At this time, by subjecting said data to correction processing on the basis of a tide level, shaking and underwater sonic velocity, accurate depth data can be formed. The data processed in the processing part 12 are stored in a data memory part 13 and the data read from the memory part 13 are converted to various display data by a data converting part 14 to be outputted to a display device 15 and a recorder 16.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sounding assistance device used in addition to an acoustic sounding device.

[0002]

2. Description of the Related Art A conventional sounding device is provided with one or a plurality of ultrasonic wave transmitters / receivers arranged in a row, and the respective depths at the wave transmitter / receiver installation locations are measured and recorded on roll paper by a pen recorder. It is portable and relatively compact.

[0003]

However, since only the depth information is drawn on the recording paper and the position information of the measuring point is not known, it is not possible to create, for example, a contour contour map with this sounding device. To achieve this, a positioning device for knowing the position of the ship itself, a direction sensor for knowing the bow direction, and for accurate measurement, hull movement measurement, tide level measurement, and submersion of a disk in water. It is necessary to measure the speed of sound in water by performing a bar check, and 2
In order to display it as three-dimensional map information, these data have to be organically combined, so that the system becomes considerably large and naturally expensive.

The present invention has been made in order to solve the above-mentioned problems, and by adding it to the current bathymetry device, the measurement data from the bathymetry device is processed to produce a contour map,
It is an object of the present invention to provide a bathymetry support device capable of displaying a depth map, a cross-sectional view, a track map and the like.

[0005]

A bathymetry assisting apparatus of the present invention is an apparatus used in addition to a bathymetry apparatus, which is at least a depth from a bathymetry apparatus, a ship position from a positioning apparatus, and a heading from a heading sensor. A data processing unit that creates depth data including position data based on each of the data, a data storage unit that stores the created data, and a data conversion unit that converts the stored data in the data storage unit into desired display data, And a display for displaying the display data.

[0006]

According to the apparatus having the above structure, various desired displays can be obtained based on the data measured by the conventional sounding device, and the display examples will be described in the following embodiments. As described in claim 2, the tide level, the speed of sound in water,
Accurate depth information can be obtained by receiving at least one of the vibrations of the hull and correcting the depth data.

[0007]

1 is a control block diagram showing an embodiment of the apparatus of the present invention. Reference numeral 1 denotes a sounding device, which includes three ultrasonic wave transmitters / receivers 2, a depth processor 3 for calculating the depth from the received signals from the ultrasonic wave transmitters / receivers 2, and a processing signal from the depth processor 3 to roll paper. The recording machine 4 is provided for recording. 5 is
Positioning device for measuring own ship position, 6 speedometer for detecting ship speed, 7 direction sensor for measuring heading of heading, 8 tide level detector for detecting tide level, 9 swaying (rolling) of hull , Pitching and heat sung) detection. Reference numeral 10 denotes a keyboard, which is used when inputting the underwater sound velocity obtained by the above-mentioned bar check or inputting various setting data.

The data from each of the above devices is supplied to the data processing unit 12 via the interface 11. In this data processing unit 12, based on each of the above data,
Depth data including position data is created. At that time,
Accurate depth data is created because it is corrected by tide level, shaking, and sound velocity in water. A data storage unit 13 stores the data processed by the data processing unit 12. A data conversion unit 14 converts the data read from the data storage unit 13 into various display data as described below. 15 is an indicator, 16 is XY
It is a plotter recorder.

A display example of this device will be described below.
FIG. 2 shows a track map used as a ship maneuvering assistance when creating a seabed topographic map of the seabed by this device. The track A is displayed, the current position is displayed by B, and the left end of the display screen is displayed. When a ship is displaced vertically from the planned course of a predetermined pitch width on the display screen, the direction of displacement from the displacement amount is displayed. If there is no displacement, the marker is displayed at position C. Is displayed, but when the ship shifts upward on the screen as shown by the broken line, the marker moves to the position D. Instead of drawing a track, the display screen may be divided into a large number of areas in a grid pattern, and the area on the display screen corresponding to the sea area where the ship has passed may be displayed in a different color. Good.

FIG. 3 is a contour map created by this apparatus and displayed on the display unit 15, which is displayed in different colors according to the depth. When the contour map is printed out on the recording machine, the depth is directly written in each contour line instead of the color-coded display.

FIG. 4 shows a depth chart, in which the depth measured for each predetermined grid area is two-dimensionally displayed. This depth map can be displayed on either the display 15 or the recorder 16.

In FIG. 5, the depths measured by the three ultrasonic wave transmitters / receivers 2 are digitally processed by the data processing unit 12, then sent back to the sounding device 1 and printed out by the recorder 4. The oscillation line and the submarine line are clearly shown by one line. On the other hand, FIG. 6 shows the same detection data processed only by the sounding device 1 without being digitally processed and printed out on the recording machine 4. In this case,
The exact depth cannot be known because of the tailing of the oscillation line and the seafloor line. The keyboard 10, the interface 11, the data processing unit 12, the data storage unit 13, and the data conversion unit 14 can be replaced by a personal computer, so that the present apparatus can be provided at low cost.

[0013]

As described above, according to the present invention, various desired displays can be obtained by processing and processing the data measured by the sounding device together with the positioning data and the like by the assisting device. Further, by correcting the depth data with at least one of the tide level, the speed of sound underwater, and the shaking of the hull, accurate depth information can be obtained.
