For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.
In order to facilitate understanding of the technical scheme of the embodiment of the invention, first, detection in pipeline magnetic leakage is briefly described.
The pipeline magnetic leakage inner detection is completed through a pipeline magnetic leakage inner detector, and the working principle of the pipeline magnetic leakage inner detector is that magnetic force lines generated by strong magnets carried by the pipeline magnetic leakage inner detector are coupled into the pipeline wall through steel brushes, and a longitudinal magnetic loop field is generated on the whole circumference of the pipeline, so that the pipeline wall between the magnets reaches a magnetic saturation state. If the tube wall is free from defects, the magnetic force lines are uniformly distributed in the tube wall. If the pipeline has defects, the cross section of the pipeline wall is reduced, and the magnetic permeability of the defect part in the pipeline wall is far smaller than that of the ferromagnetic material, so that the magnetic resistance of the defect part is increased, the magnetic flux path is narrowed, the magnetic force lines are deformed, part of the magnetic force lines penetrate through two sides of the pipeline wall to generate a leakage magnetic field, and the shape of the leakage magnetic field depends on the geometric shape of the defect. The magnetic leakage signal is detected by a sensor which is positioned between the two magnetic poles and clings to the pipe wall, and corresponding induction signals are generated, and the signals are recorded in a memory of the detector after being processed by filtering, amplifying, analog-digital conversion and the like. After the detection is finished, the information such as the position, the type, the shape, the size and the like of the defect can be obtained by replaying, identifying and judging the data through debugging software of the pipeline magnetic flux leakage detector.
In the operation site of pipeline excavation, through ground measurement, after determining the position of a target girth weld needing to be excavated, pipeline excavation operation is carried out immediately, when the top of a pipeline is excavated, the girth weld to be excavated actually can be seen, and then by the girth weld determining method provided by the embodiment of the application, whether the girth weld to be excavated actually is the target girth weld needing to be excavated can be determined under the condition that only the top of the pipeline is excavated, and the determination is carried out after the whole circumference of the girth weld is excavated. For convenience of description, in the embodiments of the present application, this girth weld to be actually excavated is referred to as an actually excavated girth weld, that is, a first girth weld in the embodiments described below.
In addition, it should be noted that, in the actual engineering, the positional relationship between the pipe weld and the weld is described in an upstream and a downstream manner, and in the embodiment of the present application, for convenience of description, the positional relationship between the pipe weld and the weld is described in a left and a right manner to avoid ambiguity.

The computer equipment acquires second pipeline information, wherein the second pipeline information comprises trend information of spiral welding seams at two sides of a target girth weld and distance information from the target girth weld to the spiral welding seams at two sides, and the target girth weld is the girth weld needing excavation.
103. And the computer equipment matches the first pipeline information with the second pipeline information to obtain a first matching result.
104. And the computer equipment responds to the first matching result to meet a first target condition, and determines the first girth weld as a target girth weld.
In the embodiment of the application, a method for determining a girth weld is provided, wherein in the process of excavating the girth weld, pipeline information of the two girth welds can be respectively obtained for the girth weld which is actually excavated and the girth weld which is required to be excavated, and then the pipeline information of the two girth welds is matched to determine whether the girth weld which is actually excavated is the girth weld which is required to be excavated. In the process of excavating the girth weld, whether the girth weld actually excavated is the girth weld to be excavated is judged in time, so that the accuracy of excavating the girth weld is improved, and unnecessary economic loss is avoided.

In the embodiment of the application, the pipeline information is used for representing the pipeline characteristics of the girth weld, and comprises the trend of spiral weld lines at two sides of the girth weld and the distance from the girth weld line to the spiral weld lines at two sides. In practical engineering, the pipeline is obtained by connecting a plurality of pipes in a welding mode, each pipe is provided with a spiral welding seam, and a butt joint welding seam between the pipes is the girth welding seam in the embodiment of the application.

