Description

Technical Field

[0001] The invention belongs to the technical field of geological exploration, and in particular relates to a geological exploration and survey safety early warning system. Background Art

[0002] Tunnel construction generally refers to the New Austrian Tunnel Construction Method, which fully utilizes the self-bearing capacity of the surrounding rock and the spatial constraints of the excavation surface. It uses anchor rods and shotcrete as the main support means to reinforce the surrounding rock and restrain its relaxation and deformation. It also ensures the smooth construction of underground projects through measurement and monitoring of the surrounding rock and support.

[0003] For example, the Chinese patent publication number CN113362469B discloses a shield tunnel construction early warning method that integrates urban building information and stratigraphic structure. The invention combines the city's surface model with a stratigraphic model based on exploration drilling data to form a refined surface geological model, accurately restores the actual surface geological conditions, and combines the refined surface geological model with the shield tunnel model to delineate the impact level of surface buildings and the dangerous stratigraphic areas where the shield tunnel passes through, forming a refined geological model. By real-time observation of the relative position relationship between the shield tunnel and the dangerous stratigraphic areas and high-rise buildings in different mileage sections of the geological model, construction warning instructions are issued in real time, and a multi-indicator graded early warning plan and a corresponding risk control measures database are established. The monitoring and measurement information of each mileage section is monitored in real time, and compared and analyzed with the specified range of each indicator in the database. Combined with the actual on-site engineering conditions and the refined geological model, the corresponding prevention and control measures are optimized and construction warnings are issued.

[0004] However, this solution still has certain flaws. During the monitoring process of each mileage section, staff are required to collect on-site geological exploration drilling data to establish a detailed geological model, which requires a large investment of manpower and material resources. At the same time, manual operations are greatly affected by the geographical environment and weather, and the accuracy of the measured data cannot be guaranteed. Summary of the Invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a geological exploration and survey safety early warning system that is convenient for real-time monitoring of tunnel geological changes and has high monitoring accuracy.

[0006] In order to achieve the above object, the technical solution of the present invention is as follows:

[0007] A geological prospecting and exploration safety early warning system includes a detection module, a data processing module and an early warning module;

[0008] A detection module, consisting of a plurality of seismic wave detection points, is used to detect seismic wave information and coordinate information of each seismic wave detection point in the geological area surrounding the tunnel, and send the seismic wave information and coordinate information of each seismic wave detection point to the data processing module;

[0009] A data processing module is used to record coordinate information and seismic wave information, remove interference waves in the seismic wave information based on the seismic wave information, obtain new seismic wave information, and thus draw a geological picture C. The characteristic value c of the geological picture C is extracted and compared with the threshold value A and the threshold value B. The threshold value A is less than the threshold value B.

[0010] If the characteristic value c is greater than or equal to threshold A and the characteristic value c is less than or equal to threshold B, the data processing module sends a first-level warning instruction to the detection module and the early warning module, reducing the frequency of tunnel construction or temporarily stopping tunnel construction. The detection module re-detects seismic wave information through the seismic wave detection point, and the data processing module re-processes the seismic wave information to eliminate the impact of tunnel construction on seismic wave information detection;

[0011] If the characteristic value c is less than the threshold value A, a safety message is sent to the early warning module; if the characteristic value c is greater than the threshold value B, a secondary warning instruction is sent to the early warning module;

[0012] Warning module: Based on safety information, the green safety indicator of the warning module flashes; based on the first-level warning instruction, the yellow safety indicator of the warning module flashes; based on the second-level warning instruction, the red safety indicator of the warning module flashes;

[0013] Data processing module, including data acquisition module, clutter removal module, clutter comparison module, work control module and storage module;

[0014] The data acquisition module performs A / D conversion on the coordinate information and seismic wave information detected by the detection module;

[0015] The clutter removal module removes random noise from the seismic wave information using the fx domain random noise attenuation method based on the seismic wave information to obtain new seismic wave information, thereby drawing a geological image C and extracting the size of the shadow area in the geological image C to obtain the eigenvalue c;

