Lightning is a discharge phenomenon that occurs between clouds and the ground. Recently, the frequency of lightning strikes is increasing due to the effects of global warming, and the intensity of the lightning current accompanying lightning is also becoming stronger.

Lightning can cause serious human and material damage. In the past, when lightning rods were not developed, there were incidents where lightning struck a facility storing city gunpowder and many people lost their lives. When a lightning strike occurs, electricity flows not only to the person directly struck by lightning but also to those around them, sometimes resulting in loss of life.

As the dipole lightning protection device 210 and the management server 300 are connected to each other using a communication network, they may be capable of communicating.

In some embodiments, the communications network may be Wi-Fi, the Internet, one or more local area networks, wire area networks, cellular networks, mobile networks, other types of networks, or such networks. It may include a combination of these.

Meanwhile, the lightning monitoring system 100 using a dipole lightning protection device according to an embodiment of the present invention can be applied to an already installed smart pole 200, and the smart pole 200 is used to protect the smart pole 200 from lightning. A dipole lightning protection device 210 may be installed at the top of . Meanwhile, in the present invention, the dipole lightning protection device 210 is shown as being installed on the top of the smart pole 200, but it is not limited to this and can be installed on the top of an object, pillar, building, etc. to protect against lightning. .

Recently, a smart platform applying the latest information and communication technology (ICT) such as the Internet of Things (IoT), Cyber Physical Systems (CPS), and big data solutions has been established to efficiently operate and manage the city's infrastructure. In addition, so-called smart villages, a sub-concept of smart cities that collect and utilize public data to solve various urban problems such as environment, transportation, and energy, and provide citizens with a safe and enriched life, are spreading.

As shown in FIG. 2, the dipole lightning protection device 210 includes a rod member 211 charged with ground charges, and at least two

insulators

212a and 212b installed along the longitudinal direction of the rod member 211. and a charging plate 213 installed between the neighboring

insulators

212a and 212b, electrically insulated from the load member 211, and charged with a polarity opposite to the ground charge; It is installed between the insulators 212b, is electrically connected to the charging plate 213, and is connected to the charging tube 214, which is charged with a charge having a polarity opposite to the ground charge, and the upper end of the rod member 211, thereby causing lightning. It may include a rod cap 215 that induces and a sensor unit 216 that measures vibration generated according to the electrical energy charged to the electrified tube by a thundercloud.

The load member 211 is coupled to the top of the smart pole 200 and stands vertically, and can charge the ground.

In addition, the lower end of the rod member 211 may further include a fixing plate (not shown) that can stably fix the rod member 211. The fixing plate is a flat member with a certain thickness, and a coupling member (not shown) that can be firmly fixed to the smart pole 200 may be formed on the surface.

At least two

insulators

212a and 212b are installed in a spaced apart state along the longitudinal direction of the rod member 211, and are insulators made of ceramic or synthetic resin to insulate the rod member 211 and the charging tube 214. You can. Here, the

insulators

212a and 212b may include a first insulator 212a installed above and a second insulator 212b installed below the electrification pipe 214, and the second insulator 212b An insulating protrusion 214-1 that is inserted into the charging tube 214 may be formed at the top of the . When rainwater flows into the inside of the charging pipe 214 due to the influence of wind, the insulating protrusion 214-1 guides the inflowing rainwater so that it can be easily discharged to the outside of the rod member 211 and at the same time, guides the rainwater into the charging pipe 214. It may have a certain length to ensure sufficient insulation distance between (214) and the rod member (211). The insulating protrusion 214-1 may have a structure in which a plurality of conical members that are narrow at the top and wide at the bottom are continuously connected on the same line.

The charging plate 213 is installed between the

insulators

212a and 212b to maintain electrical insulation from the load member 211 and is electrically connected to the charging tube 214, and has a polarity opposite to the ground charge. It can be. Meanwhile, the charging plate 213 may repeatedly form a wrinkle shape at its circumferential edge. These wrinkles can induce evenly distributed discharge in the circumferential direction of the charging plate 213. This configuration of the charging plate 213 can facilitate discharge between the thundercloud and the ground by concentrating the electric field when lightning strikes.

The charging tube 214 is installed between the charging plate 213 and the insulator (second insulator) 212b, and is electrically connected to the charging plate 213, so that it can be charged with a polarity opposite to the ground charge. The electrification tube 214 is made of a tube shape and can form a hollow center so that the rod member 211 can be coupled thereto.

Meanwhile, the rod cap 215 is installed on the top of the rod member 211 and can induce lightning. The rod cap 215 may be shaped to have a relatively large outer diameter compared to the insulator 212a to greatly improve the lightning inflow area and thereby increase discharge efficiency. That is, the load gap 215 may be formed to be larger than the outer diameter of the first insulator 212a. In this way, if the load cap 215 is formed to be larger than the first insulator 212a, the area for introducing the lightning current increases, thereby allowing the lightning to be discharged quickly.

