Development of rail Profiler
Rail wear is a major cause of railway
accidents. Wear imposes speed restrictions and also increases
operating costs due to higher energy consumption. Wear needs
to be monitored continuously and worn tracks need to be
replaced. Hence the need for a device for recording the
rail-profile.
We offer technology for a portable unit
that can be carried manually. An electro-mechanical on-field
recording unit can be interfaced with any PC. A two jointed
mechanical system designed acting as a miniature co-ordinate
measuring machine is incorporated. The schematic is shown
here
The on-field device is electronically
controlled and is equipped with a single chip EEPROM, flash
program memory, a keypad and RAM. The field recorder will have
onboard memory that can be transferred on to solid state
memory cards, and can later be downloaded to a PC. There will
be no requirement for an on-field computer with this system.
In addition a software to compare the
measured profile with standard profiles is available. The
software can be used to directly plot the deviation from
standard profiles (wear).
Once the field units are installed, in a
second phase a software will be installed to collect and
monitor the data centrally using wireless links. This will
enable network wide monitoring of the track status through WAN
connectivity.
The final product might look something
like this.
