PURPOSE:To collect the latest data without imparing the merits of power saving by always monitoring the data unstable state of a sensor means then fetching the data supplied from a sensor to a transmission control means after the data unstable state is released. CONSTITUTION:The water level is measured by a sensor 100 of a telemeter system, and data on the busy state fed from switches SA-SD is supplied to one side of AND gates 302A-302D respectively of a measurement controller 300. While the output of a switch SE is applied to the other side of gates 302A- 302D respectively. At the same time, the output of the switch SE is supplied to a one-shot multivibrator 315. The output of the vibrator 315 is applied to an AND gate 316 and a power supply 200 via a relay coil RCL. The unstable state of the data on the sensor 100 is always monitored, and the data fed from a memory 304 is supplied to a modulator 402 of a communication device 400 after the unstable state of data is released. Thus it is possible to transfer the latest data to a master station without impairing the merits of power saving. |
