Description

Technical Field

[0001] This invention relates to the field of underground pipeline protection marking technology, and in particular to an underground pipeline protection marking device for monitoring geological deformation. Background Technology

[0002] Warning posts in the existing technology are used to indicate the location of underground pipelines. Since underground pipelines are buried underground, the underground soil and rock will deform over time, which will lead to pipeline deformation and even affect the transmission of lines in the pipeline. Therefore, it is necessary to monitor the geological deformation data around the pipeline.

[0003] Chinese Patent Publication No. CN113345314A discloses an Internet of Things (IoT) based warning post and its method, including a marker post, a fixed support device, and a monitoring device. The marker post has a hollow internal structure, and its surface has two symmetrical mounting surfaces. The fixed support devices are symmetrically distributed in pairs on the mounting surfaces. The monitoring device is installed inside the marker post and uses various sensors to monitor changes in underground pipelines and their surroundings in real time. This data is then transmitted back to a monitoring and intelligent center, allowing maintenance personnel to determine the pipeline's location and understand its real-time status. This improves emergency response capabilities, promptly eliminates safety hazards in underground pipelines and surrounding facilities, extends the lifecycle of underground pipeline facilities, and provides comprehensive information-assisted decision-making. Therefore, it can be seen that the aforementioned IoT-based warning post and method have limitations. Due to the different estimated geological states of the underground rock and soil, the degree and probability of geological deformation of the underground rock and soil in different estimated geological states will also be different, and the underground pipelines in the underground rock and soil in different estimated geological states will also be affected differently. By using a control module to determine the estimated geological state based on geological structure parameters, and judging whether the estimated geological state is compacted or loose, the estimated geological state of the underground rock and soil is divided into two states, which solves the problem of low accuracy of the marking device in monitoring geological deformation around the pipeline. Summary of the Invention

[0004] To address this, the present invention provides an underground pipeline protection marking device for monitoring geological deformation. This overcomes the limitations of existing technologies where the estimated geological state of the underground rock and soil varies, leading to different degrees and probabilities of geological deformation and varying impacts on underground pipelines within the same geological state. The invention uses a control module to determine the estimated geological state based on geological structure parameters, classifying it as either compacted or loose. This approach categorizes the estimated geological state of the underground rock and soil into two states, thus resolving the issue of low accuracy in monitoring geological deformation around pipelines.

[0005] To achieve the above objectives, the present invention provides an underground pipeline protection marking device for monitoring geological deformation, comprising:

[0006] The underground pipeline protection marker post is set above the underground pipeline and includes a base buried underground and a warning section located above the base. The warning section is equipped with a pipeline type identification area and a depth information nameplate. The base is equipped with a triaxial accelerometer for monitoring the tilt angle of the underground rock and soil.

[0007] A noise monitoring module, which is connected to the underground pipeline protection marker post, is used to monitor the amplitude of noise.

[0008] A filtering module, connected to the noise monitoring module, is used to determine the filtering mode based on the amplitude of the noise, and to determine the noise location based on the noise characteristic parameters;

[0009] A control module, connected to the noise monitoring module, the underground pipeline protection marker post, and the filtering module, is used to determine the estimated geological condition based on geological structure parameters, and to determine whether to activate the filtering module based on the estimated geological condition and the noise location.

[0010] Furthermore, the power consumption ratio of the filtering module determines whether to use the filtering results of adjacent marking devices for fitting.

[0011] The estimated geological conditions include compacted and loose states.

[0012] Furthermore, the geological structure parameter = 1 / (average hardness of underground rock and soil × average density of underground rock and soil).

[0013] Furthermore, the control module is also used to determine the estimated geological state as the compacted state based on the geological structure parameters being less than the preset geological structure parameters, and to determine the estimated geological state as the loose state based on the geological structure parameters being greater than or equal to the preset geological structure parameters.

[0014] Furthermore, the control module is connected to the triaxial accelerometer to determine the number of samples to be collected for the inclination angle of the underground rock and soil mass based on the estimated geological state to which the current underground rock and soil mass belongs, wherein the number of samples collected in the compacted state is less than the number of samples collected in the loose state.

[0015] Furthermore, the control module is connected to the triaxial accelerometer and is also used to determine the detection cycle of the triaxial accelerometer according to the estimated geological state of the current underground rock and soil mass, wherein the detection cycle of the compacted state is longer than the detection cycle of the loose state.

