摘　　要：浮式系船柱作为船舶过闸的系缆设备被广泛应用,但由于船舶系缆程序不规范、船舶吨位增大导致系缆力超载等问题,导致浮式系船柱卡阻或升降迟缓,带来严重的安全隐患。提出基于激光测距和离群点检测的浮式系船柱运行状态检测方法,利用激光测距技术实时获取浮式系船柱的高程,融合K-means聚类算法和IQR四分位算法对所有浮式系船柱高程数据点进行离群点检测,以确定浮式系船柱是否存在运动卡阻等问题。构建基于串口服务器的高程实时采集硬件电路,采用Qt平台开发高程数据采集和系船柱状态分析上位机软件,实现浮式系船柱运行状态的自动检测与预警。现场测试结果表明:系统在室外环境中运行平稳可靠,能够实时采集浮式系船柱的高程并完成分析,通过人机交互界面进行显示,为浮式系船柱运行状态实时检测提供了实用可行的方法。Floating bollards are widely used as the mooring equipment for ships passing through ship locks,but there are problems such as non-standard mooring and overload of mooring force due to the overlarge tonnage of ships during the mooring process,which could cause floating bollards to be stuck or slow movement,and lead to potential safety risks.The detection method for the operating status of floating bollards based on the laser distance measuring technology and Outlier detection was proposed,which used the laser distance measuring technology to get positions of bollards,and then K-means clustering algorithm and IQR algorithm were combined to determine if there were problems such as being stuck by detecting the outliers in positions.The position acquisition hardware circuit was constructed based on serial port server,and the host software with functions like position acquisition and status analysis of bollards was developed based on Qt platform,therefore the automatic detection for the operating status of floating bollards was realized.Onsite experiments show the system operates stably,and the real-time collecting and analysis on the position data of floating bollards was achieved.The results is shown on the interface,which provides an applicable method for the real-time detection of the operating status of floating bollards.
