水尺计重是国内外煤炭运输船舶载货量测量中的主要方法,水尺计重数据的准确性为大宗散货交易中商品的结算、纠纷处理、计算运费等的依据。目前水尺计重行业存在由于采用人工观测、人工计算的形式开展散货船重量鉴定所导致的误差大、人工干扰性强,从而易引起导致贸易纠纷,因而急需建立1套智能化水尺计重系统以排除人为干扰及快速实现重量鉴定。以在黄骅港针对煤炭运输船舶开展的智能化水尺计重系统业务为例,基于现场应用情况,从煤炭船舶六面水尺的观测、水尺计重设备、水尺计重数据的采集与计算等方面分析,发现智能化水尺识别系统现阶段对水尺标志的清晰度、水尺智能计重设备集成度、水尺计重数据的采集与计算在避免受人为因素干扰等方面需求进行改进,建议从水尺系统的软件升级、水尺设备的硬件开发、水尺计重大数据系统的建立3个方面进行提升与优化。对智能水尺识别系统软件进行升级后,结合引入机器视觉等先进图像识别技术并加入深度学习的图像处理技术,可实现多环境下对水尺标志的准确识别。高集成度智能化一体化设备可对传感器、数据采集和处理、电源等模块进行多功能集成设计,利用高密度多层电路板优化各模块空间并使用轻量、坚固和高强度的材料,减少检验人员的工序及多工序带来的误差。建立完整的智能水尺计重大数据系统能够实现对数据采集、传输、存储、分析等功能的程序简单化、透明化、高效化,同时对全流程可视化、数据安全性和隐私、信息管理和维护以及业务培训等方面提供有利的保障和支持。

Draft survey is the main method in the measurement of the cargo capacity of coal transport ships at homeand abroad, and the accuracy of draft survey data is the basis for the settlement, dispute resolution, and calculationof freight in bulk cargo transactions. At present, there are large errors and strong manual interference caused by theuse of manual observation and manual calculation in the draft survey industry, which is easy to cause trade disputes,so it is urgent to establish a set of intelligent draft survey system to eliminate human interference and quickly realizeweight identification. Taking the intelligent draft survey system business for coal transport ships in Huanghua Port asan example, based on the field application, from the observation of the six⁃sided draft survey of coal ships, the draftsurvey equipment, the collection and calculation of draft survey data, etc., it is found that the intelligent draft sur⁃vey recognition system needs to improve the clarity of the draft survey mark, the integration of the draft survey intelli⁃gent equipment, and the collection and calculation of the draft survey data to avoid interference by human factors.From three aspects of software upgrade of draft system, hardware development of draft equipment and establishment ofa major data system for draft, the improvement and optimization have been done. After the software of the intelli⁃gent draft survey recognition system is upgraded, combined with the introduction of advanced image recognition tech⁃nologies such as machine vision and the addition of deep learning image processing technology, the accurate recogni⁃tion of draft gauge signs in multiple environments can be realized. The highly integrated intelligent integrated equip⁃ment can carry out multi⁃functional integrated design of sensors, data acquisition and processing, power supply andother modules. Using high⁃density multi⁃layer circuit boards to optimize the space of each module was done, as wellas the lightweight, strong and high⁃strength materials, the process of inspectors and the errors caused by multipleprocesses was reduced. The establishment of a complete intelligent draft survey major data system can realize the sim⁃plification, transparency and efficiency of data collection, transmission, storage, analysis and other functions, andprovide favorable guarantee and support for the whole process visualization, data security and privacy, informa⁃tion management and maintenance, and business training.
