Description

technical field [0001] The invention relates to the field of hydraulic technology monitoring, in particular to a navigable hydraulic element sensing terminal system and a calculation method thereof. Background technique [0002] The monitoring of the hydraulic elements of large rivers has always been the basic work of hydrological monitoring, and it is also an important basic support for the research and decision-making of the hydrodynamic water environment and water resources of large rivers. At present, the monitoring of hydraulic elements of large rivers, especially the measurement of flow, velocity and river section, is divided into fixed type and mobile type. The mobile type often requires manual navigation measurement, that is, the use of artificial boats tow and monitor equipment to navigate along the longitudinal section of the river channel. This measurement method is time-consuming and laborious, and when measuring typical working conditions (such as floods, storm ...

AI Technical Summary

Problems solved by technology

The mobile type often requires manual measurement of the navigation type, that is, the use of artificial boats tow and monitor equipment to navigate along the longitudinal section of the river. This measurement method is time-consuming and laborious, and when measuring typical working conditions (such as floods, storm surges), There are still certain risks; in addition, various equipment are operated alternately, which requires relatively high technical and operational capabilities of the personnel on board

For the fixed measurement, the flow rate can only be reversed by the water level, which requires a lot of pre-calibration work, and with the change of the river topography, in order to ensure the measurement accuracy, it is necessary to carry out the complex rate. In addition, the fixed measurement is in the There are certain technical difficulties in measuring the structural shape of the channel section

[0003] In addition, the parameters calculated in traditional hydraulic element monitoring devices are generally fixed. When the monitored hydraulic environment changes, the value of the parameter cannot be changed in real time according to the change of the environment, resulting in inaccurate monitoring of hydraulic elements and poor adaptability.
