Description

Technical Field

[0001] This invention relates to the field of multimedia data technology, and in particular to a multimedia data acquisition device and system. Background Technology

[0002] As the demand for multimedia data continues to grow in fields such as entertainment, security, and scientific research, the requirements for the real-time performance, integrity, and compatibility of data acquisition are constantly increasing. Therefore, multimedia data acquisition equipment and systems are established to simultaneously acquire, adapt, and preprocess diverse data such as images, audio, and video, providing a stable and reliable basic data source for subsequent data storage, analysis, and application.

[0003] The existing equipment has the following shortcomings: Because most existing multimedia data acquisition equipment is stored and managed in a decentralized manner and connected to a separate power supply for charging, the equipment is stored in a messy and disorderly manner, occupies a lot of space, and is prone to loss, damage, and other issues. At the same time, decentralized charging requires multiple charging interfaces and cables, which is cumbersome to operate and poses power safety hazards. It may also lead to insufficient battery life due to individual devices not charging in time, affecting the continuity of data acquisition tasks. In addition, decentralized storage requires each device to be searched and checked one by one when calling up and inventorying the equipment, which is inefficient and makes it difficult to achieve unified operation and maintenance management of the acquisition equipment, increasing manpower management costs and thus affecting the smooth progress and operational efficiency of the overall data acquisition work.

[0022] This application also discloses a multimedia data acquisition system, including:

[0023] The main control module is electrically connected to the device motherboard, control keyboard and display screen. It is used to receive operation commands from the control keyboard, parse the commands and send control signals to each execution unit.

[0043] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0044] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0045] Example 1:

[0046] A multimedia data acquisition device and system, such as Figures 1 to 7 As shown, including housing 1, it also includes:

[0047] The intelligent storage structure 3 is located inside the top of the housing 1. The intelligent storage structure 3 includes a storage box 301 installed on one side inside the housing 1. The storage box 301 has a storage slot 302 inside. The storage slot 302 is movably connected to a box body 305. A bottom plate 303 is fixed inside the bottom of the box body 305. A wireless charging module is provided at the bottom inside the storage box 301.

[0048] The acquisition unit 12 for multimedia data acquisition is installed on the top of the housing 305;

[0049] A flip cover 13 for sealing the storage box 301 is movably connected to one side of the top of the housing 1, and a combination lock 2 is installed on the side of the flip cover 13.

[0050] Fixed partition 19 is fixed inside both sides of the housing 1. An air intake filter 4 is fixed inside the fixed partition 19. An air intake fan 18 is installed on one side of the fixed partition 19. An exhaust partition 15 is installed on the side of the housing 1.

[0051] The cleaning structure 5 for automatically cleaning the intake filter 4 is set on one side of the fixed partition 19;

[0052] A locking structure 9 for locking the housing 305 is provided at the bottom of the storage box 301;

[0053] The support structure 8, which supports the housing 1, is located inside the bottom of the housing 1.

[0054] A display screen 11 is connected to the other side of the top of the housing 1 with damping rotation, and a control keyboard 7 is provided below the display screen 11. A data interface 10 is provided on one side of the control keyboard 7. Lithium batteries for energy storage are installed inside the housing 1. A motherboard for data processing is provided below the data interface 10. A first wireless transceiver module 14 is installed on the side of the housing 1 and electrically connected to the motherboard through wires.

[0055] The acquisition unit 12 can be equipped with multimedia data acquisition devices such as cameras and microphones. The housing 305 has a control unit 17 inside. The control unit 17 includes a control board 1701 installed inside the housing 305. One side of the control board 1701 is electrically connected to a second wireless transceiver module 1703 via wires. The housing 305 has a sub-battery 1702 installed inside. A handle 6 is fixed on one side of the housing 1, and a caster 16 is installed on the other side of the housing 1.

