供水管网系统用水模式确定与分析

Determination and analysis of water use model in water supply network system

用水模式制定是供水管网模型节点流量分配的重要步骤。主要阐述了城市供水管网系统用水模式制定的基本原则和方法,并对M市工程案例进行了示例分析,说明了用户分类过程中需注意的问题,提出采用GPRS机械远传表,可以实现数据的实时更新,保证了数据的可靠性,同时可为用水模式的制定打下基础,亦为供水管网模型精度的提高提供了有力支撑。

The formulation of water use model was the important step of node flow distribution in water supply network model. The basic principle and method of the formulation of water use model were introduced in urban water supply network system, the engineering case in M city was analyzed as an example, the issues during user classification were explained, adopting GPRS remote meter was put forward, real-time updating of data was achieved and the reliability of data was ensured. It could set up the foundation of the formulation of water use model, and provide effective support for the precision improvement of water supply network model.
