5. Positioning and Data Transmission

• The monitoring center can track the vessel's current position, moving speed, moving direction, and other conditions at any time;
• Vessel positioning can be monitored in multiple modes including positioning, timing, fixed distance, fixed speed, fixed route, fixed range, and fixed location;
• Functions include single-point positioning, continuous monitoring, and key target tracking monitoring;
• The system interface displays the monitoring status of vessels;
• Vessel positioning adopts dual BeiDou and GPS positioning, also supporting GPS-only positioning and BeiDou-only positioning to ensure positioning accuracy;
• Vessel terminals use 3G/GSM networks to transmit data information to the central platform, supporting manual and automatic transmission of the vessel's current position information.
  6. Track Playback
• The monitoring center intuitively displays the vessel's position and navigation track on the electronic map;
• The database can be queried at any time to play back the navigation route track of a designated vessel within a set time period, and track playback data can also be exported;
• The vessel terminal has built-in historical track storage, capable of storing 30,000 track points when the vessel is in network blind areas.
  7. GIS Functions
• Image map display

The vector map can be overlaid with other image maps, such as satellite photos and aerial photos.
8. Map Unlimited Zoom
The map supports unlimited zoom, with operation methods including clicking the map to zoom in/out by one level, selecting a region on the map to zoom in/out to display the entire region, and zooming in/out to a specific scale. The entire zooming process is smooth and flicker-free.
9. Layer Control
Through the layer manager, it can control whether a certain layer on the map is displayed and whether it can be queried.
10. Information Annotation
Information points can be annotated on the GIS electronic map, and information points support entry, editing, and modification according to permissions.
11. Video Surveillance System
The Beijing headquarters command center utilizes the functions provided by this system to conduct video surveillance over the command centers of various sea area headquarters and maritime surveillance vessels. It enables flexible switching of on-site images, remote control of remote camera pan-tilt units, and convenient combined display of multiple video channels.
The command centers of various sea area headquarters conduct video surveillance over maritime surveillance vessels within their respective jurisdictions. It enables flexible switching of on-site images, remote control of remote camera pan-tilt units, and convenient combined display of multiple video channels.
Users can flexibly switch on-site video images, control pan-tilt units and cameras, conveniently combine and display multiple video channels, and support two-way voice video intercom.
12. Video Command & Dispatch
With the multiple levels and permission mode settings unique to the remote video command & dispatch system, duty personnel at the Beijing headquarters command center can issue instructions and commands to the command centers of various sea area headquarters or maritime surveillance vessels through command & dispatch terminals. Real-time two-way audio and video information exchange can be conducted between superior and subordinate departments, and between leaders at all levels and their subordinates.
13. Video Conference
The Beijing headquarters command center uses this system to organize traditional video conferences, conducting two-way audio-video exchange and interaction with the command centers of various sea area headquarters and maritime surveillance vessels. Conference organizers can set up multiple regular meetings, each containing relatively fixed members, making it convenient to organize meetings. Meeting members can join and leave the meeting group at any time. The conference organizer can control the speaking rights of each venue and broadcast a certain sub-venue.
The system supports multiple conference formats: instant conferences, regular meetings, and multiple conference groups.
Video conferences can be held as needed to conduct various meetings such as shift handover meetings, coordination meetings, and summary meetings, enabling multi-point, multi-party two-way audio-video exchange and interaction.
14. System Management Configuration
User management: user identity authentication, user level and permission setting management.
Device management: terminal address resolution; terminal parameter configuration, such as configuring terminal type, level permissions, codec address, multicast address, and video switcher type; real-time monitoring of the working status of each terminal; network video matrix access control; video recording server access control.
System management: automatic switching between unicast and multicast, business function logic scheduling control.
15. Multiple Level Permission Settings
User permission management defines three permissions over other terminals: command authority, monitoring authority, and control authority. During system configuration, flexible permission settings can be made according to actual affiliation relationships. In case of contention, higher levels take priority; at the same level, earlier time takes priority.
