USING HUMAN-MACHINE INTERFACE IN AUTOMATION OF WATER MANAGEMENT FACILITIES

Аннотация

This research is devoted to the consideration of the reasons for using the human- machine interface in the automation of water management, the problems and advantages of its implementation. At the same time, thecorrect application of the human-machine interface for the effectiveuse ofwater management inthe conditions ofUzbekistanis envisaged.

Uzbekistan Republic geographical location and there is rivers from the number come came out without water from the farm productive use of the day current blues in line it stands. Scientists stating the next 10-20 years inside In Uzbekistan water shortage further high to indicators output For these reasons, water farm correct organization to make, from it effective use main to the goal around is going on. For this and this water facilities further effective to do and thrift increase for modern from technologies use, process complete or partially automation big importance has will be. The present of the day pump of stations only some partially automated in the state of. Modern technologies stay to us this problems to solve help This is developed countries in the example of our vision possible. Human car interface pump at the stations stay to us this problems to solve and human labor efficiency further to increase big help togive possible. Materials andmethods. What does implementing a Human-Machine Interface (HMI) at pumping stations give us or what arethe challenges inimplementing it? With the help of the Human-Machine Interface, manually operated electrical equipment can be controlled using a visual display. This allows you to easily control and monitor everything from smallswitches tolarge complex processes. In this case, you can completely monitor, control, and monitortheworking process through a single display window. This eliminates the need for many small switching devices and electrical equipment that pose a danger to humans. The Human- Machine Interface is able to perform several actions at the same time. It consists of a display that depicts the process in a graphical or schematic form, a keyboard for entering data, and buttons forcontrolling theprocess. Now let's look at the problems of supporting the human-machine interface. The very problem of automating the work of a human operator encourages developers of automation tools to transfer http://www.internationaljournal.co.in/index.php/jasass 521 Volume15Issue04, April2025 Impact factor: 2019: 4.679 2020: 5.015 2021: 5.436, 2022: 5.242, 2023: 6.995, 2024 7.75 as many functions as possible to technical systems. However, initially this desire was limited by two factors: 1) relatively weak computing resources and high labor intensity and cost of implementing automationsystems; 2) the lack of adequate models of complex systems and means of verifying them. It was believed that a person is not very reliable, but can act in situations where it is difficult to formalize it, while automation is the opposite. This rule formed the basis of the principle of distribution of functions, developed in the1950s by Paul Fitts. This principle determines theassignment of each function to the control entity that best performs this function. Based onthis principle, tables were created by various authors in the 1960s and 1970s, describing the qualities of a person and automationin terms of various criteria [2], forexample:  the level of complexity of the system, the level of uncertainty and the presence of formalized management models;  the level of noise, interference and signals containing useful information; – the reliability andrecovery rate of manand machine;  resource characteristics and features of human and machine operation, multitasking processes, overload capabilities, –performance and operating costs. Surprisingly, almost none of the works of that period seriously discussed such a criterion as the economic feasibility of automating a particular function. Over time, the situation with technical means anddesign toolschanged, significantly expanding thepossibilities ofautomation. Modern automated control systems for technological processes (TACS) can collect and deeply process large amounts of data, which allows transferring part of the control and management functions from a person to a machine. However, this leads to a decrease in the operator's involvement in the control process, which has a negative effect when a person is required to make complex and quick decisions. Being "loose", he takes time to assess the situation and prepare a decision. Therefore, an increasing number of modern works are focused on harmonizing the distribution of functions in order to constantly involve the operator in the control process. The problem of secondary activity and navigation HMI TJABT developers pay great attention to mnemonics, their dynamics, the design of windows for entering control effects, the selection and desi
