Description

Technical Field

[0001] The present invention relates to the technical field of water supply management, and in particular to a secondary water supply water quality collaborative management platform system. Background Art

[0002] With the acceleration of urbanization, the secondary water supply system plays a vital role in ensuring water supply for urban residents. However, secondary water supply faces many challenges.

[0003] According to the publication number CN109087032B, a secondary water supply water quality collaborative management platform system is disclosed, which includes at least a management control unit, a water level management unit, a water volume management unit, a water quality management unit, a cleaning management unit, a cloud storage unit, a data analysis and query unit, and an account / bill management unit; wherein the management control unit is used to manage all data and communications in the platform system, and each sub-management unit is connected to and communicates with the client and the cloud server through the management control unit.

[0004] However, secondary water supply faces many challenges. On the one hand, water consumption fluctuates frequently and is difficult to accurately predict. Water demand varies greatly in different time periods (such as peak and trough periods) and different regions, which places high demands on the stable control of water supply pressure. On the other hand, water quality is easily affected by many factors, including changes in water supply volume that may cause changes in water flow in the pipe network, thereby disturbing pipe sediments and affecting the uniformity of disinfectant distribution, as well as fluctuations in raw water quality, aging of water supply facilities and surrounding environmental factors, which may cause changes in key indicators such as pH value, residual chlorine, and turbidity in water quality, threatening residents' water safety. Traditional secondary water supply management often relies on manual experience and simple monitoring methods, making it difficult to achieve accurate and coordinated management of water supply volume and quality, and unable to respond to various complex water supply conditions in a timely and effective manner. It is easy to have problems such as unstable water supply pressure and unqualified water quality, affecting the normal life and health of residents. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a secondary water supply water quality collaborative management platform system, which solves the problems of being unable to collaboratively manage secondary water supply according to actual conditions, being unable to respond to various complex water supply conditions in a timely and effective manner, and being prone to unstable water supply pressure and unqualified water quality.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A secondary water supply water quality collaborative management platform system, comprising: A water supply information acquisition module is used to acquire water quantity information of water supply and transmit the acquired water quantity information to a water supply quality analysis module; The water supply quality analysis module is used to perform water supply early warning analysis based on the acquired water volume information, compare the water supply volume with the preset value to generate a normal monitoring signal and a water quality early warning signal, and transmit the normal monitoring signal to the water supply management analysis module and the water quality early warning signal to the water quality early warning analysis module; The water quality early warning analysis module is used to analyze the acquired water quality early warning signals, generate water quality analysis information by sampling and analyzing the water quality of the water supply, and perform periodic analysis in combination with historical data, and transmit the water quality analysis information to the management information output module; The water supply management analysis module is used to analyze the normal monitoring signals obtained, conduct a comprehensive analysis of the water supply flow and water supply pressure corresponding to the secondary water supply area, and regulate the water supply in the secondary water supply area based on different water supply time periods, and generate water supply management information at the same time, and then transmit the water supply management information to the management information output module; The management information output module is used to display the acquired water quality analysis information and water supply management information to the corresponding management personnel.

[0007] As a further solution of the present invention, the specific method of the water supply quality analysis module to perform water supply early warning analysis on water quantity information is: Obtain the water volume information of the water supply, and compare the water volume information with the preset value. If the water volume information is greater than the preset value, it means that the current water supply exceeds the preset value, and a water quality warning signal is generated. Conversely, if the water volume information is less than the preset value, it means that the current water supply does not exceed the preset value, and a normal monitoring signal is generated.

[0008] As a further solution of the present invention, the specific method in which the water quality early warning analysis module analyzes the water quality early warning signal is: Obtain water quality warning signals, sample water supply, and obtain historical data. Then, based on the water quality changes in the historical data, obtain the time period t and the water quality indicators of the water supply within the time period t to determine the changes in the water quality indicators of the water supply. If the water supply quality index increases, an abnormal analysis signal is generated. Conversely, if the water supply quality index decreases, a normal monitoring signal is generated. At the same time, the normal monitoring signal is transmitted to the water supply management analysis module, and the generated abnormal analysis signal is analyzed and processed.