Referring specifically to fig. 3, O is a distance value between the first girth weld and the nearest spiral weld on the left side of the first girth weld, and P is a distance value between the first girth weld and the nearest spiral weld on the right side of the first girth weld. It should be noted that, in the embodiment of the present application, the distance value is obtained by taking the midpoint position of the first girth weld as the starting point, where the midpoint position is actually at the 12-point position on the top of the pipeline, and correspondingly, the end positions on the spiral weld on both sides are also at the 12-point position on the top of the pipeline, as shown in fig. 3, and in some embodiments, the calculation of the distance value can take any position of the first girth weld as the starting point, that is, the position is at any position on the top of the pipeline, and the calculation mode of the distance value in the embodiment of the present application is not limited specifically.

In actual engineering, when the top of the pipeline is excavated, the trend of the spiral weld joints at the two sides of the first girth weld joint can be identified, and then a measuring tool is used for measuring the distance value from the first girth weld joint to the spiral weld joints at the two sides at the top of the pipeline. For example, when an engineer digs out the top of a pipeline, identifying that the trend of spiral welds on two sides of a first girth weld is parallel, and simultaneously measuring by using a tape to obtain a distance value from the first girth weld to the spiral welds on two sides, wherein the distance value is measured at 12 points on the top of the pipeline to obtain two distance values of 50cm and 70cm respectively, and then inputting the obtained trend information and distance information on a pipeline information interface displayed by computer equipment.
202. The method comprises the steps that a computer device obtains the girth weld number of a target girth weld, wherein the target girth weld is the girth weld needing to be excavated.
In an embodiment of the application, each girth weld in the pipe has a fixed girth weld number. Optionally, a pipeline operation maintenance system is operated on the computer equipment, and is used for monitoring the operation state of a pipeline, when a certain section of pipeline fails, the pipeline operation maintenance system can timely locate the position of the failed pipeline, and the girth weld number corresponding to the section of pipeline is displayed, for example, the girth weld number of the target girth weld is A10.
Optionally, in actual engineering, periodic detection work needs to be performed on girth welds in the pipeline, for girth welds needing periodic detection, the girth weld numbers of the girth welds are recorded to obtain a girth weld list to be detected, and the computer equipment obtains the girth weld number of the target girth weld based on the girth weld list.
The method for acquiring the girth weld number of the target girth weld is not particularly limited in the embodiment of the application.
203. Based on the girth weld number, the computer equipment acquires the detection data in the magnetic leakage of the target girth weld.
In the embodiment of the application, the intra-magnetic leakage detection data is obtained by processing the detection data through pipeline intra-magnetic leakage detector debugging software after pipeline intra-magnetic leakage detection, wherein the intra-magnetic leakage detection data of the target girth weld is provided on an intra-magnetic leakage detection signal page, and the intra-magnetic leakage detection signal page displays an intra-magnetic leakage detection signal diagram of the target girth weld, and specifically referring to fig. 4, two possible intra-magnetic leakage detection signal diagrams of the target girth weld are given in fig. 4.
Optionally, the computer device is associated with a leakage detection database, the computer device uses the acquired circumferential weld number of the target circumferential weld as an index, the leakage detection data of the target circumferential weld is queried in the leakage detection database, a leakage detection signal page of the target circumferential weld is obtained, and a leakage detection signal diagram of the target circumferential weld is displayed on the leakage detection signal page.
204. And the computer equipment determines trend information of spiral welding seams at two sides of the target girth weld based on the detection data in the magnetic flux leakage.
In the embodiment of the application, the computer equipment identifies the trend information of the spiral weld joints at the two sides of the target girth weld joint from the magnetic flux leakage internal detection signal diagram displayed on the magnetic flux leakage internal detection signal page based on the acquired magnetic flux leakage internal detection data, namely the magnetic flux leakage internal detection signal page of the target girth weld joint. The trend information of the spiral weld seams at the two sides of the target girth weld refers to that the trend of the spiral weld seams at the two sides of the target girth weld is parallel or opposite. Referring specifically to fig. 4, fig. 4 shows two trend conditions of spiral welds on two sides of a target girth weld, where C 'is the target girth weld, D' is the spiral weld, as shown in the left diagram in fig. 4, the trend of spiral welds on two sides of the target girth weld is a parallel trend, and as shown in the right diagram in fig. 4, the trend of spiral welds on two sides of the target girth weld is an opposite trend.
