In general, a diamond cutting tool such as a wire saw, a core drill, a wheel saw, or the like is used to cut / dismantle a concrete structure. The wire saw method refers to a method of cutting a concrete structure by connecting a wire saw to a structure to be cut, for example, a concrete structure, rotating the driving pulley at high speed, and applying tension to the wire according to the movement of the driving pulley. .

The wire saw method is a low noise, vibration-free method, there is no limitation on the cutting depth or cutting angle of the concrete structure, and does not damage the existing concrete structure. Such a wire saw method may be classified into a wet dismantling method and a dry dismantling method.

The dry dismantling method is an environmentally friendly dismantling method that solves environmental problems such as scattering dust, waste water and sludge generated in the conventional wet dismantling method using water, and is used for partial dismantling of nuclear power plants, hospitals, and apartments. In addition, the dry dismantling method, unlike the conventional cutting / dismantling technique, does not require a complicated cooling device which was absolutely necessary to cool the frictional heat generated during cutting / dismantling. In other words, the dry dismantling method is a method of treating a heat resistant diamond cutting tool that overcomes frictional heat with a cutting device and dust generated during cutting with a dust collecting device having a collecting device.

Also, the term "part" or the like, as described in the specification, means a unit for processing at least one function or operation, and may be implemented by hardware, software, or a combination of hardware and software.

First, a noise source that generates noise includes construction noise, factory noise, sound diffusion, road traffic noise, aircraft noise, railway noise, neighbor noise, and the like according to the embodiment of the present invention. The noise generated by friction between the saw and the concrete structure is generated. If there is a movable structure or a nearby structure near the work site, the noise must be controlled in case of a complaint.

In addition, vibration refers to an undesirably strong vibration, and vibration pollution causes the ground vibrations generated by field work to propagate in the residence, so that residents can feel such vibrations directly and cause sensory complaints due to the sound of window glass shaking. Can be. In particular, when a large vibration is generated by the dry dismantling equipment used in the workplace, there is also physical damage such as cracking or falling objects, such as walls, tiles of the adjacent movable structure.

As an embodiment of the present invention, environmental complaints such as noise / vibration / dust occur when dismantling a part of a building that is currently being used, while installing a wireless sensor at a point where environmental complaints are predicted, and performing dry dismantling. By tracking and managing environmental damage in real time, it automatically provides an alarm signal to dry dismantling equipment in the event of noise / vibration above the environmental standard, and in real-time that reduces cutting efficiency by reducing the tension of the wire saw but does not cause environmental problems. Provided are a control device and method for concrete structure dismantling equipment (eg, for dry dismantling) by monitoring environmental factors.

4 is a view for explaining the principle of the control device for dismantling equipment for concrete structures by real-time environmental factor monitoring according to an embodiment of the present invention, Figure 5 is a concrete structure by real-time environmental factor monitoring according to an embodiment of the present invention It is a block diagram of the control apparatus for dismantling equipment.

4 and 5, the control device for concrete structure dismantling equipment 200 by real-time environmental factor monitoring according to an embodiment of the present invention, the wireless sensor (211, 212, 213), wireless receiver 220, The environmental reference value setting unit 230, the comparison unit 240, the statistical analysis unit 250, the memory 260, the remote control unit 270, the alarm generating unit 280 and the display 290 are included. In addition, the dry dismantling equipment 100 may include, but is not limited to, a wire saw 110, a driving pulley 120, a driving motor 130, a generator 140, a controller 150, and a tension controller 160. In this case, the wire saw 100 may be divided into a cut surface wire 110a and a wire 110b other than the cut surface. Here, the dry dismantling equipment 100 is a general concrete structure dismantling equipment that plays a role of generating vibration, dust, or noise, and thus, detailed descriptions of its components will be omitted.

The wireless sensors 211, 212, and 213 include at least one vibration sensor 211, a dust sensor 212, and a noise sensor 213, and dry dismantling equipment for dismantling or cutting the concrete structure 300 ( Generates a measurement signal by detecting vibration, dust or noise generated by the operation of 100). In this case, the vibration sensor 211 is installed on the movable structure 410 adjacent to the dismantled concrete structure 300, the dust sensor 212 and the noise sensor 213 is a predetermined distance from the dismantled concrete structure 300. It may be installed in the adjacent structure 420 spaced apart.

The wireless receiver 220 wirelessly receives each measurement signal detected from the at least one wireless sensor 211, 212, 213.

The environmental reference value setting unit 230 sets an environmental reference value according to an environmental factor of a work site where the dry dismantling equipment 100 operates. In this case, the environmental reference value setting unit 230 is the environmental reference value according to the distance between the wireless sensor (211, 212, 213) and the dry dismantling equipment 100, and the characteristics of the concrete structure 300 dismantling work site. Can be set variable.

