Agricultural product cold chain storage transport fine control modeling and optimizing method

Abstract

The invention provides an agricultural product cold chain storage transport fine control modeling and optimizing method. The modeling method is characterized in that data information such as temperature factor, humidity factor, and gas concentration factor of a cold storage chamber can be acquired in a preset time; according to the acquired data information such as the temperature factor, the humidity factor, and the gas concentration factor, the response curves of the temperature, the humidity, and the gas concentration can be acquired, the per unit curves converted according to the corresponding curves can be acquired; the cold chain control models corresponding to the factors can be acquired according to the response curves and the per unit response curves; the cold chain fine control coupling models can be acquired according to the cold chain control models corresponding to the factors; the data information such as the temperature factor, the humidity factor, and the gas concentration factor of the cold storage chamber can be acquired in a real-time manner; according to the data information such as the temperature factor, the humidity factor, and the gas concentration factor of the cold storage chamber, which can be acquired in a real-timed manner, the output control signals of the factors can be acquired by adopting the cold chain fine control coupling models to change the frequency conversion refrigerator rotating speed, the electric humidification water valve opening degree, and the electric air control valve opening degree.

Description

technical field [0001] The invention relates to the technical field of cold chain logistics, in particular to a fine control modeling and optimization method for cold chain storage and transportation of agricultural products. Background technique [0002] Fresh agricultural products have the biological characteristics of freshness, perishability and aging. The freshness of agricultural products determines the use value and economic value of agricultural products. It is a fresh commodity with great difficulty and risk in circulation. The cold chain logistics of fresh agricultural products is based on the perishable process of agricultural products, using artificial refrigeration technology as a means, and connecting with production and circulation. Cold chain logistics keep fresh agricultural products throughout the process to ensure the quality and safety of fresh agricultural products. [0003] At present, the cold chain logistics system of agricultural products in my coun...
