Description
Technical field
The present invention relates to fields of measurement, more particularly to a kind of ship borne type drauht automatic checkout system.
Background technology
Along with the continuous increase of the river Provincial Shipping Volumes such as the Changjiang river, boats and ships development, in maximization development trend, is absorbed water also more and more deeper.Calculation of Ship Grounding's accident happens occasionally, not only break up navigation channel serious threat shipping safety, also have impact on shipping efficiency. the reason causing Calculation of Ship Grounding's is many-sided, wherein super drinking water most serious of all, and namely the drinking water of boats and ships actual load exceedes the channel maintenance depth of water that navigation channel department announces.
It is many-sided for causing the reason that boats and ships surpass drinking water, and existing odjective cause also has subjective reason.Objectively the 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 to be also often adjusted according to the change of water level.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 and even privately distort water line and escape the inspection of law enforcement agency, put country's 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.
Administer it is critical only that of drauht problem drauht is detected, traditional approach arranges water line exactly on boats and ships, by estimating the draft amount judging boats and ships, the simple dependence manpower of mode of this drinking water detection and would be likely to occur drauht line scale and obscure, even suffering artificial amendment, drauht detection is inaccurate.This mode needs boats and ships to pull in shore to check on the other hand, affects the normal/cruise of boats and ships, greatly reduces work efficiency.Can take the technological means being correlated with that drauht is detected under can being effectively improved the premise that work efficiency does not affect boats and ships normal/cruise again, realize drauht is carried out monitor in real time 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 is with Hull sinkage, the reading of pressure transducer changes, and has reacted the size of hydraulic pressure, can be obtained the change of the depth of water by scientific algorithm. and the method precision is not high, and pressure transducer is arranged on outside hull, navigation process easily causes damage.
Two, electric water gauge
Electric water gauge have employed data collecting instrument and digital display instrument combines.Its operation principle is the potential difference utilizing the conductive characteristic of water to measure two electrodes, thus measuring waterlevel data. the method precision is not high, and the method needs to be arranged on outside hull by electric water gauge, electric water gauge work under bad environment, it is easy to cause sensor degradation.
Three, laser water level measurement method
The method, mainly by laser range finder, owing to laser has smoothed-spline surface, good directionality, utilizes laser measurement, and with hull bottle limit for datum level, detection main ship deck, to the distance of the water surface, by converting, calculates ship draught.Laser range finder is necessarily mounted on ship, it is impossible to realize disembarkation and drauht is detected.
Four, based on the water gauge marker recognition of 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 very severe such as greasy weather, stormy waves etc. or water line are damaged all affecting the identification of image, impact identifies that the inefficacy of algorithm even occurs in longitude.
Five, salt cavern gas storage
Sonar to measure is the effective ways that object under water is monitored.In channel maintenance works, it is mainly used in bathymetric surveying, underwater obstacle, shipwreck detection and Underwater Engineering facility measure.Main external form yardstick for the underwater portion of current the Changjiang river boats and ships, in conjunction with existing measurement technological means and equipment, the application of metering computer software and exploitation, Yangtze River waterway the composite factor such as natural conditions feature, currently mainly have three kinds based on sonar drauht dynamic testing method: water-bed fixing face upward the method for sweeping, water-bed half floating facing upward is fixed side in the method for sweeping, water and swept method.But little with systematic research for utilizing sonar technique that drauht carries out detection method both at home and abroad at present, and sonar equipment is of a great variety, does not still detect now sonar equipment and the method for drauht, 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 the boats and ships that scanning sonar passes over to water surface emission detection beam scanning from sonar form the image outline of inner bottom hull, thus judging shipping draft.But adopting advantage in this way is that certainty of measurement is high., this mode is applied in Yangtze River Water ships that transport, and drinking water detection there is problems of easily being covered by the mud in river, or covered by rubbish in pasture and water, water, 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 be erected on the flying fish in water by scanning sonar that removable water-bed semi-floating faces upward Scanning Detction method, flying fish keeps posture steady in water, sonar transducer is emission detection wave beam vertically upward, when boats and ships pass over from flying fish, scanning sonar forms the sonar image of inner bottom hull, is analyzed by water-bed cable transmission sonar processing center ashore.Adopting the advantage that removable water-bed semi-floating faces upward Scanning Detction method is that arranging of test point is convenient, flexible, it is simple to safeguard.But easily being covered by rubbish in pasture and water, water in measurement process, reliability is not high.
3) water is fixed side scanning method
Fixing side scanning method in water to be by side-scan sonar emission array and accept array and be separately mounted on two bridge piers, emission array and receiving array are one-to-one relationships.When having boats and ships through out-of-date, the signal near water surface part Firing Sonar is blocked by boats and ships and cannot arrive receiving array, may determine that shipping draft according to the degree of depth of the sonar array that can receive signal.The advantage of this mode does not affect Navigation in Navigable when being and install, and fairway depth is not specially required, and maintaining is convenient.Shortcoming is as follows: 1. this device is necessarily mounted on the fixing building on bridge pier or both sides, navigation channel, is difficult to find that in shallow draft waterway upstream suitable bridge is for installing；2. the bridge span on current the Changjiang river is general very big, is typically between 100-800m, and under so big bridge span, sonar array alignment exists very big difficulty；3. when carrying out drauht detection, it is easy to the impact of the bubble that propeller produces when being subject in water float such as pasture and water, plastic bag and ship's navigation.