205. The computer equipment determines the distance information from the target girth weld to the spiral weld on both sides based on the detection data in the magnetic flux leakage.

The distance information from the target girth weld to the spiral weld on two sides refers to two distance values obtained by taking the target girth weld as a starting point and taking two nearest spiral welds on two sides of the target girth weld as end points respectively. Referring specifically to fig. 4, E is a distance value between the target girth weld and the nearest spiral weld on the left side of the target girth weld, and F is a distance value between the target girth weld and the nearest spiral weld on the right side of the target girth weld. It should be noted that, in the embodiment of the present application, the calculation of the distance value uses the midpoint position of the target girth weld as the starting point, where the midpoint position is actually at the 12-point position on the top of the pipeline, and the corresponding end position on the two side spiral weld is also at the 12-point position on the top of the pipeline, as shown in fig. 4, and in some embodiments, if the distance value from the first girth weld to the two side spiral weld uses any position of the first girth weld as the starting point, that is, the position is at any position on the top of the pipeline, then in this step, when calculating the distance value from the target girth weld to the two side spiral weld, the starting point position on the target girth weld should be the same as the starting point position on the first girth weld.

The method for acquiring the detection mileage value in the magnetic leakage of the target girth weld and the spiral weld on two sides is not particularly limited.
Referring to fig. 4, H is the intra-leakage detection mileage of the target girth weld in the 12-point position at the top of the pipeline, G is the intra-leakage detection mileage of the spiral weld at the left side of the target girth weld in the 12-point position at the top of the pipeline, and I is the intra-leakage detection mileage of the spiral weld at the right side of the target girth weld in the 12-point position at the top of the pipeline.
Step two: the computer equipment determines the distance information from the target girth weld to the spiral weld on the basis of the internal magnetic leakage detection mileage value of the target girth weld and the internal magnetic leakage detection mileage value of the spiral weld on both sides of the target girth weld.
Referring to fig. 4, an implementation manner of this step is described, where E is a distance value between the target circumferential weld and the spiral weld closest to the left side of the target circumferential weld, and is obtained by subtracting the leakage flux inner detection mileage value G of the spiral weld on the left side of the target circumferential weld from the leakage flux inner detection mileage value H of the target circumferential weld, that is, e=h-G. In the figure, F is a distance value between the target girth weld and the spiral weld closest to the right side of the target girth weld, and is obtained by subtracting the intra-leakage detection mileage value H of the target girth weld from the intra-leakage detection mileage value I of the spiral weld on the right side of the target girth weld, that is, f=i-H.
It should be noted that, in the embodiment of the present application, the computer device performs the step 204 first, and then performs the step 205. In an alternative implementation, the computer device performs step 204 and step 205 described above simultaneously. In another alternative implementation, the computer device performs step 205 described above before performing step 204 described above. The execution sequence of the above steps 204 and 205 is not particularly limited in the embodiment of the present application.
206. The computer device obtains second pipeline information based on the distance information from the target girth weld to the two-side spiral weld and the distance information from the target girth weld to the two-side spiral weld.
In the embodiment of the present application, the computer device executes the steps 201 to 206 in the order from front to back, that is, the computer device acquires the first pipeline information first and then acquires the second pipeline information. In an alternative implementation, the computer device performs steps 202 to 206 in the order from front to back, and then performs step 201, that is, the computer device acquires the second pipeline information first and then acquires the first pipeline information. The order of acquiring the first pipeline information and the second pipeline information is not particularly limited in the embodiment of the present application.
207. And the computer equipment matches the first pipeline information with the second pipeline information to obtain a first matching result.
In the embodiment of the application, the first matching result comprises whether the trend of the spiral weld at the two sides of the first girth weld is consistent with the trend of the spiral weld at the two sides of the target girth weld, and an error value between the distance value from the first girth weld to the spiral weld at the two sides and the distance value from the target girth weld to the spiral weld at the two sides.
