Description

Technical Field

[0001] The present invention relates to the technical field of underground integrated pump stations, and more specifically, to a smart underground integrated pressure-regulating pump station control system. Background Art

[0002] An underground integrated pressure-regulating pump station is a pressure-regulating facility that integrates multiple devices and functions underground. The functions of an underground integrated pressure-regulating pump station mainly include: regulating water pressure: ensuring that the pressure in the water supply or drainage system remains within a reasonable range to meet user needs; ensuring flow rate: stable pressure is conducive to maintaining a constant flow rate and improving the reliability of system operation; emergency standby: when the main system fails or is under maintenance, it can be put into use quickly to ensure normal operation.

[0003] During the operation of the underground integrated pressure regulating pump station, the normal operation of its power supply and water supply is the key to the normal operation of the underground integrated pressure regulating pump station. Therefore, it is necessary to supervise the power supply and water supply during the operation of the underground integrated pressure regulating pump station;

[0004] The patent application with reference publication number CN113050527A discloses an integrated intelligent pump station control system, which involves the field related to sewage treatment, and is intended to solve the problem that the control system of the existing integrated intelligent pump station is not comprehensive enough, resulting in inconvenience in use and failure to meet actual work needs; the pump station control system is bidirectionally connected with the pump station protection system, the pump station detection system, the human-computer interaction display control system, the pump station and the network transmission module, the network transmission module is bidirectionally connected with the management terminal, the pump station protection system includes a remote start-stop module, a backup power supply module, a humidity alarm module and a smoke alarm module, the pump station detection system includes a pressure monitoring module, a flow monitoring module, an electric energy monitoring module, a water level monitoring module and a water quality monitoring module, one end of the pump station is provided with a water inlet pipe, and a filter box is installed below one end of the water inlet pipe;

[0005] However, when the existing technology conducts abnormal supervision and early warning on the power supply and water supply ends during the operation of the pump station, the analysis data is single, and the power supply data, display data and water supply data cannot be comprehensively analyzed, resulting in large errors in the analysis results, affecting the management efficiency of the pump station. In addition, the traditional supervision method cannot comprehensively supervise the pump station from the three perspectives of power supply, status display and water supply, which in turn causes the power supply end of the pump station to affect the stable operation of the pump station, and the water flow and water pressure in the waterway of the water supply pipeline are prone to instability, making it easy for the water supply pipeline to not supply water or leak, which in turn leads to poor working stability of the pump station.

[0006] To this end, we propose a smart underground integrated pressure regulating pump station control system to address the above problems. Summary of the invention

[0007] The purpose of the present invention is to solve the above-mentioned problems. Compared with the prior art, a smart underground integrated pressure-regulating pump station control system is provided. The present invention conducts comprehensive abnormal supervision of the pump station from three angles: power supply, status display and water supply, which is beneficial to improving the accuracy of the analysis results and the supervision efficiency as a whole, and is convenient for timely early warning management of the pump station to improve the operational safety and stability of the pump station. In addition, the working data of the water supply pipeline of the pump station is inspected, evaluated and analyzed in depth, so as to understand the situation of the water supply pipeline under the premise that the power supply and water supply of the pump station are normal, and to facilitate timely replacement and management of the water supply pipeline on the pump station to ensure the operational stability and safety of the pump station.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0053] Embodiment 1: The present invention discloses a smart underground integrated pressure regulating pump station control system, please refer to Figure 1 and Figure 2 , including a management and control platform, a data acquisition module, a power supply supervision module, an equipment operation feedback module, a safety supervision module, a water supply supervision module, a pipeline supervision module and an early warning display module, the management and control platform is connected to the acquisition module in a one-way communication, the data acquisition module is connected to the power supply supervision module and the equipment operation feedback module in a one-way communication, the power supply supervision module and the equipment operation feedback module are connected to the safety supervision module in a one-way communication, the power supply supervision module and the equipment operation feedback module are connected to the early warning display module in a one-way communication, the early warning display module is connected to the safety supervision module in a one-way communication, the safety supervision module is connected to the water supply supervision module in a one-way communication, and the water supply supervision module is connected to the pipeline supervision module in a one-way communication;

