Description
1st, technical field：
The present invention relates to microcontroller embedded automatic test technology field, is led more particularly, to oceanographic survey e measurement technology
Domain.
2nd, background technology：
Marine economy and ocean military developments have very important strategic importance current, and many countries have begun to add
Fast research and development paces, to take the good opportunity in being competed in marine resources.The acoustic characteristic of bottom sediment (refers mainly to the velocity of sound
And acoustic attenuation coefficient) study for military marine environment investigation, multibeam calibration, seabed resources exploration and development and seabed ring
The fields such as border monitoring have important application value.Such as：Shallow sound field is analyzed and researched and sonar operating range calculates, seabed is shallow
Layer engineer geological prospecting and submarine oil platform engineering construction of base etc., it is desirable to provide seabed sediment acoustics property data, because
This, the Research of Acoustic to bottom sediment is in the indispensable research in the field such as marine economy and ocean military developments
Hold.
Sediment acoustics characteristic test room measurement is one of main method of current research seabed characteristic, that is, is being tested
The columnar deposit sample gathered in seabed is measured in room, has the characteristics that instrument and equipment is simple and convenient to operate.To sea
Bottom samples and analysis, it is necessary to the seabed depth of accurate measurement submarine sampling point, because the depth of water is one of sample house site important
Index.Traditional method is sounded the depth of the water with the method for release rope, and the measurement result of this method is inaccurate.Because ocean
In ocean current speed V be present, the rope discharged with sampler is not to be in plumbness in ocean, but along ocean current
Direction, often in a kind of inclined state, it is clear that it is larger error be present to replace vertical line with parallax, such as Fig. 1 institutes
Show, parallax rope is L, and vertical line is seabed depth h.
3rd, the content of the invention：
Measured it is an object of the invention to provide a kind of integrated Seafloor sediment sampling and the sampling erect-position seabed depth
Device.Single chip control unit (2) is used as core, sends control signal, control drive amplification circuit (6) produces impulse wave,
Amplified pulse signal driving sonac (1) launches ultrasonic wave to sea level, and ultrasonic wave reaches sea level back reflection and returned
Come, received by sonac (1), the echo-signal received is sent to single-chip microcomputer through data acquisition module (3) conditioning amplification
Control unit (2).Single chip control unit (2) record sensor (1) launches ultrasonic wave to the time interval for receiving ultrasonic wave, leads to
Calculating is crossed, obtains the seabed depth in sample house site.Sonac (1) is to launch the structure being integrated with reception, small volume,
It is easy to seabed installation and sealing.The temperature of temperature sensor (4) detection seawater, the shadow to compensation temperature to sound velocity in seawater are set
Ring.The method of this measurement seabed depth, it is as a result more accurate than tradition by measuring the method for connecting sampler rope lengths.
The comprising modules connection of device is as shown in Figure 2.
The present invention operation principle be：
(1) present invention is on the basis of Conventional gravity formula sampler, comprehensively utilizes supersonic sounding principle.The present apparatus is complete
While into Seafloor sediment sampling, moreover it is possible to the depth in the accurate measurement sample house site seabed.On ship, pass through lifting machine
Gravity type sampler is put into seabed, (now, lifting machine rope is in relaxation shape when sampling is completed in sampler contact seabed
State), start single chip control unit (2), single chip control unit (2) is put according to predetermined program, hair pulse signal to driving
Big circuit (6), drive amplification circuit (6) driving sonac (1) is to emission of sea surface pulse train ultrasonic wave, while single-chip microcomputer
Control unit (2) starts timing；After ultrasonic wave reaches sea, part refraction, another part is reflected back seabed, is passed by ultrasound
Sensor (1) receives, and sonac (1) receives the ultrasonic signal reflected and is sent into data acquisition module (3), through data
Processing is re-fed into single chip control unit (2), and single chip control unit (2) stops immediately once receiving ultrasound echo signal
Timing.According to the propagation law of ultrasonic wave in the seawater, the acoustic propagation velocity in seawater is relevant with temperature, pressure and salinity, its
Middle temperature influences maximum on the velocity of sound, therefore this test device considers this factor of temperature, sets temperature sensor (4) to detect sea
The temperature value of water.
According to velocity of sound formula in seawater：C=1450+4.21T-0.037T2,
In formula, C is sound velocity in seawater, and T is ocean temperature,
According to the propagation formula 2h=C of sound wave*t
So as long as measure time interval t, and the temperature T of seawater,
Acoustic propagation distance h=(1450+4.21T-0.037T2)*T/2,
This required h value, it is exactly the seabed depth in sample house site.
4th, illustrate：
Fig. 1 is the fundamental diagram of the multifunctional gravity formula marine sediment sampler.Curve L is traction sampler in figure
Rope, traditional method is exactly according to depth of the length of rope as seabed；H is actual seabed depth, and V is marine ocean
The speed of stream；O be release sampler position, O2For submarine sampling point.
Fig. 2 is the composition figure of multifunctional gravity formula marine sediment sampler, it is main comprising driving sonac (1),
Single chip control unit (2), data acquisition module (3), temperature sensor (4), lithium battery power supply (5), drive amplification circuit (6)
