Description

Technical Field

[0001] The present invention relates to the technical field of water quality monitoring in pump houses, and particularly to a water quality monitoring system for intelligent pump houses of secondary water supply. Background Art

[0002] The intelligent secondary pump house is a modern water treatment facility designed to enhance the intelligence and efficiency of urban water supply systems. Its main function is to ensure the stability and safety of the water supply system through intelligent control and management of pumps. The intelligent secondary pump house is equipped with advanced automation equipment and control systems, including intelligent pumps, sensors, frequency converters, and remote monitoring systems. The intelligent pump can automatically adjust its operating state according to real-time water demand, achieving energy conservation and emission reduction. The sensors are used to monitor the operating parameters of the pump in real time, such as pressure, flow rate, and temperature, to ensure that the pump house operates in the best state. In addition, the frequency converter can adjust the speed of the pump to adapt to different water demands, further improving energy efficiency.

[0003] By integrating an advanced remote monitoring system, the intelligent secondary pump house can achieve real-time monitoring and management of pump house equipment. Operators can obtain the operating data of the pump house at any time through a computer or mobile device, and promptly discover and handle potential problems. This remote monitoring not only improves the operation and maintenance efficiency of the equipment, but also reduces the need for manual intervention and lowers the operation cost. The control system of the pump house can optimize the operation strategy of the pump through an automated scheduling algorithm to ensure the stability of water supply pressure and flow rate, while reducing energy consumption and maintenance costs.

[0004] In addition, a water quality monitoring system is also required in the intelligent secondary pump house to effectively monitor the water quality of the tap water transported by the pump house. Currently, each pump house has a one-to-one water quality monitoring system, and it is impossible to uniformly coordinate the water quality monitoring data of the intelligent secondary pump houses in the entire area. Therefore, when the water quality monitoring system in any intelligent secondary pump house is damaged, the water quality situation in that intelligent secondary pump house cannot be fed back. Similarly, if multiple sets are damaged, there will be a problem that the water quality in a large number of intelligent secondary pump houses cannot be detected, ultimately affecting the monitored and guaranteed water quality of the output.

[0005] Therefore, a water quality monitoring system for intelligent pump houses of secondary water supply is proposed to solve or alleviate the above problems. Summary of the Invention

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0052] A water quality monitoring system for a secondary water supply intelligent pump house, as Figure 1 shown, includes a water quality data acquisition module, a water quality safety analysis module, and a pollution area analysis module;

[0053] The water quality data acquisition module is used to collect the water quality data of the pump house, preprocess it, and then feedback it to the water quality safety analysis module;

[0054] The water quality safety analysis module is used to analyze whether there is pollution in the water quality according to the water quality data of some pump houses. If there is pollution, the analysis result will be feedback to the pollution area analysis module. If there is no pollution, the analysis result will be directly feedback;

[0055] The pollution area analysis module is used to analyze and confirm the pump houses that may be polluted according to the analysis result of the water quality safety analysis module and through a prediction model, and then control the water quality data acquisition module of the pump houses that may be polluted to collect the water quality data of the pump houses, and then the water quality safety analysis module analyzes whether there is pollution in the water quality and directly feedbacks the analysis result.

[0056] This system collects key water quality parameters through the water quality data acquisition module, such as turbidity, total organic carbon, total nitrogen, total phosphorus, ammonia nitrogen, etc. These parameters are key indicators for evaluating water quality. Based on modular design, the water quality monitoring function of this system is divided into three modules: data acquisition, safety analysis, and pollution area analysis. The data acquisition module is responsible for collecting and preprocessing water quality data in real time, and then transmitting it to the water quality safety analysis module. The water quality safety analysis module uses preset rules and thresholds to analyze the collected data to determine whether there is pollution. Once pollution is detected, the system will activate the pollution area analysis module. This module analyzes the pump houses that may be polluted through a prediction model and guides the corresponding data acquisition module to conduct further water quality detection.

