Abstract
A system for collecting and analyzing data from widely spaced air monitors was described. The system contained a series of air monitors designed to monitor particulate matter and hydrogen-sulfide (7783064) continuously in the workplace. The monitors themselves had no internal data storage capability and under normal use provided only local alarms for a preset particulate and hydrogen- sulfide concentration. The monitors were connected to two remote microcomputers through data acquisition modules that were connected into a subnetwork. The remote microcomputers were connected to a central computer by means of a local area network (LAN) that utilized twisted pair cabling and operated at 1 megabyte per second. The main computer could acquire, store, and display data from the air monitors. Interaction of the user with the data was provided through a uniform format that used three areas for data presentation: an information area that displayed data and accepted data input, a navigation area that provided prompts or menu selectable options to gain access to all system functions, and a message area that displayed warnings, help messages, errors, or other messages not related to on/screen data. The authors conclude that data from air monitors located throughout a factory can be collected on a factory wide basis if a factory wide LAN is available. The LAN could provide information that would be valuable for industrial hygienists.
