| Abstract: | In view of the Ningxia Hui Autonomous Region water conservation informationization construction＇s demand, the monitoring system and network are proposed, which use the existing GPRS net to establish water conservation data acquisition and long-distance real-time monitor. Its data system can be connected to Internet, achieving the goal of Ningxia water resources informationization management. A design proposal of ultrasonic wave open channel flowmeter based on the GPRS is proposed, which uses the principle of time difference method. The flowmeter＇s hardware architecture and the design proposal are accomplished, moreover, the research and design of GPRS DTU are accomplished. |
