Description

Building tilt monitoring system {BUIDING SLOPE MONITORING SYSTEM}

The present invention relates to a building inclination monitoring system, and more particularly, to a building inclination monitoring system capable of continuously measuring the inclination of a building from when the frame of the building is constructed to after completion of the construction.

Currently, the method of measuring the inclination of a building in the safety diagnosis of a building is a method of measuring the inclination of a building at the time of inspection after the building is built. Since it cannot be measured, questions are being raised as to whether it is effective in diagnosing the safety of building tilt.

Accordingly, there is a need for an automatic building tilt diagnosis system that can continuously monitor the tilt of a building from the time of construction in conjunction with the automatic building control system.

More specifically, among the current building safety diagnosis methods for measuring the inclination of a building, there is a method for diagnosing the inclination using a MEMS sensor, which is a digital sensor. way.

However, the method using the MEMS sensor has the following problems.

Looking at these problems, first, the conventional MEMS sensor for measuring inclination is an integral operation method using a gyro sensor, which is suitable for measuring dynamic motion such as a rapid change in inclination, but is not suitable for measuring static inclination such as a building. There is a typical problem in that the calculation value diverges due to the accumulation of integration operations and errors also occur due to noise.

The second problem is that conventional MEMS sensors have resolution capable of measuring even minute vibrations. However, since the MEMS sensor that measures even minute vibrations like this reacts to vibrations generated around the building, it is difficult to extract valid data values because other types of data other than the slope value are detected.

1 is a cross-sectional view of a building tilt monitoring system according to an embodiment of the present invention. FIG. 2 is a cross-sectional view taken along line A-A of the building tilt monitoring system shown in FIG. 1 .

1 and 2, the building tilt monitoring system according to an embodiment of the present invention includes a building displacement measurement unit 10, a tilt information conversion unit 20, and a building central monitoring unit 30. .

The building displacement measurement unit 10 is a device for measuring displacement data in a plane direction perpendicular to gravity for measuring the inclination of a building in conjunction with a building. In this embodiment, the building displacement measurement unit 10 is a case 11 ), a wire 12, a weight 13, and a displacement sensor 14, and may further include an oil 15 and a tilt adjustment unit 16.

The case 11 is formed with a hollow inside. In the case of this embodiment, the case 11 is further configured with a cylindrical body 11a having an open top and a lid portion 11b coupled to the upper opening of the cylindrical body 11a to seal the cylindrical body 11a. Here, a ring portion to which the wire 12 is connected is further formed under the cover portion 11b, and the cover portion 11b is separated from the cylindrical body 11a as needed during initial assembly or inspection. The case 11 serves to provide an area where the wire 12 is to be coupled, and seals the wire 12, the weight 13, and the displacement sensor 14 to the outside to prevent the wire 12 and the wire 12 from foreign matter. It serves to protect the weight 13 displacement sensor 14.

The top of the wire 12 is connected to the top of the inner surface of the case 11 . In the case of this embodiment, the wire 12 has an upper end coupled to the cover portion 11b of the case 11, and a lower end coupled to a weight 13. Here, since the length of the wire 12 increases as the length of the wire 12 increases, the resolution for the slope of the building is not limited to the ratio shown in the drawing and is set to various lengths according to the type of resolution.

The weight 13 is accommodated inside the case 11 and is connected to the lower portion of the wire 12 and is stretched in the direction of gravity. The weight 13 is formed as a cylindrical weight and inclines at a certain inclination according to the inclination angle of the building by gravity, thereby forming an inclination corresponding to the inclination of the building. In the case of this embodiment, the weight 13 is formed of a metal material containing a steel material. In addition, when the displacement sensor 14 is composed of an eddy current sensor, the weight 13 includes a plurality of metal material parts 13a in which predetermined regions corresponding to each of the eddy current sensors are formed of a metal material, and the metal material part ( 13a) may be configured to include a non-metallic material portion 13b coupled to the metal material portion 13a. Here, the number of metal parts 13a corresponding to the number of displacement sensors 14 is configured. Therefore, the metal material part 13a is isolated by the non-metal material part 13b when the displacement sensor 14 is configured as an eddy current sensor and the metal material part 13a is magnetized by the eddy current sensor, thereby generating different eddy currents. The magnetization of the sensor minimizes the effect on the detected data.

