The invention discloses a face-up scanning type ship actual load tonnage calculation method and system, and the method comprises the steps: obtaining the distance value Hn between each sensor and the ship bottom and the distance value C between a detection door and the water surface, calculating the depth value of each position of the section of a ship at the moment according to the obtained information, and caching the depth values in an array M, carrying out numerical value section selection and correction processing on the array M to obtain an actual draught value Wn of each section of the ship under the condition that the ship body is not inclined, carrying out curve fitting on the actual draught value Wn, and carrying out station section division on the fitted curve according to the distance between the stem and the sternpost of the ship to obtain the ship type drainage volume; obtaining the ship displacement according to the ship type drainage volume, the ship hull coefficient and the water area density; and obtaining the ship load according to the ship displacement and the ship empty load weight. According to the invention, the measurement of the actual load ton of the off-ship ship is realized, the man-machine interaction is enhanced, the working efficiency of the system is improved, and the violation phenomena of ship overload and false report of ship weight are solved.
本发明公开了一种仰扫式船舶实载吨位计算方法及系统,其中方法包括:获取每个传感器器距离船底的间距值Hn和检测门距水面的间距值C,根据获取的信息计算出船舶此时剖面每个位置的深度值,并将深度值缓存到数组M中,对数组M进行数值段选取和矫正处理,得到该船舶在船体没有倾斜情况下各个剖面的实际吃水值Wn,对实际吃水值Wn进行曲线拟合,将拟合后的曲线对照船舶艏柱和艉柱间长进行站段划分获取船舶型排水体积;根据船舶型排水体积、船壳系数以及水域密度获得船舶排水量;根据船舶排水量和船舶空载重量获得船舶载重。本发明实现了离船船舶实载吨的测量,增强了人机交互并提高了系统工作效率,解决船舶超载和虚报船重的违规现象。
