    摘要: Remote stations are connected to utility meters in individual dwellings. A main station is connected to the remote stations via first, second and third transmission lines. The main station applies power and interrogation signals to a selected remote station over the first and third transmission lines. The selected remote station sends data signals representing the meter reading to the main station over the second and third transmission lines in response to the interrogation signals. The main station may further send secondary interrogation signals to the selected remote station by connecting and disconnecting the second and third transmission lines. The selected remote station sends secondary data signals to the main station over the second and third transmission lines in response to the secondary interrogation signals.

    摘要: A system wherein a train of a predetermined number of electrical pulses are generated whenever a predetermined quantity of electricity, gas or water is consumed. The pulses are transmitted to a remotely located data station or the like for remotely measuring the consumed quantity. The received pulse train is processed at a receiving site or the data station so as to derive a single pulse which in turn is counted by a counter.
