Description
Technical field
The invention belongs to automatic measurement field, and in particular to a kind of mistake for lockage ship profile on automatic measurement canal
Lock shipboard automation measuring system and ship profile measuring method.
Background technology
At present, on canal by the lockage of ship lock using gross ton as charge foundation, each ship lock adjusts station to ship provided with remote
Oceangoing ship is scheduled management and tonnage core is carried, and is to take manual site to measure ship and carried with reference to navigation book to appraising and deciding for ship gross ton
The mode that the gross ton of confession is combined.Driven by interests, ship type is lack of standardization, many books of a ship, the small book of big ship, false book, serious overload etc.
Violation phenomenon happens occasionally, and causes channel safe hidden danger, lockage inefficiency.Ship length and width, moldeed depth, seawater amount pass through artificial
The method measured, manually the method for measuring waste substantial amounts of human and material resources, the lockage time of boat people, be not easy to ship information
Collect management, and these ship lock carry the current task of hundreds of ships daily, and workload is big, task is heavy, hand
Continuous complexity, existing charge and management system can not substantially meet the requirement of development of the situation.
It is varied for the charging mode of lockage ship both at home and abroad, but it is required for understanding the profile chi of lockage ship
It is very little.At present, the inspection for lockage dimension of ship and loading capacity relies primarily on the archives of ship, the measurement of important appearance and size
Rely on artificial mode.Restricted by ship archives reliability and efficiency of manual measurement, the accuracy of lockage charge and section
The property learned is in urgent need to be improved.Therefore, in order to solve ship problem present in the ratification method of ship gross ton in lockage, one is studied
Efficient, automatic, quick lockage shipboard automation measuring system is planted, the efficiency of service for improving ship lock has become one important
Business.
The content of the invention
Present invention solves the technical problem that being to provide a kind of lockage shipboard automation measuring system and ship profile measurement side
Method, it is therefore an objective to composite measurement is carried out to ship formal parameter by the system integration, the automation collection of ship shape data is realized,
The actual sizes such as length and width, moldeed depth, the draft of Ship ', automatically generate the ship such as ship threedimensional model and gross ton, displacement
Oceangoing ship key parameter, administrative department collects lockage and provides foundation during for ship lockage, improves the work of Shiplock management department
Make efficiency and the lockage efficiency of ship.
The technical scheme is that：
In order to solve the above-mentioned technical problem, the invention provides a kind of lockage shipboard automation measuring system, the system
Including：Data process subsystem and coupled transversal planar survey subsystem waterborne, under water transversal planar survey subsystem, ship
Oceangoing ship linear measure longimetry subsystem and level measuring subsystem, the transversal planar survey subsystem waterborne include：

Time during position；
PLC, for gathering the data of optoelectronic switch and level measuring subsystem and being sent to data processing subsystem
System.
The system is to carry out profile scanning to ship paragraph by paragraph for the measurement of ship formal parameter, and ship is constituted by scan data
The profile of oceangoing ship section, measures the length or speed of ship, according to the profile of the section of ship and the length of ship in vessel motion
Degree synthesizes the profile of whole ship.For the profile scanning of upperworks, using the metering system of laser scanning, for
The profile scanning of underwater portion, the metering system scanned using sonar, sonar sensor to the bottom by launching a certain frequency
Acoustic signals, when sound wave reaches water-bed or density more than water-bed interface in water with the 1500m/s velocity of sound, the energy of acoustic wave segment
Amount, which is reflected back through echo-signal, to be measured.After ship is by specified Measure section region, the system passes through water
Upper first laser scanner, second laser scanner, sonar sensor are measured crossed ship and each broken to ship section survey
The profile in face, is measured in combination with optoelectronic switch to speed of the ship in metres per second, calculates the length of ship.When ship normally travel
When, by ship displacement of the length of ship as corresponding to the time interval of profile scanning is divided into each Scanning Section, so as to be formed
The 3 d measurement data of ship.Data process subsystem carries out data processing, analysis to the data that measure and stored, according to being surveyed
The three-dimensional data obtained sets up ship model, calculates length, width, freeboard, draft, the gross ton of ship and load-carrying
Ton, and measurement data is automatically saved.Answered when accurately calculating lockage according to measurement data combination networking charging system at remote tune station
The lock fee collected is used, and automatically generates relevant statistics.
In ship measured zone, the system energy automatic measurement passes through the outer shape of ship, automatically extract ship length,
Width, freeboard, draft, define whether shipping draft meets waterway classification requirement, and the freeboard of ship is
It is no to be stored in database in legal scope, and by measurement data.Ship lock at different levels can be accurate by the data in called data storehouse
