Description

Combinations of free field, structure sensors and remote signal sources and their earthquake detection system

This work is about earthquake detection; especially about earthquake detection methods and devices using multiple sensors, especially those used in transportation facilities such as port stations, as well as in areas filled with financial centers and high-rise buildings. Earthquake detection systems and their networks.

Among all natural disasters, "earthquakes" are considered to be quite terrifying, because most other disasters such as typhoons, volcanic eruptions, etc. can be predicted very early in advance, from hours to days. However, the occurrence of earthquakes is unpredictable because there are no signs before an earthquake occurs. However, even at the beginning of an earthquake, prediction and prevention can still be made to a certain extent, because the speed of seismic waves can be divided into "P waves" and "S waves" from fast to slow. 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, seismometers can be used to sense seismic waves to provide early warning, issue warnings and take measures before serious disasters occur. move. The specific prediction method is to use the P wave's fastest wave speed and earliest arrival characteristics to predict the early warning of S waves and surface waves arriving 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 sensors often misjudge earthquakes due to surface vibrations caused by human activities (such as people running, vehicles passing by, construction sites, heavy industrial factories). Therefore, how to prevent unnatural factors from triggering the seismometer and misidentifying it as an earthquake 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 auxiliary sensing signals, 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, the solution is to use a single threshold judgment method. When there are several types of unnatural vibrations in the field, this method is Easy to misjudge.

Therefore, the main purpose of this invention is to provide an earthquake detection system to carry out special planning for various places that need to be protected. To this end, the applicant has worked hard and proposed the "free field and structure sensor" of this invention. and a combination of remote signal sources and its earthquake detection system" to avoid misjudgments caused by unnatural surface vibrations and improve the accuracy of earthquake judgments.

In order to prevent unnatural factors from causing misjudgments by seismometers and prevent vibrations caused by human activities from interfering with seismometers and seismic sensors, this creation achieves verification by installing multiple sensors at different locations. As a result, an earthquake warning will be issued to the protected location only when all sensors confirm that there is an earthquake. By setting up sensors in three different environments, it is possible to prevent two sensors from being misjudged at the same time due to the same interference that they may receive in the same environment. The "combination of free field, structure sensor and remote signal source and its earthquake detection system" of this creation further refers to the buildings that are used in non-factories and non-factory areas but as port stations, such as bus stations, Rail stations, ports, airports and other similar environments are characterized by a large number of people, and there will also be vibration interference from transportation and handling machinery such as cranes. In other words, for such environments, the sensing Optimize the configuration of the detector setting position to fully achieve accurate detection. In addition to setting up a free field sensor on the free field, this creation also sets up a structure sensor on a structure. Although the port station may be interfered by traffic, due to its relatively simple measurement The track is much larger, that is, its inertia is larger, so it can usually absorb most of the vibrations from the vehicle, and after Proper design can also isolate rail vehicle vibrations from structural sensors. In addition, the structure sensor of this invention is also suitable for some factories, factory areas, and even financial buildings, residences, office buildings, schools, medical institutions and other related structures and areas filled with high-rise buildings, as long as it is not It is enough that there will be large-scale, regular violent vibrations. If the hinterland of these structures is too small and the geological conditions are poor to set the deep well sensor deep enough, a remote signal source can be used to assist in the review. Whether an earthquake occurs. In addition, just in case, this creation uses a remote signal source to reduce misjudgments in local earthquake detection, that is, only local free-field sensors, structure sensors, and remote signal sources When all three of them believe that there is an earthquake, the host will send out an earthquake alarm. Or the structure sensor and the remote signal source support each other. If one of them fails or loses connection, the other one can still perform the function of sensing earthquakes and cooperate with the main sensor to Check whether the earthquake occurred within the same specific time period. The review of the main sensor through structure sensors and/or remote signal sources can more effectively reduce misjudgments of earthquakes, thereby reducing the losses caused by similar shutdowns and shutdowns due to misjudgments. In addition, due to This creation reduces the misjudgment of earthquakes, and people's lives will not be interrupted by false earthquake warnings. This means that there is no need to take evacuation actions, and vehicles do not need to slow down or stop, so it can improve the quality of life.

