Embodiment Construction
[0033] Such as Figure 4 As shown, a method for detecting leakage of a water distribution pipe network includes the following steps:
[0034] Step 1: Detect the pressure value p of each node of the water distribution pipe network in a stable operation state (ie no leakage). The stable operation state refers to a change value of 0-2% in the total flow of the water distribution pipe network. The change value of the total flow of the water distribution network = maximum flow / minimum flow-100%.
[0035] Step 2: Detect the pressure value p of each node of the water distribution network in the leakage state (that is, the unstable operation state) 0 , the leakage state refers to the change value of the total flow of the water distribution network from 2.01% to 10%, and the change value of the total flow of the water distribution network=maximum flow / minimum flow-100%.
[0036] Step 3: Calculate the residual r of each node, r=p-p 0, the data of the residual r of each node is divide...
