Description

Technical Field

[0001] The present application relates to the technical field of pipeline detection, and in particular to an environmental safety detection method applied to uneven construction areas. Background Art

[0002] The laying of underground pipelines will be applied in various regional environments. By burying the pipelines underground, the ground space can be freed up, and the soil layer buried outside the pipelines can also protect the pipelines.

[0003] During the burial process, part of the soil in contact with the bottom of the pipeline is compacted. Looking at the entire underground pipeline network, the thickness of the rammed earth layer is not evenly distributed, and there are differences in the soil texture at the bottom of the rammed earth layer. After the underground pipeline is used for a long time, there may be misalignment between two adjacent pipelines, thus causing leakage.

[0004] In the flat paved area, when one or several sections of the underground pipeline are greatly offset or settled, the paved ground will sink or bulge. Observers can infer whether the underground pipeline has a large misalignment by observing the flatness of the paved ground. However, after the underground pipeline has been used for a long time, the ground above the underground pipeline is mostly rugged except for the flat paved area. This is particularly obvious in uneven areas with large slopes. It is not advisable to rely on observing whether the ground above the underground pipeline is flat to infer the working condition of the pipeline below.

[0005] In the prior art, pipeline inspections are seldom performed except when a leak has occurred and is visible on the ground, because direct inspection by excavation is labor-intensive. When an excavator is used for excavation, the bucket teeth of the excavator can easily touch the pipeline and cause damage to the pipeline. After the pipeline is exposed, the probability of landslides on the slopes on both sides is uncertain, which will significantly reduce the safety of operators during inspections.

[0006] Therefore, there is a need for a highly efficient, trenchless underground pipeline safety detection method that can be used in uneven construction area environments. Summary of the invention

[0007] In view of the shortcomings of the prior art, the present application provides an environmental safety detection method for uneven construction areas. By using a control group, by comparing the relative positions of two pipelines to be detected with a standard control group, it is possible to quickly detect whether the positional relationship between two adjacent pipes in an underground pipeline in an uneven area meets the requirements, thereby significantly improving the detection efficiency of pipelines in uneven areas and significantly improving the safety factor of operators and pipelines.

[0008] The above application objectives of this application are achieved through the following technical solutions:

The shape and outer diameter of the extension area of ​​the standard pipe are consistent with those of the standard pipe, and the shape and position relationship between the standard pipe and the extension area is consistent with the shape and position relationship between the two pipes to be measured.

[0012] In response to the acquired characteristic signals of several locators on the standard pipeline, the area where the standard pipeline is located and the extended area are divided into a detection area to form a standard control group, wherein the detection area includes the outer area and the inner area of ​​the annular cylindrical area where the outer side surface of the standard pipeline is located, and the outer area and the inner area of ​​the annular cylindrical area where the outer side surface of the extended area of ​​the standard pipeline is located;

[0013] The detector group is arranged outside the first pipeline to be tested, and at least three positioners are arranged on the outer surface of the first pipeline to be tested, and the relative position of the detector group and the first pipeline to be tested is consistent with the relative position of the detector group and the standard pipeline;

[0014] In response to the acquired current characteristic signals of the plurality of locators on the first pipeline to be tested, a detection zone of the current extension area of ​​the first pipeline to be tested is divided, the positional relationship between the first pipeline to be tested and the extension area of ​​the first pipeline to be tested is the same as the positional relationship between the standard pipeline and the extension area of ​​the standard pipeline, the shape and diameter of the extension area of ​​the first pipeline to be tested are the same as the shape and diameter of the extension area of ​​the standard pipeline, and the detection zone of the extension area of ​​the first pipeline to be tested includes an outer area and an inner area of ​​the annular cylindrical area where the outer side surface of the extension area of ​​the first pipeline to be tested is located;

[0015] A locator is arranged on the outer side of the second pipeline to be tested;

[0016] In response to the acquired current characteristic signals of the plurality of locators on the second pipeline to be tested, determining whether the locators on the outer surface of the second pipeline to be tested are within the detection area of ​​the extension area of ​​the first pipeline to be tested;

[0017] Based on the standard control group, it is determined whether the first pipeline to be tested is aligned with the second pipeline to be tested.

