[0036] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.
[0037] Please refer to Figure 1 and Figure 2 , which is a structural block diagram of a ship control system provided in an embodiment of the present application, the ship control system includes a central control system located in the cab, a first acquisition system located at the bow, a second acquisition system located at the stern, and a display system located at the console.
[0038] The central control system includes a master control equipment box, a first network switch, a second network switch and an extended alarm panel. The first acquisition system, the second acquisition system and the display system are connected to the master control equipment box through the first network switch and the second network switch respectively.
[0039] The first acquisition system is used to collect the operating information of each bow device located at the bow of the ship and transmit the operating information to the master control equipment box.
[0040] The second acquisition system is used to collect the operating information of each stern device located at the stern of the ship and transmit the operating information to the master control equipment box.
[0041] The extended alarm panel and display system are used to execute an alarm when receiving an alarm message sent by the master control equipment box.
[0042] In this embodiment, the master control equipment box can be a SIAS (Integrated Automation System) equipment box. The SIAS equipment box can be understood as a new navigation aid system used for maritime safety and communication between ships and shore, and between ships. The first network switch and the second network switch can be optoelectronic switches. Optoelectronic switches use optical fiber cables as a transmission medium and have advantages such as high speed and strong anti-interference capabilities. Optoelectronic switches are data exchange devices that exchange optical signals directly, eliminating the need for electrical-to-optical conversion. This significantly increases the exchange rate.
[0043] In this embodiment, the first network switch and the second network switch adopt a one-master-one-standby working mode, that is, when the first network switch is in a normal working state, the first network switch realizes information transmission.
[0044] When the first network switch fails, the information transmission is automatically switched to the second network switch. When the first network switch recovers to normal working state, the information transmission is switched to the first network switch.
[0045] In this embodiment, based on the one-master-one-backup operation mode of the first network switch and the second network switch, stable operation of the system is ensured.
[0046] In this embodiment, the first and second acquisition systems and the display system are connected to the first and second network switches via optical fiber transmission, significantly improving data transmission speed and reliability. Furthermore, to ensure stable operation of the communication system, a redundant power supply system is provided in this embodiment to ensure normal operation of the communication system in the event of an unexpected situation.
[0047] Each functional module, such as the first and second acquisition systems, transmits information to the optoelectronic switch via the MODBUS-TCP protocol, enabling rapid information transmission and processing. The MODBUS-TCP protocol is a communication protocol widely used in industrial control. It enables data exchange between devices over a TCP / IP network and uses TCP to ensure reliable data transmission.
[0048] In this embodiment, the central control system includes not only the master control equipment box, the first network switch, the second network switch and the extended alarm panel in the cab, but also switches, power supplies and other equipment located in the cab.
[0049] The display system located at the driving console may include display panels, and the number of display panels may be two, three, etc.
[0050] The extended alarm panel, display panel, etc. are connected to the master control equipment box. When the master control equipment box generates an alarm message, the extended alarm panel can execute an alarm based on the alarm message, so that it is convenient for the crew to view the alarm message. In addition, the display panel can also execute an alarm based on the alarm message, and various related alarm data can be displayed through the display panel to facilitate the crew to understand the detailed abnormal situation.
[0051] In this embodiment, the extended alarm panel is a key device in the alarm system, which can be used to transmit alarm signals over long distances, achieve comprehensive monitoring and timely alarm. The extended alarm panel is composed of precision accessories such as a controller, extension cables, and converters.
[0052] In a control system, sensors within the data acquisition system monitor the area's status in real time and notify the master control box when an anomaly is detected. However, if the area is large, the master control box's signal transmission capacity is limited, which is when an extended alarm panel comes into play.
[0053] Extended alarm panels connect to other devices via extension cables, transmitting alarm signals to further locations. Multiple extended alarm panels can be connected to the master control box to create a comprehensive alarm system. When a sensor detects an anomaly, the master control box quickly processes the signal and relays it through the extended alarm panels, ensuring prompt and accurate alerts throughout the monitored area.
[0054] In the ship control system provided in this embodiment, the combination of the extended alarm panel, the display system and the acquisition system can achieve rapid monitoring and response to faults, thereby improving the monitoring timeliness and early warning timeliness of the control system.
[0055] In addition, in this embodiment, the master control equipment box is also used to transmit the received operating information and generated alarm information to the shore-based monitoring center in real time via the MODBUS-TCP protocol. This makes it convenient for shore-based management personnel to monitor the ship's status in real time.
[0056] In this embodiment, the control system, in addition to the master control cabinet serving as a centralized control cabinet and the layout of various acquisition systems serving as remote monitoring terminals, also employs an intelligent data analysis solution to enable real-time diagnosis and predictive maintenance of the ship's operating status, proactively identifying and resolving potential faults and hidden dangers, thereby improving the safety and efficiency of ship operations. All monitoring data can be uploaded to a shore-based monitoring center in real time via the MODBUS-TCP protocol, enabling management to fully understand the ship's operating status and conduct remote control and optimization.

