Data Acquisition and Controls of An Environmental Chamber
by Roy C. Fonseca and Matthew F. Rector Advisors: Drs. I. S. Ahn, K. McConnaughay, D. R. Schertz The development of computer controlled environment systems has had a
strong influence on today's society. Such products as house and car climate
controls are becoming more reliable and sophisticated. The environmental
chambers of the Bradley University Biology Department are the focus of
this project. These chambers facilitate the study of plant growth in various
controlled environments, providing the biologists with new techniques for
studying plant growth. At the same time electrical engineering students
gain applicable design experience in data acquisition and control systems.
The design of a centrally controlled computer-based system for multiple
environmental chambers required an integration of control, data acquisition,
serial communication, local network, and microprocessor systems. Remote
68HC11 microprocessors in each chamber sample sensors and carry out local
control, communicating with a central 486-based PC. The PC provides a graphical
interface for operators as well as a central location for data collection
and display.
