Detailed Description
The application provides a method and a system for rechecking an optical fiber vibration alarm signal of an oil and gas pipeline, which are used for solving the technical problems of low effective rate and low accuracy of the optical fiber vibration alarm of the oil and gas pipeline in the prior art.
Summary of the application
In response to the development demands of industry, oil and gas pipeline construction is in an coming peak period, more and more long-distance pipelines enter areas with developed economy and dense population, and the activities such as third party construction in the areas are frequent, so that the risk of pipeline leakage caused by the third party construction is also increased. There are data showing that damage by third parties results in up to 40% of pipeline accidents. Therefore, the construction activities of the third party around the pipeline are required to be monitored, early warning is timely carried out, abnormal conditions are timely processed, and the pipeline is prevented from being damaged. However, the conventional manual line inspection cannot achieve 24-hour uninterrupted coverage, and real-time monitoring of the peripheral condition of the pipeline is required by technical protection measures. The optical fiber vibration monitoring technology utilizes the communication optical cable laid along the same ditch as the pipeline as a sensor, can monitor the soil vibration condition along the pipeline in real time in a long distance, alarms when construction vibration occurs near the pipeline through accurate vibration signal analysis, and accurately positions a target for a damage event of a third party, thereby reducing the damage risk of the third party of the pipeline.
On the one hand, the optical fiber vibration monitoring technology has higher sensitivity, and is easy to cause false alarm to the system due to harmless vibration, noise and other interference sources in the environment. For a long time, the low alarm effective rate is a main factor for restricting the large-scale application of the optical fiber vibration technology in the pipeline industry. Therefore, how to improve the effective alarm efficiency, the effective alarm events are distinguished among a plurality of alarm signals, and the effectiveness of the optical fiber vibration monitoring technology applied to the oil gas long-distance pipeline is determined.
On the other hand, at present, the optical fiber vibration alarm is usually checked on site manually, the informatization degree is low, under the condition of more false alarms, a great deal of manpower is required for manual check, the timeliness of alarm signal issuing and checking information returning is poor, whether third party construction occurs on site can not be judged rapidly, and the check workload of the optical fiber vibration alarm signal of the pipeline in the prior art is large and the efficiency is low.
In conclusion, the optical fiber vibration detection technology in the prior art has higher sensitivity, is easy to cause harmless vibration nearby a pipeline to give out an alarm, causes false alarm to a system, and has lower rechecking efficiency for optical fiber vibration signals. Therefore, the technical problems of low effective rate and low accuracy of the optical fiber vibration alarm of the oil and gas pipeline exist.
Aiming at the technical problems, the technical scheme provided by the application has the following overall thought:
According to the technical scheme, the pipeline path area is split according to the paving path information of the oil and gas pipeline, different pipeline areas are set to be different optical fiber vibration alarm sensitivities, the pipeline segmented collection is obtained, optical fiber vibration early warning is carried out based on the pipeline segmented area, when the optical fiber vibration alarm signal is obtained, whether the optical fiber vibration alarm signal is an operation plan vibration signal or not is judged, if not, the optical fiber vibration alarm signal is required to be rechecked according to a first rechecking mode or a second rechecking mode according to different conditions, whether the optical fiber vibration alarm signal is accurate or not is judged, after rechecking is finished, the optical fiber vibration alarm signal is marked according to rechecking information, marking results and the like are stored, and a data basis is provided for optimization of a subsequent method.
Having introduced the basic principles of the present application, the technical solutions of the present application will now be clearly and fully described with reference to the accompanying drawings, it being apparent that the embodiments described are only some, but not all, embodiments of the present application, and it is to be understood that the present application is not limited to the exemplary embodiments described herein. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application. It should be further noted that, for convenience of description, only some, but not all of the drawings related to the present application are shown.
Example 1
As shown in fig. 1, the application provides a method for rechecking an optical fiber vibration alarm signal of an oil and gas pipeline, which comprises the following steps:
S100: obtaining first pipe laying information;
In particular, the first pipe laying information is information of a path region of the long oil and gas pipeline in the laying process, and the laying can be any laying mode of the oil and gas pipeline in the prior art, and the laying and burying are exemplary, and linear laying is preferred.
