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.
