A method for remote monitoring of pipeline failure, as shown in fig. 1, comprising:
s101, dividing pipelines in an industrial plant into a high maintenance probability fault area and a low maintenance probability fault area according to historical maintenance data;
s102, in the high maintenance probability fault area, acquiring a pipeline thickness parameter, a pipeline pressure parameter, a pipeline temperature parameter and a pipeline flow parameter when a pipeline runs;

Therefore, in the invention, the pipeline can be automatically detected through the pressure instrument, the temperature instrument, the flow instrument and the thickness measuring device, the specific reason and the fault type of the pipeline can be rapidly predicted if the pipeline has a fault, maintenance personnel do not need to go to the field for detection, the fault pipeline is timely processed, the maintenance time is shortened, and the maintenance efficiency is improved.
Optionally, in the present invention, the step S102 further includes sequentially numbering the positions of the pipes in the high repair probability fault area;
the early warning information comprises the leakage type or the blockage type and a corresponding pipeline number.
Wherein one pipe corresponds to one pipe number.
Therefore, when a certain pipeline in an industrial plant (such as but not limited to a nuclear power station) breaks down, maintenance personnel can timely determine the position of the pipeline through the serial number of the pipeline, timely maintenance and replacement of the pipeline are facilitated, the maintenance time is shortened, and the maintenance efficiency is improved.
Optionally, in the present invention, before the step S101, the method further includes:
and calculating the standard thickness parameter of each pipeline, the standard pressure parameter borne by the pipeline under the normal working condition and the standard flow parameter under the normal working condition of the pipeline, and storing the standard thickness parameter, the standard pressure parameter and the standard flow parameter into a database.
For example, a standard thickness parameter for a pipe may be, but is not limited to, 150 mm;
the standard pressure parameter for a pipeline may be, but is not limited to, 6.71 Mpa;
the standard flow parameter for the pipeline may be, but is not limited to, 1615 kg/s.
Optionally, in the present invention, the S101 includes:
judging whether the pipeline is maintained or not;
if yes, the pipeline is divided into the high maintenance probability fault areas;
if not, the pipeline is divided into the low maintenance probability fault areas.
It should be noted that, because the overall floor space of an industrial plant (for example, but not limited to, a nuclear power plant) is large, a pipeline can be divided into two areas, namely, a high maintenance probability fault area and a low maintenance probability fault area according to historical maintenance data.
And the inspection and maintenance period of the high maintenance probability fault area is shorter than that of the low maintenance probability fault area.
For example, for a fault area with high repair probability, every month, each pipeline in the area needs to be detected;
for a fault area with low maintenance probability, every three months, each pipeline in the area can be detected.
And, after the pipe in the low maintenance probability failure region is failed and maintained, the pipe is automatically classified into the high maintenance probability failure region.
Optionally, in the present invention, the S102 includes:
the pipeline is provided with a moving ring sleeved on the outer side of the pipe wall and a driving device for driving the moving ring to move along the axis of the pipeline, the moving ring is provided with a thickness measuring device, the moving ring drives the thickness measuring device to move along the length direction of the pipeline, and the thickness of each position of the pipeline is detected to obtain a pipeline thickness parameter;
the pressure instrument is arranged on the pipeline and is used for detecting the pressure in the pipeline so as to obtain the pipeline pressure parameter;
the temperature instrument is arranged on the pipeline and is used for detecting the temperature in the pipeline so as to obtain the temperature parameter of the pipeline;
the flow meter is arranged on the pipeline and detects the flow in the pipeline to obtain the pipeline flow parameter.
Explaining one point, the thickness measuring device can comprise a plurality of thickness measuring instruments which are all arranged on the moving ring, therefore, when the driving device drives the moving ring to move along the axis of the pipeline, the thickness measuring instruments on the moving ring can detect the thickness of each position on the pipeline, and the thickness parameter of the pipeline is determined.
Therefore, the thickness measuring device, the pressure instrument, the temperature instrument and the flow instrument are arranged, so that the pipeline thickness parameter, the pipeline pressure parameter, the pipeline temperature parameter and the pipeline flow parameter of the pipeline during operation can be measured, and the subsequent prediction of the leakage type and the blockage type of the pipeline is facilitated according to the parameters.
Optionally, in the present invention, the S103 includes;
and when the absolute value of the difference value between the pipeline thickness parameter measured at a certain position of the pipeline and the standard thickness parameter is greater than a first preset thickness value, and the pipeline pressure parameter is greater than the standard pressure parameter within a first preset time, predicting that the pipeline leakage type is the hole leakage.
