Description

An intelligent integrated multimedia control method and system for the Internet of Things Technical Field

[0001] The present invention provides an Internet of Things intelligent integrated multimedia control method and system, belonging to the technical field of the Internet of Things. Background Art

[0002] With the continuous advancement of science and technology, the application of Internet of Things technology is becoming more and more extensive, bringing us convenience.

[0003] In the field of teaching, although smart campuses have emerged, the multimedia control of smart campuses is still not systematic enough, or the multimedia in the classroom is controlled by the same control multimedia. When the control multimedia fails, the multimedia in all classrooms will not be able to be controlled, and the entire intelligent integrated multimedia control system will be paralyzed. Sometimes the multimedia in the scheduling classroom is damaged, and it can only be discovered during the class, causing teachers and students to have to change classrooms during class, which brings great inconvenience to teachers and students.

[0004] Summary of the Invention

[0005] The present invention provides an Internet of Things intelligent integrated multimedia control method and system to solve the above-mentioned problems:

[0008] Compare the class schedule information of all electronic class boards for the corresponding time periods. If there are no classes within the preset time period, turn off the main power, doors and windows, air conditioning, and facial recognition system of the corresponding classroom; otherwise, turn them on.

[0009] The face is compared with the faces of the classes in the corresponding time period to form the actual number of attendees and the number of absentees, and the attendance rate of each student is obtained. The electronic class board in the classroom then sends the attendance rate of the corresponding course to the control terminal via LAN communication.

[0010] Furthermore, the control terminal sends the class schedule information of each classroom to the electronic class board of the corresponding classroom, including:

[0011] Obtaining the class schedule information for each classroom, including the course name, class time, and teacher;

[0014] When the control terminal fails, the electronic class sign in any classroom can become the control terminal. Specifically, the best backup electronic class sign is selected according to the backup electronic class sign scoring model to make it the control terminal.

[0027] Compare the capacity of the multimedia damaged classroom with the available vacant classrooms, and select the vacant classrooms whose capacity of the selected backup classroom is greater than or equal to the capacity of the classroom to be replaced;

[0028] Based on the backup classroom scoring model, the backup classroom with the highest score is selected from the eligible backup classrooms as the best backup classroom;

[0029] Through LAN communication, a notification message about changing classrooms is sent to teachers and students who are going to attend classes in multimedia damaged classrooms.

[0055] FIG1 is a schematic diagram of an intelligent integrated multimedia control method for the Internet of Things according to the present invention. DETAILED DESCRIPTION

[0056] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0057] One embodiment of the present invention provides an intelligent integrated multimedia control method for the Internet of Things, the method comprising:

[0058] The control terminal sends the class schedule information of each classroom to the electronic class board of the corresponding classroom;

[0059] Compare the class schedule information of all electronic class boards for the corresponding time periods. If there are no classes within the preset time period, turn off the main power, doors and windows, air conditioning, and facial recognition system of the corresponding classroom; otherwise, turn them on.

[0060] The face is compared with the faces of the classes in the corresponding time period to form the actual number of attendees and the number of absentees, and the attendance rate of each student is obtained. The electronic class board in the classroom then sends the attendance rate of the corresponding course to the control terminal via LAN communication.

[0061] The working principle of the above technical solution is as follows: the control end is responsible for sending the class schedule information of each classroom to the corresponding electronic class board to ensure that the electronic class board in each classroom has the corresponding class schedule information; the system will compare the class schedule information of the electronic class boards of all classrooms in the current time period. If there is no course schedule, the shutdown module will be executed to turn off the main power, doors and windows, air conditioners and face recognition system of the corresponding classroom. Otherwise, the opening module will be executed to turn on these devices; the number of students who actually arrive in the classroom is detected by the face recognition system, and compared with the list of students attending the scheduled courses to determine the actual number of attendees and the number of absentees, and then the attendance rate of each student is calculated; the electronic class board of the classroom will send the attendance rate of the corresponding course to the control end through the local area network communication method for further statistics and analysis.

