智慧城市需要对供水网络进行交互式管理，水表在这一任务中发挥着重要作用。与全机械水表相比，机电水表或全电子水表可以通过自动抄表阅读（AMR）收集实时信息，这使得它们更适合智慧城市应用。在本文中，我们首先研究了现有的水表的设计原则，然后提出了我们的设计和实现的自供电智能水表。所提出的水表基于水涡轮机发电机，其用于两个目的：（i）通过对所产生的电压执行的自适应信号处理来感测水流;以及（ii）产生电力以给电池充电，从而使智能电表正常工作。特别是，我们提出的设计考虑和实施细节。无线收发器集成在所提出的水表，使它可以提供实时的水流量信息。此外，设计了一个移动的电话应用程序，为用户提供了一个方便的用水监测工具。
Smart cities require interactive management of water supply networks and water meters play an important role in such a task. As compared to fully mechanical water meters, electromechanical water meters or fully electronic water meters can collect real-time information through automatic meter reading (AMR), which makes them more suitable for smart cities applications. In this paper, we first study the design principles of existing water meters, and then present our design and implementation of a self-powered smart water meter. The proposed water meter is based on a water turbine generator, which serves for two purposes: (i) to sense the water flow through adaptive signal processing performed on the generated voltage; and (ii) to produce electricity to charge batteries for the smart meter to function properly. In particular, we present the design considerations and implementation details. The wireless transceiver is integrated in the proposed water meter so that it can provide real-time water flow information. In addition, a mobile phone application is designed to provide a user with a convenient tool for water usage monitoring.
