SU94500A1 - Method for the production of depth measurement by means of an echo sounder or other device installed on a measuring vessel - Google Patents

Description

C. probes are measured by echo sounder by means of an echo sounder that when determining the coordinates of individual survey points during a survey trip, serifs are made by means of a mezzula or a theodolite with ;; temporarily inserting conditional signs to the sonar tape.

Such methods require the vessel to move in line, while the plates of the IOD1ULL relief are not empty, for example, due to the demolition of the vessel from the cross-section and because of its puncture marks (osopeppo in case of sharp laces), the measured points are plotted with a significant deviation from the site. corresponding to their name.

The methods of depth measurement with the use of echo sounders, which have a lenses mechanism, are specially co-instrumented. where the task of moving the echo sounder tape is solved at a speed proportional to the speed of the displaced judge. moving along a linear tack defined by a target are known.

In order to use such an echo sounder (when it is not necessary to determine the positions of intermediate points of the tacks) along with the well-known echoes, it is necessary to provide a yoTcTpoiicTBO cam coupling to separate the rotary mechanism from the ratchet mechanism to adapt it to the drive with a uniform stroke, not associated with a radiolag and not required to use it for such measurements. In the case, the 1enta echo. Moves at a random rate that is not related to the speed of the vessel, and does not have a distance mark of distance.

The proposed method of depth measurement by means of an echo sounder differs from that indicated by the fact that, with the determination of the coordinates of the measuring points, the echo sounder tape simultaneously with the depth recording automatically and continuously mark the distance from the iromeric vessel to the geodesic points, the ship can move along a curved course.

FIG. 1 shows a scheme for implementing the depth measurement method; in fig. 2 - echo sounder tape with recording of the depth curve.

On a survey vessel 1, equipped with a conventional recording echo sounder 2, a master station of radio station 3 is set up of one of the existing t-yps. On the coast, in two}; x, oriented to the existing geodesic set, they establish their relative camps; 4 and 5, paccyorfjftie between which (the basis ") is known. Go out from 1 and / 2 meters between the measuring vessel and reflective stations 4 and 5, the radial on the measuring vessel continuously records the increment ± A / on the echo sounder tape by applying electrical signals to the phase difference recording recorder.

As another recording option on the echo sounder tape (i and iz), the use of impulses generated by the radioagent after every ± L / m increments of the distance between the reference and the reflecting stations of the radial is proposed. In each such impulse, the relay acts on one of two paired (dual) power lines 6 or 7, which, using spark or other means, mark the change in the distance on the corresponding lateral longitudinal edge of the chart paper with each actuation of the relay, i.e., through certain values of the radius difference -vectors, counting from the location of the surveyed vessel with respect to the reflecting stations. One of the feathers of each pair 5 and 7 marks an increase (-f L /) of the distance, respectively, / 2 or / 1, and the other pen of the same lara notes a decrease (-L /) distances / 2 or /.

An example of such a change in distance is shown on the edge of the tape with a feather 7.

Consequently, for any of the two above described options for recording distances, three records are obtained simultaneously on the echo sounder tape, namely, the depth and distance to the two reference points of the basis.

Before the depth measurement, the distances / 1 and / 2 from the surveyed site / to the reflecting stations are determined by geodesic. The echo sounder and the radial log are put into operation, after which the vessel departs for a survey flight.

As an example in FIG. 2 shows a sample of the batigram, on which the depths are recorded and the distance from the boat to the reflecting stations is marked. Belt speed 1, 50 mm / min; the speed of the boat V at 6 km / h; The radar band and, consequently, the distance between the bars of the tape correspond to ± L / 10 m.

The proposed method of measurements also makes it possible to carry out 1P ketazh geodetic works on the edges by installing the geodesic marks when the vessel approaches the shore.
