Summary of the invention
Purpose of the present invention:The present invention has overcome above-mentioned deficiency of the prior art, the drauht and the river level measuring system of a kind of special miniature wave amplitude and water gauge are provided, only need adopt miniature, simple video frequency graphic monitoring system equipment, can show in real time and comprise on-the-spot real-video image true, objective, just, high precision measuring data, thereby make the video frequency graphic monitoring system equipment that adopted and accessory equipment micro-miniaturisation thereof, simplification, the investment economized.
Main technical schemes of the present invention is:In order to solve the problems of the technologies described above, the present invention realizes by following technology: the measuring tube that is installed in drauht measuring position or river level measuring position, measuring tube top has opening to communicate with atmosphere, the bottom has in the fine channel water supply turnover pipe, also comprise the information-based scale graduation of millimeter value of series with the measuring tube combination, give basic still water and the place's photography and vedio recording of the information-based scale graduation intersection of millimeter value of series in the measuring tube, perhaps give and measuring tube in basic still water the parallel plane of certain distance and the photography and vedio recording device of the information-based scale graduation intersection of millimeter value of series place's photography and vedio recording are arranged, be the target of photography and vedio recording promptly with above-mentioned intersection place, photography and vedio recording device gained video image is transferred to control monitor unit through transmission of video images part 4, and control monitor unit receives the video image that is sent by the photography and vedio recording device, show or also can store, unofficial biography and management; The information-based scale graduation 2 of described millimeter value of series is to be 1 millimeter (1mm) in each root scale division value, or each root scale division value is 2 millimeters (2mm), or each root scale division value is 3 millimeters (3mm) ..., or each root scale division value is that other all the mark from scale marking is counted zero point of identical several millimeters scale marking is accurate to millimeter or is accurate to than the millimeter scale number of subsection more.
Described photography and vedio recording device is that the control mechanism by minisize photography picture pick-up device and carrier thereof and the action of manipulation minisize photography picture pick-up device constitutes.
In addition, the present invention has also used with the technology of the floating object in the measuring tube as minisize photography picture pick-up device carrier; And when the minisize photography picture pick-up device adopts wireless device, using miniature solar power system, or minitype wind power power generating system, or miniature solar wind power system gives technology such as radio micro photography and vedio recording power devices.
Described basic still water is the very small water surface of fluctuating range.Basic still water in the described measuring tube, promptly when measuring tube is installed in the measuring position and measures, water progresses in the measuring tube, the water surface rises gradually in the measuring tube, the water surface rises to the state of equilibrium that to a certain degree then can present upper and lower minor fluctuations, and the water surface of this state of equilibrium promptly is called basic still water in the measuring tube.
The interior basic still water of described and measuring tube has a parallel plane of certain distance, promptly on the floating object in measuring tube, is higher or lower than the basic still water certain distance and plane that be parallel to basic still water in the measuring tube when measurement is set.
Alleged " special miniature " of the present invention is different from the general microimage technology miniature.
Described special miniature wave amplitude dwindles the wave amplitude of nature wave exactly by certain technical measures.The present invention adopts measuring tube to show the technology of wave longitudinal plane of symmetry, and the wave amplitude of wave is narrowed down to very small degree.
Described special miniature water gauge is to be called for short, and its full name is special miniature boats and ships water gauge sign or special miniature river gauge.Use a kind of minimum division value, water gauge numeral, all very small a kind of special chi of water gauge numeral spacing exactly, i.e. the information-based scale graduation of millimeter value of series among the present invention.When utilization the present invention measures drauht or river level, replacement or additional minimum division value, water gauge numeral, water gauge numeral spacing three existing legal boats and ships water gauge sign or river gauge all bigger than normal.