[0062] The effects of the above technical solution are as follows: by comparing class schedule information and preset time periods, the system realizes automatic control of classroom environment equipment, improves energy utilization efficiency, and reduces the operating costs of maintenance personnel; the classroom environment can be intelligently adjusted according to the current course schedule without manual intervention, thereby providing students with a more comfortable learning environment; through the collaboration of facial recognition system and electronic class board, the system can collect and transmit attendance data for each course, providing important data support for teaching managers; by automatically shutting down equipment in unused classrooms, the system helps to reduce unnecessary energy waste, thereby improving resource utilization efficiency; the collection and transmission of attendance data provides an important reference for school leaders and teachers, helps to evaluate teaching effectiveness, and take corresponding intervention measures to improve teaching quality; the comprehensive effects of this technical solution include improving the intelligence level of classroom environment management, enhancing the school's monitoring and management capabilities of the teaching process, and providing data support to optimize the teaching process.

[0063] One embodiment of the present invention is an Internet of Things intelligent integrated multimedia control method, in which a control terminal sends each classroom's class schedule information to an electronic class board of the corresponding classroom, including:

[0064] Obtaining the class schedule information for each classroom, including the course name, class time, and teacher;

[0065] Processing the class schedule information and arranging it according to the display format of the electronic class board to form overview class board display data, class board display data for each floor of each building, and class board display data for each classroom;

[0066] The overview class board display data is displayed on the overview class board, and the class board display data of each floor of each building and the class board display data of each classroom are respectively transmitted to the electronic class board device of the corresponding floor and the electronic class board device of each corresponding classroom through a local area network communication method;

[0067] When the control terminal fails, the electronic class sign in any classroom can become the control terminal. Specifically, the best backup electronic class sign is selected according to the backup electronic class sign scoring model to make it the control terminal. The backup electronic class sign scoring model is as follows:

[0068] Among them, Score 1 is the first score, w1 is the weight coefficient, d i is the straight-line distance between the backup electronic class sign and the i-th electronic class sign, t is the total number of classes scheduled in the classroom corresponding to the electronic class sign in one semester, a is the total number of class hours in each classroom in one semester, v is the network speed of the backup electronic class sign at the moment of performing the scoring calculation, and r is the amount of data currently being transmitted by the backup electronic class sign.

[0069] The working principle of the above technical solution is as follows: the control terminal obtains the class schedule information of each classroom, including the course name, class time, and teacher. This information will be used for subsequent display data arrangement. The class schedule information is processed and arranged according to the display format of the electronic class board, forming the overview class board display data, the class board display data for each floor of each building, and the class board display data for each classroom. The overview class board display data is displayed on the overview class board, and the class board display data for each floor of each building and each classroom is transmitted to the electronic class board device on the corresponding floor and the electronic class board device in each corresponding classroom via local area network communication. If the control terminal fails, the electronic class board of any classroom can become the control terminal. The best backup electronic class board is selected according to the backup electronic class board scoring model and becomes the control terminal. The design of the backup electronic class sign scoring model comprehensively considers multiple factors to select the best backup electronic class sign. The distance between the backup electronic class sign and each classroom is taken into account to ensure that the backup equipment can cover the classrooms in the entire campus as soon as possible and improve the response speed; the total number of classes scheduled in a semester in the classroom corresponding to the electronic class sign and the total number of class hours in each classroom are taken into account to evaluate the workload that the backup electronic class sign needs to bear, so as to distribute the tasks more evenly; the network speed and current transmission data volume of the backup electronic class sign at the moment of performing the scoring calculation are taken into account to ensure that the backup equipment can receive and transmit large amounts of data in a timely and efficient manner.

