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 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. (0108)
