Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figure 1 , a cold water meter remote verification system based on the Internet. The system consists of a cold water meter multi-dimensional data acquisition module, a cold water meter remote analysis module, a cold water meter verification and evaluation module, a cold water meter remote execution module, and an execution situation feedback and optimization module;

[0035] The multi-dimensional data acquisition module of the cold water meter is responsible for acquiring data in all directions. The multi-dimensional data acquisition module of the cold water meter includes a water meter self-data acquisition unit, a flow data acquisition unit, an environmental data acquisition unit, and a transmission performance data acquisition unit;

[0036] The remote analysis module of the cold water meter is used to calculate data. The remote analysis module of the cold water meter includes a water meter fault analysis unit, an environmental impact analysis unit, and a transmission efficiency analysis unit;

[0037] The calibration and evaluation module of the cold water meter reviews the calculation results of the remote analysis module, evaluates whether they meet the calibration standards, and decides whether to put them into use.

[0038] The water meter self-data acquisition unit acquires the water meter self-data through the basic information of the water meter manufacturer and sensor monitoring. The water meter self-data acquisition unit numbers the water meter display flow according to the water meter self-data characteristics, and the water meter display flow number is A.

[0039] The flow data acquisition unit acquires the user's water consumption data by online monitoring the water flow rate, instantaneous flow rate, and cumulative flow rate of the water meter. The flow data acquisition unit numbers the normal water temperature and water pressure of the user's water consumption according to the user's water consumption data characteristics, and the normal water temperature and water pressure of the user's water consumption are numbered as T and P respectively.

[0040] The environmental data acquisition unit acquires environmental data through sensors and monitoring devices, including environmental temperature, humidity, and electromagnetic interference intensity. These environmental factors are one of the problems affecting the normal operation and data transmission of the water meter. The environmental data acquisition unit numbers the water temperature deviation and water pressure deviation of the user's water consumption at the i-th moment under the comprehensive influence of environmental temperature, humidity, and electromagnetic interference intensity according to the environmental data characteristics. The water temperature deviation and water pressure deviation of the user's water consumption at the i-th moment under the comprehensive influence of environmental temperature, humidity, and electromagnetic interference intensity are numbered as Δt i and Δp i .

[0041] The transmission performance data acquisition unit acquires transmission performance data through the Iperf3 tool and Ping command, such as network bandwidth, latency, and packet loss rate, to ensure that the data can be stably and quickly transmitted to the remote analysis module of the cold water meter. The transmission performance data acquisition unit numbers the network bandwidth, network latency, and packet loss rate according to the transmission performance data characteristics, and the network bandwidth, network latency, and packet loss rate are numbered as L, H, and D respectively.

[0042] The water meter fault analysis unit calculates the water meter accuracy Ge according to the water meter self-data, and its calculation formula is:

[0043]

[0044] In the formula, Ge represents the water meter accuracy, A represents the displayed flow rate of the water meter, and B represents the nominal flow rate of the water meter.

[0045] Based on the water meter accuracy range specified in the national metrological verification regulation, the cold water meter verification and evaluation module compares the calculated water meter accuracy Ge with it to evaluate whether the current accuracy of the water meter meets the requirements of the national metrological verification regulation. If the regulation stipulates that the allowable error of a certain type of water meter within a certain flow range is ±2%, when the actually calculated water meter error rate is within this range, it is determined that the current accuracy of the water meter meets the requirements; if it exceeds the range, it does not meet the requirements and further analysis of the reasons is needed. According to the evaluation results, the cold water meter remote execution module will put the qualified verification plan into formal use, and the water meter will perform metering and billing according to the verification results. The execution situation feedback and optimization module analyzes the actual operation data of the water meter based on the execution situation, optimizes the verification plan, and ensures that the water meter complies with the metrological standard for a long time.

[0046] The advantages are as follows: By calculating the water meter accuracy Ge, it helps the system quickly evaluate the actual metering accuracy of the current water meter. The formula is directly calculated based on the actual displayed value and the nominal value of the water meter, making the obtained result intuitive and reliable. Based on the water meter accuracy range specified in the national metrological verification regulation, the calculated water meter accuracy Ge is compared with it to evaluate whether the current accuracy of the water meter meets the requirements of the national metrological verification regulation, and it can also ensure the standardization of the water meter accuracy evaluation. Combined with the remote execution module, it can monitor the operation status of the water meter in real time and connect with the execution situation feedback and optimization module, enabling the system to discover problems in a timely manner and solve them.

