[0139] In Figure 1 In step S106 shown, in order to further ensure the rationality of the flow detection correction value, it is necessary to perform a further separate analysis and calculation on the flow detection correction value, specifically through Figure 4 the steps shown for detailed description.

[0148] Among them, the density deviation reference interval refers to the reference deviation interval where the density is allowed to exist, and the density deviation reference interval is obtained through pre-input.

When the density deviation value is not within the preset density deviation reference interval, it indicates that the density deviation affects the flow rate at this time. Therefore, determine the flow density influence value by querying the density deviation value, which is convenient for subsequent use.

[0153] Step S406: Calculate the sum of the flow density influence value, the flow pipeline influence value and the initial flow detection value as the flow comprehensive influence value.

Determining the pipeline material reference time value by querying through the inspection pipeline material information facilitates subsequent use.

[0163] Step S503: Determine whether the detected pipeline usage time value is less than the pipeline material reference time value. If yes, execute Step S504; if not, execute Step S505.

[0164] Among them, by judging whether the detected pipeline usage time value is less than the pipeline material reference time value, it is determined whether the usage time of the detected pipeline has an impact.

[0165] Step S504: Use the pipeline size impact value as the flow pipeline impact value.

[0166] Among them, when the detected pipeline usage time value is less than the pipeline material reference time value, it indicates that the usage time of the detected pipeline has no impact at this time. Therefore, the pipeline size impact value is used as the flow pipeline impact value, thereby improving the accuracy of the obtained flow pipeline impact value.

[0167] Step S505: Calculate the difference between the detected pipeline usage time value and the pipeline material reference time value and use it as the detected pipeline usage time deviation value.

[0168] Among them, the detected pipeline usage time deviation value refers to the deviation value corresponding to the situation where the usage time of the detected pipeline has a deviation. When the detected pipeline usage time value is not less than the pipeline material reference time value, it indicates that the usage time of the detected pipeline has an impact at this time. Therefore, the difference between the detected pipeline usage time value and the pipeline material reference time value is calculated and used as the detected pipeline usage time deviation value for subsequent use.

[0169] Step S506: Determine the pipeline usage time impact value according to the detected pipeline usage time deviation value.

[0170] Among them, the pipeline usage time impact value refers to the impact degree value generated by the deviation of the usage time of the detected pipeline. By analyzing the detected pipeline usage time deviation value, the pipeline usage time impact value is determined for subsequent use. The specific determination steps of the pipeline usage time impact value refer to Step S600 to Step S606.

[0171] Step S507: Calculate the sum value of the pipeline usage time impact value and the pipeline size impact value and use it as the flow pipeline impact value.

[0172] Among them, by calculating the sum value of the pipeline usage time impact value and the pipeline size impact value and using it as the flow pipeline impact value, the accuracy of the obtained flow pipeline impact value is improved.

[0173] In Figure 5 In the shown Step S506, in order to further ensure the rationality of the pipeline usage time impact value, it is necessary to perform further separate analysis and calculation on the pipeline usage time impact value. Specifically, through Figure 6The steps shown are described in detail.

[0174] Refer to Figure 6 , the method for determining the influence value of the pipeline usage time includes the following steps:

[0175] Step S600: According to the corresponding relationship between the detected pipeline usage time deviation value and the preset time deviation influence value, determine the time deviation influence value corresponding to the detected pipeline usage time deviation value.

[0176] Among them, the time deviation influence value refers to the influence degree value generated only when there is a time deviation. Different detected pipeline usage time deviation values correspond to different time deviation influence values. The time deviation influence value is obtained by querying from a database storing different detected pipeline usage time deviation values and the corresponding time deviation influence values, and this database is obtained through pre-input. Determining the time deviation influence value by querying the detected pipeline usage time deviation value is convenient for subsequent use.

[0177] Step S601: Based on the detection location point, retrieve the surrounding construction type information and the surrounding construction time value.

[0178] Among them, the surrounding construction type information refers to the type information corresponding to the construction carried out at the surrounding location of the detection location at the current time, and the surrounding construction time value refers to the time duration value of the construction carried out at the surrounding location of the detection location.

[0179] Step S602: Determine whether the surrounding construction time value is less than the detected pipeline usage time deviation value. If it is, execute Step S603; if not, execute Step S604.

[0180] Among them, by determining whether the surrounding construction time value is less than the detected pipeline usage time deviation value, it is thereby determined whether the construction carried out at the surrounding location of the detection location has an impact.

