Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of computers, in particular to pressure detection technology, and specifically to a pipeline pressure early warning method and system, an electronic device, and a storage medium. BACKGROUND

[0002] The process tail gas treatment equipment (Local Scrubber) can effectively handle the harmful gas residues in the process, avoid the problems and accidents such as air pipe blockage, pipeline corrosion, leakage, fire and explosion, and stop production. Only when the air inlet pipeline is clean and unobstructed can the toxic and harmful gas enter the equipment and finally be treated into non-toxic and harmless gas. When the equipment is applied to CVD PSIN and DRY ETCH processes, dust accumulation at the air inlet is very easy to occur, so the pressure detection of the air inlet is particularly important. Dust can block the detection pipe. The current tail gas treatment equipment is provided with a pressure sensor at each air inlet. If direct detection is performed without increasing gas purging inside the detection pipeline, when the detection pipe is blocked but not completely blocked, the feedback value of the pressure sensor at this time is the same as that when it is not blocked, and the detection cannot truly and effectively feedback how much the detection port is blocked. Only when the air inlet or the detection pipe is completely blocked, the equipment will generate an alarm at this time. Therefore, the early warning capability of the current tail gas treatment equipment is poor. SUMMARY

[0042] In order to make the purpose, technical solutions and advantages of the application more clear, the technical solutions in the application will be described clearly and completely in the following with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are some embodiments of the application, but not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the application.

[0043] It should be noted that although the logical sequence is shown in the flowchart, under certain data, the steps shown or described can be completed in an order different from that shown.

[0044] Referring to Figure 1 , Figure 1 is a flowchart of a pipeline pressure early warning method provided by an embodiment of the present application. The pipeline pressure early warning method provided by an embodiment of the present application comprises the following steps.

[0045] In step 101, a first purge flow rate and a pipeline blockage early warning percentage set when the tail gas treatment equipment is running are obtained.

[0046] In step 102, the first purge flow rate and the pipeline blockage early warning percentage are input into a pressure control model to obtain a first early warning pressure value and a second early warning pressure value output by the pressure control model.

[0047] In step 103, a first pressure deviation value in the running process of the tail gas treatment equipment is obtained.

[0048] In step 104, a pipeline pressure early warning is issued based on the first pressure deviation value, the first early warning pressure value and the second early warning pressure value.

[0049] It should be noted that the pipeline pressure early warning method of the present embodiment is realized based on a tail gas treatment equipment. Referring to Figure 2 , Figure 2 is a structural diagram of a tail gas treatment equipment provided by an embodiment of the present application. The gas blowing pipe N2 passes through the mass flow controller 1 (MFC), the T-shaped tee joint 3 and the proportional valve 4 to blow gas to the detection pipe 5, flows into the detection pipeline 6, and the pressure sensor 2 detects the pressure value inside the pipeline through the T-shaped tee joint 3. The pipeline pressure deviation value ΔP of the T-shaped tee joint 3, the blowing flow rate Q of the gas blowing pipe N2 and the pipeline blockage percentage of the proportional valve 4 can all be adjusted according to the actual situation of the equipment or set through the control system.

[0050] Further, the present embodiment takes the pipeline pressure early warning system as an execution subject for illustration, but is not limited to the pipeline pressure early warning system.

[0051] When the pipeline pressure early warning is needed, the user needs to set the first purge flow rate and the pipeline blockage early warning percentage in the pipeline pressure early warning system, that is, to blow gas in the gas blowing pipe N2 with the first purge flow rate, and when the pipeline blockage degree of the detection pipe 5 reaches the pipeline blockage early warning percentage, the pipeline pressure early warning is issued.

[0052] Therefore, when pipeline pressure early warning is performed, the pipeline pressure early warning system acquires the first purge flow rate and the pipeline blockage early warning percentage set when the tail gas treatment equipment is running.

[0053] Further, the pipeline pressure early warning system inputs the first purge flow rate and the pipeline blockage early warning percentage into a pressure control model to obtain first and second early warning pressure values output by the pressure control model, wherein the first early warning pressure value is less than the second early warning pressure value, and the pressure control model is trained based on a purge flow rate training set and a pipeline blockage early warning percentage training set.

[0054] Further, the pipeline pressure early warning system acquires a first pressure deviation value in real time during the running of the tail gas treatment equipment, and compares the first pressure deviation value with the first and second early warning pressure values in real time to obtain a comparison result. Further, the pipeline pressure early warning system issues a pipeline pressure early warning according to the real-time comparison result.