The electrification tube 214 may be formed in a hollow tube shape so that the rod member 211 can be positioned at the center of the electrification tube 214.

The first sensor unit 216 may include a piezoelectric element sensor that is coupled to the electrified tube 214 and measures vibration generated according to electrical energy charged to the electrified tube 214 by a thundercloud. For example, as shown in the image 270 of FIG. 2B, the piezoelectric element sensor 275 is made of a tube surrounding the charged tube 214, and the charged tube 214 is coupled thereto. A hollow can be formed so that

In addition, the first sensor unit 216 is coupled to a plurality of fastening protrusions protruding outside the electrification tube 214, and receives the vibration of the electrification tube 214 from the electrification tube 214 to the piezoelectric element sensor 275. It may include a receiving part that transmits. In addition, the first sensor unit 216 may include a housing surrounding the receiving portion and the piezoelectric sensor 275 and having a support portion that elastically supports the piezoelectric sensor according to deformation of the piezoelectric sensor 275. there is. In this case, the housing may be made of an insulating material.

In addition, the first sensor unit 216 detects the approach of a thundercloud by detecting the polarity of the charges charged to the charging tube 214 and the rod member 211, and controls the piezoelectric element sensor 275 to output a voltage signal. It may include a detection circuit that does. Since the detection circuit controls a voltage signal to be output from the piezoelectric element sensor 275 when a thundercloud approaches the dipole lightning protection device 210, the voltage signal is not generated for vibration caused by factors other than the approach of a thundercloud. You can control it so that it is not output.

In the dipole lightning protection device 210 according to an embodiment of the present invention, when a thundercloud approaches, the space charge distributed in the atmosphere by the thundercloud is charged to the charging plate 213 and the charging tube 214, and the space charge and The load member 211 is charged with the opposite polarity and supplied from the ground, that is, the ground charge. In this way, as the space charge and the ground charge gradually charge the charging tube 214 and the load member 211, respectively, as the thundercloud approaches, the charging voltage, that is, the charging tube 214 and the load member ( 211) The charging voltage between the liver increases and a discharge (corona discharge) occurs.

At this time, the first sensor unit 216 may measure vibration generated by corona discharge and generate a vibration signal. The first sensor unit 216 may convert the generated vibration signal into a voltage signal.

Additionally, the dipole lightning protection device 210 may include a communication unit 220 and a detection circuit 250. The detection circuit 250 may obtain a voltage signal as analog data, convert the analog data into digital data, and output the digital data as voltage data. The detection circuit 250 may transmit voltage data to the communication unit 220. The communication unit 220 may transmit voltage data to the management server 300.

Meanwhile, although it is explained here that voltage data is transmitted to the management server 300, the dipole lightning protection device 200 may determine the risk of lightning and transmit the determination result to the management server 300. For example, the dipole lightning protection device 200 may further include a control unit (not shown). The control unit (not shown), like the analysis module 320 to be described later, can determine the risk of lightning by analyzing voltage data. Additionally, the control unit (not shown) may transmit the analysis results to the communication unit 220, and the communication unit 220 may transmit the analysis results to the management server 300.

Previously, the size of a thundercloud was analyzed by sensing the amount of light emitted with an optical sensor using a light emitting sensor (LED) that emits light by the induced voltage generated by the lightning protection device as the thundercloud approaches. This existing lightning monitoring system had a problem in that the light emitting sensor was burned out when the induced voltage was large, or the lifespan of the light emitting sensor was shortened depending on the number and size of induced voltage occurrences, causing frequent breakdowns. Additionally, due to replacement of the light emitting sensor, there was a need to change the settings for processing data.

However, the lightning monitoring system according to an embodiment of the present invention measures the vibration generated by a thundercloud through the dipole lightning protection device 210 using the piezoelectric element sensor 216 installed in the electrification tube 214, thereby inducing It is possible to prevent sensor failure depending on the size of the voltage, and has the effect of accurately obtaining data to analyze the size of a thundercloud.

The image 260 of FIG. 2B shows a state in which a plurality of

fastening protrusions

251, 252, 253, and 254 protrude out of the charging tube 214. For example, when the position of the switch 240 is changed from the first position to the second position, the plurality of

Additionally, support

parts

281, 282, 283, and 284 may be provided in the second outer direction of the piezoelectric sensor 275. The second external direction may be opposite to the first external direction. Since the size of the piezoelectric sensor 275 is changed by vibration, the

supports

281, 282, 283, and 284 may have elasticity so that the piezoelectric sensor 275 can be fixed to the charging tube 214. . Additionally, the sensor unit may include a housing 280 that surrounds the piezoelectric sensor 275 and is coupled to the

support units

281, 282, 283, and 284. Housing 280 may be made of an insulating material.

