Description

Alarm device with non-directional vibration detection function and vibration analysis function, and handrail including the same}

The present invention relates to an alarm device having an omni-directional vibration detection function and a vibration analysis function, and a handrail including the same, and in more detail, it is referred to as "X, Y, Z 3-axis" or "360° omnidirectional" or "3D". In the so-called directional premise, the amount of fine change in physical kinetic energy (vibration/shake, acceleration, fall/rise, rotation, movement, stop, etc.) reflected by the acceleration of gravity in that direction is received as a digital signal through a high-sensitivity vibration detection sensor. At the same time, it receives as an analog signal through a piezoceramic piezoelectric sensor composed of a vibration transmission medium and a piezoelectric element, and detects the presence and absence of a vibration detection signal due to shock or earthquake, and the period, continuity, time and time of occurrence, and vibration. Detection of the frequency of the detection signal and the presence or absence of microscopic vibration, the amount of change (value, data) and setting threshold of the vibration detection signal, the comparison reference value, the calculation of the limit values, comparison, temporary storage of information, erasing temporary memory information, etc. Based on the result of computer processing, the intensity of vibration and the type of vibration are automatically detected to accurately identify natural and artificial earthquakes, and corresponding warnings or evacuation signals are audibly or visually recognized by unspecified persons. It relates to an alarm device having an omni-directional vibration detection function and a vibration analysis function, invented to minimize various disasters that may occur due to an earthquake by providing sound or legal standard signals, and a railing including the same.

In general, an earthquake refers to a wave caused by a sudden change in the earth's earth's crust, that is, a seismic wave that is transmitted to the earth's surface and shakes the ground. Scientifically, "the Earth's ground caused by the propagation of seismic waves from an elastic energy source. Can be defined as "vibration".

At this time, the magnitude of the earthquake varies from a very small earthquake that is detected only by a sensitive seismometer to a large earthquake that causes great damage to a wide area, and the magnitude of the earthquake is'Richter scale','Modified Mercully intensity (MMI) scale', Earthquake grades are classified based on the'Japan Meteorological Agency's Scale Classification (JMI)', and various standards and regulations are covered in various public sources regarding the strength (intensity) of earthquakes. "Maximum acceleration: [%g]= 9.81[cm/sec ² " or "gravity acceleration: 1[g]=980[cm/sec ² ", etc."

In addition, to introduce some overviews of earthquakes, the seismic waves propagating along the inside or surface of the Earth, which is an elastic body from the epicenter of the destruction of the rock, are called seismic waves, and the waveform recorded in a normal seismometer is the medium generated by the seismic wave passing through. Is due to the transformation of

The seismic waves are classified as follows according to propagation characteristics.

Body waves are classified into P waves and S waves. At this time, P waves are small waves like sound waves and propagate in all media, but S waves are caused by transverse motion horizontal to the direction of travel, so the inside of the liquid (the outer or inner core of the Earth) can pass through. The'P' and'S' of the P and S waves correspond to the initials of "Primary or Push" and "Secondary or Shake", which mean the order and characteristics of the seismic waves arrive. wave), S wave (transverse wave).

Superface wave is mainly generated when a shallow earthquake occurs and propagates along the surface of the earth, Rayleigh wave has the property of a combination of P wave and S-wave vertical motion component SV wave, and love wave is As SH wave, which is the horizontal motion component of S wave, it propagates faster than Rayleigh wave and has only the motion horizontal component of the medium, so it is hardly recorded in the vertical component seismograph. The surface wave is the same as the wave propagating on the water surface, and the LR wave (Rayleigh wave) , LQ wave (Love wave).

When an earthquake occurs at the epicenter, the P wave and the S wave start at the same time, but due to the difference in the propagation speed, the P wave arrives and then the S wave arrives. The minute vibration of the horizontal component until the S wave arrives is initially initiated. It is called the fine motion time (PS time), and when an earthquake occurs at the origin, the P wave and the S wave start at the same time, but due to the difference in the propagation speed, the S wave arrives after the P wave arrives. The horizontal component until the S wave arrives The minute vibration of is called the initial fine movement time (PS), and the time that the initial fine movement continues becomes longer as the distance from the epicenter increases, so the true far distance can be calculated using this, and the first P wave is relatively large and The beginning is unclear, so there is usually no initial fine motion, because the seismic wave comes from almost vertically below.

In order to issue an early warning of earthquake occurrence, the above-described P wave and S wave must be detected and the scale must be analyzed. In addition, the PS time (the section where the minute vibration occurs immediately before the S wave after P wave is detected) must be detected. It plays a role as the main reference value (data) that can discriminate between artificial and natural earthquakes.

The standard-scale acceleration of the micro-vibration is about 0.8 to 25 [gal], and the maximum acceleration is about 0.1 to 6.7 [%g] (based on'Scale' of the Japan Meteorological Agency), and the intensity of'JMA' It refers to the Yakjin (弱震) corresponding to grades I to III (2.5 to 4.9 in Richter scale).

The above explanation is as the image below.

There are thousands of earthquakes occurring on Earth every day around the world, and most earthquakes are caused by large internal forces acting on continental movement, seafloor expansion, and mountain range formation over a long period of time.

Over the last 50 years, there have been about 500 thousand earthquakes with a magnitude of 7 or more occurring in various parts of the world, and the damage from earthquakes is gradually increasing.

An example of earthquake damage occurred on March 11, 2011 in Fukushima, Japan, with a magnitude of 9.0, causing a lot of damage to property and life due to the tsunami.

Even in Korea, which is said to be safe from earthquakes, large-scale earthquakes have not occurred, but an earthquake of magnitude 3.0 occurs twice a year, and the main earthquake of magnitude 5.4 that occurred in Pohang recently (November 15, 2017) and 4.0 that occurred continuously thereafter. The above dozens of aftershocks resulted in enormous property damage as well as many victims.

