耙吸式挖泥船日志系统数据后处理程序开发

Development of data post-processing program for log system of trailing suction dredger

对“浚洋1”挖泥船日志系统基础架构进行解析。基于Python设计开发日志系统的数据后处理程序,建立耙吸船运行参数数据库,实现数据的可视化显示和交互功能,提出基于时序和时刻的耙吸船工作状态判定算法。以斯里兰卡科伦坡港口城发展项目(2017—2018年)为例,结合施工日报统计数据对程序算法进行测试,结果表明该算法具有较好的鲁棒性。

The basic architecture of“Junyang 1”logging system is analyzed.The data post-processing program of the logging system is designed and developed based on Python.The operation parameter database of the suction harrow is established,and the visual display and interactive function of the data are realized.The algorithm based on time sequence and time is put forward to judge the working state of the suction harrowing vessel.Taking the Colombo Port City Development Project in Sri Lanka(2017—2018)as an example,the algorithm of the program was tested with statistical data of daily construction.The results show that the algorithm has good robustness.
