Nowadays, many countries have begun to develop unmanned ships. Some shipping giants even optimistically predict that in just a few decades, the mature "ghost ship" technology will rewrite the face of global ocean transportation. Industry insiders predict that the global unmanned ship market may reach approximately $10 billion (about RMB 61.8 billion) in 2019.
Many people don't know what an unmanned ship is?, Today, the editor is here to explain the main components and knowledge required. Unmanned ships refer to intelligent platforms that rely on onboard sensors to navigate autonomously or semi autonomously on the water surface. As the eyes and ears of unmanned ships, core sensors have always been an important component of unmanned systems. Due to different monitoring requirements, unmanned ship control systems usually carry a large number of sensors and equipment. For example, it can be equipped with high-precision GPS modules, electronic compasses, attitude detectors, salinity and temperature sensors, wind speed and direction sensors, etc., to track water bodies and obtain water quality experimental data.
Specifically, for example, GPS module positioning devices can determine the position and heading of unmanned ships, and track the heading and waypoint; Temperature sensors and salinity sensors can record and store data to measure the surface temperature and salinity of water bodies, and obtain high-precision water quality experimental data.
At present, in China, unmanned ships equipped with different types of sensors can be widely used in marine transportation, marine environment investigation, marine resource exploration, marine archaeology, water search and rescue, intelligence collection, maritime training and testing, reconnaissance and evidence collection, surveillance and patrol, firepower strike, ship escort, anti mine and anti submarine fields. At present, there are dozens or even dozens of sensors on various types of unmanned ships.
Specifically, in the attitude control system of unmanned ships, various sensors need to be configured for complementary detection according to different usage requirements to achieve self state and ocean environment detection. For example, the sensors carried by unmanned ships mainly include various position and attitude detection sensors. Due to the unique characteristics of unmanned ships and their working environment, in addition to the effects of lighting and foggy weather, they also face special challenges in attitude control, such as weak observability of surface targets, severe ship shaking, strong sea clutter, and underwater target detection.
Generally speaking, the attitude sensors carried on unmanned ships are usually equipped with sensor chips such as acceleration sensors, electronic compasses, gyroscopes, etc., which can achieve the function of attitude detection. Specifically, its built-in acceleration sensor can first measure the component of the Earth's gravity in the measurement direction, then convert it into a tilt angle, and finally collect data on the unmanned ship's forward and backward tilt angle, left and right sway angle, mast rotation angle, etc. during the driving process.
Due to the output information of the electronic compass representing the current attitude position. Therefore, in conjunction with other attitude sensors, electronic compasses can be used for attitude and orientation measurements in systems such as unmanned ships that require 360 ° rotation. In addition, due to the integration of three-axis magnetic sensors and three-axis inclination sensors, the high-precision three-dimensional electronic compass module is compact in size and very suitable for systems with high space requirements such as unmanned ships.
Unmanned ships will develop towards systematization, standardization, intelligence, and group collaboration. In recent years, although China's unmanned ships have achieved rapid development in the civilian field, the technology level of unmanned ships in China is relatively low, and there is still a significant gap compared to countries such as the United States, Israel, Norway, and the United Kingdom. In addition to ship type, power, communication technology, and sensor technology, there are significant gaps in attitude control, navigation planning and navigation, control, and clustering.
At present, China is actively developing unmanned ship equipment and receiving related demands and customizations. Overall, in the future, unmanned ship equipment integrated with GPS modules, electronic compasses, inertial navigation, depth sounders, etc. will be increasingly used in various fields such as lake and reservoir water quality, hydrological measurement, underwater terrain and topography measurement, and close range observation.