However, in the current earthquake monitoring system, the sensed sensor value is stored in the memory included in the earthquake monitoring system, and the administrator periodically downloads the saved sensor value using a portable memory (USB). Then, there is an urgent need for a method of monitoring whether an earthquake occurs through a sensor value that senses the vibration that occurs in real time.

In the Earthquake Monitoring System for earthquake damage prevention, rapid and accurate seismic wave detection is essential to determine the epicenter, origin time, magnitude, etc. when an earthquake occurs. The early warning system is based on two principles: the speed of light, the electromagnetic wave is faster than the seismic wave, and the speed is different according to the wave shape.

Earthquakes that occur when the fault breaks produce two waveforms with different speeds, P wave is 6-7 km per second, S wave is 3-4 km per second, and the average speed of P wave of the upper crust of the Korean Peninsula analyzed by the Korea Institute of Geoscience and Mineral Resources Is about 5.98 km/s and S wave is about 3.42 km/s.

A senior researcher at the Korea Institute of Geoscience and Mineral Resources said that the S-wave, which is a transverse wave, causes relatively great damage compared to the P-wave, which is a longitudinal wave, so the purpose of the earthquake early warning system is "The time of arrival before the S-wave arrives after observing the P wave first. "We are trying to reduce the damage by predicting the magnitude of the earthquake and by issuing a warning in advance."

The mass media, intellectuals, and government agencies report that "100% of students can evacuate under their desks if they know about an earthquake in '5 seconds' in advance."

The head of the International Urban Safety Engineering Center at the University of Tokyo, Japan, announced the relationship between the time of issuing the warning before the earthquake and the time of human injury. In 2 to 20 seconds, the probability of death, serious injuries, minor injuries, and free injuries was calculated.If the'indulgence time' is 2 seconds based on 100% damage when there is no warning, the death rate decreases by 25% to 75%. It is said that if the'free time' is 10 seconds, the death rate will be 10%, and if it is 20 seconds, it will decrease to about 5%.For example, when an earthquake occurs at a distance of 100 km from a city, 100 deaths will occur due to not receiving early warning. In the case of a situation, if an early warning is issued and preparations can be made 10 seconds before the earthquake reaches the earthquake, the number of deaths can be as high as 10, and evacuation actions are not possible if there is a margin of 2 seconds, but a safety posture such as head protection can reduce injuries. In addition, gas and electricity can be automatically cut off through the Internet. If 5 seconds is given, students trained at school can 100% evacuate under their desks, and in 10 seconds they can evacuate from indoors to outdoors, and in 20 seconds, families There is even room to tell them to evacuate, indicating the importance of early warning.

As an earthquake monitoring system in response to such a demand, Korean Patent Publication No. 10-1128491 applies an earthquake sensor that is installed at a specific location on the ground or structure to sense a vibration signal generated during an earthquake.

With such a conventional seismic sensor technology, in Utility Model Publication No. 20-0388579, a vibrating weight equipped with a permanent magnet that is hooked upward inside a cylindrical case and a printed circuit board with a reed switch installed in the side length direction of the vibrating weight are constructed, When shaking due to an earthquake or the like, the magnetic force of the vibration weight is separated from the reed switch, and the reed switch is converted from an "ON" state to an "OFF" state, and the signal is sensed by a microcomputer to control the fuel supply.

In addition, the vibration sensor of Korean Patent Application Publication No. 1998-702746 strikes a piezoelectric element composed of both sides by shaking when an additional weight, which is movably suspended at a pointed end, occurs, and the piezoelectric element is mechanically pressured as a result of the earthquake. It is possible to see a configuration that allows mechanical control by converting the signal into an electrical signal and transmitting the signal, but these configurations have a magnetic weight suspended on a support body so as to flow, and the weight of the weight is It is to detect a vibration signal or a switch configured around it according to the flow.

However, such a configuration has a disadvantage in that the detection function is deteriorated and the accurate and stable detection function is limited to the degree of shaking caused by an earthquake when it is limited to shaking due to rust caused by moisture while maintaining the weight added to the outside for a long period of time. .

In addition, the prior art of Japan, which has the technology for many earthquake detection devices due to frequent earthquakes, usually detects shaking of the deep underground ground. The seismic sensor of Japanese Patent No. 2010-14525 is a vibration body equipped with magnetic force. It is a technology equipped with a calculation means for calculating the detection signal by detecting the distance when the weight of the body is suspended by a spring and the additional oscillation occurs due to an earthquake.

In addition, the detector of Japanese Unexamined Patent Application Publication No. 2008-145115 has a metal ball placed on the vertical top, and the ball falls and lowers the switch unit configured in the lower part, so that the other side moves up and down while the switch unit is hinged. It is a configuration technology that detects whether there is an earthquake by operating a switch or the like.

In addition, the electromagnetic vibrator of Japanese Patent Publication No. 2008-39749 is installed with a magnet at the end of a weight hanging on a long string, and is installed as a sensing unit that detects magnetic force in proximity to the magnet. It is a technique of constructing to detect.

In addition, the seismic sensor of Japanese Unexamined Patent Application Publication No. 2006-226844 is configured to detect the distance of the weight to the upper portion of the weight, and the weight added to the spring due to an earthquake. Like the construction technology that detects the increase or decrease of the distance between the sensing unit and the sensing unit as it rises and falls due to the vibration caused by the ground, it is possible to detect earthquakes with the soft animal body linked by the ground shaking and the detection sensor configured around it, but to achieve the effect. It is composed of a swinging weight, a string to suspend the weight, or a spring having elasticity, and a sensor that detects the distance to detect the swinging weight or the magnetic force of the weight, so these configurations are easily used in a humid place for a long period of time. It has a problem that does not exert its effect when it is urgently due to a breakdown due to rust and a change in elasticity of the spring, and the composition is complicated and there are many disadvantages.

