[0002] The teaching environment is a complex overall system composed of various elements. It has a potential impact on students' cognition, emotion, and behavior during the learning process, and exerts a systematic intervention on the process and effect of teaching activities. It can be said that the quality of the teaching environment determines to some extent the effectiveness of teaching activities. In order to maximize the positive function of the teaching environment and reduce the negative function, and achieve the optimization of the teaching environment, it is necessary to carry out necessary adjustment and control of the teaching environment;

[0003] Especially during the computer teaching process, because the computer teaching content is complex, a better teaching environment is more needed in the classroom. During the process of classroom environment regulation, the classroom regulation system will be used.

[0004] The existing classroom regulation systems have a single regulation mode and poor regulation effects, which have a certain impact on the use of the classroom regulation system.

When the student quantity information is greater than the preset value and any one of the Q sound playback device volume size information T is less than the preset value, the second control information is generated. At this time, the content of the second control information is to increase the volume information of the playback device.

[0017] Furthermore, the specific generation process of the second control information further includes the following steps: Extract the collected student location information and extract the classroom floor plan from the classroom information;

[0018] After that, extract the center point of the classroom floor plan, use it as the origin, use the length and width of the classroom as the x-axis and y-axis, and classify the classroom floor plan into the first area, the second area, the third area, and the fourth area;

[0019] Mark the student location information in the first area, the second area, the third area, and the fourth area, and obtain the number of students in the first area, the number of students in the second area, the number of students in the third area, and the number of students in the fourth area;

[0020] Extract the volume size information of the sound playback devices in the first area, the second area, the third area, and the fourth area;

[0021] When the number of students in the first area is greater than the preset value, but the volume size information of the sound playback device is less than the preset decibel value, the second regulation information is generated. At this time, the second regulation information is to increase the volume of the first area. When the number of students in the first area is less than the preset value, but the volume size information of the sound playback device is greater than the preset decibel value, the second regulation information is generated. At this time, the second regulation information is to decrease the volume of the first area;

[0022] The determination processes for the second area, the third area, and the fourth area are the same as that of the first area.

[0023] Furthermore, the specific processing process of the third regulation information is as follows: Extract the collected teacher information, then extract the collected classroom environment information and classroom information. After that, extract the outdoor temperature information and the indoor temperature information from the classroom environment information and classroom information. The teacher information is the classroom age information. When the teacher age information is greater than the preset value, process the outdoor temperature information and the indoor temperature information to obtain the third regulation information.

[0024] Furthermore, the specific process of processing the outdoor temperature information and the indoor temperature information to obtain the third regulation information is as follows: Extract the outdoor temperature information and the indoor temperature information. When the outdoor temperature information is greater than the preset temperature a1 and the indoor temperature information is greater than the preset temperature a2, the third regulation information is generated.

At this time, the specific content of the third regulation information is to regulate the indoor temperature to the preset temperature b2;

[0026] The preset temperatures b1 and b2 are range values, 22 ≤ b1 ≤ 26, 18 ≤ b2 ≤ 22.

[0027] Furthermore, the specific processing process of the fourth regulation information is as follows: Extract the collected classroom information and playback device information. Extract the classroom area information from the classroom information, and then extract the number information of the sound playback devices from the playback device information.

[0028] Then, extract the brightness information of the image playback device from the playback device information, collect the brightness information of the image device every preset time interval for m consecutive times, where m≥5. After that, calculate the average value of the brightness information of the image device m times, that is, obtain the average brightness information. When the average brightness information is less than the preset value, the fourth adjustment information is generated. At this time, the content of the fourth adjustment information is the maintenance information of the image playback device.

[0029] Furthermore, the process of obtaining the evaluation parameter is as follows: Extract the collected classroom area information and the number information of the sound playback devices.

[0030] The beneficial effects of the present invention are reflected in: The intelligent classroom control system based on computer teaching processes the external outdoor environment information and the indoor environment information in the classroom, and generates the first adjustment information in a timely manner for adjustment when abnormalities are found, so that the environment in the classroom is always in a relatively comfortable state, enabling students to focus more on learning based on the teaching content. By processing the student information and the playback device information, the second adjustment information is generated to control the sound playback device to intelligently adjust the sound volume information of the sound playback device, thus avoiding the situation where the speaking sound is too loud or too small and affecting the students' learning of the teaching content. Through the generated third adjustment information, on the basis of generating the second adjustment information for environmental adjustment, more consideration is given to the age status of the teaching teacher for environmental adjustment, enabling the teaching teacher to teach better.

[0031] In order to more clearly illustrate the specific embodiments of the present invention or the technical solutions in the prior art, the following will briefly introduce the drawings required for the description of the specific embodiments or the prior art. In all the drawings, similar elements or parts are generally identified by similar reference numerals. In the drawings, the elements or parts are not necessarily drawn to scale.

[0032] Figure 1 It is the system block diagram of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following will describe in detail the embodiments of the technical solutions of the present invention with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, so they are only examples and cannot be used to limit the protection scope of the present invention.