The effect of each main portion is as follows:Using top has opening to communicate with atmosphere, and the measuring tube in the fine channel water supply turnover pipe is arranged at the bottom, and its effect is: eliminate wave to absorbing water the influence of measuring, improve survey precision; The 2nd, the wave amplitude of wave is made " special miniature " handle.Theoretical and experimental results show that measuring tube can accurately show the center-line-average face of local waters random sea face around the measured place, quite accurately show the measured place longitudinal plane of symmetry of local waters random sea wave on every side in other words, with the gauge reference target face of this face as drauht or river level, compared with the longitudinal plane of symmetry on the irregular corrugated of artificial subjective estimation as the gauge reference target face, science, more reasonable more is so can increase substantially objectivity, fairness and the accuracy rate of result of a measurement.Measuring tube can accurately show the center-line-average face on irregular corrugated, is equivalent to the wave amplitude of wave is modulated to very small degree, and the fluctuation range of the intersection of corrugated and object is also very small a little.The effect of using the information-based scale graduation of millimeter value of series is: existing legal boats and ships water gauge sign or river gauge carried out " special miniature " technical finesse.The combined action of measuring tube and millimeter stages of digital information scale combinations is: dwindle significantly and include the area of high precision measuring data at the video recording picture of interior measure field outdoor scene.Thereby be that the video frequency graphic monitoring system equipment that adopted and accessory equipment micro-miniaturisation thereof, simplification, investment economized have been created condition.
Here what deserves to be explained is: isolated measuring tube technology, or the information-based scale graduation technology of isolated millimeter stages of digital all can not produce these two effects that technical combinations produced and effects.
And be minisize photography picture pick-up device carrier with the floating object in the measuring tube, realized automatic follow shot shooting target, make the current and the floating object of turnover measuring tube become control mechanism.Adopt miniature solar power system etc. to give radio micro photography and vedio recording power devices, do not need artificial power supply.Make accessory equipment further micro-miniaturisation, simplification, investment economized, and, realize drauht measurement or automation of river level measuring system or semi-automation in simple mode.
The present invention is not only applicable to measurements such as drauht, river level, also is applicable to liquid level, the liquid volume of cargo hold, ballast tank etc., the measurement of liquid weight.
About measuring tube:The fine channel that the present invention is alleged, be meant the sectional area of fine channel by current, compare enough small with sectional area in the measuring tube, small in making flow enough small by fine channel, small in making the wave amplitude that enters into the measuring tube water flow inside enough small compared with the wave amplitude of local waters wave around the measuring tube, small requirement to the coincidence measurement precision.Be 30cm to the maximum as local waters, measuring tube outside wave wave amplitude, require to make the maximum amplitude of the basic still water that is presented in the measuring tube during measurement below 3mm.Specifically implementation step is: at first select the suitably measuring tube of the interior sectional area of size, obtain the interior sectional area value of fine channel again with the method for theoretical calculating or experiment.
Structure and shape about measuring tube
:Measuring tube is generally flat, also the curve-like that can match with the outer side of a ship side of certain particular boat privileged site.This moment, the information-based scale graduation of millimeter stages of digital of combination was similarly curve-like with it.Measuring tube can be made of a joint, also can be made of two joints or more piece; The length of measuring tube can be fixed, and also can regulate.
About the information-based scale graduation of millimeter value of series:Supplemental instruction be: the numerical value of described scale number generally adopt the millimeter (mm) as measure unit.And the metering method of this numerical value has two kinds: a kind of is universal, and the numerical value of its scale number is straight-line distance; Another is a tailored version, and the numerical value of its scale number is the straight-line distance on multiview drawing;
So the present invention will adopt the information-based scale graduation of millimeter value of series, be that digital spacing is all too big because existing legal " boats and ships water gauge sign " reaches minimum division value, water gauge numeral and the water gauge of " river gauge ", the picture that causes showing the measure field real-video image must be enough greatly, causes based on video frequency graphic monitoring commercial measurement device relative complex, huge and invest high key factor.The application of the information-based scale graduation of millimeter value of series can make the minimum division value of inland navigation craft water gauge sign miniature to 1mm by 20mm; Water gauge numeral height is miniature to 1 to 2mm by 100mm, and the digital spacing of water gauge is miniature to several mm by 100mm.Thereby it is miniature to not adopting more than one percent when of the present invention at the video image area of interior measure field outdoor scene to include high precision measuring data.
In case of necessity can also the scale marking of the information-based scale graduation of millimeter value of series other increase mark out of Memory mark as: measuring position, name of vessel, river title, measure water level place etc.The out of Memory mark can be arranged with symbolic representations such as numeral or letters.Make distant place video image accepter grasp more first-hand information in real time like this.
