Research and Application of Auto-control System for Solar Greenhouse Comprehensive Environment With Temperature as Principal Parameter

Aiming at solving problem existing in the comprehensive environmental control of Chinese energy-saving solar greenhouse, an auto-control system was established where the temperature was taken as a principal parameter. Dynamic programming and research results show that the temperature is the principal factor in the comprehensive environment of solar greenhouse. Furthermore, this system solves the problem economically and efficiently. It is possible to realize the dynamic equilibrium control of composite environment with the single chip microcomputer 8031 as micro CPU. And favorable socioeconomic benefit can be obtained.
