Study & Application of Distributed System Which Based on AT89C51

The application of distributed controlling system which used in the measurement of temperature and humidity is studied in this paper. Its emphasis is the methods of principle & application which centralized a kind of intelligent controller microcomputer AT89C51. The system here can realize many functions, such as temperature & humidity´s measurement, displaying and alarm; the regulating and controlling of temperature & humidity, data storage and transmitting automatically, and so on. All the work are finished by computer, such as the analysis of temperature and humidity, many kinds of curves and report forms´ displaying and printing, the changing procession of temperature and humidity´s storing.