[0059] In this embodiment, the collected operation information of the bow propulsion control system can be transmitted to the first network switch and the second network switch through the MODBUS-TCP protocol.
[0060] The Automatic Identification System (AIS) is an automatic reporting system used for ship tracking that provides a ship's identification, position, speed, course, and other relevant information.
[0061] A depth sounder is a marine instrument used to measure underwater depth. It calculates the water depth at the ship's location by sending sound wave signals to the bottom of the water and then receiving the echoes reflected by these sound waves.
[0062] The odometer on a ship is an instrument used to measure the distance a ship has traveled in the water. The satellite compass on a ship can calculate the ship's precise position, speed, and heading by receiving signals from multiple satellites.

[0064] Furthermore, steering gear is a device used on ships to change their course. It can be divided into electric steering gear and hydraulic steering gear. Flood alarms can be used to detect flooding, while fire alarm systems can be used to detect fires.
[0065] In this embodiment, the servo, water inlet alarm equipment, fire alarm system, etc. can be connected to the protocol converter, such as MTTR, via the MODBUS-RTU (a serial communication protocol) protocol, and then connected to the first network switch and the second network switch via the MODBUS-TCP protocol.
[0066] In this embodiment, the first data collection system can collect operating information from each bow device and transmit it to the master control box. Upon receiving the operating information, the master control box can generate an alarm message if it detects an anomaly. The extended alarm panel in the bridge cab can also generate an alarm based on the alarm information. Furthermore, the display system in the bridge console, such as the display panel, can also generate an alarm based on the alarm information.

The second acquisition system includes an upper stern signal box, an stern engine room signal acquisition box, an upper stern extended alarm panel connected to the upper stern signal acquisition box, and an extended stern engine room alarm panel connected to the stern engine room signal acquisition box.
[0069] Among them, the stern upper signal acquisition box and the stern engine room signal acquisition box can be connected to the data server through the CAN bus respectively, and then connected to the first network switch and the second network switch through the MODBUS-TCP protocol.
[0070] The stern upper extension alarm panel and the stern engine room extension alarm panel are respectively connected to the protocol converter via the CAN bus, and then connected to the first network switch and the second network switch via the MODBUS-TCP protocol.
[0071] In this embodiment, the stern equipment includes a power management system, a left main propulsion control system, a right main propulsion control system, a battery compartment battery replacement device, and a battery compartment battery system.
[0072] The battery compartment battery swapping system includes a battery swapping robot, a DBOX (battery exchange box), and an electricity meter. The DBOX is connected to the battery, providing a container for storing and swapping batteries. The electricity meter is connected to the battery, measuring the battery's power consumption during charging and discharging. Under control, the battery swapping robot performs battery swapping operations according to the corresponding battery swapping mode and parameters.
[0073] In this embodiment, the battery compartment battery replacement device can realize online control of the battery replacement robot, including battery replacement start and stop operations, online control of the battery replacement robot mode, and online parameter update of the battery replacement robot.
[0074] The control methods for the battery-swapping robot can include local control and remote control. Among them, the local control method is mainly based on maintenance and management, including battery relocation, bottom support and unlocking control, etc., while the remote control method is mainly based on automatic battery-swapping control.