[0018] In summary, this application has the following beneficial technical effects:

[0026] The present application is further described in detail below in conjunction with the accompanying drawings.

[0027] The present application provides a method for detecting environmental safety in a non-level construction area, comprising the following steps:

[0028] S101, setting a detector group outside a standard pipe, wherein the outer diameter and the outer diameter of the standard pipe are consistent with those of the pipe to be tested, and the setting position of the detector group is at a certain distance from the outer cylindrical surface of the standard pipe;

[0031] S104, setting a detector group outside the first pipeline to be tested, and setting at least three positioners on the outer surface of the first pipeline to be tested, wherein the relative position of the detector group and the first pipeline to be tested is consistent with the relative position of the detector group and the standard pipeline;

[0032] S105, obtaining current characteristic signals of a plurality of locators on the first pipeline to be tested, and dividing a detection zone of an extension area of ​​the current first pipeline to be tested;

[0033] S106, setting a positioner on the outer side of the second pipeline to be tested;

[0034] S107, in response to the acquired current characteristic signals of the plurality of locators on the second pipeline to be tested, determining whether the locators on the outer surface of the second pipeline to be tested are within the detection area of ​​the extension area of ​​the first pipeline to be tested;

[0035] S108: Determine whether the first pipeline to be tested is aligned with the second pipeline to be tested.

[0036] The following is a further introduction based on specific usage scenarios.

[0037] First of all, it should be noted that in actual use scenarios, the shape of the pipe is quite varied, but the most common pipe shape is a straight pipe. In the embodiment of the present application, the case where the pipe to be detected is a straight pipe is taken as an example. Pipes of other shapes can also be detected according to the method provided in the embodiment of the present application;

[0038] In actual usage scenarios, the positional relationship between the two pipes, that is, the angle of the central axes of the two pipes will be adjusted according to the specific usage scenarios. Generally, there are two situations: the central axes of the two pipes are collinear and the central axes of the two pipes are in the same plane but have an angle between them. The embodiment of the present application first takes the situation where the central axes of the two pipes are collinear as an example;

[0039] In actual usage scenarios, the positioning methods include received signal strength positioning method (RSSI) and arrival time difference method (TDOA), etc. The embodiment of the present application first takes the case of RSSI-based positioning algorithm as an example;

[0040] First, execute step S101, such as Figure 1 As shown, a detector group is arranged outside a standard pipe, the shape and outer diameter of the standard pipe are consistent with those of the pipe to be tested, the arrangement position of the detector group is at a certain distance from the outer cylindrical surface of the standard pipe, and the detector group can have the function of sending and receiving radio signals;

[0041] Then, step S102 is performed, such as Figure 2As shown, a number of locators are arranged on the outer surfaces of the standard pipe and its extension area, and the locators can have the function of sending and receiving radio signals. The shape and outer diameter of the extension area are consistent with those of the standard pipe, and the shape and position relationship between the standard pipe and the extension area is consistent with the shape and position relationship between the two pipes to be measured. The locators and the detector group can communicate wirelessly;

[0042] In step S103, Figure 3 As shown, the locator receives several wireless signals from the detector group to form a specific receiving strength sequence in the current state, which is also the characteristic signal of the locator. The receiving strength sequence of each locator among several locators is different. According to the characteristic signals of several locators on the standard pipeline, the area where the standard pipeline is located and the extended area are divided into detection areas;

[0043] It should be understood that after the detector group sends out a wireless signal, the locator receives several AP signals to form a unique receiving strength sequence. The relative position of the locator can be inferred according to the installation position of the detector group. The locators are distributed on the outer side of the standard pipe and the outer side of the extended area. The positions of several locators determined according to the receiving strength sequence should be distributed in the annular cylindrical area where the outer side of the standard pipe is located, and should not appear outside the aforementioned annular cylindrical area and inside the aforementioned annular cylindrical area. In the embodiment of the present application, the aforementioned annular cylindrical area is defined as a non-detection area, and the outer side of the aforementioned annular cylindrical area and the inner area of ​​the aforementioned annular cylindrical area are defined as a detection area. The detection area division on the extended area of ​​the standard pipe is consistent with the detection area division method of the standard pipe.