[0055] The pipeline pressure early warning method provided by the embodiments of the present application acquires a first purge flow rate and a pipeline blockage early warning percentage set when a tail gas treatment equipment is running, inputs the first purge flow rate and the pipeline blockage early warning percentage into a pressure control model to obtain first and second early warning pressure values output by the pressure control model, acquires a first pressure deviation value during the running of the tail gas treatment equipment, and issues a pipeline pressure early warning based on the first pressure deviation value, the first and second early warning pressure values. In the process of pipeline pressure early warning, the purge flow rate and the pipeline blockage early warning percentage are set, and the early warning pressure values are output according to the pressure control model. When the pressure deviation value during the running of the tail gas treatment equipment reaches the early warning pressure value, a pipeline pressure early warning is issued, thereby solving the problem that an alarm is generated only when a detection pipe is completely blocked, and improving the early warning capability of the tail gas treatment equipment.

[0056] Further, the specific training process of the pressure control model includes:

[0057] acquiring an original pressure deviation value set; the original pressure deviation value set includes a plurality of second pressure deviation values;

[0058] dividing a percentage adjustment interval of a proportional valve into a preset number of proportional valve percentage intervals; the proportional valve percentage is inversely proportional to the pipeline blockage percentage;

[0059] acquiring a second purge flow rate of each proportional valve percentage interval at each second pressure deviation value;

[0060] training according to each second pressure deviation value, each proportional valve percentage interval of each second pressure deviation value, and the second purge flow rate of each proportional valve percentage interval at each second pressure deviation value to obtain the pressure control model.

[0061] Specifically, the pipeline pressure early warning system obtains a set of original pressure deviation values, the set of original pressure deviation values including a plurality of second pressure deviation values, such as second pressure deviation value ΔP1, second pressure deviation value ΔP2, and second pressure deviation value ΔP3.

[0062] Further, the pipeline pressure early warning system divides the percentage adjustment range of the proportional valve into a preset number of proportional valve percentage intervals, wherein the percentage of the proportional valve is inversely proportional to the percentage of the pipeline blockage. In an embodiment, the percentage adjustment range of the proportional valve is 0-100%, and one interval is divided for every 20% of blockage, thus obtaining five proportional valve percentage intervals, i.e., 0-20%, 20%-40%, 40%-60%, 60%-80%, and 80%-100%. Further, the pipeline pressure early warning system obtains a second purge flow rate of each proportional valve percentage interval at each second pressure deviation value.

[0063] The pipeline pressure early warning system trains the pressure control model according to each second pressure deviation value, each proportional valve percentage interval of each second pressure deviation value, and the second purge flow rate of each proportional valve percentage interval at each second pressure deviation value.

[0064] In an embodiment, the percentage adjustment range of the proportional valve 4 is 0-100%, and the blockage of the simulation detection pipe 5 is simulated by taking every 20% of blockage as a blockage interval. Because the pressure deviation value ΔP is caused by the blowing of the blowing pipe N2 inside the pipeline, after the purge flow rate is determined, the actual pressure deviation value needs to be offset by ΔP to ensure the accuracy of detection. The greater the purge gas flow rate, the more sensitive the reaction pipeline blockage.

[0065] The pressure deviation value ΔP1 is determined as nPa. At this time, the proportional valve 4 is fully opened, that is, the detection pipeline is not blocked, the MFC flow is adjusted, the ΔP1 reaches nPa, and the purge flow Q1 of the blowing pipe N2 at this time is obtained; the proportional valve 4 is adjusted to 80%, which is equivalent to that the detection pipeline is blocked by 20% at this time, the MFC flow is adjusted, the ΔP1 reaches nPa, and the purge flow Q2 of the blowing pipe N2 at this time is obtained. The proportional valve 4 is adjusted to 60%, which is equivalent to that the detection pipeline is blocked by 40% at this time, the MFC flow is adjusted, the ΔP1 reaches nPa, and the purge flow Q3 of the blowing pipe N2 at this time is obtained. The proportional valve 4 is adjusted to 40%, which is equivalent to that the detection pipeline is blocked by 60% at this time, the MFC flow is adjusted, the ΔP1 reaches nPa, and the purge flow Q4 of the blowing pipe N2 at this time is obtained. The proportional valve 4 is adjusted to 20%, which is equivalent to that the detection pipeline is blocked by 80% at this time, the MFC flow is adjusted, the ΔP1 reaches nPa, and the purge flow Q5 of the blowing pipe N2 at this time is obtained. The proportional valve 4 is adjusted to 0, which is equivalent to that the detection pipeline is blocked by 100% at this time, the MFC flow is adjusted, the ΔP1 reaches nPa, and the purge flow Q6 of the blowing pipe N2 at this time is obtained. Similarly, when the pressure deviation value ΔP2 is mPa, the purge flows of the detection pipeline blocked by 0, 20%, 40%, 60%, 80% and 100% are Q7, Q8, Q9, Q10, Q11 and Q12. Similarly, when the pressure deviation value ΔP3 is kPa, the purge flows of the detection pipeline blocked by 0, 20%, 40%, 60%, 80% and 100% are Q13, Q14, Q15, Q16, Q17 and Q18. For details, refer to Table 1, which is a gas purge flow table.

