Refrigerated transport monitoring system for cold-chain logistics

Abstract

The invention relates to a refrigerated transport monitoring system for cold-chain logistics. The refrigerated transport monitoring system is characterized in that a sensor node module is used for transmitting an electric signal corresponding to acquired environmental data to a signal processing module; the signal processing module is used for transmitting digital signal converted from the electric signal to a central control unit; the central control unit is used for judging whether the digital signal is larger than a threshold or not; if so, the central control unit reads current geographical position information of a refrigerated truck through a positioning module, and determines optimal address information; and meanwhile, the central control unit transmits alarm information generated through a gateway to a cloud server and a mobile terminal respectively. Through adoption of the refrigerated transport monitoring system, the environmental parameters of temperature, moisture and air pressure can be monitored in real time in order to prevent cold-chain products from deteriorating in a refrigerated transport process. Meanwhile, the mobile terminal also displays the address of a refrigeration station closest to the current position of the refrigerated truck in real time, so that transport personnel can transfer the cold-chain products immediately, and product deterioration due tounexpected failure of refrigeration equipment is further reduced, thereby reducing economical loss.

Description

technical field [0001] The invention relates to the technical field of cold chain logistics transportation, in particular to a refrigerated transportation monitoring system for cold chain logistics. Background technique [0002] Cold Chain Logistics (Cold Chain Logistics) generally refers to a systematic project in which refrigerated and frozen foods are always kept in a specified low temperature environment in all links of production, storage, transportation, sales and consumption to ensure food quality and reduce food loss . With the development of social economy and the improvement of people's living standards, people's demand for cold chain logistics is increasing, and at the same time, the quality requirements for products transported by cold chain logistics are also gradually increasing. [0003] The products transported by cold chain logistics can generally be divided into three categories, namely primary agricultural products (including vegetables, fruits, meat, pou...

AI Technical Summary

Problems solved by technology

[0004] Based on this, it is necessary to address the abnormal changes in the environment inside the refrigerated vehicle during the transportation and distribution process in the cold chain logistics, which cannot be detected by the transport personnel in time, which will easily lead to the product being spoiled in the abnormal environment for a long time , deterioration problem, provide a refrigerated transportation monitoring system for cold chain logistics
