[0015] As Figure 1 shown, an infrastructure management system based on big data includes a main control center, and the main control center is communicatively connected with a map construction module, a data collection module, a first processing module, a second processing module, a fault monitoring module, and an information feedback module; The map construction module is used to construct a visual map of urban drainage outlets by using GIS technology; The data collection module is used to collect and store the drainage velocity and drainage flow rate of urban drainage outlets; The first processing module is used to obtain the drainage states of the drainage velocity and drainage flow rate, adjust the drainage equipment according to the obtained drainage states, and obtain the drainage coefficient of urban drainage outlets, and select whether to carry out coordinated drainage according to the obtained drainage coefficient; The second processing module is used to obtain the change trend of the drainage coefficient and pre-adjust the drainage equipment according to the obtained change trend; The fault monitoring module is used to construct a digital twin model of urban drainage outlets, obtain the theoretical adjustment change diagram and the actual adjustment change diagram of the drainage equipment, judge whether there is a fault in the drainage equipment according to the comparison result of the two change diagrams, and generate equipment fault information; The information feedback module is used to feedback the generated equipment fault information to the staff.

[0016] It should be further noted that in the specific implementation process, the process of the map construction module constructing a visual map of urban drainage outlets by using GIS technology includes: Set up a map construction unit to collect the basic information of urban drainage outlets through the map construction unit. The basic information includes but is not limited to urban terrain data, rainwater drainage network data, sewer network data, building and road data; Use GIS technology to construct a visualization map of urban drainage outlets based on the collected basic information of urban drainage outlets. Staff can view the constructed visualization map through a mobile terminal. At this time, the constructed visualization map only includes the basic information of urban drainage outlets and does not include other data of urban drainage outlets.

[0017] It should be further noted that in the specific implementation process, the process of the data acquisition module collecting and storing the drainage velocity and drainage flow of urban drainage outlets includes: The urban drainage outlet needs to include at least two drainage devices, namely a gate and a drainage pump. A flow velocity monitoring unit is set at the gate to collect the drainage velocity of the urban drainage outlet through the flow velocity monitoring unit, and the collected drainage velocity is marked as S. A flow monitoring unit is set at the drainage pump to collect the drainage flow of the urban drainage outlet through the flow monitoring unit, and the collected drainage flow is marked as L; Set up a database. The main control center audits the collected drainage velocity and drainage flow, uploads the audited drainage velocity and drainage flow to the database for storage, and simultaneously uploads the stored drainage velocity and drainage flow to the visualization map for synchronization.

[0018] It should be further noted that in the specific implementation process, the process of the first processing module obtaining the drainage state of the drainage velocity and drainage flow and adjusting the drainage device according to the obtained drainage state includes: Obtain the drainage velocity and drainage flow of all urban drainage outlets at the same moment, mark the average value of the drainage velocity and drainage flow of all urban drainage outlets as the velocity average value and flow average value at this moment, and mark the obtained velocity average value and flow average value as S 均 and L 均 ; Taking the drainage velocity as an example, obtain the corresponding velocity range according to the obtained velocity average value, and mark the obtained velocity range as [S 均 -s, S 均 +s], where s is a preset fixed value. Compare the obtained drainage velocity with its corresponding velocity range, and mark the drainage velocity as different drainage states according to the comparison result; If S < S 均 -s, then mark it as a low velocity state. If S 均 -s ≤ S ≤ S 均 +s, then mark it as a high velocity state. If S > S均 If it is +s, it is marked as the high flow rate state; There are three levels of opening degrees set inside the gate, namely the first opening degree, the second opening degree, and the third opening degree. Among them, the first opening degree is less than the second opening degree which is less than the third opening degree. There are three levels of drainage powers set inside the drainage pump, namely the first drainage power, the second drainage power, and the third drainage power. Among them, the first drainage power is less than the second drainage power which is less than the third drainage power; Taking the drainage flow rate as an example, for the drainage flow rate in the low flow rate state, set the opening degree of its gate to the first opening degree. For the drainage flow rate in the medium flow rate state, set the opening degree of its gate to the second opening degree. For the drainage flow rate in the high flow rate state, set the opening degree of its gate to the third opening degree; And so on, use the same method to obtain the flow rate range [L 均 -l, L 均 +l], where l is a preset fixed value, and mark it as different drainage states, including the low flow state, the medium flow state, and the high flow state. Set the corresponding drainage power for the drainage flow rate in different drainage states, and at the same time upload the obtained drainage state, the opening degree of the drainage equipment, and the drainage power to the visualization map for synchronization.

