Description

The combined configuration of free field and remote signal sources and its earthquake detection system

This work is about earthquake detection; specifically about earthquake detection methods and devices using multiple sensors, especially those used in areas with large-scale unnatural, non-seismic vibrations such as tracks.

Most natural disasters, such as typhoons and volcanic eruptions, can be predicted hours to days in advance. However, the occurrence of an "earthquake" is unpredictable, and there are even no signs before it occurs. Try to detect earthquakes early to reduce damage. Because the speed of seismic waves increases from fast to slow, they can be divided into "P waves" and "S waves". Among them, the S wave is more destructive but slower, and is the latest to reach the surface (Free Field); while the P wave, which has small amplitude and low destructive power, is faster and reaches the Free Field the fastest, so it is undergoing earthquakes. In early warning, earthquake detectors can be used to detect seismic waves to provide early warning, issue warnings and take measures before serious disasters occur. The specific prediction method is to use the characteristics of the P wave with the fastest wave speed and the earliest arrival to predict the early warning of the S wave that will arrive later. The current mainstream earthquake early warning or sensing systems are mainly divided into regional and local types. The general principle of regional earthquake is based on the basic method of locating and determining the scale of earthquakes. The technology of "regional earthquake early warning" can be shortened to about 20 seconds. As for the On-site Earthquake Early Warning System, it is an early warning method that uses a few seconds of information after the earthquake observation station deployed in a certain place is triggered to instantly judge the destructiveness of an earthquake and issue warning messages to the local area. This mode generally relies on individual station triggers, which can effectively reduce the cost of early warning deployment and narrow the scope of early warning blind spots.

However, earthquake detectors often misjudge earthquakes due to surface vibrations caused by human activities (such as people running, passing vehicles, construction sites, heavy industrial factories). Therefore, how to avoid unnatural factors from causing misjudgments by earthquake detectors is also one of the current research directions. Conventional technology such as the Republic of China Patent No. I541528 discloses the installation method of the sensor, but does not disclose the prerequisites for use and applicable fields. In addition, it does not disclose the use of remote signal sources as local (local) earthquakes. The detection system is the source of the auxiliary sensing signal, so its effectiveness in reducing misjudgments is limited. If other sensor failures occur or signals cannot be transmitted, the probability of misjudgments will increase. As for the Republic of China Patent No. I553327, although it is proposed that human activities will cause misjudgments of seismometers, its solution is to judge by a single threshold value. When there are several types of unnatural vibrations in the field, this one The method is prone to misjudgment.

Therefore, the main purpose of this creation is to provide an earthquake detection system with special planning for various places that need to be protected. To this end, the applicant has worked hard to propose the "free field and remote signal source" of this creation. "Combined configuration and its earthquake detection system" to avoid misjudgments caused by unnatural surface vibrations and improve the accuracy of earthquake judgments.

In order to avoid misjudgment of the occurrence of earthquakes due to unnatural factors and prevent vibrations caused by human activities from interfering with the detectors, this creation uses a plurality of sensors installed at different locations to achieve a verification effect. Only each sensor When both sensors confirm that there is an earthquake, an earthquake warning will be issued to the protected site. Sensors set up in two different environments are used to avoid the same interference that two sensors may receive in the same environment. The lack of misjudgment. The "combined configuration of free field and remote signal sources and its earthquake detection system" of this creation further refers to its application in rail transportation or similar environments where there is a lack of suitable installation of wired auxiliary sensing devices in the field. The characteristic of the environment is that vibrations occur frequently in the field. Compared with the vibrations caused in factories, the vibration patterns of the two are different. For example, the vibrations generated by rail vehicles can be transmitted up to one or two kilometers, so even if the free field sense The horizontal distance between the detector and the track has reached tens of meters, so it may still be interfered with and cause misjudgment. By setting up sensors in two different environments, the misjudgment of the same interference that may be received by two sensors in the same environment is avoided. Therefore, this creation is aimed at such an environment, optimizing the location of the sensor. In addition to setting up the sensor on the free field, it also performs sensing through the remote end, that is, through a network connection. Receive a sensing signal from the remote end. This sensing signal can come from a separate sensor, which has a communication interface to transmit the remote signal to the local host through the network, and comes from The remote signal of the remote sensor is a measurement value; or the sensing signal is a sensing signal generated by another earthquake detection system at the remote end, and this sensing The signal is a trigger signal. It can be seen that this invention, through remote sensing operations, can fully prevent the local free-field sensors from misjudgment due to non-seismic, unnatural, or artificial interference sources, thereby improving the accuracy of detection. and reduce the waste, such as time cost, caused by misjudgment of the track.

