Description
Technical Field
[0001] The present application relates to the technical field of flow monitoring, and in particular to a pipeline flow monitoring method, an electromagnetic flowmeter, and a system. Background Art
[0002] An electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow rate of a conductive fluid based on the electromotive force induced when the fluid passes through an applied magnetic field. Electromagnetic flowmeters are widely used in pipeline flow monitoring systems, making it easier to monitor pipeline flow.
[0003] However, in the current process of monitoring pipeline flow, all monitoring pipelines are usually monitored simultaneously. Since the flow rates of different pipelines may be different, the monitoring results of pipeline flow may have large errors during the process of monitoring pipelines at the same time. Summary of the Invention
[0004] In order to reduce errors generated during pipeline flow monitoring, the present application provides a pipeline flow monitoring method, an electromagnetic flowmeter, and a system.
[0005] In a first aspect, the present application provides a method for monitoring pipeline flow, which adopts the following technical solution:
[0006] A method for monitoring pipeline flow, comprising:
[0007] Obtaining a monitoring area and a current time point of the pipeline, wherein the monitoring area includes a living area and an entertainment area;
[0008] Determining whether the current time point matches a preset first time period;
[0009] If the current time point matches the first time period, obtaining an entertainment area monitoring instruction;
[0010] monitoring the pipelines in the entertainment area based on the entertainment area monitoring instruction;
[0011] If the current time point does not match the first time period, determining whether the current time point matches a preset second time period;
[0012] If the current time point matches the second time period, obtaining a living area monitoring instruction;
[0013] monitoring the pipelines in the living area based on the living area monitoring instruction;
[0014] If the current time point does not match the second time period, obtaining the instruction to be monitored;
[0015] Based on the instruction to be monitored, alarm monitoring of the pipeline in the living area is stopped.
[0016] By employing the above technical solution, the current time point is matched with the first and second time periods to determine whether to monitor the pipelines in the entertainment area, the pipelines in the living area, or whether to not monitor the monitoring area. This approach allows flow monitoring in different areas at different time points, ensuring that the pipeline flow monitoring time is more consistent with the flow conditions in the corresponding area, thereby reducing errors in the pipeline flow monitoring process.
[0017] As an option, it also includes:
[0018] Acquire a monitoring instruction type, where the monitoring instruction type includes the entertainment area monitoring instruction and the living area monitoring instruction;
[0019] When it is determined that the monitoring instruction type is the entertainment zone monitoring instruction, obtaining the pipeline monitoring flow of the entertainment zone as the entertainment zone flow;
[0020] Determining whether the flow rate of the entertainment area is greater than a preset first flow rate;
[0021] If the entertainment area traffic is greater than the first traffic, obtaining entertainment area traffic leakage alarm information;
[0022] When it is determined that the monitoring instruction type is the living area monitoring instruction, obtaining the pipeline monitoring flow of the living area as the living area flow;
[0023] Determining whether the flow rate of the living area is greater than a preset second flow rate;
[0024] If the living area traffic is greater than the second traffic, living area traffic leakage alarm information is obtained.
[0025] By adopting the above technical solution, the flow rate of the corresponding area is determined according to different monitoring instruction types, and then the corresponding alarm information is obtained according to the relationship between the flow rate of the entertainment area and the first flow rate, or according to the relationship between the flow rate of the living area and the second flow rate, so as to remind the pipeline leakage at the corresponding location.
[0026] Preferably, after monitoring the pipelines in the living area based on the living area monitoring instruction, the method further includes:

[0030] obtaining a current water consumption-discharge ratio based on the current water consumption and the current discharge volume;
[0031] Determining whether the current water use-drainage ratio matches the average water use-drainage ratio;
[0032] If there is no match, pipeline flow abnormality information is generated and output.
[0033] By adopting the above technical solution, pipeline anomalies are determined by determining whether the average water-to-drainage ratio matches the current water-to-drainage ratio. If they do not match, pipeline flow anomaly information is generated and output. Using this ratio to determine whether a pipeline flow anomaly is present improves the accuracy of the determination.
