Description

Rock-Falling Sensing System Using Data-logger

The present invention relates to a rockfall measurement system using a data logger to install a measuring instrument in a place where a rockfall is concerned, and record the measurement result to prevent rockfall.

Rockfall and landslides are likely to occur in the sea ice. Therefore, it is necessary to scientifically and systematically manage changes in rock joints to prevent accidents by proactively recognizing falling rocks in steep slopes and natural slopes.

Conventionally, a method of detecting a movement of a joint through a change in the length of the wire is installed by installing the wire in a section where the joint is concerned. However, this method has a problem in that reliability decreases as the wire becomes loose over time. In addition, there was room for errors due to damaged or damaged wires for animals or other falling rocks.

In addition, a method has been applied in which a measuring instrument is installed in a cracked area, and a staff member regularly visits the measuring instrument to visually observe the measuring instrument or use an electric tester. However, this method has difficulty in predicting rockfall through real-time observation, making prediction of rockfall difficult, and data reliability is low.

The present invention has been devised to solve the above-described problems, and uses a data logger that can manage changes in rock joints in a scientific way so as to be able to recognize rockfalls occurring in a steep slope and a natural slope in advance. It aims to provide a rockfall measurement system.

In addition, an object of the present invention is to provide a rockfall measurement system that is easy to manage safety by transmitting data measured using a crack meter and an inclinometer using a data logger.

It is also an object of the present invention to provide a method of installing and constructing a rockfall measurement system that is convenient to install and construct on site, and can easily acquire data even if a communication network is lost.

The access port 45 may provide a path for a person to access and download measurement data stored in the data logger 40 to a manual measurement terminal 52 connected to the access port 45.

The communication module 46 may wirelessly transmit measurement data stored in the data logger 40 to the automated measurement server 50 provided at a remote location.

In addition, the present invention is a method for constructing a rockfall measurement system using the data logger, the step of selecting a rock crack, and removing the moisture of the crack system 20 and the inclinometer 30 to be installed; Using a setting band, epoxy or anchor bolt, fix the first attachment part 23-1 of the sensor body 21 to the base part 11 facing the rockfall concern part 12, and setting band, epoxy Or using the anchor bolt to install the crack system 20 for fixing the second attachment portion 23-2 of the tip 22 to the rockfall concern 12; An inclinometer 30 installation step of fixing the third attachment portion 33 of the main body 31 to the rockfall concern portion 12 by using a setting band, epoxy or anchor bolt on the rockfall concern portion 12; Connecting the cables 24 and 34 to the installed crack system 20 and the inclinometer 30, respectively; Selecting a location that is close to the installed crack system 20 and inclinometer 30 and accessible to a person, and removing moisture at a portion where the data logger 40 is to be installed; Fixing the housing 41 to a positioning unit using a setting band, epoxy or anchor bolt; Electrically connecting the cables (24, 34) connected to the crack meter (20) and the inclinometer (30) to the substrate (42); And installing the solar panel (44) in a location where direct sunlight is lifted, and electrically connecting the solar panel and the battery with a cable.

The rockfall measurement system of the present invention can be easily constructed even in areas where installation is difficult.

In the rockfall measurement system of the embodiment according to the present invention, when a rock joint 13 is generated as shown in FIG. 3, when the rockfall concern 12 occurs from the base 11 of the rock 10, the joint 13 The crack meter 20 is installed in the vicinity of the crack, the inclination meter 30 is installed on the rockfall concern 12, and the data measured and accumulated by the crack meter 20 and the inclinometer 30 can be stored. The logger 40 is installed in the vicinity of the crack system 20 and the inclinometer 30. The data logger 40 is located close to the crack meter 20 and the inclinometer 30, but is installed at a location that can be easily accessed by a person.

The crack meter 20 and the inclinometer 30 may be connected to the data logger 40 by cables 24 and 34, respectively. The cables 24 and 34 have different colors of the sheaths so that it is easy to determine which cable is connected to which instrument (crack or inclinometer), so that when the cable is connected to the data logger 40, the cable is easily distinguished. It can be done, and maintenance can be done conveniently.

