DATA TRANSMISSION AND HANDLING SYSTEMS FOR SHIPBOARD APPLICATIONS

Automated systems are based on the following principles: the great volume of data available and the possibility of correlating it at very short intervals. The problem of communications on board, and particularly in naval craft, is examined from several points of view: investment, maintenance, weight, volumes, flexibility, security against failure and electro-magnetically polluted environments. The traditional solution is to have a number of point-to-point links, one wire for each signal, with a consequent waste of space and weight. Metallic cables also create problems of electro-magnetic interferences, insulation and earthing. This paper proposes a solution which takes into account the problems of data communication as a whole; it is based on a time-division multiplex and data bus, transmission through optical fibres, and the use of micro-processors and distributed control. The system comprises a variable number of access units; users and sources have access to the network through a digital interface, the data being multiplexed, processed and forwarded in the proper direction. All access units are interconnected in a loop system through optic fibre links with a redundancy of alternative paths.