Therefore, in order to achieve the above purpose, this invention provides an earthquake detection system that is configured with a combination of free field and remote signal source, including: a host; a main sensor, which is set in a free field and connected to the host. line; an auxiliary earthquake detection system, wherein the auxiliary earthquake detection system is remotely located relative to the main sensor and is connected to the host through a network to transmit a remote signal to the main sensor. host.

In order to achieve the above purpose, this invention further provides an earthquake detection system that is configured with a combination of a free field and a remote signal source, including: a host; a main sensor, which is set in a free field and connected to the host. line; and a plurality of auxiliary sensors, all remotely located relative to the main sensor, wherein each auxiliary sensor is connected to the host through an Internet network and transmits a remote signal to the host. host.

This invention can be fully understood by the following examples, so that people skilled in the art can complete it. However, the implementation of this invention is not limited by the following examples.

In this disclosure, the on-site earthquake warning station may include sensors and computing modules.

Please refer to the first figure, which is a schematic diagram of one embodiment of the system 10 for judging earthquakes and estimating seismic wave intensity in a single operation (that is, it can actually perform continuous and real-time repeated monitoring and estimation). The system 10 includes an earthquake detection device 101 and a computing module 102 . The earthquake detection configuration 101 detects vibration waves PW1/PW2 at different locations in the same area. According to an embodiment, the earthquake detection configuration 101 includes a main sensor 1010 and an auxiliary sensor 1011 located at different detection points. Among them, the auxiliary sensors mentioned in this case can be designed to increase the decision-making accuracy of the earthquake detection system, and in some embodiments, they can also replace the main detector when the main detector fails. function.

Those skilled in the art understand that when an earthquake occurs, the main sensor 1010 and the auxiliary sensor 1011 configured in different locations in the same area will sense vibrations almost at the same time. The main sensor 1010 and the auxiliary sensor 1011 generate the first signal S1 and the second signal S2 respectively in response to the first vibration wave PW1 and the second vibration wave PW2 that appear in the first vibration event PM1 and the second vibration event PM2. . These signals are sent to the computing module 102 at the same time. The main sensor 1010 described here is mainly used to detect various vibrations caused by earthquakes, such as longitudinal waves or transverse waves, and the second signal S2 of the auxiliary sensor 1011 can be used to determine the main sensor. Whether the first vibration wave PW1 detected by the detector 1010 is generated by the same earthquake event. According to different embodiments, the auxiliary sensor 1011 may include a set of sensing elements (not shown), without departing from the scope of the invention.

According to an embodiment, the computing module 102 includes a judgment module 1021 and a prediction module 1022. The determination module 1021 receives the first and second signals S1/S2 and determines whether there is an earthquake event based on them. Professionals in this field can understand that when an earthquake occurs, the main sensor 1010 and the auxiliary sensor 1011 configured in different locations in the same area will almost sense vibrations with very similar time duration and magnitude at the same time, so comparing the first and The common correlation between the second signals S1/S2 can determine whether an earthquake has occurred. According to an embodiment of this invention, the first signal S1 is synchronously transmitted to the judgment module 1021 and the prediction module 1022, and the second signal S2 is transmitted to the judgment module 1021, so that these two modules with independent functions can execute their respective functions synchronously. task. According to an embodiment, the judgment module 1021 sends the earthquake event discrimination signal EEV2 to indicate whether there is an earthquake event. For example, the earthquake event discrimination signal EEV2 is 1, which means that the judgment result shows that there is an earthquake event. The judgment module 1021 provides real-time judgment of whether there is an earthquake event, which can avoid false alarms caused by erroneous messages.

The prediction module 1022 receives the first signal S1 and predicts the real-time seismic shear wave prediction characteristic value ESV2 of the upcoming seismic shear wave. According to an embodiment, the first signal S1 includes longitudinal wave acceleration data in various directions on the ground surface, such as acceleration data in at least one of the horizontal direction or the vertical direction, and the real-time seismic shear wave estimated characteristic value includes a maximum surface acceleration value and a maximum surface speed Magnitude value, this characteristic parameter is usually regarded as an important indicator for measuring earthquake intensity levels by various countries.