[0016] Furthermore, the filtering module is connected to the noise monitoring module to obtain the frequency and propagation speed of the noise, and to determine the noise location as internal noise based on the fact that the frequency is less than a preset frequency and the propagation speed is greater than a preset propagation speed;

[0017] The noise location is determined to be external noise based on the fact that the frequency is greater than or equal to a preset frequency and the propagation speed is less than or equal to a preset propagation speed.

[0018] Internal noise refers to noise transmitted from within the underground rock and soil body, while external noise refers to noise transmitted from above the underground rock and soil body.

[0019] Furthermore, the control module is connected to the filtering module to determine the activation of the filtering module based on the estimated geological state being compact and the noise location being internal noise.

[0020] Based on the fact that the noise location is external noise, the filtering module is activated.

[0021] Based on the estimated geological condition being soft and the noise location being internal noise, it is determined that the filtering module will not be activated.

[0022] Furthermore, the filtering module is connected to the noise monitoring module and is also used to determine the first filtering mode to be adopted based on the noise amplitude being less than a preset amplitude threshold, and to determine the second filtering mode to be adopted based on the noise amplitude being greater than or equal to the preset amplitude threshold.

[0023] The gain adjustment range of the first filtering mode is smaller than that of the second filtering mode.

[0024] Furthermore, the control module is connected to the filtering module and is also used to fit the filtering results of adjacent identification devices if the power consumption ratio of the filtering module is less than a preset ratio.

[0025] Furthermore, the warning section is equipped with a light strip for displaying the state of geological deformation, wherein the light strip includes several indicator lights of different colors.

[0026] Compared with the prior art, the beneficial effect of the present invention is that, since the estimated geological state of the underground rock and soil body is different, the degree and probability of geological deformation of the underground rock and soil body under different estimated geological states will also be different, and the underground pipelines in the underground rock and soil body under different estimated geological states will also be affected differently. By determining the estimated geological state based on the geological structure parameters through the control module, the estimated geological state is determined to be either compact or loose, and the estimated geological state of the underground rock and soil body is divided into two states. This solves the problem that the traditional monitoring strategy relies on a fixed monitoring method and cannot adapt to different estimated geological states, and improves the adaptability of the underground pipeline protection and marking device to different geological conditions.

[0027] Furthermore, since the degree and probability of geological deformation of the underground rock and soil bodies under different estimated geological states are different, the degree and probability of geological deformation of the underground rock and soil bodies under the estimated geological state of compaction are smaller than those under the estimated geological state of looseness. By determining the number of samples of the inclination angle of the underground rock and soil body and the detection cycle of the triaxial accelerometer according to the estimated geological state to which the current underground rock and soil body belongs, the control module realizes the rational allocation of resources and reduces the energy consumption of the marking device.

[0028] Furthermore, since the internal and external noise under different estimated geological conditions have different effects on the detection results of the triaxial accelerometer, when the estimated geological condition is soft and the noise location is internal, the propagation of internal noise through the underground rock and soil in the soft geological condition is weakened, thus having little impact on the detection results of the triaxial accelerometer. Therefore, the control module determines not to activate the filtering module based on the estimated geological condition being soft and the noise location being internal. Conversely, when the estimated geological condition is compacted and the noise location is internal, the propagation of internal noise through the compacted geological condition is weakened, thus having little impact on the detection results of the triaxial accelerometer. If the internal noise propagates normally in the compacted underground soil and rock, it has a significant impact on the detection results of the triaxial accelerometer. Therefore, the control module determines to activate the filtering module to filter out the noise based on the estimated geological state being compacted and the noise location being internal noise. If the noise location is external noise, the external noise has a significant impact on the detection results of the triaxial accelerometer. Therefore, the control module determines to activate the filtering module to filter out the noise based on the noise location being external noise. This achieves the activation and deactivation of the filtering module according to the above different conditions, reducing the energy consumption of the filtering module.

[0029] Furthermore, the control module determines the filtering mode based on the amplitude of the noise, which solves the problem of insufficient filtering capability and high energy consumption caused by the fixed filtering mode of traditional filtering modules. By adopting different filtering modes for different noise amplitudes, the filtering capability of the filtering module is improved and the energy consumption of the filtering module is reduced.

[0030] Furthermore, if the power consumption ratio of the filtering module is less than the preset ratio, the control module will use the filtering results of the adjacent signage devices for fitting, that is, use the filtering results of the adjacent signage devices as the filtering results of this signage device. This solves the problem that the filtering module cannot operate and cannot filter noise because the power consumption ratio of the filtering module is less than the preset ratio, and enables the filtering module to obtain filtering results even when there is insufficient energy.

