[0002] With the continuous advancement of the "carbon peaking and carbon neutrality" strategy, ship electrification has become an irreversible trend. At the same time, intelligent technologies are rapidly and deeply integrating with the shipbuilding field. This transformation poses unprecedented challenges to ship network architecture. For example, the patent document with publication number CN 221448428U, publication date 2024-07-30, entitled "A Redundancy Architecture for Intelligent Ship Networks," discloses a redundancy architecture for intelligent ship networks, including a workstation, a server, an uninterruptible power supply, a first secure network router, a second secure network router, a first signal collector, a second signal collector, a miniature earth station, and a detector; the first and second secure network routers are mutually redundant, as are the first and second signal collectors; both the first and second secure network routers are connected to the workstation; and both are connected to the server.

[0003] However, the existing ship network architecture focuses only on the optimization of a single functional domain and lacks global collaborative design, making it difficult to adapt to the needs of multi-domain collaborative control; functional expansion relies on hardware modification, resulting in long software iteration cycles and high costs; the interface protocols of various devices are not unified, requiring conversion through protocol conversion gateways, which leads to high information delays and high hardware costs.

[0004] Therefore, this application proposes a ship intelligent collaborative network architecture and a ship. Utility Model Content

Furthermore, this invention constructs two Ethernet networks, one consisting of a main switch and the other a redundant switch, which operate independently and are backed up in real time.

The purpose is to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of this utility model, and to facilitate its implementation. It should be noted that the terms "first," "second," etc., used in this application are only for the convenience of describing the technical solution and distinguishing different components, and are not intended to limit this application. To make the technical solution of this utility model clearer, it will be explained and illustrated through the following embodiments.

[0020] This embodiment provides a ship intelligent collaborative network architecture, such as Figure 1As shown, the network architecture includes a cloud-edge computing domain, an intelligent driving domain, a power control domain, a navigation control domain, an energy management domain, and an Ethernet network for inter-domain communication. The intelligent driving domain, power control domain, navigation control domain, and energy management domain all have ship-side components. The cloud-edge computing domain includes a cloud-edge computing domain controller and a cloud server located in the cloud, and a ship remote receiving module located on the ship. The cloud server is connected to the cloud-edge computing domain controller; the ship remote receiving module is also connected to the cloud-edge computing domain controller. The ship remote receiving module receives control commands issued by the cloud-edge computing domain controller, and simultaneously collects local operational data from each domain of the ship, encrypts and uploads it to the cloud-edge computing domain controller, and then stores it in the cloud server. The cloud server is used for long-term storage and backup of ship operational data. The cloud-edge computing domain controller executes existing intelligent algorithms (including path planning, etc.) based on the data uploaded from the ship to generate control commands and issue them to the ship.

[0021] An Ethernet network is used to enable data interaction and collaborative control between the cloud-edge computing domain, intelligent driving domain, power control domain, navigation control domain, and energy management domain. For this purpose, each domain is equipped with a standardized Ethernet interface. Simultaneously, to achieve fast and accurate data exchange between domains, the Ethernet network includes a main switch. Within the Ethernet network, the ship's remote receiving module in the cloud-edge computing domain connects to the intelligent driving domain, power control domain, navigation control domain, and energy management domain respectively through the main switch.

[0022] Furthermore, the Ethernet network in this embodiment also includes a redundant switch, which serves as a backup for the main switch. Similar to the main switch, the ship's remote receiving module connects to the intelligent driving domain, power control domain, navigation control domain, and energy management domain via the redundant switch to form a redundant Ethernet network. In actual operation, the two Ethernet networks, consisting of the main switch and the redundant switch, operate independently and are backed up in real time. If either switch fails, the architecture immediately switches to the other switch, meeting the high reliability requirements of ship control.

[0023] The network architecture of this embodiment also includes a local server, which is connected to the intelligent driving domain, power control domain, navigation control domain, energy management domain, main switch, and redundant switch respectively. It is used to record real-time operating data of the entire ship at the ship end and can achieve dual data backup through synchronization with the data stored on the cloud server.

[0024] In this embodiment, the cloud edge computing domain, intelligent driving domain, power control domain, navigation control domain, and energy management domain are independent of each other but work together to form a complete intelligent ship management and control system, which meets the needs of ship functions in multiple scenarios.

[0025] The navigation control domain in this embodiment includes interconnected navigation domain controllers and navigation domain actuators. The navigation domain controllers are connected to the main switch, redundant switches, and local server. The navigation domain actuators include a control console and auxiliary navigation sensors.

In operation, the navigation domain controller collects commands from the ship's local pilots, sensor status, intelligent driving domain control commands, and cloud control commands. After arbitrating these commands, it issues corresponding commands to the power control domain and energy management domain.

[0026] The power control domain includes interconnected power domain controllers and power domain actuators. The power domain controllers are connected to the main switch, redundant switches, and local server. The power domain actuators include ship propulsion system equipment, ship transmission system equipment, and ship steering system equipment. Ship propulsion system equipment includes left / right motor drive controllers, ship transmission system equipment includes left / right transmission system controllers, and ship steering system equipment includes left / right rudder controllers. In operation, the power domain controllers in the power control domain can distribute power and torque across multiple power sources based on commands from the navigation control domain and the propulsion system, transmission system, and ship status.

[0027] The energy management domain includes interconnected energy management domain controllers and energy management domain actuators. The energy management domain controllers are connected to the main switch, redundant switches, and local server. The energy management domain actuators include battery management system equipment, power distribution system equipment, and battery swapping system equipment. In operation, the energy management domain controller can optimize energy and manage the battery based on its state, and control the power distribution circuit according to the load usage.

[0028] The intelligent driving domain includes interconnected intelligent driving domain controllers and intelligent driving domain actuators. The intelligent driving domain controllers are connected to the main switch, redundant switches, and local server. The intelligent driving domain actuators include intelligent driving system sensors (such as lidar, cameras, and millimeter-wave radar) and high-precision positioning system equipment. In operation, the intelligent driving domain controller fuses information from lidar, cameras, and millimeter-wave radar sensors, while simultaneously utilizing the high-precision positioning system to achieve functions such as path planning, intelligent decision-making, and active obstacle avoidance, and then issues commands to the navigation control domain.

[0029] In addition, each domain controller and each domain actuator are connected via a local control bus, which includes a CAN bus, a serial communication bus (RS485 / 422, etc.), and an Ethernet bus.

[0030] This embodiment also proposes a ship that includes the above-described intelligent collaborative network architecture for ships.

Specifically, these include: cloud-edge computing domain, intelligent driving domain, power control domain, navigation control domain, and energy management domain. Each domain is independent yet collaborative, forming a complete intelligent ship management and control system to meet the functional requirements of ships in multiple scenarios. Simultaneously, this network architecture also includes a high-performance local server for recording real-time operational data of the entire ship, while supporting data synchronization with the cloud-edge computing domain to achieve dual data backup.