The level gauging that is used for cargo hold, ballast tank etc.The additional information tag of the information-based scale graduation of millimeter stages of digital at this moment can be the volume or weight of liquid.Promptly other except mark degree of depth indicating value at scale marking, mark pairing liquid weight of this degree of depth indicating value or volume numerical value simultaneously.
The accurate numerical information scale graduation of millimeter level can also be made the noctilucence chi, so that measure night.
The combination of the alleged measuring tube of the present invention and the information-based scale graduation of millimeter value of series generally is the information-based scale graduation of millimeter value of series to be fixed on directly along the measuring tube short transverse both constitute an integral body on the measuring tube.Also can on measuring tube, directly make the information-based scale graduation of millimeter value of series.The information-based scale graduation of millimeter value of series can also be fixed on boats and ships water gauge sign or above the river gauge or its nearside, former boats and ships water gauge sign or river gauge are as the rough usefulness of observing, and the information-based scale graduation of millimeter value of series is used for exact measurement.Even the information-based scale graduation independent utility of millimeter value of series can be replaced drauht sign or river gauge.But should make information-based scale graduation of millimeter value of series and the closely connected combination of measuring tube when measuring, both constitute an integral body.Generally the information-based scale graduation of millimeter value of series is similarly flat shape when measuring tube is flat shape, and the information-based scale graduation of millimeter value of series is similarly curve shape when measuring tube is curve shape.
The alleged minisize photography picture pick-up device of the present invention be meant have photography, shooting or the micromodule equipment of recording function(comprise miniature wired camera as microcam, the micro radio pick up camera, micronet pick up camera etc.), minisize pick-up head (comprises miniature wired camera, the micro radio camera, the micronet camera, the micro radio camera of 3G standard, the simulation camera, digital camera is first-class), miniature digital camera, the mobile phone of configuration camera especially can carry out the mobile phone (as supporting the mobile phone of 3G) of video calling, and other includes i.e. i.e. the miniature imaging instrument of " metal oxide semi-conductor " such as the sight glass etc. of (the electric charge lotus root is closed element) or CMOS of photo-sensitive cell CCD.
Transporting part about video imageCan adopt wire transmission, or employing transmission over radio, or part adopts wire transmission and part to adopt the mixed transport mode of transmission over radio, or at minisize photography picture pick-up device internal memory (as miniature DVR), after shooting is finished, be connected with the USB of computer and can show the video image of being produced, its similar is in commercially available " shooting recording USB flash disk pen ".
About control monitor unitSpecifically how from known technology, to select relevant control monitor unit equipment, will consider that then metering system is full automaticity, S. A. or ccasual random measurement, and whether need unofficial biography, measure factor decisions such as cost.Generally at first selected photography and vedio recording device 3 and transmission of video images part are determined control monitor unit again with matching.As select the simulation camera for use and only require and receive in real time and show, then control monitor unit can be with minitelevision or small-sized Liquid Crystal Display (LCD); Then can select for use video frequency collection card to add miniature notebook PC if also require storage, management; If require the unofficial biography then can be again with the built-in wireless network card of miniature notebook PC; As select wired camera for use, then control monitor unit can directly be used miniature notebook PC; As select wireless camera for use, then control monitor unit can constitute with wireless image receptor and the miniature notebook PC of bonded assembly thereof.
Is carrier technique about the minisize photography picture pick-up device with the floating object in the measuring tube
Its technical scheme is: will have the carrier of the floating object of certain buoyancy as the minisize photography picture pick-up device in the measuring tube, rising along with the water surface in the measuring tube, floating debris cognition is being followed water surface rising in the pipe automatically, the minisize photography picture pick-up device is being followed floating object automatically and is being risen, to rise to static substantially then floating object also static substantially along with the water surface in the measuring tube, and the minisize photography picture pick-up device also can be static substantially thereupon.Realize that the minisize photography picture pick-up device is automatically with combining the photography and vedio recording target, this target is a basic still water and the information-based scale graduation intersection of a millimeter value of series place in the measuring tube, perhaps this target be with this measuring tube in basic still water a parallel plane and the information-based scale graduation intersection of a millimeter value of series place of certain distance are arranged.At this moment control mechanism is exactly natural flows and the floating object in the fine channel turnover measuring tube.
