Description

Technical Field

[0001] The present invention relates to the field of intelligent education, and particularly to an intelligent education central control system and a control method thereof. Background Art

[0002] In the traditional teaching environment, devices such as projectors, speakers, teaching computers, and air conditioners all need to be controlled through separate switches or remote controls. Inevitably, a certain amount of time is occupied during the teaching process to control the above-mentioned classroom devices, and the operation is cumbersome and affects teaching efficiency.

[0003] With the development of teaching equipment management technology, in the modern education environment, in order to simplify the operation process of teaching equipment, many schools have introduced education central control systems. Some education central control systems achieve centralized control of teaching equipment through software programs such as mobile terminal APPs, PC terminals, or WEBs. The software programs communicate with the education central control host through the TCP / IP protocol of the network to control the switches of devices such as projectors, speakers, and teaching equipment. However, the above control method is one-to-one and performs poorly in large application scenarios with multiple classrooms, and it is impossible to centrally manage multiple education central control hosts.

[0004] In addition, the existing education central control system and the broadcasting system are two independent devices, and both play specific content through the audio playback device in the classroom, which is prone to signal conflicts between the two or the teacher is constantly harassed by invalid broadcast information during the teaching process, which is not conducive to the efficient progress of teaching.

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention. To describe the present invention in more detail, the intelligent education central control system and its control method provided by the present invention will be specifically described below in conjunction with the drawings.

[0053] Unless otherwise defined, the technical terms or scientific terms used in the disclosure of the present application should have the ordinary meaning understood by those of ordinary skill in the art to which the present invention belongs. The "first", "second" and similar terms used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, the terms such as "a", "one" or "the" do not indicate a quantity limitation, but indicate the existence of at least one. The terms such as "including" or "comprising" mean that the elements or objects appearing before the term cover the elements or objects listed after the term and their equivalents, without excluding other elements or objects. The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms such as "upper", "lower", "left", "right" are only used to represent relative position relationships, and when the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0054] In the traditional teaching environment, teaching projectors, speakers, teaching computer devices, classroom lights, and even air conditioners need to be controlled through separate switches or remote controls, which inevitably takes up a certain amount of teaching time, and the operation process of the above devices is cumbersome and easily affects the teaching efficiency.

[0055] With the development of centralized management of teaching equipment, in the modern teaching environment, to simplify the operation process of teaching equipment, an education central control system is introduced. The education central control system can centrally control the above-mentioned teaching equipment in the classroom (including but not limited to teaching computers, projectors, and speakers) through instructions.

[0056] Both the intelligent education central control system and the broadcast system are communicatively connected to the audio playback devices in the classroom (such as speakers and student terminal devices) to play teaching content or broadcast information; however, the intelligent playback central control system and the broadcast system are two independent systems, and signal conflicts are likely to occur between them. For example, when the audio playback device receives both teaching content and broadcast information at the same time, it cannot determine which specific information to play, or the broadcast system is set to the highest playback level, but the broadcast information is irrelevant to the people in the classroom or of low importance, resulting in the teaching process being continuously harassed by invalid broadcast information, which is not conducive to the efficient progress of teaching.

[0057] In response to this, the present invention provides an intelligent education central control system, which links the education central control system with the broadcast system with the education central control host as the end of the campus broadcast system, and is provided with a centralized control platform to uniformly manage all education central control systems on campus, improve the management efficiency of the intelligent education central control, and broadcast the teaching broadcast content and the broadcast content in combination with the actual situation in the classroom, reducing the interruption of the teaching process by invalid information. In combination with the attached Figure 1 and attached Figure 2 The intelligent education central control system of the embodiment of the present application will be described in detail.

[0058] The intelligent education central control system of this embodiment includes a campus broadcast system, a centralized control platform, a number of education central control hosts, a number of camera modules, a number of audio processing modules, and a number of audio collection modules; among them,

[0059] The campus broadcast system is used to send broadcast information to the education central control host;

[0060] The centralized control platform is used to centrally manage the education central control host according to the class scheduling information or teaching plan of the classroom;

[0061] The camera module is communicatively connected to the education central control host, and is used to obtain the personnel information in the classroom and send it to the education central control host;

[0062] The audio collection module is connected to the audio processing module, and is used to collect the audio information in the classroom and send the audio information in the classroom to the audio processing module;

[0063] The audio processing module is communicatively connected to the education central control host, and is used to extract audio features from the received audio information in the classroom and send the audio features to the education central control host;

[0064] The educational central control host selects to play broadcast information or teaching information by combining the classroom personnel information and audio features.

