Intelligent greenhouse monitoring and control system and method

Abstract

The invention discloses an intelligent greenhouse monitoring and control system and method. The intelligent greenhouse monitoring and control system comprises a main controller and a background monitoring center. The intelligent greenhouse monitoring and control system adopts a sensor technology to carry out automatic control on the soil and air environment in the greenhouse through the backgroundmonitoring center, and automatically controls a drip irrigation system, a soil loosening and liquid injection device and a fan to carry out soil loosening, nutrient solution or clear water injectionand greenhouse ventilation through the main controller, thereby greatly improving the accuracy in the cultivation process of saffron crocus or stigma croci planted in the greenhouse. The soil loosening and liquid injection device is formed by the combined structural setting of a first driving mechanism, a second driving mechanism, a third driving mechanism, a lifting mechanism and a soil looseningand liquid injection rod, thereby not only greatly improving the accuracy and positioning function of the soil loosening and liquid injection device in the working process, but also greatly improvingthe overall working stability and reliability of the system. The system is reasonable in design, has high control accuracy and high use values, and is suitable for popularization and application.

Description

technical field [0001] The present invention relates to an intelligent greenhouse, in particular to an intelligent greenhouse monitoring and control system and its method, in particular to an intelligent system for automatic adjustment and control of the soil and the air environment in the shed during the process of cultivating saffron and saffron. Greenhouse monitoring and control system and method thereof. Background technique [0002] Saffron and saffron are endangered traditional Chinese medicinal materials. According to the "Compendium of Materia Medica", saffron and saffron have strong physiological activities. It has the functions of dispelling stasis and dissolving knots, reducing swelling and pain, cooling blood and detoxification, and can comprehensively improve human immunity. It is used for the prevention and treatment of cerebral thrombosis, vasculitis, anemia and physical weakness, postpartum congestion, neurasthenia, palpitations and mania and other diseases. ...

AI Technical Summary

Problems solved by technology

However, the sources of saffron and saffron are few, the output is extremely low, and the requirements for cultivation techniques are relatively high. Because only the stigma part can be used as Chinese medicinal materials, domestic saffron and saffron can only meet 20-30% of the domestic market demand. , Relying on a large amount of imports leads to extremely high prices of saffron and saffron. The sales price of processed saffron and saffron is as high as hundreds of yuan per gram, and the price of top-grade saffron and saffron even exceeds 400 yuan per gram.

At the same time, due to the low cultivation technology and poor cultivation conditions, fruiting cannot be achieved. Only relying on bulbs for asexual reproduction, the quality of bulbs deteriorates seriously during the propagation process, and the bulbs become smaller. The quality varies
