Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment and accompanying drawing, 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.
Embodiments provide a kind of lighting energy saving control system based on human bioequivalence, should comprise based on the lighting energy saving control system of human bioequivalence: for the camera head 10 of human body position;
Multiple lighting device 20;
Control device 40, is connected with described camera head 10 signal, and described control device 40 is connected by 30, relay with each lighting device 20; And obtaining the position coordinates of human body signal in the coordinate system of setting of described camera head 10 collection, described control device 40, according to the position coordinates obtained, controls the lighting device 20 corresponding with this position coordinates by relay 30 and throws light on.
Concrete, the single-chip microcomputer 42 that described control device 40 comprises computer 42 and is connected with described computer 42, described computer 42 is for obtaining the coordinate position of human body signal in described setting coordinate system according to the corresponding relation of the described human body signal of camera head 10 collection and the coordinate system of setting.
Camera head 10 wherein comprises multiple Kinect camera.This Kinect camera comprises: the asymmetric infrared projection machine of setting position, colour imagery shot and infrared camera.Relay 30 is wherein time-delay relay 30.
Conveniently to the understanding of the present embodiment, below in conjunction with accompanying drawing 1 and accompanying drawing 2, it is described in detail.
Fig. 1 gives the whole design idea of this system.Specifically, following four aspects are mainly comprised:
(1) seizure of scene video data flow is realized---specifically realized by Kinect camera;
(2) realization of human bioequivalence and the acquisition of positional information thereof---come by the application development based on C Plus Plus;
(3) formulation of data communication protocol between computer 42 and lamp dimmer---adopt RS232C physical layer standard;
(4) based on the lamp dimmer control loop of single-chip microcomputer 42 and relay 30.
Wherein, core is the identification of human body and the acquisition of positional information thereof.Specific implementation is the depth data stream being obtained object space by Kinect camera, is then separated from background noise by human body information; On this basis, carrying out analytical calculation to identifying human body information, drawing the position coordinates of human body; Finally, by formulating the communication protocol between computer 42 and single-chip microcomputer 42, according to the space coordinates of human body, control the lighting installation of corresponding position.
2.1 obtain contextual data stream and analyze the positional information of personnel in scene
Spatial information in scene is obtained by Kinect camera.Kinect camera is the Xbox360 somatic sensation television game accessory that Microsoft issued in 2010.It is a kind of 3D body sense video camera [1], has three asymmetric " eyes "---infrared projection machine, colour imagery shot and infrared camera.Wherein, colour imagery shot provides coloured image; Infrared projection machine Emission Lasers covers the visual range of Kinect; Infrared camera is by receiving the laser of reflections off objects, and " depth field " of recognition target object, for process computer 42 provides depth data.
Fig. 2 gives the recognition mode of depth image, here be that initial point sets up camera coordinate system with video camera, take camera axis as Z axis, to set up XY coordinate system perpendicular to Z axis plane, wherein Z axis coordinate figure represents the distance of object to camera plane of reality, the coordinate that XY coordinate figure presentation video frame is corresponding on video camera, concrete XY coordinate system is determined by the resolution of imaging sensor.To be drift angle be in the visual field of the Kinect taper shape of 57 degree, effective resolution distance is 4096mm, and maximum decipherment distance is 8192mm.
Consider the personnel location information in the mainly scene paid close attention to here, what therefore adopt is depth data stream.Meanwhile, in order to ensure reliability in time and the dynamic tracing precision of system, the depth image frame number of last display on computer 42 is locked in 30 frames, in order to avoid buffer overflow causes system crash here.Every frame depth image resolution is 640 × 480, and first 13 of each pixel are carried depth information, carry user ID after rear 3.
Obtaining in the process of human body information and position based on Kinect camera, by the application program developed based on C Plus Plus, first distribute different ID to different user, to distinguish different analytic targets.Then, adopt poll pattern to read in real time and store the depth image data of Kinect generation.Finally, the depth data carried according to each pixel in every frame depth image and user ID, identify human body, and follow the tracks of its change in location.
When user ID is 0, illustrate that user is not found in this position, such as value is 1 and 2, then show to identify " user 1 ", " user 2 ".And when identifying user, calculate its position coordinates, i.e. X, Z coordinate, wherein
Z=d, d are the degree of depth, extracting directly;
X＝((depthPixelBodyLeft-depthPixelBodyRight)/2+depthPixelBodyRight)×P；
Wherein P is the width of each pixel:
P＝2d×tan(28.5)/640；
The user coordinates value obtained is compared with the light position preset in system, thus provides data analysis for the light of switch relevant position.
2.2 control the adjustment of illuminating lamp according to personnel's distributional analysis
After the analysis of human bioequivalence and present position thereof, by formulating the communication protocol between computer 42 and lamp dimmer, according to the position of human body and illuminating lamp, the adjustment of illuminating lamp is controlled.Consider human body and close together between position analysis subsystem and lamp dimmer, adopt RS232C physical layer standard here, realize the asynchronous data communication of point-to-point.In the process realizing control signal output, consider that native system comprises multiple plug-in serial interface devices, when after lamp dimmer insertion system, its port numbers is by system Random assignment, therefore, by manually preparing its port numbers, the communication between computer 42 and controller is realized.
In addition, in order to ensure reliable transfer of data and signal light control, the command/response mechanism that data link layer protocol should adopt band to confirm, if can not get response correct in time, receiving-transmitting sides need reaffirm identity, and sets up synchronized relation.In a data link layer, we use the frame of three types, be respectively identity validation frame, communication state acknowledgement frame and signal light control command frame: identity validation frame, for realizing the plug-and-play feature of lamp dimmer, simplifies complicated communication port manual configuration process; Communications status acknowledgement frame is mainly used in the communication control function of lamp dimmer---because lamp dimmer can not receive new signal light control order at any time, after only having the signal light control command execution of last time, new order could be received; Signal light control command frame is mainly used in the signal light control command functions of lamp dimmer.
The form of signal light control command frame is " after preamble word (7EH)+command/response+information (elongated)+CRC+ synchronization character (7EH) ".Wherein, information field is defined as follows: first character saves the number of light sources in controlling, second byte and subsequent byte, every on off state corresponding to a light source, and 0 for closing, and 1 for opening, and its sequence number corresponds to light source sequence number.Here as required, 16 controllable light source are provided with at most.
3 theoretical energy consumption calculate and functional analysis
According to current design, the equipment of native system power consumption and device have Kinect camera, illuminating lamp, computer, comprise each device on the circuit board of relay 30 and the current loss in line transmission process, and their power consumption is as follows: (1) computer (for desktop computer) power is generally p
cabout=250W, for there being N
othe building in individual room, the power consumption in 1 hour of average each room is w
c=6/ (24N
0) kWh; (2) power of Kinect camera is p
k=12W, single camera work 1 hour, power consumption is w
k=0.012kWh; (3) what illuminating lamp (for University Classroom's) generally adopted is length is the fluorescent lamp of the T8 pipe of 1230mm, and power is 40W, and an illuminating lamp is made up of two fluorescent tubes usually, therefore the power of a lamp is p
l=80W, a hour power consumption w
kabout=0.08kWh; (4) comprise each device on the circuit board of relay 30, its power consumption is very low comparatively speaking, much smaller than the power consumption of aforementioned three kinds of equipment, so temporarily ignore.
Because in different building, the distribution of chummery intraoral illumination lamp is not different with flow of personnel situation, from comparatively simple situation, analyze the power consumption that native system is saved.Suppose that certain building (for teaching building) has N
oindividual same room, there is N in each room
lsmall cup lamp, illuminating lamp becomes two rows, is uniformly distributed.When someone H enters after room goes to certain seat, open the illuminating lamp above this seat.If H is t in seat residence time
w, after he leaves this seat, then corresponding illuminating lamp is closed.According to above-mentioned hypothesis, after H enters room, that turns in room only has a lamp all the time, and the accumulative time of opening is t
w, illuminating lamp power consumption p

