A cold chain logistics system for fresh agricultural products with traceability

Abstract

This application belongs to the technical field of cold chain logistics distribution, and specifically relates to a cold chain logistics system for fresh agricultural products with a traceability function. The lower end of the refrigerator box is provided with a guide rail, and the upper center of the refrigerator box is provided with a cold air joint. There is a block device on the top, and a carton storage car is installed in the refrigerating room. The rollers at the lower end of the carton storage car roll along the guide rail. For the cartons of fresh agricultural products, temperature and humidity sensors are installed near the cartons. The data acquisition system collects the temperature and humidity data of the temperature and humidity sensors in real time. Through the cooperation of carton storage vehicles and refrigerated vehicles, the air conditioner can effectively refrigerate the fresh agricultural products in the cartons, and use traceability The system determines the collection of traceability information of fresh agricultural products in the process of collection, transportation, sales, etc., to ensure the safety of the quality of agricultural products and consumers' full awareness of agricultural products when purchasing.

Description

technical field [0001] The application belongs to the technical field of cold chain logistics distribution, and specifically relates to a cold chain logistics system for fresh agricultural products with a traceability function. Background technique [0002] The statements in this section merely provide background technical information relevant to this application and do not necessarily constitute prior art. [0003] The existing agricultural products are divided into sales in the same place and sales in different places. First of all, the characteristics of sales in the same place are that the types are relatively single, but the agricultural products are relatively fresh, while the characteristics of sales in different places are that the logistics transportation is more troublesome, but the variety is diverse. If it is unqualified, it will cause the agricultural products to be stale. Secondly, the retrospective investigation of sales in different places is more difficult t...

Problems solved by technology

[0005] 1. It is difficult to trace back

[0006] 2. The packaging of agricultural products is mostly packed in cartons, but the cartons have poor compressive capacity, and the cartons are easily damaged in refrigerated vehicles

[0008] 4. Most of the cartons in the refrigerated car are stacked layer by layer, which can easily cause the cartons to be crushed in the refrigerated car. At the same time, when the cartons are stacked, the cold air flow is not easy to flow through the gaps between the cartons, resulting in poor refrigeration effect. Difference