The displacement sensor 14 is installed around the case 11 to measure the side distance of the weight 13, but consists of a plurality of them to measure the distance of the weight 13 in all directions. In the case of this embodiment, the displacement sensor 14 is composed of an eddy current sensor, and may be composed of a laser displacement sensor or a capacitive displacement sensor, if necessary. In addition, in the case of the present embodiment, the displacement sensor 14 is composed of at least four or more eddy current-type displacement sensors 14 and is coupled to each of the positions dividing the outer circumference of the case 11 into quarters, so that the outer circumference of the weight 13 The distance to each of the positions dividing the periphery into quarters is measured. Therefore, since the displacement sensor 14 can detect the position of the weight 13 by continuously measuring the distance from the weight 13 in four directions, the central position of the weight 13 on the plane based on gravity to measure where it is. Such a displacement sensor 14 measures the distance between the weights 13 to calculate the inclination of the building. More specifically, the position of the displacement sensor 14 for measuring the weights 13 and When the distance between the top ends of the wire 12 is "L" and the moving distance of the weight 13 is "D", the measured tilt angle may be configured as D/L. In this embodiment, the number of displacement sensors 14 has been exemplified and described as four, but it goes without saying that the number of displacement sensors 14 can be increased.

Oil 15 is accommodated inside the case 11 . In this embodiment, the oil 15 may be composed of a viscous oil such as silicone oil 15. Such oil 15 protects the weight 13 and the wire 12 from corrosion, and in particular, when the weight 13 is shaken due to vibration or a large shock from the outside, the weight 13 It serves to attenuate the width of displacement so as not to shake greatly and to quickly return to the original position after the weight 13 is shaken.

The tilt adjusting unit 16 is coupled between the lower part of the case 11 and the building to adjust the tilt. In the case of the present embodiment, the tilt adjustment unit 16 is coupled to the lower fixing plate 16a coupled to the building by anchor bolts or concrete pouring, the lower part of the case 11 and the upper fixing plate spaced apart from the lower fixing plate 16a by a certain distance ( 16b), the bolt body portion 16c formed on the upper fixing plate 16b in a state of being coupled to the lower fixing plate 16a and disposed through the bolt hole, the bolt body portion 16c and A lower nut portion 16d that is screwed together and disposed below the upper fixing plate 16b to support the lower portion of the upper fixing plate 16b and change the position of the upper fixing plate 16b while supporting the upper fixing plate 16b when it rotates. ) and an upper nut portion 16e screwed to the bolt body 16c and pressing the upper portion of the upper fixing plate 16b to fix the upper fixing plate 16b. When the first building displacement measuring unit 10 is installed in a building, the tilt adjusting unit 16 sets a zero point so that the values measured by all displacement sensors 14 of the building displacement measuring unit 10 form the same value. will play a regulating role.

The tilt information conversion unit 20 continuously receives displacement data in conjunction with the building displacement measuring unit 10 . In this case, the gradient information conversion unit 20 includes a digital signal processing unit that converts displacement data, which is an analog signal input from the building displacement measurement unit 10, into digital displacement data by digital signal processing, and a digital signal input from the digital signal processing unit. It includes a tilt information conversion unit that converts the displacement data into building tilt information.

The building central monitoring unit 30 interlocks with the tilt information conversion unit 20 to continuously record and monitor building tilt information, and generates an inspection signal when the building tilt exceeds a predetermined risk level value. Therefore, the manager can know that the slope of the building is at a dangerous level, and can proceed with inspection and repair according to the management guidelines. In addition, the building central monitoring unit 30 is installed in the building to automatically control the facilities in the building in conjunction with systems such as security, heating and cooling facilities, water supply facilities, energy facilities, and ventilation facilities in the building, and the facilities in the building are abnormal. The case of driving is detected and notified to the manager.

Next, the operator adjusts the inclination of the upper fixing plate 16b by rotating the lower nut parts 16d in a state where the upper fixing plate 16b is seated on the lower nut part 16d, so that the value measured by the displacement sensors 14 is Adjusting the inclination of the upper fixing plate 16b to be in the same state and coupling the upper nut portion 16e to the bolt body portion 16c completes the installation work.

In this state, when the slope of the building is slightly inclined, the weight 13 is slightly inclined in the same direction as the direction in which the building is inclined, and the displacement sensor 14 measures the distance value with the weight 13. is continuously measured and the measured value is transmitted to the gradient information conversion unit 20.

In this way, looking at the center position of the weight 13 on a plane when the weight 13 is inclined due to the slight inclination of the building, as shown in FIGS. 3 and 4, the weight 13 ) is changed, and at this time, the four displacement sensors 14 measure the distance to the weight 13 in the four directions shown in the drawing, and the distance of the weight 13 through the distance in each of the four directions. By estimating the center of gravity, it is possible to secure displacement data on how much and in which direction it has moved.

After that, it is converted into a slope value.

In this case, as shown in FIG. 3, the slope value calculated by the slope information conversion unit 20 refers to the distance between the upper ends of the displacement sensor 14 and the wire 12 as "L", and When the distance moved is "D", it is calculated as D/L, and if necessary, an operation of multiplying or adding a variable is set to set a more accurate gradient value. In this case, the slope value can be calculated by the radiance method.
