Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 3, an impending earthquake prediction method for a building according to an embodiment of the present invention includes:
and S01, determining the flow path of the personnel in the target building.
The flow path of the personnel in the target building can be determined through the monitoring video in the target building.
And S02, selecting the position where no person flows in the target building as the earthquake monitoring position based on the person flow route.
When a person walks or works near an earthquake monitoring place, vibration signals generated on the ground can interfere with the accuracy of impending earthquake forecast information acquired by monitoring the vibration signals transmitted from the ground at the earthquake monitoring place, so that a position where no person flows in a target building needs to be selected as the earthquake monitoring place.
In another embodiment, an impending earthquake prediction method for a building provided by an embodiment of the present invention includes: and determining the flow route of the personnel or the vehicles around the target building, and selecting the position without the flow of the selected personnel or vehicles around the target building as the earthquake monitoring position based on the flow route of the personnel or the vehicles around the target building. For example, when the target building is located in a suburban area or an isolated area, the personnel flow rate around the target building is smaller than that in the target building, and at the moment, an earthquake monitoring place is arranged around the target building, so that the probability of the false alarm of the imminent earthquake forecast information can be reduced.
S03, installing an earthquake monitoring device at the earthquake monitoring place, wherein the earthquake monitoring device is used for monitoring a vibration signal at the earthquake monitoring place and sending first early warning information to a server when the amplitude of the vibration signal is not less than a preset amplitude threshold value.
The preset amplitude threshold value can be specifically set according to the earthquake-proof grade of the target building, namely when the earthquake monitoring device is applied to different buildings, the preset amplitude threshold value is independently set.
The first early warning information is used for determining whether an earthquake is imminent.
The seismic monitoring device may monitor a vibration signal at a seismic monitoring location, and acquire, store, and process the monitored vibration signal, for example, obtain an amplitude of the monitored vibration signal, and compare the obtained amplitude of the monitored vibration signal with a preset amplitude threshold.
The control module can be arranged in the earthquake monitoring device, the regular expression is used for processing the comparison result between the amplitude of the vibration signal and the preset amplitude threshold value through the control module, and first early warning information is sent to the server when the amplitude of the vibration signal is not smaller than the preset amplitude threshold value.
S04, if the server receives first early warning information sent by more than a preset number of earthquake monitoring devices at the same time, sending second early warning information to an alarm module and/or a shockproof device; the server is in communication connection with the alarm module and/or the anti-seismic device, and the second early warning information is used for early warning whether the earthquake occurs at the location of the building.
In the same way, the regular expression can be used for processing the number of the received first early warning messages and sending second early warning messages to the alarm module and/or the shockproof device, so that the server sends the second early warning messages to the alarm module and/or the shockproof device after receiving the first early warning messages with the number exceeding the preset number at the same time.
The alarm module and the shockproof device can be provided with network communication modules, or the alarm module and the shockproof device are respectively connected with the server through optical fibers or network cables, so that the server is in communication connection with the alarm module and/or the shockproof device. After receiving the second warning information, the warning module may send a warning signal, for example, the warning module sends a buzzer sound and/or sends a flashing light with a preset frequency. The shock protection device may be activated directly after receiving the second warning message, for example by presetting the rate at which the airbag inflates to wrap a target object within the target building.
According to the imminent earthquake prediction method for the building, provided by the embodiment of the invention, the position where no person flows in the target building is selected as the earthquake monitoring position by determining the flow path of the person in the target building, so that the imminent earthquake prediction information is prevented from being mistakenly reported when a vibration signal generated by the person during walking or working is transmitted to the earthquake monitoring position, and when the first early warning information exceeding the preset number is received, the imminent earthquake is determined to be imminent, so that the imminent earthquake prediction information is further prevented from being mistakenly reported. The earthquake forecasting method for the impending earthquake of the building can provide longer protection preparation time, is more targeted, and can protect the building structure more effectively.
In order to reduce the probability of false alarm of imminent earthquake prediction information, in one embodiment, based on the personnel flow route, a position where no personnel flow is selected as an earthquake monitoring position includes: selecting at least two positions where no personnel flow and a stable building structure are located as earthquake monitoring positions based on personnel flow routes; wherein the distance between at least two positions where no person flows and the building structure is stable is not less than the preset distance.
It can be understood that the earthquake monitoring places are arranged at one place, but the more the number of the earthquake monitoring places is, the higher the accuracy of the issued imminent earthquake early warning information is. The preset distance refers to a distance that a vibration signal generated when a person walks, jumps or works in a personnel flow path cannot simultaneously influence two earthquake monitoring places and a vibration signal generated when a vehicle passes by near a target building cannot simultaneously influence the two earthquake monitoring places. The location having a stable building structure that facilitates the transmission of the vibration signal from the surface to the seismic monitoring device may be selected as the seismic monitoring site on a structure such as concrete that satisfies the conditions.