[0034] Preferably, after generating and outputting the pipeline flow abnormality information, the method includes:
[0035] Acquire historical water consumption during the preset time period based on the historical water consumption data;
[0036] Acquiring a historical drainage volume within a preset time period based on the historical drainage data;
[0037] Determining whether the current water consumption matches the historical water consumption;
[0038] If the current water consumption matches the historical water consumption, determining that the pipeline flow abnormality information is a drainage pipeline abnormality;
[0039] If the current water consumption does not match the historical water consumption, determining whether the current drainage volume matches the historical drainage volume;
[0040] If the current drainage volume matches the historical drainage volume, determining that the pipeline flow abnormality information is an abnormality in the water inlet pipeline;
[0041] If the current drainage volume does not match the historical drainage volume, it is determined that the pipeline flow abnormality information is an abnormality of the inlet and outlet water pipelines.
[0042] By adopting the above technical solution, if the current water consumption-drainage ratio is greater than the average water consumption-drainage ratio, the matching relationship between the current water consumption and the historical water consumption, and the matching relationship between the current drainage and the historical drainage, can be used to determine whether the pipeline flow abnormality is due to the drainage pipeline abnormality, the water inlet pipeline abnormality, or the inlet and outlet pipeline abnormality. This can further determine the cause of the pipeline abnormality.
[0043] Preferably, after determining that the abnormal pipeline flow information is a drainage pipeline abnormality, the method further includes:
[0044] Determining the magnitude of the current water discharge and the historical water discharge;
[0045] When the current drainage volume is greater than the historical drainage volume, it is confirmed that the drainage pipe abnormality is a drainage pipe leakage;
[0046] When the current drainage volume is less than the historical drainage volume, it is confirmed that the drainage pipe abnormality is a blockage of the drainage pipe.
[0047] By adopting the above technical solution, the drainage pipe abnormality is determined to be a blockage or leakage according to the current drainage volume and the historical drainage volume, and the specific cause of the pipeline abnormality can be further determined.
[0048] Preferably, after determining that the pipeline flow abnormality information is an abnormality in the water inlet pipeline, the method further includes:
[0049] Determine the current water inflow and the historical water inflow;
[0050] When the current water inflow is greater than the historical water inflow, it is confirmed that the abnormality of the water inflow pipeline is a water inflow pipeline leakage;
[0051] When the current water inflow is less than the historical water inflow, it is confirmed that the abnormality of the water inlet pipeline is a blockage of the water inlet pipeline.
[0052] By adopting the above technical solution, the water inlet pipe abnormality is determined to be a blockage or leakage of the water inlet pipe according to the current water inlet volume and the historical water inlet volume, and the specific cause of the pipeline abnormality can be further determined.
[0053] Preferably, after determining that the pipeline flow abnormality information is an abnormality of the inlet and outlet pipes, the method further includes:
[0054] Obtain the pressure value of the water inlet pipe and the pressure value of the drainage pipe;
[0055] Determining the magnitude relationship between the water inlet pipe pressure value and the water inlet pressure threshold, and determining the magnitude relationship between the drainage pipe pressure value and the drainage pressure threshold;
[0056] If the water inlet pipe pressure value is greater than the water inlet pressure threshold, and the drainage pipe pressure value is greater than the drainage pressure threshold, it is determined that the abnormality of the inlet and outlet pipes is caused by blockage of both the water inlet pipe and the drainage pipe;
[0057] If the water inlet pipe pressure value is greater than the water inlet pressure threshold, and the drainage pipe pressure value is less than the drainage pressure threshold, it is determined that the abnormality of the inlet and outlet pipes is a blockage of the water inlet pipe and a leakage of the drainage pipe;
[0058] If the water inlet pipe pressure value is less than the water inlet pressure threshold, and the drainage pipe pressure value is greater than the drainage pressure threshold, it is determined that the abnormality of the inlet and outlet pipes is a leakage of the water inlet pipe and a blockage of the drainage pipe;
[0059] If the water inlet pipe pressure value is less than the water inlet pressure threshold, and the drainage pipe pressure value is less than the drainage pressure threshold, it is determined that the abnormality of the inlet and outlet pipes is leakage of both the water inlet pipe and the drainage pipe.