[0041] This invention provides an underground pipeline protection marking device for monitoring geological deformation, comprising:

[0042] The underground pipeline protection marker post 1 is set above the underground pipeline and includes a base part 101 buried underground and a warning part 102 located above the base part 101. The warning part 102 is provided with a pipeline type identification area and a depth information nameplate. The base part 101 is equipped with a triaxial accelerometer 2 for monitoring the tilt angle of the underground rock and soil 3.

[0043] A noise monitoring module, which is connected to the underground pipeline protection marker post 1, is used to monitor the amplitude of noise and includes a sound wave receiver and a signal amplifier.

[0044] Specifically, the noise includes: noise generated by the release of internal stress in the soil and rock layers caused by geological deformation, and noise generated by vibration of surface construction machinery or traffic loads.

[0045] A filtering module, connected to the noise monitoring module, is used to determine the filtering mode based on the amplitude of the noise, and to determine the noise location based on the noise characteristic parameters;

[0046] In implementation, the filter module can be selected from adaptive digital filters (FIR / IIR), RC / LC composite filters, second-order active bandpass filters, and common-mode noise suppression filters. The preferred implementation is a second-order active bandpass filter. Those skilled in the art can make adaptive substitutions for the type of filter module according to the actual application scenario or implementation environment.

[0047] The control module, which is connected to the noise monitoring module, the underground pipeline protection marker post 1, and the filtering module, is used to determine the estimated geological condition based on geological structure parameters, and to determine whether to activate the filtering module based on the estimated geological condition and the noise location.

[0048] Furthermore, the power consumption ratio of the filtering module determines whether to use the filtering results of adjacent marking devices for fitting.

[0049] The estimated geological conditions include compacted and loose states.

[0050] Specifically, the geological structure parameter = 1 / (average hardness of underground rock and soil 3 × average density of underground rock and soil 3).

[0051] Specifically, the control module is also used to determine the estimated geological state as the compacted state based on the geological structure parameters being less than the preset geological structure parameters, and to determine the estimated geological state as the loose state based on the geological structure parameters being greater than or equal to the preset geological structure parameters.

[0052] Optionally, when the underground pipeline protection marker post 1 is located at a temperature of -20℃ to 40℃ and a humidity of 30%RH to 80%RH, the preset geological structure parameters can be selected within a range of [5×10-12 (MPa·kg / m²)]. 3 )-1,5×10-11(MPa·kg / m 3 )-1].

[0053] Preferably, in this embodiment, when the underground pipeline protection marker post 1 is located at a temperature of -20℃ to 40℃ and a humidity of 30%RH to 80%RH, the preferred embodiment of the preset geological structure parameters is 1×10⁻¹¹ (MPa·kg / m²). 3 )-1.

[0054] Those skilled in the art will understand that the range of preset geological structure parameters and the preferred embodiments provided in this embodiment are the values ​​that best address the technical problem solved by the present invention at the underground pipeline protection marker post 1 under the conditions of temperature: -20℃~40℃ and humidity: 30%RH~80%RH. In actual application or implementation, those skilled in the art can make adaptive adjustments to the preset geological structure parameters according to the actual application environment and application scenario.

[0055] In practice, since the estimated geological state of the underground rock and soil body 3 varies, the degree and probability of geological deformation of the underground rock and soil body 3 under different estimated geological states will also be different. The underground pipelines in the underground rock and soil body 3 under different estimated geological states will also be affected differently. The control module determines the estimated geological state based on the geological structure parameters and determines whether the estimated geological state is compact or loose. The estimated geological state of the underground rock and soil body 3 is divided into two states, which solves the problem that the traditional monitoring strategy relies on a fixed monitoring method and cannot adapt to different estimated geological states. This improves the adaptability of the underground pipeline protection and marking device to different geological conditions.

[0056] Specifically, the control module is connected to the triaxial accelerometer 2 to determine the number of samples to be collected for the inclination angle of the underground rock and soil 3 based on the estimated geological state to which the current underground rock and soil 3 belongs, wherein the number of samples collected in the compacted state is less than the number of samples collected in the loose state.

[0057] In implementation, since the degree and probability of geological deformation of the underground rock and soil body 3 are different under different estimated geological conditions, the degree and probability of geological deformation of the underground rock and soil body 3 under the estimated geological condition of compaction is smaller than that under the estimated geological condition of looseness. The control module determines the number of samples to be collected for the inclination angle of the underground rock and soil body 3 according to the estimated geological condition to which the current underground rock and soil body 3 belongs. The number of samples collected under the compaction condition is less than that under the looseness condition, which realizes the rational allocation of resources and reduces the energy consumption of the marking device.

