Study on the Construction of the Digital Telemetry Systern with High-Performance Characteristics
抄録
A new digital telemetry system for monitoring the liquid surface level is presented to realize the high -perfomance system with very low power consumption and high reliability. In the proposed system, the electric power is supplied to each circuit from the battery during only the operating time interval when the signals are measured, processed and transmitted. During the waiting time inte~val, the main switch is in off-state and the power consumption of this system can be disregarded. The circuit configuration of the new digital telemetry system is described first. Next, the power consumption characteristics are analyzed and compared on the conventional and new systems. As a result, it is clearly demonstrated that the new system is superior to the conventional one and can be used for five years or more without the maintenance of the battery. Further, it is clarified that the simpler method for the error correcting code can be used in the new system.
