COASTGUARD, Security and surveillance
Security and surveillance for harbour areas, shallow waters and offshore installations
BUVI Scandinavia explains how EvoLogic's high-tech systems are ideal for the coast guard's operations by showcasing their advanced underwater communication and positioning systems in real-world scenarios. Through integrated solutions such as the Quadroin AUV, Sonobot 5 USV and the S2C USBL buoy enables precise tracking, navigation and communication for unmanned surface and underwater vehicles - essential tools for the Coastguard, search and rescue operations, surveillance and inspection missions.
Coastguard combines high-tech capabilities in the fields of
Data communication and underwater networks
Underwater positioning
Sensor systems
Object recognition and categorization
Deployment and mission support of underwater (AUV) and surface-based (USV) vehicles
ADVANCED UNDERWATER DATA NETWORK
Distributed underwater network for geo-referenced localization, which enables advanced navigation of multiple vehicles in the area
Advanced network protocols, such as relay chains and broadcasts for alarm messages
Enables a wide range of distributed underwater sensors, providing surveillance for critical infrastructure
HIGH-PRECISION UNDERWATER POSITIONING
Network can provide underwater positioning within a few centimeters of accuracy
Positioning network can support scalable AUV swarms and other underwater activities (e.g. divers)
Distributed network solutions with multiple fixed and floating network nodes possible
MULTI-STAGE AWARENESS OF OBJECTS IN THE AREA
Across the wider network structure, the COASTGUARD network will become aware of any objects both through passive monitoring of sound signals and periodic active pinging with directional tracking. In security level II zones (e.g., harbor entry, sensitive areas, around critical infrastructure), the deployment of active sensor nodes will enable 360° sonar imaging, video imaging and advanced listening capabilities for extra awareness and security. The Sonobot 5 USVs can perform regular active scans of the area, can recognize unknown objects and be aware of the changes compared to the previous scan.
AI-BASED OBJECT RECOGNITION AND ANALYTICS
Recognizes and identifies objects of interest through sonar scans, video images, and passive sound profiling
Categorizes objects based on neural networks
Identifies main object properties
Both stationary sensor nodes and mobile vehicles (USVs, AUVs) will be object recognition-capable
DETAILED INSPECTION AND TRACKING
In case of unknown or suspicious objects or suspected damages to the infrastructure, the operator is alerted and provided with an object-related digital file. The file contains all available scans and locations of the object or area.
The Sonobot 5 can be dispatched to locate and inspect the object from the surface (sonar scan) and follow its location/track. The Quadroin can be dispatched to create detailed underwater scans and video imagery.
NETWORK INFRASTRUCTURE
1. COASTGUARD COMMAND CENTER:
Mission control center which connects to all system modules, merges sensor data, communication, and positioning information in real-time. The Command Center recognizes and tracks objects, triggers alarms and provides relevant information on a central dashboard.
2. SEAFLOOR NODE, UNDERWATER NETWORK:
Acts as a node for an underwater
data network, provides USBL and LBL
positioning for moving underwater
objects, supports advanced network
protocols with more than 200 nodes,
will know its own absolute position once geo-referenced
3 MOBILE SURFACE NODE
(BUOY):
Acts as a surface-based node for an
underwater network, provides high-precision geo-referenced positioning for the underwater nodes, can create an own mobile network or flexibly extend an existing network
ADVANCED SENSORS
4. SENSOR NODE WITH OBJECT RECOGNITION AND ANALYTICS:
Recognizes and identifies objects of interest through sonar scans, video images, and passive sound profiling, categorizes objects based on neuronal network, identifies main object properties
5. ACOUSTIC SENSOR BUOY (USBL, HYDROPHONE)
Scans and recognizes sound profiles in passive listening mode including direction tracking, can actively ping and track objects in free water in active mode, multiple buoys can create a cross-referenced sensor network
6. SUPPORTED THIRD PARTY DEVICES
The system allows for flexible integration of proprietary sensors and/or third-party devices and vehicles. Sensors that deliver raw data can be enhanced by add-on A.I. modules that will provide object recognition and sensor fusion capabilities.
TARGET INSPECTION
7. SONOBOT 5 USV
Surface-based vehicle, patrols known and/or unknown shallow water areas, provides hydrography, provides A.I. based object recognition, can support underwater operations through surface-based inspection and mobile underwater data and positioning network
8. QUADROIN AUV
Autonomous underwater vehicle,
provides detailed sonar scans and video images of any object of interest, fully network capable to navigate in underwater data and positioning network, collision avoidance features included
9. UNDERWATER DOCKING STATION
Permanent underwater station that
acts as a garage for resident AUVs.
Underwater vehicles can access the
station, recharge, communicate via
cable-based data transfer and wait for
the next mission.
