[0001] The invention relates to the technical field of pipeline detection, in particular to an intelligent pressure detection system for valve pipelines. Background Art

[0002] Valve pipeline refers to components including valves and pipelines, which together constitute the channels for fluid transmission, distribution, control and regulation. The opening and closing and adjustment of valves can change the on-off and flow rate of the medium in the pipeline to meet the needs of process or equipment operation.

[0003] At present, when testing the pressure in the pipeline, it is impossible to accurately feedback the control status of all valves on the pipeline before conducting pressure abnormality analysis, and it is impossible to fully analyze and comprehensively evaluate the management risk level of the pipeline, which is not conducive to the reasonable subsequent plan of the pipeline, and it is difficult to effectively ensure the operation safety of the pipeline, and the degree of intelligence is low;

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent pressure inspection system for valve pipelines, which solves the problems that the prior art cannot accurately feedback the control status of all valves on the pipeline before performing pressure abnormality analysis, and cannot comprehensively analyze and comprehensively evaluate the management risk level of the pipeline, making it difficult to effectively ensure the operation safety of the pipeline and having a low degree of intelligence.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An intelligent pressure inspection system for valve pipelines, comprising a valve opening and closing detection module, a pipeline pressure inspection module, a pipeline risk comprehensive assessment module and a remote monitoring center;

[0008] The valve opening and closing detection module obtains all valves on the pipeline to be monitored, analyzes the opening and closing status of the corresponding valves, identifies the valves that are opened and closed differently, and generates a valve control qualified signal or a valve control unqualified signal, and sends the valve control unqualified signal to the remote monitoring center, and sends the valve control qualified signal to the pipeline pressure inspection module;

[0009] The pipeline pressure inspection module monitors the pressure at several locations in the pipeline in real time through a pressure sensor, analyzes the collected pressure data when receiving a valve control failure signal, identifies abnormal pressure conditions in the pipeline through analysis, generates a pressure inspection failure signal when an abnormal pressure condition is identified, and sends the pressure inspection failure signal to the remote monitoring center. The remote monitoring center issues a corresponding warning when receiving a valve control failure signal or a pressure inspection failure signal;

[0010] The pipeline risk comprehensive assessment module conducts a comprehensive analysis of the management risk of the pipeline, generates a pipeline high-intensity management signal or a pipeline low-intensity management signal through analysis, and sends the pipeline high-intensity management signal or the pipeline low-intensity management signal to the remote monitoring center.

[0011] Furthermore, the specific analysis process of the valve opening and closing detection module includes:

[0012] The status of all valves on the pipeline is obtained. If the corresponding valve should be in a closed state but is actually in an open state, or should be in an open state but is actually in a closed state, the corresponding valve is assigned a status judgment symbol YP-1;

[0013] If the corresponding valve is not assigned the state judgment symbol YP-1 and is in the open state, the opening of the corresponding valve is collected, and the deviation value of the opening of the corresponding valve compared with the set standard opening is marked as the valve opening value, and the valve opening value is numerically compared with the preset valve opening threshold value. If the valve opening value exceeds the preset valve opening threshold value, the state judgment symbol YP-2 is assigned to the corresponding valve;

[0014] If the corresponding valve is assigned YP-1 or YP-2, the corresponding valve will be marked as an opening and closing valve with different opening and closing tables; if there is an opening and closing valve with different opening and closing tables on the pipeline, a valve control failure signal will be generated;

[0015] If there are no valves with different opening and closing modes on the pipeline, the valve condition values ​​of all valves that are not assigned the status judgment symbol YP-1 and are in the open state are averaged to obtain the valve analysis value, and the valve condition value with the largest value is marked as the valve opening amplitude value. The valve risk value is obtained by numerically calculating the valve analysis value and the valve opening amplitude value. The valve risk value is numerically compared with the preset valve risk threshold. If the valve risk value exceeds the preset valve risk threshold, a valve control failure signal is generated; if the valve risk value does not exceed the preset valve risk threshold, a valve control qualified signal is generated.