[0060] By adopting the above technical solution, the relationship between the water inlet pipe pressure value and the water inlet pressure threshold, as well as the relationship between the drainage pipe pressure value and the drainage pressure threshold, and then determining the specific situation of the abnormality of the water inlet and outlet pipes, the accuracy of the judgment can be further improved.
[0061] As an option, it also includes:
[0062] Obtaining monitoring results of the monitoring area;

[0069] By adopting the above technical solution, the display is separated from the flow meter body, and the flow meter body and flow sensor are fixed to the measuring conduit. This can reduce the possibility of measurement data being interfered with and causing inaccurate data measurement, thereby improving the accuracy of the obtained monitoring data. At the same time, the memory can store information, and the processor can retrieve information and issue control instructions, ensuring the orderly execution of the program and achieving the effect of the above solution.

[0088] The following is combined with Figures 1 to 9 This application is described in further detail.
[0089] The present application discloses an electromagnetic flowmeter, referring to Figure 1 , comprising: a measuring conduit 1, a flow sensor 2 and a flow meter body 3 provided on the measuring conduit 1, and a display 4 communicatively connected to the flow meter body 3, the flow meter body 3 being electrically connected to the flow sensor 2, and the flow meter body 3 including a memory and a processor;
[0090] The memory stores a computer program that can be run on the processor. When the processor runs the computer program, it can execute the steps of the pipeline flow monitoring method.
[0091] The flowmeter body 3 and the flow sensor 2 are electrically connected via a shielded wire, and both the flowmeter body 3 and the flow sensor 2 are fixed to the measuring conduit 1. This connection method can reduce the length of the connecting wire between the flowmeter body 3 and the flow sensor 2, thereby reducing the inter-wire capacitance and, in turn, the signal response speed, thereby increasing the measurement frequency of the electromagnetic flowmeter. By reducing the length of the shielded wire, the influence of the ambient magnetic field on the shielded wire signal can be reduced, thereby improving the accuracy of the measurement data transmitted from the flow sensor 2 to the flowmeter body 3.
[0092] The flow meter body 3 is communicatively connected to the display 4. The connection can be wired via a communication line, such as an RS485 line, or wirelessly via Bluetooth or other wireless connection methods. With this connection method, when the user uses the electromagnetic flow meter for flow monitoring, the display 4 can be installed in another location to facilitate viewing of the monitored data. At the same time, when the data processed by the flow meter body 3 is transmitted to the display 4, it is less affected by environmental factors and the accuracy of the transmitted data is higher.
[0093] Of course, in one embodiment of the present application, the display 4 can be connected to multiple flow meter bodies 3. The display 4 is a touch screen, and the user can select and view the monitoring data monitored by different flow meter bodies 3 by clicking on the touch screen. Of course, the display 4 may also be a combination of non-touch screen and buttons.
[0094] The present application also discloses a pipeline flow monitoring system. Figure 2 The pipeline flow monitoring system includes several of the above-mentioned electromagnetic flow meters and a cloud server 5 that is communicatively connected to the electromagnetic flow meters.
[0095] The electromagnetic flowmeter can send the monitoring data of the pipeline to the cloud server 5, so that the data can be stored in the cloud. At the same time, the user can also operate on the electromagnetic flowmeter to view the monitoring data measured by different electromagnetic flowmeters from the cloud server 5.
[0096] The embodiment of the present application also discloses a method for monitoring pipeline flow.