The detection circuit 250 may obtain a voltage signal as analog data, convert the analog data into digital data, and output the digital data as voltage data. The detection circuit 250 may be connected to the heater 260 and the cooling fan 270. The detection circuit 250 may include an analog to digital converter (ADC). The detection circuit 250 may transmit voltage data to the communication unit 220. The communication unit 220 may transmit voltage data to the management server 300. Additionally, the communication unit 220 may transmit voltage data to the control unit of the dipole lightning protection device 210. The control unit can determine the risk of lightning by analyzing voltage data.

Since the components corresponding to the components in the first embodiment of the present invention described with reference to FIG. 2 perform the same or similar functions as those described in the first embodiment, a more detailed description thereof will be omitted.

As shown in FIG. 3, the second sensor unit 416 is electrically connected between the rod member 211 and the charging tube 214 and generates a vibration signal by electrical energy charged to the charging tube 214 by thunderclouds. It may include a first piezoelectric element sensor 416a that generates and a second piezoelectric element sensor 416b that measures the vibration signal generated by the first piezoelectric element sensor 416a and converts the measured vibration signal into a voltage signal. You can. At this time, the first piezoelectric element sensor 416a and the second piezoelectric element sensor 416b may each be formed in a disk shape and combined. The dipole lightning protection device 210 may include a communication unit 220 and a detection circuit 250. The detection circuit 250 may acquire the voltage signal input from the second piezoelectric sensor 416b as analog data and convert the analog data into digital data. The detection circuit 250 may output digital data as voltage data. The communication unit 220 may obtain voltage data from the detection circuit 250 and transmit it to the outside. For example, the communication unit 250 may transmit voltage data to the management server 300.

In the dipole lightning protection device 210 according to an embodiment of the present invention, when a thundercloud approaches, the space charge distributed in the atmosphere by the thundercloud is charged to the charging plate 213 and the charging tube 214, and the space charge and The load member 211 is charged with the opposite polarity and supplied from the ground, that is, the ground charge. In this way, as the space charge and the ground charge gradually charge the charging tube 214 and the rod member 211, respectively, as the thundercloud approaches, a state of electrical contact is maintained with respect to the charging tube 214 and the rod member 211. A vibration signal may be generated from the first piezoelectric element sensor 416a that is maintained.

At this time, the second sensor unit 416 may be installed at a certain height of the smart pole 200 together with the communication unit 220. In this case, the first piezoelectric element sensor 416a may be formed with

terminal pieces

The first piezoelectric element sensor 416a detects the polarity of the electric charge charged to the rod member 211 and the charging tube 214 based on the first terminal piece 417a and the second terminal piece 417b. detects the approach, transmits the vibration signal to the second piezoelectric sensor 416b, and the second piezoelectric sensor 416b can convert the vibration signal into a voltage signal. The detection circuit 250 may acquire the voltage signal input from the second piezoelectric sensor 416b as analog data and convert the analog data into digital data. The detection circuit 250 may output digital data as voltage data and transmit it to the communication unit 220. That is, when a thundercloud approaches the dipole lightning protection device 210, the detection circuit 250 can output voltage data. Additionally, the detection circuit 250 may have the same configuration as shown in FIG. 2B.

On the other hand, if the load member 211 and the charging tube 214 are not charged, the polarity of the charge is not detected through the first terminal piece 417a and the second terminal piece 417b, so there is no approaching thundercloud. It can be judged that

Previously, the size of a thundercloud was analyzed by sensing the amount of light emitted with an optical sensor using a light emitting sensor (LED) that emits light by the induced voltage generated by the lightning protection device as the thundercloud approaches. This existing lightning monitoring system had a problem in that the light emitting sensor was burned out when the induced voltage was large, or the lifespan of the light emitting sensor was shortened depending on the number and size of induced voltage occurrences, causing frequent breakdowns.

However, the lightning monitoring system according to an embodiment of the present invention generates a vibration signal in the first piezoelectric element sensor 416a using the induced voltage generated by a thundercloud through the dipole lightning protection device 210, and the first piezoelectric element sensor 416a 1 By measuring the vibration signal generated by the piezoelectric element sensor 416a by the second piezoelectric element sensor 416b, data for analyzing the size of the thundercloud can be accurately obtained, and the second sensor unit 416 by the external environment ) has the effect of protecting.

The communication module 310 may receive voltage data from the communication unit 220.

The analysis module 320 can determine the lightning risk by analyzing the received voltage data. Specifically, the analysis module 320 may determine the risk of lightning according to the generation cycle and voltage magnitude value of the received voltage data. For example, when the analysis module 320 receives voltage data from the communication unit 220 of the smart pole 200, the analysis module 320 may determine the lightning warning level. In addition, as the caution phase continues (voltage data is continuously received), the analysis module 320 determines whether the occurrence period of voltage data becomes less than a preset boundary reference value or the voltage magnitude increases above the preset boundary reference value.
