[0002] With the rapid development of autonomous driving technology, its applications in multiple fields such as transportation, logistics, and agriculture are becoming increasingly widespread. An autonomous driving system usually needs to process a large amount of sensor data and generate control instructions in real time, which poses extremely high requirements for the hardware design of the system. However, most of the existing autonomous driving systems adopt an integrated design, and the coupling degree between functional modules is relatively high. As a result, when upgrading the hardware or expanding the functions, the entire system needs to be extensively modified, which not only incurs high development costs but also may affect the overall stability due to changes in a single module. In addition, the existing systems have limited adaptability to external devices and are difficult to meet the diverse needs of different unmanned platforms. At the same time, sensor upgrades or expansions often require adjustments to the system architecture, further restricting the flexibility and adaptability of the system. These problems make the upgrade and maintenance of current autonomous driving systems complex and inefficient, and it is difficult to meet the actual application scenario requirements of high performance and high reliability. Therefore, there is an urgent need for a modular-designed autonomous driving system to improve the flexibility, scalability, and upgrade convenience of the system, while ensuring its stability and compatibility.

[0025] The data output end of the acquisition board is electrically connected to the data input end of the core board through a standard plug, and the instruction output end of the core board is electrically connected to the instruction receiving end of the interface board, forming a first instruction control route of "acquisition board - core board - interface board"; the status output end of the interface board is electrically connected to the status data input end of the core board, and the instruction output end of the core board is electrically connected to the instruction receiving end of the acquisition board, forming a second instruction control route of "interface board - core board - acquisition board".

[0026] The interface board has multiple expansion interfaces, which can be flexibly configured according to the needs of peripheral devices to adapt to different unmanned platforms. The core board is designed independently of the interface board and the acquisition board, and supports hardware upgrade or function expansion without modifying the interface board and the acquisition board. The acquisition board supports the access of multiple types of sensors and can upgrade and expand the sensors according to requirements.

[0027] The communication protocol between the interface board and the core board supports multiple data transmission modes, specifically including serial communication, parallel communication, and network communication. The acquisition board includes a signal conditioning circuit for preprocessing the raw data collected by the sensors.

[0028] The working principle of the present invention is as follows: The system consists of an interface board, a core board, an acquisition board, and a power management module. Each module is physically connected and communicates through standard connectors, ensuring good interchangeability and compatibility between modules. The following is a detailed description of the specific functions and implementation methods of each module:

[0029] Interface board: As the access unit for external devices, the interface board is designed with multiple expansion interfaces and can be flexibly configured according to actual needs to adapt to different types of unmanned platforms (such as autonomous vehicles, drones, etc.). The interface board is connected to the core board through a standard connector and supports multiple data transmission modes, including serial communication, parallel communication, and network communication, to meet the communication requirements of different peripherals.

[0030] Core board: The core board is the processing center of the system, equipped with a high-performance processor, responsible for data processing, algorithm operation, and generation of control instructions. The core board is designed independently of the interface board and the acquisition board. When hardware upgrades or function expansions are required, only the core board needs to be replaced, without modifying the designs of other modules. This modular design greatly simplifies the system upgrade process and reduces development costs.

[0031] Acquisition board: The acquisition board is used to collect sensor data and is connected to the core board through a standard connector. The acquisition board supports the access of multiple types of sensors, such as cameras, lidar, ultrasonic sensors, etc., and can upgrade or expand the sensors according to requirements. In addition, the acquisition board is built-in with a signal conditioning circuit, which can preprocess the raw data collected by the sensors to improve data accuracy and system adaptability.

[0032] Power management module: The power management module provides stable power supply for the interface board, the core board, and the acquisition board, and supports multi-voltage level output to meet the power supply requirements of different modules. This design ensures the reliable operation of the system in complex working environments.

[0033] Instruction control routes: Two main instruction control routes are designed in the system:

[0034] The first route is "acquisition board - core board - interface board". Among them, the acquisition board transmits sensor data to the core board, and the core board generates control instructions after processing and sends them to external devices through the interface board.

[0035] The second route is "interface board - core board - acquisition board". Among them, the interface board feeds back the status information of external devices to the core board, and the core board adjusts the working mode or parameters of the sensor according to the status information and issues instructions through the acquisition board.

[0036] Through the above modular design and clear function division, the present invention realizes the efficient upgrade, flexible expansion and high stability of the autonomous driving system, and is applicable to unmanned platforms in a variety of application scenarios.

[0037] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural modes to cover the embodiments without creative efforts without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
