SECTION 2. Real-Time Data Collection (ADPSA)
This program collects data from an ADP in real time. The software must be run from DOS on a
PC-compatible computer with a minimum 33-MHz 386 processor, 640K RAM, VGA graphics,
and a hard disk. It provides a menu driven format to select ADP data collection parameters, real-
time display of the velocity data, and writes the ADP data to binary files on the computer hard
disk.
The program has two primary display screens: setup and data acquisition. The setup screen is for
selecting ADP operating parameters. The data acquisition screen provides a graphical display of
ADP data, as well as tabular information relating to data collection and recording. The
description of the real-time data collection software is divided into the following sections.
• Section 2.1 gives an overview of program operation.
• Section 2.2 shows command line options to modify program operation.
• Section 2.3 describes the ADPSA setup screen.
• Section 2.4 describes the ADPSA data acquisition screen.
• Section 2.5 discusses using ADPSA to integrate GPS position data with ADP velocity data.
• Section 2.6 describes the contents of ADP binary data files.
• Section 2.7 describes configuration and log files used with ADPSA.
2.1. Program Overview
When run with no command line options, ADPSA will first try to communicate with the ADP on
COM1 at 9600 baud (different communication parameters can be specified using command line
options; see section 2.2). If communication is established, it downloads the current hardware and
user parameters and enters the setup screen.
If communication cannot be established, ADPSA loads the hardware configuration file specified
in the ASCII text file ADPSENS.DEF. ADPSENS.DEF is a text file with one line naming the
hardware configuration file to be used. For example, if ADPSENS.DEF contains the following
line:
ADP4050.SEN
this specifies the configuration file ADP4050.SEN for serial number 4050. The hardware
configuration file allows the user to enter the setup screen without being connected to the ADP.
When using these files, the program outputs a message that communications were not established
and then enters the setup screen. The hardware configuration file and ADPSENS.DEF are
included on the software diskette.
In the setup screen, the user can modify operating parameters, view hardware configuration and
performance estimates, specify a recording file name, and start data collection. When data
collection is started, the program sends all user settings to the ADP, enters the data acquisition
screen, and begins collecting data. Within the data acquisition screen, the user can modify the
graphical display without affecting data collection or recording.
IMPORTANT: At the start of data collection, the ADP internal clock is set to match the
computer clock. This time standard is applied on all recorded data.
