Embodiment Construction

[0035] combined with Figure 1-7 , further describe the technical solution of the present invention:

[0036] 1. Overall functional design

[0037] The present invention realizes the communication between the monitoring center computer and the detection nodes and aggregation nodes of the food storage environment, transportation environment and fresh-keeping environment through low power consumption, long-distance LoRa wireless network and GPRS network, and applies LoRa communication technology to long-distance wireless food safety In monitoring, the detection of food safety information is realized. LoRa long-distance communication greatly reduces the use of relays, saves costs, and realizes the detection and centralized management of food safety. The food environment parameter collection platform includes a management center computer, 3 groups of multiple detection nodes, 3 convergence nodes and a GPRS network. The 3 groups of multiple detection nodes form 3 environmental par...

Abstract

The invention discloses a food safety detection system, which is composed of a food environment parameter acquisition platform and a food freshness big data processing subsystem.According to the influence of the storage, transportation and fresh-keeping environment factor parameters of the food and the fresh-keeping time on the freshness of the food, environmental factor parameters and time of the food in different links are collected to identify the freshness of the food, and beneficial reference is provided for environmental factor adjustment and corresponding time determination of food storage, transportation and fresh keeping; the food safety detection system effectively solves the problem that the food quality is greatly influenced due to the nonlinearity and large lag of food processing and transportation environment temperature parameter change in different circulation stages in the prior art.

Description

technical field [0001] The invention relates to the technical field of food safety detection and processing, in particular to a food safety detection system. Background technique [0002] With the improvement of people's living standards and the acceleration of the pace of life, the quality requirements of food are getting higher and higher. A number of research results have proved that food storage temperature, transportation temperature, fresh-keeping temperature and storage time, transportation time and fresh-keeping time all have a significant impact on the quality of food. Chilled meat is popular for its delicious taste, fresh color and rich nutrition, but its shelf life is relatively short, and its nutrients will decrease with the prolongation of storage time. [0003] Frozen food, such as frozen meat, has a long shelf life. During frozen storage, the quality of frozen meat deteriorates due to material changes such as water sublimation, slow fat oxidation, and protein...