[0070] The effects of the above technical solution are as follows: classroom schedule information can be intuitively displayed on the corresponding electronic class board, including the overview class board, the class board for each floor of each building, and the class board display data for each classroom, thereby providing teachers and students with clear course schedule information; through LAN communication, the schedule information can be transmitted to the electronic class board equipment in each classroom in real time, ensuring the timely update and accuracy of course information; when the main control terminal fails, the system can quickly switch to the backup electronic class board to ensure the continuous operation of the entire system. The backup electronic class board scoring model can help select the best backup equipment, thereby improving the fault tolerance and stability of the system; integrating the above functions can improve the management efficiency of classroom schedule information, ensure that teachers and students can accurately obtain relevant information, and also improve the automation and intelligence level of the system; the above technical solution can effectively improve the efficiency and stability of school classroom management through the design of information transmission, real-time data update and fault-tolerant mechanism, and provide teachers and students with better information services and user experience. The backup electronic class sign scoring model comprehensively considers multiple factors such as spatial layout, equipment load, and network conditions, and can more comprehensively evaluate the applicability of backup equipment; by adjusting the weight coefficient, the importance of different factors can be adjusted according to actual conditions, making the model more flexible and applicable; taking multiple indicators into consideration comprehensively can help select the most stable, fast-responding and load-appropriate backup electronic class sign, thereby improving the reliability and stability of the system; through such a scoring model, the system can automatically select the best backup electronic class sign, reduce manual intervention, and enhance the intelligence of the system; it can help to effectively allocate resources among backup electronic class signs, avoid resource waste, and improve the overall resource utilization efficiency; it can better ensure the stability, flexibility and intelligence level of the classroom management system on campus, and provide comprehensive considerations and choices.

[0071] The standby electronic class board model considers the total distance between the standby electronic class board and other electronic class boards and selects the straight-line distance because the electronic class board adopts the wireless communication mode of the local area network, and the straight-line distance is adopted for wireless transmission. The greater the total distance between the standby electronic class board and other electronic class boards, the lower the score. Because the standby electronic class board needs to send data to other electronic class boards after becoming the control end, if the electronic class board closest to the edge of the entire campus becomes the control end, when it sends data to other electronic class boards, it greatly consumes network resources. The best standby electronic class board selected by the standby electronic class board scoring model of the present invention can greatly save network resources, make full use of network resources, and avoid unnecessary expenses; considering the number of classes scheduled in the classroom corresponding to the electronic class board, the more classes the electronic class board corresponds to, the lower the score, because the more classes the corresponding classroom has, the more frequently the electronic class board is used. At this time, lowering its score can reduce the redundancy of the system, adjust resource utilization, ensure that resources are reasonably utilized, and avoid increased expenses caused by excessive consumption; considering the resources of the standby electronic class board Source availability, the higher the network speed, the less the current amount of data transmitted, the higher the score, which can improve the network response speed of the entire system; high-speed network and low data transmission volume mean that the backup electronic class sign can communicate more quickly and will not cause excessive pressure on the overall network bandwidth, which will help improve the efficiency of data transmission and ensure the stability of communication; selecting a backup electronic class sign with high network speed and low data transmission volume helps to maximize the utilization of network resources and avoid unnecessary network congestion and resource waste; higher network speed and less data transmission volume means that users can obtain the required information more quickly, thereby improving user experience and work efficiency; by selecting a backup electronic class sign with excellent performance, the additional costs that may be incurred due to improper use of network resources can be effectively reduced, thereby achieving cost savings; considering that in actual situations, network speed and data transmission volume may change over time, the evaluation should be as close to the actual usage data as possible, so the data at the moment of performing the scoring calculation is selected to obtain an accurate evaluation of the performance of the backup electronic class sign.

[0072] Therefore, considering the resource availability of backup electronic class signs, especially the factors of network speed and data transmission volume, has a significant beneficial effect on improving the efficiency of the overall system, user experience and cost savings.

[0073] One embodiment of the present invention is an Internet of Things intelligent integrated multimedia control method, which compares the class schedule information of all electronic class signs corresponding to the time period. When it is found that there are no classes within the preset time period of the corresponding time period, the main power supply, doors and windows, air conditioner and face recognition system of the corresponding classroom are turned off; otherwise, they are turned on, including:

[0074] Compare the class schedule information of the electronic class board corresponding to the time period within the preset comparison time period;

[0075] When it is found that there is no class within the preset time period of the corresponding time period and the infrared sensor in the classroom detects that there is no one in the classroom or there is no class but there is someone in the classroom or there is a class within the preset time period of the corresponding time period, the Zigbee communication protocol is used to send corresponding control signals to the power supply, doors and windows, air conditioning, multimedia and monitoring systems in the classroom;

[0076] After receiving the control signal, the corresponding operations are performed on the classroom's main power supply, doors and windows, air conditioning, multimedia and face recognition system.

