Description

Technical Field

[0001] The present invention relates to the field of big data education technology, and in particular to a children's education control system based on big data. Background Art

[0002] With the development of society, more and more people are paying close attention to children's education and learning during preschool education. Guardians are also needed to grow up with their children. However, guardians often do not have enough time to accompany their children in their learning and growth, nor do they know the specific content and focus of their children's learning. Currently, there are some readers on the market that can learn the content of books by clicking on the content of the books with a touch pen, but the voice of these readers is often too mechanical, which makes children feel too boring and dislike learning knowledge. Big data is the ability to obtain relevant data through some software tools, conduct distributed mining on massive data, and analyze user behavior, so as to reasonably use data to handle things; Patent No. 201910249581.5 involves the use of smart books. Although the role of smart books is not specifically mentioned in the article, using smart books for every book is too wasteful of materials and too restrictive, and cannot fully improve the role of explaining to children. Therefore, a smart book cover is set up in this article. By placing the book on the smart book cover, the content of the book can be obtained and explained to children, and the explanation is vivid and interesting. Summary of the Invention

[0003] The purpose of the present invention is to provide a children's education control system based on big data to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a big data-based children's education control system, which includes a smart bracelet, a control terminal, a photo detection module, a focusing projection module, a placement position adaptive adjustment module, an intelligent book cover reading module, a text information acquisition module, a page thickness reading module, a child's sight capture module, an intelligent voice playback explanation module, a voice stop explanation module, a data recording module, a child's learning status analysis module, a testing module, an anti-cheating module, and a task reading module; The smart bracelet is worn on the child's wristband and is used to remind the child and provide a medium for the child to read books, so that the child can read books without the accompaniment of parents, saving parents' time; the control end is connected to the smart bracelet, and the control end includes a signal receiving module and a signal sending module, the signal receiving module is used to receive information sent by the smart bracelet, and the signal sending module is used to send instructions to other modules based on the information stored in the smart bracelet; the photo analysis module is used to analyze the content of the photos taken by the camera and transmit the captured content to the smart bracelet through the control end; the focused projection module is used to guide the child to read books by projecting a holographic image above the desk, and the generated holographic image is reflected by the holographic projection film attached to the desk, so that the child can read the information on the book through the holographic projection; the placement position adaptive adjustment module is used to send an instruction to the control end when the book placed in the smart book cover reading module deviates from the sensing area, issue a prompt and automatically adjust the position of the book, so that the child can hear the explanation sound, and avoid being unable to read the content of the book due to the wrong placement of the book; the smart book cover reading module is used to The smart wristband can explain the children's books on the smart book cover to the children, so that the children can understand the knowledge in the books without the need for guardians to supervise and explain to the children; the text information acquisition module acquires the text information of the current page of the book opened on the smart book cover reading module through the photo detection module, and sends the text information to the smart wristband through the information receiving module, so that the smart wristband can understand the information of the book and display the text information to the children; the page thickness reading module is used to determine the page number of the current page based on the thickness of the currently opened book and verify the content of the current page through the text information acquisition module to determine whether the content of the currently displayed page is the same as that of the page displayed by the smart wristband; the child's sight capture module is used to capture the specific line number of the currently opened and displayed page of the child's sight and when it is detected that the current child's sight stay time exceeds a first preset value, it can analyze the content that the child is interested in and send the file information to the smart wristband through the text information acquisition module, instead of playing the content of the current page step by step, which reduces the fun; the intelligent voice playback and explanation module is connected to the child's sight capture module and the voice stop explanation module, and sends the text content to the intelligent voice playback and explanation module for voice explanation;When the voice explanation stop module detects that the child's gaze is not focused on the holographic image and the child's gaze has been away for more than a second preset time, it sends a command to the smart bracelet via the control terminal to stop the currently playing voice. The data recording module is used to save the records of what the child has read and what he or she has not read, so that the child can continue to read the fragments that he or she did not finish reading last time and consolidate the child's knowledge. The child learning status analysis module is used to identify the child's identity based on the child's different voice and tone, and review the learned content based on the child's identity, so that the child can review the learned content and learn new things. The testing module is used to test the content learned by different children to determine whether the child is learning seriously. The anti-cheating module is used to capture the child's gaze during the test to determine whether the child's gaze is in the non-test area, and selectively block the part of the gaze in the non-test area to prevent the child from viewing the learned content and cheating, which would have a negative impact on the child's future learning and life and may cause the child to have opportunistic thoughts. The task reading module is used to send the guardian's instruction on the content to the smart bracelet via the control terminal to determine whether the child has completed the task required by the guardian.