[0009] As a further solution of the present invention, the specific manner in which the water quality early warning analysis module analyzes and processes the generated abnormal analysis signal is: Obtain the specific increase index in the water supply quality index, and compare the obtained increase index with the warning value. If the increase index is greater than the warning value, a risk signal is generated. Conversely, if the increase index is less than the warning value, a warning signal is generated. At the same time, the generated risk signal and warning signal are transmitted to the management information output module.

[0010] As a further solution of the present invention, the specific method in which the water supply management analysis module analyzes the normal monitoring signal is: Obtain the secondary water supply area corresponding to the normal monitoring signal, and label the secondary water supply area as i, where i=1, 2, ..., j, where j represents the number of secondary water supply areas, and obtain the water supply information corresponding to the secondary water supply area i, and the water supply information includes: water supply volume, water supply pressure and water supply time, and obtain the water supply pressure Yi corresponding to the secondary water supply area; Then obtain the duration of the peak time period as Ti, and obtain the water supply flow rate per unit time as Q. Then substitute the obtained parameters into the formula The standard pressure Y1 is calculated, Q is the water supply flow rate, A is the cross-sectional area of ​​the pipe, V is the flow rate, and p is the pressure of the fluid. is the density of the fluid, h is the height of the fluid relative to a certain reference plane, and h remains unchanged in the horizontal pipe. The difference between the standard pressure Y1 and the water supply pressure Yi in the secondary water supply area is calculated and recorded as Yic. Similarly, the corresponding differences in all secondary water supply areas are calculated, and corresponding pressure adjustments are made according to the differences.

[0011] As a further solution of the present invention, the specific manner in which the water supply management analysis module performs corresponding pressure regulation according to the difference is: Obtain the corresponding high-pressure water supply area in the current time period, denoted as n, and n=1, 2, ..., m, where m represents the number of high-pressure water supply areas. Similarly, calculate the corresponding standard pressure using the above calculation method, and calculate the difference between the water supply pressure of the high-pressure water supply area and the standard pressure, and then sort them from large to small according to the calculated difference; Then, the difference corresponding to the secondary water supply area is obtained and sorted from large to small. Then, the difference of the high-pressure water supply area is matched with the difference of the secondary water supply area. At the same time, the corresponding water supply management information is generated based on the difference, and the water supply management information is transmitted to the management information output module.

[0012] As a further solution of the present invention, the specific manner in which the water supply management analysis module matches the difference between the high-pressure water supply area and the secondary water supply area is: Obtain the high-pressure water supply area corresponding to the maximum difference and the secondary water supply area corresponding to the maximum difference, and determine whether the difference between the two meets the difference requirement, and the value of the difference requirement is set by the operator. If the difference requirement is met, the high-pressure water supply area with the maximum difference is matched with the secondary water supply area with the maximum difference, and the water supply management information is generated based on the difference of the secondary water supply area. If it is not met, the differences of multiple high-pressure water supply areas are summed and the determination of the difference requirement is repeated; In this way, all secondary water supply areas are analyzed to generate water supply management information.

[0013] Beneficial Effects The present invention provides a secondary water supply water quality collaborative management platform system. Compared with the prior art, it has the following beneficial effects: The present invention uses a water supply information acquisition module to obtain water supply volume information in real time and accurately compare it with a preset value, so as to timely discover abnormal water supply volume and generate a corresponding water quality warning signal or a normal monitoring signal. After receiving the warning signal, the water quality warning analysis module comprehensively considers the changes in key indicators such as pH value, residual chlorine, turbidity, etc. through sampling and analysis of water supply quality and periodic analysis combined with historical data, and takes emergency response measures such as in-depth detection of water quality to ensure water quality safety.

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 This is a block diagram of the system principle of the present invention. DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] For example, see Figure 1 The present application provides a secondary water supply water quality collaborative management platform system, including: water supply information collection module, water supply water quality analysis module, water supply management analysis module, water quality early warning analysis module and management information output module, and at the same time by the attached Figure 1 It can be known that the above functional modules are electrically connected in a unidirectional manner.

[0017] The water supply information acquisition module is used to obtain the water quantity information of the water supply and transmit the obtained water quantity information to the water supply water quality analysis module.

[0018] Water supply quality analysis module, which is used to perform water supply early warning analysis based on the acquired water volume information, compare the water supply volume with the preset value to generate a normal monitoring signal and a water quality early warning signal, and at the same time transmit the normal monitoring signal to the water supply management analysis module and transmit the water quality early warning signal to the water quality early warning analysis module.

