Description

Technical Field

[0001] This utility model relates to an airborne intelligent terminal, and more particularly to an airborne intelligent terminal based on a domestically produced chip. Background Technology

[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] Indoor flight missions of micro-drones typically lack GPS positioning capabilities, and positioning systems such as UWB and motion capture rely on external beacons, resulting in limited flexibility. Commonly used airborne positioning terminals in China often employ foreign edge computing equipment, lacking independent controllability and exhibiting poor integration. Camera calibration is required during installation for proper functioning. Some integrated navigation and positioning terminals from abroad are typically limited in functionality, have weak computing power, and cannot be independently developed, making it difficult to meet the diverse needs of drone flight missions.

[0004] To overcome these shortcomings, simply using existing computing devices on the market cannot meet the needs of drone flight missions, especially indoors where positioning is difficult. While installing integrated navigation and edge computing devices can meet the diverse needs of drone flight missions, these devices are bulky, have complex wiring, and are less reliable.

[0036] Figure 2 This is a schematic diagram of the power supply structure of this utility model. Detailed Implementation

[0037] This utility model adopts a domestically produced circuit board design, integrating the navigation and positioning unit, intelligent vision unit, corresponding sensor modules, and communication modules into a single terminal. It also provides a highly reliable I / O interface, enabling parallel processing of navigation and positioning tasks and intelligent vision tasks, thus providing stable positioning data and a high-efficiency computing platform for UAV indoor flight missions. The specific technical solution is as follows:

[0038] An airborne intelligent terminal based on domestically produced chips, the internal structure of which is as follows: Figure 1 As shown, it includes two computing units using the domestically produced RK3588 chip as the processor, namely the navigation and positioning unit and the intelligent vision unit; the navigation and positioning unit is electrically connected to the outside world through the J70A connector, and the navigation and positioning unit and the intelligent vision unit are interconnected through the FBB08009-F connector and the FBB08009-M connector.

[0039] Figure 1 The left side is the navigation and positioning unit, which has a built-in inertial navigation module to collect 200Hz angular velocity and acceleration data. It is electrically connected to the infrared global camera via the MIPI-CSI cable with an 8.01A0030200 connector to collect 25Hz infrared image data. It is powered by the J70A connector and uses two UART TTL serial ports and a USB 2.0 interface for external network communication.

It is powered by the navigation and positioning unit via an FBB08009-M connector and has no external communication.

[0041] The navigation and positioning unit and the intelligent vision unit communicate using the RGMII interface and the FBB08009-F and FBB08009-M connectors.

[0042] The inertial navigation module communicates with the navigation and positioning unit in real time via a TTL serial port.

[0043] The infrared global camera is connected to the navigation and positioning unit in real time via the MIPI CSI-2 interface, and the visible light roller shutter camera is connected to the intelligent vision unit in real time via the MIPI CSI-2 interface.

[0044] Example:

[0045] Figure 1 shows the structure of an airborne intelligent terminal designed in a specific embodiment of this utility model, including a navigation and positioning unit, an intelligent vision unit, and an external I / O interface.

[0046] The navigation and positioning unit uses an FBB08009-F connector to interconnect with the intelligent vision unit; it shares a 12V DC power input with the intelligent vision terminal via an FBB08009-M connector; and externally, it uses a J70A connector to bring out a TTL-UART serial port, a USB 2.0 interface, a network interface, and a power interface.

[0047] The intelligent vision unit uses an FBB08009-M connector to interconnect with the navigation and positioning unit; it shares the input power with the navigation and positioning unit through the FBB08009-M connector and does not provide a separate external output interface.

[0048] The navigation and positioning unit internally includes a CPU, NPU, multiple communication interfaces, RAM, ROM, debugging interface, and sensor modules, realizing functions such as data processing, data acquisition, data storage, and output transmission. The CPU and NPU use the domestically produced Rockchip RK3588 chip, possessing 6 TOPS floating-point operation capability and supporting deep learning frameworks such as TensorFlow and multimedia encoding / decoding capabilities. The RAM uses DDR4 specification with a capacity of 8GB. The ROM uses onboard eMMC memory with a capacity of 64GB, capable of supporting real-time operation of mainstream SLAM algorithms and map storage. It communicates with the inertial module JY-901B using the TTL-UART protocol and connects to the Veye SC130m infrared camera via a ribbon cable using the MIPI-CSI protocol and an 8.01A0030200 connector.

[0049] External network communication: The YT8521 physical layer network chip and XECJLT1606-A network transformer are used for external network communication via connectors.

[0050] The design of the intelligent vision unit's CPU, NPU, internal communication interface, RAM, ROM, and debugging interface is basically the same as that of the navigation and positioning unit. It does not have an inertial sensor module installed and uses the MIPI-CSI protocol to connect to the visible light camera Veye IMX462 via a ribbon cable through the X10B25U15T connector.

[0051] like Figure 2 The diagram shows a power supply structure designed in one embodiment of this utility model, including a power interface, a step-down rectifier chip, and a power management chip, supporting a 17~21V voltage input. The power supply is input to two JW5068 step-down chips via a J70A connector, which output 4V to the RK806 power management chip for overall power supply, and 5V respectively.

[0052] This utility model provides a concept and method for an airborne intelligent terminal based on domestically produced chips.
