新型智能流速流量仪系统设计

System Design of a New Type Intelligent lnsintment for Flow Velocity and Discharge

为满足水文部门对河流流速流量测量多种的要求，在转子式流速仪基础上，设计了1款智能流速流量仪系统，介绍了该仪表的原理，软硬件设计方法，设计了上位机系统。应用表明，该流速流量仪提高了测量精度和测量数据的时效性，实现了水文数据的无纸记录，提高了工作效率和水文数据信息化管理水平。

For the sake of satisfying multiple requirements for flow velocity and discharge measurement, an intelligent instrument was developed on the basis of rotating-element current meter.The thesis introduces its principle, design method of software ＆ hardware.Its application indicates that the instrument system increases measurement precision and timeliness of measured data, realizes paperless recording for hydrological data, improving work efficiency and hydrological data informatization management level.
