Automation of productions is a necessary condition of reduction of losses for processing enterprises. Any automated system contains subsystems, each of which solves specific objectives, being at the same time accessory of all system. Therefore, when starting designing a system of acceptance and processing of raw materials, it is necessary to define the importance of result of the solution of each task for increase in efficiency of a production cycle. In the article we present results of expert polls of experts – wine makers for definition of problems of automation of processes in the plants of primary winemaking
We have designed and offered a voltage quality
analyzer that allows you defining relative deviation of
voltage, voltage unbalance factors at zero and negative
sequence. The device differs from the existing ones
with simple design and circuit solutions; it has low
price and the ability to conduct a continuous
monitoring of quality indicators of electric energy
The level of technical development today requires the creation of highly effective, including reliable, uninter-rupted power supply systems. We have shown modern requirements and design features of modern systems of uninterruptible power supply, which should be built on a modular principle. It is shown that the problem of synthesis of systems in a modular approach is addressing three issues: development of the structure of the system subject to the requirements of consumers to quality of power and the allowable time of power outage; determining the required level redundancy of major functional units (blocks, elements) to ensure the required reliability of the system; - ensuring the most effective interconnection of modules, including electromagnetic compatibility, and the rational use during normal and emergency operation of the system. We have proposed new structural solution of the main functional units and uninterrupted power supply systems in modular design. To reduce EMI and improve efficiency uninterruptible power supply systems in the design of static converters we need to use a transformer with a rotating magnetic field. In addition, the prospective current is to be used as a source of renewable energy. Another promising approach is the use of direct frequency converters as voltage stabilizers and frequency of the current
Promising is the direction and, above all, in matters of energy saving and energy efficiency of Autonomous systems of power supply, the use of renewable sources-newable energy as a major source of energy for consumers in remote areas. Here priority is given to solar energy. Since solar radiation can be change place not only in heat and electrical. The article contains three main structural schematics of electricity supply with solar power plants. The features of their work are disclosed, as well as an algorithm for calculating solar energy systems, the sequence of which is to define the required parameters, the daily energy consumption by consumers of electric power, the calculation capacity of the battery, the choice of the inverter and determining the area of solar batteries. The article reveals the conditions that affect the calculation of the PV system. It is shown that the greatest efficiency, including economic and reliability we have at combined (hybrid) Autonomous system, which was carried out with both solar power and wind power and gas stations. The important matters of improving the reliability of solar systems are the introduction to the design of a new element of the base, and first and foremost, Autonomous inventors performed on a single-phase transformer with a rotating magnetic field
Intuitively everyone understands that noise is a signal
in which there no information is, or which in practice
fails to reveal the information. More precisely, it is
clear that a certain sequence of elements (the number)
the more is the noise, the less information is contained
in the values of some elements on the values of others.
It is even stranger, that noone has suggested the way,
but even the idea of measuring the amount of information
in some fragments of signal of other fragments
and its use as a criterion for assessing the degree of
closeness of the signal to the noise. The authors propose
the asymptotic information criterion of the quality
of noise, and the method, technology and methodology
of its application in practice. As a method of application
of the asymptotic information criterion of noise
quality, we offer, in practice, the automated systemcognitive
analysis (ASC-analysis), and as a technology
and software tools of ASC-analysis we offer the universal
cognitive analytical system called "Eidos". As a
method, we propose a technique of creating applications
in the system, as well as their use for solving
problems of identification, prediction, decision making
and research the subject area by examining its model.
We present an illustrative numerical example showing
the ideas presented and demonstrating the efficiency of
the proposed asymptotic information criterion of the
quality of the noise, and the method, technology and
methodology of its application in practice
Stable obtaining in high quality fruits in the required
volumes for Russia is possible in the transfer of
industrial gardening to intensive cultivation system.
Planting of this type provide a high early appearance
and productivity, high quality fruits and quick payback
on investment in their creation means. All of this is
formed in the nursery garden. Under these conditions,
the development and introduction of innovative
machine technologies for industrial production of
sticks is an urgent task. The problem of mechanization
of the technological operation for earthing up ratoon
shoots of vegetative propagated stocks has been
considered in this work. A perspective scheme of
machine comprising two milling rotors which have a
flanked line with axis of rotation parallel line plants
proposed consequently analytic research constructions
of technical means for earthing up ratoon shoots. The
program of the research for parametrics milling barrel
for earthing up ratoon of vegetative propagated apple
stocks include defining the dependence impact of the
kinematics indicators (forward and circumferential
speed of labor body) and the constructive indicators
(quantity of blade and angle of their setting) to
qualitative criterion: structure of soil provide optimal
establishment stocks, and form of swath. Attainment of
agrotechnical demands for earthing up ratoon shoots of
vegetative propagated stocks is provided by the given
aggregate under circumferential speed of labor body
υ=3,9 m/c, quantity of blades – 4 pieces and angle of
setting blades on rotor γ = 10°
…20°
. The use of a
universal complex for the work in queen cell with
technological module for earthing up ratoon shoots
will allow not only labor-saving, but also mark up
leaving of qualitative ratoon