[0005] Furthermore, the intelligent book cover reading module includes a book cover, a baffle is installed on one side directly below the book cover, and a plurality of rolling balls are set in the center of the book cover except for the sensing area. The rolling balls are embedded in the book cover and can be raised and lowered. The book is moved toward the sensing area by the rotation of the rolling balls. When the right top corner of the book completely coincides with one side of the right top corner of the sensing area, a coincidence signal is sent to the placement position adaptive adjustment module through the control end, and the rolling balls descend until they are parallel to the surface of the book cover. The current page needs to be shown to the child. The four top corners of the sensing area are set based on the position coordinates of the smart book cover as W={(x1,y1),(x2,y2),(x3,y3),(x4,y4)}. When the sensing area detects that the text content of the book is incomplete, it sends a signal to the control end to start the rolling ball to push the current book to move; When it is detected that the book area S is less than or equal to the sensing area, the leftmost position coordinates of the top corner of the book that is not in the sensing area and the rightmost position coordinates of the top corner of the book outside the sensing area are set to (a1, b1) and (a2, b2). , M refers to the minimum distance that the left top corner of the book moves to the sensing area, , L refers to the distance between the leftmost and rightmost sides of the book, and the ball is rolled and the moving distance is ML; When it is detected that the area S of the book is larger than the area of the induction region, calculate the distance Y between the leftmost end and the rightmost end of the text on the current page of the book. When it is detected that Y < L, rotate the rolling sphere to completely move Y into the induction region. When it is detected that Y > L, rotate the rolling sphere to move towards the induction region at a certain speed in real time.

[0006] Further, set the speed of the current rolling sphere moving towards the induction region as V1, such that , refers to the speed of the intelligent voice playback and explanation module. When the child selects to double-play the current explanation content, the speed V3 of the current rolling sphere moving towards the induction region needs to be updated in a timely manner, such that . When the detected speed , the intelligent voice playback and explanation module cannot obtain the content behind the book page in a timely manner. When the speed is , when the text information is moving, the text information can be photographed and saved, and a current record can be made to explain to the child.

[0007] Further, through the page number and thickness reading module, the book is placed in the inner area above the baffle. A thickness sensor is installed below the baffle, and one side below the baffle is hinged to the first cross plate. The cross plate is connected by a second cross plate and a third cross plate. The first cross plate is arranged to be liftable. The same side of the second cross plate and the third cross plate is hinged to the first cross plate, and the other side of the second cross plate and the third cross plate enables the thickness of the book to be measured through the lifting of the first cross plate; Judge whether the measured values A and B on the left and right sides of the second cross plate and the third cross plate are the same through the thickness sensor. When it is detected that A = B, it means that the currently opened page is the middle page. When it is detected that A > B, it means that the currently opened page is the rear part area. When it is detected that A < B, it means that the currently opened page is the front part area; When it is detected that the area S of the book is less than or equal to the area of the induction region, judge the current page number within the range of the above page numbers, and send the page number to the smart bracelet through the control end. The smart bracelet sends it to the intelligent voice playback and explanation module and the voice stop explanation module through the information sending end; thereby determining the currently flipped page number; When it is detected that the book area S is larger than the area of ​​the sensing area, the page number of the current book is checked by the fragment text content displayed on the current page, the text content in the current book is set to P, and the text content saved in the smart bracelet is set to O. According to the text content P, the fragment vector keyword D and the text content O are selected for comparison, and the vector with higher frequency is judged. When the cosine similarity is judged that the current result is close to 1, it means that the current similarity is high and the degree of consistency of the fragment text content is high. The instruction is sent to the intelligent voice playback explanation module through the control end for playback. When the result is detected to be far from 1, it means that the current similarity is low and the degree of consistency of the fragment text content is low, and other fragment contents need to be re-detected.

[0008] The child's gaze capture module identifies the text content currently displayed in the sensing area and determines the specific location of the content currently viewed by the child's pupil by the intersection of the child's pupil focal point and the coordinates of the holographic image. When the holographic image content is detected, a command is sent to the intelligent voice playback and explanation module through the control terminal to show the child the current section of the playing page until the intelligent voice playback and explanation module finishes explaining the content of the current page. Regardless of whether the child's pupil is currently in the field of view of the intelligent voice playback and explanation module, the explanation of the current content will not be terminated.

