[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 2023110892451, filed on August 28, 2023, entitled “Pipeline Pressure Early Warning Method, System, Electronic Device and Storage Medium,” which is incorporated herein by reference in its entirety. Technical Field

[0003] The present application relates to the field of computer technology, in particular to pressure detection technology, and specifically to a pipeline pressure early warning method, system, electronic device and storage medium. Background Art

[0004] Process exhaust gas treatment equipment (Local Scrubber) effectively removes harmful residual gases from the process, preventing problems such as duct blockage, corrosion, leaks, fires, explosions, and production stoppages. Ensuring clean and unobstructed air intake pipes allows toxic gases to enter the equipment and be treated as harmless gases. When used in processes such as CVD PSIN and Dry Etch, dust easily accumulates at the air intake, making inlet pressure monitoring particularly important. Dust can clog the detection tubes. Current exhaust gas treatment equipment is equipped with a pressure sensor at each air intake. Direct monitoring, without additional gas purge inside the detection tubes, results in the same pressure sensor feedback value when the detection tubes are partially blocked, providing no accurate and reliable information on the extent of the blockage. The equipment only generates an alarm when the air intake or detection tube is completely blocked. Consequently, current exhaust gas treatment equipment has limited early warning capabilities.

[0045] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0046] The embodiments of the present application provide an embodiment of a pipeline pressure early warning method. It should be noted that although a logical order is shown in the flow chart, under certain data, the steps shown or described may be completed in an order different from that shown here.

[0047] 1 is a flow chart 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 includes the following steps.

[0048] Step 101 : obtaining a first purge flow rate and a pipeline blockage warning percentage set when the exhaust gas treatment equipment is in operation.

[0049] Step 102 : Input the first purge flow rate and the pipeline blockage warning percentage into a pressure control model to obtain a first warning pressure value and a second warning pressure value output by the pressure control model.

[0050] Step 103: Acquire a first pressure deviation value during the operation of the exhaust gas treatment equipment.

[0051] Step 104: issuing a pipeline pressure warning based on the first pressure deviation value, the first warning pressure value, and the second warning pressure value.

[0052] It should be noted that the pipeline pressure warning method of this embodiment is implemented based on the exhaust gas treatment equipment. Referring to Figure 2, Figure 2 is a schematic structural diagram of the exhaust gas treatment equipment provided in the embodiment of the present application. The air blowing pipe N2 passes through the mass flow controller 1 (Mass Flow Controller, MFC) through the T-type tee 3 and the proportional valve 4 to the detection pipe 5 to blow air into the detection pipe 6. The pressure sensor 2 detects the pressure value inside the pipeline through the T-type tee 3. The pipeline pressure deviation value ΔP of the T-type tee 3, the air blowing pipe N2 purge flow rate Q, 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.

[0053] Furthermore, the embodiments of the present application are illustrated by taking a pipeline pressure early warning system as an execution subject, but are not limited to a pipeline pressure early warning system.

[0054] When a pipeline pressure warning is required, the user needs to set the first purge flow rate and the pipeline blockage warning percentage in the pipeline pressure warning system, that is, to blow air in the blowing pipe N2 at the first purge flow rate. When the pipeline blockage degree of the detection pipe 5 reaches the pipeline blockage warning percentage, a pipeline pressure warning is issued.

[0055] Therefore, when performing pipeline pressure warning, the pipeline pressure warning system obtains the first purge flow rate and pipeline blockage warning percentage set when the exhaust gas treatment equipment is running.

[0056] Furthermore, the pipeline pressure warning system inputs the first purge flow and the pipeline blockage warning percentage into the pressure control model to obtain the first warning pressure value and the second warning pressure value output by the pressure control model, wherein the first warning pressure value is less than the second warning pressure value, and the pressure control model is trained based on the purge flow training set and its pipeline blockage warning percentage training set.

[0057] Furthermore, the pipeline pressure warning system obtains a first pressure deviation value during the operation of the exhaust gas treatment equipment in real time, and compares the first pressure deviation value with the first warning pressure value and the second warning pressure value in real time to obtain a comparison result. Furthermore, the pipeline pressure warning system issues a pipeline pressure warning based on the real-time comparison result.

