[0027] Embodiment 1

[0028] Figure 1 A flow chart of a method for determining the blockage time of a liquid delivery pipeline is provided for the first embodiment of the present application. The embodiment of the present application can be applied to the situation of identifying the blockage time of a chemical transportation pipeline. The method can be executed by a device for determining the blockage time of a liquid delivery pipeline. The device for determining the blockage time of a liquid delivery pipeline can be implemented in the form of hardware and / or software. The device for determining the blockage time of a liquid delivery pipeline can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes:

[0029] S110, continuously acquiring the pipeline flow rate obtained by the flow sensor detecting the target liquid delivery pipeline.

[0030] The target liquid delivery pipeline may be a pipeline for delivering chemicals, such as certain acidic liquids, alkaline liquids, etc. Since the target liquid delivery pipeline is used to deliver chemicals, impurities may appear on its inner wall, and the environment inside the pipeline is special (such as strong acid, strong alkali environment, etc.), and a flow sensor is usually required for flow detection.

[0031] Specifically, a sensor for detecting the flow rate of the target liquid delivery pipeline is pre-installed. After the target liquid delivery pipeline begins to be used, that is, after the liquid is transported through the pipeline, the pipeline flow rate detected by the flow sensor is continuously obtained. Since the pipeline flow rate is obtained in real time, as time goes by, more and more pipeline flow data is collected, and the pipeline flow rate can be fitted into a pipeline flow curve.

[0032] In the embodiment of the present application, since the impurities on the inner wall of the target liquid delivery pipeline will increase with the transportation of the liquid, the detection result of the flow sensor will gradually begin to fail from being relatively accurate. Therefore, when the detection result of the flow sensor is relatively accurate, the preset flow curve can be adjusted through step S120; when the detection result of the flow sensor fails, the subsequent blockage time can be judged by adjusting the flow curve, thereby achieving the effect of accurately identifying the estimated blockage time of the target liquid delivery pipeline.

[0033] S120, at the flow correction time, adjusting the preset flow curve based on the pipeline flow to obtain an adjusted flow curve.

[0034] The preset flow curve reflects the change of the flow of the target liquid delivery pipeline over time, and the preset flow curve may be determined in advance based on the historical flow data of the target liquid delivery pipeline or the flow data of other pipelines.

[0035] Specifically, the preset flow curve can reflect the flow change of the target liquid delivery pipeline from the start time, but the flow is different from the actual flow, so the preset flow curve can be adjusted based on the pipeline flow at the flow correction time, and the specific adjustment method includes but is not limited to curve translation, scaling, distortion, etc. The adjusted curve is determined as the adjusted flow curve.

[0036] Exemplarily, when continuously acquiring pipeline flow, if it is determined that the flow correction moment has been reached, the preset flow curve is shifted according to the pipeline flow at the flow correction moment to obtain an adjusted flow curve, so that the adjusted flow curve is more consistent with the actual measured pipeline flow; if the flow correction moment is reached again, the adjusted flow curve obtained by the last adjustment is shifted according to the pipeline flow at the flow correction moment to obtain a new adjusted flow curve, so that the adjusted flow curve is more consistent with the latest pipeline flow, until the time when the pipeline flow has expired is reached, and S130 is executed.

[0037] S130: If it is determined that the pipeline flow detected by the flow sensor has failed, an estimated blockage time of the target liquid delivery pipeline is determined based on the adjusted flow curve.

[0038] Among them, the failure of the pipeline flow reflects that the pipeline flow can no longer reflect the actual flow in the target liquid delivery pipeline. In one case, if the pipeline flow detected by the flow sensor becomes 0, it is determined that the pipeline flow at that moment has failed; in another case, if the pipeline flow detected by the flow sensor is reduced to the blockage flow threshold, it is determined that the pipeline flow at that moment has failed; in yet another case, if the pipeline flow detected by the flow sensor continues to decrease, and the decrease rate is greater than the standard value, it is determined that the pipeline flow at that moment has failed.

[0039] Specifically, in the process of continuously receiving the pipeline flow detected by the flow sensor, if it is determined that the pipeline flow detected by the flow sensor has failed, the time when the flow drops to the blockage flow threshold is determined based on the adjusted flow curve, and the time is determined as the estimated blockage time of the target liquid delivery pipeline.

[0040] In an embodiment of the present application, optionally, determining an estimated blockage time of the target liquid delivery pipeline based on the adjusted flow curve includes: determining the time corresponding to the blockage flow threshold in the adjusted flow curve as the estimated blockage time.

[0041] In an embodiment of the present application, optionally, the method further includes: obtaining the latest adjusted flow curve of each stage, fitting each curve, and obtaining a historical flow curve corresponding to the target liquid delivery pipeline, so that when subsequently determining the preset flow curves of other liquid delivery pipelines, the determination is made according to the historical flow curves corresponding to the target liquid delivery pipeline.