[0097] Reference Figure 3 , pipeline flow monitoring methods include:
[0098] S1. Obtain the monitoring area and current time point of the pipeline;
[0099] S2. Determine whether the current time point matches the preset first time period;
[0100] S3. If the current time point matches the first time period, obtain the entertainment area monitoring instruction;
[0101] S4. Based on the entertainment area monitoring instructions to monitor the pipeline in the entertainment area;
[0102] S5. If the current time point does not match the first time period, it is determined whether the current time point matches the preset second time period;
[0103] S6. If the current time point matches the second time period, obtain the living area monitoring instruction;
[0104] S7. Based on the living area monitoring instructions to monitor the pipeline in the living area;
[0105] S8. If the current time point does not match the second time period, obtain the instruction to be monitored;
[0106] S9. Stop alarm monitoring of the pipelines in the living area based on the instruction to be monitored.
[0107] Peak and off-peak water usage vary across different areas and time periods. For residential areas, water usage is higher during the day and lower at night when residents are resting, so the off-peak period for these areas is at night. Meanwhile, for recreational areas, the afternoon and evening hours are more crowded, while the daytime hours are relatively less frequent, so the off-peak period for recreational areas is in the morning.
[0108] At this time, the pipeline flow in the living area and the entertainment area is measured at the same time. If the measurement is carried out during the low-peak period of water consumption in the living area, the data monitored in the entertainment area will be inaccurate. Similarly, if the measurement is carried out during the low-peak period of water consumption in the entertainment area, the data monitored in the living area will be inaccurate.
[0109] Therefore, it is necessary to measure the flow rates of pipelines in different areas separately. The current time point can be obtained by recording it using a timer or a timing system. The monitoring area of the pipeline is also obtained, which includes the living area and the entertainment area. This monitoring area can be obtained using a position sensor.
[0110] Then determine whether the current time point matches the preset first time period, where the first time period is the low-peak period of water consumption in the entertainment area. The acquisition method can be through historical measurement data, and then the start time and end time of the historical lowest peak of water consumption in the entertainment area are obtained, and then the start time and end time and the time between the two are used as the first time period.
[0111] A determination is made as to whether the current time point matches the first time period, i.e., whether the current time point falls within the first time period. If so, a match is confirmed; otherwise, a mismatch is confirmed. If a match is confirmed, the flow rate in the entertainment area pipeline can be monitored. Therefore, an entertainment area monitoring instruction is obtained, and the corresponding flow sensor is energized according to the entertainment area monitoring instruction, thereby enabling monitoring of the flow rate in the entertainment area pipeline.
[0112] If there is no match, it proves that it is not suitable to monitor the entertainment area at this time. Then, it is determined whether the current time point matches the preset second time period, where the second time period is the low-peak period of water consumption in the living area, and the acquisition method is the same as that of the first time period.
[0113] If the current time point matches the second time period, a living area monitoring instruction is obtained, and then the flow sensor in the living area is powered on according to the living area monitoring instruction, thereby monitoring the pipeline flow in the living area.
[0114] If the current time point does not match the second time period, it proves that it is neither the monitoring time period of the living area nor the monitoring time period of the entertainment area. At this time, the monitoring instruction is obtained, and the flow sensors for flow abnormality monitoring in the living area and the entertainment area are controlled to be powered off through the monitoring instruction, that is, the alarm monitoring of the living area and the entertainment area is stopped, thereby saving energy.
[0115] It should be noted that the flow sensors that monitor the normal flow usage in the living and entertainment areas are powered on and working normally. This improves the accuracy of monitoring the flow in pipelines in different areas and at different times, and reduces the possibility of flow monitoring errors.