[0054] When the control platform generates an operation and management instruction and sends it to the data acquisition module, the data acquisition module immediately collects the power supply data and display data of the pump station operation after receiving the operation and management instruction. The power supply data includes the operating voltage, line reactive power value and line loss value of the internal line of the pump station. The display data includes the abnormal sound value, internal temperature value and average vibration frequency of the pump station. The power supply data and display data are sent to the power supply supervision module and the equipment operation feedback module respectively. After receiving the power supply data, the power supply supervision module immediately performs operation stability supervision evaluation and analysis on the power supply data to determine whether the power supply end of the pump station is normal, so as to ensure the stability of the pump station operation and reduce the abnormal risk of the pump station. The specific operation stability supervision evaluation and analysis process is as follows:

[0055] The duration of the pump station operation for a period of time is collected and marked as a time threshold. The time threshold is divided into i sub-time periods, i is a natural number greater than zero, and the sub-time period is divided into m sub-time nodes, m is a natural number greater than zero. The operation imbalance value within the time threshold is obtained. The operation imbalance value represents the ratio between the part of the change difference of the internal line of the pump station in each sub-time period that is greater than the preset change difference threshold and the change difference. The change difference represents the difference between the maximum and minimum values ​​of the voltage change value. The voltage change value represents the difference between the operating voltages of the internal lines of the pump station in two connected sub-time nodes. The larger the value of the operation imbalance value, the greater the risk of abnormal operation of the pump station.

[0056] The line operation risk value of the internal line of the pump station within the time threshold is obtained. The line operation risk value represents the product of the total number of line operation risk sections and the line loss value after data normalization. The line operation risk section represents the sub-time period corresponding to the line reactive power value being greater than the preset line reactive power value threshold. The line operation risk value is an influencing parameter reflecting the operation status of the pump station;

[0057] Compare and analyze the operation imbalance value and line operation risk value with the preset operation imbalance value threshold and preset line operation risk value threshold that are stored internally:

[0058] If the operation imbalance value is less than the preset operation imbalance value threshold, and the line operation risk value is less than the preset line operation risk value threshold, no signal is generated;

[0059] If the operation imbalance value is greater than or equal to the preset operation imbalance value threshold, or the line operation risk value is greater than or equal to the preset line operation risk value threshold, an abnormal signal is generated and sent to the early warning display module. After receiving the abnormal signal, the early warning display module immediately displays the preset early warning text corresponding to the abnormal signal, so as to remind the operation management personnel to timely control and maintain the power supply end of the pump station to ensure the stability of the power supply of the pump station and the operation safety of the pump station;

[0060] After receiving the display data, the equipment operation feedback module immediately performs operation feedback supervision and analysis on the display data, so as to analyze it from the perspective of the pump station operation display characteristics and judge whether the pump station operation display is normal, so as to improve the operation supervision and early warning effect of the pump station. The specific operation feedback supervision and analysis process is as follows:

[0061] SS1: Obtain the abnormal sound value of the pump station in each sub-time node, and construct a set A of abnormal sound values ​​based on it, obtain the mean in set A, and mark the mean in set A as the abnormal sound mean, establish a rectangular coordinate system with time as the X-axis and the abnormal sound mean as the Y-axis, draw the abnormal sound mean curve by plotting points, and draw the preset abnormal sound mean threshold curve in the coordinate system at the same time, obtain the product value of the time length corresponding to the line segment above the preset abnormal sound mean threshold curve and the area enclosed by the upper line segment and the preset abnormal sound mean threshold curve from the coordinate system after data normalization, and mark it as the abnormal operation risk value YF. The larger the value of the abnormal operation risk value YF, the greater the abnormal operation risk of the pump station;

[0062] SS2: Obtain the internal temperature value of the pump station in each sub-time node, obtain the difference between the internal temperature values ​​of two connected sub-time nodes, mark the average of the difference between the internal temperature values ​​of the two connected sub-time nodes as the temperature change value, establish a rectangular coordinate system with time as the X-axis and the temperature change value as the Y-axis, draw the temperature change value curve by plotting points, and draw the preset temperature change value threshold curve in the coordinate system. Obtain the acute angle value formed when the temperature change value curve intersects with the preset temperature change value threshold curve for the first time from the coordinate system, and mark it as the risk temperature change angle FW. The larger the value of the risk temperature change angle FW, the greater the risk of abnormal internal temperature when the pump station is running. At the same time, obtain the average vibration frequency PZ of the pump station within the time threshold. The average vibration frequency PZ is an influencing parameter reflecting the operating status of the pump station;

