Workflow: first according to the illumination intensity information that light intensity detection circuit module detects, determine whether start this device: (such as suitable illuminance of writing is 500lx to the illuminance reference value of setting before illuminance reaches, lx is illuminance unit), do not start, when light starts lower than during the reference value set.Once start, the number that control core module recipient counting number module (comprising the PC of video camera, runs image processing software) detects and Regional Distribution of Registered, according to the maximum number that each district can hold, determine the lamp in which region bright, when region number is discontented with or total number of persons specify region number scope under time, system automatic speech prompting, allows personnel take a seat Relatively centralized.

Technique scheme is known, the beneficial effects of the utility model: 1, indoor are divided into several regions, adopt image processing techniques to detect number and position, alarm is carried out to inappropriate personnel's distribution, realizes the automatic management of classroom illumination light fixture.System configuration is simple, economical and practical, has automatically and manual two kinds of functions, can effective saves energy, provides new method for classroom illumination manages; 2, illuminator can be made to carry out work by some states of setting, and these states automatically switched mutually by the time preset; Illumination can be adjusted to the most suitable level of work by intelligent lighting automatically, reaches energy-conservation effect; 3, have volume little, it is convenient to control, and reliability is high, and specificity is strong, and the advantages such as cost performance is reasonable, are with good expansibility, are easy to realize network management, meets the requirement that all kinds of large, special secondary school universities and colleges classroom lighting controls, reaches energy-conservation object.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, the utility model comprises: control core module, number counting module, ambient light intensity detection module, voice cue module etc., number counting module, ambient light intensity detection module, voice cue module are all connected with control core module.

As shown in Figure 2, described control core module is STC89C52 single-chip microcomputer process chip, there are 32 I/O(input/output end ports) port, the peripheral circuit connected by I/O port has start-oscillation circuit, reset circuit, voice alarm circuit, light intensity detection circuit and serial port level chance-over circuit.

Described single-chip microcomputer, by pin P1.0 JA(junction ambient) luminous intensity detection module, by pin P1.3 and P1.4 connecting lamp control mode conversion module, connects voice cue module by pin P1.5.

The range statistics module that described number counting module comprises classroom total number of persons statistical module and adds up region each in classroom, comprises video camera, PC etc.By classroom nobody time rest image and have dynamic image during people to compare to determine classroom number.Video camera first take classroom nobody time rest image, after denoising, the preliminary treatment such as level and smooth are carried out to image, it is converted to HSV space from rgb space, obtains the colourity of every bit, saturation and monochrome information and store it for background template, thus obtaining the background model in all regions.Human body counting flow process can be entered after completing initialization.As shown in Figure 3, gather actual classroom image, by Image semantic classification, be converted to HSV space from rgb space, obtain the HSV information of in regional often, then carry out point-to-point differential comparison with the background model of corresponding region.Setting HSV differential threshold and sign human body overlook the some cloud amount threshold of area.Difference HSV and count when simultaneously exceeding threshold value, then can assert it is human body target, can detect and obtain local area number after full figure.

Described ambient light intensity detection module is integrated with photo resistance, comparator and slide rheostat etc.The characteristic of photo resistance is: resistance strengthens with intensity of illumination and becomes large; The key property of comparator is: when positive input terminal voltage is greater than negative input end voltage, export as high level, on the contrary output low level.Based on the feature of these two kinds of devices, composition graphs 4 is known, when intensity of illumination is greater than set point, the voltage at 1 place higher than 2 places, then comparator output terminal 3 place output low level, whole system does not work; When intensity of illumination is lower than set point, 1 place's voltage is lower than 2 places, and comparator output terminal 3 place exports high level, and system normally starts.

As shown in Figure 5, lamp control mode conversion module: in automatic mode: utilize single-chip microcomputer pin P1.3 and P1.4 to control the light on and off of LED; When meeting certain condition, corresponding single-chip processor i/o pin can be low level, makes LED bright.When automatic mode occurs special status and can not normally run, switch S 1 and S2 can be utilized to carry out the light on and off state of Non-follow control LED.

This device has two kinds of control modes: automatic control state and Non-follow control two kinds of modes.Automatic control state: when ambient lighting is sufficient and classroom illumination intensity is greater than set point time, no matter have nobody, lamp does not all work.If classroom illumination intensity is less than set point, the switch of certain area lights is determined in the total number of persons that the information analysis that control core module can provide according to number counting module obtains and the region that people sits.Non-follow control: when device breaks down, pressing force switch can be controlled classroom lamp by force by people, to guarantee that light fixture can normally use.

The group number of turning on light determined by single-chip microcomputer according to classroom number signal, often organize 2 lamps, concrete logic is that below 10 people open one group of lamp, and 10-30 people opens two groups of lamps, more than 30 people opens three groups of lamps.

As shown in Figure 6, described voice cue module comprises pick-up, sound compression and processing module, sound storage module, sound broadcasting module.Pick-up gathers language information, sound compression and processing module are to the process of language Information Compression, and sound storage module is preserved, and sound broadcasting module is when needs, decode to language information, play, prompting religion indoor occupant takes a seat to appointed area.