[0056] In this embodiment, when the multimedia data acquisition device and system are needed, the operator unlocks the password lock 2 by entering a password and simultaneously rotates the flip cover 13 to open it. Then, the housing 305 is removed, and acquisition units 12, such as cameras or microphones, are assembled according to actual acquisition needs. After assembly, the operator sets various data acquisition parameters via the control keyboard 7, and the parameter setting interface is simultaneously displayed on the screen 11, facilitating real-time verification of parameter information. During this process, the lithium battery continuously powers the mainboard, the first wireless transceiver module 14, and other core components inside the housing 1. The sub-battery 1702... This provides stable power support for the control unit 17 and the acquisition unit 12. The motherboard establishes a communication connection with the second wireless transceiver module 1703 through the first wireless transceiver module 14, and realizes data interaction with the control unit 17 through the second wireless transceiver module 1703, thereby ensuring the accurate issuance of acquisition commands and the real-time transmission of acquisition data. At the same time, the intake fan 18 starts to operate, driving the outside air into the housing 1 after being filtered by the intake filter 4. The heat generated by the operation of the equipment is discharged to the outside through the exhaust baffle 15, which to a certain extent maintains a suitable working temperature inside the equipment and ensures the stable operation of each component.

[0057] To address the inconvenience of managing and storing data collection units; such as... Figures 1-4 As shown, the wireless charging module includes a wireless charging transmitter 304 fixed inside the bottom of the storage slot 302, a wireless charging receiver 307 adapted to the wireless charging transmitter 304 installed on the top of the base plate 303, heat dissipation holes 306 are provided at the bottom of both sides of the storage slot 302, and the housing 305 and the storage slot 302 are connected by a plug-in connection. When the housing 305 is located inside the storage slot 302, the wireless charging transmitter 304 and the wireless charging receiver 307 are located on the same vertical center line.

[0058] In this embodiment, the housing 305 is aligned with the storage slot 302 and smoothly pushed in. The inner wall of the storage slot 302 guides the housing 305, ensuring precise embedding. This automatically aligns the wireless charging transmitter 304 with the wireless charging receiver 307. The mainboard then activates the wireless charging module, using electromagnetic induction to transfer electrical energy from the lithium battery to the sub-battery 1702, achieving efficient charging. Simultaneously, the heat dissipation vents 306 continuously ventilate and dissipate heat, preventing heat buildup from prolonged operation. When the housing 305 needs to be retrieved, the locking structure 9 is unlocked, and the housing 305 is then pulled out of the storage slot 302, allowing for quick resumption of data collection. This significantly improves the device's storage convenience and battery life.

[0059] To address the issue of the box easily shaking and falling off after storage; such as Figures 3-4As shown, the locking structure 9 includes a connecting frame 904 movably connected to both sides of the bottom end of the storage box 301. Moving wheels 907 are rotatably connected to both sides of the connecting frame 904. A guide shell 903, fixedly connected to the storage box 301, is fitted on the outer side of the moving wheels 907. A second magnetic buckle 906 is fixed inside the top of the guide shell 903. An electric push rod 905, with its telescopic end connected to the connecting frame 904, is installed at the bottom inside the housing 1. A reinforcing seat 902 is fixed at the top of the base plate 303. A first magnetic buckle 901 is installed inside the reinforcing seat 902. The second magnetic buckle 906 forms a sliding structure with the guide shell 903 via the moving wheels 907. When the electric push rod 905 retracts, the second magnetic buckle 906 and the first magnetic buckle 901 are located on the same vertical center line.

[0060] In this embodiment, when the box 305 needs to be fixed after being pushed into the storage slot 302, the main board sends a command to activate the electric push rod 905. The electric push rod 905 retracts and pulls the connecting frame 904 to move. At the same time, the connecting frame 904 drives the moving wheel 907 to slide along the inside of the guide shell 903, thereby driving the second magnetic buckle 906 to move synchronously. Then, the second magnetic buckle 906 is precisely aligned with the first magnetic buckle 901 and generates a magnetic attraction force, fixing the box 305 in the storage slot 302, preventing the box 305 from shaking or falling off during the movement of the device. When it is necessary to unlock, the main board sends a command to control the electric push rod 905 to extend, pushing the connecting frame 904 to move in the opposite direction, so that the second magnetic buckle 906 separates from the first magnetic buckle 901, and the locking state is released. This ensures the stability of the box 305 when it is stored and the convenience of access to a certain extent.

[0061] Example 2:

[0062] A multimedia data acquisition device and system, such as Figures 5-6 As shown, in order to solve the problem of dust accumulation and cumbersome cleaning of the air intake filter, this embodiment makes the following improvements based on embodiment 1: The cleaning structure 5 includes a lead screw 502 rotatably connected to the top of one side of the fixed partition 19, a stepper motor 503 with the output shaft end connected to the rotating end of the lead screw 502 fixed to the side of the fixed partition 19, a guide rod 504 fixed to the bottom of one side of the fixed partition 19, a movable frame 501 threadedly connected to the lead screw 502 slidably connected to the outside of the guide rod 504, a first magnetic block 505 fixed to one side of the movable frame 501, a cleaning frame 507 slidably connected to one side of the fixed partition 19, a cleaning brush 508 fixed to the side of the cleaning frame 507 near the air intake filter 4, and second magnetic blocks 506 magnetically connected to the first magnetic block 505 fixed at both ends of the cleaning frame 507 near the first magnetic block 505.

[0063] In this embodiment, when dust accumulates on the surface of the air intake filter 4, affecting the air intake efficiency, the stepper motor 503 is started by the timer program set on the main board. The stepper motor 503 drives the lead screw 502 to rotate. At the same time, the moving frame 501 moves smoothly along the guide rod 504 under the threaded transmission of the lead screw 502. The moving frame 501 drives the first magnetic block 505 to move synchronously. Through the magnetic attraction between the first magnetic block 505 and the second magnetic block 506, the cleaning frame 507 is pulled to slide along one side of the fixed partition 19. The cleaning frame 507 drives the cleaning brush 508 to move synchronously. The cleaning brush 508 makes full contact with the surface of the air intake filter 4 and cleans the dust, thereby removing the dust accumulated on the filter surface. Then, the stepper motor 503 drives the lead screw 502 to rotate in the opposite direction, so that the moving frame 501 and the cleaning frame 507 are reset, completing one cleaning operation, which to a certain extent ensures the unobstructed flow of the air intake filter 4.

[0064] To address the issue of poor stability when placed on uneven ground; such as Figure 2 and Figure 7 As shown, the support structure 8 includes a flip frame 801 that is damped and rotatably connected to the bottom of the housing 1. The flip frame 801 has latching grooves 807 on both sides. A support leg 809 is slidably connected to one side of the flip frame 801. A pull plate 808 is slidably connected to the inside of the support leg 809. Guide plates 806 are fixed on both sides of the inside of the support leg 809. A connecting rod 802 connected to the pull plate 808 is slidably connected to the inside of the guide plate 806. A return spring 805 connected to the guide plate 806 is fixed to the outside of the connecting rod 802. A push arm 804 is rotatably connected to the side of the connecting rod 802 away from the pull plate 808. A locking buckle 803 slidably connected to the support leg 809 is rotatably connected to one end of the push arm 804.

[0065] In this embodiment, when the equipment needs to be placed on uneven ground for data collection, the rotating frame 801 is rotated to rotate out from the bottom of the housing 1. Then, the pull plate 808 is pulled, which drives the connecting rod 802 to slide along the guide plate 806. At the same time, the return spring 805 is stretched. At this time, the connecting rod 802 drives the push arm 804 to rotate, so that the push arm 804 pulls the locking buckle 803 to separate from the buckle groove 807. After the locking state is released, the extension length of the support leg 809 can be adjusted according to the flatness of the ground. After adjusting to a suitable height, the pull plate 808 is released. The rebound force of the return spring 805 drives the connecting rod 802 to return to its original position, and the push arm 804 pulls the locking buckle 803 to re-embed into the buckle groove 807, so that the length of the support leg 809 is fixed. This allows the equipment to be used stably in complex ground environments, which improves the environmental adaptability and operational stability of the equipment to a certain extent.

[0066] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