[0058] Specifically, the control module is connected to the triaxial accelerometer 2 and is also used to determine the detection cycle of the triaxial accelerometer 2 according to the estimated geological state to which the current underground rock and soil mass 3 belongs, wherein the detection cycle of the compacted state is longer than the detection cycle of the loose state.

[0059] In implementation, since the degree and probability of geological deformation of the underground rock and soil 3 are different under different estimated geological conditions, the degree and probability of geological deformation of the underground rock and soil 3 under the estimated geological condition of compaction is smaller than that under the estimated geological condition of looseness. The control module determines the detection cycle of the triaxial accelerometer 2 according to the estimated geological condition to which the current underground rock and soil 3 belongs. The detection cycle of the compaction state is longer than that of the looseness state, which realizes the rational allocation of resources and reduces the energy consumption of the marking device.

[0060] Specifically, the filtering module is connected to the noise monitoring module to obtain the frequency and propagation speed of the noise, and to determine the location of the noise as internal noise based on the fact that the frequency is less than a preset frequency and the propagation speed is greater than a preset propagation speed;

[0061] The noise location is determined to be external noise based on the fact that the frequency is greater than or equal to a preset frequency and the propagation speed is less than or equal to a preset propagation speed.

[0062] Those skilled in the art will understand that determining whether a noise location is internal or external noise by comparing its frequency and propagation speed with preset frequencies and propagation speeds is the most effective way to address the technical problem solved by the present invention at the underground pipeline protection marker post 1 under the conditions of temperature -20℃ to 40℃ and humidity 30%RH to 80%RH. In practical applications or implementations, those skilled in the art can make adaptive adjustments to the method according to the actual application environment and application scenario.

[0063] Optionally, when the underground pipeline protection marker post 1 is located at a temperature of -20℃ to 40℃ and a humidity of 30%RH to 80%RH, the preset frequency can be selected within the range of [80Hz, 120Hz], and the preset propagation speed can be selected within the range of [320m / s, 340m / s].

[0064] Preferably, in this embodiment, when the underground pipeline protection marker post 1 is located at a temperature of -20℃ to 40℃ and a humidity of 30%RH to 80%RH, the preferred embodiment of the preset frequency is 100Hz and the preferred embodiment of the preset propagation speed is 340m / s.

[0065] Those skilled in the art will understand that the preset frequency, the preset propagation speed selection range, and the preferred embodiment provided in this embodiment are the values ​​that best address the technical problem solved by the technical solution of this invention, selected at the underground pipeline protection marker post 1 under the conditions of temperature: -20℃~40℃ and humidity: 30%RH~80%RH. In actual application or implementation, those skilled in the art can adaptively adjust the preset frequency and preset propagation speed according to the actual application environment and application scenario.

[0066] Specifically, the control module is connected to the filtering module and is used to determine to start the filtering module based on the estimated geological state being compact and the noise location being internal noise.

[0067] Based on the fact that the noise location is external noise, the filtering module is activated.

[0068] Based on the estimated geological condition being soft and the noise location being internal noise, it is determined that the filtering module will not be activated.

[0069] In implementation, since the internal and external noise under different estimated geological conditions have different effects on the detection results of the triaxial accelerometer 2, when the estimated geological condition is soft and the noise location is internal, the propagation of internal noise through the underground rock and soil 3 under the soft geological condition is weakened, and its impact on the detection results of the triaxial accelerometer 2 is small. Therefore, the control module determines not to activate the filtering module based on the estimated geological condition being soft and the noise location being internal. When the estimated geological condition is compacted and the noise location is internal, the propagation of internal noise through the compacted geological condition is weakened, and its impact on the detection results of the triaxial accelerometer 2 is small. If the internal noise propagates normally in the compacted underground soil and rock mass 3, it has a significant impact on the detection results of the triaxial accelerometer 2. Therefore, the control module determines to activate the filtering module to filter out the noise based on the estimated geological state being compacted and the noise location being internal noise. If the noise location is external noise, the external noise has a significant impact on the detection results of the triaxial accelerometer 2. Therefore, the control module determines to activate the filtering module to filter out the noise based on the noise location being external noise. This realizes the activation and deactivation of the filtering module according to the above different conditions, reducing the energy consumption of the filtering module.

