An Integrated Power and Signal Transmission System A system is described which links by means of a pair of lines the command signals in square waveform from a unit broadcasting such command signals to an operating unit lying a long distance sway so that since the signals are sent at a low voltage of about 36 V and a frequency of about 1 kHz, they are enough after being stored in top quality capacitors to provide power to the operating point at said operating unit, without there being any need to stop power supply when signals are being sent, as used to happen in the previous system. Such system is particularly suitable for the transmiting of operating signals and the receiving of information from a wellhead.
An integrated power and signal transmission system, which joins a signal control and emission station containing a hydraulic power unit, a programmable controller, and a microcomputer, to a remote operating station that receives control signals so that the control signals sent out by the signal control and emission station reach operating points which are connected to and controlled by the remote operating station and at the same time sends information back to said signal control and emission station, when necessary, wherein said integrated power and signal transmission system includes a surface unit, comprising a modem and a modulated source, which directly receives said control signals broadcast by the signal control and emission station, which converts said control signals to modified signals, and which communicates with an electric distribution unit, wherein said electric distribution unit is directly connected to an electronic unit which is enclosed in a housing and which comprises:
