MINIATURE WIRELESS SENSOR, MEMS BASED, APPLICATION IN COLD CHAIN (FOOD/MEDICINE PROCESS) LOGISTICS WITH REAL TIME TEMPERATURE DATA STORAGE AND REMOTE DATA ACCESS USING SUPER RFID.
The cold chain logistics is a systematic project which ensure the temperature-sensitive product under the pro-established low temperature in every process of productionâ„¢s storage, transportation and sale which can make sure the products quality and reduce the logistics loss, Since the environment is changing vastly, and due to the limitation of tech and cost , the risk of quality accidents due to the goods temperature change in the process of transportation and dispatching is more often than in other process. Moreover, in common situation, the closeness of transportation and dispatching process always makes more difficulties for the next accident survey works, that is when and where the goods temperature began to fall outside the limitation range. On the other hand, whether it is caused by an unexpected environmental factor or a persistent error of cold storage system The resolution for these problems is a kind of tech, which can constantly record and store the goods temperature and send the temperature data to the back-stage management system.
With the rapid growth of RFID tech and MEMS applications, the important role of temperature sensing system based on active RFID tech is more and more convinced in the industry with miniature sensor apart. Active RFID tag can achieve real-time temp data though MEMS based temp sensor and store the data during all process, then transmit them the connected RFID tag memory, then the data in the tag can be read once the tag appear in the range of reader. The reader can read many tags simultaneously. The tags data is analyzed and entire data stored during the process will be displayed on the PC It also alert if the particular tag undergoes above permitted temperature level. The reader is connected to a base processor and then feed to a PC with installed software.
