Intelligent teaching terminal automatic recording device and use method thereof

Abstract

This invention relates to the field of automatic recording technology, specifically to an automatic recording device for a smart teaching terminal and its usage method. It includes a tripod and a recording device body mounted on the tripod, as well as multiple protective plates mounted on the tripod. A protective assembly, also mounted on the tripod, drives the protective plates to protect the recording device body. Unlike existing technologies, when the recording device is bumped and tipped over, a spring triggers a gear to move, which, through a rotating shaft, removes the fixing of the lead screw and connecting seat, further releasing the protective plates. Then, driven by a torsion spring, the protective plates flip, protecting the recording device body. This ensures that when the recording device body falls, the protective plates contact the ground first, buffering the impact force and preventing direct collision between the recording device body and the ground, thus greatly improving the safety of the recording device body.

Description

Technical Field

[0001] This invention relates to the field of automatic lesson recording technology, specifically to an automatic lesson recording device for a smart teaching terminal and its usage method. Background Technology

[0002] Smart teaching is the inevitable result of school education informatization focusing on teaching, classrooms, and teacher-student activities. It is an intelligent and efficient classroom built using new-generation information technologies such as big data, cloud computing, the Internet of Things, and mobile internet. The emergence of smart classrooms has greatly improved students' learning enthusiasm and initiative, broken the traditional classroom's rote learning approach, made teaching more targeted and efficient, and improved the information literacy of both students and teachers. In the process of smart teaching, teachers use recording devices to record courses into videos for students to study after class. The existing recording devices are mainly tripods and cameras. Due to the limited space and large flow of people in the classroom, the tripod is easily bumped, causing it to tip over and the camera to fall to the ground and damage it. Therefore, we propose an automatic recording device for smart teaching terminals and its usage method. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic recording device for a smart teaching terminal and its usage method, so as to solve the problems mentioned in the background art.

[0005] Further optimization measures for this technical solution are as follows:

[0006] As an improvement, the protective component includes a protective member mounted on a tripod to protect the recording equipment body on the tripod. The protective member is provided with a deflector to expand the protection range of the recording equipment body. The protective member is also provided with a locking member to fix the protective member in place.

[0007] As an improvement, the protective component includes multiple mounting bases mounted on a tripod, each mounting base having a rotating shaft, a connecting plate mounted on the rotating shaft, the connecting plate being rotatably connected to the rotating shaft, the connecting plate being connected to the protective plate, and a torsion spring on the rotating shaft for use with the protective plate.

[0008] As an improvement, the deflecting component includes a deflection groove disposed on the protective plate, a deflection shaft disposed in the deflection groove, a deflection plate rotatably disposed on the deflection shaft, a fixing plate disposed on both the protective plate and the deflection plate, a deflection spring disposed between the plurality of fixing plates, and a limit block disposed on the protective plate.

[0009] As an improvement, the locking component includes multiple mating slots on the tripod, a locking rod that mates with the mating slots on the protective plate, a locking groove on the locking rod, a positioning plate on the tripod, a positioning rod that slidably mates with the locking groove on the positioning plate, the positioning rod passing through the mating slot and slidably connected to the mating slot, the end of the positioning rod that contacts the locking groove being hemispherical, a limit plate on the positioning rod, a positioning spring on the positioning rod, and the positioning rod passing through the positioning spring.

[0010] As an improvement, the triggering component includes a trigger element mounted on the tripod, which releases control over the protective plate when the tripod tilts. The trigger element is equipped with a control element, which secures the protective plate in its normal state.

[0011] As an improvement, the trigger includes a support rod mounted on a tripod, a mounting groove is provided in the support rod, a trigger spring is provided in the mounting groove, a push rod is slidably mounted in the mounting groove, the push rod is connected to the trigger spring, multiple racks are provided on the push rod, a rotating groove is provided on the support rod, a mounting rod is provided on the tripod, and a trigger gear that cooperates with the racks is rotatably mounted on the mounting rod.

