DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0021] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0022] Please refer to Figure 1 , Figure 1 This is a flow chart of a smart water meter reporting method based on flow change in some embodiments of the present application. The smart water meter reporting method based on flow change is used in a terminal device, and the smart water meter reporting method based on flow change includes the following steps: S101, setting a regular reporting cycle, setting a number of interruption time nodes based on the regular reporting cycle, and collecting a number of corresponding water meter collection data based on the interruption time nodes; S102, analyzing water meter flow data corresponding to a number of interruption time nodes based on water meter collection data, and generating water meter flow change information of adjacent interruption time nodes based on the water meter flow data corresponding to the interruption time nodes; S103, determining whether the water meter flow change information at adjacent interruption time nodes is greater than or equal to a set flow increment threshold; S104, if it is greater than or equal to, generating water meter flow change information, encrypting the water meter flow change information and transmitting it to the terminal; S105: If it is less than, the flow change is determined to be normal, the monitoring strategy is switched, and the water meter flow change information is monitored again in the next scheduled reporting cycle.

[0023] It should be noted that by setting the reporting cycle to collect water meter flow data intermittently, the water meter flow change information at different interruption time nodes can be determined. When the flow change information of two adjacent interruption time nodes is greater than the set flow increment threshold, it indicates that the flow change is abnormal, and the abnormal data is transmitted to the terminal, and the abnormal time node is recorded for maintenance reporting.

[0024] Please refer to Figure 2 , Figure 2 The present invention is a flow chart of a method for acquiring water meter data collection based on a flow change-based smart water meter reporting method in some embodiments of the present application. According to an embodiment of the present invention, a timed reporting cycle is set, a number of interruption time nodes are set based on the timed reporting cycle, and a number of corresponding water meter data are collected based on the interruption time nodes, specifically including: S201, set a scheduled reporting period, where the scheduled reporting period includes 1 hour, 1 day or 1 week; S202, setting a divided time period, dividing the scheduled reporting cycle into equal time periods based on the divided time periods, and generating a number of interruption time nodes; S203, generating a corresponding acquisition signal at each interruption time node; S204, collecting water meter data at each interruption time node based on the collection signal.

[0025] It should be noted that the time periods are divided according to the set scheduled reporting cycle. For example, if the scheduled reporting cycle is 1 hour, the divided time periods are set to 10 minutes or 20 minutes, thereby dividing the 1-hour scheduled reporting cycle into multiple interruption time nodes. If the scheduled reporting cycle is 1 day, the divided time periods are set to 1 hour or 2 hours. If the scheduled reporting cycle is 1 week, the divided time periods are set to 12 hours, thereby establishing the divided time periods of different scheduled reporting cycles, obtaining the corresponding interruption time nodes, and collecting water meter data in different time periods according to different interruption time nodes.

[0026] Furthermore, the setting of the periodic reporting cycle may be considered to be set according to the type of water meter, or the water flow rate, or user demand information.

[0027] For example, for a water flow with a high velocity, the period is shorter, and for a water flow with a low velocity, the period is longer.

[0028] For dividing time periods, some other dynamic adjustment schemes may be considered.

[0029] Dynamically adjust the time periods within each scheduled reporting cycle based on traffic changes that trigger reporting.

[0030] For example, when the trigger reporting frequency is high, the divided time period may be set shorter; and when the trigger reporting frequency is low, the divided time period may be set longer.

[0031] For example, for a certain day, 24 time periods are divided, corresponding to 24 interruption time nodes; if traffic change information is reported at more than 12 interruption time points, it means that the frequency is high, and every 2 hours can be set as an interruption time node, that is, 12 time periods are divided.

[0032] Furthermore, the time period division may not be equal to the time period division, and multiple interruption time points may be determined directly in one timing reporting cycle.

[0033] Please refer to Figure 3 , Figure 3 The flow chart of a method for obtaining water meter flow data based on a flow change reporting method of a smart water meter in some embodiments of the present application is as follows. According to an embodiment of the present invention, analyzing water meter flow data corresponding to a plurality of interruption time nodes based on water meter collection data specifically includes: S301, acquiring a collected signal, extracting signal features, and comparing the signal features with a set feature interval; S302, determining whether the signal feature is within a set feature interval; S303, if it is, obtain the water meter flow data corresponding to the interruption time node; S304, if not, obtain signal feature distribution, obtain noise features based on signal feature distribution analysis, remove the noise features, and obtain a collected signal after noise removal; S305, collecting water meter flow based on the collected signal after noise removal, and obtaining water meter flow data corresponding to the interruption time node.

[0034] It should be noted that the collected signal is subjected to feature extraction and analysis to eliminate invalid features, thereby eliminating noise signals and ensuring the accuracy of the collected signal. In this way, accurate water meter flow data can be collected based on the collected signal, reducing data fluctuations during the flow collection process and improving the stability of data collection.