[0058] The pipeline pressure warning method provided in the embodiment of the present application obtains the first purge flow rate and pipeline blockage warning percentage set during the operation of the exhaust gas treatment equipment; inputs the first purge flow rate and pipeline blockage warning percentage into the pressure control model to obtain the first warning pressure value and the second warning pressure value output by the pressure control model; obtains the first pressure deviation value during the operation of the exhaust gas treatment equipment; and issues a pipeline pressure warning based on the first pressure deviation value, the first warning pressure value and the second warning pressure value. In the process of pipeline pressure warning, by setting the purge flow rate and the pipeline blockage warning percentage, and then outputting the warning pressure value according to the pressure control model, when the pressure deviation value during the operation of the exhaust gas treatment equipment reaches the warning pressure value, a pipeline pressure warning is issued, which solves the problem that the alarm will only be generated when the detection pipe is completely blocked, and improves the warning capability of the exhaust gas treatment equipment.

[0059] Furthermore, the specific training process of the pressure control model includes:

[0060] Acquire an original pressure deviation value set; the original pressure deviation value set includes a plurality of second pressure deviation values;

[0061] The percentage adjustment range of the proportional valve is divided into a preset number of proportional valve percentage intervals; the proportional valve percentage is inversely proportional to the pipeline blockage percentage;

[0062] Obtaining a second purge flow rate for each proportional valve percentage interval at each second pressure deviation value;

[0063] The pressure control model is obtained by training according to 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 at each second pressure deviation value.

[0064] Specifically, the pipeline pressure early warning system obtains an original pressure deviation value set, which includes multiple second pressure deviation values, such as the multiple second pressure deviation values ​​respectively being a second pressure deviation value ΔP1, a second pressure deviation value ΔP2, and a second pressure deviation value ΔP3.

[0065] Furthermore, the pipeline pressure warning system divides the percentage adjustment range of the proportional valve into a preset number of proportional valve percentage intervals, wherein the proportional valve percentage is inversely proportional to the pipeline blockage percentage. In one embodiment, the proportional valve percentage adjustment range is 0-100%, and one interval is divided every 20% of blockage, thereby obtaining five proportional valve percentage intervals, namely 0-20%, 20%-40%, 40%-60%, 60%-80%, and 80%-100%. Furthermore, the pipeline pressure warning system obtains a second purge flow rate for each proportional valve percentage interval at each second pressure deviation value;

[0066] The pipeline pressure early warning system is trained according to 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 to obtain a pressure control model.

[0067] In one embodiment, the proportional valve 4 has a percentage adjustment range of 0-100%, simulating the blockage of the detection tube 5, with each 20% blockage interval used as the blockage interval for illustration. Because the pressure deviation ΔP is caused by N2 purge from the internal pipeline, after determining the purge flow rate, the actual pressure deviation value needs to be offset by ΔP to ensure detection accuracy. A higher purge gas flow rate increases sensitivity to pipeline blockage.

[0068] Determine the pressure deviation ΔP1 to be n Pa. At this point, proportional valve 4 is fully open, indicating that the detection line is unobstructed. Adjust the MFC flow rate to achieve ΔP1 at n Pa, and obtain the purge flow rate Q1 of the blow pipe N2. Adjust proportional valve 4 to 80%, which corresponds to a 20% blockage in the detection line. Adjust the MFC flow rate to achieve ΔP1 at n Pa, and obtain the purge flow rate Q2 of the blow pipe N2. Adjust proportional valve 4 to 60%, which corresponds to a 40% blockage in the detection line. Adjust the MFC flow rate to achieve ΔP1 at n Pa, and obtain the purge flow rate Q3 of the blow pipe N2. Adjust proportional valve 4 to 40%, which corresponds to a 60% blockage in the detection line. Adjust the MFC flow rate to achieve ΔP1 at n Pa, and obtain the purge flow rate Q4 of the blow pipe N2. Adjust proportional valve 4 to 20%, which corresponds to an 80% blockage in the detection line. Adjust the MFC flow rate to achieve ΔP1 at n Pa, and obtain the purge flow rate Q5 of the blow pipe N2. Adjusting proportional valve 4 to 0% is equivalent to detecting a 100% blockage in the pipeline. Adjusting the MFC flow rate to bring ΔP1 to n Pa yields the purge flow rate Q6 for gas pipe N2. Similarly, when the pressure deviation ΔP2 is m Pa, the purge flows for detection pipeline blockages of 0%, 20%, 40%, 60%, 80%, and 100% are Q7, Q8, Q9, Q10, Q11, and Q12. Similarly, when the pressure deviation ΔP3 is k Pa, the purge flows for detection pipeline blockages of 0%, 20%, 40%, 60%, 80%, and 100% are Q13, Q14, Q15, Q16, Q17, and Q18. For details, refer to Table 1, which shows the gas purge flow rate table.

