ABSTRACT:
A centralized data communications system incorporating a plurality of remote stations, each having a plurality of information channels associated therewith. A selected remote station and its associated information channels are tone addressed by a central station communicating with a group of remote stations over a respective communications channel. The remote stations may have a current sensor connected to one of the information channels for sending data corresponding to the amount of current sensed in an electrical path back to the central station upon being properly addressed. This data, together with data representative of the voltage on the monitored electrical path, is used by the central station to calculate energy consumption. The calculated energy consumption is retained at the central station and used for information and billing purposes. The central station may also send data to an addressed information channel at a remote station for controlling an operation thereat. The central station can also receive data from various parameter measuring sensors at a remote station, e.g. sensors measuring temperature, humidity, fluid flow, etc. which may be connected to other information channels and thus the system may be used as a general purpose data gathering or distributing communications system.
