<p><P>PROBLEM TO BE SOLVED: To obtain a telemeter system capable of reducing power consumption. <P>SOLUTION: A simultaneous calling signal from a TM monitoring station 101 is input to a time difference setting device 107 through an IP network 6 and an IP conversion device 105 of each observation station 10, 11, and 12. A power supply command is output to a power supply control device 108 after preset waiting time Tn. The power supply control device 108 supplies a TM observation device 106 with power to making the TM observation device 106 transmit its holding data to the TM monitoring station 101, and stops the power supply after a lapse of predetermined delay timeΔTn from the start of the power supply. The data of the TM observation device 106 is sequentially transmitted to the TM monitoring station 101, where the waiting time Tn is set in the observation stations 10, 11, and 12 so as to slide like T1=1, T2=2, T3=3 sec, and the delay timeΔTn is set to the constant value 0.5 sec. Thereby, the power is supplied to the TM observation device 106 only for a time interval required for data transmission, and power consumption can be reduced. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
