Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Fig. 1 is the hardware circuit diagram of total system of the present invention, hardware system of the present invention comprises underwater acoustic transducer 1, be connected with echo sounder 2 on the underwater acoustic transducer 1, be connected with USB digital to analog converter 3 on the echo sounder 2, signal input memory controller 4 with after 3 conversions of USB digital to analog converter is connected with GPS receiver 5 on the memory controller 4.
The workflow of native system is as follows:
The first step: as under water, the gps antenna frame on the quarter or side unobstructedly, deck is opened switch with the underwater acoustic transducer of fish finder, and when the fishing boat operation, system accepts ultrasound echo data with active mode work, and gps data;
Second step: echo data by high speed USB mould/number conversion plate, is carried out mould/number conversion of signals, show echoed signal, and digital signal is stored in the computer hard disc, so that further handle;
The 3rd step: read gps data, show information such as vessel position;
The 4th step:, realize handling ultrasonic echo data and gps data, and the two is combined by software module, make and show three-dimensional underwater information, and from echoed signal, put forward living resources such as separating the underwater topography and the shoal of fish, show respectively, and make function such as dimensional topography database.
Fig. 2 is the composition structural representation of USB analog to digital converter of the present invention, in order to realize cheap miniature high-speed, we reduce to minimum degree with the element number, the digital-to-analog conversion plate has only comprised a mould/number controller 32 and a USB2 controller 31 that comprises CPU, as shown in Figure 2, power supply is provided by USB connector, and the memory portion of change-over panel replaces by computer software module, by developing USB firmware and driver alone, realizes that the data after high speed analog-to-digital conversion and the conversion transmit.
Software systems constitute: owing to do not have the memory storage data on the digital-to-analog conversion plate, the A/D translation data need be transferred to immediately in the memory controller and use processing for apparent control program.Show the control program and need wait for the arrival of A/D translation data always, and general graphic user interface (GUI) windows application program is only managed with a thread, if this thread is used to wait for the A/D translation data, will cause GUI information to stop up so, before the A/D translation data arrives, the user carries out any operation to GUI and can not respond, and the illusion to the user causes program crashing influences the application of program.
For the processing and the user's operation that make data can be carried out simultaneously smoothly, three-dimensional fish finder shows control software and uses the mode of multithreading to manage, a main thread, a USB digital-to-analog conversion data read thread (thread 1) and a gps data read thread (thread 2).When USB interface was connected with the A/D change-over panel, thread 1 just began to monitor the arrival of A/D translation data, when data arrive, just was sent to main thread, allowed main thread processes and displays and record.And reading of gps data also adopts the thread of exploitation separately to control, the delay of the data that can dip like this, the precision of raising positional information.
Fig. 3 is that the software and hardware of total system of the present invention is formed structural representation, and Fig. 4 is a software system structure block diagram of the present invention, and its workflow is as follows:
1. initialization, the USB number is touched the change-over panel interface initialization, the initialization of gps data receiving interface, user interface initialization etc.;
2. startup main thread, promptly graphical user interface thread, the user can operate its interested option, as 3-D view demonstration, two dimension view demonstration, windows display, gain-adjusted, current location inquiry etc.;
3. enable sub-thread 1 and thread 2, the arrival of thread 1 monitoring A/D translation data when data arrive, just is sent to main thread, allows main thread processes and displays and record; Thread 2 is used for the monitoring GPS data stream;
4. EOP (end of program) withdraws from.
Fig. 5 gathers mould/logarithmic data workflow diagram for system of the present invention by USB.
GUI imageization user interface program function comprises:

As shown in Figure 6, adopt the curtain shape to show echoed signal in real time, the echo that each emission is returned shows the method for the detection of a target in vertical direction in real time.
6, curtain shape echoed signal combines with the GPS position display
Curtain shape echoed signal is in real time in conjunction with the method for GPS positional information with demonstration underwater 3 D environment.
7, database function
Echo data, GPS position data, the method for catch data and other all user's interest information use data-base recordings and inquiry, interface prompt, demonstration.
The algorithm that separates aquatic plants such as seabed and marine alga with Johnston by the real dress Sabol of USN shows, this algorithm is undesirable in the aquatic plant separation effect that distributes when dense.The present invention will be by high-speed sampling, and digital detection utilizes pulse width, seabed involuting wave signal intensity profile, aquatic plant echo strength to distribute and the features such as height of aquatic plant are extracted seabed, the shoal of fish, marine alga information out.
The three dimensional representation of landform generally represents with triangular mesh, and leg-of-mutton quantity increases with square level of the length of side, how under little distortion condition, represents that terrain data is most important at a high speed.The three-dimensional algorithm of expression at a high speed of the present invention's exploitation, the part diabolo that topographic relief is big segments guarantees authenticity, and the little part of topographic relief with low level of detail, to reduce leg-of-mutton quantity, has realized the high-speed real-time demonstration.
Echoed signal under the windows display different gains is convenient to analyze the detection of a target, and can show track line.
Information three-dimensionals such as marine alga show, adopt the display mode of echo curtain that target in the water such as marine alga is presented on the dimensional topography, can show the three-dimensional observation image fast in real time.
More than demonstration and description is ultimate principle of the present invention, principal character and major advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the instructions just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