[0012] As an improvement, the control component includes a drive shaft mounted on a trigger gear, a connecting rod mounted on a tripod, a rotating shaft rotatably mounted on the connecting rod, a first drive pulley mounted on the drive shaft, a second drive pulley mounted on the rotating shaft, a drive belt mounted on the first and second drive pulleys, a lead screw mounted at the end of the rotating shaft away from the second drive pulley, and a connecting seat mounted on the deflection plate, the connecting seat being threadedly connected to the lead screw.

[0013] As an improvement, a protective shell is provided on the support rod at the position of the trigger gear.

[0014] As an improvement, the automatic recording device for the smart teaching terminal is used as follows:

[0015] S1: In response to the command to start recording classroom video, acquire teacher video and student video;

[0016] S2: Perform behavior recognition on the teacher's behavior in the teacher's video to obtain teacher behavior recognition information;

[0017] S3: Perform behavior recognition on the student behavior in the student video to obtain student behavior recognition information;

[0018] S4: Generate at least one class signal based on the teacher behavior recognition information or the student behavior recognition information;

[0019] S5: Based on the at least one class start signal, determine whether the teacher has started the class using a pre-trained class start recognition model;

[0020] S6: Upon confirming the start of the lesson, generate a recording instruction for the classroom video and send it to the recording terminal;

[0021] S7: The recording terminal records the classroom video according to the recording instruction.

[0022] The present invention has at least the following beneficial effects: This intelligent teaching terminal uses an automatic recording device and its method of use. Unlike the prior art, when the recording device is bumped and tilted, a spring is triggered to push the gear to move. The rotating shaft removes the fixing of the lead screw and the connecting seat, further releasing the protective plate. Then, the protective plate flips under the drive of the torsion spring, protecting the recording device body. This ensures that when the recording device body falls to the ground, the protective plate contacts the ground first, buffering the impact force and preventing the recording device body from directly colliding with the ground and causing damage to the equipment, greatly improving the safety of the recording device body.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0035] Please see Figure 1-10 The present invention provides a technical solution:

[0036] An automatic recording device for a smart teaching terminal and its usage method include a tripod 1 and a recording device body 2 mounted on the tripod 1, as well as multiple protective plates 3 mounted on the tripod 1; a protective component 4 mounted on the tripod 1, which drives the protective plates 3 to protect the recording device body 2; and a trigger component 8 mounted on the tripod 1, which activates the protective component 4 to protect the recording device body 2 when the tripod 1 tilts.

[0037] The protective component 4 includes a protective element 5 mounted on the tripod 1, which protects the recording equipment body 2 on the tripod 1. The protective element 5 is provided with a deflector 6, which expands the protection range of the recording equipment body 2. The protective element 5 is provided with a locking element 7, which fixes the protective element 5.

[0038] The protective component 5 includes multiple mounting bases 51 mounted on the tripod 1. Each mounting base 51 has a rotating shaft 52, and the rotating shaft 52 has a connecting plate 53. The connecting plate 53 is rotatably connected to the rotating shaft 52 and is connected to the protective plate 3. The rotating shaft 52 has a torsion spring 54 that works with the protective plate 3. Under the elastic force of the torsion spring 54, the protective plate 3 flips and surrounds the recording equipment body 2. The protective component 5 ensures that the recording equipment body 2 will not collide with the ground when the tripod 1 is tilted, thus preventing damage to the recording equipment body 2.

[0039] The deflecting component 6 includes a deflection groove 61 disposed on the protective plate 3, a deflection shaft 62 disposed in the deflection groove 61, a deflection plate 63 rotatably disposed on the deflection shaft 62, a fixing plate 64 disposed on both the protective plate 3 and the deflection plate 63, a deflection spring 65 disposed between multiple fixing plates 64, and a limit block 66 disposed on the protective plate 3. The deflecting component 6 expands the protective area of ​​the protective plate 3, while the limit block 66 prevents the deflection plate 63 from excessive deflection.