[0019] The water volume information of the water supply is obtained, and the water volume information is compared with the preset value. The specific value of the preset value is set by the operator. If the water volume information is greater than the preset value, it means that the current water supply exceeds the preset value and a water quality warning signal is generated. Conversely, if the water volume information is less than the preset value, it means that the current water supply does not exceed the preset value and a normal monitoring signal is generated.

[0020] For example, the currently monitored hourly water supply is 150 cubic meters. The operator sets the water supply warning threshold to 120 cubic meters based on the design capacity of the water supply system, historical water consumption peaks, and actual operational needs. When the acquired water volume information exceeds this preset value, such as the current 150 cubic meters is greater than 120 cubic meters, a water quality warning signal is generated. On the contrary, if the monitored water volume information is lower than the preset value, such as the water supply in a certain period of time is 100 cubic meters and less than 120 cubic meters, a normal monitoring signal is generated.

[0021] The water quality early warning analysis module is used to analyze the acquired water quality early warning signals, generate water quality analysis information by sampling and analyzing the water supply quality, and perform periodic analysis in combination with historical data, and transmit the water quality analysis information to the management information output module.

[0022] Obtain water quality warning signals, sample water supply, and obtain historical data at the same time. Then, based on the water quality changes in the historical data, the water quality changes here are indicators such as pH value, residual chlorine, turbidity, etc. in the water quality, obtain the time period t, and the specific value of the time period t is set by the operator, and obtain the water quality indicators of the water supply within the time period t to determine the changes in the water quality indicators of the water supply; If the water supply quality index increases, an abnormal analysis signal is generated. Conversely, if the water supply quality index decreases, a normal monitoring signal is generated. At the same time, the normal monitoring signal is transmitted to the water supply management analysis module, and the generated abnormal analysis signal is analyzed and processed; and here all water quality indicators are judged, including pH value, residual chlorine, turbidity and other indicators.

[0023] Obtain the specific increase index in the water supply quality index, and compare the obtained increase index with the warning value. If the increase index is greater than the warning value, a risk signal is generated. Conversely, if the increase index is less than the warning value, a warning signal is generated. At the same time, the generated risk signal and warning signal are transmitted to the management information output module.

[0024] Suppose that in a monitoring, it is found that the residual chlorine index shows an increasing trend, while the pH value and turbidity changes are relatively stable. The system will make a comprehensive judgment on this situation. Since the residual chlorine index increases, the increase index will be further compared with the warning value. If the warning value of residual chlorine is set to 4 mg / L, and the current monitored residual chlorine content has increased from the original stable 2 mg / L to 4.5 mg / L, which is greater than the warning value, the system will generate a risk signal, indicating that there may be a greater risk in water quality. For example, excessive disinfection may cause harmful by-products in the water. The risk signal is then transmitted to the management information output module so that relevant personnel can take emergency response measures in time, such as adjusting the amount of disinfectant added and conducting in-depth testing of water quality.

[0025] If the residual chlorine content only rises to 3.5 mg / L, which is less than the warning value, the system will generate a warning signal, indicating that the water quality has a potential change trend and that it is necessary to pay close attention to subsequent water quality dynamics. At the same time, the warning signal will be transmitted to the management information output module.

[0026] Management information output module, which is used to display the acquired risk signals and warning signals to the corresponding operators.

[0027] Embodiment 2, as Embodiment 2 of the present invention, is implemented on the basis of Embodiment 1, and differs from Embodiment 1 in that: The water supply management analysis module is used to analyze the normal monitoring signals obtained, conduct a comprehensive analysis of the water supply flow and water supply pressure corresponding to the secondary water supply area, and regulate the water supply in the secondary water supply area based on different water supply time periods. At the same time, it generates water supply management information, and then transmits the water supply management information to the management information output module.

