wherein the hydrometeorology collection system (141) is used for receiving the daily hydrometeorology data of the local hydrometeorology department and the meteorological department and uploading the data to the big data analysis system (142);
the big data analysis system (142) is used for analyzing and matching the acquired hydrographic meteorological data, classifying the hydrographic meteorological data into heavy rain, medium and light rain and sunny days, and transmitting the data to the smart cloud computing system (143);
the intelligent cloud computing system (143) is used for computing and determining the starting number of the water delivery pumps (6) after the data acquired in real time are matched with the flow of the water delivery pumps (6), and transmitting corresponding data to the instruction execution system (144);
the execution instruction system (144) is used for sending start and stop instruction signals to the configured water delivery pump (6).
10. A method of draining water across an obstacle in a system in which a raceway is to be spanned by an obstacle according to any one of claims 1 to 9, wherein: it comprises the following steps:
step 1): water in the water inlet pipe duct (3) enters from an inlet of the water collecting tank (2), and is accumulated in a grating room (2.1) of the water collecting tank (2) after garbage in the water is intercepted by a grating machine (7);
step 2): when the water level in the grid room (2.1) exceeds the height of the outlet of the water collecting pool (2), the intelligent cloud control system (14) controls the opening and closing mechanism to operate, the opening and closing gate (5) is lifted above the water level, water in the grid room (2.1) enters the pump gate pool (2.2), is discharged from the outlet of the water collecting pool (2), and then enters the downstream pipe channel (4);
step 3): when the water level in the grid room (2.1) is lower than the height of the outlet position of the water collecting pool (2) and higher than the set low water level of the pump gate pool (2.2), the intelligent cloud control system (14) controls one of the water delivery pumps (6) to start, and the water level in the pump gate pool (2.2) gradually rises and reaches the height of the outlet position of the water collecting pool (2) and then enters the downstream pipe channel (4);
step 4): when the water level in the grid room (2.1) is lower than the height of the outlet position of the water collecting pool (2) and reaches the high water level set by the pump gate pool (2.2), the intelligent cloud control system (14) controls the two water delivery pumps (6) to start, and the water level in the pump gate pool (2.2) gradually rises to reach the height of the outlet position of the water collecting pool (2) and then enters the downstream pipe channel (4).