[0063] SS3: By formula The display feature evaluation coefficient is obtained, where b1, b2 and b3 are preset proportional factor coefficients of the abnormal operation risk value, risk temperature change angle and average vibration frequency respectively. The proportional factor coefficient is used to correct the deviation of various parameters in the formula calculation process, so as to make the calculation result more accurate. b1, b2 and b3 are all positive numbers greater than zero. b4 is the preset fault tolerance factor coefficient with a value of 2.236. The obtained display feature evaluation coefficient BT is sent to the safety supervision module, and the display feature evaluation coefficient BT is compared and analyzed with the preset display feature evaluation coefficient threshold value stored in the internal input:

[0064] If the ratio between the display feature evaluation coefficient BT and the preset display feature evaluation coefficient threshold is less than 1, no signal is generated;

[0065] If the ratio between the display characteristic evaluation coefficient BT and the preset display characteristic evaluation coefficient threshold is greater than or equal to 1, an alarm signal is generated and sent to the early warning display module. After receiving the alarm signal, the early warning display module immediately displays the preset alarm text corresponding to the alarm signal, so as to remind the operation management personnel to timely control and maintain the pump station to ensure the operation safety of the pump station, and at the same time, it is conducive to improving the operation supervision and early warning effect of the pump station;

[0066] After receiving the display characteristic evaluation coefficient BT, the safety supervision module immediately conducts a comprehensive evaluation and analysis on the display characteristic evaluation coefficient BT to determine whether the overall display of the pump station is normal, so as to facilitate timely early warning management and improve the operation safety and stability of the pump station. The specific comprehensive evaluation and analysis process is as follows:

[0067] T1: retrieve the operation imbalance value and the line operation risk value from the power supply supervision module, label the operation imbalance value and the line operation risk value as YS and XF respectively, and obtain the display characteristic evaluation coefficient BT at the same time;

[0068] T2: By formula The operation safety assessment coefficient is obtained, where c1, c2 and c3 are respectively the preset weight factor coefficients of the operation imbalance value, the line operation risk value and the display characteristic assessment coefficient, c1, c2 and c3 are all positive numbers greater than zero, c4 is the preset compensation factor coefficient, and the value is 2.118. The operation safety assessment coefficient YA is compared and analyzed with the preset operation safety assessment coefficient threshold value stored in the internal entry:

[0069] If the operation safety assessment coefficient YA is less than the preset operation safety assessment coefficient threshold, a normal signal is generated and sent to the water supply supervision module;

[0070] If the operation safety assessment coefficient YA is greater than or equal to the preset operation safety assessment coefficient threshold, a risk signal is generated and sent to the early warning display module. After receiving the risk signal, the early warning display module immediately displays an early warning with the text "operation risk" to facilitate timely early warning management of the pump station, so as to improve the operation safety and stability of the pump station, and integrate the power supply and display information for analysis, which is conducive to improving the accuracy of the analysis results.

[0071] Embodiment 2: The technical solution of the embodiment of the present invention is different from that of embodiment 1 in that: after receiving the normal signal, the water supply monitoring module immediately collects the water supply data of the pump station operation, the water supply data includes the water level value of the clear water tank in the pump station, the water supply flow value of the pump station and the water supply pressure value of the pump station, and monitors, evaluates and analyzes the water supply data to determine whether the water supply end is operating normally, so as to ensure the normal supply of water in the pump station. The specific water supply stability monitoring, evaluation and analysis process is as follows:

[0072] TT1: Obtain the water level value of the clear water tank in the pumping station within the time threshold, the water supply flow value of the pumping station and the water supply pressure value of the pumping station, and label the water level value of the clear water tank in the pumping station, the water supply flow value of the pumping station and the water supply pressure value of the pumping station as SW, GL and GY respectively. The water level value SW of the clear water tank in the pumping station, the water supply flow value GL of the pumping station and the water supply pressure value GY of the pumping station are all average values ​​within the monitoring period;

[0073] TT2: By formula The water supply stability assessment coefficient is obtained, where f1, f2 and f3 are all preset proportional coefficients, and f1>f2>f3>1. is the error correction factor, with a value of 0.984, and compares and analyzes the water supply stability assessment coefficient GW with the preset water supply stability assessment coefficient threshold value stored in the internal input;