[0065] It should be noted that in this embodiment, the educational central control host, the centralized control platform, and the campus broadcast system can be computer devices, and the computer devices can be at least one of devices such as desktop computers, portable computers, laptop computers, mainframe computers, and tablet computers. The educational central control host is fixedly installed in any number of classrooms on campus, and the educational central control host is used to send operation instructions to teaching equipment in the classroom. The teaching equipment in the classroom includes but is not limited to projectors, teaching computers, student computers, student tablets, classroom lights, classroom speakers, and classroom air conditioners. The educational central control host and the centralized control platform are communicatively connected using asynchronous network I / O technology to improve the concurrent processing ability of the centralized control platform and enable centralized monitoring and management of multiple educational central control hosts in large application scenarios.

[0066] The camera module can be an AI camera module or a CCD module configured with personnel information recognition. The classroom personnel information sent by the camera module includes but is not limited to the number of people in the classroom, the positions of people in the classroom, and the activity information of people in the classroom. The activity information of people in the classroom can be the activity status information of people in the classroom, such as people in the classroom sitting on their seats, people in the classroom walking around, people in the classroom leaving, etc.

[0067] The audio acquisition module includes but is not limited to microphones and audio sensors, and is used to acquire classroom audio information.

[0068] Specifically, the above classroom personnel information includes the number of people in the classroom, the positions of people in the classroom, and the activity information of people in the classroom;

[0069] The audio features include the classroom volume, frequency characteristics, and signal-to-noise ratio.

[0070] Specifically, it can be comprehensively judged whether the classroom is in a class state through the above classroom personnel information; it can be determined whether it is in a teacher teaching state by comparing the above audio features with the teacher's audio features corresponding to the teaching information.

[0071] Furthermore, the intelligent educational central control system further includes several administrator devices, and the administrator devices are communicatively connected to the centralized control platform and are used to receive alarm information about the abnormality of at least one educational central control host.

[0072] Furthermore, the intelligent educational central control system further includes several mobile terminals, and each mobile terminal is communicatively connected to one or more educational central control hosts and is used to remotely control the educational central control host through user authentication.

[0073] Based on the above intelligent education central control system, this embodiment also proposes a control method for the intelligent education central control system. This control method is applied to any one of the education central control hosts placed in each classroom in the intelligent education central control system, and in combination with the attached Figure 3 Schematic diagram of the control method of the intelligent education central control system shown, the steps of this control method are described as follows:

[0074] Step S101, obtain the personnel information in the classroom sent by the camera module, the audio characteristics sent by the audio processing module, the broadcast information sent by the broadcast system, and the teaching information sent by the mobile terminal.

[0075] Specifically, the camera module can be an AI camera module or a CCD module configured with personnel information recognition. The personnel information in the classroom sent by the camera module includes but is not limited to the number of personnel in the classroom, the location of personnel in the classroom, and the activity information of personnel in the classroom. The activity information of personnel in the classroom can be the activity status information of personnel in the classroom, such as personnel in the classroom sitting on the seat, personnel in the classroom walking, personnel in the classroom leaving, etc.

[0076] The audio characteristics include but are not limited to the volume in the classroom, frequency characteristics, and signal-to-noise ratio. The audio characteristics are used to describe the audio characteristics in the classroom, and whether the classroom is in the state of the teacher giving a lecture, whether it is in the state of self-study or test, whether it is in the state of free activity, etc. can be determined according to the audio characteristics.

[0077] The broadcast information sent by the broadcast system includes various campus broadcast information, including but not limited to radio broadcasts, campus announcements, and conference broadcasts. In this embodiment, the broadcast information carries a priority label, which is set according to the urgency of the broadcast information. When the urgency of the broadcast information is higher, the priority label is larger.

[0078] The teaching information is the specific teaching information sent by the mobile terminal at the teacher's end to the education central control host.

[0079] Step S102, determine whether the classroom is a broadcast target classroom according to the personnel information in the classroom and the audio characteristics.

