Description

Technical Field

[0001] The invention belongs to the technical field of teaching facilities, and in particular relates to a multimedia classroom intelligent control system with dynamic linkage between classroom light environment and teaching status. Background Art

[0002] Due to the long-term, close-range, and high-frequency use of mobile phones, tablets, phone watches and other electronic devices by young people, as well as the reduction of outdoor activity time, the prevalence of myopia among Chinese teenagers has been increasing rapidly and has remained at a high level for a long time, and the onset of myopia is becoming younger and younger. According to statistics, the prevalence of myopia among Chinese teenagers has reached 52.7%, so the prevention and control of myopia among teenagers is imminent.

[0003] Light environment is an important factor affecting refractive development. Light can stimulate the retina to promote the secretion of dopamine, thereby reducing the axial elongation of the eye axis, which is a possible channel for light to affect or inhibit the occurrence of myopia. Usually, teenagers spend 70% to 80% of their time in school in the classroom, so the quality of the classroom light environment will be directly related to the prevention and control of myopia in teenagers.

[0004] In the prior art, the light environment of the classroom is usually affected by the working state of the lighting and the shielding state of the curtains. Most of the lighting is controlled manually to control the light intensity, and the simpler ones can only control the switch state. However, due to the sudden changes in weather at different times such as noon and evening every day, the natural light intensity in the classroom will also change accordingly. At this time, it is difficult to ensure the balance of light intensity in the classroom by manually controlling the lighting, and it is easy to cause the classroom to be too bright or too dark. In addition, the existing curtains are usually set at the top of the window and are manually controlled to rise and fall. In order to block pedestrians and scenery passing by the window to prevent interference with learning, the curtains need to be manually lowered to completely block the window, but this will affect the lighting of the window. During the break, in order to provide students with a spacious and convenient view, the curtains need to be manually pulled up partially or completely, which is very troublesome to operate. Summary of the invention

[0005] In view of the above problems, the present invention provides a multimedia classroom intelligent control system that dynamically links the classroom light environment and the teaching status. The control system can automatically determine the teaching status of the multimedia classroom according to the dynamic behaviors of students and teachers in the classroom, and automatically control the working status of curtains and lighting fixtures to form a corresponding light environment mode, so that the classroom light environment and the teaching status are intelligently and dynamically linked. Moreover, by setting up rising fill light curtains to replace traditional curtains and performing secondary correction on the light environment mode, the classroom can always be maintained in a stable lighting environment to ensure healthy lighting and save energy in the multimedia classroom.

[0044] Further, in a more specific embodiment, please refer to Figure 1 The camera device 7 includes a rear camera 701 arranged on the side of the multimedia classroom away from the blackboard 1 and a front camera 702 arranged on the side of the multimedia classroom close to the blackboard 1; based on this setting, the front camera 702 and the rear camera 701 cooperate with each other to obtain more comprehensive video image information in the multimedia classroom, and because the teacher usually faces the rear camera away from the blackboard, and the students face the front camera towards the blackboard, the facial information of the teacher and the students can be better obtained and recognized through the front camera 702 and the rear camera 701 shooting at different angles.

[0045] Further, in a more specific embodiment, please refer to Figure 3 and Figure 4The rising type light-filling curtain 5 also includes a curtain roller 501 arranged below the window, curtain rollers 502 arranged on both sides above the window, curtain cords 504, and a driving mechanism 506; the lower end of the curtain cloth 503 is wound around the curtain roller 501, and both sides of the upper end of the curtain cloth 503 are connected to the curtain roller 502 through curtain cords 504, and the driving mechanism 506 drives the curtain roller 501 and the curtain roller 502 to rotate, and through the cooperation of the curtain cords 504, drives the curtain cloth 503 to rise or fall from the bottom of the window; in the present invention, since the curtain cloth 503 of the rising type light-filling curtain 5 is of the downward rising type, the curtain only needs to be raised from the bottom part to block the interference of outdoor pedestrians and scenery on students' learning, and will not completely affect the lighting.

[0046] Furthermore, in a more specific embodiment, the method for determining the current teaching status in the multimedia classroom is as follows: when the number of people in the personnel quantity information is 0, the multimedia classroom is in a retired state; when the number of people in the personnel quantity information is greater than 0, and the number of students sitting in the personnel behavior information is greater than i, the multimedia classroom is in a lunch break state; when the number of people in the personnel quantity information is greater than 0, and the number of students leaving their seats in the personnel behavior information is greater than j, the multimedia classroom is in a get out of class-off state; when the number of people in the personnel quantity information is greater than 0, and the number of students leaving their seats in the personnel behavior information is less than k, and the personnel identity information does not include a teacher, the multimedia classroom is in a self-study state; when the number of people in the personnel quantity information is greater than 0, and no student leaves his seat in the personnel behavior information, and the personnel identity information includes a teacher, the multimedia classroom is in a class state; in the present invention, the "sitting" means that the student sits down and rests on the desk; the "leaving" means that the student leaves the current seat.

