重力式流速传感器及其明渠流速流量监测装置

Gravity Type Velocity Sensor and Velocity of Flow in Open Channel Flow Monitoring Devices

过水建筑物中水流流速的监测,在水利工程的运行管理工作中有着重要的意义,它为防汛抗旱调度指挥工作提供参考数据。为了实现水利基础设施的物联网化,需要有结构简单、经济实用的流速传感器及其流量监测装置。为此,提出了一种根据流体阻力方程,利用三轴加速度传感器间接测量水流流速的重力式流速传感器。并且在此基础上设计的依靠GSM/GRPS技术传输数据的流量监测装置,此装置将能够满足水利设施运行管理的实际监测需要。

Water flow monitoring of hydraulic structure is significant in the water conservancy project＇s operation and management . And it provides reference data for scheduling the command of flood control and drought relief .In order to internetize things about water infrastructure ,there must be some practical velocity sensors and flow monitoring devices which are simple and economical .To this end ,a new kind of velocity sensor has been put forward according to the fluid resistance equation and three axis acceleration sensor is used to calculate velocity ,by named gravity flow velocity .And based on this ,a kind of flow monitoring device depending on GSM /GPRS technology to transmit data is designed ,which will meet the needs of the actual monitoring .