[0116] Reference Figure 4 Furthermore, in order to improve the accuracy of determining whether a pipeline flow leak occurs, in another embodiment, the pipeline flow monitoring method further includes:
[0117] S11. Get monitoring instruction type;
[0118] S12. When it is determined that the monitoring instruction type is the entertainment area monitoring instruction, the pipeline monitoring flow of the entertainment area is obtained as the entertainment area flow;
[0119] S13 determines whether the flow rate of the entertainment area is greater than the preset first flow rate;
[0120] S14. If the entertainment area traffic is greater than the first traffic, then obtain the entertainment area traffic leakage alarm information;
[0121] S15. When it is determined that the monitoring instruction type is a living area monitoring instruction, obtain the pipeline monitoring flow of the living area as the living area flow;
[0122] S16. Determine whether the flow rate in the living area is greater than the preset second flow rate;
[0123] S17. If the living area traffic is greater than the second traffic, obtain living area traffic leakage alarm information.
[0124] Specifically, in the process of monitoring the living area or the entertainment area through the monitoring instruction, the monitoring instruction type is obtained, wherein the monitoring instruction type includes the entertainment area monitoring instruction and the living area monitoring instruction.
[0125] When the monitoring instruction type is determined to be an entertainment area monitoring instruction, the pipeline monitoring flow of the entertainment area is obtained as the entertainment area flow by measuring the pipeline flow of the entertainment area pipeline within a preset time period through an electromagnetic flowmeter.
[0126] Then, a determination is made as to whether the flow rate in the entertainment area is greater than a preset first flow rate. The first flow rate is the maximum flow rate achieved within a preset time period based on historical monitoring data. Furthermore, the first flow rate is a range of values, including an upper limit and a lower limit. Determining whether the flow rate in the entertainment area is greater than the first flow rate refers to determining whether the flow rate in the entertainment area is greater than the upper limit of the first flow rate.
[0127] If the flow rate in the entertainment area is greater than the first flow rate, it indicates that a leak may occur in the entertainment pipeline. Therefore, an entertainment area flow leakage alarm is obtained and sent to the corresponding display for display, thereby alerting relevant staff. If the flow rate in the entertainment area is not greater than the first flow rate, no action is taken.
[0128] If the monitoring instruction type is determined to be a living area monitoring instruction, the pipeline monitoring flow rate in the living area is obtained as the living area flow rate in the same manner as the entertainment area flow rate. A determination is then made as to whether the living area flow rate is greater than a preset second flow rate, where the second flow rate is the maximum flow rate achieved within a preset time period based on historical monitoring data. The second flow rate is a range of values, including an upper limit and a lower limit. Determining whether the living area flow rate is greater than the second flow rate is based on whether the living area flow rate is greater than the upper limit of the second flow rate.
[0129] If the flow rate in the living area exceeds the second flow rate, it indicates a possible leak in the living area pipes. Therefore, a living area flow leak alarm is generated and sent to the corresponding display for display, alerting relevant staff. If the flow rate in the living area does not exceed the second flow rate, no action is taken. This method allows for timely determination of leaks in the pipes in the living or entertainment areas.
[0130] Reference Figure 5 In order to improve the accuracy of monitoring abnormal pipeline flow, in another embodiment, after monitoring the pipelines in the living area based on the living area monitoring instruction, the method further includes:
[0131] S21. Obtain historical water consumption data and historical drainage data for pipeline monitoring;
[0132] S22. Obtaining an average water use-discharge ratio based on historical water use data and historical discharge data;
[0133] S23. Get the current water consumption and current drainage volume in the preset time;
[0134] S24. Obtaining a current water consumption-discharge ratio based on the current water consumption and the current discharge;
[0135] S25. Determine whether the current water use-drainage ratio matches the average water use-drainage ratio;
[0136] If there is no match, generate and output pipeline flow abnormality information.
[0137] Specifically, after monitoring the pipes in the living area, or of course, the pipes in the entertainment area, historical water usage data and historical drainage data of the monitored pipes are obtained, wherein the historical water usage data and historical drainage data are all pre-stored data.
[0138] Then, the average water use-drainage ratio is obtained based on the historical water use data and historical drainage data. The method of obtaining it is to obtain multiple historical water use and historical drainage ratios within the same time period, and then calculate the average value of all the obtained ratios. The obtained value is the average water use-drainage ratio.