[0016] Furthermore, the specific analysis process of the pipeline risk comprehensive assessment module includes:

[0017] A detection period is set, the number of times a valve control failure signal is generated and the number of times a pressure test failure signal is generated during the detection period are obtained, and the number of times a valve control failure signal is generated and the number of times a pressure test failure signal is generated are summed up to obtain a pipeline early warning value;

[0018] The valve quality inspection value and valve control efficiency value are obtained, and the pipeline early warning value, valve quality inspection value and valve control efficiency value are numerically compared with the preset pipeline early warning threshold, the preset valve quality inspection threshold and the preset valve control efficiency threshold. If the pipeline early warning value, valve quality inspection value or valve control efficiency value exceeds the corresponding preset threshold, a pipeline high-intensity management signal is generated;

[0019] If the pipeline early warning value, valve quality inspection value and valve control effectiveness value do not exceed the corresponding preset threshold values, the pipeline early warning value, valve quality inspection value and valve control effectiveness value are numerically calculated to obtain the pipeline risk comprehensive inspection coefficient, and the pipeline risk comprehensive inspection coefficient is numerically compared with the preset pipeline risk comprehensive inspection coefficient threshold. If the pipeline risk comprehensive inspection coefficient exceeds the preset pipeline risk comprehensive inspection coefficient threshold, a pipeline high-intensity management signal is generated; if the pipeline risk comprehensive inspection coefficient does not exceed the preset pipeline risk comprehensive inspection coefficient threshold, a pipeline low-intensity management signal is generated.

[0020] Furthermore, the pipeline risk comprehensive assessment module is connected to the valve quality degradation inspection module and the valve control efficiency detection module in communication. The valve quality degradation inspection module analyzes the quality degradation status of all valves on the pipeline, obtains the valve quality inspection value through analysis, and sends the valve quality inspection value to the pipeline risk comprehensive assessment module;

[0021] The valve control efficiency detection module analyzes the remote control efficiency status of all valves on the pipeline during the detection period, obtains the valve control efficiency value through analysis, and sends the valve control efficiency value to the pipeline risk comprehensive assessment module.

[0022] Furthermore, the specific analysis process of the valve quality degradation inspection module includes:

[0023] The valve degradation value of the corresponding valve is obtained through valve operation summary analysis, and the valve degradation values ​​of all valves on the pipeline are averaged to obtain the valve degradation value, and the valve degradation value is numerically compared with the preset valve degradation threshold. If the valve degradation value exceeds the preset valve degradation threshold, the corresponding valve is marked as a dangerous valve, and the proportion of dangerous valves on the pipeline is marked as the valve dangerous inspection value;

[0024] And mark the valve degradation value with the largest numerical value as the valve degradation amplitude value, and obtain the valve quality inspection value by numerically calculating the valve degradation table value, valve danger table value and valve degradation amplitude value.

[0025] Furthermore, the specific analysis process of valve operation summary analysis is as follows:

[0026] Through analysis, it is determined in real time whether the position of the corresponding valve in the pipeline is in a medium-high damage state, the total duration of the corresponding valve in the medium-high damage state in the historical stage is obtained and marked as the medium-high damage time analysis value, and the single duration in the medium-high damage state is numerically compared with the preset single duration threshold. If the single duration exceeds the preset single duration threshold, the corresponding single duration is marked as the timeout duration, and the number of timeout durations corresponding to the corresponding valve in the historical stage is marked as the medium-high loss risk value;

[0027] The production time of the corresponding valve is collected, and the interval between the production time and the current time is marked as the valve production time value, and the total number of opening and closing adjustments for the corresponding valve in the historical stage is marked as the opening and closing frequency modulation value. The valve performance degradation value of the corresponding valve is obtained by numerically calculating the medium high loss time analysis value, the medium high loss risk value, the valve production time value and the opening and closing frequency modulation value.

