渔船倾斜试验现场控制系统设计

Design of field control system for tilt test of fishery vessel

为减少小型渔船倾斜试验时船上多余的载重导致试验误差,采用渔船倾斜试验现场控制系统使摆锤数据的读取实现了自动化、智能化,精简原来必须在船上采集试验数据的人员数量。现场控制系统的硬件采用内含加速度传感器的摆锤系统进行搭建,软件采用基于C#.NET framework的开发环境结合Access数据库的方式进行研发。介绍了该系统中,船型数据库与摆锤数据库等关键数据库的搭建及系统控制界面的实现方法,并与不采用该现场控制系统而采用2组重力式摆锤的常规倾斜试验进行了比较。结果显示:采用该系统可以实现自动化记录摆锤摆幅,初步计算渔船倾斜角度并导出后续倾斜试验计算所需的数据文件等功能,最终船上试验人员可减少至0人,有效减少试验误差,提高倾斜试验精度。本研究成果可以为渔船倾斜试验提供参考。

In order to reduce the test errors caused by the extra load on board during the tilt test of small fishing boats,a field control system for the tilt test of fishing boats was used to automate and intelligentize the reading of the pendulum data and to reduce the personnel who had to collect the test data on board.The hardware of the field control system is built by a pendulum system with acceleration sensor,and the software is developed by combining the development environment of C#.NET framework with the Access database.The construction of key databases such as ship-type database and pendulum database and the realization of system control interface are introduced.The system compared with the conventional tilt test which is construced with 2 sets of gravity pendulum without the field control system.The experiment results show that the system can be used to automate the recording of pendulum amplitude,to calculate the angles of tilt and to derive the data files necessary for the calculation of subsequent tilt tests,and ultimately reduce the number of testers on board to zero,effectively reducing test errors and improving tilt test accuracy.The research results can be used as a reference for the tilt test of fishing vessels.
