Abstract

The invention, which belongs to the technical field of uranium isotope centrifugation separation, particularly relates to an output signal processing device of a uranium enrichment gas centrifuge rotating-speed sensor. The output signal processing device comprises a channel switch, a filter circuit, a shaping circuit and an output circuit. An original rotating speed signal is gated by the channelswitch to carry out time division processing; the filter circuit carries out filtering to remove high and low frequency clutter interferences; the shaping circuit carries out amplification and shapingand an effective signal is transformed into a standard square wave signal accurately; the output circuit carries out inverse transformation to eliminate accompanied clutters, so that the square wavequality is improved and an ideal square wave signal is outputted. According to the invention, the same kind of device that is introduced from Russia and includes discrete components is replaced completely; the accuracy and speed of the centrifugal machine rotating speed and friction power consumption measurement can be improved obviously; the accuracy and reliability of the detection are improved;the output signal processing device has the great economic and social benefits; and the nuclear fuel production line construction projects continue to increase with continuous expanding of the nuclear fuel centrifugal separation production scale, so that the massive economic benefits are created.

Description

technical field [0001] The invention belongs to the technical field of uranium isotope centrifugation separation, and in particular relates to an output signal processing device for a rotational speed sensor of a uranium enrichment gas centrifuge. Background technique [0002] In the centrifuge cascade process system, the real-time monitoring of the speed and friction power consumption of the gas centrifuge is an important subsystem that must be designed. The signal output by the centrifuge speed sensor is a sine wave analog signal with amplitude and period changes. In order to realize the rapid and accurate measurement of the speed of the gas centrifuge, it is necessary to design a special measuring device and system. In the existing Russian centrifuge speed measurement system, the processing device for the output signal of the sensor is mainly designed and developed based on an analog circuit based on discrete components.