[0028] Furthermore, the analysis and judgment method of the medium high damage state is as follows:

[0029] The position of the corresponding valve in the pipeline is obtained and marked as the target position, the medium pressure and medium temperature at the corresponding target position are collected and marked as the medium pressure inspection value and the medium temperature inspection value respectively, and the particulate matter content and medium corrosiveness intensity in the medium at the corresponding target position are collected and marked as the medium impurity value and the medium corrosion value respectively;

[0030] The medium damage value is obtained by numerically calculating the medium pressure inspection value, medium temperature inspection value, medium impurity value and medium corrosion value, and the medium damage value is numerically compared with the preset medium damage threshold. If the medium damage value exceeds the preset medium damage threshold, it is judged that the corresponding target position is currently in a high medium damage state.

[0031] Furthermore, the specific analysis process of the valve control efficiency detection module is as follows:

[0032] All control instructions issued by the remote monitoring center to the valves on the pipeline during the detection period are obtained. If the corresponding valve completes the operation of the corresponding control instruction within the corresponding specified time, the high-efficiency command execution symbol TP-1 is assigned. When the high-efficiency command execution symbol TP-1 is assigned, the actual time for the corresponding valve to complete the operation of the corresponding control instruction is collected and the difference between the actual time and the specified time is marked as the advance time;

[0033] The number of times the high-efficiency command execution symbol is generated during the detection period is obtained and the ratio is calculated with the total number of control instructions sent to obtain the high-efficiency command detection value, and the average of all advance time in the detection period is calculated to obtain the instruction advance time value; the valve control efficiency value is obtained by numerically calculating the high-efficiency command detection value and the instruction advance time value.

In the present invention, the opening and closing conditions of all valves on the pipeline are analyzed by the valve opening and closing detection module, and the opening and closing of abnormal valves is identified through analysis and a valve control qualified signal or a valve control unqualified signal is generated. When the valve control qualified signal is generated, the abnormal pressure condition in the pipeline is analyzed by the pipeline pressure inspection module, and when the valve control unqualified signal or the pressure inspection unqualified signal is generated, the remote management personnel are reminded to quickly take corresponding improvement measures, which is conducive to ensuring the safe operation of the pipeline;

[0037] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings;

[0038] Figure 1 This is a system block diagram of Embodiment 1 of the present invention;

[0039] Figure 2 This is a system block diagram of Embodiment 2 and Embodiment 3 of the present invention. DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Embodiment 1: Figure 1 As shown, the present invention proposes an intelligent pressure inspection system for valve pipelines, including a valve opening and closing detection module, a pipeline pressure inspection module, a pipeline risk comprehensive assessment module and a remote monitoring center;

[0042] The valve opening and closing detection module obtains all valves on the required monitoring pipeline, analyzes the opening and closing status of the corresponding valves, identifies the opening and closing valves of different tables through analysis, and generates a valve control qualified signal or a valve control unqualified signal, and sends the valve control unqualified signal to the remote monitoring center;

[0043] When the remote monitoring center receives a signal that the valve control is unqualified, it will issue a corresponding warning, and can monitor the control status of all valves on the pipeline in real time and provide accurate feedback to remind remote management personnel to take corresponding improvement measures in time, thereby ensuring the safe operation of the pipeline; the specific analysis process of the valve opening and closing detection module is as follows:

[0044] The status of all valves on the pipeline is obtained (including open and closed status). If the corresponding valve should be in a closed state but is actually in an open state, or should be in an open state but is actually in a closed state, indicating that the corresponding valve is abnormal, the corresponding valve is assigned a status judgment symbol YP-1;

[0045] If the corresponding valve is not assigned the state judgment symbol YP-1 and is in the open state, the opening of the corresponding valve is collected, and the deviation value of the opening of the corresponding valve compared with the set standard opening is marked as the valve opening value, and the valve opening value is numerically compared with the preset valve opening threshold value. If the valve opening value exceeds the preset valve opening threshold value, indicating that the corresponding valve is abnormal, the state judgment symbol YP-2 is assigned to the corresponding valve;

[0046] If the corresponding valve is assigned YP-1 or YP-2, the corresponding valve will be marked as a valve with different opening and closing tables; if there are valves with different opening and closing tables on the pipeline, it indicates that there is a problem with the current control of all valves on the pipeline, and a valve control failure signal is generated;