[0035] According to an embodiment of the present invention, generating water meter flow change information of adjacent interruption time nodes based on water meter flow data corresponding to the interruption time node specifically includes: Obtain water meter flow data at adjacent interruption time nodes, perform difference calculation on the water meter flow data at adjacent time nodes, and obtain flow difference; Determine whether the flow difference is greater than or equal to a set flow difference threshold; If it is less than, flow fluctuation information is generated; If it is greater than or equal to, the water meter flow change information is calculated based on the flow difference.

[0036] It should be noted that by analyzing the water meter flow data of adjacent time nodes to calculate the flow difference and analyze the flow fluctuation information, when the flow in adjacent interruption time nodes is less than the set flow difference threshold, it means that the flow has only fluctuated to a certain extent and has not caused a large change, and it will not be recorded as a flow change, thereby accurately obtaining the water meter flow change information.

[0037] According to an embodiment of the present invention, if it is greater than or equal to, water meter flow change information is generated, and the water meter flow change information is encrypted and transmitted to the terminal, specifically including: Obtaining traffic change information, generating encryption parameters based on the traffic change information, and generating corresponding encryption keys based on the encryption parameters; Encrypt the traffic change information based on the encryption key to generate ciphertext data; Upload the encrypted data to the terminal according to the predetermined transmission method and transmission channel; A matching decryption key is established based on the encryption key, and the decryption key is saved to the terminal.

[0038] It should be noted that by establishing an encryption key to encrypt the traffic change information for transmission, the security of data transmission is improved. At the same time, a matching decryption key is generated synchronously during the encryption process. When the data needs to be called, the encrypted ciphertext data is reversely parsed using the decryption key to obtain accurate traffic change data.

[0039] Furthermore, the water meter location or user contact information is sent at the same time as the flow change information so that maintenance personnel can arrive at the site in time. By communicating with the ground cellular network through satellite communication, the problem of IoT water meters being unable to report because they are installed in some remote areas without cellular network coverage can be avoided.

[0040] Specifically, in order to protect the privacy of user data, it is possible to consider combining zero-knowledge proof or quantum key or blockchain, so that encryption keys and decryption keys can be stored in different blocks to improve the security of user data.

[0041] According to an embodiment of the present invention, if it is less than, the flow change is determined to be normal, the monitoring strategy is switched, and the water meter flow change information is monitored again in the next scheduled reporting cycle, specifically including: If the water meter flow change information at the adjacent interruption time nodes is less than the set flow increment threshold, the flow change is determined to be normal and adjustment information is generated; Adjust the divided time period based on the adjustment information to generate a new divided time period; Based on the new divided time period, the scheduled reporting cycle is divided again to generate a new interruption time node; Based on the new interruption time node, the water meter flow change information is monitored again.

[0042] It should be noted that by analyzing the water meter flow change information at adjacent time nodes, when the flow change is normal, it is not possible to accurately judge that the water meter flow is normal. Therefore, the time period is adjusted. For example, the time period is set from 10 minutes or 20 minutes to 5 minutes, the collection interval is reduced, and the collected data is judged again to improve the analysis accuracy of the water meter flow change.

[0043] According to an embodiment of the present invention, it also includes: setting a timed interruption and a timed reporting period (1 hour to 10 days), and the timed reporting period can be modified through the platform.

[0044] The timer interrupt starts the scheduled data reporting, extracts the current flow, the previous three scheduled reported flows and the recent 24-hour hourly flow, encrypts the current time and the extracted flow data, and reports the data through the Internet of Things module; Monitor traffic data. If the traffic data reaches the traffic increment threshold, extract the current time data, current traffic volume, and the previous three traffic change times, and encrypt the current time, extracted traffic, and time data.

[0045] It should be noted that by collecting water meter flow at regular intervals and analyzing flow changes, encrypted transmission is performed, network fluctuation information is analyzed during encrypted transmission, and the time delay in the data transmission process is analyzed based on the network fluctuation information, thereby analyzing the missing data and filling in the missing data to improve the accuracy of the transmitted data.

[0046] In a second aspect, an embodiment of the present application provides a smart water meter reporting system based on flow changes, the system comprising: a memory and a processor, the memory comprising a program of a smart water meter reporting method based on flow changes, and the program of the smart water meter reporting method based on flow changes is executed by the processor to implement the following steps: Set a scheduled reporting cycle, set a number of interruption time nodes based on the scheduled reporting cycle, and collect a number of corresponding water meter collection data based on the interruption time nodes; Analyze the water meter flow data corresponding to several interruption time nodes based on the water meter collection data, and generate water meter flow change information of adjacent interruption time nodes based on the water meter flow data corresponding to the interruption time nodes; Determine whether the water meter flow change information at adjacent interruption time nodes is greater than or equal to the set flow increment threshold; If it is greater than or equal to, water meter flow change information is generated, encrypted and transmitted to the terminal; If it is less than, the flow change is determined to be normal, the monitoring strategy is switched, and the water meter flow change information is monitored again in the next scheduled reporting cycle.

