[0048] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for describing the embodiments. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0049] Figure 1 This is a module diagram of the water supply management system of the self-generated ultrasonic remote transmission water meter of the present invention. DETAILED DESCRIPTION

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0051] See also Figure 1 As shown, the present invention is a water supply management system for a self-generated ultrasonic remote water meter, comprising:

[0052] Remote transmission module, used to send real-time user water volume data signals to the remote water supply control center through wireless communication technology;

[0053] The water supply module is used to perform multi-dimensional data analysis based on real-time user water volume data signals to determine whether the changes in user water consumption meet the standard threshold:

[0054] If so, the user's water consumption rhythm coefficient is obtained, and the remote water supply control center starts the automatic water supply strategy;

[0055] If not, the water supply is restricted and the first warning signal is activated;

[0056] A monitoring module is used to monitor and analyze the user's water consumption within a preset time period under the control of the automatic water supply strategy, and obtain the user's water consumption level information within the preset time period;

[0057] The judgment module is used to judge whether the user's water use is abnormal based on the user's water use level information, and generate a second warning signal and suspend water supply processing.

[0058] In the above technical solution, in this embodiment, the water supply management system of the self-generating ultrasonic remote water meter is constructed by designing four modules. Through the specific collection and intelligent analysis process of the user's water usage situation, the automatic water supply regulation and water energy optimization regulation of the self-generating ultrasonic remote water meter water supply management system are strengthened, so as to save water resources and optimize the user's water supply process.

[0059] Specifically, first, a remote transmission module is set up to realize the digital transmission process of user water volume information through wireless signal transmission technology, and remotely transmit the received user water volume data signal to the remote water supply control; therefore, the remote transmission module has the security function of information remote transmission, ensuring the accuracy of data transmission during remote transmission, reducing data loss and signal strength. Usually, the remote transmission module not only needs to support common wireless communication technologies such as GPRS, LoRa or NB-IoT, but also has a communication protocol adaptation function to ensure a safe data transmission process, and ensure that it can automatically identify and adapt to different network environments and communication protocols required by the receiving end; the remote transmission module also has data encryption and compression processes and signal strength monitoring and adaptive adjustment. The remote transmission module has a built-in signal strength monitoring function, which can monitor the signal strength of wireless communication in real time. When the signal strength is lower than the set threshold, the module will automatically adjust the transmission power or switch the communication frequency band.

[0060] Next, the water supply module uses the real-time user water consumption data to control water supply selection. Specifically, it coordinates automatic water supply strategies to ensure that specific water supply settings are generated according to user needs. Water supply strategies are pre-set based on different water use scenarios, user types (such as residential users and industrial users), and seasonal factors. The water supply module performs multi-dimensional data analysis on real-time user water consumption data to determine user water habits and seasonal characteristics. It then analyzes and calculates the user water use rhythm coefficient, activates the automatic water supply strategy, and accurately controls the water supply meter to ensure basic water needs. The process of multidimensional data analysis is to determine whether the changes in user water use meet the preset standard threshold. If so, the user's water use rhythm coefficient is obtained, and the remote water supply control center starts the automatic water supply strategy; if not, the water supply is restricted and the first warning signal is activated; the pre-set standard threshold is used to ensure that the water use rhythm coefficient corresponding to the user's real-time water use habits is limited in advance. If it exceeds this normal range, a reminder is required to improve residents' awareness of environmental protection and water use, especially in water-scarce areas. Residents' water use requires certain restriction standards to achieve water conservation; if the water use status is normal, the designed automatic water supply strategy can be used to realize the automation process of water supply, reduce the computing power burden of subsequent monitoring of the water supply system, and reduce the pressure of personnel monitoring during continuous water supply, thereby realizing the water energy optimization and regulation process.