[0047] If there is no valve with different opening and closing values ​​on the pipeline, the valve opening values ​​of all valves that are not assigned the state judgment symbol YP-1 and are in the open state are averaged to obtain the valve opening value, and the valve opening value with the largest value is marked as the valve opening amplitude value;

[0048] The valve risk value QX is obtained by numerically calculating the valve analysis value QK and the valve opening amplitude value QF through the formula QX=(c1*QK+c2*QF) / 2; wherein c1 and c2 are preset weight coefficients, c1>c2>0; and the larger the value of the valve risk value QX, the worse the overall control performance of all valves on the pipeline;

[0049] The valve danger value QX is numerically compared with the preset valve danger threshold. If the valve danger value QX exceeds the preset valve danger threshold, it indicates that the control performance of all valves on the pipeline is poor overall, and a valve control unqualified signal is generated; if the valve danger value QX does not exceed the preset valve danger threshold, it indicates that the control performance of all valves on the pipeline is good overall, and a valve control qualified signal is generated.

[0050] The pipeline pressure inspection module monitors the pressure at several locations in the pipeline in real time through the pressure sensor. The valve opening and closing detection module sends the valve control qualified signal to the pipeline pressure inspection module. When the valve control unqualified signal is received, the collected pressure data is analyzed (including historical data comparison, trend analysis, abnormal value detection, etc., through data analysis, potential abnormal problems in the pipeline, such as pressure fluctuations, abnormal pressure increases, etc.) can be identified, and the abnormal pressure condition in the pipeline can be identified through analysis;

[0051] When an abnormal pressure condition is identified, a pressure test failure signal is generated and sent to the remote monitoring center. When the remote monitoring center receives the pressure test failure signal, it will issue a corresponding warning. It can identify abnormal pipeline pressure conditions in real time and issue timely warnings to remind remote management personnel to quickly make corresponding improvement measures to further ensure the safe operation of the pipeline.

[0052] The pipeline risk comprehensive assessment module conducts a comprehensive analysis of the management risk of the pipeline, generates a pipeline high-intensity management signal or a pipeline low-intensity management signal through analysis, and sends the pipeline high-intensity management signal or the pipeline low-intensity management signal to the remote monitoring center. When the remote monitoring center receives the pipeline high-intensity management signal, it will strengthen the operation supervision of the pipeline in the future, facilitate the reasonable planning and formulation of the subsequent management plan of the pipeline, and significantly reduce the subsequent operation risk of the pipeline. The specific analysis process of the pipeline risk comprehensive assessment module is as follows:

[0053] A detection period is set, preferably, the detection period is thirty days; the number of times the valve control unqualified signal is generated and the number of times the pressure test unqualified signal is generated within the detection period are obtained, and the number of times the valve control unqualified signal is generated and the number of times the pressure test unqualified signal is generated are summed up to obtain the pipeline early warning value GY;

[0054] After obtaining the valve quality inspection value GN and the valve control efficiency value GS, the pipeline early warning value GY, the valve quality inspection value GN and the valve control efficiency value GS are numerically compared with the preset pipeline early warning threshold, the preset valve quality inspection threshold and the preset valve control efficiency threshold. If the pipeline early warning value GY, the valve quality inspection value GN or the valve control efficiency value GS exceeds the corresponding preset threshold, it indicates that the management risk of the pipeline is relatively high and the subsequent supervision of the pipeline needs to be strengthened, then a pipeline high-intensity management signal is generated;

[0055] If the pipeline warning value GY, valve quality inspection value GN and valve control efficiency value GS do not exceed the corresponding preset thresholds, then the formula The pipeline early warning value GY, valve quality inspection value GN and valve control efficiency value GS are numerically calculated to obtain the pipeline risk comprehensive inspection coefficient GZ; wherein hp1, hp2 and hp3 are preset proportional coefficients with values ​​greater than zero, and the larger the value of the pipeline risk comprehensive inspection coefficient GZ is, the greater the overall risk of operation and management of the corresponding pipeline is, and the more supervision of the corresponding pipeline needs to be strengthened;

