Abstract :
Based on the analysis of the indetermination of rule definition and shortcomings of communication equipments currently used for collision avoidance, a collision avoidance coordination system using the VHF communication device with Racon at sea is established, and the schematic diagrams of two sub-systems of this system are presented. The coding principle of radar answer signals is also established. The system can effectively overcome the indetermination of collision avoidance, effectively combine both audio and vision, so that both parties can know the position and avoidance intention of the coming ship at any time, and produce a good avoidance result. Using this system, the ship can exchange information automatically because the information can go through between PC and VHF modem digitally.