[0061] Next, a monitoring module is set up to monitor the user's water use under the control of the automatic water supply strategy, obtain the user's water use changes within the target time period to determine the user's water use level, so as to facilitate the subsequent settlement of user water consumption and timely equipment maintenance and replacement according to the frequency of use of the water meter equipment; the detection module in this embodiment is different from the conventional detection module in that it performs a large amount of big data management and fusion analysis on various information of user water use, and requires a large amount of system computing power to carry out the user water use mining process. This design only directly screens water use anomalies through the analysis of the water use level information acquisition method, so as to quickly identify user water use anomalies and notify them in time.

[0062] Finally, a judgment module is set up to determine whether there is any unreasonable user water use based on the user water level information obtained by the monitoring module, and then determine the specific abnormal information, generate a second warning signal, and suspend water supply. It is usually necessary to promptly determine the degree of abnormal user water use based on the range and frequency of changes in the abnormal information. For example, water use anomalies are divided into minor anomalies (such as water consumption slightly higher than usual, but within a reasonable fluctuation range), moderate anomalies (such as water consumption suddenly increases and exceeds the normal fluctuation range, but does not reach a serious level), and severe anomalies (such as water consumption is abnormally high for a short period of time, which may indicate serious water leakage or water theft). Different levels of anomalies correspond to different handling measures. Minor anomalies may only require a signal reminder notification, while severe anomalies require immediate measures such as water outage and inspection.

[0063] As an embodiment of the present invention, the water supply module includes a time-varying analysis of the user's water consumption changes:

[0064] Obtain the change curve A of the real-time user water use rhythm coefficient over a period of time;

[0065] Obtain the change curve B of the historical user water use rhythm coefficient in the same time period;

[0066] Construct the change curve A and the change curve B in the same coordinate system and obtain the overlapping area S of A and B;

[0067] The overlap area S is compared with the preset standard area threshold S ’ To compare:

[0068] If S≥S ’ , it is judged that the user's water consumption changes meet the requirements;

[0069] If S<S ’ , it is judged that the user's water consumption changes do not meet the requirements.

[0070] Identify periodicities and trends in customer water usage, for example, analyzing customer water usage patterns over a day, week, or month.

[0071] In the above technical solution, in order to better understand and predict user water use behavior and thus optimize the operation and management of the water supply system, a water supply module is set up to perform time series analysis on user water use changes. Specifically, a real-time user water use rhythm coefficient change curve A is obtained for each time period, and a historical water use rhythm coefficient change curve B is obtained for the same time period. Then, the difference between these two curves A and B is compared: the two change curves are established in the same coordinate system, and the overlap area S of the curves is compared. The size of the overlap area S reflects the change in the user's water use rhythm coefficient, ensuring that the change in the user's water use habits is reasonable based on the change range of the user's water use rhythm coefficient. The user's water use rhythm coefficient is usually obtained by identifying the periodic changes and water use trends of the user. The period is usually analyzed by analyzing the user's water use pattern over a day, week, month, or even a quarter. The water supply department can optimize water supply scheduling to ensure sufficient water supply capacity during peak demand periods. By analyzing the changes in user water use, the water supply department can help allocate resources more effectively, improve the efficiency of the water supply system, reduce waste, and ensure the quality and safety of the water supply.

[0072] As an embodiment of the present invention, the user's water use rhythm coefficient is obtained in the following manner:

[0073] By formula Calculate the user's Cycle No. Water use rhythm coefficient at each moment ;

[0074] in, For the Cycle No. The preset weight coefficient at the moment, and greater than 0; is the preset correlation function; For the Cycle No. Water consumption at any given moment; is the total number of cycles, and ∈ ; For the current cycle The total number of water usage times corresponding to the ≤ .

