Underwater search and rescue robot

Underwater search and rescue robot

The types and configurations of underwater search and rescue robots vary depending on their purpose and application environment. The detector is usually composed of a detector and a detector carrier.

Underwater detector：It is usually a sensor or camera used to detect underwater organisms or other objects. Underwater detectors can detect underwater targets through methods such as sound waves, lasers, and electromagnetic waves, obtaining information about the shape, color, size, and motion of the targets. Due to the complexity of underwater environments, we generally choose acoustic probes to detect underwater targets. Acoustic probes mainly include forward-looking multi wave sonar and side scan sonar.

Forward-looking multi wave sonar　　

Forward Looking Multi Beam Sonar (FLMBS) is a technology that utilizes sound waves for detection and imaging. It can emit multiple sound beams and receive reflected signals, thereby generating high resolution threed-imensional images in underwater environments.

　　   FLMBS is mainly used for the detection and imaging of underwater objects, such as underwater relics, submarine pipelines, sunken ships, underwater terrain, etc. Its working principle is to utilize the propagation characteristics of sound waves in water, and determine the position, shape, and size of objects based on the reflected signals of sound waves.

　　FLMBS has high detection accuracy and resolution, and can detect underwater details and small-sized objects. At the same time, it can also perform real-time imaging and navigation in underwater environments, which has important application value for underwater detection and operations.

　　Side scan sonar

　　Side scan sonar(Side Scan Sonar)It is a technology that uses sound waves for underwater detection. It generates a two-dimensional image of an underwater target by emitting sound waves and then receiving signals reflected back by the underwater target.

　　The working principle of side scan sonar is to place the sound wave transmitter and receiver on both sides of an underwater detection device (such as underwater robots, ships, etc.), radiate the sound wave beam to both sides, cover a larger underwater area, and use the propagation characteristics of sound waves in water to detect targets and generate two-dimensional images. Therefore, it can generate detailed underwater target images, including the shape, size, position, and other information of the object.

　　Side scan sonar is mainly used for underwater detection and imaging, such as surveying underwater terrain, detecting sunken ship remains, and inspecting underwater pipelines. Side scan sonar has wide application value in underwater surveying and operations, as it can quickly and efficiently detect large areas of underwater targets and provide detailed target information.

　　In practical applications, the selection of detector carriers varies due to differences in underwater detection directions and application scenarios. The detection carrier is usually carried by unmanned ships or underwater robots.

Side scan sonar is usually the preferred product for search and rescue teams, and can be quickly searched when mounted on unmanned ships or speedboats。 Moreover, side scan sonar has a relatively low cost of ownership. The side scanner is usually operated by dragging it to the back of the ship or installing it on a pole on the side of the ship。 Side scan sonar provides sonar images below it, including the left and right sides of the location where the side scan sonar is located.If Side scan sonar is stationary and cannot establish an image of the seabed because it can only image on both sides of its location. Therefore, it needs to move forward to provide users with an image of the seabed. It can cover a large area of search in a relatively short period of time. If GPS information is integrated, it can also conveniently check the location of interest and obtain the latitude and longitude coordinates of the location in the later stage.

　　Underwater robot+multi wave front sight sound

The installation of multi wave front sight sonar is more flexible, unlike side scan sonar which must be installed on one side. Multi wave front view sonar can obtain clearer images, but multi wave sonar imaging can only be at 60 ° or 120 ° angles, depending on the type of multi wave. Compared to side scan sonar, the area scanned per unit time by multi wave speed sonar is greatly reduced, and searching for the same area takes longer than side scan. The cost of multi wave imaging sonar is several times higher than that of side scan sonar.
