Abstract

A data acquisition device includes 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 the wireless communication unit with data types registered in the type registration unit, a data extracting unit for extracting only data of which the data type matches, and a data holding unit 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 the data accumulation device by wireless communication;

the data acquisition device including;

(a) a first wireless communication unit for performing wireless communication of data;

(b) a first data holding unit for holding data; and

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

the data accumulation device including;

(a) a second wireless communication unit for performing wireless communication of data;

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

(c) a type comparison unit for comparing the data type of data received via the second wireless communication unit with data types registered in the type registration unit;

(d) a data extracting unit for extracting only data of which the data type matches; and

(e) a second data holding unit for holding the extracted data.
