[0002] Domestic sewage often contains a large amount of particulate impurities and sediments, which can easily cause blockage of the sewage treatment plant's water pumps.

[0027] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0029] Embodiment 1

[0030] Figure 1A flow chart of a method for monitoring the blockage status of a water pump provided in Example 1 of the present invention. This embodiment is applicable to the situation where the blockage status of a water pump is monitored without adding hardware equipment. The method can be executed by a device for monitoring the blockage status of a water pump. The device can be implemented in the form of hardware and / or software. The device can be configured in a water pump system having a PLC connected to an industrial computer.

[0031] like Figure 1 As shown, the method includes:

[0032] S110, acquiring the working data of the water pump to be monitored in the current pump station in real time, and substituting the current value in the working data into a pre-set flow calculation function matching the water pump to be monitored to obtain the actual flow of the water pump to be monitored.

[0033] The working data of the monitored water pump may include the current current, frequency, flow rate, etc. of the water pump. A monitored water pump has at least one pre-set flow rate calculation function for calculating the actual flow rate of the monitored water pump. The flow rate calculation function is a linear function that describes the linear relationship between current and flow rate.

[0034] S120: Compare the actual flow rate with the flow rate threshold to determine the blockage condition of the water pump to be monitored.

[0035] S130. When the actual flow rate is less than the flow rate threshold, the system enters the warning state and sends a warning signal to the administrator.

[0036] The flow rate threshold is set to analyze the blockage degree of the water pump. When the actual flow rate of the water pump is less than the flow rate threshold, it means that the current flow rate value of the water pump is too low and there is a possibility of blockage. The warning signal can be specifically manifested as a yellow warning light as a reminder to the administrator.

[0037] Optionally, when the actual flow rate is less than the flow rate threshold, before entering the warning state and sending a warning signal to the administrator, the following may also be included:

[0038] Extracting the rated flow value of the water pump to be monitored from the historical working data of the water pump to be monitored;

[0039] Multiply the rated flow value by the preset specific gravity value to obtain the flow threshold of the water pump to be monitored.

[0040] The monitored water pump has a rated flow rate under normal conditions at each rated working frequency, and the rated flow rate can refer to the theoretical maximum efficiency point of the water pump when the valve opening is constant. In the embodiment of the present invention, the flow rate threshold of the monitored water pump = specific gravity × rated flow rate value.

[0041] Furthermore, when the actual flow rate is less than the flow rate threshold, the warning state is entered, and before the warning signal is sent to the administrator, the following may also be included:

[0042] Collect the blocking flow value in a blocking state within a certain period from the historical working data of the water pump to be monitored;

[0043] The average value of the blockage flow value is calculated to obtain the flow threshold value of the water pump to be monitored.

[0044] Additionally, using the average value of the blocking flow value as the flow threshold is another way to set the flow threshold. In actual application, one of the two flow thresholds can be selected according to actual conditions.

[0045] S140, recording the duration of the warning state. When the duration is longer than a preset calculation period, determining that the monitored water pump is blocked, and sending a fault signal to the administrator.

[0046] In actual application scenarios, the calculation cycle is generally 3 to 5 calculation cycles, wherein a calculation cycle can be 1 to 2 minutes, which can be preset according to the actual situation. When the warning state is entered, the timing starts. When the uninterrupted duration of the warning state exceeds the preset calculation cycle, the monitored water pump changes from the warning state to the alarm state. In addition to issuing a fault signal to the administrator, the color of the warning light can also change from yellow to red as a reminder to the administrator.

[0047] The embodiment of the present invention pre-builds a flow calculation function for a water pump under a specific working frequency, and can calculate the flow state of the water pump at the current moment by collecting the current value of the water pump, and accurately judge the blockage state of the water pump by comparing it with the pre-built flow threshold. Since most of the existing technologies use the method of adding a detection device to judge the blockage degree of the water pump, the embodiment of the present invention does not need to change the existing process flow, and only needs to analyze the working data of the pump station to monitor the blockage state of the water pump for the management personnel in real time. It is easy to implement and promote in actual application places such as sewage treatment plants, reducing costs and increasing efficiency for enterprises.

[0048] Embodiment 2

[0049] Figure 2 This is a flow chart of another method for monitoring the blockage state of a water pump provided in the second embodiment of the present invention. This embodiment is refined based on the above embodiment. Figure 2 As shown, the method specifically includes:

[0050] S210, collecting historical working data of the current pumping station, and counting the working frequency quantity of each water pump in the current pumping station according to the historical working data.

[0051] Specifically, the historical working data of the pump station includes data in normal working state and blocked state, which may include: water pump switch signal, water pump current, water pump voltage, water pump working frequency, etc. Among them, each water pump has at least one working frequency, such as a water pump with a frequency of 50HZ AC or a water pump with a frequency of 30HZ AC.

[0052] S220: construct a flow calculation function corresponding to at least one operating frequency for each water pump.