[0069] Table 1 Gas purge flow table

[0070] The embodiment of the present application trains a pressure control model so that a warning pressure value can be output through the pressure control model. When the pressure deviation value during the operation of the exhaust gas treatment equipment reaches the warning pressure value, a pipeline pressure warning is issued, which solves the problem that an alarm is only generated when the detection pipe is completely blocked, and improves the warning capability of the exhaust gas treatment equipment.

[0071] Furthermore, the pressure control model is obtained by 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 under each second pressure deviation value, including:

[0072] Obtaining a third purge flow rate in which the percentage of the proportional valve in the second purge flow rate is a preset value;

[0073] Obtaining a second pressure deviation value and a third pressure deviation value for each percentage interval of the proportional valve at each third purge flow rate;

[0074] The pressure control model is obtained by training according to each third purge flow rate, each proportional valve percentage interval under each third purge flow rate, and the second pressure deviation value and the third pressure deviation value of each proportional valve percentage interval under each third purge flow rate.

[0075] Specifically, the pipeline pressure warning system obtains a third purge flow in which the proportional valve percentage in the second purge flow is a preset value. The preset value is set according to demand. In one embodiment, the preset value is 0, that is, the third purge flow in which the proportional valve percentage in the second purge flow is 0 is obtained.

[0076] Furthermore, the pipeline pressure warning system obtains the second pressure deviation value and the third pressure deviation value of each proportional valve percentage interval under each third purge flow rate, and trains according to each third purge flow rate, each proportional valve percentage interval under each third purge flow rate, and the second pressure deviation value and the third pressure deviation value of each proportional valve percentage interval under each third purge flow rate to obtain a pressure control model.

[0077] In one 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 pipeline's test differential pressure. With a fixed purge flow rate of Q1 and proportional valve 4 adjusted to 0%, 20%, 40%, 60%, 80%, and 100%, respectively, pressure deviations ΔP1, ΔP4, ΔP7, ΔP10, ΔP13, and ΔP16 can be obtained. Similarly, with a fixed purge flow rate of Q7 and proportional valve 4 adjusted to 0%, 20%, 40%, 60%, 80%, and 100%, respectively, pressure deviations ΔP2, ΔP5, ΔP8, ΔP11, ΔP14, and ΔP17 can be obtained. The fixed purge flow rate is Q13, and the percentages of the proportional valve 4 are adjusted to 0%, 20%, 40%, 60%, 80% and 100% respectively. The pressure deviation values ​​can be obtained as ΔP3, ΔP6, ΔP9, ΔP12, ΔP15 and ΔP18, so the detection differential pressure table is obtained. The detection differential pressure table is the pressure control model. Refer to Table 2, which is the detection differential pressure table.

[0078] Table 2 Detection pressure difference table

[0079] Therefore, in one embodiment, a first purge flow rate Q1 and a pipeline blockage warning percentage of 60% are set during operation of the exhaust gas treatment device. A first warning pressure value ΔP7 and a second warning pressure value ΔP10 are obtained according to the pressure control model. During operation of the exhaust gas treatment device, a first pressure deviation value ΔP is determined in real time to determine whether ΔP is between ΔP7 and ΔP10, with the value being taken upwards. If ΔP exceeds ΔP7, an alarm is generated indicating that the blockage has reached 60%.

[0080] The embodiment of the present application trains a pressure control model so that a warning pressure value can be output through the pressure control model. When the pressure deviation value during the operation of the exhaust gas treatment equipment reaches the warning pressure value, a pipeline pressure warning is issued, which solves the problem that an alarm is only generated when the detection pipe is completely blocked, and improves the warning capability of the exhaust gas treatment equipment.

