Detailed ways

The 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, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

1 to 3 , a method for predicting an impending earthquake for a building provided by an embodiment of the present invention includes:

S01. Determine the personnel flow route in the target building.

The flow route of people in the target building can be determined through the surveillance video in the target building.

S02, based on the personnel flow route, select a location in the target building where there is no personnel flow as an earthquake monitoring location.

Because people walking or working near the earthquake monitoring site will cause the vibration signal generated on the ground to reach the earthquake monitoring site, it will interfere with the accuracy of the impending earthquake prediction information obtained by monitoring the vibration signals from the ground at the earthquake monitoring site. The location where there is no movement of people in the target building is selected as the earthquake monitoring location.

In another embodiment, an imminent earthquake prediction method for a building provided by an embodiment of the present invention includes: determining a flow route of people or vehicles around a target building, and selecting a target based on the flow route of people or vehicles around the target building Locations around the building where there is no movement of people or vehicles are selected as earthquake monitoring locations. For example, when the target building is located in a suburb or an isolated area, the turnover rate of people around the target building is lower than that in the target building. At this time, setting up an earthquake monitoring station around the target building can reduce the probability of false alarms of impending earthquake prediction information. .

S03. Install an earthquake monitoring device at the earthquake monitoring site, the seismic monitoring device is used to monitor the vibration signal at the earthquake monitoring site, and when the amplitude of the vibration signal is not less than a preset amplitude threshold, send first warning information to the server.

The preset amplitude threshold means that it can be specifically set according to the earthquake resistance level of the target building, that is, when the earthquake monitoring device is applied to different buildings, the preset amplitude threshold value is independently set.

The first warning information is used to determine whether an earthquake is imminent.

The seismic monitoring device can monitor the vibration signal at the seismic monitoring site, and collect, store and process the monitored vibration signal, for example, obtain the amplitude of the monitored vibration signal, and compare the obtained amplitude of the monitored vibration signal with the preset value. Amplitude threshold for comparison.

A control module can be set in the earthquake monitoring device, and the control module uses a regular expression to process the result of comparing the amplitude of the vibration signal with the preset amplitude threshold and send the first warning information, so that the amplitude of the vibration signal is not less than the preset amplitude threshold. , the earthquake monitoring device sends the first warning information to the server.

S04, if the server simultaneously receives the first warning information sent by the earthquake monitoring device exceeding the preset number, then sends the second warning information to the alarm module and/or the anti-vibration device; the server is connected in communication with the alarm module and/or the anti-vibration device, and the first 2. Early warning information is used to warn whether an earthquake occurs at the location of the building.

Same as above, regular expressions can be used to process the quantity of the received first warning information and send the second warning information to the alarm module and/or the anti-vibration device, so that after the server receives the first warning information exceeding the preset number at the same time, The alarm module and/or the anti-vibration device sends out second warning information.

A network communication module can be installed on the alarm module and the anti-vibration device, or the alarm module and the anti-vibration device can be respectively connected to the server through optical fibers or network cables, so as to connect the server to the alarm module and/or the anti-vibration device in communication. After receiving the second warning information, the alarm module may send out an alarm signal, for example, the alarm module emits a buzzer sound and/or a flashing light with a preset frequency. The anti-vibration device can be activated directly after receiving the second warning information, for example, a preset airbag is inflated at a preset rate to wrap the target object in the target building.

The imminent earthquake forecasting method for buildings provided by the embodiments of the present invention determines the personnel flow route in the target building, and selects the location where no personnel flow in the target building as the earthquake monitoring location, so as to prevent vibrations generated by people walking or working. The signal is transmitted to the earthquake monitoring office to cause the false alarm of the imminent earthquake prediction information, and only when the first warning information exceeding the preset number is received, it is determined that an earthquake is imminent, and the imminent earthquake prediction information is further prevented from being falsely reported. By installing an earthquake monitoring device at the earthquake monitoring place, monitoring and processing the vibration signal at the earthquake monitoring place to obtain the amplitude of the vibration signal at the earthquake monitoring place, and determining whether there is a vibration signal based on the amplitude of the vibration signal at the earthquake monitoring place and the preset amplitude threshold An earthquake is imminent. Compared with determining whether an earthquake is imminent through the imminent earthquake early warning information issued by the State Earthquake Administration, the imminent earthquake prediction method for buildings provided by the embodiment of the present invention can provide a longer protection preparation time, and is more targeted for more effective protection for the building structure.

