Automatic Control System of Ion Electrostatic Accelerator and Anti-Interference Measures

【摘要】 <正> An automatic control system for the electrostatic accelerator has been developed byadopting the PLC(Programmable Logic Controller)control technique,infrared and optical-fibretransmission technique and network communication with the purpose to improve the intelligencelevel of the accelerator and to enhance the ability of monitoring,collecting and recording parame-ters.In view of the control system’ structure,some anti-interference measures have been adoptedafter analyzing the interference sources.The measures in hardware include controlling the positionof the corona needle,using surge arresters,shielding,ground connection and stabilizing the volt-age.The measures in terms of software involve inter-blocking protection,soft-spacing,time delay,and diagnostic and protective programs.The electromagnetic compatible ability of the controlsystem has thus been effectively improved.更多还原
