System has different processing methods：
Physical environment regulates and controls：Non- school session, the camera 1 in sliding rail 18 will be adjusted along sliding rail 18 to towards classroom heel row
The position at student seat, for monitoring classroom rear area, and be used for monitoring classroom in classroom front end ceiling side before
The acquisition indoor image information in classroom is sent in computer 5 camera 1 in square region jointly, is carried out at image for computer 5
Reason.Image that camera 1 photographed and be pre-stored in computer 5 one there is Benchmark brightness image to carry out brightness by computer 5
Comparison, method are to carry out grey scale difference processing using matlab.Picture with Benchmark brightness be camera 1 installation site with
The picture for including classroom image of equal angular shooting.After the luminance information for having analyzed image, computer 5 is according to the seat in classroom
Distribution, is divided into 8 regions, the wherein classroom front region captured by classroom front end ceiling side camera 1 is divided by classroom
It is in sphere of movements for the elephants shape for 4 regions, the classroom rear area captured by camera 1 in sliding rail 18 is also divided into 4 regions, is in
Sphere of movements for the elephants shape.Hereafter, the realtime graphic in above-mentioned 8 regions that computer 5 photographed camera 1 is at regular intervals (Millisecond)
Comparison is primary, if two images are variant, confirms that there are objects moving in the corresponding region of classroom, if variation range is more than through multiple
The threshold value set after experiment then judges that mobile object is behaved, that is, judges this region someone；If variation range is less than through repeatedly trying
The threshold value set after testing then judges mobile object for interfering objects such as fly, paper.Microcontroller 6 is transmitted by analyzing computer 5
Personnel's distributed intelligence and room brilliancy information, to electric light 7 carry out intelligent management：It is indoor nobody, electric light 7 is closed；It is indoor some
Region someone and room brilliancy are less than threshold value, then turn on corresponding region electric light 7.Indoor some region someone and room brilliancy is higher than
Threshold value then regulates and controls electric light 7 and curtain 14, to adjust room brilliancy.Temperature sensor 2, humidity sensor 3 and carbon dioxide pass
Sensor 4 acquires the indoor temperature information in classroom, humidity information and gas concentration lwevel information respectively, and corresponding informance is transmitted to
In microcontroller 6.Microcontroller 6 is by analyzing the personnel's distributed intelligence and temperature sensor 2 and humidity sensor 3 that computer 5 transmits
The temperature and humidity information of transmission carry out intelligent management to air-conditioning 10：(wet) degree of Indoor Temperature is low, then air-conditioning 10 sets (wet) degree of temperature
It is high；(wet) degree of Indoor Temperature is high, then it is low to set (wet) degree of temperature for air-conditioning 10.Microcontroller 6 is dense by analyzing the indoor carbon dioxide in classroom
Information is spent to regulate and control the push-rod electric machine 9 of control sliding window 8, and then controls Classroom air circulation, and specific practice is：Indoor titanium dioxide
Concentration of carbon is higher than threshold value, then opens sliding window 8；Indoor carbon dioxide concentration is less than threshold value, then closes sliding window 8；Work as Indoor Temperature
When spending low, cancel the opening state of sliding window 8, microcontroller 6 opens the inletting fresh air pattern of air-conditioning 10 at this time, completes in the room of classroom
Outer air circulation.
It gives lessons environment conditioning：School session, camera 1 in sliding rail 18, which along sliding rail 18 is moved to preset shooting, gives lessons and regards
Frequency position simultaneously turns to, and is sent in time in computer 5 to the lecture contents of teacher, the figure of giving lessons in real time that computer 5 will receive
As information is transmitted in display screen 17, teachers' instruction image information is seen clearly for heel row student.After teachers' instruction, microcontroller 6
The give lessons camera 1 of video location of shooting is will be moved to move along sliding rail 18 and be back to classroom intermediate region top end and turn to,
Continue to monitor heel row students ' behavior.Microcontroller 6 opens microphone 15 and sound equipment 16, to carry out the sound of teacher in classroom heel row
Amplification, does not hear teachers' instruction voice messaging for heel row student.Teacher remotely can send order by terminal 11 to microcontroller 6, single
Piece machine 6 executes order, remote control and regulation electric light 7, sliding window 8 and curtain 14 closed state, to control room brilliancy, to meet
To the different demands of room brilliancy under different teaching tempos (such as ppt patterns, writing on the blackboard pattern).
The present invention does not address place and is suitable for the prior art.