From the first pipe-laying information described above, route area information at the time of first pipe-laying can be obtained, including, for example, areas of farmland, city, road, and the like. In the prior art, in the process of laying an oil and gas pipeline, a communication optical cable is laid in the same ditch of the pipeline, and vibration monitoring and early warning are carried out through optical fibers in the optical cable based on the Rayleigh scattering principle.
The first pipeline laying information can be obtained through drawings and other operation plan information in the oil and gas long-distance pipeline laying process, a map of pipeline distribution is formed, the oil and gas pipeline optical fiber vibration early warning is carried out based on the first pipeline laying information, and the alarm place and time can be determined through the optical fiber vibration alarm technology when an alarm occurs.
S200: splitting the first pipeline laying information according to a preset splitting rule to obtain a first pipeline segment set, and monitoring an optical fiber vibration alarm signal based on the first pipeline segment set;
in particular, in the first pipe-laying information, the oil and gas pipe passes through a plurality of different types of areas, and in the different areas, the possibility of false alarm of optical fiber vibration alarm generation is different, and in the different areas, the possibility of occurrence of damage to the pipe by third party construction is different.
Illustratively, in urban areas, such as economic development areas or densely populated areas, there are a large number of third party constructions, with a high likelihood of damaging the pipeline. In the river region, the noise vibration of the river is easy to trigger the vibration alarm of the optical fiber, so that false alarm is caused. Therefore, the first pipe-laying information needs to be split by different areas.
The step S200 in the method provided by the application comprises the following steps:
S210: obtaining first pipe laying path information based on the first pipe laying information;
S220: splitting the first pipeline laying path information according to the preset splitting rule to obtain a plurality of laying path sections;
S230: and setting different optical fiber vibration alarm sensitivities for a plurality of laying path sections to obtain the first pipeline segment set, wherein the different optical fiber vibration alarm sensitivities comprise high sensitivity, medium sensitivity and low sensitivity.
The preset splitting rule comprises splitting according to the frequency of third party construction in a pipeline path area and the frequency of optical fiber vibration false alarm, and a plurality of laying path sections are obtained.
Then, as the probability of optical fiber vibration false alarm and the probability of pipeline damage are different in the plurality of laying path sections, different optical fiber vibration alarm sensitivities are set for the plurality of laying path sections according to the probability of optical fiber vibration false alarm and the probability of pipeline damage, and a first pipeline segment set is obtained. Wherein, different optical fiber vibration alarm sensitivities include high sensitivity, medium sensitivity and low sensitivity.
Specifically, for a laying path section with higher probability of occurrence of optical fiber vibration false alarm, the optical fiber vibration alarm sensitivity is set to be low, so that the occurrence probability of the optical fiber vibration false alarm is reduced, and the rechecking cost is reduced. And setting the fiber vibration alarm sensitivity to be high for a laying path section with higher probability of pipeline damage, and timely early warning vibration nearby the pipeline and rechecking to avoid pipeline damage. And for other areas, the sensitivity can be set to be medium, and the normal optical fiber vibration early warning can be carried out.
Illustratively, the plurality of layup path segments described above comprises: third party construction points in plan, road crossing pipe sections, economic development areas, densely populated areas, crossing river pipe sections, farmland pipe sections, and other pipe sections.
When the construction is performed near the pipeline, a third party construction unit reports a construction plan (construction site, time, construction scheme and the like) to the oil and gas pipeline unit to form a planned third party construction point, and in the construction process, a pipeline management unit can arrange a special person to perform whole-course on-site monitoring, so that monitoring is performed by a guardian on site in the construction time, and in order to reduce review workload, the optical fiber vibration alarm sensitivity of the planned third party construction point is set to be low in the time period. If an optical fiber vibration alarm occurs outside the construction time, it is explained that the construction unit is illegally constructed, and therefore, the optical fiber vibration alarm sensitivity is set to be high outside the planned construction time period.
The road crossing pipe section is frequent in vehicle passing, noise can be produced when the vehicle passes, so that the optical fiber vibration monitoring system alarms, and false alarms are caused, and therefore, the road crossing pipe section and the optical fiber vibration monitoring system alarm sensitivity is set to be low.
