SYSTEM AND METHOD FOR COLLECTING MEASUREMENT INFORMATION, REPEATING DEVICE, AND PROGRAM

PROBLEM TO BE SOLVED: To transmit measurement information to a collection device 300 mounted on a train with low power consumption. SOLUTION: Measurement devices 100-1 to 100-N and a repeater 200 transmit measurement information between the measurement devices 100-1 to 100-N and the repeater 200 by synchronously switching the respective devices to the operational status operating with a predetermined electric energy. After the completion of the transmission, a switch section 101 of the measurement devices 100-1 to 100-N and a switch section 201 of the repeater 200 switch the respective devices to a power saving condition for the operation with the electric energy lower than the predetermined electric energy. The switch section 201 of the repeater 200, when a detection section 204 detects an approach of a train mounting the collection device 300, switches its own device to an operational status to conduct the transmission between the repeater 200 and the collection device 300. After the completion of the transmission, the switch section 201 of the repeater 200 switches the status of its own device to the power saving condition. COPYRIGHT: (C)2011,JPO&INPIT