[0040] The locking component 7 includes multiple mating slots 71 on the tripod 1. The protective plate 3 has locking rods 72 that mate with the mating slots 71. The locking rods 72 have locking grooves 73. The tripod 1 has a positioning plate 74. A positioning rod 75 that mates with the locking grooves 73 is slidably mounted on the positioning plate 74. The positioning rod 75 passes through and is slidably connected to the mating slots 71. The end of the positioning rod 75 that contacts the locking groove 73 is hemispherical. A limit plate 76 is provided on the positioning rod 75. A positioning spring 77 is provided on the positioning rod 75, and the positioning rod 75 passes through the positioning spring 77. Under the elastic force of the torsion spring 54, the locking rod 72 aligns with the docking groove 71. Since the diameter of the docking groove 71 is larger than that of the locking rod 72, the locking rod 72 can smoothly enter the docking groove 71. Simultaneously, under the compression of the locking rod 72, the positioning rod 75 retracts, which in turn compresses the positioning spring 77 until the positioning rod 75 is aligned with the locking groove 73. Then, under the elastic force of the positioning spring 77, the positioning rod 75 enters the locking groove 73, thereby completing the fixation of the protective plate 3. The locking element 7 prevents the protective plate 3 from springing up under the elastic force of the torsion spring 54 after the tripod 1 tilts, thus enhancing the protective performance of the protective plate 3.

[0041] The triggering component 8 includes a trigger 9 mounted on the tripod 1. The trigger 9 releases the control of the protective plate 3 when the tripod 1 tilts. The trigger 9 is equipped with a control component 10, which fixes the protective plate 3 in the normal state.

[0042] The trigger element 9 includes a support rod 91 mounted on the tripod 1. A mounting groove 92 is provided within the support rod 91, and a trigger spring 93 is installed within the mounting groove 92. A push rod 94 is slidably mounted within the mounting groove 92 and connected to the trigger spring 93. Multiple racks 95 are mounted on the push rod 94. A rotating groove 96 is provided on the support rod 91. A mounting rod 97 is mounted on the tripod 1, and a trigger gear 98 that rotatably engages with the racks 95 is mounted on the mounting rod 97. When the tripod 1 tilts, the push rod 94 slides under the push of the trigger spring 93, causing the racks 95 to move synchronously and simultaneously rotating the trigger gear 98 that engages with the racks 95. The elastic force of the trigger spring 93 is less than the weight of the recording equipment body 2, therefore it does not affect the stability of the tripod 1.

[0043] The control component 10 includes a drive shaft 101 mounted on a trigger gear 98, a connecting rod 102 mounted on a tripod 1, a rotating shaft 103 rotatably mounted on the connecting rod 102, a first drive pulley 104 mounted on the drive shaft 101, a second drive pulley 105 mounted on the rotating shaft 103, a drive belt 106 mounted on both drive pulleys 104 and 105, a lead screw 107 mounted at the end of the rotating shaft 103 away from the second drive pulley 105, and a connecting seat 108 mounted on the deflection plate 63. The seat 108 is threadedly connected to the lead screw 107, triggering the gear 98 to rotate, which in turn drives the drive shaft 101 to rotate. Simultaneously, the drive pulley 104 mounted on the drive shaft 101 rotates. The rotation of the drive pulley 104 drives the drive pulley 105 to rotate via the drive belt 106. The rotation of the drive pulley 105 drives the rotating shaft 103 connected to it to rotate. The rotation of the rotating shaft 103 drives the lead screw 107 to rotate, thereby causing the connecting seat 108 to disengage from the lead screw 107.

[0044] The usage method of the automatic recording device for smart teaching terminals is as follows:

[0045] S1: In response to the command to start recording classroom video, acquire teacher video and student video;

[0046] S2: Perform behavior recognition on the teacher's behavior in the teacher's video to obtain teacher behavior recognition information;

[0047] S3: Perform behavior recognition on the student behavior in the student video to obtain student behavior recognition information;

[0048] S4: Generate at least one class signal based on the teacher behavior recognition information or the student behavior recognition information;

[0049] S5: Based on the at least one class start signal, determine whether the teacher has started the class using a pre-trained class start recognition model;

[0050] S6: Upon confirming the start of the lesson, generate a recording instruction for the classroom video and send it to the recording terminal;

[0051] S7: The recording terminal records the classroom video according to the recording instruction.

