The invention discloses a greenhouse vapor pressure difference automatic regulating system and method. The system comprises a temperature and humidity sensor, a single-chip microcomputer controller, a solenoid valve, spraying pipes and spraying heads. The temperature and humidity sensor is used for collecting temperature and humidity data in a greenhouse in real time. The single-chip microcomputer controller is connected with the temperature and humidity sensor through a data line and used for calculating vapor pressure difference numerical values in real time according to temperature and humidity numerical values and giving out a control signal. The solenoid valve is connected with the single-chip microcomputer controller through a data line and used for receiving the signal of the single-chip microcomputer controller to control a water source to be switched on or switched off. The spraying pipes are used for conveying water. The spraying heads are connected with the solenoid valve through the spraying pipes and used for spraying water to regulate the vapor pressure difference in the greenhouse. The greenhouse vapor pressure difference automatic regulating system and method are high in measuring precision and accurate in calculation base, and reliable technical support can be provided for environment regulation, disease prevention and water stress of the greenhouse.
Description
technical field [0001] The invention belongs to the technical field of greenhouse environment monitoring and management, and in particular relates to an automatic adjustment system and method for water pressure difference in a greenhouse. Background technique [0002] Greenhouse water pressure difference is one of the important parameters of greenhouse environmental management, and its value directly affects the growth and development of crops. [0003] At present, the water pressure difference in the greenhouse mainly relies on manual management, and water is sprayed according to experience, which is time-consuming and laborious and is likely to cause inaccurate adjustments. Contents of the invention [0004] The object of the present invention is to provide a system and method for automatically adjusting the water pressure difference in a greenhouse, aiming at solving the problem that the water pressure difference in a greenhouse mainly relies on manual management, which...
