基于激光测距的船舶防撞定位系统设计

Design of Ship Anti-collision and Position System Based on Laser Rangefinder Sensor

介绍一种基于激光测距的船舶防撞定位报警系统的设计原理,给出了系统的硬件设计和程序设计方法。在船舶上合理布置激光测距传感器,利用反射激光测量待测距离。实时自主的监测目标船舶与周围船舶的距离和方位,当进入待测领域的船只与目标船舶达到设定的安全距离时,实现声光报警,避免船舶相撞。由于整个系统的经济性和精确性,适合中小船舶的需求。

This thesis recommend the design principle of the system which preventing the ship colliding base on laser rangefinder sensor, gives systematic hardware design schematic and means of program design. In the ship exterior install these sensor reasonable, the system achieves to measure the distance between the ship and obstacle by detective laser that reflected by obsta cle. The system can auto and real time inspect the distance and position between the ship and obstacle around. If the measurement result is beyond the threshold, the system will give an alarm to avoid collision. This system is so economical and accurate that it satisfies the demand of middle or small marines.
