PURPOSE:To collect satisfactorily the latest data without imparing power saving by transferring the idle data to a master station in case the polling is applied to a busy state, and renewing data after releasing the busy state to transfer the renewed data to the master station. CONSTITUTION:The water level is measured by a sensor 100 of a telemeter system, and the busy state obtained when the polling is applied from each of switches SA-SD is supplied to AND gates 302A-302D of a measurement controller 300. While the output of a switch SE is supplied to the other side of the gates 302A-302D and one side of AND gates 306 and 310 respectively. The outputs fed from gates 302A-302D are supplied to a memory 304, and the idle data is transferred to a master station from a communication device 400. Then the output of an FF is supplied to the gates 306 and 310, and the outputs of gates 310 and 306 are supplied to a timer 312 and the memory 304, respectively. The data of the memory 304 is renewed after the busy state is renewed. Then a relay switch RS is actuated to transfer the latest data to the master station. |
