プロジェクト紹介


A top European defense contractor designing state-of-theart combat systems is leading the way in advanced networking for battleships using Ethernet over fiber. A battleship is comprised of many systems that act in unison to serve one purpose, which is to help a ship carry out its mission in the most efficient and reliable manner possible. Ethernet networks connect all main systems on a battleship, such as the main communications system, radar system, navigation, target ranging system, sonar, damage control and system status, power and electrical systems, monitoring systems, weapon systems, etc. Each major system has its own workstation to take care of calculations and data analysis. The Situation Room's main computer and servers are responsible for each major system's data. After analysis, each system's status is available to the Situation Room's control monitors. The Ethernet Network also includes data interchange services (gateways, routers and bridges) and mechanisms for interfacing bulk data storage devices.

 

System Description

 

The Ship's Combat System incorporates a distributed, computer-based system architecture integrated by means of a system of local area networks (LANs). For ultimate reliability, each sub-system is composed of a redundant LAN, with all LANs connected to a redundant primary Gigabit fiber backbone as well. LANs comprised of fiber technology offer great redundancy, high bandwidth, reliability, survivability and electromagnetic resistance. The systems on the battleship all operate in an real-time environment. Information from various systems is gathered and synchronized instantly for fast reaction speeds. For example, when an unknown contact appears, radar can detect the location of the target and send the information to the Situation Room. The Situation Room will control what combat system should be activated, adjust navigation, continue to gather more data and prepare battle systems. System response is considered synchronously in real time with the Ethernet network and Gigabit redundant backbone providing the main data transfer path.

 

Moxa products used include NPort Serial to Ethernet device servers to connect equipment like Radars or other devices such as PLCs to collect data. The PLCs use EDS-508-MM-SC Ethernet switches to connect to dual redundant local fiber ring topologies. Redundancy is critical in all these subsystems as well as the entire system architecture. These redundant subsystems are connected to the (EDS-726) dual Gigabit redundant Turbo ring of the ship that connects all systems with the Situation Room.

 

Since the battleship's combat system integrates nearly all functions of the battleship, the network used to exchange data needs to be extremely fast, reliable and robust. With a dual-fiber ring topology network architecture, if one of the networks is damaged, the other network will act normally to back up the damaged element. In addition, the high bandwidth of the fiber Gigabit ring can completely satisfy the long distance and high transmission demands of a combat system. The system has to also be user-friendly, affordable, efficiently maintained, expandable and upgradeable. In short, a combat system must have the design and rugged components to ensure 100% readiness.
