Smart Fishing Vessel Supervision Integrated Communication and Command Dispatch

I. Maritime Communication Methods

1.1 Nearshore 4G LTE Communication

Utilizes 4G LTE base stations on land or offshore islands to communicate with 4G terminals onboard vessels.

1.2 Satellite Communication

Enables region-unrestricted maritime satellite communication via the BeiDou satellite system, communicating with BeiDou terminals onboard vessels to transmit short messages, positioning information, etc.

1.3 Radio Communication

1.3.1 Coast Station

A coast station serves as a "relay" connecting vessels and land-based communication. It broadcasts maritime safety information such as weather, typhoon warnings, and navigation warnings to vessels, and also provides relay services for navigation, commercial, and personal messages between vessels and shipping companies. More importantly, it listens around the clock for distress messages from the sea, providing uninterrupted safety protection for vessel voyages.

1.3.2 Ship Station

A ship station is radio equipment installed onboard a vessel for communication purposes. Depending on the vessel's size and application, the functions and performance of ship stations vary. They can support long-distance or short-distance communication.

1.3.3 "Floating Island" Station

These are man-made offshore installations such as navigation marks indicating channel boundaries, shoals, or obstructions, or observation stations collecting ocean tide and seawater temperature data, or monitoring water quality and pollution conditions. To identify these waterborne objects, a radio station is installed on them to alert passing vessels. This device is also known as an autonomous maritime radio transmitting equipment.

1.3.4 Radio Station "ID Card"

For easier vessel identification, just like a person's name or a mobile phone number, each vessel is assigned a globally unique 9-digit Maritime Mobile Service Identity (MMSI). It is bound to useful information such as the vessel's name and owning company. When a vessel is in distress at sea, the crew uses the ship station to transmit a message carrying this identity. When maritime rescue coordination centers in various countries receive the message containing the identity, they can retrieve vessel information by comparing it with their databases, enabling better organization of search and rescue operations.

1.4 UAV Communication

For vessels within the reachable range of offshore UAVs, UAVs can be used for wireless relay communication, providing wireless network coverage to vessels through wireless MESH self-organizing network coverage. UAVs can also carry video equipment for aerial video surveillance operations.

II. Integrated Communication Command Dispatch

2.1 Shore-to-Sea Integrated Communication Command Dispatch

The shore-based command center performs integrated communication command dispatch for vessels and personnel at sea, including BeiDou positioning and tracking, voice communication, text message communication, radio intercom communication, video surveillance and backhaul, and abnormal alarm functions.

2.2 Mobile Integrated Communication Command Dispatch

A maritime command vessel serves as a mobile command center to perform integrated communication command dispatch for vessels and personnel at sea, including BeiDou positioning and tracking, voice communication, text message communication, radio intercom communication, video surveillance and backhaul, and abnormal alarm functions.

2.3 Multimedia Integrated Command

Achieves organic integration of multiple business systems including voice dispatch, video dispatch, IoT dispatch, GIS dispatch, inspection and patrol, emergency plans, and work order management.

2.5 Vessel Abnormal Alarm and Linkage

(1). Through BeiDou positioning and electronic fence alarm, detect suspicious violations such as equipment shutdown, shielding, dismantling, anchoring in channels or anchorages, cross-boundary fishing, fishing during moratorium periods, and fleet formation alerts.

(2). Based on AIS positioning system data, perform data fusion analysis to locate our vessels and foreign vessels and generate abnormal alarms.

(3). Based on radio station positioning, provide abnormal alarms.

(4). UAV patrol to detect abnormal alarms and report.

(5). Video surveillance and monitoring from offshore high-ground vantage points.

u Target Detection: Through the application of technical services, achieve automatic patrol and snapshot capture to detect targets.

u Target Identification: Identify whether targets are illegal through key technologies such as video structured analysis and multi-source target fusion.

u Alarm Generation: Automatically generate alarms by determining whether targets cross electronic fences, enter custom defense zones, or engage in illegal activities. Alarm information can be sent in real time to PC terminals and law enforcement officers' mobile clients.

u Linked Tracking: Technical services automatically capture, identify, and record illegal vessels through equipment patrol, while also serving as a deterrent and warning.

u Law Enforcement Disposal: On-site law enforcement personnel can quickly locate and find targets based on target position information collected by front-end equipment. The remote command center can conduct collaborative remote command through large screens, achieving comprehensive control of law enforcement operations.

u Evidence Preservation: The alarm system archives vessel movement trajectories, captured images, and video information. Data storage duration can be configured as needed, with important stored data retained on demand and permanently valid. Synchronized playback of target data and video is supported.

2.6 System Functions

2.6.1 Voice Dispatch Function

The voice dispatch function mainly includes all basic communication and supplementary service functions of softswitch communication, common dispatch functions, dispatch conference functions, recording, SMS, fax, system management, dispatcher management, and other related functions. The console supports command dispatch for the following types of communication terminals.

2.6.2 Video Dispatch Function

The integrated video dispatch module mainly implements the access of various video sources, and through the video server, achieves transcoding, mixing, and forwarding of various video sources. Accessed video sources include video surveillance systems, video conferencing systems, individual soldier systems, broadband trunking terminals, and video phones.

2.6.3 GIS Dispatch Function

The system can be linked with existing GIS systems. Combined with the actual business needs of industry users for command dispatch, it fully utilizes the intuitive display capability of GIS to centrally command and uniformly control various multimedia resources and devices based on maps. It integrates geographic information of the areas of greatest concern to commanders, video surveillance points, and positioning information with the comprehensive emergency command platform, facilitating commander operations and enabling multimedia command dispatch such as voice dispatch and video surveillance viewing, maximizing the role of the comprehensive emergency command platform and improving the work efficiency of center staff.