[0042] The technical solution of the embodiment of the present application includes: continuously obtaining the pipeline flow rate obtained by the flow sensor detecting the target liquid delivery pipeline; at the flow correction moment, adjusting the preset flow curve based on the pipeline flow rate to obtain an adjusted flow curve; the preset flow curve reflects the change of the flow rate of the target liquid delivery pipeline over time; if it is determined that the pipeline flow rate detected by the flow sensor has failed, then determining the estimated blockage time of the target liquid delivery pipeline based on the adjusted flow curve. This technical solution adjusts the preset flow curve so that the obtained adjusted flow curve is closer to the pipeline flow, and then after the pipeline flow fails, the estimated blockage time of the target liquid delivery pipeline can be accurately determined based on the adjusted flow curve.

[0043] Embodiment 2

[0044] Figure 2This is a flow chart of a method for determining the blockage time of a liquid delivery pipeline provided in Example 2 of the present application. The embodiment of the present application is optimized based on the above embodiment.

[0045] like Figure 2 As shown, the method of the embodiment of the present application specifically includes the following steps:

[0046] S210, continuously acquiring the pipeline flow rate obtained by the flow sensor detecting the target liquid delivery pipeline.

[0047] S220: If it is determined that the pipeline flow curve and the preset flow curve meet the curve deviation condition, the current time is determined as the flow correction time.

[0048] Specifically, under normal circumstances (for example, in the early and middle stages of transporting chemical liquids in the target liquid delivery pipeline), the pipeline flow collected by the flow sensor is relatively accurate, and it can identify in real time whether the pipeline flow curve and the preset flow curve meet the curve deviation condition. If so, it means that the gap between the preset flow curve and the pipeline flow is too large, and the preset flow curve should be adjusted, that is, the current moment is determined as the flow correction moment.

[0049] In an embodiment of the present application, optionally, if it is determined that the pipeline flow curve and the preset flow curve meet the curve deviation condition, the current time is determined as the flow correction moment, including: if the flow difference between the pipeline flow value and the preset flow value is greater than the first flow threshold, the current time is determined as the flow correction moment; the pipeline flow value is the value in the pipeline flow curve corresponding to the current time, and the preset flow value is the value in the preset flow curve corresponding to the current time.

[0050] Among them, the first flow threshold can be determined according to actual conditions, and the embodiment of the present application does not limit this.

[0051] Specifically, the numerical value corresponding to the current time in the preset flow curve is determined as the preset flow value; the pipeline flow of the flow sensor obtained at the current time is determined as the pipeline flow value, and the flow difference between the preset flow value and the pipeline flow value is calculated. If the flow difference is greater than the first flow threshold, it indicates that the pipeline flow curve deviates greatly from the preset flow curve, and the curve deviation condition has been met, and the current time is determined as the flow correction moment.

[0052] The present scheme is configured in such a way that the degree of deviation between the latest pipeline flow value and the preset flow value in the pipeline flow curve can be determined in real time, and then the flow correction moment can be determined in time when the flow difference is greater than the first flow threshold value to adjust the preset flow curve, so that the preset flow curve (i.e., the adjusted flow curve) is always close to the latest actual pipeline flow.

[0053] In an embodiment of the present application, optionally, if it is determined that the pipeline flow curve and the preset flow curve meet the curve deviation condition, the current time is determined as the flow correction moment, including: if the flow difference between the pipeline flow value and the preset flow value is greater than the second flow threshold, and the slope difference between the pipeline flow curve at the current time and the preset flow curve is greater than the preset slope difference, the current time is determined as the flow correction moment.

[0054] The second flow threshold is smaller than the first flow threshold.

[0055] Specifically, if the flow difference between the pipeline flow value and the preset flow value is greater than the second flow threshold and less than the first flow threshold, it means that the real-time pipeline flow and the preset pipeline curve have a certain offset, but the offset is not large. In this case, if the slope difference between the pipeline flow curve at the current time and the preset flow curve is greater than the preset slope difference, it means that the pipeline flow curve and the preset flow curve have a trend of increasing deviation. In this case, the current time can be determined as the flow correction moment to perform flow correction in advance.

[0056] In an embodiment of the present application, optionally, the process of determining the flow correction time includes: obtaining a pre-calibrated correction interval time; starting from the first use of the target liquid delivery pipeline, each time a correction interval time has passed, determining the current time as the flow correction time.

[0057] Specifically, the correction interval time may be preset, and the current time may be determined as the flow correction moment every time the correction interval time elapses, so as to realize continuous correction of the preset flow curve.

[0058] S230, at the flow correction time, determining the curve located at the flow correction time and after the flow correction time in the preset flow curve as the curve to be moved.

