Description
Technical field
The present invention relates to a kind of installation method of equipment, a kind of installation method on the spot of Ocean Surveying equipment is specifically referred to.
Background technology
Present ocean scientific research, using etc. be required for widely understanding Sea World, so, the mistake of this understanding
Journey, is the heuristic process to ocean, the process detected by modern science and technology instrument, equipment.
With the fast development of marine cause, people are for marine resources, the detection of marine environment and research constantly deep
Enter, wherein depth measurement instrument plays more and more important role in mankind's Activities of Ocean, in the numerous areas related to ocean
Also it is widely used, has been increasingly becoming the basis of marine exploration and exploitation.
Marine exploration instrument species is enriched, of all kinds, and wherein oceanographic observation instrument kind is most, by its mode of operation again
The formula of jettisoning, self-turning-back, suspension type, pull-type etc. can be divided into.Its Sensor section is put into marine, sight when expendable instrument is used
The data of survey are delivered on ship by wire or radio wave, sensor use after not recycling.Sunk to during self-turning-back Instrument observation
It is marine, ballast is laid down after completing measurement or sampling task, return to sea by means of natural buoyancy.Suspension type instrument is using the strand on ship
Car suspension rod is marine from ship side side feeding, is observed in ship anchorage or in the case of drifting about.From ship when pull-type instrument works
Tail be put into it is marine, towing ship it is laggard walking boat observation.
Because there is oceanographic instrumentation instrument to connect complexity, installation operation step is more, and the bodily form is huge, the huge spy of weight
Point, along with operation on the sea stormy waves is larger, ship jolts, these external factors both increase staff installing instruments and
Danger coefficient in measurement process.Therefore it provides a set of ripe, simple, safe and reliable instrumentation installation procedure is to continue with
The problem of solution.
The conventional equipment and instrument of the ocean scientific investigations such as sub-bottom profiler, single beam echosounding instrument, GPS instrument.Multibeam echosounder
It is a kind of efficient, high-precision underwater topography, sweeping survey equipment based on marine acoustics principle, it is real compared with single beam echosounding instrument
Leap of the water-depth measurement by " point-line " to " line-face " is showed, has been particularly well-suited to large area and sweeps extra large operation.Because multi-beam is surveyed
Deep instrument is poor to high, the marine sea situation of basic matrix installation accuracy requirement, measurement expense is expensive and surveying vessel model is different, to being widely used in
The topside of multibeam echosounder basic matrix hang installation accuracy, installation effectiveness, convenience and the versatility of erecting device and all carry
Requirement higher is gone out.Generally easy basic matrix hangs erecting device and is not applied for regular Multi-beam Echosounding System work to high-precision
The requirement of degree, installation effectiveness high and suitable dress property high, and the overwhelming majority is only applicable to a certain model surveying vessel, particularly because marine survey
Amount bad environments, if hanging, erecting device design is unreasonable will to waste a large amount of manpowers, and are particularly easy to cause installation effectiveness and peace
Dress lack accuracy.
In addition, for a long time, water-depth measurement is always manually to beat deep, and depth measurement instrument is mainly Sounding Rod and sounding bob.Survey
Deep bar is general to be processed by materials such as wood, bamboo, fiberglass, the graduation on bar.Need the Sounding Rod there can be various length according to different
Metric lattice, when the depth of water exceedes certain depth, it is impossible to use depth measurement cast when being measured using Sounding Rod.Measuring point localization method
Mainly use method of intersection by sextant.
The certainty of measurement of traditional depth detecting method is influenceed very big by objective factor, particularly in the condition that stormy waves and flow velocity are larger
Under, easily cause reading and forbidden and Sounding Rod, the out of plumb reading problems of sounding bob lining rope；When the depth of water and larger flow velocity, receive
Water currents, Sounding Rod and sounding bob lining rope are easily bent, and the depth of water for measuring can be caused bigger than normal.Additionally, traditional depth detecting method is also
Potentially include other errors that human factor is caused.
In order to realize the digitlization of water-depth measurement, can be using the single-frequency digital sounding instrument or double frequency digital sounding of in the market
Instrument, digital sounding instrument is connected by navigation software waterborne with GPS, can in real time, accurately, automatically record the depth of water and phase of any measuring point
Answer coordinate, it is to avoid the mistake that traditional depth detecting method is likely to occur in links such as artificial operation, reading, record, calculating, carry significantly
The high precision of hydrographic, operating efficiency and digitized degree.
Spread speed of the acoustic signals of single beam echosounding instrument in water is general between 1400~1550m/s, and the velocity of sound is
Change with the difference of the density of water, salinity and temperature.Because density of sea water is big, salinity is high, the velocity of sound in seawater is more than light
Water.Generally, sounding instrument manufacturer a echo depth sounder is both provided in the user documents (shipped with equipment) that dispatches from the factory in different temperatures and
The velocity of sound table of comparisons under water of salinity, so as to real-time calibration；But meanwhile, also emphasize that the data only set the ginseng of the depth of water as user
Examine, user also needs to calibrate sounding instrument with other method.Therefore, actually measurement in, it is impossible to only by " measure water temperature and
The method of salinity, the corresponding velocity of sound that calculation is looked into input one in table " obtains an accurate depth of water, to be typically also used in combination
The depth measurement numerical value of Sounding Rod calibrates sounding instrument.
General common practice is：Ship will be surveyed and be anchored on smaller flow velocity, the shallower waters of 2~3m of the depth of water and river bed, kept
Survey ship stabilization.Starting navigation depth measurement software carries out depth measurement, while manually being beaten using Sounding Rod deep.Then, by two kinds of depth measurements
Result compares, if transfinited, to check, adjust that drinking water, velocity of sound of sounding instrument etc. are set.What this method was present mainly asks
Topic has：One is, because artificial depth measurement is influenceed larger by environment, human factor, there is certain error, and correcting sounding instrument with it is difficult to
Ensure certainty of measurement.Two be artificial depth measurement with fathometer sounding position it cannot be guaranteed that identical, and river bed typically changes greatly, it is difficult to
Level terrain is found, therefore brings certain error.Therefore, development is needed badly a kind of suitable for various waters, not by water depth ratio, wind
The factor influence such as wave, artificial, it is ensured that put the accurate method of identical, numerical value than location, to ensure that sounding instrument sets correct, depth measurement
Accurately.
The content of the invention
The present invention is in view of the shortcomings of the prior art, it is proposed that a kind of side that may insure reliable measuring data, convenient use
Method, this method is from the beginning to be installed in place equipment, to realize the complete, accurate etc. of data during follow-up use.
The present invention is achieved by following technical proposals：
A kind of installation method on the spot of Ocean Surveying equipment, including to sub-bottom profiler, single beam echosounding instrument, GPS instrument
