Measuring type unmanned ship and measuring method thereof

Abstract

A measuring type unmanned ship comprises the following structures including a ship body, a GNSS mainframe, a depthometer and a wireless data transmission module, wherein the ship body forms a hardware bearing platform for the unmanned ship; a cabin with a sealed space is arranged in the ship body; the GNSS mainframe is used for detecting the current position of the unmanned ship; the depthometer is used for detecting the water depth in the current position of the unmanned ship; the wireless data transmission module is connected with a control device and used for transmitting the current position information and an equipment working state and receiving a control instruction. A measuring method of the measuring type unmanned ship comprises the following steps that the unmanned ship automatically measures a preset water area according to an instruction signal obtained by the control device and automatically matches the measured water depth data and corresponding position coordinates of measuring points; the water depth information and the position information are transmitted and backed up through the wireless data transmission module and a memory; after the measuring range is finished, multi-point water depth information of the water area can be obtained; and then the information is summarized to obtain water depth status and underwater topography status of the water area.

Description

technical field [0001] The invention relates to the technical field of hydrographic surveying and ocean monitoring, in particular to a surveying unmanned boat and a surveying method that automatically samples, surveys, maps or detects water depth and seabed topography in a set water area. Background technique [0002] At present, the projects and content of marine surveying and mapping are increasing, which puts forward higher and higher requirements for the research and development and application of surveying and mapping methods and technologies. In offshore bathymetric surveys, manual surveying and mapping is usually carried out by boat, line by line, and area by line. It is generally divided into two parts: one is the deep sea area far away from the shore (the water depth exceeds 15m); the other is the near-shore shallow sea area (the water depth is 0-15m). [0003] When working in deep sea areas, large ships (with a draft above 3.5m) are usually used to set up measurin...

AI Technical Summary

Problems solved by technology

However, the difficulty of operation in shallow water areas is much greater than that in deep water areas, and there are the following problems in actual operation: first, it is difficult to set up measuring equipment on small boats; second, small boats generally can only operate when the tide is high, and cannot achieve all-weather operations; third, The environment of nearshore waters is usually very complicated: shoals, hidden reefs, etc. will bring great safety hazards to the survey work; Fourth, the working environment of field investigators on small boats is extremely difficult and safety cannot be guaranteed