Although the seismic survey is selected to be a location where no human flow is present, there is still a possibility that the seismic survey receives interfering vibration signals. For example, a vibration signal generated by a vehicle passing near a target building or a large vibration signal generated by an accident near the target building may be transmitted to an earthquake monitoring place, so that the imminent earthquake prediction information is mistakenly reported. In the application, the probability of the false alarm of the impending earthquake prediction information can be reduced to a certain extent by arranging at least two earthquake monitoring places at a preset distance.
For example, referring to fig. 2, on a multi-story museum building structure, a first earthquake monitoring site 201 may be selected on the second story of the museum building structure, a second earthquake monitoring site 202 and a third earthquake monitoring site 203 may be selected on the roof of the museum building structure, and the distances between the three earthquake monitoring sites may be respectively not less than a preset distance. If the first seismic surveillance site 201 of the museum building structure detects a vibration signal generated by the jumping of a person and transmits first warning information to the server, but because the distance between the first seismic site 201 on the second floor of the museum building structure and the second and third seismic sites 202 and 203 on the roof of the museum building structure is outside the distance simultaneously affected by the vibration signal generated by the bouncing of people, the vibration signal generated by the jumping of people cannot be simultaneously monitored by the first seismic surveillance site 201, the second seismic surveillance site 202 and the third seismic surveillance site 203 of the building structure of the museum, that is, the first earthquake monitoring department 201, the second earthquake monitoring department 202 and the third earthquake monitoring department 203 of the building structure of the museum do not simultaneously send the first early warning information to the server, therefore, the server can determine that the first early warning information sent by the first earthquake monitoring place 201 on the second floor of the building structure of the museum is the interference early warning information.
The number and the position of earthquake monitoring places and the installation position of an earthquake monitoring device of the impending earthquake forecasting method for the building provided by the embodiment of the invention are relatively flexible, and in one embodiment, the positions which have no personnel flow and have stable building structures comprise: basements, ceilings, piping shafts, and top corners in buildings. Namely, when selecting the earthquake monitoring place, the man-made interference needs to be avoided as much as possible.
It will be appreciated that the above-described basements, attics, piping shafts, and top corners in buildings are merely examples of locations where no personnel are moving, having a stable building structure, and are not intended as limitations on the scope of locations where no personnel are moving, having a stable building structure.
In one embodiment, a seismic monitoring device is installed at a seismic monitoring site, comprising: installing a vibration sensor of an earthquake monitoring device at the earthquake monitoring position so that the vibration sensor monitors a vibration signal at the earthquake monitoring position; connecting a data acquisition card of the earthquake monitoring device with a vibration sensor so that the data acquisition card receives a vibration signal sent by the vibration sensor, processing the vibration signal to acquire the amplitude of the vibration signal, and comparing the amplitude of the vibration signal with a preset amplitude threshold value; and connecting the server with a data acquisition card of the earthquake monitoring device through a remote network, and if the amplitude of the vibration signal is not less than a preset amplitude threshold value, sending first early warning information to the server by the data acquisition card.
Referring to fig. 3, the seismic monitoring device may include a first seismic monitoring device 101, a second seismic monitoring device 102, and a third seismic monitoring device 103, where the first seismic monitoring device 101 includes a first data acquisition card 1011 and a first vibration sensor 1012, the second seismic monitoring device 102 includes a second data acquisition card 1021 and a second vibration sensor 1022, the third seismic monitoring device 103 includes a third data acquisition card 1031 and a third vibration sensor 1032, and the first data acquisition card 1011, the second data acquisition card 1021, and the third data acquisition card 1031 are respectively connected to a server through a remote network.
As mentioned above, the earthquake monitoring place can be selected from concrete structures meeting the conditions, and at this time, the earthquake monitoring device can be installed at the earthquake monitoring place by using expansion bolts to monitor the vibration signals of the earthquake monitoring place, and preferably, the earthquake monitoring device is installed at the earthquake monitoring place to monitor the longitudinal vibration signals of the earthquake monitoring place. The data acquisition card is integrally connected with the vibration sensor or is connected with the vibration sensor through a cable, when the data acquisition card is connected with the vibration sensor through the cable, one end of the cable can be connected with the vibration sensor, the other end of the cable is connected with the data acquisition card through a wiring board, and a lightning protection module is arranged between the wiring board and the data acquisition card to ensure the reliability of the connection between the data acquisition card and the vibration sensor.