If the cable is stretched by its own weight, it can affect the measured value of the instrument, so the cable can be fixed at a predetermined distance to the rock wall. The cable can be fixed with an adhesive such as epoxy to minimize damage to the rock wall. In addition, there is a fear that rainwater may descend on a cable and infiltrate or affect an electrical connection portion of the data logger 40 or the instruments 20 and 30. Accordingly, the cable section of the vicinity connected to the data logger 40 and the measuring instruments 20 and 30 is fixed to be downward at a predetermined section, thereby preventing infiltration of rainwater.

Referring to Figure 1, the crack meter 20 is provided with a sensor body 21 and the tip 22. The sensor body 21 and the tip 22 may be respectively fixed to both sides with a crack or joint 13 interposed therebetween. To fix the arm wall, the sensor body 21 and the tip 22 are provided with a first attachment portion 23-1 and a second attachment portion 23-2, respectively.

The sensor body 21 may be a joint-meta-type electric sensor. The electric sensor has a resolution of 0.003 mm or less, which makes it possible to measure very precisely. In addition, the electric sensor can operate normally in the range of 30 degrees Celsius to 80 degrees Celsius, and can be operated normally even in winter. In particular, it is desirable to be able to operate normally even in a low temperature environment in order to prepare for joint and rockfall problems occurring in the thawing period. On the other hand, since the crack displacement of the joint is made very finely, in consideration of economical efficiency, the measurement range of the crack meter 20 is sufficient to be about 50 mm maximum.

The sensor body 21 is installed on the base 11 of the rock 10 through the first attachment portion 23-1. And the tip 22 is installed on the rockfall concern 12 adjacent to the base 11 through the second attachment portion 23-2.

Referring to FIG. 1, the inclinometer 30 includes a main body 31 and a third attachment portion 33 for fixing the main body 31. The main body 31 may be installed on the rockfall concern 12 through the third attachment portion 33.

The inclinometer has a high sensitivity (MEMS) sensor. The resolution of the high-sensitivity sensor is 0.001785714 (Degree / Volt), which enables very precise measurements. In addition, the high-sensitivity sensor can operate normally in the range of minus 20 degrees Celsius to 50 degrees Celsius, so it can be operated normally even in winter. In particular, it is desirable to be able to operate normally even in a low temperature environment in order to prepare for joint and rockfall problems occurring in the thawing period. On the other hand, since the crack displacement of the joint is made very finely, in consideration of economical efficiency, the measuring range of the inclinometer 30 is sufficient to be about -5 degrees to 5 degrees.

The inclinometer 30 can measure the displacement of two or more axes of the rockfall concern. Therefore, when the inclinometer 30 is attached to the surface of the rockfall concern 12, it is possible to continuously measure and calculate the displacement of the inclination angle based on the initial attachment point.

Since the power supply to the crack meter 20 and the inclinometer 30 can be made from the data logger 40 by the cables 24 and 34, there is no need to install separate power sources to the instrument. In addition, the measurement result may also be transmitted to the data logger 40 through the cables 24 and 34. Therefore, the crack meter 20 and the inclinometer 30 may be provided with only the components necessary for measurement, except for the measurement object and the part to be fixed, and thus the volume can be reduced. This has the advantage that the instrument can be easily installed even in areas where the instrument installation location is difficult.

Since the measuring instrument needs to be measured only once periodically, energy consumption can be reduced. For example, if the measurement is performed once per hour, power consumption can be minimized by applying an RTC circuit to the data logger 40 and operating a sleep mode that minimizes power supply outside the measurement time period. .

2, the data logger 40 is connected to the crack meter 20 and the inclinometer 30 by cables 24 and 34, respectively, and is measured by the crack meter 20 and the inclinometer 30. It has a substrate 42 for storing the data. The substrate 42 may be integrated into one sheet or divided into several sheets.