[0066] Table 1: Gas Purge Flow Table

[0067] Pressure deviation value \ % of blockage 0% 20% 40% 60% 80% 100% △P1 Q1 Q2 Q3 Q4 Q5 Q6 △P2 Q7 Q8 Q9 Q10 Q11 Q12 △P3 Q13 Q14 Q15 Q16 Q17 Q18

[0068] The pressure control model is trained, so that the pressure control model can output a warning pressure value. When the pressure deviation value in the running process of the tail gas treatment equipment reaches the warning pressure value, a pipeline pressure warning is issued, thereby solving the problem that an alarm is generated only when the detection pipeline is completely blocked, and improving the warning capability of the tail gas treatment equipment.

[0069] Further, the pressure control model is obtained by training each second pressure deviation value, each proportional valve percentage interval of each second pressure deviation value, and the second purge flow of each proportional valve percentage interval under each second pressure deviation value, and the pressure control model comprises the following steps.

[0070] A third purge flow is obtained by adjusting the proportional valve percentage to a preset value in the second purge flow.

[0071] obtaining the second pressure deviation value and the third pressure deviation value of each proportional valve percentage interval at each third purge flow rate;

[0072] training according to each third purge flow rate, each proportional valve percentage interval at each third purge flow rate, and the second pressure deviation value and the third pressure deviation value of each proportional valve percentage interval at each third purge flow rate to obtain the pressure control model.

[0073] Specifically, the pipeline pressure early warning system obtains the third purge flow rate in the second purge flow rate with the proportional valve percentage being a preset value, and the preset value is set according to the demand. In an embodiment, the preset value is 0, that is, the third purge flow rate in the second purge flow rate with the proportional valve percentage being 0 is obtained.

[0074] Further, the pipeline pressure early warning system obtains the second pressure deviation value and the third pressure deviation value of each proportional valve percentage interval at each third purge flow rate, and trains according to each third purge flow rate, each proportional valve percentage interval at each third purge flow rate, and the second pressure deviation value and the third pressure deviation value of each proportional valve percentage interval at each third purge flow rate to obtain the pressure control model.

[0075] In an embodiment, the preset value is 0, and the third purge flow rate can be Q1, Q7 and Q13. Therefore, the purge flow rates Q1, Q7 and Q13 are used to determine the detection pressure difference table of the pipeline. When the purge flow rate is fixed as Q1 and the percentage of the proportional valve 4 is adjusted to be 0%, 20%, 40%, 60%, 80% and 100% respectively, the pressure deviation values ΔP1, ΔP4, ΔP7, ΔP10, ΔP13 and ΔP16 can be obtained. Similarly, when the purge flow rate is fixed as Q7 and the percentage of the proportional valve 4 is adjusted to be 0%, 20%, 40%, 60%, 80% and 100% respectively, the pressure deviation values ΔP2, ΔP5, ΔP8, ΔP11, ΔP14 and ΔP17 can be obtained. When the purge flow rate is fixed as Q13 and the percentage of the proportional valve 4 is adjusted to be 0%, 20%, 40%, 60%, 80% and 100% respectively, the pressure deviation values ΔP3, ΔP6, ΔP9, ΔP12, ΔP15 and ΔP18 can be obtained. Therefore, the detection pressure difference table is obtained, and the detection pressure difference table is the pressure control model. Referring to Table 2, Table 2 is the detection pressure difference table.

