MULTIPLEXER SYSTEM FOR AUTOMATIC METER READING

摘要

A multiplexer system (10) for receiving data from a plurality of interrogatable data transmitters (14) coupled to a plurality of telephone lines (12) including means (27) for coupling the multiplexer system to the plurality of telephone lines, means for sending at least one distinct interrogation signal over each of the coupled telephone lines, means (22) for receiving alternating current representations for the data sent over the coupled telephone lines from each of the plurality of interrogatable data transmitters and means (22) for converting each of the alternating current representations of the data into digital representations.
