After the high tide, as shown in Figure 5 (b) the buoyancy body 215 is floating under the buoyancy of sea water, the rotary arm 214 is also spread upward along the buoyancy body 215. At this time, the rotating shaft 213 connected to one end of the rotating arm 214 is rotated at a predetermined angle, and the laser 230 is also rotated by the angle to irradiate light. Of course, the light receiving module 240 receives the light irradiated by the laser 230, the water level information according to the light receiving position is transmitted in real time to the information transmitter 300 as tag information. Here, since the current position of the buoyancy body 215 corresponding to the light receiving position of the light receiving module 240 has already been confirmed through a test measurement when the surveyor 200 is manufactured, the position of the buoyancy body 215 through the light receiving position Is naturally confirmed. On the other hand, since the buoyancy body 215 floats on the surface of the seawater, the position of the buoyancy body 215, that is, the height from the surveyor 200 to the buoyancy body 215 becomes the water level.

Since the water level information for the light receiving position may be different according to the instrument 200, the information transmitter 300 will need to check the transmitter 200 by checking the transmission path of the received water level information. Therefore, each instrument 200 is a unique code for the identification is set, the unique code is transmitted with the water level information will be utilized for the water level information identification.

As shown in FIG. 5C, the buoyancy body 215 is positioned at the highest point during high water, and the survey instrument 200 transmits the light receiving position of the light receiving module 240 as the water level information to the information transmitter 300.

Meanwhile, the vibrator 220 installed in the support 211 vibrates the housing 212 while continuously operating in the process of supplying power from the battery 260. As shown, the enclosure 212 is disposed to be inclined to correspond to the bottom of the seabed forming a slope, the tip is an open shape. Therefore, during high tide, the soil can be easily introduced into the enclosure (212). However, at low tide, the rear end is blocked, so that the earth and sand may not be easily escaped, and when the rotary arm 214, which has been extended upward, is folded into the enclosure 212, the soil is completely deposited by the soil deposited on the enclosure 212. There may be a problem with folding. In order to solve this problem, the vibrator 220 vibrates the enclosure 212 to lift up the deposited soil, and the excreted soil at low tide so that it can be easily discharged to face the corresponding force.

FIG. 6 is a diagram illustrating a switch line of the instrument, FIG. 7 is an exploded perspective view illustrating a switch structure of the instrument, and FIG. 8 is a diagram schematically illustrating an operation of the switch.

The instrument 200 is a device that operates by receiving power from a finite battery 260, and in the case of low tide, since it is not necessary to measure the water level of the seawater and transmit the corresponding water level information, the water level is measured due to the inflow of seawater. It is desirable to start the operation only when necessary.

To this end, the surveyor 200 according to the present invention further includes a switch 216 interlocking with the buoyancy body 215.

As mentioned above, the buoyancy body 215 is rotatably fixed to the other ends of the rotating arms 214 and 214 'where the pair face each other, and for this purpose, the rotating arm pipes 214a to the rotating arms 214 and 214', respectively. The protrusion is formed, and the buoyancy body 215 is provided with a rotary tube 215a whose both ends are rotatably engaged with the rotary shaft tube 214a, respectively. Here, the rotary shaft tube 214a and the rotary tube 215a are fixed to communicate with each other, and the parts rotatably contacted are sealed for waterproofing.

The switch 216 is a conductive tube 216a made of a conductive material in the rotary shaft tube 214a formed on the rotary arms 214 and 214 ', and an insulating tube 216b made of an insulating material in the rotary tube 215a. It consists of. Here, the insulating portion (a) is formed in the longitudinal direction at one point of the conductive tube (216a), the conductive portion (b) is formed in the longitudinal direction at one point of the insulating tube (216b), a pair of rotary shaft tube ( When 214a is engaged with both ends of the rotary tube 215a, the outer surface of the energizing tube 216a is fixed to be in close contact with the inner surfaces of both ends of the insulating tube 216b, respectively.

As a result, when the buoyancy body 215 does not float at the time of low tide and reaches the bottom as shown in FIG. 8 (a), the rotary tube 215a rotates along the buoyancy body 215 and the The energizing part (b) is in contact with the insulating part (a) of the energizing tube (216a).

Accordingly, the switch 216 is in an open state in which the pair of energizing tubes 216a are not energized with each other.

As shown in FIG. 8 (b), when the tide or the ebb tide is introduced into the seawater that can float the buoyancy body 215, through which the buoyancy body 215 floats to rotate the rotary tube 215a. At this time, the energization part b of the insulated tube 216b is in contact with parts other than the insulator part a in the energization tube 216a. Therefore, the switch 216 is in the closed state which energizes a pair of energizing pipes 216a.

As shown in FIG. 8C, the buoyancy body 215 reaches the highest position at high water, and the rotary tube 215a and the rotation portion b of the insulated tube 216b are rotated by the rotary tube 216a. ) Contacts parts other than the insulation part (a). Therefore, the switch 216 is in the closed state which energizes a pair of energizing pipes 216a.

