Description
Technical field
The present invention relates to fields of measurement, more particularly to the computational methods of a kind of drauht measured value.
Background technology
Along with the continuous increase of the river Provincial Shipping Volumes such as the Changjiang river, boats and ships develop in maximization development trend, and drinking water is also
More and more deeper.Calculation of Ship Grounding's accident happens occasionally, and not only breaks up navigation channel serious threat shipping safety, also affects
Shipping efficiency.The reason causing Calculation of Ship Grounding's is many, super drinking water, i.e.
The drinking water of boats and ships actual load exceedes the channel maintenance depth of water that navigation channel department announces.
The reason causing boats and ships to surpass drinking water is many, existing odjective cause, also has subjective reason.Objective
The upper upstream and downstream difference navigation channel water level depth is different, and same navigation channel different times allows the extreme draft of navigation boats and ships
Change according to water level is the most often adjusted.Boats and ships are accomplished by landing pier unloading goods for safety navigation,
Extend the time of delivery.Subjective, indivedual shipowners, in order to pursue the maximization of interests, take to lie about, conceal
Drinking water the most privately distort water line escape law enforcement agency inspection, put country shipping overload ban in ignoring,
The safety not only giving relevant navigation boats and ships brings hidden danger, has also had a strong impact on shipping efficiency.
Administering it is critical only that of drauht problem to detect drauht, traditional approach is exactly at boats and ships
On water line is set, judged the draft amount of boats and ships by range estimation, simple the depending on of mode of this drinking water detection
By manpower and there may be drauht line scale and obscure, even suffering artificial amendment, drauht detects
Inaccurate.The most this mode needs boats and ships to pull in shore to check, affects the normal/cruise of boats and ships, greatly
Reduce greatly work efficiency.The premise of boats and ships normal/cruise is not the most affected work efficiency can be effectively improved
Can take down the technological means being correlated with that drauht is detected, it is achieved drauht is supervised in real time
Control and early warning, thus reduce Calculation of Ship Grounding's, the generation of the security incident such as hit a submerged reef, ensure the safety in navigation channel,
Existing drauht detection method mainly has following several:
One, pressure transducer method
The method is the principle design utilizing hydraulic pressure to change along with water depth ratio to be formed.When ship in ballast,
Pressure transducer is arranged on outside hull, after ship loading goods, pressure transducer with Hull sinkage,
The reading of pressure transducer changes, and has reacted the size of hydraulic pressure, i.e. be can get the depth of water by scientific algorithm
Change.The method precision is the highest, and is arranged on by pressure transducer outside hull, holds during navigation
Easily cause damage.
Two, electric water gauge
Electric water gauge have employed data collecting instrument and digital display instrument combines.Its operation principle is to utilize water
Conductive characteristic measure the potential difference of two electrodes, thus measure waterlevel data.The method precision is the highest, and
And the method needs to be arranged on outside hull by electric water gauge, electric water gauge work under bad environment, it is easily caused
Sensor degradation.
Three, laser water level measurement method
The method is mainly by laser range finder, owing to laser has smoothed-spline surface, good directionality,
Utilizing laser measurement, face on the basis of hull bottle limit, the distance of detection main ship deck to the water surface, by changing
Calculate, calculate ship draught.Laser range finder is necessarily mounted on ship, it is impossible to realizes disembarkation and eats boats and ships
Water detects.
Four, water gauge marker recognition based on image procossing
By picture pick-up device, six water lines outside hull are carried out capture, and carry out technology identification, obtain
The drinking water data of boats and ships, and calculate accordingly, obtain the final drinking water situation of boats and ships.When environmental factors ten
Dividing severe such as greasy weather, stormy waves etc. or water line to be damaged all affecting the identification of image, impact identifies
Even there is the inefficacy of algorithm in longitude.
Five, salt cavern gas storage
Sonar to measure is the effective ways being monitored object under water.Mainly should in channel maintenance works
Measure for bathymetric surveying, underwater obstacle, shipwreck detection and Underwater Engineering facility.For the longest
The main external form yardstick of the underwater portion of river boats and ships, in conjunction with existing measurement technological means and equipment, meter
The application of calculation machine software and exploitation, the composite factor such as natural conditions feature of Yangtze River waterway, currently mainly have three
Plant based on sonar drauht dynamic testing method: the method for sweeping of facing upward is fixed at the bottom, water-bed partly floating is faced upward in the method for sweeping, water
Method is swept in fixing side.But the most both at home and abroad for utilizing sonar technique that drauht is carried out detection method and is
The research of system is little, and sonar equipment is of a great variety, the most do not detect the sonar equipment of drauht with
Method, mainly has following several sonar detection device:
1) water-bed fixation
Water-bed fixation is to be arranged in a row multiple scanning sonars to be fixed on the bottom, and scanning sonar is launched to the water surface
The boats and ships that detection beam scanning passes over from sonar, form the image outline of inner bottom hull, thus judge boats and ships
Draft.But adopting advantage in this way is that certainty of measurement is high., this mode is applied to Yangtze River Water
The drinking water detection of upper ships that transport there is problems of easily being covered by the mud in river, or by pasture and water, water
Middle rubbish covers, and be capped, cover after be not easy remove, later maintenance difficulty.
2) removable water-bed semi-floating faces upward Scanning Detction method
It is to be erected on the flying fish in water by scanning sonar that removable water-bed semi-floating faces upward Scanning Detction method, flying fish
Keeping posture steady in water, sonar transducer emission detection wave beam vertically upward, when boats and ships are above flying fish
Through out-of-date, scanning sonar forms the sonar image of inner bottom hull, at water-bed cable transmission sonar ashore
Reason center is analyzed.The advantage using removable water-bed semi-floating to face upward Scanning Detction method is the setting of test point
Convenient, flexible, it is simple to safeguard.But easily being covered by rubbish in pasture and water, water during Ce Lianging, reliability is the highest.
3) water is fixed side scanning method
Fixing side scanning method in water is by side-scan sonar emission array and to accept array and be separately mounted to two bridge piers
On, emission array and receiving array are one-to-one relationships.When having boats and ships through out-of-date, send out near water surface part
Penetrate the signal of sonar to be blocked by boats and ships and cannot arrive receiving array, according to sonar array deep that can receive signal
Degree may determine that shipping draft.The advantage of this mode does not affect Navigation in Navigable, to navigation channel when being and install
The depth of water does not specially require, and maintaining is convenient.Shortcoming is as follows: 1. this device is necessarily mounted at bridge bridge
On the fixing building on pier or both sides, navigation channel, it is difficult to find that in shallow draft waterway upstream suitable bridge is for peace
Dress；2. the bridge span on current the Changjiang river is universal very big, typically between 100-800m, the biggest
Under bridge span, there is the biggest difficulty in sonar array alignment；3. when carrying out drauht detection, easily
The bubble produced by propeller when float in water such as pasture and water, plastic bag and ship's navigation is affected.