[0080] After the education central control host receives the above information, it first needs to determine whether the classroom where the education central control host is located is a broadcast target classroom. For example, if there are no students or teachers in class or activities in the classroom where the education central control host is located, this classroom is not a broadcast target classroom. At this time, the broadcast information can be directly deleted to reduce the operation of invalid broadcasts.

[0081] Specifically, if the number of personnel in the classroom is zero, or the volume in the classroom in the audio characteristics is lower than the preset threshold, it is determined that this classroom is not a broadcast target classroom.

[0082] Further, considering that some broadcast information is targeted, for example, only students in certain grades or only personnel in certain areas need to be notified. At this time, in addition to considering the number of people in the classroom and the audio characteristics, it is also necessary to combine the characteristics of the people in the classroom and the target group of the broadcast information to determine whether the classroom is a target classroom for broadcasting. Specifically:

[0083] If the number of people in the classroom is not zero and the volume in the classroom in the audio characteristics is greater than the preset threshold, obtain whether the characteristics of the people in the classroom are consistent with the target group of the broadcast information. If the characteristics of the people in the classroom are consistent with the target group of the broadcast information, then determine that the classroom is a target classroom for broadcasting.

[0084] The characteristics of the people in the classroom include but are not limited to the grades of the students in the classroom and the location information of the classroom. The target group of the broadcast information can be determined by a preset keyword extraction module. The keyword extraction module can determine which grade of students (such as first-year students) or which area of students (such as students in Building 1 of the teaching building) the broadcast information needs to be received by identifying the broadcast information.

[0085] Step S103, if the classroom is a target classroom for broadcasting, determine whether the priority label of the broadcast information is greater than the priority threshold corresponding to the teaching information.

[0086] Specifically, the priority label carried by the broadcast information is set according to the urgency of the broadcast information. In this embodiment, different priority thresholds are set according to different teaching information. The priority thresholds corresponding to the teaching information include a first priority threshold, a second priority threshold, and a third priority threshold, where the first priority threshold is less than the second priority threshold, and the second priority threshold is less than the third priority threshold.

[0087] The process of determining the priority threshold corresponding to the teaching information includes the following steps: obtain the teaching label information included in the teaching information; determine the priority threshold corresponding to the teaching information according to the teaching label information. Among them, the teaching label information includes but is not limited to self-study class / test class, general education course, professional course / examination; when the teaching label information is "self-study class / test class", the teaching information corresponds to the first priority threshold, and at this time, the insertion of the broadcast information will not have too much impact on the class; when the teaching label information is "general education course", the teaching information corresponds to the second priority threshold, and at this time, it is not recommended that broadcast information with low urgency disturb the class; when the teaching label information is "professional course / examination", the teaching information corresponds to the third priority threshold, and at this time, only broadcast information with a high degree of urgency can be inserted.

[0088] Step S104, if the priority label of the broadcast information is greater than the priority threshold corresponding to the teaching information, play the broadcast information.

[0089] Specifically, when the priority label of the broadcast information is greater than the priority threshold corresponding to the teaching information, it indicates that the urgency of the broadcast information is allowed to interrupt the classroom teaching process. At this time, the education central control host selects to insert and play the broadcast information.

[0090] Furthermore, in this embodiment, in addition to comparing the priority label of the broadcast information with the priority threshold corresponding to the teaching information, considering that some emergency notifications involve the evacuation of personnel, which is irrelevant to whether it is in classroom teaching and the importance of classroom teaching at this time. In this embodiment, a preset emergency priority is set to address emergency broadcast notifications such as emergency personnel evacuation, fire alarm notification, air defense warning, tsunami warning, earthquake warning, etc. Specifically:

[0091] If the priority label of the broadcast information is greater than the preset emergency priority, stop receiving audio input information other than the broadcast information, and play the broadcast information after amplification processing.

[0092] Specifically, when the priority label of the broadcast information is greater than the preset emergency priority, the education central control host also needs to perform amplification processing before playing the broadcast information to ensure that each person can receive the emergency broadcast notification as much as possible and improve the notification efficiency of the emergency broadcast.

[0093] Step S105, if the priority label of the broadcast information is less than the priority threshold corresponding to the teaching information, determine whether the personnel information and audio characteristics in the classroom meet the preset suppression conditions.

[0094] Step S106, if the personnel information and audio characteristics in the classroom meet the preset suppression conditions, play the teaching information.

