An automatic monitoring device and method for river flow ice density

Abstract

The invention discloses a river channel drift ice density degree automatic monitoring device and method. The monitoring device comprises a remote terminal unit which is connected with a holder, a laser range finder, a water level gauge and a wireless communication module, wherein the laser range finder is installed on the holder, a storage battery is connected with a solar panel through a charge controller, the storage battery provides a power supply for the remote terminal unit and the holder, and all the devices, except the water level gauge, of the monitoring device are installed on a floodwall corresponding to a tested cross section to measure the drift ice density degree. The monitoring device can automatically monitor the river channel drift ice density degree, no manual work is involved, measurement is not influenced by light, and continuous online measurement can be achieved in the daytime and at night. The method is higher in measurement accuracy compared with an existing method, and is easy to implement.

Description

technical field [0001] The invention relates to an automatic monitoring device and method for river flow ice density. Background technique [0002] The river flow ice density refers to the ratio of the plane area of ​​ice cubes and ice flakes to the exposed water surface area in the tested river section. The phenomenon of river ice regime is an important feature of northern rivers. The purpose of ice observation is to grasp the icing situation of rivers, understand the change law of ice snow, and provide necessary information for exploring and analyzing the hydrological phenomena and laws of ice age. Serve for the development of national economy such as water conservancy project construction and transportation. [0003] A large amount of drift ice is formed in the northern rivers before freezing and during the thawing period. The purpose of the ice flow test is to understand the amount of drift ice in the river and calculate the total amount of ice. [0004] The measuremen...

Problems solved by technology

[0009] The above-mentioned density measurement method needs to rely on observers to participate in the estimation and judgment throughout the process. It is very random and must have sufficient light for human eyes to see. It is almost impossible to complete the measurement at night, and it is difficult to achieve continuous online monitoring during the day.
