Master-slave wireless sensing node monitoring system for cold-chain logistics

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.