[0077] Assume that 8:00 am to 12:00 pm is the preset time period for one class, and 1:00 pm to 5:00 pm is the preset time period for another class.

[0078] Ten minutes before 8:00 AM, if the system detects that there are no classes and no classes scheduled, it will control the corresponding devices via the Zigbee communication protocol, such as turning off the air conditioner, multimedia devices, and closing the windows.

[0079] There is no class but there is someone in the classroom or there is a class within the preset time period of the corresponding time period: If someone is detected entering the classroom 10 minutes before 8:00 am, but there is no class scheduled at this time, the system will not perform any operation. If it is detected 10 minutes before 8:00 am that there is a class between 8:00 and 12:00 and there is no one in the classroom, then the system will control the corresponding devices through the Zigbee communication protocol, such as turning on the air conditioner and multimedia devices.

[0080] The working principle of the above technical solution is as follows: the system will compare the course information of the current time period with the preset time period to determine whether there are any courses scheduled at present; it will detect whether there are people in the classroom through infrared sensors, and then combine the class schedule information to determine whether the main power supply, doors and windows, air conditioning, multimedia and monitoring systems in the classroom need to be controlled; when encountering a situation that meets the conditions, the system will use the Zigbee communication protocol to send corresponding control signals to the relevant equipment in the classroom; after receiving the control signal, the main power supply, doors and windows, air conditioning, multimedia and face recognition system in the classroom will perform corresponding operations, such as turning on or off the equipment.

[0081] The effects of the above technical solution are as follows: through the intelligent control system, the equipment status in the classroom is automatically adjusted according to actual needs, effectively reducing energy waste; the equipment in the classroom can be intelligently controlled according to actual needs, providing students and teachers with a more comfortable learning environment; it reduces the manual intervention of maintenance personnel in the status of classroom equipment, reducing management costs; classroom resource optimization: it can better optimize the use of classroom resources, ensuring that equipment is turned on when needed and automatically turned off when idle, improving resource utilization efficiency. In summary, this solution improves the utilization efficiency of classroom equipment through intelligent control and automated management, while also providing teachers and students with a better learning and teaching environment.

[0082] One embodiment of the present invention provides an IoT intelligent integrated multimedia control method. Upon receiving a control signal, the method performs corresponding operations on the classroom's main power supply, doors and windows, air conditioning, multimedia, and facial recognition systems, including:

[0083] After receiving the shutdown control signal, the main power supply, doors and windows, air conditioning multimedia and face recognition system of the corresponding classroom will be shut down;

[0084] After receiving the open control signal, the main power supply, doors and windows, air conditioning multimedia and face recognition system of the corresponding classroom will be turned on. The electronic class board of the corresponding classroom will send a message to the electronic device of the teacher through the local area network protocol. The teacher will send the courseware to the electronic class board. The electronic class board will send the courseware to the multimedia in the classroom through the Zigbee communication protocol. After receiving the courseware, the multimedia will place the courseware on the desktop.

[0085] If the multimedia system in a scheduled classroom is damaged, the best backup classroom will be selected from available classrooms with a capacity equal to or greater than that of the classroom being replaced based on the backup classroom scoring model. A notification message will be sent to the electronic devices of the students and teachers who will be attending the class. The backup classroom scoring model is as follows:

[0086] Among them, Score1 is the first score, Score 2 is the second score, w1, w4 and w5 are weight coefficients, X i is the commuting distance between the spare classroom and the classroom being replaced, C m is the number of people that the spare classroom can accommodate, C n The number of people that can be accommodated in the classroom being replaced.