[0075] In the above technical solution, the user's water rhythm coefficient is obtained by calculation. Specifically, the formula Calculate the user's Cycle No. Water use rhythm coefficient at each moment The real-time water consumption changes are analyzed within the set water supply cycle, and the real-time water consumption changes in each cycle are divided according to the set number of cycles. The user's real-time water consumption rhythm coefficient is obtained to take into account the impact of different periodicities on water consumption changes. The specific analysis process is as follows:

[0076] First obtain the Cycle No. Water consumption at any time ; Then calculate the current Total water consumption per cycle , and then calculate all cycles Total water consumption , by obtaining the real-time water use rhythm coefficient of the set cycle Since different cycle setting methods produce different water use rhythm coefficients, the first Cycle No. Weight coefficient of time To set the size of the result value; Among them, it needs to be explained that the preset correlation function The PACF is used to analyze the relationship between data at different time points in a cyclical setting. Therefore, in this design's water consumption rhythm analysis, the partial autocorrelation function (PACF) is often used. The PACF can help determine the order of the autoregressive model and, in turn, identify cyclical patterns in water consumption data. If the PACF has significant non-zero values ​​at certain k values, this may indicate a cyclical pattern in water consumption with a period of k. Combining this with the ACF can provide a more comprehensive analysis of the cyclical characteristics of water consumption rhythms.

[0077] As an embodiment of the present invention, the remote water supply control center starts the automatic water supply strategy in the following manner:

[0078] The sensor collects the initialization data of water level, water pressure and flow of the water supply module;

[0079] Periodically set the water supply cycle, water supply frequency and water supply interval duration according to the change curve of the user's water use rhythm coefficient;

[0080] Execute the automatic water supply program and obtain the user's water consumption per unit cycle change, water use duration per unit cycle change, and water use frequency per unit cycle interval change.

[0081] In the above technical solution, the remote control center in this embodiment starts the automatic water supply strategy based on the periodic change curve of the user's water use rhythm coefficient; including setting the water supply cycle for different users, the user's water supply frequency and the corresponding water supply interval duration; and starts the automatic water supply program. The set initial value of this program is based on the water supply cycle, the user's water supply frequency and the corresponding water supply interval duration, and obtains the unit cycle change of water consumption, the unit cycle change of water use duration and the unit cycle interval change of water use frequency of different users according to the operation process to reflect the changes in user water use.

[0082] As an embodiment of the present invention, the method for the monitoring module to obtain the user's water consumption within a preset time period under the automatic water supply strategy for monitoring and analysis is as follows:

[0083] By formula Calculate the user's Water use level information coefficient for each cycle ;

[0084] in, is the first preset weight coefficient, is the second preset weight coefficient, is the third preset weight coefficient; For the The change in water consumption per unit period, For the The change in water consumption per cycle; For the The change in water use frequency per unit cycle; is the change in standard water consumption per unit period, is the change in standard water usage time per unit cycle; is the change in the standard water use frequency per unit cycle interval; For the Seasonal water use impact coefficient for a cycle.

[0085] In the above technical solution, the method for obtaining the actual change of user water consumption in this embodiment is to monitor and analyze through the monitoring module, specifically through the formula Calculate the user's Water use level information coefficient for each cycle ; Since different users have different water usage ranges under their water usage rhythms, the user rhythm situation reflects the actual conditions of different users, such as the user population composition, composition structure, user living water habits, etc.; based on the existing user water usage rhythm, water use level classification is carried out, which can accurately obtain abnormal information on actual user water use; for users who exceed the actual water use level, information is checked to ensure faster discovery of abnormal situations and timely water supply and water use management.

[0086] It should be explained that the standard value 、 、 It is obtained based on historical experience and has a preset weight coefficient 、 、 The settings made in advance based on historical experience data will not be detailed here; Seasonal water use impact coefficient for each cycle The correlation coefficient for each cycle is set based on the degree of fluctuation in water consumption caused by the influence of different seasonal conditions on the user's water consumption.

