Research And Development Of Mushroom House Envirowment Parameters Control System

Edible mushroom is a special agriculture product, which has high requirement for climate and environment, and only can grow in certain conditions. Since the mushroom is planted in hand-made way, which is low efficiency, low output, poor quality and few kinds , its output and quality can not meet people's requirement of health and edibles. The research is focused on the technology to control edible mushroom's growth climate and environment for improving its output and quality. Agriculture scientists have been doing research on the control technology of single environment factor in greenhouse, including temperature, humidity, carbon dioxide and so on.A scheme of the control system based on MCS-51 computer is brought forward in this paper, which makes the temperature, humidity and carbon dioxide of the mushroom house adjusted automatically. The periphery circuit, which is made up of sensors, electric valves, transducer, LCD, MCU etc, is designed.Fuzzy control arithmetic is appied in the mushroom house climate control system, which is complex non linear system and modeled difficultly with general method. The expected goal is reached on the whole using fuzzy control arithmetic. The control system is designed to adjust mushroom environment parameters using automatic controlling technique.The research is a part of the subject of edible mushroom's cultivation in Dalian Biology Science and Technology Company. It is proved that this system can control the temperature and humidity of mushroom house, and meet the requirement of environment for edible mushroom through test. The design of intelligent mushroom house is significant for improving the standardization and industrialization of edible mushroom in China.