[0074] If the water supply stability assessment coefficient GW is less than the preset water supply stability assessment coefficient threshold, a feedback instruction is generated and sent to the pipeline supervision module;

[0075] If the water supply stability assessment coefficient GW is greater than or equal to the preset water supply stability assessment coefficient threshold, an impact signal is generated and sent to the early warning display module. After receiving the impact signal, the early warning display module immediately displays an early warning with the text "abnormal water supply", so as to facilitate timely management of the pump body inside the pump station, and to adjust the water level of the clear water tank in the pump station, the water supply flow of the pump station and the water supply pressure of the pump station accordingly to ensure the operation efficiency of the pump station;

[0076] After receiving the feedback instruction, the pipeline supervision module immediately collects the working data of the water supply pipeline of the pump station, including the water flow rate and water pressure value per unit time inside the water supply pipeline, and checks, evaluates and analyzes the working data, so as to understand the situation of the water supply pipeline under the premise that the power supply and water supply of the pump station are normal, so as to facilitate the timely replacement and management of the water supply pipeline on the pump station to ensure the operation stability and safety of the pump station. The specific inspection, evaluation and analysis process is as follows:

[0077] Z1: Divide the water supply pipeline into n sub-length segments, where n is a natural number greater than zero, obtain the water flow rate per unit time in each sub-length segment within the time threshold, obtain the maximum and minimum values ​​of the water flow rate per unit time in the sub-length segment, and mark the difference between the maximum and minimum values ​​of the water flow rate per unit time in the sub-length segment as the flow rate difference. The larger the value of the flow rate difference, the greater the risk of leakage in the water supply pipeline;

[0078] Z2: Obtain the water pressure value in each sub-length segment within the time threshold, obtain the maximum and minimum water pressure values ​​in the sub-length segment, and mark the difference between the maximum and minimum water pressure values ​​in the sub-length segment as the dangerous water pressure difference, which is an influencing parameter reflecting the risk of water supply pipeline leakage;

[0079] Z3: Compare and analyze the flow rate difference and dangerous water pressure difference with the preset flow rate difference and dangerous water pressure difference thresholds stored in the internal data:

[0080] If the flow rate difference is less than the preset flow rate difference threshold, and the dangerous water pressure difference is less than the preset dangerous water pressure difference threshold, no signal is generated;

[0081] If the flow rate difference is greater than or equal to the preset flow rate difference threshold, or the dangerous water pressure difference is greater than or equal to the preset dangerous water pressure difference threshold, a danger signal is generated and sent to the early warning display module via the water supply supervision module. After receiving the danger signal, the early warning display module immediately performs the preset early warning operation corresponding to the danger signal, so as to facilitate timely early warning management, so as to ensure the operating safety of the pump station, reduce the occurrence rate of accidents, and more comprehensively supervise and warn the operation of the pump station. Comprehensive abnormal supervision from the three angles of power supply, status display and water supply is beneficial to improve the accuracy of analysis results and supervision efficiency as a whole.

[0082] In summary, the present invention conducts comprehensive abnormal supervision on the pump station from three perspectives: power supply, status display, and water supply, which is beneficial to improving the accuracy of the analysis results and the supervision efficiency as a whole, and is convenient for timely early warning management of the pump station to improve the operational safety and stability of the pump station, that is, the power supply data is subjected to operational stability supervision evaluation analysis to reduce the impact of the power supply end on the operation of the pump station, and the display data is subjected to operational feedback supervision analysis to analyze from the perspective of the pump station operation display characteristics to determine whether the pump station operation display is normal, so as to improve the operation supervision and early warning effect of the pump station, and the power supply and display information are integrated and analyzed. It is beneficial to improve the accuracy of the monitoring and analysis results of the pump station, and to conduct water supply stability monitoring, evaluation and analysis on the water supply data at the water supply end of the pump station under the premise that the power supply and display of the pump station are normal, to determine whether the water supply end is operating normally, so as to ensure the normal supply of water to the pump station, and to manage the pump body inside the pump station through information feedback to ensure the operation efficiency of the pump station, and to conduct in-depth inspection, evaluation and analysis of the working data of the water supply pipeline of the pump station, so as to understand the situation of the water supply pipeline under the premise that the power supply and water supply of the pump station are normal, so as to facilitate the timely replacement and management of the water supply pipeline on the pump station to ensure the operation stability and safety of the pump station.
