Centrifugal uranium condensation frequency measurement system control unit

Abstract

The invention belongs to the uranium isotope separation cascade technology frequency measurement data acquisition and automatic control technology field and especially relates to a centrifugal uraniumcondensation frequency measurement system control unit. An Ethernet controller and an upper computer carry out data communication so as to display frequency measurement data and a correlation signal.An LCD controller completes the on-site display of the frequency measurement data and operation personnel checks the data on site. Through I / O input, a button input function is realized, and data checking, shielding, on-site / remote control condition switching and data search functions are realized too. Through I / O output, the collected frequency measurement data is analyzed and processed and thena correlation fault signal is formed. On one hand, the I / O output is used for on-site panel indication and the correlation fault signal is displayed on a control unit panel as a mode of lightening afault lamp; on the other hand, the signal is sent to a Russian control system. The installation mode of a control unit is concise, the control unit can be accessed to the Russian control system in batches, a centrifuge can access the system without shutdown, fund investments are effectively reduced, and the operation stability of a cascade system is comprehensively increased.

Description

technical field [0001] The invention belongs to the technical field of frequency measurement data acquisition and automatic control of uranium isotope separation cascade process, and in particular relates to a control unit of a centrifugal uranium enrichment frequency measurement system. Background technique [0002] The frequency measurement system has been widely used in the centrifugal uranium isotope separation cascade process. At present, the Russian centralized frequency measurement system is used as a subsystem of the centrifugal cascade comprehensive control system. It is mainly responsible for the detection of centrifuge frequency and friction power parameters, Display, analyze, and form an accident alarm signal in an abnormal state and send it to the centrifugal cascade integrated control system for alarm reminder and accident interlock protection action. [0003] Since the system has been in continuous operation for 16 years, the control unit of the Russian freque...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problem that the control unit of the on-site frequency measurement cabinet of the uranium enrichment frequency measurement system is damaged, there is no chip repair of the same type, and it is difficult to replace the frequency measurement system as a whole, the present invention provides a control unit of the centrifugal uranium enrichment frequency measurement system to replace the original Russian control unit. unit, so that it is convenient and economical to access the Russian frequency measurement system
