Agricultural environment heat preservation quilt control system and method

Abstract

An agricultural environment heat preservation quilt control system comprises a detection module, a control module and an implementation module. The control module comprises a data analysis module and a compensation module. The data analysis module processes detection data of the detection module, conducts comparative analysis of the detection data and experience data, obtains a conclusion, and emits an instruction. The compensation module conducts compensation optimization on an analysis result of the data analysis module through comparative analysis of the detection data of the detection module and control parameters. The implementation module receives an instruction of the control module to roll or unroll a heat preservation quilt. The priority of data parameters in the data analysis module is as follows from high to low: external illumination, greenhouse earth temperature, greenhouse temperature, temperature differences inside and outside a greenhouse and external wind speed. Through accurate detection and analysis of environments inside and outside the greenhouse and also through continuous data analysis, the moment when the heat preservation quilt is rolled or unrolled keeps being optimized, and accurate control over insulation and lighting of the greenhouse is realized.

Description

technical field [0001] The invention relates to the technical field of agricultural environment control, in particular to an agricultural environment heat preservation controlled system and method. Background technique [0002] The solar greenhouse adopts relatively simple facilities and makes full use of solar energy. In cold regions, vegetables are generally cultivated overwintering without heating. The solar greenhouse, which is a cultivation facility for fresh vegetables, has distinctive Chinese characteristics. It is a facility unique to our country. The structure of solar greenhouses varies from place to place, and there are many classification methods. As the main body of my country's protected agriculture industry, the "solar greenhouse" industry has become the most profitable industry in agricultural planting in the past 20 years. It solves the long-term off-season supply of vegetables in winter in northern my country, increases farmers' income, saves energy, promo...

Problems solved by technology

The performance of solar greenhouses: the light transmittance of energy-saving solar greenhouses is generally above 60%~80%, and the temperature difference between indoor and outdoor can be kept above 21~25 degrees Celsius, but the current management of solar greenhouses has not been refined. Management. At present, greenhouses generally achieve the effect of heat preservation through heat preservation quilts, and realize the control of daylighting through heat preservation quilts. The control of the roll-up of heat-insulation quilts affects the growth of internal crops, and the control of the roll-out time and time of heat preservation quilts Depending on the internal environment of the greenhouse, for different types of crops and agricultural greenhouses in different locations, there is currently no perfect thermal insulation quilt rolling control system and method, which can provide the best for the growth of crops through the collection and analysis of environmental parameters inside and outside the greenhouse. The environment affects the development of domestic greenhouse planting