Referring again to the first figure, when the earthquake event identification signal EEV2 sent by the judgment module 1021 shows the existence of an earthquake event, the computing module 102 can send the real-time earthquake shear wave prediction characteristic value ESV2 to the preset unit to provide earthquake warning. Since the judgment module 1021 and the prediction module 1022 in the computing module 102 operate in parallel, earthquake warning information (such as real-time earthquake shear wave prediction characteristic value ESV2) can be provided to all units in the area in a short period of time. Carry out disaster prevention actions.

According to another point of view, refer to the second figure in conjunction with the first figure, which is an example of a method for judging earthquakes and predicting seismic wave intensity in a single step, including the following steps. When an earthquake or similar event occurs, the earthquake judgment method proposed in this creative embodiment can receive a first signal S1 generated in response to a first vibration event PM1 and a second signal S1 generated in response to a second vibration event PM2 through appropriate devices. a second signal S2 (step S203). It should be noted that the first and second signals S1/S2 come from earthquake detection devices at different locations and can detect vibration waves generated by earthquakes. If the first and second vibration events PM1/PM2 originate from earthquakes event, then the first and second signals S1/S2 measured by seismic detection devices at different locations should have similar properties, or in other words, the time and amplitude of the surface vibration should be have a close relationship. Therefore, this creative embodiment can determine whether there is an earthquake event based on the first and second signals S1/S2 (step S204). This way It can avoid the possibility of ordinary surface vibration events being misjudged as earthquakes or even triggering false alarms.

The method of determining the type of earthquake and estimating the intensity of seismic waves in this creative embodiment is to simultaneously determine whether it is an earthquake event and estimate the magnitude of the earthquake. That is, while performing step S204, the prediction module 1022 can be used to predict a real-time seismic shear wave prediction characteristic value ESV2 based on the first signal S1 (step S205), but is not limited to estimation based on the acceleration related parameters of the longitudinal wave. The maximum surface acceleration value caused by shear waves; when it is determined that there is an earthquake event using the method of step S204, the real-time earthquake shear wave estimated characteristic value ESV2 is immediately sent (step S206).

Since steps S204 and S205 operate synchronously, earthquake warning information (such as real-time seismic shear wave prediction characteristic value ESV2) can be provided immediately in a shorter time compared to the method of prediction and judgment performed one after another. All units in the area carry out disaster prevention actions. Moreover, no matter what the real-time seismic shear wave prediction characteristic value ESV2 estimated in step S205 is, if the judgment result in step S204 is not an earthquake event, the prediction value will not be sent to avoid triggering false alarms. Therefore, the overall comprehensiveness of the early warning system using this implementation method can also be effectively improved.

Please refer to the third figure, which reveals earthquake judgment 30, step 300: start. It means that after the system test is completed, each sensor and host (not shown in the third picture) are in a normal power-on and power-on state. Next, proceed to step 301: whether the main sensor and the remote signal source simultaneously allow the host to confirm that there is an earthquake. This step refers to a In the judgment step, if the main sensor and the remote signal source simultaneously confirm that there is an earthquake, then step 301Y is entered: judge that an earthquake has occurred and send an earthquake indication signal. And if the main sensor and the remote signal source do not simultaneously confirm that there is an earthquake in the host, then step 301N is entered: it is judged that the earthquake has not occurred, and no earthquake indication signal is transmitted. The simultaneous triggering described here essentially refers to triggering within a specific period of time. This specific period of time is six seconds and can also be longer or shorter. Furthermore, the remote signal source is connected to the host through the network and sends a remote signal to the host. If the remote signal source is an auxiliary sensor, the remote signal is a measurement value, and the measurement value is then calculated by the host to obtain an acceleration signal, a speed signal, or a displacement signal. And if the remote signal source is an auxiliary earthquake detection system, the remote signal is a trigger signal.

Please refer to the fourth figure, which is a schematic diagram of the combined configuration of the free field and the remote signal source and its earthquake detection system according to this embodiment of the invention. It can be seen that there are a total of two types of sensor settings and connection methods. First, the free field sensor FFS (main sensor) is installed in the free field FF (free field). The free field FF roughly includes the space within two meters from the surface to the ground for installation. In addition, A host M can be set up on the free field FF. The host also includes a computing unit, a transmission or communication interface, etc. (not shown in the figure). The host M can also be set up outdoors or in a structure in a protected field (in the figure) not revealed). Sensors are sometimes susceptible to interference from non-seismic and artificial vibrations, such as vibrations produced by rail vehicles. Generally, such vibrations have large amplitude, low frequency, and strong penetrating power. Therefore, it is difficult to avoid these interferences. The detector must be set far enough away, but due to the signal of the sensor The wire transmits analog signals, so the signal strength is greatly attenuated as the distance increases. Therefore, when the auxiliary sensor is set up at a distance of more than several hundred meters to avoid the above interference, it can The sensing signal of the auxiliary sensor is transmitted through the network to avoid being affected by the signal attenuation of the physical line.