[0028] The secondary water supply area corresponding to the normal monitoring signal is obtained, and the secondary water supply area is labeled as i, and i=1, 2, ..., j, where j represents the number of secondary water supply areas, and the water supply information corresponding to the secondary water supply area i is obtained, and the water supply information includes: water supply volume, water supply pressure and water supply time, and the water supply time here is the water supply time during the peak time period, and the water supply pressure Yi corresponding to the secondary water supply area is obtained; for example, for the secondary water supply area 3, during the peak time period of 7:00-9:00 in the morning, the water supply volume is 50 cubic meters, the water supply pressure Y3 is 0.4MPa, and the water supply flow rate Q corresponding to the unit time is known to be 25 cubic meters / hour, the peak time T3=2 hours, and the cross-sectional area A=0.1 square meters of the pipeline in this area and other related parameter information are obtained.

[0029] Then obtain the duration of the peak time period as Ti, and obtain the water supply flow rate per unit time as Q. Then substitute the obtained parameters into the formula The standard pressure Y1 is calculated, Q is the water supply flow rate, A is the cross-sectional area of ​​the pipe, V is the flow rate, and p is the pressure of the fluid. is the density of the fluid, h is the height of the fluid relative to a certain reference plane, and h is constant in the horizontal pipe, and the difference between the standard pressure Y1 and the water supply pressure Yi in the secondary water supply area is calculated and recorded as Yic. Similarly, the corresponding differences of all secondary water supply areas are calculated, and the corresponding pressure is adjusted according to the differences; Assume that through a series of calculations (herein involves a specific physical formula calculation process, such as calculating the flow velocity V=250 m / h based on the flow rate, and then substituting other parameters into the Bernoulli equation to calculate the pressure, etc.), the standard pressure Y of the secondary water supply area 3 during the peak period is obtained to be 0.35 MPa. Then the difference between the standard pressure Y and the water supply pressure Y3 of the secondary water supply area 3 is calculated, Y3c=Y3-Y1=0.4-0.35=0.05 MPa. In the same way, the corresponding differences of all secondary water supply areas are calculated one by one. After that, the system selects the current time. The high-pressure water supply area within the interval is marked as n, and its value range is from 1 to m, where m represents the number of high-pressure water supply areas. For example, it is found that secondary water supply area 5 and area 7 are high-pressure water supply areas, and their corresponding standard pressures are calculated respectively. Assuming that the water supply pressure of area 5 is 0.5MPa, the calculated standard pressure is 0.42MPa, and the difference is 0.08MPa; the water supply pressure of area 7 is 0.48MPa, the standard pressure is 0.4MPa, and the difference is 0.08MPa (if there are multiple high-pressure areas, sort them from large to small according to the difference).

[0030] The specific method of pressure regulation is: obtain the corresponding high-pressure water supply area in the current time period and record it as n, and n=1, 2, ..., m, where m represents the number of high-pressure water supply areas. Similarly, the above calculation method is used to calculate the corresponding standard pressure, and the difference between the water supply pressure of the high-pressure water supply area and the standard pressure is calculated, and then the calculated difference is sorted from large to small; Then, the difference values ​​corresponding to the secondary water supply areas are obtained, and the difference values ​​are sorted from large to small. Then, the difference values ​​of the high-pressure water supply areas are matched with the difference values ​​of the secondary water supply areas. The specific matching process is: the high-pressure water supply area corresponding to the maximum difference value and the secondary water supply area corresponding to the maximum difference value are obtained, and it is judged whether the difference value between the two meets the difference value requirement, and the value of the difference value requirement is set by the operator. If the difference value requirement is met, the high-pressure water supply area with the maximum difference value is matched with the secondary water supply area with the maximum difference value, and the water supply management information is generated based on the difference value of the secondary water supply area as the standard. If it is not met, the difference values ​​of multiple high-pressure water supply areas are summed, and the judgment of the difference value requirement is repeated; In this way, all secondary water supply areas are analyzed to generate water supply management information. At the same time, corresponding water supply management information is generated based on the difference as a standard, and the water supply management information is transmitted to the management information output module.

[0031] Then, the difference of the high-pressure water supply area is matched and compared with the difference of all secondary water supply areas. For example, if the difference of 0.08MPa of the high-pressure water supply area 5 is found to be close to the difference of the secondary water supply area 9 (or meets a certain matching rule), then specific water supply management information is generated based on the difference, such as prompting to adjust the water supply pressure of area 9 appropriately, or checking whether there is an abnormality in the pipe network near area 9 that causes pressure fluctuations, etc., and the water supply management information is transmitted to the management information output module.

[0032] A management information output module is used to display the acquired water supply management information to the corresponding management personnel.
