%X Based on the requirement of industrialized efficient agriculture, a microcomputer measuring controlling system was developed The system consists of a master controller and some measuring controlling instruments, which located in greenhouse, and they are connected with RS 422A serial bus The instrument, which controlled by 89C52 single chip microcomputer, measures the environmental parameters of greenhouse, such as temperature, humidity, light intensity and CO 2 density The master controller realizes data communication, save, display, database operation and expert decision making The system is distinguished by its simple structure, high reliability, easy expansibility and good performance of anti interference
