[0100] Such as figure 1 As shown, a water supply network pipeline roughness coefficient and node water demand synchronous self-adaptive calibration method, the method includes the following steps:
[0101] (1) Collect water supply network monitoring data and initialize the self-adaptive calibration process;
[0102] (2) Based on the monitoring data of the water supply network, calculate the inference observation value of the node water demand at the current moment, and substitute it into the inference observation Kalman filter (IMKF) to calculate the optimal estimated value of the node water demand at the current moment;
[0103] (3) Calculate the inference observation value of the pipeline roughness coefficient at the current moment based on the monitoring data of the water supply network, and substitute it into the inference observation Kalman filter (IMKF) to calculate the optimal estimate value of the pipeline roughness coefficient at the current moment;
[0104] (4) Subs...
