Water Meter ID Identifying and Reading System Based on RFID Technology

In order to achieve the intelligent water meter reading, a water meter ID identifying and reading system based on RFID technology has been designed. Because most of water meters are made by foundry iron, the transmit signals will be interfered with the iron if we use ordinary UHF tags. To solve this problem, the system uses anti-metal UHF tags as the data transmitter and hand-held data reader as the Data receiver. Furthermore, ISO18000-6C is selected as the Radio-Frequency Identity protocol. As a result, the communication distance can reach more than 1 meter in the proposed system, which provides a solution for intelligent water meter reading and data saving in database.
