s3: the current flow value and the target flow value are dynamically compared to schedule the feedback control pipe, the water flow in the main water supply pipe is scheduled, the electric control valve assembly on the adjusting pipe is controlled to compensate the flow based on the flow data of the branch pipe, and the flow value and the target flow value comparison data are generated;
s4: the data calculation module and the comparison scheduling module collect, calculate, analyze or generate data and store the data in the memory, and then feed back and adjust the waterway flow;
the process of S2 comprises the following steps: discretizing flow data of working days and rest days respectively, extracting discretized data of flow, and dividing a general time period and a fluctuation time period based on time corresponding to the discretized data;
extracting a characteristic value of the flow based on the discretized data of the general time period;
respectively calculating the characteristic values of the flow extracted by a plurality of groups of working days and resting days in the period according to time average to obtain standard values, and recording the standard values into flow fluctuation curves of the working days and the resting days respectively to form target flow values;
the process of S3 includes: comparing the current flow value with a target flow value corresponding to the current time, and taking the current target flow value as a flow standard value;
if the difference value of the current flow value and the target flow value corresponding to the current time is larger than the maximum value of the flow error, the current flow value is regulated to the target flow value corresponding to the current time by regulating and controlling a valve on a feedback control tube;
and acquiring flow data of a plurality of groups of branch pipes at present, determining the branch pipes with flow fluctuation, supplementing corresponding flow by an electric control valve assembly on the next regulating pipe of the branch pipes, generating corresponding compensation data at the same time, and supplementing the compensation data flow to the target flow of the time after recording a compensation period of a certain period.