The minisize photography picture pick-up device is a carrier technique with the floating object in the measuring tube, and concrete application generally is divided into two kinds of forms: promptly single hose minisize photography picture pick-up device is the measurement mechanism of carrier with the floating object in the measuring tube; With double hose minisize photography picture pick-up device be the measurement mechanism of carrier with the floating object in the measuring tube.
In order to make the camera lens of minisize photography picture pick-up device at the complex water areas environment measurement, aim at the photography and vedio recording target all the time, simple straight-line guidance mechanism should be set between the floating object of measuring tube and Qi Nei in case of necessity, make the floating object can only be along the rectilinear direction lifting.The form of straight-line guidance mechanism is a lot, as Cylindroid: a cylindroid vertically is installed in measuring tube, cooresponding on the floating object within it an elliptical aperture that is complementary is set; As the semicircle pillar: one or two semicolumns are set on the inwall of measuring tube, cooresponding on the floating object within it the half slot that one or two is complementary are set; The bicylindrical formula: appropriate location vertically is provided with two cylinders in measuring tube, cooresponding on the floating object within it two circular holes that are complementary is set; The shape guide type: be shaped as oval or prismatic (the simplest is triangular prism) as measuring tube 1, floating object maximum area place within it has and the similar and smaller shape of measuring tube shape.For the resistance of reducing friction as far as possible, also can the spin of right quantity be set at the floating object maximum area place similar and smaller to the measuring tube shape, slide to replace with rolling.
Is the wireless measurement device of carrier about solar power or wind energy power supply with floating object in the measuring tube
When adopting wireless minisize photography picture pick-up device, then adopt miniature solar power system, or the minitype wind power power generating system, or miniature solar wind power system gives radio micro photography and vedio recording power devices, do not need to change battery or charge the battery.Above-mentioned power generating system can place the inside or the outside of measuring tube.
About including the installation requirement of the measuring tube and the front end measurement mechanism of the information-based scale combinations body of millimeter value of series
The front end measurement mechanism (following can abbreviate the front end measurement mechanism as) that the present invention is alleged includes measuring tube and the information-based scale combinations body of millimeter value of series specifically is meant: a measuring tube and the information-based scale combinations body of millimeter value of series, or single hose minisize photography picture pick-up device is the measurement mechanism of carrier with the floating object in the measuring tube, or double hose minisize photography picture pick-up device is the measurement mechanism of carrier with the floating object in the measuring tube.When actual measurement, front end measurement mechanism installation requirement: (one) short transverse: preferential employing is identical with boats and ships water gauge sign or river gauge altitude datum, the i.e. information-based scale graduation of millimeter value of series and boats and ships water gauge sign or river gauge, the scale mark horizontal alignment of both equal readings.Also can make the altitude datum of the information-based scale of millimeter value of series and boats and ships water gauge sign or river gauge that certain difference is arranged.(2) length direction: for boats and ships, preferential employing is identical with rib position, boats and ships water gauge sign place or distance is extremely near; But as also have any problem can be different with the existing rib position, water gauge sign place of boats and ships, but increase the conversion step.(3) Width: three kinds of installation forms are arranged.One is an external, promptly is installed on outer side of a ship side of hull or the river gauge carrier or nearside; It two is inserted, promptly is mounted to hull or river gauge carrier the inside, makes its outside and hull side of a ship side or river gauge carrier surperficial concordant or concordant substantially outward; It three is built-in, promptly is installed in hull interior, but should obtains the agreement of administration of ship department.(4) plumb bob vertical direction: except the shaped form conformal installation method shown in accompanying drawing 9a, 9b, general front end measurement mechanism all should be the plumb bob vertical direction.
Pay special attention to a little: no matter take which kind of installation form, all must make measuring tube top have opening to communicate with atmosphere, the bottom has the fine channel in the turnover measuring tube that supplies water to communicate with the waters of boats and ships outboard.
Concrete various installation forms see following embodiment for details.
