Technical field
The present invention relates to tested ship face upward sweep formula drinking water detection technique field, specifically, more particularly to one kind be based on
Formula drauht detection system and method are swept in facing upward for flexible framework support.
Background technique
In recent years, with the raising of navigable technique, China's shipping amount is in the trend of average annual growth, and its cargo transport exists
The developing status of Chinese national economy is higher and higher.Thus it is guaranteed that the unobstructed and safety of China's inland water transport is most important.It is existing
Some, which faces upward to sweep in formula drinking water detection system, is fixed installation, such installation to array of ultrasonic sensors using stainless steel stent
Not only consumptive material is big for mode, heavy, is not easy to installation and maintenance, and its span is also smaller, can only realize within short distance
Navigation ship carry out drinking water measurement, cannot achieve the ship within the big navigation channel to 100 meters or so and carry out drinking water measurement.Separately
Outside, as time go on and the variation of Various Seasonal water velocity, water level, hydraulic pressure, stainless steel stent is generated because of stress bending
Amount of deflection is also increasing, can bring biggish systematic error, influences the measurement accuracy and accuracy of data.
Summary of the invention
According to it is set forth above it is existing face upward sweep formula drinking water detection system there are the problem of, and provide a kind of based on flexible framework
Formula drauht detection system and method are swept in facing upward for support.
To achieve the goals above, the technological means that the present invention uses is as follows:
It is a kind of that formula drauht detection system is swept based on facing upward for flexible framework support, fixed module, ultrasonic sensor battle array
Column module, hydraulic pressure sensor module, floating body compensating module, pivot angle monitoring modular, data processing module；
The fixed module is the spud pile for being mounted on navigation channel two sides beaching position, two beam hawsers across entire navigation channel,
And fixed, spud pile foundation SEA LEVEL VARIATION realization automatic lifting is wrapped on spud pile；
The array of ultrasonic sensors module is multiple ultrasonic sensors, is mounted on hawser at equal intervals,
For measuring the spacing of hawser Yu tested ship；
The hydraulic pressure sensor module is the pressure sensor being mounted on detection door, is become for real-time monitoring water level
Change；
The floating body compensating module is multiple floating bodies, by the way of multiple spot installation, is mounted on hawser at equal intervals
Lower section, for offset reduce hawser bending degree, balance hawser gravity, offset amount of deflection, compensation system error；
The pivot angle monitoring modular is the obliquity sensor for being mounted on hawser center, for monitoring hawser swing
Angle；
In the electrical cabinet of the described data processing module installation on the coast, be used to will to array of ultrasonic sensors module and
It is handled after the data acquisition transmission of hydraulic pressure sensor module measurement, calculates the drinking water value of navigation ship.
Further, pedestal group made of the spud pile is driven as hydraulic device fixed column and concrete casting
At fixed column can carry out automatic lifting adjustment according to the water level value of the hydraulic pressure sensor module monitors.
Further, the spacing of the two beam hawsers is the diameter of ultrasonic sensor, described to install therebetween
Array of ultrasonic sensors module.
Further, the data processing module can with the instruction of pivot angle monitoring modular described in real-time response and with institute
It states fixed module communication and realizes automatic lifting.
The present invention also provides the implementation methods that a kind of facing upward based on flexible framework support sweeps formula drinking water detection system, including
Following steps:
Step 1: building fixed module；
Fixed module is the spud pile for being mounted on navigation channel two sides beaching position, the fixed column that spud pile is driven by hydraulic device
It is formed with pedestal made of concrete casting, fixed column can be risen automatically according to the water level value of hydraulic pressure sensor module monitors
Falling tone is whole, and the cable takeup by two beams across entire navigation channel is in fixed column and fixed, and parallel exceptionally straight as far as possible, guarantees two beam cables
Spacing between rope is the diameter of ultrasonic sensor to install sensor array module therebetween；
Step 2: building array of ultrasonic sensors module；
Step 21: determining the installation site of array of ultrasonic sensors module i.e. hawser in water；If navigation ship is eaten
Water is D, because SEA LEVEL VARIATION value caused by weather, season, water flow factor is D1(0 < D in practice1< 3m), then to guarantee ultrasonic wave
The underwater installation site H > D+D of sensor array module1；
Step 22: ultrasonic sensor of distance installation M towards the water surface on hawser with equidistant d constitutes ultrasound
Wave sensor array module, then n-th of ultrasonic sensor and pull in shore left side spud pile distance SnAre as follows:
Sn=(n-1) d n=1,2 ..., M；
The total length of hawser are as follows:
S=(M-1) d；
Step 23: being referred to according to the two of ultrasonic sensor parameter field angle θ and directive property ω when field angle is smaller
Tropism is bigger, and the performance that ultrasonic sensor plays is better, and array of ultrasonic sensors module is fixed by mounting box level
Between two beam parallel cables；
Step 3: building hydraulic pressure sensor module；
Simultaneously with equidistant d on two beam hawsers1N number of hydraulic pressure sensor is installed, for measure two beam hawsers everywhere with water
The spacing H of plane, examines whether two beam hawsers are parallel to horizontal plane；I-th of hydraulic pressure sensor and the spud pile in left side of pulling in shore
Distance SiAre as follows:
Si=(i-1) d1I=1,2 ..., N

Step 4: building floating body compensating module；
Hawser do not occur amount of deflection variation in the case where, if i-th of hydraulic pressure sensor measure be apart from water surface depth value
Hi, then the array constituted is { H1, H2, H3......Hi}；After amount of deflection variation occurs for hawser with there is ship to pass through,
If hydraulic pressure sensor measure apart from water surface depth value be hj, the array of composition is { h1, h2, h3......hj, then hawser is scratched
Spend offset Δ h are as follows:
Δ h=Hi-hj
By the way of multiple spot installation, floating body is mounted on by each ultrasonic sensor, making hawser, up shifted by delta h reaches
To horizontal position, by the spacing H for constantly observing hydraulic pressure sensor everywhere and the water surfaceiTo increase and decrease the quantity of floating body, composition floating body
Compensating module works as HiValue close to it is consistent when then hawser integrally reach equilibrium state；
Step 5: building pivot angle monitoring modular；
Two-dimension tilt angle sensor is mounted on hawser center, pivot angle monitoring modular is constituted, to the left and right pivot angle of hawser
ΔθxWith upper and lower pivot angle Δ θyIt is monitored, when hawser centered horizontal, pivot angle Δ θx=Δ θy=0, when hawser occur left and right or
When downward shift, Δ θ is judgedx、ΔθyWith effective measurement angle θ of two-dimension tilt angle sensorEffectivelySize, as Δ θx、ΔθyGreatly
In θEffectivelyWhen, then two-dimension tilt angle sensor returns to an instruction controlled data processing module cancellation acquisition, when hawser pivot angle is normal
Then log-on data processing module is acquired when in range, guarantees the accuracy of data；
Step 6: data processing module is acquired, calculates；
Data processing module acquisition array of ultrasonic sensors module measures the spacing h and water of hawser and bottom of ship of opening the navigation or air flight
The drinking water value D=H-h of navigation ship is obtained by calculation in the spacing H of hawser and horizontal plane that pressure sensor module measures, completes
Drauht measurement.
It further, further include that the data processing module can monitor mould with pivot angle described in real-time response in the step 6
