Real-time food freshness monitor and monitoring method thereof

Abstract

The invention relates to a real-time food freshness monitor and a monitoring method thereof. the real-time food freshness monitor is characterized by comprising a master control module, a data acquiring module, a wired sensor, a wireless sensor, a network communication module and a power source module, wherein the master control module is connected with the data acquiring module, the data acquiring module is respectively connected with the wireless sensor and the wired sensor, the master control module is connected with the network communication module, and the network communication module is connected with a remote monitoring center by means of radio communication. The monitoring method includes steps of building a food freshness calculating model; calculating real-time nutrient of food; online monitoring and adjusting proper food storage environment conditions in real time, and transmitting the conditions to the remote monitoring center. By the real-time food freshness monitor and the monitoring method thereof, food freshness can be monitored online in real time, food storage period can be reliably predicted and transmitted to the remote monitoring center, and accuracy, reliability and timeliness of food freshness monitoring are improved.

Description

technical field [0001] The invention belongs to the technical field of food monitoring, in particular to a real-time monitor of food freshness and a monitoring method thereof. Background technique [0002] As we all know, during food transportation and storage, the nutritional value and market commercial value of fresh fruits and vegetables, meat, aquatic products and other foods are closely related to their freshness. The freshness of food is affected by many environmental factors, such as temperature, humidity, and gas emissions in the space, which will cause changes in the freshness of food. At present, the research on food preservation monitoring technology at home and abroad has been very in-depth, but it is also facing some difficult problems: [0003] There are many kinds of food, and the corresponding fresh-keeping monitoring technologies are often different. For the same fruit, the monitored physical and chemical indicators will change with the improvement and rep...

AI Technical Summary

Problems solved by technology

[0006] At present, in the process of food transportation and storage, although there are related products that monitor the temperature and humidity of the fresh-keeping environment, the monitored temperature and humidity are only an objective reflection of the fresh-keeping environmental conditions. Since there are no more access to food fresh-keeping monitoring sensors , There is no real-time nutrient data model introduced in food, and the lack of real-time online intelligent data processing process will inevitably lead to the loss of its practical application significance