[0034] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meanings understood by those skilled in the art to which the present invention pertains.

[0035] As Figure 1 shown, this embodiment provides a technical solution: an intelligent classroom control system based on computer teaching, including a classroom information collection module, an environmental information collection module, a teacher information collection module, a playback device collection module, a student information collection module, a data processing module, and an information sending module;

[0036] The classroom information collection module is used to collect classroom information, and the environmental information collection module is used to collect classroom environmental information;

[0037] The teacher information collection module is used to collect teacher information, the playback device collection module is used to collect playback device information, and the student information collection module is used to collect student information;

[0038] The data processing module is used to process classroom information, classroom environmental information, teacher information, playback device information, and student information to generate first control information, second control information, third control information, and fourth control information;

[0039] The information sending module is used to send the above information to a preset receiving terminal after the first control information, second control information, third control information, and fourth control information are generated;

[0040] The present invention processes external environmental information and indoor environmental information in the classroom, generates first control information in a timely manner for regulation when abnormalities are found, so that the environment in the classroom is always in a relatively comfortable state, enabling students to focus more on learning teaching content. By processing student information and playback device information, second control information is generated to control the sound playback device to intelligently regulate the sound volume information of the sound playback device, thereby avoiding the situation where the speaking voice is too loud or too small and affecting students' learning of teaching content. Based on the generation of the second control information for environmental regulation, the third control information is generated to further consider the age status of the teaching teacher for environmental regulation, enabling the teaching teacher to teach better. By generating the fourth control information, the image playback device and sound playback device in the classroom are regulated, thereby providing more stable hardware to support teaching, and thus realizing more intelligent regulation of the classroom.

[0041] The specific processing process of the first control information is as follows: Extract the collected classroom environment information and classroom information. The classroom environment information includes outdoor environment brightness information and outdoor temperature information, and the classroom information includes indoor brightness information, indoor temperature information, and indoor carbon dioxide concentration information;

[0042] When both the outdoor environment brightness information and the indoor brightness information are greater than the preset value, the first control information is generated. At this time, the content of the first control information is to adjust the brightness of the playback device;

[0043] When the outdoor temperature information is greater than the preset value a1 and the indoor temperature information is greater than the preset value a2, the first control information is generated. When the outdoor temperature information is less than the preset value a3 and the indoor temperature information is less than the preset value a4, the first control information is generated. At this time, the content of the first control information is to adjust the indoor temperature;

[0044] When the indoor carbon dioxide concentration information is greater than the preset value, the first control information is generated. At this time, the content of the first control information is to adjust the air circulation in the classroom;

[0045] Through the above process, the impact of the indoor environment on teaching is fully considered. For example, when the external temperature is low and the indoor temperature is also low, or when the external temperature is high and the indoor temperature is also high, it will affect the students' learning. At the same time, factors such as the indoor carbon dioxide concentration information are also considered. If the carbon dioxide concentration information is too high, it will cause students to feel oxygen-deficient and drowsy, which will greatly affect the students' learning of teaching content. Therefore, it is crucial to generate the first control information in a timely manner for environmental adjustment.

[0046] The specific processing process of the second control information is as follows: Extract the collected student information, and the student information includes student quantity information and student location information;

[0047] After that, extract the playback device information, and the playback device information includes the quantity information of the sound playback devices and the volume size information of the sound playback devices;

[0048] Extract the collected student quantity information, the quantity information of the sound playback devices, and the volume size information of the sound playback devices. Mark the quantity information of the sound playback devices as Q and the volume size information of the sound playback devices as T. When the student quantity information is greater than the preset value and any one of the Q volume size information T of the sound playback devices is less than the preset value, the second control information is generated. At this time, the content of the second control information is to increase the volume information of the playback device. The specific generation process of the second control information further includes the following steps: Extract the collected student location information, and then extract the classroom floor plan from the classroom information.

[0049] After that, the center point of the classroom floor plan is extracted. Taking it as the origin, with the length and width of the classroom as the x-axis and y-axis, the classroom floor plan is classified into the first area, the second area, the third area, and the fourth area;

[0050] Mark the student location information in the first area, the second area, the third area, and the fourth area, and obtain the number of students in the first area, the number of students in the second area, the number of students in the third area, and the number of students in the fourth area;

[0051] Then, extract the volume size information of the sound playback devices in the first area, the second area, the third area, and the fourth area;

[0052] When the number of students in the first area is greater than the preset value, but the volume size information of the sound playback device is less than the preset decibel value, a second regulation information is generated. At this time, the second regulation information is to increase the volume of the first area. When the number of students in the first area is less than the preset value, but the volume size information of the sound playback device is greater than the preset decibel value, a second regulation information is generated. At this time, the second regulation information is to decrease the volume of the first area;

[0053] The determination processes for the second area, the third area, and the fourth area are the same as that of the first area;

[0054] Through the above process, the intelligent regulation of the volume size of the sound playback device is realized, and the intelligent regulation of the sound size is carried out according to the number of students in different areas, so as to avoid the situation that the sound is too loud or too small and affects the students' listening to the content taught by the teacher.

