Research on Deep Sea Sonar in Marine Navigation of the Ship Anti Collision

摘要

in view of the current situation of ship has collision with sea mountain, Design and develop the sonar of ship collision avoidance system based on PLC. The main purpose is to remind the crew in front of mountains and ship automatic collision avoidance. The design is based on the minimum distance of ship and mountain, put forward the system scheme: measure the two objects distance by sonar, using this system as the control core, the information is analyzed and calculated by this system. When the distance between ship and mountains is less than the minimum safe distance. So this system will alarm crews and as deceleration avoidance.