So, when the hole was revealed takes place for the pipeline, maintenance personal can repair the pipeline, can make the pipeline reconversion, consequently, has reduced the maintenance scope, avoids unnecessary dismantlement and change, reduces artifical detection intensity, if carry out whole change to the pipeline, not only the maintenance cycle length is long, has still increased the cost.
For example, 1:
take as an example a standard thickness parameter of 150mm, a first predetermined thickness value of 50mm, a first predetermined time of 2 seconds and a standard pressure parameter of 6.71 Mpa.
Because the thickness measuring device is used for detecting in real time, the measured pipe thickness parameters can exist in a plurality of numbers. Wherein, the thickness parameters of the pipeline detected by the thickness measuring device are 60mm and 145 mm;
the pipeline pressure parameter detected by the pressure instrument is 7 Mpa.
According to the data, the following data are obtained: the absolute value of the difference value between the pipeline thickness parameter 60mm and the standard thickness parameter 150mm is 90 which is larger than the first preset thickness value 50, and the pipeline pressure parameters are all larger than the standard pressure parameter 6.71Mpa within 2 seconds of the first preset time, so that the condition of hole leakage is met, and therefore, the type of leakage of the pipeline is predicted to be hole leakage;
the absolute value of the difference value between the pipeline thickness parameter 145mm and the standard thickness parameter 150mm is 5, the difference value is smaller than a first preset thickness value 50, in a first preset time of 2 seconds, the pipeline pressure parameters are all larger than the standard pressure parameter 6.71Mpa, the first condition of hole leakage is not met, therefore, the leakage type of the pipeline cannot be predicted, and early warning information is sent out and comprises the current pipeline pressure parameter, the pipeline thickness parameter and the pipeline number, so that maintenance personnel can be prompted to check and maintain.
Optionally, in the present invention, the S103 includes:
and when the absolute value of the difference value between the pipeline thickness parameter and the standard thickness parameter of at least three measurement positions on a certain section of the pipeline is greater than a first preset thickness value, and the pipeline pressure parameter is greater than the standard pressure parameter within a first preset time, predicting that the pipeline is broken if the leakage type of the pipeline is the pipeline breakage type.
So, when the pipeline takes place to break, that is to say, when the large tracts of land is damaged, maintenance personal need change this pipeline, avoids repairing the pipeline and causes the problem of waste time to make the pipeline in time resume normally.
For example, 2:
take for example a standard thickness parameter of 150mm, a first preset thickness value of 50mm, a first preset time of 2 seconds and a standard pressure parameter of 6.71 Mpa.
If the thickness measuring device detects that the pipeline thickness parameters of three measuring positions on a certain section of the pipeline are 65mm, 50mm and 45 mm;
the pipeline pressure parameter detected by the pressure instrument is 7.5 Mpa.
According to the data, the following data are obtained: the absolute value of the difference value between the pipeline thickness parameter 65mm and the standard thickness parameter 150mm is 85, and is greater than the first preset thickness value 50; the absolute value of the difference value between the pipeline thickness parameter 50mm and the standard thickness parameter 150mm is 100 and is greater than a first preset thickness value 50; the absolute value of the difference value between the pipeline thickness parameter 45mm and the standard thickness parameter 150mm is 105, and is greater than the first preset thickness value 50; in addition, when the pipeline pressure parameters are all greater than the standard pressure parameters within 2 seconds within the first preset time, the second condition of hole leakage is met, and therefore the pipeline is predicted to be in normal operation temporarily;
the absolute value of the difference between the pipeline thickness parameter 60mm and the standard thickness parameter 150mm is 90, which is greater than the first preset thickness value 50; within a second preset time of 5 seconds, the thickness parameters of the pipeline measured by the thickness measuring device are all 60mm and are smaller than a second preset thickness value of 80 mm; and the pipeline pressure parameter 7.5Mpa is greater than the standard pressure parameter 6.71 Mpa; the condition for the breakage of the pipe is satisfied, and therefore, the type of the leakage of the pipe is predicted to be the breakage of the pipe.
Optionally, in the present invention, the S104 includes:
and when the times that the pipeline temperature parameter is smaller than the preset temperature parameter, the pipeline pressure parameter is larger than the standard pressure parameter and the pipeline flow parameter is smaller than the standard flow parameter within a second preset time reach preset times, predicting that the blockage type of the pipeline is the freezing blockage.