[0056] The pipeline risk comprehensive inspection coefficient GZ is numerically compared with the preset pipeline risk comprehensive inspection coefficient threshold. If the pipeline risk comprehensive inspection coefficient exceeds the preset pipeline risk comprehensive inspection coefficient threshold, it indicates that the overall operation management risk of the corresponding pipeline is relatively large, and it is necessary to strengthen the supervision of the corresponding pipeline in a timely manner, then a pipeline high-intensity management signal is generated; if the pipeline risk comprehensive inspection coefficient GZ does not exceed the preset pipeline risk comprehensive inspection coefficient threshold, it indicates that the overall operation management risk of the corresponding pipeline is relatively small, then a pipeline low-intensity management signal is generated.

[0057] Embodiment 2: Figure 2 As shown, the difference between this embodiment and the first embodiment is that the pipeline risk comprehensive assessment module is connected to the valve quality degradation inspection module in communication, and the valve quality degradation inspection module analyzes the quality degradation status of all valves on the pipeline, obtains the valve quality inspection value GN through analysis, and sends the valve quality inspection value GN to the pipeline risk comprehensive assessment module, which can not only accurately feedback the overall quality degradation status of the valves on the pipeline, but also provide data support for the analysis process of the pipeline risk comprehensive assessment module, thereby ensuring the accuracy of its analysis results; the specific analysis process of the valve quality degradation inspection module is as follows:

[0058] The valve performance degradation value of the corresponding valve is obtained through valve operation summary analysis, specifically: the position of the corresponding valve in the pipeline is obtained and marked as the target position, the medium (i.e. the liquid being transported) pressure and medium temperature at the corresponding target position are collected and marked as the medium pressure inspection value and medium temperature inspection value respectively, and the particulate matter content (i.e. the data value of the concentration of solid particulate impurities in the medium) and the medium corrosiveness intensity (i.e. the data value of the deviation of the pH of the medium from the preset appropriate pH value) in the medium at the corresponding target position are collected and marked as the medium impurity value and medium corrosion value respectively;

[0059] The medium damage value FY is obtained by numerically calculating the medium pressure inspection value FN, the medium temperature inspection value FM, the medium impurity value FP and the medium corrosion value FH through the formula FY=(rw1*FN+rw2*FM+rw3*FP+rw4*FH) / 4; wherein rw1, rw2, rw3 and rw4 are preset proportional coefficients with values ​​greater than zero, and the larger the value of the medium damage value FY is, the greater the damage caused to the corresponding valve life by the medium condition at the corresponding target position in the pipeline;

[0060] The medium damage value FY is numerically compared with a preset medium damage threshold. If the medium damage value FY exceeds the preset medium damage threshold, it is determined that the corresponding target position is currently in a medium high damage state;

[0061] The total duration of the corresponding valve in the medium high damage state in the historical stage is obtained and marked as the medium high damage time analysis value, and the single duration in the medium high damage state is numerically compared with the preset single duration threshold. If the single duration exceeds the preset single duration threshold, the corresponding single duration is marked as the timeout duration, and the number of timeout durations corresponding to the corresponding valve in the historical stage is marked as the medium high loss risk value;

[0062] The production time of the corresponding valve is collected, and the interval between the production time and the current time is marked as the valve production time value, and the total number of opening and closing adjustments for the corresponding valve in the historical stage (that is, the data value of the sum of the number of openings, the number of closings, and the number of opening adjustment times) is marked as the opening and closing frequency modulation value;

[0063] The medium high loss time analysis value XF, medium high loss risk value XG, valve production time value XS and opening and closing frequency modulation value XW are numerically calculated by the formula XP=my2*XG+(my1*XF+my3*XS+my4*XW) / my2 to obtain the valve performance degradation value XP of the corresponding valve; wherein my1, my2, my3 and my4 are preset proportional coefficients, my2>my4>my1>my3>0; and the larger the value of the valve performance degradation value XP, the worse the life condition of the corresponding valve is in general;

