Shanghai Maritime University, Shanghai 200135, China) Abstract: Multiple navigational simulators and Multi-agent system technology are employed to construct the Vessel Automatic Collision Avoidance Simulation Platform(VACASP for short) on the platform of Microsoft Visual C++. A kind of communication net frame is proposed, which integrates the IOCP based on TCP/IP protocol with the broadcasting port based on UDP protocol. A kind of special protocol and relevant communication mechanism are also proposed in the application layer. The VACASP supplies interface for users to design and develop decision-making algorithm for automatic anti-collision by themselves. Based on his own research result of vessel automatic anti-collision, and adopting the object-oriented technique, the user can program all kinds of decision-making algorithms to form the Dynamic Link Library, and then integrate it to the VACASP. Finally he can carry out the simulation test for the decision-making algorithms utilizing the functions of console computer and ownship computers of the VACASP.
