Description
Technical field
The invention belongs to automatic fields of measurement, being specifically related to a kind of lockage shipboard automation measuring system for automatically measuring lockage boats and ships profile on canal and boats and ships profile measuring method.
Background technology
At present, lockage canal being passed through ship lock take gross ton as charge foundation, each ship lock is provided with far away adjusts station to carry out management and running to boats and ships and tonnage core carries, and is the mode taking manual site to measure boats and ships and combine with reference to the gross ton that navigation book provides to appraising and deciding of boats and ships gross ton.Order about by interests, ship type is lack of standardization, the many books of a ship, the large little book of ship, false book, the violation phenomenon such as serious overload happen occasionally, cause channel safe hidden danger, lockage inefficiency.Boats and ships length and width, moldeed depth, the seawater amount method by manually measuring, manually the method for measuring wastes a large amount of human and material resources, the lockage time of boat people, be not easy to gather management to ship information, and these ship lock carry the current task of hundreds of ship every day, workload is large, task is heavy, formality is complicated, and existing charge and management system obviously can not meet the requirement of development of the situation.
Varied for the charging mode of lockage boats and ships both at home and abroad, but all need the physical dimension understanding lockage boats and ships.At present, the inspection for lockage dimension of ship and dead weight capacity mainly relies on the archives of boats and ships, and the measurement of important physical dimension will rely on artificial mode.Be subject to the restriction of boats and ships archives reliability and efficiency of manual measurement, accuracy and the science of lockage charge are all in urgent need to be improved.Therefore, in order to solve boats and ships boats and ships gross ton when lockage ratification method in Problems existing, research one efficiently, automatically, lockage shipboard automation measuring system fast, the efficiency of service improving ship lock has become a vital task.
Summary of the invention
The technical matters that the present invention solves is to provide a kind of lockage shipboard automation measuring system and boats and ships profile measuring method, object carries out composite measurement by the system integration to boats and ships formal parameter, realize the automation collection of boats and ships shape data, the physical size such as length and width, moldeed depth, draft of Ship ', automatic generation boats and ships three-dimensional model and the boats and ships such as gross ton, water discharge key parameter, there is provided foundation for administrative authority during ship lockage collects lockage, improve the work efficiency of Shiplock management department and the lockage efficiency of boats and ships.
Technical scheme of the present invention is:
In order to solve the problems of the technologies described above, the invention provides a kind of lockage shipboard automation measuring system, described system comprises: data process subsystem and coupled xsect measurement subsystem waterborne, under water xsect measurement subsystem, boat length measurement subsystem and level measuring subsystem, and described xsect measurement subsystem waterborne comprises:
First laser scanner, the second laser scanner, be arranged on two sides, river course respectively, for scanning upperworks section, and shape data waterborne for the boats and ships scanned sent to data process subsystem;
The described measurement subsystem of xsect under water adopts the metering system of sonar surface sweeping, comprising:
Two groups of sonar sensors, are installed on both sides, river course water-bed, respectively for transmitting and receiving sonar signal;
Sonar controller, for controlling the transmitting and receiving of sonar sensor, and by the boats and ships collected under water shape data be sent to data process subsystem;
Described boat length measurement subsystem comprises:
Optoelectronic switch, is installed on the lock wall of both sides, river course, time during for detecting boats and ships arrival and leaving optoelectronic switch position, place;
PLC, for gathering the data of optoelectronic switch and level measuring subsystem and being sent to data process subsystem.
This system is carry out profile scanning to boats and ships piecemeal for the measurement of boats and ships formal parameter, the profile of boats and ships section is made up of scan-data, in vessel motion, measure length or the speed of boats and ships, synthesize the profile of whole boats and ships according to the profile of the section of boats and ships and the length of boats and ships.For the profile scanning of upperworks, adopt the metering system of laser scanning, for the profile scanning of underwater portion, adopt the metering system of sonar scanning, sonar sensor is by launching the acoustic signals of a certain frequency to the bottom, sound wave is with when the arrival of the velocity of sound of 1500m/s is water-bed or density is greater than water-bed interface in water, and the energy of acoustic wave segment is reflected back through echoed signal and can measures.When boats and ships are by behind the Measure section region of specifying, this system by the first laser scanner waterborne, the second laser scanner, sonar sensor to boats and ships section survey, measure the profile of each section of crossed boats and ships, in conjunction with optoelectronic switch, speed of the ship in metres per second is measured simultaneously, calculate the length of boats and ships.When boats and ships normally travel, the length of boats and ships is divided into boats and ships displacement corresponding to each Scanning Section by the time interval of profile scanning, thus forms the 3 d measurement data of boats and ships.Data process subsystem carries out data processing, analysis and storage to the data recorded, ship model is set up according to measured three-dimensional data, calculate length, width, freeboard, draft, the gross ton of boats and ships and deadweight capacity, and measurement data is preserved automatically.The lock fee use should collected when tune station far away accurately calculates lockage according to measurement data in conjunction with networking charging system, generates relevant statistics automatically.