In order to reduce the probability of false alarms of the impending earthquake prediction information, in one embodiment, based on the personnel flow route, selecting a location without personnel flow as the earthquake monitoring location, including: based on the personnel flow route, selecting at least two locations without personnel flow and having The location of the stable building structure is used as an earthquake monitoring location; wherein, the distance between at least two locations with no personnel flow and having a stable building structure is not less than a preset distance.

It can be understood that it is sufficient to set up one earthquake monitoring station, but the more earthquake monitoring stations are set up, the higher the accuracy of the early warning information issued. The above preset distance means that the vibration signals generated when people walk, jump or work in the personnel flow route will not affect the two earthquake monitoring locations and the vibration signals generated when vehicles pass near the target building at the same time. The distance from the earthquake monitoring site. Selecting a location with a stable building structure as the earthquake monitoring location may be an earthquake monitoring location selected on a concrete structure that meets the conditions, wherein the stable building structure helps transmit vibration signals from the ground to the earthquake monitoring device.

Although the selected seismic monitoring site is a location without personnel flow, the seismic monitoring site may still receive interfering vibration signals. For example, vibration signals generated by vehicles passing near the target building or large vibration signals generated by unexpected events near the target building may be transmitted to the earthquake monitoring office, resulting in false alarms of impending earthquake prediction information. In the present application, by setting at least two earthquake monitoring locations separated by a preset distance, the probability of false alarms of impending earthquake prediction information can be reduced to a certain extent.

For example, referring to Fig. 2, on a multi-storey museum building structure, the first earthquake monitoring station 201 can be selected on the second floor of the museum building structure, and the second earthquake monitoring station 202 and the third earthquake monitoring station can be selected on the roof of the museum building structure. 203, and make the distances between the three seismic monitoring locations not less than the preset distance respectively. If the first earthquake monitoring office 201 of the museum building detects the vibration signal generated by people jumping, the first warning information is sent to the server, but because the first earthquake monitoring office 201 on the second floor of the museum building is connected to the roof of the museum building The distance between the second earthquake monitoring location 202 and the third earthquake monitoring location 203 is beyond the distance affected by the vibration signals generated by people jumping at the same time, so the vibration signals generated by people jumping cannot be monitored by the first earthquake monitoring of the building structure of the museum at the same time. The first earthquake monitoring office 201, the second earthquake monitoring office 202 and the third earthquake monitoring office 203 in the museum building structure will not send data to the server at the same time. First warning information, so the server can determine that the first warning information sent by the first earthquake monitoring office 201 on the second floor of the building structure of the museum is interference warning information.

The number and location of the earthquake monitoring locations and the installation location of the earthquake monitoring device in the method for predicting impending earthquakes for buildings provided by the embodiments of the present invention are relatively flexible. Includes: basements, rooftops, plumbing wells, and top corners in buildings. That is, when selecting an earthquake monitoring site, it is necessary to avoid human interference as much as possible.

It can be understood that the above-mentioned basements, rooftops, pipeline wells, and top corners in buildings are only examples of locations with no personnel flow and stable building structures, and are not intended to be used as examples of locations with no personnel flow and stable building structures. Scope limit.

In one embodiment, installing an earthquake monitoring device at the earthquake monitoring place includes: installing a vibration sensor of the earthquake monitoring device at the earthquake monitoring place, so that the vibration sensor monitors the vibration signal at the earthquake monitoring place; connecting the data acquisition card of the earthquake monitoring device with the The vibration sensor is connected, so that the data acquisition card receives the vibration signal sent by the vibration sensor, processes the vibration signal to obtain the amplitude of the vibration signal, and compares the amplitude of the vibration signal with the preset amplitude threshold; collects data from the server and the earthquake monitoring device The card is connected to a remote network, and if the amplitude of the vibration signal is not less than the preset amplitude threshold, the data acquisition card sends first warning information to the server.

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 , and 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, the first data acquisition card 1011, the first The second data acquisition card 1021 and the third data acquisition card 1031 are respectively connected to the remote network of the server.

