黑龍江工程學(xué)院本科生畢業(yè)設(shè)計ⅡABSTRACTThe level of auto-control water-saving irrigation technology reflects the development condition of agriculture modernization.The low automatic level of irrigation system is the main reason that prevented our agriculture’s development.As to this condition,this paper mainly studies the water-saving irrigation system that controlled by MCU.This system can supervise humidity.it can irrigate to the demand of the farm crops with right amunt of water at well time.The control part that consists of MCU is its core.Research work had been carried on irrigation control technology,hardware and software program and so .The control that consists of MCU is its core.A set of automatic water-saving system which is controlled by sing-chip controller have been developed in this paper.The overall structure of system、the main circuit of the MCU system、data-collecting circuit、I/O expanding circuit are all the designed.For monitoring large-scale irrigation system,we use distributional control model to enhance stability of the system de reduce the cost.It is small,easy to fit,a strong capability to resist interfere and low-cost.So the control system is more economic compared to other control system such as thuter system and all these demonstrate this production is adept to be popularized.This work is a fresh attempt to bring our agriculture into an advanced stage,which now is relative to be backward greenhouse control technique,especially on the aspect of nutrient liquid supplying when crops cultivated on tissue.Key words: AT89C51 MCU; Humidity Sensor; A/D transform; Sampling; Chip
