Description of the embodiments
The embodiment of the application provides a data processing method, a related device, equipment and a storage medium, which can deduce unknown target parameters according to constant constants and parameters measured at measuring point positions. Therefore, there is no need to deploy a sensor for measuring the target parameter, thereby reducing deployment costs.

It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the application described herein may be implemented, for example, in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "includes" and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus.
Digital twinning is a virtualization technique that digitizes physical objects and builds a model to facilitate analysis and optimization thereof. In the industry, digital twinning can effectively reduce time, cost and safety risks in the production process. Digital twinning plays a significant role in the field of urban infrastructure, especially in the field of pipelines.
In constructing a digital twin model of a pipeline type, it is often necessary to acquire different types of parameters. In the process of delivering the fluid to the target position, as the fluid may be transported over a long distance, information parameters such as the speed, flow rate, pressure and the like of the fluid operation are difficult to obtain in the process of delivering. If various sensors are installed at each important node of the pipeline to collect data for analysis, the analysis is time-consuming and labor-consuming, and a great deal of capital cost is required to be invested.
Based on the above, in the embodiment of the application, a data processing method is provided. In one aspect, unknown target parameters are derived from parameters measured at the measurement point locations based on Bernoulli's theorem, thereby reducing sensor deployment. On the other hand, the real-time monitoring of the fluid operation in the pipeline is realized by means of the digital twin technology and the cloud primary technology, and a reference is provided for analyzing the fluid operation condition. Therefore, the method is not only convenient for staff to know what problems are encountered in the conveying process in time and pre-judge the risks in advance, but also is beneficial for scientific researchers to study the fluid states of different positions. The data processing method provided by the application comprises at least one of the following scenes when applied.
1. Risk analysis and early warning;
based on technologies such as digital twinning, artificial intelligence, big data analysis and the like, the active early warning, pre-diagnosis and in-event warning functions of the abnormal event are realized, and the occurrence of the unexpected event is effectively avoided.
Taking an underground water delivery scene as an example, based on the scheme provided by the application, firstly, an initial point position (for example, the water inlet position of a certain section of pipeline) and at least one measuring point position are determined from a water delivery pipeline. Then, an initial point height, an initial point flow rate, and an initial point static pressure of the initial point position are collected, and a corresponding fluid density is inquired according to a target fluid (e.g., tap water) flowing in the water pipe. Next, the computer device calculates a constant based on the initial point height, the initial point flow rate, the initial point static pressure, and the fluid density.
Based on this, taking a certain measuring point position as an example, the relevant parameters of the measuring point position, such as the measuring point height difference and the measuring point static pressure, are collected. The flow rate at the location of the measurement point can then be deduced using a constant. When the flow rate is detected to be too high or too low, early warning information can be pushed to staff in real time, so that on-site maintenance work can be carried out in time.
2. Constructing a pipeline;
the pipeline layout planning can utilize a digital twin technology and combine data such as urban geographic information systems, population distribution, rainfall conditions and the like to analyze and simulate, so that an optimal pipeline layout scheme is obtained. Meanwhile, the capacity and the bearing capacity of the pipe network are considered, so that the high-efficiency operation of the drainage system is ensured.
Taking the arrangement of the drain pipe as an example, based on the scheme provided by the application, firstly, an initial point position and at least one measuring point position are determined from the water pipe. Then, an initial parameter set (e.g., an initial point height, an initial point flow rate, and an initial point static pressure) of the initial point position is acquired, and a corresponding fluid density is queried according to a target fluid flowing in the water pipe. Next, the computer device calculates a constant based on the initial set of parameters and the fluid density.
Based on this, taking a certain measurement point position as an example, the relevant parameters of the measurement point position, such as the measurement point flow velocity and the measurement point static pressure, are collected. The static pressure at the location of the measurement point can then be deduced using a constant. Various devices, such as a pump station, a valve, a detection instrument and the like, can be reasonably configured and installed according to the static pressure of the position of the measuring point.
3. Training and experiment;
the maintenance work of pipelines for transporting corrosive liquids is an extremely safe operation, and is an important link for production operation for the training work of staff. The entity model used in the practice course often has a larger gap with the real pipe network system, so that a more real learning environment can be provided for training staff through the digital twin pipe network system platform.
The operation of the digital twin pipe network system platform depends on the collection and use of a large amount of data. Based on the solution provided by the application, first, an initial point position and at least one measuring point position are determined from the pipeline. Then, an initial parameter set of the initial point position is acquired, and the corresponding fluid density is inquired according to the target fluid flowing in the water conveying pipeline. Next, the computer device calculates a constant based on the initial set of parameters and the fluid density.
Based on this, taking a certain measuring point position as an example, the relevant parameters of the measuring point position are collected. Thus, the relevant parameters of the measurement point position can be deduced using the constant constants to deduce other target parameters of the measurement point position. And constructing a virtual pipe network by using the parameters.

