The infrastructure operation and maintenance system based on digital twins as claimed in claim 5, Features: The feedback module issues an operation and maintenance strategy according to the defect factors, distributes tasks according to the operation and maintenance strategy, generates and stores an operation and maintenance form, and uploads the operation and maintenance form to the display module; The generation logic of the operation and maintenance strategy of the water plant sub-site includes: When the defective pH value of the water plant sub-station is less than the lower limit of the pH value, the operation and maintenance strategy is to add alkaline agents until the pH value is distributed in the standard interval corresponding to the pH value; when the defective pH value of the water plant sub-station is greater than the upper limit of the pH value, the operation and maintenance strategy is to add acidic agents until the pH value is distributed in the standard interval corresponding to the pH value; When the defective dissolved oxygen amount at the front end of the aeration tank of the water plant sub-site is less than the lower limit of the dissolved oxygen amount, and the defective dissolved oxygen amount at the rear end of the aeration tank is greater than the lower limit of the dissolved oxygen amount, the operation and maintenance strategy is to increase the aeration amount and lay oil-absorbing felt; when the defective dissolved oxygen amount at the front end of the aeration tank of the water plant sub-site is greater than the upper limit of the dissolved oxygen amount, and the defective dissolved oxygen amount at the rear end of the aeration tank is less than the lower limit of the dissolved oxygen amount, the operation and maintenance strategy is to increase the sludge discharge and add heavy metal capture agent; when the defective dissolved oxygen amount at the front end of the aeration tank is less than the lower limit of the dissolved oxygen amount, and the defective dissolved oxygen amount at the rear end is less than the lower limit of the dissolved oxygen amount, the operation and maintenance strategy is to increase the aeration amount; When the defect conductivity of the water plant sub-station is greater than the conductivity upper limit, the operation and maintenance strategy is to clean the filter and increase the amount of sodium hydroxide added; When the defect turbidity of the water plant sub-station is greater than the upper limit of turbidity, the operation and maintenance strategy is to discharge the sludge in the sedimentation tank and reduce the outlet flow rate.

9. The infrastructure operation and maintenance system based on digital twins according to claim 7, Features: The generation logic of the operation and maintenance strategy of the pipe network sub-site includes: When the defect water pressure of the pipe network sub-site is less than the lower limit of water pressure, the operation and maintenance strategy is to increase the water supply pressure of the main network; when the defect water pressure of the pipe network sub-site is greater than the upper limit of water pressure, the operation and maintenance strategy is to reduce the water supply pressure of the main network; When the defect flow of the pipe network sub-station is less than the lower limit of the flow and the inner wall picture shows that the pipe network is damaged, the operation and maintenance strategy is to remove the sludge; when the defect flow of the pipe network sub-station is less than the lower limit of the flow and the inner wall picture shows that the pipe network is damaged, the operation and maintenance strategy is to repair the pipe network; when the defect flow of the pipe network sub-station is greater than the upper limit of the flow, the operation and maintenance strategy is to reduce the water supply pressure of the main network; The generation logic of the operation and maintenance strategy of the pump station sub-site includes: When the defective voltage of the pump station sub-site is not distributed in the standard range corresponding to the voltage, the operation and maintenance strategy is to shut down the power supply, troubleshoot the fault and perform repairs.

10. The infrastructure operation and maintenance system based on digital twins according to claim 1, Features: The display module is used to display the operation and maintenance form and the maintenance progress. The operation and maintenance form includes the employee number, maintenance time and maintenance sub-site label. The maintenance progress is obtained by the employee inputting in the system.