When the amplitude of the vibration signal is not smaller than a preset amplitude threshold value, the earthquake monitoring device starts to store and process the monitored vibration signal and sends the processed vibration signal to the server. Specifically, the vibration sensor is configured to detect a vibration signal and send the detected vibration signal to the data acquisition card, the data acquisition card is configured to process the vibration signal and determine an amplitude of the vibration signal, and when it is determined that the amplitude of the vibration signal sent by the vibration sensor is not less than a preset amplitude threshold, the data acquisition card starts to send first warning information to the server, where the first warning information may include a switching value signal 0 or 1. Because the data volume of the switching value signal is extremely small, and the network delay is low, the first early warning information can be ensured to be sent to the server in time.
In order to facilitate the server side to analyze the vibration signals, a storage card is arranged in the earthquake monitoring device and used for storing the vibration signals of which the amplitudes collected by the vibration sensors are not less than a preset amplitude threshold value; after the seismic monitoring device is transmitting first warning information to the server, the method further comprises: and sending the vibration signal in the memory card to the server. The sending of the vibration signal in the memory card to the server may be immediately sending the vibration signal in the memory card after the first warning information is sent, or may be sending the vibration signal in the memory card after a preset interval.
In one embodiment, the network connection of the server to the data acquisition card of the seismic monitoring device comprises: the data acquisition card is provided with a mobile communication module and is connected with the server remote network through the mobile communication module, or the data acquisition card is connected with gateway equipment and is connected with the server remote network through the gateway equipment.
The mobile communication module may be a 3G module, a 4G module, or a 5G module. The gateway device may be a network router, wherein the data acquisition card is connected to the gateway device, or the data acquisition card may be connected to the network router via a cable. The server may be a cloud server.
The cloud server (also called a computing unit) is a computing service which is simple, efficient, safe and reliable, has elastically-telescopic processing capacity and has the characteristic of convenient management. The cloud server can be used for judging whether an earthquake is coming after receiving signals transmitted by the data acquisition card, sending imminent earthquake prediction information in a short message, broadcast or other form, or directly sending second early warning information to the anti-seismic device, so that the anti-seismic device can be directly started, for example, a preset air bag is inflated at a preset speed to wrap a target object in a target building.
The earthquake monitoring device and the server transmit signals through network signals, so that the server can be helped to quickly judge whether an earthquake is imminent, and longer protection preparation time can be provided to help effectively protect the building structure. It can be understood that the data acquisition card and the server can also be electrically connected through an optical fiber and the like to realize remote network connection.
The earthquake monitoring device can be connected with an external power supply, the external power supply can be industrial, civil or solar power supply, and a battery can be arranged on the earthquake monitoring device and supplies power to the earthquake monitoring device through the battery.
But it is preferred, link to each other seismic monitoring device with external power supply, because compare in through the battery to the seismic monitoring device power supply, can ensure through external power supply to the seismic monitoring device power supply can ensure that seismic monitoring device can not lead to avoiding the missing report of imminent earthquake early warning information because of lacking the vibration signal of seismic monitoring department of power supply, and then guarantee seismic monitoring device operational reliability.
In one embodiment, the network connection of the server to the data acquisition card of the seismic monitoring device comprises: and when the earthquake monitoring place is a closed environment, a signal amplifier is arranged in a preset range of the earthquake monitoring place and used for connecting the data acquisition card with the server through a remote network.
The preset range of the earthquake monitoring position is the installation range of the signal amplifier determined by field installation personnel according to the coverage range of the signal amplifier, the construction conditions of the earthquake monitoring position and the nearby structure and other specific factors. The signal amplifier is used for connecting the data acquisition card with the server remote network, and specifically, the mobile communication module on the data acquisition card is connected with the server remote network under the action of the signal amplifier, or the gateway device connected with the data acquisition card is connected with the server remote network under the action of the signal amplifier.
It will be appreciated that the seismic site may be located in a closed environment to avoid interference with the seismic site from vibration signals generated by people walking, bouncing, or other factors in the vicinity of the seismic site, for example, in a basement or in a pipe well; the data acquisition card is mainly used for storing and processing the vibration signals, sent by the vibration sensor, of which the amplitude is not less than a preset amplitude threshold value, and sending first early warning information to the server. Therefore, in order to ensure the reliability of the work of the earthquake monitoring device, the network signal of the data acquisition card is ensured to be good, and the signal test between the data acquisition card and the server is ensured to be normal. When the earthquake monitoring position is arranged in a closed environment and the data acquisition card is in wireless network connection with the server, the unstable connection condition may occur, and at the moment, the stability of the remote network connection between the data acquisition card and the server can be ensured by additionally arranging the network signal amplifier, so that the report missing of the impending earthquake early warning information is avoided, and the working reliability of the earthquake monitoring device is further ensured.