[0047] It should be noted that by setting the reporting cycle to collect water meter flow data intermittently, the water meter flow change information at different interruption time nodes can be determined. When the flow change information of two adjacent interruption time nodes is greater than the set flow increment threshold, it indicates that the flow change is abnormal, and the abnormal data is transmitted to the terminal, and the abnormal time node is recorded for maintenance reporting.

[0048] According to an embodiment of the present invention, a regular reporting cycle is set, a number of interruption time nodes are set based on the regular reporting cycle, and a number of corresponding water meter collection data are collected based on the interruption time nodes, specifically including: Set a scheduled reporting period, which includes 1 hour, 1 day or 1 week; Set the time period, divide the scheduled reporting cycle into equal time periods based on the time period, and generate several interruption time nodes; Each interrupt time node generates a corresponding acquisition signal; The water meter data is collected at each interruption time node based on the collected signal.

[0049] It should be noted that the time periods are divided according to the set scheduled reporting cycle. For example, if the scheduled reporting cycle is 1 hour, the divided time periods are set to 10 minutes or 20 minutes, thereby dividing the 1-hour scheduled reporting cycle into multiple interruption time nodes. If the scheduled reporting cycle is 1 day, the divided time periods are set to 1 hour or 2 hours. If the scheduled reporting cycle is 1 week, the divided time periods are set to 12 hours, thereby establishing the divided time periods of different scheduled reporting cycles, obtaining the corresponding interruption time nodes, and collecting water meter data in different time periods according to different interruption time nodes.

[0050] Furthermore, the setting of the periodic reporting cycle may be considered to be set according to the type of water meter, or the water flow rate, or user demand information.

[0051] For example, for a water flow with a high velocity, the period is shorter, and for a water flow with a low velocity, the period is longer.

[0052] For dividing time periods, some other dynamic adjustment schemes may be considered.

[0053] Dynamically adjust the time periods within each scheduled reporting cycle based on traffic changes that trigger reporting.

[0054] For example, when the trigger reporting frequency is high, the divided time period may be set shorter; and when the trigger reporting frequency is low, the divided time period may be set longer.

[0055] For example, for a certain day, 24 time periods are divided, corresponding to 24 interruption time nodes; if traffic change information is reported at more than 12 interruption time points, it means that the frequency is high, and every 2 hours can be set as an interruption time node, that is, 12 time periods are divided.

[0056] Furthermore, the time period division may not be equal to the time period division, and multiple interruption time points may be determined directly in one timing reporting cycle.

[0057] According to an embodiment of the present invention, analyzing water meter flow data corresponding to a number of interruption time nodes based on water meter collection data specifically includes: Acquire the collected signal, extract the signal features, and compare the signal features with the set feature interval; Determine whether the signal characteristics are within the set characteristic interval; If it is, the water meter flow data corresponding to the interruption time node is obtained; If not, obtain the signal feature distribution, obtain the noise feature based on the signal feature distribution analysis, remove the noise feature, and obtain the collected signal after the noise is removed; The water meter flow is collected based on the collected signal after noise removal to obtain the water meter flow data corresponding to the interruption time node.

[0058] It should be noted that the collected signal is subjected to feature extraction and analysis to eliminate invalid features, thereby eliminating noise signals and ensuring the accuracy of the collected signal. In this way, accurate water meter flow data can be collected based on the collected signal, reducing data fluctuations during the flow collection process and improving the stability of data collection.

[0059] According to an embodiment of the present invention, generating water meter flow change information of adjacent interruption time nodes based on water meter flow data corresponding to the interruption time node specifically includes: Obtain water meter flow data at adjacent interruption time nodes, perform difference calculation on the water meter flow data at adjacent time nodes, and obtain flow difference; Determine whether the flow difference is greater than or equal to a set flow difference threshold; If it is less than, flow fluctuation information is generated; If it is greater than or equal to, the water meter flow change information is calculated based on the flow difference.

[0060] It should be noted that by analyzing the water meter flow data of adjacent time nodes to calculate the flow difference and analyze the flow fluctuation information, when the flow in adjacent interruption time nodes is less than the set flow difference threshold, it means that the flow has only fluctuated to a certain extent and has not caused a large change, and it will not be recorded as a flow change, thereby accurately obtaining the water meter flow change information.