Therefore, when the pipeline is frozen and blocked, the pipeline can be melted by an external heating mode, and therefore, the maintenance cost is greatly saved.
For example, 3:
take the preset temperature as minus 1 degree centigrade, the standard pressure parameter as 6.71Mpa, the standard flow parameter as 1615kg/s, the second preset time as 24h and the preset times as 5 times as examples.
Detecting a pipeline flow parameter of 1500kg/s by a flow meter;
detecting a pipeline temperature parameter at-15 ℃ by a temperature instrument;
the pipeline pressure parameter detected by the pressure instrument is 7.5 Mpa.
According to the data calculation, the following results are obtained: the temperature parameter of the pipeline is-15 ℃ lower than the preset temperature parameter of-1 ℃; the pipeline pressure parameter 7.5Mpa is greater than the standard pressure parameter 6.71 Mpa; and within a second preset time of 24h, the number of times that the pipeline flow parameter 1500kg/s is smaller than the standard flow parameter 1615kg/s reaches a preset number of times of 5; three conditions for frozen clogging are satisfied, and therefore, the type of clogging of the pipe is predicted to be frozen clogging.
Optionally, in the present invention, the S104 includes:
and when the times that the pipeline temperature parameter is greater than the preset temperature parameter, the pipeline pressure parameter is greater than the standard pressure parameter and the pipeline flow parameter is less than the standard flow parameter within a second preset time reach preset times, predicting that the blockage type of the pipeline is the impurity blockage.
So, when pipeline impurity blockked up, need dismantle the pipeline, impurity in the clearance pipeline.
For example, 4:
take the preset temperature as minus 1 degree centigrade, the standard pressure parameter as 6.71Mpa, the standard flow parameter as 1615kg/s, the second preset time as 24h and the preset times as 5 times as examples.
Detecting a pipeline flow parameter of 1500kg/s through a flow instrument;
detecting a pipeline temperature parameter of 15 ℃ by a temperature instrument;
the pipeline pressure parameter detected by the pressure instrument is 7.5 Mpa.
According to the data, the following data are obtained: the temperature parameter of the pipeline is 15 ℃ and is greater than the preset temperature parameter of minus 1 ℃; the pipeline pressure parameter 7.5Mpa is greater than the standard pressure parameter 6.71 Mpa; and within a second preset time of 24h, the number of times that the pipeline flow parameter 1500kg/s is smaller than the standard flow parameter 1615kg/s reaches a preset number of times of 5; three conditions for freezing blockage are all satisfied, and therefore, the blockage type of the pipeline is predicted to be impurity blockage.
Optionally, in the present invention, the management method is further configured with an overhaul policy, where the overhaul policy includes that the driving device drives the thickness measuring device to measure the thickness of the pipeline at a first time period, records and compares the pipeline thickness variation parameters of each pipeline in the high repair probability fault region in the first time period, and sends out an overhaul signal when the pipeline thickness variation parameter is greater than a first threshold. The overhaul signal comprises a first time period, a pipeline thickness variation parameter and a pipeline number.
Therefore, in the invention, the condition of the pipeline can be actively and periodically detected, so that the condition of missed detection caused by periodic detection is avoided, and when the thickness of the pipeline changes greatly, an overhaul signal is generated to prompt a maintainer to inspect and maintain the pipeline.
The working principle of the invention is as follows:
storing the standard thickness parameters of each pipeline, the standard pressure parameters born by the pipeline under the normal working condition and the standard flow parameters under the normal working condition of the pipeline; judging whether the pipeline is maintained or not; if yes, the pipeline is divided into high-maintenance-probability fault areas; if not, the pipeline is divided into low maintenance probability fault areas; in a high maintenance probability fault area, acquiring a pipeline thickness parameter, a pipeline pressure parameter, a pipeline temperature parameter and a pipeline flow parameter of a pipeline in operation, and specifically detecting through corresponding equipment, wherein repeated description is not provided; predicting the leakage type of the pipeline according to the pipeline thickness parameter and the pipeline pressure parameter, and predicting the blockage type of the pipeline according to the pipeline pressure parameter, the pipeline temperature parameter and the pipeline flow parameter, which is specifically referred to above, such as 1 to 4; when one of hole leakage, pipeline breakage, freezing blockage and impurity blockage of the pipeline is predicted, corresponding early warning information is sent out; and prompting maintenance personnel to maintain, specifically, adopting different solutions according to different fault types of the pipeline.