[0095] Specifically, when the personnel information and audio characteristics in the classroom meet the preset suppression conditions, it indicates that the broadcast information is not convenient to disturb the classroom teaching process. At this time, the education central control host plays the teaching content. However, considering that the broadcast information also needs to be received by the personnel in the classroom, different processing methods can be selected according to the specific priority label of the broadcast information at this time, including the following steps:

[0096] Step S201, if the personnel information and audio characteristics in the classroom meet the preset suppression conditions, and the priority label of the broadcast information is greater than the lowest priority, send an insertion request to the mobile terminal.

[0097] Step S202, if the consent insertion instruction feedback from the mobile terminal is received, play the broadcast information when the volume in the classroom is lower than the teaching volume.

[0098] Step S203, if the personnel information and audio features in the classroom meet the preset suppression conditions, and the priority label of the broadcast information is less than the lowest priority, obtain the stop timestamp of the teaching information.

[0099] Step S204, place the broadcast information combined with the stop timestamp in the sequence to be played.

[0100] It should be noted that the above-mentioned lowest priority is the lowest standard for whether the broadcast information needs to occupy classroom time for playing. If the priority label of the broadcast information is less than the lowest priority, it means that the broadcast information does not need to occupy classroom time for playing, and further obtain the stop timestamp of the teaching information corresponding to this classroom, and place the broadcast information in the sequence to be played in combination with this stop timestamp, so that the broadcast information can be played after the teaching information is played. If the priority label of the broadcast information is greater than the lowest priority, but the personnel information and audio features that the broadcast information needs to be played in the classroom both meet the suppression conditions, it also means that the broadcast information can occupy classroom time for playing, but it needs to obtain the permission of the classroom teacher. Therefore, a plug-in request is sent to the mobile terminal equipped for the teacher, and the broadcast information is inserted after obtaining the permission.

[0101] In addition, considering that the priority level of the existing campus broadcast is preset and fixed, however, there may be differences in the response time of students after receiving various campus broadcasts. There may be some campus broadcasts with a relatively high priority level, and students may not respond quickly after receiving them. That is to say, some campus broadcasts with a relatively high priority level may not match the preset emergency level; while some campus broadcasts with a relatively low priority level may have a shorter response time than expected after students receive them. That is to say, some campus broadcasts with a relatively low priority level may also not match the preset emergency level. Based on this, the present application also proposes to dynamically adjust the priority level of this type of broadcast information according to whether the response of the campus broadcast receiver is timely, so that the priority level setting of the broadcast information is more in line with the actual situation. The specific steps are as follows:

[0102] Step S301, after playing the broadcast message, send a personnel reaction collection instruction to the camera module, which is used to collect the personnel reaction information of the personnel in the classroom after receiving the broadcast information through the camera module.

[0103] Specifically, in this embodiment, it can be set that after the education central control host plays the broadcast message, after a set time interval (for example, 30s after playing the broadcast message), send a personnel reaction collection instruction to the camera module, and this personnel reaction collection instruction is used to collect the personnel reaction information of the personnel in the classroom after receiving the broadcast information through the camera module.

[0104] Step S302: Compare the in-class personnel information before the in-class personnel receive the broadcast message and the personnel response information after receiving the broadcast message.

[0105] Step S303: If the difference degree between the in-class personnel information and the personnel response information is less than the response threshold, lower the priority label of the type to which the broadcast message belongs.

[0106] Specifically, to compare whether the in-class personnel make obvious responses before and after receiving the broadcast message, the specific personnel information of the in-class personnel before and after receiving the broadcast message can be compared. For example, the number of in-class personnel before and after receiving the broadcast message, the action differences or position differences of the same personnel, etc. Combining the number of in-class personnel, when the action differences or position differences of the same personnel exceed the activity threshold and the number of personnel exceeding the activity threshold exceeds the set personnel number threshold, it can be regarded that the difference degree between the in-class personnel information and the personnel response information exceeds the response threshold. At this time, it can be considered to increase the priority label of the type to which the broadcast message belongs. On the contrary, when the action differences or position differences of the same personnel exceed the activity threshold and the number of personnel exceeding the activity threshold is lower than the minimum response personnel number, it can be regarded that the difference degree between the in-class personnel information and the personnel response information is less than the response threshold. At this time, the priority label of the type to which the broadcast message belongs should be lowered, so as to reduce the urgency of subsequent broadcast messages of the same type and reduce the interference of invalid broadcast messages on the classroom. It should be noted that in this embodiment, the activity threshold, the set personnel number threshold, and the minimum response personnel number are set according to the priority label corresponding to the broadcast message, and the above-mentioned activity threshold, set personnel number threshold, and minimum response personnel number corresponding to different priority labels are different.