Please continue to refer to Figure 4, in which the remote signal source can also be another earthquake detection system C-sys, that is, it has its own host as a remote system, that is, the remote signal source is used as a remote system. The remote seismic sensing signal source can come from a sensor, which is an auxiliary sensor relative to the local (current location); it can also come from an earthquake detection system, which is an auxiliary sensor relative to the local (current location). It is a remote auxiliary earthquake detection system C-sys. When the remote signal source is a remote auxiliary earthquake detection system C-sys, the remote signal transmitted externally is a trigger signal. The opportunity to use the remote signal source is if the area where the main sensor is installed is not deep enough, and the auxiliary sensor cannot be installed at a slightly farther horizontal distance, or the deep well sensor cannot be installed, in case the field is protected. There are vibration sources within artificial structures that can cause vibrations. For example, the rail vehicle in this case cannot use structural sensors. In particular, structural sensors cannot be installed on elevated tracks or tunnel structures. If the above-mentioned unsuitable In places, you can use remote signal sources.

In addition, the remote signal source can be used as a backup when other sensors are seriously interfered by noise. As shown in the fourth figure, rail vehicles on the surface or underground sometimes produce relatively low-frequency vibrations with strong penetrating power and long distances. Therefore, even if a deep well sensor is used, it may still be seriously interfered by noise and the sensor will be affected. Therefore, in addition to the main sensor FFS according to the general settings, it is more appropriate to use a remote signal source. In short, the characteristic of the remote signal source in this case is long-distance transmission through the Internet. Features, widen the distance between each auxiliary sensor or auxiliary detection system (remote auxiliary earthquake detection system C-sys) and the local main sensor of the system, and can communicate with the local main sensor through the Internet The host M is connected to achieve the effect of checking whether an earthquake has occurred. Furthermore, the remote auxiliary earthquake detection system C-sys is a local system for itself, so it can also have its own remote signal source.

Please refer to Figure 5, which is a schematic diagram of another embodiment of the combined configuration of the creative free field and the remote signal source and its earthquake detection system. It is disclosed that a first auxiliary sensor SS1, a second auxiliary sensor SS2, a third auxiliary sensor SS3, a fourth auxiliary sensor SS4, and even the n-th auxiliary sensor SSn all pass Network connection to local host M. A main sensor FFS is also set up locally on the free field, which can be on the surface or within two meters below the surface. Regarding the embodiment in Figure 5, it can be understood that each auxiliary sensor is a separate device, that is, a remote signal source that transmits earthquake sensing results to the local (current) host M through the network. When there are multiple remote signal sources, it means that these signal sources are set remotely relative to the main sensor, in other words, they are set at the remote end, but the plurality of signal sources can be the same remote source. Within the field, it can also be in a different field at the far end. That is to say, the far end is a long-distance concept, which means that the far-end signal source is far away from the main sensor. When the remote signal source is an auxiliary sensor, the remote signal transmitted externally The signal is a measurement value. After calculation by the host, an acceleration signal, a speed signal, or a displacement signal can be obtained. In addition, if the remote signal source has a calculation function, it can first convert the measured value into an acceleration signal, or a velocity signal, or a displacement signal, or two of them, or all three, and then send it back through the network. host.

Please refer to the sixth figure, which shows earthquake determination 60, step 600: start. It means that after the system test is completed, each sensor and host (not shown in the sixth picture) are in a normal power-on and power-on state. Next, step 601 is performed: whether the main sensor, the plurality of auxiliary sensors, and the remote signal source simultaneously confirm that there is an earthquake. This step refers to a judgment step. If the main sensor, each of the plurality of auxiliary sensors, and the remote signal source all simultaneously confirm that there is an earthquake, then step 601Y is entered: judge that an earthquake has occurred and send an earthquake indication signal. . And if the main sensor, auxiliary sensor, and remote signal source do not simultaneously confirm the host that there is an earthquake, then step 601N is entered: it is determined that an earthquake has not occurred, and no earthquake indication signal is transmitted. The simultaneous triggering described here essentially refers to triggering within a specific period of time. This specific period of time is six seconds, or it can be shorter. Furthermore, the remote signal source is connected to the host through the network and sends a remote signal to the host. If the remote signal source is an auxiliary sensor, the remote signal is selected from an acceleration signal, a velocity signal, or a displacement signal. And if the remote signal source is an auxiliary earthquake detection system, the remote signal is a trigger signal.

