Abstract: A serial terminal (9) for a serial connection to a target device for data acquisition, a data transfer terminal (12) to be connected to a mobile phone (5) so as to allow a data transfer, a data acquisition portion (13) for acquiring device data from the target device for data acquisition by a serial communication via the serial terminal, a data transfer portion (14) for adding transmission instruction data to the device data so as to create transfer data and transferring the transfer data via the data transfer terminal, and a control portion (15) for executing an operation of acquiring the device data by the data acquisition portion and an operation of transferring the transfer data by the data transfer portion are provided, and the transmission instruction data correspond to an instruction to cause the mobile phone to conduct an operation of transmitting the device data to a predetermined server via the internet.

Abstract: A data collection system includes: a server (7) connected to the Internet (6); a plurality of data acquisition target devices (1); and a plurality of data transfer devices (3) that can be connected to the data acquisition target devices, respectively. Device data acquired by each data transfer device from each data acquisition target device are transferred to the server via the Internet using a mobile phone (5). The data transfer device includes: a data acquisition part (13) for acquiring the device data from the data acquisition target device; a data transfer part (14) for combining transmission instruction data with the device data so as to generate transfer data, and transferring the transfer data to the mobile phone; and a control part (15) for allowing the operation of acquiring the device data and the operation of transferring the transfer data to be executed.
