| Abstract | This thesis describes the control circuitry for a telemetry system developed to report hydrologic information from remote locations. The multiparameter, on-call system operates on a single frequency. Each remote station responds to a predetermined number of pulses from the master station. Data is transmitted by pulse- duration modulation. In the preliminary planning, careful consideration was given to the system reliability, the energy requirements of the remote station and to system flexibility. The reliability of the system is first examined theoretically by demonstrating that only the catastrophic failure of one or more parts will result in a system failure and that the mean time between such failures is 8.9 years. The system reliability was next examined by observing its operation at reduced voltage over a wide range of temperatures. This reliability was achieved at an energy level which allows a winter of operation from a battery of reasonable size. The system is shown to be flexible in a variety of wars. It can be operated with various types of radio equipment and with slight changes during construction at various frequency bandwidths. The system is flexible, both as regards the number of remote stations which can be operated with a master station and the number of parameters which can be telemetered by a remote station. Furthermore, the system is compatible with a wide variety of measurement transducers. The system presented should prove satisfactory for many applications in addition to the one for which it was designed. |
