[0081] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0082] A smart water meter warning method obtains real-time water volume detection values, water pressure detection values, current time point and current position point, thereby performing water leakage warning analysis based on the water volume and water pressure at the current time point and issuing a warning when a water leakage occurs, thereby facilitating timely warning of water leakage, and when there is a spare pipeline at the current position point, the spare pipeline can be controlled to handle the leakage, thereby reducing the waste of water resources.

[0083] The embodiment of the present invention discloses a smart water meter warning method. Figure 1 , a smart water meter warning method includes:

[0084] Step S100: obtaining a real-time water volume detection value on a water meter and a water pressure detection value collected by a water pressure detection device preset on the water meter.

[0085] Among them, the real-time water volume detection value refers to the detection value of the water volume at the current time, and the real-time water volume detection value is obtained by detection through the water meter. The water pressure detection value refers to the detection value of the water pressure at the current time, and the water pressure detection value is collected and obtained by a water pressure detection device preset on the water meter. The water pressure detection device refers to a device for detecting the water pressure flowing through the water meter.

[0086] Step S200: Calculate the difference between the water pressure detection value and the preset water pressure reference value and use it as the water pressure deviation value.

[0087] The water pressure reference value refers to the reference value of the water pressure at the water meter under normal conditions, and the water pressure reference value is obtained after pre-input by the operator. The water pressure deviation value refers to the deviation value when the water pressure at the water meter deviates. The difference between the water pressure detection value and the preset water pressure reference value is calculated and used as the water pressure deviation value for subsequent use.

[0088] Step S300: Analyze and determine the water pressure reference deviation interval based on the real-time water volume detection value.

[0089] Among them, the water pressure reference deviation range refers to the allowable deviation range of water pressure deviation without water leakage. By analyzing the real-time water volume detection value, the water pressure reference deviation range is determined to facilitate subsequent use.

[0090] Step S400: Determine whether the water pressure deviation value falls within the water pressure reference deviation range. If yes, execute step S500; if no, execute step S600.

[0091] The presence of a water leak is determined by determining whether the water pressure deviation value falls within the water pressure reference deviation interval.

[0092] Step S500: Continue to obtain the real-time water volume detection value and water pressure detection value.

[0093] Among them, when the water pressure deviation value falls within the water pressure reference deviation range, it means that there is no water leakage at this time, so the real-time water volume detection value and water pressure detection value continue to be obtained.

[0094] Step S600: determining water leakage warning information according to the water pressure deviation value and the water pressure reference deviation interval analysis, and outputting the water leakage warning information to the terminal held by the manager.

[0095] Among them, the water leakage warning information refers to the warning information for warning of water leakage, and the terminal held by the administrator refers to the terminal that can receive information, and the terminal held by the administrator can be a mobile phone or a computer. When the water pressure deviation value does not fall within the water pressure reference deviation interval, it means that there is a water leakage at this time. Therefore, by analyzing the water pressure deviation value and the water pressure reference deviation interval, the water leakage warning information is determined and output to the terminal held by the administrator. By detecting the real-time water volume and water pressure and analyzing the water leakage situation, the water leakage warning information is sent when a water leakage occurs, which is convenient for timely warning of the water leakage situation.

[0096] exist Figure 1In step S300, in order to further ensure the rationality of the water pressure reference deviation interval, it is necessary to further analyze and calculate the water pressure reference deviation interval separately, specifically by Figure 2 The steps shown are explained in detail.

[0097] Reference Figure 2 , the method for determining the water pressure reference deviation interval includes the following steps:

[0098] Step S310: Calculate the difference between two real-time water volume detection values ​​separated by adjacent unit time periods and use it as the water volume unit time change value.

[0099] The water volume change value per unit time refers to the change value corresponding to the change in water volume in unit time. The unit time is preset by the operator and can be 1 second. The difference between two real-time water volume detection values ​​separated by adjacent unit time is calculated and used as the water volume change value per unit time, which is convenient for subsequent use.

The water volume change value during the same period is stored through the real-time water volume detection value and then retrieved by querying the corresponding historical time point through the current time point.

