The execution subject of the present application may be a cloud server.
In one embodiment of the present application, different experimental water tanks are set in an experimental environment, and historical experimental data corresponding to the experimental water tanks is determined by performing a water injection experiment on the experimental water tanks, where the historical experimental data includes fluid speeds and pressures of an inlet of the water tank, an outlet of the water tank, and fluid speeds and pressures of respective unit control volumes obtained by dividing the total volume of the water tank into preset sizes (for example, 0.1 x 0.1). The unit control volume may have its center point as a node and the fluid velocity and pressure of the node as its corresponding fluid velocity and pressure. The water tank inlet and outlet and the fluid speed and pressure of each unit control volume can be acquired and measured by arranging sensors at corresponding positions of the experimental environment. In order to ensure the richness of data, historical experimental data are collected for the experimental water tanks with different volumes and different dead water area ratios, and two training sets, namely a first training set and a second training set, are divided according to two variables of the volumes and the dead water area ratios.
In one embodiment, the unit control volume is obtained by finite volume division of the test tank.
In one embodiment of the present application, the unit control volume may be obtained by a finite volume method, specifically, the finite volume method is that a water body is divided into a plurality of cubes which are very small and not repeated, each cube is called a unit control volume, each unit control volume is represented by a node, and a central point is generally selected as the node. The method is characterized in that the water body of the water tank is divided into a plurality of unit volumes by a limited volume method, and the fluid speed and the pressure of each unit volume are measured respectively, so that the overall water flow condition of the water tank is judged according to the data condition of each unit control volume, and further the dead water area and the non-dead water area of the water tank are determined.

In one embodiment of the present application, the hydrodynamic model may be built by openflow flow FLOOD software. The openflow FLOOD is comprehensive FLOOD simulation software, a complete spatial distributed digital model is used for simulating all hydraulic flows occurring in a river basin, the hydrodynamic model used in the method can be specifically represented by adopting a Navier-Stokes equation, the model is trained in the openflow FLOOD in sequence through a first training set and a second training set, after the model is ensured to be suitable for the conditions of different complexity, the model equation can be solved through specific boundary conditions (such as the fluid speed at the inlet and outlet of a water tank, the pressure, the shape volume of the water tank and the like), and the fluid speed and the pressure of each part in a given geometry are predicted.

S103, acquiring water tank data of the water tank to be tested, and importing the water tank data into the trained hydrodynamic model to obtain target parameter data corresponding to each target unit control volume in the water tank to be tested, wherein the water tank data comprise parameter data of an inlet of the water tank to be tested, parameter data of an outlet of the water tank to be tested and structure data of the water tank to be tested.
In one embodiment of the present application, the cloud server will acquire the water tank data of the water tank to be measured, and each item of data in the water tank data is the boundary condition used for model calculation. After the water tank data are imported into the hydrodynamic model, all parts in the water tank to be detected, namely target parameter data corresponding to all target unit control volumes, can be predicted through the hydrodynamic model.
S104, determining a dead water area and a non-dead water area of the water tank to be tested according to the target parameter data, determining the accumulated water age of the dead water area based on the historical water tank data of the water tank to be tested, and calculating the maximum water age of the non-dead water area based on the target parameter data.
In one embodiment of the application, the purpose of determining the water age of the water tank is to judge the water quality in the water tank according to the water age, so that the water supply safety is ensured, the water quality of a dead water area can be easily deteriorated after long time, the residual chlorine amount is reduced, germs are easily developed, and secondary pollution is caused. Therefore, the water tank is regarded as a whole to calculate the water age, and the obtained water age result is inaccurate and cannot be accurately represented by the actual state of the water tank. Therefore, according to the data of each target parameter, the fluid speed and the pressure of the corresponding position of each target unit control volume are determined, and the position with the fluid speed of 0 is the dead water area. Namely, according to the data of each target parameter, the dead water area and the non-dead water area in the water tank to be tested can be determined. After the dead water area and the non-dead water area are determined, the two water ages corresponding to the dead water area and the non-dead water area are used as the judgment basis of the safety of the water tank to be tested. Specifically, one is the dead water region accumulated water age of the dead water region, and the other is the maximum time that the running water of the non-dead water region takes from entering the water tank to leaving the water tank, namely the maximum water age of the non-dead water region.
In one embodiment, the determining the dead water area and the non-dead water area of the water tank to be tested according to each target parameter data includes:
Determining a first target unit control volume for which the fluid velocity is 0 and a second target unit control volume for which the fluid velocity is not 0 from each of the target parameter data;
and determining the region formed by the first target unit control volume as a dead water region of the water tank to be tested, and determining the region formed by the second target unit control volume as a dead water region of the water tank to be tested.
In one embodiment of the present application, from the fluid velocity in the target parameter data, a first target unit control volume having a fluid velocity of 0 and a second target unit control volume having a fluid velocity other than 0 can be determined. The region formed by all the first target unit control volumes is a dead water region, and the region formed by all the second target unit control volumes is a non-dead water region.
In one embodiment, the determining the accumulated water age of the dead water area based on the historical water tank data of the water tank to be tested includes:
and determining the accumulated time length of the water tank to be measured after the last water change based on the historical water tank data of the water tank to be measured, and taking the accumulated time length as the accumulated water age of the dead water area.
