Description
Technical Field
The invention belongs to the technical field of submarine vacuum pipeline traffic and underwater sonar, and particularly relates to a submarine vacuum pipeline sonar system and a working method.
Background
The development and application of electromagnetic waves are one of the most important scientific and technological achievements in recent human life, and greatly influence the aspects of human social economy, life and scientific technology, even military activities. In the first half of the 20 th century, the typical application fields of electromagnetic waves, such as radio, radar, etc., have been developed; in the latter half of the 20 th century, television, wireless communication (such as mobile phones) and satellite communication based on electromagnetic wave technology are popularized and applied on a large scale.
In the 21 st century, the satellite communication technology GPS based on electromagnetic waves, Beidou navigation and the like are further developed, the earth near space becomes a world surrounded by thousands of artificial satellites, dead angles of observation, detection and communication of any region on the earth surface are avoided, and the precision and the resolution reach the mm level.
On the ground, communication machine stations are distributed all over the ground, and powerful support is provided for mobile phone application through a radio wave relay propagation mode. In the past 20 years, wireless communication has gone through the 2G, 3G, and 4G era, and is moving to the 5G era.
The most basic function and technical feature of satellite communication and terrestrial communication base stations is to transmit and receive radio waves (electromagnetic waves).
However, one of the unsatisfactory points of the electromagnetic wave service to human beings is that the electromagnetic wave is attenuated in water so fast that the propagation distance is only several tens of meters, so that the electromagnetic wave cannot be used for underwater communication. Therefore, human beings can not achieve full coverage, no dead angle and full time domain for detection and communication of oceans, especially the seabed world, which occupy more than 70% of the sphere surface.
Unlike electromagnetic waves, acoustic waves attenuate very little in water, and Sonar (Sonar) as an underwater communication technology is produced accordingly. Nowadays, sonar has been widely applied to fields such as submarine, torpedo, underwater vehicle, underwater location tracking, seabed measurement, ocean detection, these characteristics of using are: singleton and tentative.
The single-point property means that the existing sonar equipment is scattered under the sea, and the effective coverage range meeting the delay requirement is very limited, such as submarine sonar, torpedo sonar, spy sonar, marine survey sonar and the like. Although terrestrial communication base stations are also single-point scatterers, the communication base stations can perform the tasks of transmitting/receiving radio waves with a large number of user equipment (such as mobile phones) in a medium of atmospheric space (or vacuum) relatively independently. Underwater sonars can directly transmit sound waves to communicate with each other, and also can directly communicate with nearby sea-surface ships, but cannot directly communicate with sea-surface ships far away, and even cannot directly communicate with remote land equipment (only through one medium). The existing underwater sonar needs to depend on a buoy (equivalent to a sea surface antenna) to carry out remote communication, such as seabed detection sonar and spyware sonar. Since the towed buoys, such as spy sonar buoys and unmanned undersea vehicle buoys, are sometimes discovered and cut by fishermen and even captured along with spy sonar and undersea vehicles. Even for civilian purposes, the global marine world throughout the buoy is still unthinkable and undesirable, with obvious disadvantages, unlike ground based communication stations.
In addition, navigation of the torpedo and the underwater vehicle needs to depend on sonar equipped by the underwater submarine or nearby sea surface naval vessels, and the communication distance is very limited.
The temporary characteristic means that all existing sonar equipment is applied in a mobile mode or exists at a certain position temporarily, such as sonars equipped by submarines, torpedoes, underwater submergence vehicles, ocean exploration and the like. Although a spy sonar can exist at a fixed position for a long time, the spy sonar still belongs to temporary equipment compared with a ground communication base station.
Then, it is obviously not feasible to consider an array-type, permanent sonar network that is installed completely on the sea floor without depending on buoys, because of the limited battery life. It is possible to power these array, permanent sonars via submarine cables, but it is obviously uneconomical to build submarine cables specifically for submarine sonars. If the electromagnetic wave communication is not enough by means of a certain seabed facility with practical application value, the seabed facility is promoted mutually and developed gradually, and a global seabed sonar communication network is built, so that the seabed sonar communication network becomes a technology development path which is worth exploring.
The submarine vacuum pipeline is an about-to-be-implemented trans-sea and transoceanic transportation mode. The basic form is that a pipe pier is built on the seabed, then a vacuum pipeline section is erected on the pipe pier according to the required precision by an underwater construction method, and all pipelines are fixedly connected by an underwater sealing connection method. The submarine environment has special superiority to the vacuum pipeline, and the sea water can provide even buoyancy for the vacuum pipeline cooling, provide the constant temperature environment, still can provide even buoyancy for the pipeline, offsets the effect of pipeline self gravity, reduces structural strength requirement, reduces engineering cost. In the future, the seabed vacuum pipelines are distributed over the seabed of all oceans in the world, and the seabed sonar communication network is built by the seabed vacuum pipelines, so that the seabed sonar communication network is expected to have good economic effect and development prospect.
