Embodiment
For further understanding technology contents of the present invention, characteristics and effect, exemplify following examples now, and be described with reference to the accompanying drawings as follows:
Water-bed vegetation acoustic detection device, comprise sonic depth finder 1, GPS orientator 3, computer 4, mouse 5 and computer software, sonic depth finder 1, GPS orientator 3 are connected with computer 4 by serial ports by data line, sonic depth finder 1 utilizes reflection sounding plant border, GPS orientator 3 to judge position coordinates, computer software collection, editor and deal with data, computer show that the vegetation data of surveying the district are that numeral becomes figure.。
Embodiment 2
A kind of water-bed vegetation acoustic sounding method, utilize acoustic sounding and satellite positioning method, adopt the combination of sonic detector, GPS orientator, computer and software to survey, sonic depth finder is by the dark measuring plants of echo border, the GPS orientator is judged position coordinates, and data in real time is transferred to computer, computer software carries out data acquisition, editor and processing, forms to show the vegetation data of surveying the district.
The aggregate erection of sonic detector, GPS orientator, computer and software is in boats and ships, boats and ships are walked in a zigzag to survey in the survey district, on the trajectory that boats and ships are passed by, the acoustic reflection point position of reading by the single beam sonic depth finder, obtain numerous frontier points of vegetation under water position, these position lines obtain surveying water-bed vegetation border, district.
The specific implementation process of present embodiment is described as follows:
Select the vegetation investigation of high precision measuring instrument combination carrying out region, lakeside, the surveying instrument combination is placed on the fishing boat, make boats and ships walk " it " font at lakeside band enumeration district, on the trajectory that boats and ships are passed by, the situation of the acoustic reflection point that reads by the single beam sounder can obtain numerous frontier points of vegetation under water position, these position lines, be the vegetation boundary line at the bottom, region, lakeside, see Fig. 2.
What present embodiment adopted is the acoustic reflection principle, because sound wave is run into barrier reflection wave is just arranged, floral region under water, vegetation is positioned at water-bed mud face top, sound wave is beaten at the reflection spot on the water-bed vegetation can be positioned at different positions with the reflection spot of beating on water-bed mud face, because the end face that the underwater plant body forms is discontinuous, and jumps significantly, the echo signal that is reacted on the analog record paper is mixed and disorderly, and a continuous smooth bottom surface line is arranged below hash.Utilize these characteristics of sound wave, we can judge whether the bottom, somewhere has vegetation growth by the feature of analog record on the single beam sounder, its method is that reflection spot becomes level and smooth curve interval scale water-bed mud face, represent that this bottom, place does not have vegetation, have only when " burr " appear in reflection spot on the single beam sounder, just represent this bottom, place vegetation that growing, see Fig. 3.
Received by sounder through plant leaf blade or stem reflection back by the sonic depth finder emitting sound wave, can be according to the speed of the sound wave time that comes and goes and the sonic propagation in the waters of surveying, just can be the residing depth of water of blade or stem in the hope of the distance between blade or stem and the sounder.According to the continuous recording boats and ships trajectory coordinates of GPS, can accurately judge the coordinate of these plant frontier points.Thereby present embodiment utilizes acoustic measuring instrument, according to the difference of getting the position ready, has judged vegetation under this waters, place.