[0019] It should be further noted that in the specific implementation process, the process by which the first processing module obtains the drainage coefficient of the urban drainage outlet and selects whether to perform collaborative drainage based on the obtained drainage coefficient includes: Set drainage weights for the drainage flow rate and the drainage flow volume obtained at the same moment respectively. Set the drainage weight of the drainage flow rate to Q s , and set the drainage weight of the drainage flow volume to Q l , obtain the drainage coefficient of the urban drainage outlet at this moment, and mark the obtained drainage coefficient as P;

[0020] Set the drainage threshold P 0 , compare the obtained drainage coefficient with the set drainage threshold, and select whether to perform collaborative drainage according to the comparison result. If P < P 0 , then do not perform collaborative drainage. If P ≥ P 0 , then perform collaborative drainage; For urban drainage outlets that require coordinated drainage, a circular area with a radius of a preset distance R is constructed centered on it. All other urban drainage outlets within this circular area are regarded as the coordinated drainage outlets of this urban drainage outlet. The opening degrees of the gates and the drainage powers of the drainage pumps of all coordinated drainage outlets are increased by one level to achieve coordinated drainage. After the drainage coefficient drops below the drainage threshold, it is restored to its original level.

[0021] It should be further noted that in the specific implementation process, the process of the second processing module obtaining the change trend of the drainage coefficient and pre-adjusting the drainage equipment according to the obtained change trend includes: Set an evaluation period, mark the evaluation period, denoted as k, where k = 1, 2,.... It should be further noted that in the specific implementation process, k represents the current evaluation period, and k - 1 represents the previous evaluation period; When an evaluation period is reached, record the obtained drainage coefficient, and mark the recorded drainage coefficient as the evaluation coefficient, denoted as P k , obtain the change coefficient of the drainage coefficient based on the evaluation coefficients within the most recent k evaluation periods, and denote the obtained change coefficient as B Pk ;

[0022] Set the change threshold B P0 , compare the obtained change coefficient with the set change threshold, and obtain the change trend of the drainage coefficient according to the comparison result. The change trend includes a downward trend and an upward trend; When |B Pk - B Pk-1 | ≤ B P0 , mark it as a normal change; When |B Pk - B Pk-1 | > B P0 , mark it as an abnormal change, and compare the parameter values of P k and P k-1 ; When P k < P k-1 , mark the drainage coefficient as a downward trend; When P k > P k-1 , mark the drainage coefficient as an upward trend; For the drainage coefficient with a downward trend, reduce the opening degrees of its gates and the drainage powers of its drainage pumps by one level. For the drainage coefficient with an upward trend, increase the opening degrees of its gates and the drainage powers of its drainage pumps by one level. At the same time, upload the obtained drainage coefficient and change trend to the visualization map for synchronization.

[0023] It should be further noted that in the specific implementation process, the process by which the fault monitoring module constructs a digital twin model of the urban drainage outlet and obtains the theoretical adjustment change diagram and the actual adjustment change diagram of the drainage equipment includes: Set up a model construction unit to collect the equipment information of the drainage equipment through the model construction unit. The equipment information includes the specification parameters, process parameters, historical data, environmental data, and maintenance data of the drainage equipment; Construct a physical model of the drainage equipment according to the obtained specification parameters and process parameters, construct a behavior model of the drainage equipment according to the obtained historical data, environmental data, and maintenance data, and integrate the constructed physical model and behavior model to obtain a digital twin model of the drainage equipment; In the digital twin model, when the drainage equipment starts to be adjusted, monitor the drainage flow rate, drainage volume before, after, and during the adjustment. Taking the drainage flow rate as an example, construct a theoretical adjustment change diagram with the horizontal coordinate being time and the vertical coordinate being the drainage flow rate according to the monitored drainage flow rate. Use the same method to monitor the drainage flow rate in the actual situation and construct the corresponding actual adjustment change diagram. Use the same method to obtain the theoretical adjustment change diagram and the actual adjustment change diagram of the drainage volume.

[0024] It should be further noted that in the specific implementation process, the process by which the fault monitoring module determines whether there is a fault in the drainage equipment according to the comparison result of the two change diagrams and generates equipment fault information includes: Taking the drainage flow rate as an example, compare the theoretical adjustment change diagram and the actual adjustment change diagram of the drainage flow rate. If the actual adjustment change diagram can adjust the drainage flow rate to the level of the theoretical adjustment change diagram, it is determined that the gate is free of faults. If not, it is determined that the gate has faults and generates a type I fault information. If the time required for the actual adjustment change diagram to make the adjustment is the same as that of the theoretical adjustment change diagram, it is determined that the gate is free of faults. If different, it is determined that the gate has faults and generates a type II fault information; And so on, use the same method to compare the theoretical adjustment change diagram and the actual adjustment change diagram of the drainage volume, determine whether there is a fault in the drainage pump according to the comparison result, and generate the corresponding type III fault information and type IV fault information. The type I fault information, type II fault information, type III fault information, and type IV fault information all belong to the equipment fault information.

[0025] It should be further noted that in the specific implementation process, the process by which the information feedback module feeds back the generated equipment fault information to the staff includes: Feedback the generated device fault information to the staff, and the staff will further process the drainage equipment according to the obtained device fault information. The device fault information includes the first-class fault information, second-class fault information, third-class fault information, and fourth-class fault information.
