Overview: Computes
basic Time and Distance information from data retrieved from Electronic Data
Modules (cars and trucks) and formats it for enhanced examination by the Time
Distance Multiple Events module.
Entry into Module:
This module of the program is normally entered by clicking
on the REC-TEC block in the upper left of the REC-TEC Window
causing the drop-down menu to appear.
Place the cursor on the Time - Distance block and click on Time
– Distance (EDM) on the sub-menu to initiate this module.
Under certain circumstances, the user may choose to use the
Files block instead of the drop-down menu approach. Selecting any file with an .EDM
extension in the Dialog box accessed from either the Open Single File
or Open Multiple Files block opens this module.
Selecting AutoLoad [ON] from either the Setup
Menu or the AutoLoad Icon on the upper right side (third line) of
the REC-TEC Window automatically loads the scenario that was on the
screen when the module was closed, either individually, or when the program was
closed. With AutoLoad [OFF] on
the main REC-TEC Window, modules will start without loading a
file.
Data Entry:
This module is primarily used to evaluate data from Engine
and Airbag Control Modules. This module contains the following data entry
blocks within the leftmost frame:
·
Speed (Initial) – from ECM, CDR or Railroad data recorders
·
Speed (Final) – from ECM, CDR or Railroad data recorders
·
Event End Time – from ECM, CDR or Railroad data recorders
·
Start Phase (Controls Graphics and Data Table)
·
End Phase (Controls Graphics and Data Table)
Entry of variable information in the data boxes sufficient
to generate a solution and either clicking the ADD button to add another
phase, or clicking the green Arrow button causes output information to
appear in the Output for Phase frame and the graphics to update.
Output:
The right frame heading shows the Output for Phase
(number). The specific phase is
controlled by the yellow or green Arrow buttons and shows the following:
·
Time – Elapsed Time for the Phase
·
Distance – Distance traveled during the Phase
·
Speed (I) – Initial Phase Speed in Primary and Secondary
configurations
·
Speed (F) – Final Phase Speed in Primary and Secondary
configurations
·
Total Distance – Distance from Start Phase to End Phase
·
Total Time – Time from Start Phase to End Phase
Instantaneous / Average
·
g(A/D) – Acceleration/Deceleration factor for Phase
·
Rate: – Acceleration/Deceleration rate for (Start) Phase to (End) Phase
in Primary and Secondary configurations
Options:
Several Command Buttons appear in a frame located at
the lower left corner of the module Window.
The Command Buttons allow the user to engage options including
the option to Open and Save the data required to generate the
scenario shown on the screen at the time the file was saved.
·
Open .EDM File – Calls up a Dialog box, which Opens any
pre-existing .EDM file and displays the output results.
·
Save .EDM File – Calls up a Dialog box, which Saves data on
the screen to files with any user-selectable filenames. This is independent of the automatic saving
as “LastFile.EDM” of the data at the close of this module or the close
of the program.
·
Graphics (Re-draw) – Forces the program to re-draw the graphics
curves for Time (with scales) on the upper half and Distance (with scales) on
the lower half of the screen. The right
and left scales show the Speed.
·
N – This button toggles a graphical number pad on the screen
that can be used to enter data into the input boxes without using your keyboard
number pad. This may be useful for
presentations as data entry can be accomplished using a wired/wireless mouse.
·
Data Table – Displays the basic information from the Start Phase to the
End Phase in a table. A Check Box
will allow the user to effectively remove the Speed information for the
selected Phase(s) from the computations.
Compute:
Several Buttons, Input Boxes and a Command
Button appear in a frame located at the lower middle of the screen. Entering a value Time, Distance
or Speed and clicking the associated (round) button will display values
for the other two variables in the boxes and show the location on the curve of
the entered value. If Speed is entered,
the program will show the first instance of the speed.
The Command Button will transfer the current
information and program control from Time – Distance (EDM) to Time –
Distance Multiple Events for further evaluation and processing.