[0139] Then, the current water consumption and current drainage volume within the preset time are obtained. The preset time can be set according to actual conditions, and the current water consumption and current drainage volume are obtained by measuring the abnormal pipeline flow with an electromagnetic flowmeter.
[0140] The current water consumption and drainage volume are used to calculate the current water-to-drainage ratio. This is calculated by dividing the current water consumption by the current drainage volume. The current water-to-drainage ratio is then compared to the average water-to-drainage ratio, which has an upper and lower error limit.
[0141] If the current water-to-drainage ratio falls between the upper and lower error limits, it matches the average water-to-drainage ratio; otherwise, it does not. If the two match, there is no abnormality in the pipeline. If they do not, a pipeline flow anomaly message is generated and displayed on the display, alerting personnel and allowing them to promptly inspect and repair the abnormal pipeline. This ensures the accuracy of pipeline flow anomaly monitoring, improves pipeline safety, and conserves energy.
[0142] Reference Figure 6 In order to further determine the specific situation of the pipeline abnormality, in another embodiment, after generating and outputting the pipeline flow abnormality information, the following steps are included:
[0143] S31. Obtain historical water consumption over a preset period based on historical water consumption data;
[0144] S32. Obtain historical drainage volume over a preset period of time based on historical drainage data;
[0145] S33. Determine whether the current water consumption matches the historical water consumption;
[0146] S34. If the current water consumption matches the historical water consumption, the abnormal pipeline flow information is determined to be a drainage pipeline abnormality;
[0147] S35. If the current water consumption does not match the historical water consumption, determine whether the current drainage volume matches the historical drainage volume;
[0148] S36. If the current drainage volume matches the historical drainage volume, the abnormal pipeline flow information is determined to be an abnormality in the water inlet pipeline;
[0149] S37. If the current drainage volume does not match the historical drainage volume, it is determined that the pipeline flow abnormality information is an abnormality of the inlet and outlet pipes.
[0150] Specifically, after the pipeline flow abnormality information is generated and output, the historical water consumption within the preset time period is obtained based on the historical water consumption data, and then the historical drainage volume within the preset time period is obtained based on the historical drainage data. Of course, the obtained historical water consumption and historical drainage volume are set with upper and lower limits.
[0151] Then, the system determines whether the current water consumption matches the historical water consumption, i.e., whether the current water consumption falls between the upper and lower limits of the historical water consumption. If so, the water consumption matches; otherwise, the water consumption does not match. If the current water consumption matches the historical water consumption, and the current water consumption-discharge ratio is greater than the average water consumption-discharge ratio, then the flow rate through the drainage pipe has changed within the preset time period, indicating that an abnormality has occurred in the drainage pipe. This indicates that the pipe flow abnormality is not caused by an abnormality in the inlet pipe.
[0152] If the current water consumption does not match the historical water consumption, the current drainage volume is determined to match the historical drainage volume. This determination is made in the same way as the determination of whether the current water consumption matches the historical drainage volume. If the current drainage volume matches the historical drainage volume, the drainage pipeline is normal, and the abnormal flow rate is determined to be abnormal, not the inlet pipeline.
[0153] If the current discharge volume does not match the historical discharge volume, it indicates that not only the water inlet pipe is abnormal, but also the drainage pipe is abnormal. Therefore, the pipeline flow abnormality information is determined to be an abnormality in the water inlet and outlet pipes. This method can further determine whether the pipeline abnormality is in the water inlet pipe or the drainage pipe, further improving the accuracy of the judgment.
[0154] Reference Figure 7 In order to further determine the specific abnormality of the drainage pipe, in another embodiment, after determining that the pipeline flow abnormality information is a drainage pipe abnormality, the method further includes:
[0155] S41. Determine the current displacement and historical displacement;
[0156] S42. If the current drainage volume is greater than the historical drainage volume, the drainage pipe abnormality is indeed a leakage;
[0157] S43. If the current drainage volume is less than the historical drainage volume, the drainage pipe abnormality is indeed blocked.
