Research on Application of WSN in Cold Chain Logistics’ Warehousing and Transportation

Abstract

Cold Chain Logistics has been closely surrounding the people in their own life, which nearly contains all the perishable food. In Cold Chain Logistics, warehousing and transportation are the parts that are most liable to accidents. Regarding the cold-chain food’s safety as the starting point and combining with the requirements of warehousing and transportation, the paper adopts Wireless Sensor Networks (WSN) technology, Zigbee network technology to build the intelligent monitoring system of three-tier framework containing perception control-network transmission-application service. That is to say, the various types of sensors are placed in warehouses, carriages and packaging of goods to monitor environment information such as temperature humidity, illumination, behaviors of goods in real time. And based on maximum similarity’s multiple characteristic recognition (MSMCR), the decision method of fuzzy control, the monitoring terminal analyses the information and makes the judgment in time to adjust the environmental factors automatically, which realize real-time intelligent monitoring and visible management in warehousing and transportation.
