Description
Technical Field
The invention relates to a monitoring and alarming system for protecting offshore underwater heritage, in particular to a monitoring and alarming system for protecting offshore underwater ancient sunken ship cultural heritage.
Background
The ancient sunken ship is one of the most site types for carrying out underwater archaeological investigation at present and is most easily stolen and broken by people. At present, the safety of underwater cultural heritage, especially heritage is optimistic, and is faced to be illegally stolen and fished, and damaged by fishery production, sea-related capital construction and other reasons. Underwater sites are severely damaged by human factors, and the greatest threat comes from salvaging for commercial purposes. The ancient sunken ship remains, because of its large cargo carrying capacity, better preservation, high value, become the main object of lawless crazy robber. The illegal molecule steals underwater cultural relics generally adopt a small high-speed ship with extremely high maneuvering performance, and after approaching to the site of a sunken ship, a simple pipe is used for launching the device to steal and dig, and the target on the water surface is very small. Moreover, the theft and drag actions are generally selected to be carried out suddenly at night, so that the theft and drag actions are not easy to find and have extremely high concealment. Once the patrol ship is found to be close, the patrol ship is rapidly started to roll away, or the stolen salvaged cultural relics are thrown into the water at a low speed, so that law enforcement personnel can hardly obtain evidence even after capturing. At present, the market lacks a mature physical defense device which can be directly used for protecting and monitoring underwater heritage, so that an underwater monitoring and alarming system for protecting heritage of ancient sunken ships is needed.
Disclosure of Invention
The invention provides a monitoring and alarming system for cultural heritage protection of a offshore underwater ancient sunken ship, which aims to solve the technical problems in the prior art.
The invention adopts the technical proposal for solving the technical problems in the prior art that: an offshore underwater remains protection monitoring and alarm system comprises an underwater monitoring part and a land alarm part; the underwater monitoring part comprises a plurality of underwater detection sonars and an underwater sound signal receiver; the underwater detection sonar are uniformly distributed around the underwater remains and fixed on the water bottom for installation, and the detection distance covers the whole underwater remains; the underwater sound signal receiver is arranged at the front edge of the land wharf, receives the underwater sound signal sent by the underwater detection sonar, and converts the sound signal into an electric signal; the land alarm part is arranged on land and comprises a singlechip, a loudspeaker and a network transmission module, wherein the singlechip is used for receiving an electric signal sent by the underwater detection sonar, triggering the loudspeaker to shout and alarm, sending alarm information to the network transmission module and notifying cultural relics and law enforcement departments.
The underwater detection sonar adopts a passive sonar.
The underwater sound signal receiver adopts a passive sonar, and the underwater installation depth exceeds 1 meter.
The underwater detection sonar comprises a spherical sonar, a supporting rod and an anchoring pressing block, wherein the spherical sonar is supported by the supporting rod, the supporting rod is fixed on the anchoring pressing block, the anchoring pressing block is of a reinforced concrete structure, and a battery compartment is arranged inside the anchoring pressing block.
The invention has the advantages and positive effects that: the 4 underwater detection sonars are distributed in a certain net shape, can generally cover the whole ancient sunken ship, and passively receive noise signals in the water body around the ancient sunken ship in a passive mode. The underwater frog steals the cultural relics, the underwater frog steals the cultural relics and can generate radiation noise signals, mainly comprises breathing sound, a breather pressure reducing valve, breathing bubble cracking sound and the like, wherein a breathing regulator used is a main sound source for generating the radiation sound signals, the sound signals show periodic characteristics along with the breathing frequency of the frog, after the underwater detection sonar collects the periodic noise signals, a 37.5KHz underwater sound signal is automatically emitted, and after receiving the signals, an underwater sound signal receiver at the code head side automatically triggers an alarm, so that underwater remains such as ancient sunken vessels can be effectively protected underwater.

Detailed Description
For a further understanding of the invention, its features and advantages, reference is now made to the following examples, which are illustrated in the accompanying drawings in which:
referring to fig. 1, a system for monitoring and alarming off-shore underwater remains, which is usually referred to as cultural remains of an ancient sunken ship, wherein the ship is about 20m in length and about 5m in width, is submerged in the water, and a part of the ship body is positioned below a mud surface or is covered by mud entirely, and the position of the ancient sunken ship is not more than one kilometer away from the land on the shore. The monitoring and warning system comprises an underwater monitoring section and a land warning section 301.
The underwater monitoring device comprises 4 underwater detection sonars 101, 102, 103 and 104 and 1 underwater sound signal receiver 201 positioned at the front edge of a land wharf. The underwater detection sonar is a passive sonar which passively receives sound signals in a water body. The effective detection distance of the underwater detection sonar is 10 meters, 4 underwater detection sonars are uniformly distributed on the periphery of the sunken ship, 101 is located in the middle of the left side of the sunken ship, 2 meters away from the sunken ship, 102 is located in the front of the ship head, 1 meter away from the sunken ship, 103 is located in the middle of the starboard of the sunken ship, 2 meters away from the sunken ship, 104 is located at the rear side of the tail of the sunken ship, and 1 meter away from the sunken ship. The underwater detection sonar detects the sound field around the sunken ship in real time and constructs a time domain model, and after the periodic noise signals radiated by frogman are automatically extracted and identified, the underwater sound signals with the frequency of 37.5KHz are automatically emitted. Each sonar is an independent working mode.
As shown in fig. 2, the underwater detection sonar 101, 102, 103 or 104 includes three parts of a spherical sonar 11, a support rod 12 and an anchoring press block 13. Spherical sonar diameter 20 cm, bracing piece height 1 meter, anchor briquetting length 1 meter, wide 1 meter, high 0.8 meter, reinforced concrete structure, the battery compartment is located inside the anchor briquetting.
The underwater sound signal receiver 201 is located at the front edge of the land wharf, has a water depth exceeding 1 meter, can receive the underwater sound signal with the frequency of 37.5KHz, has an effective distance of 3000m, and can convert the underwater sound signal into an electric signal. The underwater sound signal receiver 201 is a passive sonar and is used for receiving sound signals with specific frequency of 37.5KHz in water. The underwater acoustic signal receiver 201 is powered by land 220V ac power.
The land alarm portion 301 is disposed near the land dock, includes a single-chip microcomputer, a loudspeaker, and a network transmission module, and is connected to the underwater acoustic signal receiver through a cable. The singlechip receives the electric signal sent by the underwater sound signal receiver, triggers the megaphone to give an alarm, and sends alarm information to the network transmission module to inform cultural relics and law enforcement departments.
Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and many forms may be made by those having ordinary skill in the art without departing from the spirit of the present invention and the scope of the appended claims, which are within the scope of the present invention.
