66--Data Acquisition System

NA This is a sources sought synopsis for a Data Acquisition System in support of the United States Army Yuma Proving Ground Electronics Branch. The minimum requirements are for 64 channels plus date, time stamp and computation/event marker channels, the desi red requirements are for 128 channels. The Data Sampling is simultaneous. The Fast data sampling rates/channel for Accelerometer and Strain Gage sensors 10k, 5k, 2.5k, 1.5k, 1k, 500,100,50 (selectable or variable Anti-Aliasing). The Slow Data Sampling r ate/ Channel for Pulse Counting/Frequency Cards = 1Hz, For isolated Temperatures =1 Hz and Msc isolated voltages (5vdc, 10vdc, 50 vdc) =1Hz. The Power In for Vehicle Power @9-32vdc and for AC Power @60cycle =120vac. The Sensor Interfaces Lemo connectors to be determined except for thermocouples. The Operating Capability is: a. Stand alone operation with vehicle power (power draw is critical), b. Provide complete menu driven system for setup and operation, c. On-board data storage with simultaneous output streaming of data via Ethernet and/or Firewire, d. On-board data storage, minimum (primary)=10 minutes continuous operation at highest sampling rate, 128ch. e. On-board data storage, desired (primary)=60 minutes continuous operation at highest sampling r ate, 128 ch, f. Software for external device real-time viewing of data or processed data at rates decreased from maximum sampling rate (Operating System TBD), g. 12-bit ADC minimum and 16-bit or more ADC desired, h. On-board data remote file start, stop, and restart, stop capability (independent of external software) with unique file naming/each start, i. Data output formats: ASCII, Mat Lab, DADisp, j. Data Time Stamp Capability (UTC, 0.1 ms resolution, no latency) synchronized to GPS time (internal rec eiver) and/or to external IRIG-B input, k. Up to 8 remote event markers. The Typical Operating Environment: a. Rated for operation from -10C to 85C or provide a cooling package to enable operation in 125F ambient air with direct solar radiation of 360 BT U/sq-ft/hour (power is critical), b. Shock: MIL-STD-810F, 20g half sine wave, 11ms duration. Also vehicles impacting 12-in high half-round bumps and 12inch deep potholes, c. Vibration: MIL-STD-810F per Table 514.5-1, Transportation 4 Restrained Cargo and Operational, Ground Vehicles, Annex A Figures 514.5C-1 thru 514.5C-4(wheeled vehicles, trailers, and tracked vehicles). Also vehicles over Belgium Block and various washboard courses, d. Sand and Dust: MIL-STD-810F, Rain: MIL-STD-810F. The Sensors: Accel erometers: variable capacitance (such as Endevco Mdl 7290A) or piezoresistive (such as Endevco Mdl 2262C), Strain gage: 1/4 bridge, 350 ohm, (requires bridge completion circuits)(requires 10 vdc be provided by unit), c. Provide power for sensors. The Sen sor/Channel configuration: a. Accelerometers: (requires 10 vdc and 12 vdc be provided by unit) (80 channels), b. Strain: (32 channels or 24 strain and 8 temperature), c. Pulse/frequency: 8 channels, d. Msc voltages: 8 channels (0.5 vdc, 0-10 vdc, 0-50 vdc) , The individual voltage range selectable for each channel. Other requirements: a. Software and hardware documentation, b. Four days on-site training on hardware, software and operation for up to 4 persons, c. One year software and hardware support (optio nal), d. Minimum systems requires 48 combined strain and accelerometer channels of various combinations.