Beneficial effect of the present invention against existing technologies:Contrast the drauht survey meter of Chinese utility model patent 02219118.6, the present invention has increased some new technical characterictics, and main has:
1, adopted miniature video frequency image monitoring system technical equipment;
2, adopted boats and ships water gauge sign and river gauge carried out special miniature millimeter stages of digital information scale graduation, and with the measuring tube applied in any combination;
3, with the carrier of the floating object in the measuring tube as the minisize photography picture pick-up device;
4, the bottom at measuring tube bottom fine channel is equipped with water filter;
5, the opening part suitable for reading at measuring tube is provided with ventilative dustproof and waterproof device;
6, miniature solar power system is installed on measuring tube, or the minitype wind power power generating system, or miniature solar wind power system gives radio micro photography and vedio recording power devices.
7, micro photo electric equipment such as light source, power supply and wireless remote controlled receiver etc. are installed on the floating object of measuring tube, also can the double as densimeter;
8, at configuration height standard on the measuring tube or on the connected rod member, rope.
9 and be used for the up-to-date technologys such as conformal installation method that drauht is measured.
No longer need artificial interpretation drinking water data.Again because of video image can amplify, so measuring accuracy is higher.Also available low investment, easy means realizes the automatic measurement of drauht or river level.Improve widely and expanded practicality.
Contrast Chinese utility model patent 200820141846.7 wireless remote control drauht measuring systems, though all be based on the video frequency graphic monitoring systems technology, but the present invention has adopted again: 1 eliminates the wave effect technology, 2 wave wave amplitudes " special miniature " technology, the special microphotography of 3 drauht signs or river gauge, 4 automatic trackings are taken the photograph the photography and vedio recording object technology, and 5 miniature solar power systems etc. are given radio micro photography and vedio recording power devices technology, 6 conformal installation methods etc.So the present invention has significant technological advance compared with Chinese utility model patent 200820141846.7 wireless remote control drauht measuring systems.Its major advantage is as follows:
1 survey precision height.Survey precision is the primary factor of decision measuring instrument or measuring system using value.China's utility model patent 200820141846.7 wireless remote control drauht measuring systems have factor---the wave of significant impact for drauht or river level survey precision, do not make the reply technical finesse.Absorbing water shown on the video image of on-the-spot outdoor scene in the resulting measurement of this measuring system is the original looks of nature wave fully, quick fluctuations along with wave, the intersection of corrugated and boats and ships water gauge sign is also done fast and the fitfull fluctuations, the same center that can only estimate " dynamically intersection " with appearance method, therefore can not obtain unique, objective, just, high-precision result of a measurement, it is uncertain to obtain the same result of a measurement with appearance method, error is big, precision is low, changes with human element.The present invention has used measuring tube to show the measurement point technical measures of the center-line-average face of local waters random sea face on every side, has made effective processing for the influence that wave is measured drauht, thereby has improved survey precision significantly.Through the Changjiang river full scale test, when the wave amplitude of wave was more than 30 centimetre, the amplitude peak that the basic still water institute in the measuring tube fluctuates up and down only had 3 millimeters, is approximately one of percentage of nature wave wave amplitude.3 millimeters wave amplitudes are got 1.5 millimeters of its intermediate values, are that reference plane absorbs water or level measuring must increase substantially survey precision with such face.
