MEDIUM COMMUNICATION SYSTEM USING LOG DETECTOR AMPLIFIER

摘要

An in-medium monitoring system for monitoring material carried within a pipe. The system includes an acoustic device installed within the pipe that generates voltage signals indicative of changes in the material, such as flow rate or leaks, a hardware unit that includes a detector module and a communication module, a switch for switching the voltage signals to and communication signals from the hardware unit. The hardware unit and a power source are attached to the pipe. The acoustic device may be detector or a sensor. The communication module may communicate date through the sensor in the medium or outside of the pipe to a fixed network. The hardware unit may include a log detection amplifier for generating an amplified pulsed output signal without voltage gain and without significantly adding noise.

1. An in-medium monitoring system for monitoring material carried within a pipe, comprising:
an acoustic device installed within the pipe and configured to at least generate a voltage signal indicative of changes in the material; a hardware unit including a detector module and a communication module; a switch connected to the acoustic detector for switching the voltage signal to the hardware unit; and a power source for the acoustic device, the hardware unit and the switch, wherein the hardware unit and power source are attached to the pipe.
