Arrangement method of pressure test points of water supply pipe network

Abstract

The present invention provides an arrangement method of pressure test points of a water supply pipe network. The arrangement method comprises the following two steps of partitioning the pipe network on basis of node pressure, and dividing nodes, positions of which are adjacent and pressure values of which are similar, into the same water supply sub area; and addressing the pressure test points of the pipe network by utilization of a sensitivity coefficient method for each water supply sub area so as to select the pressure test points from the nodes in the water supply sub areas. According to the arrangement method of the pressure test points of the water supply pipe network, the construction demand of a large-scale urban water supply pipe network can be satisfied, the calculating process of arrangement positions of the pressure test points is simple, and the calculated amount can be simplified.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage engineering, in particular to a method for arranging pressure detection points of a water supply pipe network. Background technique [0002] As we all know, the pressure monitoring points in the urban water supply network system generally refer to pressure recorders that use wired or wireless data transmission in real time. The purpose of setting pressure monitoring points in the pipe network is to monitor the operation status of the urban water supply pipe network in real time. In the case of satisfying the user's water pressure, according to the pressure value at the monitoring point, the operation mode of the water pump of the pumping station is reasonably adjusted to reduce the leakage of the pipe network and reduce the energy consumption of the pumping station. Therefore, arranging pressure monitoring points at appropriate locations in the urban water supply pipe network sy...

Problems solved by technology

However, the disadvantage of the above method is that the amount of calculation is too large. For example, for a large urban water supply network with 100,000 nodes, 100,000 adjustment calculations are required to obtain a sensitivity coefficient matrix of 100,000×100,000

Such a huge amount of calculation and data storage makes this method difficult to apply

The genetic algorithm also has defects. When the scale of the water supply network is large, the genetic algorithm is used for calculation, and the calculation time is too long to be practically applied.