Subsequently, the rotary arms 214 connected in series imply a power line PL connected to each of a pair of conducting pipes 216a, and the power line PL is led into the box 212a to be connected to the battery 260. Connected. In this case, the vibrator 220, the laser 230, the light receiving module 240, and the transmission module 250 are connected in parallel to the power line PL to receive power from the battery 260.

9 is a view showing a drawing structure of the coastal terrain used by the digital map production system according to the present invention, will be described with reference to this.

The instrument 200 is installed, and the installation distance L from the coastal road to the instrument 200 is measured and input.

At high tide, surveying and inputting the distance to the coastline from the point where the instrument 200 is located, and then input the water level at this time. The distance D to the shoreline with respect to the current water level H can be calculated based on the input distance and the water level.

As a result, when the light receiving module 240 of the instrument 200 transmits the water level information according to the light receiving position of the light emitted by the laser 230 to the information transmitter 300, the calculation module 320 of the information transmitter 300 is Check the current water level (H) from the water level information, calculate the distance (D) between the coastline and the point where the instrument 200 is located, and subtract the distance (D) that is the result of the calculation from the installation distance (L). The value S is derived.

The derived position values S are identified by the unique code of the instrument 200, and averaged over a plurality of position values S to calculate the final position values to be included in the information signal.

The calculated position value is completed with an information signal together with the position information identified in the GPS 310, the transmission module 340 randomly wirelessly transmit the information signal.

The numerical map outputter 100 receives the information signal, and the correction module 150 checks the corresponding map image according to the location information included in the information signal and according to the position value, the shoreline at the corresponding position of the map image. After drawing the image, blue is painted outside the shoreline image.

The modified numerical map image is finally output as the modified numerical map through the output module 160.

10 is a view schematically showing the operation of the gas tank connected to the balloon of the instrument according to the present invention, Figure 11 is a view showing a state in which the balloon is gas-inflated and raised, see this I explain it.

The water level information transmitted from the instrument 200 is stored in the operation history DB 350 of the information transmitter 300 over time, and the management module 360 checks the history information stored in the operation history DB 350. The rotary arm 214 rotates by the flow of sea water, and its position becomes maximum at low water or high water. However, as the soil is continuously deposited on the enclosure 212, the rotary arm 214 may not be fully folded into the enclosure 212 even at low tide, and may be buried in the soil before the rotary arm 214 is unfolded. have. Of course, when such a situation occurs, the water level information transmitted to the information transmitter 300 may be a value exceeding the limit. In addition, water level information may not be received within a predetermined time due to an abnormality of a device such as discharge of the battery 260.

When such problems occur, the management module 360 checks the history information on the problem in the operation history DB 350 and transmits a control signal for opening the gas tank 270 to the instrument 200.

The gas tank 270 of the instrument 200 receiving the control signal opens the outlet to exhaust the filled gas. Since the gas tank 270 is filled with gas at high pressure, the gas filled in the gas tank 270 will be exhausted at a high speed even with the opening of the outlet. For reference, in the embodiment according to the present invention, the gas is applied to a gas lower than the density of air, and helium may be applied. Here, the outlet may be a conventional gas discharge structure in which the opening and closing is remotely controlled, the gas discharge structure is known, because it is a common technique, a detailed technical description of the outlet is omitted.

On the other hand, the gas tank 270 is installed in the housing 212, the outlet is located in the exhaust hole 212c opened to the outside.

The balloon 280 is made of rubber having elasticity, and the inlet 281 is made of a tubular shape of a rigid material which is inserted into the exhaust hole 212c and fixed to be detachable. Here, the inlet 281 is configured to open and close to one side, the opening and closing plate 282, the opening and closing plate 282 is a structure that is opened by the force of the gas exhausted from the outlet and closed by the air pressure in the balloon 280. To this end, a hinge 282a connecting to the inlet 281 is installed at one end of the opening and closing plate 282 so that the opening and closing plate 282 rotates inward.

As shown in FIG. 10A, the inlet 281 of the balloon 280 is forcibly inserted into and fixed to the exhaust hole 212c of the housing 212 so that when the gas is exhausted from the outlet, the gas enters the balloon 280. Can be introduced. Subsequently, the gas pushes the opening and closing plate 282 by the powerful output and enters the balloon 280, and the balloon 280 expands by the air pressure of the gas.

At this time, when the balloon 280 is underwater, the inlet 281 escapes from the exhaust hole 212c by its own buoyancy, and when the air is low due to low water, the balloon 280 floats due to the low density and the exhaust hole 212c is released. The entrance 281 will escape from it.