[0009] Furthermore, through the test module, the smart bracelet saves the content that the child has learned and tests the content that the child has learned. The child's test area is based on the area of ​​the holographic image (i1*j1). When it is detected that the focus of the child's pupil is within the test area, it means that the child's attitude during the test is good; When it is detected that the child's pupil is focused outside the test area, and when it is detected that the child's pupil is focused in the learning area, where the learning area is based on the holographic image area of ​​(i2*j2), the information is sent to the smart bracelet through the control end, and the area where the learning area is located is blocked to prevent the child from cheating, indicating that the child's test attitude is poor.

[0010] Furthermore, the intelligent voice playback explanation module includes a timbre data storage module and a timbre recognition control module. The timbre recognition control module is used to jump to the content that the child last learned according to the saved child's timbre. The timbre data storage module is used to recognize and record the timbre of the smart bracelet. The data recording module records and saves the tones with higher frequencies, issues commands to the smart bracelet and sets tasks through the saved tones, sets the guardian's tone as the first tone and the child's tone as the second tone. The authority of the first tone is higher than that of the second tone, and the second tone cannot change the commands issued by the first tone.

[0011] The children's learning includes the following steps: Z01: Place a children's book in the intelligent book cover reading module. When it detects that the children's book is tilted, it sends a command to the placement position adaptive adjustment module through the control terminal to adjust the position of the book until the book is completely within the sensing area; Z02: Get the page number of the current page, and send the instruction to the intelligent voice playback explanation module for explanation according to the current analyzed page number; Z03: Obtain the position of the child's pupil on the holographic image, and explain the content to the child based on the segment where the child's gaze is located after the previous segment is explained; Z04: According to the learning content assigned by the task reading module, the child is tested based on what he / she has learned, and the position of the child's gaze during the test is judged to determine whether there is any cheating behavior, and the child's behavior is sent to the smart bracelet through the control terminal.

[0012] Compared with the prior art, the present invention has the following beneficial effects: A smart book cover is set up, and any children's book can be placed on the smart book cover. The range of children's books is no longer limited, and any book can be explained to children. The smart book cover can also display the currently played page number through the set baffle, so that the intelligent voice playback and explanation module can understand whether there is an error in the currently played content. When children place books on the smart book cover, the intelligent voice playback and explanation module cannot obtain the content on the smart book cover. Therefore, it is necessary to set a liftable rolling ball on the smart book cover so that books in the offset sensing area can be read, and the complete book content can be explained to children. An intelligent voice explanation and playback module is set up to intelligently explain to children by imitating the first tone, which improves the degree to which children listen attentively, making children feel friendly, lively and interesting when listening to the class.

The data recording module is used to save the records of what the child has read and what he or she has not read, so that the child can continue to read the fragments that he or she did not finish reading last time and consolidate the child's knowledge.

The task reading module is used to send the guardian's instruction on the content to the smart bracelet via the control terminal to determine whether the child has completed the task required by the guardian.

[0016] The intelligent book cover reading module includes a book cover, a baffle is installed on one side directly below the book cover, and a plurality of rolling balls are set in the center of the book cover except for the sensing area 3. The rolling balls are embedded in the book cover and can be raised and lowered. The book is moved toward the sensing area 3 by the rotation of the rolling balls. When the right top corner of the book completely coincides with one side of the right top corner of the sensing area 3, a coincidence signal is sent to the placement position adaptive adjustment module via the control end, and the rolling balls descend until they are parallel to the surface of the book cover. The current page needs to be shown to the child. The four top corners of the sensing area 3 are set to the position coordinate set W={(x1,y1),(x2,y2),(x3,y3),(x4,y4)} based on the smart book cover. When the sensing area 3 detects that the text content of the book is incomplete, it sends a signal to the control end to start the rolling ball to push the current book to move; When it is detected that the book area S is less than or equal to the area of ​​the sensing area 3, the leftmost position coordinates of the top corner of the book that is not in the sensing area 3 and the rightmost position coordinates of the top corner of the book outside the sensing area 3 are set to (a1, b1) and (a2, b2). , M refers to the minimum distance that the left top corner of the book moves to the sensing area (3), , L refers to the distance between the leftmost and rightmost sides of the book, and the ball is rolled and the moving distance is ML; When it is detected that the area S of the book is greater than the area of the induction area 3, calculate the distance Y between the leftmost end and the rightmost end of the text on the current page of the book. When it is detected that Y < L, the rolling sphere is rotated to completely move Y into the induction area 3. When it is detected that Y > L, the rolling sphere is rotated in the direction of the induction area 3 and moved in real time at a certain speed.

