COMMERCE BUSINESS DAILY ISSUE OF APRIL 21,1995 PSA#1330NASA, Johnson Space Center, BI2, Houston, TX D -- DATA ACQUISITION SOFTWARE SYSTEM FOR STRUCTURAL STATIC LOADS TEST
ING TO BE USED ON AN EXISTING HEWLETT PACKARD VXI-BASED HARDWARE
SYSTEM. SOL 9BI236511P POC Contact:FRAN MAHAN, Tel:713-483-2338
Contracting Officer:RON JOHNSON, Tel:713-483-4164 The Structures Test
Laboratory of the NASA Lyndon B. Johnson Space Center intends to
purchase a Data Acquisition Software (DAS) package for Structure Static
Loads Testing. The system is required to acquire data from strain,
pressure, load, termperature, and deflection sensing transducers as a
minimum. This DAS package must be fully compatible with an existing
hardware system and meet the requirements that define the system. The
company and personnel proposing to supply the DAS must have
successfully completed a similar product in the past and must supply a
reference list of customers for these products. The company must be
able to provide a product that meets the requirements by June 1996. A
demonstration of existing software will be required. The requirements
in the forthcoming Statement of Work will address hardware
compatibility, software functionality, and performance requirements.
The existing hardware will be available to the software developer for
software developement and functional checkout. The DAS shall run in a
Unix operating system environment on an existing hardware system. The
512 channel hardware system consists of a Hewlett Packard (HP) ''C''
size VXI mainframe (E1401A) with eight 64 channel multiplexor cards
(E1413A), one 16 channel Form C switch card (E1364A), and a MXI data
bus (HP1482B); a HP 745i workstation with 64 megabyte (MB) of RAM, a
MXI data bus interface board, and a 500 MB resident and a one gigabyte
external hard disk; a HP 747i workstation with 128 MB of RAM and a 1
gigabyte hard disk; five HP 700/RX x-terminals with 12 MB of RAM
consisting of 2 MB base, 8 MB expansion, and 2 MB video. The system is
configured such that the HP 745i is connected to the VXI mainframe via
a MXI data bus. The HP 747i is connected to the HP 745i through a HP
ThinLAN connection and a serial port, the five HP 700/RX x-terminals
are connected to the HP 747i via a LAN connection, and a HP
RuggidWriter printer and two LaserJet printers are available for use
with the HP 747i and HP 745i CPUs. Available software is HP/UX version
9 for both CPUs HP SICL for VXI control, LAN 9000 and C/ANSI C work
package. The DAS shall perform the following functions: 1) receive all
test data from the VXI mainframe via a MXi data bus and store all test
data to a 1 gigabyte hard disk on the HP 745i; 2) perform all warning
and limit checking on the HP 745i; 3) transfer data to the HP 747i
workstation for data display during testing; 4) perform all pretest run
configuration data (RCD) file buildup functions and perform all pretest
calibration functions with the VXI mainframe; 5) display data received
from the HP 745i on up to 5 x-terminals during test; & 6) perform post
test report quality processing of test data plots in the form of plots
and tabular data. The 5 x-terminals will be served by the HP 747i and
are required to display any one of ten predifined data tables
displaying up to a minimum of 56 channels each and any one of ten
predefined data plots displaying up to 6 channels each. Data display
updates to all terminals shall occur within one second for all data
being displayed. The DAS will be required to obtain data from the VXI
at rates of 0.1, 1 and 10 samples per second for each data channel up
to the maximum of 512 channels. The DAS must perform error trapping to
prevent the system from crashing due to soft ware and human operator
errors. A one-year time period is anticipated for full completion of
the project from date of award. System performance is of major concern
as the DAS will be used to acquire flight certification data for NASA
space hardware components and systems. Therefore, the DAS shall be
programmed using a language that allows all source codes to be compiled
and linked prior to the system being used. No part of the DAS shall
have to be recompiled or interpreted for each new test or during test.
The source code must be readable, documented, and verifiable for
quality assurance purposes. This synopsis is released in conjunction
with the sources sought synopsis released Jan 17, 1995. It is the
intention of the Government to use the MIDRANGE Best Value Sought
Procurement (Evaluation criteria and price). Interested parties should
respond to the NASA JSC Industry Assistance Office within 15 days of
the date this synopsis appears in the CBD. Questions regarding this
solicitation may be directed to BI2/Fran Mahan 713-483-2338. (0109) Loren Data Corp. http://www.ld.com (SYN# 0015 19950420\D-0001.SOL)
