<P>PROBLEM TO BE SOLVED: To provide a telemetering system, capable of easily detecting the state of radio waves between a data collection device and a meter in carrying out telemetering by wireless communication, and performing the accurate and reliable meter reading in an optimum state of radio waves. <P>SOLUTION: The telemetering system acquires metered data of a meter to a data collection device by a wireless communication means, and displays it. The data collection device 1 comprises a radio waves state detecting means 6 for receiving a measuring signal for detecting the state of radio waves transmitted from the meter 2 by a transmission demanding signal, and detecting the state of the radio waves, and a display means 5 for displaying the detection result. The meter 2 comprises a measuring signal generating means 7 for receiving the transmission demanding signal from the data collection device 1, and transmitting the measuring signal for only a predetermined time. <P>COPYRIGHT: (C)2007,JPO&INPIT |
