Unmanned ship is a fully automatic surface robot that can navigate on the water according to the preset task without remote control, with the help of accurate satellite positioning and self sensing, which is abbreviated as USV. Nowadays, many countries have begun to develop unmanned ships. Some shipping giants even optimistically predict that the mature “ghost ship” technology will rewrite the face of global ocean transportation in only a few decades. Others in the industry predict that the scale of the global unmanned ship market may reach about US $10 billion (about RMB 61.8 billion) in 2019.
Unmanned ship technology is not only a new breakthrough in the field of water quality detection, but also a hot black technology. Water quality detection unmanned ship is a multi-functional water transportation and carrying platform, which integrates advanced robot control technology and automatic navigation technology, and is equipped with sensors and navigation equipment such as high-precision GPS, electronic compass, water quality sensor and 360 degree pan tilt camera, which can realize the functions of high-precision satellite positioning, autonomous cruise and full-automatic operation.
At this stage, it is cumbersome to monitor the environmental quality of surface water such as rivers and lakes mainly through manual sampling or setting fixed automatic monitors, which can not realize long-term continuous monitoring and timely updating of data. Nowadays, the unmanned ship monitoring system can effectively make up for the limitations of manual sampling and automatic monitoring points in regional distribution. It can measure wherever it goes. Sampling and analysis are carried out simultaneously, which fully saves the time required for monitoring.
When in use, the route is designed in advance, press a key, and the unmanned ship will cruise according to the figure. It is very convenient to come back after the detection is completed. Most of these unmanned ships are powered by electricity. At present, this kind of unmanned ship is widely used in environmental protection cruise and emergency monitoring in various waters, adding new wings of science and technology to water quality monitoring.
Advanced technical means such as satellite remote sensing, UAV aerial photography, unmanned ship monitoring and intelligent robot detection are used to comprehensively investigate industrial wastewater outlets, domestic wastewater outlets and all types of outlets directly and indirectly discharged. Among them, the unmanned ship can collect the water quality monitoring data and transmit it to the data server center through 4G / 5G communication, and the transmission distance is no longer limited by any distance.
When some unmanned ships work, first use ship borne sensors such as water quality sensors to set the sailing time of the route on the water, which can automatically return and return the monitored water quality data, underwater foreign matter, flow rate and other data, so as to lock in the pollution source.
In addition, the concealed pipe detection unmanned ship can also detect the concealed pipe on both banks of the river through the sonar scanning technology, and feed back the measured and scanned sound wave to the computer base station system in real time and intuitively. The on-site investigation personnel can detect the suspected points according to the image presented by the sound wave, combined with the later analysis, judge whether there is a concealed pipe, and save the location information, It is possible to preliminarily identify whether there are concealed pipes in the water area.
