Distributed Sensor Network for Submarines
Contact us today to find out more about how we can help build your submarine distributed sensor network.
A submarine is a sealed environment in which the crew are working and living for periods of up to 90 days. Tthe atmosphere inside needs to be continually monitored and managed to limit exposure of the crew to potentially harmful substances and to ensure the atmosphere is capable of supporting life when the submarine is submerged.
A distributed sensor network comprises a centrally located PLC user interface linked to discrete gas sensors or sensor modules located around the boat. Typical gases monitored include oxygen (O2), carbon dioxide (CO2), carbon monoxide (CO) and hydrogen (H2), in addition to refrigerant gases, submarine pressure and humidity.
This system is ideal for diesel boats which need to monitor life-support gases and contaminants to MPC60 minute and MPC24 hour limits but may have limited space.
A distributed sensor network offers:
- Flexible system architecture
- Any number of sensors, or integrated sensor blocks can be connected to the central display
- Sensors can be tailored to suit the requirements of the customer, updated throughout the boat's life as requirements or technology advances
- HMI repeater displays located in different locations on the boat
- Optional uninterruptable power supply (UPS) for emergency use
- Sensors located in the area where the gas poses a direct risk
- Central display of information from all remote sensors
- Password protected 'Admin' mode for data logging and data retrieval via USB port
- Data output to central submarine platform management system
