Intelligent device for measuring water level in irrigation channels of constant section
Abstract
The article discusses the problems of online monitoring of water metering in the irrigation systems of Central Asia, in particular the Republic of Uzbekistan, and identifies existing problems. The development of intelligent level measurement devices is aimed at solving these problems. A technique has been created for developing an intelligent level measurement device capable of operating stably even under various disturbing influences, considering abrupt climate changes. Based on this method, an intelligent device has been developed that allows online measurement of the water flow and its amount flowing in the channel based on measuring the water level in channels with a constant cross-sectional area. The device has the function of automatic selection of alternative networks for the exchange of information, such as GSM or Lora, depending on the conditions of information transmission over long distances. The device also includes the function of autonomous charging using solar energy in places with no power supply. The industrial sample of the device was tested and certified in laboratory and field conditions and at the National Certification Center of the Republic of Uzbekistan, and permission was obtained for its mass production. Because local manufacturers produce this device, it has advantages over its imported counterpart in terms of low cost, the availability of customization options, and easy adaptation to difficult conditions. In exchange for applying a smart filtering algorithm, the stabilization of received signals is improved by 74.2% due to intelligent filtering algorithms in a smart device. The reliability of information decreased by 8.2% in total. This result is less than the 9.5% target for information reliability.