In addition, unlike the above, in the earthquake detection device of Japanese Unexamined Patent Publication No. 2009-156812, a plurality of groups of electric electrode units consisting of a pair of adjacent deep plates are formed, and a plurality of metal balls are provided in the center to prevent earthquakes. A pair of electric electrode units short-circuit the electrodes by hitting the electric electrode units configured around the metal ball while the dish is swinging, so that a change in resistance value according to the magnitude of the earthquake can be obtained.

This configuration is large due to the use of a wide plate-shaped plate, and the disadvantage of having to have a plurality of electric electrode parts due to the large number of metal balls swinging in all directions. In addition to the disadvantages of being unable to accurately detect due to limited friction, the above-described configurations have disadvantages that cannot be installed on home appliances, that is, small boilers, gas ranges, houses, and electric and electronic devices in companies.

As described above, the sensing device [感知裝置, sensor] is classified into tilt, gyro, position, and vibration sensor by magnetic sensor. The operating principle is the use of dictation and contact, Magnet vibration and coil induced voltage, leaf spring vibration and coil induced voltage, leaf spring. sinker. It is represented by the use of the contact relationship and the centrifugal force of the leaf ring, and at this time, a circuit that matches the condition with the used sensor (element) is attached according to the purpose.

In addition, the earthquake intensity of magnitude 5 means that you cannot walk unless you hold an object, and cupboards, tableware, and books in the bookshelf fall a lot, and unfixed furniture may collapse. At magnitude 6 or higher, it is difficult to stand and fix it. This is the case when most of the unused furniture moves and falls.

Sensors using magnetic materials described above include motor control, position detection, magnetic recording heads, etc. using Hall effect and magneto-resistance effect, and temperature sensing sensors and tilt function sensors by a combination of a reed switch and a magnetic material. .

In addition, there are cases in which the magnetization of a magnetic body or the structure of a magnetic domain is measured using the Kerr effect and the Faraday effect.

However, earthquakes are categorized into pre-jin, main- and aftershock, and it is technically very difficult to penetrate tens or hundreds of kilometers into the ground to know this pre-shock. In order to quickly determine the installation location and installation method of a sensor that can measure motion more precisely and whether gas is blocked in the event of an earthquake, Sl (Spectrum Intensity), which is closely related to the energy of the seismic wave and PGA (Peak Ground Acceleration), is measured in real time. We have developed an algorithm that calculates by and implement it in an earthquake detection system.

As described above, it is most important to predict earthquakes in advance, evacuate in advance, and block dangerous devices, but the current technology is not accurate and the effect is not significant, so an earthquake occurs as in the preceding technologies. After that, it is becoming more common to control dangerous devices by detecting vibrations caused by the earthquake.

Accordingly, in Japan, a country with a large number of earthquakes, the inclination of an object that vibrates by an earthquake is approximately 15 in order to safely keep devices that use oil, gas, precision electronics, and electrical machinery, as well as devices that use oil and gas, and prevent explosions or fires. The province detects this and regulates to cut off dangerous factors, such as oil, gas, and high-pressure electricity.

Korean Patent Publication No. 10-2014-0030915 has been proposed as an earthquake detection device to satisfy these regulations, which is equipped with a stopper for fastening to a vertical or horizontal plate member or a PCB plate composed of a mechanical device with risk factors. A body part comprising a fastening rod and a lid part fastened to the body part, wherein the body part is opened and closed by a lid part and formed into a groove of a certain depth, a sensing ball moving path, a sensing ball movable in the sensing ball moving path, It has a form composed of a detection sensor for detecting a detection ball provided in the detection ball movement path.

Such an earthquake detection device provides a magnetic flow path instead of a magnetic weight in the conventional reed switch and magnetic weight method, so that it is relatively inexpensive and accuracy can be improved compared to the prior art.

However, most conventional vibration detection-related sensors, including the above-described earthquake detection device and gyro sensor for detecting tilt or acceleration, are configured to detect only one direction or 2D (short axis direction), so when installing the detection device, the direction and angle are accurately adjusted. In addition, it is not possible to accurately distinguish between natural earthquakes with vibration energy of P-wave and S-wave and explosions with only vibrational energy of P-wave, or shock or simple vibration. There is a problem in that it is not possible to accurately exert an alarm signal to be used in a short time, and thus, it is not possible to minimize an earthquake disaster.

In other words, in the conventional detection of earthquakes, it is a general matter to use the law of inertia for the detection of earthquakes (vibrations), and general earthquake detectors mainly detect amplitude and output through electrical circuit contacts, but to know the impact strength of a realistic earthquake. There was also a problem that could not be.

In addition, in seismic detection, it is common to operate only with P waves that vibrate in the left and right, back and forth, or without distinction between P and S waves, and 3D sensors using permanent magnets and coils also have three permanent types. As a structure in which only the direction of vibration is changed in a set of a magnet and three coils each, there is a problem in that there is a limitation in analyzing the type of seismic wave or impact strength.

In the content of a paper in Korea, one of the most important analysis processes in an earthquake monitoring system is to detect the initial P wave caused by an earthquake.

Although various and sophisticated algorithms have been developed and used to more accurately detect the initial P wave, most of the methods are not practical for real-time seismic wave analysis, and compared to them, STA/LTA (Short Term Average/Long Term Average). The method has the advantage of being able to calculate simply by assuming that the initial motion of the P wave is detected when the ratio of the sum of the squares of the earthquake waveform amplitude in the short time interval and the sum of squares in the long time interval exceeds the limit point.

Therefore, it has been argued that most earthquake early warning systems detect the first wave P wave using the STA/LTA method, which can be calculated simply, and most of them operate the'early earthquake warning system' adopting this method.

