Design of a Gateway for Remotely Underwater Vehicles

A gateway based on ARM is presented to achieve mutil-protocol conversion among different electronic control units. To guarantee its real-time ability and stability, the μC/OS-II embedded operation system was adopted. The first-in-first-out data queue is used to balance the communication rate among the different communication protocols which consist of the Controller Area Network, TCP/IP and RS-232. The gateway can be used in remotely manipulation between the console with Ethernet and remote underwater vehicle with other serial communication protocols.