[0016] The clutter comparison module compares the characteristic value c with the set thresholds A and B;

[0017] If the characteristic value c is greater than or equal to threshold A and the characteristic value c is less than or equal to threshold B, the data processing module sends a first-level warning instruction to the detection module and the early warning module, reducing the frequency of tunnel construction or temporarily stopping tunnel construction. The detection module re-detects seismic wave information through the seismic wave detection point, and the data processing module re-processes the seismic wave information to reduce the impact of tunnel construction factors on seismic wave information detection;

[0018] If the characteristic value c is less than the threshold value A, a safety message is sent to the early warning module; if the characteristic value c is greater than the threshold value B, a secondary warning instruction is sent to the early warning module;

[0019] The work control module, based on the first-level warning instruction, issues a reminder to the person in charge of tunnel construction to reduce the frequency of tunnel construction or temporarily stop tunnel construction. It also controls the seismic wave detection points in the detection module to re-detect seismic wave information. The data processing module re-processes the seismic wave information to reduce the impact of tunnel construction factors on seismic wave information detection.

[0020] The storage module is used to store and record the coordinate information and seismic wave information corresponding to each seismic wave detection point.

[0021] The above solution achieves the following beneficial effects: First, multiple seismic wave detection points are set up in the area surrounding the tunnel. The seismic wave information and coordinate information detected by each seismic wave detection point are sent to the data processing module through the detection module, so that it can monitor the geological changes of the tunnel in real time, replace some manual real-time detection, improve work efficiency, provide a large amount of data, and speed up the detection progress;

[0022] The data processing module first removes random noise from the seismic wave information using the fx domain random noise attenuation method to obtain new seismic wave information, thereby drawing a geological picture C. The size of the shadow area in the geological picture C is extracted to obtain the eigenvalue c, which is then compared with the set thresholds A and B.

[0023] If the characteristic value c is greater than or equal to threshold A and the characteristic value c is less than or equal to threshold B, the data processing module sends a first-level warning instruction to the detection module and the early warning module. The yellow safety indicator light of the early warning module flashes, reminding the geological exploration personnel to temporarily stop work and reminding the construction personnel to reduce the frequency of tunnel construction or temporarily stop tunnel construction. The detection module re-detects the seismic wave information through the seismic wave detection point, and the data processing module re-processes the seismic wave information to eliminate the influence of tunnel construction on the seismic wave information detection, improve the measurement data accuracy, and ensure the monitoring accuracy;

[0024] If the eigenvalue c is less than the threshold A, a safety message is sent to the early warning module; if the eigenvalue c is greater than the threshold B, a secondary warning instruction is sent to the early warning module, and the red safety indicator light of the early warning module flashes to remind construction personnel that the geology near the tunnel has changed, ensuring the safety of geological exploration personnel.

[0025] Furthermore, the data processing module also includes a seismic wave detection point comparison module, which compares the coordinate information of the same seismic wave detection point received each time with the coordinate information of the same seismic wave detection point received last time, calculates the coordinate position change distance of the same seismic wave detection point, and compares the coordinate position change distance with a threshold value D;

[0026] If the coordinate position change distance is greater than or equal to the threshold D, a warning message d is sent to the warning module. The warning module controls the purple safety indicator light to flash based on the warning message d. If the coordinate position change distance is less than the threshold D, a safety message is sent to the warning module.

[0027] Beneficial effect: The seismic wave detection point comparison module can detect the position of the same seismic wave detection point, avoid changes in the position of the seismic wave detection point, ensure the detection effect of the seismic wave detection point, and thus improve the accuracy of monitoring.

[0028] Furthermore, the coordinate information includes GPS positioning information of the seismic wave detection point.

[0029] Beneficial effect: GPS positioning information facilitates confirmation of the location of seismic wave detection points.

[0030] Furthermore, tunnel construction factors include vibrations generated by construction and noise generated during construction.

[0031] Beneficial effects: The vibration and noise generated during construction are both random noise. The fx domain random noise attenuation method uses the predicted linear phase axis on the post-stack seismic profile to separate the signal and noise and enhance the effective signal. This method can remove the influence of tunnel construction factors on seismic wave information and improve monitoring accuracy.