Two cases of the first matching result in this step are illustrated below with reference to fig. 3 and fig. 4 provided in the embodiment of the present application:
Case one: taking the left diagram in fig. 3 as an example, the directions of spiral welds on two sides of the first girth weld in the diagram are parallel; the distance values from the first girth weld to the spiral weld at two sides are O and P respectively, taking a left diagram in fig. 4 as an example, wherein the trend of the spiral weld at two sides of the target girth weld in the diagram is parallel; the distance values from the target girth weld to the spiral weld on both sides are E and F respectively. The first matching result obtained by the computer equipment at this time is: the trend of the spiral weld at two sides of the first girth weld is consistent with the trend of the spiral weld at two sides of the target girth weld, and the error value between the distance value from the first girth weld to the spiral weld at two sides and the distance value from the target girth weld to the spiral weld at two sides is E minus O and F minus P respectively.
And a second case: taking the left diagram in fig. 3 as an example, the directions of spiral welds on two sides of the first girth weld in the diagram are parallel; the distance values from the first girth weld to the spiral weld at two sides are O and P respectively, taking the right diagram in fig. 4 as an example, the trend of the spiral weld at two sides of the target girth weld in the diagram is opposite; the distance values from the target girth weld to the spiral weld on both sides are E and F respectively. The first matching result obtained by the computer equipment at this time is: the trend of the spiral weld at two sides of the first girth weld is inconsistent with the trend of the spiral weld at two sides of the target girth weld, and the error value between the distance value from the first girth weld to the spiral weld at two sides and the distance value from the target girth weld to the spiral weld at two sides is E minus O and F minus P respectively.
208. The computer device determines, according to the first matching result, whether the first matching result meets a first target condition, if so, performs step 209, and if not, performs steps 210 to 213.
In the embodiment of the present application, the first matching result meeting the first target condition means that: the trend of the spiral weld at the two sides of the first girth weld is consistent with the trend of the spiral weld at the two sides of the target girth weld, and the error value between the distance value from the first girth weld to the spiral weld at the two sides and the distance value from the target girth weld to the spiral weld at the two sides meets a preset threshold.
The following describes that the first matching result in this step meets the first target condition:
In the first scenario where the first matching result in step 207 is the case one, the trend of the spiral weld at both sides of the first girth weld is consistent with the trend of the spiral weld at both sides of the target girth weld, the computer device obtains two error values of E minus O and F minus P by calculation, compares the two error values with a preset threshold after taking absolute values, and determines that the error value between the distance value from the first girth weld to the spiral weld at both sides and the distance value from the target girth weld to the spiral weld at both sides meets the preset threshold when the absolute values of the two error values are smaller than the preset threshold, wherein, the absolute value of the error value meeting the preset threshold is equal to or smaller than the preset threshold. For example, the preset threshold is 10cm, the absolute values of the two error values obtained by calculation by the computer device are 3cm and 4cm respectively, and are smaller than the preset threshold of 10cm, and the computer device determines that the two error values meet the preset threshold. At this point the computer device determines that the first matching result meets the first target condition. It should be noted that, the setting of the preset threshold and the determination manner of whether the error value meets the preset threshold in the embodiment of the present application are not limited in particular.
The following describes that the first matching result in this step does not meet the first target condition, and specifically there are the following two cases:
Case one: the trend of the spiral weld at the two sides of the first girth weld is inconsistent with the trend of the spiral weld at the two sides of the target girth weld, and at the moment, the computer equipment determines that the first matching result does not accord with the first target condition.
And a second case: the trend of the spiral weld at the two sides of the first girth weld is consistent with the trend of the spiral weld at the two sides of the target girth weld, but the error value between the distance value from the first girth weld to the spiral weld at the two sides and the distance value from the target girth weld to the spiral weld at the two sides does not meet the preset threshold. The method for determining whether the error value satisfies the preset threshold is similar to the above method, and thus will not be described herein.
209. The computer device determines the first girth weld as the target girth weld.
In the embodiment of the application, when the first matching result meets the target condition, the computer equipment determines that the first girth weld is the target girth weld.
