Intelligent greenhouse control system and control method

Abstract

The invention relates to the field of greenhouses, in particular to an intelligent greenhouse control system and method. Comprising a greenhouse body and a communication device, a processor, a detection device and an irrigation device which are installed on the greenhouse body, the irrigation device comprises an accurate irrigation assembly which is arranged around a plant and used for accurately watering all parts of a plant root system, a conveying assembly used for conveying irrigation water for the accurate irrigation assembly, and a temperature control assembly used for adjusting the water temperature of the irrigation water; the precise irrigation assembly comprises a water storage part provided with a valve and a flow dividing part, the flow dividing part is inserted into soil around a plant root system, through holes are formed in the side face of the flow dividing part, and the flow dividing part is connected with the valve on the water storage part; the flow dividing parts comprise the first flow dividing part and the second flow dividing part, the first flow dividing part waters shallow soil, and the second flow dividing part supplies water to deep soil. According to the method, a more accurate irrigation mode is adopted, weather forecast and multiple parameters are jointly analyzed to accurately adjust the greenhouse, the control effect is optimized, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the field of greenhouses, in particular to an intelligent greenhouse control system and a control method. Background technique [0002] With the improvement of people's living standards, people's demand for agricultural and sideline products is also increasing, and due to the poor endowment of agricultural resources in my country, the planting area of ​​greenhouses needs to be expanded accordingly. However, most of the existing greenhouses use manual control to adjust various parameters in the greenhouse, and the degree of automation is not high enough. [0003] Prior art 1, Chinese invention patent, publication number CN210445075U, publication date 20200505, discloses an IoT-based agricultural intelligent greenhouse monitoring system for automatic monitoring and control of parameters in the greenhouse. [0004] However, there are still problems in the prior art 1. The monitoring system in the prior art 1 passively controls ac...

Problems solved by technology

[0004] However, there are still problems in the prior art 1. The monitoring system in the prior art 1 passively controls according to the changes of various parameters in the greenhouse. There is a problem of single control for the control of various parameters, and various parameters are not considered. The situation of mutual influence between them leads to delay in the control and inaccurate adjustment

Moreover, the irrigation method in the traditional greenhouse is too simple, which consumes a lot of electric energy and water resources, and is not energy-saving and environmentally friendly enough.

Since the various parameters in the greenhouse are affected by the outdoor weather at the same time, the control method in the prior art that does not consider the external weather is not effective

[0005] Therefore, an intelligent greenhouse control system and an intelligent greenhouse control method are needed to solve the problems of delay in the control system in the prior art, poor effect of single parameter mechanical adjustment, high energy consumption, and environmental protection.
