Water supply network simulation experiment platform

Abstract

The invention provides a water supply network simulation experiment platform which comprises a pipe network system, an on-line data acquisition system, and a monitoring control and management operation system. The pipe network system is provided with two water supply tanks, pressurization water pumps, water inlet points, dozens of control flaps, and sensors of on-line pressure transducers and on-line flow sensors. The on-line data acquisition system acquires signal information of the pressure transducers, flow sensors and the like. The monitoring control and management operation system can realize control of stepless frequency conversion of two water pumps in a pipe network and display data acquired by the on-line data acquisition system in real time in forms of a number and a curve.

Description

technical field [0001] The invention relates to a simulation experiment platform, in particular to a water supply pipe network simulation experiment platform. Background technique [0002] The existing research ideas on the urban water supply network are as follows: according to the needs of the research, collect the basic data of the urban water supply network, establish a model of the pipe network on the basis of the collected data, and check it with the data of the operation of the pipe network Model, analyze and study the pipe network in the calibrated model. Due to the incompleteness of the basic data of the water supply pipe network, the collection of basic data requires a lot of manpower and material resources. At the same time, the incomplete accuracy of the basic data is limited, and there are different degrees of errors between the accuracy of the pipe network model and the actual pipe network. Can not accurately reflect the state of the pipe network. [0003] Th...

AI Technical Summary

Problems solved by technology

[0005] (1) The establishment of the physical model requires a large one-time investment and cannot be reused. Simulation experiments can only be performed on the original pipe network;

[0006] (2) The scale of the model is small, and there are few sensors for hydraulic and water quality monitoring. The simulation experiment can only record the experimental data manually;

[0007] (3) The same group of experimental data cannot be collected at the same time, and there is a large time difference between the data, which causes a large error to the experiment

[0008] (4) Since the data is recorded manually, the accuracy and precision of the data are limited, and the efficiency is relatively low