In one embodiment, the connecting the server with the alarm module and/or the anti-vibration device, and if the server receives first warning information sent by more than a preset number of earthquake monitoring devices at the same time, sending second warning information to the alarm module and/or the anti-vibration device includes: if the server receives first early warning information sent by all the earthquake monitoring devices at the same time, second early warning information is sent to the warning module and/or the anti-seismic device; or if the server receives the first early warning information sent by the earthquake monitoring devices with the number of all the earthquake monitoring devices and the preset proportion, the server sends second early warning information to the alarm module and/or the anti-seismic device.
The server simultaneously receives first early warning information sent by the earthquake monitoring devices with the number of all the earthquake monitoring devices and the preset proportion, and then sends second early warning information to the warning module and/or the anti-vibration device, wherein the first early warning information can be sent by the earthquake monitoring devices with the number of all the earthquake monitoring devices and the number of the earthquake monitoring devices being more than sixty percent, and then the second early warning information can be sent to the warning module and/or the anti-vibration device, and the preset proportion can be adjusted at any time according to actual conditions. For example, eight earthquake monitoring places are arranged in a target building, each earthquake monitoring place is provided with an earthquake monitoring device, each earthquake monitoring device comprises a vibration sensor, namely eight vibration sensors are arranged in the target building, and when a server receives first early warning information sent by more than five earthquake monitoring devices at the same time, the server sends second early warning information to an alarm module and/or a shockproof device.
Wherein, all the earthquake monitoring devices refer to all the earthquake monitoring devices recorded in the server,
it can be understood that an individual earthquake monitoring device may be manually removed, damaged or closed due to an unexpected factor, and at this time, the individual earthquake monitoring device is recorded in the server, and the server cannot receive the first warning information sent by the individual earthquake monitoring device, that is, the server cannot receive the first warning information sent by all earthquake monitoring devices at the same time. Therefore, when a larger number of earthquake monitoring devices are arranged, the server can send second early warning information to the alarm module and/or the anti-seismic device if the server simultaneously receives first early warning information sent by the earthquake monitoring devices with the number of all the earthquake monitoring devices and the preset proportion or more.
In addition, if the server receives first early warning information sent by more than a preset number of earthquake monitoring devices at the same time, second early warning information is sent to the warning module and/or the anti-seismic device, and if the server receives the first early warning information sent by all the earthquake monitoring devices at the same time, a monitoring device for monitoring whether the earthquake monitoring devices are in a normal working state is installed at the earthquake monitoring position.
For example, the earthquake monitoring device can be connected with the indicator light, and whether the earthquake monitoring device is in a working state or not is judged by determining the conditions of the indicator light and the like, so that the phenomenon that early warning cannot be generated due to the fact that the earthquake monitoring device is damaged is avoided, and the reliability of early warning of the earthquake monitoring device is improved.
The server receives the first early warning information sent by all the earthquake monitoring devices at the same time, and then sends second early warning information to the warning module and/or the anti-seismic device, so that the probability of the false alarm of the impending earthquake early warning information can be further reduced. The server simultaneously receives first early warning information sent by the earthquake monitoring devices with the number of all the earthquake monitoring devices and the preset proportion, and then sends second early warning information to the alarm module and/or the anti-seismic device, so that the probability of missing report of the impending earthquake early warning information can be further reduced. Specifically, a corresponding imminent earthquake prediction strategy can be adopted according to the actual geological condition and the protection requirement of the target building.
In an embodiment, the vibration sensor is a longitudinal vibration sensor.
Typically, the energy of seismic waves generated by an earthquake is large enough to cause vibration of the entire building structure. Namely, the amplitude of the vibration signal generated by the earthquake is not less than the preset amplitude threshold value of the vibration sensor in the target building structure or the vibration sensor at the periphery of the target building structure, and the vibration signal generated by the earthquake is stored by the data acquisition card and is uploaded to the server.
When an earthquake occurs, a vibration signal generated by the earthquake generally spreads outwards in a transverse wave and longitudinal wave mode, the longitudinal wave speed is high, the destructiveness is low, the transverse wave speed is low, and the destructiveness is high, so that the imminent earthquake can be determined by monitoring the vibration signal in the longitudinal wave mode generated by the earthquake through a longitudinal vibration sensor, and the imminent earthquake prediction information is sent before the earthquake or the imminent earthquake generated transverse wave is sent before the earthquake and/or a shockproof device is started to protect a target object in a target building.
The imminent earthquake forecasting method for the building provided by the embodiment of the invention is independent of an earthquake monitoring system of the national earthquake bureau or an earthquake early warning system of the national earthquake table net, is independent of the earthquake monitoring system of the national earthquake bureau (or the earthquake early warning system of the national earthquake table net), and is also a powerful supplement of the earthquake monitoring system of the national earthquake bureau (or the earthquake early warning system of the national earthquake table net).