[0087] As an embodiment of the present invention, User water use level information coefficient for each cycle Information coefficient threshold interval with standard user water use level To compare:

[0088] like < , then determine the current user's The water use level in each cycle is low;

[0089] like , then determine the current user's The water usage level for the cycle is normal;

[0090] like > , then determine the current user's The water usage level in each cycle is relatively high, indicating abnormal water usage, and a second warning signal is generated.

[0091] In the above technical solution, the user water use level information coefficient is compared and analyzed with the standard user water use level information coefficient threshold range. Compare the sizes. If they are within the interval range, it proves that they are within the normal water use level range. If they are lower than this interval range, it is judged that the user may have low water consumption. If the level is lower than the normal range for a long time, it is judged that the residents have not lived there for a period of time, and the specific management and maintenance will depend on the situation. For situations outside this range, it is judged that there may be abnormal water use, and specific analysis and judgment of the high water use level is required, and options include reminders or suspension of water supply.

[0092] As an embodiment of the present invention, the system further includes an adjustment module; the adjustment module generates automatic water supply strategy adjustment information according to the second warning signal:

[0093] By adjusting the operating frequency, start and stop time of the water pump, or adjusting the opening of the valve, it is possible to generate adjustment information for the unit water supply under the pre-set water supply cycle, water supply frequency and water supply interval duration of the automatic water supply strategy.

[0094] The self-generating ultrasonic remote transmission water meter of the present invention serves the water supply management system of the self-generating ultrasonic remote transmission water meter. The self-generating ultrasonic remote transmission water meter includes:

[0095] The measuring module is used to obtain the real-time user water volume data signal through the ultrasonic sensor, and transmit the real-time user water volume data signal through the wireless communication circuit to the remote transmission module;

[0096] A power module, used to provide kinetic energy to the water meter through a self-generating device;

[0097] Display module, used to display water meter readings;

[0098] The wireless communication module is used to wirelessly transmit the real-time user water volume data obtained by the water meter measurement to the remote water supply control center of the water supply module through the remote transmission module;

[0099] The outer shell and connecting parts are used to protect the internal components of the water meter and provide an interface for connection to the water pipe.

[0100] In the above technical solution, the specific processes of the self-generated ultrasonic remote water meter are as follows: The measurement module of the self-generated ultrasonic remote water meter uses an ultrasonic sensor to measure and obtain real-time user water consumption data signals, which are transmitted and converted to the remote transmission module via a wireless communication circuit. The ultrasonic sensor calculates the water flow rate and flow rate based on the time difference between the propagation of ultrasonic waves in the water upstream and downstream. The power module uses a self-generated device to provide kinetic energy to the water meter. For example, some water meters use the water flow to drive a turbine, generating an induced electromotive force through the permanent magnet and induction coil on the turbine, thereby charging the battery. This self-generated mechanism ensures that the water meter can operate continuously without an external power supply, ensuring energy conservation.

[0101] The display module displays water meter readings, allowing users to directly view water consumption through LED displays and other means. The display module typically works in conjunction with the measurement module and power module to ensure data accuracy and proper meter operation. The wireless communication module wirelessly transmits real-time user water consumption data obtained from the water meter via the remote transmission module to the remote water supply control center in the water supply module. This module typically supports multiple wireless communication protocols, such as GPRS, LoRa, or NB-IoT, ensuring secure and stable data transmission to the remote control center. The housing and connecting components protect the internal components of the water meter and provide interfaces for connection to the water pipes. These components must be well sealed and durable to ensure the meter's proper operation in various environmental conditions. The water supply management system, operating in the remote water supply control center, receives data from the self-generated ultrasonic remote transmission water meter and uses this data to initiate an automatic water supply strategy. The water supply management system can automatically adjust the water supply strategy based on actual user water demand, achieving efficient and energy-saving water supply services.

[0102] In summary, achieving the automatic water supply function of a self-generated ultrasonic remote water meter requires the coordinated operation of the meter's various components, as well as the support of a water supply management system. This approach enables efficient and accurate water supply services while also improving water resource utilization.