[0044] Then, step S104 is executed. The pipelines to be tested include a first pipeline to be tested and a second pipeline to be tested. The result to be tested is whether the shape and position relationship between the first pipeline to be tested and the second pipeline to be tested meets the requirements. The detector group is installed on the outside of the first pipeline to be tested in the same position relationship as the standard pipeline, and at least three positioners are arranged on the outer surface of the first pipeline to be tested. Figure 4 As shown, the detector group installed on the outside and the outer surface of the first pipeline to be tested communicates wirelessly with the locator;

[0045] In the actual detection process, a drill rod can be used to drill holes in the area to be detected, and then the detector group and several locators are installed in the required positions;

[0046] Then, step S105 is executed, wherein a plurality of locators installed on the outer surface of the first pipeline to be tested receive a plurality of AP signals of the detector group outside the first pipeline to be tested, forming a specific receiving strength sequence, and the current positions of the plurality of locators on the first pipeline to be tested are determined according to the receiving strength sequence of each locator installed on the outer surface of the first pipeline to be tested. When the outer diameter of the first pipeline to be tested is known, at least three locators installed on the outer surface of the first pipeline to be tested can determine the relative position between the current first pipeline to be tested and the detector group;

[0047] like Figure 5 As shown, based on the known outer diameters of the first pipeline to be tested and the extension area, the detection area of ​​the extension area of ​​the first pipeline to be tested is divided, and the extension area of ​​the first pipeline to be tested is also the expected area of ​​the second pipeline to be tested;

[0048] In step S106, a locator is arranged on the outer side of the second pipeline to be tested, and the locator arranged on the outer side of the second pipeline to be tested may be one or more;

[0049] In the actual detection process, a drill rod can be used to drill a hole in the area to be detected, and then the locator can be installed in the required position;

[0050] Then, step S107 is executed. After the locator on the outer surface of the second pipeline to be tested is installed, the locator on the outer surface of the second pipeline to be tested receives a number of AP signals of the detector group outside the first pipeline to be tested to form a specific receiving intensity sequence. The position of the locator is determined according to the receiving intensity sequence of the locator on the second pipeline to be tested, and it is determined whether the locator is in the detection area of ​​the extension area of ​​the first pipeline to be tested.

[0051] Finally, step S108 is performed to determine whether the first pipeline to be tested is aligned with the second pipeline to be tested based on the area where the locator on the second pipeline to be tested is located. That is, when the locator on the second pipeline to be tested is in the detection area of ​​the extension area of ​​the first pipeline to be tested, if Figure 6 As shown, it is determined that the locator on the second pipe to be tested deviates from the expected area of ​​the second pipe to be tested, thereby determining that the second pipe to be tested deviates from the predetermined area. When the locator on the second pipe to be tested is in the non-detection area of ​​the extension area of ​​the first pipe to be tested, it is determined that the locator on the second pipe to be tested is in the expected area of ​​the second pipe to be tested, thereby determining that the second pipe to be tested is aligned with the first pipe to be tested.

[0052] It should be understood that in the embodiment of the present application, the installation distance between the locator and the standard pipeline, the first pipeline to be tested and the second pipeline to be tested is consistent. When the positional relationship between the first pipeline to be tested and the second pipeline to be tested meets the requirements, that is, the positional relationship between the first pipeline to be tested and the second pipeline to be tested is consistent with the positional relationship between the standard pipeline and the extended area of ​​the standard pipeline, the locator installed on the second pipeline to be tested should not appear in the detection area of ​​the extended area of ​​the first pipeline to be tested, that is, the locator on the second pipeline to be tested should appear in the expected area of ​​the second pipeline to be tested.

[0053] It can be found that in the embodiments of the present application, the condition of underground pipelines in uneven areas can be inspected without the need for excavation, which significantly improves the inspection efficiency of pipelines, and the trenchless inspection method significantly improves the safety factor of operators and pipelines.

[0054] In general, the embodiment of the present application uses a control group to compare the relative positions of the two pipes to be inspected with the standard control group, so as to quickly detect whether the positional relationship between two adjacent pipes in the underground pipeline in the uneven area meets the requirements, thereby significantly improving the inspection efficiency of the pipeline in the uneven area and significantly improving the safety factor of the operators and the pipeline.

