Description
Technical field
The invention belongs to underwater sound field, and in particular to be related to a kind of subglacial depth of water measuring method.
Background technology
In the last few years, China ocean correlation cause develop rapidly, every hydrologic parameter turn into development in it is indispensable because
Development and marine exploration and development of the measurement of depth where element, wherein underwater hiding-machine either to naval equipment all have quite big
Meaning.With electronic technology, the development of sensor technology, people require more and more higher to the real―time precision measurment of the depth of water.It is super
Sound wave or pressure sensor are the two methods of depth under water measurement, and the former is sounded the depth of the water using the echo technique of sound wave,
The latter is that the depth of water is converted using the hydrostatic pressure in water.There are respective advantage and disadvantage respectively, ultrasonic wave carries out subglacial
Measurement have the characteristics that good directionality, penetration capacity are strong, energy is high, high sensitivity, inspection speed it is fast, harmless, and
It can be propagated in different mediums.Exactly these characteristics of ultrasonic wave, make ultrasonic wave be widely used in the inspection of multiple fields
Survey and measure.And pressure sensor is then the characteristics of increase using hydraulic pressure as the depth of water increases, pressure sensor is put into sea
Bottom, the seawater depth of water is calculated according to the pressure value that sensor returns.And subglacial water-depth measurement meets the independence of underwater hiding-machine depth measurement
Property and concealed requirement.The important content that reliable subglacial bathymetric data is polar research activity is obtained simultaneously, for
Ensure that ship is also of great significance in polar region marine site navigation safety.
At present, using ultrasonic wave or pressure sensor when being sounded the depth of the water in ice face to measure, both need also exist for digging
Ice sheet is worn, because in the severe of polar region external environment condition, drilling through the method that ice sheet sounds the depth of the water has great difficulty.Therefore, we
Being badly in need of one kind not drill through ice sheet, so that it may the method to be sounded the depth of the water in ice face, reach and reduce staff for a long time, reduce room
Contingency rate caused by outer work.
The content of the invention
The invention provides a kind of method to be sounded the depth of the water in ice face, can significantly be reduced under severe polar region environment
In the time of outdoor measurement, staff is largely reduced for a long time in the contingency rate caused by outside work.

Being rebounded in the presence of the connecting rod spring below of ball, spring and its expansion plate are also pulled up therewith, when reaching the breach of wheel disc,
The spring ejection fixing chuck plate of compression in expansion plate, blocks wheel disc, to prevent secondary bounce-back of the shot in ice face；
When step 3 taps again, cam rotation is driven while lifting rocking handle, cam is pushed outwardly the gear of spring elongation
Plate, the clamp top in expansion plate is returned, expansion plate returns to original position, to prepare for the next use；
After step 4 knocking produces, signal a part of first is broadcast to the ice sheet wave detector conduct on side by ice face
Trigger signal, another part signal is refracted into seawater after ice sheet is propagated, by ice sheet lower surface, after sub-bottom reflection, by ice
The refraction of layer lower surface, is propagated into ice sheet, and device reception is detected after reaching ice sheet wave detector；
Step 5 taps once, after wave detector receives time-domain signal, is stored；After storage, via wireless transmission mould
Block reaches DSP signal processing modules；
The time-domain signal that step 6 DSP signal processing modules receive should be divided into three sections, and first paragraph is trigger signal, and second
The signal that section reflects for ice sheet, the 3rd section of signal for sub-bottom reflection；Because the signal of ice sheet reflected signal and sub-bottom reflection is same
When time for being propagated comprising echo in ice, twice subtract each other the time as signal in water transmission；DSP processing unit meters
The adjacent time inter of second segment and the 3rd segment signal is calculated, bathymetric data then can be obtained by the velocity of sound in water；
After step 7 processor obtains bathymetric data, TFT display screens are displayed it to.
Described ice sheet wave detector, ice sheet wave detector are by STM32 single-chip microcomputers, acceleration sensor module, memory module
Formed with wireless transmitter module；Sound wave in ice sheet gathers via acceleration transducer, by AD conversion, STM32 monolithics afterwards
Machine is handled and stored, and is finally launched by wireless module to DSP signal processing modules and is calculated and be shown.