[0081] Furthermore, issuing a pipeline pressure warning based on the first pressure deviation value, the first warning pressure value, and the second warning pressure value as recorded in step 104 includes:

[0082] If it is determined that the first pressure deviation value is greater than the first warning pressure value, a first pipeline pressure warning is issued, and the device state of the exhaust gas treatment device is controlled to be in an operating state;

[0083] issuing a second pipeline pressure warning based on the first purge flow rate and the second warning pressure value; or

[0084] If it is determined that the first pressure deviation value is greater than the first warning pressure value, a third pipeline pressure warning is issued, and the device state of the exhaust gas treatment device is controlled to switch from the running state to the shutdown state.

[0085] Specifically, when the warning does not cause a shutdown:

[0086] If it is determined that the first pressure deviation value is greater than the first warning pressure value, the pipeline pressure warning system issues a first pipeline pressure warning. At this time, the exhaust gas treatment equipment continues to operate, that is, the equipment state of the exhaust gas treatment equipment is controlled to remain in the operating state.

[0087] Furthermore, the pipeline pressure warning system adjusts the first purge flow rate and issues a second pipeline pressure warning according to the adjusted first purge flow rate and the second warning pressure value.

[0088] In case of early warning shutdown:

[0089] If it is determined that the first pressure deviation value is greater than the first warning pressure value, the pipeline pressure warning system will issue a third pipeline pressure warning. At this time, the exhaust gas treatment equipment needs to be shut down, that is, the equipment state of the exhaust gas treatment equipment is controlled to switch from the running state to the shutdown state.

[0090] The embodiments of the present application control pipeline pressure warning in various ways, thereby improving the flexibility of pipeline pressure warning.

[0091] Furthermore, issuing a second pipeline pressure warning based on the first purge flow rate and the second warning pressure value includes:

[0092] adjusting the first purge flow rate to a fourth purge flow rate;

[0093] Obtaining a second pressure deviation value of the exhaust gas treatment device during operation at the fourth purge flow rate;

[0094] If it is determined that the second pressure deviation value is greater than or equal to the second warning pressure value, a second pipeline pressure warning is issued.

[0095] Specifically, the pipeline pressure early warning system adjusts the first purge flow rate to a fourth purge flow rate, and obtains a second pressure deviation value when the exhaust gas treatment equipment operates at the fourth purge flow rate.

[0096] Furthermore, if it is determined that the second pressure deviation value is greater than or equal to the second warning pressure value, the pipeline pressure warning system will issue a second pipeline pressure warning. At this time, the exhaust gas treatment equipment needs to be shut down, and the equipment state of the exhaust gas treatment equipment is controlled to switch from the running state to the shutdown state. Furthermore, if it is determined that the second pressure deviation value is less than the second warning pressure value, the pipeline pressure warning system obtains the second pressure deviation value in real time and issues a pipeline pressure warning.

[0097] The embodiments of the present application control pipeline pressure warning in various ways, thereby improving the flexibility of pipeline pressure warning.

[0098] Therefore, it can be understood that the overall solution of the embodiment of the present application is to determine the diameter change of the detection tube 5 and the blockage condition of the detection tube 5 through the coordination of the pressure sensor 2 and the purge flow of the air pipe N2, thereby generating a blockage warning and outputting a blockage percentage alarm, providing the operator with data judgment on whether to maintain the equipment, which is more intuitive and effective.

[0099] At the same time, the operator can set the controller to choose whether to shut down the equipment when a blockage warning is issued, or to choose the blockage percentage of the equipment warning, that is, to choose the amount of blockage in the detection tube when the equipment will alarm.

[0100] The pipeline pressure warning system provided by the embodiment of the present application is described below. The pipeline pressure warning system described below and the pipeline pressure warning method described above can be referenced to each other.

In the process of pipeline pressure warning, by setting the purge flow rate and the pipeline blockage warning percentage, and then outputting the warning pressure value according to the pressure control model, when the pressure deviation value during the operation of the exhaust gas treatment equipment reaches the warning pressure value, a pipeline pressure warning is issued, which solves the problem that the alarm will only be generated when the detection pipe is completely blocked, and improves the warning capability of the exhaust gas treatment equipment.
