Description

Technical Field

[0001] The present invention relates to the technical field of pipeline pressure control, and in particular to a pipeline network pressure control method based on data analysis. Background Art

[0002] The pipe network system is a pipeline system for transporting and distributing water to users in water supply projects, also known as the water supply network. The pipe network system is an important urban facility that undertakes the important function of supplying water to residential users. The daily changes in residents' water consumption lead to changes in the internal pressure of the pipe network system, which causes leakage in the pipe network system. The traditional pipe network pressure control method is to manually monitor the pipeline pressure instrument and manually adjust the water valve to control the pipeline pressure to reduce the risk of pipeline leakage. However, this method is quite labor-intensive and inefficient.

[0003] Chinese Patent Publication No.: CN112987811A discloses a pipe network pressure control system, method, pipe network system and storage medium. The method obtains the pipe pressure data detected by the pressure sensor as the first pressure data; determines whether the first pressure data is greater than or equal to the first threshold value, and when the first pressure data is greater than or equal to the first threshold value, controls the water valve to reduce the opening; after the opening of the water valve is reduced, obtains the pipe pressure data detected by the pressure sensor as the second pressure data; determines whether the second pressure data is less than the first threshold value, and when the second pressure data is less than the first threshold value, determines whether the second pressure data is greater than the second threshold value, and the second threshold value is less than the first threshold value; when the second pressure data is greater than the second threshold value, controls the water valve to maintain the opening corresponding to the second pressure data. The invention can automatically detect the pressure of the water supply pipe, thereby automatically controlling the opening of the water valve, reducing the risk of pipe leakage, consuming less manpower, and having a high degree of automation.

[0004] It can be seen that the existing technology has the problem of low accuracy and flexibility in controlling the pipeline pressure, which may lead to pipeline bursting and affect the normal operation of the pipeline system. Summary of the invention

[0005] To this end, the present invention provides a pipeline pressure control method based on data analysis to overcome the problem in the prior art of low accuracy and flexibility in pipeline pressure control, which may lead to pipeline bursting and affect the normal operation of the pipeline system.

[0006] To achieve the above object, the present invention provides a pipe network pressure control method based on data analysis, comprising:

[0007] Step S1, the data acquisition module acquires the values ​​of the pressure sensor arranged behind the main pipeline regulating valve for detecting the main pipeline pressure and the pressure sensor arranged behind the regulating valve at the junction of the main pipeline and the branch pipeline for detecting the branch pipeline pressure;

[0008] Step S2: The data analysis module compares and analyzes the value of the pressure sensor with the preset pressure to determine the safety of the pipeline;

[0009] Step S3, the control module determines the control mode of the regulating valve arranged on the main pipeline for regulating the flow rate of the medium inside the pipeline and the regulating valve arranged at the junction of the main pipeline and the branch pipeline for regulating the flow rate of the medium inside the branch pipeline according to the analysis result of the data analysis module;

[0010] Step S4, the adjustment module determines the fault evaluation value of the pipeline network according to the pressure values ​​of each branch of the pipeline network and the preset pressure, and then determines whether to adjust the pipeline pressure;

[0011] Step S5: The optimization module determines whether to optimize the pipe network pressure control process according to the usage time and usage frequency of each pipe in the pipe network.

[0012] Furthermore, the data analysis module determines the safety of the pipeline working condition based on the comparison result of the value of the pressure sensor and the preset pressure. When the value is less than the preset pressure, the data analysis module determines that the pipeline working condition is safe, or when the value is greater than or equal to the preset pressure, the data analysis module determines that the pipeline working condition is unsafe.

[0013] Further, when the data analysis module determines that the working condition of the pipeline is unsafe, the control module determines to control the regulating valve in a first control mode, wherein the first control mode includes reducing the valve opening by a first coefficient until the value of the pressure sensor is less than a preset pressure, or when the working condition of the pipeline is safe, the control module performs a secondary judgment.

[0014] Further, under the condition that the control module determines to perform a secondary judgment, the control module determines the control mode of the regulating valve according to the comparison result of the absolute value of the difference between the numerical value of the pressure sensor and the preset pressure and the first preset difference, and under the condition that the absolute value of the difference is less than the first preset difference, the control module determines to control the regulating valve in a second control mode, and the second control mode includes increasing the valve opening by a second coefficient until the absolute value of the difference is less than the preset difference.