Here first for the self-study at night electricity consumption in classroom in colleges and universities, the power consumption that native system is saved is calculated.If have N in certain teaching building
0=100 classrooms.Classroom varies, and from the ordinary circumstance of China Higher universities and colleges, about tens to one hundred, the seat in each classroom, about illuminating lamp 6-20 small cup (illuminating lamp above removing dais).Here each classroom is established to have two row totally 10 lamp (i.e. N
l=10), every lamp has 2 T8 fluorescent tubes.During self-study at night, the number in each classroom generally about a few people to tens people (study dull and rush season is different), considers native system mainly for energy waste design, simultaneously in order to simplify calculating, here suppose have 10 classmates to study by oneself in scheduled time in classroom every night, i.e. N
h=10, and the time of setting every classmate to stay in classroom in the time period needing to open illuminating lamp is as t
w=4h.The number of simultaneously staying in classroom is 5 people, and someone enters at every turn, all according to most sparse distribution (i.e. interpersonal square distance and maximum, a row people).
According to above-mentioned hypothesis, whole building is when there being native system to participate in controlling, and the power consumption of one day is W=N

c=354.8kWh.If Non-follow control, for the classroom of above-mentioned five bank lights, often arrange 2 lamps and generally use a switch control rule.Therefore, open a switch, two lamps can be turned on simultaneously.According to above-mentioned supposition, now, power consumption is W'=2N
0n

w=640kWh.Therefore, compared with Non-follow control, the power consumption saved for a day is Δ W=W'-W=285.2kWh.If the quantity in classroom increases, its energy-saving effect can be more remarkable.The electricity Δ W saved for 24 hours and classroom quantity N
obetween relation.When classroom number is less than 5, energy-conservation curve there will be negative value, this is because control system self power consumption causes.But, generally, the classroom quantity in teaching building is all being greater than between 5.For above-mentioned 100 classrooms, the use number of days in 1 year classroom by 277 days (according to " whole nation Spring Festival holidays and commemoration day have a holiday or vacation way " [5], remove outside the Spring Festival, have 8 day legal festivals and holidays, add 80 day winter and summer vacations, the classroom of 1 year is normally about 277 by the number of days used), add up to 79000.4kWh, kilowatt-hour, by 0.52 yuan, adds up to about 41080.21 yuan, just be recoverable to input less than 1 year, benefit comparison is considerable; If classroom reaches between 200, within 1 year, add up to the 159662.8kWh that saves energy, add up to about 83024.66 yuan, energy-saving effect is more tempting.
To sum up, computer 42 visually-perceptible is combined with light Based Intelligent Control by native system, by carrying out modeling and analytical calculation to associated scenario, according to the position distribution of personnel, controls the lighting installation in scene.The test prototype equipment that system has been produced, has that mechanism is simple, the feature of advantage of lower cost, is convenient to erection, or embeds building sensory perceptual system, can accept for user, be easy to popularization.In addition, control section uses modularized design, and for different occasions, different module of arranging in pairs or groups, can control corresponding equipment, and versatility is good, is easy to safeguard.Native system both may be used for personnel's dispersion, the flowings such as museum, classroom, station and had had probabilistic public place, and also can combine with monitoring camera realizes automatic alarm, has more wide application prospect.
These are only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
