In this study, we develop the monitoring system of marine refrigerated containers based on RFID temperature tag to make up for the shortcomings that the traditional system only depended on supply air temperature or return air temperature of the container to reflect the cargo temperature. The RFID temperature collection tags, the RFID reader and the software are designed and developed. Results of the inside temperature monitoring experiment showed that the system featured multi-points real-time monitoring, 100% readability, long reading distance and rapid reflection of the temperature variation, which may effectively solute the problem of cargo damage caused by uneven temperature distribution inside the container.
