One of the main part of locomotive
depot technical room is the training equipment for study a work
and principles of troubles shooting in locomotive electrical
circuits. This equipment usually consist of the real locomotive
working equipment up to whole highvoltage chamber. It allow to
observe the working oder of relayes and contactors, to input and
then find scheme damages and to check a knowledges of workers.
Although many advantages of such educational method it has some
shortcomings. They are bulky and dear, that is wy can't be
changed when the locomotive type or it scheme variant are
changed. As far, as locomotives become obsolete, the number of
their modernizations and scheme variants are increasing. So, the
using of this training equipment with effectiveness is realy
impossible.
At Locomotive
Department of Saint Petersburg State
University for Means of Communications have
been developed some soft products, which combine, in authors
opinion, the functionality of real training equipment with
visuality and flexibility of computer program. This training
program is containing a some scheme pages of a 
corresponding
locomotive, such as we may found in Locomotive Manual or other
technical literature. But, in defference from "dead"
static paper scheme, the scheme in training program is
"alive" (animated). The clicking on image of
knife-switch, button, breaker leads to switching corresponding
part with changing of its image colore and condition (if it was
breaked, now it will be coupled and the contrary). This leads to
voltage supply on scheme junctions and, may be, on relaies and
contactors coins. In this case their images color changes from
black to red and their contacts in the scheme different parts are
coupled or breaked, that caused the changes of other relaies or
contactors and so on. The the method of scheme mathematical
modelling, developed by authors, allow to reproduce a full work
of real scheme and don't restrict the order of control elements
turning and their combination. Do you forget to turn on anything,
or didn't you know, that this
must be turned on? The scheme will be at the same condition, that
a real scheme with the same condition of control elements. Is the
switching from one scheme condition to another too quick in real
time and you don't have time to study the order of equipment
work? Press the button "Trass"
on program control pfnel and switch in trass mode working. Do you
need to know the condition of prime mover and some other
locomotive equipment? Press the button "Instruments"
and see the instrument panel with some instruments, which
measures the different parameters of prime mover, electrical
transmission and auxillery equipment. Do you want to see, what
would happen, if this or that defence apparatus would work?
Couple the contact of according apparatus (by clicking on it
image) and observe the scheme work. At last, the working of good
condition scheme is clear, but it would be interesting to know,
what will happen, if this...or that...or this and that electrical
contacts will damage at the same time? Press the "Damages"
button and switch in the set damages mode work, in which any
contact may be countiniously coupled (which is the imitation of
contact "welding') or continiously breaked (which is the
imitation of "burnt"
contact ). Then return in normal mode and observe the damaged
scheme working. Do you want try to find damage, which was set in
one of 40 variants? You may use a control lamp for this. Press
the button with lamp image to get it. Connect one of its
"crocodiles" to minus junction (by clicking on image of
junction) and use other "crocodile" to check a plus
junction condition. If this junction is under voltage, the lamp
is lighting. You is a boss or a teacher and want to check the
knowledges of your workers or students? By using a special
program you may form four variants lists (up to 40 families in
each of them), setting one of the 40 variants to each worker
(student). He has 15 minutes to execute his variant and then the
results of execution will be noticed in a special file, which may
be read by the same program. All programs satisfactorily works on
IBM-compatible computers in following minimal configuration:
During some years this programs are sucsessfully used:
In the table you may see the screenshorts and download
the demo version of training program "The scheme of 2M62 diesel
locomotive control circuits". It is a Russian locomotive,
which works now on Russian railways and during some years was
exported to some countries of Europe and to Mongolia. Some
featurs of full version are absent in demo version (specifically,
the working with damages variants, with control lamp, setiing
damages mode are impossible). During installation process program
don't write anything to Windows Registry or System folders, that
is why it can't damage your system. If you will launch program by
the aid of shortcut, which is creared on Desk Top by installator,
please, don't forget to write program folder path in the
shortcut's "Program folder" property.
The authors are interesting in your comments and suggestions
about the program. If you have them write us.