Through the steps 201 to 209, in the process of excavating the pipeline, when the upper half part of the pipeline is excavated, whether the girth weld to be excavated is judged in time, so that the phenomenon that the excavated girth weld is the wrong girth weld after the excavation operation of the girth weld is completed is avoided, the accuracy of excavating the girth weld is improved, and unnecessary economic loss is avoided.
In addition, in the embodiment of the present application, after the step 208, when the computer device determines that the current first girth weld is not the target girth weld, the following steps 210 to 213 are performed, and the pipe information of at least one third girth weld located in the adjacent position of the target girth weld is identified and analyzed one by one until a third girth weld matching the first girth weld actually excavated is found, and then the position of the target girth weld is redetermined with reference to the position information of the third girth weld. The following describes steps 210 to 213 in detail:
210. The computer device obtains at least one third pipeline information, wherein the third pipeline information comprises trend information of spiral welding seams at two sides of a third girth weld and distance information from the third girth weld to the spiral welding seams at two sides, and the third girth weld is a girth weld which is adjacent to the target girth weld.
In the embodiment of the application, the computer equipment acquires the girth weld number of at least one third girth weld, acquires the magnetic flux leakage internal detection data of the at least one third girth weld based on the acquired girth weld number, and then acquires the at least one third pipeline information based on the acquired magnetic flux leakage internal detection data. It should be noted that, the specific method for the computer device to obtain the at least one third pipeline information is similar to the method for obtaining the second pipeline information in the steps 203 to 206, so that the detailed description is omitted herein.
In this step, the third girth weld is a girth weld located adjacent to the target girth weld, which means that the third girth weld is a girth weld on both left and right sides of the target girth weld.
Optionally, the girth weld numbers of the girth welds in the pipeline are continuously arranged according to the position sequence of the girth welds, and the computer device can obtain the number of at least one third girth weld based on the girth weld number of the target girth weld. For example, the girth weld number of the target girth weld is a10, and the girth weld numbers of the nearest girth welds located on the left and right sides of the target girth weld are a09 and a11. Referring to fig. 5, in the drawing, a10 is a target girth weld, and a09 and a11 are both third girth welds, and then the computer device obtains the pipe information of the two third girth welds a09 and a11, that is, the two third pipe information, respectively. It should be noted that, fig. 5 only schematically shows the positional relationship of three girth welds and the girth weld numbers, in actual engineering, the pipe information of a plurality of third girth welds can be obtained according to the requirements, that is, the pipe information is obtained one by one for a plurality of girth welds on the left and right sides of the target girth weld with the target girth weld as a starting point, and the number of the third girth welds is not particularly limited in the embodiment of the present application.
211. And the computer equipment matches any third pipeline information with the first pipeline information to obtain at least one second matching result.
In the embodiment of the application, the second matching result comprises whether the trend of the two side spiral weld seams of the first girth weld and the trend of the two side spiral weld seam of the third girth weld are consistent, and an error value between the distance value from the first girth weld to the two side spiral weld seam and the distance value from the third girth weld to the two side spiral weld seam. It should be noted that, the two cases of the second matching result are similar to the two cases of the first matching result given in the above step 207, so that a detailed description is omitted here.
212. And the computer equipment responds to any second matching result to meet a second target condition, and obtains the position information of the third girth weld and the target girth weld corresponding to the second matching result.
In the embodiment of the present application, the second matching result meeting the second target condition means that: the trend of the spiral weld at the two sides of the first girth weld is consistent with the trend of the spiral weld at the two sides of the third girth weld, and the error value between the distance value from the first girth weld to the spiral weld at the two sides and the distance value from the third girth weld to the spiral weld at the two sides meets the preset threshold.
The method comprises the following steps:
Step one: and the computer equipment responds to any second matching result to meet a second target condition, and obtains the girth weld number of the third girth weld corresponding to the second matching result.
And when any second matching result meets a second target condition, the computer equipment determines a third girth weld corresponding to the second matching result based on the second matching result, and acquires the girth weld number of the third girth weld. At this time, the third girth weld is actually the first girth weld actually excavated. In addition, the specific description of the second matching result meeting the second target condition is similar to the specific description of the "the first matching result meeting the first target condition" given in the above step 208, and thus will not be repeated here.