Please refer to the seventh figure, which is the combined configuration of free field, structure and deep well sensors and remote signal source DS and its earthquake detection system according to this embodiment of the invention. schematic diagram. It can be seen that there are a total of four types of sensor settings and connection methods. First, the main sensor FFS (free field sensor) is set up in the free field (free field, which refers to the surface of the earth or very close to the earth's surface). The free field roughly includes the surface of the earth to within two meters below the earth's surface. The host M of this creative embodiment is located on the free field FF, and the main sensor FFS is located next to the host M and connected to the host M through a physical line. The host also includes a computing unit, a transmission or communication interface, etc. (not shown in the picture). Generally speaking, in order to facilitate adjustment and maintenance, the host M and the main sensor FFS will be placed on the surface. As for the main sensor FFS that is within two meters below the surface, it is called a shallow well sensor. The purpose of using shallow well is Sometimes the ground surface is easily disturbed by inappropriate external forces. For example, if you are on the side of a school sports field, you may often be disturbed by balls and sports equipment, which increases the probability of misjudgment by the sensor. Therefore, you must avoid these interferences, but because you cannot be at a distance, The surface FF is too deep and the cost is too high, so the main sensor FFS can be set at a maximum depth of about two meters underground to avoid high construction costs and increase the difficulty of maintenance and adjustment. In addition, the host M can also be installed in a structure in a protected area, such as a school, a residence, a commercial building, etc. indoors. Furthermore, in order to avoid interference from human activities such as buildings, the horizontal distance between the free field sensor FFS and the structures and artificial structures in the protected area is at least ten meters, preferably thirty meters. farther.

Please continue to refer to Figure 7, which also reveals a deep well sensor US1 located in a deep well. The depth D of the deep well in this embodiment is approximately twenty meters, and can reach a depth of fifty meters if circumstances permit. The reason for setting up the deep well sensor US1 is to keep it away from artificial vibration sources such as roads at a vertical distance. Because the hinterland of the protected area is often insufficient, the horizontal distance between the main sensor FFS and various buildings and structures in the protected area is short, so it is often interfered by vehicles passing on the road. In addition, in order to save costs, the depth D of deep wells is mostly within fifty meters. However, due to the influence of geology, if the rock pan is located at a higher level, less than fifty meters deep, or even less than twenty meters deep, the deep well sensor US1 is directly installed on the rock pan.

Please continue to refer to the seventh figure, which also reveals a structural sensor SCS1 located on the structure SC. Generally speaking, it is arranged on the beams, columns, or the joints of beams and columns of the structure SC. This is to allow shock waves to pass through the beams. The column system is transmitted to the structure sensor SCS1. If there are no machines or equipment that produce huge vibrations in the building, the amplitude of the vibrations generated by humans themselves is limited, or the vibrations generated when moving furniture and electrical equipment are larger than when humans walk, run, or jump, but Basically, it will not be transmitted outside the building and trigger the free field sensor FFS. As for the vibration amplitude of the compressor of refrigeration and air-conditioning equipment, the vibration amplitude is also small, and usually the machine itself has shock-absorbing pads that can greatly reduce the vibration transmission. The vibration mode is quite fixed and can be eliminated by the system of this creative embodiment, so it will not cause interference to the structure sensor SCS1, such as a building in a dense area of administrative agencies and financial institutions that this creative embodiment can be applied to. structure, the structure sensor SCS1 can be used. In addition, in order to further avoid human interference, the structure sensor SCS1 can also be arranged on the top of the structure SC, such as the roof, preferably, it is arranged on the top of the column.

