According to the big data-based water affairs safety operation status inspection and management system of claim 5, it is characterized by: The safety assessment and analysis module includes a water conservancy line interval assessment unit and a comparison model anomaly analysis unit; the water conservancy line interval assessment unit retrieves the real-time water conservancy data matrix corresponding to each water conservancy operation section according to the current water conservancy operation line model to perform water conservancy operation status analysis on the corresponding section interval; performs a comprehensive water conservancy movement assessment on each section interval in combination with the water conservancy operation status value of each water conservancy operation section interval; constructs an assessment value relationship curve model within the period of each water conservancy operation section interval in combination with the period window; the comparison model anomaly analysis unit retrieves the assessment curve model of the same period of safe operation of each water conservancy operation section interval in the historical data; constructs a reference analysis model by taking the historical assessment curve model as a reference object and combining the assessment value relationship curve of each current water conservancy operation section interval; constructs a comparison curve model by mapping the historical data assessment curve and the current real-time assessment curve into the same reference system; performs a safety analysis on each current water conservancy operation section interval according to the comparison curve model; and judges the current state of the corresponding water conservancy operation section interval in combination with the safety assessment interval by setting a safety assessment interval.

7. The water affairs safety operation status inspection and management system based on big data according to claim 6 is characterized by: The abnormal feedback module includes a data feedback unit and an abnormal prompt unit; the data feedback unit visually annotates and feedbacks the safety assessment analysis data corresponding to each section of each water service line in the target area; the abnormal prompt unit gives priority to the line section assessed as abnormal and feeds back to the management port.