Equipment is miniature, simple.Because the shooting target of Chinese utility model patent 200820141846.7 wireless remote control drauht measuring system finders is " drauht lines ".So-called " drauht line " is exactly the intersection of corrugated and boats and ships water gauge sign or rather.Owing to fluctuate in the corrugated, so " intersection " is actually and wave wave amplitude " dynamically intersection " of a size.Simultaneously, because this utility model is not carried out " special miniature " technical finesse to the wave amplitude of wave, minimum division value, water gauge numeral and the water gauge numeral spacing problem all bigger than normal of existing legal boats and ships water gauge sign or river gauge are not taked any technical measures yet, cause its captured comprising " dynamically intersection " with close on " water gauge numeral " must be enough big at the video pictures area of the complete demonstration drinking water of interior energy data, thereby cause employed video frequency graphic monitoring system equipment and the attendant equipment thereof must be huge and complicated.。
Because the photography and vedio recording target of photography and vedio recording device of the present invention is: basic still water and the information-based scale graduation intersection of millimeter value of series place in the measuring tube; Perhaps with measuring tube in basic still water a parallel plane and the information-based scale graduation intersection of a millimeter value of series place of certain distance are arranged.Because the present invention has adopted the information-based chi combination technique of carving of the millimeter stages of digital of measuring tube and special miniature boats and ships water gauge marker technique, the small wave amplitude of the basic still water that presents in the measuring tube has only one of one of tens even percentage of original wave wave amplitude.The corrugated is very small with the fluctuation of millimeter stages of digital chi intersection at information-based quarter in the measuring tube.Therefore, the present invention can complete demonstration comprise the on-the-spot real-video image that is accurate to millimeter take off data, Chinese utility model patent 200820141846.7 wireless remote control drauht measuring systems is only arranged, about one of percentage of similar picture size.Therefore, the used equipment of the present invention micro-miniaturisation, simplification, investment economized relatively.As Chinese utility model patent 200820141846.7 wireless remote control drauht measuring systems, adopt the wireless remote control pick up camera, the present invention then adopts minisize pick-up head to get final product; The former carrier is wireless remote control ship or wireless remote control marine aircraft, and it is the carrier of minisize photography picture pick-up device that the present invention has then adopted with the cursory object in the measuring tube; The former described control setup comprises that the delivery/absorption controller of wireless remote control body and adsorber reaches and the shooting controller of wireless remote control pick up camera, the control mechanism that the present invention then moves as manipulation minisize photography picture pick-up device with the natural flows of turnover measuring tube, floating object, the simple type automatic technology of realization automatic tracking photography and vedio recording target.The present invention compares with Chinese utility model patent 200820141846.7 wireless remote control drauht measuring systems, has miniature, the simple advantage of system equipment.
Cost of investment is low.
Practical.WithChina's utility model patent 200820141846.7 wireless remote control drauht measuring systems are compared, advantage of the present invention is: equipment micro-miniaturisation, simplification, volume is little, in light weight, cost of investment is low, maintenance cost is low, operation is easy to carry, very easily realizes automation or semi-automatic advantage.
Easily be automated measurement.China's utility model patent 200820141846.7 wireless remote control drauht measuring systems, can only be to ship in ballast drinking water and the isolated measurement respectively of each six measurement point down of load draft state, using miniature video frequency graphic monitoring system equipment technology of the present invention, reaching with the cursory object in the measuring tube is the automatic tracking photography and vedio recording object technology of the carrier of miniature video camera equipment, reach applied solar energy or wind energy and give radio micro photography and vedio recording power devices technology, measure with the automatic measurement or the semi-automation of simple and easy pattern realization drauht or river level cheaply easily, thereby greatly improved efficiency of measurement.
The safe navigation that helps boats and ships.Boats and ships for the front end measurement mechanism that includes measuring tube and the information-based scale combinations body of millimeter value of series in the fixed installation, in case find the shown drinking water data exception of certain measurement point in six measurement points, marine accident then takes place probably, and prompting must be checked immediately.Since the accuracy rate height of the drauht data that the present invention is shown, thus take precautions against the highly sensitive of marine accident, if increase then better effects if of panalarm again.
The beneficial effect compared with some prior aries of the present invention is in a word: used measuring system small investment, micro-miniaturisation, simplification, but can from the measure field real-video image that provides in real time, can forever preserve unofficial biography, obtain the result of a measurement of direct, directly perceived, true, objective, just, high-precision drauht or river level with accurate take off data.And, simple to operate, convenient, to carry with easy to maintenance, energy-conserving and environment-protective easily are automated and measure or semi-automatic the measurement, also help the safe navigation of boats and ships
,Has application value.

Specific embodiment explanation:Adopt which kind of video monitoring system, use the analog video monitored control system, or digital video monitor system, or network video monitor and control system, or video monitoring of mobile phone system etc. all to select according to composite factors such as measuring concrete environment, condition, requirement and investment size.Because of video monitoring system is a known technology, in specific embodiment, generally be not described in detail.