[0070] Specifically, the filtering module is connected to the noise monitoring module and is also used to determine the first filtering mode based on the noise amplitude being less than a preset amplitude threshold, and to determine the second filtering mode based on the noise amplitude being greater than or equal to the preset amplitude threshold.

[0071] The gain adjustment range of the first filtering mode is smaller than that of the second filtering mode.

[0072] Optionally, when the underground pipeline protection marker post 1 is located at a temperature of -20℃ to 40℃ and a humidity of 30%RH to 80%RH, the preset amplitude threshold can be selected within the range of [30dB, 65dB].

[0073] Preferably, in this embodiment, when the underground pipeline protection marker post 1 is located at a temperature of -20℃ to 40℃ and a humidity of 30%RH to 80%RH, the preferred embodiment of the preset amplitude threshold is 40dB.

[0074] Those skilled in the art will understand that the preset amplitude threshold range and preferred embodiment provided in this embodiment are the values ​​that best address the technical problem solved by the present invention at the underground pipeline protection marker post 1 under the conditions of temperature: -20℃~40℃ and humidity: 30%RH~80%RH. In actual application or implementation, those skilled in the art can adaptively adjust the preset amplitude threshold according to the actual application environment and application scenario.

[0075] In implementation, the control module determines the filtering mode based on the amplitude of the noise, which solves the problems of insufficient filtering capability and high energy consumption caused by the fixed filtering mode of traditional filtering modules. By adopting different filtering modes for different noise amplitudes, the filtering capability of the filtering module is improved and the energy consumption of the filtering module is reduced.

[0076] Specifically, the control module is connected to the filtering module and is also used to fit the filtering results of adjacent identification devices if the power consumption ratio of the filtering module is less than the preset ratio. The power consumption ratio of the filtering module refers to the ratio of the current power consumption of the filtering module to the current power consumption of the identification device, and the preset ratio refers to the ratio of the power required for the operation of the filtering module to the total power consumption of the identification device.

[0077] Optionally, when the underground pipeline protection marker post 1 is located at a temperature of -20℃ to 40℃ and a humidity of 30%RH to 80%RH, the preset occupancy ratio can be selected within the range of [20%, 60%].

[0078] Preferably, in this embodiment, when the underground pipeline protection marker post 1 is located at a temperature of -20℃ to 40℃ and a humidity of 30%RH to 80%RH, the preferred embodiment of the preset occupancy ratio is 30%.

[0079] Those skilled in the art will understand that the preset occupancy ratio selection range and preferred embodiment provided in this embodiment are the values ​​that best address the technical problem solved by the technical solution of the present invention, selected at the underground pipeline protection marker post 1 in this embodiment under the conditions of temperature: -20℃~40℃ and humidity: 30%RH~80%RH. In actual application or implementation, those skilled in the art can make adaptive adjustments to the preset occupancy ratio according to the actual application environment and application scenario.

[0080] In implementation, the control module uses the filtering results of adjacent signage devices to fit the filtering results of the adjacent signage devices when the power consumption ratio of the filtering module is less than the preset ratio. This solves the problem that the filtering module cannot operate and cannot filter noise when the power consumption ratio of the filtering module is less than the preset ratio, and enables the filtering module to obtain filtering results even when there is insufficient energy.

[0081] Specifically, the warning unit 102 is equipped with a light strip to display the state of geological deformation. If the tilt angle of the underground rock and soil body 3 is greater than the preset safe tilt angle, it is determined that the geological deformation is abnormal and the light strip lights up. The light strip includes several indicator lights of different colors. The indicator lights of the corresponding colors light up according to the different distances between the maintenance personnel and the underground pipeline protection marker post 1, so as to facilitate personnel to locate and deal with problems.

[0082] Optionally, when the underground pipeline protection marker post 1 is located at a temperature of -20℃ to 40℃, the preset safety tilt angle can be selected within the range of [1.5°, 5.5°].

[0083] Preferably, in this embodiment, when the underground pipeline protection marker post 1 is located at a temperature of 20℃~30℃, the preferred embodiment of the preset safety tilt angle is 3.2°.

[0084] Those skilled in the art will understand that the preferred setting of 3.2° is a preferred embodiment when the underground pipeline protection marker post 1 is located at a temperature of 20°C to 30°C. In actual application or implementation, those skilled in the art can make adaptive adjustments or replacements to the preset safety tilt angle according to the changes in the temperature conditions at which the underground pipeline protection marker post 1 is located.

[0085] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
