The plate 131 and a plurality of receiving sensors 132 disposed in line along the plate 131.

The reception sensor 132 may be the same or similar to the first and second light receivers 111 and 121, and may also receive and detect an optical signal transmitted from the first and second light receivers 112 and 122. If present, various modifications may be made without departing from the scope of the following claims.

The elevating device 150 adjusts the height of the first and second communication modules 110 and 120 to accurately receive the optical signal horizontally transmitted from another neighboring geographic information collecting device, or vice versa. The nut 151 includes a screw 152 which is rotated by the driving of the motor 151, the driving motor 151, and a screw thread is formed on the periphery thereof, and a nut part 153a through which the screw 152 is threaded and threaded thereto. A platform 153 having a guide groove 153b formed to penetrate up and down side by side with 153a, and a guide 154 for guiding the shangdong of the platform 153 while movably penetrating the guide groove 153b. .

That is, when the drive motor 151 is driven, the coaxially connected screw 152 is rotated along the driving direction of the drive motor 151, and the screw 152 and the screw thread coupled to the lifting platform (154) supported by the guide 154 ( 153 moves up and down in accordance with the rotation direction of the screw 152.

In this case, the first and second communication modules 110 and 120 are fixedly disposed at both ends of the platform 153, and in particular, the second communication module 120 is connected to the plate 131 of the reception detection module 130. It is connected to the platform 153.

Meanwhile, the first communication module 110 may be fixed to the platform 153 so as to be rotatable with each other. For this purpose, the first communication module 110 constitutes the first hinge bracket 113 and the platform 153 of the platform 153. A second hinge bracket 153c connected to the first hinge bracket 113 is formed at one end thereof so that the first communication module 110 and the lifting table 153 are pivotally connected with respect to the rotating shaft (not drawn out).

The first fixing stand 181 is to be fixed so that the control box 141 can rotate around one axis, for this purpose, the control box 141 is formed with a first pivoting groove (141a) on the side, The first rotation shaft 181a rotatably engaged with the first pivoting groove 141a is formed on the inner surface of the first fixing stand 181. In this case, the first pivoting groove 141a and the first rotation shaft 181a should be formed at a point where the control box 141 can maintain horizontality.

The second fixing stand 182 is fixed to allow the first fixing stand 181 to rotate about one axis. For this purpose, the first fixing stand 181 is formed with a second pivoting groove 181b and a second fixing stand ( A second rotating shaft 182a rotatably engaged with the second pivoting groove 181b is formed on an inner side surface of the 182. In this case, the second pivoting groove 182b and the second rotation shaft 182a should be formed at a point where the first fixing stand 181 can maintain horizontality.

On the other hand, the axis formed by the first rotating groove 141a and the first rotating shaft 181a and the axis formed by the second rotating groove 182b and the second rotating shaft 182a are arranged to be orthogonal to each other, thereby controlling the control box 141. This allows you to rotate in various directions.

Subsequently, on the outer surface of the second fixing stand 182, a connecting bracket 182b is formed to protrude so that the support members 183, 183 ', and 183 "are rotatably fixed, respectively, thereby supporting the supports 183, 183', and 183". The binding body 183a and the hinge stand 183b formed at the upper end thereof are connected to be rotatably engaged. In addition, the connecting bracket 182b is rotatably fixed to the second fixing stand 182, and for this purpose, the connecting bracket 182b has a connecting shaft 182c rotatably inserted into the second fixing stand 182. As a result, the supports 183, 183 ′, and 183 ″ rotate in accordance with the curved state of the ground to allow the geographic information collecting device 100 to be stably placed.

In addition, as shown in Figure 5, when storing the geographic information collecting device 100, the first and second communication modules (110, 120), the flat plate-shaped support (183, 183 ', 183 ") is a sensitive configuration, Wrapping and protecting the reception detection module 130, the lifting device 150, the control module 140 and the GPS module 170, to perform the function of the protective case.

As shown in FIG. 5, the support members 183, 183 ′, and 183 ″ rotatably fixed to the control box 141 may be closely connected to each other when the geographic information collecting device 100 is stored as shown in FIG. 5. It is fixed so that, it consists of a main body 191 having a constant weight, a permanent magnet 192 disposed on the outer surface of the main body 191, and an annular hook 193 protruding on the upper surface.

On the other hand, corresponding to the lower surface of the support (183, 183 ', 183 ") of the magnetic material 183c of the metal material in response to the permanent magnet 192 is attached, between the support (183, 183', 183") It is in close contact with the permanent magnet 192 of the cap 190 is located.

That is, the supports 183, 183 ′, and 183 ″ are firmly fixed to the cap 190.

Subsequently, the cap 190 according to the present invention is utilized for the purpose of applying weight so that the control box 141 is always horizontal.

As described above, the optical signals transmitted and received to the first and second communication modules 110 and 120 always move horizontally. Accordingly, the first and second communication modules 110 and 120 should also be horizontally arranged. However, since the ground surface on which the geographic information collecting device 100 is installed is severely curved according to its position, it is difficult to horizontally arrange the first and second communication modules 110 and 120.

Accordingly, the control box 141 is rotatably fixed to the supporter 180, and the center of gravity is located at a low position of the geographic information collecting device 100. Since the former condition has been described above, repeated description is omitted.

The latter condition is achieved through the cap 190. First, the cap 190 is separated from the geographic information collecting device 100 stored in the state shown in FIG. When the cap 190 is separated, the supports 183, 183 ', and 183 "rotate freely with each other, as shown in FIG. 7 (front view showing another operation of the geographic information collecting device according to the present invention). It is fixed.

In this manner, the hook 193 of the cap 190 is connected to the ring 142 protruding from the bottom of the control box 141. Of course, the main body 191 of the cap 190 should have a sufficient weight to lower the center of gravity of the geographic information collecting device 100.

For reference, the main body 191 may apply a sufficient weight to maintain a horizontal state at all times regardless of the ground state where the geographic information collecting device 100 is placed, and the center of gravity of the geographic information collecting device 100 may be lowered. The weight of the main body 191 is the sum of the weights of the first and second communication modules 110 and 120, the reception detection module 130, the lifting device 150, the control module 140 and the GPS module 170. It is preferable to have the above weight.
