| Abstract: | This paper selects 82C250 as the interface between the CAN-bus controller and physical layer, provides differential transmission and reception through CAN-bus controller, and establishes network distribution equivalent circuit based on CAN-bus, and the largest length of bus and the number of nodes can be deduced. Thus, it provides a theoretical basis for vessel monitoring system. It can accurately estimate the length and the maximum number of nodes, and rapidly detect and exclude operational failures, and improve the safety and reliability of the system. |
