My Life Goes By My Style

Abstract - Manufacturers have already deployed RFID
technology in products that could be spoiled during
transportation due to temperature extremes. For example,
frozen chicken has a high risk of salmonella contamination if it
becomes too warm for a long time. If the temperature exceeds a
certain threshold, a permanent electrical change occurs in the
RFID-based label. When the RFID reader interrogates the tag,
it will respond with data that indicates the warning state as well
as its ID. In this paper, a mobile diagnosis system based on
RFID (Radio Identification) for food safety is developed. The
developed system consists of a mobile server and a remote
server. In the mobile server, a PDA equipped with RFID CF
Reader Card is used to acquire the food temperatures from
RFID sensors. Moreover, the multi-sensor fusion algorithm is
applied to integrate the sensor information. X-bar chart or
trend chart is used to observe the operation condition of the
food. Subsequently, further analysis can be executed over the
remote diagnosis server, if necessary. And through wireless
network, related personnel can hold an on-line dialogue for
troubleshooting.
