacity；If heating, then heating capacity is increased；Second：The user place direction is reached in blowing direction
When, stopping is swept wind and is dried (blow-through) with fixed-direction, increases blow strength or slow down and sweep after the swing speed Preset Time of wind, then
Proceed default swing speed, cooling/heating amount, dry and emphasize to carry out sweeping pneumatic work.It is understood that can also be with above-mentioned
The first and the second way realize the increase of refrigeration or the supply for heating simultaneously, to meet relative users in the unit interval
Inside bigger refrigerating/heating demand.
Reduction can be realized with a under type in the user place direction refrigeration for being exported or the supply for heating：First
Kind：When blowing direction reaches the user place direction, if refrigeration, then reduce refrigerating capacity；If heating, then heating capacity is reduced；
Second：When blowing direction reaches the user place direction, stopping blowing, reduction blow strength or quickening are swept wind velocity and are preset
After time, it is further continued for carrying out presetting sweeping pneumatic work.It is understood that can also be with the first above-mentioned with the second way simultaneously
Realize the reduction of refrigeration or the supply for heating, the refrigerating/heating demand lower slightly within the unit interval to meet relative users.
Further, also include：The macroscopic features and its required refrigeration that store the user A or the supply for heating are inclined
It is good, and in the macroscopic features of pickup next time to the user A, performed to the user place direction with the preference for being stored and sweep pneumatic
The step of making.Thus, slowing down scanning speed when wind is swept through user A next time.Or next time sweep wind through user A when
Time can stop sweeping wind for a period of time, to being further continued for scanning after its blow-through Preset Time.
It follows that after the preference of determination user A, it is believed that its demand degree to cooling/heating amount to current state
It is higher, then wind is swept when the user A, can increase refrigerating capacity, increase heating capacity when heating when refrigeration.
Equally, if user B hides wind direction, move quickly through when sweeping wind, or directly skip.
Further, when user's request state change, change air-supply strategy.As certain user chases wind by A class users
Blow and become B class users and hide wind, then it is assumed that the demand of the user has met, then reduce air supply velocity, when reducing blow-through
Between, reduce refrigerating capacity etc..As be adapted to, certain user movement it is complete it is awfully hot need quickly cooling, only need to some colds after cooling down after a while
Maintain.
