Development of a program for
calculation of various parameters of electrical circuits
We live in an age when
technological progress has reached such a level that increasingly there is a
need to simplify the different stages of both production and training, perform
scientific research. Such requirements can be seen in many spheres of our
society. In particular when training in high schools on the subject «Electrical
engineering, electronics & circuitry».
The search for optimal
solutions when working with the computer allows you to quickly obtain
information on current results and make the necessary adjustments, to implement
a deliberate transition from one mode of solving the task to another, modify
the settings of an electrical circuit, the accuracy of the solution and more.
For software
development we carried out a systematic analysis (preliminary design), which
identified the need for it, its purpose and basic functional characteristic
properties. In the beginning of the study, singled out, to solve electrical
problems three categories of software:
• virtual laboratory
works and theoretical studies on the electronic textbooks, which can be used
both in lectures and during independent work;
• in practical sessions
in the form of tests, in the preparation of the online exam.
• perform electrical calculations employed
during practical work and during the course and diploma projects and research
work.
Next, estimated cost
and possible effectiveness of the use of these software products, we have made
a list of requirements that the user expects from the finished product. Here is
setting goals and objectives, for which implementation is being developed and
the project itself. In the phase of system analysis, we can distinguish two
directions: research and feasibility studies.
In this work it was
shown using the software Simulink when modeling the various technical
calculations of electrical devices. The advantage of this program is that it
can be used even without knowing a programming language, it is most adapted for
all users. One of the most popular universal package, which produces electrical
calculations is MathCad with the processing of the experimental data and
graphing in MS Excel. But experience has shown that there is scope for
extending the range of software applications in solving electrical problems.
In everyday life one
can observe various solutions to simplify different things. For example,
electronic computing device known as a calculator is intended to simplify
performing mathematical calculations. With its help it becomes possible to
accelerate the process of calculations, which in turn will allow you to move on
to more advanced stages. When solving electrotechnical problems range of
applications of information technologies is high enough. Our goal is to
facilitate mathematical calculations for students.
The aim of this work is
to simplify the process of performing mathematical calculations different
parameters of electric circuits, by creating software based on Delphi language.
Objectives of the study:
1. To determine the
purpose of the program;
2. The design of the
program;
3. The writing of
program code;
4.
Revision/improvement/addition.
The planned result.
Planned features of the program (in this section functions which will be
implemented in the program):
• select the number of
plots chain
• selection of elements
on each circuit
• selection of
connection elements on each circuit
• select known
parameters
• calculation of
unknown parameters
This section provides
ideas for program functions that can be implemented, but perhaps not.
• save results of
calculations in Word
• the «Learning» mode.
Possible options: a
step by step explanation of the program; a description of the various electric
circuit parameters and their relationship.
As electronics open new
possibilities of its use in various branches of engineering and science. This
included knowledge of the principles, characteristics and parameters of analog
and digital parts of the computer, the ability to classify the main instruments
in which an electric current flows. It is important to understand in modern integrated
systems, that is, to know their properties, characteristics.
If you solve test
papers on electronics and papers on circuit design, it is necessary to be able
to use a variety of electronic and electrical components devices and circuits,
it is also important to be able to estimate the parameters of electronic items,
taking into account their feature usage. To facilitate the solution of such
problems and developed our program.