[0059] Specifically, if the flow correction time is reached, the curve located at the flow correction time and after the flow correction time in the preset flow curve is determined as the curve to be moved, so that the curve to be moved is moved in subsequent steps.

[0060] S240, moving the curve to be moved in the direction of the pipeline flow curve to obtain an adjusted flow curve.

[0061] Specifically, the moving curve is moved. When moving, since the horizontal axis is time and the vertical axis is flow, the moving curve can be translated up and down so that the value of the current moment in the obtained adjusted flow curve is equal to the pipeline flow value.

[0062] In an embodiment of the present application, optionally, the curve to be moved is moved in the direction of the pipeline flow curve to obtain an adjusted flow curve, including: determining a first flow value corresponding to the flow correction moment in the pipeline flow curve, and determining a second flow value corresponding to the flow correction moment in the curve to be moved; in a plane rectangular coordinate system, determining a target moving direction and a target moving distance from the second flow value to the first flow value; in a plane rectangular coordinate system, translating the curve to be moved based on the target moving direction and the target moving distance to obtain an adjusted flow curve.

[0063] Specifically, a plane rectangular coordinate system is established, and a pipeline flow curve is generated based on the acquired pipeline flow. The numerical value of the pipeline flow curve corresponding to the flow correction moment is determined as the first flow value, and the numerical value of the curve to be moved corresponding to the flow correction moment is determined as the second flow value. In the plane rectangular coordinate system, the target moving direction and target moving distance required to move from the second flow value to the first flow value are calculated, and the curve to be moved is translated according to the target moving direction and target moving distance to obtain an adjusted flow curve.

[0064] Furthermore, if the flow correction time is reached again, the adjustment operation is performed again on the current adjustment flow curve. The adjustment method can be the same as the preset flow curve to obtain a new adjustment flow curve until it is determined that the pipeline flow detected by the flow sensor has failed.

[0065] S250: If it is determined that the pipeline flow detected by the flow sensor has failed, an estimated blockage time of the target liquid delivery pipeline is determined based on the adjusted flow curve.

[0066] In an embodiment of the present application, optionally, if it is determined that the pipeline flow detected by the flow sensor has failed, the estimated blockage time of the target liquid delivery pipeline is determined based on the adjusted flow curve, including: if it is determined that the pipeline flow detected by the flow sensor has failed, and the interval time between the failure time and the last flow correction time is greater than the failure time of the flow sensor, the estimated blockage time of the target liquid delivery pipeline is determined based on the latest adjusted flow curve; otherwise, the estimated blockage time of the target liquid delivery pipeline is determined based on the adjusted flow curve obtained by the last curve adjustment.

[0067] Specifically, since the data of the flow sensor are not of reference within the failure duration, if it is determined that the pipeline flow detected by the flow sensor has failed, and the interval between the failure time and the last flow correction time is greater than the failure duration of the flow sensor, it means that the latest adjusted flow curve is adjusted according to the actual pipeline flow, and the estimated blockage time of the target liquid delivery pipeline is determined based on the latest adjusted flow curve; otherwise, it means that the latest adjusted flow curve is adjusted according to the failed pipeline flow and has no reference value, and the estimated blockage time of the target liquid delivery pipeline can be determined based on the adjusted flow curve before the latest adjusted flow curve (i.e., the second to last adjusted flow curve).

[0068] In an embodiment of the present application, optionally, if it is determined that the pipeline flow detected by the flow sensor has failed, the possible blockage time corresponding to the blockage flow threshold is determined based on the adjusted flow curve. If it is determined that the current time has reached the possible blockage time, the liquid level change information of the liquid storage device is obtained. The liquid storage device is a device for storing liquid connected to the target liquid delivery pipeline (due to the complex environment inside the target liquid delivery pipeline, the flow rate cannot be directly measured, and it can be indirectly inferred through the information of the outflowing liquid). The flow rate of the target liquid delivery pipeline is calculated according to the liquid change information. If the flow rate is greater than the blockage flow threshold, the adjusted flow curve is adjusted again based on the flow rate, so that the time corresponding to the blockage flow threshold is used as the estimated blockage time according to the final adjusted flow curve.

[0069] The technical solution of the embodiment of the present application determines a flow correction time suitable for curve adjustment according to the degree of deviation between the pipeline flow curve and the preset flow curve, and then adjusts the preset flow curve at the flow correction time, so that the obtained adjusted flow curve is closer to the actual flow of the target liquid delivery pipeline. After the pipeline flow collected by the flow sensor fails, a more accurate blockage time of the target liquid delivery pipeline can be determined based on the adjusted flow curve, providing accurate data for assembly line production and avoiding the situation where the generation plan is disrupted due to sudden blockage of the pipeline.