[0076] Table 2 Detection pressure difference table

[0077] Sweep flow \ % of blockage 0% 20% 40% 60% 80% 100% Q1 △P1 △P4 △P7 △P10 △P13 △P16 Q7 △P2 △P5 △P8 △P11 △P14 △P17 Q13 △P3 △P6 △P9 △P12 △P15 △P18

[0078] Therefore, in an embodiment, the tail gas treatment equipment is running, the first purge flow Q1 is set, the pipeline blockage early warning percentage is 60%, the first early warning pressure value and the second early warning pressure value are obtained according to the pressure control model, the first pressure deviation value ΔP in the running process of the tail gas treatment equipment, and whether ΔP is between the first early warning pressure value and the second early warning pressure value is judged in real time, and the value is taken upward, when ΔP > ΔP7, an alarm prompt is generated at this time that 60% has been blocked.

[0079] The pressure control model is trained in the embodiment of the application, so that the early warning pressure value can be output through the pressure control model, the pipeline pressure early warning is issued when the pressure deviation value in the running process of the tail gas treatment equipment reaches the early warning pressure value, the problem that the alarm is generated only when the detection pipe is completely blocked is solved, and the early warning capability of the tail gas treatment equipment is improved.

[0080] Further, the pipeline pressure early warning issued based on the first pressure deviation value, the first early warning pressure value and the second early warning pressure value in step 104 comprises:

[0081] If it is determined that the first pressure deviation value is greater than the first early warning pressure value, a first pipeline pressure early warning is issued, and the equipment state of the tail gas treatment equipment is controlled to be in a running state;

[0082] A second pipeline pressure early warning is issued based on the first purge flow and the second early warning pressure value; or

[0083] If it is determined that the first pressure deviation value is greater than the first early warning pressure value, a third pipeline pressure early warning is issued, and the equipment state of the tail gas treatment equipment is switched from a running state to a down state.

[0084] Specifically, for the case of early warning without shutdown:

[0085] If it is determined that the first pressure deviation value is greater than the first early warning pressure value, the pipeline pressure early warning system issues a first pipeline pressure early warning, at this time, the tail gas treatment equipment continues to run, that is, the equipment state of the tail gas treatment equipment is controlled to remain in a running state.

[0086] Further, the pipeline pressure early warning system adjusts the first purge flow, and a second pipeline pressure early warning is issued based on the adjusted first purge flow and the second early warning pressure value.

[0087] For the case of early warning with shutdown:

[0088] If it is determined that the first pressure deviation value is greater than the first early warning pressure value, the pipeline pressure early warning system issues a third pipeline pressure early warning, at this time, the tail gas treatment equipment needs to be down, that is, the equipment state of the tail gas treatment equipment is switched from a running state to a down state.

[0089] The embodiment of the present application controls the pipeline pressure warning in various ways, and improves the flexibility of the pipeline pressure warning.

[0090] Further, a second pipeline pressure warning is issued based on the first purge flow and the second warning pressure value, including:

[0091] The first purge flow is adjusted to a fourth purge flow;

[0092] A fourth pressure deviation value during the operation of the tail gas treatment equipment at the fourth purge flow is obtained;

[0093] If it is determined that the fourth pressure deviation value is greater than or equal to the second warning pressure value, a second pipeline pressure warning is issued.

[0094] Specifically, the pipeline pressure warning system adjusts the first purge flow to the fourth purge flow, and obtains a fourth pressure deviation value during the operation of the tail gas treatment equipment at the fourth purge flow.

[0095] Further, if it is determined that the fourth pressure deviation value is greater than or equal to the second warning pressure value, the pipeline pressure warning system issues a second pipeline pressure warning, at this time, the tail gas treatment equipment needs to be shut down, so the device state of the tail gas treatment equipment is switched from the running state to the shutdown state. Further, if it is determined that the fourth pressure deviation value is less than the second warning pressure value, the pipeline pressure warning system obtains the fourth pressure deviation value in real time for pipeline pressure warning.

[0096] The embodiment of the present application controls the pipeline pressure warning in various ways, and improves the flexibility of the pipeline pressure warning.

[0097] Therefore, it can be understood that the overall scheme of the embodiment of the present application is to determine the change of the passageway of the detection pipe 5 and the blockage condition of the detection pipe 5 by cooperating the purge flow of the pressure sensor 2 and the blowing pipe N2, so as to generate a blockage warning and output a blockage percentage alarm, thereby providing data judgment for the operator whether to maintain the equipment, and being more intuitive and effective.

[0098] At the same time, the operator can set through the controller whether to shut down when the equipment blockage warning occurs, or select the blockage percentage of the equipment warning, that is, select when the detection pipe is blocked to a certain percentage, the equipment generates an alarm.