Please continue to Figure 7, which reveals the remote signal source DS can include one or more remote sensors as auxiliary sensors. The horizontal distance from the protected object may be from tens to hundreds of meters, or even three or four kilometers away. , and the remote signal source DS can also be another earthquake detection system as a remote auxiliary earthquake detection system, that is, it has a host itself as a remote system, and communicates with this creative embodiment through the Internet The host connection, that is, the remote signal source DS is used as an earthquake sensing signal source from a distance. It can come from the sensor, which is an auxiliary sensor relative to the local one; it can also come from a The earthquake detection system is a remote auxiliary earthquake detection system relative to the current site. The opportunity to use the remote signal source DS is if the hinterland of the protected field is not enough, the auxiliary sensor cannot be set up at a far enough horizontal distance, or the structure sensor SCS1 is often interfered with, or the deep well sensor US1 If the depth is less than 20 meters and there are the above unsuitable places, you can use the remote signal source DS. When there are multiple remote signal sources, it means that these signal sources are set remotely relative to the main sensor, in other words, they are set at the remote end, but the plurality of signal sources can be the same remote source. Within the field, it can also be in a different field at the far end. That is to say, the far end is a long-distance concept, which means that the far-end signal source is far away from the main sensor. If this creative embodiment is applied to buildings in densely populated areas such as administrative agencies and financial institutions, since there are fewer devices that can produce severe vibrations inside such structures, the structure sensor SCS1 can be used. The purpose of using the deep well sensor US1 is to avoid vibration interference from large and heavy vehicles, and the main sensor FFS can be used as the set point of the host. In addition, through the remote signal The source DS can be used as a backup in case the other sensors fail. It can be seen that the structure sensor SCS1, the deep well sensor US1, and the remote signal source DS are all auxiliary sensors. Therefore, when each auxiliary sensor and the main sensor both determine that there is When an earthquake occurs, the host computer sends an earthquake alarm.

To sum up, this case provides an innovative concept that allows when an earthquake occurs, the seismic shear wave prediction characteristic values can be predicted instantly and reliably by on-site earthquake prediction technology based on real-time longitudinal wave measurement data, thereby providing the basis for the strain. need. In addition, this case uses various sensors with different configurations to assist in determining whether an earthquake has occurred. If the hinterland is large enough, the auxiliary sensors can be placed at a longer horizontal distance. If there are vibration sources that produce large-scale noise, such as structures such as tracks, heavy industrial factories, mines, and waterfalls, they can be supplemented by remote signal sources to more effectively stay away from various interferences. When a vibration occurs At the time of the event, if the local main sensor, the remote auxiliary sensor, or the auxiliary earthquake detection system C-sys all believe that the vibration event is an earthquake within a specific period of time, the local host will send out an earthquake Warning, through the configuration of various earthquake sensors in this case, the accuracy of earthquake judgment can be higher, and a plurality of suitable remote auxiliary sensors can be provided to form a configuration according to the restrictions of the location of the main sensor. When the misjudgment rate of earthquakes is reduced, work stoppages caused by misjudgments will be reduced, thereby reducing delays or waste caused by work stoppages and material stops. For rail facilities, it can also reduce time costs caused by stoppages and speed reductions. In other words, if the misjudgment rate decreases, the number of evacuation measures taken due to misjudgment will decrease, and the losses caused by these evacuation measures will also decrease. This case Various different configurations of sensors are also used to assist in determining whether an earthquake has occurred. Of course, in this case, the "combination configuration of free field, structural and deep well sensors and remote signal sources and their earthquake detection system" are used For buildings in densely populated areas of administrative agencies and financial institutions, it is indeed worthy of sufficient budget to provide protection and early warning. The protected objects can be protected in as many configurations as possible. When one of the auxiliary sensors When there is a fault or the connection is unavailable, the remaining function can still be used to verify whether an earthquake has occurred. Generally speaking, if the hinterland is large enough, the main sensor can be placed at a farther horizontal distance. If there will be interference from vehicles near a structure, deep well sensors can be installed to move away from interference over a longer vertical distance. If there is no machinery inside the structure that will produce vibrations, structural sensors can be installed. In addition, the use of remote signal sources can more effectively keep away from various interferences. Through the configuration of various earthquake sensors in this case, the false positive rate of earthquake prediction can be further reduced, and the misjudgment rate of earthquake prediction can be further reduced according to the protected field. The limitations provide a suitable plurality of sensors to form a configuration and avoid being unable to provide service due to the failure of any one sensor. Furthermore, because the misjudgment rate is reduced, it can reduce the economic losses caused by work stoppages due to misjudgment, and also reduce the inconvenience and false alarm caused by taking evacuation measures due to misjudgment, thereby improving the quality of life. In other words, the misjudgment rate If it decreases, the number of evacuation measures taken due to misjudgment will be reduced, and the losses caused by these evacuation measures will also be reduced. It can be seen that this case has made a great contribution to related industries.
