Results:
1 An algorithm has been developed for a programmable logic controller (PLC) that ensures compliance with the technical requirements for the shutter, performed on time and within the development budget, as well as meeting safety requirements. The algorithm is implemented in the TIA Portal environment and includes functional blocks for measuring the level and position of the shutter, total water flow metering (TOTALIZER) and PID regulation of the shutter position (PID _ 3Step), as well as emergency protection and manual control mode..
2 The required quantity of materials and components was received in accordance with the technical requirements, within the established time frame and within the procurement budget, the receipt of high-quality materials and components from reliable suppliers was ensured.
3 The main elements and principle of operation of the model were determined, compliance of the schematic diagram with the technical requirements for the shutter was established, as well as its compliance with applicable codes and standards. The circuit contains AC/DC redundant power supplies and protection devices (circuit breakers, USIP, fuses), grounding and shielding circuits, filtering and interference isolation, as well as emergency stop, boundary position interlocks and system monitoring circuits (drive current, sensor status).
4 The accuracy of the technical requirements for the user interface and database, as well as for the systems for controlling the shutter, collecting and analyzing data on its operation is determined. A user interface (HMI) and a database structure for an automated hydraulic shutter have been developed, taking into account the tasks of operational management, accounting and analytics; the interface is made in WinCC for the TP700 Comfort panel and includes the main screens – Main (control and status), Archive (monthly and total volume accounting), Historical (trends and graphs), Settings (PID parameters and calibration coefficients) and Alarm/Events (log of accidents and events). HMI provides convenient controls (automatic/manual/setting modes), digital and linear indicators of the level/flow/shutter position, control buttons, fields for setting settings and an adder reset button; screens for diagnostics of sensors and drive state, monitoring of power supply and emergency protection modes are implemented.
5 Serviceability of the shutter in various operating modes is determined, possible malfunctions and errors in its functioning are revealed, recommendations for their elimination are developed. In laboratory conditions, comprehensive experimental work was carried out to assess the performance of a prototype of an automated hydraulic shutter: functional tests of PLC logic (modes – automatic, manual, emergency), adjustment and debugging of the PID regulator, verification of signal scaling and volume calculation algorithms (TOTALIZER) were performed. The tests were accompanied by continuous recording of process parameters (level, flow rate, gate position, drive current/voltage, events) with a frequency of 1 Hz and subsequent statistical processing (assessment of MSE, confidence intervals, transient time).
6 The effectiveness of the shutter was assessed, recommendations for its improvement were developed, the shutter was approved for mass production. Experiments were carried out in full-scale conditions on irrigation systems of the Turkestan region in order to check the operability of the automated hydraulic shutter in real operating conditions. The prototype was installed on one of the distribution channels, equipped with water level and flow sensors, an electric drive and a Siemens S7-1200 controller with an HMI interface (TP700 Comfort). During the experiments, the system was operated in various modes – automatic, manual and mixed – with varying hydraulic flow parameters. Observations were made on the accuracy of maintaining the given water level in the pool, the speed of the system response to disturbances, the stability of the PID regulator, the reliability of the measuring channels and the correctness of the total accounting of the supplied volume of water.
7 Professional development of specialists in operation of the automated hydraulic gate was organized, understanding of technical features and principles of its operation was improved, risks of accidents and incidents during operation were reduced. In the Turkestan region, a training seminar was held on the operation of an automated hydraulic shutter on irrigation systems. The event was attended by specialists from water farms, representatives of irrigation departments and operational organizations.

10 A complete and accurate analysis of the results of the experiment was carried out, conclusions and recommendations were formulated on the basis of the data obtained, the results were drawn up in accordance with the established requirements. Comparative analysis of data obtained from level and flow sensors showed a high correlation with control hydrometric measurements, which confirmed the correctness of the scaling and calibration algorithms. The operation of the PID controller ensured stable maintenance of the specified water level in the channel with a change in flow rate, with a minimum transition time and without significant overshooting.