[0055] It should be noted that when the non-flat construction area involved in the specific usage scenario of the embodiment of the present application is a slope with a certain slope, it is sufficient to ensure that the relative position between the detector group and the first pipeline to be tested and the relative position between the detector group and the standard pipeline remain consistent.

[0056] In actual usage scenarios, the positional relationship between the two pipes, that is, the angle of the central axes of the two pipes will be adjusted according to the specific usage scenarios, and is generally divided into two situations: the central axes of the two pipes are collinear and the central axes of the two pipes are in the same plane but have an angle between them. When there is an angle between the central axes of the two pipes to be tested, the relative positions of the standard pipe and the extended area of ​​the standard pipe should be arranged in steps S101-S103 to be the same as the relative positions of the two pipes to be tested, so that the extended area of ​​the standard pipe, that is, the detection area of ​​the expected position of the other pipe, is consistent with the actual application scenario. The method provided in the embodiment of the present application can also be applied to the situation where there is an angle between the central axes of the two pipes to be tested.

[0057] In actual usage scenarios, when using the RSSI positioning algorithm, in steps S101-S103, soil can be filled between the detector group and the standard pipe and its extension area to make the AP signal attenuation coefficient received by the locator closer to the actual usage scenario. Of course, the above steps are not required when using the arrival time difference method for positioning.

[0058] When using the TDOA positioning algorithm, the steps are the same as above, except that the characteristic signal of the locator is no longer a reception intensity sequence, but a time difference received by the detector group after the locator broadcasts. Since the detection area of ​​the detection pipeline is small, the use of the TDOA positioning algorithm is also applicable to the method provided in the embodiment of the present application.

[0059] As a feasible specific implementation method of the embodiment of the present application, a plurality of positioners are arranged on the outer surface of the standard pipe and its extension area, including:

[0060] S201, dividing a plurality of groups of positioning areas on the outer surface of the standard pipe and its extended area, wherein the plurality of groups of positioning areas are linearly arranged at equal intervals along the central axis of the standard pipe and its extended area, each group of positioning areas includes a plurality of positioning areas in an annular array, and the plurality of groups of positioning areas form a non-detection area in the shape of an annular cylinder;

[0061] S202, independently installing a plurality of positioners in the middle of each positioning area.

[0062] In combination with a specific usage scenario, when in use, several groups of positioning areas are arranged in step S201, and several positioning areas are evenly distributed on the outside of the standard pipe. Several locators are respectively installed in the middle of each positioning area, which can more accurately collect the position information near the outer side of the standard pipe and its extended area, thereby more accurately dividing the collection area of ​​the standard pipe and its extended area.

[0063] As a feasible specific implementation of the embodiment of the present application, the detector group includes a plurality of detectors, and at least one detector is not coplanar with the other detectors.

[0064] In combination with a specific usage scenario, obtaining the specific location of a certain locator depends on the wireless communication between the locator and several detectors in the detector group. Taking RSSI positioning as an example, the locator receives the wireless signals of several detectors in the detector group to form a specific receiving strength sequence, so as to determine the location of the locator.

[0065] In the embodiment of the present application, since at least one detector is not coplanar with the other detectors, assuming that the other detectors in the detection group are in the same plane, when one detector is not in the aforementioned plane, when the aforementioned plane is taken as the symmetry plane, the receiving intensity sequences of the two locators symmetrical about the aforementioned symmetry plane are not the same, thereby improving the positioning accuracy of the detector for the locator.

[0066] As a feasible specific implementation method of the embodiment of the present application, the following steps are also included:

[0067] S301, using the current detector group as a reference, determining the current position of the first pipeline to be tested;

[0068] S302: Adjust the relative position of the detector group with respect to the first pipeline to be tested based on the current position of the first pipeline to be tested.

[0069] In combination with a specific usage scenario, the embodiment of the present application uses a standard pipeline and its extended area as a standard group, and collects the position information of the two pipelines to be tested and compares it with the standard group to determine whether the position relationship between the two pipelines to be tested meets the requirements;

[0070] A detector group is set outside the standard pipeline of the standard group. After completing the data collection of the standard group, the operator performs the detection of the actual pipeline to be tested. The operator needs to install the detector group outside the first pipeline to be tested;

[0071] In this process, the detector group and the locator are first installed. At this time, the installation position of the detector group is not required. Then, the characteristic signals of several locators set on the outside of the first pipeline to be tested are obtained to determine the positions of the several locators on the outside of the first pipeline to be tested. Since the outer diameter of the pipeline is known, it is easy to judge the position of the first pipeline to be tested relative to the detector group. At this time, the position of the detector group can be adjusted based on the first pipeline to be tested and the several locators on the outside of the first pipeline to be tested, so that the position of the detector group relative to the first pipeline to be tested is close to the position of the detector group relative to the standard pipeline, thereby improving the positioning accuracy of the detector to the locator.