[0053] Optionally, a flow calculation function corresponding to at least one power frequency is constructed for each water pump, including:

[0054] Preprocessing the historical working data of the target water pump to obtain first historical working data under a first working frequency;

[0055] Performing sample division on the first historical working data to obtain first training set data for constructing a first flow calculation function and first test set data for verifying the accuracy of the first flow calculation function;

[0056] Substitute the first training set data into the original linear function, and calculate the slope value k1 and the intercept value b1 of the original linear function under the first power frequency;

[0057] According to the slope value k1 and the intercept value b1, a first flow calculation function under the first power frequency is constructed;

[0058] The first test set data is substituted into the first flow calculation function for accuracy verification, and the verified first flow calculation function is used as the preset flow calculation function under the first working frequency of the target water pump.

[0059] The preprocessing operation includes screening the missing value or abnormal value data to obtain the historical working data that meets the accuracy and consistency requirements. In the embodiment of the present invention, only the flow calculation function construction method under one working frequency of the target water pump is explained, and the same method is adopted for water pumps with multiple working frequencies. Specifically, the original linear function of the form y=kx+b is substituted into the flow value y and the current value x in the first training set data to calculate the slope value k and the intercept value b, that is, to construct the first flow calculation function with known k and b.

[0060] Furthermore, substituting the first test set into the first flow calculation function for accuracy verification includes:

[0061] Calculating the arithmetic mean of the current values ​​of the first training set data to obtain a first current value, substituting the first current value into a first flow calculation function to obtain a first flow value;

[0062] Calculate the arithmetic mean of the current values ​​of the first test set data to obtain a second current value, substitute the second current value into the first flow calculation function to obtain a second flow value;

[0063] The deviation between the first flow value and the second flow value is calculated. If the deviation is less than the deviation threshold, the first flow calculation function passes the accuracy check, and the first flow calculation function is used as the preset flow calculation function under the first working frequency of the target water pump.

[0064] The first flow value y corresponding to the first current value x is obtained by calculating the current average value (first current value) of the first training set data and substituting it as x into the first flow calculation function with known k and b. The first flow value y is used as a standard value for comparison with the second current y calculated using the first test set data, wherein if the deviation range of the second current value as a test value from the standard value is less than a preset deviation threshold, indicating that the error between the standard value and the test value is within an acceptable range, the first flow calculation function is used as the final preset flow calculation function for subsequent actual flow measurement.

[0065] Furthermore, after calculating the deviation between the first flow value and the second flow value, the method further includes:

[0066] If the deviation value is greater than the deviation threshold, the first flow calculation function fails the accuracy check;

[0067] At this time, the process returns to execute preprocessing of the historical working data of the target water pump to obtain new first historical working data under the first working frequency;

[0068] A new first flow calculation function is constructed using the new first historical working data;

[0069] The above steps are repeated until the new first flow calculation function passes the accuracy check, and the new first flow calculation function is used as the preset flow calculation function under the first working frequency of the target water pump.

[0070] On the contrary, if the deviation range of the second current value as a test value from the standard value is greater than the preset deviation threshold, it means that the error between the standard value and the test value exceeds the acceptable range, and the first flow calculation function needs to be corrected. The correction method is to re-preprocess the historical working data to obtain new historical working data, and create a new training set and test set based on the new historical working data. The above steps are repeated until the deviation value between the flow test value under the new test set data and the flow standard value under the new training set data is less than the deviation threshold. The flow calculation function obtained by this round of verification can be used as the final preset flow calculation function.

[0071] S230, acquiring the working data of the water pump to be monitored in the current pump station in real time, and extracting all the working frequencies of the water pump to be monitored from the working data.

[0072] S240. From all flow calculation functions corresponding to the water pump to be monitored, obtain a target flow calculation function that matches the power frequency, and substitute the current value in the working data into the target flow calculation function to obtain the actual flow of the water pump to be monitored.

[0073] By extracting all the working frequencies of the water pump to be monitored at present, each working frequency can be matched with its corresponding target flow calculation function. After collecting the current value x of the water pump to be monitored at each working frequency at the current moment, it is input into the target flow calculation function to obtain the actual flow value y of the water pump to be monitored at the target working frequency at the current moment.

[0074] S250: Compare the actual flow rate with the flow rate threshold to determine the blockage condition of the water pump to be monitored.

[0075] S260: When the actual flow rate is less than the flow rate threshold, the system enters the warning state and sends a warning signal to the administrator.

[0076] S270, recording the duration of the warning state. When the duration is longer than a preset calculation period, determining that the monitored water pump is blocked, and sending a fault signal to the administrator.

[0077] The technical solution of the embodiment of the present invention explains the construction method of the preset flow calculation function by refining the overall solution, including the verification process of the flow calculation function, so as to ensure the accuracy of the actual flow value calculation, so that the water pump can operate in the best working state and avoid greater losses caused by blockage. At the same time, in order to avoid the randomness of the judgment result, for water pumps that may be congested, the administrator will be drawn to the attention by first turning on the warning light to prompt, and the duration of the warning state is counted to determine whether the water pump that may be congested is really congested, thereby reducing unnecessary manual unblocking times and improving production efficiency.
