Problems solved by technology

This method has its advantages, but the cost is higher
[0005] Moreover, the existing water level monitoring devices can only detect the water level alone, but cannot detect the water quality, and need to use another water quality monitoring device to realize it. How to realize the simultaneous measurement of water level and water quality is a technical problem in this field

Abstract

The invention relates to a water regimen monitoring method for monitoring the water quality by virtue of a gray level detection theory. A water regimen monitoring system adopted in the water regimen monitoring method comprises a measurement pipe, a video collection system and an image processing module, wherein a lower port of the measurement pipe is used for penetrating into the water surface, a photographing device is arranged right above an upper port of the measurement pipe and is used for photographing water surface images in the measurement pipe; the video collection module is connected with the camera and is used for converting collected images to digital images; the image processing module is connected with the video collection module and stores first sample data, and gray values of various water qualities are recorded in the first sample data; and the image processing module is used for carrying out gray level processing on the digital images so as to obtain the gray level values of the water surface images and making comparison on the gray values and the first sample data so as to obtain the water quality conditions. According to the water regimen monitoring method, the corresponding conditions of the water quality can be obtained by the virtue of the water surface images. The water regimen monitoring system is simple, can be used for carrying out convenient and fast water quality measurement or prejudgment in the open air or without water quality test conditions, and complex steps are omitted.

Description

technical field [0001] The invention relates to the field of electronic measurement, in particular to a water regime monitoring system. Background technique [0002] Among the water level measurement methods in the prior art, the float type water level gauge is most commonly used in water regime monitoring. Hang the float vertically on a pulley with a line, and when the float is placed on the water surface, it will move up and down as the water level rises and falls. The current water level can be obtained through the distance between the float in the pipe and the designated point, and through certain calculations. Float water level gauge requires special logging. Its disadvantage is that it is more complicated to install. At the same time, if the water flow contains heavy sediment, after a period of operation, the logging inlet pipe will produce siltation, which is easy to form a false water level. [0003] The pressure water level gauge is based on the hydrostatic pressu...