[0181] Step S603: Take the time deviation influence value as the pipeline usage time influence value.

[0182] Among them, when the surrounding construction time value is less than the detected pipeline usage time deviation value, it indicates that the construction carried out at the surrounding location of the detection location has no impact at this time. Therefore, the time deviation influence value is taken as the pipeline usage time influence value, thereby improving the accuracy of the obtained pipeline usage time influence value.

[0183] Step S604: Determine the construction type unit influence value according to the surrounding construction type information.

[0184] Among them, the influence value per unit of construction type refers to the influence degree value generated by the type of surrounding construction per unit time. When the surrounding construction time value is not less than the deviation value of the detection pipeline usage time, it indicates that construction is taking place at the surrounding location of the detection position at this time, thus affecting the detection. Therefore, by analyzing the surrounding construction type information, the influence value per unit of construction type is determined to facilitate subsequent use. The specific determination steps of the influence value per unit of construction type refer to Step S700 to Step S707.

[0185] Step S605: Calculate the product value between the influence value per unit of construction type and the surrounding construction time value and use it as the influence value of construction water usage.

[0186] Among them, the influence value of construction water usage refers to the influence degree value generated by the surrounding construction. By calculating the product value between the influence value per unit of construction type and the surrounding construction time value and using it as the influence value of construction water usage, it facilitates subsequent use.

[0187] Step S606: Calculate the sum value between the influence value of construction water usage and the influence value of time deviation and use it as the influence value of pipeline usage time.

[0188] Among them, by calculating the sum value between the influence value of construction water usage and the influence value of time deviation and using it as the influence value of pipeline usage time, the accuracy of the obtained influence value of pipeline usage time is improved.

[0189] In Figure 6 In the shown Step S604, in order to further ensure the rationality of the influence value per unit of construction type, it is necessary to conduct a further separate analysis and calculation of the influence value per unit of construction type. Specifically, it is described in detail through the Figure 7 shown steps.

[0190] Refer to Figure 7 , the determination method of the influence value per unit of construction type includes the following steps:

[0191] Step S700: According to the correspondence between the surrounding construction type information and the preset water usage value per unit of type, determine the water usage value per unit of type corresponding to the surrounding construction type information.

[0192] Among them, the water usage value per unit of type refers to the influence degree value generated per unit time when the type of surrounding construction uses water. Different surrounding construction type information corresponds to different water usage values per unit of type. The water usage value per unit of type is obtained by querying from a database that stores different surrounding construction type information and the corresponding water usage values per unit of type. This database is obtained through pre-input. Determining the water usage value per unit of type by querying the surrounding construction type information facilitates subsequent use.

[0193] Step S701: Based on the surrounding construction type information, retrieve the type construction time period.

[0194] Among them, the type construction time period refers to the time period during which the construction of the surrounding construction of the corresponding type is carried out. The construction time period corresponding to the type is queried through the surrounding construction type information and used as the type construction time period for subsequent use.

[0195] Step S702: Determine whether there is an overlapping situation between the type construction time period and the preset daily water use time period. If yes, execute Step S703; if no, execute Step S706.

[0196] Among them, the daily water use time period refers to the time period during which daily water use occurs, and the daily water use time period is obtained through pre-input. By judging whether there is an overlapping situation between the type construction time period and the preset daily water use time period, it is thus judged whether the water use for the construction of the surrounding construction of the corresponding type has a separate impact.

[0197] Step S703: Determine the water use overlapping time period based on the type construction time period and the preset daily water use time period.

[0198] Among them, the water use overlapping time period refers to the time period corresponding to the overlapping time of the water use for the construction of the surrounding construction of the corresponding type and the daily water use. When there is an overlapping situation between the type construction time period and the preset daily water use time period, it indicates that the water use for the construction of the surrounding construction of the corresponding type does not have a separate impact at this time. Therefore, by analyzing the type construction time period and the preset daily water use time period, and taking the overlapping time period as the water use overlapping time period for subsequent use.

[0199] Step S704: Determine the water use overlapping time impact value corresponding to the water use overlapping time period according to the corresponding relationship between the water use overlapping time period and the preset water use overlapping time impact value.

[0200] Among them, the water use overlapping time impact value refers to the impact degree value generated when there is water use overlap. Different water use overlapping time periods correspond to different water use overlapping time impact values. The water use overlapping time impact value is obtained by querying from a database storing different water use overlapping time periods and the corresponding water use overlapping time impact values, and this database is obtained through pre-input. By querying through the water use overlapping time period to determine the water use overlapping time impact value, it is thus convenient for subsequent use.

