A master-slave wireless sensor node monitoring system for cold chain logistics

Abstract

The invention discloses a master-slave wireless sensing node monitoring system for cold chain logistics. The master-slave wireless sensing node monitoring system for the cold chain logistics comprises a master node installed on a cold-chain logistics transportation vehicle and powered by a vehicular power supply of the transportation vehicle, multiple slave nodes which are installed in all refrigerated containers on the transportation vehicle dispersedly, a server for monitoring the master node and the slave nodes, and a wireless communication module for performing information interaction between the master node and the slave nodes, and between the master node and the server. The master-slave wireless sensing node monitoring system for the cold-chain logistics can overcome the defects of low transportation reliability, poor using safety and the like in the prior art, and has the advantages of high transportation reliability and good using safety.

Description

technical field [0001] The invention relates to the technical field of cold chain logistics monitoring systems, in particular to a master-slave wireless sensor node monitoring system for cold chain logistics. Background technique [0002] 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 from production, storage, transportation, sales to end users, to ensure food quality and reduce food loss. It is a low-temperature logistics process using refrigeration technology as a means. It is a special logistics form that requires special equipment and attention to the delivery process, time control, and transportation type. [0003] Cold chain logistics is generally divided into four parts: refrigerated (frozen) processing, refrigerated (frozen) storage, refrigerated (frozen) transportation and distribution, and refrigerated (frozen) sales, among which refrigerate...

AI Technical Summary

Problems solved by technology

Therefore, in order to avoid abnormal temperature changes or illegal opening of low-temperature food during transportation, causing food safety problems for consumers after eating, it is necessary to establish a monitoring system for cold chain logistics

[0004] In the process of realizing the present invention, the inventor found that there are at least defects such as low transportation reliability and poor use safety in the prior art
