“…1). At the same time, the attracted funds must meet metrological requirements and fulfill the requirements of aggregation, unification and typification [15,16,17], taking into account the prospect of increasing the equipment of the on-farm irrigation network with new means of accounting and automation of water distribution, information and communication technologies (such as AMR) [18], to create real conditions for the formation of the APCS on the VOS and its integrated movement in the ACS of the inter-farm part of the irrigation system [19][20].…”

The paper considers innovative solutions for irrigation in the areas of the on-farm irrigation network, carried out through the territorial division of a network of permanent irrigation canals into separate irrigated areas from each other. Some basic aspects of automation of the on-farm irrigation network are discussed, with relevant questions - what should be the accounting of irrigation water, and how should be carried out water intake and distribution aimed at water aimed at goals and objectives for their use on the irrigation network for drip and rain irrigation. They stem from the need to introduce automated means of automated systems and IT technologies on rural irrigation facilities for the near and far prospects in the context of global and regional climate change, reducing own and incoming water volumes. The work characterizes the economic and social effects of the work carried out. From this point of view, the work is characterized by analyzes the relationship of the farmer with the association of water users, based on instrumental monitoring and digital documented reports for the water consumed.

“…DPRM-V registers and converts into a code the time parameters of the AE signal, for example, the time of the beginning of the mode, the time of the end of the mode, the arrival time difference (RTD) modes for different sensors. A mode is a part of the AE electrical signal envelope at the output of the receiving transducer, located between two adjacent minimum values and having one maximum in this interval [20]. DPRM-D pre-amplifies, limits and converts the AE electrical signal into digital form.…”

“…It should also be noted that solving the problem of restoring the original AE signal shape allows us to reduce the further problem of fracture prediction to the problem of mechanics with its powerful physical and mathematical apparatus, apply existing computational mathematics tools and ensure the creation of the required control and prediction algorithms [14,15,16]. The study of acoustic signals emitted by areas of plastic deformation or zones of cracking of solids under mechanical loading and the use of AE signals for monitoring the state and predicting the strength of mechanical engineering objects form the conceptual basis of the AE method [17,18,[19][20][21][22][23][24][25].…”

Research on the problems of creating effective control and diagnostic systems allows us to single out the following areas: development of the theory and methods for diagnosing and predicting the strength and reliability of structures, theoretical and experimental studies of fracture processes and the corresponding changes in characteristics and parameters, i.e. carriers of information about the processes occurring in the material during destruction; creation of information-measuring systems designed to register and analyze the information necessary to resolve the issue of the state of the structure; development of software for measuring equipment, including not only the main programs for generating and processing incoming information, but auxiliary subroutines that provide information compression, increase the reliability of measurement results, defect recognition, decision making. The article is devoted to the methods of acoustic-emission control of metal structures and the development of a computerized system for its implementation. The basics of organizing a software-algorithmic system for locating and processing acoustic emission signals are considered, including: methods for discretizing models of sensors and acoustic emission signals, which make it possible to obtain computational schemes such as a digital filter that provide effective algorithmic implementation; description of fragments of an experimental software-algorithmic system for processing acoustic emission signals, illustrating the principle of constructing software tools in an arbitrarily chosen computing area, the structure of the software organization of computational processes for locating an acoustic emission signal, which ensure the construction of the corresponding subsystem of a computer complex for acoustic-emission control, both in single-antenna and in a multi-antenna version.

With detailed large-scale topographic surveys of cities, especially when photographing executive master plans of industrial facilities, geodetic services perform work on measuring not only ground sites, but also - on detecting and localizing of underground utilities: water, oil and gas metal pipelines, power and telephone cables, etc. The search for underground communications by various services is carried out at use of special electronic devices for searching of underground communications: tracers, cable detectors. A number of shortcomings have been identified when operating these devices, including difficulties in detecting and fixing of pipes or cables in conditions of increased industrial interference, insufficient efficacy and accuracy of the search process, high energy consumption, low level of ease of operation, due to relatively large weight and size parameters. A comparative analysis of currently used search devices has proven technical defects of circuit solutions, and has formed the basis for developing of an electronic circuit. A working model of an underground utility finder with a pulse converter has been produced. Main technical characteristics were obtained after testing. The technical solution has been patented in the GU of the Intellectual Property Center of the Republic of Uzbekistan.
