Data acquisition module

The MARS software is adapted and compiled specifically for a given application. The software is organized into modules which can be interchanged as needed for a particular implementation. Most modules comprise a core of management, analysis, reporting, and plotting functions which are used for every implementation. For each application, a data acquisition module is adapted to suit the appropriate instrumentation. In addition, specialized analysis programming is added if required. The acquisition module, the core modules, and the specialized analysis modules, if any, are then linked into a customized application specific version of MARS. 

Process automation implies the real time acquisition and control of process variables such as temperature, agitation, material delivery, or quality control measurements. As far as the MARS system is concerned, a real time process is just like any instrument. The acquisition module merely requires more interactive monitoring, alarms, and control. This can be accomplished by means of a real time multi-tasking data acquisition module.

I.The first option consists of Tyree detectors (see option two below) integrated directly into a commercially available data acquisition system made by Eberline Corp. of Santa Fe, New Mexico. This option operates in a digital mode by detecting individual neutrons, transmitting pulses over a twisted shielded pair to the Eberiine data acquisition module (DAM), which then interfaces with the central control terminal ((2T-1). The CT-1 contains two microprocessors. The DAM and (2T-1 units cany out the data... 

A data amplification and signal conditioning module consisting of instrumentation amplifiers and the data acquisition module (Keithley KUSB 3100) were connected to the two sensors, in Wheatstone bridge configuration. This setup is capable of accurately measuring small resistance changes. 

Computer-controlled communication device with at least one digital output (DO) port enabled to send a TTL signal to trigger MS data acquisition (Model USB-1208LS USB-based data acquisition module. Measurement Computing Corp., Norton, MA, USA). 

The main computer carries out data analysis aiu long-term bulk data storage by using a sofiware pack age such as those discussed in ihe next section. The op erator controls the overall process through interactions with the main computer. Using data-acquisition modules such as these, v irtually any instrument or experiment can he interfaced with a computer for efficient analysis and oulpiii of inslrumental data. 

At the end of the infield inspection, the Data Acquisition Module exports all data in the form of text files that can be read and processed by the Data Analysis Module. 

Signals from the preamp boards on the chamber are fed into postamplifier modules located near (but not on) the chamber. I he output signals from the postamps are routed to the data acquisition modules in the counting house . Calibration signals can be applied under computer control to the preamplifier boards. 

There are four distinct modules to consider in most optical emission spectrometer systems the excitation module, the sample module, the emission module, and the instrument control/data acquisition module. The elements comprising each module (and variations therein) are captured in Fig. 2.7 and described in greater detail in the ensuing section.
