Abstract:

The storage environment of ‘Fuji’ apple was real-time monitored to ensure quality security of ‘Fuji’ apple saved on long term in the cold storage. In this paper, based on the transmission technology of Zigbee and GPRS, we designed a series of data acquisition nodes, which combined Zigbee with the temperature sensors, humidity sensors, CO2 sensors and C2H4 sensors, and constructed a wireless sensor network in the cold storages. Furthermore, the early-warning System for ‘Fuji’ Apple Quality Security was designed with the J2EE technique, which realized data collection, real-time monitoring and early-warning. The tests of PRR (packet reception rate) were carried out within the environment which was in temperatures 0℃ at RH (relative humidity) 90% and CO2 1%. The results showed that, the packet reception correct rate was above 80%. The system could be used into environmental information collection, environmental monitoring and environmental early-warning in the cold storage.
