Abstract

A data transmission system which may be used in any industrial installation in which an A.C. powered device is remotely located and in which it is desired (i) to monitor certain parameters, and/or (ii) to control certain operational functions at the remote site. The power cable used to carry A.C. power to the remotely operating device is also used to carry instrumentation, communication, and control signals from the local control and readout equipment located at the surface to an instrumentation and control package installed at the remote site in the down-hole location. The present invention comprises means for the simultaneous bidirectional transmission of digital data between the local and remote sites by means of a modulated D.C. loop current to thereby accomplish the required monitoring and control functions.