However, while pointing out that the STA/LTA-type technology has a disadvantage that requires a large amount of data storage space and pre-processing such as Hilbert transform, which requires a large amount of computation to obtain the signal change rate, the amount of change in the time-frequency domain and An earthquake detection apparatus and method based on time-frequency variation for detecting P waves based on variable threshold values are described in the paper, but this also has a problem in commercializing low-cost, low-cost or portable products.

Another paper in Korea has proposed a method for removing various noise signals added when collecting earthquake data in a low-end local Earthquake Disaster Preventing System (LEDPS) using multiple MEMS sensors, but this requires precise data. There is a problem in commercializing it as a low-cost entry-level or portable device that can be easily purchased and used because it is expensive enough to be used by the meteorological agency or large research institute.

The following is a summary of the content presented in it by citing another paper in Korea (Noise Reduction of Seismic Waves Using Micro-Position Array Polymerization).

Currently, in Korea, it is the initial stage of the development of an earthquake early warning system, and a design and implementation method of a seismic data acquisition system using a low-cost, low-cost MEMS acceleration sensor has been announced to alleviate earthquake disasters in living areas.

However, MEMS acceleration sensors are suitable for measuring seismic waves over medium-sized (Richter scale 4.0) or larger where damage is expected, and the system cost can be reduced, but due to the unique characteristics of the sensor compared to expensive seismic observation sensors. There is a disadvantage in that the level of additive noise is high.

Noise added during seismic data collection (detection) is mainly generated by the sensor itself or added during measurement, such as offset noise and thermal noise caused by misalignment of the bearing and the ground when the sensor is installed. The measurement noise of random characteristics, and the environment of the installation site (i.e., low-frequency noise due to wind, waves, air pressure, etc. in the case of an earthquake observing station where people are rare, and blasting of people, vehicles, construction sites, etc. in the case of living areas, etc. It appears in the form of background noise having a coherent characteristic due to noise).

The decrease in the signal to noise ratio (SNR) due to the additional noise makes it more difficult to detect P-waves having a relatively small amplitude compared to S-waves in a single observation system.

Therefore, in order to process various data for accurate seismic element analysis (post-processing), it is presumed that efforts to remove various additional noises must be preceded in the initial stage of sensing seismic data. Although the Local Earthquake Disaster Preventing System (LEDPS) proposes a method for removing various noise signals added when collecting earthquake data, this also has a problem to commercialize it as a low-cost entry-level or portable.

The above papers and journals have disadvantages in that it is impossible to accurately determine seismic factors because the seismic wave detection performance is significantly degraded because the amplitude of seismic waves and background noise are not accurately distinguished when a small earthquake occurs. Since it has been developed for the above measurement, it appears that it does not detect minute vibrations in the PS area, which is important for determining natural and artificial earthquakes, which is insufficient to apply to accurate earthquake warnings.

In addition, the thesis or journal does not mention the exact structure or composition of the sensor, but most of them are only described as acceleration sensors, and since the point of view is only on the magnitude of the earthquake that causes damage, a leap of 25 gal or less (fine vibration) Is ignored, and most of them are described only for detection of 25 gal or more, which is medium or higher, so it can be said that the distance is far from the popular type or the precise detection type.

Most of the above-described detection sensors have direction constraints during installation and detection, and in order to solve this disadvantage, a product price increases because several sensors are used in combination for each direction.

On the other hand, earthquake early warning systems, which are usually installed at the national or government level, have sensors that frequently generate ambient noise, such as'passing railroads such as vehicles or trains, around stations, around construction sites, near airports or ports or near terminals, subway stations, or They are rarely installed in places such as subway tracks, bridges or bridges, and are mostly buried underground in seismic observatories with rare access and protected access, so artificial earthquakes can detect nuclear tests or large explosions. Although there are often cases, there may be little room for malfunction due to'sensor's own noise, circuit noise, and errors in computational processing' because miscellaneous vibrations, which are general living noise vibrations, are not detected. As it is being applied, it is a reality that the problem does not arise, and the possibility of malfunction of vibration detection is low, but it is not a product of popular or generalized technology, and the overall facility price is very high.

However, the so-called'vibration detection, detection and analysis and alarm function device' should not be a product used in a limited place in terms of national management, and its core purpose is to use it for earthquake occurrence detection, but Various discrimination processes and algorithms of software computational processing in the process of calculating, comparing and determining the set data (value) of the judgment criteria and the detected data are modified through a predetermined change process, that is, can be used for other purposes. It should be a product that must be satisfied as a vibration detection device (refer to Table 1 of characteristics of vibration in general life below).

In order to achieve the above objectives, vibration characteristic analysis should be possible, errors in discrimination between artificial and natural earthquakes should be minimized, and above all, it should be inexpensive, popular and universal, and suitable for various vibration detection fields. It is required that the application or convergence application should be easy, there should be no scarcity of constituent materials or parts, and should be able to minimize pollution damage to the environment.

On the other hand, none of the conventional handrails have been presented with an alarm device having a vibration detection function and a vibration analysis function.