[0107] Furthermore, this embodiment also includes managing the operation status data of the education central control host. The education central control host communicates with the centralized control platform in real time using the TCP / IP protocol and sends the operation status data of the education central control host to the centralized control platform at a preset time interval. If the centralized control platform receives any operation status data of any education central control host that meets the abnormal alarm condition, an alarm message will be generated and sent to the administrator device through the SIM card short message sending module, so as to remind the administrator to repair or maintain the education central control host with abnormalities.

[0108] Even further, if the centralized control platform detects that the operation status data of the same education central control host meets the abnormal alarm condition and reaches the preset abnormal threshold, in addition to sending an alarm message to the administrator device, the centralized control platform also needs to send an instruction to increase the operation status data collection frequency to the education central control host, shorten the time interval for the education central control host to send the operation status data to the centralized control platform, and strengthen the monitoring of the education central control host.

[0109] In addition, the intelligent education central control system of this embodiment is also equipped with a number of mobile terminals, and each mobile terminal is communicatively connected to one or more education central control hosts for remotely controlling the education central control host through user authentication.

[0110] Specifically, the mobile terminal can be a mobile terminal equipped for teachers, including but not limited to smart phones, tablets, and laptops. Teachers log in on the mobile side according to the assigned account and password, and send instructions to the education central control host through the mobile side for remote control. Considering the mobility of the classrooms where teachers have classes, in this embodiment, the mobile terminals equipped for teachers are communicatively connected to one or more education central control hosts. Considering the permissions of the mobile terminal for the education central control host, each time the mobile terminal establishes a communication connection with the education central control host to achieve remote control, the mobile terminal needs to perform user authentication. If the user authentication fails (for example, the account and password entered on the mobile terminal are inconsistent with the pre-stored account and password in the database), the remote control stage cannot be entered.

[0111] Furthermore, this embodiment also includes the execution of scheduled tasks. The centralized control platform is provided with a memory for storing scheduled tasks. The scheduled tasks include task content, task start time, and the education central control host specified for task execution. After receiving the scheduled storage task, the centralized control platform generates a task sequence in combination with the task start time and the education central control host specified for task execution, and sends the scheduled task to the education central control host before the task start time, so that the specified education central control host can execute the task content of the scheduled task at the task start time.

[0112] Thus, in the control method of the intelligent education central control system provided by this embodiment, after the education central control host in the classroom receives the broadcast information and teaching information, it first verifies whether the classroom is the target classroom of the broadcast confidence, and then combines the camera module, audio acquisition module, and audio processing module set inside the classroom to determine the current teaching state of the classroom, compares the priority label of the broadcast information with the priority threshold corresponding to the teaching information, and judges whether the broadcast information can interrupt the teaching in the classroom. While meeting the requirements of broadcast message notification, it minimizes unnecessary interference to classroom teaching, not only ensuring the efficiency of broadcast message notification, but also preventing the broadcast message notification from causing undifferentiated interference to classroom teaching, improving the efficiency of broadcast information notification and ensuring the normal progress of classroom teaching.

[0113] Furthermore, this embodiment also processes broadcast messages that unnecessarily interfere with classroom teaching in combination with the personnel information and audio characteristics in the classroom, allowing broadcast messages with a lower level of urgency to be quickly inserted after obtaining the consent of the teacher or management personnel, and delaying broadcast messages with such a low level of urgency that they are not necessary to interfere with classroom teaching until after class, which not only ensures the effective transmission of broadcast information but also reduces interference to classroom teaching.

[0114] In addition, this embodiment also determines whether the reaction of a person in the classroom conforms to the reaction degree that should be had by the priority of the broadcast message by combining the difference degree before and after the person in the classroom receives the broadcast message, and dynamically adjusts the priority of the broadcast message, so that the broadcast message inserted in the classroom has higher efficiency and reduces unnecessary interruption to classroom teaching.
