[0017] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings required for describing the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other accompanying drawings can be obtained based on these accompanying drawings without paying creative work.

[0018] 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

[0019] 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.

[0020] See also Figure 1 As shown, the present invention is a water supply management system of a self-generated ultrasonic remote water meter, comprising: Remote transmission module, used to send real-time user water volume data signals to a remote water supply control center through wireless communication technology; 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 user's water consumption changes meet the standard threshold: If yes, 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; 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; The judgment module is used to judge whether the user's water use is abnormal according to the user's water use level information, and generate a second warning signal and suspend water supply processing.

[0021] In the above technical scheme, in this embodiment, four modules are designed to realize the construction of the water supply management system of the self-generating ultrasonic remote water meter. Through the specific collection and intelligent analysis process of the user's water usage, 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.

[0022] Specifically, first, a remote transmission module is set 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, ensures the accuracy of data transmission during remote transmission, reduces data loss and guarantees signal strength. Usually, the remote transmission module not only supports 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 ensures 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.

[0023] Secondly, the water supply module is set to control the water supply selection based on the real-time user water volume data. Specifically, it ensures that specific water supply settings are generated according to user needs by coordinating the automatic water supply strategy, and the water supply strategy is pre-set according to different water use scenarios, user types (such as residential users, industrial users) and seasons. The water supply module performs multi-dimensional data analysis on the real-time user water volume data to determine the user's water use habits and seasonal characteristics, and then analyzes and calculates the user's water use rhythm coefficient, so as to start the automatic water supply strategy to accurately control the water supply meter and ensure the user's 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 areas with water shortages. 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 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, so as to achieve water energy optimization and regulation process.

[0024] Next, a monitoring module is set up to monitor the user's water use under the control of the automatic water supply strategy, and the user's water use changes within the target time period are obtained to determine the user's water use level, so as to facilitate the subsequent settlement of the user's 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 consumes a large amount of system computing power for the user's water use mining process. This design directly screens out water use abnormalities only through the analysis of the water use level information acquisition method, so as to quickly identify abnormal user water use situations and notify and process them in time.

[0025] Finally, the judgment module is set to judge whether there is unreasonable water use by the user through the user water use level information obtained by the monitoring module, and then judge the specific abnormal information, and generate the second warning signal and suspend water supply processing. It is usually necessary to judge the abnormal degree of user water use in a timely manner according to the range and frequency of abnormal information changes; for example, water use abnormalities are divided into minor abnormalities (such as water consumption is slightly higher than usual, but within a reasonable fluctuation range), moderate abnormalities (such as water consumption suddenly increases and exceeds the normal fluctuation range, but does not reach a serious degree) and severe abnormalities (such as water consumption continues to be abnormally high in a short period of time, there may be serious water leakage or water theft). Different levels of abnormalities correspond to different processing measures. Minor abnormalities may only require a signal reminder notification, while severe abnormalities require immediate water outage inspection and other measures.

[0026] As an embodiment of the present invention, the water supply module includes a time-varying analysis of the user's water consumption changes: Obtain a change curve A of the real-time user water use rhythm coefficient over a period of time; Obtain the change curve B of the historical user water use rhythm coefficient in the same time period; Construct the change curve A and the change curve B in the same coordinate system, and obtain the overlap area S of A and B; The overlap area S is compared with the preset standard area threshold S ’ To compare: If S ≥ S ’ , it is judged that the user's water consumption changes meet the requirements; If S<S ’ , it is judged that the user's water consumption changes do not meet the requirements.

[0027] Identify periodicities and trends in customer water usage, for example, analyzing customer water usage patterns over a day, week, or month.

[0028] In the above technical solution, in order to better understand and predict the user's water use behavior, so as to optimize the operation and management of the water supply system, the water supply module is set to analyze the time series of the user's water use changes. Specifically, first, by obtaining the change curve A of the time period of the real-time user's water use rhythm coefficient, and by obtaining the change curve B of the historical water use rhythm coefficient in the same time period; then by comparing the difference between the two curves A and B: 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 comparison overlap area S reflects the change of the user's water use rhythm coefficient, and ensures that the change of the user's water use habits is reasonable by judging the change range of the user's water use rhythm coefficient; usually, the user's water use rhythm coefficient is obtained by identifying the periodic changes and water use trends of the user's water use. The usual cycle is to analyze the user's water use pattern in one day, one week, one month or even one quarter. The water supply department can optimize the water supply scheduling to ensure that there is sufficient water supply capacity during peak demand. Through the analysis process of changes in user water use, it can help the water supply department to allocate resources more effectively, improve the efficiency of the water supply system, reduce waste, and ensure the quality and safety of water supply.

[0029] As an implementation mode of the present invention, the user's water use rhythm coefficient is obtained in the following manner: By formula Calculate the user's Cycle No. Water use rhythm coefficient at each time ; in, For the Cycle No. The preset weight coefficient at the moment, and Greater than 0; is a 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 moments corresponding to the ≤ .

[0030] 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 time ; According to the set water supply cycle time period, the real-time water consumption changes are carried out, and the real-time water consumption changes in each cycle are divided according to the set number of cycles, and the real-time water consumption rhythm coefficient of the user is obtained to take into account the impact of different periodicities on water consumption changes; the specific process of analysis is: 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 setting of Cycle No. The weight coefficient of the moment To set the size of the result value; it needs to be explained that the preset correlation function It is used to analyze the relationship between data at different time points in the periodic setting analysis and quantification; therefore, in the water use rhythm analysis of this design, the partial autocorrelation function PACF is usually used. The partial autocorrelation function PACF can help determine the order of the autoregressive model and then identify the periodic pattern in the water consumption data. If PACF has a significant non-zero value at certain k values, this may indicate that there is a periodic pattern in water consumption with a period of k. Combining it with ACF can more comprehensively analyze the periodic characteristics in the water use rhythm.

