An Internet of Things-based fresh product perception instrument and a method for monitoring the cold storage supply chain

Abstract

The invention discloses a fresh food sensor based on the Internet of things and a cold insulation supply chain monitoring method. The method is used for monitoring the whole process of logistics of fresh food to avoid chain scission. The monitoring method comprises the steps that the fresh food sensor is started to read the RFID label data of a monitored object for RFID identification and is bound with the monitored object, and a module number corresponding to the RFID label is set to enable the monitored object, the fresh food sensor and a monitoring center to be driven synchronously in an integrated mode; cold chain data are acquired; primary processing is conducted on the cold chain data; environmental data are compared with a temperature and humidity monitoring alarm critical value, and if the environment data are within the range of the set temperature and humidity monitoring alarm critical value, the shelf life and quality of the monitored object are calculated through an on-site data processor; obtained data are transmitted to a fresh food database of the monitoring center; data analysis and processing are conducted by a supply chain background server; network publicity is conducted; dispatching is conducted. According to the fresh food sensor based on the Internet of things and the cold insulation supply chain monitoring method, whole-course fresh food sensing, tracking and monitoring are achieved, and seamless linkage between the cold chain and the supply chain is realized.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to an Internet of Things-based sensor for fresh products, a cold storage supply chain monitoring system composed of the sensor, and a method for monitoring the cold storage supply chain using the sensor. Background technique [0002] The spoilage rate of fresh products such as fruits and vegetables in China is 25%-30%, and the loss caused is more than 100 billion yuan per year. These fresh products rot and deteriorate from the place of origin to the dining table due to improper storage temperature, humidity and management methods, which affects their safety. Sometimes the fresh products from the place of origin cannot be found by consumers, and consumers cannot find the fresh products they need. . [0003] The monitoring operation of the existing cold chain storage and transportation equipment and facilities is only fixed in the local static state. Part of t...

AI Technical Summary

Problems solved by technology

Part of the temperature and humidity monitoring of cold chain storage and transportation equipment and facilities only collects temperature and humidity information at a single point. The phenomenon of broken chains is serious and cannot accurately reflect the overall environment. Moreover, the monitoring function is single and out of touch with sales and consumption that require such information.