[0064] The valve degradation values ​​of all valves on the pipeline are averaged to obtain the valve degradation value, and the valve degradation value is numerically compared with the preset valve degradation threshold. If the valve degradation value exceeds the preset valve degradation threshold, it indicates that the life condition of the corresponding valve is generally poor, and the corresponding valve is marked as a dangerous valve, and the proportion of the number of dangerous valves on the pipeline is marked as the valve dangerous inspection value, and the valve degradation value with the largest value is marked as the valve degradation amplitude value;

[0065] The valve quality inspection value GN is obtained by numerically calculating the valve drop meter value HX, the valve danger meter value HW and the valve drop amplitude value HF through the formula GN=sw2*HW+(sw1*HX+sw3*HF) / 2; wherein, sw1, sw2, sw3 are preset proportional coefficients, sw2>sw1>sw3>0; and, the larger the value of the valve quality inspection value GN is, the worse the overall quality condition of the valves on the pipeline is, and the greater the adverse impact on the safety of pipeline operation is.

[0066] Embodiment 3: Figure 2 As shown, the difference between this embodiment and the first and second embodiments is that the pipeline risk comprehensive assessment module is connected to the valve control efficiency detection module in communication. The valve control efficiency detection module analyzes the remote control efficiency status of all valves on the pipeline during the detection period, obtains the valve control efficiency value GS through analysis, and sends the valve control efficiency value GS to the pipeline risk comprehensive assessment module, which can not only accurately feedback the remote control execution efficiency status of all valves on the pipeline, but also provide data support for the analysis process of the pipeline risk comprehensive assessment module, and further ensure the accuracy of its analysis results; the specific analysis process of the valve control efficiency detection module is as follows:

[0067] All control instructions issued by the remote monitoring center to the valves on the pipeline during the detection period are obtained. If the corresponding valve completes the operation of the corresponding control instruction within the corresponding specified time, the high-efficiency command execution symbol TP-1 is assigned. When the high-efficiency command execution symbol TP-1 is assigned, the actual time for the corresponding valve to complete the operation of the corresponding control instruction is collected and the difference between the actual time and the specified time is marked as the advance time;

[0068] The number of times the efficient command execution symbol is generated during the detection period is obtained and the ratio thereof is calculated with the total number of times the control instruction is sent to obtain the efficient command detection value, and the average of all advance times during the detection period is calculated to obtain the instruction advance time value;

[0069] By formula The high-efficiency command detection value LP and the command lead time value LS are numerically calculated to obtain the valve control efficiency value GS; wherein, ny1 and ny2 are preset proportional coefficients, and the values ​​of ny1 and ny2 are both positive numbers; and, the larger the value of the valve control efficiency value GS, the worse the remote control execution efficiency of all valves on the pipeline during the detection period, and the greater the adverse impact on the safe operation of the pipeline.

[0070] The working principle of the present invention is as follows: when in use, the opening and closing conditions of all valves on the pipeline are analyzed through the valve opening and closing detection module, and the opening and closing of abnormal valves are identified through analysis to generate a valve control qualified signal or a valve control unqualified signal, and when the valve control qualified signal is generated, the abnormal pressure condition in the pipeline is analyzed through the pipeline pressure inspection module to determine whether to generate a pressure inspection unqualified signal, and when the valve control unqualified signal or the pressure inspection unqualified signal is generated, the remote monitoring center issues an early warning to remind the remote management personnel to quickly take corresponding improvement measures, which is conducive to ensuring the safe operation of the pipeline, and the management risk of the pipeline is comprehensively analyzed through the pipeline risk comprehensive assessment module, and a pipeline high-intensity management signal or a pipeline low-intensity management signal is generated through analysis, and when the pipeline high-intensity management signal is generated, the subsequent operation supervision of the pipeline is strengthened, which is convenient for the reasonable planning and formulation of the subsequent management plan of the pipeline, and the subsequent operation risk of the pipeline is significantly reduced, and the degree of intelligence is high.