[0057] In this way, not only the accuracy and response speed of monitoring are improved, but also the robustness and reliability of the system are enhanced through the collaborative work between modules. Even if some monitoring devices fail, the system can still continue to perform monitoring tasks through other normally working modules to ensure water supply safety.

[0058] Preferably, the number of water quality data acquisition modules is several. Each water quality data acquisition module separately acquires the water quality data of a single pump house, preprocesses it, and then feeds it back to the water quality safety analysis module. The water quality data of the pump house includes the turbidity, total organic carbon (TOC), total nitrogen (TN), total phosphorus (TP), ammonia nitrogen (NH 3 .

[0059] By deploying multiple water quality data acquisition modules, each responsible for collecting the water quality data of a single pump house, including key indicators such as turbidity, total organic carbon, total nitrogen, total phosphorus, and ammonia nitrogen, the system can obtain more detailed water quality information and provide accurate data support for subsequent water quality safety analysis in this way.

[0060] Preferably, after collecting and preprocessing the water quality data of the pump house and feeding it back to the water quality safety analysis module, the following steps are included:

[0061] Determine that the total number of water quality data acquisition modules is n;

[0062] Calculate the number of water quality data acquisition modules k to be selected, where k = n / 2. If n is odd, then k is rounded up;

[0063] Create a list containing all the identifiers of the water quality data acquisition modules ;

[0064] Use the Fisher-Yates shuffle algorithm to shuffle the identifiers of the water quality data acquisition modules in the list;

[0065] According to the shuffled list, select the first k identifiers of the water quality data acquisition modules as the selected water quality data acquisition modules;

[0066] Only arrange the selected water quality data acquisition modules to collect the water quality data of the pump house.

[0067] Through the above method, the water quality data acquisition process is optimized to ensure the representativeness of the data and the robustness of the system. Determine the total number of water quality data acquisition modules, calculate the number of modules to be selected, create a list containing all module identifiers, and use the Fisher-Yates shuffle algorithm to randomly shuffle the list order, so as to select some modules for water quality data acquisition. This method improves the randomness and fairness of data acquisition through a randomized selection mechanism, avoiding the bias that may be brought by a fixed acquisition mode. At the same time, by collecting data on the selected modules on the same time axis, obtaining the maximum and minimum values, and performing data standardization processing, an accurate water quality data matrix is formed, providing high-quality input data for subsequent water quality safety analysis. This process not only enhances the anti-interference ability of the system but also ensures that when some monitoring devices are damaged, the system can still effectively monitor the water quality through other normally working modules.

[0068] Preferably, the Fisher-Yates shuffle algorithm is used to shuffle the identification numbers of the water quality data acquisition modules in the list, including the following steps:

[0069] For each index from i to 1, typically i starts from n - 1, where n is the length of the list: , , where denotes generating a random integer within the closed interval , denotes the elements at positions a and b in the list.

[0070] Through the above steps, the accuracy and reliability of the water quality monitoring system are enhanced. The principle of this solution is to randomly sort the identification numbers of the water quality data acquisition modules using the Fisher-Yates shuffle algorithm, thereby ensuring that the module selection for each data acquisition is random and avoiding biases that may be introduced by selecting modules in a fixed order.

[0071] Preferably, after collecting and preprocessing the water quality data in the pump house, it is fed back to the water quality safety analysis module, and the following steps are also included:

[0072] Collect several water quality data of the pump house at the same time axis for the selected water quality data acquisition module;

[0073] Traverse all data values of each water quality data in the water quality dataset to obtain the maximum and minimum values;

[0074] Perform standardization processing on the data value x of each water quality data through Formula 1 to obtain the standardized data value , and Formula 1 is , and finally form a water quality data matrix.

[0075] Through the above steps, the accuracy and availability of the water quality monitoring data are improved. By standardization processing, data consistency and comparability are ensured. Standardization processing not only makes the data from different pump houses comparable but also enhances the sensitivity of the model to water quality changes, thereby improving the ability of the water quality monitoring system to identify potential pollution.