[0031] As an implementation mode of the present invention, the remote water supply control center starts the automatic water supply strategy in the following manner: The sensor collects the initialization data of water level, water pressure and flow of the water supply module; According to the change curve of the user's water use rhythm coefficient, the water supply cycle, water supply frequency and water supply interval duration are periodically set; Execute the automatic water supply program and obtain the user's water consumption unit cycle change, water use duration unit cycle change, and water use frequency unit cycle interval change.

[0032] In the above technical scheme, the remote control center in this embodiment starts the automatic water supply strategy based on the periodicity of the change curve of the user's water use rhythm coefficient; including setting the water supply cycle of 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. According to the operation process, the unit cycle change of water consumption of different users, the unit cycle change of water use duration, and the unit cycle interval change of water use frequency are obtained to reflect the changes in user water use.

[0033] As an implementation mode of the present invention, the method for the monitoring module to obtain the user's water use situation within a preset time period under the automatic water supply strategy for monitoring and analysis is: By formula Calculate the user's Information coefficient of water use level in each cycle ; 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 cycle per unit period, For the The change in water consumption per cycle per unit cycle; For the The change in the water use frequency per unit cycle; is the change in standard water consumption per unit period, is the change in standard water use duration per unit period; is the change in the standard water use frequency per unit cycle interval; For the Seasonal water use impact coefficient for a cycle.

[0034] In the above technical solution, the actual change of the user's water consumption is obtained by monitoring and analyzing through the monitoring module, specifically through the formula Calculate the user's Information coefficient of water use level in each cycle ; Due to the different water usage ranges under different users' water use rhythms, the user rhythm situation reflects the actual conditions of different users, such as the user population composition, composition structure, user living water use habits, etc.; based on the existing user water use 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 ensure timely water supply and water use management.

[0035] It should be explained that the standard value , , It is obtained based on historical experience, with preset weight coefficients , , The settings are pre-fitted based on historical experience data and will not be described in detail here; Seasonal water use impact coefficient for each cycle The correlation coefficient for each cycle is set according to the user's water consumption, which causes different degrees of fluctuation in water consumption due to the influence of different seasonal conditions.

[0036] As an embodiment of the present invention, Information coefficient of user water use level in a period Information coefficient threshold interval with standard user water use level To compare: like < , then determine the current user The water use level in each cycle is low; like , then determine the current user The water usage level for each cycle is normal; like > , then determine the current user The water usage level in a cycle is too high and there is abnormal water usage, generating a second warning signal.

[0037] 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 a water usage disclosure. If they are 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 beyond this range, it is judged that there may be abnormal water use, and specific analysis and judgment are required for the high water use level, and options are chosen to remind or suspend water supply.

[0038] As an implementation mode 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: 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 on the unit water supply volume under the pre-set water supply cycle, water supply frequency and water supply interval duration of the automatic water supply strategy.

[0039] The self-generated ultrasonic remote transmission water meter of the present invention serves the water supply management system of the self-generated ultrasonic remote transmission water meter. The self-generated ultrasonic remote transmission water meter includes: A measuring module, used to obtain real-time user water volume data signals through ultrasonic sensors, and transmit the real-time user water volume data signals through wireless communication circuits to convert them into remote transmission modules; A power module, used to provide kinetic energy to the water meter through a self-generating device; Display module, used for displaying water meter readings; A wireless communication module is used to wirelessly transmit the real-time user water volume data obtained by water meter measurement to the remote water supply control center of the water supply module through the remote transmission module; The outer shell and connecting parts are used to protect the internal components of the water meter and provide an interface for connecting to the water pipe.

[0040] In the above technical solution, the specific process of each part of the self-generated ultrasonic remote water meter is as follows: the measurement module of the self-generated ultrasonic remote water meter obtains the real-time user water volume data signal through the ultrasonic sensor, transmits it through the wireless communication circuit and converts it to the remote transmission module. The ultrasonic sensor calculates the flow rate and flow of water based on the time difference when the ultrasonic wave propagates downstream and upstream in the water. The power module provides kinetic energy to the water meter through the self-generated device. For example, some water meters use water flow to drive the turbine to rotate, and generate induced electromotive force through the permanent magnet and induction coil on the turbine to charge the battery. This self-generated mechanism can ensure that the water meter continues to work without an external power supply, ensuring energy conservation.

[0041] The display module is used to display the water meter readings, and it is convenient for users to directly view the water consumption through LED displays. The display module usually works in conjunction with the measurement module and the power module to ensure the accuracy of the data and the normal operation of the water meter. The wireless communication module transmits 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. This module usually supports multiple wireless communication protocols, such as GPRS, LoRa or NB-IoT, to ensure that the data can be transmitted to the remote control center safely and stably. The housing and connecting parts are used to protect the internal components of the water meter and provide interfaces for connection with the water pipe. These components need to have good sealing and durability to ensure that the water meter can work normally under various environmental conditions. The water supply management system runs in the remote water supply control center. It receives data from the self-generated ultrasonic remote water meter and starts the automatic water supply strategy based on this data; the water supply management system can automatically adjust the water supply strategy according to the actual water demand of the user to achieve efficient and energy-saving water supply services.

[0042] In summary, the realization of the automatic water supply function of the self-generated ultrasonic remote water meter requires the coordinated work of the various components of the water meter itself, and also requires the support of the water supply management system. In this way, efficient and accurate water supply services can be achieved, and the utilization efficiency of water resources can also be improved.
