AI Technical Summary

Technical Problem

The existing water supply pipeline node initialization method has many shortcomings, including cumbersome data links and maintenance, the inability to accurately reflect real-time water use changes, and the inability to accurately reflect water use needs at different times in areas with high population mobility.

Method used

The water demand initialization method of water supply pipeline nodes based on dynamic population distribution is adopted. By calculating the number of populations in each online metered water meter service area and the number of populations in each grid unit in real time, combined with the data of the mobile signaling data platform, the dynamic population number of each node service area is accurately determined at each moment, thereby initializing the water demand of water supply pipeline nodes.

Benefits of technology

It improves the accuracy of population movement analysis, can accurately reflect population dynamics and its impact on water demand, and makes the initialization of node water demand more in line with the actual situation, and is suitable for complex urban water supply systems with high population mobility.

Abstract

The invention belongs to the technical field of hydraulic model correction, and aims to solve the problems that the current bottom-up method is tedious, time-consuming and difficult to reflect real-time water consumption change and the node water demand obtained by the top-down method is not consistent with the actual condition. The invention provides a dynamic population distribution-based water supply network node water demand initialization method, which comprises the following steps of: calculating the population number in each online metering water meter service area and the population number in each grid unit in a water supply range at the current moment based on a mobile phone signaling data platform; and calculating the population number of off-line metering water in each water supply grid unit at the current moment, and then initializing the node water demand of the water supply network at the current moment based on the on-line metering water data at the current moment and the population number of off-line metering water in each node service area. According to the method, the population dynamics and the influence of the population dynamics on the water demand can be accurately reflected, so that the node water demand initialization in the high population flow area is more in line with the actual situation.
