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 scheam
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 is 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.