[0032] Furthermore, the locations of the seismic wave detection points are arranged horizontally along the tunnel construction direction.

[0033] Beneficial effects: The horizontally arranged seismic wave detection points facilitate the detection of geological conditions around the tunnel, and can detect the impact of tunnel construction on the tunnel surroundings, thus avoiding the occurrence of foundation subsidence caused by tunnel construction.

[0034] Furthermore, the characteristic value c is obtained by image processing software.

[0035] Beneficial effect: Image processing software such as Adobe Photoshop software can quickly process geological image C.

[0036] Furthermore, the distance of the coordinate position change is calculated using a three-dimensional coordinate method.

[0037] Beneficial effect: The three-dimensional coordinates correspond to the GPS positioning information, which makes it easy to calculate the distance of the coordinate position change after the seismic wave detection point changes.

[0038] Furthermore, based on the first-level warning instruction, the working control module controls the seismic wave detection points near the coordinates of the abnormal location in the detection module to re-detect the seismic wave information.

[0039] Beneficial effects: It enables accurate detection of abnormal locations, makes the obtained geological picture C clearer and more accurate, and improves monitoring accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Figure 1 Schematic diagram of a geological prospecting and exploration safety early warning system according to an embodiment of the present invention. DETAILED DESCRIPTION

[0041] The following is further described in detail through specific implementation methods:

[0042] The embodiment is basically as shown in the attached Figure 1 Shown: A geological prospecting and investigation safety early warning system, including a detection module, a data processing module and an early warning module;

[0043] The detection module is composed of a number of seismic wave detection points, which are arranged horizontally along the tunnel construction direction. It is used to detect seismic wave information and coordinate information of each seismic wave detection point in the geological area around the tunnel. The coordinate information includes the GPS positioning information of the seismic wave detection point, and sends the seismic wave information and coordinate information of each seismic wave detection point to the data processing module;

[0044] a data processing module for recording coordinate information and seismic wave information, removing interference waves from the seismic wave information based on the seismic wave information, obtaining new seismic wave information, thereby drawing a geological picture C, extracting a characteristic value c of the geological picture C (the characteristic value c is obtained by processing with image processing software, such as Adobe Photoshop software), and comparing it with a threshold value A and a threshold value B, where threshold value A is less than threshold value B;

[0045] If the characteristic value c is greater than or equal to threshold A and the characteristic value c is less than or equal to threshold B, the data processing module sends a first-level warning instruction to the detection module and the early warning module, reducing the frequency of tunnel construction or temporarily stopping tunnel construction. The detection module re-detects seismic wave information through the seismic wave detection point, and the data processing module re-processes the seismic wave information to eliminate the impact of tunnel construction on seismic wave information detection;

[0046] If the characteristic value c is less than the threshold value A, a safety message is sent to the early warning module; if the characteristic value c is greater than the threshold value B, a secondary warning instruction is sent to the early warning module;

[0047] Warning module: Based on safety information, the green safety indicator of the warning module flashes; based on the first-level warning instruction, the yellow safety indicator of the warning module flashes; based on the second-level warning instruction, the red safety indicator of the warning module flashes;

[0048] Data processing module, including data acquisition module, clutter removal module, clutter comparison module, work control module and storage module;

[0049] The data acquisition module performs A / D conversion on the coordinate information and seismic wave information detected by the detection module;

[0050] The clutter removal module removes random noise from the seismic wave information using the fx domain random noise attenuation method based on the seismic wave information to obtain new seismic wave information, thereby drawing a geological image C and extracting the size of the shadow area in the geological image C to obtain the eigenvalue c;

[0051] The clutter comparison module compares the characteristic value c with the set thresholds A and B;

[0052] If the characteristic value c is greater than or equal to threshold A and the characteristic value c is less than or equal to threshold B, the data processing module sends a first-level warning instruction to the detection module and the early warning module, reducing the frequency of tunnel construction or temporarily stopping tunnel construction. The detection module re-detects seismic wave information through the seismic wave detection point, and the data processing module re-processes the seismic wave information to reduce the impact of tunnel construction factors on seismic wave information detection. Tunnel construction factors include vibration and noise generated during construction.