The comparison unit 240 compares each measurement signal received through the wireless receiver 220 with the environmental reference values set by the environmental reference value setting unit 230, respectively.

In this case, the measurement signal, the environmental reference value, and the statistical analysis data are stored in the memory 260. Here, in the case of vibration or noise data, instead of using the data compared in the comparator 240, the statistical analysis data is accumulated by accumulating the data compared by the comparator 240 in the statistical analyzer 250. The reason is that since the vibration or noise data is generated by a complex vibration source or noise source, the average value of the statistically analyzed data, for example, data accumulated according to an analysis algorithm, is compared with a predetermined threshold value. .

The remote controller 270 checks whether the statistical analysis data exceeds a predetermined threshold value, generates a control signal for adjusting the power or tension of the dry dismantling equipment 100, and controls the control unit of the dry dismantling equipment 100 ( 150).

In particular, in the case of a building in which the work site is operating, it may be monitored by environmental standards during operation, or in the case of an operating factory building, it may be monitored for damage of nearby structures and facilities. In other words, the application of dry dismantling equipment to concrete structures such as industrial facilities, office buildings, and hospitals in operation monitors in real time the environmental and structural damages that may occur during dry dismantling. Emphasis is placed on responding to complaints with residents.

On the other hand, Figure 6 is a schematic diagram of the hardware and software of the control device for dismantling equipment for concrete structures by real-time environmental factor monitoring according to an embodiment of the present invention.

Referring to FIG. 6, the control apparatus for concrete structure dismantling equipment by real-time environmental factor monitoring according to an embodiment of the present invention may include hardware such as an A / D board 510, a data logger 520, and a PC 530. It may be implemented in software such as the monitoring program (540).

For example, the wireless sensor 210 may be a vibration sensor 211, dust sensor 212 or noise sensor 213, the analog signal sensed by this wireless sensor 210 is the A / D board 510 Is converted into a digital signal, transmitted to a PC 530, for example, a portable notebook computer via the data logger 520, and analyzed by the monitoring program 540, and then power / tension adjustment. You can generate a signal.

Here, the data logger 520 is currently used in many fields such as an observation system, a metering system, and an environment and an industrial facility management system together with an automation system. The data logger 520 is a wireless sensor (real time) from a short-range or long-range system in real time. The vibration, dust or noise data is obtained from 210. For example, as the work area expands, field data can be acquired in real time or at regular intervals in a system that has a large data area to collect. Therefore, by using the data logger 520 according to an embodiment of the present invention to monitor the state of the wireless communication equipment or system in real time, it is possible to increase the stability and efficiency of the control device for concrete structure dismantling equipment.

On the other hand, Figure 7 is a diagram illustrating a comparison of the measurement data and the environmental reference value of the noise sensor according to an embodiment of the present invention.

In the case of dry dismantling equipment 100, the noise level around the wire saw and dust collector is high. If the distance between the work site where the dry dismantling equipment 100 is installed and the noise sensor is changed, the environmental standard value is different. As shown in FIG. 7, the environmental reference value according to an embodiment of the present invention may be set to 88 dB. For example, 60 times per minute may be measured and compared with the environmental reference value, and statistical analysis data may be set to a preset threshold. If exceeded, it is determined that the power or tension of the dry dismantling equipment 100 is excessive, and after generating a power / tension control signal to reduce excessive power or tension, the power or tension of the dry dismantling equipment 100 is adjusted. Done.

In FIG. 7, an environmental reference value is set for noise, but environmental reference values may be set for vibration and dust, respectively.

For example, the vibration generated when the dry dismantling method of the concrete structure 300 is applied is measured for each distance along the path of vibration propagation from the dry dismantling device 100 and the accessory equipment as the vibration source, and if the frequency analysis, The vibration generated in the dismantling method of the structure 300 is mainly 60 ㎐ component generated from equipment such as a generator and a compressor. In practice, the maximum amount of vibration generated during the dry dismantling operation is 0.256 ~ 0.356 mm / sec for each measurement position, and the 60 kHz component mainly generated in the field generator becomes the main vibration source, and the influence of the accessory equipment such as the compressor As a component other than 60 Hz can be expressed.

In addition, the dust is fine dust generated from the concrete structure 300 according to the operation of the dry dismantling equipment 100, can be measured by comparing before and after the operation of the dry dismantling equipment 100.

On the other hand, the control device and method for concrete structure dismantling equipment by real-time environmental factor monitoring according to an embodiment of the present invention, can be implemented using a ubiquitous sensor network (USN), wherein, the ubiquitous sensor network ( USN) refers to a network that attaches a wireless communication module to all things to connect to a network such as the Internet to recognize and manage information.

