Description

Technical Field

[0001] This utility model relates to the field of intelligent ship technology, specifically to an intelligent ship management and monitoring system. Background Technology

[0002] In recent years, intelligent ships have become a new hot topic in the international maritime community. International organizations such as the International Maritime Organization (IMO) and the International Organization for Standardization (ISO) have listed intelligent ships as an important issue, and major international classification societies have successively issued specifications or guidance documents related to intelligent ships. Major shipbuilding countries worldwide are vigorously promoting the research and application of intelligent ships. In the context of the information age and big data, ship intelligence has become an inevitable trend in the development of shipbuilding and shipping. Due to the needs of international trade and maritime transport development, ship automation technology has evolved from single-device control to system integration, but existing ship monitoring systems still have three major shortcomings:

[0003] 1. Subsystems operate independently, resulting in severe data silos: Subsystems such as ship main engine monitoring, video surveillance, and ship management are mostly deployed independently, using different communication protocols (such as CAN for the main engine and TCP / IP for video), and there is no unified data interaction interface. This forces crew members to switch between multiple terminals, making it impossible to achieve linkage analysis between equipment malfunctions and video footage.

[0004] 2. Insufficient real-time monitoring capabilities at shore: Existing systems rely heavily on satellite phones or traditional 2G / 3G networks to transmit data, which can only transmit a small number of key parameters (such as engine speed) and cannot achieve real-time transmission of video streams and full equipment data. As a result, shore-based companies have difficulty keeping abreast of sudden ship emergencies (such as equipment failures or cabin smoke).

[0005] 3. Low intelligence in fault early warning and maintenance management: Equipment fault detection relies heavily on "threshold over-limit alarms" and lacks historical data trend analysis functions, making it impossible to predict potential faults in advance (such as bearing temperature rise caused by bearing wear); Ship management (such as spare parts inventory and maintenance plans) is disconnected from equipment operation data, which easily leads to problems such as "delayed maintenance" or "spare parts redundancy".

[0006] In summary, existing systems can no longer meet the management requirements of intelligent ships in terms of "real-time performance, integration, and predictive capabilities," and there is an urgent need to design an intelligent monitoring system that integrates all dimensions and enables real-time ship-shore interconnection. Utility Model Content

[0007] To address the shortcomings of existing ship monitoring systems, such as "data silos, poor real-time performance at the shore end, and weak early warning," this utility model provides an intelligent ship management and monitoring system. Through hardware system integration, high-speed data transmission, and intelligent early warning mechanisms, it achieves comprehensive monitoring and ship-shore collaborative management of ship equipment, navigation status, and ship affairs management.

[0008] The technical solution adopted by this utility model is as follows: an intelligent ship management and monitoring system, including an intelligent shore-based management and monitoring system and several sub-intelligent ship management and monitoring systems. The intelligent shore-based management and monitoring system and the several sub-intelligent ship management and monitoring systems establish a real-time communication link through a data interaction system, wherein the sub-intelligent ship management and monitoring system is the core execution layer and the shore-based management and monitoring system is the remote monitoring layer.

[0009] Furthermore, the intelligent ship management and monitoring system includes a ship digitization system, a communication and navigation system, a ship management system, a video management and monitoring system, and a data interaction system. These systems are interconnected via industrial Ethernet (Profinet protocol) and CAN bus.

[0010] Furthermore, the ship digitalization system, communication and navigation system, ship management system, video management and monitoring system, and data interaction system in the intelligent ship management and monitoring system are all connected to the display terminal in the ship's main control room.

[0011] Furthermore, the intelligent shore-based management and monitoring system, deployed in the monitoring center of the shipping company, includes a data receiving server, a visualization platform, and an alarm management module. It can receive equipment data, video streams, and navigation trajectories transmitted from the ship's display terminal in real time, and generate operation reports and fault analysis reports.

[0012] Furthermore, the ship's digital system comprises a data acquisition module, a signal conditioning circuit, a data processing unit, and a threshold alarm module. The signal conditioning circuit includes a TVS diode for lightning protection and an RC filter sub-circuit. The threshold alarm module includes a buzzer and a red LED alarm light. The data acquisition module connects to the signal conditioning circuit, which in turn connects to the data processing unit. The data processing unit connects to the display terminal, which in turn connects to the threshold alarm module. The data acquisition module is electrically connected to sensors in the ship's main engine, power station, propulsion unit, and shafting. It can collect equipment operating parameters (speed, temperature, pressure, etc.), which are converted by the data processing unit and output to the display terminal. When a parameter exceeds a preset threshold, the threshold alarm module triggers an audible and visual alarm.

[0013] Furthermore, the communication and navigation system consists of a GPS device and a multi-protocol communication module; the GPS device is connected to the display terminal, and the multi-protocol communication module is connected to the intelligent shore-based management and monitoring system, the ship digital system, and the ship management system, respectively.

[0014] Furthermore, the ship management system consists of an equipment management module, a maintenance module, a material management module, and a crew management module.

[0015] Furthermore, the video management and monitoring system includes video equipment and thermal imagers; the video equipment covers key areas of the ship, and the video equipment and thermal imagers are connected to display terminals.

[0016] Furthermore, the data interaction system includes a 4G / 5G communication module and a communication satellite. The data interaction system establishes a real-time data transmission link with the shore-based management system through the 4G / 5G communication module and the communication satellite.

[0017] The beneficial effects of this utility model are as follows: The ship digital system, based on a data acquisition module and a threshold alarm mechanism, completes the acquisition, display, and anomaly alarm of the operating status of core equipment such as the ship's main engine and power station; the communication and navigation system integrates GPS positioning and multi-protocol communication (CAN / TCP / RS485) to realize equipment data transmission and ship navigation; the ship management system covers core ship management functions such as equipment management and maintenance with a modular design; the video management and monitoring system is equipped with video equipment and thermal imagers to realize full-area visual monitoring and anomaly alarm of the ship; the data interaction system establishes a real-time data transmission link between the ship and the shore through a 4G / 5G private network, enabling the shipping company to remotely and in real time grasp the ship's shipping status and equipment operating conditions.