Construction and excavation activities in the economic development area are frequent, and the construction activities of a third party are high in sporadic performance and cannot be used for reporting and backup management, and the risk of pipeline accidents caused by the construction of the third party is maximum, so that the monitoring sensitivity of optical fiber vibration in the economic development area is set to be high.
Excavation activities are frequent in densely populated areas, and the optical fiber vibration monitoring sensitivity is set to be high.
When the pipeline passes through a river, the optical fiber vibration monitoring system alarms due to noise generated by water flow, so that the alarm sensitivity of the optical fiber vibration monitoring system of the river-passing pipe section is set to be low.
When the pipe section passes through the farmland, a large-scale farming tool is often adopted during farming, the pipeline is extremely threatened, and therefore the alarm sensitivity is set to be high.
And (3) carrying out normalized optical fiber vibration early warning on other pipe sections, wherein the warning sensitivity is set to be medium sensitivity.
The above description of multiple laying path sections is only a specific embodiment of the present application, so as to better understand the technical solution of the present application, and is not meant to limit the present application.
The optical fiber vibration alarm sensitivity is set to comprise high sensitivity, medium sensitivity and low sensitivity, and the optical fiber vibration alarm triggering threshold can be adjusted based on the Rayleigh scattering principle so as to realize the setting of the optical fiber vibration alarm sensitivity.
According to the method provided by the application, the first pipeline laying information is split according to the probability of false alarm and the probability of pipeline damage, and different alarm sensitivity alarms are set, so that the probability of false alarm occurrence can be effectively reduced, the rechecking cost is reduced, the construction behavior of the damaged pipeline can be effectively pre-warned, the targeted pre-warning is realized, and the technical effects of improving the accuracy and the effectiveness of the optical fiber vibration alarm are achieved.
S300: obtaining a first optical fiber vibration alarm signal;
s400: judging whether the first optical fiber vibration alarm signal is an operation plan vibration signal or not;
S500: checking the first optical fiber vibration alarm signal if the first optical fiber vibration alarm signal is not the operation plan vibration signal, and ignoring the first optical fiber vibration alarm signal if the first optical fiber vibration alarm signal is the operation plan vibration signal;
Specifically, the first optical fiber vibration alarm signal is an alarm signal triggered when the optical cable near the oil and gas pipeline detects vibration information. The third party construction unit reports the construction to the pipeline management system before the construction, the pipeline management system takes the construction as the planned construction, and excludes the pipeline supervisor to conduct on-site operation supervision, the operation planned vibration signal is an optical fiber vibration alarm signal which is sent out in the planned operation area in the planned operation time under the condition that the pipeline supervisor monitors on site, and the optical fiber vibration alarm signal is used for the planned construction and is supervised by personnel, so that the pipeline is not damaged, and the processing is not needed.
The first optical fiber vibration alarm signal may be an operation plan vibration signal, or may be a false alarm signal sent by river vibration noise or automobile vibration noise, so that in order to further reduce the cost of checking the optical fiber vibration alarm signal, it is necessary to determine whether the first optical fiber vibration alarm signal is an operation plan vibration signal, and screen the optical fiber vibration signal.
As shown in fig. 2, step S400 in the method provided by the present application includes:
S410: obtaining job planning information, wherein the job planning information comprises a planned job position information set and a planned job time information set;
s420: acquiring alarm position information and alarm time information according to the first optical fiber vibration alarm signal;
s430: judging whether the alarm position information belongs to the planned position information set or not;
s440: if the alarm position information does not belong to the planned position information set, judging that the first optical fiber vibration alarm signal is not the operation planned vibration signal;
S450: if the alarm position information belongs to the planned position information set, judging whether the alarm time information belongs to the planned operation time information set, if so, judging whether supervision exists at the alarm position information, and if not, judging that the first optical fiber vibration alarm signal is not the operation plan vibration signal;
S460: and if no supervision exists at the alarm position information, the first optical fiber vibration alarm signal is not the operation plan vibration signal.
Specifically, the operation plan information of all the operation plans is obtained from the operation plan information reported by the third party construction operation unit in the pipeline management system. The job planning information includes a job position information set and a planned job time information set. Wherein the job location information set includes job location areas of all job plans, and the planned job time information set includes planned job time periods of all job plans.
