Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] This application describes a control board comprising a core board and a baseboard. This control board can be applied to various applications requiring control, such as digital signage, high-end instruments, medical devices, industrial applications, and automotive infotainment systems. When using this control board, corresponding control programs and software can be embedded within it, and external hardware devices can be connected via interfaces on the control board, thereby enabling the control board to control or process the corresponding hardware devices.

[0029] like Figure 1 and Figure 2 As shown, an embodiment of this application discloses a control board with a separable core board, comprising a base plate and a core board that can cooperate with each other. Specifically, a female connector end is provided in the middle of the base plate. The female connector end shown is a board-to-board connector end, which allows a corresponding male end to be inserted and communicatively connect the two circuit boards. In this application, by providing a female end on the base plate and a matching male end on the core board, a detachable board-to-board connection between the core board and the base plate is achieved.

[0030] like Figure 2 As shown, the base plate also includes a power switch 1 for controlling the connection or disconnection of the power supply to the entire control board. A power input port 2 is used to connect the control board to an external power source. ETH0 gigabit network ports 3 and 4 are used for connecting the control board to a high-speed network. The base plate also includes a USB interface for data transfer, and camera interfaces 10 and 11 for connecting to a camera. Additionally, a wireless network antenna interface 18 is provided on the base plate. When the control board needs to use a wireless network for signal transmission, connecting an external wireless antenna allows for wireless network signal transmission across the entire control board. Furthermore, the base plate also includes an LVDS interface 25 and a DSI interface 27 for connecting corresponding external devices.

[0031] In this embodiment, an RK3568 AIoT high-performance processing chip is mounted on the core board, located on the front side of the core board. The RK3568 processor features a maximum clock speed of 2GHz, quad cores, and a 64-bit architecture. The processor utilizes the A55 architecture and integrates a G52 GPU, a 1-Tops NPU, and other powerful embedded hardware engines, providing excellent performance for high-end applications. The processor's built-in 3D GPU supports almost all formats of H.264 4k@60fps decoding, H.265 4k@60fps decoding, H.264 / H.265 1080p@60fps encoding, and high-quality JPEG encoding / decoding. It is also fully compatible with OpenGL ES 1.1 / 2.0 / 3.2, OpenCL 2.0, and Vulkan 1.0. A dedicated 2D hardware engine maximizes display performance and provides a smooth user experience. The processor's embedded NPU coprocessor unit supports mixed INT8 / INT16 operations. Furthermore, thanks to the NPU's strong compatibility, it can easily convert network models based on a range of frameworks such as TensorFlow / MXNet / PyTorch / Caffe. Figure 1 As shown, in this embodiment, the back of the core board is provided with a male core board connector that matches the female connector of the baseboard. The core board can communicate with the baseboard by inserting the male core board connector into the female connector of the baseboard. This allows the entire control board to achieve its control requirements centered on the core board, especially the RK3568 AIoT high-performance processing chip on the core board, through the chip's high-performance processing capabilities.

[0032] In this embodiment, the core board is a separable control board. The development baseboard and core board are separately configured, allowing for independent development and setup of the core board and baseboard, thus improving development efficiency. Furthermore, the baseboard and core board are pluggable, meaning that if any component of the baseboard fails, the core board can be detached and applied to other baseboards, enhancing its usability. This also reduces the overall cost of the control board. Moreover, in this application, the core board uses the RK3568 AIoT high-performance processing chip, whose superior performance enables the control board to meet the human-machine interaction, rich graphics, and high-response requirements of digital signage, high-end instruments, medical devices, industrial and automotive in-vehicle entertainment systems. The core board and baseboard are detachably connected via board-to-board connectors, facilitating easy connection and disconnection.

[0033] Furthermore, such as Figure 2 As shown, as a feasible connection method, three female connectors can be installed on the base plate. Figure 1The core board shown has three male connector terminals (A, B, and C) on its back. When connecting the core board and the baseboard, the three mating female baseboard connector terminals and the male core board connector terminals interlock, establishing a communication connection between the core board and the baseboard. This allows the core board to process and analyze signals, acquire signals from external devices via the baseboard, and send control signals to external devices connected to the baseboard through its interfaces. Each pair of male and female connector terminals works in conjunction with the three mating baseboard connector terminals; however, the specific models of the three sets of male and female terminals can be customized as needed. They can be identical or different models.