[0017] Through the set Euclidean distance M and L, it is possible to know the distance that the book outside the induction area 3 needs to be moved to the induction area 3 by the rolling sphere, so as to control the rolling sphere to move the book outside the induction area 3, so that the induction area 3 can read the content within the induction area 3. However, when reading the above content, two situations will occur: the area of the book is smaller than the area of the induction area 3 and the content in the book is larger than the area of the induction area 3. When the first situation occurs, only need to move the book completely into the induction area 3, and the content in the book can be obtained. When the second situation occurs, the text content in the book needs to be displayed in the induction area 3, and the text content in the book can be understood through the holographic image and shown to the user. Therefore, M - L set here can represent the difference in the movement required by the current rolling sphere; The rolling sphere 4 is provided with a lifting device. An arc-shaped groove 5 is installed below the rolling sphere 4, and an electric push rod 6 is installed below the arc-shaped groove 5. The electric push rod 6 pushes the rolling sphere 4 on the arc-shaped groove 5 to move up and down. When it is detected that the book is not in the induction area 3, the electric push rod 6 pushes the rolling sphere 4 to move upward, and the rolling sphere 4 rotates to one side, so that the book can move towards the induction area 3. Since there is no rolling sphere 4 in the induction area 3, when it rolls to the induction area 3, at this time the rolling sphere 4 moves downward, and the book is exactly within the induction area 3.

[0018] Set the speed of the current rolling sphere 4 moving towards the induction area 3 as V₁, so that , refers to the speed of the intelligent voice playback and explanation module. When the child selects to double-play the current explanation content, the speed V₃ of the current rolling sphere 4 moving towards the induction area 3 needs to be updated in time, so that . When the detection speed , the intelligent voice playback and explanation module cannot obtain the content behind the book page in time. When the speed is , when the text information moves, the text information can be photographed and saved and a current record can be made to explain to the child; When the rolling sphere 4 moves the book to one side, there will be a relative speed. When the area of the book is smaller than the area of the induction region 3, it is necessary to move the rolling sphere 4 into the induction region 3 and use the intelligent voice playback and explanation module to explain, so as to obtain the text content. When it is detected that the rolling sphere 4 accelerates to move, it is necessary to control the moving speed so that the speed of the intelligent voice playback is greater than the moving speed of the text information. If it is slower than the moving speed of the text information, the subsequent content of the text information cannot be understood, and the intelligent voice playback and explanation module will stop explaining, which distracts the attention of children.

[0019] Through the page number and thickness reading module 9, the book is placed in the inner area above the baffle. A thickness sensor 9 is installed below the baffle, and one side below the baffle 2 is hinged to the first cross plate 10. The first cross plate 10 is connected by the second cross plate 7 and the third cross plate 8. The first cross plate 10 is arranged to be liftable. The same side of the second cross plate 7 and the third cross plate 8 is hinged to the first cross plate 10, and the other side of the second cross plate 7 and the third cross plate 8 enables the thickness of the book to be measured through the lifting of the first cross plate 10; Judge whether the measured values A and B on the left and right sides of the second cross plate 7 and the third cross plate 8 are the same through the thickness sensor 9. When it is detected that A = B, it means that the currently opened page is the middle page. When it is detected that A > B, it means that the currently opened page is the latter part area. When it is detected that A < B, it means that the currently opened page is the former part area; When it is detected that the area S of the book is less than or equal to the area of the induction region 3, judge the current page number within the above page number range, and send the page number to the smart bracelet through the control terminal. The smart bracelet sends it to the intelligent voice playback and explanation module and the voice stop explanation module through the information sending terminal; thus, the currently turned page number is determined; When it is detected that the area S of the book is greater than the area of the induction region ③, check the current page number of the book through the fragment text content displayed on the current page. Set the text content in the current book as P, and the text content stored in the smart bracelet as O. Select the fragment vector keyword D from the text content P and the fragment vector keyword F from the text content O for comparison, and judge the vector with a higher frequency. When it is judged that the current result is close to 1 through the cosine similarity, it means that the current similarity rate is relatively high and the coincidence degree of the fragment text content is relatively high, and the instruction is sent to the intelligent voice playback and explanation module for playback through the control terminal. When it is detected that the result is far from 1, it means that the current similarity rate is relatively low and the coincidence degree of the fragment text content is relatively low, and other fragment contents need to be detected again; The thickness sensor 9 can detect the thickness of the placed book. By measuring the distance between the left and right sides of the second horizontal plate 7 and the third horizontal plate 8, it can be determined whether the thickness of the left and right sides of the current document is the same, and it can be analyzed whether the current page of the book is on the left or right. This further narrows the range of using cosine similarity to determine text similarity, and increases the accuracy and effectiveness of the search. Because the book is larger than the area of ​​the sensing area 3, the page number of the current page cannot be known. The above method can accurately determine the thickness of the book, and through cosine similarity, it can be analyzed through segment similarity after narrowing the range to determine whether the current content is the same.