Using this USN technology, a wireless sensor with a network module is installed in a noise regulation area or a vibration bundle area that needs to be measured, and a wireless network with autonomous configuration function between wireless sensors is measured and wirelessly measured without a power line connection. By delivering the data over an area of hundreds of meters in radius, it is possible to service workers in real time with noise and vibration and create an environment that is easy to monitor and manage.

This USN technology can provide a variety of environmental information for a relatively small cost over a large area, for example, if the noise and vibration only occurs during a limited time period, such as construction site, for example, By installing sensors, constructing a wireless sensor network, and supervising the construction during the construction period, the wireless sensors can be collected and recycled or disposed of after the construction is completed.

8 is a schematic configuration diagram of a noise sensor including a short range wireless communication module according to an embodiment of the present invention, and FIG. 9 is a diagram illustrating a configuration of a short range wireless communication module shown in FIG. 8.

Referring to FIG. 8, a noise sensor 213 having a short range wireless communication module according to an embodiment of the present invention includes a noise sensing element 213-1 for detecting noise caused by the operation of the dry dismantling equipment, and the noise detection. An amplifier 213-2 for amplifying the signal sensed by the element 213-1, and a short range wireless communication module 213-3 for transmitting the amplified measurement signal to the wireless receiver 220. .

The short range wireless communication module 213-3 may be selected from, for example, Zigbee, Bluetooth, and ultra-wideband (UWB), but may be any case capable of wireless communication at a short range. In the embodiment of the present invention, an example in which the short range wireless communication module 213-3 is implemented through Zigbee will be described.

The short range wireless communication module according to the embodiment of the present invention may be implemented as a Zigbee module 213-3, as shown in FIG. 9, wherein the Zigbee module 213-3 is a wireless antenna. It may be configured to include an RF receiver, a phase locked loop (PLL), a power control circuit, an RF transmitter, a MAC processor, and a module controller.

Specifically, the RF receiver, the RF transmitter, the phase synchronization circuit, and the power control circuit are components that process operations corresponding to the PHY layer of the Zigbee protocol stack, and determine the RF communication structure and network topology.

The RF receiver and the RF transmitter include an amplifier, a filter, and the like to process frequency signals of a corresponding band. The phase synchronization circuit provides a reference frequency signal so that the RF receiver and the RF transmitter synthesize an intermediate frequency signal. It determines the strength of the received signal to adjust the amount of transmission power. In this case, the IEEE 802.15.4 standard defines two types of PHY layers (2.4G㎐, 866 / 915M㎐), 16 channels in the 2.4G㎐ band, 10 channels in the 902M㎐ to 928M㎐ band, and 868M㎐ to 870M One channel is allocated to the band.

The RF receiver and the RF transmitter use DSSS (Direct Sequence Spread Spectrum), and in the 2.4G 2.4 band, an O-QPSK (Offset-Quadrature Phase-Shift Keying) modulation scheme of 32 PN code length is used, and 1 G㎐ In the following band, a Binary Phase-Shift Keying (BPSK) modulation scheme of 15 PN code length may be used, but is not limited thereto.

When the analog signal is processed as described above, the RF receiver and the RF transmitter process the digital signal in the baseband region. In the case of the RF receiver, the digital signal is processed in synchronization, despreading, demodulation, and digital filtering. In the RF transmitter, spreading, signal shaping, and the like are processed. In this case, when the BPSK modulation scheme is used, the baseband processing paths configured by the RF receiver and the RF transmitter may be integrated into one.

When the digital processing of the PHY layer is completed, the MAC (Media Access Controller) processing unit analyzes the transmitted data frame structure to approve the frame and detects an error (detection via CRC or checksum) to determine whether to retransmit. It handles packet routing.

That is, the MAC processing unit is an element for processing an initial hardware network connection, and provides an additional frame structure related to a beacon for time synchronization and a guaranteed time slot (GTS), which enables collision / delay prevention. Channel access is handled by a carrier sense multiple access with collision avoidance (CSMA-CA) method.

The module controller may perform a function of the remaining MAC layer, a network layer, and a framework layer to configure a network topology, and perform a function of an application layer to transmit predetermined data.

Next, the wireless sensor measures the vibration, noise or dust in real time (S130), and then the measurement signal from the at least one wireless sensor for measuring in real time the vibration, noise or dust generated by the operation of the dry dismantling equipment Receive each wirelessly (S140).

Next, the wirelessly received measurement signal is converted into a digital signal, and the measurement signal converted into the digital signal is compared with the predetermined environmental reference value (S150).

Next, the comparison data is statistically analyzed according to an analysis algorithm (S160), and if the analysis data exceeds a preset threshold (S170), when the analysis data exceeds a preset threshold, an alarm signal is generated. Occurs and stops the operation of the dry dismantling equipment (S180).

Next, the power or tension of the dry dismantling equipment is adjusted according to the size of the power or tension control signal (S190).