In one embodiment of the present application, for water in a dead water region, since the water velocity therein is 0, i.e., the body of water does not flow, the water age thereof should be the cumulative length of time that has elapsed from the last water change to the current time. The water changing operation of the water tank is generally required to be recorded, so that the time of the last water changing can be determined according to the historical water tank data of the water tank to be measured, and further the accumulated time length of the last water changing from the moment is determined, and the accumulated time length is the accumulated water age of a dead water area.
In one embodiment, the calculating the maximum water age of the non-dead water region based on the target parameter data includes:
dividing each second target unit control volume into a plurality of volume groups according to the section distance between the corresponding vertical section of each second target unit control volume and the inlet of the water tank to be tested, wherein the section distance between each second target unit control volume in each volume group is the same, the vertical section is formed according to the center point of the second target unit control volume, and the vertical section is perpendicular to the inlet and outlet connecting line of the water tank to be tested;
and respectively determining a third target unit control volume with the minimum fluid speed from each volume group, calculating the water flow movement time length corresponding to a water flow movement path formed by each third target unit control volume, and taking the water flow movement time length as the maximum water age of a non-dead water zone of the non-dead water zone.
In one embodiment of the present application, for flowing water in a non-dead water area, since the flow rates of water flows at various positions in the non-dead water area are different, the time of water in the non-dead water area retained in the water tank is also different, and considering water safety, the maximum water age of the non-dead water area needs to be determined under the condition that the water retention time is the longest, so as to be used as a safety judgment standard of the water tank to be tested. Considering that water flows in from the inlet of the water tank and flows out from the outlet of the water tank, the flow velocity is lower near the dead water region, and the dead water region is generally positioned far from the inlet and the outlet, it can be found that the lower the fluid velocity is, the closer the travel route is to the dead water region, and the longer the total length of the travel route is. Therefore, the maximum water age of the non-dead water area can be determined only by determining the time of the water body with the minimum fluid speed staying in the water tank in the water body of the water tank entering at the same moment. Specifically, a vertical section perpendicular to a connecting line of an inlet and an outlet of the water tank to be detected is generated according to the central point of each second target unit control volume, the second target unit control volumes are grouped according to the vertical section, a third target unit control volume with the minimum fluid speed is determined from each group, and a curve formed by connecting the central points of the third target unit control volumes is a water flow moving path of the water body which stays in the water tank for the longest time. Under the condition that the fluid speed of each third target unit control volume is known, the water flow moving time of the water body in the water flow moving path can be calculated by combining the water flow moving path, and the water flow moving time is the maximum water age of the non-dead water region.
In one embodiment, the taking the water flow moving duration as the maximum water age of the non-dead water area includes:
and acquiring pipe network line data corresponding to the water tank to be tested, determining the pipe network furthest conveying time according to the pipe network line data, and taking the sum of the water flow moving time and the furthest conveying time as the maximum water age of the non-dead water zone.
In one embodiment of the present application, since the water body needs to move in the pipe network line of the residential building after flowing out from the water tank outlet, the time taken for the water body to move in the pipe network line should also be considered in the maximum water age of the non-dead water region. Specifically, pipe network line data of the water tank to be detected are obtained, and the line path with the longest total path in the pipe network line and the average flow velocity of water flowing in the pipe network can be determined through the pipe network line data. According to the two data, the maximum conveying time length of the pipe network can be calculated, and the sum of the maximum conveying time length of the pipe network and the water flow moving time length is the maximum water age of the non-dead water region.
In one embodiment, the method further comprises:
when the accumulated water age of the dead water area is larger than a first preset water age or the maximum water age of the non-dead water area is larger than a second preset water age, warning information is sent to a target terminal corresponding to the water tank to be tested;
And when the accumulated water age of the dead water area is larger than a third preset water age or the maximum water age of the non-dead water area is larger than a fourth preset water age, sending closing control information to the water outlet electronic valve of the water tank to be tested.
In one embodiment of the present application, a first preset water age and a second preset water age are set for the dead water area and the non-dead water area, respectively, and generally, the first preset water age is smaller than the second preset water age, because germs in the dead water area need to be bred to a certain scale and then easily spread into the non-dead water area, thereby polluting the water source. If the accumulated water age of the dead water area is larger than the first preset water age or the maximum water age of the non-dead water area is larger than the second preset water age, the water age is considered to be too large, the water in the water tank to be tested has safety risk, at the moment, the cloud server can send warning information to a preset target terminal, and the target terminal can be a mobile phone terminal of residents of the residential building or a mobile phone/computer terminal of water tank maintainers. In addition, if no staff is still going to the water tank to be tested for maintenance after the warning information is sent, the water age can still be accumulated continuously. If the accumulated water age of the dead water area is larger than the third preset water age or the maximum water age of the non-dead water area is larger than the fourth preset water age, the water pollution is considered to be serious, closing control information is sent to the electronic valve of the water outlet of the water tank to be tested, the valve is controlled to be closed, and the water tank to be tested can not be opened again until maintenance is carried out on the water tank to be tested.
Next, a water age determining device of the secondary water supply tank according to an embodiment of the present application will be described in detail with reference to fig. 2. It should be noted that, the water age determining device of the secondary water supply tank shown in fig. 2 is used for executing the method of the embodiment shown in fig. 1 of the present application, for convenience of explanation, only the portion relevant to the embodiment of the present application is shown, and specific technical details are not disclosed, please refer to the embodiment shown in fig. 1 of the present application.