Korean Patent Publication No. 10-2014-0030915 (March 12, 2014) Korean Patent Publication No. 1998-702746 (August 5, 1998) Korean Patent Publication No. 10-1674012 (November 02, 2016) Korean Patent Publication No. 10-2013-0128288 (November 26, 2013)

The present invention is conceived to solve such conventional problems, and relates to a disaster and disaster warning device using a complex detection sensor, and in more detail, "X, Y, Z 3-axis" or "360° omnidirectional In a directional premise called "or "3D", a high-sensitivity vibration detection sensor that detects minute changes in physical kinetic energy (vibration/shake, acceleration, fall/rise, rotation, movement, stop, etc.) reflecting the acceleration of gravity in that direction It receives as a digital signal through a vibration transmission medium and an analog signal through a piezoceramic piezoelectric sensor composed of a piezoelectric element, and the presence or absence of a vibration detection signal due to shock or earthquake, and the period, continuity, and occurrence time of the vibration detection signal and Detection of time, frequency of vibration detection signal and presence or absence of fine vibration, change amount (value, data) and set threshold of vibration detection signal, comparison reference value, calculation of limit values, comparison, temporary storage of information, temporary Based on the result of computational processing such as erasing memory information, the intensity of vibration and the type of vibration are automatically detected to accurately identify natural and artificial earthquakes, and according to the amount of change and detection value of the intensity, duration and frequency of the vibration. It judges the'earthquake interest stage','attention warning (evacuation preparation) stage', and'evacuation warning stage', and depending on the result, an alarm or an evacuation signal is audible or visually recognized by an unspecified person. Its purpose is to provide an alarm device with non-directional vibration detection function and vibration analysis function that can minimize various disasters that may occur due to earthquake by providing alarm sound or legal standard signal.

Another object of the present invention is that it can perform its role even when it is installed in a non-limiting direction and angle regardless of an inclined installation angle or horizontally or vertically, and has a main purpose of detecting natural seismic vibration, in particular, It can be used by being mounted on the inside or outside of an LED lighting lamp, or because it has a function to detect the type of vibration and to detect the magnitude of the vibration, it can be modified for other purposes, and can be used as'theft intrusion detection security device','train Crossing automatic circuit breaker management','Nuclear test detector','The sound of footsteps (vibration) of harmful animals invading the farming area','Automatic power breaker of the switchboard in the event of an earthquake Unmanned anti-theft device for tangible property such as vehicles','landslide preliminary warning device','automobile tunnel entry detection device used for lighting dimming control','breakage or collapse of bridge', etc. It is to provide an alarm device having an omni-directional vibration detection function and a vibration analysis function that can perform various modifications (use or integrated application) such as the tower's strong wind damage prevention management detection.

Here, to describe the detailed information related to the natural earthquake, the interest in earthquakes has increased at home and abroad as a large-scale earthquake in Korea and Gyeongju, Pohang, Haiti, and Northeastern Japan caused a lot of human and economic damage. Although earthquakes in themselves cause great damage, they cause additional secondary disasters such as fire, explosion, leakage, electric leakage, and nuclear accident.

However, since earthquakes cannot be predicted with science and technology at present, it is necessary to reduce the damage caused by earthquakes through prompt notification and response in case of earthquakes rather than predicting. Therefore, advanced countries including the United States, Japan, and Taiwan developed earthquake early warning systems. Efforts are being made to reduce the damage, and in general, when an earthquake occurs, the longitudinal P wave (speed: 7-8 Km/s) propagates the fastest, followed by the S-wave (speed: 3-4 Km/s), which is the most damaging transverse wave. Is propagated.

The earthquake early warning system detects the P wave with the fastest propagation speed, promptly notifies whether an earthquake occurs before the S wave reaches, and controls major facilities to reduce damage caused by earthquakes. In Korea, it is very important to detect the occurrence of an earthquake quickly and accurately. In Korea, when an earthquake is detected, the Meteorological Agency quickly determines whether or not the'earthquake breaking news' is to be sent out, and the earthquake breaking news is issued based on the'modified Merkaly magnitude'. The standard is 3.5 or higher for inland areas and 4.0 or higher for coastal and sea areas, and " The Modified Mercalli Intensity Scale" is used in Korea.

On the other hand, another object of the present invention is to install the device of the present invention on the upper surface of the railing support, so that unspecified persons accurately recognize the state of vibration and earthquake occurrence at any place where the railing is installed (ie, regardless of the location). It is to provide a railing including an alarm device having an omni-directional vibration detection function and a vibration analysis function that can minimize various disasters that may occur due to an earthquake by taking actions accordingly.

In addition, detailed objects of the present invention will be clearly understood and understood by experts or researchers in this technical field through specific contents described below.

The device of the present invention for achieving the above object is installed in an unspecified place, including various electric/electronic devices or devices, and is used in various equipment that needs to immediately notify or alert an unspecified person when an artificial or natural earthquake occurs. In constructing an alarm device having an omni-directional vibration detection function and vibration analysis function that can be installed and used without being largely restricted, it is connected to the internal printed circuit board through a power supply terminal from the outside of the main body, A DC power supply unit for constantly supplying a DC voltage required for driving an electronic component; In the state of being mounted on the printed circuit board in the main body, in an omni-directional premise called "up/down, left/right, front/rear, X, Y, Z 3 axes" or "all directions 360° forward orientation", the acceleration of gravity is reflected All-round high sensitivity that enables the CPU to take data such as vibration status and duration by detecting changes in mechanical (or physical) kinetic energy (vibration, shake, fall, rise, fall, rotation, stop, etc.) in real time with a digital switching signal A vibration detection sensor; In addition to causing physical vibration stimulation (physical stimulation such as distortion, compression or tension) that is directly transmitted through a vibration transmission medium that acts as a mechanism for movement of the center of gravity in an undirected direction in which vibration transmission is not specified, It has a configuration that is transmitted indirectly through the lower case, and the amount of change corresponding to the intensity of vibration applied from the outside is analogue when installed horizontally or vertically from one side of the body or horizontally on the top or bottom of the body. By detecting the signal in real time, the CPU can detect the magnitude (intensity and amplitude) of the vibration, the frequency of the vibration, the duration of the vibration signal, etc., and at the same time, it can detect fine vibrations and higher vibrations of medium and strong vibrations.

In the above, the various equipments that can be used by selectively installing the device of the present invention are'LED lighting control device','theft and intrusion detection security device','train crossing automatic breaker control device','nuclear test and bomb test.

