Description

Technical Field

[0001] This invention belongs to the field of data storage technology and relates to a universal platform integrating video data storage and processing, which can be used for the compression and storage of image and video information of various types of aerial guided bombs. Background Technology

[0002] Currently, the data storage devices used in my country's guided bombs suffer from limitations such as limited functionality, complex data retrieval operations, small storage space, and low transmission rates, failing to meet the development requirements of productization, modularization, and universalization for guided bombs. Faced with increasing demands for image and video information storage and ever-higher signal transmission rates, current data storage devices are no longer sufficient to meet these needs. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this invention provides a universal platform that integrates video data storage and processing. This platform selects signal interfaces based on the actual application environment and storage modules based on data size and post-processing requirements, thus possessing universality and wide applicability.

[0004] The solution to the technical problem of this invention is: a universal platform integrating video data storage and processing, including a motherboard, an interface conversion board, and an external storage device;

[0005] Motherboard: Receives external video data; if the video data is uncompressed, it compresses the video data and writes the compressed data to an external storage device or onboard storage space; if the video data is compressed, it directly stores it to an external storage device or onboard storage space; performs situational awareness or data fusion processing on the received video data as needed.

[0006] Interface conversion board: Expands the motherboard's interfaces by connecting other interfaces besides those built into the motherboard. By converting these other interfaces into interfaces compatible with the motherboard, it expands the range of signals that the motherboard can handle.

[0007] External storage device: When the motherboard's storage space is insufficient, the received video data will be transferred to an external storage device.

[0008] Furthermore, the motherboard includes a power conversion module, a main control chip, a storage module, external interfaces, and expansion interfaces;

[0009] Power conversion module: Converts external input voltage into the power supply voltage required by various components on the board, and the power input terminal is designed with reverse protection and overvoltage protection;

[0010] Main control chip: Receives video data input from external interfaces or interface conversion boards, compresses the video data and writes it to the on-board storage module or transfers it to an external storage device; or performs situational awareness or data fusion processing on the received video data and writes the processed results to the on-board storage module or transfers them to an external storage device.

[0011] Storage module: Used to store the underlying operating system and underlying driver module of the general platform, as well as the video data processing software designed on the basis of the underlying driver module; store the input data received by the external interface and the expansion interface, as well as the output data processed by the main control chip;

[0012] The external interface is a general-purpose external interface built into the motherboard, used to receive externally input data or to transfer data processed by the main control chip to an extended storage device;

[0013] The expansion interface is a general-purpose interface reserved on the motherboard for interfacing with an interface conversion board. When the motherboard's built-in external interfaces cannot receive certain signals, the interface conversion board converts the interfaces corresponding to these signals into expansion interfaces, which then connect to the motherboard.

[0014] Furthermore, the underlying driver module includes a system clock configuration module, an interface initialization and control module, a kernel usage allocation and scheduling setting module, and a system boot setting and system burning module.

[0015] Furthermore, the external interfaces include an RS interface, a network port, and a USB interface.

[0016] Furthermore, when storage space needs to be expanded, an external USB flash drive can be connected via the USB interface, and input data can be received via the network port or RS interface. The data processed by the main control chip is then transferred to the USB flash drive, and data can be read directly from the USB flash drive. At this time, the USB interface is not used to receive data, but only for data transfer.

[0017] Furthermore, the aforementioned situational awareness of the received video data refers to adding image processing algorithms to the video data processing software, and using these algorithms to analyze and process the received video data to achieve target identification and tracking.

[0018] Furthermore, data fusion processing of the received video data refers to the comprehensive utilization of the received video data, navigation data received from external interfaces, and information from different sensors to improve the positioning accuracy of navigation.

[0019] Furthermore, the main control chip is the multi-core high-performance processing chip RK3588.

[0020] Furthermore, the general platform can also receive image data and perform compression, storage, situational awareness, or data fusion processing on the image data.

[0021] The beneficial effects of this invention compared to the prior art are:

[0022] (1) Existing data storage devices mostly have a single interface and limited speed, which cannot receive many high-definition images and high-speed video signals. The video data storage and processing integrated universal platform described in this invention increases the types of interfaces to match different signals, adopts high-speed interfaces to improve interface speed, and also adopts an interface conversion board solution to further expand interface adaptability, adapting to as many image and video signals as possible on the market.

[0023] (2) Existing data storage devices can only store data but cannot process data. The video data storage and processing integrated general platform described in this invention can realize the compression processing of image and video signals through corresponding software design, and can also realize more complex functions such as situational awareness or data fusion.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] This invention proposes a universal platform integrating video data storage and processing, such as... Figures 1-4 As shown, it includes a motherboard 1, an interface conversion board 2, and an external storage device 3;

[0032] Mainboard 1: Receives external video data. If the video data is uncompressed, it compresses the video data and writes the compressed data to the external storage device 3 or the onboard storage space. If the video data is compressed, it is directly stored in the external storage device 3 or the onboard storage space. It performs situational awareness or data fusion processing on the received video data as needed.

[0033] Interface conversion board 2: Expands the interfaces of motherboard 1 according to actual needs, connecting other interfaces besides the motherboard 1's built-in interfaces 104 to 107. By converting other interfaces into interfaces compatible with motherboard 1, the signal range that motherboard 1 can process is expanded.

[0034] External storage device 3: This is an external, ruggedized storage device added according to actual needs. When the storage space of the motherboard 1 is insufficient, the received video data will be transferred to the external storage device 3.