[0106] Step S350: Retrieve the change duration value based on the water volume change value per unit time.

[0107] The change duration value refers to the duration value corresponding to the change in water volume. By counting the unit time change value of water volume and using the formed time value as the unit time change value of water volume, subsequent use is facilitated.

[0108] Step S360: Determine the comprehensive impact value of the change based on the water volume change value and the change duration value during the same period.

[0109] Among them, the comprehensive impact value of changes refers to the degree of influence of changes in water volume on the deviation range of water pressure. By analyzing the water volume change value and the change duration value in the same period, the comprehensive impact value of changes can be determined to facilitate subsequent use.

[0110] Step S370: adjusting the unit time initial interval based on the comprehensive impact value of the change to form a unit time adjustment interval, and using the unit time adjustment interval as the water pressure reference deviation interval.

[0111] Among them, the unit time adjustment interval refers to the interval after the deviation interval of the water pressure is adjusted according to the unit time. The unit time adjustment interval is formed by adjusting the initial unit time interval according to the comprehensive impact value of the change and serving as the water pressure benchmark deviation interval. The obtained water pressure benchmark deviation interval is affected by the unit time change value of the water volume and the current time point, thereby improving the accuracy of the obtained water pressure benchmark deviation interval.

The difference between the water volume change value per unit time and the water volume change value in the same period is calculated and used as the deviation value of the change in the same period, which is convenient for subsequent use.

[0116] Step S362: According to the correspondence between the contemporaneous change deviation value and the preset contemporaneous change deviation impact value, the contemporaneous change deviation impact value corresponding to the contemporaneous change deviation value is determined.

[0117] The impact value of the deviation of the change in the same period refers to the impact value caused by the deviation of the change in water volume between the current time and the same period. The impact value of the deviation of the change in the same period is obtained by querying from a database storing the deviation value of the change in the same period and the impact value of the deviation of the change in the same period. The database is obtained and stored through experiments. The impact value of the deviation of the change in the same period is determined by querying the deviation value of the change in the same period, which is convenient for subsequent use.

[0118] Step S363: Calculate the difference between the change duration value and the preset duration reference value and use it as the duration deviation value.

[0119] The duration reference value refers to the longest duration of the water volume change during normal use, and the duration reference value is obtained after being pre-entered by the operator. The duration deviation value refers to the deviation value when there is a deviation in the duration of the water volume change. The difference between the duration value of the change and the preset duration reference value is calculated and used as the duration deviation value for subsequent use.

[0120] Step S364: Determine the duration deviation impact value corresponding to the duration deviation value according to the corresponding relationship between the duration deviation value and the preset duration deviation impact value.

[0121] Among them, the duration deviation impact value refers to the impact degree value caused by the deviation of the duration of water volume change. The duration deviation impact value is obtained by querying from a database storing duration deviation values ​​and duration deviation impact values. The database is obtained and stored through experiments. The duration deviation impact value is determined by querying the duration deviation value, which is convenient for subsequent use.

[0122] Step S365: Calculate the sum of the impact value of the concurrent change deviation and the impact value of the duration deviation and use it as the comprehensive impact value of the change.

[0123] Among them, by calculating the sum of the impact value of the concurrent change deviation and the impact value of the duration deviation and using it as the comprehensive impact value of the change, the comprehensive impact value of the change is affected by both the concurrent change deviation and the duration deviation, thereby improving the accuracy of the obtained comprehensive impact value of the change.

[0126] Step S610: Calculate the difference between the water pressure deviation value and the water pressure reference deviation interval and use it as the water pressure abnormal value.

[0127] Among them, the water pressure abnormal value refers to the abnormal value when the water pressure is abnormal. The difference between the water pressure deviation value and the water pressure reference deviation interval is calculated and used as the water pressure abnormal value to facilitate subsequent use.

[0128] Step S620: query and match the initial estimated cause information of the water pressure anomaly based on the water pressure anomaly value.

