the water line will be described first with reference to fig. 2: highest water level line H allowed by channel operationmax: generally, the water level is not more than 98% of the highest water level of the channel design so as to improve the safety of water level early warning. Early warning starting water level line Hswl: the warning high water level of the channel operation, when the water level reaches the early warning starting water level line, the server sends out a high water level early warning signal, the water level line can be set reasonably according to engineering operation experience, and generally the water level line is not more than 85% of the highest water level of the channel design. Early warning water level line Hawl: generally, the median value of the allowable highest water level line and the early warning starting water level line is taken as an early warning water level line; when the water level rises to the early warning water level line, the server sends out a high water level warning signal, and the server issues a high water level red warning signal every time the water level rises by delta h.
The water level meter 1 and the network camera 2 are arranged at the bottom and/or the side wall of the channel along the water level line and are connected with the server 9, so that the real-time monitoring of the water level of the channel and the running image of the channel is realized, and the processor in the terminal 10 receives the water level data sent by the server 9 to continue the meterAnd (4) calculating to obtain the water level increasing rate v.

The display medium of the terminal 10 and the mobile terminal 11 display alarm information.
And (3) early warning and judging water level rate: when the processor obtains the velocity v in the range: v1＜v≤V2The time is first-level early warning, and the server issues a blue warning signal; when the processor obtains the velocity v in the range: v2＜v≤V3For the second-level early warning, the server issues a yellow warning signal; when the processor obtains the velocity v in the range: v > V3For three-level early warning, the server issues a red emergency alarm signal. The display medium of the terminal 10 and the mobile terminal 11 display alarm information.
Under the condition of high water level and/or when the water level rate reaches the rate alarm standard, as shown in fig. 4, the server sends a gate opening adjustment instruction to the processor of the terminal 10, and the control end of the processor drives the opening and closing control module of the gate 7 through a pre-laid cable.