As mentioned above, the seismic monitoring place can be selected on a concrete structure that meets the conditions. At this time, the seismic monitoring device can be installed at the seismic monitoring place using expansion bolts to monitor the vibration signal of the seismic monitoring place. Preferably, the seismic monitoring device is installed in the seismic monitoring place. Monitoring station to monitor longitudinal vibration signals at the seismic monitoring station. The data acquisition card and the vibration sensor are integrally connected or connected by a cable. When the data acquisition card and the vibration sensor are connected by a cable, one end of the cable can be connected to the vibration sensor, and the other end of the cable can be connected to the data acquisition card through the wiring board. And a lightning protection module is set 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 less than the preset amplitude threshold, the earthquake monitoring device starts to store and process the vibration signal it monitors, and sends the processed vibration signal to the server. Specifically, the vibration sensor is used to detect the vibration signal and send the detected vibration signal to the data acquisition card, and the data acquisition card is used to process the vibration signal and determine the amplitude of the vibration signal. When it is determined that the amplitude of the vibration signal sent by the vibration sensor is not less than The amplitude threshold is preset, and the first warning information is sent to the server, and the first warning information may include the switch signal 0 or 1. Because the data volume of the switch signal is extremely small and the network delay is low, it can be ensured that the first warning information can be sent to the server in time.

In order to facilitate the analysis of the vibration signal by the server, a memory card is provided in the earthquake monitoring device, and the memory card is used to store the vibration signal whose amplitude is not less than a preset amplitude threshold collected by the vibration sensor; After sending the first warning information to the server, the method further includes: sending a vibration signal in the memory card to the server. Sending the vibration signal in the memory card to the server may be sending the vibration signal in the memory card immediately after sending the first warning information, or may be sending the vibration signal in the memory card after a preset interval. Vibration signal.

In one embodiment, the remote network connection between the server and the data acquisition card of the earthquake monitoring device includes: a mobile communication module is provided on the data acquisition card, and the server is remotely connected to the server through the mobile communication module. network connection, or connect the data acquisition card to a gateway device, and connect to the server through a remote network through the gateway device.

The above-mentioned mobile communication module may be a 3G module, a 4G module or a 5G module. The gateway device may be a network router, wherein, to connect the data acquisition card to the gateway device, the data acquisition card may be connected to the network router through a cable. The server may be a cloud server.

A cloud server (also called a computing unit) is a simple, efficient, safe and reliable computing service with elastically scalable processing capabilities, and is characterized by easy management. The cloud server can be used to judge whether an earthquake is imminent after receiving the signal from the data acquisition card, and send out the impending earthquake forecast information by SMS, broadcast or other forms, or directly send the second early warning information to the anti-quake device. So that the anti-vibration device can be activated directly, for example, a preset airbag is inflated at a preset rate to wrap the target object in the target building.

The signal transmission between the earthquake monitoring device and the server through the network signal helps the server to quickly determine whether an earthquake is imminent, and can provide a longer protection preparation time to help effectively protect the building structure. It can be understood that the data acquisition card and the server can also be connected to a remote network through an electrical connection such as an optical fiber.

The earthquake monitoring device can be connected to an external power source, and the external power source can be industrial, civil or solar power, or a battery can be installed on the earthquake monitoring device, and the battery can be used to supply power to the earthquake monitoring device.

However, it is preferable to connect the seismic monitoring device to an external power source, because compared to supplying power to the seismic monitoring device through a battery, powering the seismic monitoring device through an external power source can ensure that the seismic monitoring device will not be unable to monitor the seismic monitoring site due to lack of power supply. The vibration signal can avoid the omission of the earthquake early warning information, and then ensure the reliability of the earthquake monitoring device.

In one embodiment, the remote network connection between the server and the data acquisition card of the seismic monitoring device includes: when the seismic monitoring site is a closed environment, installing a signal within a preset range of the seismic monitoring site an amplifier, where the signal amplifier is used to connect the data acquisition card with the server in a remote network.

The preset range of the seismic monitoring site refers to the installation range of the signal amplifier determined by the on-site installer according to the coverage of the signal amplifier and the structural conditions of the seismic monitoring site and its vicinity. The signal amplifier is used to connect the data acquisition card to the remote network of the server. Specifically, the mobile communication module on the data acquisition card can be connected to the remote network of the server under the action of the signal amplifier, or it can be connected to the data acquisition card. The gateway device is connected to the remote network of the server under the action of the signal amplifier.

It can be understood that the earthquake monitoring station may be set in a closed environment to avoid the interference of vibration signals generated by people walking around, jumping or other factors to the earthquake monitoring station, for example, setting the earthquake monitoring station in the basement Or pipeline well; the data acquisition card is mainly used to store and process the vibration signal whose amplitude is not less than the preset amplitude threshold sent by the vibration sensor, and send the first warning information to the server. Therefore, in order to ensure the reliability of the earthquake monitoring device, it is necessary to ensure that the network signal of the data acquisition card is good, and the signal test between the data acquisition card and the server is normal. When the earthquake monitoring station is set in a closed environment and the data acquisition card and the server are connected by a wireless network, the connection may be unstable. At this time, by installing a network signal amplifier, the connection between the data acquisition card and the server can be guaranteed. The stability of the remote network connection is improved, so as to avoid the omission of the early warning information of the imminent earthquake, thereby ensuring the reliability of the earthquake monitoring device.