Meanwhile, the DC power supply unit 10 among the components of the apparatus of the present invention is connected to the internal printed circuit board 200 through the power supply terminal 21 while being installed outside the main body 20 It has a function of always supplying DC voltage required for driving electric and electronic parts.

In addition, the omnidirectional high-sensitivity vibration detection sensor (S1) has various types of configurations as described later, and in a state mounted on the printed circuit board 200 in the main body 20, "up and down, left and right, front and rear, X, Y , Z 3 axis" or "360° omnidirectional premise", mechanical (or physical) kinetic energy (vibration, sway, fall, rise, fall, rotation, stop, etc.) that reflects the gravitational acceleration corresponding to that direction. ) The change amount is detected in real time as a digital switching signal, and then transmitted to the CPU 40, so that the CPU 40 can take data such as vibration status and duration.

In addition, the piezoceramic piezoelectric sensor S2 also has the same configuration as in the embodiments to be described later, and is installed horizontally or vertically from one side of the main body 20 as shown in (a) (b) of FIG. 2A. As shown in (a) (b) of 2b, when installed in a horizontal direction on the top or bottom of the main body 20, vibration transmission that acts as a mechanism of movement of the center of gravity in an undirected direction in which vibration transmission is not specified It generates a physical vibration stimulus (physical stimulus such as distortion, compression, or tension) that is directly transmitted through the medium 350 and performs a function of indirectly transmitting it through the upper and lower cases 330 and 310.

In other words, the piezoceramic piezoelectric sensor (S2) is installed in a horizontal direction or vertical direction on one side of the main body 20, or horizontally on the upper or lower surface of the main body 20, and is applied to the intensity of vibration applied from the outside. The corresponding amount of change is detected in real time as an analog signal and then transmitted to the CPU 40 so that the CPU 40 can detect the magnitude (intensity and amplitude) of the vibration, the vibration frequency, the duration of the vibration signal, etc. At the same time, it performs a function to detect microscopic vibrations and vibrations of the medium and strong vibrations that are more than that.

In addition, the key input unit 30 is installed in a form connected to the input terminal of the CPU 40 so that the user can input various setting data into the CPU 40, start control, and perform a manual reset. Perform.

In addition, the CPU 40 is basically the vibration of digital switching signals and analog signals input in real time from the omnidirectional high-sensitivity vibration detection sensor (S1) and piezoceramic piezoelectric sensor (S2), respectively, as shown in the flowchart shown in FIG. After receiving the detection signal, analyze and calculate the'amplitude, frequency, and duration' of the analog vibration detection signal value, analyze the'signal occurrence and duration' of the digital switching signal, and then process the final computation. It performs a function of comparing the value with the “low level value, the middle level value, and the upper limit level value of the three-step reference determination value” set in advance according to the vibration scale (earthquake intensity).

In addition, the CPU 40 determines whether two vibration detection signals detected in real time by the omnidirectional high-sensitivity vibration detection sensor S1 and the piezoceramic piezoelectric sensor S2 are detected in conjunction with each other, and the piezoceramic piezoelectric It analyzes whether the sensor's waveform characteristics were detected separately as'S wave' and'P wave', and controls the type of vibration to be able to distinguish as much as possible, while controlling the'predictive management scale' of earthquakes. It can be set in advance, and it compares with a preset'preliminary alarm management scale (vibration level)' and performs a function of visually and aurally recognizing a plurality of staged alarms to unspecified people according to the determination result.

In addition, the comprehensive alarm condition output unit 50 has a function of generating a light or an alarm sound of a predetermined color so that unspecified persons can recognize the degree of disaster occurrence through visual and audible in response to the control signal output from the CPU. Perform.

At this time, the general alarm condition output unit 50 is a green light-emitting diode so that a general display or alarm can be performed by dividing an interest alarm step, a temporary evacuation alarm step, and an outdoor evacuation alarm step in response to the output signal of the CPU 40. And a red light-emitting diode, a buzzer (siren), or a speaker.

On the other hand, in the present invention, by further installing a charge/discharge control circuit unit 60 between the DC power supply unit 10 and the CPU 40, the storage batteries 70 are supplied using the output voltage of the DC power supply unit 10. After charging, the voltage charged in the storage battery can be supplied to each electronic device when the power supply is cut off or a power failure occurs.

In this case, the DC power supply unit 10 is not limited to a rectifier circuit that rectifies the AC voltage to a DC voltage as shown in FIG. 1, but instead of the DC power supply unit 10 as shown in FIG. ) And the above-described charging and discharging control circuit unit 60 and storage battery 7 are further installed, and various electric and electronic devices through the charging/discharging control circuit unit 60 using the voltage generated through the solar cell 11 DC voltage required for driving each electric device by using the voltage charged in the storage battery 70 when power supply is cut off or power failure occurs after charging some voltage to the storage battery 70 while always supplying the DC voltage required for driving the component. It can also be supplied by.

In addition, in the present invention, a diode (D) for blocking supply of continuous voltage and a capacitor (Cx) for removing noise are further installed in parallel between both terminals of the piezoceramic piezoelectric sensor (S2) to include damage to parts due to reverse voltage. Therefore, it is possible to prevent errors in the vibration detection signal due to noise.

In addition, an amplifier 80 having a variable resistance VR for adjusting the amplification degree is further installed between the output terminal of the piezoceramic piezoelectric sensor S2 and the input terminal of the CPU 40, and the piezoceramic piezoelectric sensor S2 ) So that the vibration detection signal detected by the amplification degree can be amplified by the amplification degree determined by the variable resistor (VR) for adjusting the amplification degree and transmitted to the CPU 40, that is, the CPU 40 grasps the correct vibration and earthquake and is required. It was made to generate an output signal.