[0061] According to an embodiment of the present invention, if it is greater than or equal to, water meter flow change information is generated, and the water meter flow change information is encrypted and transmitted to the terminal, specifically including: Obtaining traffic change information, generating encryption parameters based on the traffic change information, and generating corresponding encryption keys based on the encryption parameters; Encrypt the traffic change information based on the encryption key to generate ciphertext data; Upload the encrypted data to the terminal according to the predetermined transmission method and transmission channel; A matching decryption key is established based on the encryption key, and the decryption key is saved to the terminal.

[0062] It should be noted that by establishing an encryption key to encrypt the traffic change information for transmission, the security of data transmission is improved. At the same time, a matching decryption key is generated synchronously during the encryption process. When the data needs to be called, the encrypted ciphertext data is reversely parsed using the decryption key to obtain accurate traffic change data.

[0063] Furthermore, the water meter location or user contact information is sent at the same time as the flow change information so that maintenance personnel can arrive at the site in time. By communicating with the ground cellular network through satellite communication, the problem of IoT water meters being unable to report because they are installed in some remote areas without cellular network coverage can be avoided.

[0064] Specifically, in order to protect the privacy of user data, it is possible to consider combining zero-knowledge proof or quantum key or blockchain, so that encryption keys and decryption keys can be stored in different blocks to improve the security of user data.

[0065] According to an embodiment of the present invention, if it is less than, the flow change is determined to be normal, the monitoring strategy is switched, and the water meter flow change information is monitored again in the next scheduled reporting cycle, specifically including: If the water meter flow change information at the adjacent interruption time nodes is less than the set flow increment threshold, the flow change is determined to be normal and adjustment information is generated; Adjust the divided time period based on the adjustment information to generate a new divided time period; Based on the new divided time period, the scheduled reporting cycle is divided again to generate a new interruption time node; Based on the new interruption time node, the water meter flow change information is monitored again.

[0066] It should be noted that by analyzing the water meter flow change information at adjacent time nodes, when the flow change is normal, it is not possible to accurately judge that the water meter flow is normal. Therefore, the time period is adjusted. For example, the time period is set from 10 minutes or 20 minutes to 5 minutes, the collection interval is reduced, and the collected data is judged again to improve the analysis accuracy of the water meter flow change.

[0067] According to an embodiment of the present invention, it also includes: setting a timed interruption and a timed reporting period (1 hour to 10 days), and the timed reporting period can be modified through the platform.

[0068] The timer interrupt starts the scheduled data reporting, extracts the current flow, the previous three scheduled reported flows and the recent historical 24-hour hourly flow, encrypts the current time and the extracted flow data, and reports the data through the Internet of Things module; Monitor traffic data. If the traffic data reaches the traffic increment threshold, extract the current time data, current traffic volume, and the previous three traffic change times, and encrypt the current time, extracted traffic, and time data.

[0069] It should be noted that by collecting water meter flow at regular intervals and analyzing flow changes, encrypted transmission is performed, network fluctuation information is analyzed during encrypted transmission, and the time delay in the data transmission process is analyzed based on the network fluctuation information, thereby analyzing the missing data and filling in the missing data to improve the accuracy of the transmitted data.

[0070] A third aspect of the present invention provides a computer-readable storage medium, which includes a smart water meter reporting method program based on flow changes. When the smart water meter reporting method program based on flow changes is executed by a processor, the steps of the smart water meter reporting method based on flow changes as described in any one of the above items are implemented.

[0071] The present invention discloses a smart water meter reporting method, system and medium based on flow change, which comprises the following steps: setting a timed reporting cycle, setting a number of interruption time nodes based on the timed reporting cycle, collecting a number of corresponding water meter collection data based on the interruption time nodes; analyzing the water meter flow data corresponding to the number of interruption time nodes based on the water meter collection data, generating water meter flow change information of adjacent interruption time nodes based on the water meter flow data corresponding to the interruption time nodes; judging whether the water meter flow change information of adjacent interruption time nodes is greater than or equal to a set flow increment threshold; if greater than or equal to, generating water meter flow change information, encrypting the water meter flow change information and transmitting it to a terminal; if less than, judging that the flow change is normal, switching the monitoring strategy, and monitoring the water meter flow change information again in the next timed reporting cycle; triggering the reporting mechanism by a method of timing combined with flow change, and then encrypting the data before reporting the data to the platform, thereby improving the security of the reported data; being able to report data in real time when the flow changes, and providing a water service platform with reliable flow increase time and flow; and being able to provide the water service platform with complete data when the network is unstable or fails. It is particularly suitable for use in scenarios of on-site operation and maintenance of smart water services, providing effective data for water management losses and water meter error inspection.

[0072] In the several embodiments provided in the present application, it should be understood that the disclosed devices and methods can be implemented in other ways.