[0020] The child's gaze capture module recognizes the text content currently displayed in the sensing area 3 and determines the specific location of the content currently viewed by the child's pupil by the intersection of the child's pupil focal point and the coordinates of the holographic image. When the content of the holographic image is detected, a command is sent to the intelligent voice playback and explanation module through the control terminal to show the child the current section of the playing page until the intelligent voice playback and explanation module finishes explaining the content of the current page. Regardless of whether the child's pupil is currently in the field of view of the intelligent voice playback and explanation module, the explanation of the current content will not be terminated.

[0021] Through the test module, the smart bracelet saves the content that the child has learned and tests the content that the child has learned. The child's test area is based on the area of ​​the holographic image (i1*j1). When the point where the child's pupil is focused is detected within the test area, it means that the child has a good attitude during the test. When it is detected that the child's pupil is focused outside the test area, and at the same time it is detected that the child's pupil is focused in the learning area, where the learning area is based on the holographic image area of ​​(i2*j2), the information is sent to the smart bracelet through the control end, and the area where the learning area is located is blocked to prevent the child from cheating, indicating that the child's test attitude is poor.

[0022] The intelligent voice playback explanation module includes a timbre data storage module and a timbre recognition control module. The timbre recognition control module is used to jump to the content that the child last learned according to the saved child's timbre. The timbre data storage module is used to recognize and record the timbre of the smart bracelet. The data recording module records and saves the timbre with higher frequency, issues commands to the smart bracelet and sets tasks through the saved timbre, sets the guardian's timbre as the first timbre and the child's timbre as the second timbre. The authority of the first timbre is higher than that of the second timbre, and the second timbre cannot change the command issued by the first timbre; When it is detected that the first voice and the second voice are speaking at the same time, control is performed according to the first voice.

[0023] The children's learning includes the following steps: Z01: Place a children's book in the intelligent book cover reading module. When it detects that the children's book is tilted, it sends a command to the placement position adaptive adjustment module through the control terminal to adjust the position of the book until the book is completely within the sensing area 3; Z02: Get the page number of the current page, and send the instruction to the intelligent voice playback explanation module for explanation according to the current analyzed page number; Z03: Obtain the position of the child's pupil on the holographic image, and explain the content to the child based on the segment where the child's gaze is located after the previous segment is explained; Z04: According to the learning content assigned by the task reading module, the child is tested based on what he / she has learned, and the position of the child's gaze during the test is judged to determine whether there is any cheating behavior, and the child's behavior is sent to the smart bracelet through the control terminal.

[0024] Example 1: Assume that there is a set of books. The coordinates of the four corners of the sensing area based on the smart book cover are W = {(20, 40), (90, 40), (20, 100), (90, 100)}. The length and width of the book are 70*50. The area of ​​the detected book is the same as the area of ​​the sensing area. The coordinates of the left corner of the current book and the rightmost corner of the book in the sensing area are (-40, 100) and (10, 100). ; ; Therefore, the rolling ball needs to move 50 degrees toward the sensing area (3); Example 2: In Example 1, when it is detected that the length and width of the book are 90*80, it is detected that the area of ​​the book is larger than the area of ​​the sensing area, and it is detected that the distance between the leftmost end of the text on the current book page and the rightmost end of the text on the same page is Y=80, and Y>L=50, it is necessary to move the book in real time toward the sensing area by rotating the rolling ball.