The substrate 42 may be electrically connected to the measuring devices 20 and 30 to receive a result value measured by the measuring device as an electrical signal. The substrate 42 may be connected to a storage device such as a memory capable of storing the measurement data. The memory may be mounted on the substrate 42. Alternatively, the memory may be externally installed separately from the substrate 42.

In addition, the substrate 42 may supply power to the measuring instruments 20 and 30 through the cables 24 and 34.

The data logger 40 may include a battery 43 that supplies power to the substrate 42, the crack meter 20, and the inclinometer 30. The substrate 42 may receive power from the battery 43 and supply a portion of the power to the instrument.

The data logger 40 may include an enclosure 41 accommodating the substrate 42 and the battery 43. The housing 41, as shown in Figures 2 and 3, is provided with a cabinet that is closed at the rear and up and down, left and right sides, and is opened to the front, and a door that is hingedly coupled to the side of the cabinet to swing open and close. The cables 24 and 34 may be connected to a substrate 42 provided inside the enclosure 41 through a through hole provided at a side of the cabinet. The data logger 40 may be installed above the measuring instrument or may be installed below the measuring instrument. Therefore, it is preferable that the through holes of the cabinet through which the cables 24 and 34 are penetrated are formed on the side surfaces reflecting various installation environments. When the through hole is formed at the top of the cabinet, there is a high possibility of rain or the like permeating, and when the data logger is installed above the instrument, cable wiring is cumbersome. Also, if through holes are formed in the lower part of the cabinet, cable wiring is cumbersome when the data logger is installed below the instrument. On the other hand, if there is a through hole on the side, it is easy to prevent rainwater from entering, but it is possible to conveniently perform all cable wiring regardless of the relative installation position of the data logger to the instrument.

In addition, the data logger 40 has a solar panel 44 disposed outside the enclosure 41 to harvest energy for charging the battery 43.

The solar panel 44 is preferably installed in a place where the sun is well exposed. The enclosure 41 may be installed at a location easily accessible by a person, and if the place where the enclosure 41 is installed is a place where the sun is easily exposed, the solar panel 44 is as illustrated in FIG. 3. It may be installed attached to the housing 41.

When the solar panel 44 is attached to the door of the enclosure 41, the solar panel 44 may be connected to the substrate 42 through a through hole provided in the door. When the solar panel 44 is attached to the enclosure 41 in this way, the process of fixing a separate bracket for mounting the solar panel 44 on a rock or the like can be omitted, and installation is more convenient.

Referring to FIG. 4, the data logger 40 further includes a connection port 45 that is electrically connected to the substrate 42. The connection port 45 is a path through which the system operator can download the measurement data accumulated in the data logger 40 at a time using the manual measurement terminal 52. The access port 45 may provide a path for a person to access and download measurement data stored in the data logger 40 to a manual measurement terminal 52 connected to the access port 45. For this reason, it is preferable that the data logger 40 is installed at a location easily accessible by a person. The connection port 45 may be a USB port. In order to prevent the inflow of rainwater, the USB port may be installed inside the enclosure. When the USB port is installed to be exposed to the outside of the enclosure, a rubber stopper or the like can be installed to prevent rainwater from entering the USB port.

The passive measurement terminal 52 may be, for example, a smartphone or a laptop. The passive measurement terminal 52 may process data downloaded from the data logger 40 and schematically represent changes in cracks and inclination angles over time as shown in FIGS. 5 and 6.

Meanwhile, the data logger 40 includes a communication module 46 that is electrically connected to the substrate 42 of the data logger 40. The communication module 46 may transmit measurement data stored in the data logger 40 to the automated measurement server 50 through long-distance wireless communication such as CDMA, LTE, and 5G.