Detailed Implementation

[0020] like Figure 1 As shown, the technical solution adopted by this utility model is as follows: an intelligent ship management and monitoring system, including an intelligent shore-based management and monitoring system and several sub-intelligent ship management and monitoring systems. The intelligent shore-based management and monitoring system and the several sub-intelligent ship management and monitoring systems establish a real-time communication link through a data interaction system, wherein the sub-intelligent ship management and monitoring system is the core execution layer and the shore-based management and monitoring system is the remote monitoring layer.

[0021] Detailed design of each subsystem; Ship digital system (3): Hardware composition: customized data acquisition module, signal conditioning circuit (including TVS tube lightning protection and RC filter sub-circuit), data processing unit, threshold alarm module (including buzzer and red LED alarm light); Function implementation: The data acquisition module collects parameters such as the main engine (10) speed, power station (11) output voltage, power unit (12) oil pressure, shaft system (13) temperature, etc. through current / voltage sensors. After the signal conditioning circuit filters out interference, it is transmitted to the data processing unit and converted into digital signals. The display terminal displays the parameters in real time in the form of instrument panel and curve. When the parameters exceed the preset threshold, the threshold alarm module triggers the sound and light alarm and synchronizes the alarm information to the ship management system (5) and shore management system (1).

[0022] Communication and Navigation System (4): Hardware Components: GPS device (14), multi-protocol communication module (15); Functional Implementation: The GPS device (14) outputs the ship's latitude, longitude, speed, and heading in real time, and displays the navigation trajectory on a GIS map overlaid on the display terminal; the multi-protocol communication module (15) acts as a data transfer hub, transmitting the equipment data of the ship's digital system (3) to the ship management system (5), and simultaneously receiving control commands (such as adjusting alarm thresholds) issued by the shore management system (1). The GPS device (14) can output the ship's real-time position and navigation trajectory, and the multi-protocol communication module (15) supports CAN, TCP, and RS485 protocols, enabling data interaction between the ship's digital system (3) and ship equipment.

[0023] Ship Management System (5): Hardware Composition: Industrial-grade server, touch-screen operation terminal; Function Implementation: Based on modular software design, it includes four core modules: Equipment Management Module (16): Stores factory parameters and maintenance records of ship main engine, power station and other equipment, associates with real-time data of ship digital system (3), and generates equipment health score (based on indicators such as speed fluctuation and temperature rise trend); Maintenance Module (17): Automatically generates maintenance plan based on equipment running time (such as main engine running for 1000 hours) or health score, pushes it to crew mobile terminal, and records maintenance results; Material Management Module (18): Real-time statistics of spare parts inventory (such as bearings, filter elements), triggers replenishment reminder when inventory is lower than the safety threshold, associates with spare parts warehouse information of shore management system (1), and supports remote purchase; Crew Management Module (19): Stores crew electronic files (qualification certificate, health record), automatically reminds of certificate validity period, and records crew duty schedule information. The ship management system (5) includes an equipment management module (16), a maintenance module (17), a material management module (18), and a crew management module (19). Each module communicates with the ship digital system (3) through a data interface, and can obtain equipment operation data and generate maintenance plans.

[0024] Video Management and Monitoring System (6): Hardware Components: Video equipment (20), thermal imager (21), video storage server; Functional Implementation: The video equipment (20) covers 6 key areas including the ship deck, engine room, and main control room. The video images are transmitted to the display terminal in real time, supporting split-screen viewing and historical playback; The thermal imager (21) performs non-contact temperature measurement on high-temperature equipment such as the main unit and power station. When a local temperature rise is detected to exceed the normal range (such as a bearing temperature rise ≥ 40℃), the video analysis unit is triggered to alarm and automatically retrieves the panoramic camera image of the area and synchronizes it to the shore management system (1). The thermal imager (21) can detect abnormal temperature rise of equipment, and the video analysis unit can identify scenes such as smoke and abnormal personnel movement and trigger alarms;

[0025] Data Interaction System (7): Hardware Components: 4G / 5G Communication Module (8), Communication Satellite (9); Functional Implementation: As the core channel for ship-to-shore data transmission, the equipment data and GPS trajectory on the ship are encrypted and transmitted to the shore management system (1) through the 4G / 5G private network; When the ship sails to an area in the open ocean where there is no 4G / 5G signal, it automatically switches to the communication satellite (9) to transmit key data (such as alarm information and GPS location) to ensure that the data is not interrupted.

[0026] The working principle of this utility model is as follows: Data acquisition and processing: The acquisition module of the ship digital system (3) collects equipment parameters in real time, and outputs them to the display terminal and each subsystem after processing; The communication and navigation system (4) outputs GPS trajectory, and the video management and monitoring system (6) collects video and temperature measurement data; Local monitoring and alarm: If the equipment parameters exceed the standard or the video recognition is abnormal, the ship digital system (3) and the video management and monitoring system (6) trigger the sound and light alarm simultaneously, and the display terminal pops up an alarm pop-up window to indicate the abnormal location and cause; Ship-shore data interaction: The data interaction system (7) transmits equipment data, video streams, and alarm information to the shore management system (1) through 4G / 5G or satellite; Shore-side remote management: The shore management system (1) displays the ship's location on the GIS map, views equipment data and video in real time, and can issue instructions (such as guiding crew members to troubleshoot faults) after receiving alarm information; The ship management system (5) generates a maintenance plan based on the equipment data and records it on the shore simultaneously.
