无人机在船舶水尺计重中电磁干扰研究

应用无人机技术,可实现海关鉴定人员在船上操控无人机完成观测船船六面吃水,但船舶上的通导设备和岸上装卸设备会对无人机操控信号和图传信号造成干扰。本文通过测试实船在卸货前后甲板上的电磁信号,分析船舶甲板上各区域的信号干扰强度,确定船舶甲板上适于操控无人机的位置,以保证海关鉴定人员安全、高效和便捷地使用无人机观测船舶水尺读数。

In the process of draft survey,customs officers need to observe the six-spot draught of bulk carrier to calculate the weight of the cargo after loaded or unloaded.The traditional observation method is that the surveyors take a boat to carry out the draft mark reading.By applying the new drone technology,the surveyors or the officers can control the drone on ship's deck to complete the observation of the six spot of the ship's draft mark.The navigation equipment onboard and the on-shore handling(both loading or discharging)equipment will cause many interference to the drone signal transmission.Therefore,the position of the drone on the deck of the specific bulk carrier requires relatively small interference.This paper gives and analyzes the signal interference intensity of each area on the vessel up deck by testing and analyzing the electromagnetic signals before and after unloading.Through analysis the position of the ship's deck suitable for maneuvering the drone is given so as to ensure safe,efficient and convenient.