And then, according to the first optical fiber vibration alarm signal, alarm position information and alarm time information of the optical fiber vibration alarm signal are obtained based on an optical fiber vibration alarm technology.
Further, whether the alarm position information belongs to a planned position information set or not is judged, namely whether the alarm position information belongs to a region in the planned construction which is already reported or not, and if not, the first optical fiber vibration alarm signal is not an operation planned vibration signal. And if so, acquiring the scheduled operation time information of the operation plan corresponding to the alarm position information, wherein the scheduled operation time information belongs to the scheduled operation time information set, further judging whether the alarm time information belongs to the scheduled operation time information, and if not, judging that the first optical fiber vibration alarm signal is not an operation plan vibration signal.
If the alarm time information belongs to the planned operation time information, further judging whether a pipeline supervisor monitors the alarm position information.
The method provided by the application in step S450 judges whether supervision exists at the alarm position information or not, and comprises the following steps:
S451: acquiring a working field information set at the alarm position information;
s452: judging whether a supervisor monitors the operation site information set;
s453: if the monitoring personnel exist in the operation site information set, monitoring exists at the alarm information position;
s454: if no supervisor exists in the operation site information set, no supervision exists at the alarm information position.
Specifically, the alarm position information is a certain area of the first optical fiber vibration alarm signal corresponding to the alarm position, if the alarm position information is subjected to planning operation in the planning position and the planning time, pipeline supervision staff can supervise the pipeline on site, construction damage is avoided, and if the supervision staff does not supervise the pipeline to perform construction, the possibility of damage to the pipeline exists.
Specifically, a working field information set at the alarm position information is acquired, wherein the working field information set comprises field image data acquired according to a camera of a working field and supervisor dispatch information acquired through a pipeline line inspection system. According to the operation site information set, whether the construction at the alarm position information is supervised by a supervisor or not can be judged.
If the monitoring personnel exist in the operation site information set, monitoring exists at the alarm information position, and if the monitoring personnel do not exist in the operation site information set, monitoring does not exist at the alarm information position.
If supervision exists at the alarm position information, the first optical fiber vibration alarm signal is an operation plan vibration signal, the operation construction in plan is carried out at the alarm position information, supervision personnel supervision exists, the risk of damaging a pipeline is avoided, the risk is low, processing is not needed, and the first optical fiber vibration alarm signal is ignored.
If no supervision exists at the alarm position information, the planned operation is performed at the alarm position information, but no supervision personnel performs supervision, and the risk of damaging the pipeline is high, so that the first optical fiber vibration alarm signal is not an operation plan vibration signal, and a recheck is needed, and whether the first optical fiber vibration alarm signal is real or not is ensured, and the on-site processing is performed, so that the pipeline is prevented from being damaged.
According to the method provided by the application, the first optical fiber vibration alarm signal is screened to judge whether the first optical fiber vibration alarm signal is an operation plan vibration signal, if the first optical fiber vibration alarm signal is the operation plan vibration signal, the pipeline is considered not to be damaged, the rechecking treatment is not carried out, and if the first optical fiber vibration alarm signal is not the operation plan vibration signal, the rechecking calculation cost can be reduced, and the accuracy and the effectiveness of the optical fiber vibration alarm can be improved.
S600: rechecking the first optical fiber vibration alarm signal based on a first rechecking mode or a second rechecking mode to obtain first rechecking information;
The first optical fiber vibration alarm signal, which is not an operation planning vibration signal, may be a false alarm signal or may be alarm information caused by construction that may damage a pipe, and thus, it is necessary to review the first optical fiber vibration alarm signal.
As shown in fig. 3, step S600 in the method provided by the present application includes:
S610: acquiring the alarm position information;
s620: judging whether an image acquisition device exists in a preset range of a position corresponding to the alarm position information;
s630: if the image acquisition device exists, rechecking the first optical fiber vibration alarm signal in a first rechecking mode;
S640: and if the image acquisition device does not exist, rechecking the first optical fiber vibration alarm signal according to a second rechecking mode.
Specifically, as described above, the warning position information including the pile number and the offset corresponding to the pipe is obtained from the first optical fiber vibration warning signal and the first pipe laying information.
