Embodiment Construction
[0030] In order to make the technical means and creative features of the present invention easy to understand, the implementation of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, without limiting the scope of rights of the present invention.
[0031] The water supply pipe network in this embodiment includes 22 common nodes, 3 water source nodes, and 37 pipe sections. Water is supplied to the pipe network through 3 water source nodes, 22 common nodes represent water for users, and 37 pipe sections represent transportation between nodes. aisle.
[0032] Such as figure 1 As shown, this embodiment includes the following steps:
[0033] Step 1 Determine the boundary of the low-lying area of the water supply network pressure
[0034] For low-lying areas with actual pressure, the EPANET simulation is used to obtain figure 2 Among the 22 nodes in the 24-hour node pressure, the nodes N5, N8, and N22 ...