[0047] Furthermore, in a more specific embodiment, the matching relationship between the light environment mode of the multimedia classroom and the teaching state is:

[0048] When the multimedia classroom is in a retired state, the corresponding light environment mode is that the curtain cloth 503 is retracted, and the blackboard lamp 4, the lighting lamp 3 and the LED flexible light strip 505 are turned off; that is, when the multimedia classroom is in a retired state, the classroom intelligent management and control module issues a command to control the curtain cloth 503 to descend, so that the curtain cloth 503 is retracted, and the blackboard lamp 4, the lighting lamp 3 and the LED flexible light strip 505 are controlled to be turned off; in this case, there are no students studying or teachers working in the classroom, and the system of the present invention can save energy by automatically turning off all lamps;

[0049] When the multimedia classroom is in a lunch break state, the corresponding light environment mode is that the curtain cloth 503 is fully raised, and the blackboard lamp 4, the lighting lamp 3 and the LED flexible light strip 505 are turned off; that is, when the multimedia classroom is in a lunch break state, the classroom intelligent management and control module issues a command to control the curtain cloth 503 to be fully raised to cover the window as a whole, and controls the blackboard lamp 4, the lighting lamp 3 and the LED flexible light strip 505 to be turned off; in this case, since the students are in a lunch break state, the system of the present invention can create a darker light environment by automatically raising the curtains for shielding and automatically turning off all lamps, which is conducive to improving the quality of students' rest;

[0050] When the multimedia classroom is in the off-get out of class state, the corresponding light environment mode is that the curtain cloth 503 is folded, the blackboard lamp 4 and the lighting lamp 3 are turned on, and the LED flexible light strip 505 is turned off; that is, when the multimedia classroom is in the off-get out of class state, the classroom intelligent management and control module issues an instruction to control the curtain cloth 503 to descend, so that the curtain cloth 503 is folded, and the blackboard lamp 4 and the lighting lamp 3 are turned on, and the LED flexible light strip 505 is turned off; in this case, after the students finish class, the curtains of the system of the present invention can be automatically folded, so that the environment in the classroom is brighter, and the students can look into the distance through the window to achieve the purpose of better relaxing their eyes and resting;

[0051] When the multimedia classroom is in a self-study state or a class state, the corresponding light environment mode is that the curtain cloth 503 is half-raised, the blackboard lamp 4, the lighting lamp 3 and the LED flexible light strip 505 are turned on, and the light intensity of the LED flexible light strip 505 is the same as the fill light intensity value; that is, when the multimedia classroom is in a self-study state or a class state, the classroom intelligent management and control module issues a command to first control the curtain cloth 503 to be in a half-raised state, and then controls the blackboard lamp 4, the lighting lamp 3 and the LED flexible light strip 505 to be turned on in turn, and adjusts the LED flexible light strip 505 when it is turned on. The light intensity of the light strip 505 is the same as the fill light intensity value; in this case, when students are studying or attending classes, the system of the present invention can automatically control the curtains to rise from the bottom to a half-raised state, which can not only effectively block pedestrians and scenery outside the classroom to avoid interference with learning, but also the curtains in a half-raised state will not completely block the light from the windows; in addition, due to the fill light effect of the LED flexible light strip 505, it can also make up for the light loss of the windows caused by the half-raised state of the curtains, so as to ensure that the light intensity in the classroom always meets the requirements of the normal illumination preset value.

[0052] Furthermore, in a preferred embodiment, the real-time light environment information includes whether there is glare in the multimedia classroom, the light intensity in the multimedia classroom, and whether the teaching multimedia all-in-one machine is reflective; the secondary adjustment is specifically as follows: when glare appears on one side of the multimedia classroom, an instruction is issued to control the curtain cloth 503 on the corresponding side of the glare to be adjusted from a half-raised state to a fully raised state; when the light intensity in the multimedia classroom is lower than or higher than the normal illumination preset value, an instruction is issued to adjust the illumination of the lighting lamp 3 and the LED flexible light strip 505 so that the light intensity in the multimedia classroom meets the normal illumination preset value requirements; when the teaching multimedia all-in-one machine is reflective, an instruction is issued to control the curtain cloth 503 to be adjusted from a half-raised state to a fully raised state, and at the same time, the illumination of the lighting lamp 3 and the LED flexible light strip 505 are adjusted so that the light intensity in the multimedia classroom is less than the brightness of the multimedia all-in-one machine.

[0053] Furthermore, in a preferred embodiment, the value ranges of i, j, k are 5-10, 10-15, and 1-5 respectively; when judging the teaching status in the multimedia classroom, the number of students sitting during lunch break, the number of students leaving their seats at the end of class, and the number of students leaving their seats during self-study can be counted, and then appropriate values ​​of i, j, and k are confirmed. Usually, the value ranges of i, j, and k are 5-10, 10-15, and 1-5 respectively.