[0055] The specific processing process of the third regulation information is as follows: Extract the collected teacher information, and then extract the collected classroom environment information and classroom information. After that, extract the outdoor temperature information and the indoor temperature information from the classroom environment information and classroom information. The teacher information is the classroom age information. When the teacher age information is greater than the preset value, process the outdoor temperature information and the indoor temperature information to obtain the third regulation information;

[0056] Through the above process, the state of the teacher is fully considered to intelligently adjust the environment information in the classroom, so that the teacher can teach better.

[0057] The specific process of processing the outdoor temperature information and the indoor temperature information to obtain the third regulation information is as follows: Extract the outdoor temperature information and the indoor temperature information. When the outdoor temperature information is greater than the preset temperature a1 and the indoor temperature information is greater than the preset temperature a2, a third regulation information is generated. At this time, the specific content of the third regulation information is to adjust the indoor temperature to the preset temperature b1, which can be used in summer;

[0058] When the outdoor temperature information is less than the preset temperature a3 and the indoor temperature information in the classroom is less than the preset temperature a4, the third regulation information is generated. At this time, the specific content of the third regulation information is to regulate the indoor temperature to the preset temperature b2, which can be used in winter;

[0059] The preset temperatures b1 and b2 are range values, 22 ≤ b1 ≤ 26, 18 ≤ b2 ≤ 22;

[0060] Through the above process, a more user-friendly temperature adjustment in the classroom is carried out.

[0061] At the same time, the specific processing process of the third regulation information also includes:

[0062] Extract the material information of the items in the teacher's teaching area and the material information of the items in the first area, second area, third area and fourth area where the students are located from the classroom information;

[0063] According to the material information of the items, obtain the thermal conductivity of the corresponding item materials from the Internet database, and further adjust the values of the preset temperatures b1 and b2 based on the magnitude of the thermal conductivity. Since the greater the thermal conductivity, the stronger its ability to transfer heat, at the same room temperature, the lower the perceived temperature of the item with a greater thermal conductivity. For example, the thermal conductivity of iron is greater than that of wood. If the desks or frequently contacted items in the area are made of iron, the corresponding perceived temperature is lower. After determining the material information of the items in the teacher's teaching area and the material information of the items in the first area, second area, third area and fourth area where the students are located, appropriately increase or decrease the corresponding temperature based on the magnitude of the thermal conductivity. The amplitude of the increase or decrease in temperature can be divided according to the level of the thermal conductivity. Multiple thermal conductivities are divided into different levels, and each level corresponds to a corresponding temperature amplitude. The specific value of the temperature amplitude can be preset to 0 - 3 degrees Celsius.

[0064] The specific process of adjustment is to compare the thermal conductivity of the item material with the preset thermal conductivity Z1. If it is greater than the preset thermal conductivity Z1, the temperature can be increased correspondingly according to the level of the thermal conductivity on the basis of b1 or b2. The greater the thermal conductivity, the greater the increase in temperature.

[0065] If the thermal conductivity of the item material is compared with the preset thermal conductivity Z2 and is less than the preset thermal conductivity Z2, the temperature can be decreased correspondingly according to the level of the thermal conductivity on the basis of b1 or b2. The smaller the thermal conductivity, the greater the decrease in temperature. Z1 > Z2.

[0066] The temperature can be regulated more precisely according to the material information of the items in the teacher's teaching area and the material information of the items in the first area, second area, third area and fourth area where the students are located, making the teacher and students more comfortable.

[0067] The specific processing process of the fourth control information is as follows: Extract the collected classroom information and playback device information, extract the classroom area information from the classroom information, and then extract the quantity information of the sound playback devices from the playback device information. After that, process the classroom area information and the quantity information of the sound playback devices to obtain an evaluation parameter. When the evaluation parameter is less than the preset value, the fourth control information is generated. At this time, the content of the fourth control information is to supplement the sound playback devices;

[0068] Then extract the brightness information of the image playback devices from the playback device information, collect the brightness information of the image devices once every preset time period for m consecutive times, where m≥5. After that, calculate the average value of the brightness information of the image devices for m times, that is, obtain the average brightness information. When the average brightness information is less than the preset value, the fourth control information is generated. At this time, the content of the fourth control information is the maintenance information of the image playback devices;

[0069] Through the above process, the teaching devices based on computer teaching can be intelligently controlled to ensure their stable operation.

[0070] The process of obtaining the evaluation parameter is as follows: Extract the collected classroom area information and the quantity information of the sound playback devices, mark the classroom area information as P1, and mark the quantity information of the sound playback devices as P2. After that, obtain the evaluation parameter through the formula P1 / P2*α = Pp, where 0.95≤α≤0.99, and α is directly proportional to the classroom area information P1.

[0071] Moreover, for the above-mentioned multiple intelligent adjustment methods, teachers or students can also make manual control adjustments according to their own needs, making the entire control system more user-friendly.

[0072] Finally, it should be noted that: The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and the description of the present invention.