[0158] Specifically, after determining that the flow anomaly is a drainage pipe anomaly, the current drainage volume is compared to the historical drainage volume, where both the current drainage volume and the historical drainage volume are from the same time period. If the current drainage volume is greater than the historical drainage volume, it indicates that the drainage pipe drainage volume has suddenly increased within the same time period, indicating that the drainage pipe anomaly is leaking.
[0159] If the current drainage volume is less than the historical drainage volume, it indicates that the drainage pipe's drainage volume has suddenly decreased within the same period of time, which indicates that the drainage pipe abnormality is a blockage. Therefore, by comparing the current drainage volume with the historical drainage volume, the specific cause of the drainage pipe abnormality can be determined, which can further improve the accuracy of the judgment.
[0160] Reference Figure 8 In order to further determine the specific abnormality of the water inlet pipe, in another embodiment, after determining that the pipeline flow abnormality information is an abnormality of the water inlet pipe, the method further includes:
[0161] S51. Determine the current water inflow and the historical water inflow;
[0162] S52. If the current water inflow is greater than the historical water inflow, the abnormality in the water inflow pipeline is indeed a leak;
[0163] S53. If the current water inflow is less than the historical water inflow, the abnormality in the water inflow pipe is indeed due to blockage.
[0164] Specifically, after determining that the flow anomaly is due to an inlet pipe anomaly, the current water inflow and the historical water inflow are compared. Both the current and historical water inflows are taken from the same time period. If the current water inflow is greater than the historical water inflow, it indicates that the water inflow to the water inlet pipe suddenly increased within the same time period, indicating that the anomaly is a leak.
[0165] If the current water inflow is less than the historical water inflow, it indicates that the water inflow into the water pipe has suddenly decreased within the same period of time, which indicates that the abnormality in the water pipe is due to blockage. Therefore, by comparing the current water inflow with the historical water inflow, the specific cause of the abnormality in the water pipe can be determined, which can further improve the accuracy of the judgment.
[0166] Reference Figure 9When it is determined that both the water inlet pipe and the drainage pipe are abnormal, in order to determine the specific abnormal situation, in another embodiment, after determining that the pipeline flow abnormality information is abnormal in the water inlet and outlet pipes, the following is further included:
[0167] S61. Obtain the water inlet pipe pressure value and the drainage pipe pressure value;
[0168] S62. Determine the relationship between the water inlet pressure value and the water inlet pressure threshold, and determine the relationship between the drainage pipe pressure value and the drainage pressure threshold;
[0169] S63. If the water inlet pipe pressure value is greater than the water inlet pressure threshold, and the drainage pipe pressure value is greater than the drainage pressure threshold, it is determined that the water inlet and outlet pipe abnormality is simultaneously blocked;
[0170] S64. If the water inlet pipe pressure value is greater than the water inlet pressure threshold, and the drainage pipe pressure value is less than the drainage pressure threshold, it is determined that the water inlet and outlet pipe abnormalities are blocked in the water inlet pipe and leaking in the drainage pipe;
[0171] S65. If the water inlet pipe pressure value is less than the water inlet pressure threshold, and the drainage pipe pressure value is greater than the drainage pressure threshold, it is determined that the water inlet and outlet pipe abnormalities are leaking and the drainage pipe is blocked;
[0172] S66. If the water inlet pipe pressure value is less than the water inlet pressure threshold, and the drainage pipe pressure value is less than the drainage pressure threshold, it is determined that the abnormality of the inlet and outlet pipes is caused by leakage of both the water inlet pipe and the drainage pipe.
[0173] Specifically, after determining that the abnormal pipeline flow information is an inlet or outlet pipe abnormality, the inlet pipe pressure value and the drainage pipe pressure value are obtained. The acquisition method can be used to measure and obtain them using a pressure sensor. Then, the relationship between the inlet pipe pressure value and the inlet pressure threshold is determined, and the relationship between the drainage pipe pressure value and the drainage pressure threshold is also determined. The inlet pressure threshold and the drainage pressure threshold can both be set according to actual conditions.