[0015] Further, under the condition of determining to perform a secondary judgment, the control module determines the control mode of the regulating valve according to the comparison result of the absolute value of the difference between the numerical value of the pressure sensor and the preset pressure and the first preset difference, and under the condition that the absolute value of the difference is greater than or equal to the first preset difference, the control module determines to control the regulating valve in a third control mode, and the third control mode includes maintaining the valve opening unchanged.

[0016] Furthermore, the adjustment module determines to adjust the pipeline network pressure control process according to the comparison result of the fault evaluation value of the pipeline network and the preset fault evaluation value, and under the condition that the fault evaluation value is less than the preset fault evaluation value, the adjustment module determines to adjust the pipeline network pressure control process.

[0017] Further, the adjustment module determines an adjustment method based on a comparison result of an absolute value of a difference between a fault evaluation value and a preset fault evaluation value and a second preset difference, and under the condition that the absolute value of the difference is less than or equal to the second preset difference, the adjustment module performs adjustment in a first adjustment method, wherein the first adjustment method includes adjusting the preset pressure with an adjustment coefficient, or under the condition that the absolute value of the difference is greater than the second preset difference, the adjustment module performs adjustment in a second adjustment method, wherein the second adjustment method includes sending a pipeline maintenance warning signal to the terminal.

[0018] Furthermore, the optimization module determines to optimize the pipeline network pressure process based on the comparison result of the pipeline network life evaluation value and the preset pipeline network life evaluation value, and under the condition that the pipeline network life evaluation value is less than the preset pipeline network life evaluation value, the optimization module determines to optimize the pipeline network pressure control process.

[0019] Furthermore, the optimization module determines an optimization method based on a comparison result of the absolute value of the difference between the pipeline life evaluation value and the preset pipeline life evaluation value with a third preset difference, and under the condition that the absolute value of the difference is greater than or equal to the third preset difference, the optimization module determines to optimize in a first optimization method, and the first optimization method includes optimizing the preset fault evaluation value with a first optimization coefficient.

[0020] Furthermore, the optimization module determines the optimization method based on the comparison result of the absolute value of the difference between the pipeline life evaluation value and the preset pipeline life evaluation value and the third preset difference, and under the condition that the absolute value of the difference is less than the third preset difference, the optimization module determines to optimize in a second optimization method, and the second optimization method includes optimizing the preset fault evaluation value with a second optimization coefficient.

[0021] Compared with the prior art, the beneficial effect of the present invention lies in that the present invention determines whether the pipeline can withstand the medium pressure according to the comparison result of the value of the pressure sensor and the preset pressure through the data analysis module, and dynamically monitors the pressure in the pipeline and the maximum working pressure of the pipeline by using the pressure sensor and then dynamically adjusts the regulating valve to control the pressure in the pipeline, thereby improving the accuracy and flexibility of the pipeline network pressure control, thereby avoiding the phenomenon of pipeline bursting due to excessive internal pressure.

[0022] Furthermore, the present invention determines the control mode of the regulating valve according to the analysis result of the data analysis module through the control module to dynamically adjust the pressure in the pipeline to avoid the pipeline bursting due to excessive pressure in the pipeline, thereby improving the accuracy and flexibility of the pipeline in controlling its internal pressure when working. At the same time, the control module makes a secondary judgment on the safety of the pipeline work, and adjusts the pipeline with low internal pressure to improve the work efficiency, thereby achieving the dual guarantee of high safety and high efficiency when the pipeline is working.

[0023] Furthermore, the present invention determines the control method of the valve opening according to the pressure of the medium flowing out under the initial valve opening on the pipeline through the control module. When the pressure in the pipeline is greater than or equal to the preset pressure, the control module determines that the valve opening of the regulating valve is large at this time, and then reduces the valve opening; when the pressure in the pipeline is much lower than the preset pressure, the control module determines that the valve opening of the regulating valve is small at this time, and then increases the valve opening; the above method realizes flexible control of the pressure in the pipeline and thus improves the accuracy of the pressure control of the pipeline network.