[0034] As one possible implementation, both the core board and the baseboard can be designed with a common rectangular board structure. For the three male connector terminals on the core board, one can be positioned near the shorter side of the core board, and the other two can be positioned near the longer side of the core board. The three sets of male and female terminals form a triangular structure, which, while enabling communication between the core board and the baseboard via plug-in connection, also stably secures the core board to the baseboard, enhancing the stability of the core board connection.

[0035] Furthermore, to provide a rectangular core board mounting area 34 on the base plate that corresponds to the core board, which also serves as an interface socket for the core board, components matching the core board can be installed in the corresponding positions. To enhance the safety of the female connector, in this embodiment, the female connector of the base plate connector, corresponding to the male connector of the core board connector located on the short side of the core board, is located on the side of the core board mounting area furthest from the edge of the base plate. That is, as... Figure 2 As shown, the rectangular core board mounting area is located in the middle of one side of the rectangular base plate along its length, that is... Figure 2 The rectangular core board mounting area is located in the middle of the left side of the base plate, and its length direction aligns with that of the base plate. The long side of the rectangular core board mounting area is parallel to the long side of the base plate. Three female connectors are positioned near the top, bottom, and right side of the mounting area. This arrangement places all three female connectors in the middle of the base plate, avoiding the need for female connectors at the edges and preventing damage to the base plate during core board insertion.

[0036] Furthermore, the baseboard also features a PCIe Gigabit network expansion port ETH2 (5), a USB Type-C COTG interface 6, an AUDIO interface (MIC and HP) port 12, a GPIO interface 13, a 4xADC interface 14, an expansion 4xRS232 serial port 15, a CPU 6xRS232 serial port 16, an ESPI interface 17, a SATA interface 19, a MINI-PCIe card slot 20, a USB Type-C debug serial port 23, an HDMI interface 24, an LVDS interface 25, an EDP interface 26, a DSI interface 27, CAN1 and CAN2 interfaces 28, a PWM interface 29, and a button interface 30. It also includes a SIM card slot 21, a TF card slot 22, an FSPI interface 32, an RTC battery interface 31, and a recording microphone 33. The overall control board functions as follows: Figure 3 As shown, corresponding interfaces are provided for hardware devices that may be involved in various fields. The RK3568 AIoT high-performance processing chip connects to each interface, enabling this control board to be applied to various fields. Users can use this standard, unified control board to perform corresponding control development in various fields.

[0037] The specific interface settings are shown in Figure 2.

[0038]

[0039] Specifically, the baseboard features two USB 3.0 ports (7 and 8) and one USB 2.0 port (9), as well as two wireless network antenna ports (4G and 2.4G). Furthermore, there are two ETH0 gigabit network ports and two camera ports.

[0040] It should be noted that when setting up the various interfaces, the FSPI interface and RTC battery interface can be placed in the center of the base plate, while other interfaces on the base plate should be placed at the edges. The power switch can be placed in one corner of the rectangular structure of the base plate, making it easier to create a corresponding opening for the power switch on the housing when encapsulating the control board into the device.

[0041] Furthermore, in the solution of this application, two RTL8211F-CG chips are integrated into the core board as gigabit network communication interface chips, and corresponding peripheral circuits are also integrated into the core board, which greatly improves the functionality and ease of use of the core board, as detailed below. Figure 4 and Figure 5 As shown in the diagram, this design directly connects the converted network transmission signal to the connector pins. If the user needs to use the network function, they only need to connect 8 physical transmission signals to the RJ45 connector on the expansion baseboard to easily achieve network signal communication.

[0042] Furthermore, this application integrates a PCF8563T / 5 chip as an I2C interface RTC chip into the core board, which significantly improves the stability of the core board's RTC function. Specifically, as follows... Figure 6 As shown. This design solves the technical challenges of core board controller clock expansion that are common in the industry. By addressing the issues at the hardware circuit and underlying system levels, it completely resolves the stability and ease of use of the core board clock function.

[0043] Therefore, the core board in this application brings out all or most of the CPU's functional pins, and in particular, integrates the dual-channel gigabit network and RTC on the board. Users only need to design simple peripheral circuits for different products, reducing the development difficulty for customers. Moreover, the separation of the core board and the baseboard facilitates easier customer development and functional expansion. Using the core board and control board of this application can solve the challenges of complex embedded systems, reduce development difficulty, and greatly improve the development efficiency of the control board.

[0044] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical applications, or technical improvements to the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
