Abstract

Provided is a data storing apparatus and method for Radio Frequency Identification (RFID) tags with sensors. The apparatus includes: a first storing block which includes a kill password storage and an access password storage; a second storing block which includes an Electronic Product Code (EPC) storage, a protocol control storage, and an error check storage storing a Cyclic Redundancy Checking (CRC) code for detecting a transmission error; a third storing block which includes a tag identifier storage storing a tag identifier including a manufacture model and a serial number of the tag; and a fourth storing block which includes an initial sensor data storage storing initial information of the sensor, a real-time information storage, a maximum/minimum data storage storing maximum/minimum values, a sensor data storage storing sensing data actually measured through the sensor embedded in the RFID tag.

Claims

1. An apparatus for storing data of Radio Frequency Identification (RFID) tags having sensors, comprising:

a controlling means for controlling the data from the sensors to be stored; and

a storing means for storing the data from the sensors,

wherein the storing means includes;

a first storing unit which includes a kill password storage storing a kill password that an RFID reader transmits to an RFID tag in order to halt operation of the RFID tag, and an access password storage storing an access password of the tag;

a second storing unit which includes an Electronic Product Code (EPC) storage storing a code for identifying an object having the tag, a protocol control storage having physical-layer information of the code storage, and an error check storage storing a Cyclic Redundancy Checking (CRC) code for detecting a transmission error;

a third storing unit which includes a tag identifier storage storing a tag identifier including a manufacture model and a serial number of the tag; and

a fourth storing unit which includes an initial sensor data storage storing initial information of the sensor, a real-time information storage storing information of year, month, day, time, minute and second, a maximum/minimum data storage storing maximum/minimum values compared to set up an excess/validity region of the sensing data, and a sensor data storage storing sensing data actually measured through the sensor embedded in the RFID tag.

2. The apparatus as recited in claim 1, wherein initial information of the sensor includes type information of the sensor embedded in the tag, type information of the tag including the sensor, and sensing time interval information of the tag including the sensor.

3. The apparatus as recited in claim 1, wherein in a process for storing data acquired from the sensor embedded in the tag in data storing apparatus for the RFID tags with sensors, sensing data inputted in real-time are compared/calculated with the maximum/minimum values of the maximum/minimum data storage, and the sensing values of the maximum/minimum excess regions are stored in the RFID tag data storing apparatus.

4. The apparatus as recited in claim 3, wherein when the sensing value of the maximum/minimum excess regions are stored, and only the corresponding value is stored by a command of a reader or a value pre-designated when the tag is manufactured.

5. The apparatus as recited in claim 1, wherein in a process for storing data acquired from the sensor embedded in the tag in the data storing apparatus for RFID tags with sensors, sensing data inputted in real-time are compared/calculated with the maximum/minimum values of the maximum/minimum data storage, and the sensing value of only a validity region is stored.

6. The apparatus as recited in claim 1, wherein in a process for storing data acquired from the sensor embedded in the tag in the data storing apparatus for RFID tags with sensors, only a difference between neighboring two data inputted in real-time is stored.

7. A method for storing data of Radio Frequency Identification (RFID) tags having sensors, comprising the steps of:

a) controlling the data from the sensors to be stored on a storing means,

wherein the storing means includes;
