Water supply pipeline gateway valve method based on binary multi-objective particle swarm optimization algorithm

Abstract

The invention discloses a water supply network valve closing method based on a binary system multi-target particle swarm algorithm. The method comprises the following steps: firstly delimiting a searching area according to an abnormal position; secondly, finding out valves inside the searching area, including the positions and number of all the valves; then determining a binary system multi-target particle swarm algorithm optimization model, carrying out initial population and encoding, and determining particle initial valve and particle speed and updating the position, wherein each valve corresponds to one particle, the position of each valve corresponds to the position of the corresponding particle; and finally solving the optimization model to generate a valve closing scheme. A water supply network valve closing scheme can be quickly and effectively determined under abnormal conditions so as to isolate abnormal points, and compared with a valve closing scheme determined by graph paper inquiry of a dispatcher in dependence on experience, the valve closing speed and accuracy are improved, and a great deal of manual check consumed by the establishment of a network topology mechanism for valve closing particularly for GIS software is avoided.

Description

Technical field [0001] The invention belongs to the field of urban water supply, and specifically is a water supply pipe gateway valve method based on Binary Multi-Objective Particle Swarm Optimization (BMOPSO). Background technique [0002] Abnormal situations such as pipe bursts and leaks are common in the water supply network. The uncertainty, suddenness, large scale of the pipe bursts, and the long duration, imperceptibility, and small scale of the leakage will affect daily industrial production, Residential water use has a huge impact. Therefore, how to find a fast and effective valve-closing method has important significance and effect on the treatment and smooth operation of the water supply network under abnormal conditions. [0003] However, the actual topological structure of the water supply pipe network is complex, the pipes are intertwined, and there are many types of valves. Therefore, it is difficult to determine a fast and effective valve closing program. At prese...

Problems solved by technology

The former is slow, the workload is heavy, and the accuracy is poor. It is easy to misjudge the gateway valve due to human factors, which makes the valve closing scheme not applicable to the actual situation; the latter is because many commonly used GIS software does not have a network topology mechanism. Therefore, Close valve analysis is inefficient and inaccurate

If the GIS software specifically establishes the network topology mechanism, it will take a lot of manual checking