[0129] Among them, the initial estimated cause information of water pressure anomaly refers to the initial cause information estimated when the water pressure is abnormal. The water pressure anomaly value is queried and matched with the preset estimated cause database, and the estimated cause of the water pressure anomaly value falling into the corresponding interval in the estimated cause database is used as the initial estimated cause information of water pressure anomaly, which is convenient for subsequent use. The estimated cause database can be obtained by querying the website related to water pressure anomaly, and the estimated cause database can also be obtained and stored through experiments.

[0130] Step S630: Retrieve the estimated cause time value and the estimated cause reference abnormal interval based on the initial estimated cause information of the water pressure abnormality.

[0131] Among them, the estimated cause time value refers to the minimum duration value required for the estimated initial cause to cause the water pressure abnormality, and the estimated cause benchmark abnormality interval refers to the benchmark interval for the estimated initial cause to cause the water pressure abnormality. The estimated cause time value and the estimated cause benchmark abnormality interval are retrieved through the initial estimated cause information of the water pressure abnormality to facilitate subsequent use.

[0137] Among them, the abnormal time deviation value refers to the deviation value when the duration of the water pressure abnormality deviates from the benchmark duration corresponding to the estimated cause. The difference between the abnormal time value and the estimated cause time value is calculated and used as the abnormal time deviation value, which is convenient for subsequent use.

[0138] Step S670: selecting and analyzing the initial estimated cause information of the water pressure anomaly according to the abnormal deviation information and the abnormal time deviation value to form the selected cause information of the water pressure anomaly.

[0140] Step S680: Combine the water pressure abnormality selection cause information, the water pressure abnormality value and the abnormal time value to form the selection cause warning information, and use the selection cause warning information as the water leakage warning information.

[0141] Among them, the selected cause warning information refers to the warning information for warning of the selected cause. By combining the selected cause information of water pressure abnormality, the water pressure abnormality value and the abnormal time value, the selected cause warning information is formed and used as water leakage warning information, thereby improving the accuracy of the obtained water leakage warning information.

Figure 5 The steps shown are explained in detail.

[0143] Reference Figure 5 The method for selecting the cause information of water pressure anomaly includes the following steps:

[0144] Step S671: retrieve the abnormal intermediate deviation value and the abnormal maximum deviation value based on the abnormal deviation information.

[0145] Among them, the abnormal middle deviation value refers to the deviation value when there is a deviation from the middle value of the interval, and the abnormal maximum deviation value refers to the deviation value when there is a deviation from the maximum value of the interval.

When the selected cause type information belongs to the preset pipeline cause type information, it means that a spare pipeline can be used to pre-process the water leakage at this time, so the current location point is obtained for subsequent use.

[0162] Step S684: Retrieve backup pipeline information based on the current location point.

[0163] Among them, the backup pipeline information refers to the relevant parameter information of the backup pipeline located at the current position. The backup pipeline information is retrieved through the current position point to facilitate subsequent use.

[0164] Step S685: Analyze and select pipeline specification information based on the backup pipeline information.

[0165] The selected pipeline specification information refers to the pipeline specification information corresponding to the backup pipeline after selection. The selected pipeline specification information is determined by analyzing the backup pipeline information to facilitate subsequent use.

[0166] Step S686: Determine the selection specification reference value corresponding to the selected pipeline specification information according to the correspondence between the selected pipeline specification information and the preset selection specification reference value.

[0167] Among them, the selected specification reference value refers to the reference control value corresponding to the abnormal water pressure unit when the selected spare pipeline is used. The selected specification reference value is obtained by querying from a database storing the selected pipeline specification information and the selected specification reference value, which is obtained and stored through experiments. The selected specification reference value is determined by querying the selected pipeline specification information to facilitate subsequent use.

[0168] Step S687: Calculate the product value between the abnormal water pressure value and the selected specification reference value and use it as the specification adjustment control value.

[0169] Among them, the specification adjustment control value refers to the control value for opening the standby pipeline based on the abnormal water pressure value. The product value between the abnormal water pressure value and the selected specification reference value is calculated and used as the specification adjustment control value for subsequent use.

[0170] Step S688: Combine the specification adjustment control value with the selected pipeline specification information to form backup pipeline warning information, add the backup pipeline warning information to the water leakage warning information to form new water leakage warning information, and output the backup pipeline warning information to the backup pipeline control device preset on the water meter.