The high precision simple type automatic measurement of water levels such as mode 1 river, lake, reservoir
On the water gauge that measurement water levels such as existing river, lake, reservoir are used, according to the identical principle of altitude datum, is the measurement mechanism of minisize photography picture pick-up device carrier with double hose with floating object in the measuring tube 1, be fixed on the water gauge, minisize photography picture pick-up device 6 is selected the micro radio night vision cam for use, make the information-based scale graduation 2 of its alignment lens millimeter value of series, and adopt miniature solar power system, or the minitype wind power power generating system, or miniature solar wind power system gives radio micro photography and vedio recording equipment 6 power supplies.Control monitor unit 5 is to be made of wireless image receptor and bonded assembly microcomputer thereof.The advantage of this method is: automation, the high-precision level measuring of realizing river, lake, reservoir etc. with very low cost of investment.
The low input high-precision automatic level measuring of mode 2 newly-built ship lock
Mounting means adopts inserted, be about to measure the water level water gauge, and the double hose of fixing on it is the measurement mechanism of minisize photography picture pick-up device carrier with floating object in the measuring tube 1, is mounted to the lock wall the inside of newly-built ship lock together, and the outside is with the good material sealing of diaphaneity.Its sealing surface is concordant substantially with lock wall metope, and is not only attractive in appearance but also do not influence navigation.Measure the rough usefulness of observing of water gauge work that water level is used, double hose is the measurement mechanism of minisize photography picture pick-up device carrier with floating object in the measuring tube 1, measures usefulness as automatic precision.Because of close together, wiring can be adopted the cabled digital camera easily, and should establish a wheel disc has than length adjusting usefulness as cable; After the length adjusting, cable also will be reserved the less nargin of freely stretching, and to adapt to the needs of wired camera trace ascending, descending, control monitor unit directly adopts microcomputer.Also can adopt wireless video monitoring system, method is then with reference to last example.
The automation of mode 3 drauhts or semi-automatic the measurement
Drauht during Weight Check by Draft is measured more numerous, the drinking water at six water gauge sign places in the time of should measuring clean ship, and the drinking water at six water gauge sign places when measuring heavy duty again just can calculate the weight of its lade.For the boats and ships that carry out Weight Check by Draft for a long time, when shipbuilding or during shiprepair, preferably with the front end measurement mechanism that includes measuring tube 1 and information-based scale graduation 2 fabricate blocks of millimeter value of series of the present invention, be fixedly mounted on six measurement points of boats and ships, so that save each time of measuring a large amount of Assembly ﹠Disassembly when absorbing water, simultaneously because fixed installation is easy to accomplish accurate positioning, survey precision height.Can measure the needs of boats and ships load draft again according to measuring light ship draught, make the front end measurement mechanism that includes measuring tube 1 and information-based scale graduation 2 fabricate blocks of millimeter value of series have enough length, require fixed installation respectively according to aforementioned identical method with boats and ships water gauge sign altitude datum.Specifically in the following several ways:
(1), the flat type conformal is installed method as shown in Figure 8
In the accompanying drawing 8, part 21 is corrugated (wavy waters surface), part 20 is outer side of a ship sides of hull, part 19 is the front end measurement mechanisms that include measuring tube 1 and information-based scale graduation 2 fabricate blocks of millimeter value of series, and preferentially adopting single hose or double hose is the measurement mechanism of minisize photography picture pick-up device carrier with floating object in the measuring tube.Mainly be applicable to, when boats and ships water gauge sign place is or part is outside the flat type vertical with the boats and ships base plane during side of a ship side.Include the front end measurement mechanism of measuring tube 1 and information-based scale graduation 2 fabricate blocks of millimeter value of series, be installed in place, drauht measuring position with flat shape.。
Its advantage be constitute front end measurement mechanism 19 measuring tube 1 and with the information-based scale graduation 2 of millimeter value of series of its combination, all be flat shape, make simple and convenient, and can be general.When if the boats and ships turn of the bilge is circular arc, hull will be left in front end measurement mechanism lower end, if unfavorable to safe navigation, then front end measurement mechanism 19 can be designed to hoist type, it is fixing promptly at ordinary times front end measurement mechanism 19 upwards to be promoted the back, is lowered into required position with 19 again during measurement.Perhaps front end measurement mechanism 19 is designed to concertina type, can stretches as required, can contract.
