Description

[0001] Inclinometer having a 3D measurement structure [

The present invention relates to an inclinometer having a three-dimensional measuring structure, and more particularly, to a three-dimensional measuring structure for improving the precision in measuring the inclination while improving the structural simplification and installation convenience. Lt; / RTI >

Generally, when building foundation such as an apartment or a high-rise building is to be built, it is necessary to place the building at a predetermined interval (for example, 30 m) at a depth of 50 m / 100 m And a probe connected to the cable along the inclinometer tube embedded therein is inserted to measure whether or not the slope tube which is settled according to the settlement of the surrounding ground is deformed.

Such a probe has a probe which is installed at the end of a cable wrapped around a cable reel and is provided at a predetermined interval (For example, 50 cm), the probe is inserted into the inclinometer tube when the operator manually lowers the cable, so that the depth at which the probe is lifted or lowered can be grasped through the markers.

In addition, the inclination sensor is installed on the probe side, and the tilt value is periodically measured by the inclination sensor due to the settlement of the tilt tube. In the tilt sensor, the inclination value according to the tilt detection of the tilt tube is converted into the analog Voltage signal to the measurement terminal via the ground cable reel via the cable.

The inclinometer 10 for horizontally inclining the surface of the earth is composed of a body 11 having one sensor 12 as shown in Fig. 1, and in order to measure the degree of inclination, a plurality of bodies 11 are connected and / The communication line 13 is taken out from the sensor 12 formed in each body 11 and connected to the external MUX 15 to be collected into a single line and transmitted to the logger 16, .

However, the conventional inclinometer as described above has a problem in that it is measured while raising and lowering from time to time to measure the inclination, and there is a considerable inconvenience, and there is a problem that the incline can not be accurately changed.

Unlike this inclinometer, inclinometers installed at a place where the ground or inclination change is to be measured are programmed to appear in the external monitoring terminal at a tilt angle which is changed in the initial installation state.

In this way, the inclinometers are used in various forms according to their purposes. For this purpose, a protective tube body is formed in the shape of a metal tube, and a short axis or two-axis sensor is fixed inside the protective tube. Such a protective tube has a problem that it requires a large amount of cost because it needs to form a wire and a protective tube so as to tightly seal the inside of the protective tube.

The sensor inserted inside the protective pipe of the metal is connected with the cable and connected with the sensor inside the adjacent metal protective pipe, and the operation is continued to the length of the place to be installed.

In the case of such a sensor, it is necessary to install the sensor in a horizontal state in accordance with the baseline when installing the sensor for the first time, so that the change in the inclination behavior can be detected. In addition, since a sensor is built in the metal pipe to protect it, there is a physical distance as long as the length of the metal pipe. For this reason, the distance between the sensors is narrowed and it is difficult to measure the movement accurately.

Conventional sensors with short axis or two axis sensor inside the metal protection tube are difficult to measure for high displacement parts because the range of inclination change measurement can be measured within ± 10 °.

In addition, when the sensor receives data on the change of the sensor and displays it as a line, only the linear motion can be known based on the point where the sensor is located, and the behavior between the sensors can not be known. That is, since the sensor is embedded in the metal pipe, when the metal pipe itself is installed in a place where the change of the inclination is measured, the change of the installation surface can not be detected by the hard metal pipe.

Also, since the information collected by each sensor is collected from a MUX (MULTIPLEXER) into a single line, transmitted to a logger, and then transmitted to a server through a wireless communication module, a MUX must be separately provided. It is troublesome to connect to the network.

As shown in FIG. 9, the TPMS sensor is installed along the inner wall of the tunnel. Since the inner wall of the tunnel is curved, if straight metal pipes are installed at regular intervals, they are not attached to the curved surface, So that they are spaced apart. In this case, there is an inconvenience in that the effective space must be maintained in the tunnel.

Accordingly, the use of the inclinometer 1 according to the present invention will now be described.

First, in order to measure the vertical inclination due to subsidence of the ground using the inclinometer 1 having the three-dimensional measuring structure of the present invention, the inclined gauge 50 is buried in the ground like a normal measuring method with reference to FIG.

Thereafter, the inclined gauge 50 is inserted into the inclinometer 1 of the present invention, and the body 100 made of a hydraulic hose may be inserted continuously in a lengthwise manner without any additional connection or the like at the time of its insertion.

In order to measure the horizontal inclination due to subsidence or the like of the ground using the inclinometer 1 having the three-dimensional measuring structure according to the present invention, it is necessary to provide a hydraulic hose The body 100 may be continuously arranged along the paper.

The communication line 250 is connected to the logger 300 through a single line, since the communication line 250 is drawn from the connected body 100.

Accordingly, the inclinometer 1 according to the present invention can measure in multiple directions through the three-axis sensor 210, and it is possible to easily install the inclinometer 1 without setting any directionality.

In the inclinometer 1 according to the present invention, the positions of the three-axis sensors 210 of the sensor module 200 formed in the body 100 in the X, Y, and Z-axis directions are set These positions are collected in the logger 300 via the communication line 250, and the collected information is transmitted to the server through the wireless communication module 310.

In addition, the inclinometer 1 installed as described above may set the reference point to zero at a point where the first three-axis sensor 210 is positioned without a separate zero point adjustment.

As described above, the inclinometer 1 according to the present invention can continuously measure the inclination without adjusting the flow in the installed state.

The three-axis sensor 210 of the inclinometer of the present invention can measure the three-dimensional measurement in three directions in the X, Y, and Z directions, thereby enabling accurate measurement in multiple directions.

In addition, the measurement with the inclinometer 1 of the present invention will be able to precisely measure the degree of inclination with respect to a portion corresponding to a portion between the sensor modules 200 where the three-axis sensor 210 is not located , The measurement value thus measured can be recorded in a curved shape as shown in Fig. 8 instead of the linear recording method as in the case of the normal inclinometer in Fig. 7 when recording on the graph, and more precise measurement becomes possible.

In addition, when the inclinometer is installed inside the tunnel 60,

It is not fixed in close contact with the wall surface of the tunnel as shown in FIG. 9 but is installed to be spaced apart from the wall surface of the tunnel due to the body of a straight tube, so that various problems arise and the change of the wall surface of the tunnel can not be recognized immediately. The detection of the inclination of the fixed body 11 is performed.

As a result, only a graph composed of connections of straight lines can be obtained as shown in FIG.

On the other hand, the inclinometer 1 according to the present invention is curved along the inner wall surface of the tunnel and fixed at the same curvature as the wall surface, so that the change of the tunnel wall surface itself can be represented by a curve.

11, it is very easy to measure the inclination by providing it in a curved portion like the inside of the tunnel 60 as shown in Fig. 11, and the measuring state can also be precisely measured as shown in Fig.

As described above, the inclinometer having the three-dimensional measurement structure according to the present invention can be installed in an inclinometer system, and can be installed in a simple arrangement manner without a complicated configuration. By applying a three-axis sensor capable of measuring X, Y and Z directions in the construction, it is possible to accurately measure the vertical inclination of the stratum and the multiple directions of the horizontal inclination of the ground.
