Distributed Data Analysis in a Mobile Real Time and Minicomputer Network Environment

摘要

The system design and analysis processes involved in collecting data from a mobile laboratory to a finished analysis are presented. This involves real-time data collection on a small mobile cart, an intermediate analysis station in a nearby mobile van, and the final analysis performed through a minicomputer network of facilities. An iterative approach to data collection and review was established to provide timely analysis and verification of incoming data. This requires a highly interactive user-oriented environment in the field. After the data have been collected and preliminary analysis has been completed, the results can be integrated into a larger analysis system through a minicomputer network. This procedure also allows for utilization of high-cost equipment that cannot be placed in the field. A single hardware interface, BATNET (Battelle Network), is used to perform all data transfers via either radio (cart-to-van) or external network connections (van-to-computer network). The key software components described are a self-describing data base system utilizing simple relational data base concepts, a simple command language allowing analysis and investigation in the field, and a simple preview system for intensity-modulated data. 2 figures.