On the other hand, in the CPU 40, as shown in FIG. 4, a "digital switching signal" input from an omnidirectional high-sensitivity vibration detection sensor S1 capable of detecting an earthquake vibration having a low scale within a range of about 0.5 to 25 [gal] Piezoceramic piezoelectric sensor (S2) capable of analyzing the characteristics and variation of the'switching duration and whether the switching signal is generated' and detecting earthquake vibrations of about 20 to 25 [gal] or more corresponding to the earthquake scale A control program is provided to analyze the amplitude of the'analog detection signal (piezoelectric electromotive force signal)' input from the signal and the characteristics and variation of the time and frequency of the continuous generation of the detection signal, and distinguish between natural and artificial earthquakes. And, by analyzing the detection value of the earthquake vibration scale determined as a natural earthquake, the preset'alarm management earthquake vibration scale value' and the data of the detected scale are compared and determined, and then the output signal of the alarm stage corresponding to the detected value It also performs a function of visually or aurally recognizing a large number of unspecified persons by outputting it to the comprehensive alarm condition output unit 50.

In addition, as a result of real-time analysis of the vibration detection signals input from the all-round high-sensitivity vibration detection sensor S1 and piezoceramic piezoelectric sensor S2 from the CPU 40, earthquakes belonging to weak earthquakes Ⅰ to Ⅲ As a class (ie, earthquake Ⅳ grade (JMA, Japan Meteorological Agency regulations) or lower), the acceleration is about 0.5 to 25 [gal], which is a weak vibration (preliminary tremors/initial micro motion). The'digital switching signal' is continuously detected through the all-round high-sensitivity vibration detection sensor (S1) for 0.1 to tens [seconds] or more, and the'analog detection signal (piezoelectric electromotive force signal)' detected from the piezoceramic piezoelectric sensor (S2) The detection waveform characteristic is divided into two stages,'S-wave' and'P-wave', and is detected, and the analog detection signal and digital switching signal of more than a preset amplitude are detected, as well as the'fine vibration duration'. If it is detected for several to tens of seconds, it is determined as a natural earthquake, and a control signal suitable for the magnitude of vibration (amplitude level), which is the level of the'analog detection signal', is output to the general alarm condition output unit 50 to produce a number of unspecified numbers. It performs a control function that makes people perceive visually or auditoryly.

In addition, the CPU 40 first, when receiving a digital switching signal from the omnidirectional high-sensitivity vibration detection sensor (S1), determines whether it is a natural or artificial earthquake'fine movement before the initial P wave entry and after the P wave entry and S wave It analyzes the'holding time of micro-vibration before entry' to determine whether it is a natural or artificial earthquake, and uses the detection time as one of the variables for determining the type of vibration.

Subsequently, the number of detections of the potential (voltage) of the amount of electricity generated through the piezoceramic piezoelectric sensor S2 according to the vibration per unit time is sampled from several to several hundred times per second, stored as data in a temporary storage location, and automatically Carry out the steps to carry out the cyclic flow erasing.

Thereafter, the CPU 40 samples the detection of the potential of the piezoceramic piezoelectric sensor S2 for tens to thousands [msec] and detects the number of minimum and maximum values among the data recorded in the temporary storage error and noise. Determining and excluding, summing the remaining data, dividing by the number of the data and calculating an average value to derive the average data value of the vibration scale is performed.

Next, the P-wave and S-wave are compared with the three-step reference value ('vibration scale comparison' reference data/Standard Reference Data) of seismic vibration determination set in advance and the data values taken as average Perform the step of comparing and judging whether the vibration has occurred and to what extent (scale).

Thereafter, the CPU 40 calculates the maintenance time of fine vibration generation after P wave detection, the time interval of P wave and S wave, P wave generation maintenance time, and S wave generation maintenance time, and then comprehensively artificial earthquake. And processing as one of variables for determining vibration and natural earthquakes, and performing a period/time computational process in which an average value is calculated and compared with a reference data value.

Next, in order to obtain high quality and clear vibration data, only the data value within the predetermined frequency band is taken, and the data value of the analog detection signal of about 2.4 [gal] or less detected from the piezoceramic piezoelectric sensor (S2) is discarded, and the analog detection signal and digital The step of taking only the detection signal value of the vibration in which the two detection data of the red switching signal coexist is performed.

On the other hand, the comparison reference setting value and setting (management) regulations and judgment criteria for the duration (maintenance) time for each item, input through the key input unit 30 in the CPU 40 to determine natural and artificial earthquakes It is as shown in "Table" below.

That is, in the CPU 40, when the detection duration of fine vibration before P-wave detection is 500 [msec] or more, it is determined as a natural earthquake vibration, and counting the detection duration of fine vibration after entering the S-wave is unnecessary. It is judged as a natural earthquake when the duration of the micro-vibration between the P wave and the S wave is 2 to 20 [seconds] or more, and if the duration of the P wave is more than 2 seconds, it is judged as a natural or artificial earthquake. , If the duration of the S-wave is more than 2 [seconds] after the P-wave is detected, it is judged as a natural earthquake, and if the repetition interval of one cycle of the P-wave and S-wave is at least 5 seconds, it is judged as a natural earthquake.

In addition, the analysis and comparison criterion setting value and setting (management) regulation and judgment criterion for the vibration frequency for each item, input through the key input unit 30 in the CPU 40 to determine natural and artificial earthquakes, are as follows: Same as "table".

That is, in the CPU 40, when the frequency of the switching signal detected by the omnidirectional high-sensitivity vibration detection sensor S1 is about 2 to 200 [Hz], it is determined as a natural earthquake, and the vibration generated by the piezoceramic piezoelectric sensor S2 is detected. When the frequency is about 1 to 500 [Hz], it is judged as a natural earthquake.

Here, an example of the waveform of the natural earthquake waveform and the artificial earthquake or noise vibration is as follows.

