Integrated power and signal transmission system.

摘要

A system is described which links by means of a pair of lines the command signals in square wave form from a unit broadcasting such command signals to an operating unit lying a long distance away so that since the signals are sent at a low voltage of about 36V 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 transmitting of operating signals and the receiving of information from a wellhead.