if the measurement parameter set comprises the measurement point static pressure, determining that the initial point static pressure is unchanged from the measurement point static pressure under the condition that the measurement point static pressure is consistent with the initial point static pressure;
if the measurement parameter set comprises the measurement point static pressure, determining that the measurement point static pressure is changed compared with the initial point static pressure under the condition that the measurement point static pressure is inconsistent with the initial point static pressure;
or alternatively, the first and second heat exchangers may be,
before determining the target parameter of the measuring point position according to the measuring parameter set and the constant corresponding to the target pipeline, the method may further include:
acquiring an initial radius of a target pipeline at an initial point position and a measurement radius at a measurement point position;
under the condition that the initial radius is consistent with the measurement radius, determining that the static pressure of the measurement point is unchanged from the static pressure of the initial point;
in the case where the initial radius does not coincide with the measured radius, it is determined that the initial point static pressure changes from the measured point static pressure.
In one or more embodiments, three ways of measuring the static pressure at the point and the change in the static pressure at the initial point are described. As can be seen from the foregoing embodiments, before determining the target parameter of the measurement point position, it is also necessary to determine whether the measurement point static pressure changes from the initial point static pressure, so as to perform subsequent calculation according to the change situation. These three modes will be described separately below.
A first mode, a control variable method;
specifically, the sum of static pressure, dynamic pressure and gravity of the target pipeline at different position points meets the energy conservation relation. Wherein dynamic pressure is related to flow rate and fluid density, while the fluid density of the target fluid remains unchanged. Based on this, if the measurement point gravity coincides with the initial point gravity and the measurement point flow rate coincides with the initial point flow rate, it means that the initial point static pressure does not change from the measurement point static pressure. If the measurement point gravity is consistent with the initial point gravity, but the measurement point flow rate is inconsistent with the initial point flow rate, it indicates that the initial point static pressure has changed from the measurement point static pressure.
A second mode, a measurement method;
specifically, a pressure sensor is directly deployed at the measurement point location, through which the measurement point static pressure is directly measured. Based on this, if the measured measurement point static pressure coincides with the initial point static pressure, it means that the measurement point static pressure does not change from the initial point static pressure. If the measured static pressure at the measuring point is not consistent with the static pressure at the initial point, the static pressure at the measuring point is changed from the static pressure at the initial point.
A third mode, an empirical method;
specifically, pipe lay data of a target pipe is acquired, wherein the pipe lay data may be represented in a pictorial form. Thus, the radius of the target pipeline at different locations can be obtained from the pipelining data. Namely, the initial radius of the initial point position and the measurement radius at the measurement point position are obtained. It is empirically known that when the radius of the pipe changes, the flow rate and, therefore, the static pressure changes accordingly. Based on this, if the initial radius coincides with the measured radius, it means that the initial point static pressure does not change from the measured point static pressure. If the initial radius does not coincide with the measured radius, it means that the initial point static pressure has changed from the measured point static pressure.
In the embodiment of the application, three ways of measuring the static pressure of the point and the change condition of the static pressure of the initial point are provided. By the mode, in practical application, the static pressure of the measuring point and the change condition of the static pressure of the initial point can be judged according to the parameter acquisition condition, so that the flexibility and operability of the scheme are improved.
Optionally, on the basis of one or more embodiments corresponding to fig. 3, in another optional embodiment provided by the embodiment of the present application, the target parameter is a flow rate parameter;
Based on the change condition of the static pressure of the measuring point compared with the static pressure of the initial point, determining the target parameter of the measuring point position according to the measuring parameter set and the constant corresponding to the target pipeline specifically can comprise:
based on the change condition of the static pressure of the measuring point compared with the static pressure of the initial point, the flow rate parameter of the measuring point position is calculated according to the initial point height, the measuring point height, the initial point flow rate, the static pressure of the initial point, the fluid density corresponding to the target fluid, the gravity acceleration and the constant corresponding to the target pipeline.
In one or more embodiments, a manner of calculating a flow rate parameter corresponding to a measurement point location is described. As can be seen from the foregoing embodiments, the target parameter is a flow rate parameter, that is, the unknown parameter to be solved is a measurement point flow rate of the measurement point position. Under the condition that the initial point height, the measurement point height, the initial point flow velocity, the initial point static pressure, the fluid density corresponding to the target fluid, the gravity acceleration and the constant are known, the flow velocity parameter of the measurement point position can be deduced based on the change condition of the measurement point static pressure compared with the initial point static pressure.