On the other hand, the CPU 40 determines to what extent the magnitude (intensity) value of the detected natural earthquake, input through the key input unit 30 in order to determine the natural and artificial earthquakes, and what alarm should be given. The seismic level management standard category items and the limit (threshold) range data (value) of the acceleration of the alarm stage of the earthquake scale are shown in the "Table" below.

That is, when the apparatus of the present invention is in a state where earthquakes occur frequently and is installed in a place or area where vibration suppression measures are well taken, the vibration acceleration in the CPU 40 is about 29 gal. ] When it is detected below, it is judged as a warning level of interest, when it is detected as 30 to 100 [gal], it is judged as an evacuation preparation warning and a temporary evacuation stage, and when it is detected above about 101 [gal], it is judged as an evacuation (evacuation) warning stage. To be able to judge.

In addition, when the device of the present invention is in a state where earthquakes do not occur frequently and is installed in a place or area where vibration suppression measures are insufficient, the vibration acceleration in the CPU 40 is approximately 25 [gal]. When it is detected below, it is judged as a warning of interest, and when it is detected as 26 to 80 [gal], it is judged as an evacuation preparation warning and a temporary evacuation stage, and when it is detected above about 81 [gal], it is judged as an evacuation (evacuation) warning stage. Be able to judge.

In addition, when the apparatus of the present invention is installed in a place or area where earthquakes occur frequently and there is no anti-vibration countermeasure, the vibration acceleration in the CPU 40 is about 20 gal. ] When it is detected below, it is judged as a warning level of interest, when it is detected as 21 to 60 [gal], it is judged as an evacuation preparation warning and a temporary evacuation stage, and when it is detected above about 61 [gal], it is judged as an evacuation (evacuation) warning stage. To be able to judge.

In addition, the CPU 40 determines the degree of vibration and properly operates the general alarm condition output unit 50 so that the relevant condition, alarm stage, and notification contents are shown in the "Table" below.

That is, as a result of determining the degree of vibration by the CPU 40, when it is determined as a temporary evacuation (preparation for outdoor evacuation) alarm stage, a green light emitting diode, a red light emitting diode, and a buzzer ( Siren) or only the red LED of the speaker blinks at 0.5 Hz and then turns off after a delay of 3 seconds.If it is judged as an outdoor evacuation warning stage, the green LED and the red LED are set at 2 Hz 1 cycle. It operates to make the intersection flicker, but after that, even after the maximum value of S wave disappears, it maintains the above state for 3 to 5 minutes, as well as activates the buzzer (siren), and detects the lower limit of the P wave and piezoceramic piezoelectric sensor (S2). In the case of medium, only the red light-emitting diode maintains the "on" state, and if any one of the P-wave or S-wave piezoceramic piezoelectric sensors (S2) is being detected, the green light-emitting diode maintains the "on" state and red The light-emitting diode blinks once every 0.5 seconds, but the buzzer (siren) turns "off", and in the case of detecting the upper limit of the piezoceramic piezoelectric sensor (S2) of the S wave, the green light-emitting diode and the red light-emitting diode are intersected every 0.5 seconds. It blinks, but the buzzer (siren) turns it off.

It functions as both fixed terminals of the switch that transmits the switching signal to the CPU 40 side of the printed circuit board 200 and serves as a terminal for fixing to the printed circuit board 200 through soldering.

In addition, since the first and second weight balls 120 and 130 function as a movable terminal of a switch between the pair of electrodes 110, the whole is formed of a conductive material or only the surface is deposited. It is molded to have a shape in which a conductive layer is formed through the like, but has a shape molded to have a predetermined diameter and mass as described later.

The first and second weight balls 120 and 130 are formed in the cylindrical space 101 of the tubular body 100 and the pair of electrodes 110, respectively, as shown in FIG. In the state of being installed in the seating groove 112 so as to be able to flow and roll in all directions, when vibrations due to external shocks occur, up, down, left, and right in response to the direction and degree of inclination. It flows and rolls in a 360° forward direction, before and after, and functions as a movable terminal of a switch to generate an electrical on/off switching signal between the pair of electrodes 110.

At this time, the ball flow formed in the pair of electrodes 110 in the cylindrical space 101 of the tubular body 100 and the space between the seating groove 112 is installed to be able to flow in all directions. When the outer surfaces of the first and second weight balls 130 are in contact with each other as shown in Fig. 8A, a portion of the outer surface of each of the balls flow and seating groove 112 provided in the pair of electrodes 110 If it remains in contact with the inner surface, a switching "on" signal is generated.

However, the outer surfaces of the first and second weight balls 120 and 130 are in a non-contact state as shown in FIG. 8(b), or the first and second weight balls 120 and 130 Even if the outer surfaces are in contact with each other, a switching "off" signal is issued when any one of the weight balls does not contact the inner surfaces of the ball flow and seating groove 112 provided in the pair of electrodes 110, respectively. Is done.

On the other hand, the inner surface of the ball flow and seating groove 112 provided in the insertion portion 111 of the body of the electrodes 110, respectively, and the outer surfaces of the first and second weight balls 120, 130 are formed smoothly. In the case of moving, when the ball moves up, down, left, right, front and rear 360° in front, in response to an external shock or tilt of the omnidirectional high-sensitivity vibration detection sensor (S1), between the outer surfaces of the weight balls And there is a possibility that a desired switching signal cannot be obtained due to large mutual sliding between the outer surface of the weight balls and the inner surface of the ball flow and the seating groove 112.

Therefore, in the first embodiment of the present invention for the omnidirectional high-sensitivity vibration detection sensor (S1), as shown in FIG. 7, the ball flow and seating groove 112 provided in the insertion part 111 of the body of the electrodes 110, respectively. ), as shown in (a) (b) of FIG. 8 or on the outer surface of the first and second weight balls 120, 130, or both of the inner and outer surfaces of the friction force increasing means 150 were provided.