[0047] The environmental impact analysis unit calculates the user water use environmental impact coefficient Yc according to the environmental data, and its calculation formula is:

[0048]

[0049] In the formula, Yc represents the user water use environmental impact coefficient, which represents the comprehensive impact degree of environmental factors on the user water use flow rate, Δt i and Δp i respectively represent the water temperature deviation and water pressure deviation of the user's water use at the i-th moment under the comprehensive influence of environmental temperature, humidity, and electromagnetic interference intensity. T and P respectively represent the normal water temperature and water pressure of the user's water use, n represents the total number of data acquisition time points, and represents the amount of data collected within a certain time period.

[0050] The cold water meter calibration and evaluation module compares the calculated user water use environment impact coefficient Yc with the pre-set range of user water use environment impact coefficients to evaluate the current environmental impact on the water meter. The user water use environment impact coefficient Yc is obtained by comprehensively calculating the temperature, humidity, and electromagnetic interference intensity data collected by the environmental data acquisition unit. When the calculated user water use environment impact coefficient Yc is within the normal range, it indicates that the environmental impact on the water meter is within an acceptable level; if it exceeds the range, it means that environmental factors may have a greater impact on the accuracy and stability of the water meter, and corresponding measures need to be taken, such as adjusting the installation position or adding protective devices;

[0051] Embodiment 1

[0052] T1. The environmental data acquisition unit substitutes the collected temperature, humidity, and electromagnetic interference intensity data into the calculation formula in the above environmental impact analysis unit to calculate the user water use environment impact coefficient of the current user;

[0053] T2. The cold water meter calibration and evaluation module compares the calculated coefficient with the pre-set range. If the calculation result of the user water use environment impact coefficient Yc is within the normal range, it indicates that the current environmental impact on the water meter is within an acceptable level, and then transmits the command of normal operation to the cold water meter remote execution module, indicating that the current water meter can accurately measure the water consumption and no special measures need to be taken;

[0054] T3. When the calculation result of the user water use environment impact coefficient Yc exceeds the range, it means that the environmental factors at this time have an impact on the accuracy and stability of the water meter, and it is necessary to further analyze what environmental factors cause the impact and take corresponding measures.

[0055] The advantages are as follows: By calculating the user water use environment impact coefficient Yc, the impact of environmental factors on water meter measurement can be quantified. Traditional water meter calibration mainly focuses on the performance of the water meter itself and ignores environmental factors. Now, through the user water use environment impact coefficient Yc, environmental impacts can be incorporated into the evaluation system, which helps to more comprehensively understand the measurement accuracy of the water meter in the actual use environment.

[0056] The transmission efficiency analysis unit calculates the network delay water use fault index Fx based on the user water use environment impact coefficient Yc and the transmission performance data. The calculation formula is:

[0057]

[0058] In the formula, Fx represents the network delay water use fault index, Yc represents the user water use environment impact coefficient, L represents the network bandwidth, H represents the network delay, D represents the packet loss rate, L z represents the nominal network bandwidth, H z represents the nominal network delay, Dz Indicates the nominal packet loss rate.

[0059] The cold water meter calibration and evaluation module evaluates the comprehensive impact of the environment and network latency on the current water meter based on the range of the network latency water use fault index Fx. The network latency water use fault index Fx is calculated by combining the environmental data and the data of the transmission performance data acquisition unit. When the network latency water use fault index Fx is within the normal range, it indicates that the impact of the environment and network latency on the operation and data transmission of the water meter is small; if the value of the network latency water use fault index Fx exceeds the range, it is necessary to analyze whether the environmental factor is dominant or the network latency problem is more prominent, and then solve it targeted, such as improving the network environment or optimizing the data transmission protocol;

[0060] The advantages are as follows: By calculating the network latency water use fault index Fx, it is possible to comprehensively consider the impact of environmental and network latency factors on the operation data transmission of the cold water meter. Different from the traditional single consideration of environmental factors or network factors, this comprehensive evaluation method can accurately reflect the actual operation status of the system, providing a more comprehensive basis for timely discovering and solving problems. When the network latency water use fault index Fx exceeds the range, the system can determine whether the environmental factor or the network latency problem is more prominent through further analysis, which helps to accurately locate the root cause of the problem, thereby avoiding taking blind measures when solving the problem. When the problem mainly lies in the environmental factor, the environment can be improved targeted instead of blindly optimizing the network, thus improving the efficiency and pertinence of problem-solving.

[0061] The cold water meter remote execution module puts the qualified calibration plan into use according to the evaluation results and feeds back to the optimization module according to the execution situation;

[0062] The execution situation feedback and optimization module makes an analysis based on the execution situation and optimizes and adjusts each module of the system. When it is found that the transmission stability in a certain area is poor, the monitoring strategy of the transmission performance data acquisition unit can be optimized targeted, or the calculation parameters of the transmission efficiency analysis unit can be adjusted to improve the overall performance and calibration accuracy of the system.

[0063] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