Therefore, in order to achieve the above purpose, this invention provides an earthquake detection system that is a combination of free field, structure sensor and remote signal source, including: a host; a main sensor, which is set in a free field and connected to the host; an auxiliary sensor is provided on a structure and connected to the host; and A remote signal source is a signal source that is installed at a remote site and outputs a remote signal through an Internet.

In order to achieve the above purpose, this invention further provides a combined configuration of free field, structure sensor and remote signal source used in an earthquake detection system, including: a main sensor, arranged in a free field As a free field sensor; a first auxiliary sensor, disposed on a structure; and a second auxiliary sensor, disposed at a remote end relative to the main sensor, wherein the second The auxiliary sensor outputs a remote signal through an Internet, wherein the sensing signals sent by the main sensor and the first auxiliary sensor, and the remote signal all arrive at the same receiving device. The receiving device is usually a host.

The above objects and advantages of the present invention will become more immediately apparent to those with ordinary knowledge in the art after referring to the following detailed description and accompanying drawings.

[Figure 1] is the earthquake judgment block diagram of this creation.

[Figure 2] is the combination of free field, structure sensor and remote signal source of this invention. Schematic diagram of the combined configuration and its earthquake detection system.

Please refer to Figure 1, which illustrates earthquake determination 10, step 100: start. It refers to the processing of each sensor and host (not shown in Figure 1) after the system test is completed. In the normal boot and power-on state. Next, step 101 is performed: whether the main sensor, the auxiliary sensor, and the remote signal source simultaneously confirm that there is an earthquake. This step refers to a judgment step. If the main sensor, the auxiliary sensor, and the remote signal source all simultaneously confirm that there is an earthquake, then step 101Y is entered: judge that an earthquake has occurred and send an earthquake indication signal. And if the main sensor, the auxiliary sensor, and the remote signal source do not simultaneously cause the host to confirm that there is an earthquake, then step 101N is entered: it is determined 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, 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 a measurement value. Furthermore, the measurement value 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 Figure 2, which is a schematic diagram of the combined configuration of the free field, structure sensor and remote signal source of this creation. It can be seen that there are a total of three 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 or very close to the surface). The free field roughly includes the area from the surface to within two meters below the surface. Space, the host M can also be set on the free field FF, and the main sensor FFS is set next to it and connected to the host M through a physical line. In order to facilitate adjustment and maintenance, the main unit M and the main sensor will be set on the ground. If it is on the side of the school sports field, it may often be interfered by balls and sports equipment. In order to avoid the interference of human activities in the protected field To prevent interference, the horizontal distance between the free field sensor FFS and the structures in the protected area is at least ten meters, preferably thirty meters, and can be further. In addition, the host M can also be installed in a structure S in the current site, such as a residence, a medical institution, a transportation-related building, a factory, an office building, or a factory-office integrated building.

Please continue to refer to Figure 2, which also reveals a structure sensor S1 located on the structure S. Generally speaking, it is disposed on the beams, columns, or the joints of beams and columns of the structure S. This is for the purpose of shock wave energy. It is transmitted to the structure sensor S1 via the beam-column system. If there are no machines or equipment that produce huge vibrations in the building, the vibrations generated by humans themselves, such as when carrying luggage, walking, running, and jumping, have extremely limited amplitudes and are basically impossible to spread outside the building. Triggering the free field sensor FFS, the vibration amplitude of the compressor of the refrigeration and air-conditioning equipment is also small, and usually the machine itself has shock-absorbing pads that can greatly reduce the vibration transmission, and the vibration pattern is quite fixed and can also be modified by this invention If the system excludes structures such as bus stations, train stations, ports, and airport waiting rooms, the structure sensor S1 can be used. Since the overall structure of the structure S used as the track station is relatively large, it is less likely to be vibrated by the train than a simple track. Moreover, through appropriate structural design, the vibration caused by the track can be greatly reduced. Structure sensor S1 can therefore be used. In addition, in order to further avoid human interference, the structure sensor S1 can also be arranged on the top of the structure S, such as the roof, preferably, it is arranged on the top of the column.