[0087] The working principle of the above technical solution is: when a control signal of closing or opening is received, the main power supply, doors and windows, air conditioning, multimedia and face recognition system in the corresponding classroom will perform corresponding operations; when the courseware needs to be updated, the electronic class board sends a message to the electronic device of the teacher through the local area network protocol, and the teacher sends the courseware to the electronic class board. Then the electronic class board sends the courseware to the multimedia in the classroom through the Zigbee communication protocol. After receiving it, the multimedia device presents it on the desktop for teaching use; if the multimedia equipment in the scheduled classroom is damaged, the system will select the best backup classroom from the idle classrooms with a capacity greater than or equal to the capacity of the replaced classroom based on the backup classroom scoring model, and notify the relevant personnel.

[0088] The above technical solution achieves the following effects: By transmitting messages from electronic class signs to teachers' electronic devices, rapid courseware updates are achieved. Furthermore, through the Zigbee communication protocol, courseware can be quickly transmitted to classroom multimedia devices and presented on the desktop, improving teaching efficiency. When multimedia equipment in a scheduled classroom fails, the system can quickly and intelligently select the best backup classroom and notify relevant users to ensure normal teaching. Using a backup classroom scoring model, the system can rationally select backup classrooms, reducing teaching interruptions caused by equipment failures and thereby optimizing classroom resource utilization to the greatest extent possible. The automated process for fault handling and backup classroom selection reduces manual intervention and helps lower management costs. Intelligent control of classroom equipment and intelligent selection of backup classrooms improve the stability and reliability of the overall learning environment. This technical solution improves the efficiency and stability of the teaching process through intelligent control and automated fault handling, while also providing a more convenient solution for educational management.

[0089] The backup classroom scoring model takes into account the commuting distance between the backup classroom and the replaced classroom. The closer the distance, the higher the score. The commuting distance takes into account factors such as the path, road and traffic conditions required for teachers and students to actually reach the backup classroom. The straight-line distance only considers the shortest distance between two points, but does not consider the actual movement path. For example, it may be necessary to bypass a building, go through a corridor or stairs, etc. The commuting distance is closer to the actual situation. It takes into account the actual walking or driving path, so it is more suitable for evaluating the selection of backup classrooms. Therefore, the model can help make decisions that are closer to actual needs; the classroom capacity is taken into account. The closer the score is to the capacity of the originally scheduled classroom, the higher the score. This avoids the situation where a small number of students are switching to a large classroom, avoids unnecessary waste of resources, and makes the best possible use of the classroom; the first score considers the electronic class sign. Because students entering the backup classroom need to use the electronic class sign of the backup classroom to sign in, factors such as the network bandwidth of the electronic class sign also need to be considered to improve the response speed of the system and comprehensively improve the user experience.

[0090] One embodiment of the present invention is an IoT intelligent integrated multimedia control method.

At the same time, through the Zigbee communication protocol, courseware can be quickly transmitted to classroom multimedia equipment and presented on the desktop, which improves teaching efficiency; when the multimedia equipment in the scheduling classroom fails, the system can quickly and intelligently select the best backup classroom and notify relevant users to ensure normal teaching; through the backup classroom scoring model, the system can reasonably select backup classrooms to reduce teaching interruptions caused by equipment failures, thereby optimizing the utilization of classroom resources to the greatest extent; the automated process of fault handling and backup classroom selection reduces manual intervention and helps reduce management costs; the intelligent control of equipment in the classroom and the intelligent selection of backup classrooms improve the stability and reliability of the overall learning environment; this technical solution improves through intelligent control and automated fault handling. It improves the efficiency and stability of the teaching process and provides a more convenient solution for education management. The spare classroom scoring model takes into account the distance between the spare classroom and the replaced classroom, which reflects the time and energy required by students and teachers. The comparison of the number of people that the spare classroom can accommodate and the number of people that the replaced classroom can accommodate reflects the capacity of the spare classroom to accommodate the students and teachers of the originally scheduled classes. The closer the number of people is to the capacity of the originally scheduled classroom, the higher the score, which greatly utilizes the spare classroom. The score of the electronic class sign is also taken into account, because students entering the spare classroom need to use the electronic class sign of the spare classroom to sign in. The higher the score of the electronic class sign of the spare classroom, the higher the Score2. The introduction of weights can adjust and weigh different factors according to actual conditions to ensure the flexibility of the system.
