In order to solve the present river velocity measurement system which uses cable, and has low anti-interference ability, system flexibility and signal attenuation, this paper builds an intelligent river velocity acquisition system to realize automatic acquisition point velocity. The system uses the ZigBee network structure, and the control center computer is connected to ZigBee coordinator, flow velocity collection device connected to the ZigBee terminal, and at last realizes the velocity data acquisition and data transmission. The system realizes automatic elimination of propeller current error data with the analog time series of velocity data, and generates flow cross section measurement transformation matrix according to the flow velocity instrument layout information, so that the problem of the velocity data and the actual measured flow point matching is solved. System separates velocity data and data processing to improve the efficiency of experiment and data processing. Practice application shows that, the flow velocity collection system can meet the needs of large model of river flow velocity collection, the system is flexible and accurate. [ABSTRACT FROM AUTHOR]
