Problems solved by technology

[0006] The above technical solutions are all for unified control of the global scope inside the greenhouse. The data finally monitored by the terminal can only represent the overall environmental conditions in the greenhouse. According to the monitored data, the control system can not meet the needs of plants after adjustment. The needs of growth, more precisely, cannot precisely meet the needs of plant growth. This is because the temperature, humidity, illuminance and other environmental factors in each area of ​​the greenhouse are different, which requires the environmental factors inside the greenhouse. Partition control

Embodiment 1

[0037] An intelligent control system for a photovoltaic greenhouse, comprising installing a cooling curtain 2 on one side wall of a photovoltaic greenhouse 1, a number of water inlets 21 arranged above the cooling curtain 2, and a water storage pool 22 arranged outside the greenhouse on the side where the cooling curtain 2 is located And the circulating water pump 23; the water inlet 21 is connected with the reservoir 22 and the circulating water pump 23 through pipelines, so as to ensure the continuous circulation of the water flow of the wet curtain. A plurality of fans 24 are arranged and installed on both sides of the photovoltaic greenhouse 1. The fan 24 is installed at a position farther from the wall than the wet curtain 2, and can be converted from different angles. It also includes distributing and installing a number of sunshade curtains 3 above the photovoltaic greenhouse 1. The top of the sunshade curtain 3 is black, which absorbs sunlight and heat during the day, a...

Embodiment 2

[0039] Taking the application of the present invention in a photovoltaic greenhouse in Huasheng Green Energy Solar Farm in Jimo District, Qingdao City as an example, this embodiment is the same as Embodiment 1 except for the following features.

[0040]The temperature inversion phenomenon in the photovoltaic greenhouse has always been a major hazard to the growth of crops in the greenhouse. In winter and spring, sometimes the temperature inside the greenhouse is lower than that outside the greenhouse. This phenomenon is called "temperature inversion". ", often around midnight, the crops planted are very sensitive to this, and frost damage will occur if you don't pay attention. Therefore, apply the present invention, in the daytime, the sunshade curtain is raised, and the daytime illumination intensity is big, and when temperature is higher, sensor 6 transmits data to data converter 7, and data converter 7 transmits to data processor 5, and data processing The device 5 processe...

Abstract

The present invention aims to provide an intelligent system for zoning and precisely controlling temperature, humidity and light intensity in a photovoltaic greenhouse. The system comprises a wet curtain installed on one side wall in the photovoltaic greenhouse, water inlets are arranged above the wet curtain, and a water storage tank and a circulating water pump are arranged outside the greenhouse. A plurality of fans is arranged and installed on two side walls in the photovoltaic greenhouse. The system also includes several sunshades distributed and installed above the photovoltaic greenhouse. A large database is established for crop growth in the photovoltaic greenhouse. The database comprises optimal temperature, humidity, and light intensity data needed in the plant and crop growth, the data is transmitted to a data converter, a data processor and a central processor through sensors, the data is compared, thus, the data is transmitted to a controller to control the water flow of the wet curtain, the air volume of the fans and the lifting and lowering of the sunshades, and the intelligent control of environmental factors in the greenhouse is achieved. According to the system, the growth of crops in the greenhouse is facilitated, the three-dimensional production of agriculture is achieved, and the system is a high-tech modern agricultural ecological construction project withthe integration of low carbon, energy saving and environmental protection.

Description

technical field [0001] The invention relates to the field of photovoltaic greenhouse facilities, in particular to a system for intelligently controlling the temperature, humidity and light intensity in the photovoltaic greenhouse. Background technique [0002] The temperature, humidity and light conditions in the greenhouse are directly related to the growth and development of vegetables. Scientifically and rationally adjust the temperature, humidity and light conditions in the greenhouse to form a small environment in the greenhouse that is conducive to the growth and development of vegetables, which is an important environment for the early maturity, high quality and high efficiency of vegetables in the greenhouse. [0003] As a new form of photovoltaic utilization, photovoltaic greenhouses are still in a relatively incomplete stage of technology. Planting crops in photovoltaic greenhouses involves many growth factors. During the growth of crops, light, temperature, humid...
