Abstract

Processing efficiency of acquired data is improved by restricting saving or acquiring of unnecessary data. A data acquisition device 110 includes a communication unit 214 for performing wireless communication of data with a data accumulation device 100 in which data is accumulated, a type registration unit 216 wherein data types of necessary data are registered beforehand, a type comparison unit 218 for comparing the data type of data received via the wireless communication unit with data types registered in the type registration unit, a data extracting unit 220 for extracting only data of which the data type matches, and a data holding unit 222 for holding the extracted data.

Claims

1. A data transfer system comprising:

a data accumulation device for accumulating data; and

a data acquisition device for acquiring data from said data accumulation device by wireless communication;

said data acquisition device including

a first wireless communication unit for performing wireless communication of data,

a first data holding unit for holding data, and

a data transmission unit for transmitting data held in said first data holding unit to said data acquisition device via said first wireless communication unit, in the event that said data accumulation device is within a communicable range;

and said data accumulation device including

a second wireless communication unit for performing wireless communication of data,

a type registration unit wherein data types of necessary data are registered beforehand,

a type comparison unit for comparing the data type of data received via said second wireless communication unit with data types registered in said type registration unit,

a data extracting unit for extracting only data of which said data type matches, and

a second data holding unit for holding said extracted data.

2. A data acquisition device comprising:

a wireless communication unit for performing wireless communication of data with a data accumulation device in which data is accumulated;

a type registration unit wherein data types of necessary data are registered beforehand;

a type comparison unit for comparing the data type of data received via said wireless communication unit with data types registered in said type registration unit;

a data extracting unit for extracting only data of which said data type matches; and

a data holding unit for holding said extracted data.

3. The data acquisition device according to claim 2, further comprising a skip instruction unit for causing said data accumulation device to skip transmission of data of which the data type has been determined to not match at said type comparison unit;

wherein communication of data of which said data type does not match is not performed.

4. The data acquisition device according to claim 2, wherein said data is structured of sub-data units distinguished by data type, and each sub-data unit is structured of data type and data length serving as data header information, and a data body, in that order;

and wherein said data extracting unit removes the data body of the length indicated in said data length in the event that said data type does not match.

5. The data acquisition device according to claim 2, wherein said type registration unit is capable of registration of data types of unnecessary data;

and wherein said data extraction unit omits from extraction only data of which the data type matches that of said unnecessary data.

6. The data acquisition device according to claim 2, wherein said wireless communication is performed using a Near Field Communication standard.

7. The data acquisition device according to claim 2, wherein said data is sectioned into 16-byte blocks.

8. A program for causing a computer to have the functions of:

an acquisition communication unit for performing wireless communication of data with a data accumulation device in which data is accumulated;

a type registration unit wherein data types of necessary data are registered beforehand;

a type comparison unit for comparing the data type of data received via said wireless communication unit with data types registered in said type registration unit;

a data extracting unit for extracting only data of which said data type matches; and

a data holding unit for holding said extracted data.

9. A data acquisition method for acquiring data by wireless communication from a data accumulation device in which data is accumulated, said method comprising:

a type registering step wherein data types of necessary data are registered beforehand;

a data receiving step wherein data is received from said data accumulation device;

a type comparing step wherein the data type of data received is compared with data types registered in said type registering step;

a data extracting step wherein only data of which said data type matches is extracted; and

a data holding step wherein said extracted data is held.

10. A data accumulation device comprising:

a wireless communication unit for performing wireless communication of data;

a data holding unit for holding data;

a data transmission unit for transmitting data held in said data holding unit to said data acquisition device via said wireless communication unit, in the event that a data acquisition device for acquiring data from said data accumulation device is within a communicable range; and

a skip execution unit for causing transmission of data of predetermined data types to be skipped, in response to instructions from said data acquisition device.

11. The data accumulation device according to claim 10, wherein said data is structured of sub-data units distinguished by data type, and each sub-data unit is structured of data type and data length serving as data header information, and a data body, in that order;

and wherein said skip execution unit causes the data body of the length indicated in said data length to be skipped for sub-data units belonging to predetermined data types, in response to instructions from said data acquisition device.

12. The data accumulation device according to claim 10, wherein said wireless communication is performed using a Near Field Communication standard.

13. The data accumulation device according to claim 10, wherein said data is sectioned into 16-byte blocks.

14. The data accumulation device according to claim 10, wherein said data accumulation device is an IC tag.

15. A program for causing a computer to have the functions of:
