Description

[Technical Field]

[0001] This application proposes an intelligent integrated multimedia control method for the Internet of Things (IoT), and belongs to the field of the Internet of Things (IoT) technology. [Background technology]

[0002] As scientific and technological advancements progress, the applications of Internet of Things (IoT) technology are becoming increasingly widespread, bringing greater convenience.

[0003] In the field of education, smart schools have emerged, but the multimedia control in smart schools is still not systematized, or multimedia in classrooms is controlled by the same control multimedia system. If the control multimedia system fails, all multimedia in the classroom becomes uncontrolled, paralyzing the entire intelligent integrated multimedia control system, or causing multimedia failures in classrooms. This can only be discovered during class, forcing teachers and students to change classrooms in the middle of a lesson, causing significant inconvenience to both. [Overview of the Initiative] [Means for solving the problem]

[0024] [Figure 1] This is a flowchart of the Internet of Things (IoT) intelligent integrated multimedia control method related to the present invention. [Modes for carrying out the invention]

[0025] Preferred embodiments of the present application will be described below with reference to the attached drawings. However, it should be understood that the preferred embodiments described herein are used solely for the purpose of describing and explaining the present application and are not intended to limit the present application.

[0026] As one embodiment of the present invention, an intelligent integrated multimedia control method for the Internet of Things (IoT) is provided, wherein the method is: The control terminal transmits the class schedule information for each classroom to the corresponding classroom's smart classroom information board. The system will cross-reference the class schedule information for the corresponding time slots on all smart classroom information boards. If it finds that there are no classes within the preset time slots for those time slots, it will turn off the main power, doors and windows, air conditioning, and facial recognition system for the corresponding classroom; otherwise, it will turn them on. The smart classroom information board in the classroom includes matching faces with those of students in classes with lessons during the corresponding time slots, determining the actual number of students present and absent, obtaining the attendance rate for each student, and transmitting the attendance rate for the corresponding curriculum to a control terminal via a local area network communication method.

[0027] The operating principle of the above technology is as follows: The control terminal transmits the class schedule information for each classroom to the corresponding smart classroom information board, and ensures that the corresponding class schedule information has been received by the smart classroom information board in each classroom. The system compares the class schedule information for the current time on the smart classroom information boards in all classrooms. If there are no classes scheduled, the shutdown execution module turns off the main power, doors and windows, air conditioning, and facial recognition system of the corresponding classroom, and conversely, the startup execution module turns these devices on. The number of students who actually arrive at the classroom is measured through the facial recognition system and compared with the list of students taking the designated class to determine the actual number of arrivals and absences, and then the attendance rate of each student is calculated. To enable further statistics and analysis, the smart classroom information board in each classroom transmits the attendance rate for the corresponding curriculum to the control terminal via local area network communication.

[0028] The effects of the above-mentioned technology are as follows: By comparing class schedule information with preset time slots, the system achieves automatic control of classroom environment equipment, improving energy efficiency while simultaneously reducing maintenance costs. The classroom environment can intelligently adjust based on the current curriculum schedule, eliminating the need for manual intervention and providing students with a more comfortable learning environment. Through the cooperation of a facial recognition system and smart classroom information boards, the system collects and transmits attendance rate data for each curriculum, providing important data support to educational administrators. By automatically shutting down equipment in unused classrooms, the system reduces unnecessary energy waste and improves resource utilization efficiency. The collection and transmission of attendance rate data provides important reference for school leaders and teachers, helping them evaluate teaching effectiveness, take appropriate intervention measures, and improve the quality of teaching. The overall effect of this technology is to increase the level of intelligence in classroom environment management, strengthen the school's monitoring and management capabilities over the teaching process, and provide data support for optimizing the teaching process.

[0029] As one embodiment of the present invention, an Internet of Things (IoT) intelligent integrated multimedia control method is provided, wherein the control terminal transmits the class schedule information of each classroom to the corresponding smart classroom information board in the classroom. To obtain information on the class schedule for each classroom, including the curriculum name, class time, and the teacher, The process involves processing the aforementioned class schedule information, arranging it according to the display format of the smart classroom guide, and forming the overall smart classroom guide display data, the smart classroom guide display data for each floor of each building, and the smart classroom guide display data for each classroom. The aforementioned smart classroom information display data is displayed on the smart classroom information display board, and the smart classroom information display data for each floor of each building and the smart classroom information display data for each classroom are transmitted via a local area network communication method to the corresponding smart classroom information display devices on each floor of each building and to the smart classroom information display devices for each classroom. When a failure occurs in the control terminal, any smart classroom guidance board in the classroom can become the control terminal. Specifically, an optimal alternative smart classroom guidance board can be selected based on the alternative smart classroom guidance board scoring model, and it can be used as the control terminal. The alternative smart classroom guidance board scoring model includes that it is represented by the following formula.

[0030]

Number

[0031] Here, Score1 is the first score, w1 is the weight coefficient, n is the total number of smart classroom guidance boards minus 1, and d i is the straight-line distance between the alternative smart classroom guidance board and the i-th smart classroom guidance board, t is the total number of classes in a semester in the classroom corresponding to the smart classroom guidance board, a is the total class time of each classroom in a semester, v is the network speed of the alternative smart classroom guidance board at the time when the scoring calculation is executed, and r represents the amount of transmission data currently being transmitted by the alternative smart classroom guidance board.

[0032] The operating principle of the above-mentioned technical means is as follows: After the control terminal acquires class schedule information for each classroom, including the curriculum name, class time, and teacher, this information is used to arrange subsequent display data. The class schedule information is processed and arranged based on the display format of the smart classroom guide board to form general smart classroom guide board display data, smart classroom guide board display data for each floor of each building, and smart classroom guide board display data for each classroom. The general smart classroom guide board display data is displayed on the general smart classroom guide board, and the smart classroom guide board display data for each floor of each building and the smart classroom guide board display data for each classroom are transmitted via a local area network communication method to the corresponding smart classroom guide board devices for each floor of each building and each classroom. In the event of a failure in the control terminal, any classroom's smart classroom guide board can act as the control terminal. The design of the alternative smart classroom guide board scoring model involves comprehensively considering various factors to select the optimal alternative smart classroom guide board, taking into account the distance between the alternative smart classroom guide board and each classroom, in order to ensure that the alternative equipment can cover all classrooms in the school as quickly as possible and to increase the response speed. The workload required for alternative smart classroom information boards will be evaluated by considering the total number of classes per semester for the classrooms corresponding to the smart classroom information boards and the total class hours for each classroom, thereby enabling a more balanced distribution of tasks. The network speed of the smart classroom information boards and the current amount of data being transferred will be considered at the time the evaluation calculation is performed, so that alternative devices can receive and transfer large amounts of data in a timely and efficient manner.

[0033] The effects of the above-mentioned technology are as follows: Classroom lesson schedule information, including display data for the general smart classroom directory, smart classroom directory on each floor of each building, and smart classroom directory in each classroom, can be intuitively displayed on the corresponding smart classroom directory, thereby providing teachers and students with clear curriculum schedule information. Lesson schedule information can be transmitted in real time to the smart classroom directory equipment in each classroom via a local area network communication method, ensuring timely updates and accuracy of lesson schedule information. In the event of a failure in the main control terminal, the system can quickly switch to an alternative smart classroom directory to ensure the continuous operation of the entire system. The alternative smart classroom directory scoring model helps in selecting the optimal alternative equipment, thereby improving the fault tolerance and stability of the system. By integrating the above functions, the efficiency of managing classroom lesson schedule information can be improved, enabling teachers and students to accurately obtain relevant information, while also enhancing the system's automation and intelligence levels. Through information transmission, real-time data updates, and fault tolerance mechanisms, the above-mentioned technology effectively enhances the efficiency and stability of classroom management in schools, providing teachers and students with better information services and a better user experience. The alternative smart classroom sign scoring model comprehensively considers various factors such as spatial arrangement, equipment load, and network conditions, allowing for a more holistic evaluation of the applicability of alternative equipment. By adjusting the weighting coefficients, the importance of different elements can be adjusted according to the actual situation, increasing the model's flexibility and applicability. By comprehensively considering multiple indicators, it helps select the most stable, responsive, and load-appropriate alternative smart classroom sign, enhancing system reliability and stability. Through this scoring model, the system can automatically select the optimal alternative smart classroom sign, reducing manual intervention and strengthening the system's intelligence.By enabling effective resource allocation among alternative smart classroom signage, avoiding resource waste, and improving overall resource utilization efficiency, it can better guarantee the stability, flexibility, and intelligence level of the classroom management system on campus, providing comprehensive consideration and selection.

[0034] The alternative smart classroom information board scoring model considers the sum of the distances between the alternative smart classroom information board and other smart classroom information boards, selecting the straight-line distance because smart classroom information boards use a local area network wireless communication method, and the straight-line distance is used during wireless transmission. As a result, the larger the sum of the distances between the alternative smart classroom information board and other smart classroom information boards, the lower its score. After an alternative smart classroom information board becomes a control terminal, it needs to transmit data to other smart classroom information boards. Therefore, if the smart classroom information board closest to the edge of the campus becomes a control terminal, it will consume a large amount of network resources when transmitting data to other smart classroom information boards. However, the optimal alternative smart classroom information board selected by the alternative smart classroom information board scoring model of this application will save network resources and avoid unnecessary expenditures. Considering the number of classes in each classroom that a smart classroom information board is assigned to, the more classes a smart classroom information board is assigned to, the lower its score. This is because the more classes a smart classroom information board is assigned to, the more frequently it is used. Lowering the score in this case reduces system redundancy, allows for adjustment of resource utilization, ensures rational resource use, and avoids increased expenditure due to excessive consumption. Considering the resource utility of alternative smart classroom information boards, the higher the network speed, the less data is currently being transmitted, resulting in a higher score and improving the overall network response speed of the system. A high-speed network and low data transmission volume allow alternative smart classroom information boards to communicate more quickly without putting excessive pressure on the overall network bandwidth. This helps to improve data transmission efficiency and ensure communication stability. Choosing alternative smart classroom information boards with high network speed and low data transmission volume optimizes network resource utilization to the fullest extent, avoids unnecessary network congestion and resource waste, and, with improved network speed and reduced data transfer volume, allows users to obtain necessary information more quickly, improving user experience and productivity. By selecting a high-performance alternative smart classroom information board, it is possible to effectively reduce additional costs caused by inappropriate use of network resources and achieve cost savings.Because network speed and data transfer rates can change over time in real-world situations, data that closely resembles actual usage is needed for evaluation. Therefore, to obtain an accurate assessment of the performance of the alternative smart classroom information board, data was selected for the time when score calculations were performed.

[0035] Therefore, considering the resource availability of alternative smart classroom information boards, particularly network speed and data transfer volume, has a significant impact on overall system efficiency, user experience, and cost reduction.

[0036] As one embodiment of the present invention, an Internet of Things (IoT) intelligent integrated multimedia control method is provided, which compares the class schedule information of all smart classroom information boards for the corresponding time period, and if it is found that there are no classes within the preset time period for the corresponding time, turns off the main power, doors and windows, air conditioner, and facial recognition system of the corresponding classroom, and turns them on otherwise. Within the preset matching time slot, the class schedule information for the corresponding time slot on the smart classroom information board is matched, If there are no classes within the corresponding preset time period and the infrared sensor in the classroom detects that there are no people in the classroom, or if there are people in the classroom but no classes are held, or if the system detects that there are classes within the corresponding preset time period, then control signals corresponding to the classroom's main power, doors and windows, air conditioning, multimedia, and monitoring systems will be transmitted using the ZigBee communication standard. After receiving a control signal, the system includes the corresponding operation of the classroom's main power supply, doors and windows, air conditioning, multimedia, and facial recognition system.

[0037] We will assume that 8:00 AM to 12:00 PM is the preset time slot for one curriculum, and 1:00 PM to 5:00 PM is the preset time slot for another curriculum.

[0038] If, 10 minutes before a preset time slot, the system detects that there are no classes during that time slot, and the infrared sensor in the classroom detects that there are no people in the classroom, then 10 minutes before 8:00 AM, the system detects that there are no people in the classroom and that there is no scheduled curriculum. In this case, the system controls corresponding devices via the Zigbee communication standard, such as turning off air conditioners, multimedia devices, and windows.

[0039] If there are no classes but people are in the classroom, or if there are classes within the corresponding preset time slot, and the system detects that someone entered the classroom 10 minutes before 8:00 AM, then there are no scheduled classes and the system will not take any action. If there are classes within the preset time slot of 8:00 AM to 12:00 PM and the system detects that there are no people in the classroom 10 minutes before 8:00 AM, the system will control the corresponding equipment, such as turning on the air conditioner or multimedia devices, via the Zigbee communication standard.

[0040] The operating principle of the above technology is as follows: The system compares the current time period curriculum information with preset time periods to check if there is a curriculum scheduled. It detects whether there are people in the classroom via an infrared sensor, and further combines this with class schedule information to determine whether it is necessary to control the classroom's main power, doors and windows, air conditioning, multimedia, and monitoring systems. If the conditions are met, the system uses the Zigbee communication standard to transmit control signals corresponding to the relevant equipment in the classroom. After receiving the control signals, the classroom's main power, doors and windows, air conditioning, multimedia, and facial recognition systems perform appropriate actions such as turning devices on / off.

[0041] The effects of the above-mentioned technology are as follows: Through an intelligent control system, the status of classroom equipment is automatically adjusted based on actual demand, effectively reducing energy waste. By enabling intelligent control of classroom equipment based on actual demand, a more comfortable learning environment can be provided for students and teachers. Manual operation of classroom equipment by maintenance personnel is reduced, lowering management costs. Classroom resources are optimized, allowing for better utilization of classroom resources, ensuring that equipment is available when needed and automatically turned off when idle, thereby increasing resource utilization efficiency. In summary, through intelligent control and automated management, this means improves the utilization efficiency of classroom equipment while simultaneously providing teachers and students with a better learning and teaching environment.

[0042] As one embodiment of the present invention, an Internet of Things (IoT) intelligent integrated multimedia control method is provided in which, after receiving a control signal, the corresponding classroom main power, doors and windows, air conditioner, multimedia, and facial recognition systems perform corresponding operations. Upon receiving a shutdown control signal, the main power, doors and windows, air conditioning, multimedia, and facial recognition systems of the corresponding classroom will perform a shutdown. Upon receiving a startup control signal, the corresponding classroom's main power, doors and windows, air conditioning, multimedia, and facial recognition systems execute startup. The corresponding classroom's smart classroom information board sends a message to the teacher's electronic device via local area network communication. The teacher sends courseware to the smart classroom information board. The smart classroom information board transmits the courseware to the classroom's multimedia via ZigBee communication standard. After receiving the courseware, the multimedia device places it on its desktop. In the event of a multimedia failure in a classroom, the system will select the most suitable alternative classroom from among available classrooms exceeding the capacity of the classroom being replaced, based on an alternative classroom scoring model, and will send notification information to the electronic devices of the students and teachers taking the class. The alternative classroom scoring model is represented by the following formula, and includes the following:

[0043]

number

[0044] Here, Score1 is the first score, Score2 is the second score, w1, w4, and w5 are weight coefficients, and X i This is the commuting distance between the substitute classroom and the classroom being substituted, C m This is the number of people that can be accommodated in the alternative classroom, C n This represents the number of people that can be accommodated in the classroom being substituted.

[0045] The operating principle of the above-mentioned technology is as follows: upon receiving a shutdown or startup control signal, the corresponding main power supply, doors and windows, air conditioning, multimedia, and facial recognition systems in the classroom perform the appropriate operations. If a courseware update is required, the smart classroom information board sends a message to the teacher's electronic device via the local area network communication method. After the teacher sends the courseware to the smart classroom information board, the smart classroom information board sends the courseware to the multimedia system in the classroom via the Zigbee communication standard. After receiving the courseware, the multimedia device displays it on its desktop for use in class. If a multimedia device in a classroom where a class is being held fails, the system selects the most suitable alternative classroom from available classrooms with a capacity exceeding that of the classroom being replaced, based on the alternative classroom grading model, and notifies the relevant parties.

[0046] The effects of the above-described technology are as follows: By sending messages to teachers' electronic devices via smart classroom information boards, rapid courseware updates are achieved. Simultaneously, courseware can be quickly transferred to classroom multimedia devices via the Zigbee communication standard and displayed on the desktop, improving teaching efficiency. If a multimedia device in a classroom experiencing a lesson fails, the system can quickly and intelligently select the most suitable alternative classroom, notify the relevant users, and ensure that teaching continues normally. Through the alternative classroom scoring model, the system can rationally select an alternative classroom, reducing teaching interruptions due to equipment failure and further optimizing the use of classroom resources. The automated processes for fault handling and alternative classroom selection reduce manual operation and help reduce management costs. Intelligent control of classroom equipment and intelligent selection of alternative classrooms enhance the stability and reliability of the overall learning environment. Through intelligent control and automated fault handling, this technology enhances the efficiency and stability of the teaching process while providing a more convenient solution for teaching management.

[0047] The alternative classroom scoring model considers the commuting distance between the alternative classroom and the original classroom, with higher scores given for shorter distances. Commuting distance considers the actual route teachers and students need to take to the alternative classroom, including road and traffic conditions. However, straight-line distance only considers the shortest distance between two points and does not account for the actual travel route. For example, students might need to detour around buildings or use corridors and stairs. Commuting distance is more accurate to real-world situations, considering actual walking or driving routes, making it suitable for evaluating alternative classroom selection. Therefore, the model can support decision-making that better matches actual needs. Considering classroom capacity, scores are higher for classrooms closer to the original capacity, avoiding switching to larger classrooms when there are fewer students, thus avoiding unnecessary resource waste and utilizing existing classrooms as much as possible. Considering the first scoring of the smart classroom information board, students need to sign in using the smart classroom information board after entering the alternative classroom. Factors such as the smart classroom information board's network bandwidth should also be considered to improve system response speed and overall user experience.