[0054] In some special cases, such as when students arrive at school in the morning and leave school after school, only a small number of students may be active in the classroom at different time periods. In order to save energy, further, in a preferred embodiment, the lighting lamp 3 partitions are arranged at the top of the multimedia classroom 6, and the multimedia classroom 6 is divided into seating areas corresponding to the lighting lamp 3 partitions; the video image information processing and analysis module also includes: analyzing and counting the number of seated students in each seating area, and when the number of seated students in the target seating area and the adjacent seating area is 0, the seat area code information of the target seating area is sent to the classroom intelligent management and control module; the classroom intelligent The control module also includes: sending instructions to control the lighting lamp 3 of the corresponding partition to be turned off according to the received seat area code information; wherein the number of partitions of the lighting lamp 3 is greater than 12, and the sizes of the partitions are the same and are evenly arranged adjacent to each other in an array; in the above-mentioned setting, the present invention takes into account that the target seat area will not only receive the lighting of its corresponding partition lighting lamp, but also receive the lighting of the adjacent partition lighting lamp. Therefore, when screening the partition lighting lamps to be turned off, the present invention uses the condition that the number of seated students in the target seat area and the adjacent seat area is 0 as the screening condition, so as to minimize the lighting of the adjacent seat area where students are seated by the closed partition lighting lamp; for example, please refer to Figure 6, the classroom lighting of Class B of School A is evenly arranged in an array and divided into 16 zones, which are numbered 1-1, 1-2, 1-3, 1-4, 2-1, 2-2, 2-3, 2-4, 3-1, 3-2, 3-3, 3-4, 4-1, 4-2, 4-3, 4-4, where the first value in 1-1 represents the row number, the second value represents the column number, and the meanings of other numbers are the same; at a certain moment, the video image information processing and analysis module counts that the number of students sitting in the seating area corresponding to the lighting partitions numbered 1-3, 1-4, 2-3, 4-1, and 4-2 is greater than 0, while the number of students sitting in the remaining seating areas is 0, among which only the number of students sitting in the target seating area and the adjacent seating area corresponding to the lighting partitions numbered 1-1, 2-1, and 4-4 are 0, then the classroom intelligent management and control module sends instructions to control the lighting of the numbered 1-1, 2-1, and 4-4 to be turned off.

[0055] Example 2

[0056] In order to facilitate a better understanding of the working principle, advantages or innovations of the system of the present invention, this embodiment exemplifies the application process of the system of the present invention in Class B of School A on Day C, where the weather on Day C is sunny and then cloudy; in the system of the present invention, i, j, and k are respectively set to 6, 10, and 3; according to the "Design Specifications for Primary and Secondary Schools" GB 50099-2011 and relevant standard requirements, in the system of the present invention, the normal illumination preset value in the classroom is set to 500-550lx, that is, during the day when the curtains are all retracted and the windows are normally lit, the sunlight does not directly enter the classroom, the blackboard lamp 4 and the lighting lamp 3 are all turned on, and the blackboard lamp 4 and the lighting lamp 3 are operated at the default light intensity, the light intensity in the classroom is 500-550lx; in this system, the normal illumination preset value is set to 500-550lx, which is in a relatively narrow fluctuation range, thereby providing students with a stable lighting environment to prevent eye discomfort caused by excessive fluctuations in light intensity; the specific application process of the system of the present invention is as follows:

[0057] At 7:45 in the morning, Xiao Ming is the first to arrive in the classroom. At this time, the number of people in the multimedia classroom is 1, and the number of students sitting is 0, and the number of students leaving their seats is 49. The system determines that the multimedia classroom is currently in the end-of-get out of class state, and the classroom intelligent management and control module issues a command to control the curtain cloth 503 to descend so that the curtain cloth 503 is retracted, and controls the blackboard lamp 4 and the lighting lamp 3 to turn on at the default light intensity, and controls the LED flexible light strip 505 to turn off, thereby forming a light environment mode that matches the end-of-get out of class state; thereafter, the remaining 49 students arrive in the classroom one after another and have morning self-study in the time period of 8:00-8:20;

[0058] At 8:00, all the students have arrived at the classroom, but the teacher has not. At this time, the number of people in the multimedia classroom is 50, and the behavior information is that the number of students sitting down is 0 and the number of students leaving their seats is 0. The system determines that the multimedia classroom is currently in a self-study state, and the classroom intelligent management and control module issues a command to first control the curtain cloth 503 to be in a half-raised state. After the curtain cloth is half-raised, the natural light intensity in the multimedia classroom is slightly reduced, and the fill light intensity value detected by the light sensor 507 is 58lx.