[0201] Step S705: Calculate the product value of the water use overlapping time impact value and the type water use unit value and use it as the construction type unit impact value.

[0202] Among them, by calculating the product value of the water use overlapping time impact value and the type water use unit value and using it as the construction type unit impact value, the accuracy of the obtained construction type unit impact value is improved.

[0203] Step S706: Determine the construction time impact value corresponding to the type construction time period according to the correspondence between the type construction time period and the preset construction time impact value.

[0204] Among them, the construction time impact value refers to the impact degree value generated by the construction time. Different type construction time periods correspond to different construction time impact values. The construction time impact value is obtained by querying from a database that stores different type construction time periods and the corresponding construction time impact values. This database is obtained through pre-input. When there is no overlap between the type construction time period and the preset daily water use time period, it means that the water use during the construction of the surrounding construction of this type has a separate impact. Therefore, the construction time impact value is determined by querying through the type construction time period, which is convenient for subsequent use.

[0205] Step S707: Calculate the product value of the construction time impact value and the type water use unit value and use it as the construction type unit impact value.

[0206] Among them, by calculating the product value of the construction time impact value and the type water use unit value and using it as the construction type unit impact value, it is convenient for subsequent use.

[0207] After Figure 4 the step S401 shown, in order to further ensure the rationality of the flow pipeline impact value, it is necessary to conduct a further separate analysis and calculation of the flow pipeline impact value, which is specifically described in detail through the following steps.

[0208] The steps after determining the flow pipeline impact value according to the detected pipeline specification information include the following steps:

[0209] Step S800: Retrieve the surrounding environmental noise value based on the detection location point.

[0210] Among them, the surrounding environmental noise value refers to the noise value generated by the surrounding environment of the detection location. By retrieving the type information of the surrounding environment through the detection location point and querying the preset environmental noise database according to the type of the surrounding environment, the surrounding environmental noise value can be obtained, which is convenient for subsequent use. The environmental noise database pre-stores different types of surrounding environments and the corresponding surrounding environmental noise values.

[0211] Step S801: Determine the material noise isolation value corresponding to the detected pipeline material information according to the correspondence between the detected pipeline material information and the preset material noise isolation value.

[0212] Among them, the material noise isolation value refers to the noise value that the material of the detection pipeline can isolate. Different detection pipeline material information corresponds to different material noise isolation values. The material noise isolation value is obtained by querying from a database that stores different detection pipeline material information and the corresponding material noise isolation values. This database is obtained through pre-input. Querying and determining the material noise isolation value through the detection pipeline material information facilitates subsequent use.

[0213] Step S802: Determine whether the ambient environment noise value is less than the material noise isolation value. If yes, execute step S803; if no, execute step S804.

[0214] Among them, by determining whether the ambient environment noise value is less than the material noise isolation value, it is thus determined whether the noise in the ambient environment will have an impact.

[0215] Step S803: Continue to output the flow pipeline impact value.

[0216] Among them, when the ambient environment noise value is less than the material noise isolation value, it indicates that the noise in the ambient environment will not have an impact at this time. Therefore, continue to output the flow pipeline impact value, thereby improving the accuracy of the obtained flow pipeline impact value.

[0217] Step S804: Calculate the difference between the ambient environment noise value and the material noise isolation value and use it as the penetration noise value.

[0218] Among them, the penetration noise value refers to the noise value that affects the ultrasonic wave by penetrating the pipeline. When the ambient environment noise value is not less than the material noise isolation value, it indicates that the noise in the ambient environment will have an impact at this time. Therefore, calculate the difference between the ambient environment noise value and the material noise isolation value and use it as the penetration noise value to facilitate subsequent use.

[0219] Step S805: According to the corresponding relationship between the penetration noise value and the preset environmental noise impact value, determine the environmental noise impact value corresponding to the penetration noise value, and use the environmental noise impact value to adjust the flow pipeline impact value to form a new flow pipeline impact value and replace it.

[0220] Among them, the environmental noise impact value refers to the impact degree value generated by the noise in the ambient environment. Different penetration noise values correspond to different environmental noise impact values. The environmental noise impact value is obtained by querying from a database that stores different penetration noise values and the corresponding environmental noise impact values. This database is obtained through pre-input. Querying and determining the environmental noise impact value through the penetration noise value, and using the environmental noise impact value to adjust the flow pipeline impact value to form a new flow pipeline impact value and replace it, thereby improving the accuracy of the obtained flow pipeline impact value.
