Design of Ship Communication System Based on CAN Bus

Existing ship electronic equipment are based on serial interfaces in accordance with NEMA0183 Protocol for the exchange of information, complex low transfer rates, lines, nodes exist, poor reliability shortcomings. Fieldbus (CAN) to its high anti-interference ability and higher traffic rates made up for these shortcomings, has been widely applied to automotive electronics, but in application of ship data communication has not been very good. CAN bus technology with outstanding reliability, timeliness and flexibility for the development of modern marine communication system offers a new way.