[0072] In a feasible specific implementation of the embodiment of the present application, determining the current location of the first pipeline to be tested includes:

[0073] S401, selecting a projection plane perpendicular to the central axis of the first pipeline to be tested;

[0074] S402, analyzing current characteristic signals of a plurality of locators on the first pipeline to be tested, and obtaining current positions of the plurality of locators on the first pipeline to be tested;

[0075] S403, projecting a plurality of locator position points on the first pipeline to be measured onto the projection plane;

[0076] S404: Determine the current position of the first pipeline to be measured based on a plurality of locator projection points on the projection plane.

[0077] In combination with a specific usage scenario, at least three locators are distributed on the outer surface of the first pipeline to be tested. First, step S401 is performed. When the diameter of the pipeline to be tested is known, a projection plane perpendicular to the central axis of the first pipeline to be tested is selected. The first pipeline to be tested can be cut with the above-mentioned projection plane to obtain an annular cutting plane of the first pipeline to be tested, and the projection of the outer side profile of the first pipeline to be tested on the projection plane can also be obtained;

[0078] In step S402 and step S403, based on the acquired current position of the locator, the position of the locator is projected onto the aforementioned projection plane, and three position points can be obtained on the projection plane;

[0079] Then, step S404 is executed. When the diameter of the pipeline to be measured is known, the relative position of the current first pipeline to be measured can be obtained by taking the determined diameter of the first pipeline to be measured and three position points passing through the outer side contour line of the pipeline to be measured as known conditions.

[0080] In a feasible specific implementation of the embodiment of the present application, taking the RSSI method as an example, the step S402 of obtaining the current positions of the plurality of locators on the first pipeline to be tested includes:

[0081] S4011, taking the standard pipeline and its extension area as the standard control group, recording the current characteristic signals and positions of several locators on the standard pipeline and its extension area, wherein the current characteristic signal of the locator is a receiving intensity sequence;

[0082] S4012, comparing current characteristic signals of a plurality of locators on the first pipeline to be tested with characteristic signals of a plurality of locators on the standard pipeline;

[0083] S4013, respectively obtaining the positions of the standard pipeline locators closest to the characteristic signals of several locators on the first pipeline to be tested. Exemplarily, this step may use a K-nearest neighbor algorithm to quickly obtain the closest positioning area of ​​a certain locator set on the outer surface of the first sensor to be tested;

[0084] S4014: Use the acquired position of the standard pipeline locator as the position of the locator on the first pipeline to be tested.

[0085] Through the above steps, the current position of the first pipeline to be tested can be quickly calculated, which improves the efficiency of the entire detection process as a whole.

[0086] As a feasible specific implementation method of the embodiment of the present application, dividing the area where the standard pipeline is located and the extended area into the detection area includes the following steps:

[0087] S501, recording current characteristic signals and positions of several locators on the standard pipeline and its extended area, wherein the standard pipeline and its extended area are located in an annular columnar area outside the standard pipeline and its extended area, and the inner side of the annular columnar area is the outer side of the standard pipeline and its extended area;

[0088] S502, dividing the annular cylindrical area where the plurality of locators on the standard pipeline are located as a non-detection area, where the non-detection area is the position where the locator position signal should appear, or the position where the locator should appear calculated based on the locator characteristic signal;

[0089] S503, dividing the annular cylindrical area where a plurality of positioners are located on the extension area of ​​the standard pipeline into a non-detection area;

[0090] S504: Divide other areas outside the annular cylindrical area into a detection area, where the detection area is an area where no locator signal should appear under a standard state.

[0091] By dividing the standard pipeline and its extension area through the above steps, the expected position between the two pipelines to be inspected can be quickly calculated.

[0092] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
