Embodiment

[0046] The average flow velocity of the cross-section measured in river flow observation can be regarded as the function of the flow velocity of the two major indicators of boat-borne ADCP and horizontal ADCP, and the linear relationship is the most basic function that reflects the relationship between multiple indicators. Therefore, the linear relationship between the vessel-borne ADCP and horizontal ADCP two index velocity and the average velocity of the cross-section measured by the channel discharge observation is revealed through the binary linear regression analysis.

[0047] Binary linear regression analysis forecasting refers to a forecasting method that uses two independent variables that affect a dependent variable for regression analysis. The key is to solve the regression equation through regression analysis of the causal relationship between the dependent variable and the two independent variables, and to test the regression equation to obtain the predicted value. ...

Abstract

The invention provides a river channel water flow real-time online monitoring method and device. A boat-mounted flow rate collection device is used for collecting flow rate data in the vertical direction of a river channel and transmitting the flow rate data to a GPRS wireless network, the flow rate data in the horizontal direction of the river channel is collected by a horizontal type flow rate collection device and transmitted to the GPRS wireless network by the horizontal type flow rate collection device, the water level data of the river channel is collected by a water level collection device and transmitted to the GPRS wireless network by the water level collection device, the GPRS wireless network is connected with the Internet network and transmits the flow rate data in the verticaldirection of the river channel, the flow rate data in the horizontal direction of the river channel and the water level data of the river channel to a central station through the Internet network, and analysis and storage are conducted on the received data by the central station, so that river channel water flow real-time online monitoring is achieved, obtained data information is processed in real time simultaneously, and the current river channel water flow data is obtained by conducting real time analysis and computing.

Description

technical field [0001] The invention relates to a real-time on-line monitoring device for river flow, which belongs to the technical field of hydrological monitoring. Background technique [0002] Flow data play an extremely important role, involving various aspects such as flood control safety, hydrological and hydraulic calculations, and water resource evaluation. Therefore, river flow measurement is an important part of hydrological work, and a large amount of manpower and material resources are required to complete the test task every year. In order to reduce the workload of flow testing, hydrologists have long been looking for ways to reduce the number of flow tests, shorten the test duration, or indirectly measure the flow by monitoring the water level, water level fluctuation rate, drop (or water surface gradient), or Directly adopt the method that can automatically measure the flow rate. These methods take a long time and have a low degree of automation, and are inc...