[0052] In use, when tripod 1 tilts, push rod 94 slides under the push of trigger spring 93, causing rack 95 to move synchronously, which in turn drives trigger gear 98, which works in conjunction with rack 95, to rotate. The elastic force of trigger spring 93 is less than the weight of the recording device body 2, so it does not affect the stability of tripod 1. The rotation of trigger gear 98 further drives drive shaft 101 to rotate, which in turn drives drive pulley 104 mounted on drive shaft 101 to rotate. The rotation of drive pulley 104 drives drive pulley 105 to rotate via drive belt 106. The rotation of drive pulley 105 simultaneously drives the rotating shaft 103 connected to drive pulley 105 to rotate. The rotation of rotating shaft 103 drives lead screw 107 to rotate, thereby causing connecting seat 108 to disengage from lead screw 107. When the connecting seat 108 disengages from the lead screw 107, the protective plate 3 flips under the elastic force of the torsion spring 54, enclosing the recording equipment body 2. The protective component 5 prevents the recording equipment body 2 from colliding with the ground when the tripod 1 tilts, thus avoiding damage to the recording equipment body 2. At the same time, under the elastic force of the torsion spring 54, the locking rod 72 engages with the docking groove 71. Since the diameter of the docking groove 71 is larger than that of the locking rod 72, the locking rod 72 can smoothly enter the docking groove 71. Simultaneously, under the pressure of the locking rod 72, the positioning rod 75 retracts, which in turn compresses the positioning spring 77 until the positioning rod 75 is aligned with the locking groove 73. Then, under the elastic force of the positioning spring 77, the positioning rod 75 enters the locking groove 73, thereby completing the fixation of the protective plate 3 and further protecting the recording equipment body 2. Example 2

[0053] Please see Figure 1-10 The present invention provides a technical solution:

[0054] Unlike Embodiment 1, the support rod 91 is provided with a protective shell 11 at the position of the trigger gear 98. The protective shell 11 can protect the trigger gear 98 and the rack 95, and extend the service life of the equipment.

[0055] In use, when tripod 1 tilts, push rod 94 slides under the push of trigger spring 93, causing rack 95 to move synchronously, which in turn drives trigger gear 98, which works in conjunction with rack 95, to rotate. The elastic force of trigger spring 93 is less than the weight of the recording device body 2, so it does not affect the stability of tripod 1. The rotation of trigger gear 98 further drives drive shaft 101 to rotate, which in turn drives drive pulley 104 mounted on drive shaft 101 to rotate. The rotation of drive pulley 104 drives drive pulley 105 to rotate via drive belt 106. The rotation of drive pulley 105 simultaneously drives the rotating shaft 103 connected to drive pulley 105 to rotate. The rotation of rotating shaft 103 drives lead screw 107 to rotate, thereby causing connecting seat 108 to disengage from lead screw 107. When connecting seat 108 disengages from lead screw 107, Under the elastic force of the torsion spring 54, the protective plate 3 flips over, surrounding the recording equipment body 2. The protective component 5 prevents the recording equipment body 2 from colliding with the ground when the tripod 1 is tilted, thus avoiding damage to the recording equipment body 2. At the same time, under the elastic force of the torsion spring 54, the locking rod 72 aligns with the docking groove 71. Since the diameter of the docking groove 71 is larger than that of the locking rod 72, the locking rod 72 can smoothly enter the docking groove 71. Simultaneously, under the compression of the locking rod 72, the positioning rod 75 retracts, driving the positioning spring 77 to compress until the positioning rod 75 is aligned with the locking groove 73. Then, under the elastic force of the positioning spring 77, the positioning rod 75 enters the locking groove 73, thereby completing the fixation of the protective plate 3 and further protecting the recording equipment body 2. At the same time, the protective shell 11 can protect the trigger gear 98 and the rack 95, extending the service life of the equipment.