In one embodiment, the server is connected to the alarm module and/or the anti-vibration device, and if the server simultaneously receives the first warning information sent by more than a preset number of earthquake monitoring devices, the first warning information is sent to the alarm module and/or the anti-vibration device. 2. Early warning information, including: if the server simultaneously receives the first early warning information sent by all the earthquake monitoring devices, sending the second early warning information to the alarm module and/or the anti-vibration device; or, if the server simultaneously receives the number of all the seismic monitoring devices The first warning information sent by the earthquake monitoring device whose specific gravity is higher than the preset specific gravity, the second warning information is sent to the alarm module and/or the anti-vibration device.

The server simultaneously receives the first warning information sent by the earthquake monitoring devices with a preset proportion of the number of all the earthquake monitoring devices, and then sends the second warning information to the alarm module and/or the anti-vibration device, which may be that the server simultaneously receives all the earthquake monitoring devices If more than 60% of the earthquake monitoring devices send the first warning information, the second warning information will be sent to the alarm module and/or the anti-vibration device, wherein the preset proportion can be adjusted at any time according to the actual situation. For example, there are eight earthquake monitoring locations in the target building, each earthquake monitoring location is provided with an earthquake monitoring device, and each earthquake monitoring device includes a vibration sensor, that is, eight vibration sensors are arranged in the target building, and the server simultaneously When the first warning information sent by more than five earthquake monitoring devices is received, the second warning information is sent to the alarm module and/or the anti-vibration device.

Among them, all earthquake monitoring devices refer to all earthquake monitoring devices filed in the server,

It is understandable that an individual earthquake monitoring device may be dismantled, damaged or turned off due to unexpected factors. At this time, the individual earthquake monitoring device has a record 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 the earthquake monitoring devices at the same time. Therefore, when setting a larger number of earthquake monitoring devices, it can be configured that if the server simultaneously receives the first warning information sent by the earthquake monitoring devices with a preset proportion of the number of all the earthquake monitoring devices, the server will send the alarm module and/or the first warning information to the alarm module and/or Or the anti-vibration device sends out a second warning message.

In addition, if the server simultaneously receives the first warning information sent by more than a preset number of earthquake monitoring devices, it sends out the second warning information to the alarm module and/or the anti-vibration device. If the first warning information is used, when the second warning information is sent to the alarm module and/or the anti-vibration device, a monitoring device for monitoring whether the seismic monitoring device is in a normal working state is installed at the earthquake monitoring place.

For example, the earthquake monitoring device can be connected to the indicator light, and the status of the indicator light can be determined to determine whether the earthquake monitoring device is in working state, so as to avoid the failure to generate an early warning due to the damage of the earthquake monitoring device, thereby increasing the reliability of the early warning of the earthquake monitoring device. sex.

The server receives the first warning information sent by all the earthquake monitoring devices at the same time, and then sends the second warning information to the alarm module and/or the anti-vibration device, which can further reduce the probability of false alarms of the imminent earthquake warning information. The server simultaneously receives the first warning information sent by the earthquake monitoring devices with a preset proportion of all the earthquake monitoring devices, and then sends the second warning information to the alarm module and/or the anti-vibration device, which can further reduce the missed report of the imminent earthquake warning information. The probability. Specifically, corresponding imminent earthquake prediction strategies can be adopted according to the actual geological conditions and the protection requirements of the target buildings.

In one embodiment, the vibration sensor is a longitudinal vibration sensor.

The energy of seismic waves produced by ordinary earthquakes is large enough to vibrate the entire building structure. That is, the amplitude of the vibration signal generated by the earthquake is not less than the preset amplitude threshold of the vibration sensor in the target building structure or the vibration sensor around the target building structure. The vibration signal generated by the earthquake will be stored by the data acquisition card and uploaded to the server.

When an earthquake occurs, the vibration signals generated by the earthquake generally propagate outward in the form of transverse waves and longitudinal waves. The longitudinal waves are fast and destructive, while the transverse waves are slow and destructive. It can be determined that an earthquake is imminent, and before the earthquake or the shear wave generated by the earthquake, the imminent earthquake prediction information is sent and/or the anti-vibration device is activated to protect the target object in the target building.
