Urban area drainage basin intelligent connected draining and connected dispatching method

The invention discloses an urban area drainage basin intelligent connected draining and connected dispatching method. The method comprises the steps of 1, monitoring the last reach water level for each urban area drainage dispatching sluice gate station; 2, when the last reach water level of any drainage dispatching sluice gate station is raised to be higher than a warning value or it is predictedthat the last reach water level is about to reach the warning value within 4 hours, starting a sluice pump of the drainage dispatching sluice gate station; 3, when the last reach water level of any drainage dispatching sluice gate station is reduced to be lower than the warning value or when a sluice pump of an upstream dispatching sluice gate station adjacent to the dispatching sluice gate station is in the closed state and the last reach water level of the drainage dispatching sluice gate station is lower than the warning value, closing the sluice pump of the drainage dispatching sluice gate station.