[0076] Preferably, based on the water quality data of some pump houses, analyze whether there is pollution in the water quality. If there is, feedback the analysis result to the pollution area analysis module; if not, directly feedback the analysis result, including the following steps:

[0077] Construct a rule set, where each rule corresponds to a feature, and the rule form is: If the feature value is greater than the threshold, it is considered that the water quality index represented by this feature is polluted;

[0078] Apply the following rules to the water quality data matrix fed back by the selected water quality data acquisition module and output the analysis result, where, represents the logical "OR", represents the data value of the j-th water quality characteristic of the i-th pump house, represents the threshold value of the j-th water quality characteristic.

[0079] Through the above steps, it is possible to accurately analyze and identify the pump houses with water quality pollution, improving the efficiency and accuracy of water quality monitoring. By constructing a rule set, each rule sets a threshold for a water quality characteristic. When the water quality characteristic value exceeds the threshold, the system determines that the water quality index represented by this characteristic is polluted. The system applies the collected water quality data matrix to these rules, combines the comparison results of the water quality characteristic data values of each pump house and the corresponding thresholds through the logical "OR" operator, and outputs the analysis result. This method enables the system to quickly respond to water quality changes. Once signs of pollution are detected, the analysis result is immediately fed back to the pollution area analysis module, so as to take corresponding measures.

[0080] Preferably, the method for establishing a prediction model includes the following steps,

[0081] Collect the historical water quality data of all pump houses in a certain area to form a map library containing polluted pump houses, and require that there is at least one pump house with water quality pollution during the same period;

[0082] Record the pollution degree of the water quality data of each pump house compared with the threshold value at the same time, and associate it with the color in the map. The pollution degree is proportional to the color;

[0083] For each pumping station, extract its water quality data as a feature vector: ;

[0084] Extract the color information of each pumping station from the map as a feature vector: ;

[0085] Use the cosine similarity to calculate the water quality feature similarity between two pumping stations: , where, is the dot product of the feature vectors, and are the norms of the vectors;

[0086] For the pumping stations with known pollution, use the water quality characteristics and color characteristics to train the model, and mark the polluted pumping stations as 1 and the non-polluted pumping stations as 0;

[0087] Import the support vector machine for training to find the optimal hyperplane to classify whether the pumping station is polluted, and finally output the prediction model;

[0088] According to the analysis result of the water quality safety analysis module and through the prediction model, analyze and confirm the pump houses that may be polluted, including the following steps,

[0089] Convert the pump house collected by the water quality data acquisition module into a real-time atlas, and extract the water quality data of the pump house collected by the water quality data acquisition module;

[0090] Extract features from the real-time atlas and the water quality data of the pump house collected by the water quality data acquisition module;

[0091] Import the above features into the prediction model and output the atlas of the historical water quality data of all pump houses in the same area at a certain period with the highest similarity;

[0092] Combine the output atlas to export the historical water quality data of the remaining uncollected pump houses to confirm the pump houses that may be polluted.

[0093] Collect and analyze the historical water quality data of all pump houses in the same area. By associating the water quality data with the color information in the atlas, construct a feature vector, and use the cosine similarity calculation method to evaluate the water quality feature similarity between pump stations. Subsequently, through the support vector machine training model, find the optimal hyperplane for distinguishing polluted and non-polluted pump houses, so as to establish a prediction model. Using this prediction model, by extracting the features of the real-time collected water quality data and historical data, import them into the prediction model for analysis to determine the pump houses that may be polluted. This step involves converting the real-time water quality data into an atlas, extracting features, and comparing them with historical data to identify and warn of potential water quality problems. In this way, all pump houses can jointly apply the same set of water quality monitoring systems, which can not only monitor the water quality in real time, but also discover and respond to possible water quality pollution events in advance through the prediction model, thus ensuring the safety of water supply.

[0094] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