[0024] Furthermore, the present invention calculates a fault evaluation value according to the pressure data of each branch pipeline of the pipeline network through an adjustment module, and compares the fault evaluation value with a preset fault evaluation value to determine whether to adjust the pipeline network pressure control process. When the fault evaluation value is greater than the preset fault evaluation value, the adjustment module determines that the quality of each branch pipeline of the pipeline network is low, and the adjustment module determines to adjust the pressure control process of the pipeline. The above method improves the accuracy of pipeline network pressure control and avoids the occurrence of pipeline bursting due to excessive internal pressure.

[0025] Furthermore, the present invention determines an adjustment method through an adjustment module according to a comparison result of an absolute value of a difference between a fault evaluation value and a preset fault evaluation value and a second preset difference. When the absolute value of the difference is less than or equal to the second preset difference, the adjustment module determines that the probability of failure in the pipeline network is small, and the adjustment unit determines to adjust the preset pressure with an adjustment coefficient to reduce the bearing pressure of the pipeline network and thereby avoid the occurrence of pipeline network failure. When the absolute value of the difference is greater than the second preset difference, the adjustment unit determines that a failure has occurred in the pipeline network, and the adjustment unit determines to send a pipeline maintenance warning signal. The above method improves the accuracy of pipeline network pressure control and thereby improves the safety of the pipeline network during operation.

[0026] Furthermore, the present invention calculates a service life evaluation value of the pipeline network according to the usage time and number of times the pipeline network is used through an optimization module to determine whether the optimization module optimizes the pipeline network pressure control process. When the service life evaluation value of the pipeline network is greater than or equal to a preset pipeline network service life evaluation value, the adjustment module determines that the pipeline network has been in use for a long time and there is wear and tear, which leads to a decrease in the maximum working pressure of the pipeline. The safety of the pipeline network at work is improved by optimizing the pipeline network pressure control process. In addition, the optimization module determines the optimization method based on the comparison result of the absolute value of the difference between the pipeline network life evaluation value and the preset pipeline network life evaluation value with a third preset difference. The above method further improves the accuracy and flexibility of the pipeline network pressure control process, thereby ensuring the safety of the pipeline network at work.

[0046] Wherein, i=1, 2, ..., N; N represents the total number of main pipelines and branch pipelines, and the value of the preset pressure Fi0 is nine-tenths of the maximum working pressure of the pipeline where the pressure sensor is located, but the above value is not limited to this, and technicians in this field can also adjust the value according to actual needs.

[0047] The value of the pressure sensor in the embodiment of the present invention includes the value of the pressure sensor of the main pipeline and the value of the pressure sensor of the branch pipeline.

[0048] Specifically, the present invention determines whether the pipeline can withstand the medium pressure according to the comparison result of the value of the pressure sensor and the preset pressure through the data analysis module, and dynamically adjusts the regulating valve to control the pressure in the pipeline by dynamically monitoring the pressure in the pipeline and the maximum working pressure of the pipeline using the pressure sensor, thereby improving the accuracy and flexibility of the pipeline network pressure control, thereby avoiding the phenomenon of pipeline bursting due to excessive internal pressure.

[0050] When the data analysis module determines that the pipeline is in safe working condition, the control module determines to perform a secondary determination.

[0051] Specifically, when the control module performs secondary determination, the control module determines the control mode of the regulating valve according to the comparison result of the absolute value of the difference △F between the value of the pressure sensor and the preset pressure and the first preset difference △F0;

When the absolute value of the difference is less than or equal to the second preset difference, the adjustment module determines that the probability of failure of the pipeline network is small, and the adjustment unit determines to adjust the preset pressure with the adjustment coefficient to reduce the bearing pressure of the pipeline network and thus avoid the occurrence of pipeline network failure. When the absolute value of the difference is greater than the second preset difference, the adjustment unit determines that a failure has occurred in the pipeline network, and the adjustment unit determines to send a pipeline maintenance warning signal.

When the service life evaluation value of the pipeline network is greater than or equal to the preset pipeline network service life evaluation value, the adjustment module determines that the pipeline network has been in use for a long time and there is wear and tear, which leads to a decrease in the maximum working pressure of the pipeline. The safety of the pipeline network at work is improved by optimizing the pipeline network pressure control process. In addition, the optimization module determines the optimization method based on the comparison result of the absolute value of the difference between the pipeline network life evaluation value and the preset pipeline network life evaluation value with the third preset difference. The above method further improves the accuracy and flexibility of the pipeline network pressure control process, thereby ensuring the safety of the pipeline network at work.
