摘要： A telemetering system permits multiple functions to be monitored in response to each interrogation pulse by utilizing multiple sets of reply frequencies to distinguish between simultaneous reply pulses. The status of the various functions is displayed on a color television screen segmented into a grid wherein the color of each grid location represents the status of a respective monitored function. Remote utility meter reading is effected using a single reply pulse per interrogation by monitoring only one dial of a multiple-dial meter for intervals of angular motion of the indicator and updating a total accumulated count at the central station each time a unit of fractional revolution is sensed. In a preferred embodiment, telemetering is effected via a coaxial cable dedicated solely to the telemetering system.