[0053] If the characteristic value c is less than the threshold value A, a safety message is sent to the early warning module; if the characteristic value c is greater than the threshold value B, a secondary warning instruction is sent to the early warning module;

[0054] The work control module, based on the first-level warning instruction, issues a reminder to the person in charge of tunnel construction to reduce the frequency of tunnel construction or temporarily stop tunnel construction. It also controls the seismic wave detection points near the coordinates of the abnormal location in the detection module to re-detect the seismic wave information. The data processing module re-processes the seismic wave information to reduce the impact of tunnel construction factors on seismic wave information detection.

[0055] The storage module is used to store and record the coordinate information and seismic wave information corresponding to each seismic wave detection point.

[0056] The specific implementation process is as follows:

[0057] like Figure 1 As shown, first, the staff arranged multiple seismic wave detection points horizontally along the tunnel construction direction, and sent the seismic wave information and coordinate information detected by each seismic wave detection point to the data processing module through the detection module, so that it can monitor the geological changes of the tunnel in real time, replace part of the manual real-time detection, improve work efficiency, provide a large amount of data, and speed up the detection progress.

[0058] The data processing module first removes random noise from the seismic wave information through the fx domain random noise attenuation method to obtain new seismic wave information, thereby drawing a geological picture C, extracting the size of the shadow area in the geological picture C, obtaining the eigenvalue c, and comparing the eigenvalue c with the set thresholds A and B.

[0059] If the eigenvalue c is greater than or equal to threshold A and the eigenvalue c is less than or equal to threshold B, the data processing module sends a first-level warning instruction to the detection module and the early warning module. The yellow safety indicator light of the early warning module flashes, reminding the geological exploration personnel to temporarily stop work and reminding the construction personnel to reduce the frequency of tunnel construction or temporarily stop tunnel construction. The detection module re-detects the seismic wave information through the seismic wave detection point, and the data processing module re-processes the seismic wave information to eliminate the impact of tunnel construction on seismic wave information detection, improve the measurement data accuracy, and ensure monitoring accuracy.

[0060] If the eigenvalue c is less than the threshold A, a safety message is sent to the early warning module; if the eigenvalue c is greater than the threshold B, a secondary warning instruction is sent to the early warning module, and the red safety indicator light of the early warning module flashes to remind construction personnel that the geology near the tunnel has changed, ensuring the safety of geological exploration personnel.

[0061] Example 2

[0062] The difference from the above embodiment is that the data processing module also includes a seismic wave detection point comparison module, which compares the coordinate information of the same seismic wave detection point received each time with the coordinate information of the same seismic wave detection point received last time, the coordinate information includes the GPS positioning information of the seismic wave detection point, and calculates the coordinate position change distance of the same seismic wave detection point. The coordinate position change distance is calculated using a three-dimensional coordinate method, and the coordinate position change distance is compared with a threshold value D;

[0063] If the coordinate position change distance is greater than or equal to the threshold D, a warning message d is sent to the warning module. The warning module controls the purple safety indicator light to flash based on the warning message d. If the coordinate position change distance is less than the threshold D, a safety message is sent to the warning module.

[0064] The specific implementation process is as follows: During the operation of the seismic wave detection point, the position of the same seismic wave detection point can be detected through the seismic wave detection point comparison module, and the coordinate position change distance of the same seismic wave detection point is obtained by calculation. The coordinate position change distance is compared with the threshold D. If the coordinate position change distance is greater than or equal to the threshold D, an early warning message d is sent to the early warning module, and the purple safety indicator light of the early warning module flashes, reminding the staff to rearrange the seismic wave detection point to ensure the detection effect of the seismic wave detection point, thereby improving the accuracy of monitoring.

[0065] The above is only an embodiment of the present invention, and common knowledge such as the specific structure and / or characteristics of the scheme is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