In step E2, the server introduces the bernoulli equation for calculation. The bernoulli equation may refer to the foregoing formula (1), and will not be described herein.
In step E3, a constant is calculated based on the bernoulli equation.
In step E4, the height of each node position in the target pipeline is input, so that the measurement point height corresponding to the measurement point position can be obtained.
In step E5, a flow rate parameter for the position of the measurement point is calculated based on the constant and the measurement point height.
In step E6, according to the flow rate parameters of each measuring point position and the pipeline laying data of the target pipeline, determining the flow rate parameters corresponding to the different interval sections of the target pipeline, and then fusing the flow rate parameters corresponding to the different interval sections with the BIM of the target pipeline.
In step E7, a flow rate analysis is performed based on the flow rate parameter at the measurement point position.
In step E8, it is determined whether the flow rate parameter at the measurement point is too fast or too slow, and if so, step E9 is performed.
In step E9, a warning is pushed if the flow rate parameter is too fast or too slow.
In step E10, pipe laying data of the target pipe, for example, pipe radius, pipe length, and the like are read.
In step E11, matrix transformation is performed on the fused data, and the data of the target pipeline is converted into a three-dimensional coordinate system, so as to obtain three-dimensional model data of the target pipeline.
In step E12, the three-dimensional model data is pushed to the terminal.
In step E13, the terminal performs three-dimensional rendering based on the three-dimensional model data, so that the flow direction, the shape, and the like of the fluid can be displayed, so that the system captures the running state of the fluid in real time and displays the state.
In the embodiment of the application, a mode for calculating the flow velocity parameter corresponding to the position of the measuring point is provided. In this manner, the target parameter (e.g., flow rate parameter) is calculated from different dimensions during fluid flow using the Bernoulli equation. Therefore, the loss of the sensor is reduced, and the real-time observation and analysis of the fluid operation are realized, so that the aims of reducing the cost and enhancing the efficiency are fulfilled.

and solving the dynamic pressure of the measuring point based on the first identity to obtain the flow velocity parameter of the position of the measuring point.
In one or more embodiments, a manner of calculating a flow rate parameter when static pressure is unchanged is presented. From the foregoing embodiments, the initial point flow rate may be collected at the fluid input port of the target conduit, and the flow rate parameter at the location of the measurement point may be derived by combining the initial point height, the measurement point height, the initial point static pressure (i.e., typically the local atmospheric pressure), the fluid density of the target fluid, and the gravitational acceleration.
Specifically, the initial point dynamic pressure can be calculated from the initial point flow rate and the fluid density corresponding to the target fluid as follows:

H 0 Representing the initial point height, +.>Representing the difference in height of the measurement point.
Due to the flow rate parameter at the location of the measurement point (i.e., v i ) Is unknown, and therefore, the measured point dynamic pressure belongs to an unknown term. In the case where the measurement point static pressure does not change from the initial point static pressure, that is, the measurement point static pressure is equal to the initial point static pressure, it is not necessary to consider the influence of the static pressure change when solving the flow rate parameter at the measurement point position.
Two implementations of deriving flow rate parameters for the location of the measurement point while the static pressure remains the same will be described below.

According to the embodiment, after the static pressure parameters of different measuring point positions are calculated, the static pressure parameters can be fused with the BIM of the target pipeline, so that the static pressure is dynamically displayed to the corresponding position of the target pipeline in real time, and the purpose of monitoring the hydrostatic pressure in real time is achieved.
Specifically, after the static pressure parameter of a certain measuring point position is calculated, the corresponding static pressure parameter can be mapped to the section pipeline corresponding to the target pipeline according to the position of the measuring point position in the target pipeline, so that the static pressure parameter of the section pipeline is obtained. And by analogy, the static pressure parameter of each interval pipeline in the target pipeline can be obtained. Further, the static pressure parameters of the interval pipelines are fused with the laying radius of the corresponding interval pipeline and the laying length of the interval pipeline, and then the target pipeline is converted into a three-dimensional coordinate system in a homogeneous coordinate transformation mode, so that corresponding three-dimensional model data are obtained.

under the condition that the static pressure of the measuring point is changed from the initial point static pressure, calculating to obtain the total pressure parameter of the position of the measuring point according to the dynamic pressure of the measuring point and the static pressure of the measuring point.
In one or more embodiments, a manner of calculating a total pressure parameter is presented. As can be seen from the foregoing embodiments, the target parameter is a total pressure parameter, that is, the unknown parameter to be solved is a measurement point total pressure of the measurement point position.

Specifically, for ease of understanding, referring to fig. 20, fig. 20 is a schematic diagram of generating a total pressure parameter according to an embodiment of the present application, where the sum of the static pressure and the dynamic pressure is equal to the total pressure. Therefore, in the case where the measurement point static pressure does not change from the initial point static pressure, that is, the measurement point static pressure is equal to the initial point static pressure. Based on this, one way is to sum the measured point dynamic pressure and the initial point static pressure to obtain the total pressure parameter of the measured point position. And in another mode, adding the dynamic pressure of the measuring point and the static pressure of the measuring point to obtain the total pressure parameter of the position of the measuring point.
In the case where the static pressure at the measurement point is changed from the static pressure at the initial point, since the total pressure is kept unchanged, if the dynamic pressure is increased, the static pressure is decreased. Conversely, if the dynamic pressure decreases, the static pressure increases. If the static pressure of the measuring point is changed compared with the initial static pressure of the measuring point, the dynamic pressure of the measuring point and the static pressure of the measuring point are needed to be summed to obtain the total pressure parameter of the position of the measuring point.