[0035] The motherboard 1 includes a power conversion module 101, a main control chip 102, a storage module 103, external interfaces 104-107, and an expansion interface 108;

[0036] Power conversion module 101: Converts external input voltage into the power supply voltage required by various components on the board. The power input terminal is designed with reverse protection and overvoltage protection.

[0037] Main control chip 102: Receives video data input from external interfaces 104-107 or interface conversion board 2, compresses the video data and writes it to on-board storage module 103 or transfers it to external storage device 3; or performs situational awareness or data fusion processing on the received video data, and writes the processed result to on-board storage module 103 or transfers it to external storage device 3.

[0038] Storage module 103: used to store the underlying operating system and underlying driver module of the general platform, as well as the video data processing software designed on the basis of the underlying driver module; and to store the input data received by the external interfaces 104-107 and the expansion interface 108, as well as the output data processed by the main control chip 102.

[0039] External interfaces 104 to 107 are general-purpose external interfaces built into the motherboard 1, used to receive externally input data, and can also transfer the data processed by the main control chip 102 to the extended storage device 3.

[0040] The expansion interface 108 is a general-purpose interface reserved for the motherboard 1, used to interface with the interface conversion board 2. When the external interfaces 104 to 107 of the motherboard 1 cannot receive certain signals, the interface conversion board 2 converts the interfaces corresponding to these signals into the expansion interface 108, and the signals enter the motherboard 1 through the expansion interface 108, thereby enabling the motherboard 1 to process these signals and expanding the applicability of the motherboard 1.

[0041] In storage module 103, the software design adopts a two-layer architecture: the first layer is a low-level driver module based on the operating system, including a system clock configuration module, various interface initialization and control modules, kernel usage allocation and scheduling settings module, system startup settings and system burning module, etc. The second layer is video data processing software designed on the basis of the low-level driver module. The main function of this software is to receive video data in real time. If the video data is uncompressed, it will be compressed and finally written to the external storage device 3 or the onboard storage space; if the video data is compressed, it will be directly stored in the target storage space. In addition, the software can also perform more complex functions such as situational awareness or data fusion on the received video data as needed, realizing various functions such as receiving, sending, storing and comprehensively processing video data.

[0042] The aforementioned situational awareness of the received video data refers to adding image processing algorithms to the video data processing software in the second-layer software architecture, and analyzing the received video data through image processing algorithms to achieve target identification and tracking.

[0043] The aforementioned data fusion processing of the received video data refers to making full use of all external interfaces to receive different data from different interfaces, including video data, navigation data, and other information from different sensors. Comprehensive analysis of these data can improve the positioning accuracy of navigation.

[0044] When it is necessary to perform situational awareness or data fusion on video data, the main control chip 102 performs calculations by calling the relevant programs in the storage module 103.

[0045] The expansion interface 108 is implemented using a common high-speed connector. Signals that cannot be directly connected to the motherboard are converted into signals that can be connected to the expansion interface through the expansion board, so that the motherboard can receive and process more signals through the expansion interface.

[0046] The general platform described in this invention can also receive image data and perform compression, storage, situational awareness, or data fusion processing on the image data.

[0047] Example 1

[0048] The universal platform for integrated video data storage and processing in this embodiment includes a motherboard, an interface conversion board, and an external storage device;

[0049] The motherboard functional block diagram is as follows Figure 2 As shown, it includes a power conversion module, a main control chip, a storage module, external interfaces, and expansion interfaces. The power conversion module on the motherboard converts the externally input 28V power into the power required by the various functional modules on the board, and also powers the reserved expansion interfaces. When an external interface conversion board is connected, it is powered through the expansion interfaces.

[0050] The main control chip is a multi-core high-performance processing chip, such as the RK3588, an 8-core processing chip with a built-in video codec and rich expansion interfaces, facilitating circuit design. The storage module uses 16GB of LPDDR4 memory and 128GB of eMMC storage. External interfaces include one RS422 interface, two Ethernet ports (Gigabit Ethernet + 100Mbps Ethernet), and one USB 3.0 interface. The RS422 interface can receive lower-speed, common signals, while the Ethernet and USB ports can receive high-speed signals. After receiving signals, the main control chip processes them and stores them in the onboard storage module. Data is retrieved through the onboard external interfaces.

[0051] When you need to expand storage space, you can connect an external USB flash drive via the USB 3.0 interface, such as... Figure 3 As shown, input data is received via the Ethernet port or 422 interface. After processing by the main control chip, the data is transferred to a USB flash drive. To retrieve data, simply read from the USB flash drive. In this case, the USB 3.0 interface cannot be used for receiving data; it is only used for data transfer.

[0052] When the input data interface is incompatible with the network port or USB interface, an external adapter board can be connected via the expansion interface for interface conversion. This converts other video signal formats into signals that meet the specified expansion interface protocol before they enter the motherboard, are processed by the main control chip, and stored in the target storage space. Figure 4 As shown.

[0053] Addressing the needs of platforms such as precision-guided weapons, this invention's platform enables efficient processing of video data, such as situational awareness and data fusion. The design utilizes a multi-core high-performance processing chip, allowing functional modules to be distributed across different cores, facilitating feature customization.

[0054] This application realizes the function of processing and storing multiple signals, especially high-speed video signals, on a single platform. It features simple operation, high transmission rate, and wide applicability, which greatly improves the applicability and reliability of the integrated video data storage and processing platform. It solves the problems of single function, complex operation, small storage space and low transmission rate of the storage devices used in current aerial bomb products.
