| Summary: | The article deals with the issues of providing
communication, as well as diagnostics and telemetry of
freight cars. The growth of rail traffic is currently placing
increased demands on the levels of safety, automation
and an increase in the average speed of freight trains.
These requests can be solved through the introduction
of modern GSM communication systems and geolocation.
At the present time, a system for detecting the descent
of a freight car has been developed and is being tested,
which makes it possible to record the descent within a few
seconds and transmit a signal to the train driver via a radio
channel. The systems for monitoring the location of wagons
and locomotives are no less important. However, one of
the current problems is the lack of autonomous power
supplies for communication and diagnostic systems. Since
wired power systems have a number of disadvantages, the
article discusses the creation of a power source based on
an alternator with permanent magnets. This generator is
driven by energy from a wheelset. The article presents the
results of a numerical experiment on the magnetic system
of axle-box generators using the ElCut software. |
