Intelligent control system and control method for greenhouse

Abstract

The invention relates to an intelligent control system for a greenhouse. The system comprises the greenhouse, a drip irrigation mechanism, a heating mechanism, a light supplementing mechanism, an automatic ventilation mechanism, a roller shutter mechanism, solar photovoltaic panels, a wind power generation device and a control cabinet and is characterized in that the drip irrigation mechanism is composed of drip irrigation pipes and water pumps; the heating mechanism is composed of heat supply pipes and a hot air generation device; the light supplementing mechanism is composed of multiple light supplementing lamps; the automatic ventilation mechanism is composed of two ventilation fans; the roller shutter mechanism is arranged on a sun-facing surface of the greenhouse; a control circuit iscomposed of a micro-controller, a temperature and humidity sensor, a PH valve sensor, an illumination sensor, a CO2 concentration sensor and a soil humidity sensor. The intelligent control system forthe greenhouse performs drip irrigation, ventilation, light supplementation, and hot ventilation operation when water content of soil, CO2 concentration, illumination and temperature are excessivelylow. Therefore, automated control over growth of crops in the greenhouse is realized. A better environment is created for growth of crops in the greenhouse. The intelligent control system for the greenhouse has evident beneficial effects and is suitable for application.

Description

technical field [0001] The present invention relates to a greenhouse intelligent control system and control method, more specifically, to a greenhouse intelligent control system and control method that can automatically perform drip irrigation, light supplement, ventilation and heating according to detected environmental parameters. Background technique [0002] China is a large agricultural country in the world. Since the 21st century, China's economy has developed rapidly, but the level of agricultural intelligence is still low. It is easy to cause environmental pollution during production operations, which is not easy to manage and wastes a lot of time and labor. Solving environmental pollution, difficult management, and labor force in traditional agricultural production has become one of the first problems faced by the development of modern agriculture. [0003] The intelligent control system has great convenience and advantages in agriculture, especially for greenhouses...