Step two: the computer equipment obtains the position information of the third girth weld and the target girth weld based on the girth weld number of the third girth weld and the girth weld number of the target girth weld.
In this step, the positional information is used to indicate the positional relationship between the third girth weld and the target girth weld. For example, the third girth weld is a first girth weld positioned to the left of the target girth weld, and for example, the third girth weld is a second girth weld positioned to the left of the target girth weld, and for example, the third girth weld is a girth weld positioned 50cm to the left of the target girth weld, and so on. The embodiment of the present application is not particularly limited in terms of the form of the position information.
Optionally, in the scenario that the girth weld numbers of the girth welds in the pipeline are continuously arranged according to the position sequence of the girth welds, the computer device can directly obtain the position information of the third girth weld and the target girth weld based on the girth weld numbers of the third girth weld and the girth weld numbers of the target girth weld. For example, referring to fig. 5, a third girth weld a09, a target girth weld a10, and a third girth weld a11 are shown from left to right, respectively. And if the second matching result corresponding to the third girth weld A09 meets the second target condition, the computer equipment determines that the third girth weld A09 is the first girth weld positioned on the left side of the target girth weld A10 based on the girth weld number A09 of the third girth weld and the girth weld number A10 of the target girth weld.
Optionally, the computer device queries the magnetic flux leakage inner detection data of the two girth welds in the magnetic flux leakage inner detection database by taking the acquired girth weld number of the third girth weld and the acquired girth weld number of the target girth weld as indexes to obtain magnetic flux leakage inner detection signal pages of the two girth welds, and determines the position information between the two girth welds from the magnetic flux leakage inner detection signal diagram displayed on the magnetic flux leakage inner detection signal page.
The method for acquiring the position information of the third girth weld and the target girth weld is not particularly limited in the embodiment of the application.
213. The computer device determines a location of the target girth weld based on the location information.
In the embodiment of the present application, through the steps 210 to 212, the computer device may find a third girth weld matched with the first girth weld actually excavated from the detected data in the magnetic flux leakage of the at least one third girth weld, and obtain the position information of the third girth weld and the target girth weld, in fact, obtain the position information of the first girth weld and the target girth weld, and then the computer device may re-determine the position of the target girth weld with reference to the position information.
For ease of understanding, this step is specifically illustrated below in conjunction with fig. 5:
In the case that the computer equipment determines that the third girth weld a09 is the first girth weld, the obtained position information of the third girth weld and the target girth weld is "the third girth weld a09 is the first girth weld located on the left side of the target girth weld a 10", and since the third girth weld is actually the first girth weld actually excavated, the computer equipment can determine the position information of the target girth weld by taking the position information as a reference, and the position information is "the first girth weld located on the right side of the first girth weld actually excavated".
Through the steps 210 to 213, after the computer device determines that the first girth weld is not the target girth weld under the condition that only the top of the pipeline is excavated, the computer device accurately locates the position of the target girth weld by matching the pipeline information of the first girth weld with the pipeline information of the existing girth weld, without determining the position of the target girth weld by ground measurement again, thereby saving the excavation amount and the corresponding workload of earthwork, improving the efficiency of excavating the girth weld, and avoiding unnecessary economic loss.
In addition, after determining the position of the target girth weld through the above steps 210 to 213, the above steps 201 to 213 are repeated for the newly excavated girth weld until the target girth weld is correctly excavated.
In the embodiment of the application, a method for determining a girth weld is provided, wherein in the process of excavating the girth weld, pipeline information of the two girth welds can be respectively obtained for the girth weld which is actually excavated and the girth weld which is required to be excavated, and then the pipeline information of the two girth welds is matched to determine whether the girth weld which is actually excavated is the girth weld which is required to be excavated. In the process of excavating the girth weld, whether the girth weld actually excavated is the girth weld to be excavated is judged in time, so that the accuracy of excavating the girth weld is improved, and unnecessary economic loss is avoided.
