Cold-chain transport temperature monitoring and early warning method and system

Abstract

The invention discloses a cold-chain transport temperature monitoring and early warning method and system. The cold-chain transport temperature monitoring and early warning method is characterized in that a wireless sensing network is established to acquire temperature data in carriers in real time by Zigbee, the temperature during cold-chain transport can be monitored and warned early, and an early model is learned from the historical temperature data acquired based on the BP neural network in real time. The cold-chain transport temperature monitoring and early warning system can analyze the monitored temperature data in real time by the aid of the early warning model, and can automatically warn by short messages if the predicted results exceed the set warning threshold, so that alarming and early warning of the cold-chain temperature can be realized.

Description

technical field [0001] The invention relates to the technical field of cold chain transportation, in particular to a method and system for temperature monitoring and early warning of cold chain transportation. Background technique [0002] Cold chain transportation is an important means to ensure the quality of perishable food. As a new type of chicken, chilled chicken has the characteristics of rich nutrition, safety and hygiene. Chilled chicken, as a high-quality chicken, will gradually increase its market share, and major cities such as Beijing, Shanghai, and Guangzhou are vigorously promoting chilled chicken. Based on the clear regulations on the temperature of chilled chicken cold chain transportation, the temperature during cold chain transportation of chilled chicken needs to be kept at 0-4°C, and severe temperature fluctuations will have an adverse effect on the quality of chicken, so chilled chicken Transportation personnel need to know the temperature inside the r...

AI Technical Summary

Problems solved by technology

The driver of the refrigerated truck cannot get temperature alarm and early warning information, which is not conducive to real-time adjustment of the temperature in the refrigerated truck compartment

Taking the transportation of chilled chicken as an example, the temperature in the refrigerated compartment exceeds 4°C, which will affect the quality of the chilled chicken, and even cause it to spoil; on the contrary, if the temperature is lower than 0°C, it will adversely affect the quality of the chilled chicken and cause excessive energy consumption. More consumption, increased transportation costs
