|
|
<p>The debugger window lets you look at information as it moves through the <a href=
|
|
"../../../../../../html/hardware/rps/index.shtml">RPS system</a>.</p>
|
|
|
|
<p>The upper left part displays the time value from each active receiver every time a reading
|
|
is taken.</p>
|
|
|
|
<p>If a position was successfully computed from a set of times, the "residual" value is
|
|
displayed for each receiver. This is the difference between the measured time and the time
|
|
that the RPS system expected to measure if the locomotive was really in that position.
|
|
Typical value are up to about plus or minus 100, corresponding to about a inch in accuracy.
|
|
If one or two receivers have much larger residual values, there may be a problem with the
|
|
readings from that receiver with the transmitter in its current location.</p>
|
|
|
|
<p>The bottom section of the window shows the position calculated from each reading. Below
|
|
the calculated positions is the return code from the calculation. A positive value is
|
|
considered OK, and a zero or negative value indicates some type of error.</p>
|
|
|
|
<p>It's also possible to type values into the fields and ask the system to process them as if
|
|
they were inputs. The selection box and button at the bottom are how you do this.</p>
|
|
|
|
<p>The "File" menu includes a "Start CSV Export..." item which can be used to copy the raw
|
|
input from the RPS system into a file. After you select this, you're presented with a file
|
|
dialog for selecting the output file name. If you select the name of a file that already
|
|
exists, it will be removed before output starts. Every RPS input after you select a file name
|
|
will be written to that file, and the menu choice will change to "Stop CSV Export...". Select
|
|
that menu choice to stop the logging and ensure that the last lines have been written
|
|
out.</p>
