Problems solved by technology

However, the existing cold chain food logistics has not yet formed a complete and independent cold chain system, and lacks logistics visualization technology during transportation, resulting in serious loss of food circulation links, affecting food quality and safety, and low logistics efficiency. Logistics companies cannot locate in real time. Real-time scheduling brings losses to food companies and third-party logistics companies

Embodiment Construction

[0023] refer to figure 1 , the method of the present invention comprises the following steps:

[0024] A. Obtain the attribute information of the food through the monitoring in the refrigerated compartment, and encode and compress the collected video stream to form a digital video stream;

[0025] (1) Logistics visualization of cold chain food includes monitoring and visualization of food temperature, humidity, status and order information in refrigerated compartments, data visualization of information identification and collection in food storage, storage and inventory links, and food transportation positioning path visualization. Divide the monitoring image f(x, y) in the refrigerated compartment into M×W sub-blocks, and perform discrete cosine transform on each image block S:

[0026] F=ASA T

[0027]

[0028] Wherein, i=0, 1, . . . , M-1, j=0, 1, . . . , W-1. After discrete cosine transform, the amount of low-frequency information in the image block is large, conce...

Abstract

The invention discloses a cold chain food logistics visualization method based on cloud video information processing. It mainly includes: A. Obtain the attribute information of food through the monitoring in the refrigerated compartment, encode and compress the collected video stream to form a digital video stream; B. map the video encoding to each shared channel, and optimize it through the time slot objective function Multicast transmission energy efficiency, transmit the surveillance video to the logistics center; C. Establish a dynamic tracking model of cold chain food logistics, obtain the position of the radio frequency identification signal through particle filter optimization, obtain the food transmission path, and realize the logistics visualization of cold chain food. This method has good timeliness and flexibility, can quickly, accurately, efficiently and non-destructively obtain food quality and safety information, accurately locate food and vehicles, facilitate remote scheduling and management of logistics companies, and improve logistics transportation efficiency and food safety. Transport security.

Description

technical field [0001] The invention relates to a cold chain food logistics visualization method based on cloud video information processing, which belongs to the fields of food safety, food transmission and radio frequency identification. Background technique [0002] In recent years, my country's cold chain food market has developed rapidly, and the development prospect of cold chain food logistics has attracted widespread attention in the industry. However, the existing cold chain food logistics has not yet formed a complete and independent cold chain system, and lacks logistics visualization technology during transportation, resulting in serious loss in food circulation links, affecting food quality and safety, and low logistics efficiency. Logistics companies cannot locate in real time. Real-time scheduling brings losses to food companies and third-party logistics companies. Contents of the invention [0003] In order to solve the above problems, the purpose of the p...
