Automated measuring complex for monitoring the level mode of channels and atmospheric parameters

The modern concept of irrigation development in the Russian Federation is based on research and development works on the creation of new irrigation equipment and technologies. Particular emphasis is placed on the widespread introduction of automation, energy saving, the possibility of using modern digital solutions. The introduction of automation on reclamation systems in Russia is constrained not only by the low level of their technical condition, but also by the signifi cant remoteness of automation facilities from power supply sources. The purpose of the research is to develop an automated measuring complex capable of monitoring the level mode of an open reclamation network, atmospheric pressure and temperature with data transmission to the server and subsequent analysis of monitoring data for user-defi ned conditions. The developed automatic measuring complex can work both from batteries and from a renewable energy source – solar panels. The schematic diagram of the complex and the results of experimental tests of the prototype in laboratory and fi eld conditions are given. The capabilities of a special computer program that analyzes monitoring data are described. The accuracy of measuring atmospheric pressure at a temperature of 25°C is ± 0.12 hPa. The accuracy of measuring the temperature of atmospheric air ± 1°C, measuring range lies within –40..+85°C. In the presence of wave phenomena and the absence of a fl oat well, the main absolute error in measuring the level is 0.02 m. In tests at a height of the installation from 0.4 to 2.0 m above the static water level, the main absolute error is 0.01 m.
