Aiming at the long delay and high cost when water ship users monitor the underwater acoustic sensor networks, based on the characteristics of underwater acoustic sensor networks and VHF communication equipments commonly used in water ship users, we use embedded technology to design a water ship usersoriented gateway between underwater acoustic sensor networks and VHF communication networks, including its hardware and software systems. Simulation results show that the embedded gateway can realize the interconnection and communication between underwater acoustic sensor networks and VHF communication networks, which has a high theoretical and practical value.