Since the balloon 280 is fixed to the main body 210 via a string 283 connecting the inlet 281 and the housing 212, the balloon 280 is not lost by seawater even when the inlet 281 is separated from the exhaust hole 212c. . In addition, since the air pressure in the balloon 280 strongly closes the opening and closing plate 282, the gas inside the balloon 280 is not exhausted to the outside.

Eventually, since the balloon 280 is separated from the problem measuring instrument 200 and floated in the water or floated in the air, the manager can accurately check the position of the measuring instrument 200 even at a long distance, thereby measuring the instrument 200. Checking whether a problem occurs and the location of the instrument 200 has an effect that can be quickly identified.

A further embodiment according to the present invention further improves the structure of the inlet 281 that secures the balloon 280 as shown in FIGS. 16A and 16B, and thus the gas filled into the balloon 280. To prevent leakage.

In the disclosed embodiment, the structure of the soft rubber balloon 280 and the inlet 281 made of a hard synthetic resin is not clear, so the boundary is ambiguous, so that the possibility of implementation and the leakage of the filled gas are continuously maintained. It was a problem.

Thus, in a further embodiment according to the present invention to facilitate the filling of the gas inside the balloon 280 while completely sweeping up to these problems, and even if separated after the filling so that the filled gas does not easily leak to improve the efficiency of the survey operation It is configured to improve.

To this end, in the present invention, as shown in FIG. 16, the inlet 281 for fixing the balloon 280 is divided into an inner support 800 and an outer fixer 900.

At this time, both the inner support 800 and the outer fixing 900 are manufactured by injection molding a synthetic resin.

In addition, the inner support member 800 is formed in a cylindrical shape, and a round portion 810 extending upward with a predetermined curvature in a radial direction is formed at an upper end thereof.

The round part 810 is a means for guiding the seat 810 to be stably seated and supported when the balloon 280 is inflated.

In addition, the inner engaging jaw 820 is protruded along the circumferential direction on the lower outer circumferential surface of the round part 810 of the inner supporter 800.

Therefore, before the gas is filled, the balloon 280 passes through the inner hollow of the inner supporter 800, and then the lower opening of the balloon 280 is opened as shown in FIG. 16B. After being turned over, it can be arranged in a form that is covered in an outward direction from the lower end of the inner support 800 to the top.

The reason for this configuration is to seal the source so that the balloon 280 is coupled with the inner supporter 800 so that a leakable part does not occur.

On the other hand, the outer stand 900 is fitted to the lower end of the inner support 800 in the state in which the lower end of the balloon 280 is inverted in the form of the inner support 800 is turned upside down of the balloon 280 As a means for completely pressing tightly the part, the overall shape is cylindrical, but is formed in the form of a double tube having a fitting groove 910 of the 'U' shape on the outer peripheral surface.

However, it is not a complete double pipe, but a double pipe with an open top.

At this time, the inner support member 800 is fitted into the fitting groove 910 constituting the double pipe.

Accordingly, the width of the fitting groove 910 should correspond to or be slightly smaller than the thickness of the inner supporter 800 plus the thickness of the balloon 280.

That is, because the inner support 800 with the end of the balloon 280 enters the fitting groove 910, the balloon 280 is pressed to have a tight fixing and sealing properties.

In addition, an outer catching jaw 920 protruding toward the fitting groove 910 protrudes from an outer upper end of the outer fixing stand 900, and the outer catching jaw 920 is caught with the inner catching jaw 820. It is also formed in the form of a strip in the circumferential direction so as to be fixed.

In addition, the depth of the fitting groove 910, more precisely the distance from the outer locking jaw 920 to the bottom surface of the fitting groove 910 to fix the balloon 280 more tightly is the inner locking It is preferable that the distance from the jaw 820 to the lower end of the inner supporter 800 is equal to or smaller than the thickness range of the balloon 280.

Thus, when fitted, the balloon 280 can be pressed in close contact.

In addition, a valve catching jaw 930 is formed at the upper end of the inner circumferential surface of the outer fixing stand 900, and the check valve 940 is closely attached to the valve catching jaw 930 under an O-ring 950.

The check valve 940 is preferably inserted into the valve engaging jaw 930 with the O-ring 950 interposed therebetween after being inserted through the lower opening of the outer fixing stand 900.

Due to this configuration, the problem that the inlet 281 is separated from the balloon 280 when filling the gas in the balloon 280, and the lower end of the balloon 280 is stable and the inner support 800 and the outer fixing stand Since it is sealed by 900, there is no possibility of leakage of the filled gas.

In addition, the check valve 940 fixed to the inner diameter of the outer fixing stand 900 is opened only in the direction to be supplied toward the balloon 280 and closed in the reverse direction, so gas filling is easy, but gas backflow does not occur, Enable breakthrough gas filling

In addition, the inner support 800 and the outer fixture 900 is fixed to each other while being fixed to the bottom of the balloon 280 in close contact therebetween the problem of gas leakage is blocked.