[0174] If the water inlet pipe pressure value is greater than the water inlet pressure threshold, it proves that the water inlet pipe pressure has increased while the water supply pump is supplying water at the same pressure, indicating that the water inlet pipe is blocked. If the drainage pipe pressure value is greater than the drainage pressure threshold, it proves that the drainage pipe pressure has also increased while the drainage pump is draining water at the same pressure, indicating that the drainage pipe is also blocked. Therefore, the abnormality in the water inlet and outlet pipes is determined to be caused by simultaneous blockage of the water inlet and drainage pipes.
[0175] If the inlet pipe pressure value is greater than the inlet pressure threshold, it indicates that the pressure in the inlet pipe has increased while the water supply pump is supplying water at the same pressure, indicating that the inlet pipe is blocked. If the drainage pipe pressure value is less than the drainage pressure threshold, it indicates that the pressure in the drainage pipe has decreased while the drainage pump is draining water at the same pressure, indicating that the drainage pipe is leaking. Therefore, the abnormalities in the inlet and outlet pipes are determined to be a blockage in the inlet pipe and a leakage in the drainage pipe.
[0176] If the water inlet pipe pressure value is less than the water inlet pressure threshold, it indicates that the water inlet pipe pressure has decreased while the water supply pump is supplying water at the same pressure, indicating that the water inlet pipe is leaking. If the drainage pipe pressure value is greater than the drainage pressure threshold, it indicates that the drainage pipe pressure has increased while the drainage pump is draining water at the same pressure, indicating that the drainage pipe is also blocked. Therefore, the abnormality of the inlet and outlet pipes is determined to be a water inlet pipe leak and a drainage pipe blockage.
[0177] If the water inlet pipe pressure value is less than the water inlet pressure threshold, it proves that the water inlet pipe pressure has decreased while the water supply pump is supplying water at the same pressure, indicating that the water inlet pipe is leaking. If the drainage pipe pressure value is less than the drainage pressure threshold, it proves that the drainage pipe pressure has decreased while the drainage pump is draining water at the same pressure, indicating that the drainage pipe is leaking. Therefore, the abnormality in the inlet and outlet pipes is determined to be leaking simultaneously in the water inlet and drainage pipes.
[0178] Therefore, through the above method, the specific situation of the abnormality of the inlet and outlet water pipes can be further determined and sent to the display for display alarm, which facilitates relevant staff to promptly inspect and repair the problems in the pipes.
[0179] Furthermore, in another embodiment, after the electromagnetic flowmeter monitors the flow rate in the pipeline, it obtains monitoring results for the monitoring area and then generates a monitoring report based on the monitoring results. Specifically, separate monitoring reports are generated for different monitoring areas, namely, the living area and the entertainment area, thereby facilitating separate review of the monitoring results for the living area and the entertainment area.
[0180] The implementation principle of a pipeline flow monitoring method according to an embodiment of the present application is as follows: first, the monitoring area and the current time point of the pipeline are obtained, wherein the monitoring area includes the living area and the entertainment area. Then, it is determined whether the current time point matches a preset first time period. If the current time point matches the first time period, an entertainment area monitoring instruction is obtained, and the pipeline in the entertainment area is monitored according to the entertainment area monitoring instruction. If the current time point does not match the first time period, it is determined whether the current time point matches a preset second time period. If they do, a living area monitoring instruction is obtained, and the pipeline in the living area is monitored according to the living area monitoring instruction. If they do not match, an instruction to be monitored is obtained, and monitoring of the pipeline in the living area is stopped according to the instruction to be monitored. In this way, the flow in different areas can be monitored according to different time points, so that the monitoring time of the pipeline flow can be more consistent with the flow conditions of the corresponding area, thereby reducing the error generated during the monitoring process of the pipeline flow.
[0181] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
