High-precision water level detection system

Abstract

The invention discloses a high-precision water level detection system. The high-precision water level detection system comprises an image acquisition module, a data transmission module, a water leveldetection terminal and an alarm module, wherein the image acquisition module is used for obtaining the overwater scale image and the position information of the overwater scale image, the obtained overwater scale image and the position information are transmitted to the water level detection terminal through the data transmission module, the water level detection terminal is used for carrying outimage processing on the overwater scale image so as to obtain the current water level value, and displaying the position information of the water level value and the water level in real time, and thealarm module is used for giving an alarm when the obtained water level value reaches a preset warning value. The high-precision water level detection system has the advantages that the image processing technology and the water level detection are combined, the defect that a person needs to check the scales on the marker post in the traditional method, the operation is inconvenient and the error islarge are overcome, the real-time and automatic detection of the water level is realized, so that the safety of water level detection is improved.

Description

technical field [0001] The invention relates to the field of water regime monitoring, in particular to a high-precision water level detection system. Background technique [0002] my country is a country with scarce water resources but frequent floods. Water monitoring has always been the focus of my country's water conservancy and agricultural departments. Traditional water level monitoring mostly uses manual monitoring of water levels. This method not only has personal safety problems for monitors , and the accuracy of the data cannot be guaranteed, and this method cannot realize real-time monitoring of the water level. As an important means of automation, informatization and intelligence, digital image processing technology has been widely used in industrial and agricultural measurement and production processes. The application of digital image processing technology to water level monitoring has attracted people's attention because of its advantages of rich information, i...
