Application Case | Vessel AIS data acquisition system
The shipboard comprehensive monitoring system integrates radar, AIS, CCTV, GPS, and other detection technologies, along with highly integrated real-time situational awareness and cognitive technologies, to effectively monitor the vessel and vessels within the vicinity. It extends the supervision range of shore-based monitoring centers, ensuring navigational safety and providing various technical means for maritime safety management authorities to achieve shore-based controllable data communication and dynamic data acquisition.
Customer application requirements
The vessel data remote acquisition controller is a MEC device used as onboard equipment to realize ship-shore data communication control, as well as the collection of vessel navigation data, engine room working condition data, maritime meteorological data and vessel AIS data. It is a key equipment for the maritime safety management authorities to realize shore-based controllable data communication and dynamic data collection.
A large domestic land and marine equipment company approached us and hoped that we could provide it with reliable hardware support equipment. Specific requirements for the MEC device include:
- Adopting the AIoT (General CPU + AI Computing GPU) architecture schemeand an open system platform, it can perform multi-task management and control such as device access, data collection, parallel computing, network communication, early warning output, display interaction and storage;
- Comprehensive I/O interface allows access to multiple sensors (cameras and radars) and serial port acquisition modules;
- Dual-channel mutually redundant GPRS/3G/4G wireless network functions ensure remote communication between ship, shore and ship;
- Internal electronic components and PCBmust be coated with three-proof coating to adapt to the high humidity and corrosive climate environment at sea;
- Reinforced structural shell, moderate size, easy installation, suitable for shipboard applications;
- Shipboard MEC needs to comply with the IEC-60945 international ship navigation electronic equipment standard;
- Wide-voltage power supply adapts to the complex and changeable power supply environment onboard ships.
