step S620: inputting the flood discharge period data set into the initial monitoring scheme model to obtain an initial monitoring scheme;
step S630: and inputting the adjacent site water level difference data set, the adjacent site flow difference data set and the initial monitoring scheme into the correction scheme model to obtain a flood discharge period monitoring scheme.
Specifically, the monitoring scheme model is a functional model for generating a hydraulic engineering monitoring scheme, and comprises the initial monitoring scheme model and the correction scheme model. And the initial monitoring scheme model is a functional model which outputs a scheme for initial monitoring under the condition of not considering upstream and downstream influences according to flood discharge period data of the target hydraulic engineering. The model correction scheme is a functional model for correcting the initial monitoring scheme by considering a water level difference value and a flow difference value between adjacent stations and considering a real-time water regime. By combining the self factors of the target hydraulic engineering and the upstream and downstream influence factors, an accurate flood discharge period monitoring scheme is obtained. Therefore, the technical effects of improving the accuracy of the monitoring scheme, improving the intelligent degree of monitoring and shortening the monitoring period are achieved.
Step S700: and carrying out safety monitoring on the target hydraulic engineering according to the flood discharge period monitoring scheme.
Further, step S700 in the embodiment of the present application further includes:
step S710: when the target hydraulic engineering is in a non-flood discharge period, acquiring downstream jacking distance and water temperature information;
step S720: judging whether the downstream jacking distance exceeds a preset jacking distance or not, and if so, acquiring an initial non-flood discharge period monitoring scheme;
step S730: correcting the initial non-flood discharge period monitoring scheme according to the water temperature information to obtain a non-flood discharge period monitoring scheme;
step S740: and carrying out water conservancy monitoring on the target water conservancy project according to the non-flood discharge period monitoring scheme.
Specifically, the downstream jacking distance is the distance of water flow backflow when upstream incoming water meets the backflow after being blocked due to the fact that upstream incoming water is blocked by a downstream station by a flood prevention reservoir capacity, a large number of opened gates are provided, and a deep hole gate is arranged. Since the water level in the upstream water area is raised due to the backflow of the water flow, when the backflow distance exceeds the preset jacking distance, the monitoring of the target hydraulic engineering is influenced. Whereby an initial non-flood discharge period monitoring scheme is derived when the downstream jacking distance exceeds the predetermined jacking distance. Wherein the predetermined jacking distance is the maximum distance that downstream backflow will not affect target hydraulic engineering monitoring.
Specifically, the water temperature information is the temperature of the water flow at the target hydraulic engineering. When the water temperature is high, aquatic plants in the water area grow vigorously, the roughness of the river channel is increased, and the flood capability is reduced. Therefore, the initial non-flood-discharge period monitoring scheme needs to be modified according to the water temperature information to obtain the non-flood-discharge period monitoring scheme. Therefore, different monitoring schemes can be determined according to different periods of the target hydraulic engineering, and the technical effects of improving the monitoring accuracy and the monitoring efficiency are achieved.
