Abstract:

Online supervision on key indicator of storage transportation environment and quality maintains in fresh agricultural products cold chain process can effectively improve the cold chain logistics service quality and reduce loss of perishable products logistics, guarantee food security and maintain superior quality. This article introduced the research progress on monitoring technology in cold chain logistics, combining with the research hotspot field where recently wireless sensor (WSN) technology was applied in monitoring cold chain logistics process, and then carried analysis from the following 4 aspects respectively: energy consumption, transmission stability, all sideness monitoring and particularity of agricultural products. This paper also put forward the existing problems in cold chain monitoring technology and the development trend in future.

Key words: cold chain logistics, agricultural product, WSN