The automated measurement server 50, the measurement data stored in the plurality of data loggers 40, from the communication modules 46 of the data loggers respectively connected to a plurality of instruments installed at different distances and the different rocking concerns are installed. Each can be received wirelessly. The wireless transmission / reception may be periodically performed once a day. In addition, as shown in FIG. 7, these data may be displayed by being tabulated on a display so that they can be grasped clearly by location. Therefore, the automated measurement server 50 can immediately and systematically manage joint sites of high-risk groups.

Data of the instrument installed at the site that has not received data from the automated measurement server 50 due to a communication network disconnection, etc., and the data of the instrument installed at the site where the communication network does not automatically connect with the automated measurement server 50 The operator can access the data logger 40 on site and download and collect measurement data through the access port 45. If the method of inspecting the joint site by directly visiting a conventional site was a method of measuring an instrument installed at the site with an electric tester, the site inspection method according to the present invention simply downloads the data that has already been regularly and periodically measured and stored. The difference is great in the way it is received. That is, the operator can visit the site about once a month and immediately check the crack change in the meantime.

The method of constructing a rockfall measurement system using the data logger is as follows.

First, a high-risk group of rock cracks is selected, and the crack system 20 and the inclinometer 30 are installed to remove moisture.

Next, using a setting band, epoxy or anchor bolt, fix the first attachment portion 23-1 of the sensor body 21 to the base portion 11 facing the rockfall concern portion 12, and similarly setting it. Using a band, epoxy or anchor bolt, the second attachment portion 23-2 of the tip 22 is fixed to the rockfall concern 12 to install a cracking system 20. It is desirable to apply this in the field where the setting band and epoxy can be applied. The use of anchor bolts may be desirable in that they do not apply in the field where the perforation will affect cracking or jointing, since the rock must be perforated.

In addition, the inclination meter 30 is installed by fixing the third attachment portion 33 of the main body 31 to the rockfall concern 12 using a setting band, epoxy or anchor bolt to the rockfall concern 12. .

Then, the cables 24 and 34 are connected to the installed crack system 20 and the inclinometer 30, respectively.

Next, the crack meter 20 and the inclinometer 30 are installed or close to a location to be installed, and a location accessible to a person is selected as a location for installing the data logger 40.

Then, moisture is removed from a portion where the data logger 40 is to be installed at a selected location. Subsequently, the housing 41 is fixed to the positioning unit using a setting band, epoxy or anchor bolt.

Then, the cables 24 and 34 to be connected to or connected to the crack system 20 and the inclinometer 30 are electrically connected to the substrate 42.

In addition, the solar panel 44 is installed at a location where direct sunlight is exposed, and the solar panel and the battery are electrically connected with a cable. The cable can be connected to the substrate. The substrate may rectify the electromotive force generated in the solar panel to charge the battery.

When the instrument and the data logger are installed in one location of the high-risk group, the operation of interworking with the automated measurement server 50 is performed.

According to the above-described rockfall measurement system, the rockfall measurement system can be conveniently installed in the field, and data is accumulated in the field using a data logger, so that it can be integrated and managed from a remote location through a wireless communication network. Even if it is lost, the data logger is installed in a location that can be easily accessed by the administrator, so data can be secured by simply downloading the accumulated data through the data logger, especially when installed in deep mountainous areas where the communication network is poor. Since the logger accumulates measurement data periodically, management reliability can be improved.

In addition, since the above-described rockfall measurement system periodically measures and secures measurement data, it is possible to minimize the energy consumption rate by applying a sleep mode or the like. In addition, when a solar panel is installed, electric energy for operating a rockfall measurement system without external power can be self-sufficient.

As described above, the present invention has been described with reference to the exemplified drawings, but the present invention is not limited by the examples and drawings disclosed in the present specification, and can be varied by those skilled in the art within the scope of the technical idea of the present invention. It is obvious that modifications can be made. In addition, although the operation and effect according to the configuration of the present invention has not been explicitly described while explaining the embodiments of the present invention, it is natural that the predictable effect by the configuration should also be recognized.