Please continue to refer to Figure 2, which reveals the remote signal source C-SYS, which can include one or more remote signal sources as auxiliary sensors. Its horizontal distance from the protected object may be from tens to hundreds of meters, or even three or four kilometers away, and the so-called remote signal source C-SYS can also be another earthquake detection system, that is It has a host itself as a remote system relative to the local area, and is connected to the host M of this creation through the Internet, that is, the remote signal source C-SYS serves as an earthquake sensing signal from a distance The source can come from a sensor, which is an auxiliary sensor relative to the current location; it can also come from an earthquake detection system, which is a remote auxiliary earthquake detection system relative to the current location. The host M can be set on the free field FF, or within a structure in the protected field. The opportunity to use the remote signal source C-SYS is if the hinterland of the protected field is not enough, so that the free field sensor FFS lacks sufficient horizontal distance to be set away from the interference source in the protected field, or the geological conditions The deep well sensor U1 cannot be installed due to restrictions. Although the structure sensor S1 is already installed on the structure S, if there are the above restrictions, the remote signal source C-SYS can be used. For example, in a rail station, these sensors can be used at the same time to avoid misjudgments caused by the vibration of rail vehicles interfering with the structure sensor S1 and the free field sensor FFS. Furthermore, when the remote signal source, the auxiliary sensor, and the main sensor all believe that there is an earthquake, the host also believes that there is an earthquake. In addition, the remote signal source C-SYS can be used as a backup in case other sensors fail. 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 at the remote end. In the same 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 refers to the remote information Source The signal source is far away from the main sensor. In addition, when the remote signal source is an auxiliary sensor, the remote signal is a measurement value. Furthermore, the measured value is selected from an acceleration signal, a velocity signal, or a displacement signal. Usually, after the measured value is transmitted to the host, the host converts it into these three signals. However, if the auxiliary sensor If the detector has calculation or conversion functions, it can also select one, two, or all of the three signals generated after conversion and send them to the host. Also, when the remote signal source is an auxiliary earthquake detection system, the remote signal is a trigger signal.

To sum up, this creation uses various different configurations of sensors to achieve the effect of assisting in determining whether an earthquake has occurred. Of course, if there is enough budget, the protected object can be protected in as many configurations as possible. Generally speaking, if the hinterland is large enough, the main sensor can be placed at a farther horizontal distance. If there is machinery in the structure that will produce vibrations, or if the structure is nearby and will be disturbed by vehicles, deep well sensors can be installed to keep away from the interference through a longer vertical distance. If there are no major sources of vibration in structures such as residences, schools, and medical institutions, or factories that do not have large-scale vibrations, or the port station is large enough to avoid vibrations from vehicles through appropriate design If there is interference, you can set up a structure sensor. In addition, supplemented by the remote signal source C-SYS, it can more effectively stay away from various interferences to reduce misjudgments of earthquakes. That is, there are only three main sensors, structure sensors, and remote signal sources. Only when it is believed that there is an earthquake within a specific period of time, this creation will make a judgment that there is indeed an earthquake, such as issuing an earthquake warning, etc. In addition, the structure sensor and the remote signal source can also support each other. If one of the sensors fails or cannot be connected, the remaining auxiliary sensors can still review whether the earthquake judgment of the main sensor is correct, thereby significantly reducing earthquake misjudgments. Through the various configuration methods of seismic sensors in this creation, the accuracy of earthquake prediction can be higher, and a suitable plurality of sensors can be provided to form a configuration according to the restrictions of the protected area. When the misjudgment rate of earthquakes is reduced, Then the stoppages caused by misjudgments will be reduced, thereby reducing delays or waste caused by stoppages of work and materials. In addition, because this creation reduces misjudgments of earthquakes, people's lives will not be stagnated by false earthquake warnings ( That is, there is no need to take evacuation actions), and the rail vehicles will not slow down or stop causing time delays, so the quality of life can be improved. In other words, the misjudgment rate is reduced, and the evacuation measures taken due to misjudgment will be reduced. Because of these evacuation Losses caused by measures will also be reduced. It can be seen that this creation has a great contribution to related industries.