Minisize photography picture pick-up device 6 can use wireless or wired, and method is with reference to front embodiment.
(2), the shaped form conformal is installed method.As accompanying drawing 9a is that shaped form external conformal is installed the method scheme drawing.9b is that the inserted conformal of shaped form is installed the method scheme drawing.
The advantage of this method is that the outer side of a ship side of front end measurement mechanism and hull is identical closely connected, helps safe navigation.Shortcoming is that information-based scale graduation 2 making of measuring tube 1 and millimeter value of series are more tired, and can only be special-purpose, can not be general.Pay special attention to: when the end measurement mechanism is a curve shape, though or be flat shape but when favouring the hull base plane, the numerical value metering method is in the then described scale number: the chi face of the information-based scale graduation 2 of millimeter value of series, on the orthographic drawing on this boats and ships hull center line face from zero point scale marking count to the straight-line distance of the scale marking that is marked.If when the information-based scale graduation 2 of millimeter value of series is expanded into linearity, then every adjacent two scale division values are that 1 millimeter distance between (1mm) scale marking is not quite similar, or equal 1 millimeter (1mm), or big 1 millimeter (1mm).Briefly, what at this moment adopt is the true length of projector distance rather than Zhan Zhihou, neither be as the ordinary steel ruler simple straight-line distance.
Above fixed setting method largest benefit is to put things right once and for all, and saves each the measurement a large amount of set-up times.
It is the measurement mechanism of carrier with the floating object in the measuring tube 1 that the front end measurement mechanism preferentially adopts the minisize photography picture pick-up device.As have any problem and can only adopt measuring tube 1 and information-based scale graduation 2 fabricate blocks of millimeter value of series, but then the people stands on the deck, hand-held rod member, and the rod member lower end is fixed with the minisize photography picture pick-up device of anti-drainage facility and gathers the measure field real-video image.The people of this moment and rod member just become the control mechanism of handling the action of minisize photography picture pick-up device.Also can a simple rack be installed at the measuring tube appropriate location, make the minisize photography picture pick-up device of anti-drainage facility can do the upper and lower mobile of certain distance, sagging by deadweight, the people stands on the deck with cable traction or adopts known wireless remote control technology facility, the minisize photography picture pick-up device is moved to the appropriate location gather the measure field real-video image.At this moment people, rope or wireless remote control technology facility etc. just become the control mechanism of handling the action of minisize photography picture pick-up device.
For fixedly mounting the boats and ships of going up the front end measurement mechanism, in case find the shown drinking water data exception of certain measurement point in six measurement points, marine accident then takes place probably, prompting must be checked immediately.Since the accuracy rate height of the drauht data that the present invention is shown, thus the highly sensitive of marine accident forecast, if increase then better effects if of panalarm again.

Can also be without witness marker piece 22, and use the witness marker line, the witness marker line can be mutually perpendicular two lines, be respectively the position baseline of height and length direction, as long as the module on the front end measurement mechanism 19 is installed according to the witness marker line, then front end measurement mechanism 19 will inevitably satisfy positioning requirements.
When adopting above-mentioned mount scheme, when adopting wired minisize pick-up head or microcam again, it is more different to it is also noted that measurement light ship draught and the required length of cable of measurement load draft have, and can adopt the automatic or manual adjusting of wheel disc; This external measurement light ship draught or itself also will consider to make cable that less flexible allowance be arranged when measuring load draft, the needs when adapting to wired minisize pick-up head or camera lifting.Can be equipped with 1 cover video distributor, respectively 6 road video parts that light ship draught is measured and load draft is measured be distributed to DVR DVR video acquisition storage equipment, carry out this locality demonstration, monitoring, storage by local network on the ship.A part 2 road videos are passed to the wireless video server by image splitter, connect maritime satellite BGAN equipment again, and monitoring and control centre and the port relevant with Weight Check by Draft passed to are on the bank supervised department, imported and exported inspection and quarantine department, the owner of cargo, client etc.