[0171] Among them, the backup pipeline warning information refers to the warning information for using the backup pipeline in case of water leakage, and the backup pipeline control device refers to the device used to control the opening of the backup pipeline at the location of the water meter. There are multiple backup pipelines connected to the water meter, and the backup pipeline control device is preset on the water meter and used to control the opening of the connected backup pipeline. The backup pipeline warning information is formed by combining the specification adjustment control value with the selected pipeline specification information, and the backup pipeline warning information is added to the water leakage warning information to form a new water leakage warning information, and the backup pipeline warning information is output to the backup pipeline control device preset on the water meter, so as to control the opening of the backup pipeline and issue a warning at the same time, so as to facilitate timely warning of water leakage and reduce the waste of water resources.

[0172] Step S689: Continue to output water leakage warning information.

[0173] When the selected cause type information does not belong to the preset pipeline cause type information, it means that the backup pipeline cannot be used to pre-process the water leakage at this time, so the water leakage warning information continues to be output.

[0174] exist Figure 6 In step S685, in order to further ensure the rationality of the selected pipeline specification information, it is necessary to further analyze and calculate the selected pipeline specification information. Figure 7 The steps shown are explained in detail.

[0175] Reference Figure 7 , the method for determining the pipeline specification information includes the following steps:

[0176] Step S6851: Retrieve the number of backup pipes and backup pipe specification information based on the backup pipe information.

[0177] The standby pipeline information includes the standby pipeline number value and the standby pipeline specification information. The standby pipeline number value refers to the number value corresponding to the standby pipeline connected at the water meter, and the standby pipeline specification information refers to the specification information corresponding to the standby pipeline connected at the water meter. The standby pipeline number value and the standby pipeline specification information are retrieved through the standby pipeline information to facilitate subsequent use.

[0178] Step S6852: Determine whether the number of standby pipelines is only one. If yes, execute step S6853; if no, execute step S6854.

[0179] Here, it is determined whether the spare pipeline is directly used by judging whether the value of the spare pipeline is only one.

[0180] Step S6853: directly use the spare pipeline specification information as the selected pipeline specification information.

[0181] Among them, when the value of the number of spare pipelines is only one, it means that the spare pipeline is directly used at this time, so the spare pipeline specification information is directly used as the selected pipeline specification information.

[0182] Step S6854: Retrieve the backup pipe diameter value based on the backup pipe specification information.

[0183] The spare pipe specification information includes the spare pipe diameter value, which refers to the diameter value corresponding to the spare pipe connected to the water meter. When the spare pipe value is more than one, it means that a spare pipe needs to be selected for use. Therefore, the spare pipe diameter value is retrieved through the spare pipe specification information for subsequent use.

[0184] Step S6855: Determine the allowable water volume value corresponding to the backup pipe diameter value according to the correspondence between the backup pipe diameter value and the preset allowable water volume value.

[0185] The water volume allowable value refers to the water volume value allowed to pass through the backup pipeline. The water volume allowable value is obtained by querying from a database storing backup pipeline diameter values ​​and water volume allowable values. The database is obtained by querying from pipeline-related websites. The water volume allowable value is determined by querying the backup pipeline diameter value to facilitate subsequent use.

[0186] Step S6856: Calculate the difference between the allowable water volume value and the real-time water volume detection value and use it as the allowable water volume deviation value.

[0187] Among them, the allowable deviation value of water volume refers to the deviation value when there is a deviation in the amount of water allowed to pass through the backup pipeline. The difference between the allowable water volume value and the real-time water volume detection value is calculated and used as the allowable deviation value of water volume, which is convenient for subsequent use.

[0188] Step S6857: Sort the water volume allowable deviation values ​​from small to large, and use the spare pipeline specification information corresponding to the first positive water volume allowable deviation value as the selected pipeline specification information.

[0189] The accuracy of the selected pipeline specification information is improved by sorting the water volume allowable deviation values ​​from small to large and using the spare pipeline specification information corresponding to the first positive water volume allowable deviation value as the selected pipeline specification information.
