Referring to fig. 5, a geological disaster monitoring method based on seismic signals is further provided in the preferred embodiment of the present invention, and the method is applied to the geological disaster monitoring system 10 based on seismic signals. It should be noted that the method provided by the embodiment of the present invention is not limited by the specific sequence described in fig. 5 and below. The method comprises the following specific steps:
step S110, the base station 300 monitors the seismic signal in the area to be monitored, and obtains the corresponding seismic signal intensity when the presence of the seismic signal is monitored.
In this embodiment, the seismic signal may be, but is not limited to, an acceleration signal, and the base station 300 may be provided with an acceleration sensor 332 for monitoring the acceleration signal, and when the acceleration signal is monitored, the acceleration signal is subjected to signal processing to obtain corresponding acceleration information, where the acceleration information is used to represent the intensity of the seismic signal.
Step S120, a first control instruction is sent to the field acquisition terminal 100 according to the seismic signal intensity.
In this embodiment, the first control instruction may include configuration information of the acquisition frequency of the field acquisition terminal 100, and specifically, referring to fig. 6, the step S120 may include the following sub-steps:
substep S121, calculating an intensity difference between the seismic signal intensity and each preset intensity threshold.
Specifically, the preset intensity threshold may be preset, and as an embodiment, the preset intensity threshold may be set to 0.05g, 0.1g, 0.2g, 0.3g, 0.4g, 0.5g, and on the basis of the preset intensity threshold, intensity differences between the seismic signal intensity and 0.05g, 0.1g, 0.2g, 0.3g, 0.4g, 0.5g are calculated, respectively.
And a substep S121, selecting a preset intensity threshold corresponding to the minimum intensity difference value among the intensity difference values as a target intensity threshold.
And a substep S121, obtaining a control strategy corresponding to the target intensity threshold, and sending a corresponding first control instruction to the field acquisition terminal 100 according to the control strategy.
In this embodiment, the preset intensity threshold corresponding to the minimum intensity difference value is selected from the calculated intensity difference values, and is the preset intensity threshold closest to the seismic signal, and as an optimal selection, the preset intensity threshold is used as a target intensity threshold, and then a control strategy corresponding to the target intensity threshold is obtained, and the control strategy is sent to the field acquisition terminal 100.
As an example, the control strategies corresponding to 0.05g, 0.1g, 0.2g, 0.3g, 0.4g, and 0.5g of the preset intensity thresholds are acquisition strategies with acquisition periods of 5Hz, 10Hz, 20Hz, 30Hz, 40Hz, and 50Hz, respectively, if the seismic signal acquired by the base station 300 is 0.22g, the intensity differences between the seismic signal intensity and the preset intensity thresholds are 0.17g, 0.12g, 0.02g, 0.08g, 0.18g, and 0.28g, respectively, wherein the minimum intensity difference is 0.02g, and the corresponding preset intensity threshold is 0.2g, so the acquired control strategy is the acquisition strategy with an acquisition period of 20 Hz.
Referring to fig. 5 again, in step S130, the field collection terminal 100 collects disaster data of the area to be monitored according to the first control instruction, and sends the collected disaster data to the base station 300.
In detail, taking the above control policy as an example of an acquisition policy with an acquisition cycle of 20Hz, after receiving the control policy with an acquisition frequency of 20Hz sent by the base station 300, the on-site acquisition terminal 100 acquires disaster data of the area to be monitored at the acquisition frequency of 20Hz, and then sends the acquired data to the base station 300, so as to send the data to the server 500 through the base station 300.
In this embodiment, the disaster data may include at least one of displacement data, inclination data, settlement data, convergence data, deformation data, tension data, pressure data, pre-stress data, osmotic pressure data, temperature data, soil moisture content data, and infrasound data.
Step S140, the base station 300 switches the current communication mode to the beidou satellite communication mode when the mobile communication mode is interrupted, and sends the disaster data to the server 500 through the beidou satellite communication mode.
In detail, when the mobile communication mode is interrupted due to a large seismic signal strength, the base station 300 may switch the current communication mode to the beidou satellite communication mode, and send the disaster data to the server 500 through the beidou satellite communication mode.
Optionally, in other embodiments, the disaster data may be transmitted in a mobile communication manner and a beidou satellite communication manner at the same time, or in a beidou satellite communication manner alone, or in any other communication manner that can be used for data transmission.
Step S150, the server 500 generates a corresponding geological disaster data report according to the disaster data.
In detail, in this embodiment, the server 500 stores a geological disaster analysis model and a relationship between a geological disaster occurrence probability and a geological disaster occurrence level. The server 500 analyzes the disaster data by using the geological disaster analysis model to obtain a corresponding geological disaster occurrence probability, and then obtains a corresponding geological disaster occurrence grade according to a relationship between the geological disaster occurrence probability and the geological disaster occurrence grade. For example, the probability of occurrence of the geological disaster may be determined to be 0-10%, 10-20%, 20-40% and 40-90%, and the corresponding geological disaster occurrence level may be a blue warning level, a yellow warning level, an orange warning level and a red warning level.
Further, referring to fig. 7, the geological disaster monitoring system 10 based on seismic signals may further include a user terminal communicatively connected to the server 500. The user terminal may be, but is not limited to, a smart phone, an intelligent wearable Device, a Personal Computer (PC), a notebook Computer, a tablet PC, a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), and the like. The method further comprises the following steps:
in step S260, the server 500 receives the control policy configuration information sent by the user terminal, and sends the control policy configuration information to the base station 300.
In this embodiment, the control policy configuration information includes an interval acquisition control policy, a timing acquisition control policy, and a variable frequency acquisition control policy based on seismic signals. The interval acquisition control strategy is a control strategy for acquiring at intervals of preset intervals, for example, acquiring an hour at intervals of five minutes, the timing acquisition control strategy is a control strategy for acquiring at every preset time point, for example, 0 point, 6 points, 12 points and 18 points every day, the variable frequency acquisition control strategy based on the seismic signals is a control strategy for configuring fixed acquisition frequency and different acquisition frequency according to different acceleration threshold values, for example, the fixed acquisition frequency can be uniformly set as a fixed acquisition frequency value according to 0.05g, 0.1g, 0.2g, 0.3g, 0.4g and 0.5g in a preset intensity threshold value, for example, the fixed acquisition frequency can be set as 50 Hz; the different collection frequencies can be collection strategies with collection periods of 5Hz, 10Hz, 20Hz, 30Hz, 40Hz and 50Hz according to control strategies respectively corresponding to 0.05g, 0.1g, 0.2g, 0.3g, 0.4g and 0.5g in the preset intensity threshold values.
Step S270, the base station 300 configures a pre-stored control policy according to the control policy configuration information, and controls the field acquisition terminal 100 according to the configured control policy.
